Moreover, as long as the cylindrical member 1 and the end surface members 2a and 2b do not give the small animal D a feeling of occlusion, they may be translucent.

The pair of frames 4 and 5 are attached around the edge of the cylindrical member 1, are formed in an annular shape corresponding to the cylindrical member 1, and are made of a lightweight aluminum-based metal material in the present embodiment. One frame 4 fixes the end face member 2 a to the cylindrical member 1, and the other frame 5 can be engaged with the opening / closing mechanism 6. As shown in detail in FIG. 3, the frame 4 is fixed so as to be fitted to the outside of the one end 1 a of the cylindrical member 1, and the edge of the end surface member 2 a is inserted into the inner peripheral surface. More specifically, the frame 4 has a two-member joining structure so that the edge of the end face member 2a can be sandwiched. As shown in detail in FIG. 3, the other frame 5 is fixed so as to be fitted to the outside of the other end 1 b of the cylindrical member 1.
The frame 4 and the frame 5 are connected by a tie rod 8 disposed in the axial direction outside the cylindrical member 1.
Furthermore, support legs 10 for supporting the cylindrical member 1 at a certain height are attached to the frames 4 and 5.

The tie rod 8 fixedly connects the frame 4 and the frame 5 and also selectively connects the opening / closing mechanism 6. The tie rod 8 includes a plurality of round bars arranged at equal intervals in the axial direction outside the cylinder member 1. Thus, in this embodiment, twelve are arranged at intervals of 30 °. A male screw is formed at the end of the tie rod 8 on the frame 4 side, and is fixed to the frame 4 by a nut 18. The tip of the tie rod 8 on the side of the frame 5 is provided with a groove portion 8a formed of an annular groove, and an engaging portion 8b that matches the outer diameter of the tie rod 8 at the tip that is continuous with the groove portion 8a. It protrudes to the opening / closing mechanism 6 side through the formed hole 5a.
The length W1 from the frame 5 to the groove 8a of the tie rod 8 is set to be longer than the diameter in the contracted state of the packing 7 described later and shorter than the diameter in the expanded state. The length W2 of the groove 8a is set equal to or slightly longer than the thickness of a lock plate 9a described later.

The opening / closing mechanism 6 is formed in an annular shape corresponding to the frame 5, and the edge of the end surface member 2 b is inserted into the inner peripheral surface. The opening / closing mechanism 6 and the frame 5 are rotatably connected by a hinge 14. In other words, the opening / closing mechanism 6 is configured so that the end surface member 2b becomes an opening / closing door with respect to the cylindrical member 1.
Further, the opening / closing mechanism 6 is provided with holes 6 a for inserting the tie rods 8 at positions corresponding to the tie rods 8.
Further, the opening / closing mechanism 6 is provided with an engagement structure 9 for engaging with and disengaging from the engagement portion 8 b of the tie rod 8.

  The packing 7 secures the airtightness between the opening / closing mechanism 6 and the frame 5, and as shown in FIGS. 1 and 4, the packing 7 has an expansion / contraction property attached to the contact surface of the frame 5 with the opening / closing mechanism 6. It consists of an annular tube made of a rubber material or the like. A supply pipe 16 is connected to the packing 7 through a branch valve 15 in the middle of a pipe from a compressor or the like (not shown) for supplying air to the container body 3 to the supply pipe 13a.

The engagement structure 9 is for engaging and detaching the opening / closing mechanism 6 to / from the engaging portion 8b of the tie rod 8, and is rotatably incorporated in the opening / closing mechanism 6 as shown in detail in FIG. An annular lock plate 9a, an operation bar 9b attached to the lock plate 9a and projecting from the opening / closing mechanism 6, and a plurality of engagement holes 9c drilled in the lock plate 9a. The engaging hole 9c has a gourd shape in which a large hole that matches the engaging portion 8b of the tie rod 8 and a small hole that matches the outer diameter of the groove 8a of the tie rod 8 communicate with each other. It is getting narrower. Twelve of the same number of engagement holes 9c as the tie rods 8 are drilled at the same intervals as the tie rods 8 are disposed.
Note that the number of tie rods 8, the number of holes provided in the opening / closing mechanism 6, and the number of engagement holes 9 c are not limited to the above-described twelve, but may be the same.

The floor 11 constitutes a horizontal stable surface on which the small animal D is placed. The floor 11 is a lightweight aluminum-based metal plate that is horizontally stretched on the bottom side of the cylindrical member 1 of the container body 3. It has a half-moon shaped end face part 11b. The spanning surface of the floor 11 is set higher than the connection position of the pipes 13 a to 13 c described above, and a gap is formed in the lower portion of the floor 11. The floor 11 has a large number of slits 11a through which air passes so as to extend in a direction perpendicular to the axial direction. The end surface portion 11b has a plurality of holes 11c through which air passes.
The floor 11 is detachably attached and can be replaced every time it is used.

The support legs 10 support the container body 3 at a constant height, and are composed of four square legs attached to the frame 4 and the frame 5.
In the present embodiment, as shown in FIG. 3, the container body 3 is installed in two vertical stages, but the present invention is not limited to this. Multiple stages can be installed.

  According to this embodiment, since the cylindrical member 1 and the end surface members 2a and 2b of the container body 3 can be assembled by being fitted and inserted into the frame 4 and the opening / closing mechanism 6, the pressure resistance of the container body 3 is complicated. Work becomes unnecessary, and cheap and easy manufacture becomes possible.

Next, a method for using the high-pressure air supply device according to the present embodiment will be described. First, in a state where the end face member 2b is opened by the opening / closing mechanism 6 having an opening / closing door structure, the small animal D is placed inside the container body 3 and placed on the floor 11. Then, the container 3 is closed by closing the opening / closing mechanism 6 with respect to the frame 5 and engaging the engaging structure 9. In order to perform the engaging operation of the engaging structure 9, first, as shown in FIG. 6 (A), the tie rod 8 facing the engaging hole 9c is shown in FIGS. 5 (A) and 6 (B). In this manner, the engaging portion 8b is positioned in the large hole portion of the engaging hole 9c. Thereafter, using the groove portion 8a of the tie rod and the engagement hole 9c as a guide, the lock plate 9a is rotated by lowering the operation bar 9b in the downward direction as shown in FIGS. 5 (B) and 6 (C). The groove 8a is positioned in the small hole portion of the engagement hole 9c. At this time, since the opening width is gradually narrowed from the large hole to the small hole, even if there is a slight manufacturing error between the outer diameter of the groove 8a and the outer diameter of the small hole portion of the engagement hole 9c. Can be performed reliably.
Since the opening / closing mechanism 6 is fixed to the frame 5 by the engagement structure 9, the opening / closing mechanism 6 cannot be opened from the inside of the container body 3, and the small animal D comes out from the inside. Can be prevented. Further, the container body 3 can be closed by engaging the engaging portions 8b of all the tie rods 8 and the engaging holes 9c of the lock plate 9a at a time only by rotating the lock plate 9a.
At this time, the packing 7 is contracted because air is not supplied from the supply pipe 16, and a gap is formed between the frame 5 and the opening / closing mechanism 6.

  Thereafter, air is supplied into the container body 3. At this time, the air supplied from the supply pipe 13a flows into the gap between the floor 11 and the bottom side of the cylindrical member 1 of the container body 3 to disperse the air and attenuate the air supply sound. In addition, when air passes through the slits 11a and the holes 11c of the floor 11, the air is dispersed and the air supply sound is attenuated. Therefore, the inside of the container 3 can be quickly placed in an appropriate pneumatic atmosphere, and the sound that makes the small animal D feel uncomfortable and fearful can be eliminated. In addition, when the rough mat 17 is laid on the floor 11, the dispersion of air and the attenuation of the air supply sound are promoted. In addition, the slit 11a of the floor 11 functions as a discharge port for urine excreted by the small animal D. However, by making the mat 17 water-absorbing, it absorbs a small amount of urine and absorbs air. Can also be dried. This mat 17 is removable and can be replaced every time the small animal D is used.

  When the inside of the container body 3 is placed in an appropriate pneumatic atmosphere, the pressure deformation in the respective directions (radial direction, axial direction, etc.) of the cylindrical member 1 and the end surface members 2a and 2b of the container body 3 is caused by the frame 4. And 5, it is blocked by the connecting structure of the opening / closing mechanism 6 and the tie rod 8. In addition, since the tie rods 8 are installed at equal intervals, the pressure is dispersed. As a result, effective pressure resistance is maintained in the container body 3 and unnecessary leakage of air is avoided.

Air supplied to the inside of the container body 3 is also supplied from the supply pipe 16 to the packing 7 via the branch valve 15. At this time, the packing 7 contracted as shown in FIG. 4 (A) expands as shown in FIG. 4 (B) and closes the gap between the frame 5 and the opening / closing mechanism 6. From this, the airtightness of the container body 3 is ensured reliably. At this time, since outward pressure is applied to the opening / closing mechanism 6, the lock plate 9a and the wall surface 8c of the engaging portion 8b are brought into close contact with each other, and the airtightness of the container body 3 becomes more reliable. .
When the supply of air to the inside of the container body 3 is stopped, the supply of air to the packing 7 is also stopped and the packing 7 contracts. As a result, even if the supply of air is stopped unexpectedly due to a power failure or the like, the airtightness between the frame 5 and the opening / closing mechanism 6 is released, so that outside air enters through the gap and is accommodated in the container body 3. Animal D will not be oxygen deficient.

  Furthermore, since the container body 3 is composed of the transparent cylindrical member 1 and the end face members 2a and 2b and is transparent as a whole, the small animal D does not feel a strong sense of blockage or fear, and is effective in injuries. Promotion of recovery and relaxation effects can be obtained.

  As described above, in addition to the illustrated example, both end surface members 2a and 2b of the container body 3 can be opened and closed.

  Furthermore, it is also possible to install the cylinder member 1 vertically by making the axial direction of the cylinder member 1 vertical.

  The high-pressure air supply apparatus according to the present invention is small by placing appropriate equipment, such as using the airtightness of the container body as watertightness, in addition to placing small animals in a special pneumatic atmosphere. It can also be used for the purposes of animal cleaning, disinfection, treatment, etc.
