Description

[Detailed description of the invention] The present invention relates to a bovine nose ring.

It is common practice to attach a nose ring to cattle when raising them. However, when grazing, for example, if the nose ring is worn while grazing, the nose ring may get caught on a tree or rock, causing problems such as the nose being cut. However, even if the nose ring is made easy to remove, it may come off inadvertently, and if the nose ring cannot be removed without being cut, this is inconvenient when it is desired to remove it as described above. For example, Japanese Utility Model Publication No. 50-15975 and Utility Model Application Publication No. 18213 of 1932 disclose techniques for making the nose ring part and the connector detachable. However, this technique involves first making a hole in the cow's nose and then passing the nose ring through it, which causes pain to the cow. For this purpose, Japanese Patent Application Laid-open No. 136780 (1983)
15087), a technique is disclosed in which a tool is used to pierce and simultaneously insert a nasal ring into the nasal septum of a cow. Since the nose ring cannot be removed in this known technique, it has the disadvantages mentioned above.

Therefore, an object of the present invention is to provide a cow nose ring that does not come off naturally once it is attached to a cow, and that can be easily removed manually if it is desired to be removed.

According to the present invention, in a bovine nose ring that serves as a connecting device that connects a nose ring portion made of an elastic material in a C-shape and both ends of the nose ring portion, engaging portions are provided at each end of the nose ring portion. The engaging portions include a non-circular locking piece that extends outward from the outside diameter of the nose ring portion, and a non-circular locking piece that extends further in the axial direction from the locking piece, and the nose ring portion also has a small outside diameter. It consists of an extension part and a conical insertion part provided at the tip of the extension part,
The insertion portion of one of the engagement portions is provided with a notch at a position opposite to the other in the diametrical direction, and the coupling device has openings in a shape compatible with the locking piece at both ends, and a partition wall in the middle. It also has a pair of tongues that are inclined inwardly from near each end, and the dimension between the tips of the pair of tongues is the same as the dimension between the notches, and Adjacent to the opening, a recessed portion is formed with an enlarged size that allows the locking piece to rotate.

Therefore, the engaging portion without the notch is inserted into the connector in advance. Then, the insertion portion without the notch is engaged by the tongue piece, so that one end of the nose ring body and the connector are fixed. If you are making a hole in the nasal septum of a cow for the first time, for example
Using the known tool described in the above publication, the hole is pierced in a so-called one-touch manner, and at the same time, the engaging portion with the notch portion is connected to the connecting tool. For cattle that already have a hole in their nasal septum, it is sufficient to pass the insertion portion with the notch through the hole and engage the connector with one end of the nasal ring portion with the notch.

When removing the nose ring, press the nose ring part so that both inserted parts hit the middle chamber. The locking piece will then be located at the enlarged portion, allowing the coupling to rotate. Then, by aligning the notch with the tongue, it can be removed.

In this way, in the present invention, since the locking piece is engaged with the opening in the normal state, the connector cannot be rotated by the non-circular locking piece, but when it is removed,
The coupling can be rotated relative to each other by manually pressing and moving the locking piece to the enlarged part.
It will not come off inadvertently.

Therefore, in the present invention, the connecting tool is easy to connect, can be performed at the same time as the piercing of the nasal septum, and is easy to remove, but does not come off naturally. Therefore, it improves work efficiency as a nose ring for cows.

In addition, when implementing the present invention, it is preferable to use a square-shaped locking plate as the locking piece.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a nose ring body A embodying the present invention,
The nose ring part 1 is made of an elastic material such as synthetic resin, metal, etc. and has a C-shape as a whole, and engagement parts indicated as E ₁ and E ₂ are provided at both ends of the nose ring part 1. . This engaging part E ₁ is the nose ring part 1
A locking plate 2 having a non-circular shape (square in the illustrated embodiment) is formed at the end of the nose ring portion 1 and extends outward from the outer diameter of the nose ring portion 1. It includes an extension part 3 extending in the direction and having a smaller outer diameter than the nose ring part 1, and a conical insertion part 4a formed at the tip of the extension part 3. Also, a notch 5 is located at a position opposite to that in the diametrical direction.
is provided. The other engaging portion E ₂ is also substantially the same as the engaging portion E ₁ except that the aforementioned notch 5 is not provided in the insertion portion 4b. The nose ring portion 1 can be closed in the X direction in FIG. 1 due to its elastic force.

As shown in _FIG .
The length of one side is approximately equal to the outer diameter of the bottom of the conical insertion portion 4a, and therefore the length between the notches 5, 5 formed opposite to each other is approximately the outer diameter of the extension portion 3. are created equal.

Next, an embodiment of the connector B will be described with reference to FIGS.
The connector B is generally formed into a rectangular parallelepiped shape, and openings 10 are formed on both sides thereof. This opening 10 is made in a shape compatible with the aforementioned locking plate 2, and is square in the illustrated embodiment. It has side walls 11 on both sides, and a partition wall 6 in the middle. Further, the side portion 12 on the other side is provided with holes 12a and 12b so that the engaged state of the insertion portions 4a and 4b can be seen from the outside as described later. As can be seen from Fig. 3 A, D and Fig. 4, the tongue piece 7 is provided so as to be inclined inwardly from near both ends
a, 7a and 7b, 7b are provided, and the dimension between their tips is the same as the dimension between the aforementioned notches 5.5.

An enlarged portion 8 is formed adjacent to the opening 10 in a recessed manner. This enlarged portion 8 is dimensioned to allow relative rotation of the locking plate 2.

Since the bovine nose ring according to the present invention is constructed as described above, when using it, first, the engaging portion of the nose ring main body A is
When E ₂ is inserted into the opening 10 of the connector B and pushed further, the insertion portion 4b pushes open the tongue piece 7b and enters, and is attached as shown in FIG. 4. At this time, the notch 5 of the engaging portion _E1 is located where the tongues 7a, 7a are not located.

Next, insert the engaging part _E1 into the nostril N of the cow C,
By inserting the engaging portion _E1 into the opening 10 of the connector B against the elastic force of the nose ring main body A, the nose ring is attached to the cow's nose as shown in FIG. Then, in the state shown in FIG. 4, the insertion portions 4a and 4b are respectively
When inserted inside the tongues 7a, 7b, the tongues 7a, 7b elastically return to their original states, so that the conical bottoms of the insertion portions 4a, 4b snap into the tongues 7a, 7b by a so-called snap action. 7b, and
Both engaging portions E ₁ and E ₂ are connected to a connector B. In this way, the tongue pieces 7a, 7b are attached to the insertion portions 4a, 4b.
respectively engage the conical bottoms of the openings 10 and 10.
Rotation of the connecting tool B is prevented by the locking plate 2 and the locking plate 2,
Since the notch 5 does not face the tongue piece 7a, the connector B does not come off from the nose ring body A. Note that this state of engagement can be visually confirmed through the holes 12a and 12b. Further, depending on the case, marks may be provided on the outside to indicate the positions of the tongue pieces 7a, 7b. If it is desired to remove the nose ring from the cow, press the nose ring part 1 in the direction of arrow Y in FIG. Then, the inserted portions 4a, 4b both hit the intermediate wall 6 and stop. At that time, the locking plate 2
is located at the enlarged portion 8. Then, when the connector B is rotated 90 degrees around its longitudinal axis, the notch 5 of the engaging portion _E1 will be located at the tongue piece 7a. Therefore, if the pressure on the nose ring portion 1 is loosened, the connection between the engaging portion _E1 and the connector B is released.
Therefore, the nose ring can be removed from the cow's nose N.

In addition, when attaching to a cow whose nasal septum does not have a hole made, use a scissor-like attachment device (not shown) to make the hole with the conical insertion part, and simultaneously attach the coupling tool and the engaging part. It is also possible to connect with

As described above, according to the present invention, the engagement portion of the nose ring and the connector are engaged by a snap action, and when removing the nose ring, after pressing the nose ring, the connector B is centered around its longitudinal axis. Rotate the notch 5 as
Since it is only necessary to move the nose ring to the tongue piece 7a and loosen the pressure on the nose ring, engagement is ensured and removal is also easy. Moreover, unless the connector is pushed in the direction of arrow Y, the non-circular locking plate 2 will be inserted into the opening 1.
Since the connector B cannot rotate because it is engaged with the connector 0, the connector B will not rotate naturally and will not come off.
