Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a heat insulating cover for the purpose of preventing water meters from freezing and breaking.

(Prior art) Conventionally, as a heat-insulating cover for a water meter, the heat-insulating cover for a water meter described in Japanese Patent Publication No. 56-19419 is known, and the opening/closing lid plug is of a removable structure. It was hot.

(Problem to be Solved by the Invention) However, in the case of conventional water meter thermal covers, the opening/closing lid plug has a removable structure, so it cannot be used for water meters installed in places where piping such as gas pipes are crowded. When the cap was set, there was a problem in that the cap could not be opened and closed as expected, causing a great deal of trouble in meter reading work.

The present invention was developed in view of the above-mentioned drawbacks of the conventional heat-insulating cover for water meters, and its purpose is to enable smooth opening and closing of the lid even in narrow spaces with existing gas piping, etc., and to save space. To provide a heat insulating cover for a water meter that can be used without any work.

(Means for Solving the Problems) As a means for achieving the above-mentioned object, the heat insulation cover for a water meter of the present invention includes a pair of left and right mating molds 1 and 2 having a storage section 3 in which a water meter M is stored; Opening/closing lids 4, 4 that are slidable in the circumferential direction are attached to recesses 1a, 2a formed on the upper parts of the mating molds 1, 2, and the opening/closing lids 4, 4 are slidable while the mating molds 1, 2 are fixed. It is a heat insulating cover consisting of belt-shaped fastening members 6, 6 that serve as guides when the mating molds 1, 2 are used. recesses 1a, 2a for mounting the opening/closing lids 4, 4 are provided between the two band-shaped grooves 1c, 1c, and an opening S is formed in the recesses 1a, 2a; , there are two double-opening lids 4, 4 that are slidable in the circumferential direction and open and close the opening S.
At the same time, notches 4c, 4c are formed at both ends of the opening/closing lids 4, 4, so that the opening/closing lids 4, 4 are substantially flush with the band grooves 1c, 1c when installed in the recesses 1a, 2a,
Further, the fastening members 6, 6 are connected to the two band-shaped grooves 1.
A configuration is adopted in which the opening/closing lids 4, 4 are wrapped over the notches 4c, 4c within the opening/closing lids 4, 1c.

(Function) Therefore, when attaching the heat-insulating cover for a water meter of the present invention to a water meter, first fit the mating type storage part into the water meter, fit the opening/closing lid into the mating type recess, and then tighten it. Attach the parts to both sides of the mold and set.

(Example) Next, an example of the present invention will be described in detail based on the drawings.

As shown in the drawing, the combined molds 1 and 2 have a storage part 3 in which the water meter M is stored, and the outer surfaces are each formed in a circular arc, and an opening is provided at the top when the combined molds 1 and 2 are combined. It is formed with an opening S and a substantially horizontal cylindrical shape. In addition, a is a mating surface. The mating mold 1 is fitted from the back side of the piped water meter M, and the mating mold 2 is fitted from the front side to fix the faces. Concave portions 1a and 2a are formed to be opened and closed by sliding.

Moreover, semicircular notches 1b and 2b are formed at both ends of the mating molds 1 and 2 to form a pipe insertion hole 5. a fastening member 6 for fixing the mating molds 1 and 2;
Belt-shaped grooves 1c, 1c are formed in the tightening portion 6.

Next, the opening/closing lids 4, 4 are slid on the outer peripheral surfaces of the mating molds 1, 2 by approximately half a circumference.
recesses 1b, 2b and inner surfaces 4a, 4 of opening/closing lids 4, 4
a with the same curvature, and the facing surfaces are formed in a stepped shape with the joint surface 4b, and both opening/closing lids 4, 4 are integrally brought into close contact with each other with this joint surface 4b, and the mating mold 1, The opening S of No. 2 is configured to be sealed. In addition, the outer peripheral surface of the opening/closing lids 4, 4 has a plurality of finger grooves 4 on which the fingertips of the hands can hang.
d, 4d... are formed. In addition, since the fastening members 6, 6 also serve as guide plates, the lids 4, 4
Notches 4c, 4c are provided at both left and right ends of the lid 4 to facilitate rotation of the lid 4, and to prevent the opening/closing lids 4, 4 from detaching from the mating molds 1, 2. The materials for the above mating molds 1 and 2 and the opening/closing lid 4 are as follows:
In addition to thermoplastic resins such as polyurethane resins, polyethylene resins, and polystyrene resins, polyethylene foam beads, polystyrene foam beads, or polymer foam beads molded by vacuum forming or in-mold molding, and thermosetting. It can be used as appropriate, such as one made by foam molding a plastic resin.

Next, the fastening members 6, 6 are made of thin strips such as cloth, sheet plates, stainless steel plates, etc., and are inserted into the strip grooves 1d, 1d provided in the circumferential direction of the mating molds 1, 2. are fitted to fasten and fix the overlapping portions of both ends of the fastening members 6, 6.

Therefore, when attaching the heat insulating cover of the present invention to a water meter M, the storage parts 3 of the mating molds 1 and 2 are fitted into the water meter M, and the opening/closing lids 4, 4 are fitted into the recesses 1b, 2b of the mating molds 1, 2. After fitting, the fastening members 6, 6 are attached to both sides of the mating molds 1, 2 and set.

(Effects of the Invention) As described above, the heat insulation cover of the water meter of the present invention is opened and closed by sliding the double-opening lids 4, 4 in both left and right directions using the fastening members 6, 6 of the mating molds 1, 2 as guides. Even in situations where other piping such as gas is installed directly above the water meter and the cover cannot be opened or closed, the cover can be opened and closed easily, making meter reading work easier. The effect is that it can be done very easily.

Further, in the present invention, since the opening/closing lids 4, 4 are formed in a double-opening type, when reading the water meter, reading the water meter can be carried out by simply sliding one opening/closing lid 4 approximately a quarter of the way around. This has the effect of allowing meter reading work to be carried out in a short period of time.
