Abstract

The present invention relates to a sealing cap that is applied to a coupling part of a supply pipe such as a gas meter or a water meter, and more particularly, to a device designed to effectively prevent an arbitrary separation operation of a meter coupled to a supply pipe.

Conventionally, if the meter connected to the supply pipe is disconnected and the direction of the meter is reversed to the supply pipe, the measuring impeller built in the meter rotates in the opposite direction. This occurred.

Therefore, the present invention is to cover the outer cover (11) to the outer side of the nut (3) to form a cylindrical cap (10) if the center of the cover 11 is placed outside the coupling nut (3) of the meter (1) When the coupler 21 is inserted through the rear side of the support tube 20 in a state in which the extended and joined pieces 12 are inserted into the support tube 20, the ratchet-shaped protrusion 21a of the coupler 21 is inserted. Is secured to the ratchet-shaped projection 12a of the extension piece 12 and is firmly fixed to prevent the separation of the cap 10. Therefore, the meter 1 may be arbitrarily separated from the supply pipe 2 to be reversely coupled.

Description

Sealing cap for gas and water meter

The present invention relates to a sealing cap that is applied to a coupling part of a supply pipe such as a gas meter or a water meter, and more particularly, to a device designed to effectively prevent an arbitrary separation operation of a meter coupled to a supply pipe.

In general, the meter is coupled to the supply pipe to measure the amount of gas or tap water used, and mainly the sealing lead is coupled to the meter so that the meter cannot be arbitrarily disassembled.

However, as described above, disassembly of the meter itself sealed by the sealing lead can be prevented, but it is possible to separate the entire meter from the supply pipe.

In other words, the meter is screwed by the nut in the supply pipe. Simply remove the meter and the meter is easily removed from the supply line.

Therefore, if the meter connected to the supply pipe is separated and then the direction of the meter is coupled to the supply pipe, the measuring impeller built in the meter rotates in the opposite direction. This occurred.

The present invention was devised in view of the above problems, and an object thereof is to provide a cap for sealing a meter coupling part which can prevent an arbitrary separation of the meter coupled to the supply pipe.

Features of the present invention for achieving the above object,

The center of the pair of semi-cylindrical covers 11 covered by the coupling nut 3 of the supply pipe 2 and the meter 1 is folded to form a cylindrical cap 10, and a ratchet type on the outside of the covers 11. Extension pieces 12 having protrusions 12a are respectively formed and inserted into the support tube 20, and the protrusions 12a of the extension pieces 12 are inserted into the support tube 20 together with the coupling holes 21. It can be achieved by a meter coupling cap sealing cap characterized in that it is fixed by the ratchet-shaped projection (21a) of.

Hereinafter, preferred embodiments of the present invention for achieving the above object attached figure When described in detail by side as follows.

As shown in Figure 1 to 5,

The cap 10 according to the present invention is formed in a cylindrical shape by folding the center of the pair of semi-cylindrical cover 11, the cylindrical cap 10 of the coupling nut 3 of the supply pipe 2 and the meter (1) It is covered on the outside.

That is, when the center of the cover 11, which is extended to both sides is folded, the semi-cylindrical covers 11 are joined to form a cylindrical cap 10, and the cylindrical cap 10 thus formed is a coupling nut 3 ) Is to be covered.

Of course, the insertion hole (11a) is formed in the center of the cylindrical cap 10 is configured to insert the pipe of the supply pipe 2 and the meter (1) coupled to both sides of the nut (3).

Extension pieces 12 are formed on the outer sides of the covers 11, and the extension pieces 12 are formed with latches 12a.

When the centers of the covers 11 are folded, the extension pieces 12 formed on both sides of the cover 11 are also joined together, and the combined extension pieces 12 are inserted into a separate support tube 20 to support the tube. It is firmly fixed by the ratchet-shaped protrusion 21a of the coupling hole 21 inserted through the rear of the 20.

Insertion hole 13a is protruded from one side of the extension piece 12 of the extension pieces 12, the through hole (13b) is formed in the other extension piece 12 is inserted when both side extension pieces 12 are combined As the 13a is fitted in the through hole 13b, the combined state of the extension pieces 12 can be held firmly.

According to the present invention having the above-described configuration, the cover 11 that is spread out on both sides is positioned outside the coupling nut 3 of the supply pipe 2 and the meter 1 and the center of the covers 11 is folded to cover the cover ( The extension pieces 12 formed at both sides of the 11 are joined to form a cylindrical cap 10 and to be covered on the outside of the nut 3.

In such a state, when the combined extension pieces 12 are inserted into the support tube 20 and the coupler 21 is inserted through the rear of the support tube 20, the ratchet-shaped protrusion 21a of the coupler 21 is provided. Is caught by the latch-shaped protrusion 12a of the extension piece 12 and is firmly fixed.

The protrusion 12a of the extension piece 12 formed in the ratchet shape can be coupled to the protrusion 21a of the coupling tool 21 made of the ratchet type by a forcible force, but in the state of being fitted once, the protrusion 12a is separated. Since the configuration is impossible, the cylindrical cap 10 covered on the outside of the coupling nut 3 is firmly fixed to prevent the separation of the cap 10.

Of course, it is possible to separate the extension piece 12 from the coupler 21 by applying artificial force, but it is inevitable that the coupler 21 and the support tube 20 are damaged during the separation operation. Naturally, it can be effectively identified and sanctioned.

Therefore, since it is possible to prevent the separation of the cylindrical cap 10 covered on the outside of the coupling nut (3), it is possible to completely prevent all problems such as randomly separating the meter (1) from the supply pipe (2) This effectively prevents the closure of valuable gas and water resources.

According to the present invention as described above, the cover 11 spreads on both sides is positioned outside the coupling nut 3 of the meter 1 and the center thereof is folded to form a cylindrical cap 10. 3) When the coupler 21 is inserted through the rear side of the support tube 20 while the extension pieces 12 covered with the outside are inserted into the support tube 20, the ratchet of the coupler 21 is latched. Since the projection 21a is caught by the ratchet projection 12a of the extension piece 12 and is firmly fixed to prevent the separation of the cap 10, the meter 1 can be detached from the supply pipe 2. On the contrary, the conventional problems such as combining are completely solved, and thus there is an advantage that the precious gas and water resources can be safely protected.
