Description

Technical Field

[0001] The utility model relates to a gas meter protection device, in particular to a gas meter gas inlet and outlet protection device. Background Art

[0002] When installing civil natural gas pipelines in residents' homes, it is necessary to first connect the gas meter to the pipeline. Some lawless elements will illegally modify the gas meter, and there is a phenomenon of stealing gas from the air inlet pipe. At present, the existing devices in residents' homes do not have a structure to protect and prevent disassembly of the air inlet and outlet pipes connected to the gas meter when in use. The air inlet and outlet pipes of the gas meter are softer than other pipes when in use, making the air inlet and outlet pipes very easy to be damaged when they are bumped or hit by sharp objects. In addition, since the air inlet and outlet pipes contain natural gas after installation and use, it is too dangerous to disassemble them without authorization. In order to prevent gas theft, the air inlet and outlet need to be protected. The utility model designs a gas meter air inlet and outlet protection device. Summary of the invention

[0003] In order to solve the above problems existing in the prior art, the utility model provides a gas meter air inlet and outlet protection device, which has the characteristics of preventing disassembly and protecting the air inlet and outlet connected to the gas meter.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A gas meter inlet and outlet protection device comprises two semicircular clamps and a lead seal for locking the clamps; wing plates are respectively provided on both sides of the clamps, and a limiting hole is provided on one wing plate of the clamps, and a limiting tube is provided on the other wing plate, the two clamps are opposite to each other, and the limiting tube of one clamp is matched with the limiting hole on the other clamp; the lead seal comprises a first lead seal body and a second lead seal body, the second lead seal body passes through the limiting tubes on the two clamps in turn and then penetrates into the first lead seal body to lock and fix the two clamps.

[0006] Furthermore, it also includes a cold shrink tube for protecting the air inlet pipe and the air outlet pipe of the gas meter, and the cold shrink tube is sleeved on the air inlet pipe and the air outlet pipe of the gas meter.

[0007] Furthermore, a rubber cushion layer is provided on the inner side of the clamp.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] 1. The device is convenient for locking and protecting the gas inlet and outlet of the gas meter, preventing users from privately disassembling and modifying the gas, and improving the safety protection measures of the gas meter;

[0010] 2. When the utility model is in use, the cold shrink tube is arranged so that the cold shrink tube is closely attached to the outer wall of the connecting pipe, thereby preventing the connecting pipe from leaking after being bumped, thereby avoiding dangerous accidents caused by gas leakage.

[0014] In the figure, 1-gas meter, 101-gas meter air inlet and outlet, 201-hoop, 202-wing plate, 203-limiting hole, 204-limiting tube, 205-lead seal, 2051-first lead seal body, 2052-second lead seal body, 3-gas meter air inlet and outlet pipes, 301-connecting sleeve, 302-gas meter air inlet and outlet pipes, 303-cold shrink tube. DETAILED DESCRIPTION

[0015] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0016] like Figure 1-3 As shown, a gas meter inlet and outlet protection device includes an anti-disassembly structure for clamping the inlet and outlet of the gas meter, the anti-disassembly structure includes two semicircular clamps 201, and a lead seal 205 for locking the clamps 201; a rubber pad is provided on the inner side of the clamp 201, and when the clamp 201 is locked, the rubber pad can be pressed against the inlet and outlet to achieve a good anti-leakage effect. Wing plates 202 are provided on both sides of the clamp 201, and a limiting hole 203 is provided on the wing plate 202 on one side of the clamp 201, and a limiting tube 204 is provided on the wing plate 202 on the other side. The two clamps 201 are opposite to each other, and the limiting tube 204 of one clamp 201 is matched with the limiting hole 203 on the other clamp 201, so as to prevent the two clamps 201 from moving and affecting the effect of the anti-disassembly mechanism. The lead seal 205 includes a first lead seal body 2051 and a second lead seal body 2052. The second lead seal body 2052 passes through the limiting tubes 204 on the two clamps 201 in sequence and then penetrates into the first lead seal body 2051 to lock and fix the two clamps 201, so that the two clamps 201 fit tightly, achieving a good effect of preventing air leakage and disassembly. The lead seal 205 adopts an existing lead seal product, which has the characteristic that it cannot be opened once fixed.

[0017] The utility model also includes a cold shrink tube 303 for protecting the air inlet pipe and the air outlet pipe of the gas meter. The cold shrink tube 303 is sleeved on the air inlet pipe and the air outlet pipe of the gas meter. When the air inlet pipe and the air outlet pipe of the gas meter collide and the pipe is damaged, the cold shrink tube 303 will be tightly wrapped and pressed on the air inlet pipe and the air outlet pipe of the gas meter due to its shrinkage property, thereby preventing the air inlet pipe and the air outlet pipe of the gas meter from leaking and causing dangerous accidents.
