Description

Technical Field

[0001] The utility model belongs to the technical field of gas meters, and particularly relates to a protective box for a gas meter. Background Art

[0002] Household gas meters are generally installed in the kitchen. Since the kitchen is relatively narrow, the gas meter is usually installed by connecting the gas inlet and outlet pipes of the gas meter to the gas pipeline and then hanging it. It lacks protection and is easily damaged when it is hit.

[0003] Prior art, such as Chinese patent CN219694266U, discloses a gas meter protection box that can protect the gas meter. However, in this technology, the circular holes provided on the protection box for the gas meter's inlet and outlet pipes fit together with the inlet and outlet pipes. While this protects the gas meter in the event of a collision, the inlet and outlet pipes are tightly connected to the protection box, subjecting them to collision forces. This can easily cause the inlet and outlet pipes to become loosely connected to the gas pipeline, leading to gas leaks.

[0004] Therefore, it is necessary to propose a protective box for a gas meter to solve the above problems. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a protective box for a gas meter, which is used to solve the problem that the protective box in the prior art cannot protect the air inlet pipe and the air outlet pipe of the gas meter, resulting in poor protection effect.

[0008] Furthermore, a plurality of threaded grooves arranged around the through hole are circumferentially arranged in the mounting groove in the axial direction of the mounting groove, a fixing ring is installed in the mounting groove, the fixing ring is provided with connecting holes that match the threaded grooves one by one, and the elastic gasket is provided with through holes that match the threaded grooves one by one, and the fixing ring is threadedly fixed to the threaded groove by bolts passing through the connecting holes and the through holes in sequence, so that the elastic gasket is fixedly installed between the fixing ring and the top wall of the mounting groove.

[0009] Furthermore, a first protective ring is provided on the elastic gasket, which is fixedly connected to the elastic gasket as a whole. The outer wall of the first protective ring abuts against the inner wall of the through hole. The top surface of the first protective ring and the top surface of the fixed ring are located in the same plane, and the bottom surface of the first protective ring and the plane where the bottom end of the through hole is located are located in the same plane.

[0010] Furthermore, a second protective ring is provided on the elastic gasket and is fixedly connected to the elastic gasket as a whole.
