In the drawings, the dimensions of some features can be distorted for the sake of clarity. The language used in the specification is only used to describe specific embodiments and is not intended to limit the present application. All terms (including technical terms and scientific terms) used in the specification have meanings commonly understood by those skilled in the art unless otherwise defined. For the sake of brevity and / or clarity, well-known functions or structures can not be described in detail.

[0020] An embodiment of the present application provides a gas anti-disassembly lock card, please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2The structure of the anti-disassembly lock card is shown from different angles. The anti-disassembly lock card is composed of two lock bodies 100. The lock body 100 includes a shell 10, a lock end 20, and a slot end 30. The two ends of the shell 10 are respectively the lock end 20 and the slot end 30. The lock end 20 of one lock body 100 is inserted into the slot end 30 of the other lock body 100, and the two lock bodies 100 form an interlocking structure.

[0021] The anti-disassembly lock card is installed outside the nut at the outlet of the gas meter and the pipeline connection. The surface of the lock card is provided with a two-dimensional code for identity recognition. Through the physical locking structure of the lock card and the identity verification of the two-dimensional code, unauthorized private disassembly of the gas equipment by the user can be effectively prevented.

[0022] The shell 10 is a semi-arc thin-walled structure. The upper and lower end faces are provided with a guard plate 11 extending to the center of the arc face. The width of the guard plate 11 is 10 mm. The guard plate 11 is used to cover the upper end face or the lower end face of the nut.

[0023] Specifically, the buckle 21 on the lock end 20 is matched with the slot 31 on the slot end 30. The inner wall of the slot 31 is provided with a retractable thimble 32 facing the center of the shell 10. The end surface of the buckle 21 is arranged away from the thimble 32, and the notch on the buckle 21 is matched with the thimble 32. When buckled, the buckle 21 can only be inserted in one direction and cannot be pulled out in reverse.

[0024] Please refer to Figure 3 , Figure 3 The sectional view of the anti-disassembly lock card is shown. The lock end 20 is block-shaped. The connection between the lock end 20 and the outer surface of the shell 10 is provided with a disassembly opening 22 with a width of 1-3 mm. After the two lock bodies 100 are buckled, a gap 35 is left between the surface where the buckle 21 and the thimble 32 of the slot 31 are located, which facilitates the use of a screwdriver or a pry bar by the maintenance personnel to pry the connection between the lock end 20 and the shell 10. This way, the operation can be performed without the use of hydraulic pliers in a small space, reducing the difficulty of the operation. At the same time, since the surface of the lock card is provided with an identity recognition code, even if the user disassembles and replaces it by himself, the maintenance personnel can easily identify it.

[0025] Please refer to Figure 4 , Figure 4 The local structure after the lock end 20 and the slot end 30 are buckled is shown. The thimble 32 slides in the hole slot in the side wall of the lock end 20. The hole slot is provided with a spring 33. The outer end of the hole slot is sealed with aluminum solder. After sealing, it is polished smooth. One end of the spring 33 is against the filler 34, and the other end is against the end of the thimble 32, which is in a compressed state. The diameter of the front end of the thimble 32 is smaller than that of the end. The opening at the inner end of the hole slot is matched with the front end of the thimble 32.

[0026] In use, the two lock bodies 100 are buckled outside the nut at the outlet of the gas meter and the pipeline connection to prevent users from disassembling privately; the lock surface is provided with a two-dimensional code for identity recognition, further preventing unauthorized disassembly or replacement.

[0027] Since the gas meter is usually installed in a small space, it is difficult to use hydraulic pliers to cut the lock card; using the lock card provided by the application, the maintenance worker only needs to insert the screwdriver into the disassembly opening 22 to pry off the connection between the lock end 20 and the shell 10 to disassemble the lock card; after completing the maintenance or replacing the gas meter, a new lock card is installed and the identity recognition code is entered.

[0028] Although exemplary embodiments of the present application have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of the present application without departing from the spirit and scope of the present application in essence. Therefore, all changes and modifications are included in the protection scope of the present application defined by the claims. The present application is defined by the appended claims, and the equivalents of these claims are also included.
