Description

Technical Field

[0001] The utility model relates to the field of seals, in particular to a new type of metal gas meter seal. Background Art

[0002] The gas meter seal usually refers to the seal or fastener used to seal the gas meter. These seals are usually made of special materials and have anti-counterfeiting and anti-tampering functions, which can ensure the normal operation of the gas meter and prevent unauthorized access. When installing and maintaining the gas meter, it is very important to ensure that the seal is intact to ensure the safe use of gas.

[0003] After retrieval, the Chinese patent publication number: CN217304053U discloses a new type of metal gas meter seal, which relates to the field of disposable seals; it includes a right buckle body and a left buckle body. A front retaining ring is fixed at the front end of the right buckle body, a rear retaining ring is fixed behind the right buckle body, a lock plate fixing block is fixed below the right buckle body, a lock plate is fixed in the middle on the right side of the lock plate fixing block, a stopper is arranged on the lower right side of the lock plate, an insertion plate is fixed above the right buckle body, a front retaining ring is fixed at the front end of the left buckle body, a rear retaining ring is fixed behind the left buckle body, a lock groove plate is fixed below the left buckle body, a lock groove is arranged above the lock groove plate, a spring stopper is arranged below the lock groove, an insertion plate stopper is fixed above the left buckle body, and an insertion plate groove is arranged below the insertion plate stopper. The left buckle body and the right buckle body cooperate with each other. The insertion plate is inserted into the insertion plate groove, and the lock plate is inserted into the lock groove. The gas meter can be locked without other auxiliary devices, and the operation is convenient and simple.

[0004] The above-mentioned seal is made of metal material, and the metal material has a greater hardness compared to materials such as plastic, which results in low deformation ability. Moreover, the structure of the insertion plate and the insertion plate stopper, as well as the lock plate and the lock groove plate in this seal, makes it impossible to directly align and fasten the two buckle bodies together. It can only insert the insertion plate into the insertion plate groove first, and then insert the lock plate into the lock groove. However, this causes a certain angle between the two buckle bodies when the lock plate is inserted into the lock groove, and the lock plate can only be inserted obliquely into the lock groove. This requires a certain space to be left between the lock groove and the lock plate for the insertion plate to be inserted. However, the space will cause the connection between the two buckle bodies to become loose, affecting the safety of the seal. If no space is left, it will cause difficulty in inserting the lock plate into the lock groove, making it less practical. Therefore, a new type of metal gas meter seal is proposed to solve the above problems. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a new type of metal gas meter seal, aiming to improve the problem that in the prior art, a certain space needs to be left between the lock groove and the lock plate for the insertion plate to be inserted, but the space will cause the connection between the two buckle bodies to become loose, affecting the safety and firmness of the seal.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1, an embodiment provided by the present utility model: a new type of metal gas meter seal, including a first buckle body 1, a second buckle body 2 is arranged on the right side of the first buckle body 1, the first buckle body 1 and the second buckle body 2 form a seal ring, and limiting half rings 5 are fixedly connected to the tops of the first buckle body 1 and the second buckle body 2 for fixing pipelines. First connecting plates 3 are fixedly connected to the front and rear sides of the first buckle body 1, and second connecting plates 4 are fixedly connected to the front and rear sides of the second buckle body 2. The first connecting plates 3 and the second connecting plates 4 are used to cooperate with the fixation between the first buckle body 1 and the second buckle body 2.

[0032] As Figure 2 - Figure 4 shown, a limiting plate 31 is fixedly connected to the right side of the first connecting plate 3 for cooperating with a fixing member for the fixation between the first connecting plate 3 and the second connecting plate 4. A first inclined surface 311 is arranged on the right side of the limiting plate 31, which is adapted to the second inclined surface 431. A card slot 32 is formed in the middle of the limiting plate 31 for cooperating with the fixation of a clamping plate 43. A first inclined slot 321 is formed in the lower right side of the card slot 32 for assisting the clamping plate 43 to be inserted into the card slot 32.

[0033] Furthermore, a connecting slot 41 is formed in the middle of the left side of the second connecting plate 4 for cooperating with the connection of the limiting plate 31, and the limiting plate 31 is movably connected thereto. An installation slot 42 is formed in the middle of the side of the connecting slot 41 away from the limiting plate 31 for cooperating with the installation of a fixing member. A fixing member is arranged in the middle of the installation slot 42 for fixing the limiting plate 31, so as to fix the first buckle body 1 and the second buckle body 2. The fixing member includes a clamping plate 43, which cooperates with the limiting plate 31, and one side of which is located in the installation slot 42, so as to fix the first connecting plate 3 and the second connecting plate 4. A second inclined surface 431 is arranged on the side of the clamping plate 43 close to the limiting plate 31, which is adapted to the first inclined surface 311, facilitating the limiting plate 31 to push the clamping plate 43. A connecting rod 44 is penetrated and rotatably connected to the side of the clamping plate 43 close to the second buckle body 2 for cooperating with the installation of the clamping plate 43. The upper and lower ends of the connecting rod 44 penetrate through the installation slot 42 and are movably connected thereto. A torsion spring 45 is arranged on the outside of the connecting rod 44 for cooperating with the angular change of the clamping plate 43, and at the same time assisting the clamping plate 43 to be inserted into the card slot 32. One end of the torsion spring 45 is fixedly connected to the clamping plate 43, and the other end of the torsion spring 45 is fixedly connected to the right side of the installation slot 42 for cooperating with the operation of the clamping plate 43. A second inclined slot 421 is formed in the right part of the side of the installation slot 42 close to the limiting plate 31 for cooperating with the angular change of the clamping plate 43.

[0034] Working principle: When in use, align the first buckle body 1 with the second buckle body 2, as well as the first connecting plate 3 and the second connecting plate 4, align the limiting plate 31 with the connecting groove 41, then press the first buckle body 1 towards the second buckle body 2, make the first connecting plate 3 close to the second connecting plate 4, and push the limiting plate 31 into the connecting groove 41. When the limiting plate 31 moves into the connecting groove 41, the first inclined surface 311 will gradually approach the second inclined surface 431, and the limiting plate 31 will push the clamping plate 43 accordingly. The clamping plate 43 will tilt at an angle to the right accordingly. As the limiting plate 31 continues to move to the right, when the clamping plate 43 contacts the first inclined groove 321, with the continuous movement of the limiting plate 31, the clamping plate 43 will gradually reset along the shape of the first inclined groove 321, and thus snap into the clamping groove 32, so that the clamping plate 43 fixes the limiting plate 31, thereby fixing the first connecting plate 3 and the second connecting plate 4, and fixing the first buckle body 1 and the second buckle body 2. Since one side of the clamping plate 43 is located in the installation groove 42, when it is desired to separate the first buckle body 1 and the second buckle body 2, the limiting plate 31 will pull the clamping plate 43 through the clamping groove 32, and the inner wall of the installation groove 42 will limit the position of the clamping plate 43 to fix the clamping plate 43, so that the first buckle body 1 and the second buckle body 2 cannot be opened.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
