DETAILED DESCRIPTION

[0019] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0020] Please refer to Figs. 1-3 In the embodiments of the present application, the gas pipe fixing clamp comprises an expansion bolt assembly 1 composed of a T-shaped stud 101, an expansion sleeve 102, a gasket 103 and a fastening nut 104, and two clamps 2, the expansion sleeve 102, the gasket 103 and the fastening nut 104 are sequentially sleeved on the outer side of the T-shaped stud 101, and the fastening nut 104 is threadedly connected to the T-shaped stud 101, one clamp 2 has a butt joint column 3 fixed on the outer side, and the T-shaped stud 101 has an insertion hole slot 105 extending into the T-shaped stud 101 at one end, and the butt joint column 3 is inserted into the inner side of the insertion hole slot 105 to realize the butt joint operation of the clamp 2 and the expansion bolt assembly 1.

[0021] The outer side of the butt joint column 3 is provided with a locking and adjusting assembly 4, which is used to realize the connection and fixation of the butt joint column 3 and the T-shaped stud 101, and simultaneously realize the depth adjustment of the insertion of the butt joint column 3 into the insertion hole slot 105, so as to realize the alignment operation of the plurality of clamps 2.

[0022] The locking and adjusting assembly 4 comprises an annular clamping groove 401, a connecting screw sleeve 402 and a clamping spring plate 403.

[0023] The annular clamping groove 401 is uniformly provided along the long side direction of the butt joint column 3, and the connecting screw sleeve 402 is slidably sleeved on the outer side of the butt joint column 3.

[0024] The clamping spring plate 403 is fixed to the inner side top of the connecting screw sleeve 402, and the arc protrusion of the clamping spring plate 403 is clamped in the inner side of the annular clamping groove 401, which is used to realize the position limiting of the connecting screw sleeve 402 and the butt joint column 3, and the outer side of the connecting screw sleeve 402 which is threadedly connected to the T-shaped stud 101 protrudes from the outer part of the wall surface to realize the connection and fixation of the butt joint column 3 and the T-shaped stud 101.

[0025] In the present embodiment, the operation steps of installing and using the gas pipe fixing clamp are as follows:

[0026] First, according to the installation route of the gas pipe, the expansion bolt installation hole is set in the corresponding position, and then the expansion bolt assembly 1 is installed in the installation hole (it should be noted that the installation and fixation of the expansion bolt assembly 1 is the same as the traditional expansion bolt installation operation, which will not be described in detail here).

[0027] After that, the clamp 2 can be connected with the T-shaped stud 101, at this time, only need to insert the butt joint column 3 into the insertion hole slot 105 inside until the connecting sleeve 402 contacts with the T-shaped stud 101, then rotate the connecting sleeve 402, make the connecting sleeve 402 and the T-shaped stud 101 screw connection, that is, the connection of the clamp 2 and the T-shaped stud 101 is completed;

[0028] In this process, due to the unevenness of the wall surface or the change of the hole diameter, the length of the T-shaped stud 101 protruding from the wall surface is different, which will make the installed multiple clamps 2 not on the same horizontal line, therefore, when installing the clamp 2, the relative position of the connecting sleeve 402 and the butt joint column 3 can be adjusted:

[0029] By pulling the connecting sleeve 402 to move along the outer wall of the butt joint column 3, at this time, when the clamping spring 403 is separated from one annular clamping groove 401, it will be extruded by the butt joint column 3 and deformed, when the clamping spring 403 is aligned with another annular clamping groove 401, it will reset and clamp with the annular clamping groove 401 under the action of its own elastic force (it should be noted that the clamping spring 403 is in the shape of inverted "Ω"), so the mutual positioning of the connecting sleeve 402 and the butt joint column 3 is realized, after adjusting the position of the connecting sleeve 402, the butt joint column 3 is inserted into the insertion hole slot 105, the depth adjustment of the insertion of the butt joint column 3 into the insertion hole slot 105 is realized, thereby the position adjustment of the clamp 2 is realized, so that the position of the clamp 2 matches the distribution path of the gas pipe.

[0030] Please refer to Figs. 2-3 , the bottom edge of the clamping spring 403 is formed with a fan-shaped bottom piece 404, which is used to realize the reinforcement of the clamping state of the clamping spring 403 and the annular clamping groove 401 by being attached to the end face of the T-shaped stud 101;

[0031] The clamping spring 403 is arranged in a plurality of annular shapes with the center line of the connecting sleeve 402 as the center, and the outer diameter of the fan-shaped bottom piece 404 is smaller than the inner diameter of the connecting sleeve 402.

[0032] In this embodiment, when the connecting sleeve 402 is screwed with the T-shaped stud 101, the fan-shaped bottom piece 404 is closely attached to the end face of the T-shaped stud 101, at this time, the clamping spring 403 is extruded by the T-shaped stud 101 and the connecting sleeve 402, so that the clamping spring 403 cannot be deformed, thereby ensuring the stability of the clamping state of the clamping spring 403 and the annular clamping groove 401;

[0033] In addition, by arranging the structure that the outer diameter of the fan-shaped bottom piece 404 is smaller than the inner diameter of the connecting sleeve 402, the fan-shaped bottom piece 404 will not block the deformation of the clamping spring 403 during the position adjustment of the connecting sleeve 402.

[0034] Please pay attention to Fig. 1 The inner diameter of the insertion hole slot 105 matches the outer diameter of the butt joint column 3, and the depth of the insertion hole slot 105 is greater than the length of the long side of the butt joint column 3.

[0035] In this embodiment: through this structure, the butt joint column 3 can be completely inserted into the insertion hole slot 105, and the butt joint column 3 and the insertion hole slot 105 do not shake when they are sleeved with each other.

[0036] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art within the technical range disclosed by the present application, according to the technical scheme and the utility model concept of the present application, equivalent replacement or change, should be covered within the protection scope of the present application.
