Specific implementation

[0020] In order to make the utility model purposes, technical scheme and advantages more clearly, the following is connected with the drawing and example, the following will be connected with the drawing in the example of the utility model, the technical scheme in the example of the utility model embodiment is clearly and completely described, obviously, the described example is only a part of the utility model example, not all examples. Based on the example in the utility model, all other examples obtained by the ordinary skill in the art without creative labor are within the scope of the utility model protection.

[0021] As Figures 1 to 5 The embodiment provides a fire pipe connecting structure, which comprises a first fire pipe 1 and a second fire pipe 2. Between the first fire pipe 1 and the second fire pipe 2, a sealing mechanism 3 and a fixed mechanism 4 are arranged, and the two are stably connected through the sealing mechanism 3 and the fixed mechanism 4.

[0022] The sealing mechanism 3 is mainly composed of a sealing pad 301 and an annular glue storage shell 303. The sealing pad 301 is installed on the port of the first fire pipe 1, and an annular insert piece 302 is installed at the end close to the annular glue storage shell 303. The annular glue storage shell 303 is installed on the port of the second fire pipe 2, and a glue storage cavity 304 is formed in the annular glue storage shell 303. A group of glue outlet holes 305 are formed at one end of the annular glue storage shell 303, and a socket 306 is arranged between the group of glue outlet holes 305. When the annular insert piece 302 is inserted, it can enter the glue storage cavity 304 through the glue outlet hole 305, so that the sealing glue pre-filled in the glue storage cavity 304 is uniformly extruded from the group of glue outlet holes 305.

[0023] The fixing mechanism 4 comprises a fixing plate 401 and a fixing block 404. The fixing block 404 is fixedly installed on the outer surface of the first fire-fighting pipe 1, and a slot 405 is formed in the fixing block 404. The fixing plate 401 is fixedly installed on the outer surface of the second fire-fighting pipe 2, and a limiting rod 402 is fixedly installed on one end of the fixing plate 401 close to the fixing block 404. The other end of the limiting rod 402 is designed to be inserted into the slot 405 and to be in sliding connection with the inside of the slot 405. A limiting hole 403 is also formed in the limiting rod 402.

[0024] In order to further enhance the stability of the fixing, a spring 407 is also fixedly installed on the fixing block 404. A round plate 408 is fixedly installed on the other end of the spring 407 away from the fixing block 404, and a pull ring 409 is fixedly installed on the side of the round plate 408 away from the spring 407. Meanwhile, an insertion rod 406 is also fixedly installed on the side of the round plate 408 away from the pull ring 409. The other end of the insertion rod 406 is designed to be inserted into the inside of the fixing block 404 and to be in sliding connection with the inside of the fixing block 404.

[0025] In actual operation, when the limiting rod 402 is completely inserted into the slot 405, the insertion rod 406 can be inserted into the inside of the limiting hole 403 under the elastic force of the spring 407, so as to realize the limiting and fixing of the limiting rod 402.

[0026] In addition, the fixing mechanism 4 is provided with four in the embodiment, which are arranged on the outer surfaces of the first fire-fighting pipe 1 and the second fire-fighting pipe 2 to ensure the stability of the connection.

[0027] Through the above design, the fire-fighting pipe connecting structure of the embodiment not only realizes the quick and stable connection between the pipes, but also ensures the sealing of the connection through the sealing mechanism 3, so as to effectively prevent the possible leakage problem.

[0028] As Figures 1 to 5As shown, in some embodiments, the first fixation of the limiting rod 402 on the plate 401 is inserted into the slot 405 of the fixed block 404, achieving the initial limiting. In order to further reinforce this connection, when the limiting rod 402 is fully inserted into the slot 405, the round plate 408, the pull ring 409, and the insertion rod 406 originally squeezed out by the limiting rod 402 will automatically reset under the elastic force of the spring 407 and be inserted into the limiting hole 403 opened inside the limiting rod 402, thereby achieving the secondary limiting fixation of the limiting rod 402. This process ensures the stable butt joint between the first fire pipe 1 and the second fire pipe 2, providing a foundation for the subsequent sealing work. At the same time, the sealing mechanism 3 begins to play a role, ensuring the sealing of the connection. The sealing pad 301 is installed at the port of the first fire pipe 1, and the annular glue storage shell 303 is installed at the port of the second fire pipe 2. When the two fire pipes are butt jointed, the annular insertion piece 302 will pass through the insertion opening 306 on the annular glue storage shell 303 and be inserted into the glue storage cavity 304 through a group of glue outlet holes 305. With the insertion of the annular insertion piece 302, the sealing glue pre-filled in the glue storage cavity 304 will be uniformly squeezed out and filled into the connection gap between the two fire pipes through the glue outlet holes 305, forming a layer of tight sealing layer.

[0029] Working principle: when the fire pipe connecting structure of the utility model is used, first, the first fire pipe 1 and the second fire pipe 2 are butt jointed. In the butt joint process, the fixing mechanism 4 plays the role of preliminary fixing, ensuring the stable connection of the two fire pipes. Specifically, the limiting rod 402 on the fixed plate 401 will be inserted into the slot 405 of the fixed block 404, realizing preliminary limiting. In order to further reinforce the connection, when the limiting rod 402 is completely inserted into the slot 405, the round plate 408, the pull ring 409 and the insertion rod 406 originally squeezed out by the limiting rod 402 will be automatically reset under the elastic force of the spring 407 and inserted into the limiting hole 403 opened in the limiting rod 402, thereby realizing secondary limiting and fixing of the limiting rod 402. This process ensures the stable butt joint between the first fire pipe 1 and the second fire pipe 2, providing a basis for subsequent sealing work. At the same time, the sealing mechanism 3 starts to play a role, ensuring the sealing property of the connection. The sealing gasket 301 is installed at the port of the first fire pipe 1, and the annular glue storage shell 303 is installed at the port of the second fire pipe 2. When the two fire pipes are butt jointed, the annular insertion piece 302 will pass through the insertion opening 306 on the annular glue storage shell 303 and be inserted into the glue storage cavity 304 through a group of glue outlet holes 305. With the insertion of the annular insertion piece 302, the sealing glue pre-filled in the glue storage cavity 304 will be uniformly squeezed out and filled into the connection gap of the two fire pipes through the glue outlet hole 305, forming a layer of tight sealing layer. In this way, not only the sealing property of the connection is ensured, but also the leakage problem caused by factors such as vibration or temperature change is effectively prevented. Through the synergistic effect of the above fixing mechanism 4 and sealing mechanism 3, the fire pipe connecting structure of the utility model realizes stable and sealed connection effect. This connection mode not only greatly improves the convenience of assembly, but also significantly enhances the stability and sealing property of the connection, thereby effectively solving the problems of the traditional fire pipe connecting mode in the sealing performance and assembly efficiency.
