Description

Technical Field

[0001] The utility model relates to the technical field of grooved pipe fittings, in particular to a grooved pipe fitting. Background Art

[0002] Grooved pipe fittings are special fittings used in piping systems. They are mainly used to connect, support and adjust pipes in grooved piping systems. They are commonly used in places such as commercial buildings, industrial facilities and fire protection systems.

[0003] The Chinese patent with the existing authorization announcement number CN220204970U discloses a grooved pipe fitting that is easy to connect. The connection mechanism provided by the invention contains a plurality of clamps, a connecting hook and a sleeve, which reduces the number of bolts and nuts that need to be installed when fixing and disassembling the grooved pipe fitting, simplifies the installation and disassembly operations, and makes the grooved pipe fitting easy to connect and disassemble. However, the groove sleeve is a connection device on the pipeline, which is usually made of metal and is used to connect and fix the grooved pipe fitting. A rubber gasket is usually provided in the groove sleeve to provide sealing performance and prevent liquid or gas leakage. However, during the landfill process, external force may cause the connection between the groove sleeve and the pipeline to loosen, causing the connection between the sealing ring and the pipeline to be separated, which may easily affect the pipeline sealing. Moreover, the groove sleeve is only fixed by converging the connection. When subjected to external impact, it is easy to be offset and deformed, affecting the normal use of the device.

[0004] In summary, the current grooved pipe fittings still have the following defects during installation and use at the user end:

[0005] (1) During the landfill process, external force may cause the connection between the groove sleeve and the pipeline to loosen, causing the connection between the sealing ring and the pipeline to separate, which may easily affect the pipeline seal;

[0006] (2) The groove sleeve is only fixed by the convergence connection, and it is easy to deviate and deform when subjected to external impact, affecting the normal use of the device; Utility Model Content

[0007] In order to overcome the above-mentioned defects of the prior art, the inventors conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0008] Specifically, the technical problem to be solved by the utility model is to provide a groove pipe fitting to solve the problem that in the current groove pipe fittings, during the landfill process, external force will cause the connection between the groove sleeve and the pipeline to loosen, causing the connection between the sealing ring and the pipeline to be detached, which is likely to affect the pipeline seal, and the groove sleeve is only fixed by the convergence connection. When subjected to external impact, it is easy to be offset and deformed, affecting the normal use of the device.

[0009] In order to solve the above technical problems, the technical solution of the utility model is:

[0010] A groove pipe fitting, comprising a main pipe body and a sub-pipe body, wherein an assembly mechanism is provided at the connection between the main pipe body and the sub-pipe body, wherein the assembly mechanism comprises a sealing member, wherein the sealing member comprises a guide frame, wherein a positioning block is movably connected to the bottom of the guide frame, wherein an elastic gasket is provided at the bottom of the positioning block, and wherein the elastic gasket is located at the connection between the main pipe body and the sub-pipe body;

[0011] A guide shaft is fixedly installed on the top of the positioning block, and the guide shaft runs through the entire guide frame. The guide frame is provided with a spring on the outside of the guide shaft;

[0012] A guide sliding block is also fixedly mounted on the outer side of the guide shaft, and the guide sliding block is located at the bottom of the spring.

[0013] A first bolt is arranged on the top of the guide sliding block, one end of the first bolt protrudes from the top of the guide frame and is threadedly connected with the guide frame.

[0014] The sealing member further comprises an outer sleeve, which is arranged at the bottom of the guide frame. A positioning opening is formed on the outer side of the outer sleeve, and the positioning opening is adapted to the positioning block.

[0015] The assembly mechanism also includes a docking piece, which includes a docking sleeve. A sealing groove is provided on the inner side of the docking sleeve. The elastic gasket is installed on the inner side of the docking sleeve through the sealing groove. Deformation holes distributed in a circular array are also provided on the inner side of the sealing groove. A limiting sliding groove is also provided on the inner side of the docking sleeve.

[0016] The docking member further comprises a first joint, which is fixedly mounted on one end of the main pipe body close to the elastic gasket, and the main pipe body is connected to the docking sleeve via the first joint.

[0017] The docking piece also includes a second joint, which is fixedly mounted on one end of the auxiliary tube body close to the elastic gasket. The outer side of the second joint is also threadedly connected to an inner sleeve, and the second joint is threadedly connected to the outer sleeve through the inner sleeve.

[0018] A constricting member is also provided at the connection between the main pipe body and the auxiliary pipe body. The constricting member includes a groove sleeve body. The guide frame is fixedly installed on the outside of the groove sleeve body. The second bolt and the third bolt are respectively installed at both ends of the groove sleeve body.

[0019] After adopting the above technical solution, the beneficial effects of the utility model are:

[0020] (1) When the grooved pipe fitting is in use, the positioning block is pushed by the guide shaft under the restriction of the positioning opening in the outer sleeve, thereby squeezing the elastic gasket, causing the elastic gasket to deform. The deformed elastic gasket fills the deformation hole in the sealing groove, thereby making it difficult for the elastic gasket to detach from the connection between the main pipe body and the auxiliary pipe body.
