Description

Technical Field

[0001] The utility model relates to the technical field of plastic joints, and particularly relates to a combined plastic sanitary joint. Background Art

[0002] A combined plastic sanitary joint is a quick joint for connecting plastic pipes, which usually has the characteristics of being easy to install and disassemble. As shown in the Chinese patent application with the application number 202320960137.6, the technical solution includes an external thread ring cylinder and a column cylinder. An insertion pipe is integrally formed at the axis of the external thread ring cylinder. When the column cylinder is inserted into the internal part of the external thread ring cylinder in this technical solution, the insertion pipe is inserted into the internal part of the column cylinder, and the guiding part of the insertion block is inserted into the internal part of the slot along the guiding part of the positioning block. The positioning block can play a good positioning effect on the insertion block inserted into the slot under the action of the limiting plate and the spring, thereby improving the compactness and reliability of the connection between the external thread ring cylinder and the column cylinder, and at the same time facilitating the assembly between plastic pipe joints.

[0003] However, there are still the following problems in this technical solution: The positioning block in this technical solution facilitates the assembly between plastic pipe joints under the action of the limiting plate and the spring. However, the longer the spring is used, the weaker its elasticity becomes, and finally it will not be able to support the limiting plate, resulting in the inability to assemble. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a combined plastic sanitary joint. The first joint and the second joint can be connected together through a fixing mechanism, which prolongs the service life of the utility model. A sealing mechanism can also seal the connection between the first joint and the second joint to prevent water from leaking out of the joint, so as to solve the above deficiencies in the technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A combined plastic sanitary joint includes a first joint and a second joint, and a fixing mechanism for connecting the first joint and the second joint is arranged outside the first joint.

[0006] Preferably, the fixing mechanism includes a first connecting plate arranged at one end of the first joint, a second connecting plate is fixedly arranged at one end of the second joint close to the first joint, an insertion pipe is fixedly arranged at one end of the second joint close to the first joint, a plugging slot is arranged on one side of the first joint, a plurality of connecting frames are arranged outside the first connecting plate and the second connecting plate, a plurality of second threaded holes are arranged on both the first connecting plate and the second connecting plate, a first threaded hole is arranged on the connecting frame, and the connected second threaded hole and the first threaded hole are externally threadedly connected with the same first bolt. The insertion pipe and the plugging slot are adapted to each other, and the connecting frame can be inserted outside the first connecting plate and the second connecting plate for connecting the first joint and the second joint.

[0007] Preferably, a sealing mechanism for sealing the connection between the first joint and the second joint is provided outside the first joint. The sealing mechanism includes two sealing frames arranged on both sides outside the first joint. A limiting groove is formed inside the sealing frame, and the limiting groove is adapted to the first connecting plate and the second connecting plate. Third connecting plates are fixedly arranged on both sides of the sealing frame, and a third threaded hole is formed in the third connecting plate. The same second bolt is threadedly connected inside two connected third threaded holes on the same side. A plurality of sliding grooves are formed in the sealing frame, and the sliding grooves are adapted to the connecting frame, so as to seal the connection between the first joint and the second joint.

[0008] Preferably, a limiting mechanism for limiting the first joint and the second joint is provided outside both the first joint and the second joint. The limiting mechanism includes two fourth connecting plates respectively arranged outside the first joint and the second joint. A plurality of fourth threaded holes are formed in the fourth connecting plates, and the same screw is threadedly connected inside two connected fourth threaded holes. Nuts are threadedly connected to both ends of the screw, so as to limit the first joint and the second joint.
