Description

Technical Field

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

[0002] In engineering applications, when two or more round tubes are connected to form a transmission pipeline, adjacent round tubes need to be sealed. The existing connection methods include clamping type, convex type, compression type, rolling type, welding type and pipe thread type.

[0003] The connection method of the existing compression type pipe fittings on the market is to insert a hard pipe into the socket of the compression type pipe fitting, squeeze the pipe fitting with the help of a compression tool, and clamp the hard pipe in the pipe fitting. Therefore, when the pipe fitting needs to be installed or replaced, the compression tool needs to be carried with the worker to install the pipe fitting, which increases the workload of the workers and makes the installation of the pipe fitting inconvenient. Therefore, it is of great significance to design a compression type pipe fitting. Summary of the invention

[0004] The purpose of the utility model is to provide a compression type pipe fitting in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a compression type pipe fitting, characterized in that it includes a pipe body, a mounting shell is provided at the connecting end of the pipe body, two bidirectional threaded rods are provided on the mounting shell, a bearing is provided between the bidirectional threaded rod and the mounting shell, and two extrusion plates are provided on the bidirectional threaded rod.

[0006] In the above-mentioned compression type pipe fitting, a sealing plate is arranged on the pipe body, a filter screen is fixedly arranged on the bottom of the sealing plate, and the filter screen is located inside the pipe body, and a sealing gasket is arranged between the sealing plate and the pipe body.

[0007] In the above-mentioned compression type pipe fitting, a cleaning brush is fixedly provided on the inner wall of the pipe body, and the cleaning brush is located on one side of the filter screen.

[0008] In the above-mentioned compression pipe fitting, a fixing frame is fixedly arranged on the outside of the pipe body, a connecting rod is slidably arranged on the fixing frame, a control block is fixedly arranged on the top of the connecting rod, and a fixing plate is fixedly arranged between the connecting rod and the sealing plate.

[0009] In the above-mentioned compression type pipe fitting, a spring is arranged between the fixing plate and the fixing frame, and the spring is sleeved on the outside of the connecting rod.

[0010] Compared with the prior art, the present compression type pipe fitting achieves the effect of pipe compression connection by setting an extrusion component at the pipe body connection to squeeze the pipe body, so that workers no longer need to use external tools to connect the pipe fittings, making the installation of the pipe fittings more convenient.
