Description

Technical Field

[0001] The utility model relates to the technical field of pipe joints, in particular to a pipe joint assembly. Background Art

[0002] Pipe fittings are sealed pipe fittings suitable for non-corrosive or corrosive media such as oil, water, and gas. The specifications of aluminum-plastic pipes are relatively flexible. After being connected to the pipeline, they have the characteristics of reliable connection and good sealing performance. Therefore, they are widely used in oil refining, chemical industry, light industry, textile, metallurgy, aviation, shipbuilding and other systems. They are also suitable for hydraulic transmission pipelines such as various mechanical engineering and machine tool equipment.

[0003] Although the existing pipe joint group can connect the pipeline through the thread and the nut, and fill the sealing glue on the ferrule after the connection to increase the sealing, the sealing glue will fall off with the increase of the use time, causing the fallen sealing glue to be washed into the hydraulic system and cause blockage. At the same time, the existing pipe joint group usually adopts a supporting device to fix the pipe joint after the pipeline connection is completed, but the supporting device is often directly connected to the pipe joint during the installation process, which can easily cause damage to the pipe joint during the fixing process and cause economic losses. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a pipe joint group which can prevent the sealant from falling off and is convenient for installation and fixing in view of the current status of the prior art.

[0006] (II) Technical solution

[0007] The utility model is implemented through the following technical scheme: the utility model proposes a pipe joint assembly, including a pipe joint, wherein fixing plates are arranged around the pipe joint, a nail entry groove is penetrated on the fixing plate, a model plate is welded on one side of the pipe joint, connecting threads are symmetrically arranged at both ends of the pipe joint, connecting ports are penetrated in the connecting threads at both ends of the pipe joint, a hose 1 is installed in the connecting port on one side of the pipe joint, a connecting nut is sleeved on the outside of the hose 1, a fixing ring is welded to the end of the connecting nut away from the pipe joint, an expansion ring is installed at one end of the fixing ring, a filling port is arranged on one side of the expansion ring, and a hose 2 is installed in the connecting port at one end of the pipe joint away from the hose 1.

[0008] Furthermore, a fixing groove is passed through the top of the connecting nut, and a fixing block is arranged in the fixing groove.

[0009] By adopting the above technical solution, the fixing block can pass through the fixing groove to press and fix the first rubber hose and the second rubber hose.

[0010] Furthermore, the fixing block is plugged into the fixing groove, and the fixing block is adapted to the fixing groove.

[0011] By adopting the above technical solution, the fixing block and the fixing groove are firmly connected to prevent loosening and deviation during use.

[0012] Furthermore, a pipe inlet is provided through the fixing ring, and the diameters of the first rubber hose and the second rubber hose are smaller than the aperture of the pipe inlet.

[0013] By adopting the above technical solution, the first hose and the second hose can enter the fixing ring through the pipe inlet, which is convenient for subsequent use.

[0014] Furthermore, the fixing plate is welded to the pipe joint, and the number of the fixing plates is not less than four.

[0015] By adopting the above technical solution, the fixing plate and the pipe joint are firmly connected, and the pipe joint is installed on the supporting device by using the fixing plate.

[0016] Furthermore, the connecting nut is adapted to the connecting thread, and the diameters of the first hose and the second hose are smaller than the hole diameter of the connecting nut.

[0017] By adopting the above technical solution, the connecting nut can be firmly fixed to the connecting thread, and the first rubber hose and the second rubber hose can pass through the connecting nut and enter the pipe inlet.

[0018] Furthermore, the expansion ring is made of vulcanized rubber.

[0019] By adopting the above technical solution, the expansion ring has good expansion strength, thereby increasing the service life of the device.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] 1. To solve the problem that although the existing pipe joint assembly can connect the pipe through the thread and the nut, and fill the ferrule with sealant to increase the sealing performance after the connection, the sealant will fall off with the increase of the use time, causing the fallen sealant to be washed into the hydraulic system and cause blockage, the utility model provides a fixed ring and an expansion ring. After the fixed ring fixes the hose, the sealant is injected into the expansion ring to make the expansion ring expand and wrap the hose, which not only increases the sealing performance of the device, but also prevents the sealant from falling off and entering the hydraulic system to block the hydraulic system;

[0023] 2. In order to solve the problem that the existing pipe joint group usually uses a supporting device to fix the pipe joint after the pipe connection is completed, but the supporting device is often directly connected to the pipe joint during the installation process, which may easily lead to damage to the pipe joint during the fixing process and cause economic losses, the utility model provides a fixing plate and a nail entry groove. After the pipe connection is completed, the nail is passed through the nail entry groove at a suitable installation position to connect the fixing plate and the supporting device, thereby preventing damage to the pipe joint body during the installation process.
