In this embodiment, referring to fig. 1, when the joint assembly is connected to the first pipe, the end of the first pipe is first contacted with the inner side surface of the sealing block 201, and the sealing block 201 is elastically deformed along with the axial movement of the first pipe, so that the first pipe can reach the installation position of the joint assembly. The first sealing element 200 has elasticity, and when the first pipeline presses the sealing block 201, the first sealing element 200 has a tendency of recovering deformation, so that the plurality of sealing blocks 201 are in contact with the outer side wall of the first pipeline, and the tightness between the joint assembly and the first pipeline is good. The deformation groove 202 can enable the deformation amount of the sealing block 201 to be larger, and the phenomenon that the deformation amount of the sealing block 201 is smaller to prevent the first pipeline from moving is avoided. The first pipe refers to a pipe connected to the pipe joint and capable of contacting the first seal member 200, and the size and material of the first pipe are not limited.
Referring to fig. 2, the cross section of the sealing block 201 may be wedge-shaped, i.e., the inner side surface of the sealing block 201 is inclined toward the insertion direction of the first pipe; at this time, the opening direction of the deformation groove 202 may be the same as the insertion direction of the first pipe, and may also be directed toward the outer sidewall of the first seal 200. Referring to fig. 3, the cross section of the sealing block 201 may also be arc-shaped, in which case the opening direction of the deformation groove 202 may be toward the outer sidewall of the first seal member 200. Referring to fig. 4, the cross section of the sealing block 201 may also be spherical, in which case the opening of the deformation groove 202 may be directed toward the central axis of the first seal member 200.
In this embodiment, referring to fig. 1 and 2, the cross section of either sealing block 201 may be wedge-shaped, and the inner diameter of the sealing block 201 gradually decreases from one end near the first pipe toward one end near the second pipe. The wedge-shaped sealing block 201 is convenient to process, the sealing block 201 can be formed by cutting by a turning tool, and the sealing block 201 can be formed by injection molding with the first sealing piece 200.

In detail, the number of the sealing rings 203 may be 2, the cross section of the sealing block 201 may be wedge-shaped, and the opening direction of the deformation groove 202 may be the same as the insertion direction of the first pipe.
In this embodiment, referring to fig. 2, the outer sidewall of the first seal member 200 is provided with an arcuate projection 204. In detail, the main function of the arc-shaped protrusion 204 is to increase the outer diameter of the first seal member 200, so that the first seal member 200 is firmly mounted with the joint assembly; a certain gap is formed between the joint component and the part of the first sealing element 200 except the arc-shaped protruding blocks 204, and when the first sealing element 200 is pressed and deformed, part of the side wall is contacted with the joint component, so that the deformation of the first sealing element 200 is prevented from being small and the movement of the first pipeline is prevented.

The clip spring 111 may be made of SUS304 stainless steel, and the clip spring 111 has a certain elastic deformation capability. The inner diameter of the clamp spring 111 is smaller than the outer diameter of the first pipeline, so that the first pipeline can squeeze the clamp spring 111 to deform.
