[0024] Reference to "an embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily all referring to a common set of embodiments, although they can be.

[0025] Embodiments of the application will be described in detail below with reference to the attached drawings, which show examples of the embodiments, and in which: Figures 1-2 The technical solutions in the embodiments of the application are clearly and completely described.

[0026] The main purpose of the present application is to provide a novel pipeline connection structure, comprising a pipe 1 and a pipe 2, both of which are connected by insertion, and the pipe 1 is provided with a limiting area 11 at the end, the limiting area 11 comprises a limiting ring 111 and an abutting portion 112 arranged along the circumference of the pipe at a distance from the limiting ring, the limiting ring 111 and the abutting portion 112 and the area between them form the limiting area 11; the pipe 2 is provided with a clamping block 21 at the end, the clamping block is matched with the limiting area; when the pipe is inserted into the pipe for connection, the clamping block 21 enters the limiting area 11, and the pipe connection structure is connected; the outer wall of the clamping block 21 is in close contact with the outer wall of the limiting area 11, the clamping block 21 is limited by the abutting portion 112, the outer wall of the pipe 1 and the limiting ring 111 respectively, and cannot move along the direction of the pipe, but the pipe 1 and the pipe 2 can rotate relative to each other, and in the embodiment, the pipe 2 is provided as a bent pipe, and the rotation of the pipe can realize the adjustment of the connection direction of the pipeline.

[0027] The vertical section 1 of the clamping block 21 passing through the center of the pipe is a trapezoidal shape, when the pipe is inserted, it travels along the slope direction of the inclined edge of the trapezoidal section, the slope is arranged to facilitate the sliding of the pipe, when the pipe passes through the clamping block, the travel space becomes smaller along the slope of the inclined edge, the extrusion force becomes larger and larger, the clamping block deforms instantaneously under the pressure, and when the clamping block enters the limiting area 11 completely, the extrusion force on the clamping block disappears, and the deformation of the clamping block completely recovers.

[0028] The vertical section 2 of the abutting portion 112 passing through the center of the pipe is a trapezoidal shape, and after the pipe is connected, the inclined edge of the section 2 is in close contact with the inclined edge of the section 1, the inclined edge of the abutting portion 112 and the inclined edge of the clamping block have the same inclination angle, and the abutting portion 112 is in close contact with the clamping block.

[0029] In the embodiment, the abutting portion 112 is discontinuously arranged on the circumference of the pipe, and when the pipe rotates, the clamping block can always have an abutting portion with the clamping block.

[0030] In another embodiment, the abutting portion is continuously arranged on the circumference of the pipe.

[0031] An opening 22 is provided in the pipe wall below the locking block 21. The opening 22 is used to accommodate the instantaneous deformation of the locking block 21 during insertion. After the locking block 21 reaches the limiting area 11, it recovers its deformation. In this embodiment, the opening 22 and the locking block 21 are of the same width and are arranged vertically adjacent to each other. The equal width of the opening 22 facilitates the instantaneous deformation and recovery of the locking block when it is squeezed, thereby reducing the difficulty of insertion due to the deformation of the locking block. It can also avoid irreversible deformation caused by the difficulty of deformation of the locking block during insertion, which would affect the use of the locking block.

[0032] An outer edge 12 is provided at the end of the insertion tube 1. When the insertion tube 1 is inserted and the insertion is completed, the end of the support tube 2 is attached to the outer edge 12 of the insertion tube. The outer edge 12 further limits the insertion depth, so that the support tube 2 and the outer surface of the insertion tube 1 are integrated.

[0033] To enhance the sealing performance of this novel pipe connection structure, an elastic sealing ring 113 is provided on one side of the non-limiting area of ​​the limiting ring 111. During insertion, the sealing ring 113 is elastically fixed to the outer wall of the insertion tube 1, and the non-limiting area of ​​the limiting ring 111 restricts its displacement along the insertion direction. The sealing ring 113 can improve the sealing performance between the socket and the insertion tube. In this embodiment, discontinuous holes 114 are provided on the insertion tube 1 at the location where the elastic sealing ring is provided on the limiting ring 111, which is used to release excess deformation during the operation of the elastic sealing ring. The elastic sealing ring 113 deforms and blocks the gap between the socket 2 and the insertion tube 1 during mutual compression.
