[0021] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] See also Figure 1-4 As shown, an embodiment of the present application discloses a pipe connection joint with high connection strength, including a joint body 1, and the inner side of each connection end of the joint body 1 is sequentially provided with a first annular groove 11 and a second annular groove 12 from the outside to the inside, and each first annular groove 11 and the second annular groove 12 are respectively clamped with a toothed ring 2 and a sealing ring 3; when the end of the pipe is inserted into the connection end of the joint body 1, and the connection end of the joint body 1 is clamped by a clamping device, the toothed ring 2 is used to clamp with the end of the pipe to lock the pipe and the joint body 1; a plurality of annular convex teeth 21 are arranged on the inner circumferential wall of each toothed ring 2, which are spaced apart along the axial direction of the corresponding toothed ring 2; when the connection end of the joint body 1 is clamped by the clamping device, the connection end of the joint body 1 is used to squeeze the toothed ring 2 so that the annular convex teeth 21 are clamped with the outer wall of the pipe.
