[0021] In order to make the above objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0022] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

In addition, the three-dimensional spatial dimensions of length, width and depth should be included in actual production.

[0024] Thirdly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments.

[0025] Embodiment 1

[0026] Reference Figures 1 to 5 The present embodiment provides a clamping type pipe flat sealing structure, which comprises a sleeve 100 and a pipe 200, the sleeve 100 and the pipe 200 are both tubular, the sleeve 100 is sleeved on the outer wall of the pipe 200; a clamping mechanism, the clamping mechanism comprises a joint 201 and a guide block 101, the joint 201 is arranged at the end of the pipe 200, the guide block 101 is arranged at the inner wall of the sleeve 100, and the guide block 101 and the joint 201 cooperate with each other.

[0027] The joint 201 and the joint 201 are integrally formed, the cross section of the joint 201 is a non-circular symmetric figure, a plurality of groups of guide blocks 101 are fixedly connected with the inner wall of the sleeve 100, and the cross section shape of the plurality of groups of guide blocks 101 and the joint 201 is circular when combined; when the sleeve 100 and the pipe 200 are sleeved, the sleeve 100 and the pipe 200 are guided due to the shape cooperation of the joint 201 and the guide block 101, so as to avoid the sealing problem of the sleeve 100 and the pipe 200 when the sleeve 100 and the pipe 200 are sleeved because the sleeve 100 and the pipe 200 are not coaxial.

[0028] The outer wall of the guide block 101 is provided with a plurality of insertion grooves 101a, and each group of guide blocks 101 is internally provided with a ring groove 101b. The ring groove 101b is internally and slidably provided with a clamping ring 102. The ring groove 101b and the clamping ring 102 are annular. One side of the outer wall of the connector 201 is provided with a protrusion 201a. The protrusion 201a is slidably connected in the insertion groove 101a. When the sleeve 100 is sleeved with the insertion tube 200, the protrusion 201a slides in the insertion groove 101a. When the protrusion 201a contacts the clamping ring 102, the clamping ring 102 is pushed to slide in the ring groove 101b. With the sliding of the clamping ring 102, the other end of the clamping ring 102 contacts and abuts against the protrusion 201a, so that the protrusion 201a cannot continue to slide, thereby determining the feeding depth of the insertion tube 200 in the sleeve 100.

[0029] The distance between the ring groove 101b and the clamping ring 102 in each group of insertion grooves 101a is different. Before sleeving, the insertion tube 200 is rotated to slide in different insertion grooves 101a, thereby adjusting the limit feeding depth of the insertion tube 200, so that a single pipe has a wider application scenario. It should be noted that when the outer wall of the connector 201 is only provided with a single protrusion 201a, the distance between the ring groove 101b and the clamping ring 102 in each group of insertion grooves 101a is different. When the connector 201 is provided with two groups of protrusions 201a, the distance between the ring groove 101b and the clamping ring 102 in each group of insertion grooves 101a is the same, and the distance between the ring groove 101b and the clamping ring 102 in the adjacent guide block 101 is different. For details, please refer to Figures 2 to 3 .

[0030] The inner wall of the sleeve 100 is provided with a pressing groove 103, and the pressing groove 103 is internally embedded with a sealing ring 103a. The structure is a normal clamping and pressing type sealing structure, which will not be described in detail here.
