[0003] After retrieval, in the application with the patent application number 202322216587.7, a flexible connection structure between a precast concrete inspection well and a pipe is disclosed, which includes a precast concrete inspection well, a precast concrete short pipe, and an inspection well sealing rubber ring. The precast concrete inspection well includes a precast concrete inspection well main body, and a circular reserved hole is opened inside the precast concrete inspection well main body. The precast concrete short pipe is installed inside the circular reserved hole through the inspection well sealing rubber ring. Inner surface ridges are provided around the inner surface of the inspection well sealing rubber ring, and outer surface ridges are provided on the outer surface of the inspection well sealing rubber ring. An outer flange is fixedly connected to one side of the inner surface ridges and the outer surface ridges. In the present utility model, during the installation process, the connection work between the precast concrete short pipe and the precast concrete inspection well can be made easier by cooperating with a press-fitting device. At the same time, through the deformation amount of the sealing rubber ring and the inclined surface at the end of the precast concrete short pipe, the sealing performance of the precast concrete short pipe can be ensured;

[0004] The above application document realizes the sleeving between two groups of prefabricated pipes through a sealing rubber ring with a corresponding shape. However, first, it is sleeved inside, and second, due to the flexible connection, when it is impacted by the inner fluid, it is extremely easy to cause the falling off of its clamping part, and thus the stability of a single clamping is difficult to guarantee.

[0005] Therefore, we propose a flexible connection structure for prefabricated pipes. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a flexible connection structure for prefabricated pipes, which solves the problem of poor stability of the existing single clamping.

An inner concave sleeve adapted to the specifications and shape of the inner convex block is provided inside the flexible connection rubber ring, and an outer clamping part adapted to the shape of the outer groove is fixedly installed on the inner wall of the outer ring of the flexible connection rubber ring.

[0011] Preferably, the outer groove is an annular groove in the shape of an oblique triangle, and the edge of the oblique groove of the outer groove is in the same direction as the fluid direction inside the prefabricated pipe;

[0012] Among them, the setting of the shape and direction of the outer groove can ensure the clamping effect between it and the outer clamping part. At the same time, it can increase the clamping force between them when being impacted by the water flow, further ensuring the clamping effect and avoiding the situation of falling off due to force.

[0013] Preferably, the outer groove is composed of a receiving part and a sleeved part. The sleeved part is an annular round clamp, and the bottom edge of the inner groove of the inner concave sleeve is adapted to the shape and specifications of the annular round clamp;

[0014] Among them, the setting of the annular round clamp of the outer groove can increase the contact area between it and the inner concave sleeve, thereby increasing the clamping effect.

[0015] Preferably, the receiving part is an oblique annular clamp. A clamping point part protruding outward is provided on the outer wall of the receiving part, and a clamping point groove adapted to the shape and specifications of the clamping point part is provided on the inner wall of the groove of the inner concave sleeve;

[0016] Among them, the setting of the clamping point part of the receiving part and the clamping point groove in the inner concave sleeve can increase the contact area and mutual acting force during clamping, further ensuring the clamping effect.

[0017] Preferably, inner concave sleeves and outer clamping parts are provided on both the left and right sides of the flexible connection rubber ring. The flexible connection rubber ring is clamped at the end heads of two groups of prefabricated pipes. The edge directions of the two groups of inner concave sleeves are different from the fluid flow direction, and the bottom edge directions of the two groups of outer clamping parts are the same as the fluid flow direction.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-4 , the embodiments of the present utility model provide a technical solution: a flexible connection structure for a prefabricated pipeline, including a prefabricated pipeline 1 and a flexible connection rubber ring 2 sleeved at the end of the prefabricated pipeline 1; the prefabricated pipeline 1 includes a straight pipe part 11, a conduit part 12 and a clamping part 13; three groups of inner convex blocks 131 distributed at intervals are fixedly installed on the inner side wall of the clamping part 13, and three groups of outer grooves 132 arranged at intervals are formed on the outer wall of the clamping part 13; the flexible connection rubber ring 2 is an obliquely Y-shaped rubber sleeve, an inner concave sleeve 21 adapted to the specification and shape of the inner convex block 131 is arranged on the inner side of the flexible connection rubber ring 2, and an outer clamping part 22 adapted to the shape of the outer groove 132 is fixedly installed on the inner wall of the outer ring of the flexible connection rubber ring 2;

[0027] Among them, for the flexible connection structure of the prefabricated pipeline, through the setting of the shape of the flexible connection rubber ring 2, it can be clamped between the ends of two groups of prefabricated pipelines 1, and the inner concave sleeve 21 and the outer clamping part 22 in the flexible connection rubber ring 2 are clamped on the inner and outer sides of the clamping part 13, so that the force direction is different from the clamping direction. When the flexible connection rubber ring 2 is impacted by water flow, the clamping firmness between them is continuously increased, and at the same time, the clamping operation is simple, solving the problem of poor stability of the existing single clamping.

[0028] Embodiment 2:

[0029] The outer groove 132 is an inclined triangular annular groove, and the inclined edge of the outer groove 132 is in the same direction as the fluid direction inside the prefabricated pipe 1. Among them, the shape and direction of the outer groove 132 are set to ensure the clamping effect between it and the outer clamping part 22. At the same time, it can increase the clamping force between them when being impacted by the water flow, further ensuring the clamping effect and avoiding the situation of falling off due to force.

[0030] The outer groove 132 is composed of a receiving part and a sleeving part. The sleeving part is an annular round card, and the bottom edge of the inner groove of the inner concave sleeve 21 is adapted to the shape and specification of the annular round card. Among them, the setting of the annular round card of the outer groove 132 can increase the contact area between it and the inner concave sleeve 21, thereby increasing the clamping effect.

[0031] The receiving part is an inclined annular card. There are outwardly protruding clamping points on the outer wall of the receiving part, and there are clamping point grooves on the inner wall of the groove of the inner concave sleeve 21 that are adapted to the shape and specification of the clamping points. Among them, the setting of the clamping points of the receiving part and the clamping point grooves in the inner concave sleeve 21 can increase the contact area and the mutual acting force during clamping, further ensuring the clamping effect.

[0032] Inner concave sleeves 21 and outer clamping parts 22 are provided on both the left and right sides of the flexible connection rubber ring 2. The flexible connection rubber ring 2 is clamped at the end heads of two groups of prefabricated pipes 1. The edge directions of the two groups of inner concave sleeves 21 are different from the fluid flow direction, and the bottom edge directions of the two groups of outer clamping parts 22 are the same as the fluid flow direction.

[0033] The working principle and usage process of the present utility model: When the device needs to work, the inner concave sleeve 21 inside the flexible connection rubber ring 2 is deformed and clamped outside the inner convex block 131 inside the clamping part 13. At the same time, the outer clamping part 22 is clamped in the outer groove 132 outside the clamping part 13 from the outside. The clamping effect is ensured both inside and outside. At the same time, when the fluid flows inside and impacts the flexible connection rubber ring 2, the shape and direction settings of the outer groove 132 and the outer clamping part 22, and the inner convex block 131 and the inner concave sleeve 21 can increase the mutual acting force of the clamping between them and ensure the sleeving effect.
