DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Embodiment 1

[0026] As Figures 1-3 shown, a reinforced single rubber sleeve water-blocking sleeve connection structure proposed by the present invention includes a sleeve, a rubber sleeve, and a limit buckle assembly. The rubber sleeve is arranged on the inner wall of the sleeve; the limit buckle assembly is connected to the sleeve, and there are two groups of limit buckle assemblies symmetrically arranged with respect to the rubber sleeve. The limit buckle assembly includes an inverted buckle assembly and / or a buckle plate assembly. The inverted buckle assembly includes a plurality of uniformly distributed inverted buckles 2, and the inverted buckle 2 has a guiding inclined surface that gradually inclines towards the rubber sleeve direction away from the inner wall of the sleeve. The guiding inclined surface facilitates guiding the insertion process of the corrugated pipe 100. Both groups of inverted buckle assemblies are located between the two groups of buckle plate assemblies.

[0027] The sleeve is sleeve a11, and there are two groups of opening assemblies a arranged on the sleeve a11. The opening assembly a includes a plurality of uniformly distributed openings a in a ring shape. The buckle plate assembly includes a plurality of straight plate parts 111 uniformly distributed in a ring shape. The straight plate part 111 is integrally connected at the opening a, and the straight plate part 111 gradually inclines towards the inner side of the sleeve from the end connected to the opening a to the other end. When inserting the corrugated pipe 100, the corrugated pipe 100 will push the straight plate part 111 to deform. When the corrugated pipe 100 abuts against the rubber sleeve, the straight plate part 111 will rebound and get stuck in the trough of the corrugated pipe 100.

[0028] This embodiment can effectively ensure the stability and sealing performance after connecting the corrugated pipes, and only uses one rubber sleeve for sealing, saving materials. The rubber sleeve is pre-set on the inner wall of the sleeve a11. During use, directly insert two corrugated pipes 100 from both ends of the sleeve a11 until the two corrugated pipes 100 abut. At this time, the corrugated pipe 100 contacts the rubber sleeve to achieve sealing. The inverted buckle 2 in the inverted buckle assembly will get stuck in a trough of the corrugated pipe 100, and the straight plate part 111 in the buckle plate assembly will get stuck in another trough of the corrugated pipe 100. The inverted buckle assembly and the buckle plate assembly can be individually limited by getting stuck in the trough of the corrugated pipe 100, or they can work together to limit the corrugated pipe 100 at the same time. The inverted buckle assembly and the buckle plate assembly effectively guarantee the reliability after connecting the corrugated pipe 100, thereby ensuring the sealing effect between the corrugated pipe 100 and the rubber sleeve.

[0029] Furthermore, a plurality of reinforcing ribs a are arranged on the outer peripheral surface of the sleeve along its circumferential direction; a plurality of reinforcing ribs b are uniformly arranged on the outer peripheral surface of the sleeve between two adjacent reinforcing ribs a along its circumferential direction; the width value and thickness value of the reinforcing rib a are both correspondingly greater than the width value and thickness value of the reinforcing rib b; two adjacent reinforcing ribs b and between the reinforcing rib b and the reinforcing rib a are connected by a plurality of reinforcing ribs c; a plurality of reinforcing ribs c are all connected to the outer peripheral surface of the sleeve, and each reinforcing rib c is in a strip shape or a mesh shape or a wavy line shape, etc. By setting the reinforcing rib a, the reinforcing rib b, and the reinforcing rib c, the strength of the overall connection structure can be effectively improved, and it is not easy to deform after connecting the corrugated pipe 100, the load-bearing capacity is improved, and it is not easy to deform due to soil pressure when buried underground.

[0030] Example Two

[0031] As Figure 4 shown, a reinforced single rubber sleeve water-blocking sleeve connection structure proposed by the present invention. Compared with Example One, in this embodiment, the sleeve is sleeve b12, and there are two groups of opening components b provided on the sleeve b12. The opening component b includes a plurality of openings b evenly distributed in a ring shape. The buckle plate component includes a plurality of bent plate parts 121 evenly distributed in a ring shape. The bent plate part 121 is integrally connected to the opening b, and the bent plate part 121 gradually bends towards the inner side of the sleeve along the direction from the end connected to the opening b to the other end. When inserting the corrugated pipe 100, the corrugated pipe 100 will push the bent plate part 121 to deform. When the corrugated pipe 100 abuts against the rubber sleeve, the bent plate part 121 will rebound and get stuck in the trough of the corrugated pipe 100, realizing the limit after the connection of the corrugated pipe 100 in another structural form.

[0032] Example Three

The inner folding plate part 131 is integrally connected to the end of the sleeve c13, and the inner folding plate part 131 gradually inclines towards the inner side of the sleeve c13 along the direction away from the end of the sleeve c13. A notch a is formed between adjacent two inner folding plate parts 131, and the notch a extends to the sleeve c13. The notch a can ensure the smooth deformation of the inner folding plate part 131. When inserting the corrugated pipe 100, the corrugated pipe 100 will push the inner folding plate part 131 to deform inwards. When the corrugated pipe 100 abuts against the rubber sleeve, the inner folding plate part 131 will rebound and get stuck in the trough of the corrugated pipe 100, realizing the limit after the connection of the corrugated pipe 100 in another structural form.

A notch b is formed between adjacent two outer folding plate parts 141, and the notch b extends to the sleeve d14. When connecting the corrugated pipe 100, the outer folding plate part 141 is pried open outwards through the notch b, and the corrugated pipe 100 is inserted into the sleeve. When the corrugated pipe 100 abuts against the rubber sleeve, the outer folding plate part 141 is released, and the outer folding plate part 141 will rebound and get stuck in the trough of the corrugated pipe 100, realizing the limit after the connection of the corrugated pipe 100 in another structural form.

A circular groove is provided in the middle of the outer peripheral surface of sleeve f16, and an inwardly convex ring portion 161 is formed inside the sleeve; the rubber sleeve is rubber sleeve d44, and rubber sleeve d44 is wrapped outside the inwardly convex ring portion 161. Rubber sleeve d44 can be firmly wrapped on the inwardly convex ring portion 161, and the inwardly convex ring portion 161 plays a certain supporting role for rubber sleeve d44, and can ensure effective positioning and sealing of the two bellows 100.

The positioning member a31 includes a connecting portion a and a limiting portion a. The connecting portion a is connected to the inner wall of the sleeve. The cross-section of the limiting portion a along the radial direction of the sleeve is a triangle. The bottom edge of the triangle is connected to the connecting portion a. The size of the bottom edge of the triangle is greater than the width of the connecting portion a. The vertex opposite to the bottom edge of the triangle faces the inner peripheral surface of the rubber sleeve; the rubber sleeve is rubber sleeve a41, and rubber sleeve a41 is wrapped outside the positioning member a31. The limiting portion a can effectively prevent the rubber sleeve a41 from falling off the positioning member a31, so that the rubber sleeve a41 can stably position and seal the bellows 100.

The rubber sleeve is a rubber sleeve b42, and the rubber sleeve b42 is wrapped outside the positioning member b32. Since the length of the lower base of the trapezoid is greater than the length of the upper base, after the rubber sleeve b42 is wrapped on the positioning member b32, the limiting portion b can effectively prevent the rubber sleeve b42 from falling off, so that the rubber sleeve b42 can be used to effectively position and seal the bellows 100 on both sides.
