Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe fittings technology, and in particular to a spherical sleeve for corrugated pipes. Background Technology

[0002] Corrugated tubes are flexible pipes with a corrugated structure, widely used in various fields such as industry, construction, automotive, and medical. Their unique corrugated design gives them excellent flexibility, extensibility, and pressure resistance. The structure typically consists of alternating crests and troughs, similar to the pleats of an accordion. This structure allows them to bend and stretch without easily breaking. Different materials are used in modern industrial production, making corrugated tubes an important component of modern industry.

[0003] Corrugated pipe fittings are various components used to connect, secure, redirect, or seal corrugated pipes, ensuring the integrity, flexibility, and functionality of piping systems. Depending on the material of the corrugated pipe (e.g., metal, plastic) and the application (e.g., drainage, cable protection, industrial piping), the types and functions of fittings vary, including corrugated pipe anti-collision balls, sleeves, and bracing. Among these, sleeves are commonly used in corrugated pipe systems, primarily for connecting, protecting, or extending corrugated pipes.

[0004] Existing corrugated pipes are usually used to wrap cables, so different cables require different diameter corrugated pipes. When installing the corrugated pipe sleeve, the different diameters of the corrugated pipes can lead to mismatches in the sleeve size, resulting in a limited range of applications. Therefore, in order to solve the above technical problems, this utility model proposes a spherical sleeve for corrugated pipes.

[0005] content

[0006] The purpose of this utility model is achieved through the following method: a spherical sleeve for a corrugated pipe, comprising a first hemispherical cylinder, a second hemispherical cylinder, and a positioning assembly. The positioning assembly includes a side limiting block, a first limiting block, and a second limiting block. An opening is provided on one side of both the first and second hemispherical cylinders. A mounting platform is provided on the outer surface of both the first and second hemispherical cylinders near the opening. The side limiting block, the first limiting block, and the second limiting block are all disposed opposite each other on the mounting platform. The first limiting block is disposed opposite each other in the middle of one side of the mounting platform, and the second limiting block is disposed opposite each other between the first limiting block and the side limiting block. A locking block is provided on the mounting platform near the first and second limiting blocks. An adjustment groove matching the locking block is provided on the first and second limiting blocks near the locking block. A threaded hole is provided on the side of the locking block away from the mounting platform. A connecting bolt is provided on the first and second limiting blocks near the threaded hole. The screw of the connecting bolt passes through the adjustment groove and is detachably connected to the threaded hole.

[0007] In a further embodiment of the above description, the first hemispherical cylinder is positioned above the second hemispherical cylinder, with the bottom surface of the first hemispherical cylinder and the top surface of the second hemispherical cylinder in contact. Both the bottom surface of the first hemispherical cylinder and the top surface of the second hemispherical cylinder are provided with mounting grooves for installing the corrugated pipe. The mounting grooves are connected to the opening, and positioning protrusions are distributed within the mounting grooves. The positioning protrusions are used to provide a positioning and fixing effect with the corrugations on the corrugated pipe.

[0008] In a further embodiment of the above description, mounting posts are provided on the bottom surface of the first hemispherical cylinder and the top surface of the second hemispherical cylinder near the positioning protrusion, and a positioning groove matching the mounting post is provided on one side of each mounting post; the positioning groove and the mounting post are used to connect the first hemispherical cylinder and the second hemispherical cylinder.

[0009] In the above description, as a further embodiment, both the first hemispherical cylinder and the second hemispherical cylinder are provided with an inlet on the side away from the opening. The inlet communicates with the mounting groove. The first hemispherical cylinder and the second hemispherical cylinder are provided with anti-wear rings near the inlets. The anti-wear rings are connected to the inlets. The anti-wear rings can effectively reduce the wear effect of the bellows.

[0010] In a further embodiment of the above description, one end of the anti-wear ring is provided with a mounting position, and a connecting screw hole for connection is opened in the middle of the mounting position. A mounting groove is provided near the connecting screw hole in the mounting position. The end of the anti-wear ring away from the mounting position is provided with a connecting position that matches the mounting position. A positioning ring that matches the mounting groove is provided on the connecting position. A through hole is provided in the middle of the connecting position. The through hole extends through the bottom of the top of the connecting position. When the first hemispherical cylinder and the second hemispherical cylinder are installed, the bolt can be inserted into the connecting screw hole through the through hole for threaded connection.

[0011] In the above description, as a further embodiment, a first swing block and a second swing block are provided on the side of the first and second limiting blocks away from the mounting platform. The first swing block is connected to the first limiting block through a first connecting plate, and the second swing block is connected to the second limiting block through a second connecting plate. The bottom of the first limiting block, the second limiting block, the first swing block, and the second swing block are all provided with locking protrusions; the locking protrusions are used to provide the effect of connecting the corrugations on the corrugated pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up locking blocks, adjusting grooves, threaded holes and connecting bolts, when facing a bellows with a smaller diameter, the clamping force applied to the first limiting block and the second limiting block can be reduced by loosening the connecting bolts. Then, the first limiting block and the second limiting block can be adjusted to move toward the corrugations on the bellows. When they move to the corresponding positions, the connecting bolts can be tightened to re-tighten the first limiting block and the second limiting block, thereby achieving the effect of fixing the bellows and thus adapting to bellows with small diameters.

The first limiting block 4 and the second limiting block 5 are provided with an adjustment groove 9 that matches the locking block 8 near the locking block 8. A threaded hole 10 is provided on the side of the locking block 8 away from the mounting platform 7. A connecting bolt 11 is provided on the first limiting block 4 and the second limiting block 5 near the threaded hole 10. The screw of the connecting bolt 11 passes through the adjustment groove 9 and is detachably connected to the threaded hole 10.

[0027] The first hemispherical cylinder 1 is positioned above the second hemispherical cylinder 2, with the bottom surface of the first hemispherical cylinder 1 and the top surface of the second hemispherical cylinder 2 in contact. The bottom surface of the first hemispherical cylinder 1 and the top surface of the second hemispherical cylinder 2 are both provided with mounting grooves 12 for corrugated pipe installation. The mounting grooves 12 are connected to the opening 6, and positioning protrusions 14 are distributed in the mounting grooves 12.

[0028] The bottom surface of the first hemispherical cylinder 1 and the top surface of the second hemispherical cylinder 2 are provided with mounting posts 15 near the positioning protrusion 14, and one side of each mounting post 15 is provided with a positioning groove 16 that matches the mounting post 15.

[0029] Both the first hemispherical cylinder 1 and the second hemispherical cylinder 2 have an inlet 17 on the side away from the opening 6. The inlet 17 is connected to the mounting groove 12. The first hemispherical cylinder 1 and the second hemispherical cylinder 2 are provided with anti-wear rings 18 near the inlet 17. The anti-wear rings 18 are connected to the inlet 17.

[0030] One end of the anti-wear ring 18 is provided with a mounting position 19. A connecting screw hole 20 for connection is opened in the middle of the mounting position 19. A mounting slot 21 is provided near the connecting screw hole 20 in the mounting position 19.

[0032] The usage process of this utility model is as follows: After placing the corrugated pipe between the mounting groove 12 on the first hemispherical cylinder 1 and the second hemispherical cylinder 2, align the positioning protrusion 14 in the mounting groove 12 with the spacing between the corrugations on the corrugated pipe. After alignment, align the mounting post 15 on the first hemispherical cylinder 1 and the positioning groove 16 on the second hemispherical cylinder 2. Then, attach the bottom surface of the first hemispherical cylinder 1 to the top surface of the second hemispherical cylinder 2. After attachment, the connecting bolt can be passed through the through hole 24 and moved toward the connecting screw hole 20, while making a threaded connection with the connecting screw hole 20 to achieve installation and fixation.

[0033] When the diameter of the bellows is too small, the clamping force applied to the first limiting block 4 and the second limiting block 5 can be reduced by loosening the connecting bolt 11. Then, the first limiting block 4 and the second limiting block 5 can be adjusted to move towards the gap between the corrugations on the bellows. When they are moved to the corresponding positions, the connecting bolt 11 can be tightened to re-tighten the first limiting block 4 and the second limiting block 5, thereby achieving the effect of fixing the bellows.
