[0002] The structure of a bellows is as follows: the crests and troughs of the bellows surround the radial direction of the bellows, while the crests and troughs are arranged in a sequential and alternating manner along the axial direction of the bellows. Due to this structure, the bellows has great strength in the radial direction and can withstand very large pressures, but the axial force capacity of the bellows is not high and it cannot withstand large axial pressures.

[0003] In the existing technology, because the walls of the corrugated pipes are thin and the axial strength is poor, the joint of the two corrugated pipes is easily deformed and damaged when subjected to external impact after they are connected and installed. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that, due to the thin wall and poor axial strength of the corrugated pipe, the joint of the two corrugated pipes is easily deformed and damaged when subjected to external impact after being connected and installed. Therefore, this invention proposes a corrugated pipe structure to improve the axial strength of the corrugated pipe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bellows structure for improving the axial strength of a bellows, comprising: a bellows body, wherein a plurality of reinforcing rings are fixedly connected at equal intervals on the outer surface of the bellows body, a flange is provided on the front end face of the bellows body, the flange is connected to the bellows body, an installation component is provided on the front end face of the flange, and a support component is provided on the inner surface of the bellows body; the support component includes a second outer ring block, a first fixed ring block, and a second fixed ring block, wherein a plurality of inner support rods are fixedly connected at equal intervals between the first fixed ring block and the second fixed ring block, a plurality of first outer support rods are fixedly connected at equal intervals between the second outer ring block and the first fixed ring block, a plurality of second outer support rods are fixedly connected at equal intervals on the front end face of the second fixed ring block, and a third fixed ring block is fixedly connected between the end faces of the plurality of second outer support rods.

[0008] Preferably, a plurality of second reinforcing blocks are fixedly connected at equal intervals to the front end face of the first fixing ring block, and the outer surfaces of the plurality of second reinforcing blocks are fixedly connected to the inner surface of the corrugated pipe body.

[0009] Preferably, a plurality of third reinforcing blocks are fixedly connected at equal intervals to the rear end face of the second fixing ring block, and the outer surfaces of the plurality of third reinforcing blocks are fixedly connected to the inner surface of the corrugated pipe body.

[0010] Preferably, a mounting ring block is fixedly connected to the rear end face of the second outer ring block near the inner edge, and the outer surface of the mounting ring block is provided with external threads.

[0011] Preferably, the mounting assembly includes a first outer ring block, which is disposed on the front end face of the flange. The inner surface of the first outer ring block is provided with a mating groove, and the inner surface of the mating groove is provided with an internal thread.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, during use, by setting a first fixed ring block and a second fixed ring block inside the corrugated pipe body respectively, its radial strength is increased. The first fixed ring block and the second fixed ring block are connected by multiple inner support rods, and their outer sides are respectively connected to the second outer ring block and the first outer ring block by multiple first outer support rods and second outer support rods. This greatly increases the axial strength of the corrugated pipe when it is subjected to external impact, making it less prone to deformation and damage.

In this utility model, during use, multiple first reinforcing blocks are fixedly connected at equal intervals between the second outer ring block and the outer surface of the corrugated pipe body, thereby increasing the connection effect between the second outer ring block and the corrugated pipe body. By fixing multiple second and third reinforcing blocks to the opposite surfaces of the first and second fixed ring blocks respectively, the connection effect between the first and second fixed ring blocks and the corrugated pipe body is increased, making it less prone to falling off and deformation, thus improving its practicality.

A plurality of second outer support rods 509 are fixedly connected at equal intervals to the front end face of the second fixed ring block 511. A third fixed ring block 510 is fixedly connected between the end faces of the plurality of second outer support rods 509. The front end face of the second outer ring block 501 is fixedly connected to the rear end face of the corrugated pipe body 1. The outer surfaces of the first fixing ring block 505 and the second fixing ring block 511 are fixedly connected to the inner surface of the bellows body 1.

The outer surface of the mounting ring block 502 has an external thread 503. The mounting assembly 4 includes a first outer ring block 401, which is disposed on the front end face of the flange 3. The inner surface of the first outer ring block 401 has a mating groove 402, and the inner surface of the mating groove 402 has an internal thread 403. 03. The internal thread 403 and the external thread 503 are matched. The rear end face of the first outer ring block 401 is fixedly connected with multiple threaded rods 404 at equal intervals. The outer surfaces of the multiple threaded rods 404 are threadedly rotatably connected with nuts 405. The outer surface of the third fixing ring block 510 is in contact with the inner surface of the bellows body 1. The front end face of the third fixing ring block 510 is in contact with the rear end face of the first outer ring block 401. The front end face of the flange 3 is provided with multiple mounting holes 6 at equal intervals. The mounting holes 6 and the threaded rods 404 are matched.

[0027] The overall effect of Embodiment 1 is as follows: To improve the axial strength of the bellows, multiple reinforcing rings 2 are equidistantly arranged on the outer surface of the bellows body 1 to increase its radial strength. A flange 3 is provided at the front end of the bellows body 1, with multiple mounting holes 6 equidistantly opened on its surface. A threaded rod 404 fixedly connected to the surface of the first outer ring block 401 passes through the flange 3. After multiple nuts 405 are threaded onto the surfaces of the multiple threaded rods 404, the first outer ring block 401 is fixedly connected to the front end of the bellows body 1 for installation. A mating groove 402 is provided on its inner surface, and an internal thread 403 is provided on the inner surface of the mating groove 402 for installation. A second outer ring block 501 is fixedly connected to the rear end of the bellows body 1, increasing the contact surface for bellows mating. An mounting ring block 502 is fixedly connected to the inner side of its rear end face, and an external thread 503 is provided on the outer surface of the mounting ring block 502 for mating with the internal thread 403 of another bellows. 03. The bellows body 1 is installed by threaded connection. The inner surface of the bellows body 1 is fixedly connected with a first fixing ring block 505 and a second fixing ring block 511. Multiple inner support rods 507 are fixedly connected between the two at equal intervals.

The front end face of the second fixing ring block 511 is in contact with the rear end face of the first outer ring block 401. When the bellows is subjected to axial impact, the axial strength of the bellows body 1 is increased by the combined action of multiple inner support rods 507, first outer support rods 508 and second outer support rods 509, making it less prone to deformation and damage. This solves the problem in the background technology that the bellows wall is thin and the axial strength is poor. After the two bellows are installed together, the joint of the bellows is prone to deformation and damage when subjected to external impact.

[0028] Example 2: As Figures 1-5 As shown, a plurality of first reinforcing blocks 504 are fixedly connected at equal intervals on the front end face of the second outer ring block 501, and the outer surfaces of the plurality of first reinforcing blocks 504 are fixedly connected to the outer surface of the corrugated pipe body 1. A plurality of second reinforcing blocks 506 are fixedly connected at equal intervals on the front end face of the first fixing ring block 505, and the outer surfaces of the plurality of second reinforcing blocks 506 are fixedly connected to the inner surface of the corrugated pipe body 1.

[0029] The overall effect of Embodiment 2 is that, during use, by equidistantly fixing multiple first reinforcing blocks 504 between the second outer ring block 501 and the outer surface of the corrugated pipe body 1, the connection effect between the second outer ring block 501 and the corrugated pipe body 1 is increased. By fixing multiple second reinforcing blocks 506 and third reinforcing blocks 512 on the opposite surfaces of the first fixed ring block 505 and the second fixed ring block 511, the connection effect between the first fixed ring block 505 and the second fixed ring block 511 and the corrugated pipe body 1 is increased, making it less prone to falling off and deformation, and thus highly practical.

[0030] Working principle: To improve the axial strength of the bellows, multiple reinforcing rings 2 are equidistantly arranged on the outer surface of the bellows body 1 to increase the radial strength of the bellows. A flange 3 is provided at the front end of the bellows body 1, and multiple mounting holes 6 are equidistantly opened on its surface. The threaded rods 404 fixedly connected to the surface of the first outer ring block 401 pass through the flange 3. After multiple nuts 405 are threadedly connected to the surfaces of the multiple threaded rods 404, the first outer ring block 401 is fixedly connected to the front end of the bellows body 1 for installation. A mating groove 4 is opened on its inner surface. 02, and the inner surface of the mating groove 402 is provided with an internal thread 403 for installation. By fixing the second outer ring block 501 to the rear end of the bellows body 1, the contact surface for bellows mating is increased. The inner side of its rear end face is fixedly connected with an installation ring block 502, and the outer surface of the installation ring block 502 is provided with an external thread 503 for threaded connection with the internal thread 403 of another bellows for mating installation. The inner surface of the bellows body 1 is fixedly connected with a first fixing ring block 505 and a second fixing ring block 511, which are fixedly connected at equal intervals. There are multiple inner support rods 507. The rear end face of the first fixing ring block 505 is fixedly connected to the second outer ring block 501 by multiple first outer support rods 508. The front end face of the second fixing ring block 511 is fixedly connected to the third fixing ring block 510 by multiple second outer support rods 509, and the front end face of the second fixing ring block 511 is in contact with the rear end face of the first outer ring block 401. When the bellows is subjected to axial impact, the combined action of the multiple inner support rods 507, the first outer support rods 508, and the second outer support rods 509 increases the axial force of the bellows body 1. To enhance strength and prevent deformation and damage, multiple first reinforcing blocks 504 are fixedly connected at equal intervals between the second outer ring block 501 and the outer surface of the bellows body 1, thereby increasing the connection between the second outer ring block 501 and the bellows body 1. Multiple second reinforcing blocks 506 and third reinforcing blocks 512 are fixedly connected to the opposite surfaces of the first fixed ring block 505 and the second fixed ring block 511, respectively, thereby increasing the connection between the first fixed ring block 505 and the second fixed ring block 511 and the bellows body 1, making it less prone to detachment and deformation, and thus highly practical.
