[0012] Figure 1 This is a schematic diagram of a corrugated pipe repair device provided by this utility model;

[0013] Figure 2 This is an exploded view of a corrugated pipe repair device provided by this utility model; Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] Reference Figure 1 , Figure 2 This utility model provides a corrugated pipe repair device, which mainly includes a support ring 1, a drive disc 2, several support rods 5, a handle 3, a tightening handle 4, and a shaping tile 6, etc.

[0016] The support ring 1 consists of two fixedly connected plate rings 101. On the adjacent side of each of the two plate rings 101, there is a receiving groove 102, a telescopic groove 103, and a driving groove 104. When the two plate rings 101 are fixedly connected, the two receiving grooves 102 are combined to form an annular groove on the inner surface of the support ring 1. A handle 3 is fixedly installed on the outer side of the support ring 1. The handle 3 is designed to facilitate operation by holding the repair device.

[0017] The drive disk 2 is disposed within the support ring 1 and is able to rotate freely within the support ring 1. The drive disk 2 consists of two base disks 202 fixedly connected by support columns 203. Each base disk 202 has several arc-shaped guide grooves 201 arranged circumferentially, and the arc-shaped guide grooves 201 penetrate the base disk 202. The arc-shaped guide grooves 201 on the two base disks 202 correspond to each other, providing a sliding track for the guide column 501 on the support rod 5. The outer edge of the base disk 202 is provided with limiting ears 204. The two limiting ears 204 are kept within the annular groove on the inner surface of the support ring 1 and slide freely. Through the cooperation of the limiting ears 204 and the annular groove, the drive disk 2 can be stably rotated within the support ring 1, while restricting the axial movement of the drive disk 2. The drive disk 2 is also provided with a tightening handle 4, which passes through the drive groove 104 on the support ring 1 and is fixedly connected to the drive disk 2. The operator can drive the drive disk 2 to rotate by operating the tightening handle 4.

[0018] A spring 301 is provided on the side of the grip 3 adjacent to the tightening handle 4. The spring 301 is folded from the grip 3 toward the tightening handle 4. During operation, the spring 301 can play a certain role in buffering and resetting.

[0019] The support rod 5 is arranged radially along the support ring 1. One end of the support rod 5 passes through the telescopic groove 103 on the support ring 1, and the other end is provided with a shaping tile 6. The end of the support rod 5 that passes through the support ring 1 is located between two base plates 202 and has a guide post 501. The two ends of the guide post 501 are respectively located in the arc-shaped guide grooves 201 on the two base plates 202 and can slide freely within the arc-shaped guide grooves 201. When the drive disc 2 rotates, the shape and position of the arc-shaped guide grooves 201 change, thereby driving the guide post 501 to slide within the arc-shaped guide grooves 201, and thus causing the support rod 5 to move radially along the support ring 1, realizing the telescopic function of the support rod 5. At the same time, the shaping tile 6 is detachably set on the support rod 5. This detachable design makes it easy to replace the appropriate shaping tile 6 according to different specifications of corrugated pipes, improving the versatility of the repair device.

[0020] The working principle of this solution is as follows:

[0021] When the bellows needs repair, the operator holds the handle 3 on the support ring 1 and places the repair device into the bellows to be repaired. At this time, the handle 3 and the tightening handle 4 are on the radial surface of the bellows, making it easy for the operator to apply force. Then, the operator operates the tightening handle 4, which drives the drive disc 2 to rotate, causing the guide column 501 to slide within the arc-shaped guide groove 201, thereby pushing the support rod 5 to move outward along the radial direction of the support ring 1. The shaping tile 6 at the other end of the support rod 5 expands outward, applying pressure to the inner wall of the bellows. Rotating the repair device causes the shaping tile 6 to slide along the inner wall of the bellows, gradually restoring the deformed inner wall of the bellows to its original shape, thus achieving the purpose of repairing the bellows. After the repair is completed, the operator releases the tightening handle 4. Under the restoring force of the spring 301, the support rod 5 retracts inward under the action of the arc-shaped guide groove 201, and the shaping tile 6 detaches from the inner wall of the bellows, allowing the repair device to be removed from the bellows.

[0022] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
