[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0022] Appendix Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0023] See attached document Figures 1-5 The self-adhesive pavement local repair blanket includes a repair blanket body and a limiting device. The repair blanket body includes an anti-wear layer 1, a high-viscosity asphalt layer 2, a crack-resistant layer 3, and an adhesive layer 4, arranged sequentially from top to bottom. The top surface of the high-viscosity asphalt layer 2 is bonded to the bottom surface of the anti-wear layer 1, the bottom surface of the high-viscosity asphalt layer 2 is bonded to the top surface of the crack-resistant layer 3, and the bottom surface of the crack-resistant layer 3 is bonded to the top surface of the adhesive layer 4. The limiting device is disposed on the anti-wear layer 1 and includes a clamping component and a connecting component. An anti-adhesion film 18 is bonded to the bottom surface of the adhesive layer 4. In this embodiment, the anti-adhesion film 18 can protect the adhesive layer 4, preventing it from adhering to other parts of the repair blanket body during transportation and affecting subsequent use.

[0024] Specifically, the clamping assembly includes two insertion holes 5, located on opposite sides of the wear-resistant layer 1. Each insertion hole 5 contains a rod 6, one end of which is fixedly connected to a fixing rod 7. A sliding groove 8 is provided on the side of the fixing rod 7 closest to the wear-resistant layer 1, within which a sliding block 9 slides. A clamping block 10 is fixedly connected to the side of the sliding block 9 closest to the wear-resistant layer 1. A first tension spring 11 is positioned below the sliding block 9, with one end fixedly connected to the bottom surface of the sliding block 9 and the other end fixedly connected to the bottom inner wall of the sliding groove 8. In this embodiment, the insertion holes 5 and rods 6 allow for disassembly and assembly of the clamping assembly according to usage requirements. The sliding groove 8, sliding block 9, and first tension spring 11 allow the clamping block 10 to be adjusted to different positions, facilitating adaptation to different sizes of repair blanket bodies.

[0025] Specifically, the connecting assembly includes two fixing blocks 19. Each fixing block 19 is fixedly connected to the side wall of its corresponding fixing rod 7. A connecting rod 12 is fixedly connected to one of the opposite sides of each fixing block 19. A limit ring 13 is fixedly connected to the end of each connecting rod 12 away from the fixing block 19. A connecting sleeve 14 is sleeved around the periphery of each connecting rod 12. The same second tension spring 15 is installed inside both connecting sleeves 14. Both ends of the second tension spring 15 are fixedly connected to their respective connecting rods 12. A snap-fit ​​ring 16 is fixedly connected to one end of the connecting sleeve 14 on the right side, and a snap-fit ​​groove 17 is formed at one end of the connecting sleeve 14 on the left side. The snap-fit ​​ring 16 snaps into the snap-fit ​​groove 17. The length of the connecting rod 12 is greater than the length of the corresponding connecting sleeve 14. In this embodiment, the fixing blocks 19, connecting rods 12, connecting sleeves 14, and second tension spring 15 allow the spacing between the two fixing rods 7 to be adjusted according to user needs, thereby adapting to different widths of the repair blanket body.

[0026] The working principle and usage process of this utility model are as follows: During use, the operator rolls up the repair blanket body from the side away from the insertion hole 5. After the roll is completed, the operator moves the clamping block 10 upward. The clamping block 10 drives the sliding block 9 to slide upward in the sliding groove 8, and stretches the first tension spring 11. At this time, the operator moves the two fixing rods 7 away from each other, so that the fixing rods 7 drive the corresponding connecting rods 12 to move through the fixing block 19 and stretch the second tension spring 15. At this time, the distance between the two clamping blocks 10 increases. The operator releases the fixing rods 7, and the stretched second tension spring 15 retracts, causing the connecting rod 12 to move closer to the second tension spring 15. Through the fixing block 19, the fixing rod 7 moves closer to the second tension spring 15, so that the fixing rod 7 is located in the gap at the center of the rolled-up repair blanket body. At this time, the operator releases the clamping block 10, and the stretched first tension spring 11 retracts, causing the sliding block 9 to move downward. The downward movement of the sliding block 9 causes the clamping block 10 to move downward, thereby limiting the rolled-up repair blanket body.

[0027] When personnel need to use the repair blanket to repair the road surface, they first move the two fixing rods 7 away from each other, so that the fixing rods 7 drive the corresponding connecting rods 12 to move through the fixing block 19 and stretch the second tension spring 15. At this time, the distance between the two clamping blocks 10 increases, and the insertion rod 6 moves out of the insertion hole 5, so that the personnel can remove the limiting device. At this time, the personnel peel off the anti-adhesive film 18, apply the adhesive layer 4 to the road surface defect, and roll the anti-wear layer 1 to reinforce the repair blanket. During this process, the anti-wear layer 1 will undergo slight deformation, so that the insertion hole 5 is compacted, avoiding the gaps in the insertion hole 5 from affecting the repair effect.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
