[0014] 3. Beneficial Effects
[0015] Compared with existing technologies, this utility model provides a self-healing bracelet based on flexible materials, which has the following beneficial effects:
[0016] This self-healing bracelet based on flexible materials works by removing a damaged flexible material ring. Pulling two levers on the damaged ring moves two mounting plates away from the slot box, causing two curved blocks to detach from the slot box. The damaged ring is then removed, and a new ring is passed through the two adjacent rings. The new ring's locking mechanism is then inserted into the slot box, pressing the two curved blocks outwards and against one inner wall of the slot box. The restoring force of the return spring pulls the two curved blocks back into the slot box, fixing the locking mechanism inside. This completes the self-repair process of the bracelet. When a single flexible material ring is damaged, the entire bracelet doesn't need to be discarded; the damaged part can be replaced with just a few simple steps, significantly reducing maintenance costs and extending product lifespan. The bracelet size can be easily adjusted to meet user needs, offering high flexibility and scalability. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0024] Example:
[0025] Please see Figures 1-4 A self-healing bracelet based on flexible materials includes: multiple flexible material rings 1, which cooperate with each other; two ends of each flexible material ring 1 are fixedly connected to a locking block 2 and a locking slot box 3, respectively; the locking block 2 is slidably embedded in the inside of the locking slot box 3; side connecting boxes 4 are fixedly connected to both outer surfaces of the locking slot box 3; arc-shaped blocks 5 slide through both inner walls of the locking slot box 3; mounting plates 6 are fixedly connected to one outer surface of each arc-shaped block 5; four return springs 7 are fixedly connected between each mounting plate 6 and the corresponding side connecting box 4; and pull rods 9 are fixedly connected to one outer surface of each mounting plate 6, with each pull rod 9 sliding through the corresponding side connecting box 4.
[0026] In a specific embodiment of this utility model, multiple flexible material rings 1 are nested in pairs to form a wearable bracelet. The flexible material rings 1 are mainly made of flexible material. The locking block 2 is held in place by two arc-shaped blocks 5 inside the slot box 3, making the flexible material ring 1 self-closed into a ring. When one of the flexible material rings 1 that makes up the bracelet is damaged, the two pull rods 9 on this flexible material ring 1 are pulled, causing the two mounting plates 6 to move away from the slot box 3. The two arc-shaped blocks 5 disengage from the inside of the slot box 3, the locking block 2 is removed from the slot box 3, the damaged flexible material ring 1 is removed, and then a new flexible material ring 1 is passed through the corresponding two adjacent flexible material rings 1. The new flexible material ring 1 has a locking block 2 inserted into the slot box 3. The locking block 2 presses the two arc-shaped blocks 5 outward and then fits against the inner wall of one side of the slot box 3. Then, under the restoring force of the return spring 7, the two mounting plates 6 drive the two arc-shaped blocks 5 back into the slot box 3, so that the locking block 2 is fixed inside the slot box 3. This completes the self-repairing work of the bracelet composed of multiple flexible material rings 1. When a flexible material ring 1 in the bracelet is damaged, the entire bracelet does not need to be scrapped. The damaged part can be replaced with just a few simple steps, which greatly reduces the maintenance cost and improves the service life of the product. The size of the bracelet can be easily adjusted according to the user's needs, with strong flexibility and expandability.

[0037] Working principle: Multiple flexible material rings 1 are nested in pairs to form a wearable bracelet. The flexible material rings 1 are mainly made of flexible material. The locking block 2 is held in place by two curved blocks 5 inside the slot box 3, making the flexible material ring 1 self-closed into a ring. When one of the flexible material rings 1 that makes up the bracelet is damaged, pulling the two levers 9 on this flexible material ring 1 moves the two mounting plates 6 away from the slot box 3. The two curved blocks 5 disengage from the inside of the slot box 3, removing the locking block 2 from the slot box 3 and removing the damaged flexible material ring 1. Then, a new flexible material ring 1 is passed through the corresponding two adjacent flexible material rings 1. The locking block 2 of the material ring 1 is inserted into the slot box 3. The locking block 2 presses the two arc-shaped blocks 5 outward and then fits against the inner wall of one side of the slot box 3. Then, under the restoring force of the return spring 7, the two mounting plates 6 drive the two arc-shaped blocks 5 back into the slot box 3, so that the locking block 2 is fixed inside the slot box 3, thereby completing the self-repair work of the bracelet composed of multiple flexible material rings 1. When a flexible material ring 1 in the bracelet is damaged, the entire bracelet does not need to be scrapped. The damaged part can be replaced with just a few simple steps, which greatly reduces the maintenance cost and improves the service life of the product. The size of the bracelet can be easily adjusted according to the user's needs, with strong flexibility and expandability.
