[0019] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.

In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0021] As Figure 1 The utility model discloses a screw storage chain belt, including chain belt body 1, chain belt body 1 is made of flexible plastic, has the bendable characteristic. Multiple storage holes are arranged on chain belt body 1 along its length direction interval, and each storage hole is used to store single screw, and there is a spacing between adjacent storage holes to avoid interference when chain belt body 1 is bent.

[0022] The two ends of chain belt body 1 are respectively provided with front end buckle 2 and rear end clamping groove 3. Front end buckle 2 is the protruding elastic clamping tongue structure, and rear end clamping groove 3 is the recessed slot structure, which is matched with front end buckle 2. When multiple chain belts need to be connected with each other, the front end buckle 2 on the subsequent chain belt body 1 is clamped into the rear end clamping groove 3 on the previous chain belt body 1, and the elastic recovery force generated by the extrusion deformation of the two is used to realize the limiting cooperation, so as to realize the splicing between multiple chain belt bodies 1.

[0023] As Figures 2 to 4As shown, in order to enhance the connection stability of the plurality of chain body 1 after splicing, the chain body 1 is provided with a anti-off device 4. The anti-off device 4 is located on one side of the rear end slot 3 and corresponds to the rear end slot 3. After the front end buckle 2 is buckled into the rear end slot 3, the anti-off device 4 can extrude the front end buckle 2 to prevent the front end buckle 2 from being pulled out of the rear end slot 3. The anti-off device 4 specifically includes an anti-off seat 41, and the anti-off seat 41 is provided with a through hole 411 in the center, which is aligned with the rear end slot 3. The front end buckle 2 passes through the rear end slot 3 and enters the through hole 411. The outer periphery of the anti-off seat 41 is provided with an annular mounting groove 412, and a sealing ring 42 (for example, rubber material) is embedded in the annular mounting groove 412. The inner side of the anti-off seat 41 is provided with a plurality of circumferentially distributed guide grooves 413, and each guide groove 413 is slidably provided with a guide block 43. After the front end buckle 2 is completely buckled into the rear end slot 3, the guide block 43 is pushed to slide along the guide groove 413 to the sealing ring 42, so that the sealing ring 42 is deformed under pressure, and the reaction force generated by the deformation tightly presses the guide block 43 against the outer wall of the front end buckle 2, thereby preventing the front end buckle 2 from being accidentally pulled out and improving the stability of the splicing between the plurality of chain body 1.

[0024] In this embodiment, a guide seat 5 (integrally injection molded) is fixed on one side surface of the chain body 1. The guide seat 5 is provided with a through hole 51, which is coaxially aligned with the receiving hole and is used for the screw rod of the screw to pass through. A plurality of guide holes 52 are provided around the through hole 51 and are uniformly distributed in the circumferential direction of the through hole 51. When the screw is inserted into the receiving hole and the through hole 51, if the insertion direction of the screw does not coincide with the center of the receiving hole, the screw can extrude the guide seat 5 in the circumferential direction (around the through hole 51). The guide holes 52 and the relief openings 53 on the outer periphery of the guide seat 5 in communication with the guide holes 52 can facilitate the deformation of the guide seat 5 around the guide holes 52 under pressure. The elastic force generated by the deformation can guide and correct the insertion direction of the screw, thereby facilitating the storage of the screw.

[0025] In this embodiment, the mounting structure of the sealing ring 42 is that a plurality of embedding grooves 6 are provided on the inner wall of the annular mounting groove 412, and the embedding grooves 6 are uniformly distributed along the circumference of the annular mounting groove 412. Each embedding groove 6 is distributed between adjacent guide blocks 43, and the sealing ring 42 is embedded in the annular mounting groove 412 through the embedding grooves 6, and is fixed by the extrusion deformation of the sealing ring 42;

[0026] In addition, the anti-off seat 41 is provided with a threaded end 414 away from one end of the chain belt body 1, and the threaded end 414 is sleeved with a limiting sleeve 7. The inner wall of the limiting sleeve 7 is provided with an internal thread matched with the threaded end 414, and the limiting sleeve 7 can be axially moved along the threaded end 414 by rotating the limiting sleeve 7. When the limiting sleeve 7 is screwed in the direction of the sealing ring 42, the end portion of the limiting sleeve 7 extrudes the sealing ring 42, and the pressing force of the sealing ring 42 on the guide block 43 is further increased, so that the anti-off effect is enhanced. When the limiting sleeve 7 is reversely rotated, the contact between the inner wall of the limiting sleeve 7 and the outer side of the sealing ring 42 is terminated, so that the pressure can be released, and the front end buckle 2 can be easily pushed out of the rear end buckle groove 3 during disassembly.

[0027] The specific embodiment is only an explanation of the utility model, and is not a limitation of the utility model. Those skilled in the art can make modifications to the embodiment without creative contribution according to the needs after reading the specification, but as long as the modifications are within the scope of the claims of the utility model, they are protected by the patent law.
