Description

Technical Field

[0001] This utility model relates to the field of seat belt device technology, specifically a high-strength polypropylene fiber integrated lock seat belt with a locking mechanism. Background Technology

[0002] Seat belts are safety components used on equipment. They are used to ensure safety when riding in aircraft or performing high-altitude work or stunts. The main raw materials are polyester, polypropylene, and nylon. Seat belts are not just webbing; they are assembled from other parts in addition to webbing. The ideal working process of a seat belt is as follows: First, it tightens immediately, pressing the person into the seat without hesitation at the first moment of an accident. Then, it loosens appropriately, waiting for the peak impact force to pass or for the person to be protected by the airbag before loosening the seat belt.

[0003] For high-altitude operations, most safety belts simply bind the workers at height, with the various parts of the belt securing the body through knots or wrapping. The length of the belt is mostly fixed and cannot be effectively adjusted. Therefore, during use, situations often arise where the safety belt affects operation or is too short for the worker to stretch, which poses a significant safety hazard for high-altitude operations. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength polypropylene fiber integrated lock safety belt with a locking mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength polypropylene fiber integrated lock safety belt with a locking mechanism, comprising an outer shell, a cover plate mounted on the surface of the outer shell, and a release port on the side of the outer shell. A rotating column is mounted on the surface of the release port, a recessed layer is provided at one end of the rotating column, and an extension end is mounted inside the recessed layer. A return spring is mounted on the surface of the extension end, a void layer is provided at the front end of the other side of the rotating column, and a front end is installed on the surface of the rotating column. A locking post is mounted on the surface of the front end.

[0006] Preferably, an engagement disc is provided at the extended end close to the surface of the recessed layer, and a polypropylene safety belt is fitted on the surface of the rotating column.

[0007] Preferably, the upper end of the front end is provided with a through hole, and a pressing column is mounted on the through hole, and a pressing plate is mounted on the surface of the pressing column.

[0008] Preferably, a locking block is assembled at the lower end of the pressing column, and an embedded block is assembled on the surface of the locking block, and a bearing plate is assembled on the surface of the locking block.

[0009] Preferably, a spacer plate is installed on the surface of the bearing plate, and a tension spring is installed in the middle of the spacer plate. The spacer plate is welded to the inner surface of the outer shell.

[0010] Preferably, a limiting block is installed at the bottom of the vacant layer, and a front top block is installed at the upper end of the limiting block, and an engagement plate is installed at the corresponding position of the locking block.

[0011] Preferably, the outer housing has surface-mounted connecting bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Compared to other safety belts, this device is equipped with a locking mechanism on the safety belt. The locking mechanism can ensure that the safety belt, which is made of polypropylene filament, is locked in place. In some working scenarios, this ensures the stability of the safety belt and prevents it from falling off or slipping. This locking mechanism prevents the safety belt from being released by locking the central rotating post inside, thus ensuring its safety.

[0014] 2. This device is simple and reliable in design. By connecting and binding several devices, the appropriate length can be fitted onto the user's body. Each part is bound to a specific position on the human body surface by the release of the internal polypropylene safety belt. It is quite convenient to operate and use, and the subsequent replenishment or replacement of the polypropylene belt is also straightforward. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution:

[0023] refer to Figure 1 , 2 The main body is an outer shell 1, which is designed in a hexagonal shape. A cover plate 2 is installed on the surface of the outer shell 1, which seals the middle space of the outer shell 1 to prevent damage to the interior due to collisions or other reasons during use. The outer shell 1 has four release ports on its side, which occupy the four sides of the hexagon and are designed in pairs opposite each other. A rotating column 6 is installed on the surface of the release port. The length of the rotating column 6 extends beyond the release port at both ends, and the extended part extends to other positions. An inner part is provided at one end of one side of the rotating column 6. The recessed layer is equipped with an extension end, and a return spring 7 is installed on the surface of the extension end. The return spring 7 provides a retraction effect after the polypropylene safety belt 3 is released by utilizing its own pull-back effect. The other front end of the rotating column 6 is provided with an empty layer, and a front end 17 is installed on the surface of the rotating column 6. A locking post 16 is installed on the surface of the front end 17. The number of locking posts 16 is designed to be six, and the end faces of adjacent posts are in the same position. During assembly, the locking posts 16 are staggered and their rotation does not affect each other.

[0024] refer to Figure 3 , 4The main body is an extension end, and an engagement disc 8 is provided on the extension end close to the surface of the recessed layer. The engagement disc 8 is made of a material with a low coefficient of friction, and the engagement disc 8 away from the rotating column 6 is fixed to the recessed layer. One end of the return spring 7 is fixed to the engagement disc 8 on this side, and the other side rotates with it. Due to the low friction, its rotation will not affect the release effect of the rotating column 6. A polypropylene safety belt 3 is fitted on the surface of the rotating column 6, and one end of the polypropylene safety belt 3 is fixed to the rotating column 6. The upper end of the front end 17 has a through hole, and a pressing column is fitted on the through hole. 9. A pressing plate 4 is assembled on the surface of the pressing column 9. An adsorption ring is assembled at the lower end of the pressing plate 4. The pressing plate 4 is made of magnetic material. The surface of the adsorption ring is provided with magnetic material so that the pressing plate 4 can be adsorbed when pressed down. A locking block 12 is assembled at the lower end of the pressing column 9. An embedded block 18 is assembled on the surface of the locking block 12. An embedded block 18 is provided on both sides. The embedded blocks 18 are of different sizes and positions. They are mainly used to be inserted between the locking columns 16 for locking to ensure that the front end 17 is locked. A bearing plate 11 is assembled on the surface of the locking block 12.

[0025] refer to Figure 5 The main body is a support plate 11. A partition plate is installed on the surface of the support plate 11, and a tension spring 10 is installed in the middle of the partition plate. The upper partition plate is welded to the inner surface of the outer shell 1. The tension spring 10 is used to pull the pressing plate 4 back to its original position after it is pulled out of the surface of the adsorption ring. A limiting block 14 is installed at the bottom of the empty layer, and a front top block 15 is installed at the upper end of the limiting block 14. A meshing plate 13 is installed at the corresponding position of the locking block 12. The limiting block 14 and the other components installed at the bottom of the locking block 12 mainly restrict the locking block 12 to prevent the locking block 12 from falling too far and causing the inner block 18 to get stuck at the bottom of the meshing column. A connecting bolt 5 is installed on the surface of the outer shell 1 for connecting other devices.

[0026] In actual use, several devices are first connected by connecting bolts 5. Then, the polypropylene safety belt 3 is stretched outward according to different positions and tied to the worker's body until it is long enough. Then it is released. The internal return spring 7 is used to make the rotating column 6 rotate. The polypropylene safety belt 3 automatically retracts and adheres to the body surface. After the belt is fully tightened, the pressing plate 4 is pressed down. The internal pressing column 9 descends and the locking block 12 descends. Since the locking block 12 is designed along the gap at the front end 17 on both sides, the embedded block 18 on the surface descends one after another to lock the meshing column on both sides until the meshing plate 13 reaches the surface of the front top block 15. At this time, the pressing plate 4 is also attracted to the surface of the suction ring, completing the locking effect of the safety belt.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
