Description

Technical Field

[0001] This invention relates to the field of construction safety protection technology, and in particular to a non-detachable safety belt hook. Background Technology

[0002] When carrying out construction or renovation work, workers must wear safety belts and connect them to scaffolding when working on the outside of the building to prevent safety risks such as accidental falls during high-altitude operations.

[0003] Currently, safety belt hooks used in the market require workers to attach one end of the hook to their waist safety belt and the other end to the scaffold pole. Because existing hooks cannot directly pass through the junctions between poles, workers must first unhook the hook when changing work areas and then go around the junction to re-hook it. However, when unhooking, the safety belt loses its protective function because the hook is not connected to the scaffold pole. If an accident occurs at this time due to other factors, the consequences could be disastrous. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a non-detachable seat belt hook that can solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a non-detachable seat belt hook, comprising a ring capable of opening and closing, the ring being composed of a sliding rod and a fixed ring, the sliding rod being composed of a spring-limiting bushing, a remote rod hinge point shaft, a remote rod, and a buckle. The remote rod is connected to the ring via the remote rod hinge point shaft, the buckle is located at the tail end of the remote rod, the middle part of the remote rod is connected to the fixed ring by a connecting rod, the other ring is the same as the original ring, one end of the sliding rod and the fixed ring are fixedly connected to a connecting block, the outer walls of the original ring and the other ring are rotatably connected to a fixed bushing, the ring on the fixed bushing can rotate freely relative to the connecting block, a connecting rod is fixedly connected to the surface of the ring, the surface of the connecting rod is respectively fixedly mounted on the sliding rod and the fixed ring.

[0006] Preferably, the fixed bushing is fixed to the connecting block, the handle is located in the middle of the connecting block, and each of the two diagonal sides of the handle is connected to the fixed bushing by a separate spring.

[0007] Preferably, the handle is fastened inside the connecting block, and the spring limiting bushing passes through the limiting groove via the spring and the handle, and is fixed inside the connecting block by the fixing bushing.

[0008] Preferably, the connecting block has a built-in moving mechanism, which consists of a spring and a handle, located inside the connecting block. The moving mechanism can be moved within the connecting block via the handle, thereby rotating the connecting rod.

[0009] Preferably, the connecting block has a built-in follower mechanism, which consists of a spring-limiting bushing and a limiting groove, located inside the connecting block. The surface of the spring-limiting bushing and the inner wall of the limiting groove are slidably connected. The follower mechanism is nested on the moving mechanism, and the translation of the handle drives the spring-limiting bushing.

[0010] Preferably, the connecting rod is fixed by two connecting rod hinge points, which are located on the rocker arm and the fixed ring, respectively. When the connecting rod moves, it drives the rocker arm to rotate around the rocker arm hinge point through the connecting rod hinge point.

[0011] Preferably, a seat belt hole is provided at the lower part of the handle, through which the seat belt passes to connect the seat belt and the hook, and the seat belt hole at the lower part of the handle is located on the outside of the entire hook.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This non-detachable safety belt hook, through the setting of the moving mechanism, can prevent the hook from falling off by passing through the three-way crossbar and cross shaft, avoiding the drawbacks of traditional safety belts, and can maximize the protection of workers' construction safety. At the same time, this invention can be applied to T-shaped bars and cross-shaped bars, making the device applicable to a wider range of scaffolding and improving the applicability of the device.

[0014] 2. This non-detachable safety belt hook, through the design of locking blocks and slots, allows the fixing ring and sliding rod to be separated. Simultaneously, the two rings only need to be inserted into the connecting block to complete the overall connection, reducing the assembly difficulty of the internal structure of the device, facilitating the assembly of the internal structure by workers, and thus improving the efficiency of the overall assembly of the device, thereby increasing the production efficiency of the device. Furthermore, this invention has a simple structure and reasonable design, and has high promotional value.

[0015] 3. This non-detachable safety belt hook, through the setting of the moving mechanism, ensures that two rings are locked during the movement of the device. During the crossing of the pole, at least one ring is always locked, thereby achieving the characteristic of closed-loop connection with the scaffolding body throughout the entire process. This can effectively prevent the hook from detaching from the scaffolding under unintentional conditions, further ensuring the safety of workers and improving the safety of the device.

Detailed Implementation

[0024] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0025] Example 1:

[0026] Please see Figure 1-5 This invention provides a technical solution: a non-detachable seat belt hook, including a ring 1 that can be opened and closed. The ring 1 is composed of a slide rod 10 and a fixed ring 11. One end of the slide rod 10 and the fixed ring 11 is fixedly connected to a connecting block 2. The inner walls of the ring 1 and another ring 12 are rotatably connected to a fixed bushing 6. The ring 1 and the other ring 12 on the fixed bushing 6 can rotate freely relative to the connecting block 2, ensuring the flexibility of the relative position of the ring 1 and the other ring 12, thereby making it more convenient and faster to pass the hook over the bar.

[0027] The connecting block 2 has a follower mechanism for the hook inside. The follower mechanism consists of a spring limiting bushing 10-1 and a limiting groove 11-1. The surface of the spring limiting bushing 10-1 and the inner wall of the limiting groove 11-1 are slidably connected. When the slide rod 10 or the fixed ring 11 rotates, the side wall of the limiting groove 11-1 restricts the rotation of the ring 1 and the other ring 12, thus preventing the ring 1 and the other ring 12 from deviating to the side. When the slide rod 10 and the fixed ring 11 move relative to each other, one side of the slide rod 10 will be pushed out, and the opening and closing process is realized by using the remote hinge point shaft 10-2 and the connecting rod 5.

[0028] A connecting rod 5 is fixedly connected to the surfaces of ring 1 and another ring 12. The connecting rod 5 is fixed by two connecting rod hinge shafts 8, which are located on rocker arm 10-3 and fixed ring 11, respectively. When the connecting rod 5 moves, it drives rocker arm 10-3 to rotate around rocker arm hinge shaft 10-2 through the connecting rod hinge shafts 8. When slide bar 10 is pushed out, the connecting rod 5 fixed on fixed ring 11 has a pulling effect, pulling the connecting rod 5 fixed on rocker arm 10-3, causing rocker arm 10-3 to pull down, thereby opening ring 1 or the other ring 12.

[0029] Inside the connecting block 2 is a moving mechanism consisting of a spring 4 and a handle 3, nested within the follower mechanism. The handle 3 can move horizontally within the connecting block 2, thereby moving the slide rod 10 horizontally. During movement, the handle controls the movement of ring 1 and the other ring 12 in two directions, respectively. When the handle 3 is pushed forward, one side of the slide rod 10 pushes forward, opening ring 1 while the other ring 12 remains closed. After opening the rings, the handle 3 automatically returns to the center position due to the spring force of the spring 4, at which point both ring 1 and the other ring 12 are closed, completing the ring closure process. To open the other ring 12, simply push the handle 3 in the opposite direction.

[0030] The side of the ring 1 is another connection point between the slide rod 10 and the fixed ring 11, which is formed by a buckle 10-4 and a groove 11-2. When the handle 3 is in the center position, the buckle 10-4 and the groove 11-2 are tightly engaged, ensuring that the ring 1 is locked and ensuring safety. When the handle 3 is shifted to one side, the hinge point 10-2 of the remote lever on this side rotates, and the remote lever 10-3 is pulled down, causing the buckle 10-4 and the groove 11-2 to separate, thus opening the ring.

[0031] Furthermore, in actual use, when a worker passes through the cross axis, the hook is transferred from the X+ axis to the X- axis. At this point, the user can directly move the handle 3, which in turn rotates the connecting rod 5, causing the connecting rod 5 to retract the remote rod 10-3, thereby opening one side of the ring 1. The ring 1 is then hooked onto the X- axis along the open section, and the handle 3 is released to return it to the center position, causing the ring 1 to close automatically. The handle 3 is then moved in the opposite direction to open the other ring 12, which is then hooked onto the X- axis in the same way. Throughout this process, it is ensured that at least one of the rings, ring 1 and ring 12, remains attached to the cross bar while moving from one axis to the other. Similarly, when a worker passes through the three-way cross axis, i.e., the T-shaped area, the same operation can be performed. Through the design of the moving mechanism, the hook can pass through the three-way cross bar and the cross axis without falling off, avoiding the drawbacks of traditional safety belts and maximizing worker safety.

[0032] This invention is applicable to T-shaped and cross-shaped poles, expanding its applicability. Furthermore, its simple structure and reasonable design make it highly valuable for widespread adoption. Secondly, the fixed bushing 6 allows the device to increase its operating space by rotating ring 1 or another ring 12, enabling unobstructed passage through the scaffold frame throughout the entire process. This effectively prevents unintentional hook detachment from the scaffold, further ensuring worker safety and improving the overall safety of the device.

[0033] Example 2:

[0034] Assembly of the entire hook: The entire hook body consists of two rings and a connecting block.

[0035] Ring 1 and another ring 12 are composed of a sliding rod 10 and a fixed ring 11. The fixed ring 11 serves to fix the hook, and the opening, closing, and hooking / unhooking of the hook are achieved through the sliding rod 10. The remote rod 10-3 is connected to the sliding rod 10 through the remote rod hinge shaft 10-2. The buckle 10-4 is located at the tail end of the remote rod 10-3. The function of the sliding rod 10 is achieved by the mortise and tenon structure of the slot 11-2 and the buckle 10-4. The connecting rod hinge shaft 8 is located in the middle of the remote rod 10-3 and is connected to the fixed ring 11 through the connecting rod 5, assisting in the function of the sliding rod 10. Ring 1 and another ring 12 are connected by a fixed bushing 6 and fixed to the connecting block 2. The connecting block 2 consists of a spring 4 and a handle 3. The handle 3 is located in the middle of the connecting block 2. Each diagonal side of the handle 3 is connected to the fixed bushing 6 by a separate spring 4 to drive the sliding rod 10. At spring 4, spring 4 is maintained in its basic shape by spring limiting bushing 10-1 and limiting groove 11-1. When handle 3 is pushed, one side of spring 4 is compressed and the other side of spring 4 is stretched. The different states of the two springs 4 affect the opening and closing of slide rod 10, so that ring 1 and another ring 12 open and close at the same time. This ensures that the hook can pass through the connected object without obstruction throughout the process, effectively reducing the possibility of the hook detaching from the connected object in case of accidents, thus ensuring the safety of the operator and improving the safety guarantee when using the hook. A safety belt hole 9 is provided at the lower part of handle 3. When the operator uses the hook, the safety belt 7 can be directly passed through the safety belt hole 9 to connect the safety belt 7 to the hook. The safety belt hole 9 at the lower part of handle 3 is located on the outside of the entire hook and will not interfere with the function of slide rod 10. This ensures that when the operator uses the hook to pass through the rod, the safety belt 7 and the rod will not get tangled together, making it convenient for the operator to use. The entire hook assembly is a single piece. The operator connects the lower parts of the ring 1 and another ring 12 directly to the connecting block 2, and the handle 3 is fastened inside the connecting block 2. The spring limiting bushing 10-1 passes through the limiting groove 11-1 via the spring 4 and the handle 3, and is fixed inside the connecting block 2 by the fixing bushing 6. This reduces the assembly difficulty of the internal structure of the device, facilitates the assembly of the internal structure of the device by the workers, and thus improves the efficiency of the workers in assembling the entire device, thereby improving the production efficiency of the device.

[0036] Working Principle: In actual use, when a worker passes through the cross shaft, the hook is transferred from the X+ axis to the X- axis. At this time, the user can directly move the handle 3, which will drive the connecting rod 5 to rotate, causing the connecting rod 5 to retract the remote rod 10-3, thereby opening one of the rings 1. The ring 1 is then hooked onto the X- axis along the opened section. The handle 3 is then released, returning the ring to the center position, and the ring 1 automatically closes. The handle 3 is then moved in the opposite direction to open the other ring 12, which is then hooked onto the X- axis in the same way. Throughout this process, it is ensured that at least one of the rings 1 and 12 does not detach from the cross bar, allowing movement from one axis to any other axis. Similarly, when a worker passes through a three-way cross shaft, i.e., a T-shaped area, the same operation can be performed. During the transfer, the two rings can be rotated to increase their relative position, improving the flexibility of passing through the bar. Thus, through the setting of the moving mechanism, the hook can pass through various types of bars and shafts such as three-way cross shafts and cross shafts without detaching.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
