Description

Technical Field

[0001] This utility model relates to the field of safety hook technology, and more specifically, to a self-locking multi-safety safety hook. Background Technology

[0002] Safety hooks are important connecting tools commonly used in fire protection, engineering, construction, and crane industries to ensure the safe connection of people or objects. They are mostly made of stainless steel, alloy steel, or aluminum alloy.

[0003] In many regions, the use of fall protection is both a basic requirement and a legal mandate. Typically, a fall protection system involves fastening workers with safety belts or harnesses and connecting them to a fixed object using ropes, cables, belts, or safety hooks. A typical safety hook is used by first engaging the lock on top of the hook, then holding the closing bar, and finally rotating the main hook. Once the main hook is rotated to the appropriate angle, the rope is placed inside. After the rope is secured, the main hook is released, and the locking mechanism on top of the hook locks the rope in place. However, this method is cumbersome and inconvenient, necessitating modification and optimization. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a self-locking multi-safety hook, which has the advantages of being convenient and easy to disassemble.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-locking multi-safety hook, comprising a top block and a main hook, wherein the main hook is fixedly disposed below the top block;

[0006] One end of the main hook is hinged to a closing rod. A housing is fixedly installed between the two sides inside the main hook. A side plate is fixedly installed on the top of the housing. A fixing plate is fixedly installed on the top of the housing. A spring is fixedly connected to one side inside the housing. A handle is fixedly installed at one end of the spring. A baffle is movably installed between the two sides inside the housing. A sliding rod is fixedly installed on one side of the baffle. One end of the sliding rod passes through the fixing plate, the handle, and the left and right sides of the housing. The handle and the sliding rod are fixedly sleeved together. A gear is fixedly sleeved inside the closing rod. A toothed block is fixedly installed on the other side of the baffle. One end of the toothed block passes through the left and right sides of the side plate and meshes with the gear.

[0007] As a preferred embodiment of this utility model, a top plate is movably installed above the top block, the bottom of the top plate extends into the interior of the top block, a fixing block is fixedly installed on the side of the top block, a knob is rotatably installed inside the fixing block, a threaded rod is rotatably installed on one side of the fixing block, one end of the threaded rod passes through the knob, the fixing block, the limiting rod and the left and right sides of the threaded rod in succession, the threaded rod is threadedly connected to the knob, a limiting plate is fixedly installed on one end of the threaded rod, a limiting rod is fixedly installed on one side of the limiting plate, and one end of the limiting rod passes through the left and right sides of the top block.

[0008] As a preferred embodiment of this utility model, a hook ring is fixedly installed above the top plate, and the hook ring is located above the top block.

[0009] As a preferred embodiment of this utility model, one end of the closing rod is movably connected to one end of the main hook, and the closing rod is located below the top plate.

[0010] As a preferred embodiment of this utility model, one end of the handle extends to the outside of the main hook, and the side of the handle is movably connected to the main hook.

[0011] In a preferred embodiment of this invention, the threaded rod is movably connected to the fixed block, the threaded rod and the top block, and the limiting rod is movably connected to the top block.

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

[0013] 1. This utility model involves pushing the closing rod to rotate clockwise. Due to the design of the gear and toothed block, the gear rotates and drives the toothed block to move downward, which in turn causes the sliding rod and spring to move backward. When the closing rod is rotated to the appropriate position, the spring drives the toothed block to move forward and mesh with the gear to fix the gear. Then, the rope is placed on the main hook, and the handle is pulled backward, which drives the sliding rod and toothed block to move backward. After rotating the closing rod to the appropriate position and releasing the handle, the spring once again drives the toothed block to move forward and fix the gear. Compared with traditional devices, this device, through the design of the toothed block and gear, makes it more convenient to place the rope, reduces the number of operation steps, improves the ease of operation, and thus improves the working efficiency of the device.

[0014] 2. This utility model, by rotating the knob, causes the threaded rod and the limiting rod to move backward because the knob is threadedly connected to the threaded rod, until one end of the threaded rod is completely removed from the inside of the top plate. At this point, the top plate can be moved upward and the top block can be disassembled. Compared with traditional devices, this device can replace the hook ring in time when it is damaged by disassembling the top block and the top plate, reducing the cost of using the device, improving the utilization rate of the top block and the main hook, and increasing the service life.

[0023] 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.

[0024] like Figures 1 to 7 As shown, this utility model provides a self-locking multi-safety hook, including a top block 1 and a main hook 2, with the main hook 2 fixedly disposed below the top block 1;

[0025] One end of the main hook 2 is hinged to a closing rod 3. A housing 7 is fixedly installed between the two sides inside the main hook 2. A side plate 6 is fixedly installed on the top of the housing 7. A fixing plate 8 is fixedly installed on the top of the housing 7. A spring 9 is fixedly connected to one side inside the housing 7. A handle 10 is fixedly installed at one end of the spring 9. A baffle 19 is movably installed between the two sides inside the housing 7. A slide rod 11 is fixedly installed on one side of the baffle 19. One end of the slide rod 11 passes through the fixing plate 8, the handle 10 and the left and right sides of the housing 7. The handle 10 and the slide rod 11 are fixedly sleeved. A gear 13 is fixedly sleeved inside the closing rod 3. A toothed block 12 is fixedly installed on the other side of the baffle 19. One end of the toothed block 12 passes through the left and right sides of the side plate 6 and meshes with the gear 13.

[0026] When the operator uses the device, they first push the closing lever 3 clockwise around the connection point between the closing lever 3 and the main hook 2. Due to the design of the gear 13 and the toothed block 12, the gear 13 rotates, causing the toothed block 12 to move downwards, which in turn causes the sliding rod 11 to move backwards. At the same time, the spring 9 is also compressed. When the closing lever 3 is rotated to the appropriate position, the spring 9 will drive the toothed block 12 to move forward and engage with the gear 13, thus fixing the gear 13. Then, the rope is placed above the main hook 2, and the handle 10 is pulled backwards. When the handle 10 moves backwards, it will drive the sliding rod 11 to move backwards, which in turn causes the toothed block 12 to move backwards. After rotating the closing lever 3 counterclockwise to the appropriate position, the handle 10 is released, and the spring 9 will again drive the toothed block 12 forwards to fix the gear 13.

[0027] By pushing the closing rod 3 to rotate clockwise, the design of gear 13 and toothed block 12 causes gear 13 to rotate and drive toothed block 12 to move downward, thereby causing slide rod 11 and spring 9 to move backward. When the closing rod 3 is rotated to the appropriate position, spring 9 drives toothed block 12 to move forward and mesh with gear 13 to fix gear 13. Then, the rope is placed on the main hook 2, and the handle 10 is pulled backward, which drives slide rod 11 and toothed block 12 to move backward. After rotating the closing rod 3 to the appropriate position, the handle 10 is released, and spring 9 drives toothed block 12 to move forward again to fix gear 13. Compared with the traditional device, this device, through the design of toothed block 12 and gear 13, makes it more convenient to place the rope, reduces the number of operation steps, improves the ease of operation, and thus improves the working efficiency of the device.

[0028] A top plate 4 is movably installed above the top block 1, and the bottom of the top plate 4 extends into the interior of the top block 1. A fixing block 14 is fixedly installed on the side of the top block 1. A knob 15 is rotatably installed inside the fixing block 14. A threaded rod 16 is rotatably installed on one side of the fixing block 14. One end of the threaded rod 16 passes through the knob 15, the fixing block 14, the limiting rod 18, and the left and right sides of the threaded rod 16. The threaded rod 16 is threadedly connected to the knob 15. A limiting plate 17 is fixedly installed on one end of the threaded rod 16. A limiting rod 18 is fixedly installed on one side of the limiting plate 17. One end of the limiting rod 18 passes through the left and right sides of the top block 1.

[0029] When the operator uses the device, they first turn the knob 15. When the knob 15 is turned, because there is a thread at the connection between the knob 15 and the threaded rod 16, the rotation of the knob 15 will cause the threaded rod 16 to move backward. When the threaded rod 16 moves backward, the limiting rod 18 will also move backward. When the threaded rod 16 moves, one end of the threaded rod 16 will gradually move out of the interior of the top plate 4. When one end of the threaded rod 16 is completely moved out of the interior of the top plate 4, the top plate 4 can be moved upward and the top plate 4 can be disassembled from the top block 1.

[0030] By rotating knob 15, which is threadedly connected to threaded rod 16, threaded rod 16 and limit rod 18 are moved backward until one end of threaded rod 16 is completely removed from the top plate 4. At this point, top plate 4 can be moved upward and disassembled from top block 1. Compared with traditional devices, this device can replace hook ring 5 in time when it is damaged by disassembling top block 1 and top plate 4, reducing the cost of device use, improving the utilization rate of top block 1 and main hook 2, and increasing service life.

[0031] A hook 5 is fixedly installed above the top plate 4, and the hook 5 is located above the top block 1.

[0032] The design of the hook 5 allows the device to be hung up with a rope, making it easy to use.

[0033] One end of the closing rod 3 is movably connected to one end of the main hook 2, and the closing rod 3 is located below the top plate 4.

[0034] The design of the closed rod 3 makes it difficult for the rope to move out of the main hook 2 when it is hung above the main hook 2.

[0035] One end of the handle 10 extends to the outside of the main hook 2, and the side of the handle 10 is movably connected to the main hook 2.

[0036] The handle 10 allows for easy movement of the toothed block 12, thereby enabling the closing rod 3 and gear 13 to rotate.

[0037] Among them, the threaded rod 16 is movably connected to the fixed block 14, the threaded rod 16 and the top block 1, and the limiting rod 18 is movably connected to the top block 1.

[0038] The threaded rod 16 is movably connected to the fixed block 14 and the top block 1, so that the threaded rod 16 can fix the position of the top plate 4.

[0039] Working principle and usage process of this utility model:

[0040] When the operator uses the device, they first push the closing lever 3 clockwise around the connection point between the closing lever 3 and the main hook 2. Due to the design of the gear 13 and the toothed block 12, the gear 13 rotates, causing the toothed block 12 to move downwards, which in turn causes the sliding rod 11 to move backwards. At the same time, the spring 9 is also compressed. When the closing lever 3 is rotated to the appropriate position, the spring 9 will drive the toothed block 12 to move forward and engage with the gear 13, thus fixing the gear 13. Then, the rope is placed above the main hook 2, and the handle 10 is pulled backwards. When the handle 10 moves backwards, it will drive the sliding rod 11 to move backwards, which in turn causes the toothed block 12 to move backwards. After rotating the closing lever 3 counterclockwise to the appropriate position, the handle 10 is released, and the spring 9 will again drive the toothed block 12 forwards to fix the gear 13.

[0041] When the operator uses the device, they first turn the knob 15. When the knob 15 is turned, because there is a thread at the connection between the knob 15 and the threaded rod 16, the rotation of the knob 15 will cause the threaded rod 16 to move backward. When the threaded rod 16 moves backward, the limiting rod 18 will also move backward. When the threaded rod 16 moves, one end of the threaded rod 16 will gradually move out of the interior of the top plate 4. When one end of the threaded rod 16 is completely moved out of the interior of the top plate 4, the top plate 4 can be moved upward and the top plate 4 can be disassembled from the top block 1.
