Description

Technical Field

[0001] The invention relates to the technical field of trailer hooks, in particular to a trailer hook which is easy to disassemble. Background Art

[0002] Trailer hooks are mainly installed on ordinary household vehicles and self-propelled RVs. With trailer hooks installed, small trailers and trailer RVs can be towed. Of course, some rear bicycle racks and luggage boxes can also be installed to increase the vehicle's cargo space, allowing people who like self-driving tours to take their families, friends and luggage to picnic and camp in nature during holidays. How pleasant it is.

[0003] However, existing trailer hooks are fixed to the vehicle body by screws. When the trailer hook is not needed, the vehicle owner cannot remove the trailer hook by himself. At the same time, the trailer hook exposed outside the vehicle body causes troubles to the vehicle owner and the following vehicle when the motorcycle is driving. For example, in the event of a rear-end collision, unnecessary disputes may easily arise due to the trailer hook. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a trailer hook that is easy to disassemble, thereby solving the problem that a trailer hook fixedly installed on a vehicle body is difficult to disassemble.

[0005] Technical Solution

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a trailer hook that is easy to disassemble, comprising a mounting base, a chassis is arranged inside the mounting base, the chassis is fixedly mounted to the inside of the mounting base by screws, a turntable is arranged inside the chassis, the turntable is movably connected to the inside of the chassis by a rotating shaft, a fixing block is embedded inside the chassis, first clamping blocks are movably installed at both ends of the fixing block, a first spring is fixedly installed between the two first clamping blocks, a disc is fixedly installed on the right side of the fixing block, a rotating drum is movably installed inside the disc, a baffle is fixedly installed inside the rotating drum, a second spring is fixedly installed on the baffle, and the second spring is away from the baffle. A second clamping block is fixedly installed on one end of the rotating drum, a sleeve is provided on the outer periphery of the rotating drum, and a trailer hook is fixedly installed on the right side of the sleeve, a first side plate is fixedly installed on the side of the mounting base, a first steering block is fixedly installed on the right side of the first side plate, a third spring is fixedly installed on the inner wall of the top of the first steering block, and a third clamping block is fixedly installed on one end of the third spring away from the inner wall of the top of the first steering block, an axle rod passes through the interior of the first steering block, the first steering block is movably connected to the second steering block through the axle rod, a second side plate is fixedly installed on the right side of the second steering block, a pulley is movably installed inside the second side plate, a connecting rod is provided on the right side of the pulley, and a cover plate is provided on the connecting rod.

[0007] Furthermore, the front ends of the first clamping block and the third clamping block are both quadrangular pyramids.

[0008] Furthermore, a rectangular groove matched with the fixing block is provided on the front surface of the chassis, and a fixing clamping plate matched with the trailer hook is provided on the top of the chassis.

[0009] Furthermore, a slot adapted to the trailer hook is provided on the front surface of the disc.

[0010] Furthermore, the interior of the disc is a hollow ring, and fixing grooves adapted to the second clamping block are provided on the disc at the positions of three o'clock, six o'clock, nine o'clock and twelve o'clock.

[0011] Furthermore, the first side plate, the second side plate and the cover plate are filled with buffer blocks, and the buffer blocks are in the shape of hexagonal columns.

[0012] Furthermore, a T-shaped handle is fixedly mounted on the front surface of the cover plate.

[0013] Furthermore, the chassis is provided with mounting grooves adapted for screws, the number of the screws is not less than four, and gaskets are provided under the screws.

[0014] Furthermore, the second steering block is provided with a quadrangular pyramid-shaped groove matched with the third clamping block.

[0015] Furthermore, a slide groove matching the pulley and the cover plate is provided inside the second side plate.

[0016] Working principle: When in use, lift the cover plate through the T-shaped handle, push the cover plate into the slide groove set inside the second side plate through the sliding of the pulley, remove the trailer hook from the fixed clamping plate, rotate the trailer hook through the sleeve until it is perpendicular to the disc, rotate the trailer hook clockwise, and drive the rotating drum set inside the disc to rotate clockwise through the rotation of the trailer hook. During the rotation, the second clamping block keeps squeezing the second spring due to the squeezing of the inner wall of the disc. After the rotating drum rotates clockwise to the twelve o'clock position inside the disc, The second spring pushes the second clamping block into the fixing groove provided on the disc. Since the clamping groove provided on the front surface of the disc restricts the trailer hook, the trailer hook will not rotate. After using the trailer hook, the trailer hook is rotated from the twelve o'clock position to the three o'clock position again, and then the trailer hook is rotated upward to fix the trailer hook in the fixing clamping plate. In case of a rear-end collision, the trailer hook will not cause serious damage to the rear vehicle due to its exposure to the outside, causing unnecessary disputes. If the trailer hook needs to be removed, the trailer hook is moved along the vertical direction of the chassis. The first spring is pressed inwardly in the direction of the first side plate, and the fixing block is affected by the thrust, and the fixing block slides in the slot. The first block presses the first spring inwardly during the sliding process. After the fixing block is pushed into the slot set in the turntable, the trailer hook is rotated so that the fixing block and the rectangular slot opened on the chassis are in the same plane, and then the fixing block is pulled out outward, which not only facilitates the removal of the trailer hook, but also facilitates the installation of the trailer hook. When the trailer hook is subjected to an impact force perpendicular to the cover plate or perpendicular to the second side plate, the buffer block filled in the cover plate, the first side plate and the second side plate will absorb the impact force first, and the remaining impact force after being absorbed by the buffer block will be transmitted forward. Under the action of the impact force, the second side plate is displaced to the left relative to the position of the first side plate, and the second steering block is driven to move at the same time. With the movement of the second steering block, the third block is separated from the quadrangular pyramid groove, so that the first side plate and the second side plate are rotated through the shaft rod. Through the absorption of the buffer block and the rotation between the first side plate and the second side plate, the risk of the trailer hook being separated from the vehicle body due to the impact and damaging the vehicle body is reduced.

[0017] Beneficial Effects

[0018] 1. The trailer hook that is easy to disassemble is driven by the cooperation among the chassis, the turntable, the fixed block, the first clamping block, the first spring and the trailer hook. The fixed block is pushed into the turntable by pushing the trailer hook, and the trailer hook is rotated to the rectangular groove provided on the chassis. The trailer hook can be disassembled by pulling the trailer hook outward, which not only facilitates the disassembly of the trailer hook, but also facilitates the installation of the trailer hook.

[0019] 2. The trailer hook that is easy to disassemble is used by the cooperation among the disc, sleeve, rotating drum, trailer hook and fixed clamping plate. When in use, the clamping groove on the disc can fix the trailer hook, so that the trailer hook will not swing left and right when in use. When the trailer hook is not in use, the trailer hook is fixed in the fixed clamping plate. In the event of a rear-end collision, the trailer hook will not cause serious damage to the rear vehicle due to its exposure to the outside, causing unnecessary disputes.

[0020] 3. The trailer hook which is easy to disassemble reduces the damage to the vehicle body caused by the impact force through the coordination among the first side plate, the second side plate, the first steering block, the second steering block, the shaft rod and the buffer block, and through the absorption of the impact force by the buffer block and the consumption of the impact force by the rotation between the side plates.

Several buffer blocks 26 are spliced ​​together to form a honeycomb-like structure, which is more stable and has improved strength, and can effectively cope with larger impact forces. When in use, the cover plate 25 is lifted by the T-shaped handle 29, and the cover plate 25 is pushed into the slide groove set inside the second side plate 22 through the sliding of the pulley 23, and the trailer hook 15 is removed from the fixed clamping plate 28, and the trailer hook 15 is rotated by the sleeve 14 until it is perpendicular to the disc 9, and the trailer hook 15 is rotated clockwise.The rotation of the trailer hook 15 drives the rotating drum 10 disposed inside the disc 9 to rotate clockwise. During the rotation process, the second clamping block 13 keeps squeezing the second spring 12 due to the squeezing of the inner wall of the disc 9. After the rotating drum 10 rotates clockwise to the twelve o'clock position inside the disc 9, the second spring 12 pushes the second clamping block 13 into the fixed groove disposed on the disc 9. Since the clamping groove disposed on the front surface of the disc 9 restricts the trailer hook 15, the trailer hook 15 will not rotate. After the trailer hook 15 is used, the trailer hook 15 is moved again. After rotating from the twelve o'clock position to the three o'clock position, the trailer hook 15 is rotated upward to fix the trailer hook 15 in the fixing clamping plate 28. If a rear-end collision occurs, the trailer hook 15 will not cause serious damage to the rear vehicle due to its exposure to the outside, causing unnecessary disputes.

The fixing block 6 is affected by the thrust and slides in the card slot. The first card block 7 presses the first spring 8 inward during the sliding process. When the fixing block 6 is removed, the fixing block 6 is pushed inward along the direction perpendicular to the chassis 2. After the fixing block 6 is pushed into the slot set in the turntable 4, the trailer hook 15 is rotated so that the fixing block 6 and the rectangular slot opened on the chassis 2 are in the same plane, and then the fixing block 6 is pulled outward, which not only facilitates the removal of the trailer hook 15, but also facilitates the installation of the trailer hook 15. When the trailer hook 15 is subjected to an impact force perpendicular to the cover plate 25 or perpendicular to the second side plate 22, the buffer block 26 filled in the cover plate 25, the first side plate 16 and the second side plate 22 will absorb the impact force first, and the remaining impact force after being absorbed by the buffer block 26 The impact force is transmitted forward. Under the action of the impact force, the second side plate 22 is displaced to the left relative to the first side plate 16, and the second steering block 21 is driven to move. With the movement of the second steering block 21, the third clamping block 19 is disengaged from the quadrangular pyramid groove 30, so that the first side plate 16 and the second side plate 22 rotate through the shaft 20. Through the absorption of the buffer block 26 and the rotation between the first side plate 16 and the second side plate 22, the risk of the trailer hook 15 being separated from the vehicle body due to the impact and causing damage to the vehicle body is reduced.
