Description

Technical Field

[0001] This utility model relates to the field of automotive repair technology, specifically to a support device for automotive repair. Background Technology

[0002] In the automotive repair field, support devices are key equipment for ensuring the safety of repair operations, and are widely used in scenarios such as vehicle lifting, chassis repair, and tire replacement. Their core function is to stably support the vehicle at a specific height, providing a safe operating space for repair personnel. Therefore, the structural stability and locking reliability of the support device are directly related to the safety of the repair process.

[0003] However, the activation of the locking structure of existing traditional support devices relies entirely on manual operation by the user, and the operation is limited to after the support device has lifted the vehicle into position. During the entire process of lifting the vehicle, there is no passive locking structure that can be automatically triggered. Once a problem occurs during the lifting process, the vehicle will lose effective support and fall rapidly. In response to the above problems, the inventors have proposed a support device for automobile repair to solve the above problems. Utility Model Content

[0004] In order to solve the problem of passive locking of support devices for automobile repair, the purpose of this utility model is to provide a support device for automobile repair.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a support device for automobile repair, including a base plate, mounting brackets fixedly connected to both sides of the top of the base plate, movable blocks provided on the inner side of each mounting bracket, support rods fixedly connected to the opposite side of each movable block, a locking mechanism provided at the top of each movable block, the locking mechanism being used to brake the support rods in an emergency, a traction rope fixedly connected to the locking mechanism, hydraulic rods fixedly installed on both sides of the top of the base plate and located inside the mounting brackets, a displacement multiplier mechanism provided at the top of the inner wall of the mounting brackets, and the traction rope wound around the displacement multiplier mechanism.

[0006] Preferably, the locking mechanism includes a fixed frame, which is fixedly connected to the top of the movable block. Two symmetrically distributed sliders are slidably engaged inside the fixed frame. A pin is fixedly connected to one side of each slider facing the other. Two symmetrically distributed vertical plates are fixedly connected to the top of the base plate near the mounting bracket. Equally spaced serrations are fixedly connected to one side of each vertical plate facing the other. The pin is movably inserted between corresponding serrations, and the distance between two adjacent serrations is greater than the height of the pin. A U-shaped frame is provided on the outer side of the fixed frame. One end of the traction rope is fixedly connected to the top of the U-shaped frame. Two guide rods are fixedly connected to the inner side of the U-shaped frame. Guide grooves are provided on each slider. Two vertical grooves corresponding to the guide grooves are provided on both sides of the fixed frame. The guide rods movably pass through the corresponding guide grooves and vertical grooves. A spring is fixedly connected inside the fixed frame and between the two sliders.

[0007] Preferably, the displacement multiplication mechanism includes a fixed pulley, which is fixedly installed at the top of the inner wall of the mounting frame. A movable pulley is fixedly installed on the movable hydraulic rod. The traction rope is sequentially wound around the outside of the fixed pulley and the movable pulley. The end of the traction rope away from the U-shaped frame is fixedly connected to the top of the inner wall of the mounting frame.

[0008] Preferably, two symmetrically distributed sliding rods are fixedly connected between the top of the base plate and the mounting frame, and the moving block is slidably engaged between the outer sides of the two sliding rods.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. During the lifting process of the car, under the action of the car's weight, the U-shaped frame moves upward first. Utilizing the cooperation between the slider, pin, guide groove, vertical groove, U-shaped frame, and guide rod, the two sliders move symmetrically towards each other and compress the spring. When the tension of the traction rope suddenly decreases or disappears, the elastic force of the spring causes the pin to insert between the corresponding two serrations, achieving emergency braking of the car, preventing the car from falling, and further improving the completeness of car maintenance.

[0011] 2. By setting a fixed pulley to change the direction of pulling, and by utilizing the action of a movable pulley, the displacement of the end of the traction rope connected to the moving block is twice the extension and contraction of the movable pulley, thereby reducing the range of the hydraulic rod and further reducing the space occupancy of the equipment.

[0018] 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.

[0019] Example: Figure 1-4 As shown, this utility model provides a support device for automobile repair, including a base plate 1. Mounting brackets 2 are fixedly connected to both sides of the top of the base plate 1. Movable blocks 3 are provided on the inner side of the mounting brackets 2. Support rods 4 are fixedly connected to the opposite side of the movable blocks 3. A locking mechanism 5 is provided at the top of the movable blocks 3. The locking mechanism 5 is used to brake the support rods 4 in an emergency. A traction rope 8 is fixedly connected to the locking mechanism 5. Hydraulic rods 7 are fixedly installed on both sides of the top of the base plate 1 and on the inner side of the mounting brackets 2. A displacement multiplier mechanism 6 is provided at the top of the inner wall of the mounting brackets 2. The traction rope 8 is wound around the displacement multiplier mechanism 6.

[0020] The locking mechanism 5 includes a fixed frame 51, which is fixedly connected to the top of the movable block 3. Two symmetrically distributed sliders 52 are slidably engaged inside the fixed frame 51. A pin 53 is fixedly connected to the opposite side of each slider 52. Two symmetrically distributed vertical plates 54 are fixedly connected to the top of the base plate 1 near the mounting bracket 2. Equally spaced serrations 55 are fixedly connected to the opposite side of each vertical plate 54. The pin 53 is movably inserted between the corresponding two serrations 55.

[0021] By adopting the above technical solution, the pin 53 is inserted between the two corresponding saw teeth 55 to limit the downward movement of the moving block 3, thereby achieving an emergency braking effect.

[0022] A U-shaped frame 58 is provided on the outside of the fixed frame 51. One end of the traction rope 8 is fixedly connected to the top of the U-shaped frame 58. Two guide rods 59 are fixedly connected to the inside of the U-shaped frame 58. Guide grooves 56 are provided on the slider 52. Two vertical grooves 57 corresponding to the guide grooves 56 are provided on both sides of the fixed frame 51. The guide rods 59 can move through the corresponding guide grooves 56 and vertical grooves 57.

[0023] By adopting the above technical solution, during the lifting of the car, under the action of tension, the U-shaped frame 58 and the guide rod 59 are first pulled upward. The vertical groove 57 guides the movement of the guide rod 59, and the cooperation between the guide rod 59 and the guide groove 56 drives the two sliders 52 to move symmetrically to one side, so that the pin 53 is pulled out from between the two serrations 55, releasing the limit on the upward movement of the moving block 3. When the guide rod 59 moves to the limited position, the guide rod 59 and the fixed frame 51 become rigidly in contact. The U-shaped frame 58 continues to be pulled upward, and at the same time, the moving block 3 and the support rod 4 move upward, realizing the lifting operation of the car.

[0024] A spring 510 is fixedly connected inside the fixed frame 51 and between the two sliders 52.

[0025] By adopting the above technical solution, and by setting a spring 510, elastic potential energy is stored when the spring 510 is compressed. When the squeezing force acting on the spring 510 decreases or disappears, the spring 510 is used to reset the pin 53 by elastic deformation.

[0026] The displacement multiplication mechanism 6 includes a fixed pulley 61, which is fixedly installed at the top of the inner wall of the mounting frame 2. A movable pulley 62 is fixedly installed on the movable rod of the hydraulic rod 7. The traction rope 8 is wound around the outside of the fixed pulley 61 and the movable pulley 62 in sequence. The end of the traction rope 8 away from the U-shaped frame 58 is fixedly connected to the top of the inner wall of the mounting frame 2.

[0027] By adopting the above technical solution, when the hydraulic rod 7 extends or retracts, the fixed pulley 61 is used to change the direction of pulling, thereby enabling the support rod 4 to move in the opposite direction to the piston rod of the hydraulic rod 7. At the same time, the movable pulley 62 is used to make the displacement of the end of the traction rope 8 connected to the moving block 3 twice the extension or retraction of the movable pulley 62, thereby reducing the range of the hydraulic rod 7 and further reducing the space occupied by the equipment.

[0028] Two symmetrically distributed sliding rods 9 are fixedly connected between the top of the base plate 1 and the mounting bracket 2, and the moving block 3 is slidably engaged between the outer sides of the two sliding rods 9.

[0029] By adopting the above technical solution and setting the slide bar 9, the vertical movement of the moving block 3 can be guided, thereby improving the stability of the moving block 3 during vertical movement.

[0030] The distance between two adjacent saw teeth 55 is greater than the height of the pin 53.

[0031] By adopting the above technical solution, by setting the distance between two adjacent saw teeth 55 to be greater than the height of the pin 53, the pin 53 can be more easily inserted between the corresponding two saw teeth 55.

[0032] Working principle: When supporting a car during automotive repair, the extension and retraction of the piston rod of the hydraulic rod 7 is used to change the direction of pulling by the fixed pulley 61, thereby making the support rod 4 move in the opposite direction to the movement of the piston rod of the hydraulic rod 7. At the same time, the action of the movable pulley 62 makes the displacement of the end of the traction rope 8 connected to the moving block 3 twice the extension and retraction of the movable pulley 62, thereby reducing the range of the hydraulic rod 7 and further reducing the size of the equipment.

[0033] During the car lifting process, under the action of tension, the U-shaped frame 58 and guide rod 59 are first pulled upward. The vertical groove 57 guides the movement of the guide rod 59, and the cooperation between the guide rod 59 and the guide groove 56 drives the two sliders 52 to move symmetrically to the side that is closer to each other, so that the pin 53 is pulled out from between the two serrations 55 and the spring 510 is compressed, releasing the limit on the upward movement of the moving block 3. When the guide rod 59 moves to the top of the vertical groove 57, the guide rod 59 and the fixed frame 51 become rigidly in contact. The U-shaped frame 58 continues to be pulled upward, and the moving block 3 and the support rod 4 are moved upward at the same time, realizing the car lifting operation.

[0034] During the lifting process, if the traction rope 8 suddenly breaks or the hydraulic rod 7 suddenly depressurizes, the tension acting on the U-shaped frame 58 disappears. Under the elastic force of the spring 510, the pin 53 is reset, so that the pin 53 is inserted between the two corresponding saw teeth 55, thereby achieving emergency braking of the moving block 3, preventing the car from falling, and further improving the safety of the equipment during use.

[0035] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
