Description

Technical Field

[0001] This invention relates to the field of safety support devices for automobile repair, specifically a safety support device for automobile repair. Background Technology

[0002] Currently, with the continuous growth of car ownership, the demand for car repair and maintenance is increasing. During car repair, especially when repairing critical components such as the chassis and engine, it is usually necessary to use specialized support devices to lift and secure the vehicle to provide sufficient operating space and ensure operational safety.

[0003] Existing automotive repair support devices mostly adopt fixed structures or have only limited adjustment functions. Their support height, support angle, and support point position usually cannot be flexibly adjusted according to changes in vehicle model, chassis structure, or body size. This structural limitation means that existing support devices are often only applicable to specific models or a few models, resulting in poor versatility. In practical applications, repair shops need to be equipped with multiple models of support equipment to meet the repair needs of different models, which not only increases equipment investment costs but also reduces repair efficiency.

[0004] Furthermore, due to the inconvenience of adjustment, existing support devices are difficult to provide stable and safe support when dealing with vehicles with complex structures or large differences in chassis height, posing certain safety hazards. Therefore, there is an urgent need for a vehicle maintenance safety support device that can be flexibly adjusted and adapted to various vehicle models to improve the versatility, safety, and efficiency of maintenance operations. Summary of the Invention

[0005] The purpose of this invention is to provide a safety support device for automobile repair, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fixed base, with limiting grooves formed on both sides of the inner side of the fixed base. Two sets of limiting grooves are formed, located at the upper and lower ends of the fixed base respectively. A limiting slider is slidably connected in the limiting groove. An opening and closing screw is connected to the inner side of the limiting slider in the limiting groove at the bottom of the fixed base. The threads on both sides of the opening and closing screw are opposite. A support base is threaded onto the opening and closing screw. A first cylinder is provided on the top of the support base. A first hydraulic rod is inserted into the top of the first cylinder. A support plate is connected to the top of the first hydraulic rod. Recessed grooves are formed at both ends of the support plate.

[0007] Preferably, the two ends of the opening and closing screw are connected to the limiting slider in the limiting groove at the bottom inside the fixed base, the opening and closing screw is threaded to the bottom end of the support base, and an adjustment knob is provided in the middle of the opening and closing screw. Turning the adjustment knob can drive the opening and closing screw to rotate, so that the support base slidably connected on both sides of the opening and closing screw can perform opening and closing movements.

[0008] Preferably, a limiting rod is slidably connected to the top of the support base, and the two ends of the limiting rod are connected to the limiting slider in the limiting groove at the top of the inner side of the fixed seat. The limiting rod limits the support base to prevent it from tilting.

[0009] Preferably, the bottom of the support base is provided with casters around its perimeter, which can assist the support base in sliding left and right and forward and backward.

[0010] Preferably, a second cylinder is provided at the bottom of the recessed groove, a second hydraulic rod is inserted into the top of the second cylinder, and a sealing plate is connected to the top of the second hydraulic rod. The second cylinder can drive the second hydraulic rod to move the sealing plate to extend or retract.

[0011] Preferably, the support plate has a telescopic groove on the inner wall of the top of the recessed groove, and a spring is provided in the telescopic groove. The inner side of the spring is connected to the inner wall of the telescopic groove, and the outer side of the spring is connected to the clamping plate. The spring can drive the clamping plate to extend and retract.

[0012] Preferably, multiple sets of connecting ropes are provided on both sides of the sealing plate, and the other end of the connecting ropes is connected to the outer surface of the clamping plate. When the sealing plate is lowered, the clamping plate can be pulled out of the telescopic groove through the connecting ropes.

[0013] Preferably, the support plate is broken in the middle, and an extension groove is provided at the bottom of the broken end of the support plate. A third cylinder is provided in the extension groove, and an extension support plate is provided on the other side of the broken end. The third cylinder is connected to the extension support plate through a third hydraulic rod. The third cylinder can push the extension support plate to extend from the bottom of the support plate by a certain distance through the third hydraulic rod, thereby extending the support plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention proposes a safety support device for automobile repair. First, according to the left and right wheelbase of the vehicle, an adjustment knob is turned, driving an opening and closing screw. This causes the threaded support base on the screw to open and close according to the vehicle's wheelbase, aligning two sets of support plates parallel to the vehicle's left and right tires. Further, as the support base slides during opening and closing, a limiting rod slidably connected to the top of the support base begins to limit its movement, preventing tilting. Then, according to the vehicle's front and rear wheelbase, a third cylinder at the bottom center of the two support plates is activated. This cylinder, via a third hydraulic rod, pushes an extension support plate outwards from the bottom center, extending the support plate so that the vehicle's front and rear tires are parallel to the recessed grooves on both sides of the support plate. At this time, the limiting sliders connected to both ends of the opening and closing screw and the limiting rod, according to the extension of the support plate, move in the same direction. The car slides along the limiting groove inside the fixed seat, then drives the car onto the support plate along the slope, aligning the car's tires with the recessed grooves on the support plate. The second cylinder is then activated, driving the second hydraulic rod to lower the sealing plate, causing the car's tires to sink into the grooves. Simultaneously, as the sealing plate descends, a clamping plate extends from the telescopic groove via a connecting rope, clamping both sides of the tires to prevent them from swaying in the grooves and enhancing the car's safety on the support plate. Next, the first cylinder at the top of the support base is activated, driving the first hydraulic rod to raise the support plate, lifting and supporting the car. After the car repair is completed, the second cylinder in the groove pushes the sealing plate upwards via the second hydraulic rod until it is parallel to the surface of the support plate. Simultaneously, the spring in the telescopic groove retracts the clamping plate into the telescopic groove, releasing the clamping of the tires. Attached Figure Description

[0018] Please see Figures 1 to 5 This invention provides a technical solution: a fixed base 1, with limiting grooves 2 on both sides of the inner side of the fixed base 1. Two sets of limiting grooves 2 are provided, located at the upper and lower ends of the fixed base 1 respectively. A limiting slider 3 is slidably connected in the limiting grooves 2. An opening and closing screw 4 is connected to the inner side of the limiting slider 3 in the limiting groove 2 at the bottom of the fixed base 1. The threads on both sides of the opening and closing screw 4 are opposite. A support base 7 is threaded onto the opening and closing screw 4. A first cylinder 9 is provided on the top of the support base 7. A first hydraulic rod 10 is inserted into the top of the first cylinder 9. The top of the first hydraulic rod 10 is connected to a support plate 11. The two ends of the support plate 11 are provided with recessed grooves 12. A car is driven onto the support plate 11 along the inclined surface, and the tires of the car are parallel to the recessed grooves 12 on the support plate 11.

[0019] The two ends of the opening and closing screw 4 are connected to the limiting sliders 3 in the limiting grooves 2 at the bottom inside the fixed base 1. The opening and closing screw 4 is inserted into the bottom of the support base 7. An adjustment knob 5 is provided in the middle of the opening and closing screw 4. Turning the adjustment knob 5 can drive the opening and closing screw 4 to rotate, so that the support base 7 connected to the two sides of the opening and closing screw 4 can perform opening and closing movements. The top of the support base 7 is slidably connected to the limiting rod 6. The two ends of the limiting rod 6 are connected to the limiting sliders 3 in the limiting grooves 2 at the top inside the fixed base 1. The limiting rod 6 limits the support base 7 to prevent it from tilting. The limiting rod 6 slidably connected to the top of the support base 7 begins to limit the support base 7 to prevent the support base 7 from tilting.

[0020] The bottom of the support base 7 is provided with casters 8 around its perimeter, which can assist the support base 7 in sliding left and right and forward and backward. The bottom of the recess 12 is provided with a second cylinder 13, and the top of the second cylinder 13 is connected to a second hydraulic rod 14. The top of the second hydraulic rod 14 is connected to a sealing plate 15. The second cylinder 13 can drive the second hydraulic rod 14 to move the sealing plate 15 to extend and retract. The second cylinder 13 in the recess 12 pushes the sealing plate 15 up to be parallel to the surface of the support plate 11 through the second hydraulic rod 14.

[0021] The support plate 11 has a telescopic groove 16 on the inner wall of the top of the recess 12. A spring 17 is installed in the telescopic groove 16. The inner side of the spring 17 is connected to the inner wall of the telescopic groove 16, and the outer side of the spring 17 is connected to the clamping plate 18. The spring 17 can drive the clamping plate 18 to extend and retract. Multiple sets of connecting ropes 19 are provided on both sides of the closing plate 15. The other end of the connecting ropes 19 is connected to the outer surface of the clamping plate 18. When the closing plate 15 descends, the clamping plate 18 can be pulled out of the telescopic groove 16 through the connecting ropes 19. When the closing plate 15 descends, the clamping plate 18 is pulled out of the telescopic groove 16 through the connecting ropes 19 and clamped on both sides of the tire to prevent the tire from swaying left and right in the recess 12.

[0022] The support plate 11 is broken in the middle. An extension groove 20 is provided at the bottom of the broken end of the support plate 11. A third cylinder 21 is provided in the extension groove 20. An extension support plate 23 is provided on the other side of the broken end. The third cylinder 21 is connected to the extension support plate 23 through a third hydraulic rod 22. The third cylinder 21 can push the extension support plate 23 to extend a distance from the bottom of the support plate 11 through the third hydraulic rod 22, thereby extending the support plate 11. The third cylinder 21 at the bottom middle of the support plate 11 pushes the extension support plate 23 to extend a distance from the bottom middle of the support plate 11 through the third hydraulic rod 22, thereby extending the support plate 11, so that the front and rear tires of the car can be parallel to the recessed grooves 12 opened on both sides of the support plate 11.

[0023] In actual use, first, according to the left and right wheelbase of the car, turn the adjustment knob 5 to drive the opening and closing screw 4 to rotate. This causes the support base 7, which is threaded onto the opening and closing screw 4, to open and close according to the left and right wheelbase of the car, making the two sets of support plates 11 parallel to the left and right tires of the car. Further, while the support base 7 is opening and closing, the limiting rod 6, which is slidably connected to the top of the support base 7, begins to limit the movement of the support base 7, preventing it from tilting. Then, according to the front and rear wheelbase of the car, activate the third cylinder 21 at the bottom center of the two sets of support plates 11. This causes the third cylinder 21 to push the extension support plate 23 from the bottom center of the support plate 11 a certain distance via the third hydraulic rod 22, extending the support plate 11 so that the front and rear tires of the car are parallel to the recessed grooves 12 on both sides of the support plate 11. At this time, the limiting sliders 3 connected to both ends of the opening and closing screw 4 and the limiting sliders 3 connected to both ends of the limiting rod 6 slide synchronously in the limiting grooves 2 inside the fixed seat 1 according to the extension of the support plate 11. Then, the car is driven up the slope of the support plate 11, with the car's tires parallel to the grooves 12 on the support plate 11. Next, the second cylinder 13 is activated, driving the second hydraulic rod 14 to lower the sealing plate 15, causing the car's tires to sink into the grooves 12. Simultaneously, as the sealing plate 15 descends, the clamping plate 18 extends from the telescopic groove 16 via the connecting rope 19, clamping both sides of the tire to prevent it from swaying left and right in the grooves 12, thus deepening the grooves. To ensure the safety of the car on the support plate 11, the first cylinder 9 at the top of the support base 7 is activated, causing the first hydraulic rod 10 to lift the support plate 11 and raise the car for support. Furthermore, after the car repair is completed, the second cylinder 13 in the recessed groove 12 pushes the closed plate 15 to rise parallel to the surface of the support plate 11 through the second hydraulic rod 14. At the same time, the spring 17 in the telescopic groove 16 retracts the clamping plate 18 into the telescopic groove 16 through contraction force, releasing the clamping of the tire.
