Description

Technical Field

[0001] The invention relates to the technical field of automobile maintenance, in particular to a hanging rack for automobile maintenance. Background Art

[0002] Automobile maintenance is the process of technically checking and repairing a broken car, aiming to eliminate the fault and restore the performance and safety standards of the car. Automobile maintenance includes major overhaul and minor overhaul. Major overhaul refers to the repair of restoring the good technical condition of the car and completely (or nearly completely) restoring the life of the car by repairing or replacing any parts (including basic parts) of the car, while minor overhaul refers to the repair of replacing or repairing individual parts to ensure or restore the working ability of the car. When repairing a car engine, it needs to be removed from the interior of the car. When the engine is removed, it needs to be fixed by a lifting device. The current lifting device generally fixes the engine by a steel rope. When the engine is separated from the car, multiple operators are required to support the steel rope. However, the steel rope shakes violently when moving, and the engine is easily collided with the car due to the shaking, resulting in greater problems when the car is repaired. Summary of the invention

[0003] The object of the present invention is to provide a hanging rack for automobile maintenance to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a hanging rack for automobile maintenance, comprising a bearing plate, the bottom of which is provided with a moving component; The movable component includes a hydraulic rod, the top of the hydraulic rod is fixedly connected to the bottom of the carrying plate, the bottom of the hydraulic rod is fixedly connected to a groove rod, the inner wall of the groove rod is fixedly connected to a bent plate, the end of the bent plate away from the groove rod is rotatably connected to a universal wheel, the bottom of the carrying plate is fixedly connected to a stabilizing frame, the bent plate supports the hydraulic rod through the connection between the universal wheel and the groove rod, and when the carrying plate is pushed to move, the carrying plate can be moved to the bottom of the automobile engine through the universal wheel, the lower surface of the stabilizing frame is fixedly connected to a connecting plate, the end of the connecting plate away from the stabilizing frame is fixedly connected to a supporting ring, the bottom of the supporting ring is fixedly connected to a supporting rod, a sliding hole is opened at the bottom of the inner wall of the carrying plate, a supporting component is arranged on the surface of the carrying plate, and a clamping component is arranged on the surface of the carrying plate.

[0005] Furthermore, one end of the connecting plate away from the groove rod extends to the bottom of the groove rod, and there are four connecting plates, which are arranged with the groove rod as the center circumference. The support ring is located below the groove rod, and there are four stabilizing frames, which are arranged with the hydraulic rod as the center circumference. The support ring is supported by four stabilizing frames and the connecting plate, thereby improving the stability of the support ring supporting the load-bearing plate, and one end of the bent plate away from the groove rod extends above the top of the support ring to prevent the bent plate from affecting the up and down movement of the support ring.

[0006] Furthermore, the bottom of the support rod extends to the outer end of the bottom of the support ring, the bottom of the bent plate extends below the bottom of the support ring, and the number of the sliding holes is four, and the four sliding holes are cross-arranged around the hydraulic rod as the center.

[0007] Furthermore, the supporting component includes a contact plate, a sliding rod is fixedly connected to the bottom of the contact plate, a linkage plate is fixedly connected to the bottom of the sliding rod, the end of the linkage plate is fixedly connected to a center frame, the top of the linkage plate is fixedly connected to a spring, and a positioning groove is provided on the surface of the load-bearing plate. There are four positioning grooves, which are located at the four corners of the top of the load-bearing plate. The contact plate will shrink to the inside of the positioning groove after being subjected to the pressure of the automobile engine, so as to avoid the contact plate being stored inside the load-bearing plate and causing the load-bearing plate to become uneven. The inner wall of the center frame is slidably connected to the surface of the hydraulic rod, and the center frame is used to provide limited support for the linkage plate.

[0008] Furthermore, the top of the spring is fixedly connected to the bottom of the supporting plate, the bottom of the sliding rod passes through the supporting plate and extends to the bottom of the supporting plate, the contact plate is located above the supporting plate, the surface of the contact plate is adapted to the inner wall of the positioning groove, and the top of the center frame is in contact with the bottom of the supporting plate.

[0009] Furthermore, the clamping component includes an arc rod, the end of which is fixedly connected to the surface of the linkage plate, an elastic rod is sleeved on the surface of the arc rod, an end of the elastic rod away from the arc rod is hinged with a slide block, and the top of the slide block is fixedly connected to the clamping plate.

[0010] Furthermore, the end of the elastic rod away from the slide block is inclined downward, the top of the slide block extends to the top of the supporting plate through the slide hole, and the end of the elastic rod away from the arc rod moves upward. When the arc rod moves downward, the bottom of the elastic rod will move downward synchronously with the arc rod. At this time, the top of the elastic rod can push the slide block to slide on the inner wall of the slide hole, and the clamping plate is limited by the cooperation between the slide hole and the slide block, thereby improving the stability of the clamping plate during operation.

[0011] Furthermore, the inner wall of the slide block is slidably connected to the inner wall of the slide hole, and the top of the clamping plate extends to above the top of the bearing plate.

[0012] The present invention has the following beneficial effects: The bent plate of the present invention supports the hydraulic rod by connecting the universal wheel and the groove rod. When the load-bearing plate is pushed to move, the load-bearing plate can be moved to the bottom of the automobile engine through the universal wheel. When the automobile engine needs to be supported, the hydraulic rod is driven to push the load-bearing plate to move downward, and the load-bearing plate will push the support ring to move downward through the connection between the stabilizing frame and the connecting plate. When the bottom of the support ring and the support rod are in contact with the ground, the hydraulic rod continues to contract, and the hydraulic rod pushes the universal wheel to separate from the ground through the bent plate, thereby improving the stability of the load-bearing plate when supporting the automobile engine and avoiding displacement of the load-bearing plate when supporting the automobile engine.

[0013] When the bottom of the automobile engine contacts the top of the contact plate, the contact plate pushes the slide bar to slide below the load-bearing plate by gravity. When the slide bar slides downward, the spring is pulled to extend by the linkage plate. At this time, the contact plate uses the elasticity of the spring to support the automobile engine to move slowly downward, thereby preventing the automobile engine from falling too fast and causing damage.

[0014] When the linkage plate of the present invention moves downward, it will push the center frame to slide downward. The center frame is used to limit the linkage plate, thereby improving the stability of the contact plate when moving. When the linkage plate moves downward, the arc rod pushes the elastic rod to move downward. When the elastic rod slides downward, it will push the slide block to slide inside the slide hole. When the slide block moves, it pushes the clamping plate to clamp and fix the automobile engine, thereby further improving the stability of the automobile engine when supported.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] See also Figure 1-Figure 7 As shown, the present invention is a hanging rack for automobile maintenance, comprising a bearing plate 1, and a moving component 2 is arranged at the bottom of the bearing plate 1; The movable component 2 includes a hydraulic rod 10, the top of the hydraulic rod 10 is fixedly connected to the bottom of the supporting plate 1, the bottom of the hydraulic rod 10 is fixedly connected with a groove rod 13, the inner wall of the groove rod 13 is fixedly connected with a bent plate 11, the end of the bent plate 11 away from the groove rod 13 is rotatably connected with a universal wheel 12, the bottom of the supporting plate 1 is fixedly connected with a stabilizing frame 14, the lower surface of the stabilizing frame 14 is fixedly connected with a connecting plate 15, the end of the connecting plate 15 away from the stabilizing frame 14 is fixedly connected with a supporting ring 16, the bottom of the supporting ring 16 is fixedly connected with a supporting rod 17, a sliding hole 18 is opened at the bottom of the inner wall of the supporting plate 1, a supporting component 3 is provided on the surface of the supporting plate 1, and a clamping component 4 is provided on the surface of the supporting plate 1.

[0021] The end of the connecting plate 15 away from the groove rod 13 extends to the bottom of the groove rod 13. The bent plate 11 of the present invention supports the hydraulic rod 10 through the connection between the universal wheel 12 and the groove rod 13. When the load-bearing plate 1 is pushed to move, the load-bearing plate 1 can be moved to the bottom of the automobile engine through the universal wheel 12. When the automobile engine needs to be supported, the hydraulic rod 10 is driven to push the load-bearing plate 1 to move downward, and the load-bearing plate 1 will push the support ring 16 to move downward through the connection between the stabilizing frame 14 and the connecting plate 15. When the bottom of the support ring 16 and the support rod 17 are in contact with the ground, the hydraulic rod 10 continues to contract, and the hydraulic rod 10 will push the universal wheel 12 to separate from the ground through the bent plate 11, thereby improving the stability of the load-bearing plate 1 when supporting the automobile engine and avoiding displacement of the load-bearing plate 1 when supporting the automobile engine. There are four connecting plates 15, and the four connecting plates 15 are arranged with the groove rod 13 as the center circumference, and the support ring 16 is located below the groove rod 13.

In the present invention, when the bottom of the automobile engine contacts the top of the contact plate 20, the contact plate 20 will push the slide bar 22 to slide to the bottom of the supporting plate 1 by gravity. When the slide bar 22 slides downward, the spring 24 is pulled to extend through the linkage plate 25. At this time, the contact plate 20 uses the elasticity of the spring 24 to support the automobile engine to move slowly downward to avoid damage caused by the automobile engine falling too fast. The bottom of the slide bar 22 penetrates the supporting plate 1 and extends to the bottom of the supporting plate 1. The contact plate 20 is located above the supporting plate 1.

When the elastic rod 31 slides downward, it pushes the slide block 32 to slide inside the slide hole 18. When the slide block 32 moves, it pushes the clamping plate 30 to clamp and fix the automobile engine, thereby further improving the stability of the automobile engine when supported. The top of the clamping plate 30 extends above the top of the load-bearing plate 1.

[0028] When in use, the bent plate 11 supports the hydraulic rod 10 through the connection between the universal wheel 12 and the groove rod 13. When the load-bearing plate 1 is pushed to move, the load-bearing plate 1 can be moved to the bottom of the automobile engine through the universal wheel 12. When the automobile engine needs to be supported, the hydraulic rod 10 is driven to push the load-bearing plate 1 to move downward, and the load-bearing plate 1 will push the support ring 16 to move downward through the connection between the stabilizing frame 14 and the connecting plate 15.

At this time, the contact plate 20 uses the elastic support of the spring 24 to slowly move downward to prevent the car engine from falling too fast and causing damage. When the linkage plate 25 moves downward, it will push the center frame 23 to slide downward. The center frame 23 is used to limit the linkage plate 25, thereby improving the stability of the contact plate 20 when moving. When the linkage plate 25 moves downward, it pushes the elastic rod 31 to move downward through the arc rod 33. When the elastic rod 31 slides downward, it pushes the slide block 32 to slide inside the slide hole 18. When the slide block 32 moves, it pushes the clamping plate 30 to clamp and fix the car engine, thereby further improving the stability of the car engine when supported.
