Technical Field

[0001] The utility model relates to the technical field of automobile maintenance, in particular to a vehicle teaching and training platform for automobile maintenance. Background Art

[0002] An automobile engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine can be applied to both power generation devices and the entire machine including the power device.

[0003] In the existing engine teaching and training platform, the engine cannot be conveniently installed during use, and its position is difficult to adjust, which reduces the convenience and stability of equipment installation.

[0004] For example, an engine teaching and training platform disclosed in Chinese patent CN216697556U is provided with an adjustable positioning component, in which the positioning device clamps and fixes the engine, thereby improving the convenience and stability of engine installation and fixation, reducing damage to the engine, and increasing the service life of the equipment. At the same time, a pushing cylinder is provided to push an X-shaped support frame to adjust the height of the engine, thereby improving the teaching quality and ensuring students' viewing experience.

[0005] However, the bottom of the teaching and training platform is supported only by the universal wheels at the bottom, and the engine is heavy, and the universal wheels are easily damaged if supported by the universal wheels for a long time.

[0006] For this reason, we urgently need to provide a vehicle teaching and training platform for automobile maintenance that can prevent the universal wheel from being damaged by excessive squeezing. Utility Model Content

[0007] The purpose of the utility model is to provide a vehicle teaching and training platform for automobile maintenance, so as to solve the problem that the bottom end of the teaching and training platform proposed in the above background technology is supported only by the universal wheels at the bottom end, while the engine is heavy and the universal wheels are easily damaged if supported by the universal wheels for a long time.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vehicle teaching and training platform for automobile maintenance, comprising a base frame and a support rod, wherein the support rod is fixedly connected to the left and right ends of the upper front and rear sides of the base frame, and the upper and lower ends of the base frame are connected with a display mechanism, and the display mechanism comprises a support unit and a fixing unit, wherein the support unit is arranged at the upper and lower ends of the base frame, and the fixing unit is arranged at the upper end of the base frame.

[0009] The support unit includes a first threaded rod, a first handle, a universal wheel and a support seat, the first threaded rod is connected to the four inner corners of the base frame, the first handle is fixedly connected to the upper end of the first threaded rod, the universal wheel is fixedly connected to the lower end of the first threaded rod, and the support seat is fixedly connected to the lower side of the base frame.

[0010] A further improvement is that first threaded holes are provided at the four corners of the base frame, and the outer side of the first threaded rod is threadedly connected to the inner side of the first threaded hole, so that when the first handle is turned to drive the first threaded rod in the first threaded hole to rotate, the first threaded rod can move relative to the base frame.

[0011] A further improvement is that rectangular grooves are provided at the four corners of the support seat, the universal wheels are located in the rectangular grooves at the four corners of the support seat, and the height of the support seat is less than that of the support seat. Therefore, after the training platform is moved to the desired position through the universal wheels at the bottom, the first handle is turned to drive the first threaded rod to rotate in the first threaded hole while moving upward, driving the universal wheels at the lower end to move to the rectangular grooves at the four corners of the support seat, so that the training platform as a whole can be supported by the bottom side of the support seat contacting the ground, thereby protecting the universal wheels.

[0012] A further improvement is that the fixing unit includes a bottom rod, a second threaded rod, a second handle, a splint and a reinforcement rod, the bottom rod being fixedly connected to the lower side of the two support rods at the front and rear ends, the second threaded rod being connected to the inside of the support rod, the second handle being fixedly connected to the end of the second threaded rod away from the bottom rod, the splint being fixedly connected to the end of the second threaded rod away from the second handle, and the reinforcement rod being fixedly connected to the left and right ends of the upper side of the base frame.

[0013] A further improvement is that a second threaded hole is provided inside the support rod at the middle position above the bottom rod, and the outer side of the second threaded rod is threadedly connected to the inner side of the second threaded hole. Therefore, after placing the automobile engine on the bottom rod, the second handle is turned to drive the second threaded rod located in the second threaded hole to rotate, and the clamping plate moves toward the automobile engine until the clamping plate moves to the front and rear sides of the left and right ends of the engine, and then the engine can be fixed to the upper end of the bottom rod, so that engines of different sizes can be fixed on the training platform for maintenance and display.

[0014] A further improvement is that one end of the reinforcement rod away from the chassis is fixedly connected to the outer side of the bottom rod, so that the bottom rod can more firmly support and fix the engine thereon through the support of the reinforcement rod.

[0015] A further improvement is that a rubber pad is fixedly connected to one side of the clamping plate away from the second threaded rod, so that after the clamping plate is moved to the front and rear sides of the engine, the rubber pad on the outside of the clamping plate contacts the front and rear sides of the engine, so that the engine can be clamped and fixed more firmly.

[0016] In summary, the present application discloses a vehicle teaching and training platform for automobile maintenance.

[0017] According to the technical solution, after the training platform is moved to the desired position through the universal wheels at the bottom, the first handle is rotated to drive the first threaded rod to rotate in the first threaded hole and move upward at the same time, thereby driving the universal wheels at the lower end to move to the rectangular grooves at the four corners of the support seat, so that the training platform as a whole can be supported by the bottom side of the support seat contacting the ground, thereby protecting the universal wheels.

[0018] Furthermore, after placing the automobile engine on the bottom rod, the second handle is turned to drive the second threaded rod in the second threaded hole to rotate, so that the clamping plate moves toward the automobile engine until the clamping plate moves to the front and rear sides of the left and right ends of the engine. Then, the engine can be fixed to the upper end of the bottom rod, so that engines of different sizes can be fixed on the training table for maintenance display. BRIEF DESCRIPTION OF THE DRAWINGS
