[0053] Working principle: When the lifting platform needs to be stored after use, the hydraulic push rod 313 is started by the external controller, so that the telescopic rod of the hydraulic push rod 313 begins to extend, and the overall length of the hydraulic push rod 313 increases, which can push the two rotating shafts 35 to move synchronously in the direction away from each other. Under the action of the first support rod 34, the height of the rotating shaft 35 can be continuously reduced, and under the action of the second support rod 36, the top plate 1 can be driven to descend, and the top plate 1 drives the limiting slide plate 310 to slide inside the limiting slide groove 311 during the descent process until the load-bearing plate 315 slides into the interior of the box body 2;

[0054] During this process, when there is a car on the top plate 1 to store the lifting platform, the gravity of the car is applied to the bottom plate 31 through the top plate 1, the load-bearing plate 315, the second support rod 36, the rotating shaft 35 and the first support rod 34, so that the bottom plate 31 squeezes the fourth spring 52, and after the spring is compressed, the surface of the bottom plate 31 and the electromagnet plate 51 fit together. At this time, whether the car is rising or falling, the bottom plate 31 and the electromagnet plate 51 fit together under the action of the gravity of the car. When the bottom plate 31 is in the process of moving and fitting with the electromagnet plate 51, the movement of the bottom plate 31 drives the two bending plates 54 to move downward synchronously, and the movement of the bending plate 54 drives the T-shaped slider 511 to move , the movement of the T-shaped slider 511 drives the fourth side plate 512 and the third optical axis 513 to move downward synchronously. Since the third optical axis 513 is inserted into the middle slot 514, the tilting rod 59 is rotated between the two fifth side plates 515 in the direction away from the T-shaped slider 511. The rotation of the tilting rod 59 drives the second optical axis 58 to move, thereby pulling the U-shaped positioning plate 56 to move in the direction away from the limiting slide plate 310 until the bottom plate 31 and the electromagnet plate 51 are fitted, so that one end of the U-shaped positioning plate 56 moves to the inside of the positioning slot 57. At this time, the telescopic rod of the limiting slide slot 311 is extended, so that the bearing plate 315 directly slides into the inside of the box body 2;

[0055] When there is no car on the top plate 1, that is, after the lifting platform lifts the car to a certain height, the position of the car has been fixed. When the lifting platform needs to fall without load, due to the lack of gravity on the top plate 1, the bottom plate 31 moves in the direction away from the electromagnet plate 51 under the action of the fourth spring 52, and the movement of the bottom plate 31 drives the two bending plates 54 to move upward. The movement of the bending plates 54 drives the T-shaped slider 511 and the third optical axis 513 to move upward, thereby causing the tilting rod 59 to rotate in the direction close to the T-shaped slider 511. The rotation of the tilting rod 59 applies a force to the U-shaped positioning plate 56 through the second optical axis 58, so that the U-shaped positioning plate 56 fits one side of the limiting slide plate 310. Since the height of the rectangular positioning groove 55 is higher than the height of the U-shaped positioning plate 56, in the process of the top plate 1 driving the limiting slide plate 310 to move downward, the U-shaped positioning plate 56 can slide into the rectangular positioning groove 55 at the corresponding position, thereby temporarily fixing the position of the limiting slide plate 310. , at this time, the lifting platform can be moved out from the bottom of the car. If the top plate 1 is to be lowered again, the electromagnet plate 51 is started by the external controller, so that the electromagnet plate 51 is energized and operated. Since a uniform magnetic field is formed inside the electromagnet plate 51 after being energized, and the bottom plate 31 is made of iron material, the magnetic field generated by the electromagnet plate 51 adsorbs the bottom plate 31 so that the surfaces of the bottom plate 31 and the electromagnet plate 51 fit together, and compresses the fourth spring 52. At this time, the movement of the bottom plate 31 drives the bending plate 54 to move downward, thereby causing the U-shaped positioning plate 56 to slide out from the inside of the rectangular positioning groove 55. By starting the hydraulic push rod 313 again, the hydraulic push rod 313 can be made to continue to extend, so that the bearing plate 315 slides into the inside of the box body 2. By adding a heavy object to the top plate 1, the bearing plate 315 can also slide into the inside of the box body 2. When the bearing plate 315 slides into the inside of the box body 2, the lifting platform can be stored and can also be carried.

[0056] When the lifting platform drives the car to rise, the hydraulic push rod 313 is started by the external controller, so that the telescopic rod of the hydraulic push rod 313 retracts, and the two rotating shafts 35 are driven to move to realize the lifting of the car. At this time, the bottom plate 31 provides support for the car, and the bottom plate 31 and the electromagnet plate 51 are in contact. When the hydraulic push rod 313 fails and causes the car to fall suddenly, the force applied by the car to the bottom plate 31 at this time is rapidly reduced. Under the action of the fourth spring 52, the bottom plate 31 rises rapidly, and then drives the two bending plates 54 to move upward, so that the tilting rod 59 drives the U-shaped positioning plate 56 to move in the direction close to the limit slide plate 310, and the end of the U-shaped positioning plate 56 is close to the limit slide plate 310. The positioning plate 310 has a suitable force. When the U-shaped positioning plate 56 slides into the interior of the rectangular positioning groove 55, the position of the limiting plate 310 is fixed. At this time, the car supported by the top plate 1 stops descending after a rapid descent. This is beneficial for when the hydraulic push rod 313 fails and causes the car to fall suddenly. After the force acting on the bottom plate 31 by the car is rapidly reduced, it rises rapidly under the action of the fourth spring 52, driving the movement of related components, so that the U-shaped positioning plate 56 is inserted into the rectangular positioning groove 55 of the corresponding height to achieve the effect of fixing its position, thereby preventing the car from continuing to descend, improving the safety of the lifting platform during use, and effectively avoiding serious accidents such as car falling caused by equipment failure;

[0057] When the telescopic end of the hydraulic push rod 313 is extended to make the top plate 1 fall, the top plate 1 and the bearing plate 315 move downward synchronously, and the movement of the bearing plate 315 drives the third side plate 412 to move, thereby driving the rectangular rod 43 to move. When the end of the rectangular rod 43 moves to the position of the associated card block 418, the associated card block 418 is inserted into the inside of the card slot 47 as the rectangular rod 43 moves. In the process of inserting the associated card block 418 into the card slot 47, a force is applied to the isosceles trapezoidal card block 48, so that the side plug plate 414 slides inside the side slot 49, thereby making the second The spring 411 is stretched, and under the action of the elastic potential energy of the second spring 411, the isosceles trapezoidal block 48 is inserted into the isosceles trapezoidal groove 417, and the top of the associated block 418 is fitted with the inner wall of the card slot 47. At this time, the rectangular rod 43 continues to move, driving the associated block 418 to move downward synchronously. The movement of the associated block 418 drives the rectangular frame 421 to move. Under the action of the first optical axis 422 and the inclined setting of the inclined through slot 420, the transverse square rod 419 moves transversely inside the transverse plug-in slot 426. The transverse square rod 419 The movement of the second right-angled trapezoidal block 416 drives the movement, so that the bottom surface of the second right-angled trapezoidal block 416 slides on the upper surface of the first right-angled trapezoidal block 415, until the second right-angled trapezoidal block 416 slides out from the surface of the first right-angled trapezoidal block 415, moves downward in the rectangular frame 421, and under the action of the elastic potential energy of the third spring 423, the longitudinal rod 424 can be driven to move downward, thereby driving the U-shaped bracket 427 to slide inside the storage slide groove 429. With the movement of the U-shaped bracket 427, when the roller 428 is in contact with the ground, the box body 2 can be moved away from the ground. The lifting platform 310 is moved in the direction of the vehicle, and after the lifting platform 310 is moved to a suitable position on the box body 2, the hydraulic push rod 313 stops running, and the box body 2 is fixed at a certain height under the support of the rectangular rod 43 on the U-shaped bracket 427. The lifting platform 310 can be easily pushed to move under the action of the four rollers 428, so that the lifting platform can be easily moved to the bottom of the car, which is conducive to the rollers 428 supporting the lifting platform when the bearing plate 315 slides into the interior of the box body 2. The lifting platform can be easily pushed to move under the action of the rollers 428 by applying a force to the box body 2;

[0058] When the telescopic end of the hydraulic push rod 313 retracts to make the top plate 1 rise and lift the car, the top plate 1 drives the supporting plate 315 to rise synchronously, and then drives the rectangular rod 43 to move upward synchronously. Since the box body 2 is not in contact with the ground, the gravity of the box body 2, the top plate 1 and the supporting plate 315 makes the associated block 418 fit the rectangular rod 43 and move synchronously. In this process, the longitudinal rod 424 drives the second right-angled trapezoidal block 416 to move upward through the transverse square rod 419, and the second right-angled trapezoidal block 416 does not contact the first right-angled trapezoidal block 415. When the roller 428 slides into the interior of the storage slide groove 429, as the rectangular rod 43 continues to move upward, and under the action of the elastic potential energy of the third spring 423, the second right-angled trapezoidal block 416 moves toward the first right-angled trapezoidal block 415. The second right-angled trapezoidal block 415 moves in the direction of the right-angled trapezoidal block 415. When the upper surface of the second right-angled trapezoidal block 416 fits with the bottom surface of the first right-angled trapezoidal block 415, as the rectangular rod 43 moves, under the action of the elastic potential energy of the second spring 411, the isosceles trapezoidal block 48 slides out from the inside of the isosceles trapezoidal groove 417. At this time, the rectangular rod 43 continues to move upward with the bearing plate 315. Under the support of the first right-angled trapezoidal block 415 on the second right-angled trapezoidal block 416, the position of the horizontal square rod 419 can be fixed, and then the position of the rectangular frame 421 can be fixed, and then the roller 428 is located inside the storage chute 429. In the process of lifting the car, the bottom surface of the box body 2 is in direct contact with the ground, ensuring the stability of the lifting platform when lifting the car.

[0059] When the lifting platform needs to be carried, before the top plate 1 and the carrying plate 315 move downward, a downward force is applied to the rectangular rod 43. Due to the restriction of the third side plate 412, the positions of the end shaft 413 and the built-in square slide bar 45 do not change, and during the movement of the rectangular rod 43, the built-in square slide bar 45 slides inside the built-in square slide groove 46 to squeeze the first spring 44 until the rectangular rod 43 slides out from the inside of the second storage groove 42, and after the rectangular rod 43 moves to a suitable position, a horizontal force is applied to the rectangular rod 43, so that the rectangular rod 43 rotates around the end shaft 413 as the axis. When the rectangular rod 43 is in a horizontal position, the force applied to the rectangular rod 43 is stopped, and the elastic potential energy of the first spring 44 is used. The rectangular rod 43 is used to slide on the surface of the built-in square slide rod 45, and the end of the rectangular rod 43 away from the rectangular plate 410 is close to the bottom surface of the supporting plate 315, so that the rectangular rod 43 cannot rotate in the opposite direction, and the rectangular plate 410 is now located inside the first storage groove 41, and the top plate 1 and the supporting plate 315 move downward. Since the rectangular rod 43 is in a horizontal state, it will not squeeze the associated block 418. When the top plate 1 and the supporting plate 315 move to the lowest position, the U-shaped bracket 427 cannot be moved. At this time, the lifting platform is supported by the bottom surface of the box body 2, which is beneficial for supporting the lifting platform with the bottom surface of the box body 2 when the lifting platform is carried and transported, thereby ensuring the stability of the lifting platform during the carrying and transportation process.
