[0002] Nowadays, the increasing population in cities has led to increasing road congestion and parking shortage in cities. This situation has affected traffic flow and the quality of urban life. Traditional ground parking lots can no longer meet the growing number of vehicles. In the field of urban traffic management and parking equipment, the shortage of urban parking spaces, congestion and environmental pollution have attracted widespread attention. In order to effectively utilize limited land space and improve the capacity and efficiency of parking spaces, liftable parking spaces are also popular in the market.

"Although the above structure can realize the lifting and lowering of the vehicle, when the vehicle falls, the loading plate is in direct hard contact with the bottom plate or the ground, which can easily cause the loading plate or the ground to be damaged by collision after long-term use, and direct hard contact will produce a large noise; and after the loading plate falls, the loading plate may have a large moving distance in the left and right direction.

[0004] In order to solve the above problems, we provide a lifting stopper which can buffer and stop the vehicle loading plate from falling and limit the left and right directions of the vehicle loading plate. Utility Model Content

[0016] When the utility model is used, the vehicle loading plate moves up and down, which is the prior art. This application is set based on the vehicle loading plate that can move up and down. The specific up and down movement of the vehicle loading plate is the prior art and will not be described in detail. The vehicle loading plate that can meet the technical solution of this application can be applicable to this technical solution. When the vehicle loading plate moves downward, the bottom of the vehicle loading plate first contacts the rubber gasket above the lifting plate, and the elastic force of the spring 1 under the lifting plate acts as a buffer on the vehicle loading plate, avoiding the bottom of the vehicle loading plate from directly contacting the bottom plate or the ground, causing the vehicle loading plate or the floor to be bumped and damaged, and making a loud noise. A rotatable rotating rod is provided to drive the moving plate to move up and down. The rotating rod is rotated, and the rotating rod and the lifting plate are connected in rotation.

Then change the magnitude of the buffering force of the lifting plate on the vehicle loading plate. A rubber gasket is provided to avoid bumping the vehicle loading plate.

[0017] When the loading plate moves downward, the lifting bucket moves downward, driving the connecting rod to move downward. The connecting rod is a nearly L-shaped structure. When the loading plate is not moving downward, the connecting rod can be rotated outward by its own gravity to avoid interference when the loading plate falls. When the connecting rod moves downward, it is rotated by the force of the limit plate, and the upper end of the connecting rod rotates inward, driving the side pressure plate to squeeze the side of the loading plate. The rubber buffer pad on the side pressure plate fits and squeezes the side of the loading plate to avoid collision with the loading plate and reduce noise. When the loading plate continues to move downward, the rubber buffer pad on the side pressure plate can no longer be squeezed inward, and the limit plate moves outward; the limit plate squeezes spring 2 outward; and the movement interference between the loading plate and the side pressure plate is avoided. Side pressure plates are arranged on the left and right sides of the loading plate to make the loading plate fall to the middle position of the bottom plate when it falls, and at the same time play a certain limiting role on the loading plate, avoiding a large left and right movement of the loading plate. The rotating transmission rod can adjust the squeezing force on the second spring, thereby changing the squeezing force of the side pressure plate on the side of the vehicle loading plate.

[0018] Beneficial effects: The device can achieve a buffering effect on the vehicle loading plate when it falls to the bottom, and slowly stop the vehicle loading plate to prevent the vehicle loading plate from making direct hard contact with the ground or the bottom plate, causing loud noise or bump damage; at the same time, when the vehicle loading plate falls, the side pressure plate can limit the side of the vehicle loading plate to prevent the vehicle loading plate from moving left and right significantly.

[0032] When the utility model is used, the vehicle loading plate 2 moves up and down, which is the prior art. This application is set based on the vehicle loading plate 2 that can move up and down. The specific up and down movement of the vehicle loading plate 2 is the prior art and will not be described in detail. The vehicle loading plate 2 that can meet the technical solution of this application can be applicable to this technical solution. When the vehicle loading plate 2 moves downward, the bottom of the vehicle loading plate 2 first contacts the rubber gasket 9 above the lifting plate 11, and the elastic force of the spring 12 below the lifting plate 11 acts as a buffer for the vehicle loading plate 2, avoiding the bottom of the vehicle loading plate 2 from directly contacting the bottom plate 1 or the ground, causing the vehicle loading plate 2 or the floor to be damaged by collision, making a loud noise, etc. A rotatable rotating rod 18 is provided to drive the moving plate 19 to move up and down.

When the connecting rod 6 moves downward, it is rotated by the force of the limit plate 15. The upper end of the connecting rod 6 rotates inward, driving the side pressure plate 7 to squeeze the side of the vehicle loading plate 2. The rubber buffer pad 8 on the side pressure plate 7 fits and squeezes the side of the vehicle loading plate 2 to avoid collision with the vehicle loading plate 2 and reduce noise. When the vehicle loading plate 2 continues to move downward, the rubber buffer pad 8 on the side pressure plate 7 can no longer be squeezed inward, and the limit plate 15 moves outward; the limit plate 15 squeezes the rotating block 17 outward; and the motion interference between the vehicle loading plate 2 and the side pressure plate 7 is avoided. Side pressure plates 7 are arranged on the left and right sides of the vehicle loading plate 2 to enable the vehicle loading plate 2 to fall to the middle position of the bottom plate 1 when it falls, and at the same time, they play a certain role in limiting the vehicle loading plate 2, thereby preventing the vehicle loading plate 2 from moving left and right significantly.
