Description

Technical Field

[0001] The utility model relates to the technical field of lifting platforms, in particular to a leveling stabilizing mechanism. Background Art

[0002] The lifting platform is mainly used to lift goods to the required height for shipment. In order to improve the utilization rate of the site, most manufacturers or individuals choose multi-story buildings. Therefore, a lifting platform is also needed to facilitate the lifting or lowering of goods. In order to fix the lifting platform on the corresponding floor, a leveling stabilization mechanism is required.

[0003] In the prior art, many lifting platforms do not use a leveling limit structure. Therefore, when the cargo is too heavy, there will be a certain height difference between the lifting platform and the docking layer. In serious cases, the platform may sink excessively, causing safety hazards. Therefore, it is necessary to propose a leveling stabilization mechanism to solve the above-mentioned problems. Utility Model Content

[0006] The rear sides of the two cams are movably connected with a linkage trigger rod through two movable shafts, and a driving mechanism is arranged on the right side of the linkage trigger rod.

[0007] In order to facilitate the driving of the linkage trigger rod to move, as a preferred leveling stabilization mechanism of the utility model, the driving mechanism includes a connecting seat fixedly connected to the right end of the linkage trigger rod, the rear side of the connecting seat is movably connected to a connecting block through a movable shaft, the front end surface of the movable platform is movably connected to a cylinder through a hinge, and the output end of the cylinder is fixedly connected to the connecting block.

[0008] In order to improve the stability of the two groups of first guide seats and the two groups of second guide seats, as a preferred leveling stabilization mechanism of the utility model, the two groups of the first guide seats and the two groups of the second guide seats are respectively welded to the front side of the movable table.

[0009] In order to improve the stability of the two first limit seats and the two second limit seats, as a preferred leveling stabilization mechanism of the utility model, the two first limit seats and the two second limit seats are respectively welded to the front sides of the two fixed tabletops.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The driving mechanism drives the linkage trigger rod to move, thereby driving the two cams to rotate counterclockwise, and then the two first telescopic arms and the two second telescopic arms can enter the two first limit seats and the two second limit seats respectively, so that the movable platform can be locked at the floor where it needs to be docked. Moreover, since the two first telescopic arms and the two second telescopic arms are respectively positioned by three points, their stability and reliability are higher. At the same time, the structure is simple, the failure rate is low and it is easy to maintain, which further achieves the purpose of eliminating the safety hazard caused by excessive sinking of the movable platform due to excessive weight of goods.

At the same time, the structure is simple, the failure rate is low and it is easy to maintain, which further achieves the purpose of eliminating the safety hazard caused by excessive sinking of the movable platform 1 due to excessive weight of the goods.

[0021] As a technical optimization solution of the utility model, the driving mechanism includes a connecting seat 15 fixedly connected to the right end of the linkage trigger rod 16, the rear side of the connecting seat 15 is movably connected to the connecting block 14 through a movable shaft, the front end surface of the movable platform 1 is movably connected to the cylinder 13 through a hinge 12, and the output end of the cylinder 13 is fixedly connected to the connecting block 14.
