Detailed Description

As shown in the figure, the leveling device of the lifting platform comprises a driving mechanism 102 installed at the lower end of the lifting platform 101, wherein the driving mechanism 102 is used for driving a push rod 103 to do transverse linear motion. The lower end of the lifting platform 101 is also provided with a plurality of guide rings 104 for the push rod 103 to pass through, thereby ensuring that the push rod 103 only moves transversely and linearly. The driving mechanism 102 may be an electric push rod.

Push rod 103 one end is articulated with connecting seat 201, specifically, in push rod 103 one end stretched into the recess 204 that connecting seat 201 was equipped with, installs the pivot in the recess 204, push rod 103 one end is equipped with the shaft hole, and the shaft hole is passed to the pivot for vertical deflection can take place for connecting seat 201. Step grooves communicated with the grooves 204 are symmetrically arranged on the connecting seat 201, a T-shaped sliding block 205 is slidably arranged in the step grooves, and a spring III 203 is connected between the T-shaped sliding block 205 and the groove bottom of the step grooves. When the connecting seat 201 deflects vertically, the push rod 103 can push the T-shaped slider 205 to press the third spring 203. Under the action of the elastic force of the third spring 203, the connecting seat 201 can be straightened as soon as possible.

An arc-shaped surface is arranged at one end of the T-shaped sliding block 205, which is contacted with the push rod 103, so that the connection seat 201 can deflect smoothly.

The connecting base 201 is fixedly connected with the locking rod 105, specifically, an insert cylinder 202 for inserting the locking rod 105 is fixedly connected to the connecting base 201, and the locking rod 105 is pinned with the insert cylinder 202. When the locking rod 105 deflects, it drives the connecting seat 201 to deflect together.

The locking rod 105 is inserted into a through hole 303 formed in the buffering guide seat 301, and a plurality of cushioning mechanisms are arranged on the wall of the through hole 303. Specifically, the buffering guide seat 301 is provided with a buffering groove 307 communicated with the through hole 303, the buffering mechanism comprises a sliding block 309 slidably mounted in the buffering groove 307, one end of the sliding block 309 extends into the through hole 303 and abuts against the locking rod 105, and a first spring 302 is connected between the other end of the sliding block 309 and the bottom of the buffering groove 307. A projection 308 is disposed on one side of the slider 309, and a stop block 306 is disposed on the other side of the slider 309. The buffer guide seat 301 is further provided with a side groove communicated with the buffer groove 307, a side sliding block 305 is transversely slidably arranged in the side groove, one end of the side sliding block 305 is connected with the bottom of the side groove through a second spring 304, and a pushing block 306 and the other end of the side sliding block 305 are provided with coupled inclined planes.

When the lock lever 105 deflects due to collision, the slider 309 is pressed against the first spring 302, and the side slider 305 moves due to the movement of the pressing block 306, so that the second spring 304 is compressed, thereby performing a buffering function. Under the elastic force of the first spring 302 and the second spring 304, the sliding block 305 returns, and after the sliding block 305 returns, the projection 308 abuts against the limiting groove wall of the buffer guide seat 301, so that the length of the sliding block 309 extending into the through hole 303 is fixed. Since all the sliders 309 extend the same length, the lock lever 105 is restored to the parallel state.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
