Abstract

A locking mechanism comprises a main body, an ejector rod, a guide rod assembly, a carrier plate and a fixing assembly. The carrier plate comprises a center hole and a plurality of annular strip holes. The fixing assembly comprises a rotary disc. The center hole and the annular strip holes can lock the rotary disc in different rotation angles. The guide rod assembly limits the rotation tolerance of the carrier plate, and makes the carrier plate move up and down in the vertical direction. The rotary disc with limited rotational freedom is fixedly connected with the ejector rod, so that the locking mechanism can not only realize the linear lifting motion of the ejector rod, but also reduce the rotation angle error between the carrier plate and the ejector rod. A rotating lifting platform is also provided.

First claim

What is claimed is:

1 . A rotating lifting platform, comprising:
a main body; an ejector rod movably connected to the main body; a guide rod assembly fixedly connected to the main body; a carrier plate fixedly connected to the guide rod assembly, wherein the carrier plate comprises a center hole and a plurality of annular strip holes, the plurality of annular strip holes are distributed on a circumference with the center hole as a first center of a first circle; and a fixing assembly comprising a first connecting piece, a second connecting piece, and a rotary disc, wherein the rotary disc comprises a fixing hole and a positioning hole, the fixing hole is interconnected with the center hole and is fixed with the center hole through the first connecting piece, the annular strip hole is interconnected with the positioning hole and is fixed with the positioning hole through the second connecting piece, the fixing assembly is fixedly connected to the ejector rod, the fixing assembly is configured to reduce a rotation error caused by the ejector rod.

2 . The rotating lifting platform of claim 1 , wherein the second connecting piece is a bolt, the bolt is fixedly connected with a surface of the positioning hole, and the bolt rests on a surface of the annular strip hole.

3 . The rotating lifting platform of claim 1 , wherein multiple positioning holes are uniformly distributed on the circumference with the fixing hole as the first center of the first circle.

4 . The rotating lifting platform of claim 3 , wherein an arc length of a first arc formed by two adjacent positioning holes is A, and a second arc length of the annular strip hole is B, which satisfies a condition of B=n*A, n is a positive integer.

5 . The rotating lifting platform of claim 1 , wherein the carrier plate comprises at least two annular strip holes, and the at least two annular strip holes are uniformly distributed on the carrier plate with the center hole as the first center of the first circle.

6 . The rotating lifting platform of claim 5 , wherein at least two second connecting pieces are set in the at least two annular strip holes and the positioning hole, and the second connecting pieces are set evenly with the first connecting pieces as a second center of a second circle.

7 . The rotating lifting platform 1 , wherein the guide rod assembly comprises a telescopic rod, the telescopic rod is arranged on both sides of the main body, the telescopic rod is retractably connected with the carrier plate, the ejector rod is arranged in the middle of the main body and is fixedly connected to a surface of the fixing hole, the ejector rod is configured to lift the carrier plate.

8 . The rotating lifting platform of claim 7 , wherein the ejector rod comprises a clamping club and a stabilizing plate, the clamping club is movably set in a middle of the stabilizing plate, and one end of the fixing assembly away from the carrier plate comprises a clamping slot, the clamping slot and the fixing hole are arranged in a coaxial, the clamping club and a surface of the clamping slot are mutually compatible and fixedly connected.

9 . The rotating lifting platform of claim 7 , wherein the guide rod assembly further comprises a guide sleeve, the guide sleeve is connected to the telescopic rod and outside the telescopic rod, and the guide sleeve is further fixedly connected with the main body.

10 . The rotating lifting platform of claim 9 , wherein the guide sleeve comprises a straight hollow cavity, and the telescopic rod is movably set in the straight hollow cavity.
