Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.

As shown in fig. 1 to 4, the vertical self-lifting locking platform comprises a platform 1, guide pillars 2 are vertically arranged at four corners of the platform 1, a C-shaped frame 3 is arranged in the middle of the platform 1, the C-shaped frame 3 comprises two side plates and a bottom plate located between the side plates, a vertical strip-shaped hole 4 is formed in the bottom plate, a first rack 5 is arranged on the rear side of the inner end face of the side plate on the left side, a second rack 6 is arranged on the front side of the inner end face of the side plate on the right side, a first gear 7 is arranged on the rear side inside the C-shaped frame 3, a second gear 8 is arranged on the front side inside the C-shaped frame 3, the first gear 7 is engaged with the first rack 5, and the right side of the first gear 7 abuts against the inner wall on the right side of the C-shaped frame 3, so that the first gear 7 is prevented from being disengaged from the first rack 5; the second gear 8 is meshed with the second rack 6, and a gap is reserved between the left side of the second gear 8 and the inner wall of the left side of the C-shaped frame 3; a longitudinal first shaft 9 is arranged in the center of the first gear 7, the section of the first shaft 9 is rectangular, a support plate 10 is movably sleeved at the rear end of the first shaft 9 through the strip-shaped hole 4, the support plate 10 is positioned behind the C-shaped frame 3, the lower end of the support plate 10 is fixed on the platform 1, the front end of the first shaft 9 penetrates through the second gear 8 and turns 90 degrees to the right, a rectangular hole 11 is formed in the middle of the second gear 8, the width of the rectangular hole 11 is twice of the width of the first shaft 9, and when the second gear 8 is meshed with the second rack 6, the first shaft 9 is positioned at the leftmost side of the rectangular hole 11; and a second shaft 12 fixed on the right side of the rectangular hole 11 is longitudinally arranged on the front end surface of the second gear 8, the front end of the second shaft 12 also turns 90 degrees to the right, and the front end surface of the second shaft 12 is attached to the rear end surface of the first shaft 9.

The gap between the left side of the second gear 8 and the inner wall of the left side of the C-shaped frame 3 is larger than the width of the first shaft 9.

The right end of the first shaft 9 is connected with a movable handle 13 in a hinged mode and hinged to the middle of the movable handle 13, a waist-shaped hole 14 is formed in the rear portion of the movable handle 13, and the right end of the second shaft 12 is hinged to the inside of the waist-shaped hole 14.
