Embodiment Construction

[0023] As shown in the figure, a screw 8 is fixed on the bearing seat 11 through a bearing, and a driving bevel gear 10 is arranged in the middle of the screw 8, and the passive bevel gear 9 meshes with the driving bevel gear 10 on the output shaft of the power source, and the screw Threaded slide block 7 is respectively installed on both sides of upper bevel gear, and nut slide block 7 is connected and fixed on the top of two scissors with bearing pin 12, and the slide block of scissors 4 lower ends is placed in the sliding groove of base 5.

[0024] In this way, the operator is supported on the platform and shakes the crank handle with his hands in the direction, and the rotation of the bevel gear causes the nut slider 7 installed at both ends of the screw 8 to move to the middle at the same time, and the shears fixed on the nut slider 7 through the pin shaft 12 The fork 4 gradually closes with the movement of the nut slider, so that the platform 3 rises steadily, lifts the o...

Abstract

The invention discloses a manual twin screw lifting platform which is widely applied to occasions, such as a library, a supermarket, building installation, indoor and outdoor decoration, electrical installation and maintenance and the like. In the manual twin screw lifting platform, a bearing seat is fixed with a screw through a bearing; the middle of the screw is provided with a driven conical gear which is meshed with a driving conical gear on a power source output shaft; two sides of the driven conical gear on the screw are provided with a nut sliding block respectively; the nut sliding blocks are connected through an axis pin and are fixed on the tops of two scissors; and the lower ends of the scissor are arranged in a sliding groove of a foundation. One person can stand on the platform and shake the rocking handle of the platform so as to be lifted. The lifting platform is not needed to be driven by electricity, the self weight of the lifting platform is reduced, labor is saved during carrying operation, the platform is lifted in a balanced way, is easy to position and can be operated and used safely and conveniently on various occasions.

Description

technical field [0001] The invention relates to a lifting platform, in particular to a manual lifting platform suitable for vertical lifting operations in libraries, supermarkets, indoor and outdoor electrical decoration, building installation, etc. Background technique [0002] The scissor platform is a commonly used convenient vertical aerial work climbing tool.
