Lifting device capable of positioning corner

Abstract

A lifting device capable of positioning corners, one end of the handle is fixedly connected to one end of the push rod on the base plate, the other end of the push rod is opened with a U-shaped groove, and the push rod and one end of the guide rod are hinged in the U-shaped groove There is a hinge seat on the bottom plate, and the guide rod passes through the bottom plate and is hinged on the hinge seat at the same time; the middle part of the push rod is fixed with a tension spring, and the other end of the tension spring passes through the bottom plate, and is connected with the fixed guide groove under the bottom plate. The ends are connected; the end of the guide groove is also connected with a compression spring, and the other end of the compression spring is connected with the guide rod passing through the guide groove; the outer cylinder is provided with a chuck and a chuck sleeve, and the chuck and the chuck sleeve interfere Cooperate, the chuck sleeve engages with the base cylinder, and both the chuck sleeve and the base cylinder are tightly clamped on the outer cylinder; the lower part of the base cylinder is fixed on the base; Compatible card slot. The lifting mechanism can realize the function of rotating and positioning while ensuring the lifting function, improves the performance of the lifting mechanism, has a simple structure, and is flexible and convenient to operate.

Description

technical field [0001] The invention relates to a lifting mechanism, in particular to a lifting device capable of positioning a corner. Background technique [0002] Existing rotatable lifting mechanism usually adopts pneumatic lifting device. For example, the patent No. 02250660.8 is the reinforced pneumatic lifting rod. When the lifting device needs to be rotated at a certain angle, it cannot be automatically positioned at the required rotating position, but requires the user to use additional force or devices to clamp and fix it. , very inconvenient to use. Contents of the invention [0003] The object of the present invention is to provide a lifting device capable of locating corners. The lifting mechanism can realize the function of rotating and positioning while ensuring the lifting function, and improve the performance of the lifting mechanism. It has a simple structure and is flexible and convenient to operate. [0004] The present invention solves its technical ...
