Abstract

The utility model relates to a lifting adjuster, belonging to the technical field of a hoisting tool. The utility model has the structure that a bottom seat and a cylinder are in hinging connection; the interior of the cylinder is connected and fixed with a screw nut through a bearing; the screw nut and a feed screw are in screw connection; one part which is extended outside the cylinder on the screw nut is provided with a handle. The utility model has the advantages of simple structure and flexible and convenient use and operation; the pressure force and the tensile force of a vertical line can be born, and the lateral pressure force and the tensile force can also be born.

Description

Lifting regulator

The utility model belongs to lifting facility technical field.

At present, the general lifting facility overwhelming majority is an oil jack, jack can only bear vertical line mono-pressure when work, can not bear pulling force, structure is comparatively complicated, and maintenance has certain inconvenience, and a kind of mechanical lifting facility are arranged in addition, though simple in structure, can not side direction bear pressure and pulling force.

What the purpose of this utility model provided a kind of physical construction both can bear vertical line pressure and pulling force, can bear the lifter of lateral pressure and pulling force again.

The technical solution of the utility model is as follows:

Be hinged between base and the cylinder body, be connected and fixed screw by upper and lower thrust baring in the cylinder body, screw and leading screw are by being threaded, and the leading screw bottom is fixed with back-up ring, at the screw that extends to outside the cylinder body handle are housed partly.

The utility model has the advantages that: this lifting regulator is simple in structure, manipulates flexible, convenience, in use both can bear pressure, can bear pulling force again, and can be automatically with changed by force direction when changed by force direction.Make this device more can bear maximum working load flexibly effectively.

Fig. 1 is a lifting regulator structure cutaway view.

This device is to utilize leading screw, screw transmission principle to carry out design-calculated, handle 9 drives screw 2 and rotates, leading screw 1 is finished entire work process do straight reciprocating motion, screw 2 is connected and fixed by up-thrust bearing 3 and lower thrust-bearing 4 with thick stick body 5, friction drag in the time of can reducing screw 2 and rotatablely move, the back-up ring 6 of leading screw 1 bottom can prevent that leading screw 1 from all screwing out from screw 2, it is near the center of circle forms certain angle vertical line swing that cylinder body 5 can cut with scissors 7, to bear from the pressure and the pulling force that are not the vertical line direction.

Claims

1, a kind of lifting regulator, it is characterized in that: be connected by hinge (7) between base (8) and the cylinder body (5), be connected and fixed screw (2) by upper and lower thrust baring (3), (4) in the cylinder body (5), screw (2) and leading screw (1) are by being threaded, leading screw (1) bottom is fixed with back-up ring (6), in screw (2) part that extends to cylinder body (5) outside handle (9) is housed.
