Problems solved by technology

Ordinary screw jacks support heavy objects by thread self-locking effect. The structure is simple, but the transmission efficiency is low. When lifting objects at a high position, the lifting speed of the jacking mechanism is slow, and the return journey is slow.

Abstract

The invention relates to a thread jack with the rapid jacking function. The thread jack comprises a supporting ring, a jacking mechanism and a base sleeve which are connected in sequence. The base sleeve is composed of a hollow cylinder at the upper end and a hollow circular truncated cone at the lower end. A pair of small holes are correspondingly formed in the two sides of the hollow cylinder. The jacking mechanism comprises a jacking rod, a fixed insertion rod, a threaded rod and a handle. The jacking rod is arranged in the base sleeve and the top end of the jacking rod is provided with a threaded hole with which the threaded rod is connected. Multiple through holes A are axially and evenly distributed in the jacking rod. A circular channel in which the fixed insertion rod is inserted is formed by the through holes A and the small holes in the base sleeve. The fixed insertion rod is arranged in the circular channel. The threaded rod is connected to the top end of the jacking rod and a through hole B in which the handle is inserted is formed in the threaded rod in the radial direction. The thread jack has the beneficial effects that the jacking rod is arranged, an object can be located in the jacking range rapidly, and the thread jack can be suitable for jacking the high object.

Description

technical field [0001] The invention relates to a lifting device, in particular to a jack. Background technique [0002] The screw jack is driven by manpower through the screw pair, and the screw rod or nut sleeve is used as a small lifting device for lifting parts. Ordinary screw jacks support heavy objects by the thread self-locking effect, and the structure is simple, but the transmission efficiency is low. When lifting objects at a higher position, the lifting mechanism is slow in rising speed and slow in return. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fast jacking screw jack [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a fast-lifting threaded jack, the innovation point of which is that it includes a supporting cup, a jacking mechanism and a base sleeve connected in sequence; the base sleeve is composed of an upper end It co...
