Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical jacks, and particularly relates to a mechanical jack with a small displacement function. Background Technique

[0002] A screw jack, also known as a mechanical jack, is driven by human power through a screw pair. The screw or nut sleeve serves as the lifting member. An ordinary screw jack supports heavy objects by the self-locking function of the thread. It has a simple structure, but low transmission efficiency and slow return. The self-lowering screw jack has no self-locking function on the thread and is equipped with a brake. When the brake is released, the heavy object can quickly descend by itself, shortening the return time. However, this kind of jack has a more complex structure. The screw jack can support heavy objects for a long time, and the maximum lifting weight has reached 100 tons, with wide application. After installing a horizontal screw at the lower part, it can also make the heavy object move horizontally for a short distance.

[0003] When a conventional mechanical jack supports a pipe body, in order to facilitate the processing of the pipe body, multiple jacks are usually used in cooperation. And after the jack supports the pipe body, it is unable to effectively adjust the position of the pipe body, thus affecting the practicability of the jack. For this reason, we propose a mechanical jack with a small displacement function. Content of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a mechanical jack with a small displacement function, effectively solving the problems raised in the background technique.
