Problems solved by technology

These jacks have a large total volume, heavy lifting weight, and are not easy to carry. They are not suitable for lifting and handling lighter objects in the logistics and storage industries.
Moreover, when hydraulic or mechanical jacks are used in the pressing process of food processing, due to problems such as mechanical clearance and hydraulic sealing, it is easy to cause problems such as extrusion rebound.

Embodiment 1

[0021] A flexible jack based on pneumatic technology includes a jacking cylinder, a pedal cylinder, a pedal and a connecting pipeline; step on the pedal, the pedal cylinder will fill the jacking cylinder with air, and drive the jacking cylinder to rise; release the pedal, the pedal will The cylinder resets and inhales air; the jacking cylinder exhausts to realize the lowering of heavy objects or the reset of the jacking cylinder.

[0022] The foot cylinder is a spring-return, extended-type single-acting cylinder with one inlet and one outlet. The jacking cylinder is a spring return retractable single-acting cylinder, equipped with one intake channel and two exhaust channels, the two exhaust channels are slow exhaust channel and fast exhaust channel respectively. The intake channel of the pedal cylinder is equipped with a filter and a one-way valve of the pedal cylinder successively according to the air flow direction. The air intake channel of the jacking cylinder is equipped...

Abstract

The invention relates to a flexible jack based on the pneumatic technology, and belongs to the technical field of mechanical engineering. The flexible jack based on the pneumatic technology comprises a jacking cylinder, a foot cylinder, a pedal and a connecting pipeline. By treading the pedal, the foot cylinder can fill air into the jacking cylinder to drive the jacking cylinder to ascend. By loosening the pedal, the pedal cylinder is reset and sucks air. The jacking cylinder exhausts the air, so that a heavy object is laid down or the jacking cylinder is reset. The flexible jack based on the pneumatic technology has the advantages of being scientific in design, convenient to use, stable to work, lasting and capable of achieving pressure maintaining, portable to carry, environmentally friendly, capable of being widely applied to the fields of heavy object jacking and squeezing, and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, in particular to a flexible jack based on pneumatic technology. Background technique [0002] In the logistics, storage, and pressing industries, jacks are widely used. At present, jacks are mainly hydraulic and mechanical. These jacks themselves have a large total amount, a large lifting weight, and are not easy to carry, so they are not suitable for lifting and carrying lighter objects in logistics and storage industries. Moreover, when hydraulic or mechanical jacks are used in the pressing process of food processing, due to problems such as mechanical clearance and hydraulic sealing, it is easy to cause problems such as extrusion rebound. Contents of the invention [0003] The invention provides a flexible jack based on pneumatic technology to solve the technical problems in the known technology. [0004] The object of the present invention is to provide a jack with scienti...
