Novel mechanical jack

Abstract

The invention discloses a novel mechanical jack. The technical scheme adopted by the novel mechanical jack is that the novel mechanical jack comprises a supporting end head and a vertical column, thesupporting end head is installed at the top end of the vertical column, the vertical column penetrates through a push-out support plate and a supporting plate, the push-out support plate and the vertical column are provided with an included angle, the supporting plate is located below the push-out support plate, two ends of the supporting plate are provided with a first shaft pin and a second shaft pin which are capable of rotating correspondingly, four corners of the supporting plate are all provided with supporting legs, the first shaft pin is provided with a ripping rod, the second shaft pin is provided with a pulling plate, the pulling plate is sleeved on the vertical column, the ripping rod can rotate taking the first shaft pin as the axle, and the pulling plate can rotate taking thesecond shaft pin as the axle. The novel mechanical jack has the beneficial effects that the jack can be used in a small space and is convenient to carry.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment and relates to a novel mechanical jack. Background technique [0002] Jacks can be divided into three types according to their structural characteristics: rack jacks, screw jacks and hydraulic (oil pressure) jacks. According to other methods, it can be divided into separate jacks, horizontal jacks, claw jacks, synchronous jacks, hydraulic jacks, electric jacks, etc. Among them, the commonly used jacks include screw jacks, hydraulic jacks, and electric jacks. The hydraulic jack is based on the principle of Pascal's principle, that is, the pressure of the liquid is the same everywhere, so that in a balanced system, the pressure exerted on the smaller piston is relatively small, and the pressure exerted on the large piston is relatively small. Large, this keeps the liquid still. Therefore, through the transmission of liquid, different pressures on different ends can be obtained, so th...

AI Technical Summary

Problems solved by technology

The long-sized lever requires a relatively large working space. In most cases, when the lever is used, the lifting height of one end will be higher than the height of the plunger. In some narrow occasions, the lever cannot be well realized. original function

It also means that if the surrounding environment causes the use of the jack to be very small, this ordinary manpower hydraulic jack cannot realize the original function very well.
