Description

Hydraulic jack holding structure

Technical Field

The utility model relates to a jack uses technical field, and concrete field is a hydraulic jack structure of holding.

Background

The jack is light and small lifting equipment which takes a rigid jacking piece as a working device and jacks a heavy object through a top bracket or a bottom supporting claw within a small stroke. The jack is mainly used in the departments of factories, mines, transportation and the like as a vehicle repair, other lifting, supporting and other works, and the jack is divided into a mechanical jack, a hydraulic jack and the like, and the principles are different. In principle, the most basic principle on which a hydraulic drive is based is pascal's law, i.e. the pressure is uniform throughout the liquid. Thus, in a balanced system, a relatively small piston exerts a relatively small pressure on it, while a large piston exerts a relatively large pressure on it, which keeps the liquid still. Therefore, different pressures at different ends can be obtained by the liquid transfer, and the purpose of conversion can be achieved. The common hydraulic jack of people has just utilized this principle to reach the transmission of power, and current engineering construction jack, weight is bigger, and constructor removes very difficultly.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a hold hydraulic jack structure, including jack 1 and main frame 2, the rigid coupling of center department of main frame 2 has bull stick 7, sleeve 8 has been cup jointed to the outer wall of bull stick 7, sleeve 8's top rigid coupling has the one end of knee lever 9, the other end rigid coupling of knee lever 9 has top ring 10, sleeve 8's bottom rigid coupling has crank 4's one end, crank 4's other end outer wall has cup jointed plastic cover 5, two all have clamping ring 3 through 6 movable mounting of even axle around the bottom of main frame 2, the equal rigid coupling in one side that main frame 2 was kept away from to two clamping ring 3 has crank barrel 11, the inside rigid coupling of two crank barrel 11 has the both ends of rubber strip 12, the equal rigid coupling in one side that two clamping ring 3 are close to mutually has a section of thick bamboo 14, the inside of a section of thick bamboo 14 is pegged graft and has pivot 13, the inner wall rigid coupling of clamping ring.
