Description

Anti-scraping saddle type rubber top horizontal jack

Technical Field

The utility model relates to a jack especially relates to a prevent scraping horizontal jack of saddle rubber top.

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 for the departments of factories, mines, transportation and the like as vehicle repair, other lifting, supporting and the like. The structure is light, firm, flexible and reliable, the lifting jack can be carried and operated by one person, the lifting jack is divided into a mechanical lifting jack, a hydraulic lifting 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 uses the principle to achieve the force transmission. The screw jack pulls the handle in a reciprocating way, the claw pushes the ratchet wheel to rotate in a clearance way, the bevel pinion drives the bevel pinion to rotate the lifting screw rod, and therefore the lifting sleeve can be lifted or descended to achieve the function of lifting tension, but the screw jack is not as simple as a hydraulic jack.

Patent numbers: CN106241642A discloses a horizontal jack, which includes a jack base, a hole extending in the front-rear direction is provided on the jack base to form an oil cavity of an oil tank, a valve cavity is provided between a piston mechanism and the oil tank on the jack base, a check valve core and an unloading valve core are provided in the valve cavity, so that the oil tank, the check valve and the unloading valve are all integrated on the jack base, and the horizontal jack has compact structure and reduced volume.
