Description

Portable jack

Technical Field

The utility model relates to a jack technical field, concretely relates to portable jack.

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 the work of vehicle repair, other lifting, supporting and the like, and can be divided into three types, namely a rack jack, a screw jack and a hydraulic (oil pressure) jack according to the structural characteristics. And can be divided into a separation type jack, a horizontal type jack, a claw type jack, a synchronous jack, an oil pressure jack, an electric jack and the like according to other modes. The common jacks include screw jacks, hydraulic jacks, electric jacks and the like. The principle on which hydraulic jacks are based is the pascal principle, namely: the pressure is uniform throughout the liquid so that in a balanced system, a smaller piston exerts a smaller pressure on top of a larger piston, which can keep the liquid still. Different pressures at different ends can be obtained by the transfer of liquid, so that a change can be achieved. The common hydraulic jack uses the principle to achieve the force transmission. The mechanical jack adopts a mechanical principle, a handle is pulled repeatedly, a claw is arranged to move a ratchet wheel to rotate in a clearance mode, a bevel pinion drives a bevel pinion to rotate a lifting screw rod, and therefore a lifting sleeve is lifted or lowered to achieve the function of lifting tension, but the mechanical jack is not as simple as a hydraulic jack. But the existing jack is inconvenient to store and carry. The patent document of application number CN201820441776.0 discloses a jack convenient to carry, which comprises a supporting end (1) and an upright post (2), wherein the upright post (2) is a hollow tube, the supporting end (1) is installed at the top end of the upright post (2), the upright post (2) penetrates through an ejection support plate (3) and a support plate (4), the support plate (4) is positioned below the ejection support plate (3), a first shaft pin (5) and a second shaft pin (6) which can rotate are respectively installed at two ends of the support plate (4), supporting legs (7) are respectively arranged at four corners of the support plate (4), a prying bar (8) is installed on the first shaft pin (5), a pulling plate (9) is installed on the second shaft pin (6), the pulling plate (9) is sleeved on the upright post (2), the prying bar (8) can rotate by taking the first shaft pin (5) as an axis, the pulling plate (9) can rotate by taking the second shaft pin (6) as an axis, and the structure is adopted, so that the jack can be used in a small space, but it is still inconvenient to carry and easily causes the collision to the jack in the process of carrying, causes the damage to the jack.
