Storehouse and field multipurpose horizontal jack

Abstract

The invention discloses a storehouse and field multipurpose horizontal jack. The storehouse and field multipurpose horizontal jack comprises a jack body; the jack body comprises a bottom frame, an oil pump component, a lifting arm component, a tray component and a handle component; a front wheel component comprises two front rotating discs, a front wheel assembly, a front wheel limiting rod and a front positioning plug pin; a rear wheel component comprises two rear rotating discs, a rear wheel assembly, a rear wheel limiting rod and a rear positioning plug pin; each front rotating disc is divided into a front wheel frame and an upper gear shifting part, the upper gear shifting parts of the front rotating discs are pivoted to the outer sides of the front ends of the two wallboards, and a front low-gear positioning hole and a front low-gear positioning hole are formed in the upper part of each upper gear shifting part; each rear rotating disc is divided into a rear wheel frame and an upper rotating part; a front wheel assembly and a rear wheel assembly are installed at the bottom of the front wheel frame and the bottom of the rear wheel frame respectively; the upper rotating parts are pivoted on the outer sides of the rear ends of the two wallboards; a rear low gear positioning hole and a rear high gear positioning hole are formed in the upper part of each upper rotating part; and the front wheel limiting rod and the rear wheel limiting rod are supported on the bottom edges of the front and rear ends of the two wallboards at low and high gears. The invention has the beneficial effect that the ground clearance can be adjusted by multiple gears.

Description

technical field [0001] The invention relates to a warehouse and field multipurpose horizontal jack. Background technique [0002] Existing horizontal jack has the following problems: (1) it is usually required to be used on flat, hard ground. When using on sandy ground or soft ground, because the front and rear wheels are all relatively small and narrow, it is easy to sink into the ground and make the jack Invalidation; (2) also can't use in the place that has slope or uneven road surface; (3) the ground height of jack is less, so it is not suitable for vehicles with higher chassis such as off-road vehicles, and it is even more unsuitable for outdoor use. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a warehouse and field multi-purpose horizontal jack that can adjust the height from the ground in multiple levels and adapt to the changing outdoor conditions. [0004] A warehouse and field multi-purpose horizontal ja...
