Description
Jack fixing structure Technical Field The utility model relates to a jack fixing structure. Background The jack can be divided into a mechanical jack and a hydraulic jack according to the working principle, and a screw jack, a hydraulic jack and an electric hydraulic jack are commonly used for lifting. The hydraulic jack is based on the most basic pascal law in principle, and the pressure of the liquid is uniform all over. In a balanced system, the pressure exerted on a smaller piston is smaller, while a larger piston exerts a larger pressure ratio, which can keep the liquid stationary. So that different pressures at different ends can be obtained through liquid transmission, the aim of changing can be achieved, and the hydraulic electric jack commonly seen by people utilizes the principle to achieve force transmission. The screw jack is a screw jack which pulls the handle in a reciprocating manner, the pulling claw pushes the ratchet wheel to rotate in a clearance manner, the small bevel gear drives the large bevel gear to enable the lifting screw to rotate, and therefore the lifting sleeve is lifted or lowered, and the lifting tension function is achieved. However, most of the existing jacks are directly placed on flat ground when in use, and are designed aiming at the bottom surface with certain hardness, and usually do not consider soft ground lifting working conditions, inclined angle straight lifting working conditions and the like, so that the use limitation exists. Disclosure of utility model The utility model aims at improving the problems existing in the prior art, namely the technical problem to be solved by the utility model is to provide a jack fixing structure which is reasonable in design and improves the use flexibility. In order to achieve the purpose, the jack fixing structure comprises a jack body and a fixer arranged below the jack body, wherein the fixer comprises a fixing inserted rod which is vertically arranged and used for being inserted into the ground, the top of the fixing inserted rod is detachably connected with the bottom of the jack body, and a stress plate which is used for being in contact with the ground is hinged to the fixing inserted rod. Further, the middle part of atress board has been seted up in order to do benefit to fixed inserted bar along vertical rectangular groove that runs through, fixed inserted bar is articulated mutually with the lateral wall in rectangular groove through articulated round pin axle. Further, the lower end of the fixed inserted link is sharp. Further, the upper end of the jack body is hinged with a reinforcing bolt. Further, the jack body includes jack support, footstock, worm gear pair, motor assembly, the footstock sets up in jack support top, worm gear pair sets up inside the jack support, and worm gear pair's power input is connected with motor assembly, and worm gear pair's power take off is connected with the footstock through the driving medium, and motor assembly passes through worm gear pair, driving medium drive footstock and goes up and down. The jack is characterized in that the transmission piece comprises a jacking sleeve and a vertical screw shaft, the vertical screw shaft is rotatably arranged inside the jack support, the vertical screw shaft is connected with the worm gear pair and driven to rotate by the worm gear pair, the top seat is arranged at the upper end of the jacking sleeve, the jacking sleeve is sleeved outside the vertical screw shaft and is in threaded connection with the vertical screw shaft, the jacking sleeve is in vertical sliding fit with the jack support, and the jacking sleeve and the top seat are driven to lift when the vertical screw shaft rotates.
