Description

A kind of lightweight single leg support recreational vehicle electric jack stand
Technical field
The present invention relates to a kind of jack stand, more particularly to a kind of very heavy topmast of lightweight single leg support recreational vehicle electric Frame.
Background technology
Jack refers to using rigid top lift part as equipment, by the small stroke of top bracket or bottom claw The light and small lifting equipment of open-top weight, jack are mainly used for the departments such as factories and miness, communications and transportation as Mechanical Help and other The work such as weight, support, light structure is firm, flexibility and reliability, and a people can carry and operate, and jack, which is divided into, mechanical jack Top and hydraulic jack etc., principle is had nothing in common with each other.For from principle, the most basic principle that hydraulic drive is based on is exactly pa Si Kadinglv, that is to say, that the pressure of liquid everywhere is consistent, and in the system of balance, smaller piston upper applies Pressure it is smaller, and the pressure applied on big piston is also bigger, can keep the static of liquid in this way, so passing through liquid The transmission of body can obtain pressure different on different ends, so that it may with achieve the purpose that one transformation, people the common liquid arrived Pressure jack is exactly that this principle is utilized to reach the transmission of power, and back and forth to pull handle, pusher dog pushes on jin top under spiral Ratchet gap turn round, cone pinion drive large bevel gear, make weight lifting screw rod rotate, to make jacking sleeve obtain raising or under Drop, and reach the function of lifting pulling force.
On the basis of the technical conditions of existing jack stand, in the range used and convenience of jack Still remain many deficiencies, most of jack all uses single-point type to support, more single using structure, contact bearing area compared with Small, there are some potential safety problemss when use, it has not been convenient to use be adjusted, causing jack to use, there are certain limitations Property.
Invention content
The technical problem to be solved by the present invention is to overcome the defects of the prior art, provide a kind of lightweight single leg support caravan The support base of motor-driven jack holder, the jack stand is changed to 2 points of supports by single-point support, increases forced area, can root According to needing to be changed, is assembled by the adjustment hole of setting, adjust and support base length, practicality easy to operate can be changed.
In order to solve the above technical problem, the present invention provides the following technical solutions:
A kind of lightweight single leg support recreational vehicle electric jack stand of the present invention, including jack body frame, the jack body frame Bottom end be provided with firm banking, the inside both ends of the firm banking are both provided with pedestal positioning pin, the firm banking Both sides are both provided with body frame connecting pin, and support base, the top end surface of the support base are equipped at the top of the jack body frame It is provided with anti-skid rubber cushion, flexible connection pin is provided on the inside of the support base, one end of the support base is provided with sliding Slot is provided with adjustment hole on the top of the jack body frame, and flexible connection pin is provided on the adjustment hole.
As a preferred technical solution of the present invention, the both ends of the jack body frame are mounted on screw connecting piece, Through having threaded rod, one end of the threaded rod to be connected with motor driving, the motor drives for the inside of the screw connecting piece Bottom end be provided with control cabinet.
As a preferred technical solution of the present invention, the flexible connection pin is slidably connected with sliding groove.
As a preferred technical solution of the present invention, the firm banking passes through body frame connecting pin phase with jack body frame Connection.
Compared with prior art, beneficial effects of the present invention are as follows:
The present invention is a kind of lightweight single leg support recreational vehicle electric jack stand, can effectively be improved making for jack stand 2 points of supports are changed to by single-point support with the support base of range and convenience, the jack stand, increase forced area, it can It is changed, is assembled by the adjustment hole of setting as needed, adjust and support base length, practicality easy to operate can be changed.
