Description

A kind of for auto repair factory high thrust jack
Technical field
This utility model relates to hydraulic test design field, particularly relates to a kind of for auto repair factory high thrust thousand Jin top.
Background technology
Jack is a kind of lifting simplest crane gear highly less than 1m, lifts part as work clothes with rigidity top Put, the light little crane gear of jacking weight in stroke by top bracket or bottom claw.Divide mechanical type and fluid pressure type two kinds, Jack is mainly used in the department such as factories and miness, transportation as Mechanical Help and other work such as lifting, support.Its light structure Firm, flexibility and reliability, a people i.e. portability and operation.Jack, as a kind of range instrument widely, have employed optimum The cast of matter, it is ensured that the quality of jack and service life.Jack is divided into mechanic jacks and hydraulic jack two Kind, principle is had nothing in common with each other.For from principle, hydraulic jack the principle on which is pascal's principle, it may be assumed that liquid is everywhere Pressure is consistent, and so, in the system of balance, the pressure that smaller piston upper applies is smaller, and big piston The pressure of upper applying is the biggest, so can keep the static of liquid.So by the transmission of liquid, different end can be obtained On different pressure, thus can reach one conversion purpose.We common to hydraulic jack utilize exactly This principle reaches the transmission of power.Mechanic jacks uses theory of mechanics, and back and forth to pull handle, pusher dog i.e. promotes ratchet Gap is turned round, and cone pinion drives large bevel gear, makes weight lifting screw rod rotate, and hoists so that jacking sleeve obtains or declines, and Reach the function of lifting pulling force, but be not as simple as hydraulic jack.Due in life our jack commonly used be all thrust relatively Little, it is impossible to meet the needs of integrated mill.
Utility model content
The purpose of this utility model is that provide a kind of pushes away greatly for auto repair factory to solve the problems referred to above Power jack.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of for auto repair factory high thrust jack, including bottom fixing sucking disk, base, large tank, body frame, institute Stating bottom fixing sucking disk and be provided above described base, described base is provided above oil return valve, and described oil return valve side is arranged Having ratchet group, described ratchet group to be provided above described large tank, described large tank side is provided with big piston, described big piston It is provided above described body frame, below described body frame, is provided with spacing hole, below described spacing hole, be provided with jacking sleeve, described It is provided with handle below jacking sleeve, below described handle, is provided with valve piston, below described valve piston, be provided with small oil tank, institute State small oil tank side and be provided with thrust bearing.
In said structure, move described valve piston by described handle down pressure zone and extrude described small oil tank, the most described little Oil inside oil cylinder will be extruded to inside described large tank, create thrust, described large tank inside the most described large tank By promoting described big piston upwards by internal expansion link, now by jack-up weight, once need blood pressure lowering when institute Stating ratchet group to unclamp, the oil inside described large tank will return to inside described small oil tank by described oil return valve, in order to prevent Deviating from described jacking sleeve when described big piston upwards, now spacing hole will carry out spacing in case causing danger.
In order to improve load bearing effect further, described bottom fixing sucking disk is connected with described base through screws, described time Fuel tap is connected by oil pipe with described large tank.
In order to improve load bearing effect further, described big piston is with described large tank by the expansion link of described large tank even Connecing, described body frame is connected with described base through screws.
In order to improve load bearing effect further, described spacing hole is embedded in the inside of described jacking sleeve, described lifting set Cylinder is embedded in the inside of described body frame.
In order to improve load bearing effect further, described handle is connected with described valve piston, described valve piston and described thrust Bearing connects.
Having the beneficial effects that: greatly improve load bearing effect, not only stability is high, and simple to operate, is easily carried.
Accompanying drawing explanation
Fig. 1 is a kind of front view for auto repair factory high thrust jack described in the utility model.
1, bottom fixing sucking disk;2, chassis;3, oil return valve;4, ratchet group;5, large tank;6, big piston;7, body frame;8, limit Hole, position;9, jacking sleeve;10, handle;11, valve piston;12, small oil tank;13, thrust bearing.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, a kind of for auto repair factory high thrust jack, including bottom fixing sucking disk 1, base 2, big Oil cylinder 5, body frame 7, bottom fixing sucking disk 1 is provided above base 2, and base 2 plays effect that is stable and that support, above base 2 Be provided with oil return valve 3, oil return valve 3 after blood pressure lowering oil flow through valve, oil return valve 3 side is provided with ratchet group 4, ratchet group 4 For switching increase and decrease pressure, ratchet group 4 is provided above large tank 5, and large tank 5 side is provided with big piston 6, and big piston 6 is used for Promoting weight, big piston 6 is provided above body frame 7, and this device is played fixing effect by body frame 7, arranges limited below body frame 7 Hole 8, position, spacing hole 8 prevents big piston 6 from deviating from, is provided with jacking sleeve 9, is provided with hands below jacking sleeve 9 below spacing hole 8 Handle 10, handle 10 is used for pressurizeing, and is provided with valve piston 11 below handle 10, and valve piston 11 is used for promoting small oil tank 12, valve piston Being provided with small oil tank 12 below 11, small oil tank 12 is for being expressed to oil inside large tank 5, and small oil tank 12 side is provided with thrust Bearing 13.
In said structure, move valve piston 11 by handle 10 down pressure zone and extrude small oil tank 12, then inside small oil tank 12 Oil will be extruded to inside large tank 5, now create thrust inside large tank 5, large tank 5 will be by internal expansion link Promoting big piston 6 to move upward, now by jack-up weight, the when of once needing blood pressure lowering, ratchet group 4 is unclamped, inside large tank 5 Oil will return to inside small oil tank 12 by oil return valve 3, time in order to prevent big piston 6 from moving upward deviate from jacking sleeve 9, Now spacing hole 8 will carry out spacing in case causing danger.
In order to improve load bearing effect further, bottom fixing sucking disk 1 is connected by screw with base 2, oil return valve 3 and big oil Cylinder 5 is connected by oil pipe, and big piston 6 is connected by the expansion link of large tank 5 with large tank 5, and body frame 7 and base 2 pass through screw Connecting, spacing hole 8 is embedded in the inside of jacking sleeve 9, and jacking sleeve 9 is embedded in the inside of body frame 7, handle 10 and valve piston 11 Connecting, valve piston 11 is connected with thrust bearing 13.
