Abstract

The utility model relates to a portable jack which is a jack device for lifting a load. An inflation type lifting structure is composed of a high pressure air bag and an air guiding pipe which are connected. The utility model which can be used for vertically lifting objects and automatically moving the objects and can support a whole vehicle has a supporting type structure. The utility model has the advantages of small size, light weight, portability, small space position for installation, time saving, trouble saving, labour saving, flexible, portable, and fast use, safe operation, convenient repair, no other accidents, and good safe performance. In addition, the objects are stable after lifted.

Description

Jiggle jack

The utility model relates to a kind of jack device of lifting load.

The jack device that is used for lifting load at present, common have a mechanical type, fluid pressure type and electrodynamic type, the deficiencies in the prior art part mainly is: 1, the volume of these devices is big, heavy, carries inconvenience.2, usability is poor, the installing space position that need can enter than ambassador's jack, otherwise put to enter; They all lean on the manual action lifting, normal have that firmly scope is little, even can't exert all one's effort, and are very difficult in the use, are subjected to the restriction of all multifactor, conditions.As, in the running car, the accident that occurs blowing out and so on, vehicle bridge are during near ground, and Chang Wufa is encased inside jack under the car; Even filled in also very time-consuming bothersome.3, be a support type structure, the area of contact between object and jack is little, and other contingency appears in object shakiness easily after the lifting.

The purpose of this utility model is to avoid weak point of the prior art, and provides a kind of volume little, the hand-held design jack product of the good and stable working of usability.

Can take following technical scheme to realize purpose.It is made the inflatable lifting structure that is connected and composed by high pressure airbag and ventilation flue.If ventilation flue's inlet end can join with automobile exhaust pipe, then can be made into a kind of inflatable jack product that utilizes the exhaust of automobile as power.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Accompanying drawing is a kind of structural representation of automobile type jiggle jack.

Jiggle jack mesohigh airbag (1), ventilation flue's (2) specific constructive form, be one-piece construction, or split combination structure, the shape of high pressure airbag, size, ventilation flue's length, thickness etc. all can be selected according to using needs to take the circumstances into consideration, as long as high pressure airbag, ventilation flue can bear corresponding pressure, the hard thing of unlikely everywhere quilt punctures, and can satisfy the in-use performance requirement.To be shrunk to the high pressure airbag of sheet during use, fill in the appropriate location of automobile to be hoisted or other underbody; Connect the ventilation flue, ventilation flue's inlet end is connected mutually with the freeing pipe of source of the gas or automobile self or other automobile; Start source of the gas or automobile, throttle a little, just can hold up automobile or other object very soon, realize lifting.

In the jiggle jack example shown in the drawings, high pressure airbag (1) is that the upper and lower part is structure thicker H, and the air-tightness member of one-way cock (3) is equipped with at the admission port place.It can adopt nylon fiber, canvas kiss-coating and so on multilayer, powerful flexible material manufacturing.One-way cock can select for use air-tightness one-way cock that existing various air pumps are used or other is fit to constitute.

More convenient and flexible in order to use, shown automobile type jiggle jack, its ventilation flue (2) is the high pressure hose that is connected and composed by basic pipe A and extension pipe B; The front end of basic pipe is the horn-like structure that can be connected with automobile exhaust pipe and one-way cock (3) is housed; All be connected between ventilation flue and high pressure airbag and between ventilation flue's basic pipe and extension pipe with demountable structure.As, in high pressure airbag admission port place dress swivel joint, one-way cock is arranged in the joint, and equipped Airtight gasket; Demountable structure can be a screw element, also can adopt fire-fighting high-pressure water pipe joint type structure or other member to constitute.The ventilation flue can adopt plastic hose, nylon hose and other various suitable flexible pipes of existing various energy bearing certain pressure to make.During automobile self air feed, only get final product, during by other automobile air feed, with extension pipe and the coupling of basic pipe with basic pipe.The inflatable jack is made maximum and is born two tons of pressure and be advisable in, is specially adapted to various small passenger cars, minicar etc.

The relative prior art of the technical program has following advantage and effect:

1, the volume of this jack is little, and is in light weight, easy to carry.

2, usability is good, only needs very little installing space position; Need not manual action, save time save trouble, laborsaving; Use flexibly, light, quick, substantially be not subjected to environment, condition restriction, the scope of application is wide; Function is varied, but both vertical lifting, also can utilize the arranged in dislocation of high pressure airbag top and the bottom, realize that the object center of gravity shifts, i.e. automated movement object, this function is specially adapted to automobile and is in the dangerous situation situation and uses, fallen into outside the bridge, when the chassis lands such as vehicle wheel section, can progressively vehicle be moved to home, need not crane and so on large-scale plant, it is very safe and reliable to work.

3, be face support type structure, the area of contact between object and jack is very big, and object is steady after the lifting, can be with the whole picking-up of vehicle, and convenient the repairing other contingency can not occur, and safety is good.

Claims

1, a kind of jiggle jack is characterized in that: it is the inflatable lifting structure that is connected and composed by high pressure airbag (1) and ventilation flue (2).

2, jiggle jack as claimed in claim 1 is characterized in that: high pressure airbag (1) is that the upper and lower part is structure thicker H, and the air-tightness member of one-way cock (3) is equipped with at the admission port place.

3, as claim 1,2 described jiggle jacks, it is characterized in that: its ventilation flue (2) is the high pressure hose that is connected and composed by basic pipe A and extension pipe B; The front end of basic pipe is the horn-like structure that can be connected with automobile exhaust pipe and one-way cock (3) is housed: all be connected with demountable structure between the basic pipe that reaches the ventilation flue between ventilation flue and high pressure airbag and extension pipe.
