Abstract
The utility model provides a kind of Pneumatic jack, comprise load-carrying cylinder and the cylinder of exerting pressure, wherein, load-carrying cylinder and the cylinder of exerting pressure are cylindrical shape, bottom conducting, form U-shaped pipe, in two cylinder bodies, all there is piston, execute pressure cylinder piston central authorities and be provided with one way switch, control the air inlet cylinder that prevents from exerting pressure and give vent to anger outside cylinder body, on the piston by the load-carrying cylinder at Pneumatic jack, non-return switch is set, the unexpected decline of piston when preventing from leaking gas, when can well accomplishing the protection of gas leakage and leaking gas, prevent that piston from declining and cause the damage of jack or jeopardize personal safety suddenly.
Description
Technical field
The utility model relates to jack field, relates in particular to a kind of Pneumatic jack.
Background technology
In prior art, jack is widely used in every field, and jack as its name suggests, be in will supporting, to measure very large object, in the time leaking gas in air cylinder, piston can decline suddenly, not only can cause the damage of jack, also may cause unnecessary accident simultaneously, endanger personal safety.
Therefore, prior art has yet to be improved and developed.
Summary of the invention
The technical problems to be solved in the utility model is the wheel leakage protective of jack, for the above-mentioned defect of prior art, provides a kind of Pneumatic jack.
The technical scheme that the utility model technical solution problem adopts is as follows: a kind of Pneumatic jack, comprise load-carrying cylinder and the cylinder of exerting pressure, wherein, load-carrying cylinder and the cylinder of exerting pressure are cylindrical shape, bottom conducting, forms U-shaped pipe, in two cylinder bodies, all has piston, execute pressure cylinder piston central authorities and be provided with one way switch, control the air inlet cylinder that prevents from exerting pressure and give vent to anger outside cylinder body.
Described Pneumatic jack, wherein, is provided with non-return switch on the piston of described load-carrying cylinder, for support piston, prevents that piston from falling.
Described Pneumatic jack, wherein, the piston radius of described load-carrying cylinder is 10 times of piston radius of cylinder of exerting pressure.
Beneficial effect: on the piston of the utility model by the load-carrying cylinder at Pneumatic jack, non-return switch is set, the unexpected decline of piston while being used for preventing from leaking gas, be provided with one-way air inlet switch at the cylinder of exerting pressure, gas can only enter the cylinder of exerting pressure, can not leak to atmosphere from the cylinder of exerting pressure, when the utility model technique scheme can well be accomplished the protection of gas leakage and leak gas, prevent that piston from declining and cause the damage of jack or jeopardize personal safety suddenly.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of Pneumatic jack of the utility model.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, clear and definite, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of Pneumatic jack, comprise load-carrying cylinder 101 and the cylinder 102 of exerting pressure, wherein, load-carrying cylinder and the cylinder of exerting pressure are cylindrical shape, bottom conducting, form U-shaped pipe, in two cylinder bodies, all there is piston, execute pressure cylinder piston central authorities and be provided with one way switch, control the air inlet cylinder that prevents from exerting pressure gives vent to anger outside cylinder body, in preferred embodiment of the present utility model, in the cylinder of exerting pressure of jack, one way switch 103 is set, spring 104, while inflating to the cylinder of exerting pressure, air pressure is pressed switch 103 downwards, open induction opening, can inflate inwards, in the time stopping inflating, gas in cylinder body is exerted pressure and the pulling force of spring is held on piston it, can prevent gas leakage.
Further improve and be, described Pneumatic jack, wherein, is provided with non-return switch 105 on the piston of described load-carrying cylinder, be reversed acanthoid, for support piston, prevents that piston from falling.Further, the utility model is also provided with non-return switch on the piston of load-carrying cylinder, in the time opening the non-return switch of piston, piston can only move up, and general knowledge is known, and it is along movement that hangnail rises, and while moving down, can touch hangnail, block and can not move.In the time closing non-return switch, piston can move freely in cylinder body, can, in the time of gas leakage, prevent that piston from declining suddenly, causes the damage of instrument or damages.
Further improve and be, described Pneumatic jack, wherein, the piston radius of described load-carrying cylinder is 10 times of piston radius of cylinder of exerting pressure, principle by jack can be known, in the time that the ratio of two piston radius is 10, can be in the power of load-carrying cylinder piston release 100N in the power of executing pressure cylinder piston and apply 1N.
In sum, on the piston of the utility model by the load-carrying cylinder at Pneumatic jack, non-return switch is set, the unexpected decline of piston while being used for preventing from leaking gas, be provided with one-way air inlet switch at the cylinder of exerting pressure, gas can only enter the cylinder of exerting pressure, can not leak to atmosphere from the cylinder of exerting pressure, when the utility model technique scheme can well be accomplished the protection of gas leakage and leak gas, prevent that piston from declining and cause the damage of jack or jeopardize personal safety suddenly.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or convert, all these improvement and conversion all should belong to the protection domain of the utility model claims.
