Gas is supplied to the rear pore and enters the front cavity and the cavity through the ventilation blind hole and the air inlets to push the piston to move forward, so that the effect of pressure multiplying is achieved, it is unnecessary to supply the gas to all cavities and connect redundant pipelines in, and the whole cylinder is clean and tidy.

Description

The many times of cylinders of exerting oneself
Technical field
The utility model relates to cylinder and makes field, especially relates to a kind of many times of cylinders of exerting oneself.
Background technique
Along with socioeconomic development, cylinder is more and more applied in various industries by people, the Main Function of cylinder is that the Volume Changes by gas promotes piston movement the energy changing of gas volume is converted into mechanical energy, at present, some enterprises are being used a kind of many times of cylinders of exerting oneself, the benefit that this cylinder is used is to use a cylinder can reach the effect of pressure multiplier, main structure for installing a plurality of pistons on axle core, each piston has independently cavity to supply piston movement, by pass into gas on each cavity, a plurality of pistons are moved simultaneously reach pressure multiplier, but, the shortcoming of this cylinder is to need each cavity will pass into separately gas, will increase many pipelines, very inconvenient in maintenance, but when having, passing into separately gas likely there will be gas to enter not to be synchronous, so pressure multiplier effect reduces.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of many times of cylinders of exerting oneself that do not need independent air feed and there is no unnecessary pipeline.
The technical scheme in the invention for solving the technical problem is: a kind of many times of cylinders of exerting oneself, comprise an axle core, on axle core, be provided with a protecgulum and a bonnet, the inner side of described protecgulum is provided with the front cavity that an aluminum pipe is made, on the axle core of the inside of front cavity, be provided with secondary piston, between front cavity and bonnet, be provided with piston unit, described piston unit comprises the cavity that an aluminum pipe is made, on axle core in cavity, be provided with a piston, in one end of cavity, be provided with a dividing plate, on the tube wall of cavity, be provided with a spilehole; Described protecgulum is provided with front pore and is communicated with front cavity, and described bonnet is provided with posterior spiracle and is communicated with cavity; Described axle core central position is provided with ventilation blind hole, is provided with some inlet holes and is communicated with front cavity and cavity on the cylinder of ventilation blind hole.
Further concrete, described piston unit at least one.
Further concrete, described piston unit is 4.
Further concrete, described spilehole is positioned on the tube wall that cavity contacts with dividing plate.
Further concrete, described piston is provided with seal ring with the position that axle core contacts.
The beneficial effects of the utility model are: after having adopted said structure, by to posterior spiracle air feed, gas enters in front cavity and cavity by ventilation blind hole and inlet hole, promote piston-advance, can reach the effect of pressure multiplier, do not need each cavity to carry out independent air feed, also do not need to access unnecessary pipeline, whole cylinder is neatly clean.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, axle core; 2, protecgulum; 3, front pore; 4, front cavity; 5, secondary piston; 6, spilehole; 7, piston; 8, dividing plate; 9, cavity; 10, posterior spiracle; 11, bonnet; 12, seal ring; 13, ventilation blind hole; 14, inlet hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
A kind of many times of cylinders of exerting oneself as shown in Figure 1, comprise an axle core 1, on axle core 1, be provided with a protecgulum 2 and a bonnet 11, the inner side of described protecgulum 2 is provided with the front cavity 4 that an aluminum pipe is made, on the axle core 1 of the inside of front cavity 4, be provided with secondary piston 5, between front cavity 4 and bonnet 11, be provided with 4 piston units, described piston unit comprises the cavity 9 that an aluminum pipe is made, on axle core 1 in cavity 9, be provided with a piston 7, in one end of cavity 9, be provided with a dividing plate 8, on the tube wall of cavity 9, be provided with a spilehole 6; Described protecgulum 2 is provided with front pore 3 and is communicated with front cavity 4, and described bonnet 11 is provided with posterior spiracle 10 and is communicated with cavity 9; Described axle core 1 central position is provided with ventilation blind hole 13, is provided with some inlet holes 14 and is communicated with front cavity 4 and cavity 9 on the cylinder of ventilation blind hole 13; Described spilehole 6 is positioned on the tube wall that cavity 9 contacts with dividing plate 8; The position that described piston 7 contacts with axle core 1 is provided with seal ring 12.
The working principle of the many times of cylinders of exerting oneself: first, by posterior spiracle 10, give cylinder air feed, gas enters in cavity 9 by posterior spiracle 10, also enter in ventilation blind hole 13 simultaneously, gas is in inlet hole 14 enters into each cavity 9, now, continue air feed, piston 7 in each cavity 9 of gas push travels forward, gas at piston 7 front ends is discharged outside cylinder along spilehole 6 or front pore 3, owing to there being 7 pairs of axle cores of a plurality of pistons 1 to promote, make the pressure multiplier of the axle core 1 of cylinder, complete primary feed operation; When needs axle core 1 is replied, posterior spiracle 10 is air feed no longer, now, front pore 3 is carried out to air feed, gas enters into front cavity 4 by front pore 3, promote secondary piston 5 return motions, secondary piston 5 band moving axis cores 1 retreat, and axle core 1 drives all pistons 7 to retreat, and piston 7 pushes back the gas of its rear end by inlet hole 14 and ventilation blind hole 13, and air enters into the front end of piston 7 along spilehole 6, complete recovery operation one time.
It is emphasized that: be only preferred embodiment of the present utility model above, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
