Abstract
The invention relates to the technical field of air cylinders, in particular to an improved structure of an air cylinder. The improved structure comprises a cylinder body, a piston and a piston rod. A front cover with an inflating hole is arranged at the front end of the cylinder body, and a rear cover with an exhaust hole is arranged at the rear end of the cylinder body. The piston is arranged in the cylinder body slidably, and one end of the piston rod penetrates a through hole in the front cover to be fixedly connected with the piston. A return spring is arranged between the inner side of the piston and the rear cover, a guide spring holder is fixedly arranged on the inner side of the piston, and one end of the return spring is sleeved on the guide spring holder. Jamming of the return spring during running is avoided, and application field and range of the air cylinder in the improved structure are broadened effectively.
Description
Technical field
The present invention relates to cylinder technical field, particularly a kind of improvement structure of cylinder.
Background technique
Cylinder is as conventional machinery component unit, and common by people, it is widely used in the every field such as medical apparatus, furniture and auto parts machinery, generally usings oil, gas or gas mixture as transmission medium in cylinder.Return spring in its cylinder body of existing cylinder, when return spring is longer, piston extruding return spring, usually there is stuck phenomenon in return spring, affects cylinder operation, so inevitable application and application area that affects cylinder.Therefore existing cylinder is carried out to structure innovation to be necessary in fact.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, provide a kind of simple in structure, return spring is without the improvement structure of the cylinder of stuck phenomenon.
For achieving the above object, the present invention is by the following technical solutions:
The improvement structure of a kind of cylinder of the present invention, comprise cylinder body, piston and piston rod, described cylinder body front end is provided with protecgulum, protecgulum is provided with air-filled pore, described rear end of the cylinder block is provided with bonnet, bonnet is provided with exhaust port, described piston is slidably located in cylinder body, described piston rod one end is fixedly connected with piston through the through hole in protecgulum, between described piston inner side and bonnet, be provided with return spring, described piston inner side is fixed with guide spring seat, and described return spring one end is set on guide spring seat.
Further, described cylinder body is provided with connection set.
Wherein, described connection set comprises connecting head and the connecting rod that is fixed on connecting head, and described connecting head is bolted in rear end of the cylinder block.
Further, between the through hole in described piston rod and protecgulum, be provided with dust ring.
Adopt after said structure, beneficial effect of the present invention is: between piston of the present invention inner side and bonnet, be provided with return spring, described piston inner side is fixed with guide spring seat, described return spring one end is set on guide spring seat, arrange like this, can effectively avoid return spring to occur stuck phenomenon in the process of compressing and stretching.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, the improvement structure of a kind of cylinder of the present invention, comprises cylinder body 5, and piston 4 and piston rod 1 are also cylinder body 5, and piston 4 and piston rod 1 form agent structure of the present invention.
Described cylinder body 5 front ends are provided with protecgulum 2, and protecgulum 2 is provided with air-filled pore 3, and described cylinder body 5 rear ends are provided with bonnet 12, and bonnet 12 is provided with exhaust port 6.Described piston 4 is slidably located in cylinder body 5, and piston 4 outer walls are provided with seal ring, with and cylinder body 5 inwalls between form effective sealing, effectively increase air-tightness of the present invention.
Described piston rod 1 one end is fixedly connected with piston 4 through the through hole in protecgulum 2.
Between described piston 4 inner sides and bonnet 12, be provided with return spring 11, described piston 4 inner sides are fixed with guide spring seat 10, and described return spring 11 one end are set on guide spring seat 10.In the process of described return spring 11 compressions and stretching, extension, guide spring seat 10 can be realized good leading role to return spring 11, can effectively avoid return spring 11 to occur stuck phenomenon, has greatly improved quality of the present invention.
Described cylinder body 5 is provided with connection set, for connecting between parts.Described connection set comprises connecting head 7 and the connecting rod 8 that is fixed on connecting head 7, and described connecting head 7 is bolted in cylinder body 5 rear ends.
Between through hole in described piston rod 1 and protecgulum 2, be provided with dust ring 9, to prevent that dust from entering in the present invention, affect normal operation of the present invention.
The above is only better embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
