Abstract
The utility model relates to a safety air cylinder, which comprises a front end cover, a cylinder tube, a piston rod, a piston and a back end cover, wherein the front end cover is connected with one end of the cylinder tube, the other end of the cylinder tube is connected with the back end cover, the piston rod passes through the front end cover to be connected with the piston, the piston is arranged inside the cylinder tube, in addition, the inner wall of the cylinder tube adopts a sliding matching connection mode for connection, and two fixing rings are arranged on the inner wall of the cylinder tube and are respectively arranged at two ends of the piston. Through adopting the structure that the fixing rings are arranged on the inner wall of the cylinder tube and at two sides of the piston, under the condition of excessive pressure, the piston is protected from excessively butting the front end cover or the back end cover, the explosion of the air cylinder is prevented, and the safety factor in the work process is improved.
Description
Technical field
The utility model relates to a kind of pneumatic apparatus, relates in particular to a kind of safety air cylinder.
Background technique
Cylinder is a kind of pneumatic apparatus, and common cylinder comprises the parts such as cylinder body, piston, piston rod first, but this traditional cylinder is when work, because pressure is excessive, cause piston to prop up front cover or rear end cover, cause cylinder to pop, potential safety hazard occurs.
The model utility content
In view of this, be necessary to provide a kind of safety air cylinder.
The utility model is to realize like this, a kind of safety air cylinder, comprise front cover, cylinder barrel, piston rod, piston, rear end cover, described front cover is connected with an end of cylinder barrel, the other end of described cylinder barrel is connected with described rear end cover, described piston rod passes described front cover and is connected with described piston, described piston is located at the inside of described cylinder barrel, and take sliding Placement of joining to be connected with described inner wall of cylinder, described inner wall of cylinder is provided with two retaining rings, and described two retaining rings are located at respectively the both sides of described piston.
Further, be provided with steel bushing between described front cover and the piston rod, described steel bushing is embedded on the described front cover.
Further, be provided with seal ring one between described piston and the cylinder barrel, described seal ring one is located on the piston, described seal ring one be shaped as " Y " shape.
Further, be provided with seal ring two between described piston rod and the described piston, described seal ring two is located on the described piston.
Further, described seal ring two is shaped as " O " shape.
The advantage of the safety air cylinder that the utility model provides is: by on the inwall of cylinder barrel; and the both sides at piston arrange retaining ring, and in the excessive situation of pressure, the protection piston can excessively not prop up front cover or rear end cover; the blast that prevents cylinder produces, and has improved the safety coefficient in the work.
Description of drawings
Fig. 1 is the structural representation of the utility model safety air cylinder.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also Fig. 1, Fig. 1 is the structural representation of the utility model safety air cylinder 10.
Described safety air cylinder 10 comprises front cover 5, cylinder barrel 6, piston rod 2, piston 3, rear end cover 9, described front cover 5 is connected with an end of cylinder barrel 6, the other end of described cylinder barrel 6 is connected with described rear end cover 9, described piston rod 2 passes described front cover 5 and is connected with described piston 3, described piston 3 is located at the inside of described cylinder barrel 6, and take sliding Placement of joining to be connected with described cylinder barrel 6 inwalls, described cylinder barrel 6 inwalls are provided with two retaining rings 1, and described two retaining rings 1 are located at respectively the both sides of described piston 3.
Be provided with steel bushing 8 between described front cover 5 and the piston rod 2, described steel bushing 8 is embedded on the described front cover 5, be provided with seal ring 1 between described piston 3 and the cylinder barrel 6, described seal ring 1 is located on the piston 3, described seal ring 1 be shaped as " Y " shape, be provided with seal ring 27 between described piston rod 2 and the described piston 3, described seal ring 27 is located on the described piston 3, described seal ring 27 be shaped as " O " shape.
In sum; the advantage of the safety air cylinder that the utility model provides is: by on the inwall of cylinder barrel; and the both sides at piston arrange retaining ring; in the excessive situation of pressure; the protection piston can excessively not prop up front cover or rear end cover; the blast that prevents cylinder produces, and has improved the safety coefficient in the work.
