Description
Technical field
The utility model relates to a kind of cylinders, and in particular to a kind of dual piston cylinder.
Background technique
Only one piston on general cylinder, and two piston rods are at most configured on piston, the length of piston rod can be made
Degree is fixed, therefore in stretching out stroke, and stroke control spacing can only at most control the distance for reaching a stroke,
Since the stroke of piston rod cannot effectively increase, cause two or more cylinders can only be used to be adjusted in mechanical structure
Component thus has biggish expenditure for the cost of production, leads to increased costs, and cylinder service efficiency is low.
Summary of the invention
To solve the above problems, having the multiple strokes of output the purpose of this utility model is to provide one kind and structure is reliable
Dual piston cylinder.
To achieve the above object, the utility model provides following technical solution: a kind of dual piston cylinder, including cylinder body,
Front cover and rear cover are equipped with secondary piston bar and rear piston rod in the cylinder body, are located at institute in secondary piston bar and rear piston rod
It states the intracorporal end of cylinder and is each configured with piston, the rear piston rod is hollow structure, and the hollow structure is from connected to it
Piston base is pierced by, and the telescopic end outer wall of the rear piston rod is equipped with externally threaded interconnecting piece, the telescopic end of the rear piston rod
Equipped with the connection hole slot being connect with tracheae, the front cover and it is described after cover the air inlet for being respectively equipped with and communicating with the cylinder body
Hole is arranged with cushion collar on the secondary piston bar and the rear piston rod respectively.
The front and back piston rod upper end is respectively equipped with step, and the cushion collar and described is successively arranged on the step
Piston after pass through nut tightening.
Annular groove corresponding with the cushion collar is respectively equipped on the front and rear covers, in the aperture position of the annular groove
Equipped with cushion seal circle.
This structure of the utility model, piston rod stretches out after can pushing after being ventilated by the air inlet of front cover, rear cover
Air inlet ventilation after can push the stretching of secondary piston bar, the hollow structure ventilation on rear piston rod can make front and back piston rod while stretch
Out, the adjustable purpose of cylinder stroke is just realized in this way, while being carried out in the piston rod telescopic process of front and back by cushion collar
Buffering, greatly improve the movable reliability and stability of piston rod, and improve service life, just realize in this way have it is defeated
Multiple strokes and the reliable technical effect of structure out.
The utility model is further described with reference to the accompanying drawings and detailed description.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of specific embodiment of the present invention.
Specific embodiment
The utility model is specifically described below by embodiment.
As shown in Figure 1, present embodiment discloses a kind of dual piston cylinder, including cylinder body 1, front cover 2 and rear cover 3, in cylinder
It is equipped with secondary piston bar 4 and rear piston rod 5 in body 1, is located at the end in cylinder body 1 in secondary piston bar 4 and rear piston rod 5 and is respectively configured
There is piston 6, rear piston rod 5 is hollow structure 55, which is pierced by from 6 bottom of piston connected to it, rear piston rod 5
Telescopic end outer wall be equipped with externally threaded interconnecting piece 52, connect by the interconnecting piece 52 with transmission parts, rear piston rod 5 stretch
End is equipped with connection hole slot 51, which connect with the tracheae on air pump, is respectively equipped on front cover 2 and rear cover 3 and cylinder
The air inlet 7 that body 1 communicates is arranged with cushion collar 8 on secondary piston bar 4 and rear piston rod 5 respectively.
Front and back piston rod (4,5) upper end is respectively equipped with step 9, leads to after cushion collar 8 and piston 6 are successively arranged on step 9
Nut 10 is crossed to screw.Secondary piston 6 can be thus made to avoid the feelings to collide with 2 inner sidewall of front cover during push
Condition, rear piston rod 5 also avoid colliding with rear cover 3, improve reliability of structure.
Front and rear covers are respectively equipped with annular groove 101 corresponding with cushion collar 8 on (2,3), in the aperture position of annular groove 101
Equipped with cushion seal circle 102.When cushion collar 8 reaches front and rear covers 3, it is directly entered in annular groove 101 and is abutted with cushion seal circle 102
Buffering refers to the effect of buffering significantly.
Through the above technical solutions, piston rod 5 stretches out after can pushing after being ventilated by the air inlet 7 of front cover 2, rear cover 3
Air inlet 7 ventilate after can push the stretching of secondary piston bar 4, the ventilation of hollow structure 55 on rear piston rod 5 can make front and back piston rod
(4,5) are stretched out simultaneously, just realize the adjustable purpose of cylinder stroke in this way, while in front and back piston rod (4,5) telescopic process
In buffered by cushion collar 8, greatly improve the movable reliability and stability of piston rod, and improve service life,
It just realizes in this way and has the multiple strokes of output and the reliable technical effect of structure.
