Abstract
The utility model relates to a dual-rod air cylinder which comprises a front piston rod, a rear piston rod, a front cover, a rear cover, a cylinder barrel, a middle valve body, a guide sleeve and a support plate, wherein the front piston rod is connected with the rear piston rod; the front cover and the rear cover are respectively sleeved on the front piston rod and the rear piston rod; the middle valve body is sleeved on the rear piston rod, and is positioned between the front cover and the rear cover; the cylinder barrel is arranged on outer walls of the front cover, the middle valve body and the rear cover; the guide sleeve is sleeved on the front piston rod; and the support plate is sleeved on the outer wall of the guide sleeve, and is provided with a pull rod which is connected with the front cover and the rear cover. The dual-rod air cylinder is novel in structure, is reliable in performance, and solves the problem that the conventional single-piston-rod air cylinder is poor in loading capability, is unstable in running and the like during the using process.
Description
Technical field
The utility model relates to a kind of cylinder, relates in particular to a kind of pair of bar cylinder.
Background technique
Cylinder is all being brought into play great effect under a lot of places, and present on the market cylinder generally all is to be provided with a piston rod in the cylinder barrel, piston rod connects load and carries out work, the cylinder of this structure, and load capacity is relatively poor, and steady not in the running, bring many puzzlements to the user.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of two bar cylinders of simple in structure, reliable performance are provided.
For achieving the above object, the utility model adopts a kind of pair of bar cylinder, comprise the secondary piston bar, the back piston bar, protecgulum, bonnet, cylinder barrel, middle valve body, guide sleeve and dunnage, described secondary piston bar is connected with the back piston bar, protecgulum and bonnet are set in respectively on secondary piston bar and the back piston bar, middle valve body is set on the back piston bar and between protecgulum and bonnet, cylinder barrel is arranged on protecgulum, on the outer wall of middle valve body and bonnet, guide sleeve is set on the secondary piston bar, dunnage is set in the outer wall of guide sleeve, and arranging on the described dunnage has respectively the pull bar that links to each other with bonnet with protecgulum.
The utility model further arranges again, and each parts joint is provided with Sealing.
In sum, the beneficial effects of the utility model are: two bar air cylinder structures are novel, reliable performance, solved the problems such as the load capacity that traditional single piston rod cylinder in use occurs is poor, operation is not steady.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
