Abstract
The utility model relates to a cylinder, to be specific a double-rod cylinder. The utility model is characterized in that two parallel piston rods are disposed in a cylinder; ends of two piston rods are connected with a piston, and the other ends of the two piston rods are connected together with a front plate through an inner hexagonal screw; one inner side of the cylinder is provided with a rear cover, and the other inner side is provided with a front cover. Compared with the prior art, the two piston rods can move in and out at the same time, and in the front of the two rods is disposed a front support plate, which can effectively increase the applied force area of the cylinder and the loading surface, thereby the double-rod cylinder provided in the utility model has advantages of stable function, reliable performance, and safe use.
Description
Technical field
The utility model relates to a kind of cylinder, specifically provides a kind of pair of bar cylinder.
Background technique
Cylinder under the prior art, general structure are to be provided with a piston rod in the cylinder barrel, and piston rod connects load and carries out work, and the cylinder of this structure not only load capacity is relatively poor, and running is steady inadequately.
Summary of the invention
The utility model is at above problem, and a kind of pair of bar cylinder is provided, and it is by being provided with two parallel piston rods in same cylinder barrel, and two piston rods are connected header board jointly, makes it increase traveling comfort, and has strengthened load capacity.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of pair of bar cylinder comprises cylinder barrel, is provided with two parallel piston rods in the described cylinder barrel, described two piston rod one ends connect piston, one end is connected on the header board jointly by hexagon socket head cap screw, and the inner side of described cylinder barrel is provided with bonnet, and opposite side is provided with protecgulum.
The arranged outside of protecgulum and bonnet has jump ring.
Be provided with dust ring and axle sleeve between piston rod and the protecgulum.
Be provided with protecgulum O type circle between protecgulum and the cylinder barrel.
The piston both sides are provided with crashproof pad.
Be provided with C type circle and wear-resisting band between piston and the cylinder barrel.
Be provided with bonnet O type circle between bonnet and the cylinder barrel.
Cylinder barrel the place ahead is provided with the adjustment screw.
A kind of pair of bar cylinder of the present utility model, it is exclusively used in the support and the lifting of light-duty working platform, cylinder barrel is long strip twin-tub footpath, and be provided with the magnetic switch slot, can carry out stroke location accurately, two piston rod synchronous operations, the flex resistance and the torsional rigid of height are provided, guarantee the working life and the remarkable steering capability of cylinder, compared with prior art, it has the advantages that to operate steadily, double piston-rod is with advancing with going out, front end is furnished with the support header board, has effectively enlarged the lifting surface area of cylinder and load surface, more reliable performance, use safer.
