Abstract
The utility model relates to a cylinder comprising a front cover, a rear cover, a cylinder barrel, valve cores, a piston and a piston rod, the front cover and the rear cover are fixedly arranged on a left end face and a right end face of the cylinder barrel, the front cover and the rear cover are fastened by a pull rod, the piston is arranged in the cylinder barrel, a plastic magnet strip, a wear strip and a sealing ring are arranged between an outer end face of the piston and an inner wall of the cylinder barrel, the piston rod penetrates the front cover in an axial direction and is arranged in the cylinder barrel, the piston rod is connected with the piston in the cylinder barrel, the valve core is fixedly arranged on the rear cover, a position of the piston rod in the cylinder barrel is sleeved with a long matching buffer sleeve, and an end of the long buffer sleeve abuts against the piston. The cylinder employs the long buffer sleeve, buffer performance of the cylinder in motion process is greatly improved, and buffer failure is prevented; and a conventional dustproof sealing ring is improved as a polyurethane dustproof sealing ring with novel structure, and service life and the dustproof capacity of the cylinder are improved.
Description
Technical field
The utility model relates to a kind of cylinder.
Background technique
Utilize the thrust of air pressure to do straight line motion during the cylinder operation, certain inertia when moving back and forth, piston is arranged, can not stop timely, so the end cap at cylinder two ends is clashed in the meeting that just cannot avoid, the main purpose of gas buffering has: 1, protection loads on the damage that is not subject to serious shock when putting in place and causes machine, 2, end cap, the piston of protection cylinder, avoid end cap to receive that directly the Fast Collision of piston causes damaged hidden danger; And at present the effect brought of the damping device of cylinder is unsatisfactory on the market, moreover, be used for preventing that the dust-proof seal ring that the impurity such as dust, greasy dirt enter cylinder from not playing good dust-proof effect yet.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of good buffer effect, cylinder that dirt exclusion capabilities is strong are provided.
for achieving the above object, the utility model adopts a kind of cylinder, comprise protecgulum, bonnet, cylinder barrel, spool, piston and piston rod, described protecgulum and bonnet are fixedly installed on the left side of cylinder barrel, right both ends of the surface, and fastening by pull bar, piston is arranged in cylinder barrel, be provided with between the exterior edge face of piston and inner wall of cylinder and mould magnetic stripe, wear-resistant strip and seal ring, piston rod is to passing that protecgulum is arranged in cylinder barrel and being connected with piston in cylinder barrel, described spool is fixedly installed on bonnet, piston rod is positioned at the adaptive long cushion collar that is arranged with in position of cylinder barrel, the setting that offsets of one end of long cushion collar and piston.
The utility model is under the length that does not change the cylinder external overall, to cylinder interior just change, lengthened cushion collar, make the cushioning effect distance lengthen 1.3～1.5 times on the basis of former cushion collar, improved greatly the shock-absorbing capacity of cylinder in movement process, avoided the buffer invalidation that originally is prone to, made the performance of cylinder integral body more stable, used safer.
The utility model further arranges again, the position that is connected with piston rod in the exterior edge face of protecgulum is provided with a dust-proof seal ring, top with outer wall in the middle of the outer wall of dust-proof seal ring all is formed with projection, upper/lower terminal face at dust-proof seal ring respectively is formed with a groove, the interior edge face annular of dust-proof seal ring is provided with a dovetail groove, and described dust-proof seal ring adopts polyurethane material to make.
On market, common cylinder is put a rubber seal in the protecgulum that piston rod stretches back and forth, to prevent in a dust, greasy dirt field inlet casing, this rubber dust-proof seal ring can prevent slight pollution, but still can lose efficacy in serious dust, serious oil pollution environment, the utility model adopts the polyurethane dust-proof seal ring, reliable in structure, sealability is stable, has well solved the problem of dustproof inefficacy.
In sum, the beneficial effects of the utility model are: by lengthening cushion collar, improved greatly the shock-absorbing capacity of cylinder in movement process, avoided buffer invalidation; The traditional dust-proof seal ring of script is improved as the polyurethane dust-proof seal ring of novel structure, has improved working life and the dirt exclusion capabilities of cylinder.
