Abstract

The utility model discloses a kind of double-action single-stage cylinder, comprise cylinder barrel (2), two ends establish cylinder cap (4) and bottom (5) respectively, inside establish piston rod (3), suspension ring (1) are established at piston rod (3) two ends respectively, and piston (7), are characterized in, the rod chamber of described cylinder barrel (2) and rodless cavity establish left oil inleting port joint (18) and right fuel inlet neck (6) respectively, piston (7) bidirectional-movement; Seal between cylinder cap (4) and cylinder barrel (2), konisphere (8) of setting up defences between cylinder cap (4) and piston rod (3), 2 the first guide rings (9), an O type circle (10), piston rod oil sealing (11); Seal between piston (7) and piston rod (3), between piston (7) and cylinder barrel (2), establish 2 piston oil sealings (13) and the second guide ring (14); This double-action single stage hydraulic cylinder needs when overcoming single-acting single stage hydraulic cylinder retraction conduct oneself with dignity the defect pushed back by lifting thing, and ensure that each direction can be promoted by hydraulic oil, realization controls flexibly, substantially increases working efficiency.

Description

A kind of double-action single-stage cylinder
Technical field:
The utility model relates to oil hydraulic cylinder technical field, is a kind of double-action single-stage cylinder concretely, is applicable to car transporter and uses.
Background technique:
at present, use maximum single-acting single-stage cylinders to there is a problem, need during retraction by External Force Acting exactly, this brings very big inconvenience to application, and, there is the problem of hydraulic oil internal leakage, need to arrange a return opening at rod chamber specially, so that the hydraulic oil revealed is exported.
Summary of the invention:
The purpose of this utility model is the deficiency overcoming above-mentioned prior art, and provides a kind of double-action single-stage cylinder, needs the problem by External Force Acting and hydraulic oil internal leakage when mainly solving existing single-stage cylinder retraction.
The technical solution of the utility model is: a kind of double-action single-stage cylinder, comprise cylinder barrel, cylinder cap is established in cylinder barrel one end, the other end establishes bottom, establishes piston rod in cylinder barrel, and suspension ring are established in one end that piston rod stretches out cylinder cap, the other end in cylinder barrel establishes piston, its special way is, the rod chamber of described cylinder barrel and rodless cavity establish left oil inleting port joint and right fuel inlet neck respectively, and left oil inleting port joint and right fuel inlet neck lay respectively at the both sides of piston; Hydraulic fluid pressure is born at described piston two ends, realizes bidirectional-movement; Sealed by the 2nd O type circle between described cylinder cap and cylinder barrel, konisphere of setting up defences between described cylinder cap and piston rod, 2 the first guide rings, an O type circle, piston rod oil sealings; Sealed by the 3rd O type circle between described piston and piston rod, between piston and cylinder barrel, establish 2 piston oil sealings and the second guide ring.
Further, described piston rod and piston are locked by locking nut, and locking nut establishes cotter pin.
Compared with the prior art a kind of double-action single-stage cylinder described in the utility model has following good effect: 1, respectively arrange a filler opening at single-stage cylinder rod chamber and rodless cavity, oil hydraulic cylinder bidirectional-movement is made to use hydraulic control, easy to use, simultaneously, the hydraulic oil of internal leakage enters another chamber, do not need special discharge, because there was hydraulic oil in two chambeies originally; 2, the encapsulation scheme adopted between cylinder cap and piston rod and between piston and cylinder barrel has interior leakage and outward leakage amount is little, sealing part abrasion is little, piston rod runs the high feature of concentricity; 3, need when this double-action single stage hydraulic cylinder overcomes single-acting single stage hydraulic cylinder retraction conduct oneself with dignity the defect pushed back by lifting thing, ensure that each direction can be promoted by hydraulic oil, realization controls flexibly, substantially increases working efficiency.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
In order to better understand and implement, describe the utility model in detail below in conjunction with accompanying drawing; Illustrated embodiment, only for explaining the utility model, is not for scope of the present utility model.
Embodiment 1, see Fig. 1, needs to be processed into cylinder barrel 2 according to design, in cylinder barrel 2, install piston rod 3, and piston 7 is installed in piston rod 3 one end in cylinder barrel 2, and piston rod 3 and piston 7 are locked by locking nut 16, and have cotter pin 17 locking; Sealed by the 3rd O type circle 15 between piston 7 and piston rod 3, install 2 piston oil sealings 13 and the second guide ring 14 between piston 7 and cylinder barrel 2, play guiding and seal action, hydraulic fluid pressure can be born in piston 7 two ends, realizes bidirectional-movement; Install cylinder cap 4 in cylinder barrel 2 one end, cylinder cap 4 and cylinder barrel 2 are threaded connection, and are sealed between cylinder cap 4 and cylinder barrel 2 by the 2nd O type circle 12, install bottom 5 at cylinder barrel 2 the other end; Suspension ring 1 are installed in one end that piston rod 3 stretches out cylinder cap 4, install dust ring 8,2 the first guide rings 9, an O type circle 10, piston rod oil sealing 11 between cylinder cap 4 and piston rod 3, play sealing and dust-proof and leading role; Arrange left oil inleting port joint 18 and right fuel inlet neck 6 respectively at the rod chamber of cylinder barrel 2 and rodless cavity, left oil inleting port joint 18 and right fuel inlet neck 6 lay respectively at the both sides of piston 7.
A kind of double-action single-stage cylinder described in the utility model, during use, the suspension ring of oil cylinder by piston rod end are connected with car transporter with bottom, hydraulic oil enters cylinder barrel inside by left and right fuel inlet neck, promote piston movement, hydraulic fluid pressure can be born in piston two ends, realizes bidirectional-movement, right filler opening oil-feed then piston rod is stretched out, and left oil inleting port oil-feed then piston rod is retracted.
