Abstract
The invention relates to a single-acting plunger type hydraulic cylinder which comprises a cylinder body, a plunger, a guide sleeve, a seal ring and a press cover. A through hole is arranged at one end of the cylinder body, the press cover is arranged at the other end of the cylinder body, one end of the plunger penetrates through the press cover to penetrate into the cylinder body, and the guide sleeve and the seal ring are respectively arranged between the press cover and the plunger. The single-acting plunger type hydraulic cylinder is characterized in that a guide block is arranged at the end of the plunger penetrating into the cylinder body. The single-acting plunger type hydraulic cylinder is convenient to use, suitable for horizontal or vertical installation and long in service life.
Description
Technical field
The present invention relates to a kind of oil hydraulic cylinder, specifically, relate to a kind of single-acting plunger type oil hydraulic cylinder.
Background technique
Plunger type cylinder, it can only realize the motion of a direction, backhaul leans on gravity or spring force or other power to promote.In order to obtain bidirectional-movement, be generally the layout of, repercussion is used.Plunger leads by guide sleeve, and plunger does not contact with cylinder body.Plunger is an end capacity compression, for guaranteeing plunger case enough thrust and stability is arranged, and plunger is generally thicker, and weight is bigger, is prone to when level is installed produce uneven wear, so the unsuitable level of oil hydraulic cylinder is installed.And in some cases, need the oil hydraulic cylinder level be installed, so just shortened the working life of oil hydraulic cylinder greatly.Therefore, need a kind of new technological scheme to solve above-mentioned technical problem.
Summary of the invention
The purpose of this invention is to provide a kind of single-acting plunger type oil hydraulic cylinder, this oil hydraulic cylinder not only can level be installed, but also can vertically install, and is easy to use, increase working life.
The technological scheme that the present invention adopts is:
The single-acting plunger type oil hydraulic cylinder; Comprise cylinder body, plunger, guide sleeve, seal ring and gland; One end of said cylinder body is provided with through hole, the other end is provided with gland; One end of said plunger passes gland and extends in the cylinder body, and said guide sleeve and seal ring are separately positioned between gland and the plunger, and the end that said plunger extends in the cylinder body is provided with guide pad.
Further, said guide pad is provided with a plurality of vents.
The present invention is provided with guide pad on the end in plunger extends cylinder body, and this guide pad contacts with the inwall of cylinder body, plunger is played the effect of supporting and leading.When oil hydraulic cylinder is installed in level, can not increase the working life of plunger because of extending plunger in the cylinder body under own wt and deform yet.
Advantage of the present invention is: easy to use, be applicable to level or vertical the installation, and long service life.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present invention.
Wherein: 1, cylinder body, 2, plunger, 3, guide sleeve, 4, seal ring, 5, gland, 6, through hole, 7, guide pad, 8, vent.
Embodiment
As shown in Figure 1, the single-acting plunger type oil hydraulic cylinder comprises cylinder body 1, plunger 2, guide sleeve 3, seal ring 4 and gland 5; One end of cylinder body 1 is provided with through hole 6, the other end is provided with gland 5; One end of plunger 2 passes gland 5 and extends in the cylinder body 1, and guide sleeve 3 and seal ring 4 are separately positioned between gland 5 and the plunger 2, and the end that plunger 2 extends in the cylinder body 1 is provided with guide pad 7; This guide pad 7 contacts with the inwall of cylinder body 1; Plunger 2 is played the effect of supporting and leading,, on guide pad 7, establish to a plurality of vents 8 for balance plunger 2 and 1 pressure of cylinder body.
Claims (2)
1. single-acting plunger type oil hydraulic cylinder; Comprise cylinder body, plunger, guide sleeve, seal ring and gland; One end of said cylinder body is provided with through hole, the other end is provided with gland; One end of said plunger passes gland and extends in the cylinder body, and said guide sleeve and seal ring are separately positioned between gland and the plunger, it is characterized in that: the end that said plunger extends in the cylinder body is provided with guide pad.
