Description
Technical field
The present invention relates to mechanical field, more particularly, to a kind of four-pull-rod hydraulic jack.
Background technology
The hydraulic industry in China passes through the development of nearly 50 years, has had quite production strength and technical merit, the primary demand of economic development can be substantially met, wherein the supporting rate of great outfit has reached more than 60%.The especially Fast Growth of downstream industry in the past 10 years, has actively promoted the growth of Hydraulic Industry.Oil cylinder is one of product the most ripe in China's hydraulic product.Industry keeps rapid growth for many years, has formd more ripe supply chain, has possessed larger market scale.Manually supercharging stalk makes hydraulic oil enter oil cylinder by a check valve, at this moment can not return back to come again because of the reason for individual event valve into the hydraulic oil of oil cylinder, force cylinder rod upward, then continue to make hydraulic oil constantly enter hydraulic cylinder in workmanship, constantly rise like this, hydraulic valve is turned on when drop, hydraulic oil is returned to fuel tank, this is simplest operation principle.Still cause problems at work, such as reveal energy, hydraulic oil, pollute periphery working environment, influence other elements normal work.
The content of the invention
The present invention is in order to solve present problems, a kind of four-pull-rod hydraulic jack is provided for this, including cylinder bottom, cylinder bottom connects cylinder body, there is piston in cylinder body, there is piston rod in piston, the other end is provided with cylinder top, there is the first guide sleeve in cylinder top, the first guide sleeve is externally provided with the second guide sleeve, and the first sealing ring is set at the mesopore of cylinder body and piston rod, there is four-pull-rod to connect between cylinder bottom and cylinder top, the support frame setting up and down between piston and cylinder body, the second sealing ring is set in piston and piston rod interface, and dust cover is set in piston rod and the second guide sleeve gap location.Preferably, support frame as described above respectively sets two up and down.It is reactionless during import when piston rod movement preferably, the sealing ring is quality of rubber materials, piston rod will be bonded during outlet.
The beneficial effects of the invention are as follows：
In hydraulic cylinder works; motion between piston and piston rod causes to reveal unavoidably; but after having the first sealing ring and the second sealing ring; by the effective operating efficiency for improving hydraulic cylinder; avoid leakage phenomenon; ensure job stability; increase the service life and operating efficiency of hydraulic jack; the setting of support frame is for vibrations caused by when stable plunger and piston rod work; it is unlikely to deform skew, increase its service life, improve stability; the setting of dust cover will play dustproof effect, protection element work outside piston rod and the second guide sleeve.
Brief description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
Fig. 1 is the front view of the present invention.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, in addition to mutually exclusive feature and/or step, can combine in any way.
Any feature disclosed in this specification, unless specifically stated otherwise, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature is an example in a series of equivalent or similar characteristics.
As shown in Fig. 1 a kind of four-pull-rod hydraulic jack, including cylinder bottom, cylinder bottom connects cylinder body, there is piston in cylinder body, there is piston rod in piston, the other end is provided with cylinder top, there is the first guide sleeve in cylinder top, first guide sleeve is externally provided with the second guide sleeve, first sealing ring is set at the mesopore of cylinder body and piston rod, has four-pull-rod to connect between cylinder bottom and cylinder top, the support frame setting up and down between piston and cylinder body, the second sealing ring is set in piston and piston rod interface, dust cover is set in piston rod and the second guide sleeve gap location.Preferably, support frame as described above respectively sets two up and down.It is reactionless during import when piston rod movement preferably, the sealing ring is quality of rubber materials, piston rod will be bonded during outlet.
The beneficial effects of the invention are as follows：
In hydraulic cylinder works; motion between piston and piston rod causes to reveal unavoidably; but after having the first sealing ring and the second sealing ring; by the effective operating efficiency for improving hydraulic cylinder; avoid leakage phenomenon; ensure job stability; increase the service life and operating efficiency of hydraulic jack; the setting of support frame is for vibrations caused by when stable plunger and piston rod work; it is unlikely to deform skew, increase its service life, improve stability; the setting of dust cover will play dustproof effect, protection element work outside piston rod and the second guide sleeve.
The invention is not limited in foregoing embodiment.The present invention expands to any new feature disclosed in this manual or any new combination, and disclose any new method or process the step of or any new combination.
