The main body of the hydraulic oil cylinder comprises a cylinder body and a piston rod, wherein the piston rod is retractably arranged in the cylinder body; a piston is arranged at the bottom of the piston rod; the chamber of the cylinder body is divided into a cylinder body chamber and an auxiliary cylinder body chamber by the piston; an oil inlet pipe is arranged at the bottom of the cylinder body; one end of the oil inlet pipe is connected into the cylinder body chamber; a first oil return pipe and a second oil return pipe are arranged at the front end of the cylinder body; the first oil return pipe is arranged on the left side of the second oil return pipe; the first oil return pipe and the second oil return pipe are both connected to the auxiliary cylinder body chamber; a first one-way throttle valve is arranged on the second oil return pipe. The hydraulic oil cylinder has the benefits as follows: the design is novel, the structure is simple, the use is convenient, that the hydraulic oil cylinder is safer during daily use is ensured, damage to the hydraulic oil cylinder caused by collisions is avoided, and the hydraulic oil cylinder is practical and effective and is convenient to popularize and utilize.
Description
Technical field
The present invention relates to hydraulic jack and manufacture field, be specifically related to a kind of hydraulic jack with pooling feature.
Background technique
Along with the development of Chinese Industrialization process, the development of large-scale assembling manufacturing industry, oil cylinder, as the executive component of power, all plays an important role in all trades and professions, and its feature is exactly steady, High power output etc., oil cylinder kind general on market is a lot, but in broken engineering machinery, need the use of buffering hydraulic cylinder, and hydrovalve can not be used to meet the buffering of oil hydraulic cylinder, like this once hydrovalve breaks down, whole oil hydraulic cylinder will be destroyed.
Summary of the invention
It is simple that technical problem to be solved by this invention is to provide a kind of structure, and easy to use, cushioning effect significantly has the hydraulic jack of pooling feature.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of hydraulic jack of pooling feature, main body is by cylinder body, piston rod forms, it is characterized in that: described piston rod is telescopic is arranged on cylinder interior, a piston is provided with bottom described piston rod, inner chamber of cylinder block is split cylinder chamber and the secondary chamber of cylinder body by described piston, described cylinder base is provided with an oil inlet pipe, described oil inlet pipe one end is connected in cylinder chamber, described cylinder body front end is provided with the first return tube and the second return tube, the first described return tube is arranged on the left side of the second return tube, the first described return tube and the second return tube are all connected in the secondary chamber of cylinder body, the second described return tube is provided with an one-way throttle valve.
Described piston is provided with a seal ring, ensure that piston and inboard wall of cylinder block fit tightly, sealing is stronger; The secondary chamber of cylinder body arranges size two return tubes, and wherein the second return tube arranges one-way throttle valve.
The present invention is in use: hydraulic oil enters cylinder chamber by filler opening, in cylinder chamber, hydraulic oil can promote piston, impel piston rod protruding, hydraulic oil in the secondary chamber of cylinder body enters hydraulic system from the first return tube, because the second return tube place arranges one-way throttle valve, therefore can not be fuel-displaced, when piston movement is to the position of the first return tube, just the first return tube is blocked, now ring indent is sitting at the position of the first filler opening, play the effect of buffering and balance, also section hydraulic oil can be there is in cylinder body cavity on the left of piston and between the second return tube, hydraulic oil in this chamber cannot flow, slight compression can only be carried out by piston, the speed of stretching out of such piston rod will slow down greatly, thus play the effect of buffering, when piston rod pushes back, by the second return tube input hydraulic pressure oil, when constantly bouncing back, first return tube is again unimpeded, hydraulic oil in the secondary chamber of cylinder body first promotes piston, piston rod is to feeding back back.
The invention has the beneficial effects as follows: the present invention is novel in design, structure is simple, easy to use, ensure that hydraulic jack is in routine use, safer, and avoid collision and cause oil cylinder to damage, practicability and effectiveness, is convenient to utilization and extention.
Accompanying drawing explanation
Fig. 1 is inventive piston bar retracted mode figure;
Fig. 2 is that inventive piston bar stretches out phase diagram.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
As Fig. 1, shown in Fig. 2, a kind of hydraulic jack with pooling feature, main body is by cylinder body 1, piston rod 2 forms, piston rod 2 is telescopic is arranged on cylinder body 1 inside, a piston 3 is provided with bottom piston rod 2, inner chamber of cylinder block is split cylinder chamber 4 and the secondary chamber 5 of cylinder body by piston 3, an oil inlet pipe 6 is provided with bottom cylinder body 1, oil inlet pipe 6 one end is connected in cylinder chamber 4, cylinder body 1 front end is provided with the first return tube 7 and the second return tube 8, first return tube 7 is arranged on the left side of the second return tube 8, first return tube 7 and the second return tube 8 are all connected in the secondary chamber 5 of cylinder body, second return tube 8 is provided with an one-way throttle valve 9, after arranging like this, hydraulic oil enters cylinder chamber 4 by filler opening, in cylinder chamber, 4 hydraulic oil can promote piston 3, impel piston rod 2 protruding, the hydraulic oil in secondary 5 li, the chamber of cylinder body enters hydraulic system from the first return tube 7, because the second return tube place arranges one-way throttle valve 9, therefore can not be fuel-displaced, when piston 3 moves to the position of the first return tube 7, just the first return tube 7 is blocked, also hydraulic oil can be there is in cylinder body cavity between the first return tube 7 and the second return tube 8, the speed of stretching out of such piston rod 2 will slow down greatly, thus play the effect of buffering, when piston rod 2 pushes back, by the second return tube 8 input hydraulic pressure oil, when constantly bouncing back, first return tube 7 is again unimpeded, hydraulic oil in the secondary chamber 5 of cylinder body first promotes piston 3, piston rod 2 is to feeding back back, piston 2 is provided with a seal ring 10, ensure that piston 3 and inboard wall of cylinder block fit tightly, sealing is stronger.
More than show and describe basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
