Abstract
The invention discloses a hydraulic manual pump easy to operate. The hydraulic manual pump easy to operate comprises a valve body. A piston mechanism, an oil inlet channel and an oil outlet channel are arranged on the valve body, wherein the oil inlet channel and the oil outlet channel are connected with the piston mechanism. The oil inlet channel is connected with an oil inlet through an oil inlet control one-way valve. The oil outlet channel is connected with an oil outlet through an oil outlet control one-way valve. A piston pulling device is arranged on the piston mechanism. The piston pulling device comprises a fixing part arranged on the valve body, a pull rod with one end movably arranged on the fixing part, and a transmission rod used for being connected with the pull rod and the piston mechanism. The hydraulic manual pump is easy to operate.
Description
Technical field
The present invention relates to hydraulic system field, in particular it relates to a kind of easily operated hydraulic hand pump.
Background technology
The operation principle of easily operated hydraulic hand pump be people do work produce the pressure energy that changes mechanical energy is liquid. It is little that easily operated hydraulic hand pump has volume, is beneficial to the advantage carried, so the application of easily operated hydraulic hand pump is more and more extensive.
At present, hydraulic manual valve on the market its utilize piston mechanism to realize oil-feed and fuel-displaced. Need pressing or lift up the pressure head of piston mechanism, requiring great effort during operation.
Summary of the invention
The present invention is to solve that above-mentioned technical problem provides a kind of easily operated hydraulic hand pump, it is easily operated.
This invention address that the problems referred to above be the technical scheme is that
Easily operated hydraulic hand pump, including valve body, described valve body is provided with piston mechanism and the oil input channel being connected with piston machine and oil road, described oil input channel controls check valve by oil-feed and is connected with oil-in, described oil road is connected with oil-out by fuel-displaced control check valve, and described piston mechanism arranges piston pull unit; Pull bar that fixture that described piston pull unit includes being arranged on valve body, one end are movably arranged on fixture and the drive link for cylinder lever connecting rod and piston mechanism.
The present invention improves on the basis of existing technology, utilizes piston pull unit realize the pressing of piston or lift up. One end of pull bar is movably arranged on fixture, and the other end is as operating side. Lift up or pressing operation end, under the drive of drive link, lifting up or pressing of piston ram can be realized. Adjust the link position of drive link and pull bar or adjust the length of pull bar, according to mechanics principle, can to lifting up or the dynamics of pressing operation end is adjusted. Adopt this device, during operation, laborsaving.
As preferably, the two ends of described drive link are hinged with pull bar and piston mechanism respectively. Hinged mode is adopted to realize the connection of drive link and pull bar and piston rod, it is simple to the rotation of drive link.
As preferably, one end of described drive link is fixed on the stage casing of pull bar.
To sum up, the invention has the beneficial effects as follows:
The present invention utilizes piston pull unit realize the pressing of piston or lift up, and adjusts the length of the drive link link position with pull bar or adjustment pull bar, according to mechanics principle, can to lifting up or the dynamics of pressing operation end is adjusted, adopt this device, during operation, laborsaving.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Labelling and corresponding parts title in accompanying drawing: 1, valve body; 2, piston mechanism; 3, oil input channel; 4, oil road; 51, fixture; 52, pull bar; 53, drive link.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Embodiment 1:
A kind of easily operated hydraulic hand pump as shown in Figure 1, including valve body 1, described valve body 1 is provided with piston mechanism 2 and the oil input channel 3 being connected with piston mechanism 2 and oil road 4, described oil input channel controls check valve by oil-feed and is connected with oil-in, described oil road is connected with oil-out by fuel-displaced control check valve, and described piston mechanism 2 arranges piston pull unit; Pull bar 52 that fixture 51 that described piston pull unit includes being arranged on valve body 1, one end are movably arranged on fixture 51 and the drive link 53 for cylinder lever connecting rod 52 and piston mechanism 2. Fixture 51 and pull bar 52 can adopt hinged mode to realize connecting. The oil-feed of this device and fuel-displaced principle are same as the prior art. Fuel-displaced control check valve and oil-feed control the check valve flow direction to oil and limit.
Embodiment 2:
A kind of easily operated hydraulic hand pump as shown in Figure 1, the present embodiment optimizes on the basis of above-described embodiment, and namely the two ends of described drive link 53 are hinged with pull bar 52 and piston mechanism 2 respectively.
One end of described drive link 53 is fixed on the stage casing of pull bar 52. The length of drive link specifically can be arranged according to service condition, and drive link is fixed on the also adjustable of the position on pull bar. Adjust the length of drive link and drive link be fixed on the position on pull bar can to lifting up or the dynamics of pressing operation end is adjusted. Drive link is arranged on the stage casing of pull bar, the dynamics of half can be saved.
As it has been described above, the present invention can be realized preferably.
