Abstract
The utility model discloses a hydraulic manual pump, which comprises the following components: a valve body, the oil feed that is provided with the piston mechanism on the valve body and links to each other with the piston machine is said and is gone out the oil duct, the oil feed is said and is connected with the oil inlet through oil feed control check valve, it is connected with the oil -out through the control check valve that produces oil to go out the oil duct, set up piston pulling device on the piston mechanism, piston pulling device including set up mounting on the valve body, one end activity setting on the mounting the pull rod and be used for connecting the transfer line of pull rod and piston mechanism, it is easily operated.
Description
Technical field
This utility model relates to hydraulic system field, in particular it relates to a kind of hydraulic hand pump.
Background technology
The operation principle of hydraulic hand pump be people do work produce the pressure energy that changes mechanical energy is liquid.It is little that hydraulic hand pump has volume, is beneficial to the advantage carried, so the application of 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.
Utility model content
This utility model provides a kind of hydraulic hand pump to solve above-mentioned technical problem, and it is easily operated.
The technical scheme in the invention for solving the above technical problem is:
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.
This utility model 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 beneficial effects of the utility model are:
This utility model 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 structural representation of the present utility model.
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 this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, 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 this utility model protection.
Embodiment 1:
A kind of 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 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, this utility model can be realized preferably.
