Summary of the invention
The present invention provides a kind of hydraulic manual pump structure to solve the problems of the technologies described above, and it is easy to operation and is convenient to storage.
The present invention's adopted technological scheme that solves the problem is:
A kind of hydraulic manual pump structure, comprise valve body, the oil input channel described valve body being provided with piston mechanism and be connected with piston mechanism and oil road, described oil input channel controls one-way valve by oil-feed and is connected with filler opening, described oil road is connected with oil outlet by fuel-displaced control one-way valve, described piston mechanism is arranged piston pull unit; Described piston pull unit comprises the fixed block be arranged on valve body, one end is movably arranged on pull bar on fixed block and for the drive link of cylinder lever connecting rod and piston mechanism, described pull bar is flexible rod, described pull bar comprises the many telescopic pipes be mutually socketed, described telescopic pipe is provided with the escapement preventing the telescopic pipe of internal layer from departing from adjacent outer telescopic pipe, described drive link is movably arranged on the outermost telescopic pipe of pull bar.
The present invention improves on the basis of existing technology, utilize piston pull unit realize piston pressing or on carry.One end of pull bar is movably arranged on fixed block, and the other end is as operating end.On carry or pressing operation end, under the drive of drive link, can realize piston ram on carry or press.The link position of adjustment drive link and pull bar or adjust the length of pull bar, according to mechanics principle, can to above to carry or the dynamics of pressing operation end adjusts.Adopt this device, during operation, laborsaving.To the dynamics size tension member effect length that pull bar applies during operation, in order to laborsaving, it is longer that pull bar is generally arranged.But, when pull bar is longer, be not easy to storage and transport.The present invention also improves bracing structure, and pull bar is set to Collapsible structure, utilizes the tensile elongation of escapement to telescopic pipe to limit, avoids coming off of telescopic pipe.Pull bar freely can adjust length according to service condition, and the used time can not shorten yet, and is convenient to storage, takes up room little after storage, is convenient to transport.Drive link be arranged on outermost telescopic pipe, one end of telescopic pipe is movably connected on fixed block, makes the length change of pull bar can not affect drive link fixed position, strengthens the stability of drive link structure.
As preferably, from skin to internal layer, its length reduces the length of described telescopic pipe gradually, and described escapement comprises flexible guide groove and fixture block, and the fixture block on the telescopic pipe of internal layer is stuck in the flexible guide groove of the telescopic pipe of adjacent outward layer.Escapement utilizes the cooperation of flexible guide groove and fixture block to realize, and fixture block is positioned at flexible guide groove, and one end of guide groove is closed, and can prevent coming off of telescopic pipe.
Further, in order to improve the flexible flatness of telescopic pipe, described flexible guide groove is provided with two flexible guide grooves, and two flexible guide grooves parallel.
As preferably, the two ends of described drive link respectively with pull bar and piston mechanism hinged.Adopt hinged mode to realize the connection of drive link and pull bar and piston rod, be convenient to the rotation of drive link.
To sum up, the invention has the beneficial effects as follows:
1, the present invention utilize piston pull unit realize piston pressing or on carry, the link position of adjustment drive link and pull bar or adjust the length of pull bar, according to mechanics principle, can to above to carry or the dynamics of pressing operation end adjusts, adopt this device, during operation, laborsaving.
2, pull bar of the present invention is Collapsible structure, and it freely can adjust length according to service condition, and the used time can not shorten yet, and is convenient to storage, takes up room little after storage, is convenient to transport.
