Abstract
Anti-turning over presses hand jack, comprise body, hydraulic oil pump, handle, the rising arm of hinge strip pallet and handle on the wallboard of described body, described hydraulic oil pump is arranged on the base plate of described body, described handle is connected with the pump core of described hydraulic oil pump by lift, described pump core with press hand and be coupling, and the top end face of described pump core rolls with the roller pressed on the roller bearing pin of hand of jack and is connected, position near lift on the wallboard of described body is provided with a pull bar, the position of the corresponding pull bar in two ends of the bottom of described lift is provided with and lift can be made to keep the lift block of vertical state when jack does not work, described lift block is resisted against on described pull bar.In use, lift block avoids the generation of the easily damaged situation of rubber back-up ring to the utility model, and when handle pushes away forward, lift block is not easily extruded distortion, and extend the service life of jack, structure is simple.
Description
Technical field
The utility model relates to a kind of anti-turning over and presses hand jack.
Background technology
When traditional jack does not work, make lift keep the mode of vertical state to be: by the method at pull bar two ends socket rubber back-up ring, spacing to lift, make lift keep vertical state (as Fig. 1 a, 1b and 1c).But in use, because rubber back-up ring is easily damaged, and when handle pushes away forward, rubber back-up ring is easily extruded distortion, turn over before causing lift to live, make pump core under the effect of stage clip, live outer bullet, exceed forced stroke, even make pump core eject the pump housing, cause the inefficacy of jack.
Summary of the invention
In order to the lift solving current jack keeps the problems referred to above of existing in the method for vertical state, the utility model to provide a kind of anti-turning over to press hand jack, avoid the adverse consequences that rubber back-up ring causes because of crimp.
The technical solution adopted in the utility model is:
Anti-turning over presses hand jack, comprise body, hydraulic oil pump, handle, the rising arm of hinge strip pallet and handle on the wallboard of described body, the front and back ends of the base plate of described body installs front wheel spindle and hind axle respectively, and front-wheel is equipped with at the two ends of described front wheel spindle, the two ends of hind axle are furnished with trailing wheel, described hydraulic oil pump is arranged on the base plate of described body, described handle is connected with the pump core of described hydraulic oil pump by lift, described pump core with press hand and be coupling, and the top end face of described pump core rolls with the roller pressed on the roller bearing pin of hand of jack and is connected, it is characterized in that: the position near lift on the wallboard of described body is provided with a pull bar, the position of the corresponding pull bar in two ends of the bottom of described lift is provided with and lift can be made to keep the lift block of vertical state when jack does not work, described lift block is resisted against on described pull bar.
The face that described lift block contacts with pull bar has the shape matched with the outside face of pull bar.
The beneficial effects of the utility model are: in use, and lift block avoids the generation of the easily damaged situation of rubber back-up ring, and when handle pushes away forward, lift block is not easily extruded distortion, and extend the service life of jack, structure is simple.
