Description
Technical field
The utility model relates to a kind of lifting supporting mechanisms.
Background technique
Lifting supporting mechanism is generally used for supporting various workbenches, such as propping up in caravan parking caravan
Support, lifting supporting mechanism are generally fixedly mounted on workbench bottom, when needing to be supported workbench, driving part
Driving lifting supporting mechanism expansion, also allows for the support base decline on lifting supporting mechanism, until support base is resisted against ground
On, so that lifting supporting mechanism can be supported workbench, and when not needing to be supported workbench, it drives
Dynamic component driving lifting supporting mechanism collapses, and the support base also allowed on lifting supporting mechanism rises, until the lifting supports
Mechanism is collapsed in the bottom of workbench completely, so that workbench can be moved.And it is complete in lifting supporting mechanism
It collapses behind the bottom of workbench, since lifting supporting mechanism is shaken or due to the support base on lifting supporting mechanism
The reasons such as gravity are unfolded the lifting supporting mechanism voluntarily in rounding state, that is to say, that can make the lifting
Supporting mechanism malfunctions, this will bring security risk to the movement of workbench.
Utility model content
Technical problem to be solved by the utility model is to provide a kind of lifting supporting mechanisms, which is supported
Mechanism will not voluntarily be unfolded in complete rounding state, malfunction to avoid the lifting supporting mechanism.
In order to solve the above technical problems, lifting supporting mechanism provided by the utility model, it includes:
One lifting arm；
One support arm being hinged with lifting arm；
One support base being hinged with lifting arm；
One driving part for driving lifting arm to rotate to drive support base to go up and down；
Be provided with a magnet on the lifting arm or support arm, when the lifting supporting mechanism collapse completely and magnet be arranged
When on lifting arm, magnet is attracted with support arm；When the lifting supporting mechanism collapse completely and magnet be arranged on support arm
When, magnet is attracted with lifting arm.
Preferably, the lifting supporting mechanism further includes a mounting base, a guide holder and a sliding seat, driving part
It is mounted in mounting base, one end and the mounting base of support arm are hinged, and the other end and the lifting arm of support arm are hinged, guide holder
It is fixedly connected with mounting base, sliding seat is slidably disposed on guide holder, and driving part is for driving sliding seat in guide holder
Upper sliding, one end and the sliding seat of lifting arm are hinged, and the other end and the support base of lifting arm are hinged.
Preferably, the magnet setting is provided with a mounting plate on support arm, on support arm, it is provided on magnet
One connecting column, a bolt screw on connecting column for magnet to be locked on a mounting board.
After using the above structure, the utility model compared with prior art, is had the advantage that
The lifting supporting mechanism of the utility model, is provided with a magnet on lifting arm or support arm, in this way, in the lifting
After supporting mechanism collapses completely, support arm and lifting arm are collapsed, and support arm can be mutual by the suction of magnet with lifting arm
It is fixed, in this way, lifting arm can not also be made by shaking generated active force even if being shaken after lifting supporting mechanism collapses
Or support arm is detached from magnet, similarly, can not also make lifting arm or support in the gravity that lifting supporting mechanism collapses rear support
Arm is detached from magnet, in this way, allowing for the lifting supporting mechanism will not voluntarily be unfolded in complete rounding state, to avoid the lifting branch
Support mechanism malfunctions.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the cross-sectional view of the utility model.
Specific embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in Fig. 1, Fig. 2, the lifting supporting mechanism of the present embodiment, it includes a lifting arm 1, a support arm 2, one support
3, one driving part 4 of seat, a mounting base 6, a guide holder 7 and a sliding seat 8, driving part 4 are mounted in mounting base 6, are driven
Component 4 is a hydraulic cylinder, and mounting base 6 is fixed on the bottom of workbench, and one end and the mounting base 6 of support arm 2 are hinged,
The other end of support arm 2 is hinged with lifting arm 1, and the hinge joint of support arm 2 and lifting arm 1 is located at the middle position of lifting arm 1,
Support arm 2 can be relatively rotated with lifting arm 1 so that support arm 2 closes up or is unfolded with lifting arm 1, and guide holder 7 and mounting base 6 are solid
Fixed connection, guide holder 7 extend along the axis direction of the piston rod of hydraulic cylinder, and sliding seat 8 is slidably disposed on guide holder 7,
Sliding seat 8 can be slided along the axis direction of the piston rod of hydraulic cylinder, and hydraulic cylinder is used to that sliding seat 8 to be driven to slide on guide holder 7,
One end of lifting arm 1 is hinged with sliding seat 8, and the other end and the support base 3 of lifting arm 1 are hinged, in this way, working as Driven by Hydraulic Cylinder
Sliding seat 8 can drive lifting arm 1 and support arm 2 to rotate, so that the position of support base 2 increases when sliding on guide holder 7
Or reduce, referring to attached drawing 2, when Driven by Hydraulic Cylinder sliding seat 8 moves right, lifting arm 1 and support arm 2 are rotated, lifting arm 1
Upper end moves right, and support base 3 moves up at this time, which collapses, when Driven by Hydraulic Cylinder sliding seat 8 is to moving to left
When dynamic, lifting arm 1 and support arm 2 are rotated, and the upper end of lifting arm 1 is moved to the left, and support base 3 moves down at this time, the lifting branch
Support mechanism expansion.
A magnet 5 is provided on the support arm 2, when the lifting supporting mechanism collapses completely, magnet 5 and lifting arm
1 is attracted, and it is fixed with each other by magnet 5 with support arm 2 to allow for lifting arm 1 in this way, will not due to shaking or again
Power etc. is former so that the disengaging support arm 2 of lifting arm 1, is voluntarily unfolded, to avoid the lifting to avoid lifting arm 1 and support arm 2
Supporting mechanism malfunctions.
It is provided with a mounting plate 201 on support arm 2, a connecting column 501 is provided on magnet 5, connecting column 501 passes through installation
Plate 201, magnet 5 are resisted against a surface of mounting plate 201, and bolt 502 screws on connecting column 501, and bolt 50 is resisted against installation
Magnet 5 can be locked on mounting plate 201, make with this configuration by another surface of plate 201, such bolt 502
The installation and removal of magnet 5 are more convenient.
Explanation only is made that using preferable example with regard to the utility model above, but is not to be construed as to claim
Limitation, the structure of the utility model can have other variations, be not limited to above structure.In short, all in the only of the utility model
Made various change is within the protection scope of the present utility model in vertical scope of protection of the claims.
