Description
Technical field
The present invention relates to Architectural Equipment technical field, particularly relate to the elevating mechanism of a kind of workbench supporting leg.
Background technology
Along with the raising day by day of living standard, people are for house and do the demand of utilities building increasingly
Greatly.Existing building mostly is reinforced concrete structure, but traditional reinforced concrete structure is built
Process is complex, wastes substantial amounts of manpower and materials；Meanwhile, the building of reinforced concrete structure is torn open
Except time, need to carry out destructive dismounting, the construction material after dismounting cannot be carried out recycling, makes
The serious waste of the resource become.Therefore, the steel construction building body of plug-in type arises at the historic moment, and will add in advance
The body of wall that work is good is transported to precalculated position, and is connected with building body main frame, thus completes quickly and easily
Building body is built.Many sheet materials and body of wall are being transported to erecting bed after needing machine-shaping on a production line,
Needing to use substantial amounts of workbench in job shop, due to the restriction in place, many workbench need
Build, when building platform, the quality due to workbench is relatively big, and build process is relatively complicated temporarily,
Refer more particularly to the erection of workbench supporting leg, need to use specific purpose tool to complete, and need to make
Using substantial amounts of man power and material, the time of simultaneously building is longer, once safe thing easily occurs in misoperation
Therefore.
Therefore, the supporting leg elevating mechanism of a kind of workbench, to meeting the fast construction of workbench supporting leg,
Save man power and material simultaneously, reduce cost, the potential safety hazard occurred when being prevented effectively from building platform,
Just become the problem that those skilled in the art need solution badly.
Summary of the invention
It is an object of the invention to provide the supporting leg elevating mechanism of a kind of workbench, prop up to meeting workbench
The fast construction of lower limb, saves man power and material simultaneously, reduces cost, when being prevented effectively from building platform
The potential safety hazard occurred.
To achieve these goals, the present invention provides the elevating mechanism of a kind of workbench supporting leg, including level
The ratchet being rotatably arranged on workbench, the stop device of the ratchet clamping with described ratchet, even
Connecing the depression bar of described stop device, on described depression bar, slip cap is equipped with fixing seat, and described fixing seat is affixed
With workbench；On described ratchet, Eccentric-hinge is connected to the first stay bolt connecting rod and the second stay bolt connecting rod, and described
One stay bolt connecting rod and the pin joint of described ratchet and described second stay bolt connecting rod are hinged with described ratchet
Point line through the rotation center of circle of described ratchet, the hinged radius of described first stay bolt connecting rod and described the
The hinged radius of two stay bolt connecting rods is identical；The other end of described first stay bolt connecting rod is articulated with the first supporting leg,

Connecting for bolt, this kind of connected mode is relatively conventional, is simultaneously connected with intensity relatively big, and service life is longer,
It is the most convenient that later period maintenance is changed, and cost is relatively low.Above-mentioned connected mode can also select other even
Connect the higher mode of intensity as an alternative, such as welding etc..
It is further understood that, for welding between described depression bar 10 with described stop device 9.Above-mentioned company
The mode of connecing is chosen as welding, and this kind of connected mode is relatively conventional, is simultaneously connected with intensity relatively big, uses the longevity
Ordering longer, it is the most convenient that later period maintenance is changed, and greatly reduces cost.Connected mode herein also may be used
Think alternate manner, but bonding strength must be high, the most threaded etc..
In this mechanism, the material of described first spring 3 and the second spring 5 is carbon spring steel.Above-mentioned
At two, the selection of material is relatively conventional, is common used material, has on the one hand saved the manufacturing cost of mechanism,
On the other hand maintenance and the replacing in later stage are the most convenient, and cost is relatively low.Material at above-mentioned two selects
It is not limited solely to this, it is also possible to be adjusted on the premise of meeting Production requirement, such as, selects not
Rust steel matter is as the replacement scheme at above-mentioned two.
Specifically being understood by, the material of described return spring 12 is carbon spring steel.Above-mentioned position material
Selection relatively conventional, be common used material, on the one hand saved the manufacturing cost of mechanism, the opposing party
Maintenance and the replacing in face later stage are the most convenient, and cost is relatively low.Material at this selects not only to limit to
In this, it is also possible to be adjusted on the premise of meeting Production requirement, such as, stainless steel is selected to make
For the replacement scheme at this.
It is pointed out that ordinal numbers such as " first, second " described in literary composition is to distinguish same names not
Same structure, convenient only for describing, do not indicate that certain order, more should not be construed as any restriction.
By the way of explanation, only describe some one exemplary embodiment of the present invention above, undoubtedly,
For those of ordinary skill in the art, in the case of without departing from the spirit and scope of the present invention, Ke Yiyong
Described embodiment is modified by various different modes.Therefore, above-mentioned accompanying drawing and being described in substantially
It is illustrative, should not be construed as the restriction to the claims in the present invention protection domain.
