Description
Technical field
The utility model relates to a kind of lifting pedestals, and in particular to a kind of lifting plug-in base.
Background technique
Generally all height is fixed for the pedestal of existing household ironing board, unadjustable, such as application No. is CN95208634.4
A kind of disclosed ironing board, single height is unadjustable, in order to meet the comfort of ironing operation, now needs a kind of height adjustable
The pedestal of section.
Utility model content
The purpose of this utility model is the lifting demand for existing ironing board, and a kind of descending operation provided facilitate it is fast
Prompt, compact-sized firm lifting plug-in base.
The purpose of this utility model can be realized by the following technical scheme:
A kind of lifting plug-in base, which is characterized in that including hollow column and lifting column, lifting column is plugged in column
Interior and opposite column can move up and down under the action of a lift drive mechanism, the lift drive mechanism include handle and perpendicular
To the drive rod being arranged in lifting column, the handle is rotatably arranged on the top of lifting column by a shaft, drive rod
Top eccentric rotary is arranged in shaft, and the lower part of drive rod is equipped with the inserted block crossed out, and above-mentioned column side offers more
A bayonet, multiple bayonets are alternatively arranged along the vertical direction, and the side of lifting column offers the first socket passed through for inserted block, inserted block
It can be inserted into any bayonet after first socket, drive rod movement can be made to drive by the rotation of above-mentioned handle drives shaft
Inserted block moves horizontally disengaging bayonet, and it further includes driving the mobile resetting-mechanism inserted to bayonet of inserted block that seat is driven in the lifting.External force behaviour
Make handle, drive rod can be made to move, so that inserted block movement be driven to be detached from bayonet, it is convenient to operate.
In a kind of above-mentioned lifting plug-in base, the resetting-mechanism is the torsional spring being arranged in shaft, torsion spring set
It is located in shaft and both ends difference elastic reaction is on lifting column and shaft.
In a kind of above-mentioned lifting plug-in base, the inserted block level is slidably arranged on above-mentioned lifting column, inserted block
On offer up and down run through inserted block loose slot, above-mentioned drive rod lower end pass through the loose slot, the lower part of drive rod is additionally provided with V-type
Slot, the direction of motion of the V-groove when the direction for projecting V-shaped and V-groove opening on vertical plane is inserted into above-mentioned bayonet with inserted block
On the contrary, loose slot is located in V-groove, a compressed spring, the elastic telescopic of compressed spring are also compressed between inserted block and lifting column
Direction is consistent with inserted block horizontal movement direction, and the cell wall of loose slot acts against V-groove cell wall always under the action of compressed spring
On, when not having external force, inserted block acts against the bottom of V-groove, and the center of rotation of the center of rotation and shaft of drive rod at this time
In same level, when the above-mentioned handle of external force rotates shaft, the drive rod horizontal movement direction with it is above-mentioned
Direction of motion when inserted block insertion bayonet is opposite.Due to drive rod eccentric setting, when the rotation of external force drive shaft, driving
Bar is the displacement for having horizontal direction, while having the displacement of vertical direction again, and no matter shaft rotates clockwise or turns counterclockwise
Dynamic, the horizontal movement direction of drive rod is with direction of motion when inserted block insertion bayonet on the contrary, so as to push inserted block to disengaging
The movement of bayonet direction；Simultaneously because the movement of drive rod vertical direction makes V-groove generate variation, same meeting with respect to inserted block upper and lower position
Inserted block is pushed to move to bayonet direction is detached from, so the horizontal movement of drive rod and vertical motion can all push inserted block level to transport
It is dynamic, the superposition of a displacement is formed, inserted block is accelerated to be detached from bayonet.
In a kind of above-mentioned lifting plug-in base, the lower part of the lifting column is equipped with a hollow limit sleeve, limit
Set peripheral shape is matched with lifting column internal via shape, limit sleeve and lifting column clearance fit, is installed with and is divided into limit sleeve
The upper cover and lower cover set form horizontal-extending limiting slot between upper cover and lower cover, and above-mentioned inserted block is slidably arranged in the limiting slot
Interior, the side of limit sleeve offers the second socket for passing through for inserted block and being connected to above-mentioned first jack, distinguishes in upper cover, lower lid
The upper opening for supplying above-mentioned drive rod to wear, under shed are offered, the lower end of drive rod sequentially passes through upper opening, activity from top to bottom
Slot, under shed.Inserted block is inserted into bayonet after sequentially passing through the second socket, the first socket from inside to outside, and limit sleeve is inserted by inserted block
Second socket and lifting column form fixation, and since inserted block needs move horizontally, have one between inserted block and the second socket
Fixed upper and lower gap, which makes limit sleeve have certain up and down amount, so that it is stuck to can effectively prevent inserted block.
In a kind of above-mentioned lifting plug-in base, the lift drive mechanism further includes being arranged at above-mentioned drive rod bottom
The constant force spring in portion, constant force spring are in " b " font, and constant force spring inner ring is arranged on above-mentioned limit sleeve by a fixing axle, permanent
On the fixed above-mentioned lifting column in the extension end of power spring, constant force spring makes drive rod by downward pulling force by limit sleeve.Constant force
Spring is used for balance drive bar stress, the state for cooperating torsional spring that drive rod is made to be in both ends tension.
In a kind of above-mentioned lifting plug-in base, the limit sleeve bottom is equipped with position-limited edge, and position-limited edge is to lifting column
Bottom circumferentially extending.
Compared with prior art, the utility model pull-up or push handle can make inserted block be detached from bayonet, therefore when need on
Handle is pulled up when rising, and when that need to decline, pushes handle, it is convenient to operate；When drive rod is with shaft eccentric rotary, driving
The movement in the horizontal and vertical direction of bar can be such that inserted block moves to the direction for being detached from bayonet, and formation is displacement superposed, enable inserted block
It is rapidly separated bayonet.
