Description
Technical field
The utility model relates to hand same table technical fields, specifically be a kind of based on the scalable of hand same table
Rocking handle.
Background technique
Same table is a kind of height-adjustable desk, and height can be adjusted according to the height of people, sitting posture and stance.Such as
The same table of the prior art generally comprises electric elevatable table and hand-operated lifting table, and especially its structure of hand-operated lifting table includes table
Plate, pedestal, Oscillating handle and liftable table leg connect the crossbeam of table leg, are equipped with screw-threaded shaft elevator structure, the silk in the table leg
Thick stick elevating mechanism includes the lead screw being rotatably connected in table leg inner tube, the coaxially connected drive gear set in one end of the lead screw
Part is threadedly coupled a pedestal on lead screw, and the pedestal is fixedly connected with the inner wall of inner tube；Transmission is equipped in the crossbeam
Bar, drive rod and Oscillating handle are sequentially connected, and for driving sliding tooth wheel to rotate, so that lead screw be made to rotate, the pedestal on lead screw is along silk
The length direction of thick stick is mobile, is subjected to displacement table leg outer tube relative to table leg inner tube, and lifting action, Suo Shu Oscillating handle occur for table leg
For driving drive rod rotation；The hand same table of the prior art is for the ease of user Yao Dong Oscillating handle Ji Shi Oscillating handle is not take up sky
Between；The Oscillating handle is traditionally arranged to be telescopic, namely Oscillating handle is pulled out on the outside of desktop by , in desktop lift adjustment height, this
The rotation of sample Ke Fang Bian Oscillating handle, when desktop is gone up and down to proper height, Oscillating handle is reduced in desktop by ,.You Yu Oscillating Bing Ji Oscillating handle driving
Axis is integral type, and the arm of force when rotation of Ci Oscillating handle is longer, and the stability of rotation is poor；In addition, the drive shaft of You Yu Oscillating handle with
The gearing relationships of drive rod, rocking handle could retract inside desktop after can only shaking some fixed angle, contract in this way in rocking handle
The desktop height adjusted must be changed when returning below desktop, made troubles to user's use.
Utility model content
The technical problems to be solved in the utility model is to overcome the defect of the above prior art, is provided a kind of in stretching table
Stability is high when plate shakes, and under any waving angle, can be retracted under desktop in the case where not changing desktop height
Telescoping cranking bar based on hand same table.
The technical solution of the utility model is to provide a kind of stretching based on hand same table having following structure
Contracting rocking handle: it includes the drive rod and rocking handle ontology with the transmission connection of same table elevating mechanism, during the rocking handle ontology includes
Empty connecting tube and the crank for being connected to connecting tube outer end, the connecting tube is slidably located on drive rod, and connecting tube can
Along circumferentially rotating for drive rod；The clamping machine for locking or unlocking connecting tube circumferentially is equipped between the connecting tube and drive rod
Structure, when connecting tube slides in and out along drive rod length direction to unfolded state, connecting tube is in the lock state, and connecting tube can band
Dynamic drive rod circumferentially rotates；When connecting tube is along drive rod length direction slid inward to contraction state, connecting tube is in unlock
State, connecting tube can be freely rotated around drive rod.
After using the above structure, a kind of telescoping cranking bar based on hand same table of the utility model and prior art phase
Than having the advantage that the telescoping cranking bar when in use, rocking handle ontology can be slided along drive rod, and connecting tube and drive rod
Between be equipped with lock or unlock connecting tube circumferentially clamping mechanism, the clamping mechanism connecting tube along drive rod length direction to
When sliding into unfolded state outside, connecting tube is in the lock state, and crank is arranged on the outside of desktop at this time, and shaking crank makes connecting tube
Drive rod is driven to circumferentially rotate, to realize the height adjustment of hand same table desktop；After desktop height adjustment, to table
Crank is pushed in plate, when making connecting tube along drive rod length direction slid inward to contraction state, connecting tube is in the unlocked state,
Connecting tube can be freely rotated around drive rod, can be retracted rocking handle ontology at this time or be hidden under desktop；Due to rocking handle ontology and drive
It is circumferentially to be locked by clamping mechanism between lever, for rocking handle ontology when shaking, the arm of force is shorter, and stability is high when shake；
In addition, only need to inwardly push away crank after desktop height adjustment, make connecting tube along drive rod length direction slid inward to receipts
When contracting state, connecting tube is in the unlocked state, at this time rotatable rocking handle ontology, is retracted to this physical efficiency of rocking handle smoothly under desktop,
And do not change desktop height.It is very easy to use.
Preferably, the lateral wall of the drive rod is circumferentially distributed along drive rod and long along drive rod equipped at least one section
The external tooth that direction extends is spent, the inner wall of the connection pipe orifice is equipped with internal tooth corresponding with external tooth, and the internal tooth exists
With the external tooth that can be caught in or be detached from connecting tube sliding process on drive rod.The connecting tube of Oscillating handle ontology is pulled outwardly along drive rod
When out, the internal tooth connected on pipe orifice inner wall is caught in the external tooth on drive rod, meshing state is between internal tooth and external tooth, therefore
Circumferentially rotating for connecting tube is limited, and when shaking crank, connecting tube drives drive rod to circumferentially rotate；When Tui Dong Oscillating handle sheet in Xiang
Body, when making to connect the internal tooth on pipe orifice inner wall and being detached from the external tooth on drive rod, connecting tube is in the unlocked state, and connecting tube can be around
Drive rod is freely rotated；The angle of crank conveniently adjusted in this way makes under crank retractable desktop, and under crank retraction desktop
In the process, drive rod does not rotate, and the height of desktop is constant, and operation is very easy.
Preferably, the external tooth is arranged on the outer end side wall of drive rod, the internal tooth is arranged outside connecting tube
On the inner sidewall for holding inner hole.In this way, external tooth and internal tooth are clamped, so not when Shi Oscillating handle ontology pulls out maximum distance
So that crank is stretched out desktop to the maximum extent and facilitate shake crank, and in crank to when being retracted under desktop, connecting tube is along driving
Lever slid inward relatively short distance can be such that external tooth and internal tooth is detached from, and the rotation of Fang Bian Oscillating handle ontology adjusts angle with to contracting under desktop
Into.
As an improvement, it further includes the bracket for being connected to same table the bottom of the table, the bracket is equipped with for rocking handle sheet
The mounting hole that body passes through, the connecting tube clearance fit is in mounting hole.The setting of the bracket make rocking handle ontology shake when more
Add stabilization, is not likely to produce shaking.
Preferably, the external tooth is set as outer small interior the first big circular conical surface close to one end of internal tooth.First circular cone
The setting in face enables internal tooth to be more convenient, more successfully be stuck on external tooth.
Preferably, it is in the second horn-like circular conical surface that it is small, which to be set as outer imperial palace, close to one end of external tooth for the internal tooth.It should
Internal tooth further enables internal tooth be more convenient, be more successfully stuck on external tooth close to the setting of second circular conical surface of one end of external tooth.
Preferably, connecting sleeve in the inner hole of the connecting tube outer end, the internal tooth is distributed in the center of casing
On the inner wall of hole.
