Description
Technical field
The utility model relates to a kind of household goods, and more particularly, it relates to a kind of desk.
Background technology
Desk is as the thing generally used in people's life; demand is had in our every aspect of daily routines; such as have a meal; writing even can as a kind of ornament pendulum at home; general most of desks are all fixing, and this is that everybody is generally general, but sometimes in order to the demand of indivedual aspect; some desk can be designed to height adjustable, to adapt to the demand that some are becomed privileged.
And can the general desk that adjust height be all generally the height needing bimanualness to be used for regulating desk, to reach the comfortable of self operation, and the disadvantaged group such as handicapped or blind person just can not adjustment table height so freely for some both hands, others so just must be bothered to help, others help adjustment height user not necessarily can be allowed very comfortable, therefore can bring a lot of inconvenience to everybody.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of available both feet newly just can regulate the desk of height.
For achieving the above object, the utility model provides following technical scheme: a kind of desk, comprise desk body, described desk body comprises pedal, desktop, two supports, cavity is provided with in described support, rotating shaft is provided with between described support, the two ends of described rotating shaft penetrate support, and described rotating shaft two ends are equipped with gear, described gear is positioned at described cavity, described desktop is provided with a pin, described table pin inserts described cavity, described table pin is provided with the tooth bar be meshed with gear, described rotating shaft is provided with whirligig, transmission mechanism is provided with between described pedal and whirligig, described whirligig comprises stop mechanism, driving mechanism.
By adopting technique scheme, step on pedal and drive driving mechanism work by transmission mechanism, the rotation of the gear in rotating shaft and rotating shaft is driven by the rotational of driving mechanism, driving mechanism can make the piecemeal rotation of rotating shaft, and stop mechanism can block rotating shaft prevents it from circling round, because gear matches with the tooth bar on table pin, the rotation of gear drives the rising of table pin, and by stepping on pedal and just can control stop mechanism and driving mechanism making it depart from release rotating shaft, such desk can because the reason of self gravitation declines along with the rotation of gear, such user just can not be with the hands, be sitting on chair, only just can to desk furnishing height with both feet, and gears tooth pitch is less, accurate adjustment can be completed, the comfort of adjustment person can be met to the full extent.
The utility model is set to further: described whirligig also comprises shell, ratchet, described rotating shaft is through shell, described stop mechanism, described driving mechanism and described ratchet are positioned at described shell, described ratchet is fixed in rotating shaft, and described ratchet is arranged with rotating shaft is concentric, described driving mechanism comprises pull bar, described pull bar is L-type, described pull bar is provided with the first fixture block, described first fixture block side is hinged on pull bar, opposite side and ratchet clamping, torsion spring is provided with between described first fixture block and pull bar, described one end is fixed on bottom the first fixture block, the described torsion spring other end is fixed on described pull bar side, described pull bar one end passes shell, and pull bar is fixedly connected with described transmission mechanism.
The utility model is set to further: described stop mechanism comprises the second fixture block, connecting rod, described second fixture block side is fixed on connecting rod, the opposite side of described second fixture block and ratchet clamping, connecting rod is provided with the first elastic component, described first elastic component one end is fixed on the second fixture block, the other end of the first elastic component is fixed on shell, and described connecting rod is through the first elastic component, and described connecting rod one end passes shell is fixedly connected with transmission mechanism.
By adopting technique scheme, transmission mechanism drives pull bar, the first fixture block can be made to drive pawl wheel, the first fixture block hinged when reset can make the first fixture block reverse from ratchet by the extruding of torsion spring, thus original position can be blocked go back to, realize ratchet being driven smoothly to rotate, the movement transition of drive link vertical direction can be just rotary motion by such driving mechanism next time, due to the reason of gravity and table pin be connected with the gear in rotating shaft by tooth bar, the convolution of ratchet can be caused when the first fixture block rises and resets, and stop mechanism is stuck on ratchet by the second fixture block, prevent ratchet from circling round time ratchet is stopped the rotation, and the design of the first elastic component ensure that ratchet waits that fixture block can coincide when rotated be attached to ratchet surface, prevent ratchet from circling round at any time, and connecting rod be connected with transmission mechanism can when needs desk declines, smoothly the second fixture block is pulled away from ratchet, ratchet can be circled round and ensure that can being declined by desk smoothly of mechanism, this mechanism perfect.
The utility model is set to further: described transmission mechanism comprises the first drive link, the second drive link, and described pedal quantity is two, and a pedal is connected with described connecting rod by the first drive link, and another pedal is connected with described pull bar by the second drive link.
The utility model is set to further: described pedal comprises base plate and tramples block, describedly trample block side and base plate hinged, described trampling between block and base plate is provided with the second elastic component, and what described first drive link and the second drive link were hinged on two pedals respectively tramples block upper surface.
By adopting technique scheme, two pieces of pedals just in time meet the feature of human body two pin, so just, can put on a pedal by a pin, described block side and the base plate hinged trampled can enable pedal reasonably draw in open, and elastic component can make pedal can reset timely after trampling, facilitate durable, and drive link can be driven up and down by the reset of trampling block of pedal; When needing desk to rise, just step on the pedal be connected with driving mechanism again and again, drive the up and down of the second drive link and pull bar, thus drive the rotation of ratchet, so just, desk can be made slowly to increase, if when needing table height to decline, two pedals are needed all to step on, such stop mechanism and driving all separate with ratchet, because the gravity of desk, desk just can slowly decline, and unclamps two pedals and just desk can be fixed on this height when dropping to correct position, convenient practical again.
