Abstract

The utility model discloses a lift type desk which comprises two desk legs and a desk face arranged above the desk legs. An adjustment rod is arranged on each desk leg in a sliding mode. The upper end of each adjustment rod is connected with a connecting base. The desk face is fixedly connected with the upper portion of the connecting base. A screw is arranged in each adjustment rod along the vertical direction. A driven cone gear is connected with the upper end of each screw. The lower end of each screw is connected with each leg in a screwing mode. A drive cone gear engaged with the driven cone gear is horizontally arranged on each driven cone gear. Each drive cone gear and each driven cone gear are located in the connecting base. The two drive cone gears are coaxially connected with each other through a transmission rod. A swing rod is connected with one end of the transmission rod. Due to the fact that two screws at two sides of a desk is driven by the transmission rod to rotate synchronically relative to the desk legs, so that adjustment of the height of the desk face is achieved. Due to the fact that the swing rod is connected with one end of the transmission rod, the transmission rod can be swung by hands and be driven to rotate, and therefore the lift type desk is convenient to use with no need for other auxiliary tools.

Description

Desk capable for rising and falling

Technical field

The utility model belongs to a tool technical field, is specifically related to a kind of Desk capable for rising and falling.

Background technology

The desk that the students in middle and primary schools of prior art use has and much all is designed to height-adjustable, can adapt to better like this height of adjusting easily desk after adolescent student height increases, the desk with adjustable height chair of prior art generally vertically arranges many group through holes on table leg, and be connected and fixed by bolt and nut assembly, its deficiency is also to need the instrument of spanner one class auxiliary when adjusting, and there is inconvenience in operation.

Summary of the invention

The purpose of this utility model is: the deficiency for prior art exists provides a kind of Stability Analysis of Structures, highly continuously adjustable Desk capable for rising and falling.

For realizing the purpose of the utility model, be achieved by the following technical solutions: a kind of Desk capable for rising and falling, the desktop that includes two table legs and be arranged at the table leg top, slidely connect adjusting rod on each described table leg, the adjusting rod upper end is connected with Connection Block, Connection Block top is fixedly connected with desktop, vertically be provided with screw rod in each adjusting rod, each screw rod upper end is connected with driven bevel gear, screw rod lower end and table leg are spirally connected, be horizontally disposed with the active conical gear with its engaged transmission on each driven bevel gear, initiatively conical gear and driven bevel gear are positioned at Connection Block, two initiatively conical gear is by the coaxial connection of drive link, and an end of drive link is connected with rocking bar.

As preferred version: described adjusting rod, drive link are connected with Connection Block by bearing respectively.

As preferred version: be connected with connecting rod between described two table legs.

As preferred version: described rocking bar end is hinged with handgrip.

As preferred version: be provided with storage chamber between two adjusting rods of described desktop below.

Compared with prior art, the beneficial effects of the utility model are: owing to by the two screw rods locking phase of a drive link driving desk both sides table leg is rotated, thereby realize the adjustment of height of table top, and drive link one end connects rocking bar, conveniently manually shaking drive link drives its rotation, very easy to use, need not to use other aid.

Embodiment

Shown in Figure 3 according to Fig. 1, the described a kind of Desk capable for rising and falling of present embodiment, the desktop 7 that includes two table legs 1 and be arranged at table leg 1 top, slidely connect adjusting rod 3 on each described table leg 1, adjusting rod 3 upper ends are connected with Connection Block 12, Connection Block 12 tops are fixedly connected with desktop 7, also be provided with the support arm that extends to desktop 7 front and back on the Connection Block 12, vertically be provided with screw rod 4 in each adjusting rod 3, each screw rod 4 upper end is connected with driven bevel gear 5, screw rod 4 lower ends and table leg 1 are spirally connected, table leg 1 interior relevant position is fixedly installed the nut that is spirally connected with table leg 1, be horizontally disposed with the active conical gear 6 with its engaged transmission on each driven bevel gear 5, initiatively roller gear 6 is mutually vertical with driven bevel gear 5, initiatively conical gear 6 and driven bevel gear 5 are positioned at 12, two actives of Connection Block conical gear 6 by drive link 9 coaxial connections, and an end of drive link 9 is connected with rocking bar 10.

Described adjusting rod 3, drive link 9 are connected with Connection Block 12 by bearing respectively, thereby realize level and smooth transmission and the axial location of adjusting rod 3, drive link 9.

Be connected with connecting rod 2 between described two table legs 1, connecting rod 2 horizontal directions take the shape of the letter U, and its two ends are connected in table leg 1 towards a side in desktop the place ahead, and student's lower limb when using desk just can not be subject to the stop limits of connecting rod 2 like this.

Described rocking bar 10 ends are hinged with handgrip 101, can regulate height of table top quickly and easily by handgrip 101.

Be provided with storage chamber 11 between two adjusting rods 3 of described desktop 1 below, storage chamber 11 openings make things convenient for the student to place books, stationery towards the rear of desk.

Also be provided with a recessed groove 8 on the described desktop 1, a groove is positioned at desktop 7 upper front part and distributes along the desktop length direction.

During use, drive drive link 9 rotations by shaking handgrip 101, the active conical gear 6 that is connected on the drive link drives driven bevel gear 5 rotations that are connected in screw rod 4 upper ends, thereby makes screw rod 4 relative table legs rotations that desktop 7 is descended or lifting.Desktop 7 is adjustable highly continuously like this, and the student is free-hand the adjustment at any time, and is very easy to use.
