Abstract

The invention relates to a screw-adjustment lifting type workbench which comprises a working disk component, a handle component, an outer pipe component, an inner pipe component and a working base plate, wherein the inner pipe component comprises a screw seat, a screw and an inner pipe; the bottom of the inner pipe is connected with the working base plate; an inner hole of the inner pipe is in interference fit with the screw seat; the screw is threaded in the screw seat; the outer pipe component comprises a driving bevel gear, a driven bevel gear and an outer pipe; the top of the outer pipe is in supporting connection with the working disk component; the outer pipe is movably sleeved on the inner pipe; the handle component is inserted into the driving bevel gear, which is connected into the outer pipe, on the outer pipe; the driving bevel gear is meshed with the driven bevel gear in the outer pipe; and the driven bevel gear is connected to the screw. The bevel gears are matched with each other, so that the screw rotates; under limitation of a bearing pedestal and action of the transmission thread of the screw seat, the screw can go up and down in the screw seat to drive the outer pipe to go up and down along the inner pipe; and the handle component is rocked to adjust lifting of the working disk component on the outer pipe.

Description

Screw rod is regulated the lift workbench

Technical field

The present invention relates to a kind of self-powered platform, is the workbench that a kind of hand-rail type screw rod is regulated lifting specifically.

Background technology

The work on hand platform mainly is the lifting that workbench is regulated in the holder of armrest handle, and when being placed with heavy burden on the workbench, self-powered platform need be taken down heavy burden earlier, and capable lifting is very inconvenient again, perhaps directly lifting, the gas of but requiring great effort very much; Keep certain interval between the inside and outside pipe of workbench, easily block during lifting, make the lifting inconvenience; The workbench inner and outer pipe adopts pipe to cooperate, and makes pallet occur rotating, and easily topples.

Summary of the invention

In order to overcome the shortcoming that prior art exists, the object of the present invention is to provide a kind of screw rod easy to use, laborsaving, safe when being loaded with heavy burden to regulate the lift workbench.

Technical solution of the present invention is: a kind of screw rod is regulated the lift workbench, comprise scratch diskette assembly, Handleset, outer tube assembly, interior pipe assembly and work chassis, it is characterized in that: the pipe assembly comprises screw bolt seat, screw rod and interior pipe in described, interior pipe bottom connects the work chassis, the endoporus of interior pipe and screw bolt seat interference fit, screw flight is rotatably connected in the screw bolt seat; Described outer tube assembly comprises drive bevel gear, driven wheel of differential and outer tube, the outer tube top-supported connects the scratch diskette assembly, the outer tube pivot bush unit is outside interior pipe, Handleset is connected to the drive bevel gear in the outer tube that is in transmission connection on the outer tube, driven wheel of differential engagement in drive bevel gear and the outer tube, driven wheel of differential is connected on the screw rod.

Further, driven wheel of differential is fixedlyed connected through back-up ring in the top of described screw rod with screw, driven wheel of differential is supported on the bearing block upper surface that is fixedly connected in the outer tube through taper roll bearing, is connected through bearing and the shaft shoulder are spacing between bearing block lower surface and the screw rod, and is described.

Further, described screw rod bottom is provided with spring catch.

Again further, described inner and outer pipe is square tube.

?

After adopting above technical scheme, the beneficial effect that the present invention reaches is: (1) is adopted bevel gear to cooperate and is made the screw rod rotation, screw rod is subjected to the effect of the spacing cooperation screw bolt seat of bearing block motion thread, screw rod is oscilaltion in screw bolt seat, drive outer tube respectively along the upper and lower lifting of interior pipe by screw rod by the shaft shoulder and bearing block, shake Handleset and can regulate tool shelf assembly lifting on the outer tube; (2) inner and outer pipe all adopts square tube, and fit clearance can be to optimum state, and pallet can not rotate, and is difficult for deflection, can not topple, and guarantees safety; (3) design of the driving and driven bevel gear of employing changed the Handleset direction of rotation, thereby Handleset is fixed on outer tube one side, makes things convenient for the user to shake handle.

Description of drawings

Fig. 1 is structural representation of the present invention.

Fig. 2 is the partial enlarged view of Fig. 1.

Among the figure: Handleset 1, drive bevel gear 2, pin 3, taper roll bearing 4, bearing 5, outer tube assembly 6, interior pipe assembly 7, outer tube 8, screw rod 9, interior pipe 10, screw 11, back-up ring 12, driven wheel of differential 13, bearing block 14, the shaft shoulder 15, screw bolt seat 16, tool shelf assembly 17, spring catch 18, work chassis 19.

The specific embodiment

Below in conjunction with drawings and Examples the present invention is further described.

Shown in Fig. 1,2, a kind of screw rod is regulated the lift workbench and is comprised scratch diskette assembly 17, Handleset 1, outer tube assembly 6, interior pipe assembly 7 and work chassis 19.Interior pipe assembly 7 comprises screw bolt seat 16, screw rod 9 and interior pipe 10, and interior pipe 10 bottoms connect work chassis 19, interior pipe 10 top endoporus and screw bolt seat 16 interference fit, and screw rod 9 screw threads are rotatably connected in the screw bolt seat 16; Outer tube assembly 6 comprises drive bevel gear 2, driven wheel of differential 13 and outer tube 8, outer tube 8 top-supported connect scratch diskette assembly 17, outer tube 8 pivot bush units are outside interior pipe 10, Handleset 1 is connected to the drive bevel gear 2 of selling on the outer tube 8 in the 3 fixed conveyor connection outer tube 8, driven wheel of differential 13 engagements in drive bevel gear 2 and the outer tube 8, driven wheel of differential 13 is fixedly connected on the screw rod 9 through back-up ring 12 and screw 11, driven wheel of differential 13 is supported on bearing block 14 upper surfaces that are fixedly connected in the outer tube 8 through taper roll bearing 4, through bearing 5 and 15 spacing connections of the shaft shoulder, screw rod 9 bottoms are provided with and the spacing spring catch that cooperates 18 of interior pipe 10 inwalls between bearing block 14 lower surfaces and the screw rod 9; Inner and outer pipe is square tube.

When this device uses: shake Handleset, drive bevel gear 2 is rotated with the handle assembly, driven wheel of differential 13 rotates through drive bevel gear 2 engagements, driven wheel of differential 13 drives screw rod 9 and rotates, screw rod 9 upper and lower spacing through bearing block 14 and the shaft shoulder 15 respectively, screw rod 9 rotates in screw bolt seat 16, drives outer tube 8 lifting on interior pipe 10 through the shaft shoulder 15 and bearing block 14 respectively, thereby drives the tool shelf assembly lifting that is supported on the outer tube 8.
