Abstract

The utility model relates to a screw adjustable lift type working table which comprises a working disc 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; the inner hole of the inner pipe is in interference fit with the screw seat; the screw is screwed in the screw seat in a threaded manner; the outer pipe component comprises an active bevel gear, a driven bevel gear and an outer pipe; the top of the outer pipe supports and is connected with the working disc component; the inner pipe is movably sleeved with the outer pipe; the handle component penetrates through the outer pipe and is connected with the active bevel gear in the outer pipe in a transmission manner; the drive bevel gear is meshed with the driven bevel gear in the outer pipe; and the driven bevel gear is connected onto the screw. The screw is rotated through the matching of bevel gears, the screw limited by a bearing pedestal cooperates with the action of transmission threads of the screw seat to go up and down, the outer pipe is driven to go up and down along the inner pipe, and a tool disc component on the outer pipe can go up and down as long as the handle component is rocked.

Description

Screw rod is regulated lifting type workbench

Technical field

The utility model 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 is mainly the lifting that the holder of armrest handle carrys out adjusting operating platform, on workbench, is placed with while bearing a heavy burden, and self-powered platform need first be taken down heavy burden, then goes lifting, very inconvenient, or directly lifting, but sweat very; 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 coordinate, and makes pallet occur rotating, and easily topples.

Summary of the invention

The shortcoming existed in order to overcome prior art, the purpose of this utility model is to provide a kind of screw rod easy to use, laborsaving, safe when being loaded with heavy burden to regulate lifting type workbench.

Technical solution of the present utility model is: a kind of screw rod is regulated lifting type workbench, comprise scratch diskette assembly, Handleset, outer tube assembly, inner tube assembly and work chassis, it is characterized in that: described inner tube assembly comprises screw bolt seat, screw rod and inner tube, the inner tube bottom connects the work chassis, the endoporus of inner tube and screw bolt seat interference fit, screw flight is rotatably connected in 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 inner tube, Handleset is connected to the outer tube upper driving and connects the drive bevel gear in outer tube, driven wheel of differential engagement in drive bevel gear and outer tube, driven wheel of differential is connected on screw rod.

Further, the top of described screw rod is fixedly connected with driven wheel of differential through back-up ring with screw, driven wheel of differential is supported on the bearing block upper surface be fixedly connected with within the outer tube through taper roll bearing, between bearing block lower surface and screw rod, be connected through bearing and the shaft shoulder are spacing, 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 utility model reaches is: (1) adopts bevel gear to coordinate and makes the screw rod rotation, screw rod is subject to the effect of the spacing cooperation screw bolt seat of bearing block motion thread, screw rod is oscilaltion in screw bolt seat, drive respectively outer tube along the upper and lower lifting of inner tube by screw rod by the shaft shoulder and bearing block, the swinging handle assembly can be regulated tool shelf assembly lifting on 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) adopt the design of driving and driven bevel gear, changed the Handleset direction of rotation, thereby Handleset is fixed on outer tube one side, facilitates user's swinging handle.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

The partial enlarged view that Fig. 2 is Fig. 1.

In figure: Handleset 1, drive bevel gear 2, sell 3, taper roll bearing 4, bearing 5, outer tube assembly 6, inner tube assembly 7, outer tube 8, screw rod 9, inner tube 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 utility model is further described.

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

When this device is used: the swinging handle assembly, 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, in the interior rotation of screw bolt seat 16, drives outer tube 8 lifting on inner tube 10 through the shaft shoulder 15 and bearing block 14 respectively, thereby drive, is supported on the tool shelf assembly lifting on outer tube 8.
