Compared with the prior art, the computer lifting pedestal can be added to the existing office desk to achieve adjustment of the posture in work without replacing the desk or frequently setting or removing a computer desk, the display and the keyboard of the desktop computer are placed on the work table, the computer can be adjusted to achieve a proper sitting or standing posture in work, and the computer lifting pedestal is quite convenient to use.

Description

A kind of computer up-down pedestal that is used on the desk

Technical field

The present invention relates to office equipment, be specifically related to a kind of placement height that is used to regulate notebook computer or desktop computer display and keyboard, with the computer up-down pedestal of adjustment office posture.

Background technology

The personnel of office work, sitting is motionless before computer for a long time, will cause many harmful effects to healthy.If the office clan can adjust work posture, alternately adopt the office of sitting posture and standing posture, reduce the time of sitting, with the health that is very beneficial for self.The mode that realizes the standing posture office at present has two kinds basically: the one, but the desk of employing integral elevating; Reach the purpose of adjustment computer height through the height of regulating the whole office table, its shortcoming is to want to adopt when standing the mode of handling official business as the employee, must give up existing desk; Buy new liftable desk; The cost that drops into is higher, because the liftable desk is relatively heavier, wastes time and energy when regulating height in addition.The 2nd, through computer with foldable table of pad on existing desk; With the computer bed hedgehopping; Its shortcoming is: this mode relatively is fit to notebook computer, and not too is fit to desktop computer, and pad to go up or remove computer desk cumbersome; In addition, remove and to look for a place of placing it behind the computer desk in addition.

Summary of the invention

The object of the present invention is to provide a kind of placement height of regulating notebook computer or desktop computer display and keyboard that is specifically designed to,, alternately adopt the computer up-down pedestal of sitting posture and standing posture office with adjustment office posture.

The computer up-down pedestal that is used on the desk of the present invention, it is by base, support, working plate, elevating mechanism and locking mechanism are formed; Said base is placed on the desk; Said support is fixed on the base; Said working plate can move up and down along support under the effect of elevating mechanism; Said working plate can rest on arbitrary height and position on the support under the effect of locking mechanism.

Said support is an inverted U-shaped, and the arranged outside of its two U-shapeds leg has chute.

Said working plate is connected with two sliding sleeves, and said sliding sleeve is provided with two bearings that can in chute, move up and down, and said bearing plays the location and eliminates function of friction.

Said elevating mechanism is made up of handwheel, power transmission shaft, reel and steel wire rope; Said power transmission shaft is arranged on frame bottom; One end of said steel wire rope is fixed on the sliding sleeve, and the other end is fixed on the reel.

Said locking mechanism is arranged on the power transmission shaft, by the interior rotation set that is fixed on the power transmission shaft, and the rubbing hole that interior rotation set is peripheral, the torsionspring in being installed between rotation set and the rubbing hole, and reel is formed; The outer rim of said reel is provided with the boss that the groove that puts with inward turning is complementary.

The present invention compares with prior art; Need not change existing desk; Also need not on the desk of being everlasting, fill up or withdraw computer desk, only need additional up-down pedestal on existing desk, the display and the keyboard of notebook computer or desktop computer is placed on the working plate of up-down pedestal; Realize the up-down of working plate through shaking handwheel; The height of computer is adjusted to the position that is fit to standing posture or sitting posture office, thereby reaches adjustment office posture, alternately adopt the purpose of standing posture or sitting posture office.This product is very easy to use, helps promoting the work posture that the office clan adopts the standing posture office more, reduces office clan's motionless time of sitting, thereby improves office clan's health status.

The specific embodiment

Referring to Fig. 1, Fig. 2, shown in Figure 3, described computer up-down pedestal mainly is made up of base 6, housing 4, support 1, sliding sleeve 23, working plate 2, power transmission shaft 7, handwheel 5 and self-locking mechanism 25 etc.Wherein sliding sleeve 23 is connected with working plate 2, and sliding sleeve 23 is provided with 20, two bearings 20 of two bearings and can in chute 3, rolls up or down, moves up and down thereby drive working plate 2.

Referring to Fig. 3, Fig. 4, shown in Figure 6; The two ends of described power transmission shaft 7 respectively are provided with a self-locking mechanism 25; Said self-locking mechanism 25 is made up of interior rotation set 11, reel 8, torsionspring 9 and the rubbing hole 16 that is fixed on the housing 4, wherein in rotation set 11 pass through pin 19 in rotation set fixing hole 24 fixing with power transmission shaft 7.Torsionspring 9 is installed between interior rotation set 11 and the rubbing hole 16;

Torsionspring discount

14,15 is stuck in the inward turning grooving

side

12,13; There is a reel 8 inboard of interior rotation set 11; One end of steel wire rope 18 is fixed on the reel 8, and steel wire rope 18 is walked around lower pulley 17, upper sheave 21, and the other end is fixed on the sliding sleeve 23 through briquetting 22.On the outer rim of reel 8, be provided with a boss 10, boss 10 inserts inward turning grooving

sides

12,13 and torsionspring discount 14, between 15.

Referring to Fig. 3, Fig. 4, shown in, an end of described power transmission shaft 7 is provided with a handwheel 5, when shake handwheel 5 make in rotation set 11 when rotating by the A direction with power transmission shaft 7; Inward turning grooving side 13 drives torsionspring discount 14 and rotates to identical direction; Make discount 14 produce displacement, because the displacement of discount 14 is shunk torsionspring 9 and made its reduced diameter; Eliminated the frictional force between torsionspring 9 and the rubbing hole 16; Thereby rotation set 11 can freely rotate with power transmission shaft 7 in making, drives reel 8 and moves in a circle together, thereby steel wire rope 18 is wrapped on the reel 8; Steel wire rope 18 drives sliding sleeve 23 and bearing 20 moves up along chute 3, reaches the purpose that promotes working plate 2.

Referring to Fig. 3, shown in Figure 4; When shake handwheel 5 make in rotation set 11 when rotating by the opposite direction of A with power transmission shaft 7, inward turning grooving side 12 drives torsionspring discounts 15 and rotates to identical direction, makes torsionspring discount 15 produce displacements; Shrink torsionspring 9 and make its reduced diameter; Eliminated the frictional force between torsionspring 9 and the rubbing hole 16, thereby rotation set 11 can freely rotate in making with power transmission shaft 7, drive reel 8 and move in a circle together; Thereby steel wire rope 18 is decontroled from reel 8; Working plate 2 drives sliding sleeve 23 and bearing 20 and moves down along chute 3 under the effect of self gravitation and object to be carried body weight power, the final purpose that realizes reducing working plate 2.

When the needs lock-bit, the rotation that stops handwheel 5 can realize.Its course of work is following: because working plate 2 own wts and be placed on the effect of the weight of notebook computer or desktop computer display and keyboard on the working plate 2; Through steel wire rope 18 and reel 8; To the boss 10 that is connected as a single entity with reel 8 produce one with the rightabout active forces of A; Make the direction of torsionspring head 14 inside rotation set groove sides 13 produce displacement, push away the torque spring 9 that rises its external diameter is risen greatly, make that the frictional force between torsionspring 9 and the rubbing hole 16 increases; Rotation set 11 can't freely rotate with reel 8 in this moment, thereby can realize working plate 2 automatically locking in any position.
