Abstract

The utility model relates to a desktop computer display screen lift stand, and overcomes the defect that existing lift type computer desks are complicated to operate. The desktop computer display screen lift stand comprises a support platform and a lift platform. The support platform comprises a base plate and an adjusting seat. A plurality of annular sliding grooves are horizontally formed along the circumference of the inner wall of the adjusting seat, and three vertical sliding grooves are axially formed in the inner wall of the adjusting seat. The lift platform comprises a placing plate and a movable seat, three protrusions are fixedly arranged along the same circumference of the outer wall of the movable seat, and the shapes of the protrusions correspond to the shapes of the annular sliding grooves and the vertical sliding grooves. The outer diameter of the movable seat is a bit smaller than the inner diameter of the adjusting seat, the movable seat on the lift stand is inserted into the adjusting seat on the support platform, and the protrusions are located in the same annular sliding grooves. By the arrangement that the lift stand can be arranged in the annular sliding grooves different in height to adjust the height of a desktop computer screen, so that sight angles can be changed to allow the neck vertebra of a user to exercise sufficiently, and cervical spondylosis can be effectively prevented. The desktop computer display screen lift stand is simple in structure, low in manufacturing, good in stability and convenient and rapid to operate.

Description

A kind of desktop computer display screen lifting frame

Technical field

The utility model belongs to the office appliance field, is specifically related to a kind of desktop computer display screen lifting frame.

Background technique

Along with the continuous development of science and technology, computer is as the carrier of information transmission and reception, is dissolved into closely in our work, studying and living.Desktop computer is because of its superior performance, and is stable and be widely adopted.Yet, constantly increase because of long-term disease of cervical vetebra and the eyesight decline crowd who causes in the face of computer every year, trace it to its cause is that the computer display screen putting position is fixed, and it is excessive with the sight line drop, user's cervical vertebra is the binocular of big camber line and looks up or overlook posture, and keep a posture for a long time, can not get activity.At present, the existing dual-purpose lift type computer table that allows people's sitting or stand to use computer can realized causes manufacture cost too high but its structure is comparatively complicated, and adopts pneumatic usually or the hydraulic lifting mode, thereby cause the desktop poor stability, descending operation complexity, time-consuming.

Summary of the invention

The utility model provides a kind of desktop computer display screen lifting frame at the deficiencies in the prior art.

The utility model comprises support platform and raising platform.

Described support platform comprises base plate and adjustment seat; Base plate is dull and stereotyped, and adjustment seat is columnar structured, and adjustment seat vertically is fixedly installed on the central position of plate upper surface.The inwall of adjustment seat has a plurality of annular grooves, has three vertical chutes vertically along the circumference level, and a plurality of annular grooves are equally spaced vertically, and three vertical chutes along the circumferential direction are equally spaced; Each vertical chute runs through a plurality of annular grooves, and is opened on the last end face of adjustment seat sidewall.

Described raising platform comprises placing plate and active base; Placing plate is circular dull and stereotyped, and active base is cylindrical body, and active base vertically is fixedly installed on the central position of placing plate lower surface.The outer wall of active base is set with three projectioies along same circumference, and three projectioies along the circumferential direction are equally spaced, and the shape of projection is corresponding with the shape of annular groove and vertical chute.

The external diameter of active base is slightly less than the internal diameter of adjustment seat, and the active base of raising platform is inserted in the adjustment seat of support platform, and three projectioies are positioned at same annular groove.

The utility model is regulated desktop computer display screen height by raising platform is arranged in the annular groove of different heights, thereby changes sight angle, makes cervical vertebra obtain abundant activity, effectively pre-preventing cervical spondylosis.The utility model is simple in structure, low cost of manufacture, and good stability, it is very convenient to operate.

Description of drawings

Fig. 1 is overall structure schematic representation of the present utility model;

Fig. 2 is the structural representation of supporting base among Fig. 1;

Fig. 3 is the structural representation of raising platform among Fig. 1.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1, a kind of desktop computer display screen lifting frame comprises support platform 1 and raising platform 2.

As shown in Figure 2, support platform 1 comprises base plate 1-1 and adjustment seat 1-2; Base plate 1-1 is dull and stereotyped, and adjustment seat 1-2 is columnar structured, and adjustment seat 1-2 vertically is fixedly installed on the central position of base plate 1-1 upper surface.The inwall of adjustment seat 1-2 has a plurality of annular groove 1-3, has three vertical chute 1-4 vertically along the circumference level, and a plurality of annular groove 1-3 are equally spaced vertically, and three vertical chute 1-4 along the circumferential direction are equally spaced; Each vertical chute 1-4 runs through a plurality of annular groove 1-3, and is opened on the last end face of adjustment seat 1-2 sidewall.

As shown in Figure 3, raising platform 2 comprises placing plate 2-1 and active base 2-2; Placing plate 2-1 is circular dull and stereotyped, and active base 2-2 is cylindrical body, and active base 2-2 vertically is fixedly installed on the central position of placing plate 2-1 lower surface.The outer wall of active base 2-2 is set with three protruding 2-3 along same circumference, and three protruding 2-3 along the circumferential direction are equally spaced, and the shape of projection is corresponding with the shape of annular groove 1-3 and vertical chute 1-4.

The external diameter of active base 2-2 is slightly less than the internal diameter of adjustment seat 1-2, and the active base 2-2 of raising platform 2 inserts in the adjustment seat 1-2 of support platform 1, and three protruding 2-3 are positioned at same annular groove 1-3.

During use, computer monitor places on the placing plate 2-1, when needing to regulate the display screen height, rotation and lifting platform 2 makes three protruding 2-3 arrive the position of three vertical chute 1-4 respectively, then raising platform 2 is raise or is reduced to and need the position, rotation and lifting platform 2 makes three protruding 2-3 mobile in same annular groove 1-3 again, raising platform 2 can be supported.

This lifting frame can conveniently be regulated the height of raising platform 2, adopts three convex design, supports more stable.Simultaneously, rotate the display screen angle as need, only need rotation and lifting platform 2 to get final product.
