Embodiment 1

[0023] Such as figure 1 and figure 2 As shown, the present invention includes a base 1, the base 1 is connected with a fixed rod 2, the fixed rod 2 is sleeved with a sleeve 3, and the fixed rod 2 is provided with a push-pull mechanism 4 for driving the sleeve 3 to move; The other end is connected with rotating seat 31 by thrust bearing, and the other end of rotating seat 31 is fixed with display screen main body 5, is fixed with rotating chute 32 on the sleeve 3, is provided with rotating rack 33 in rotating chute 32 inner sleeves, and rotates Seat 31 is fixed with rotating ring gear 34, and rotating rack 33 is meshed with rotating ring gear 34, and is engaged with the rotating wedge block 35 that prevents rotating rack 33 from moving voluntarily between rotating rack 33 and rotating chute 32.

[0024] The base 1 of the present invention is connected with a fixed rod 2. When the push-pull mechanism 4 on the fixed rod 2 is driven, the push-pull mechanism 4 can push up or pull...

Embodiment 2

[0026] On the basis of Embodiment 1, the push-pull mechanism 4 includes a push-pull rod 41, one end of the push-pull rod 41 is hinged with the sleeve 3, and the other end of the push-pull rod 41 is hinged with a rotating ring 42, and the rotating ring 42 is connected to the fixed rod through a bearing 2, the base 1 is equipped with an engagement mechanism 6 for changing the direction of the rotating ring 42; a limit bar is arranged on the fixed rod 2, and a limit groove is arranged on the inner wall of the sleeve 3, and the limit bar is sleeved in the limit groove.

[0027] After turning the rotating circle 42 to a certain position, fix its position with the engagement mechanism 6, then the direction in which the push-pull rod 41 tilts is determined, and the projected length of the push-pull rod 41 in the vertical direction is determined, and the sleeve 3 and the display screen main body 5 The lifting height is determined. Therefore, it is only necessary to adjust the rotating...

Embodiment 3

[0029] On the basis of Embodiment 1 or Embodiment 2, the engaging mechanism 6 includes a chute 61 , a rack 62 is sleeved in the chute 61 , and a ring gear is arranged on the rotating ring 42 , and the ring gear meshes with the rack 62 .

[0030] When the rack 62 is pulled, the rack 62 slides in the chute 61 , the rack 62 meshes with the ring gear, and the rack 62 pulls the rotating ring 42 to rotate accordingly. Therefore, only the rack 62 needs to be pulled, and the turning direction of the rotating ring 42 can be precisely adjusted, and the height of the display screen main body 5 can be precisely adjusted, which improves the convenience of operation.

Abstract

The invention relates to the field of liquid crystal displays, in particular to a height and steering accurately-adjustable display. According to the technical scheme, the height and steering accurately-adjustable display is characterized in that the height and steering accurately-adjustable display comprises a base; the base is connected with a fixing rod; the fixing rod is sleeved with a sleeve;a push-and-pull mechanism for driving the sleeve to move is arranged on the fixing rod; the other end of the sleeve is connected with a rotary seat through a thrust bearing; a display screen main body is fixedly arranged at the other end of the rotary seat; a rotary sliding groove is fixed to the sleeve; a rotary rack is sleeved with the rotary sliding groove; a rotary gear ring is fixed to the rotary seat; the rotary rack is engaged with the rotary gear ring; and a rotary wedge-shaped block capable of preventing the rotary rack from moving automatically is clamped between the rotary rack andthe rotary sliding groove. With the adoption of the height and steering accurately-adjustable display, the problem that the height and the steering of an existing liquid crystal display cannot be adjusted accurately and easily is solved.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a display whose height and direction can be adjusted precisely. Background technique [0002] Liquid crystal display is a flat and ultra-thin display device, which consists of a certain number of color or black and white pixels, placed in front of the light source or reflective surface. Liquid crystal displays consume very little power, making them favored by engineers for electronic devices that run on batteries. Its main principle is to stimulate liquid crystal molecules with current to generate points, lines, and surfaces to form a picture with the back lamp tube. [0003] The working principle of liquid crystal display: Liquid crystal is a special substance between solid and liquid. It is an organic compound, which is liquid under normal conditions, but its molecular arrangement is as regular as solid crystal, so it is named liquid crystal. , Its other special propert...
