Embodiment 1
[0036] like Figure 1-4 As shown, the horizontal and vertical screen switching structure includes a rotating part 1 installed on the back cover of the liquid crystal touch all-in-one machine 2, a connecting part 4 inserted into the rotating part 1 and rotatably connected to the rotating part 1, and the connecting part 4 The bracket 3 that is fixedly connected, and the bracket 3 can be hung on a wall, or a frame, or a position that can be hung on a cabinet wall or the like.
[0037] Specifically, the bracket 3 is provided with two hooks 33 for hanging.
[0038] Wherein, the two ends of the rotating member 1 are provided with protruding rings 11 extending outward, the end of one of the protruding rings 11 is in conflict with the bracket 3, and the other protruding ring is inserted into the liquid crystal touch all-in-one machine 2 , the rotating member 1 interferes with the back cover of the liquid crystal touch all-in-one machine 2, and is screwed and fixed with the back cover...
Embodiment 2
[0060] like Figure 4 As shown, a liquid crystal touch all-in-one machine using the horizontal and vertical screen switching structure of Embodiment 1 includes a plurality of card holes 21 and connection holes 22 provided on the back cover.
[0061] Wherein, the elastic protrusion 51 is engaged in the locking hole 21 in an elastically shrinkable manner.
[0062] Wherein, the connecting piece 4 passes through the connecting hole 22 , is inserted into the installation hole 12 from the liquid crystal touch all-in-one machine 2 , and is screwed and fixed with the bracket 3 .
[0063] Wherein, the rear cover of the liquid crystal touch all-in-one machine 2 is provided with a plurality of second screw holes 23 matched with the first through holes 13, and the first through holes 13 and the second screw holes 23 are passed through by means of screws or screws. The two screw holes 23 are screwed and connected to fix the rotating member 1 on the back cover.
[0064] Wherein, the insid...

Abstract
The invention discloses a horizontal and vertical screen switching structure. The horizontal and vertical screen switching structure comprises a rotating part, a support, a connector, a limiting part and a rotation detection mechanism, wherein the rotating part is fixedly connected with a rear cover of a liquid crystal touch all-in-one machine; the support is rotatably connected with the rotating part; the connector is inserted into the rotating part and is fixedly connected with the support; the limiting part is arranged on the support, and an elastic bump is arranged at the end part of the limiting part; the rotation detection mechanism is electrically connected with a control circuit board in the liquid crystal touch all-in-one machine; when the rotating part rotates, the control circuit board monitors a rotating angle signal of the rotating part in real time through the rotation detection mechanism; when the rotating angle of the rotating part is +/-90 degrees, the liquid crystal touch all-in-one machine is switched into a horizontal screen display mode; and when the rotating angle of the rotating part is 0 degree or 180 degrees, the liquid crystal touch all-in-one machine is switched into a vertical screen display mode. The invention further discloses the liquid crystal touch all-in-one machine applying the horizontal and vertical screen switching structure. The problems that an existing liquid crystal touch all-in-one machine cannot rotate to switch the horizontal direction and the vertical direction, so that display modes cannot be switched according to multiple functions integrated on the all-in-one machine, and the liquid crystal touch all-in-one machine is inconvenient for a user to use are solved.
Description
technical field [0001] The invention relates to the technical field of multimedia equipment, in particular to a horizontal and vertical screen switching structure and a liquid crystal touch all-in-one machine using the structure. Background technique [0002] The LCD touch all-in-one machine has brought a lot of convenience to people's life and work. With the development of the LCD touch all-in-one machine technology, the functions that the LCD touch all-in-one machine can realize also increase. Multimedia devices with a single function can no longer meet the needs of consumers. LCD touch all-in-one computers with multiple functions have gradually replaced traditional multimedia devices and entered people's daily life. [0003] When the existing liquid crystal touch all-in-one machine realizes a variety of different functions, the connection between the screen and the bracket is fixed. Application, to switch the display mode of the display screen, but because the display sc...
