Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal touch display screens, in particular to a liquid crystal touch display screen which is easy to install. Background Art

[0002] The LCD touch screen is also called a touch panel. It is usually installed on a base bracket assembly or on a wall. When the graphic button on the screen is touched, the tactile feedback system on the screen can drive various connection devices according to a pre-programmed program. It can be used to replace the mechanical button panel. It has the characteristics of small size, low power consumption, and no radiation. It has now occupied a dominant position in the field of flat panel displays and is often used in conference rooms. It is usually used by meeting hosts to touch the screen with their fingers and display the content of the meeting.

[0003] When installing existing devices, the display screen is usually placed on the base bracket assembly and then connected through threads. Although the threaded fixation is relatively firm, the screws need to be fixed one by one, which is inconvenient during installation. In addition, most display screens are usually just turned off when not in use. Since there is no protection on the surface of the display screen, dust is easily accumulated, affecting its use.

The overall idea is as follows:

[0036] In view of the problems existing in the prior art, the utility model provides a liquid crystal touch display screen that is easy to install, including a base bracket assembly 11, a square plate 12 is fixedly installed on the surface of the base bracket assembly 11, a back cover 13 is fixedly installed on the side wall of the square plate 12, a first gear 14 is rotatably installed on the side wall of the square plate 12, a second gear 15 is rotatably installed on the side wall of the square plate 12, the first gear 14 is meshed with the second gear 15, a first rotating rod 16 is symmetrically rotatably installed on the side wall of the square plate 12, a third gear 17 is fixedly installed on the side wall of each group of first rotating rods 16, the second gear 15 is meshed with the third gear 17, and a synchronous belt 18 is rotatably installed between each group of first rotating rods 16;

[0037] The lower ends of the two synchronous belts 18 are fixedly mounted with sliding mechanisms;

[0038] The sliding mechanism includes a slide bar 19, and the square plate 12 is slidably installed with the slide bar 19. The upper ends of the two slide bars 19 are rotatably installed with a card plate 21. The upper ends of the two slide bars 19 are symmetrically fixed with a first spring 22, and each group of the first springs 22 is fixedly installed with the card plate 21. A support rod 23 is symmetrically fixedly installed on the side wall of the square plate 12. A fixed block 24 is arranged on the upper ends of the two support rods 23. A card slot 25 is symmetrically opened inside the fixed block 24. A straight groove 26 is symmetrically opened inside the fixed block 24. The two straight grooves 26 are respectively located above the card slot 25. A second spring 27 is symmetrically fixedly installed on the upper end of the fixed block 24. A connecting rod 28 is fixedly installed on the upper end of each group of the second springs 27. The fixed block 24 is symmetrically opened inside the fixed block 24. A placement groove 29 is provided, and the two placement grooves 29 are adapted to the support rod 23. By placing the display screen body 31 in the support rod 23 on the square plate 12, and rotating the first gear 14, and utilizing the transitional meshing of the second gear 15, the two slide bars 19 simultaneously slide toward the center of the square plate 12 while the synchronous belt 18 rotates until they fit into the card slot 25 in the fixed block 24, and finally utilizing the characteristics of the first spring 22 to make the card plate 21 snap into the card slot 25, the installation of the display screen body 31 can be completed, and only the connecting rod 28 needs to be pressed downward to squeeze the card plate 21, and the first gear 14 can be rotated again to complete the disassembly, so that the display screen body 31 can be installed or disassembled more conveniently;

[0039] A display screen body 31 is fixedly installed on the side wall of the fixing block 24, and a fixing piece 32 is symmetrically fixedly installed on the side wall of the display screen body 31. A coil spring 33 is rotatably installed between the two fixing pieces 32, and a slider 34 is symmetrically fixedly installed on the side wall of the coil spring 33. The slider 34 is slidably installed with the display screen body 31. A clamping hole 35 is opened on the surface of the display screen body 31, and a clamping column 36 is fixedly installed on the surface of the coil spring 33. The clamping column 36 is adapted to the clamping hole 35. The coil spring 33 is rotated on the fixing piece 32 by pulling the coil spring 33, and the coil spring 33 can be fixed by clamping the clamping column 36 with the clamping hole 35, so that the surface of the display screen body 31 can be protected from damage by dust and dirt, thereby improving the service life.

[0040] Working principle:

[0041] In the first step, when using, first align the placement groove 29 in the fixed block 24 on the display screen body 31 with the support rod 23 on the square plate 12 and insert it, then rotate the first gear 14 clockwise, at this time, the first gear 14 will mesh with the second gear 15, and at the same time, the second gear 15 will mesh with the third gear 17 close to the side of the second gear 15, and the two third gears 17 will rotate synchronously. Since the first rotating rod 16 and the synchronous belt 18 are rotatably installed, the third gear 17 will drive the synchronous belt 18 to rotate while rotating, and through the transitional engagement of the second gear 15, the two synchronous belts 18 rotate while the two sliding rods 19 slide to the center of the square plate 12 at the same time until they are fitted with the slot 25 in the fixed block 24. At this time, since the upper end of the first spring 22 is fixedly installed with the card plate 21, the card plate 21 will shrink downward. When entering the interior of the fixed block 24, since there is an inclined surface inside the fixed block 24, the first spring 22 will reset until the card plate 21 is connected to the card slot 25, thereby completing the fixation of the display screen body 31.

[0042] In the second step, when disassembly is required, the connecting rod 28 can be pressed down. Since the lower surface of the connecting rod 28 is in contact with the upper surface of the card plate 21 at this time, the connecting rod 28 will be driven downward by squeezing the connecting rod 28. At this time, the card plate 21 will shrink downward, and then the first gear 14 can be rotated to make the synchronous belt 18 drive the slide bar 19 to slide in the square plate 12 until it is out of the card slot 25. When the display screen body 31 is used after the end, the coil spring 33 can be slid on the display screen body 31 first. Since the coil spring 33 and the fixing part 32 are rotatably installed, the fixing part 32 will rotate at this time so that the coil spring 33 drives the slider 34 to be pulled out until it covers the surface of the display screen body 31. At this time, the card column 36 can be engaged with the card hole 35 to fix the coil spring 33, thereby completing the protection of the display screen body 31.

[0043] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
