A seamless splicing display screen

Abstract

The present invention discloses a seamlessly spliced ​​display screen, comprising a snap-fitting body, wherein the snap-fitting body comprises a snap-fitting block, a slider, a spring, an inner cavity and a rotating arm. The device is provided with a snap-fitting connection between the snap-fitting block and the slot, thereby easily splicing a first display screen and a second display screen. The turntable can be controlled to rotate by turning a knob, and then the turntable is controlled to make the passing surface and the positioning slot close to each other, thereby allowing the rotating arm to rotate, so that the snap-fitting block is rotated away from the inside of the slot, thereby separating the two display screens. The operation is simple, and the work efficiency of the installation is improved. At the same time, a transparent sticker is provided and placed in the gap between the two display screens to prevent dust from entering, thereby avoiding the risk of damage to internal components of the device due to dust entering. At the same time, the transparent strip can allow light from the display screen to enter the transparent strip for light guidance, thereby reducing the influence of the gap on the display effect.

A through surface 27 is provided on one side of the turntable 18, and a positioning surface 28 is provided on the other side of the turntable 18. When the through surface 27 is rotated to the side of the positioning groove 26, the rotating arm 13 can be rotated. When the positioning surface 28 is rotated to the side of the positioning groove 26, the positioning groove 26 and the positioning surface 28 are engaged, so that the rotating arm 13 can no longer rotate. The bottom of the turntable 18 is fixedly connected to the connecting shaft 20, and the bottom end of the connecting shaft 20 is fixedly connected to the knob 21. The card block 8 can be lifted and lowered in the inner cavity 12 through the slider 10. When the convex plate 5 passes by on one side of the inclined surface of the card block 8, the card block 8 moves downward through the action of the inclined surface. When the cam 5 passes through the card block 8, the spring 11 is pressed by the slider 10, so that the cam 5 bounces up, so that the card block 8 and the slot 7 on the surface of the cam 5 are engaged with each other, thereby achieving the purpose of fixing the cam 5. When it is necessary to separate it, it is only necessary to rotate the knob 21, and the knob 21 drives the turntable 18 to rotate through the connecting shaft 20, thereby separating the positioning surface 28 from the positioning groove 26, and rotating the passing surface 27 to the side of the positioning groove 26, so that the turntable 18 is not engaged with the positioning groove 26, so that the rotating arm 13 can rotate, thereby making the card block 8 away from the slot 7, so that the cam 5 can be easily taken out.

[0028] One end of the convex plate 5 is fixedly connected to a connecting plate 6, and the top of the connecting plate 6 is fixedly connected to the second display screen 2. A splint 17 is provided between the first display screen 1 and the second display screen 2. The top of the splint 17 is fixedly connected to a transparent sticker 16, and the bottom of the transparent sticker 16 is respectively adhered to the first display screen 1 and the second display screen 2. The additional transparent sticker 16 can cover the gap between the interconnected display screens, so that dust will not easily fall into the gap, thereby protecting the normal operation of the components inside the device. A fixing hole 15 is provided on the surface of the splint 17, and a positioning rod 29 is provided on one side of the convex plate 5. The positions of the positioning rod 29 and the socket 22 correspond to each other. When the convex plate 5 is inserted into the interior of the plug-in plate 3, the positioning rod 29 will be correspondingly inserted into the interior of the socket 22, so that the connecting plate 6 and the plug-in plate 3 can be better connected.

[0029] The working principle of the present invention is:

[0030] When the device needs to be installed, the convex plate 5 is aligned with the inside of the fixing groove 23, and the positioning rod 29 is inserted along the fixing hole 15 and the insertion hole 22. The inclined surface of the card block 8 passes through the convex plate 5 to press the card block 8 downward, and then the slider 10 squeezes the spring 11, so that after the convex plate 5 passes the card block 8, the spring 11 applies force to bounce the card block 8 upward, so that the card block 8 and the slot 7 on the surface of the convex plate 5 are engaged with each other, thereby achieving the purpose of fixing the convex plate 5. When it is necessary to separate it, it is only necessary to rotate the knob 21, and the knob 21 drives the turntable 18 to rotate through the connecting shaft 20, thereby aligning the positioning surface 28 with the positioning groove 26. Separate them, rotate the through surface 27 to the side of the positioning groove 26, so that the turntable 18 is not engaged with the positioning groove 26, and then the rotating arm 13 can be rotated, so that the block 8 is away from the slot 7, so that the convex plate 5 can be easily taken out, and at the same time, there is a clamping plate 17 between the plug-in plate 3 and the connecting plate 6, and the transparent sticker 16 on the top of the clamping plate 17 can prevent dust from entering the gap and avoid damage to the internal parts of the device.
