Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention provides a technical solution for a display repair device:

[0023] Embodiment:

[0024] As Figure 1 , Figure 2 and Figure 3 shown, it includes a chassis 1, a connecting rod 2 is connected to the side wall of the chassis 1, a connecting column 3 is arranged between two chassis 1, a connecting block 4 is sleeved outside the connecting column 3, one end of the connecting block 4 is connected to a flat plate 6, a plurality of through holes 7 are penetrated through the inner cavity of the flat plate 6, a first screw 8 is movably arranged in the inner cavity of the through hole 7, one end of the first screw 8 is connected to a pressing plate 9, a nut 11 is threadedly connected to the outer circle of the first screw 8, and an L-shaped limiting frame 28 is arranged between two connecting blocks 4.

[0025] Among them, a rubber block 10 is arranged at one end of the pressing plate 9, and the L-shaped limiting frame 28 is rotatably connected to the connecting column 3.

[0026] In this embodiment, the flat plate 6 is used for supporting the display. When in use, first rotate the L-shaped limiting frame 28 to make the L-shaped limiting frame 28 perpendicular to the connecting column 3, then place the display above the flat plate 6, and then when the flat plate 6 is rotated to an inclined state, at this time the L-shaped limiting frame 28 can limit the bottom of the display to prevent the display from slipping. Then insert the first screw 8 into the through hole 7 and rotate the nut 11 to clamp the display between the flat plate 6 and the pressing plate 9, thereby limiting the display and preventing the display from falling when the device is collided, so as to improve the use stability and safety of the device. At the same time, due to the setting of the rubber block 10, it can prevent the pressing plate 9 from causing extrusion damage to the surface of the display, and the overall practicability is relatively strong.

[0027] Among them, as Figure 1 shown, a plurality of through holes 7 are evenly distributed in a rectangle.

[0028] In this embodiment, since the first screw 8 can be removed from the inner cavity of the through hole 7, the distance between the four pressing plates 9 can be adjusted. At the same time, the L-shaped limiting frame 28 can move on the outer ring of the connecting column 3, so that the device can be applied to monitors of different sizes, expanding the use range of the device and further improving the practicability of the device.

[0029] Among them, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, an adjusting frame 15 is connected between the two connecting rods 2. A plurality of adjusting holes 16 are formed through the inner cavity of the adjusting frame 15, and a connecting ring 17 is arranged at one end of the adjusting hole 16.

[0030] Among them, a fixing block 19 is arranged at the bottom of the flat plate 6. One end of the fixing block 19 is connected with a first support rod 20. A support rod 21 is rotatably connected to the outer ring of the first support rod 20. One end of the support rod 21 is rotatably connected with a second support rod 22. Limiting grooves 23 are formed on both sides of the second support rod 22. A T-shaped connecting column 24 is rotatably connected to the inner cavity of the limiting groove 23. One end of the T-shaped connecting column 24 is connected with a limiting block 25. A second screw 26 is movably arranged in the inner cavity of the limiting block 25. One end of the second screw 26 is connected with a knob 27. The second screw 26 is threadedly movably connected with the connecting ring 17.

[0031] In this embodiment, when the flat plate 6 is rotated around the connecting column 3 to make the flat plate 6 inclined, at this time, the support rod 21 is rotated around the first support rod 20 until the limiting block 25 is perpendicular to one of the adjusting holes 16. Then, the second screw 26 is passed through the inner cavity of the limiting block 25, and the second screw 26 is rotated by the knob 27 to threadedly connect the second screw 26 with the connecting ring 17. At this time, the position of the flat plate 6 can be fixed, avoiding situations such as the collapse of the flat plate 6 during the repair of the display screen, further improving the use stability of the device; at the same time, since the limiting groove 23 and the T-shaped connecting column 24 are rotatably connected, the limiting block 25 can always be kept horizontal with the adjusting frame 15 through rotation adjustment. And since there are a plurality of adjusting holes 16 and they are evenly distributed on a straight line, it is convenient to adjust the inclination of the flat plate 6 to improve the use convenience of the device.

[0032] Among them, as Figure 1 , Figure 2 and Figure 3 shown, support feet 12 are connected to both sides of the chassis 1. Mounting holes 13 are formed through the inner cavities of the support feet 12. A buffer pad 14 is arranged at the bottom of the chassis 1.

[0033] In this embodiment, the supporting feet 12 are used to support the whole device. The mounting holes 13 can facilitate the installation of the device on an external moving or fixed platform, thereby facilitating the use of the device. The buffer pads 14 can absorb or weaken the vibration force transmitted upward by the device supporting platform, thereby reducing the impact of vibration on the display and further enhancing the practicality of the device.

[0034] In the description of the present utility model, it should also be noted that, unless otherwise clearly defined and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0035] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
