Description
Technical Field
[0001] The utility model belongs to the technical field of reflection screens, and in particular relates to a reflection screen which is convenient to assemble. Background Art
[0002] The reflective screen is a screen that is equipped with reflective material under the LCD panel to replace the luminous material of the transmissive display screen. When the ambient light is sufficient, it uses the light reflected by the mirror surface to illuminate the screen. However, it cannot display in dark places because the weak ambient light is not enough to be reflected to illuminate the screen. This display screen that passively receives reflected ambient light is a passive reflective LCD screen. Color screen PDAs do not use passive reflective displays.
[0003] The "active" reflective screen corresponding to the "passive anti-" reflective screen is equivalent to adding a light source on the top of the "passive" reflective LCD screen for illumination. In this way, even when the ambient light is insufficient, you can turn on the light to see a clear and bright screen.
[0004] The reflective screen usually requires complex fixing structures and load-bearing structures during installation, which makes the reflective screen very inconvenient to assemble. Utility Model Content

[0025] In this embodiment, by providing a limit groove on the top of the fixed box 3, and the limit groove is slightly smaller than the limit card 16, the limit card 16 can be stuck in the limit groove to fix the movable cover 15. By dividing the friction clamp 6 into two groups, one group is installed in a regular triangle, and the other group is installed in an inverted triangle, when installing the reflective screen 1, the friction clamp 6 can generate a relative force to clamp the protrusion 21 and the groove 7. By sliding the sliding clamp 9 in the sliding groove 13, the connecting platform 2 can be fixed in the fixed box 3. By installing the protrusion 21 in the groove 7, the connecting platform 2 can be fixed in the fixed box 3. In the embodiment, the threaded rod 4 is threadedly connected to the threaded hole 8, so that the reflective screen 1 can be connected to the connecting platform 2. The two supporting feet 20 which are relatively perpendicular to the fixing box 3 can make the whole device stably placed on the ground. The four threaded rods 4 which are installed in a rectangular array inside the clamping protrusion 21 can make the reflective screen 1 threadedly connected to the connecting platform 2 through the threaded rods 4, so that the reflective screen 1 and the connecting platform 2 are fixed more firmly. The rectangular reinforcement block is installed between the fixing box 3 and the telescopic rod 17, so that the fixing box 3 and the telescopic rod 17 can be connected more firmly.
[0026] Specifically, a limiting groove is opened on the top of the fixed box 3, and the limiting groove is slightly smaller than the limiting card 16.

[0027] Specifically, a friction clamp 6 is also installed on one side of the reflective screen 1, and the friction clamp 6 is divided into two groups, one group is installed in a regular triangle, and the other group is installed in an inverted triangle. By dividing the friction clamp 6 into two groups, one group is installed in a regular triangle, and the other group is installed in an inverted triangle, a relative force can be generated by the friction clamp 6 when the reflective screen 1 is installed, so that the clamping protrusion 21 and the clamping groove 7 are clamped.
[0028] Specifically, the sliding card member 9 can be slidably installed in the sliding card slot 13 . By sliding the sliding card member 9 in the sliding card slot 13 , the connecting platform 2 can be fixed in the fixing box 3 .
[0029] Specifically, the protrusion 21 can be stuck in the slot 7, and the threaded rod 4 is threadedly connected to the threaded hole 8. By installing the protrusion 21 in the slot 7 and threading the threaded rod 4 to the threaded hole 8, the reflective screen 1 can be connected to the connecting platform 2.
[0030] Specifically, there are two supporting legs 20 , which are relatively perpendicular to the fixing box 3 . The two supporting legs 20 , which are relatively perpendicular to the fixing box 3 , can stably place the entire device on the ground.
[0031] Specifically, there are four threaded rods 4, which are installed in a rectangular array inside the protrusion 21. Through the four threaded rods 4 installed in a rectangular array inside the protrusion 21, the reflective screen 1 can be threadedly connected to the connecting platform 2 through the threaded rods 4, so that the reflective screen 1 and the connecting platform 2 are fixed more firmly.
[0032] Specifically, a rectangular reinforcement block is installed between the fixed box 3 and the telescopic rod 17. By installing the rectangular reinforcement block between the fixed box 3 and the telescopic rod 17, the connection between the fixed box 3 and the telescopic rod 17 can be made more stable.
[0033] The working principle or use process of the utility model: when the utility model is in use, the fixed box 3 is first placed on the ground through the supporting feet 20 and the supporting rods 17, and then the threaded rod 18 is rotated by turning the handle 19 to move outward, so that the telescopic rod 17 can be extended and retracted, and the reflective screen 1 is inserted into the inside of the card slot 7 through the card convex 21. During the clamping process, the friction between the card parts 6 makes the card slot 7 and the card convex 21 more tightly clamped, and then the nut 6 is rotated to rotate the threaded rod 4, so that the threaded rod 4 enters the threaded hole 8, thereby fixing the reflective screen 1 and the connecting platform 2, and the bolt 12 passes through the fixed platform 10, the fastener 11, and the fixed box 3 to fix the fixed platform 10 to the inner wall of the fixed box 3, and then the movable cover 15 is opened through the hinge 14, and the reflective screen 1 and the connecting platform 2 are moved to clamp the sliding card 9 into the movable card slot 13 from above and clamp it, and then the movable cover 15 is covered by the hinge 14, and the limit card 16 clamps the limit slot to fix the movable cover 15, wherein the electrical equipment in this device is all externally connected to the power supply and the operation and shutdown are controlled by the matching control switch.
