Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal screen fixing frames, in particular to a liquid crystal screen fixing iron frame. Background Art

[0002] Liquid crystal screens use liquid crystal materials as basic components. Liquid crystal materials are filled between two parallel plates. Voltage is used to change the arrangement of molecules inside the liquid crystal material to achieve the purpose of light shielding and light transmission to display images of varying depths and in an orderly manner. In addition, as long as a three-primary color filter layer is added between the two plates, color images can be displayed. Liquid crystal screens have very low power consumption, so they are favored by engineers and are suitable for electronic devices using batteries.

[0003] In order to protect the LCD screen, a fixing frame is installed around it. However, when many existing LCD screen fixing frames are in use, the heat sinks on the sides thereof will accumulate a lot of dust over time. The dust will clog the heat sinks and affect their normal heat dissipation, which will have a certain impact on the LCD screen and cannot meet people's needs. Therefore, a LCD screen fixing iron frame is needed. Utility Model Content

[0004] The utility model aims to solve the problem of the LCD screen fixing frame in the prior art, overcome the shortcomings of the prior art, and design an LCD screen fixing iron frame whose heat dissipation plate can be disassembled for cleaning.

[0005] In order to achieve the above purpose, the technical solution of the utility model is:

[0006] A liquid crystal screen fixing iron frame comprises a first frame body, a rotating rod is rotatably connected to the side surface of the first frame body, a nut is threadedly connected to the surface of the rotating rod, a rotating plate is fixedly connected to the rear end of the rotating rod, a convex rod is fixedly connected to the surface of the rotating plate, a transmission plate is slidably connected to the surface of the convex rod, a breathable plate is engaged with the interior of the transmission plate, a connecting plate is slidably connected to the inner wall of the first frame body, and a second frame body is fixedly connected to the rear end of the connecting plate.

[0007] Preferably, a connecting block is fixedly connected to the back of the connecting plate, a screw rod is rotatably connected to the side of the connecting block, a connecting plate is fixedly connected to the back of the second frame, and a buffer pad is fixedly connected to the inner walls of the first frame and the second frame.

[0008] Preferably, the rotating rod is vertically arranged to the side surface of the first frame body, and the rotating rod is fixed by a nut.

[0009] Preferably, the convex rod is arranged offset from the rotation center point of the rotating plate, and the convex rod is embedded in the transverse sliding groove inside the transmission plate and is slidably connected thereto.

[0010] Preferably, air-permeable plates are attached to the sides of the first frame and the second frame, and the air-permeable plates are fixed to the sides of the first frame and the second frame through transmission plates.

[0011] Preferably, a transverse groove slide groove matching the size of the connecting block is provided on the back side of the second frame, and the connecting block passes through the transverse groove and is connected to the screw rod.

[0012] Preferably, the screw rod and the connecting plate are threadedly connected, and the connecting block forms a sliding structure through the screw rod.

[0013] The utility model has the following beneficial effects:

[0014] 1. By setting a breathable plate, when the fixed frame is installed on the LCD screen, the heat dissipated by the LCD screen can be dissipated to avoid damage to the LCD screen caused by high temperature. Since the breathable plate is used for a long time, a lot of dust will adhere to its surface. When the heat dissipation is affected, the nut can be loosened and the rotating rod can be controlled to rotate, and the rotating plate will rotate accordingly. Because the protruding rod is set away from the rotation center point of the rotating plate, when the protruding rod rotates, it will slide along the inner wall of the transmission plate and exert a pulling force upward on it. By setting the transmission plate, when it slides upward, it will gradually break away from the breathable plate. At this time, the breathable plate loses the clamping force of the transmission plate and can be removed from the side of the first frame for cleaning.

[0015] 2. By setting a screw rod, when it is necessary to adjust the distance between the first frame and the second frame, it is only necessary to twist the screw rod. Since the screw rod and the connecting plate are threadedly connected, when the screw rod rotates, it will slide sideways along the connecting plate and drive the connecting block connected to its own rotation to move synchronously. Since the connecting block and the connecting plate are fixedly connected, when the connecting block moves, the connecting plate moves accordingly and starts to slide inside the first frame, and the second frame fixedly connected to the connecting plate moves accordingly, thereby achieving the purpose of adjusting the distance between the first frame and the second frame.

[0021] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model. Example

[0022] like Figure 1 As shown, the utility model proposes an iron frame for fixing a liquid crystal screen, comprising a first frame body 1, a rotating rod 2 is rotatably connected to the side of the first frame body 1, a nut 3 is threadedly connected to the surface of the rotating rod 2, a rotating plate 4 is fixedly connected to the tail of the rotating rod 2, a convex rod 5 is fixedly connected to the surface of the rotating plate 4, a transmission plate 6 is slidably connected to the surface of the convex rod 5, a breathable plate 7 is clamped inside the transmission plate 6, a connecting plate 8 is slidably connected to the inner wall of the first frame body 1, and a second frame body 9 is fixedly connected to the tail of the connecting plate 8.

[0023] Furthermore, the rotating rod 2 is vertically arranged to the side of the first frame 1, and the rotating rod 2 is fixed by the nut 3. The nut 3 is loosened and the rotating rod 2 is controlled to rotate, and the rotating plate 4 rotates accordingly. Under the action of the nut 3, the rotating rod 2 can be limited.

[0024] Furthermore, the protruding rod 5 is set to deviate from the rotation center point of the rotating plate 4, and the protruding rod 5 is embedded in the transverse sliding groove inside the transmission plate 6 and is slidably connected thereto. Because the protruding rod 5 is set to deviate from the rotation center point of the rotating plate 4, when the protruding rod 5 rotates, it will slide along the inner wall of the transmission plate 6 and apply an upward pulling force to it.

[0025] Furthermore, air-permeable plates 7 are attached to the sides of the first frame 1 and the second frame 9, and the air-permeable plates 7 form a fixed structure on the sides of the first frame 1 and the second frame 9 through the transmission plate 6. By setting the transmission plate 6, when it slides upward, it will gradually lose contact with the air-permeable plate 7. At this time, the air-permeable plate 7 loses the clamping force of the transmission plate 6 and can be removed from the side of the first frame 1 for cleaning. Example

[0026] like Figure 1-4 As shown, the back of the connecting plate 8 proposed by the utility model is fixedly connected with a connecting block 10, the side of the connecting block 10 is rotatably connected with a screw rod 11, the back of the second frame 9 is fixedly connected with a connecting plate 12, and the inner walls of the first frame 1 and the second frame 9 are fixedly connected with a buffer pad 13.

[0027] Furthermore, a transverse groove that matches the size of the connecting block 10 is provided on the back of the second frame 9, and the connecting block 10 passes through the transverse groove and is connected to the screw rod 11. By providing the transverse groove, the connecting block 10 can be limited when it slides.

[0028] Furthermore, the screw rod 11 and the connecting plate 12 are threadedly connected, and the connecting block 10 forms a sliding structure through the screw rod 11. Since the connecting block 10 and the connecting plate 8 are fixedly connected, when the connecting block 10 moves, the connecting plate 8 moves accordingly and starts to slide inside the first frame 1, and the second frame 9 fixedly connected to the connecting plate 8 moves accordingly, thereby achieving the purpose of adjusting the distance between the first frame 1 and the second frame 9.

[0029] Working principle: First, by setting the air permeable plate 7, when the fixed frame is installed on the LCD screen, the heat dissipated by the LCD screen can be dissipated to avoid damage to the LCD screen caused by high temperature. Due to the long-term use of the air permeable plate 7, a lot of dust will adhere to its surface, which will affect its heat dissipation. The nut 3 can be loosened, and the rotating rod 2 can be controlled to rotate, and the rotating plate 4 will rotate accordingly. Because the convex rod 5 is set away from the rotation center point of the rotating plate 4, when the convex rod 5 rotates, it will slide along the inner wall of the transmission plate 6 and apply a pulling force upward to it. By setting the transmission plate 6, when it slides upward, it will gradually break away from the contact with the air permeable plate 7. At this time, the air permeable plate 7 loses the clamping force of the transmission plate 6 and can be removed from the side of the first frame 1 for cleaning.

[0030] Next, when it is necessary to adjust the distance between the first frame 1 and the second frame 9, it is only necessary to twist the screw rod 11. Since the screw rod 11 and the connecting plate 12 are threadedly connected, when the screw rod 11 rotates, it will slide sideways along the connecting plate 12 and drive the connecting block 10 connected to its own rotation to move synchronously. Since the connecting block 10 and the connecting plate 8 are fixedly connected, when the connecting block 10 moves, the connecting plate 8 moves accordingly and starts to slide inside the first frame 1, and the second frame 9 fixedly connected to the connecting plate 8 moves accordingly, thereby achieving the purpose of adjusting the distance between the first frame 1 and the second frame 9.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
