In the middle of one side of the fixing frame, a liquid crystal display is installed. And at the four corners of the fixing frame, the fixing blocks and the connecting plates are fixed to each other through a number of fixing bolts of the clamping plate assembly. On one side of the opposite fixing blocks, connecting frames of the connecting component are fixedly connected. And the connecting frames are U-shaped. And in the middle of the lower side plates of the opposite U-shaped connecting frames, guide columns are threadedly connected. In the middle of each guide column, a slider is fitted and slidably connected. Symmetrically, the upper ends of the sliders are fixedly connected with a pressurized cleaning component.

[0007] It should be noted in the solution that each clamping plate assembly includes a fixing block and a connecting plate. At one corner of the fixing block and the connecting plate, a number of connecting holes are provided. The number of the connecting holes is three, and they are distributed in a triangular shape. And a fixing bolt can be threadedly connected to each of the connecting holes.

[0009] Furthermore, it should be noted that several of the connecting frames are in two sections, and a first sliding groove is provided at the middle of the opposite surfaces of each section of the connecting frame. The first sliding grooves are all fitted and slidably connected to the outer surfaces of the first sliding plates fixedly connected to both ends of the sliding shaft.

[0010] As a preferred embodiment, the outer surfaces of the guide posts are all threadedly connected through the middle of the lower side plates of the U-shaped connecting frame and are embedded and slidably connected to the middle of the upper side plates of the U-shaped connecting frame.

[0011] As a preferred embodiment, each of the pressurized cleaning assemblies includes a fixing plate. Both ends of the fixing plate are fixedly connected to the upper ends of the symmetric sliders, and a plurality of first fixing shafts are fixedly connected to the lower ends of the fixing plate.

[0014] (1) First, fix the fixing block, the connecting plate, and the four corners of the fixing frame by the plurality of fixing bolts of the clamping plate assembly. Then, slowly rotate the symmetric guide posts into the lower side plates of the U-shaped connecting frames on the opposite sides, and at the same time, guide the symmetric sliders onto the outer surfaces of the symmetric guide posts until the symmetric guide posts stop entering the upper side plates of the U-shaped connecting frames on the opposite sides. Then, move the bottom plate upward and install the cleaning cloth, so that the upper end of the cleaning cloth is fixedly connected to the symmetric convex guides on the upper end of the bottom plate.

[0020] The present invention will be further described below in conjunction with embodiments.

[0021] Please refer to Figures 1-3 , the present invention provides a liquid crystal display screen with a cleaning mechanism, including: a fixed frame 1, a liquid crystal display screen 2 is installed in the middle of one side of the fixed frame 1, and the four corners of the fixed frame 1 are fixedly connected through a plurality of fixed bolts 304 of the clamping plate assembly 3, and the fixed block 301 and the connecting plate 302 are fixed to each other. On one side of the fixed block 301 on the opposite side, a connecting frame 401 of the connecting assembly 4 is fixedly connected, and the connecting frame 401 is U-shaped. At the middle of the lower side plate of the opposite U-shaped connecting frame 401, a guide post 5 is threadedly connected, and a slide block 6 is fitted and slidably connected to the middle of the guide post 5. The upper ends of the symmetric slide blocks 6 are fixedly connected to a pressurized cleaning assembly 7.

[0022] Furthermore, as Figure 2 shown, specifically, the clamping plate assemblies 3 each include a fixed block 301 and a connecting plate 302. A plurality of connecting holes 303 are provided at one corner of the fixed block 301 and the connecting plate 302. The number of the plurality of connecting holes 303 is three, and they are distributed in a triangular shape. A fixed bolt 304 can be threadedly connected to each of the plurality of connecting holes 303. Through the plurality of clamping plate assemblies 3, the cleaning mechanism can be fixed on the liquid crystal display screen 2, and the stability of the plurality of clamping plate assemblies 3 can be increased through the number and distribution of the plurality of connecting holes 303.

[0023] Furthermore, as Figure 2 shown, specifically, the opposite corners of the four connecting plates 302 are all arc-shaped, and a suction cup 305 is fixedly connected to one side of the lower surface of the four connecting plates 302. Through the shape of the four connecting plates 302, the cleaning process of the cleaning cloth 708 can be facilitated, and through the suction cup 305, the fixing stability with the fixed frame 1 can be increased, and direct fixing can be prevented from damaging the fixed frame 1.

[0024] Furthermore, as Figure 2As shown, it is worth specifically stating that several connecting frames 401 are each in two sections, and a first sliding groove 402 is provided in the middle of the opposite surfaces of each section of the connecting frame 401. The first sliding grooves 402 are all fitted and slidably connected to the outer surface of a first sliding plate 404 fixedly connected to both ends of a sliding shaft 403. Through the shape and connection relationship of the connecting frame 401, it can be applicable to liquid crystal display screens 2 of different longitudinal lengths, thereby increasing the practicality of the device.

[0025] This solution has the following working process: First, several fixing bolts 304 of the clamping plate assembly 3 are fixedly connected to fix the fixing block 301, the connecting plate 302, and the four corners of the fixing frame 1 to each other. Then, the symmetric guide posts 5 are slowly rotated into the lower side plates of the opposite U-shaped connecting frames 401, and at the same time, the symmetric sliders 6 are guided onto the outer surface of the symmetric guide posts 5 until the symmetric guide posts 5 stop when they enter the upper side plates of the opposite U-shaped connecting frames 401. Then, the bottom plate 706 is moved upward, and a cleaning cloth 708 is installed so that the upper end of the cleaning cloth 708 is fixedly connected to the symmetric convex guide 707 at the upper end of the bottom plate 706. Finally, the bottom plate 706 is released, and the pressurized cleaning assembly 7 is pulled up and down.

[0026] According to the above working process, it can be seen that: through several clamping plate assemblies 3, this cleaning mechanism can be fixed on the liquid crystal display screen 2, and through the quantity and distribution of several connecting holes 303, the stability of several clamping plate assemblies 3 can be increased. Through the shape of the four connecting plates 302, the cleaning process of the cleaning cloth 708 can be facilitated, and through the suction cups 305, both the fixing stability with the fixing frame 1 can be increased and direct fixing can be prevented from damaging the fixing frame 1. Through the shape and connection relationship of the connecting frame 401, it can be applicable to liquid crystal display screens 2 of different longitudinal lengths, thereby increasing the practicality of the device.

[0027] Furthermore, as Figure 2 shown, it is worth specifically stating that the outer surfaces of the guide posts 5 are all threadedly connected through the middle of the lower side plates of the U-shaped connecting frames 401 and are embedded and slidably connected to the middle of the upper side plates of the U-shaped connecting frames 401. Through the guide posts 5, the position and movement trajectory of the pressurized cleaning assembly 7 can be restricted, and at the same time, through the installation and disassembly method of the guide posts 5, the installation and disassembly of the entire cleaning mechanism are facilitated.

[0028] Furthermore, as Figure 3As shown, it is worth specifically explaining that the pressurized cleaning assembly 7 includes a fixed plate 701. Both ends of the fixed plate 701 are fixedly connected to the upper ends of the symmetric sliders 6, and several first fixed shafts 702 are fixedly connected to the lower end of the fixed plate 701. A second sliding plate 704 is fixedly connected to the lower ends of the several first fixed shafts 702. The outer surfaces of the second sliding plates 704 are fitted and slidably connected to the second sliding grooves 7031 provided in the middle of the upper ends of the second fixed shafts 703. Springs 705 are fixedly connected to the upper surfaces of the lower ends of the several second fixed shafts 703 and the lower ends of the corresponding second sliding plates 704. The lower ends of the several second fixed shafts 703 are fixedly connected to a bottom plate 706. Through the pressurized cleaning assembly 7, the cleaning cloth 708 can always be closely attached to the liquid crystal display screen 2, improving the cleaning efficiency of the cleaning cloth 708.

[0029] Furthermore, as Figure 3 shown, it is worth specifically explaining that the lower end of the bottom plate 706 is semicircular, and convex guides 707 are fixedly connected to both sides of the upper end of the bottom plate 706, and a cleaning cloth 708 is installed. Due to the shape of the bottom plate 706 and the convex guides 707 fixedly connected to both sides of its upper end, it is convenient for the installation and disassembly of the cleaning cloth 708.

[0030] In summary: First, the fixed block 301 and the connecting plate 302 are fixedly connected through the several fixing bolts 304 of the clamping plate assembly 3, and the four corners of the fixing frame 1 are fixed to each other. Then, the symmetric guide posts 5 are slowly rotated into the lower side plates of the opposite U-shaped connecting frames 401, and at the same time, the symmetric sliders 6 are guided onto the outer surfaces of the symmetric guide posts 5 until the symmetric guide posts 5 enter the upper side plates of the opposite U-shaped connecting frames 401 and stop. Then, the bottom plate 706 is moved upward, and the cleaning cloth 708 is installed so that the upper end of the cleaning cloth 708 is fixedly connected to the symmetric convex guides 707 at the upper end of the bottom plate 706. Finally, the bottom plate 706 is released, and the pressurized cleaning assembly 7 is pulled up and down. Through the guide posts 5, the position and movement trajectory of the pressurized cleaning assembly 7 can be restricted. At the same time, through the installation and disassembly method of the guide posts 5, the installation and disassembly of the entire cleaning mechanism are convenient. Through the pressurized cleaning assembly 7, the cleaning cloth 708 can always be closely attached to the liquid crystal display screen 2, improving the cleaning efficiency of the cleaning cloth 708. Due to the shape of the bottom plate 706 and the convex guides 707 fixedly connected to both sides of its upper end, it is convenient for the installation and disassembly of the cleaning cloth 708.
