[0013] Further, the lower right end of the inner frame of the display panel is fixedly connected to a fixed rubber ring. The right end surface of the second rotating shaft is fixedly connected to a moving rubber ring.

[0014] A display with a liquid crystal display panel includes a display back shell fixedly connected to the back of the outer frame of the display panel, and a mounting mechanism.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) In this solution, the anti-peeping thin plate is used to enable the light emitted by the display panel to radiate only in the front direction, ensuring that the displayed content is only visible to the personnel directly in front. Effectively restricting the light leakage from the side, thus avoiding the personnel on both sides of the display panel from peeping at the displayed information, achieving the anti-peeping effect, and while protecting privacy, due to the small occlusion area, reducing the loss of display brightness.

[0020] (2) In this solution, when an unrelated person is directly behind the display panel, the anti-peeping angle can be flexibly adjusted at multiple angles by adjusting the orientation of the anti-peeping thin plate, enhancing the comprehensiveness and adaptability of the anti-peeping effect, and further improving the more comprehensive anti-peeping effect.

[0021] (3) In this solution, since the diameter of the first gear is larger than that of the second gear, according to the speed ratio principle of gear transmission, when the second gear drives the first gear to rotate, the rotation speed of the first gear will be lower than that of the second gear, effectively restricting the too fast rotation speed of the anti-peeping thin plate, thereby improving the accuracy and stability during the adjustment of the anti-peeping thin plate, improving the anti-peeping effect while enhancing the viewing experience.

[0022] (4) In this solution, the display is quickly and firmly installed by clamping the display device housing with the expansion plate and the mounting frame. Avoiding the need to drill additional holes on the surface of the device housing, effectively reducing the damage to the housing, eliminating the gaps generated during the screw installation step, ensuring the good sealing performance of the device. In addition, even if the rotating cap is rotated in the reverse direction, the fixed installation of the display cannot be released, further enhancing the stability of the installation.

[0023] (5) In this solution, when the expansion plate extends out of the display back shell, the third spring drives the two expansion plates to expand respectively, which can increase the effective contact area with the device housing when clamping and fixing the device housing, thereby dispersing the clamping force and reducing the risk of deformation of the device housing caused by excessive clamping force. At the same time, the larger contact area also correspondingly increases the friction force, further enhancing the stability of the installation. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0038] 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.

[0039] Please refer to Figures 1-7 , a liquid crystal display panel, including an outer frame 2 of the display panel, and an inner frame 3 of the display panel is fixedly connected inside the outer frame 2 of the display panel;

[0040] An anti-peeping mechanism, the anti-peeping mechanism is arranged inside and outside the inner frame 3 of the display panel, the anti-peeping mechanism includes an anti-peeping thin plate 301 arranged inside the inner frame 3 of the display panel, a slat 324 is fixedly connected to the bottom inner wall of the inner frame 3 of the display panel, the upper end of the slat 324 is rotatably connected to a second vertical shaft 323, and the anti-peeping thin plate 301 can make the light emitted by the display panel radiate only in the forward direction, so as to provide an anti-peeping effect. The front end of the inner frame 3 of the display panel is fixedly connected to an outer glass 1 of the display panel;

[0041] A first vertical shaft 322 is fixedly connected to the front side of the lower end of the anti-peeping thin plate 301. A sliding groove 313 is formed in the lower right end of the inner layer frame 3 of the display panel. A slider 312 is slidably connected inside the sliding groove 313. A connecting rod 314 is movably inserted into the slider 312. The first vertical shaft 322 is rotatably connected to the surface of the connecting rod 314. The number of the second vertical shaft 323 and the first vertical shaft 322 is multiple. A second spring 316 is fixedly connected to the lower right end of the inner side of the display panel inner layer frame 3. The right end of the second spring 316 is fixedly connected to a support circular plate 315. The second spring 316 can push multiple anti-peeping thin plates 301 to rotate rightward. The support circular plate 315 is fixedly sleeved on the surface of the connecting rod 314. A second rotating shaft 317 is rotatably connected to the lower right end of the display panel inner layer frame 3. The right end of the second rotating shaft 317 is fixedly connected to a winding shaft 303. The drawstring 305 can be wound by the winding shaft 303. The right end of the connecting rod 314 is fixedly connected to a drawstring 305. The orientation of the anti-peeping thin plate 301 can be adjusted by pulling the connecting rod 314 through the drawstring 305. The right end of the drawstring 305 is fixedly connected to the surface of the winding shaft 303.

[0042] Among them, a guide rail 308 is fixedly connected to the lower right end of the inner layer frame 3 of the display panel. A moving frame 307 is slidably connected to the surface of the guide rail 308. A steering support shaft 306 is rotatably connected to the right end of the moving frame 307. The transmission direction of the force of the drawstring 305 can be changed through the steering support shaft 306 so as to cooperate with the knob 302 to realize external driving of the anti-peeping thin plate 301. A first support plate 309 is fixedly connected to the upper surface of the moving frame 307. A second support plate 311 is fixedly connected to the lower right end of the display panel inner layer frame 3. A first spring 310 is fixedly connected between the first support plate 309 and the second support plate 311. When the drawstring 305 is released by loosening the winding shaft 303, the first spring 310 can drive the steering support shaft 306 to rotate forward to return to its original position so as to prevent the drawstring 305 from detaching from the steering support shaft 306.

[0043] Among them, the right lower end of the inner frame 3 of the display panel is rotatably connected to a first rotating shaft 304. The right end of the surface of the first rotating shaft 304 is fixedly connected to a second gear 321. The right end of the surface of the winding shaft 303 is fixedly connected to a first gear 320. The first gear 320 meshes with the second gear 321. The right end of the first rotating shaft 304 is fixedly connected to a knob 302. The diameter of the second gear 321 is smaller than that of the first gear 320, so that when the second gear 321 drives the first gear 320 to rotate, the rotation speed of the first gear 320 can be lower than that of the second gear 321, thereby preventing the anti-peeping thin plate 301 from rotating too fast. The right lower end of the inner frame 3 of the display panel is fixedly connected to a fixed rubber ring 318. The right end of the surface of the second rotating shaft 317 is fixedly connected to a moving rubber ring 319. Since the fixed rubber ring 318 and the moving rubber ring 319 are in close contact, the friction force between the fixed rubber ring 318 and the moving rubber ring 319 can keep the second rotating shaft 317 fixed in any state when it rotates.

[0044] By adopting the above technical solution, the light emitted by the display panel can only radiate forward through multiple longitudinally arranged anti-peeping thin plates 301, so that the information displayed on the display panel can only be seen by the people directly in front, and is prevented from being seen by the people on both sides, thereby achieving a good anti-peeping effect, and without directly blocking the display panel, the loss of the brightness of the display panel can be reduced.

[0045] By rotating the knob 302, the first rotating shaft 304 can be driven to rotate, and the second gear 321 can be synchronously driven to rotate. When the second gear 321 rotates, the first gear 320 can be driven to rotate. Then, the winding rope 305 can be wound by the winding shaft 303. The connecting rod 314 can be pulled to move to the right by the winding rope 305, and multiple anti-peeping thin plates 301 can be driven to rotate to the right with the second vertical shaft 323 as the axis. When the knob 302 is rotated in the opposite direction, the winding rope 305 can be loosened, and the connecting rod 314 can be pushed to move to the right by the second spring 316 in the compressed state, so that multiple anti-peeping thin plates 301 can rotate to the right with the second vertical shaft 323 as the axis. Through the above operations, the orientation angle of the anti-peeping thin plate 301 can be adjusted, thereby controlling the anti-peeping orientation of the display panel. When there are irrelevant people directly behind, the anti-peeping orientation can be adjusted, so as to realize the multi-angle adjustment of the anti-peeping orientation, further providing a better anti-peeping effect. And the diameter of the first gear 320 is larger than that of the second gear 321, so that when the second gear 321 drives the first gear 320 to rotate, the rotation speed of the first gear 320 can be lower than that of the second gear 321, thereby preventing the anti-peeping thin plate 301 from rotating too fast, improving the adjustment accuracy of the anti-peeping thin plate 301, and further improving the anti-peeping effect.

[0046] Please refer to Figures 8-12, a display with a liquid crystal display panel, including a display back shell 4 fixedly connected to the back of the outer frame 2 of the display panel, and an installation mechanism. The installation mechanism is arranged at the corners of the display back shell 4. The installation mechanism includes a support vertical plate 408 fixedly connected to the inner corners of the display back shell 4. A connecting block 405 is slidably sleeved at the rear end of the support vertical plate 408. A moving frame 404 is slidably sleeved on the surface of the connecting block 405. A screw rod 407 is threadedly inserted at one end of the moving frame 404 close to the outside of the display back shell 4. The front end of the screw rod 407 is rotatably connected to a guide frame 409. The guide frame 409 is inserted into the inside of the support vertical plate 408. A traction rope 410 is sleeved at the front end of the screw rod 407. An installation frame 401 is fixedly sleeved on the surface of the outer frame 2 of the display panel. A sealing strip 402 is fixedly connected to the back of the installation frame 401. The sealing strip 402 can improve the sealing effect after the display screen is installed.

[0047] Among them, a third rotating shaft 411 is rotatably inserted at the corner of the installation frame 401. The third rotating shaft 411 can wind up the traction rope 410. One end of the traction rope 410 close to the outside of the display back shell 4 is fixedly connected to the rear end of the third rotating shaft 411. The traction rope 410 can pull the third gear 413 to mesh with the fourth gear 414. The front end of the screw rod 407 is fixedly connected to the third gear 413. The rear end of the third rotating shaft 411 is fixedly connected to a fourth gear 414 that cooperates with the third gear 413. The fourth gear 414 drives the third gear 413 to rotate, and the screw rod 407 can drive the expansion plate 406 to abut against the inner wall of the equipment shell.

[0048] Among them, a rotating cap 412 is fixedly connected to the front end of the third rotating shaft 411. An internal hexagonal groove 420 is formed on the surface of the rotating cap 412. A connecting piece 415 is fixedly connected to one end of the moving frame 404 close to the outside of the display back shell 4. The connecting pieces 415 are grouped in pairs. A fourth rotating shaft 416 is rotatably connected to the inside of the connecting piece 415. An expansion plate 406 is fixedly connected to the front end of the fourth rotating shaft 416. By clamping the equipment shell with the expansion plate 406 and the installation frame 401, the rapid installation of the display can be realized.

[0049] Among them, a first square plate 417 is fixedly connected to the arc surface at the rear end of the fourth rotating shaft 416. A second square plate 418 is fixedly connected to the rear surface of the connecting piece 415. A third spring 419 is fixedly connected between the first square plate 417 and the second square plate 418. The third spring 419 can pull the two expansion plates 406 to expand respectively. A stop shaft 403 is rotatably connected to the corner of the display back shell 4.

[0050] When installing the display by adopting the above technical solution, the display is installed on the housing of the device, and the display panel of the display is exposed. Therefore, an installation opening larger than the back shell 4 of the display and smaller than the installation frame 401 needs to be opened on the housing of the device to be installed. Then, the back shell 4 of the display is set in the installation opening, and the sealing strip 402 is pressed against the outer surface of the device housing. Then, an inner hexagon wrench is used to rotate the rotary cap 412, so as to drive the third rotating shaft 411 to rotate and wind up the traction rope 410 at the same time, and the screw rod 407 can be pulled to move towards the direction close to the third rotating shaft 411 until the third gear 413 meshes with the fourth gear 414. At this time, the expansion plate 406 extends out of the back shell 4 of the display. Continuing to rotate the third rotating shaft 411, the fourth gear 414 can drive the third gear 413 to rotate, and then drive the screw rod 407 to rotate, so that the moving frame 404 moves forward until the expansion plate 406 abuts against the inner wall of the device housing. By clamping the device housing with the expansion plate 406 and the installation frame 401, the quick installation of the display can be realized, and there is no need to open additional screw holes on the surface of the device, reducing the damage to the device housing and the gap during screw installation, so as to maintain the sealing performance of the device, and the installation of the display cannot be released by rotating the rotary cap 412 in the reverse direction, further improving the installation stability.

[0051] Since the third spring 419 is in a stretched state, after the expansion plate 406 extends out of the back shell 4 of the display and disengages from between the two stop shafts 403, the third spring 419 pulls the two expansion plates 406 to rotate in the direction away from each other, so that the two expansion plates 406 are respectively expanded. When clamping the device housing, the contact area with the device housing can be increased, the probability of deformation of the device housing caused by excessive clamping force can be reduced, and the friction force can be increased to improve the installation stability.

[0052] Usage method: Set the back shell 4 of the display in the installation opening, and then use an inner hexagon wrench to rotate the rotary cap 412 to drive the third rotating shaft 411 to wind up the traction rope 410, so that the third gear 413 meshes with the fourth gear 414, and the expansion plate 406 also extends out and expands from the back shell 4 of the display. Continuing to rotate the third rotating shaft 411, the screw rod 407 drives the moving frame 404 to move forward, so that the expansion plate 406 abuts against the inner wall of the device housing, realizing the installation of the display.

[0053] When in use, rotating the knob 302 drives the first rotating shaft 304 to rotate, and the pull rope 305 can be wound up by the winding shaft 303, so as to pull the connecting rod 314 to move to the right, and the anti-peeping thin plate 301 can be driven to rotate to the right. Rotating the knob 302 in the opposite direction, the second spring 316 can push the connecting rod 314 to move to the right, so that the plurality of anti-peeping thin plates 301 rotate to the right, controlling the anti-peeping orientation of the display panel.

[0054] The above are only the preferred specific embodiments of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and its improved concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
