DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] The present invention provides a high-speed transmission liquid crystal display screen, such as Figures 1 to 3 As shown, it includes a display screen body 1, an outer frame is arranged on the outer side of the display screen body 1, and the outer frame includes a rear plate 2 and two front plates 3. The top and bottom surfaces of the rear plate 2 are fixedly connected to the front plates 3 by connecting plates, and the top connecting plate is provided with a notch. The display screen body 1 is correspondingly plugged into the inner side of the outer frame through the notch, and the bottom surface of the display screen body 1 is fitted with the top surface of the bottom connecting plate. The surfaces of the two front plates 3 are provided with limiting components for limiting the display screen body 1, and the limiting components include a top strip 4 and a bottom strip 5. The rear side surface of the top strip 4 and the rear side surface of the bottom strip 5 are both fitted with the front side surface of the display screen body 1. The limiting components use the top strip 4 and the bottom strip 5 to make the rear side surface of the display screen body 1 fit with the front side surface of the rear plate 2. The limiting component is used to make the front side surface of the top strip 4 and the front side surface of the bottom strip 5 fit with the rear side surface of the front plate 3, and the display screen body 1 is placed on the inner side of the outer frame through the notch until the bottom surface of the display screen body 1 fits with the top surface of the bottom connecting plate. The limiting component drives the top strip 4 and the bottom strip 5 to approach the display screen body 1 until the rear side surfaces of the top strip 4 and the bottom strip 5 fit with the front side surface of the display screen body 1. Under the limiting mode of the limiting component, the top strip 4 and the bottom strip 5 cooperate with the rear plate 2 to preliminarily limit the display screen body 1, and display screen bodies 1 of different thicknesses can be limited.

[0030] The top strip 4 cooperates with the back plate 2 to define the top of the display screen body 1, and the bottom strip 5 cooperates with the back plate 2 to define the bottom of the display screen body 1, so that the display screen body 1 is always in a vertical state inside the outer frame, avoiding the display screen body 1 from being offset during installation, avoiding impact damage to the screen of the display screen body 1 and the front plate 3 due to tilting, and ensuring the stability of the display screen body 1 inside the outer frame.

[0031] exist Figure 1 , Figure 3 and Figure 4In the figure, the limiting component also includes two vertically parallel pressure plates 6, the two pressure plates 6 correspond to the two front plates 3 one by one, the pressure plates 6 are located at the front side of the front plate 3, and the top and bottom of the rear side of the pressure plate 6 are fixed with pressure rods 7 that penetrate the front plate 3. The pressure plate 6 is connected to the top bar 4 and the bottom bar 5 respectively by the two pressure rods 7, and a spring 8 is sleeved on the surface of the pressure rod 7, one end of the spring 8 is connected to the rear side of the pressure plate 6, and the other end of the spring 8 is connected to the front side of the front plate 3, and the spring 8 is in a stretched state. Pull the pressure plate 6 forward, and the forward pressure plate 6 uses the pressure rod 7 to pull the top bar 4 and the bottom bar 5 forward synchronously, and the forward pressure plate 6 cooperates with the front plate 3 to pull the spring 8 on the surface of the pressure rod 7 until the front side surface of the top bar 4 and the front side surface of the bottom bar 5 are in contact with the rear side surface of the front plate 3. After the display screen body 1 is placed on the inner side of the outer frame accordingly, slowly release the tension applied to the pressure plate 6, and the elastic force of the spring 8 makes the pressure plate 6 close to the front plate 3, and the pressure plate 6 uses the pressure rod 7 to make the top bar 4 and the bottom bar 5 close to the display screen body 1, until the rear side surface of the top bar 4 and the rear side surface of the bottom bar 5 are in contact with the front side surface of the display screen body 1. At this time, release the tension applied to the pressure plate 6, and the elastic force of the spring 8 makes the top bar 4 and the bottom bar 5 cooperate to squeeze the display screen body 1, so that the display screen body 1 is in a vertical state on the inner side of the outer frame.

[0032] exist Figure 5 and Figure 6 In the figure, vertical rods 9 are fixed to the top surfaces of both sides of the connecting plate at the bottom, and a ring 10 is sleeved on the surface of the vertical rod 9. A nut 11 is spirally sleeved on the top of the vertical rod 9, and the bottom surface of the nut 11 fits with the top surface of the ring 10. Push frames 12 are arranged on both sides of the display screen body 1, and the two push frames 12 correspond to the two rings 10 one by one, and a rotating plate 13 is arranged between the push frames 12 and the rings 10. The bottom end of the rotating plate 13 is hinged to the bottom of the outer side surface of the push frame 12, and the top end of the rotating plate 13 is hinged to the bottom of the outer side surface of the ring 10. After the display screen body 1 is vertically located inside the outer frame under the preliminary limitation of the top bar 4 and the bottom bar 5, the nut 11 is screwed, and the nut 11 moves downward on the surface of the vertical rod 9. The downwardly moved nut 11 pushes the collar 10 to move downward on the surface of the vertical rod 9, and the downwardly moved collar 10 pushes the top of the rotating plate 13 to move downward. Since the top of the rotating plate 13 is hinged with the collar 10, the rotating plate 13 rotates under the push of the collar 10, and the bottom end of the rotating rotating plate 13 pushes the push frame 12 to move on the top surface of the connecting plate at the bottom until the inner side of the push frame 12 is attached to the side of the display screen body 1. The spiral cooperation between the nut 11 and the vertical rod 9 allows the rotating rotating plate 13 to drive the push frame 12 to clamp display screen bodies 1 of different lengths, so that the display screen body 1 is stable on the inner side of the outer frame, and the display screen body 1 is prevented from deviating on the inner side of the outer frame or falling off from the inner side of the outer frame due to a simple collision.

[0033] The front side of the push frame 12 is fixed with a wedge 14, and both ends of the bottom bar 5 are fixed with an inclined plate 15, and the front side of the inclined plate 15 corresponds to the rear side of the wedge 14. When the moving push frame 12 moves down and approaches the display screen body 1 under the drive of the rotating plate 13, the push frame 12 drives the wedge 14 to approach the inclined plate 15, until the rear side of the wedge 14 fits with the front side of the inclined plate 15, and the push frame 12 continues to approach the display screen body 1, at this time, the push frame 12 drives the wedge 14 to move on the front side of the inclined plate 15, and uses the moving wedge 14 to squeeze the inclined plate 15, and the inclined plate 15 drives the bottom bar 5 to squeeze the bottom of the front side of the display screen body 1 under the action of pressure, and the bottom bar 5 uses the pressure rod 7 and the pressure plate 6 to make the top bar 4 squeeze the top of the front side of the display screen body 1, further improving the vertical effect of the display screen body 1 on the inner side of the outer frame, avoiding the display screen body 1 from shaking arbitrarily on the inner side of the outer frame due to simple impact, and ensuring the integration effect of the display screen body 1 and the outer frame.

[0034] exist Figure 5 In the embodiment, the outer side of the push frame 12 is fixed with a limiting sleeve 16, and the top surface of the bottom connecting plate is fixed with a cross bar 17, and the inner side end of the cross bar 17 is correspondingly plugged into the outer side end of the limiting sleeve 16. When the rotating rotating plate 13 pushes the push frame 12 to approach the display screen body 1, the push frame 12 slides on the surface of the cross bar 17 using the limiting sleeve 16, and the cross bar 17 cooperates with the limiting sleeve 16 to limit the push frame 12, so that the bottom surface of the push frame 12 fits with the top surface of the bottom connecting plate, so that the inner side of the push frame 12 always corresponds to the side of the display screen body 1. The spiral effect of the nut 11 and the vertical rod 9 facilitates the ring 10 to provide downward movement power for the rotation of the rotating plate 13, and facilitates the inner side of the push frame 12 to fit with the side of the display screen body 1. The cooperation and clamping of the two push frames 12 ensure that the display screen body 1 is in a stable state inside the outer frame.

[0035] Unscrew the nut 11 and pull the ring 10 up on the surface of the vertical rod 9. The upwardly moved ring 10 uses the rotating plate 13 to pull the push frame 12 away from the display screen body 1. The elastic force of the spring 8 makes the top bar 4 and the bottom bar 5 keep the display screen body 1 stable on the inner side of the outer frame.

[0036] exist Figure 5 and Figure 7In the embodiment, a plug-in frame 18 is provided on both sides of the display screen body 1. A protruding rod 19 is fixed on the outer side of the plug-in frame 18. A rotating sleeve 20 is spirally sleeved on the surface of the protruding rod 19. A clamping head 21 is fixed on the top of the outer side of the circumference of the collar 10. The outer end of the rotating sleeve 20 is rotatably clamped on the surface of the clamping head 21. When the collar 10 moves up and down on the surface of the vertical rod 9, the collar 10 drives the rotating sleeve 20 to move up and down synchronously by using the clamping head 21. Since the rotating sleeve 20 is spirally sleeved on the surface of the plug-in frame 18, the rotating sleeve 20 drives the plug-in frame 18 to move synchronously by using the protruding rod 19. When the rotating sleeve 20 is twisted, since the clamping head 21 is fixed on the outer side of the circumference of the collar 10, the spiral effect of the rotating sleeve 20 and the protruding rod 19 makes the plug-in frame 18 approach or move away from the collar 10, and the relative distance between the plug-in frame 18 and the collar 10 can be adjusted in real time.

[0037] exist Figure 5 , Figure 7 and Figure 8 In the embodiment, two opposite frame plates 22 are arranged on the side of the display screen body 1, and an inner plate 23 corresponding to the frame plates 22 is arranged at the center of the side of the display screen body 1. The two frame plates 22 are clamped on the front and rear sides of the inner plate 23, and a plug rod 24 is fixed on the surface of the frame plate 22. A slot corresponding to the plug rod 24 is arranged on the surface of the inner plate 23. Two vertical bars 25 are fixed on the inner side of the plug frame 18, and a vertical groove corresponding to the vertical bar 25 is arranged on the outer side of the frame plate 22. The two frame plates 22 are relatively located at the front and rear sides of the inner plate 23, so that the two frame plates 22 are close to each other. At this time, the frame plates 22 are close to the inner plate 23 until the insertion rods 24 on the frame plates 22 are inserted into the slots on the surface of the inner plate 23. At this time, the surface of the frame plates 22 is in contact with the inner plate 23. After the display screen body 1 carrying multiple frame plates 22 is placed on the inner side of the outer frame, the ring 10 is pushed down on the surface of the vertical rod 9. The downwardly moved ring 10 uses the clamping head 21 and the rotating sleeve 20 to drive the insertion frame 18 to move down synchronously, and the spiral cooperation of the rotating sleeve 20 and the clamping head 21 is used to make the vertical bars 25 of the insertion frame 18 correspond to the vertical grooves, until the vertical bars 25 on the inner side of the insertion frame 18 are correspondingly inserted into the inner side of the vertical grooves of the frame plates 22, and the insertion frame 18 uses the two vertical bars 25 to make the two frame plates 22 cooperate to clamp the front and rear sides of the inner plate 23, and the side of the display screen body 1 is defined by the insertion frame 18 and the two frame plates 22.

[0038] Under the cooperation and restriction of the rotating sleeve 20 and the clamping head 21, the inserting frame 18 further restricts the side of the display screen body 1 by using two frame plates 22, thereby further improving the stability of the display screen body 1 on the inner side of the outer frame.

[0039] Working principle of the present invention:

[0040] Reference Figures 1 to 8As shown, the two frame plates 22 are relatively located at the front and rear sides of the inner plate 23, so that the two frame plates 22 are close to each other. At this time, the frame plates 22 are close to the inner plate 23 until the insertion rod 24 on the frame plates 22 is inserted into the slot on the surface of the inner plate 23. At this time, the surface of the frame plates 22 is in contact with the inner plate 23.

[0041] Pull the pressure plate 6 forward, and the forward pressure plate 6 uses the pressure rod 7 to pull the top bar 4 and the bottom bar 5 forward synchronously, and the forward pressure plate 6 cooperates with the front plate 3 to pull the spring 8 on the surface of the pressure rod 7 until the front side surface of the top bar 4 and the front side surface of the bottom bar 5 are in contact with the rear side surface of the front plate 3. After placing the display screen body 1 carrying multiple frame plates 22 on the inner side of the outer frame, slowly release the tension applied to the pressure plate 6, and the elastic force of the spring 8 makes the pressure plate 6 close to the front plate 3, and the pressure plate 6 uses the pressure rod 7 to make the top bar 4 and the bottom bar 5 close to the display screen body 1, until the rear side surface of the top bar 4 and the rear side surface of the bottom bar 5 are in contact with the front side surface of the display screen body 1. At this time, release the tension applied to the pressure plate 6, and the elastic force of the spring 8 makes the top bar 4 and the bottom bar 5 cooperate to squeeze the display screen body 1, so that the display screen body 1 is in a vertical state on the inner side of the outer frame.

[0042] When the collar 10 moves up and down on the surface of the vertical rod 9, the collar 10 drives the rotating sleeve 20 to move up and down synchronously by using the clamping head 21. Since the rotating sleeve 20 is spirally sleeved on the surface of the plug-in frame 18, the rotating sleeve 20 drives the plug-in frame 18 to move synchronously by using the protruding rod 19. When the rotating sleeve 20 is twisted, since the clamping head 21 is fixed on the outer side of the circumference of the collar 10, the spiral effect of the rotating sleeve 20 and the protruding rod 19 makes the plug-in frame 18 approach or move away from the collar 10, and the relative distance between the plug-in frame 18 and the collar 10 is adjusted in real time, so that the vertical bar 25 of the plug-in frame 18 corresponds to the vertical groove, until the vertical bar 25 on the inner side of the plug-in frame 18 is correspondingly inserted into the inner side of the vertical groove of the frame plate 22, and the plug-in frame 18 uses two vertical bars 25 to make the two frame plates 22 cooperate to clamp the front and rear sides of the inner plate 23, and the side of the display screen body 1 is defined by the cooperation between the plug-in frame 18 and the two frame plates 22.

[0043] The nut 11 is screwed, and the nut 11 moves downward on the surface of the vertical rod 9. The downwardly moved nut 11 pushes the collar 10 to move downward on the surface of the vertical rod 9, and the downwardly moved collar 10 pushes the top of the rotating plate 13 to move downward. Since the top of the rotating plate 13 is hinged with the collar 10, the rotating plate 13 rotates under the push of the collar 10. The bottom end of the rotating rotating plate 13 pushes the push frame 12 to move on the top surface of the bottom connecting plate. The push frame 12 slides on the surface of the cross bar 17 using the limiting sleeve 16, and the cross bar 17 cooperates with the limiting sleeve 16 to limit the push frame 12, so that the push frame 1 The bottom surface of the push frame 12 is fitted with the top surface of the bottom connecting plate, so that the inner side surface of the push frame 12 always corresponds to the side surface of the display screen body 1, until the inner side surface of the push frame 12 is fitted to the side surface of the display screen body 1, and the rotating rotating plate 13 drives the push frame 12 to clamp the display screen bodies 1 of different lengths by the spiral cooperation between the nut 11 and the vertical rod 9, so that the display screen body 1 is stable inside the outer frame, and the display screen body 1 is prevented from deviating inside the outer frame or falling from the inner side of the outer frame due to a simple collision, thereby completing the limitation of the display screen body 1.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
