AI Technical Summary
In existing technologies, displays driven by servo motors cannot be effectively fixed when power is off or the power supply is interrupted, resulting in sliding and displacement, and making it impossible to effectively position the screen.
The system employs a combination structure of limit blocks, rotating rods, and conch turntables. The rotating rods drive the conch turntables to rotate, and the gradual thickness of the conch turntables and the fitting grooves compress the arrow push blocks to achieve omnidirectional positioning of the limit blocks. Combined with the elastic wires and the elastic pull of the push plate, multi-directional positioning without screws or servo motors is achieved.
It enables multi-directional and multi-angle positioning of the limit block even without power, avoiding sliding offset and improving screen stability and positioning accuracy.

Description
Technical Field
[0001] This invention belongs to the field of dual-screen transfer technology, specifically a dual-screen movable track device. Background Technology
[0002] A mobile screen is a display screen that can slide on a track. It is a new type of multimedia display method. Display panels or LCD video walls are arranged on a coordinate axis-like display wall as a background wall. At the same time, a set of sliding mounting plates and other mechanical structures are installed in front to suspend the LCD screen. Sensors are pre-positioned at different positions on the background wall. When the audience pushes the LCD screen to move on the track, the LCD screen will automatically play the corresponding content each time it senses a touch. The content can be pictures, text or video.
[0003] A patent with publication number CN218762391U discloses a mobile screen device controlled by a dual-track system, including a horizontal track and a display screen. The display screen is fixedly connected to the front side of a mounting plate. A base plate is slidably connected to the horizontal track. A ring track is fixedly connected to the front side of the base plate. A track groove is provided on the back of the mounting plate at a position corresponding to the ring track. The ring track is slidably connected in the track groove. A drive mechanism is provided on the mounting plate and located on the side wall of the track groove. By pushing the base plate, the display screen can slide. By rotating the drive gear and the transmission of the ring rack, the display screen can rotate on the ring track, realizing dual-track control of the mobile screen so that the mobile screen can have a comprehensive display effect.
[0004] In current technologies, existing horizontal tracks and displays are generally moved using servo motors. While the movement of the display by the motor is manually controlled, it cannot make small-range adjustments to the position. Furthermore, the motor requires electricity for control. This means that the fixation between the two screens can only be achieved by the servo motor. If the servo motor experiences a power outage or a disconnection, it will be unable to effectively fix the screen, resulting in sliding and displacement, and an inability to effectively position the screen.
[0005] Therefore, a dual-screen movable track device is proposed to address the above problems. Utility Model Content
[0006] To overcome the shortcomings of existing technologies and solve the aforementioned problems, a dual-screen movable track device is proposed.
[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A dual-screen movable track device of this utility model includes a track bar and a limiting block movably sleeved on the inner wall of the track bar, dual screens movably sleeved on the outer surface of the limiting block, a rotating rod movably sleeved on the outer surface of the limiting block, a conch turntable fixedly connected to one end of the rotating rod on the inner wall of the limiting block, a fitting groove provided on the outer surface of the conch turntable, rollers provided on the upper and lower edges of the limiting block, a limiting locking plate fixedly connected to the inner wall of the limiting block on both edges, a pushing plate movably sleeved on the middle position of the limiting locking plate, a notched groove provided on one end of the pushing plate, a soft fitting block movably fitting to the outer surface of the limiting block fixedly connected to the outer surface of one end of the pushing plate, and arrow push blocks movably sleeved on the inner wall of the limiting block on both edges of the conch turntable.
[0008] Preferably, the upper and lower surfaces of the limiting block are provided with slots that can be movably fitted onto the outer surface of the push plate at the edge positions on both sides, and the outer surface of the inclined slot notch can be movably overlapped with the outer surface of the arrow push block.
[0009] Preferably, a fixing plate is fixedly connected to the inner wall of the limiting block and located at the two side edges, and is movably sleeved on the inner wall of the arrow push block. An elastic wire is fixedly connected to the outer surface of the fixing plate and is disposed on the inner wall of the arrow push block.
[0010] Preferably, an elastic wire II is fixedly connected to the outer surface of the limiting snap plate, and the other end of the elastic wire II is fixedly connected to the outer surface of the push plate.
[0011] Preferably, the inner walls of the upper and lower sides of the track bar are provided with sliding grooves that are movably fitted onto the outer surface of the limiting block, and the two sides of the track bar are fixedly connected with buckles.
[0012] Preferably, a snap-fit limiting disc is fixedly connected to the outer surface of the limiting block and is movably attached to the outer surface of the track bar, and a fixing block is fixedly connected to the outer surface of the snap-fit limiting disc.
[0013] Preferably, a snap-fit groove is provided on the outer surface of the fixing block and at the two side edges, and a snap-fit arm is movably sleeved on the inner wall of the snap-fit groove, and the outer surface of the snap-fit arm is movably sleeved on the back of the dual screens.
[0014] The beneficial effects of this utility model are:
[0015] This utility model provides a dual-screen movable track device. Rotating the rotating rod causes the conch turntable at one end of the rotating rod to rotate on the inner wall of the limiting block. Simultaneously, the outer surface of the conch turntable has a gradually thickening surface, so that as the conch turntable rotates, it pushes the arrow push block on the outer surface of the fixed plate horizontally to both sides. When the arrow push block slides, the triangular inclined surface at one end pushes the inclined surface at one end of the push plate up and down, thereby causing the soft adhesive block at one end of the push plate to press and adhere to the inner wall of the slide groove. When the soft adhesive blocks at the four corners of the limiting block can be omnidirectionally positioned on the inner wall of the slide groove, the position of the limiting block is fixed. At the same time, the adhesive groove on the outer surface of the conch turntable presses and positions on the surface of the arrow push block, so that the conch turntable will not rotate due to the external force of the arrow push block. This achieves the effect of omnidirectional positioning by using the four corners of the limiting block.
[0016] This utility model provides a dual-screen movable track device. When movement is required later, the conch turntable is rotated with the rotating rod, causing the surface of the conch turntable to detach from the surface of the arrow push block. At this time, the elastic wire on the outer surface of the fixing plate will pull back the surface of the arrow push block, causing the surface of the arrow push block to fall off one end of the push plate. Then, the elastic wire on the outer surface of the limiting plate will elastically pull back the push plate, causing the soft block on one end of the push plate to fall off the inner wall of the slide groove. This allows the limiting block to slide off the surface of the slide groove and the track, achieving the effect of multi-directional and multi-angle positioning of the surface of the limiting block without the use of screws or servo motors.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] Specific implementation examples are given below.
[0027] Please see Figure 1 - Figure 6 This utility model provides a dual-screen movable track device, including a track bar 11 and a limiting block 12 movably sleeved on the inner wall of the track bar 11, dual screens 13 movably sleeved on the outer surface of the limiting block 12, a rotating rod 124 movably sleeved on the outer surface of the limiting block 12, a conch turntable a1 fixedly connected to one end of the rotating rod 124 and located on the inner wall of the limiting block 12, a fitting groove a2 provided on the outer surface of the conch turntable a1, and the upper and lower edges of the limiting block 12... A roller a4 is provided. A limiting plate a8 is fixedly connected to the inner wall of the limiting block 12 and located at the two side edges. A push plate a10 is movably sleeved at the middle position of the limiting plate a8. A notch with a slanted groove is provided at one end of the push plate a10. A soft block a11 that is movably attached to the outer surface of the limiting block 12 is fixedly connected to the outer surface of the pushing plate a10. An arrow push block a7 is movably sleeved on the inner wall of the limiting block 12 and located at the two side edges of the conch turntable a1.
[0028] During operation, the roller a4 on the inner wall of the limiting block 12 slides on the inner wall of the slide groove 111. When the limiting block 12 moves to the appropriate position, it rotates the rotating rod 124. Simultaneously, the rotating rod 124 drives the conch-shaped turntable a1 at one end of the rotating rod 124 to rotate on the inner wall of the limiting block 12. The gradually varying thickness of the outer surface of the conch-shaped turntable a1 causes it to push the arrow pusher a7 on the outer surface of the fixed plate a5 horizontally to both sides as it rotates. When the arrow pusher a7 slides, the triangular inclined surface at one end pushes the inclined surface at one end of the pushing plate a10 up and down, thus controlling the movement of the limiting block. Under the constraint of the connecting plate a8, the push plate a10 can only move vertically up and down, thereby causing the soft block a11 on one end of the push plate a10 to press and adhere to the inner wall of the slide groove 111. When the soft blocks a11 at the four corners of the limiting block 12 can be positioned in all directions on the inner wall of the slide groove 111, the position of the limiting block 12 is fixed. At the same time, the fitting groove a2 on the outer surface of the conch turntable a1 is pressed and positioned on the surface of the arrow push block a7, so that the conch turntable a1 will not rotate due to the external force of the arrow push block a7, thus achieving the effect of omnidirectional positioning by using the four corners of the limiting block 12.
[0029] Furthermore, such as Figures 1 to 6 As shown, the upper and lower surfaces of the limiting block 12, and the edges of the limiting block 12, have slots a3 that are movably fitted onto the outer surface of the push plate a10. The outer surface of the oblique slot notch is movably overlapped with the outer surface of the arrow push block a7. The inner wall of the limiting block 12, and the edges of the limiting block 12, are fixedly connected to a fixing plate a5 that is movably fitted onto the inner wall of the arrow push block a7. The outer surface of the fixing plate a5 is fixedly connected to an elastic wire a6 that is disposed on the inner wall of the arrow push block a7. The outer surface of the limiting snap plate a8 is fixedly connected to an elastic wire a9. The other end of the elastic wire a9 is fixedly connected to the outer surface of the push plate a10.
[0030] During operation, if movement is required later, the conch turntable a1 is rotated in conjunction with the rotating rod 124, causing the surface of the conch turntable a1 to detach from the surface of the arrow push block a7. At this time, the elastic wire a6 on the outer surface of the fixing plate a5 will pull back the surface of the arrow push block a7, causing the surface of the arrow push block a7 to detach from one end of the push plate a10. Then, the elastic wire a9 on the outer surface of the limiting snap plate a8 will elastically pull back the push plate a10, causing the soft block a11 on one end of the push plate a10 to detach from the inner wall of the slide groove 111. This allows the limiting block 12 to detach and slide on the surfaces of the slide groove 111 and the track 11, achieving the effect of multi-directional and multi-angle positioning of the surface of the limiting block 12 without the use of screws or servo motors.
[0031] Furthermore, such as Figures 1 to 6 As shown, the inner walls of the upper and lower sides of the track bar 11 are provided with sliding grooves 111 that are movably fitted onto the outer surface of the limiting block 12. Locks 112 are fixedly connected to the two sides of the track bar 11. A snap-fit limiting plate 121 that is movably attached to the outer surface of the track bar 11 is fixedly connected to the outer surface of the limiting block 12. A fixing block 122 is fixedly connected to the outer surface of the snap-fit limiting plate 121.
[0032] During operation, as the limiting block 12 moves on the inner wall of the track 11, the locking limiting plate 121 on the outer surface of the limiting block 12 engages with the inner wall of the slide groove 111, thereby increasing the adsorption and firmness between the limiting block 12 and the slide groove 111. This prevents the limiting block 12 from tilting due to the weight of the dual screens 13, thus preventing the limiting block 12 from effectively sliding on the inner wall of the slide groove 111 due to the angle deviation between the limiting block 12 and the slide groove 111.
[0033] Furthermore, such as Figures 1 to 3 As shown, a snap-fit groove 123 is provided on the outer surface of the fixing block 122 and at the two side edges. A snap-fit arm 125 is movably sleeved on the inner wall of the snap-fit groove 123. The outer surface of the snap-fit arm 125 is movably sleeved on the back of the dual screen 13.
[0034] When the limiting block 12 moves to the appropriate position, the rotating rod 124 is rotated to position the limiting block 12, and one end of the latching arm 125 is latched into the inner wall of the latching groove 123. At this time, the latches on the back of the dual screens 13 are then attached to the outer surface of the latching arm 125. At this time, the four corners of the limiting block 12 are all limited to the inner wall of the slide groove 111, and there will be no positional shift or flipping under the pressure of the two external dual screens 13.
[0035] Working principle: The roller a4 on the inner wall of the limiting block 12 slides on the inner wall of the slide groove 111. When the limiting block 12 moves to the appropriate position, it rotates the rotating rod 124. While rotating, the rotating rod 124 drives the conch turntable a1 on one end of the rotating rod 124 to rotate on the inner wall of the limiting block 12. At the same time, the gradually thickened outer surface of the conch turntable a1 causes it to push the arrow push block a7 on the outer surface of the fixed plate a5 horizontally to both sides. When the arrow push block a7 slides, the triangular inclined surface on one end pushes the inclined surface on one end of the push plate a10 up and down. Under the constraint of the snap-fit plate a8, the push plate a10 can only move vertically up and down, thereby causing the soft block a11 on one end of the push plate a10 to press and adhere to the inner wall of the slide groove 111. When the soft blocks a11 at the four corners of the limiting block 12 can be positioned in all directions on the inner wall of the slide groove 111, the position of the limiting block 12 is fixed. At the same time, the fitting groove a2 on the outer surface of the conch turntable a1 is pressed and positioned on the surface of the arrow push block a7, so that the conch turntable a1 will not rotate due to the external force of the arrow push block a7, thus achieving the effect of omnidirectional positioning of the four corners of the limiting block 12.
[0036] If movement is required later, the conch turntable a1 is rotated in conjunction with the rotating rod 124, causing the surface of the conch turntable a1 to detach from the surface of the arrow push block a7. At this time, the elastic wire a6 on the outer surface of the fixing plate a5 will pull back the surface of the arrow push block a7, causing the surface of the arrow push block a7 to detach from one end of the push plate a10. Then, the elastic wire a9 on the outer surface of the limiting snap plate a8 will elastically pull back the push plate a10, causing the soft block a11 on one end of the push plate a10 to detach from the inner wall of the slide groove 111. This allows the limiting block 12 to detach and slide on the surfaces of the slide groove 111 and the track 11, achieving the effect of multi-directional and multi-angle positioning of the surface of the limiting block 12 without the use of screws or servo motors.
[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
