Description

Technical Field

[0001] This invention belongs to the field of electronic display technology, specifically referring to a method for quickly installing electronic display screens on subway platform screen doors. Background Technology

[0002] As intuitive human-computer interaction devices, electronic displays are used in all aspects of production and life. With the technological innovation of automobiles, the application of electronic displays in automobiles is becoming more and more widespread, such as navigation systems, dashcams, and vehicle rearview mirrors with electronic displays.

[0003] The installation of electronic displays in subway stations currently faces common problems. In subway stations, a large number of waiting people can affect the transmission of information. Existing electronic display devices are not conducive to enhancing noise reduction. At the same time, when electronic displays are fixedly installed, their detachability is affected. Therefore, the ease of installation must be taken into consideration. Summary of the Invention

[0004] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a quick-installation electronic display screen for subway platform screen doors. The symmetrically arranged rotating extension plates rotate in opposite directions, causing the torsion springs on both sides to twist in opposite directions, providing a fixing effect in the horizontal direction. Simultaneously, when the fixing rod penetrates the through-hole and enters the inner rod, the elastic inner plate provides a restoring force. This restoring force, along with the restoring force of the supporting spring, provides a fixing effect in the vertical direction. Furthermore, the sliding wheel, which initially provides temporary fixing and limiting, offers mobility. During the fixing phase, it drives the triangular connector to slide upwards and engage with the embedded auxiliary cavity, achieving absolute control and fixing, eliminating the mobility effect, and providing better stability.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a quick-installation electronic display screen for subway platform screen doors, including a sliding snap-fit ​​embedded sound insulation component, an indirect sliding fixed base component, and a supplementary snap-fit ​​base. The sliding snap-fit ​​embedded sound insulation component is slidably mounted on the indirect sliding fixed base component, and the supplementary snap-fit ​​base is movably mounted on both ends of the indirect sliding fixed base component.

[0006] Furthermore, the sliding snap-fit ​​embedded sound insulation component includes a sound insulation plate, a two-way auxiliary plate, and an embedded auxiliary cavity. The sound insulation plate is disposed on the outer upper wall of the embedded auxiliary cavity, and the two-way auxiliary plates are disposed in pairs on the outer side wall of the sound insulation plate. The embedded auxiliary cavity is hollow, and a torsion snap-fit ​​embedding mechanism and a compression snap-fit ​​rod mechanism are provided on the bottom wall of the embedded auxiliary cavity. The torsion snap-fit ​​embedding mechanism consists of a rotating shaft, a rotating extension plate, and a plate. One end of the rotating shaft is rotatably snap-fitted onto the outer side of the embedded auxiliary cavity. On the bottom wall, one end of the rotating extension plate is located on the other end of the rotating shaft, and the insert plate is located on the other end of the rotating extension plate. A torsion spring is provided on one end of the rotating shaft. The compression-type locking rod mechanism consists of a through hole, an inner rod, and an elastic inner plate. The through hole is located on the bottom wall of the embedded auxiliary cavity, and the lower end of the inner rod is located on the inner bottom wall of the embedded auxiliary cavity. The inner rod matches the through hole, and the inner rod is a hollow cavity with an open lower end. The elastic inner plates are arranged in a ring array on the inner side of the inner rod. On the wall; initially, the sliding snap-fit ​​embedded sound insulation component can be slidably embedded in the indirect sliding fixed base component. Since the indirect sliding fixed base component is slidable, the user can transport the device through the indirect sliding fixed base component. When it moves to the designated position, the slidable indirect sliding fixed base component is controlled to become fixed, and the sliding snap-fit ​​embedded sound insulation component is moved to both sides so that the center line of the sliding snap-fit ​​embedded sound insulation component coincides with the side wall of the indirect sliding fixed base component. The extra part of the sliding snap-fit ​​embedded sound insulation component is fixedly installed below it with a supplementary snap-fit ​​base and connected to the indirect sliding fixed base component. At the same time, the sliding snap-fit ​​embedded sound insulation component is pressed downward, so that the internal rotating extension plate and the insert plate are snapped into the indirect sliding fixed base component. At the same time, the corresponding component of the indirect sliding fixed base component is snapped into the inner rod, and fixed in both directions at the same time. The elastic inner plate in the inner rod is squeezed and expands outward, and its restoring force will play a fixing role.

[0007] The twisting engagement mechanism and the squeezing engagement rod mechanism are arranged alternately.

[0008] Further, the indirect sliding fixed base assembly includes a fixed base, a locking groove, a protruding plate, a rotating extension groove, a recessed groove, and a fixing rod. The fixed base is a hollow cavity with an open top. The locking grooves are arranged in pairs on the inner sidewall of the fixed base and match the recessed plate. The protruding plates are arranged in pairs on the inner sidewall of the fixed base. One end of the rotating extension groove is located on the outer bottom wall of the locking groove, and the recessed groove is located on the other end of the rotating extension groove. The rotating extension groove is located on the protruding plate, and the recessed groove is located on the protruding plate. The fixing rod is located on the outer sidewall of the protruding plate and matches the through hole. Initially, the sliding locking is embedded. The sound insulation component slides on the fixed base, with the panel in the locking groove. When the user applies downward pressure on the sound insulation panel, the connected rotating extension plate moves downward and rotates until the panel automatically engages into the locking groove. During this process, the rotating extension plate rotates on both sides, and the torsion spring connected to it is compressed and twisted. The rotating extension plates on both sides rotate in opposite directions, and the torsion springs on both sides twist in opposite directions, so the resulting restoring forces are opposite and have a fixing effect in the horizontal direction. At the same time, the fixing rod breaks through the through hole and enters the inner rod, compressing the elastic inner plate. The restoring force of the elastic inner plate has a fixing effect.

[0009] Furthermore, the outer bottom wall of the embedded auxiliary cavity is provided with a sliding groove, and the inner bottom wall of the fixed base is provided with a support spring. The support spring is provided with a snap-fit ​​sliding plate, which is located in the sliding groove. When the fixed rod breaks through the through hole and enters the inner rod, the elastic inner plate will provide a restoring force. This restoring force cancels each other out in the horizontal direction, and at the same time, the restoring force is downward in the vertical direction. When the user applies downward force to press the sound insulation board, it will drive the snap-fit ​​sliding plate to slide downward. At this time, the support spring is compressed, and the direction of the restoring force of the support spring is upward, which plays a fixing role in the vertical direction.

[0010] Furthermore, the fixed base is provided with a pair of movable sliding components. Each movable sliding component includes an H-shaped connecting groove, a connecting rod, and a sliding mechanism. The H-shaped connecting groove is located on the side wall of the fixed base. The connecting rod is slidably disposed within the H-shaped connecting groove. The sliding mechanism is provided in pairs at both ends of the connecting rod. The sliding mechanism consists of a sliding vertical rod, a triangular connector, and a torsion spring. The sliding vertical rod is slidably disposed within the H-shaped connecting groove and connected to the connecting rod. A rotating rod is rotatably disposed on the upper end of the sliding vertical rod. The triangular connector is disposed on the rotating rod, and the torsion spring is disposed on the rotating rod. A sliding wheel is disposed on the lower end of the sliding vertical rod. A control gear is rotatably disposed on the fixed base, meshing with the connecting rod. A pair of driven connecting plates are provided at both ends of the snap-fit ​​sliding plate. A pair of driven connecting grooves are provided on the inner side wall of the fixed base. The control gear is set through the driven connecting groove; initially, the sliding wheel protrudes from the outer bottom wall of the fixed base. The user can control the movement of this device through the sliding wheel. Under the action of the torsion spring, the triangular connectors at the four corners will temporarily play a fixing and limiting role. When the displacement reaches the designated position, when the sliding engagement of the embedded sound insulation component is moved to both sides, it will simultaneously drive the triangular connector to rotate along the direction of the rotating rod. The non-sliding engagement of the embedded sound insulation component will play an absolute limiting role. When the user applies downward force to press the sound insulation plate, it will drive the snap-fit ​​sliding plate to slide downward. At this time, the driven connecting plate will slide downward in the driven connecting groove until it meshes with the control gear and drives the connecting rod to slide upward. The connecting rod drives the sliding mechanism to slide upward, which means it drives the triangular connector to slide upward and engage in the embedded auxiliary cavity. The triangular connector engaged in the embedded auxiliary cavity will play an absolute control role.

[0011] Furthermore, a triangular embedding cavity is provided on the outer bottom wall of the embedded auxiliary cavity, and the triangular embedding cavity matches the triangular connector.

[0012] Furthermore, a triangular connecting cavity is provided through the side plate of the embedded auxiliary cavity, and a telescopic rod is provided on the bottom wall of the bidirectional auxiliary plate. The telescopic rod is provided through the triangular connecting cavity, and a fixed connecting groove is provided on the bottom wall of the fixed base. After fixing, the telescopic rod is controlled to extend, so that it passes through the triangular connecting cavity and the fixed connecting groove and contacts the ground, and moves downward so that the telescopic rod is embedded in the ground for fixing.

[0013] Furthermore, the sound insulation board is provided with sound-absorbing cotton, and the inner side wall of the sound insulation board is provided with sound insulation grooves; noise first enters the interior through the outermost sound insulation board, comes into contact with the sound-absorbing cotton, and transmits vibrations to the sound insulation grooves through the sound-absorbing cotton. The air gap between the sound insulation grooves and the sound-absorbing cotton absorbs the noise vibration energy, and then gradually bounces back through the four sides of the sound insulation grooves, so that the noise vibration energy is absorbed multiple times.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows:

[0015] (1) The rotating extension plates arranged on both sides rotate in opposite directions, causing the torsion springs on both sides to twist in opposite directions. Therefore, the restoring forces generated are opposite and have a fixing effect in the horizontal direction. At the same time, when the fixing rod breaks through the through hole and enters the inner rod, the elastic inner plate inside will provide a restoring force. The restoring forces cancel each other out in the horizontal direction. At the same time, the restoring force is downward in the vertical direction. When the user applies downward force to press the sound insulation plate, it will drive the snap-fit ​​sliding plate to slide downward. At this time, the support spring is compressed. The direction of the restoring force of the support spring is upward and has a fixing effect in the vertical direction.

[0016] (2) Initially, the sliding wheel protrudes from the outer bottom wall of the fixed base. The user can control the movement of this device through the sliding wheel. Under the action of the torsion spring, the triangular connectors at the four corners will temporarily play a role in fixing and limiting. However, when the connecting rod drives the triangular connector to slide upward and engages in the embedded auxiliary cavity, the triangular connector engaged in the embedded auxiliary cavity will play an absolute control and fixing effect.

[0017] (3) Initially, the sliding wheel provides a movable function for the fixed base. After entering the H-shaped connecting groove, the movable function of the sliding wheel is completely lost, and it has better stability.

[0018] (4) After the fixing is completed, control the extension rod to extend, pass through the triangular connecting cavity and the fixed connecting groove in sequence, and contact the ground to embed it into the ground for fixing;

[0019] (5) After installation, the noise first comes into contact with the sound-absorbing cotton and transmits the vibration to the sound insulation groove through the sound-absorbing cotton. The air gap between the sound insulation groove and the sound-absorbing cotton absorbs the noise vibration energy and then bounces back through the four sides of the sound insulation groove in turn, so the noise vibration energy is absorbed multiple times.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0039] like Figures 1-15 As shown, the present invention provides a quick-installation electronic display screen for subway platform screen doors, including a sliding snap-fit ​​embedded sound insulation component 1, an indirect sliding fixed base component 2, and a supplementary snap-fit ​​base 3. The sliding snap-fit ​​embedded sound insulation component 1 is slidably attached to the indirect sliding fixed base component 2, and the supplementary snap-fit ​​base 3 is movably attached to both ends of the indirect sliding fixed base component 2.

[0040] The sliding snap-fit ​​embedded sound insulation component 1 includes a sound insulation plate 4, a two-way auxiliary plate 5, and an embedded auxiliary cavity 6. The sound insulation plate 4 is disposed on the outer upper wall of the embedded auxiliary cavity 6, and the two-way auxiliary plates 5 are disposed in pairs on the outer side wall of the sound insulation plate 4. The embedded auxiliary cavity 6 is hollow. The bottom wall of the embedded auxiliary cavity 6 is provided with a torsion snap-fit ​​embedding mechanism 7 and a compression snap-fit ​​rod mechanism 42. The torsion snap-fit ​​embedding mechanism 7 is composed of a rotating shaft 8, a rotating extension plate 9, and a panel 14. One end of the rotating shaft 8 is rotatably snapped onto the outer bottom wall of the embedded auxiliary cavity 6, one end of the rotating extension plate 9 is disposed on the other end of the rotating shaft 8, and the panel 14 is disposed on the other end of the rotating extension plate 9. A torsion spring 10 is provided on one end of the rotating shaft 8. The compression-type locking rod mechanism 42 consists of a through hole 11, an inner rod 12, and an elastic inner plate 13. The through hole 11 is located on the bottom wall of the embedded auxiliary cavity 6. The lower end of the inner rod 12 is located on the inner bottom wall of the embedded auxiliary cavity 6. The inner rod 12 matches the through hole 11. The inner rod 12 is a hollow cavity with an open lower end. The elastic inner plate 13 is arranged in a ring array on the inner side wall of the inner rod 12. The sound insulation plate 4 is provided with sound-absorbing cotton 40. The inner side wall of the sound insulation plate 4 is provided with sound insulation grooves 41. The torsion-type locking embedding mechanism 7 and the compression-type locking rod mechanism 42 are arranged alternately. Initially, the sliding locking embedding... The sound insulation component 1 is slidably embedded in the indirect sliding fixed base component 2. Since the indirect sliding fixed base component 2 is slidable, the user can transport the device via it. When the device reaches a designated position, the user controls the slidable indirect sliding fixed base component 2 to become fixed, while simultaneously moving the sliding snap-fit ​​embedded sound insulation component 1 to both sides, so that the center line of the sliding snap-fit ​​embedded sound insulation component 1 coincides with the side wall of the indirect sliding fixed base component 2. The excess portion of the sliding snap-fit ​​embedded sound insulation component 1 is then fixedly installed below it with a supplementary snap-fit ​​base 3, connecting it to the indirect sliding fixed base component 2. Simultaneously, downward pressure is applied. The sliding snap-fit ​​embedded sound insulation component 1 allows its internal rotating extension plate 9 and insert plate 14 to snap into the indirect sliding fixed base component 2. At the same time, the corresponding component of the indirect sliding fixed base component 2 snaps into the inner rod 12, fixing it in both directions. The elastic inner plate 13 inside the inner rod 12 is compressed and expands outward, and its restoring force plays a fixing role. After installation, noise first enters the interior through the outermost sound insulation plate 4 and comes into contact with the sound-absorbing cotton 40. The vibration is transmitted to the sound insulation groove 41 through the sound-absorbing cotton 40. The air gap between the sound insulation groove 41 and the sound-absorbing cotton 40 absorbs the noise vibration energy, and then it gradually rebounds through the four sides of the sound insulation groove 41. The noise vibration energy is absorbed multiple times.

[0041] The indirect sliding fixed base assembly 2 includes a fixed base 15, a locking groove 16, a protruding plate 17, a rotating extension groove 18, a recessed groove 19, and a fixing rod 20. The fixed base 15 is a hollow cavity with an open top. The locking grooves 16 are arranged in pairs on the inner sidewall of the fixed base 15, and the locking grooves 16 match the recessed plates 14. The protruding plates 17 are arranged in pairs on the inner sidewall of the fixed base 15. One end of the rotating extension groove 18 is located on the outer bottom wall of the locking groove 16, and the recessed groove 19 is located on the other end of the rotating extension groove 18. The rotating extension groove 18 is located on the protruding plate 17, and the recessed groove 19 is located on the protruding plate 17. The fixing rod 20 is located on the outer sidewall of the protruding plate 17, and the fixing rod 20 matches the through hole 11. Initially, The sliding snap-fit ​​embedded sound insulation component 1 slides on the fixed base 15. At this time, the insert 14 is in the engagement groove 16. When the user applies downward force to press the sound insulation plate 4, the connected rotating extension plate 9 moves downward and rotates until the insert 14 automatically engages into the groove 19. At this time, the rotating extension plate 9 is in the rotating extension groove 18. During this process, the rotating shafts 8 on both sides will rotate, and the torsion springs 10 connected to them will be squeezed and twisted. The rotating extension plates 9 on both sides rotate in opposite directions, and the torsion springs 10 on both sides twist in opposite directions. Therefore, the restoring force they generate is opposite and has a fixing effect in the horizontal direction. At the same time, the fixing rod 20 breaks through the through hole 11 and enters the inner rod 12 to squeeze the elastic inner plate 13. The restoring force of the elastic inner plate 13 has a fixing effect.

[0042] The outer bottom wall of the embedded auxiliary cavity 6 is provided with a sliding groove 21, and the inner bottom wall of the fixed base 15 is provided with a support spring 22. The support spring 22 is provided with a snap-fit ​​sliding plate 23, which is located in the sliding groove 21. When the fixed rod 20 breaks through the through hole 11 and enters the inner rod 12, the elastic inner plate 13 will provide a restoring force. The restoring forces cancel each other out in the horizontal direction, and the restoring force is downward in the vertical direction. When the user applies downward force to press the sound insulation plate 4, it will drive the snap-fit ​​sliding plate 23 to slide downward. At this time, the support spring 22 is compressed, and the direction of the restoring force of the support spring 22 is upward, which plays a fixing role in the vertical direction.

[0043] The fixed base 15 is provided with a pair of movable sliding components 24. Each movable sliding component 24 includes an H-shaped connecting groove 25, a connecting rod 26, and a sliding mechanism 27. The H-shaped connecting groove 25 is located on the side wall of the fixed base 15. The connecting rod 26 is slidably disposed within the H-shaped connecting groove 25. The sliding mechanism 27 is provided in pairs at both ends of the connecting rod 26. Each sliding mechanism 27 consists of a sliding vertical rod 28, a triangular connecting piece 29, and a torsion spring 20. The sliding vertical rod 28 is slidably disposed within the H-shaped connecting groove 25. Within 5, the sliding vertical rod 28 is connected to the connecting rod 26. A rotating rod 31 is rotatably mounted on the upper end of the sliding vertical rod 28. The triangular connecting piece 29 is mounted on the rotating rod 31. The torsion spring 30 is mounted on the rotating rod 31. A sliding wheel 32 is mounted on the lower end of the sliding vertical rod 28. A control gear 33 is rotatably mounted on the fixed base 15. The control gear 33 meshes with the connecting rod 26. A pair of driven connecting plates 34 are mounted on both ends of the snap-fit ​​sliding plate 23. A pair of driven connecting plates 34 are mounted on the inner sidewall of the fixed base 15. A driven connecting groove 35 is provided, through which the control gear 33 passes. Initially, the sliding wheel 32 protrudes from the outer bottom wall of the fixed base 15. The user can control the movement of the device through the sliding wheel 32. Under the action of the torsion spring 30, the triangular connectors 29 at the four corners will temporarily play a fixing and limiting role. When the displacement reaches the designated position, when the device moves to both sides to slide and engage the embedded sound insulation component 1, it will simultaneously drive the triangular connector 29 to rotate along the direction of the rotating rod 31. The non-sliding engagement of the embedded sound insulation component 1 will provide absolute restriction. When the user applies downward force to press the sound insulation plate 4, it will drive the engaging slide plate 23 to slide downward. At this time, the driven connecting plate 34 will slide downward in the driven connecting groove 35 until it meshes with the control gear 33 and drives the connecting rod 26 to slide upward. The connecting rod 26 drives the sliding mechanism 27 to slide upward, which means it drives the triangular connector 29 to slide upward and engage in the embedded auxiliary cavity 6. The triangular connector 29 engaged in the embedded auxiliary cavity 6 will provide absolute control.

[0044] The outer bottom wall of the embedded auxiliary cavity 6 is provided with a triangular embedded cavity 36, which matches the triangular connector 29. A triangular connecting cavity 37 is provided through the side plate of the embedded auxiliary cavity 6. A telescopic rod 38 is provided on the bottom wall of the bidirectional auxiliary plate 5, which is provided through the triangular connecting cavity 37. A fixed connecting groove 39 is provided on the bottom wall of the fixed base 15. After fixing, the telescopic rod 38 is controlled to extend, so that it passes through the triangular connecting cavity 37 and the fixed connecting groove 39 and contacts the ground, and moves downward so that the telescopic rod 38 is embedded in the ground for fixing.

[0045] In practical use, in the initial stage, the sliding snap-fit ​​embedded sound insulation component 1 can be slidably embedded in the indirect sliding fixed base component 2. At this time, the panel 14 is in the engagement groove 16. Since the sliding wheel 32 protrudes from the outer bottom wall of the fixed base 15, the user can control the movement of this device through the sliding wheel 32. Under the action of the torsion spring 30, the triangular connectors 29 at the four corners will temporarily play a fixing and limiting role. The user can transport this device through the sliding wheel 32. When it moves to the designated position in the subway station, the embedded auxiliary cavity 6 is moved to both sides so that the center line of the embedded auxiliary cavity 6 coincides with the side wall of the fixed base 15. The extra part of the embedded auxiliary cavity 6 is fixedly installed below it with the supplementary snap-fit ​​base 3, and the supplementary snap-fit ​​base 3 is connected to the fixed base 15. At the same time, the user applies downward force to press the sound insulation plate 4, and the rotating extension plate 9 connected to it moves downward and rotates until... The panel 14 automatically engages into the groove 19. At this time, the rotating extension plate 9 is in the rotating extension groove 18. During this process, the rotating shafts 8 on both sides will rotate, and the torsion springs 10 connected to them will be squeezed and twisted. The rotating extension plates 9 on both sides rotate in opposite directions, and the torsion springs 10 on both sides twist in opposite directions. Therefore, the restoring forces generated are opposite and have a fixing effect in the horizontal direction. At the same time, the fixing rod 20 breaks through the through hole 11 and enters the inner rod 12 to squeeze the elastic inner plate 13. The restoring force of the elastic inner plate 13 has a fixing effect. The elastic inner plate 13 will provide a restoring force, which cancels each other in the horizontal direction. At the same time, the restoring force is downward in the vertical direction. When the user applies downward force to press the sound insulation panel 4, it will drive the snap-fit ​​sliding plate 23 to slide downward. At this time, the support spring 22 is squeezed. The restoring force of the support spring 22 is upward and has a fixing effect in the vertical direction.

[0046] When the user presses down on the sound insulation plate 4, it simultaneously causes the snap-fit ​​sliding plate 23 to slide downwards. At this time, the driven connecting plate 34 slides downwards in the driven connecting groove 35 until it meshes with the control gear 33, and drives the connecting rod 26 to slide upwards. The connecting rod 26 drives the sliding mechanism 27 to slide upwards, which in turn drives the triangular connector 29 to slide upwards and snap into the embedded auxiliary cavity 6. The triangular connector 29 snapped into the embedded auxiliary cavity 6 plays an absolute control role. During this process, the sliding wheel 32 moves upwards and enters the H-shaped connecting groove 25. The sliding wheel 32 no longer provides a movable function for the fixed base 15. After pressing, the control telescopic rod 38 extends, allowing it to pass through the triangular connecting cavity 37 and the fixed connecting groove 39 and contact the ground, moving downwards so that the telescopic rod 38 is embedded in the ground for final fixation.

[0047] After installation, noise first enters the interior through the outermost sound insulation panel 4, comes into contact with the sound-absorbing cotton 40, and transmits vibrations to the sound insulation groove 41 through the sound-absorbing cotton 40. The air gap between the sound insulation groove 41 and the sound-absorbing cotton 40 absorbs the noise vibration energy, and then gradually bounces back through the four sides of the sound insulation groove 41. The noise vibration energy is absorbed and blocked multiple times.
