Description

Technical Field

[0001] The utility model relates to the technical field of road warning device structures, in particular to a luminous warning device for flooded road surfaces at night. Background Art

[0002] Warning signs convey specific safety warnings through warning text or images. Energy-storage self-luminous warning signs absorb energy from light sources like sunlight and lamps, then re-emit light in dim or no light, making them easier for pedestrians to notice at night. While they are widely used because they don't require additional energy, they still have many problems and drawbacks. Traditional energy-storage self-luminous warning signs are mostly fixed structures that cannot adapt to weather conditions. They remain unchanged in sunny and rainy weather, making their applicability extremely limited.

[0003] If the warning sign is erected completely at the location where warning is required, it may block the road and hinder the passage of people. However, if the warning sign is made into a structure close to the ground to facilitate the passage of people, then in the case of water accumulation at night, its warning range and effect will be extremely limited, and it will not achieve the effect of widespread reminder.

[0017] According to the nighttime flooded road surface luminous warning device provided by the present application, the housing is provided with:

[0018] A guide plate, wherein the guide plate is a plate-shaped structure slidably connected to the bottom of the hollow cavity of the shell, and one end of the guide plate is connected to the third pull rope;

[0019] A support plate, the lower end of which is fixed to the other end of the guide plate, and the upper end of the support plate is provided with a second inclined surface corresponding to the first inclined surface at the end of the second light-emitting plate. When the third pull rope pulls the guide plate toward the center of the shell, the support plate drives the second light-emitting plate to rise through the cooperation of the second inclined surface and the first inclined surface, and when the third pull rope pulls the guide plate away from the center of the shell, the support plate drives the second light-emitting plate to fall through the cooperation of the second inclined surface and the first inclined surface.

[0023] The advantages of the present application are as follows: 1. The warning device of the present application is a movable structure, which can automatically flip according to the water level of the drainage well. When the water level in the drainage well exceeds the first floating plate, it proves that the drainage well has been unable to drain the water in time. Water accumulates on the road surface. The first floating plate can pull the first light-emitting plate to flip to a vertical state. The first light-emitting plate can emit light by itself to provide a warning effect for passers-by. Moreover, when there is no water on the road surface, the first light-emitting plate will flip into the frame and will not cause any obstruction to the road surface, and will not affect the passage of people. The whole device is fully automatically controlled and does not require human operation. The design structure is simple and suitable for large-scale promotion and application.

[0024] 2. The present application has a very simple structure for adjusting the first light-emitting panel. By providing a slide groove in the frame and using the first pull rope to pull the slider to slide in the slide groove, the first light-emitting panel can be switched between the horizontal state and the vertical state. The overall adjustment structure is very simple, and the flip adjustment of the first light-emitting panel is very smooth, with few failures and is not easily affected.

[0025] 3. The present application also provides a reset structure within the frame. The reset structure can drive the first light-emitting panel to flip to a horizontal state after the first light-emitting panel flips to a vertical state and the water on the road subsides, thereby preventing the first light-emitting panel from flipping to a vertical state under normal circumstances and affecting the passage of pedestrians on the road. The reset structure involves few parts and is very simple to operate. It can be automatically operated by the action of the reset spring, making it very convenient to use.

[0026] 4. This application fills the piston cavity with a colored liquid and uses the piston to drive or pump the colored liquid. When the first light-emitting panel is flipped to a vertical position, a colored warning text is displayed on the first light-emitting panel. When the first light-emitting panel is flipped to a horizontal position, the first light-emitting panel returns to its original position. The overall display method is very simple and can achieve a striking warning effect.

[0027] 5. The present application also provides a locking structure on the frame. The locking structure can prevent the first light-emitting panel from flipping to a vertical position when there is no water on the road surface, thereby preventing the first light-emitting panel from malfunctioning. The first light-emitting panel can be stably accommodated in the frame when there is no water on the road surface, and will not be malfunctioned.

[0028] 6. The present application is also provided with a second luminous plate. On the one hand, the second luminous plate can further enhance the warning effect of the entire warning device. On the other hand, the second luminous plate can automatically float up when the water level in the drainage well rises, forming a raised texture structure on the shell, which can enhance the anti-slip effect. At the same time, the raised texture can also self-luminesce, thereby improving the warning effect for pedestrians on the road.

[0029] 7. The present invention provides a very simple method for adjusting the lifting of the second light-emitting panel. By driving the guide plate and the support plate via the third pull rope, the structure composed of the first inclined surface and the second inclined surface can convert the linear motion of the guide plate and the support plate into lifting motion, thereby conveniently controlling the second light-emitting panel. Furthermore, the lifting of the second light-emitting panel is fully automatically controlled based on the water level in the drainage well, while the lifting of the protrusion is completely dependent on the water level in the drainage well.

[0030] 8. The present application sets a guide column in the housing to facilitate the installation of the third pull rope. The third pull rope can simultaneously control multiple guide plates and support plates on both sides, facilitating the lifting and adjustment of the second light-emitting panel, making the lifting and adjustment of the second light-emitting panel smoother and more stable.

[0031] 9. This application sets an elastic member between the guide plate and the guide column. The elastic member is a reset structure. When the water level in the drainage well drops, it can automatically drive the guide plate to move, causing the second light-emitting plate to drop, thereby lowering the protrusion. The overall design is very sophisticated.

[0032] 10. The second light-emitting panel of the present application has a simple structure and is very easy to manufacture, install and use. The combined structure of the sliding plate and the columnar protrusions can be lifted and moved well in the shell.

[0033] The warning device of the present application has a simple structure and is easy to use. The light-emitting panel can be flipped and adjusted according to the water level of the drainage well. It can be flipped to a vertical state when there is water on the road, providing a warning effect for pedestrians passing through flooded roads at night. It can be flipped to a horizontal state under normal circumstances without water accumulation, which does not affect road traffic. The overall structure is simple and suitable for large-scale promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] The present application relates to a luminous warning device for waterlogged roads at night. The warning device of the present application is a self-luminous structure that can automatically emit light when there is no external light source on the road surface at night, providing a luminous warning effect for people passing through the road. At the same time, the warning device of the present application can be adjusted according to the water level of a nearby drainage well. When the drainage well cannot drain the accumulated water in time, that is, when there is water on the road surface, the warning device can be automatically adjusted to flip the luminous structure that was originally in a horizontal state to a vertical state, providing a more eye-catching warning effect for people passing through. When there is no water on the road surface, the luminous structure can be flipped to a horizontal state, which does not affect the passage of pedestrians and does not cause any obstruction. It is very convenient to use.

[0047] Specifically, such as Figures 1 to 7 As shown, a nighttime flooded road surface luminous warning device of the present application includes a frame 1, a first luminous panel 2 and a flip adjustment structure. The frame 1 is a square frame structure fixed to the ground near the drainage well 3. Because the warning device of the present application is controlled by the water level of the nearby drainage well, the frame 1 of the warning device is installed on the ground near the drainage well 3; one end of the first luminous panel 2 is hingedly connected to the frame 1 and can rotate around a horizontal axis. The first luminous panel 2 is a self-luminous plate-shaped structure whose surface displays warning text when flipped to a vertical state. The first luminous panel 2 is a mixture of glass microcrystals and luminescent powder. The structure sintered and formed on a high-temperature resistant pad after being evenly mixed can store light when there is sufficient light during the day and automatically emit light when the light is weak at night, thereby achieving the effect of warning pedestrians. At the same time, the first light-emitting panel 2 is a soft structure and can recover on its own after collision and bending, and is not easily damaged. The flip adjustment structure includes a first floating plate 4 arranged on the top of the drainage well 3. The first floating plate 4 is connected to the first light-emitting panel 2 through a first pull rope 5 and when rainwater in the drainage well 3 overflows the first floating plate 4, the first light-emitting panel 2 is pulled by the first pull rope 5 to flip the first light-emitting panel 2 from a horizontal state to a vertical state.

[0048] When in use, after installing the warning device on the ground near the drainage well 3, the first light-emitting panel 2 is connected to the first floating panel 4 through the first pull rope 5; when there is sufficient light during the day, the first light-emitting panel 2 automatically stores light, and when the light is not obvious at night, the first light-emitting panel 2 automatically emits light to provide a light warning for pedestrians at night; when the water level in the drainage well 3 exceeds the first floating panel 4, the first floating panel 4 is affected by the buoyancy and will pull the first light-emitting panel 2 through the first pull rope 5, flipping the first light-emitting panel 2 that was originally in a horizontal state to a vertical state, providing a more eye-catching warning effect for pedestrians.

[0049] In some embodiments of the present application, the present embodiment further optimizes the above-mentioned flip adjustment structure. Specifically, Figure 3As shown, an arc-shaped slide groove 6 is provided in the frame 1, and a slider 7 that can slide along the slide groove 6 is provided in the slide groove 6. One end of the first light-emitting panel 2 is fixedly connected to the slider 7, one end of the first pull rope 5 is connected to the first floating plate 4, and the other end is connected to the slider 7. When rainwater in the drainage well 3 overflows the first floating plate 4, the slider 7 is pulled by the first pull rope 5 to slide to one side of the slide groove 6 to flip the first light-emitting panel 2 to a vertical state. When the water level in the drainage well 3 is lower than the first floating plate 4, the slider 7 is on the other side of the slide groove 6 to flip the first light-emitting panel 2 to a horizontal state.

[0050] In actual operation, when the water level in the drainage well 3 exceeds the first floating plate 4, the first floating plate 4 is subjected to the buoyancy and will pull the slider 7 connected thereto through the first pull rope 5, and the slider 7 moves to one side of the chute 6. Under the action of the arc chute 6, the first light-emitting panel 2 fixed on the slider 7 will flip from the original horizontal state to the vertical state. Figure 1 The situation shown is that the first light-emitting panel 2 can be turned over in this way.

[0051] In a further embodiment of the present application, the flip adjustment structure is further optimized. Specifically, Figure 3 and 7 As shown, the frame 1 of this embodiment is provided with a reset structure for driving the slider 7 to move to the other side when the water level in the drainage well 3 is lower than the first floating plate 4. The reset structure includes a piston cavity 8 provided in the frame 1, a piston 9 is passed through the piston cavity 8, and a piston rod 10 is connected to the piston 9. A reset spring 11 is provided in the rodless cavity in the piston cavity 8, one end of the reset spring 11 is pressed against the side wall of the piston cavity 8, and the other end is pressed against the side of the piston 9 away from the piston rod 10. The rod body of the piston rod 10 outside the piston cavity 8 is connected to the slider 7 through an elastic pull rope 29. The elastic pull rope 29 and the first pull rope 5 are respectively placed on both sides of the slider 7, and the force direction of the elastic pull rope 29 when driving the first light-emitting panel 2 to flip to a horizontal state is opposite to the force direction of the first pull rope 5 when driving the first light-emitting panel 2 to flip to a vertical state.

[0052] When the water on the road is drained out by the drainage well 3, the water level in the drainage well 3 drops. At this time, the first float plate 4 is no longer in the water, and the first float plate 4 is no longer affected by the buoyancy and drops down under the action of gravity, and no longer applies traction to the slider 7 through the first pull rope 5. At this time, the reset spring 11 drives the piston 9 to move to the side of the piston rod 10, and the piston rod 10 applies traction in the other direction to the slider 7 through the elastic pull rope 29. The force applied by the elastic pull rope 29 to the slider 7 at this time is opposite to the force applied by the first pull rope 5 to the slider 7. Under the action of the elastic pull rope 29, the slider 7 will slide in the slide groove 6 to one side of the slide groove 6, and the first light-emitting panel 2 will flip to the horizontal state, that is, the first light-emitting panel 2 is switched from the vertical state to the horizontal state.

[0053] The reset structure of this embodiment not only plays the role of resetting the first light-emitting panel 2, but also plays the role of displaying warning text on the first light-emitting panel 2. Figure 3 As shown, a warning display structure is provided on the first light-emitting panel 2, and the warning display structure includes an identification flow channel 13 opened on the light-emitting warning side of the first light-emitting panel 2. The identification flow channel 13 is connected with the piston cavity 8 through a channel. The piston cavity 8 is filled with a colored liquid. When the first light-emitting panel 2 is flipped to a vertical state, the colored liquid in the piston cavity 8 is squeezed by the piston 9 through the channel into the identification flow channel 13 to display the warning text corresponding to the identification flow channel 13, and is sucked into the piston cavity 8 when the first light-emitting panel 2 is flipped to a horizontal state.

[0054] The identification channel 13 is a hollow transparent channel structure after the colored liquid is passed into it. The identification channel 13 itself is designed to be a transparent structure of warning text. After the colored liquid is passed into it, a colored text structure can be displayed in the identification channel 13. The identification channel 13 is arranged on the first light-emitting panel 2. When the first light-emitting panel 2 is flipped to a vertical state, the colored liquid will enter the identification channel 13 through the hole under the squeezing action of the piston 9, and form a colored warning text structure with the identification channel 13. Then the first light-emitting panel 2 itself is made of a luminous material, and the light emitted by the first light-emitting panel 2 will shine on the identification channel 13 and the colored liquid, thereby forming a luminous colored text structure on the first light-emitting panel 2, achieving a striking reminder effect.

[0055] Similarly, when the water level in the drainage well 3 drops, the first float 4 is no longer in the water, and the first float 4 drops. Under the action of the reset spring 11, the reset spring 11 drives the piston 9 to move toward the side of the piston rod 10, and the pressure in the rodless cavity of the piston cavity 8 is reduced, which produces a suction effect on the marking channel 13, and the colored liquid in the marking channel 13 will be sucked into the rodless cavity. The marking channel 13 is transformed into a transparent structure again, and the warning text is no longer displayed.

[0056] In the preferred embodiment of the present application, a locking structure is further provided on the frame 1, such as Figure 4 and 5 As shown, the locking structure includes a locking pin 14 and a locking spring 15. The locking pin 14 is a pin-shaped structure provided on the frame 1 at both ends of the slider 7. One end of the locking pin 14 is connected to the frame 1 through the locking spring 15, and the other end is inserted into the locking hole 16 at the end of the slider 7 when the first light-emitting panel 2 is flipped to a horizontal state to limit the movement of the slider 7 in the slide groove 6. The first floating plate 4 is connected to the locking pin 14 through the second pull rope 12 and when rainwater overflows the first floating plate 4, the locking pin 14 is pulled by the second pull rope 12 to disengage the locking pin 14 from the locking hole 16.

[0057] When the first light-emitting panel 2 is in a horizontal state, the locking pin 14 is inserted into the locking hole 16 at the end of the slider 7. Because one end of the locking pin 14 is arranged in the frame 1, and the other end is inserted into the locking hole 16 of the slider 7 under the tension of the locking spring 15, the slider 7 is restricted in the guard groove 6, and the slider 7 cannot move in the slide groove 6, thereby limiting the flipping of the first light-emitting panel 2 and limiting the first light-emitting panel 2 to a horizontal state. This can avoid the false triggering of the first light-emitting panel 2; when the water level in the drainage well 3 rises to the position of the first float plate 4, the first float plate 4 is subjected to the buoyancy and will pull the locking pin 14 through the second pull rope 12. After overcoming the action of the locking spring 15, the locking pin 14 will be pulled out of the locking hole 16. At this time, the slider 7 will not be restricted and the slider 7 can slide freely in the slide groove 6.

[0058] In other embodiments of the present application, a receiving groove is further provided on the frame 1, in which a shell 17, a second light-emitting panel 18 and a lifting and adjusting structure are installed. The shell 17 is a cavity structure fixed on the frame 1 and having a hollow cavity; the second light-emitting panel 18 is provided in the shell 17, and the second light-emitting panel 18 is a self-luminous plate-like structure with a plurality of protrusions 21 provided on the upper end surface. The second light-emitting panel 18 is also a plate-like structure that can automatically store and emit light; the lifting and adjusting structure includes a second floating plate 19 provided at the bottom of the drainage well 3, the second floating plate 19 is connected to the second light-emitting panel 18 by a third pull rope 20 and when rainwater in the drainage well 3 overflows the second floating plate 19, the second light-emitting panel 18 is driven to rise by the third pull rope 20 so that the protrusion 21 passes through the through hole on the shell 17 and extends out of the shell 17 to serve as a luminous warning and anti-slip structure.

[0059] The second light-emitting plate 18 corresponds to the situation where the water level in the drainage well 3 exceeds the second float 19 at the bottom. That is, when the water level in the drainage well 3 exceeds the second float 19, the second float 19 will rise due to the buoyancy of the water. The second float 19 will drive the second light-emitting plate 18 through the third pull rope 20, causing the second light-emitting plate 18 to rise. The protrusion 21 on the second light-emitting plate 18 will pass through the through hole on the shell 17 and be exposed from the shell 17, forming a raised texture structure on the surface of the shell 17, which has a good anti-slip effect. This can facilitate the passage of pedestrians when the road is slippery after rain and avoid slipping. At the same time, because the protrusion 21 itself belongs to the second light-emitting plate 18, the protrusion 21 is also a structure that can store light and emit light. Therefore, a luminous texture structure can be formed on the surface of the shell 17 to prompt passers-by.

[0060] The lifting action of the second light emitting panel 18 of this embodiment is realized by the guide plate 22 and the support plate 23 inside the housing 17. Figure 6 As shown, a guide plate 22 and a support plate 23 are provided in the shell 17. The guide plate 22 is a plate-like structure slidably connected to the bottom of the hollow cavity of the shell 17. One end of the guide plate 22 is connected to the third pull rope 20; the lower end of the support plate 23 is fixed to the other end of the guide plate 22, and the upper end of the support plate 23 is provided with a second inclined surface 25 corresponding to the first inclined surface 24 at the end of the second light-emitting plate 18. When the third pull rope 20 pulls the guide plate 22 to move toward the center of the shell 17, the support plate 23 drives the second light-emitting plate 18 to rise through the cooperation of the second inclined surface 25 and the first inclined surface 24; when the third pull rope 20 pulls the guide plate 22 to move away from the center of the shell 17, the support plate 23 drives the second light-emitting plate 18 to fall through the cooperation of the second inclined surface 25 and the first inclined surface 24.

[0061] The cooperation structure of the first inclined surface 24 and the second inclined surface 25 can convert the linear motion of the support plate 23 and the guide plate 22 into the vertical motion of the second light-emitting panel 18. When the guide plate 22 moves toward the center of the shell 17 under the action of the third pull rope 20, the second light-emitting panel 18 rises under the cooperation of the first inclined surface 24 and the second inclined surface 25; when the guide plate 22 moves toward the side wall of the shell 17, the second light-emitting panel 18 descends under the cooperation of the first inclined surface 24 and the second inclined surface 25.

[0062] Specifically, the guide plate 22 is driven by the third pull rope 20. In order to facilitate the drive adjustment of the pull rope 20, a guide column 26 is provided in the shell 17 in this embodiment. A guide groove 27 for the third pull rope 20 to pass through is provided in the guide column 26. The guide groove 27 includes a vertical first groove whose lower end passes through the lower end of the guide column 26 and a plurality of second grooves that are connected to the upper end of the first groove and arranged in a horizontal direction. The third pull rope 20 passes through the first groove and the second groove from bottom to top and is connected to the guide plate 22.

[0063] After a third pull rope 20 passes through the first groove, it can be divided into multiple pull ropes along multiple parallel second grooves and connected to the guide plates 22. Only by controlling the third pull rope 20, all the guide plates 22 can be synchronously driven to move toward the center of the shell 17. The structure is simpler and the control operation is more convenient. At the same time, because the movement of all the guide plates 22 can be synchronously controlled, under the action of the support plate 23, the vertical movement of the second light-emitting panel 18 can be smoother and more stable, and there will be no tilting problem. The protrusion 21 can better extend from the through hole of the shell 17.

[0064] In addition, a reset structure is provided between the guide post 26 and the guide plate 22, such as Figure 6 As shown, an elastic member 28 is disposed between the guide post 26 and the guide plate 22 to drive the guide plate 22 away from the center of the housing 17 when the water level in the drainage well 3 falls below the second float 19. When the water level in the drainage well 3 drops, the second float 19 is no longer subject to buoyancy, and the pulling force exerted on the second float 19 by the third pull rope 20 decreases until it vanishes. Under the action of the elastic member 28, the guide plate 22 is driven away from the center of the housing 17. With the cooperation of the first inclined surface 24 and the second inclined surface 25, the second light-emitting panel 18 descends, and the protrusion 21 moves downward from the through hole of the housing 17 until the upper end surface of the protrusion 21 is lower than the upper surface of the housing 17.

[0065] The elastic member 28 of this embodiment may be a spring structure or a flexible rubber structure, as long as it can drive the guide plate 22 .

[0066] like Figure 1 、 2As shown in FIG6 , the second light emitting plate 18 of this embodiment includes a plurality of sliding plates arranged at intervals in the horizontal direction and a plurality of columnar protrusions 21 provided on the sliding plates and arranged at intervals in the length direction of the sliding plates.

[0067] In actual use, after the warning device is installed on the ground near the drainage well 3, the first light-emitting panel 2 is connected to the first floating plate 4 through the first pull rope 5, connected to the locking pin 14 through the second pull rope 12, and connected to the guide plate 22 and the second floating plate 19 through the third pull rope 20; when there is sufficient light during the day, the first light-emitting panel 2 and the second light-emitting panel 18 automatically store light, and when the light is not obvious at night, the first light-emitting panel 2 and the second light-emitting panel 18 automatically emit light to provide a light warning for pedestrians at night; when the water level in the drainage well 3 exceeds the second floating plate 18, the second floating plate 18 floats up, and the guide plate 22 is pulled by the third pull rope 20. Under the traction of the third pull rope 20, the guide plate 22 moves toward the center of the shell 17 under the action of the third pull rope 20, and moves to the first inclined surface. Under the cooperation of the first inclined surface 24 and the second inclined surface 25, the second light-emitting plate 18 rises, and the protrusion 21 on the second light-emitting plate 18 passes through the through hole on the shell 17 and is exposed on the upper surface of the shell 17. The upper surface of the shell 17 will give you a raised texture structure, which has the effect of anti-slip and warning; when the water level in the drainage well 3 drops below the second floating plate 18, the second floating plate 19 is no longer affected by the buoyancy, and the traction force of the second floating plate 19 through the third pull rope 20 is reduced to disappear. Under the action of the elastic member 28, the guide plate 22 will be driven to move away from the center of the shell 17. Under the cooperation of the first inclined surface 24 and the second inclined surface 25, the second light-emitting plate 18 descends, and the protrusion 21 moves downward from the through hole of the shell 17 until the upper end surface of the protrusion 21 is lower than the upper surface of the shell 17;

[0068] When the water level in the drainage well 3 exceeds the first floating plate 4, the first floating plate 4 is subjected to the buoyancy and will pull the locking pin 14 through the second pull rope 12. After overcoming the effect of the locking spring 15, the locking pin 14 will be pulled out of the locking hole 16. At this time, the slider 7 will not be restricted, and the slider 7 can slide freely in the slide groove 6. The buoyancy of the first floating plate 4 will pull the slider 7 connected to it through the first pull rope 5. The slider 7 moves to one side of the slide groove 6. Under the action of the arc slide groove 6, the first luminous plate 2 fixed on the slider 7 will flip from its original horizontal state to a vertical state. At the same time, the colored liquid will enter the identification flow channel 13 through the hole under the squeezing action of the piston 9, forming a colored warning text structure with the identification flow channel 13. Then, the first luminous plate 2 itself is a luminous material, and the light emitted by the first luminous plate 2 will shine on the identification flow channel 13 and the colored liquid, thereby forming a luminous colored text structure on the first luminous plate 2, achieving a striking reminder effect.

[0069] When the water level in the drainage well 3 drops from above the first float plate 4 to below the first float plate 4, the first float plate 4 is no longer in the water, and the first float plate 4 drops. Under the action of the return spring 11, the return spring 11 drives the piston 9 to move toward the side of the piston rod 10, and the pressure in the rodless cavity of the piston cavity 8 is reduced, which produces a suction effect on the marking flow channel 13, and the colored liquid in the marking flow channel 13 is sucked into the rodless cavity. The marking flow channel 13 is transformed into a transparent structure again, and the warning text is no longer displayed; since the first float plate 4 is no longer affected by buoyancy, it drops under the action of gravity and no longer applies traction to the slider 7 through the first pull rope 5. At this time, the return spring 11 will drive the piston 9 to the living When the plug rod 10 moves to one side, the piston rod 10 will apply a traction force in the other direction to the slider 7 through the elastic pull rope 29. The force applied by the elastic pull rope 29 to the slider 7 at this time is opposite to the force applied by the first pull rope 5 to the slider 7. Under the action of the elastic pull rope 29, the slider 7 will slide in the slide groove 6 to one side of the slide groove 6, and the first light-emitting panel 2 will flip to a horizontal state, that is, the first light-emitting panel 2 is switched from a vertical state to a horizontal state; when the first light-emitting panel 2 is switched to a horizontal state and the slider 7 slides to be aligned with the locking pin 14, under the action of the locking spring 15, the locking pin 14 will be driven to be inserted into the locking hole, and the slider 7 will be locked again.
