[0016] Compared with the known public technologies, the technical solution provided by the present invention has the following beneficial effects:

[0017] The present invention rotates the top of the lamp panel to install it on both sides of the installation box, and provides a pull-out plate under the lamp panel.

At normal times, the end of the laser projection lamp away from the rotating shaft is always rotated upward and is restricted by a block inside the lamp box. When the limit rod moves downward, the end of the laser projection lamp away from the rotating shaft is squeezed, causing the laser projection lamp to rotate around the rotating shaft. This can change the position of the laser projection lamp projected on the road surface and can adapt to different intersections. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] The present invention will be further described below with reference to the embodiments.

[0039] Pedestrian lights are a type of traffic light, specifically used to indicate when pedestrians can safely cross the road. To facilitate the inspection and maintenance of the electronic components inside the light box, a sealing plate is usually installed on one side of the outer shell. The sealing plate is connected to the outer shell with bolts. However, since the signal light is exposed to the outdoors, the bolts are easily corroded by rain during use, which makes it difficult to maintain the signal light later.

[0040] To this end, an embodiment of the present invention provides an LED traffic light, the purpose of which is at least to rotate the top of the light board 3 and install it on both sides of the installation box 2, and set a pull-out plate 32 under the light board 3, and by controlling the up and down positions of the lifting plate 14, the lower ends of the light boards 3 on both sides are moved closer to or away from the opening of the installation box 2, so that the light board 3 fits tightly on the installation box 2, and the opening and closing of the light board 3 is more conveniently controlled. When the electrical components inside the installation box 2 need to be repaired, the light board 3 can be conveniently opened and closed.

[0041] Example: An LED traffic light, such as Figure 1 - Figure 5 As shown, it includes a base 1, an installation box 2 is fixedly installed on the top of the base 1, and light boards 3 are respectively provided on two sides of the installation box 2 away from each other. A top plate 21 is fixedly installed on the top of the installation box 2, and the light board 3 is rotatably connected to the top plate 21 through a hinge at the top. The upper end of the light board 3 is rotatably connected to the installation box 2, and a signal light 31 is fixedly installed on the light board 3. The end surfaces of the two light boards 3 facing each other are fixedly installed with a pull-out plate 32 for being stuck in the interior of the installation box 2, and a limiting groove 3201 is provided on the pull-out plate 32;

[0042] The lifting plate 14 is fixedly installed with a telescopic rod 13 on the base 1 for driving the lifting plate 14 to move up and down. Two guide shafts 141 are fixedly installed at both ends of the lifting plate 14. When the lifting plate 14 is at the highest point, the guide shaft 141 slides with the limit groove 3201, pulling the two opposite light panels 3 closer to each other and locking the positions of the two light panels 3.

[0043] In the present invention, the top of the lamp panel 3 is rotated and installed on both sides of the installation box 2, and a pull-out plate 32 is provided under the lamp panel 3. When it is necessary to open the interior of the installation box 2 for inspection, the lifting plate 14 is controlled to move downward so that the guide shafts 141 at both ends of the lifting plate 14 slide downward out of the limit groove 3201. At this time, the installation box 2 can be easily opened by rotating the lamp panel 3. During the entire inspection process, there is no need to rotate the bolts. At the same time, the operation of opening the installation box 2 can be completed more efficiently and quickly, and the inspection of the interior of the signal light can be completed more efficiently and quickly.

[0044] Further, if Figure 3 and Figure 5 As shown, it also includes a connecting rod folding frame 4, the side view projection outline of the connecting rod folding frame 4 is a diamond, the connecting rod folding frame 4 is fixedly installed inside the installation box 2, the connecting rod folding frame 4 is used to support the lower ends of the light board 3 away from each other, and a traction wheel 43 is rotatably installed inside the installation box 2, and a connecting rope 41 is provided on the traction wheel 43. The middle part of the connecting rope 41 passes around the traction wheel 43, and the two ends of the connecting rope 41 are respectively connected to the lower end of the connecting rod folding frame 4 and the lifting plate 14, and the connecting rope 41 is used to drive the two sides of the connecting rod folding frame 4 to prop up outward during the descent of the lifting plate 14.

[0045] Among them, by fixing the diamond-shaped connecting rod folding frame 4 inside the installation box 2, after the lamp panels 3 on both sides of the installation box 2 are relatively opened, by pulling the lower end of the connecting rope 41 downward, the middle part of the connecting rod folding frame 4 can be propped up to both sides, so that the two sides of the connecting rod folding frame 4 can be pressed against the lamp panel 3, preventing the lower end of the lamp panel 3 from rotating toward the installation box 2 under the action of gravity, which can make the maintenance personnel more convenient during the work process.

[0046] It should be noted that, when the lifting plate 14 moves downward to release the restriction on the pull-out plate 32, the lifting plate 14 does not pull the connecting rope 41. Only as the lifting plate 14 continues to move downward will it drive one end of the connecting rope 41 to move downward, and only then will it drive the middle part of the connecting rod folding frame 4 to prop up to both sides.

[0047] Further, if Figure 3 and Figure 5 As shown, the end faces of the two lamp boards 3 that are close to each other are each provided with a baffle 33, and the baffle 33 is used to directly contact the connecting rod folding frame 4. The middle relatively bent part of the connecting rod folding frame 4 is provided with an arc plate 42, and the arc plate 42 is used to support the baffle 33 to prop up the lamp board 3.

[0048] Among them, by setting a baffle 33 on the lamp board 3 and setting an arc plate 42 on the connecting rod folding frame 4, the baffle 33 directly contacts the arc plate 42 during the process of the connecting rod folding frame 4 supporting the lamp board 3, thereby preventing the connecting rod folding frame 4 from squeezing the electrical components on the lamp board 3 when it is against the lamp board 3.

[0049] Further, if Figure 6 and Figure 7 As shown, two side panels 22 are provided inside the installation box 2, and the two side panels 22 are respectively located at the two ends of the lifting plate 14. The end surfaces of the two side panels 22 facing each other are provided with a slide groove 2201, and the pull-out plate 32 is fixedly installed with a sliding column 321 for sliding inside the slide groove 2201, and the side panel 22 is used to guide the sliding of the pull-out plate 32.

[0050] Among them, by arranging the side panels 22 inside the installation box 2 and arranging the sliding posts 321 on the pull-out plate 32, the light board 3 can be rotated more stably inside the installation box 2 during the rotation process.

[0051] Further, if Figure 3 、 Figure 4 and Figure 8 As shown, light boxes 11 are fixedly installed on both sides of the installation box 2, and transparent windows are provided on both sides of the light boxes 11. Two laser projection lamps 12 are relatively installed inside each of the light boxes 11, and the ends of the two laser projection lamps 12 that are away from each other are rotatably connected to the light box 11. The laser projection lamps 12 are used to project signal signs onto the ground of the intersection on both sides of the base 1, and the lifting plate 14 is provided with a limit rod 16 for driving the illumination angle of the laser projection lamp 12.

[0052] Among them, by setting light boxes 11 on both sides of the installation box 2 and setting laser projection lights 12 inside the light boxes 11, the projection color of the laser projection lights 12 is synchronized with the signal lights 31. During use, the laser projection lights 12 irradiate the road surface with lights of synchronized colors, which can remind pedestrians who are looking down at their mobile phones to pass through the intersection quickly, and can transmit the intersection signal to the pedestrians who are looking down in time.

[0053] It should be noted that the limiting groove 3201 includes a vertical portion and an inclined portion distributed up and down. The lifting plate 14 will not release the restriction on the pull-out plate 32 during the up and down movement of the vertical portion. When the lifting plate 14 moves up and down at the vertical portion, it can conveniently drive the limiting rod 16 to move up and down, and the projection angle of the laser projection lamp 12 can be adjusted.

[0054] Further, if Figure 9 and Figure 10 As shown, a torsion spring 121 is provided on the outer side of the rotating shaft 122 that is rotatably connected to the light box 11 for each of the laser projection lamps 12. The torsion spring 121 is used to drive the end of the laser projection lamp 12 away from the rotating shaft 122 to rotate upward. A block 23 for limiting the rotation angle of the laser projection lamp 12 is fixedly installed on the light box 11. Each of the limit rods 16 is located above the two relatively installed laser projection lamps 12. During the downward movement of the limit rods 16, the opposite ends of the two laser projection lamps 12 are driven to rotate downward.

[0055] Among them, by setting a rotating shaft 122 on the laser projection lamp 12 and setting a torsion spring 121 on the outside of the rotating shaft 122 to drive the laser projection lamp 12 to rotate, the end of the laser projection lamp 12 away from the rotating shaft 122 is always rotated upward at normal times and is restricted by the block 23 inside the light box 11. When the limit rod 16 moves downward, it squeezes the end of the laser projection lamp 12 away from the rotating shaft 122, so that the laser projection lamp 12 rotates around the rotating shaft 122 as the axis, so that the position of the laser projection lamp 12 projected on the road surface can be changed, and it can adapt to different intersections.

[0056] In addition, as the two relatively installed laser projection lamps 12 rotate downward relative to each other, the distance between the two laser projection lamps 12 gradually increases. When the distance between the two relatively installed laser projection lamps 12 increases to a certain extent, the limit rod 16 passes through the two relatively installed laser projection lamps 12, and the two laser projection lamps 12 rotate upward and reset under the drive of the torsion spring 121.

[0057] Further, if Figure 6 and Figure 7 As shown, the end surface of the lifting plate 14 facing the lamp board 3 is fixedly installed with a connecting frame 15, the limiting rod 16 is fixedly installed on the connecting frame 15, one end of the connecting rope 41 is connected to the connecting frame 15, the limiting rod 16 is fixedly installed on the side of the connecting frame 15, and the width of the connecting frame 15 is smaller than the width of the inner wall of the base 1.

[0058] Further, if Figure 4 and Figure 8 As shown, the outer side of the limiting rod 16 is covered with a hard rubber sleeve, the side view projection outline of the hard rubber sleeve is a triangle, the bottom of the hard rubber sleeve is hollow, and a notch 1601 is provided on the side of the hard rubber sleeve.

[0059] Among them, by arranging a hard rubber sleeve on the outer side of the limit rod 16, and setting the hard rubber sleeve into a triangle, when the limit rod 16 is located above the laser projection lamp 12 and moves downward (when the interior of the installation box 2 needs to be inspected and the connecting rod folding frame 4 is used for support), the two sides of the triangular hard rubber sleeve can be against the top of the laser projection lamp 12, driving the two laser projection lamps 12 to rotate downward relative to each other. When the limit rod 16 is located below the two laser projection lamps 12 and moves upward (after the staff has completed the inspection of the interior of the installation box 2), the upper end of the hard rubber sleeve on the limit rod 16 will pass between the two laser projection lamps 12. At this time, as the limit rod 16 continues to move upward, the two sides of the hard rubber sleeve will be squeezed by the two laser projection lamps 12, causing the two sides of the hard rubber sleeve to undergo elastic deformation toward the middle, so that the hard rubber sleeve can smoothly pass between the two laser projection lamps 12 and move above the two laser projection lamps 12.

[0060] Working principle: By arranging a telescopic rod 13 on the base 1 and a lifting plate 14 on the telescopic rod 13, the locking of the lamp board 3 can be controlled by controlling the up and down positions of the lifting plate 14. In addition, when the lifting plate 14 moves up and down at the vertical part of the limit groove 3201, the illumination angle of the laser projection lamp 12 can be controlled; in addition, when the locking of the lamp board 3 is released to inspect the inside of the installation box 2, the lifting plate 14 can continue to be driven downward, and when the lifting plate 14 descends, it drives the connecting rope 41 to move downward, so that the connecting rope 41 drives the two sides of the connecting rod folding frame 4 to support the two lamp boards 3 outward, so that the two lamp boards 3 are maintained at an open angle.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
