Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] With reference to Figures 1-3The utility model provides a kind of LED arrow guiding light of convertible indicating direction, including base 1 and protection assembly, base 1 is as the support structure of entire guiding light, usually by strong durable material, such as metal or high-strength plastic is made.For the stable placement of guiding light in various environments, base 1 has enough stability.The top of base 1 is fixedly connected with mounting frame 2.Mounting frame 2 is usually made of metal material, with higher strength and stability.Mounting frame 2 provides the position of installation and support for other components of guiding light.The inside of mounting frame 2 is rotatably connected with rotating column 3.Rotating column 3 is usually made of metal material, with higher strength and wear resistance.Rotating column 3 can rotate freely inside mounting frame 2, providing the basis for the rotation of arrow guiding light body 4.The outside of rotating column 3 is fixedly connected with arrow guiding light body 4.Arrow guiding light body 4 is the core component of entire guiding light, which can emit bright LED light to indicate a specific direction.Arrow guiding light body 4 is usually made of high-strength plastic or metal material, with good waterproof, dustproof and shock resistance.The protection assembly is arranged outside arrow guiding light body 4, and the inside of arrow guiding light body 4 is provided with dismounting assembly for quickly dismounting arrow guiding light body 4.The dismounting assembly includes cover plate 5 and two sliding columns 9.Cover plate 5 is usually made of plastic or metal material, with certain strength and sealing property.Cover plate 5 is arranged inside arrow guiding light body 4, which can protect the internal components of arrow guiding light body 4.The outside of arrow guiding light body 4 is provided with two mounting grooves 8.The mounting grooves 8 provide a track for the sliding of sliding column 9.The sliding column 9 is slidingly connected to the inner wall through hole of mounting groove 8.The sliding column 9 is usually made of metal material, with higher strength and wear resistance.The outside of cover plate 5 is fixedly connected with two combination blocks 6.The combination block 6 is usually made of metal material, with higher strength and stability.The inside of combination block 6 is provided with clamping hole 7.The clamping hole 7 cooperates with sliding column 9 to fix cover plate 5.The outside of sliding column 9 is fixedly connected with L-shaped plate 10.The L-shaped plate 10 is usually made of metal material, with higher strength and stability.L-shaped plate 10 facilitates the sliding column 9 to be pushed by operator.The outside of sliding column 9 is sleeved with spring 11.The spring 11 has elasticity and can stretch within a certain range.The one end of spring 11 is fixedly connected with the outside of L-shaped plate 10, and the other end of spring 11 is fixedly connected with the inner wall of mounting groove 8.The spring 11 provides a certain elastic force for sliding column 9, so that sliding column 9 can be tightly inserted into clamping hole 7, and the fixation of cover plate 5 is ensured.The outside of sliding column 9 is slidingly connected with the inside of clamping hole 7, and the outside of combination block 6 is slidingly connected with the inside of mounting groove 8, so that cover plate 5 can be stably installed inside arrow guiding light body 4.

[0025] Specifically, when the arrow direction lamp body 4 needs to be repaired due to failure, the first consideration is to disassemble the cover plate 5. In this process, the protective shell 13 can be removed first, which is usually tightly fitted on the outside of the arrow direction lamp body 4 and plays multiple important roles. On the one hand, it can shield the cover plate 5 and protect it from external environmental factors such as dust, collision, etc. On the other hand, in rainy weather, the protective shell 13 can effectively prevent rainwater from entering the inside of the arrow direction lamp body 4, avoiding damage to the internal circuit elements and LED lamp beads and other key components due to rainwater intrusion, thereby prolonging the service life of the arrow direction lamp and ensuring its stable operation in various weather conditions. When the protective shell 13 is removed, the cover plate 5 is exposed, providing convenience for subsequent maintenance operations. Then, the two L-shaped plates 10 are pushed to drive the sliding column 9 to slide. The design of the L-shaped plate 10 facilitates the operation of the operator and can easily exert force to push the sliding column 9. When one end of the sliding column 9 is pulled out from the inside of the clamping hole 7, the restriction on the combined block 6 is released. This design is very clever and can quickly open the cover plate 5 when maintenance is needed. Compared with the traditional bolt fastening method, this disassembly method has obvious advantages. The traditional bolt fastening method usually requires the use of special tools such as screwdrivers, wrenches, etc., and the operation process is relatively cumbersome, requiring more time and effort. This disassembly method by pushing the L-shaped plate 10 to drive the sliding column 9 saves the assistance of other tools and is more convenient to operate. The operator can quickly complete the disassembly of the cover plate 5 without tools, greatly improving the maintenance efficiency, especially in emergency situations, the arrow direction lamp body 4 can be repaired in time, reducing the time loss and inconvenience caused by failure.

[0026] Referring to Figures 4-5The protection assembly comprises a protection shell 13. The protection shell 13 is usually made of high-strength plastic or metal material, has good waterproof, dustproof and shockproof performance. The protection shell 13 is arranged outside the arrow guiding lamp body 4, which can protect the arrow guiding lamp body 4 from the influence of the external environment. The outer side of the protection shell 13 is in sliding connection with the outer side of the mounting frame 2, which ensures that the protection shell 13 can be stably installed outside the arrow guiding lamp body 4 and can be conveniently removed when needed. The inner side of the protection shell 13 is fixedly connected with two clamping blocks 14. The clamping blocks 14 are usually made of metal material, have high strength and stability. The outer side of the clamping block 14 is fixedly connected with a clamping bead 15. The clamping bead 15 is usually made of elastic material, such as rubber or plastic. The clamping bead 15 cooperates with the assembly groove 12 to fix the protection shell 13. The outer side of the arrow guiding lamp body 4 is provided with two assembly grooves 12. The assembly groove 12 cooperates with the clamping bead 15 to fix the protection shell 13. The clamping bead 15 is located between the assembly groove 12 and the cover plate 5, which ensures that the protection shell 13 can be stably installed outside the arrow guiding lamp body 4 and will not affect the installation and removal of the cover plate 5. The outer side of the rotating column 3 is fixedly connected with a cylindrical gear 16. The cylindrical gear 16 is usually made of metal material, has high strength and wear resistance. The cylindrical gear 16 is located inside the mounting frame 2 and cooperates with the rack plate 19 to realize the rotation of the arrow guiding lamp body 4. The bottom of the mounting frame 2 is provided with an electric push rod 17. The electric push rod 17 is an electric device capable of realizing linear motion, which has high precision and stability. The electric push rod 17 can provide power for the rotation of the arrow guiding lamp body 4. The output end of the electric push rod 17 is fixedly connected with a connecting block 18. The connecting block 18 is usually made of metal material, has high strength and stability. The connecting block 18 provides a mounting position for the rack plate 19. The outer side of the connecting block 18 is fixedly connected with a rack plate 19. The rack plate 19 is usually made of metal material, has high strength and wear resistance. The rack plate 19 cooperates with the cylindrical gear 16 to realize the rotation of the arrow guiding lamp body 4. The top of the rack plate 19 is in meshing connection with the outer side of the cylindrical gear 16, which ensures that the power of the electric push rod 17 can be effectively transmitted to the rotating column 3 to realize the rotation of the arrow guiding lamp body 4.

[0027] Specifically, during the use of the arrow guiding lamp, sometimes it is necessary to change the direction of indication to meet different needs. At this time, the electric push rod 17 plays a key role. The electric push rod 17 drives the connecting block 18 to move, and the connecting block 18 is fixedly connected with the rack plate 19, so the movement of the connecting block 18 will drive the rack plate 19 to move. The rack plate 19 is in meshing connection with the cylindrical gear 16, and when the rack plate 19 moves, it will drive the cylindrical gear 16 to rotate. The cylindrical gear 16 is fixed on the outside of the rotating column 3, so the rotation of the cylindrical gear 16 will transmit the force to the rotating column 3, thereby realizing driving the arrow guiding lamp body 4 to rotate. In this way, the arrow guiding lamp body 4 can flexibly change the direction of indication to adapt to different scenes and needs. For example, in the guidance of traffic intersection, according to the change of traffic flow, the indication direction of the arrow guiding lamp can be adjusted at any time to improve the efficiency and accuracy of traffic guidance. Moreover, the protective shell 13 is sleeved outside the arrow guiding lamp body 4, which has the protection effect mentioned above and also has a certain safety. When the arrow of the protective shell 13 is vertically upward, the mounting frame 2 no longer blocks the protective shell 13, and only at this angle can the protective shell 13 be removed. This design ensures that the protective shell 13 can be firmly installed outside the arrow guiding lamp body 4 during normal use and will not fall off due to accidental circumstances. Only when specific operations such as maintenance or replacement of parts are needed, can the protective shell 13 be removed at the correct angle. This design improves the safety and reliability of the arrow guiding lamp, avoiding the damage of internal components or affecting the normal work of the arrow guiding lamp due to accidental falling of the protective shell 13.

[0028] Working principle: When the arrow guiding lamp body 4 fails and needs to be disassembled for maintenance, the protective shell 13 can be removed first to expose the cover plate 5, and then the two L-shaped plates 10 are pushed to drive the sliding column 9 to slide. When one end of the sliding column 9 is pulled out from the inside of the clamping hole 7, the restriction on the combined block 6 is released, and the cover plate 5 can be removed from the inside of the arrow guiding lamp body 4 at the position of the assembly groove 12. This disassembly method saves the use of other tools compared with traditional bolt fastening, and the operation is more convenient.

[0029] In addition, the electric push rod 17 drives the connecting block 18 to move, and then the rack plate 19 drives the cylindrical gear 16 to rotate, thereby transmitting the force to the rotating column 3 to drive the arrow guiding lamp body 4 to rotate, so that the arrow guiding lamp body 4 can change the direction of indication. Moreover, the protective shell 13 is sleeved outside the arrow guiding lamp body 4 to shield the cover plate 5, and can also prevent rainwater from entering the inside of the arrow guiding lamp body 4 in rainy days. When the arrow of the protective shell 13 is vertically upward, the mounting frame 2 no longer blocks the protective shell 13, and only at this angle can the protective shell 13 be removed, so that the protective shell 13 has better safety.

[0030] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
