Description

Technical Field

[0001] This utility model relates to the field of traffic signal device technology, and in particular to a modular combined traffic signal device. Background Technology

[0002] Traffic signal devices are used to direct road traffic flow and control the passage of vehicles and pedestrians. They guide traffic through various signal lights, sounds, or signs to ensure traffic order and safety. They play a vital role in various traffic situations, effectively reducing traffic accidents, alleviating traffic congestion, and improving traffic efficiency.

[0003] Traditional traffic signal systems typically consist of traffic lights, a controller, a power supply, a support frame, and connecting wiring. Traffic lights use three colors—red, yellow, and green—to indicate different traffic signals. The controller controls and switches the traffic lights, while the support frame holds the lights in place, ensuring stable operation. The power supply provides a stable power source to ensure the system functions correctly.

[0004] The main problem with traditional traffic signal devices, which cannot be adjusted in height, lies in their fixed installation method and structural design limitations. Traffic lights are typically installed at a fixed height, unable to be flexibly adjusted according to traffic demand and terrain changes. This fixed height limits the visibility of traffic lights on certain road sections or at complex intersections, making it difficult for drivers to clearly see the signals and affecting traffic safety. The inability to adjust the height also results in poor adaptability of traffic lights to different drivers, pedestrians, and traffic flows, thus impacting traffic flow and safety. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a modular combined traffic signal device, which aims to improve the problem that traditional traffic signal devices cannot adjust their height and have poor adaptability to different drivers, pedestrians and different traffic flows, thus affecting traffic flow and safety.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a modular combined traffic signal device, including a support column, a slip ring slidably connected to the outer wall of the support column, a signal light stand provided on the side wall of the slip ring, and an adjustment component provided on the side wall of the support column;

[0007] The adjustment assembly includes a side platform, the side wall of which is fixedly connected to the side wall of the support column. A rack is fixedly connected to the side wall of the slip ring. An electric motor is fixedly connected inside the side platform. A gear is fixedly connected to the output end of the electric motor. The gear meshes with the rack. A ratchet is fixedly connected to the side wall of the gear. A pawl is rotatably connected to the outer wall of the side platform. The ratchet meshes with the pawl. A limit assembly is provided on the side wall of the signal light stand.

[0008] As a further description of the above technical solution:

[0009] The limiting component includes multiple inner shafts, one end of which is fixedly connected to the side wall of the signal light stand.

[0010] As a further description of the above technical solution:

[0011] Each inner shaft outer wall is fixedly connected to a limit ring, and the slip ring sidewall is fixedly connected to multiple side plates.

[0012] As a further description of the above technical solution:

[0013] Each of the side plates has multiple fixing plates fixedly connected to its upper surface, and the multiple fixing plates are fixedly connected to a fixing shaft.

[0014] As a further description of the above technical solution:

[0015] A clamping plate one is rotatably connected to the outer wall of the fixed shaft, and a clamping plate two is rotatably connected to the outer wall of the fixed shaft.

[0016] As a further description of the above technical solution:

[0017] Both the first clamping plate and the second clamping plate are fixedly connected to connecting plates on their side walls, and each connecting plate is provided with a spring at its bottom.

[0018] As a further description of the above technical solution:

[0019] One end of the spring is fixedly connected to the lower surface of the spring, and the other end of the spring is fixedly connected to the upper surface of the side plate.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the electric motor drives the gear and rack to mesh, which in turn drives the slip ring to rise and fall along the support column, thereby achieving stepless adjustment of the signal light platform height. Combined with the one-way locking structure of the ratchet and pawl, it can be precisely fixed at different heights, solving the problem of limited visibility caused by the fixed height of traditional devices, and improving the visibility of signal lights and traffic safety in complex road sections.

[0022] 2. In this utility model, the limiting component uses spring-driven clamping plates one and two to elastically clamp the limiting ring, which can not only adapt to the errors of modular installation, but also prevent the signal light stand from shaking under conditions such as vehicle vibration, ensuring connection stability. Compared with traditional rigid connection, this structure enables the device to remain reliably fixed in different installation scenarios, improving overall practicality.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3This utility model provides an embodiment of a modular combined traffic signal device, including a support column 1, a slip ring 2 slidably connected to the outer wall of the support column 1, a signal light 3 disposed on the side wall of the slip ring 2, and an adjustment assembly disposed on the side wall of the support column 1; the adjustment assembly includes a side platform 5, the side wall of the side platform 5 is fixedly connected to the side wall of the support column 1, and the side platform 5 is driven by an electric motor 6 to realize the lifting and lowering adjustment of the signal light 3; a rack 4 is fixedly connected to the side wall of the slip ring 2, and the rack 4 meshes with a gear 7, the rotation of the gear 7 driving the slip ring 2 to move along the support column 1. The signal light stand 3 can be adjusted by sliding down. A ratchet 8 is fixedly connected to the side wall of the gear 7, and a pawl 9 is rotatably connected to the outer wall of the side platform 5. The ratchet 8 and the pawl 9 mesh with each other. The engagement of the ratchet 8 and the pawl 9 can effectively prevent the signal light stand 3 from sliding down due to gravity and keep the signal light stand 3 in a stable position after adjustment. This structure, through the cooperation of the ratchet 8 and the pawl 9, ensures that the signal light stand 3 can be stably fixed at a predetermined height during the adjustment process, avoiding displacement caused by the electric motor 6 stopping. The side wall of the signal light stand 3 is provided with a limit component.

[0032] Reference Figure 4 and Figure 5 The limiting assembly includes multiple inner shafts 10, one end of which is fixedly connected to the side wall of the signal light stand 3. Each inner shaft 10 has a limiting ring 11 fixedly connected to its outer wall. Multiple side plates 12 are fixedly connected to the side wall of the slip ring 2. Multiple fixing plates 13 are fixedly connected to the upper surface of each side plate 12. A fixing shaft 14 is fixedly connected between the multiple fixing plates 13. A clamping plate 15 is rotatably connected to the outer wall of the fixing shaft 14. A clamping plate 2 16 is rotatably connected to the outer wall of the fixing shaft 14. A connecting plate 17 is fixedly connected to the side walls of the clamping plate 15 and the clamping plate 2 16. A spring 18 is provided at the bottom of each connecting plate 17. One end of the spring 18 is fixedly connected to the lower surface of the spring 18, and the other end of the spring 18 is fixedly connected to the upper surface of the side plate 12.

[0033] Working principle: After the electric motor 6 is started, its output end drives the gear 7 to rotate. Since the gear 7 meshes with the rack 4 on the side wall of the slip ring 2, the rotation of the gear 7 is converted into the sliding of the slip ring 2 along the support column 1, thereby driving the signal light platform 3 to rise and fall. When a fixed height is required, the ratchet 8 and the pawl 9 automatically mesh. The one-way locking characteristic of the ratchet 8 mechanism prevents the slip ring 2 from sliding down due to gravity, ensuring that the signal light platform 3 is stable at the target height. During the adjustment process, the electric motor 6 can precisely control the number of rotations of the gear 7 to achieve stepless adjustment of the height of the signal light platform 3, adapting to the visibility requirements of different road sections. When the signal light platform 3 is connected to the side plate 12 on the side wall of the slip ring 2 through the inner shaft 10, the clamping plate 15 and the clamping plate 16 clamp the limiting ring 11 under the elastic force of the spring 18, forming an elastic clamping structure. After the signal light unit 3 is installed in place, the connecting plate 17 presses down the spring 18, causing the clamping plates 15 and 16 to fit tightly against both sides of the limiting ring 11, preventing the signal light unit 3 from swaying in the horizontal direction. This limiting structure utilizes the buffering characteristics of the spring 18 to accommodate installation errors of modular components and maintain connection stability under conditions such as vehicle vibration, ensuring a reliable connection between the signal light unit 3 and the slip ring 2.
