Description

Technical Field

[0001] This utility model relates to the field of traffic signal lights, specifically a spiral-type, wiring-free road traffic signal light. Background Technology

[0002] Traffic lights are signals that direct traffic flow and generally consist of red, green, and yellow lights. A red light indicates that passage is prohibited, a green light indicates that passage is permitted, and a yellow light indicates a warning. Traffic lights are categorized as follows: motor vehicle traffic lights, non-motor vehicle traffic lights, pedestrian crossing traffic lights, directional indicator lights (arrow traffic lights), lane traffic lights, flashing warning traffic lights, and level crossing traffic lights.

[0003] Traditional traffic lights require independent installation of components such as the light head, controller, and power supply, and the wiring is complex, significantly increasing the construction period and affecting the efficiency of traffic light installation. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a spiral-type wiring-free road traffic signal light to solve the technical problems of current traffic signal lights requiring independent installation of lamp heads, controllers, power supplies and other components, and complicated wiring, which greatly increases the construction period and affects the efficiency of traffic signal light installation.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A spiral-type, wiring-free road traffic signal light is designed, comprising:

[0006] The mounting mechanism includes three covers hinged to one side of the housing. Each of the three covers has a first internal thread hole, and each of the three first internal thread holes has a lamp body. The three lamp bodies emit red light, yellow light, and green light respectively, and each of the three lamp bodies has a first external thread on its outer side.

[0007] The connecting mechanism includes three connecting cylinders fixedly installed inside the housing and connecting posts fixedly installed at the rear ends of three lamp bodies. A conductive spring is fixedly connected to the middle of the end of each of the three connecting posts away from the lamp body. A conductive cylinder is fixedly connected to the inner wall of each connecting cylinder, and a threaded conductive sheet is fixedly connected to the inner wall of each conductive cylinder. A through hole is opened in the middle of the bottom end of each conductive cylinder. A positive conductive sheet is fixedly connected to the middle of the bottom end of each connecting post, and a threaded groove is opened on the outer side of each connecting post. A negative conductive sheet is fixedly connected in the threaded groove, and the conductive spring corresponds to the positive conductive sheet.

[0008] Preferably, a ball hole is provided at the middle of the end of the conductive spring away from the connecting post, and a conductive ball is rotatably connected inside the ball hole, with one-third of the conductive ball placed outside the ball hole.

[0009] Preferably, a limiting ring is fixedly connected to the outer side of the lamp body. The outer diameter of the limiting ring is larger than the diameter of the first internal thread hole, and an anti-slip groove is provided on the outer side of the limiting ring.

[0010] Preferably, one end of the limiting ring is fixedly connected to an annular rubber ring, and the annular rubber ring is elastic.

[0011] Preferably, both the connecting column and the connecting cylinder are insulators, and both are made of alumina ceramic.

[0012] Preferably, the thickness of the positive electrode conductive sheet is the same as the thickness of the bottom end of the conductive cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model combines a first external thread, a cover, a housing, a first internal threaded hole, a conductive cylinder, a threaded groove, a threaded conductive sheet, a negative conductive sheet, a positive conductive sheet, and a conductive spring. The lamp body is fixed by screwing the first external thread into the first internal threaded hole on the cover. During the rotational installation process, the connecting post at the bottom of the lamp body is simultaneously inserted into the conductive cylinder, and the threaded groove on its surface forms a spiral contact with the threaded conductive sheet inside the conductive cylinder, achieving electrical continuity. When the lamp body is fully tightened, the threaded conductive sheet automatically engages with the negative conductive sheet, while the conductive spring precisely abuts against the positive conductive sheet, achieving instantaneous circuit conduction and illumination. This simultaneous completion of mechanical connection and electrical contact completely eliminates the traditional wiring process, significantly shortens the construction cycle, and further improves the efficiency of traffic light installation.

[0015] 2. This utility model combines a ball hole and a conductive ball. During the rotation and installation of the lamp body, the built-in conductive ball forms a dynamic rolling contact with the positive electrode conductive sheet, transforming the sliding friction of the traditional conductive spring into efficient rolling friction. This reduces the contact resistance by 40% and the friction force by 60%, significantly reducing electrode wear. It is particularly suitable for traffic signal facilities that require frequent maintenance, greatly reducing maintenance costs while ensuring electrical reliability. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] Example 1: A spiral-type, wiring-free road traffic signal light, see [link / reference] Figures 1 to 6The system includes: a mounting mechanism comprising three covers 11 hinged to one side of the housing 1, each cover 11 having a first internal threaded hole 12, and each of the three first internal threaded holes 12 housing a lamp body 2 emitting red, yellow, and green light respectively; and each of the three lamp bodies 2 having a first external thread 24 on its outer side, which is adapted to the first internal threaded hole 12; and a connecting mechanism comprising three connecting cylinders 3 fixedly installed inside the housing 1 and connecting posts 21 fixedly installed at the rear ends of the three lamp bodies 2, both the connecting posts 21 and the connecting cylinders 3 being insulators made of alumina ceramic; and each of the three connecting posts 21 having a conductive spring 4 fixedly connected to the middle of its end away from the lamp body 2. The plate 4 is electrically connected to the positive electrode of the lamp body 2 via a wire. A conductive cylinder 31 is fixedly connected to the inner wall of the connecting cylinder 3. A threaded conductive plate 32 is fixedly connected to the inner wall of the conductive cylinder 31. A through hole 33 is opened in the middle of the bottom end of the conductive cylinder 31. A positive electrode conductive plate 34 is fixedly connected to the middle of the bottom end of the inner cavity of the connecting post 21. The thickness of the positive electrode conductive plate 34 is the same as the thickness of the bottom end of the conductive cylinder 31. A threaded groove 22 is opened on the outer side of the connecting post 21. The threaded groove 22 is adapted to the threaded conductive plate 32. A negative electrode conductive plate 23 is fixedly connected in the threaded groove 22. The negative electrode conductive plate is electrically connected to the negative electrode of the lamp body 2 via a wire. The conductive spring plate 4 corresponds to the positive electrode conductive plate 34. Both the positive electrode conductive plate 34 and the threaded conductive plate 32 are electrically connected to the positive and negative electrodes of the external power supply via wires, respectively.

[0025] During operation, the lamp body 2 is screwed into the first internal threaded hole 12 on the cover 11 via the first external thread 24. During the rotational installation process, the connecting post 21 at the bottom of the lamp body 2 is simultaneously inserted into the conductive cylinder 31, and the threaded groove 22 on its surface forms a spiral contact with the threaded conductive piece 32 inside the conductive cylinder 31, thus achieving electrical continuity. When the lamp body 2 is fully tightened, the threaded conductive piece 32 automatically engages with the negative electrode conductive piece 23, while the conductive spring 4 precisely abuts against the positive electrode conductive piece 34, achieving instantaneous circuit conduction and illumination. This simultaneous completion of mechanical connection and electrical contact completely eliminates the traditional wiring process, significantly shortens the construction cycle, and further improves the efficiency of traffic light installation.

[0026] For details, see Figure 4 — Figure 6The conductive spring 4 has a ball hole 42 at the middle of the end away from the connecting post 21. A conductive ball 41 is rotatably connected inside the ball hole 42. One-third of the conductive ball 41 is placed outside the ball hole 42. During the rotation and installation of the lamp body 2, the built-in conductive ball 41 forms a dynamic rolling contact with the positive electrode conductive sheet 34, which transforms the sliding friction of the traditional conductive spring 4 into a high-efficiency rolling friction. This reduces the contact resistance by 40% and the friction force by 60%, significantly reducing electrode wear. It is particularly suitable for traffic signal facilities that require frequent maintenance, and greatly reduces maintenance costs while ensuring electrical reliability.

[0027] Further, see Figure 5 A limiting ring 5 is fixedly connected to the outer side of the lamp body 2. The outer diameter of the limiting ring 5 is larger than the diameter of the first internal thread hole 12, and an anti-slip groove is provided on the outer side of the limiting ring 5. By setting the limiting ring 5, on the one hand, it is convenient for personnel to rotate and disassemble the lamp body 2 by hand, and on the other hand, it restricts the axial travel of the lamp body 2 into the housing 1, ensuring that the conductive components reach the optimal contact depth and effectively preventing poor electrical contact caused by over-rotation.

[0028] It is worth noting that, see Figure 5 One end of the limiting ring 5 is fixedly connected to an annular rubber ring 51, and the annular rubber ring 51 is elastic. By setting the annular rubber ring 51, the sealing performance of the limiting ring 5 in contact with the shell cover 11 is improved, and the waterproof effect of the connection between the lamp body 2 and the shell cover 11 is further improved.
