Description

Technical Field

[0001] This utility model relates to the field of traffic signal lights, and more specifically, to a highly efficient, sealed, and moisture-proof traffic signal light. Background Art

[0002] Traffic lights are commonly used to manage traffic flow, indicating when pedestrians and vehicles can cross intersections or roads. They are widely used at urban and rural road intersections, pedestrian crossings, and other locations. The use of traffic lights is crucial for maintaining traffic order and ensuring road safety; clear instructions and standardized traffic signals help reduce traffic accidents and improve traffic efficiency.

[0003] Existing traffic lights are inconvenient to maintain. When a light malfunctions or requires repair, the entire light may need to be disassembled or replaced, increasing the complexity and cost of maintenance. Complete repairs or replacements of traffic lights require significant downtime, disrupting normal traffic flow. At busy intersections or roads, increased downtime can lead to congestion and delays, impacting urban traffic order and efficiency. Furthermore, the existing traffic light sealing structure is simple and inadequate, potentially resulting in poor waterproofing. This can lead to safety hazards such as moisture buildup, water ingress, and electrical leakage, even affecting the normal operation and lifespan of the traffic lights. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of the prior art and provide a highly efficient, sealed, and moisture-proof traffic signal light.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a traffic signal light, comprising a housing, multiple lamp head units, a pressure plate connected to the housing, and a cover hinged to the housing. Each lamp head unit includes an inner shell, a light-transmitting unit, and a light-emitting unit. The light-emitting unit includes a mounting base, a circuit board mounted on the mounting base, and multiple LED beads located on the circuit board. The mounting base has multiple side ears. The light-transmitting unit includes a light-transmitting plate connected to an outer circumferential plate, and the outer circumferential plate connected to an annular abutment plate capable of abutting against the mounting base. The inner shell includes a first panel with multiple circular through holes, the first panel connected to a first surrounding frame, and the first surrounding frame connected to a first rectangular frame. The first panel is connected to a limiting frame that surrounds the annular abutment plate and the mounting base. The light-transmitting plate can pass through a circular through hole. The annular abutment plate can abut against the first panel. Multiple fixing blocks are fixed inside the first panel. The side ears are fixedly connected to the fixing blocks by a first bolt. The outer shell includes a second panel with multiple rectangular through holes. The rectangular through holes are connected to a second surrounding frame that surrounds the inner shell. The second surrounding frame is connected to a second rectangular frame that abuts against the first rectangular frame. The pressure plate can abut against the first rectangular frame of multiple lamp head units. The pressure plate and the second panel are fixedly connected by a second bolt. The cover and the outer shell are fixedly connected by a third bolt.

[0006] Furthermore, the inner side of the cover has a rectangular frame-shaped first sealing frame, and the outer shell has a rectangular frame-shaped abutment frame capable of abutting the sealing frame.

[0007] This increases the sealing effect between the cover and the outer shell.

[0008] Furthermore, the inner side of the second rectangular frame has a rectangular frame-shaped second sealing frame, which can abut against the first rectangular frame.

[0009] This results in a good seal between the lamp holder unit and the outer casing.

[0010] Furthermore, the outer circumferential plate has an inner circumferential plate connected to the light-transmitting plate, and a first sealing ring is provided between the inner and outer circumferential plates. The mounting base has an annular flange that can abut against the first sealing ring.

[0011] This allows for a better seal between the light-transmitting unit and the light-emitting unit.

[0012] Furthermore, the annular abutment plate has a second sealing ring, which can abut against the inner side of the first panel.

[0013] This ensures a good seal between the light-transmitting unit and the inner shell.

[0014] Furthermore, the side ear has a first through hole that matches the first bolt, and the fixing block has a first threaded hole that matches the first bolt.

[0015] Thereby, the light emitting unit is stably mounted at the inner housing.

[0016] Furthermore, the pressure plate has a second through hole that matches the second bolt, and the second panel has a second threaded hole that matches the second bolt.

[0017] This allows the pressure plate to be fixedly connected to the second panel, and to press and fix multiple lamp head units.

[0018] Furthermore, the cover has a third through hole matched with a third bolt, and the housing has a third threaded hole matched with the third bolt.

[0019] Thus, the cover is firmly connected to the housing.

[0020] Furthermore, both the lamp holder unit and the rectangular through hole have three.

[0021] Furthermore, each mounting seat has four side ears, and each inner shell has four fixing blocks.

[0022] Thus, the light-emitting unit is stably connected to the inner shell.

[0023] Furthermore, the top and bottom ends of the outer casing are both fixed with mounting bases, and the mounting bases are connected with studs.

[0024] This makes it easier to install fixed traffic lights.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 1. The traffic light of the present application has a modular installation of the internal lamp holder unit, which is easy to install, and each lamp holder unit can be disassembled and replaced independently, which is convenient for repair and replacement, thereby reducing the time required for maintenance and repair.

[0027] 2. The traffic light of the present application has tight connections between various components and good overall sealing, thereby providing good rainproof effect, thereby improving the reliability and durability of the traffic light in outdoor environments. Attached Figure Description
