Description

Technical Field

[0001] This utility model relates to the technical field of traffic lights, specifically to a combined traffic signal light module. Background Technology

[0002] Traffic lights effectively regulate traffic conditions, significantly improving traffic flow, increasing road capacity, and reducing traffic accidents. Existing traffic lights typically integrate red, green, and yellow lights into a single unit for convenient centralized installation and management.

[0003] For example, Chinese patent CN204596162 U discloses a traffic signal light that integrates multiple traffic signal lights into a single light box, which facilitates integrated installation and use.

[0004] However, with integrated traffic lights, if one of the lights fails and needs repair or replacement, the entire integrated traffic light system must be replaced, making maintenance cumbersome and costly.

[0005] Therefore, how to make integrated traffic lights easily disassembled for individual repair and replacement while maintaining low maintenance costs has become a pressing problem in this field. To address this issue, publication number CN202323522084.9 discloses a combined traffic light, including a signal light comprising a lamp cover, LEDs, and a lamp housing. The LEDs are housed in the lamp housing, and the lamp cover is detachably connected to the lamp housing via a connecting device. Several signal lights are detachably assembled together via a combination device. The combined traffic light provided by this utility model uses a detachable design, facilitating the individual disassembly of the signal light to be replaced when a single signal light is damaged. Furthermore, the detachable lamp housing and lamp cover allow for easy separation of the lamp cover from the lamp housing for repair, resulting in convenient maintenance and low costs. Existing traffic lights have the following problems: They are assembled by disassembly using a combination device, which includes a combination slot and assembly components. The combination slot is located within the assembly components, and the ends of the assembly components have serrations. The assembly components on the first and second traffic lights interlock via the serrations. At this point, the combination slots on the first and second traffic lights correspond and connect. A connecting pin is passed through the combination slots on the first and second traffic lights to connect the combination devices. This method of assembly is cumbersome, and when disassembly is needed, the connecting pin must be removed before the first and second traffic lights can be separated. The installation, connection, and disassembly steps are tedious and time-consuming, affecting maintenance efficiency and thus impacting normal use. Furthermore, since traffic lights are located outdoors, environmental factors (blowing, vibration, etc.) can cause the connecting pin and combination slot to loosen, leading to a loosening of the serrations and causing the assembly device to detach. Additionally, this combination device has a complex structure and high production costs. Utility Model Content
