Description

Technical Field

[0001] This application relates to the field of signal controller technology, and in particular to an LED signal controller. Background Technology

[0002] LED signal lights are mainly used in urban rail transit as signal indicating equipment in areas such as subway main lines, sidings, parking lots, and depots. Specifically, they are used for signal display of entering stations, routes, exiting stations, and shunting. These signals are lower in height, with only two light positions, and can convey accurate driving instructions to train drivers through combinations of red and green lights, ensuring the safe and efficient operation of railway transportation. An LED signal light consists of multiple signal units and a base. The signal units are vertically installed, and each unit includes a housing, a cover, and an LED external lens. The cover and LED external lens are installed at the front and rear ends of the housing, respectively. Conventional LED signal lights are assembled with multiple housings vertically installed and fixed with bolts. When replacing a single signal unit, each bolt must be removed individually, resulting in low replacement efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an LED signal controller in response to the defects and shortcomings of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The device includes multiple signal units and a base. The signal units are arranged vertically, and the base is located at the lower end of the bottom signal units. Each signal unit includes a housing and a cover. The cover covers one side of the housing. The lower end of the housing has a first connecting seat, and the upper end of the housing has a second connecting seat. The first connecting seat of the housing is sleeved on the outer periphery of the second connecting seat of the lower part of the housing. The side wall of the first connecting seat has a first connecting hole, and the side wall of the second connecting seat has a second connecting hole. Connecting plates pass through the first connecting hole and the second connecting hole.

[0005] Preferably, the side wall of the first connecting hole is provided with a limiting rod, and the side wall of the connecting plate is provided with a limiting groove for the limiting rod to slide.

[0006] Preferably, the second connecting seat is provided with a top block, and a compression spring is provided between the top block and the housing, with the upper end of the top block pressing against the side wall of the connecting plate.

[0007] Preferably, the upper end face of the top block is provided with a fixing block, and the side wall of the connecting plate is provided with a fixing groove for the fixing block to be engaged and fixed.

[0008] Preferably, the side wall of the second connecting seat is provided with a mounting block, and the side wall of the top block is provided with a mounting groove for the mounting block.

[0009] Preferably, a sealing ring is provided between the first connecting seat and the housing.

[0010] Preferably, one end of the connecting plate is provided with a pull block.

[0011] In summary, this application includes at least one of the following beneficial technical effects: 1. When a single signal unit needs to be replaced, simply pull the connecting plate out of the first and second connecting holes. Then the first and second connecting sleeves can be separated from each other, and the two adjacent housings can be separated. This allows the single signal unit to be quickly removed from the LED signal unit and the normal single signal unit to be installed, improving the replacement efficiency of the LED signal unit. 2. When the connecting plate is inserted into the first connecting hole and the second connecting hole in sequence, the top block is pressed until the fixing block is snapped into the fixing groove, so that the connecting plate is fixed between the first connecting seat and the second connecting seat, thereby improving the stability of the connecting plate.
