[0012] Beneficial Effects

[0013] In the prior art, traditional classroom lamps are difficult to install, require many wiring procedures, are fixed in one position and are inconvenient to adjust. When the lamp needs to be repaired, it is very troublesome to replace and disassemble it, which is time-consuming and laborious. In addition, the tightness between the lamp mounting bracket and the lamp is not high. When an earthquake occurs or the bracket ages, the connection between the bracket and the lamp is prone to fall off. To address such problems, the utility model adopts a detachable structure. After the mounting bracket is fixed to the top of the wall, the plug at one end of the male and female buckle on the top of the lamp is inserted into the slot at the bottom of the bracket. The top of the plug squeezes the card. When the card moves to the bottom of the plug, the spring causes the card to pop out and engage with the bottom surface of the plug end. Fix the bracket and the snap fastener, and then connect the snap fastener to the lamp. When the lamp needs to be disassembled, move the plug inward again, and the front end face of the limit ring squeezes the clamp. When the clamp moves to the rear end face of the limit ring, under the action of the spring, the clamp pops out and engages with the rear end face of the limit ring. Since the rear end face is set as an inclined plane, the clamp pulls the limit ring to the left until it is in fit with the bottom surface of the plug end. The clamp then detaches from the limit ring, thereby detaching the slot from the plug. Under the action of the reset spring, the limit ring returns to its original position, thereby separating the snap fastener and the bracket, which is convenient for disassembly and assembly, and easy to repair and replace after damage, reducing maintenance time and avoiding interrupting students' classes.
