[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model discloses a snap-connected downlight back cover assembly. When the user needs to assemble the lamp wires on one side of the back cover tube assembly, the pull rod can be pulled in advance in the direction away from the cavity, and the pull rod drives the plug block to shrink into the cavity. At this time, the first spring is compressed and deformed, and the plug block drives the second clamp block to move in the direction away from the first clamp block. A large gap is left between the first clamp block and the second clamp block. One end of the assembly line is passed through the hole and extended into the back cover tube assembly. When the assembly line is connected with the components inside the back cover tube assembly, the user releases the pull rod originally pulled, and the first spring recovers its elastic shape at this time. When the first clamp is moved closer to the first clamp, the second clamp is moved closer to the first clamp, so that the assembly line is tightly clamped and fixed between the first clamp and the second clamp, thus completing the assembly purpose. This arrangement uses a snap-fit ​​component provided on one side of the rear cover barrel assembly, and the snap-fit ​​structure can position and clamp the lamp assembly line. The operation is simple and convenient, and the rear cover barrel assembly can achieve the purpose of fixing the assembly line, and the elastic force of the spring itself is used to achieve the assembly effect, thereby improving the convenience of assembly.

[0016] 2. The utility model discloses a snap-on connection type downlight rear cover assembly. In the utility model, the diffusion plate is installed on the front side of the lamp tube assembly, which is directly in front of the LED light source. This ensures that the light of the lamp can be evenly diffused and dispersed, avoiding over-concentrated or uneven lighting effects, so that the light is diffused during the refraction process, thereby greatly reducing the anti-glare ability of the downlight. When the user needs to maintain the downlight, the tube cover and the diffusion plate can be separated and disassembled from the lamp tube assembly. The user rotates the first screw rod in the opposite direction to make the first screw rod rotate in the opposite direction, and the two sets of movable limit plates move in the same direction. As the installation cavity box moves away from each other in the horizontal direction, the two sets of movable limit plates drive the two sets of arc clamping blocks to move away from each other until the two sets of arc clamping blocks are completely away from the engaging rod, giving up the engaging fixation of the engaging rod, and then the user pulls the tube cover upwards to pull the plug-in rod out of the hole cavity groove of the lamp tube assembly, and the tube cover and the lamp tube assembly are engaged and separated, so that the diffuser plate can be disassembled from the downlight; this setting is simple and convenient to operate through the snap-on connection of the snap-on assembly, which is convenient for users to disassemble the diffuser plate from the lamp tube assembly, which can not only improve the convenience of assembly, but also improve the convenience of lamp maintenance.
