In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "upper, lower" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description. Without contrary instructions, these orientation words do not indicate and imply that the device or component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the protection scope of the present utility model; the orientation words "inner, outer" refer to the inside and outside relative to the contour of each component itself.

[0021] As Figures 1-5 shown, a surface-mounted LED downlight installation structure includes a lamp base 1 and a downlight body 2. The downlight body 2 includes a lamp housing and a lamp board installed in the lamp housing. LED lamp beads and leads are welded on the lamp board. A diffuser plate is installed at the light-emitting port of the lamp housing. A connecting frame 3 is fixedly installed in the lamp housing, and the upper end of the connecting frame is flush with the upper end of the lamp housing;

[0022] The lamp base includes a suspension plate 4, a suspension post 5 and a suspension disc 6. The two ends of the suspension post are respectively fixedly connected to the suspension plate and the suspension disc, and the suspension post is provided with a wire passing channel 7 through which it penetrates. A wire passing hole 8 is opened on the lamp board; an installation hole 9 is opened on the suspension plate, and the suspension plate is fixedly installed on the ceiling through expansion screws; the connecting frame is provided with a suspension disc through hole allowing the suspension disc to pass through; the connecting frame and the suspension disc are connected by a rotation-in-place locking structure.

[0023] In this way, during installation, the lamp base is fixedly installed on the ceiling through expansion screws, and then the downlight body is connected to the lamp base. During the disassembly and assembly process of the downlight body, no tools are required. Only the operator needs to rotate the lamp housing, and the rotation-in-place locking structure is used to achieve quick disassembly and assembly.

[0024] Specifically, the connecting frame is fixed in the lamp housing. The connecting frame can be fixed to the lamp housing by screws or can be adhesively connected. The connecting frame and the lamp housing are of a fixed structure. When connecting the downlight body to the lamp base, the operator holds the lamp housing and pushes it in the direction close to the lamp base. When the suspension disc passes through the suspension disc through hole, the upper end of the lamp housing abuts against the ceiling for in-place indication. Then the operator holds the downlight body and rotates it, and the rotation-in-place locking structure realizes the connection of the downlight body and the lamp base. When disassembly is required, only the operator needs to hold the downlight body and rotate it in the reverse direction, the rotation-in-place locking structure is unlocked, and the downlight body is taken off in the direction away from the lamp base.

[0025] The structure of the downlight body is an existing structure.

[0026] During implementation, the rotation-in-place locking structure includes several locking rods 11. The locking rods are fixedly installed at the lower end of the connecting frame along the same circumferential direction. A support plate 12 is fixed to the lower end of the locking rod. A locking groove 13 is formed in the circumferential direction of the hanging plate along the same circumferential direction. The locking rod is slidably matched with the locking rod.

[0027] In this way, when the hanging plate is located below the connecting frame, rotating the lamp housing drives the connecting frame to rotate. The locking rod enters the locking groove, and the support plate abuts against the lower end of the hanging plate. The connecting frame is supported by the support plate and the hanging plate.

[0028] During implementation, the in-place locking structure further includes several ball screws 14. The same number of internal thread cylinders 15 as the number of ball screws are fixed to the connecting frame. The ball screw is in threaded cooperation with the internal thread cylinder, and the lower end of the ball of the ball screw is located below the connecting frame. A card slot 16 for clamping the ball of the ball screw is formed in the hanging plate. In this way, through the setting of the ball screw, the ball is clamped into the card slot for in-place prompt and locking at the same time, which can better limit the position of the current hanging plate and the connecting frame and improve the reliability of installation.

[0029] During implementation, the connecting frame has a sunk platform formed by sinking along the direction close to the perforation of the hanging plate. The internal thread cylinder is fixedly installed on one side of the sunk platform close to the perforation of the hanging plate. Through the setting of the sunk platform, interference between the internal thread cylinder and the hanging plate is avoided.

[0030] During implementation, the hanging plate, the hanging column and the hanging plate are welded and connected in sequence. It is convenient for manufacturing.

[0031] Finally, it should be noted that those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. In this way, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
