[0025] In the above solution provided by the present invention, when the downlight is unloaded, a locking assembly is provided, and the locking assembly locks the mounting foot 20 that is flipped into place along the Y direction, so that when the downlight and the mounting foot 20 are pulled out of the mounting hole, the mounting foot 20 will not be flipped by the driving member 14 to pinch the operator's hand, thereby improving the convenience and safety of the downlight unloading operation. For the implementation of the locking assembly, a spring-driven pin can be used to lock the mounting foot 20. It is preferably implemented in the following manner.
[0026] A further solution is: an assembly part 12 is provided on the outer wall of the mounting seat 10, a mounting shaft is provided on the assembly part 12, one end of the mounting foot 20 is rotatably mounted on the mounting shaft, the driving member 14 is composed of a winding spring provided on the mounting shaft, the locking assembly includes a locking hook 31 for hooking and locking one end of the mounting foot 20, and the locking adjustment assembly is used to adjust the state of the locking hook 31. The assembly part 12 can be specifically composed of a sheet metal part, and can be as follows: Figure 3 The locking hook 31 is provided to lock the mounting foot 20 by hooking. This embodiment is convenient and fast to lock the mounting foot 20, and can also be unlocked conveniently and reliably. A more detailed solution is as follows: Figure 2As shown, the mounting foot 20 is formed by bending a plate, and the mounting foot 20 includes a main body 21. The length direction of the main body 21 is perpendicular to the length direction of the mounting axis, and the plate surface of the main body 21 is parallel to or coincides with the length direction of the mounting axis. One end of the main body 21 is provided with two relatively arranged long strip-shaped connecting parts 22, and the connecting parts 22 are provided on the plate surface of the main body 21 away from the lighting panel 11. The length direction of the connecting part 22 is perpendicular to the length direction of the mounting axis, and the plate surface of the connecting part 22 and the plate surface of the main body 21 are arranged at an angle. The end of the connecting part 22 away from the main body 21 is rotatably assembled through the opening of the mounting hole and the mounting axis, and the locking hook 31 hooks the connecting part 22 to lock the mounting foot 20. The locking hook 31 is arranged horizontally, and the length direction of the locking hook 31 is arranged perpendicular to the length direction of the mounting shaft. The end of the locking hook 31 close to the mounting foot 20 is arranged in a cantilevered shape, and a hook body 32 for hooking the mounting foot 20 is arranged at the end. The locking hook 31 is made of elastic metal material, and the locking adjustment component is used to adjust the elastic deformation of the locking hook 31 so that the hook body 32 and the connecting part 22 are separated. Two locking hooks 31 are correspondingly arranged on the side of a mounting foot 20, and the mounting foot 20 is located between the two locking hooks 31. The end of the locking hook 31 is extended to the side close to the mounting foot 20 to set the hook body 32, and the two locking hooks 31 respectively hook and lock the two connecting parts 22. The spacing between the two connecting parts 22 gradually increases in the direction away from the main body 21, and the hook body 32 is located on the moving path of the connecting part 22; when the mounting foot 20 rotates along the Y direction, the connecting part 22 first moves outward against the hook body 32, and when the connecting part 22 completely passes over the hook body 32, the hook body 32 hooks and locks the edge of the connecting part 22 close to the main body 21 through elastic reset, and the Y direction is the rotation direction opposite to the X direction. The above scheme can be used to install the downlight more conveniently and simply. When installing the downlight, first flip the two mounting feet 20 along the Y direction so that the other end of the mounting foot 20 is flipped to a position away from the lighting panel 11, and the locking hook 31 is first avoided by the connecting part 22, and then elastic reset is performed to lock the mounting foot 20. During assembly, the wires in the ceiling are electrically connected to the connecting wires on the downlight, and then the two mounting feet 20 and the mounting seat 10 are inserted into the mounting hole from the bottom of the mounting hole, so that the mounting feet 20 are completely moved to the upper side of the mounting hole, and then the two pull ropes 34 are pulled to make the locking hooks 31 unlock the mounting feet 20. The mounting feet 20 are driven by the driving member 14 to flip over so that the downlight is securely clamped and installed in the mounting hole.When the downlight needs to be disassembled or replaced, the operator operates the lighting panel 11 to pull the downlight downward, and the periphery of the mounting hole abuts against the mounting foot 20 to cause the mounting foot 20 to flip over. When the mounting foot 20 is flipped into place, the locking hook 31 hooks and locks the mounting foot 20. When the downlight is completely pulled out of the mounting hole, the mounting foot 20 will not pinch the hand due to the drive of the driving member 14, thereby realizing reliable and convenient installation and unloading of the downlight and avoiding pinching of the hand.
[0027] Two to three mounting feet 20 are arranged at intervals along the circumference of the mounting seat 10. Preferably, two mounting feet 20 are arranged opposite to each other on the mounting seat 10, and a mounting bracket is arranged on the top of the mounting seat 10. The mounting bracket is composed of a groove-shaped member with a notch pointing to the upper side of the mounting seat 10, and the other end of the locking hook 31 is fixedly installed at the notch of the groove-shaped member 33. The locking adjustment member includes a pull rope 34 connected to the locking hook 31. The two locking hooks 31 located on the same side of the groove-shaped member 33 are respectively fixedly assembled and connected to the two ends of the same pull rope 34. Figure 4 As shown, the locking hook 31 and the mounting foot 20 can be unlocked by pulling the pull rope 34. In addition, since the sizes of the mounting holes opened on the ceiling are different, a further solution is as follows Figure 5 As shown, two sliders 35 are provided on the mounting seat 10, and the two sliders 35 are respectively provided corresponding to the two mounting feet 20, and the two locking hooks 31 on the outer side of the same mounting foot 20 are installed on the same slider 35, and the slider 35 is adjustedly installed on the mounting seat 10 along the radial sliding direction of the mounting seat 10, and a spacing adjustment component for adjusting the spacing between the two sliders 35 is provided between the two sliders 35. In detail, the spacing adjustment component includes an adjustment rod 36 arranged along the radial direction of the mounting seat 10, and a threaded hole is provided on the slider 35, and the thread rotation directions of the threaded holes on the two sliders 35 are opposite. Two thread segments are provided on the adjustment rod 36, and the thread rotation directions of the two thread segments are opposite. Each thread segment and each slider 35 respectively form a screw nut adjustment mechanism, and an operating part for operating the adjustment rod 36 to rotate is provided on the adjustment rod 36, and the adjustment rod 36 is rotated to adjust the two sliders 35 to move closer or farther from each other. More specifically, the slider 35 can be slidably installed on the mounting bracket, that is, in the groove member 33. At this time, a baffle is provided at the notch of the groove member 33 to prevent the slider 35 from moving out of the groove member 33. The spacing between the two sliders 35 is adjusted mainly to meet the assembly requirements of mounting holes with different apertures, thereby improving adaptability and ensuring that the locking hook 31 can reliably lock the mounting foot 20 when the downlight is unloaded, and the length of the locking hook 31 will not affect its installation or unloading in mounting holes of different sizes.
