Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0043] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0044] Example 1, please refer to Figures 1 to 5 This utility model proposes a quick-installation device 100 for lighting fixtures, including a bracket 1, rotating posts 2 and hooks 3 disposed at two opposite ends of the bracket 1, elastic latches 4, and rotating seats 5. The rotating seats 5 have rotating holes 51. The elastic latches 4 and rotating seats 5 can be disposed on opposite sides of the lamp frame 201 of the lighting fixture 200. The bracket 1 is used for installation on the building surface and for suspending the lighting fixture 200. The bracket 1 is made of metal, such as stainless steel. When installing the lighting fixture, the bracket 1 needs to be installed on the ceiling or wall surface of the building first. The bracket 1 has holes for fixing to the building surface with screws, etc. In this embodiment, the elastic latches 4 and rotating seats 5 are disposed on opposite sides of the lamp frame 201 of the lighting fixture 200. Figure 3 As shown, a lamp frame 201 is provided on the back of the lamp 200, and an elastic latch 4 and a rotating seat 5 are respectively provided on the front and rear sides of the lamp frame 201.

[0045] During installation, the rotating column 2 on the bracket 1 of this embodiment is inserted into the rotating hole 51 of the rotating seat 5 and can rotate within the rotating hole 51. The hook 3 can be pressed into the elastic lock 4 and locked by the elastic lock 4.

[0046] like Figures 4 to 5 As shown, the installation process of the device 100 and the lamp 200 in this embodiment is as follows: First, the bracket 1 with the rotating column 2 and the hook 3 is fixed to the ceiling with screws, etc. Then, the rotating seat 5 and the elastic buckle 4 are installed on the lamp frame 201 on the back of the lamp 200. Then, the lamp 200 and the bracket 1 are first aligned at an angle so that the rotating column 2 on the bracket 1 is inserted into the rotating hole 51 of the rotating seat 5 on the lamp 200. Figure 6As shown, at this time, the rotating column 2 on the bracket 1 has been inserted into the rotating hole 51 of the rotating seat 5. Preferably, as Figure 4 As shown in the diagram, in this embodiment, the lamp 200 and the bracket 1 are initially joined at a 90-degree angle, thus bringing the lamp 200 closest to the ground. When the rotating column 2 of the bracket 1 is inserted into the rotating hole 51, one side of the lamp 200 (as shown in the diagram)... Figure 4 The upper side of the lamp 200 is movably connected to one end of the bracket 1, so the lamp 200 will not fall off. Then, the lamp 200 is rotated toward the bracket 1 (as shown). Figure 4 In the process of rotating the lamp 200 upwards, the rotating column 2 rotates within the rotating hole 51, causing the lower side of the lamp 200 to gradually approach the bracket 1, making them more parallel. This causes the elastic latch 4 on the lower side of the lamp 200 to gradually approach the hook 5 on the upper bracket 1. Once they are in contact, push the lamp 200 upwards again, causing the hook 3 on the bracket 1 to press into the elastic latch 4 on the lamp 200 and lock it in place. Figure 5 The status indicates that the installation is complete.

[0047] In this embodiment, the installation process of the device 100 and the lamp 200 is completed by first aligning one side of the lamp 200 with the bracket 1 and then rotating it so that the other side of the lamp 200 is locked with the bracket 1. The entire installation process only requires one worker, saving labor and installation costs. At the same time, the installation is quick and convenient, which is conducive to the promotion of surface-mounted LED lamps 200.

[0048] Preferably, such as Figure 7 and Figure 8 As shown, the rotating base 5 is an L-shaped plate, and the rotating hole 51 includes an insertion hole 511 disposed on the L-shaped plate and a sliding groove 512 communicating with the insertion hole 511. The rotating column 2 can slide within the sliding groove 512. In this embodiment, the L-shaped plate includes a first plate surface 52 and a second plate surface 53 perpendicularly connected to the first plate surface 52. The rotating hole 51 is provided on the first plate surface 52. The mounting hole is provided on the second plate surface 53, which can be installed on the lamp frame 201 of the lamp 200. In this embodiment, the rotating hole 51 on the first plate surface 52 includes an insertion hole 511 and a sliding groove 512. The insertion hole 511 is used for the rotating column 2 to be inserted into it and abut against the hole wall, so that the bracket 1 is hung with the rotating base 3. At the same time, the rotating column 2 can also rotate within the insertion hole 511 while closely adhering to the hole wall, thereby completing the installation of the device 100 and the lamp 200. The sliding groove 512 allows for adjustment of the lateral relative position between the light fixture 200 and the mounting bracket 1 during installation, facilitating the smooth engagement of the hook 3 into the elastic locking buckle 4. Furthermore, once the hook 3 is engaged in the elastic locking buckle 4, as... Figure 8As shown, the lamp 200 is moved laterally to the right, causing the rotating column 2 to move to the right, that is, to enter the sliding groove 512 and move to the right. This allows the hook 3 to be stably locked in the elastic latch 4 without coming off.

[0049] Furthermore, such as Figure 8 As shown Figure 5 As shown, the end of the rotating column 2 is provided with an anti-slip cap 21. The outer diameter of the anti-slip cap 21 is smaller than the diameter of the insertion hole 511 but larger than the width of the sliding groove 512. In this way, the entire rotating column 2 can be smoothly inserted into the insertion hole 511 of the rotating seat 5, and when the rotating column 2 is located in the sliding groove 512 after installation, the rotating column 2 will not slip out of the rotating seat 5, ensuring the stability of the connection after installation.

[0050] Specifically, such as Figure 9 As shown, the hanging bracket 1 in this embodiment includes a hanging plate 11 forming an I-shaped structure, a first bracket 12 and a second bracket 13 disposed at both ends of the hanging plate 11. The rotating column 2 and hook 3 are disposed at opposite ends of both the first bracket 12 and the second bracket 13. In this embodiment, the first bracket 12 and the second bracket 13 are respectively disposed at the left and right ends of the hanging plate 11. The I-shaped structure of the hanging bracket 1 makes the overall structure of the hanging bracket 1 stable and strong. Meanwhile, as... Figure 9 As shown, in this embodiment, the first bracket 12 and the second bracket 13 are respectively provided with rotating columns 2 and hooks 3 at their front and rear ends. Thus, the hanging bracket 1 in this embodiment has two rotating columns 2 and two hooks 3. Correspondingly, two rotating seats 5 and two elastic buckles 5 need to be provided on the lamp frame 201 of the lamp 200 for cooperation. In this way, there are four force-bearing positions between the lamp 200 and the hanging bracket 1, so that the lamp 200 is stably and evenly stressed after installation, and the connection between the two is more secure.

[0051] In this embodiment, the mounting plate 11, the first bracket 12, and the second bracket 13 are separate components connected by screws. It can be understood that in other embodiments, the mounting plate 11, the first bracket 12, and the second bracket 13 may also be an integral structure.

[0052] In this embodiment, both the first bracket 12 and the second bracket 13 include an elongated frame 14. The frame 14 is provided with mounting holes for connecting to the hanging plate 11 by screws.

[0053] like Figure 10 As shown, taking the first support 12 as an example (the first support 12 and the second support 13 have the same structure), one end of the frame 14 in this embodiment is provided with a folding plate 141, and the rotating column 2 is provided on the folding plate 141. Specifically, as shown... Figure 10As shown, a fixing lug 142 is provided on the side of the folded plate 141. The fixing lug 142 has a connecting hole. The rotating column 2 is connected and fixed to the connecting hole on the fixing lug 142. In this embodiment, the rotating column 2 includes a rod 22 and an anti-detachment cap 21 provided at one end of the rod 22. The other end of the rod 22 is provided with a thread and is screwed to the connecting hole of the fixing lug 142.

[0054] In this embodiment, the hook 3 includes a straight plate 31 perpendicular to the frame 14 at the other end of the frame 14 and a slot 32 formed on the straight plate 31. When the straight plate 31 is pressed into the elastic latch 4, the latching part of the elastic latch 4 passes through the slot 32 and fastens the straight plate 31 inside the elastic latch 4.

[0055] Preferably, the slot 32 in this embodiment is a rectangular slot. The rectangular slot facilitates the insertion of the hook 3 into the elastic latch 4.

[0056] In this embodiment, the hook 3 is an integral structure with the first bracket 12 and the second bracket 13. In other embodiments, the hook 3 can be a separate structure from the first bracket 12 and the second bracket 13.

[0057] As one implementation method, such as Figure 11 and Figure 12 As shown, the elastic latch 4 in this embodiment includes a portal frame 41, a first spring 42, a second spring 43, and a movable plate 44. The portal frame 41 includes a crossbar 411 and vertical lugs 412 disposed at both ends of the crossbar 411. The movable plate 44 is slidably mounted on the vertical lugs 412. A stop hook 413 extends from the crossbar 411 toward the movable plate 44, and the stop hook 413 and the movable plate 44 form a locking space 45. The two ends of the first spring 42 and the second spring 43 are respectively connected to the movable plate 44 and the crossbar 411 to provide a restoring elastic force for the movable plate 44.

[0058] In this embodiment, the portal frame 41 is provided with mounting plates 415 at both ends of the horizontal bar 411 and on the outside of the vertical hanging lugs 412. Mounting holes 417 are provided on the mounting plates 415. The entire elastic buckle 4 is mounted to the lamp frame 201 of the lamp 200 by screws 46 through the mounting holes 417.

[0059] like Figure 11As shown, when the hook 3 is pressed into the elastic latch 4, the hook 3 is inserted into the locking space 45 between the moving plate 44 and the stop hook 413. During the insertion process, the hook 3 presses the moving plate 44, causing the moving plate 44 to move backward on the vertical lug 412, so that the hook 3 falls into the locking space 45. Then, the lamp 200 moves laterally to the rear, so that the stop hook 413 is embedded in the slot 32 and hooks the hook 3. At the same time, the moving plate 44 rebounds under the elastic force of the first spring 42 and the second spring 43, so that the gap between the moving plate 44 and the stop hook 413 is reduced or closed. In this way, the hook 3 and the elastic latch 4 will not disengage. At this time, the action of pressing the hook 3 into the elastic latch 4 and locking is completed.

[0060] Furthermore, in this embodiment, the movable plate 44 is tilted. For example... Figure 11 As shown, the movable plate 44 is set in an inclined state with its lower end close to the stop hook 413 and its upper end far away from the stop hook 413. In this way, when the hook 3 is pressed into the locking space 45 below the stop hook 413, it starts to guide, making it easy for the hook 3 to quickly engage with the elastic lock 4.

[0061] Preferably, in this embodiment, the vertical hanging ear 412 of the elastic buckle 4 is provided with a sliding groove 414, and the movable plate 44 is provided with two hanging holes 441. The vertical hanging ear 412 passes through the hanging hole 441, and the movable plate 44 is suspended on the sliding groove 414 of the vertical hanging ear 412. In this way, the movable plate 44 can slide back and forth in the sliding groove 414 of the vertical hanging ear 412, thereby completing the pressing and locking of the buckle 3.

[0062] In this embodiment, the crossbar 411 is also provided with a first spring hole 416 and the movable plate 44 is also provided with a second spring hole 442. The first spring hole 416 and the second spring hole 442 are respectively used to install the two ends of the first spring 42 or the second spring 43.

[0063] In embodiment two, this utility model also proposes a quick-installation device 100 for lamps (not shown), including a bracket 1, elastic latches 4 and a rotating seat 5 disposed at two opposite ends of the bracket 1, a rotating post 2 and a hook 3. The rotating seat 5 has a rotating hole 51. The rotating post 2 and the hook 3 can be disposed on two opposite sides of the lamp frame 201 of the lamp 200. The rotating post 2 on the lamp 200 is inserted into the rotating hole 51 of the rotating seat 5 and can rotate within the rotating hole 51. The hook 3 can be pressed into the elastic latches 4 and locked by the elastic latches 4.

[0064] The difference between Embodiment 2 and Embodiment 1 lies in the placement of the rotating column 2, hook 3, elastic latch 4, and rotating base 5. In Embodiment 1, the elastic latch 4 and rotating base 5 are mounted on the lamp fixture 200, while the rotating column 2 and hook 3 are mounted on the bracket 1. In Embodiment 2, the elastic latch 4 and rotating base 5 are mounted on the bracket 1, while the rotating column 2 and hook 3 are mounted on the lamp fixture 200. Since they have the same structure but different placement, Embodiment 2 can also be installed by connecting the lamp fixture 200 to the rotating latch. The installation device 100 in Embodiment 2 can also be operated by a single worker when installing the lamp fixture 200, making installation convenient, quick, and saving labor and time.

[0065] like Figures 3 to 5 As shown, this utility model also proposes a lamp 200, which includes the aforementioned quick-installation device 100. Due to the presence of the aforementioned quick-installation lamp 100, the lamp 200 of this utility model can be installed quickly and conveniently, making it suitable for the promotion and application of surface-mounted lamp products.
