[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example
[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a lamp frame locking structure is disposed between the lamp body 1 and the lamp frame 2, including an upper support bar 3, a lower support bar 4, at least two positioning pins 5, a locking screw 6, and at least two screws 7. The lamp body and lamp frame are conventional structures in the prior art. A light source plate 8 is fixed to the bottom surface of the lamp body, a light-transmitting panel 9 is disposed inside the lamp frame, and a mounting bracket 10 and a driving power supply 11 are disposed on the top surface of the lamp body. These are all conventional structures in the prior art and are therefore not described in detail. The lamp frame is a metal cover. The upper support bar is a metal profile; the lower support bar is an injection-molded support bar. Both ends of the locking screw are provided with a slotted groove or a cross-shaped groove. The lamp frame has operating holes 18 on both the top and bottom inner folded edges, which mate with the locking screws. The lamp body edge has clearance holes that mate with the operating holes. The locking screws can be tightened through the operating holes using a tool such as a screwdriver, or from below the lamp frame. Furthermore, the edge of the light-transmitting panel is held between the bottom surface of the lower support strip and the top surface of the bottom inner folded edge of the lamp frame.
[0030] During processing, the upper support bar is provided with two vertical screw holes 12 and one locking screw hole 13, with the locking screw hole located between the two vertical screw holes; simultaneously, the lower support bar is provided on the inner wall of the lamp frame, and its top surface is provided with two pin holes 14 with closed bottom ends and one fastening through hole 15, with the fastening through hole located between the two pin holes; during assembly, the edge of the lamp body and the inner folded edge of the top of the lamp frame are attached to the top surface of the upper support bar and fixed by two screws; the upper part of the positioning pin is located at the lower part of the vertical screw hole and the lower part of the positioning pin is inserted into the pin hole; the locking screw passes through the bottom end of the fastening through hole and is threadedly connected to the locking screw hole; when the locking screw is turned, the lower support bar moves downward and its bottom surface abuts against the inner folded edge of the bottom end of the lamp frame, and the top surface of the upper support bar abuts against the inner folded edge of the top end of the lamp frame and locks in place. It is achieved by having the top surface of the upper support bar and the bottom surface of the lower support bar abut against the inner folded edge at the top and bottom of the lamp frame, respectively, to lock the screws in place. This increases the contact area for screw locking and also ensures the stability of the overall structure, preventing loosening or displacement.
[0031] In this embodiment, an annular groove 16 is provided on the outer wall of the nut of the locking screw, and a soft rubber ring 17 is sleeved inside the annular groove. The outer ring surface of the soft rubber ring abuts against the inner wall of the fastening through hole. The soft rubber ring helps to fix the lower support bar and ensures the relative position of the locking screw and the lower support bar is stable. In actual application, the nut of the locking screw is a frustum-shaped nut with a smaller upper end and a larger lower end; the upper end of the nut has the same diameter as the screw of the locking screw. The bottom end of the nut of the locking screw is slightly larger than the inner diameter of the fastening through hole.
[0032] Furthermore, in this embodiment, the length of the positioning pin is less than the height of the vertical screw hole. The total height of the upper and lower support bars is less than the frame height of the lamp fixture. In this embodiment, the frame height of the lamp fixture is 40-70mm, which is a conventional structure in the prior art. The diameter of the positioning pin is the same as the diameter of the vertical screw hole and the diameter of the pin hole. This ensures the effectiveness of the positioning pin and does not affect the connection stability and reliability of the screw.
[0033] Compared with the prior art, the present invention has the following positive effects: The present invention includes an upper support bar, a lower support bar, at least two positioning pins, a locking screw, and at least two screws. The screws are used to attach and fix the top inner folded edge of the lamp body and the lamp frame. The advancement of the locking screw causes the upper support bar and the lower support bar to abut against the top inner folded edge and the bottom inner folded edge of the lamp frame, respectively, and lock them in place, ensuring the stability and effectiveness of the connection. Moreover, the positioning pins can guide the connection, improve the effectiveness of the relative translation of the lower support bar and the upper support bar, prevent tilting or shaking, reduce the difficulty of assembly, improve the efficiency of assembly, increase the contact area of the lamp frame, improve the strength of the overall structural connection, and solve the technical deficiency of the limited stability of the connection between the lamp body and the light-transmitting mask in the prior art.
[0034] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.
[0035] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
