Furthermore, the thickness of both supports matches the width of the inner folded edge of the top surface of the lamp frame. In practical applications, the width of the inner folded edge of the top surface of the lamp frame matches the width of the inner folded edge of the bottom surface of the lamp frame, or the width of the inner folded edge of the bottom surface of the lamp frame can be slightly larger than the width of the inner folded edge of the top surface of the lamp frame. The total height of the upper and lower support bars is less than the frame edge height of the lamp frame. This will not affect the installation and use of the light-transmitting panel, and the frame edge height of the lamp frame is 40-100mm. The edge of the light-transmitting panel 17 is clamped and limited between the lower support bar and the inner folded edge of the bottom end of the lamp frame.

[0031] The lower part of the round shaft is inserted into a vertical insertion hole, and a limiting pin is inserted into a radial pin hole at the lower part of the round shaft for positioning and is located on the bottom surface of the lower support bar; this limiting pin is located on the bottom surface of the lower support bar; the spring is sleeved on the round shaft, with the top end of the spring abutting against the bottom surface of the upper support bar and the bottom end abutting against the top surface of the lower support bar. A U-shaped clearance groove 18 is provided in the middle of the top surface of the upper support bar, and the limiting pin is located in the U-shaped clearance groove. This will not affect the effectiveness of the fit between the support bar and the top inner fold of the lamp frame.

[0032] During assembly, the edge of the lamp body and the inner folded edge of the top surface of the lamp frame are attached together, the top surface of the upper support strip is attached to the bottom surface of the inner folded edge of the top surface of the lamp frame, and two fixing screws are threaded into the mounting screw holes after passing through the edge of the lamp body and the inner folded edge of the top surface of the lamp frame; the elastic force of the spring causes the bottom edge of the lower support strip to abut against the top surface of the bottom inner folded edge of the lamp frame, and the top surface of the upper support strip abuts against the top inner folded edge of the lamp frame.

[0033] In practical applications, the upper part of the circular shaft is provided with an annular groove 14, and a rubber ring 15 is provided inside the annular groove; the circular shaft is connected to the vertical through hole through the rubber ring for damping. This can increase damping and prevent the central screw from detaching from the vertical through hole of the upper support bar.

[0034] Both the edge of the lamp body and the inner folded edge of the top surface of the lamp frame are provided with circular channels 16 that mate with the position of the round shaft. This facilitates the upward extension of the round shaft and is beneficial for the connection operation of the limiting pin.

During assembly, the upper support bar is fixed to the edge of the lamp body and the inner folded edge of the top surface of the lamp frame by the fixing screws, and the round shaft connects the upper support bar and the lower support bar. Under the elastic force of the spring, the lower support bar moves downward and the bottom surface of the lower support bar abuts against the inner folded edge of the bottom surface of the lamp frame. At the same time, the top surface of the upper support bar abuts against the inner folded edge of the top surface of the lamp frame. The upper and lower support bars increase the contact area with the lamp frame, and the edge of the lamp body fits against the inner folded edge of the top surface of the lamp frame, ensuring the stability of the connection between the lamp frame and the lamp body, increasing the contact area of ​​the lamp frame, improving the strength of the overall structure, and solving the technical deficiency of limited assembly stability in the prior art.

[0036] 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.

[0037] 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.
