[0028] Reference Figures 1-4 As shown, a panel light with adjustable lamp tube angle includes...

[0029] Housing 10, lamp body 20, and mounting structure,

[0030] A movable adjustment structure is provided on the outer wall of the lamp body 20; the movable adjustment structure includes a connecting rod 200, a crossbar 202 provided at one end of the connecting rod 200, and main tooth plates 204 provided at both ends of the crossbar 202.

[0031] The mounting structure includes a connection structure that adjusts and engages with the main toothed plate 204; the connection structure includes an arc-shaped plate 40 and a horizontal plate 400, a groove 402 formed on the arc-shaped plate 40, an inner groove 404 symmetrically formed in the groove 402, and a secondary toothed plate 406 disposed in the inner groove 404 and connected to the main toothed plate 204; thus, by adjusting the main toothed plate 204 and the secondary toothed plate 406, the lamp body 20 can slide left and right on the arc-shaped plate 40, giving the lamp body 20 a certain angle adjustment capability.

[0032] In one embodiment, the main tooth plate 204 and the auxiliary tooth plate 406 adopt asymmetrical trapezoidal teeth (such as one side of the tooth surface with an inclination angle of 60° and the other side with 30°), which makes it easier to push in one direction and more stable to self-lock in the reverse direction.

[0033] A connecting piece is symmetrically provided at one end of the horizontal plate 400; the connecting piece includes a plug plate 408 provided on the horizontal plate 400, and an inward recess 410 formed at one end of the plug plate 408; a locking rod 412 is provided on the outer side of the other end of the plug plate 408.

[0034] In one embodiment, an elastic steel ball is added to the end of the locking lever 412 (which engages with the recess in the locking groove 5032), and a "click" sound indicates that it has been inserted.

[0035] The top of the housing 10 is symmetrically formed with mounting grooves 50 for mounting lamp body 20, and strip grooves 500 symmetrically formed on both sides of the mounting grooves 50. A snap-fit ​​member is provided at both ends of the strip grooves 500 and connected to the mating member. The snap-fit ​​member includes mounting blocks 5020, a round rod 5024 disposed between the two mounting blocks 5020, a sleeve plate 5022 sleeved on the round rod 5024, springs 5026 disposed on both sides of the sleeve plate 5022 and sleeved on the round rod 5024, a pressing seat 5028 disposed at one end of the spring 5026, and an arc-shaped portion 50280 formed at one end of the pressing seat 5028.

[0036] Among them, the spring 5026 adopts a variable pitch design (dense coils at both ends provide initial preload, while sparse coils in the middle adapt to large displacement), avoiding excessive tightness that would cause difficulty in insertion and removal.

[0037] One end of the mounting block 5020 is provided with a ramp 5030, forming a locking groove 5032 at one end of the ramp 5030.

[0038] The horizontal plate 400 is also provided with a snap-fit ​​plate 60, forming a snap-fit ​​groove 602 at one end of the snap-fit ​​plate 60; a protrusion 70 for connecting with the snap-fit ​​groove 602 is provided at the middle position of the opening of the strip groove 500.

[0039] In one embodiment, the slot 602 is embedded with a U-shaped spring, and the protrusion 70 is hemispherical. When fastened, the spring deforms to generate a continuous clamping force. The snap-fit ​​plate 60 is made of transparent material and has an LED light inside (connected to the circuit). When the fastening is successful, the light changes color to indicate that the fastening is successful.

[0040] Working principle:

[0041] Angle adjustment is achieved through the movable adjustment structure on the outer wall of the lamp body 20. The connecting rod 200 drives the main toothed plates 204 at both ends of the crossbar 202 to mesh with the auxiliary toothed plates 406 in the mounting structure. When the lamp body 20 is pushed, the main toothed plates 204 slide along the inner groove 404 of the arc-shaped plate 40. Through the meshing transmission between the toothed plates, the lamp body 20 swings left and right along the arc trajectory to achieve stepless angle adjustment. After adjustment, the friction between the toothed plates maintains angle stability. During installation, the insertion plates 408 at both ends of the crossbar 400 are inserted into the strip groove 500 of the mounting groove 500 of the housing 10. The inner recess 410 of the insertion plates 408 guides them to slide in and compresses the pressing seat 5028 pushed by the spring 5026. When the insertion plates... After 408 is fully inserted, its outer locking rod 412 engages in the locking groove 5032 of the inclined plate 5030. At the same time, the spring 5026 rebounds, causing the arc-shaped part 50280 of the pressing seat 5028 to press tightly against the plug-in plate 408 to form a two-way clamping fixation. The locking plate 60 on the horizontal plate 400 is further prevented from falling out by engaging with the protrusion 70 in the middle of the strip groove 500 through the locking groove 602. This achieves quick installation and stable fixation. When disassembling, pressing the pressing seat 5028 to overcome the spring force will allow the locking rod 412 to disengage from the locking groove 5032 and the plug-in plate 408 to be pulled out. The entire structure achieves convenient installation, flexible adjustment and reliable fixation through the coordinated design of toothed plate meshing adjustment and plug-in buckle fixation.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
