DETAILED DESCRIPTION

[0048] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0049] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0050] In one embodiment of the present invention, a rotating assembled lamp is provided, such as Figures 1 to 3As shown, the lamp includes a lampshade 100 and a bottom shell 200, on which a lamp board 350, a control module, a drive module, etc. (not shown) of the lampshade 100 and the bottom shell 200 are mounted. One of the lampshade 100 and the bottom shell 200 is provided with an arcuate groove 310, and the other is provided with a buckle 320 that cooperates with the arcuate groove 310. The following takes the arcuate groove 310 provided on the bottom shell 200 and the buckle 320 provided on the lampshade 100 as an example to illustrate the structure of the bottom shell 200 and the lampshade 100 being fixedly connected without any fixing parts other than the lampshade's own structure. It should be noted that, conversely, the arcuate groove 310 provided on the lampshade 100 and the buckle 320 provided on the bottom shell 200 can also achieve a fixed connection between the two without any fixing parts other than the lampshade's own structure.

[0051] like Figure 3 and Figure 4 As shown, the buckle 320 has a free end 322 and a fixed end 321 fixed on the wall;

[0052] like Figure 7 and Figure 8 As shown, the arc-shaped groove 310 is provided with a first step 311, a second step 312 and a receiving portion 313 located between the first step 311 and the second step 312. The channel width corresponding to the receiving portion 313 is greater than the channel width at the first step 311.

[0053] The lamp has a disassembled state and an assembled state. In the disassembled state, the buckle 320 is separated from the arc groove 310; in the assembled state, Figure 8 As shown, after the free end 322 passes through the first step 311, the buckle 320 is accommodated in the accommodating portion 313, and the free end 322 is deformed when passing through the first step 311, that is, the channel width at the first step 311 is not enough to allow the free end 322 to pass through without deformation. Since the corresponding channel width at the accommodating portion 313 is larger than the channel width at the first step 311, when the free end 322 enters the accommodating portion 313, the deformation amount becomes smaller and the free end 322 is pressed against the connecting surface between the first step 311 and the accommodating portion 313. At this time, the buckle 320 cannot be screwed out of the arc groove 310 in the opposite direction of the screw-in direction. Figure 8 As shown, a first guide slope 3111 is provided at the first step 311, and a second guide slope 323 is provided at the buckle 320. Figure 4 、 Figure 8 、 Figure 10As shown, in the process of screwing the buckle 320 into the arc groove 310, when the buckle 320 reaches the first step 311, the second guide bevel 323 cooperates with the first guide bevel 3111 to allow the buckle 320 to pass through the first step 311 smoothly and be snapped into the accommodating portion 313.

[0054] like Figure 11 and Figure 12 As shown, a through hole 314 is provided on the outer wall of the accommodating portion 313. In the assembled state, the through hole 314 is arranged opposite to the free end 322 of the buckle 320. The function of the through hole is to unlock the lampshade 100 and the bottom shell 200: a rigid strip-shaped object is inserted into the through hole 314 to poke the free end 322 of the buckle 320 to separate it from the first step 311. At this time, if it is reversed, the buckle 320 can be rotated out of the arc groove 310.

[0055] like Figures 3 to 6 As shown, the other of the lampshade 100 and the bottom shell 200 provided with the buckle 320 is further provided with a limiting member 330, and one end of the limiting member 330 is a limiting end 331 provided adjacent to the free end 322 of the buckle 320;

[0056] The limiting end 331 is provided with a first inclined surface;

[0057] The buckle 320 and the limiting member 330 have two positional relationships. The first positional relationship is as follows: Figure 4 As shown, in the absence of external force, the two are separated;

[0058] The second position relationship is Figure 4 Transformed into Figure 6 When an external force acts on the free end 322, the free end 322 moves along the first inclined surface of the limiting end 331 in a direction away from the first step 311 until the free end 322 passes the first inclined surface and abuts against the side of the limiting end 331 away from the first step 311. The limiting member 330 is provided so that after a force is applied to the free end 322 through the through hole 314, the limiting member 330 can be used to keep the free end 322 separated from the first step 311. Even if the force applied through the through hole 314 is removed, the free end 322 is still not obstructed by the first step 311.

[0059] In addition to the above embodiment of providing the through hole 314 on the circumferential outer wall of the accommodating portion 313, another embodiment can be used to unlock the lampshade 100 and the bottom shell 200: Figure 1 、 Figure 2 、 Figure 11 and Figure 12As shown, an unlocking hole 230 is provided on the side wall of the arc-shaped groove 310. After the disassembly tool passes through the unlocking hole 230, it is inserted between the buckle 320 and the bottom of the arc-shaped groove 310. The thickness of the disassembly tool is greater than the width of the gap between the buckle 320 and the bottom of the arc-shaped groove 310, so that the free end 322 of the buckle 320 moves away from the bottom of the groove until the free end 322 passes through the first inclined surface and is pressed against the side of the limit end 331 away from the first step 311.

[0060] like Figure 6 As shown, the other end of the limiter 330 is an operable portion 332 that is suspended. The operable portion 332 is configured to approach the other end under the action of an external force so that the limiter end 331 has a tendency to release the free end 322 that is against the limiter end 331. Specifically, after the lampshade 100 is reversely rotated to separate it from the bottom shell 200, before the next assembly, the operable portion 332 is pressed downward to change the positional relationship between the two. Figure 6 Restore to Figure 4 .

[0061] In addition to applying force to the operable portion 332 of the limiting member 330, automatic separation can also be achieved by designing a mechanical structure: Figure 11 and Figure 12 A protrusion 370 is provided on the bottom shell 200, and its function is as follows: when the buckle 320 and the limiting member 330 are Figure 6 When the state of the retaining member 330 is rotated out of the arc groove 310, the protrusion 370 generates a force on the front of the operable portion 332 of the limiting member 330. When the operable portion 332 moves in a direction away from the bottom of the groove, the other end of the limiting member 330 tends to approach the bottom of the groove, and then the buckle 320 is disengaged, and the other end of the limiting member 330 makes the positional relationship between the two return to the state before the arc groove 310 is rotated out. Figure 4 status.

[0062] Depend on Figure 4 It can be seen that the free end 322 has a second inclined surface opposite to the first inclined surface, and the second inclined surface is connected to a step surface;

[0063] Depend on Figure 6 It can be seen that after the free end 322 passes through the first inclined surface under the action of external force, the step surface abuts against the limiting end 331 .

[0064] See also Figure 4 、 Figure 7 The other of the lampshade 100 and the bottom shell 200 having the buckle 320 is further provided with a guide bar 340 . In the assembled state, the guide bar 340 is at least partially accommodated in the arc groove 310 .

[0065] In one embodiment, in the assembled state, the fixed end 321 of the buckle 320 abuts against the second step 312. Figure 7 and Figure 8 As shown, to prevent the buckle 320 from moving in the arc groove 310;

[0066] In one embodiment, the guide bar 340 is provided with a protrusion 341 at one end away from the buckle 320; in the assembled state, the protrusion 341 is pressed against to prevent the buckle 320 from moving in the arc groove 310. Figure 7 and Figure 8 As shown, these two embodiments of preventing the buckle 320 from moving in the arc-shaped slot 310 can coexist.

[0067] like Figure 7 and Figure 9 As shown, the number of the guide bars 340 is multiple;

[0068] In a specific embodiment, the number of the buckle 320 is one. In this case, the lamp can be provided with an anti-fool structure: Figure 10 As shown, only one guide bar 340 is provided with an anti-fouling joint 342, and correspondingly, the arc-shaped groove 310 is provided with an anti-fouling interface 315 that cooperates with the anti-fouling joint 342, as shown in FIG. Figure 11 and Figure 12 shown.

[0069] In addition to the lampshade 100 and the bottom shell 200, the lamp also includes a connecting ring 360, which surrounds the outer edges of the lampshade 100 and the bottom shell 200, enhancing the lamp's aesthetics. A sealing ring can be provided on the connecting ring 360 to ensure the lamp meets outdoor waterproofing requirements. In this embodiment, the connecting ring is provided on the lampshade 100. Specifically, a snap-fit block 101 is provided on the lampshade 100, and a snap-fit groove 360 is provided on the connecting ring 360 to achieve a snap-fit connection between the two. Again, no external fixings are required.

[0070] Considering that the buckle 320 that allows deformation is generally made of plastic, and plastic parts have a long or short service life, in one embodiment, a screw hole 210 is reserved at an appropriate position on the bottom shell 200, such as Figure 1 、 Figure 2 、 Figure 11 and Figure 12 As shown, when necessary (such as when the plastic part is aging), install the screw 220 at the screw hole 210, as shown in FIG. Figure 7 and Figure 8 As shown, at this time, the screw 220 just abuts against the guide bar 340 screwed into the arc groove 310. In this way, even if the buckle 320 fails, the screw 220 can prevent the lampshade 100 from separating from the bottom shell 200.

[0071] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.

[0072] The above is only a specific implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
