[0005] 2. Technical Solution

[0006] In order to solve the above technical problems, the present invention provides a downlight structure that can be replaced by pressing, including a lampshade and a wick arranged therein, the lampshade has a support for installing the wick; a rotating ring is also rotatably provided on the support, and a first ring sleeve is provided on the rotating ring. A second ring sleeve is provided at the opening position of the lampshade corresponding to the first ring sleeve, and the wick is fixedly arranged in the second ring sleeve, and a spring sleeved on the rotating ring is connected between the first ring sleeve and the support, and the surface of the first ring sleeve has a ring groove for fixing the spring, the inner ring of the first ring sleeve has a plurality of plug-in parts evenly distributed along its circumferential direction, the outer ring of the rotating ring has a clamping part corresponding to the plug-in part, the inner ring of the second ring sleeve has a plurality of pressing parts evenly distributed along its circumferential direction, and the outer ring of the rotating ring also has a lap part corresponding to the pressing part.

[0007] Among them, the first ring sleeve is provided with a third ring sleeve which is sleeved on the rotating ring, the third ring sleeve is fixedly connected to the support, and the rotating ring is rotatably arranged in the third ring sleeve. The peripheral wall of the third ring sleeve corresponds to the position of each plug-in part and is provided with a first strip opening extending along the axial direction of the third ring sleeve and for the plug-in part to be inserted into. The peripheral wall of the third ring sleeve corresponds to the position of each pressing part and is also provided with a second strip opening extending along the axial direction of the third ring sleeve and for the pressing part to be inserted into.

[0008] Among them, the end surface of the first ring sleeve corresponding to the second ring sleeve is evenly distributed with a number of triangular plugs along its circumferential direction, and the end surface of the second ring sleeve corresponding to the second ring sleeve is provided with a triangular slot matched with each triangular plug.

[0009] The clamping portion is provided with a first protrusion and a second protrusion protruding from the outer ring of the rotating ring, the plug-in portion is provided with an extension block, and a clamping slot for inserting the extension block is formed between the first protrusion and the second protrusion.

[0010] Among them, the overlapping part is provided with a first corrugated groove opened on the outer ring of the rotating ring, the pressing part is provided with an extension column, the end face of the rotating ring facing the first ring sleeve and corresponding to each extension column are provided with a through-hole for it to penetrate into the first corrugated groove, and the overlapping part is also provided with a second corrugated groove opened on the outer ring of the rotating ring and corresponding to the first corrugated groove, the second corrugated groove is close to the through-hole, and the second corrugated groove and the first corrugated groove form an integrated corrugated groove surrounding the rotating ring and connected to the through-hole.

[0011] The support is provided with a fixed ring which is sleeved in the rotating ring, and the end surface of the second ring sleeve facing the first ring sleeve is provided with a docking ring which can be sleeved on the fixed ring.

[0012] Among them, an electrical connection seat is provided in the middle of the support, and an electrical plug-in terminal is provided in the middle of the second ring sleeve, and the electrical connection seat can be electrically connected and matched with the electrical plug-in terminal.

[0013] The first corrugated groove is provided with a first inclined surface and a first top groove in a continuous and alternating manner, and the second corrugated groove includes a second inclined surface, a third inclined surface and a receiving groove;

[0014] When the wick is installed, the spring is compressed, the extension column enters through the through-hole and abuts against the first inclined surface, causing the rotating ring to rotate until the extension column abuts against the first top groove. At this time, the spring is no longer compressed. Under the action of the spring elastic force, the extension column first abuts against the second inclined surface, causing the rotating ring to rotate until the extension column enters the receiving groove, thereby completing the installation of the wick;

[0016] 3. Beneficial Effects

[0017] Compared with the prior art, the present invention can replace the wick by pressing. Specifically, since the first ring sleeve and the support are connected by a spring, the pressing part on the second ring sleeve is prompted to cooperate with the overlapping part on the rotating ring. Pressing once causes the pressing part to be stuck in the overlapping part, thereby completing the fixation of the second ring sleeve and the rotating ring. Pressing again causes the pressing part to be separated from the overlapping part, thereby completing the separation of the second ring sleeve and the rotating ring, thereby realizing the replacement of the wick, improving the replacement speed, and facilitating disassembly.

[0018] Furthermore, by the arrangement of the third ring sleeve, the rotating ring is restricted in the third ring sleeve and the support, and the rotating ring can only rotate therein relative to the third ring sleeve. Since the plug-in portion on the first ring sleeve and the pressing portion on the second ring sleeve are respectively movably clamped in the first strip opening and the second strip opening, the first ring sleeve and the second ring sleeve can both move linearly along the axial direction of the third ring sleeve, thereby achieving movable guidance of the first ring sleeve and the second ring sleeve, maintaining the correspondence between the plug-in portion and the clamping portion, and maintaining the correspondence between the pressing portion and the overlapping portion, thereby ensuring the cooperation and fixation of the second ring sleeve and the rotating ring; through the fit between the triangular plug block on the first ring sleeve and the triangular slot on the second ring sleeve, the second ring sleeve is able to adaptively fit completely with the first ring sleeve, maintaining the pressing portion on the second ring sleeve corresponding to the second strip opening on the third ring sleeve, achieving the cooperation between the pressing portion and the overlapping portion, facilitating the docking of the second ring sleeve and the rotating ring, and improving the fixing efficiency of the second ring sleeve and the rotating ring.

[0041] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention. Example

[0042] See also Figures 1-11 As shown, a downlight structure that can be replaced by pressing includes a lampshade 1 and a wick 2 arranged therein, and the lampshade 1 has a support 3 for installing the wick 2; a rotating ring 4 is also rotatably provided on the support 3, and a first ring sleeve 5 is sleeved on the rotating ring 4. The opening position of the lampshade 1 is provided with a second ring sleeve 6 corresponding to the first ring sleeve 5, and the wick 2 is fixedly arranged in the second ring sleeve 6. A spring 7 sleeved on the rotating ring 4 is connected between the first ring sleeve 5 and the support 3, and the surface of the first ring sleeve 5 has an annular groove 51 for fixing the spring 7, the inner ring of the first ring sleeve 5 has a plurality of plug-in parts 52 evenly distributed along its circumferential direction, the outer ring of the rotating ring 4 has a clamping part 41 corresponding to the plug-in part 52, the inner ring of the second ring sleeve 6 has a plurality of pressing parts 61 evenly distributed along its circumferential direction, and the outer ring of the rotating ring 4 has a lap part 42 corresponding to the pressing part 61.

[0043] When the wick 2 is not installed, the second ring sleeve 6 is separated from the first ring sleeve 5, the spring 7 is in a normal state, and the plug-in portion 52 on the first ring sleeve 5 is clamped in the corresponding clamping portion 41 on the rotating ring 4. At this time, the rotating ring 4 cannot rotate relative to the first ring sleeve 5;

[0044] When the wick 2 is ready to be installed, the installer fixes the wick 2 in the second ring sleeve 6, and then presses the second ring sleeve 6 into the lampshade 1 corresponding to the first ring sleeve 5. As the second ring sleeve 6 is continuously pressed, the first ring sleeve 5 moves relative to the rotating ring 4 toward the support 3, and the rotating ring 4 does not move with the first ring sleeve 5. The spring 7 is in a compressed state. At this time, the plug-in portion 52 on the first ring sleeve 5 is separated from the corresponding clamping portion 41, and at the same time as the plug-in portion 52 is separated from the clamping portion 41, the pressure on the second ring sleeve 6 is released. The portion 61 enters the overlapping portion 42 on the rotating ring 4. As the second ring sleeve 6 continues to penetrate deeper into the lampshade 1, the pressing portion 61 cooperates with the overlapping portion 42 to cause the rotating ring 4 to rotate relative to the first ring sleeve 5. Then, the installer loosens the second ring sleeve 6, and the spring 7 returns to its normal state, causing the first ring sleeve 5 to drive the second ring sleeve 6 to pop out toward the opening direction of the lampshade 1. At this time, the pressing portion 61 is stuck on the overlapping portion 42, and the second ring sleeve 6 is stuck on the rotating ring 4 in contact with the first ring sleeve 5, completing the installation of the wick 2.

[0045] When the wick 2 is replaced, it is only necessary to press the second ring sleeve 6 again to cause the rotating ring 4 to rotate again, and the pressing portion 61 will disengage from the overlapping portion 42, thereby releasing the fixation between the second ring sleeve 6 and the rotating ring 4. At this time, the plug-in portion 52 on the first ring sleeve 5 will be re-engaged in the clamping portion 41 on the rotating ring 4, keeping the rotating ring 4 from rotating relative to the first ring sleeve 5 when the wick 2 is not installed.

[0046] See also Figure 6 、 Figure 10 and Figure 11 As shown, the first ring sleeve 5 is provided with a third ring sleeve 8 which is sleeved on the rotating ring 4. The third ring sleeve 8 is fixedly connected to the support 3. The rotating ring 4 is rotatably set in the third ring sleeve 8. The peripheral wall of the third ring sleeve 8 corresponds to the position of each plug-in portion 52 and is provided with a first strip opening 81 extending along the axial direction of the third ring sleeve 8 and for the plug-in portion 52 to be snapped into. The peripheral wall of the third ring sleeve 8 corresponds to the position of each pressing portion 61 and is also provided with a second strip opening 82 extending along the axial direction of the third ring sleeve 8 and for the pressing portion 61 to be snapped into.

[0047] When the second ring sleeve 6 is pressed into the depth of the lampshade 1 in contact with the first ring sleeve 5, the spring 7 set on the third ring sleeve 8 is compressed, and the plug-in portion 52 on the first ring sleeve 5 moves in the first strip opening 81 on the third ring sleeve 8, thereby disengaging from the clamping portion 41 on the rotating ring 4, and the pressing portion 61 on the second ring sleeve 6 enters the second strip opening 82 on the third ring sleeve 8 and moves along the second strip opening 82. At this time, the pressing portion 61 is in contact with the overlapping portion 42, which prompts the rotating ring 4 to rotate in the third ring sleeve 8 until the second ring sleeve 6 is pressed After it is in place, relax the second ring sleeve 6. Under the action of the spring 7, the second ring sleeve 6 pops outward to the position where the spring 7 restores the state. At this time, the pressing portion 61 contacts the overlapping portion 42 again, and the pressing portion 61 is stuck on the overlapping portion 42. The second ring sleeve 6 is positioned on the rotating ring 4, completing the installation of the wick 2. On the contrary, when disassembling, press the second ring sleeve 6 again to cause the rotating ring 4 to rotate, and the pressing portion 61 is separated from the overlapping portion 42. At this time, the second ring sleeve 6 and the wick 2 can be separated from the first ring sleeve 5, completing the disassembly of the wick 2.

[0048] See also Figure 7-11 As shown, the end surface of the first ring sleeve 5 corresponding to the second ring sleeve 6 has a plurality of triangular inserts 53 evenly distributed along its circumferential direction, and the end surface of the second ring sleeve 6 corresponding to the second ring sleeve 6 has a triangular slot 62 matched with each triangular insert 53.

[0049] When the second ring sleeve 6 is pressed against the first ring sleeve 5, since the first ring sleeve 5 has a triangular plug block 53, and the second ring sleeve 6 has a triangular slot 62 that fits with the triangular plug block 53, as the second ring sleeve 6 is pressed against the first ring sleeve 5, the triangular slot 62 on the second ring sleeve 6 will automatically correspond to the triangular plug block 53 on the first ring sleeve 5, so that the first ring sleeve 5 and the second ring sleeve 6 are completely fitted together. As the second ring sleeve 6 is continuously pressed, the pressing portion 61 on the second ring sleeve 6 can enter the corresponding second strip opening 82 on the third ring sleeve 8, thereby entering the corresponding overlapping portion 42 on the rotating ring 4 and cooperating with it, driving the rotation of the rotating ring 4, and finally prompting the pressing portion 61 to be stuck on the overlapping portion 42, completing the fixation of the second ring sleeve 6 and the rotating ring 4.

[0050] See also Figure 9 As shown, the clamping portion 41 is provided with a first protrusion 411 and a second protrusion 412 protruding from the outer ring of the rotating ring 4, and the plug-in portion 52 is provided with an extension block 521. A clamping slot for inserting the extension block 521 is formed between the first protrusion 411 and the second protrusion 412.

[0051] When the spring 7 is in a normal state, the extension block 521 on the first ring sleeve 5 is stuck in the groove formed between the corresponding first protrusion 411 and the second protrusion 412. At this time, the rotating ring 4 cannot rotate relative to the third ring sleeve 8, and the overlapping portion 42 on the rotating ring 4 also corresponds to the second strip-shaped opening 82 on the third ring sleeve 8, which facilitates the docking of the pressing portion 61 on the second ring sleeve 6 with the overlapping portion 42. As the second ring sleeve 6 is pressed, the extension block 521 on the first ring sleeve 5 is separated from the first protrusion 411 and the second protrusion 412. At this time, the rotating ring 4 can rotate relative to the third ring sleeve 8. After the contact between the pressing portion 61 and the overlapping portion 42 is made, the rotating ring 4 is rotated, the second ring sleeve 6 is relaxed again, the spring 7 returns to its normal state, and the cooperation between the pressing portion 61 and the overlapping portion 42 causes the pressing portion 61 to be stuck on the overlapping portion 42, and the second ring sleeve 6 is then positioned on the rotating ring 4. When the second ring sleeve 6 is pressed again, the pressing portion 61 is separated from the overlapping portion 42, and the second ring sleeve 6 can be separated from the rotating ring 4. At this time, the extension block 521 on the first ring sleeve 5 is re-stuck in the first protrusion 411 and the second protrusion 412, maintaining the positioning of the rotating ring 4, which is conducive to the second ring sleeve 6 and the rotating ring 4 docking again.

[0052] See also Figure 8 As shown, the overlapping portion 42 is provided with a first corrugated groove 421 opened on the outer ring of the rotating ring 4, the pressing portion 61 is provided with an extension column 611, and the end surface of the rotating ring 4 facing the first ring sleeve 5 and corresponding to each extension column 611 are provided with a through-hole 422 for it to penetrate into the first corrugated groove 421. The overlapping portion 42 is also provided with a second corrugated groove 423 opened on the outer ring of the rotating ring 4 and corresponding to the first corrugated groove 421. The second corrugated groove 423 is close to the through-hole 422, and the second corrugated groove 423 and the first corrugated groove 421 form an integrated corrugated groove surrounding the rotating ring 4 and connected to the through-hole 422.

[0053] When the extension column 611 on the second ring sleeve 6 enters the second strip-shaped opening 82 on the third ring sleeve 8, as the pressure is continued, the extension column 611 enters the first corrugated groove 421 through the through-opening 422. As the extension column 611 presses against the first corrugated groove 421, the rotation of the rotating ring 4 is promoted under the slope of the first corrugated groove 421. At this time, the through-opening 422 deviates from the extension column 611. As the second ring sleeve 6 is loosened, the extension column 611 moves away from the first corrugated groove 421 and then aligns with the second corrugated groove 421. The second ring sleeve 6 is fixed to the rotating ring 4. When the second ring sleeve 6 is pressed again, the extension column 611 moves away from the second corrugated groove 423 and contacts the first corrugated groove 421 again. The extension column 611 presses the first corrugated groove 421, and the rotating ring 4 is rotated again. At this time, the through-hole 422 is facing the extension column 611. As the second ring sleeve 6 is loosened, the extension column 611 detaches from the through-hole 422, and the second ring sleeve 6 is taken out.

[0054] See also Figure 6 As shown, the support 3 has a fixed ring 31 sleeved in the rotating ring 4 , and the end surface of the second ring sleeve 6 facing the first ring sleeve 5 has a docking ring 63 that can be sleeved on the fixed ring 31 .

[0055] When the second ring sleeve 6 is docked with the rotating ring 4, the docking ring 63 on the second ring sleeve 6 is sleeved on the fixed ring 31 on the support 3, indicating that the second ring sleeve 6 is accurately docked on the rotating ring 4. Otherwise, the second ring sleeve 6 deviates from the center point and cannot be docked on the rotating ring 4.

[0056] Specifically, the first corrugated groove 421 is continuously and alternately provided with a first inclined surface 4211 and a first top groove 4212. The second corrugated groove 423 includes a second inclined surface 4231, a third inclined surface 4232 and a receiving groove 4233. In the second corrugated groove 423, the second inclined surface 4231, the receiving groove 4233, the third inclined surface 4232 and the through-opening 422 are continuously and alternately provided.

[0057] When the wick 2 is installed, the spring 7 is compressed, and the extension column 611 enters through the through-hole 422 and abuts against the first inclined surface 4211, causing the rotating ring 4 to rotate until the extension column 611 abuts against the first top groove 4212. At this time, the spring 7 is no longer compressed. Under the elastic force of the spring 7, the extension column 611 first abuts against the second inclined surface 4231, causing the rotating ring 4 to rotate until the extension column 611 enters the receiving groove 4233, thereby completing the installation of the wick 2.

[0058] When the wick 2 is disassembled, the spring 7 is compressed, the extension column 611 disengages from the receiving groove 4233 and abuts against the first inclined surface 4211 to rotate the rotating ring 4 until the extension column 611 abuts against the first top groove 4212. At this time, the spring 7 is no longer compressed. Under the action of the elastic force of the spring 7, the extension column 611 disengages from the through-hole 422 along the third inclined surface 4232, thereby realizing the disassembly of the wick 2.

[0059] The present invention uses a pressing method. Since the first ring sleeve 5 and the support 3 are connected by a spring 7, the pressing portion 61 on the second ring sleeve 6 is forced to cooperate with the overlapping portion 42 on the rotating ring 4. When pressed once, the pressing portion 61 is stuck in the overlapping portion 42, and the second ring sleeve 6 and the rotating ring 4 are fixed. When pressed again, the pressing portion 61 is separated from the overlapping portion 42, and the second ring sleeve 6 and the rotating ring 4 are separated, which improves the replacement speed and facilitates disassembly. Example

[0060] Compared with Example 1, in this embodiment, an electrical connection seat 32 is provided in the middle of the support 3, and an electrical plug-in terminal 64 is provided in the middle of the second ring sleeve 6. The electrical connection seat 32 can be electrically connected and cooperated with the electrical plug-in terminal 64. The electrical connection seat 32 and the electrical plug-in terminal 64 are both ring-shaped, thereby realizing the circuit connection of the downlight in this embodiment.

[0061] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
