This structure allows the lamp base to rotate, which is very convenient for people to rotate the lamp mounted on it in any horizontal direction, but it cannot guarantee whether the lamp base is secure.

[0004] Similarly, when the rotatable disc structure is applied to a lamp, the lamp is screwed to the lamp base, which cannot ensure whether the lamp is securely connected to the lamp. At the same time, when the lamp is screwed to the base, the screwing feedback is not obvious enough, and it is impossible to confirm whether the screwing is completed. Utility Model Content

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0037] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0038] like Figures 1 to 8As shown, a screw-on mounting structure 10 of an embodiment includes a base 100 and a lamp panel 200, the base 100 and the lamp panel 200 are screwed together, the screw-on mounting structure 10 also includes a clamping feedback spring 300 and a clamping point member 400, a screw groove 110 is opened on the base 100, and the screw groove 110 has a starting end 111 and an ending end 112; the clamping feedback spring 300 is arranged in the screw groove 110, and the clamping feedback spring 300 includes a mounting seat 310 and two elastic sheets 320 respectively arranged on the mounting seat 310, and the mounting seat 310 is arranged on the terminal end 112; the card point member 400 is used to enter the rotary groove 110 from the starting end 111, the card point member 400 includes a locking portion 410 and a limiting portion 420, the limiting portion 420 is arranged on the lamp panel 200, the locking portion 410 is arranged on the limiting portion 420, the limiting portion 420 is used to block the opening of the rotary groove 110 when the card point member 400 enters the terminal end 112 from the starting end 111, and the locking portion 410 is used to be locked into the two elastic sheets 320 when the card point member 400 enters the terminal end 112.

[0039] In this embodiment, combined with Figure 2 , Figures 5 to 8 As shown, the base 100 and the lamp panel 200 are rotatably arranged in the rotary groove 110 through the clamping point member 400 for fixing. Since the rotary installation structure 10 is provided with a clamping feedback elastic member 300, when the lamp panel 200 is clamped into the rotary groove 110 from the starting end 111 through the clamping point member 400, the limiting portion 420 is clamped to the inner wall of the rotary groove 110, and the clamping portion 410 is clamped into the two elastic sheets 320, so that the two elastic sheets 320 clamp the clamping portion 410. At this time, the clamping point member 400 is located at the terminal end 112, and the base 100 and the lamp panel 200 are firmly screwed together without loosening. In addition, when the When the lamp panel 200 is screwed and installed in one direction, the clamping point member 400 rotates from the starting end 111 to the ending end 112. During this period, the clamping portion 410 interacts with the two elastic sheets 320, and a feedback action occurs to clamp the clamping point member 400, so that the lamp panel 200 and the base 100 are firmly connected. When the lamp panel 200 is rotated in another direction for disassembly, the clamping portion 410 interacts with the two elastic sheets 320, and a feedback action occurs to move the clamping point member 400 from the ending end 112 to the starting end 111, thereby completing the disassembly of the lamp panel 200. Such a structure makes the rotation feedback effect better.

[0040] Furthermore, the number of the rotating groove 110 and the number of the clamping point members 400 are both multiple and equal, and each clamping point member 400 is respectively arranged correspondingly in the rotating groove 110, as shown in the effect diagram. Figure 2 and Figure 3 As shown, each clamping point member 400 is rotated from the starting end 111 to the ending end 112, and the limiting portion 420 is clamped to the inner wall of the rotation groove 110, and the clamping portion 410 is clamped into the two elastic sheets 320, thereby completing the operation of rotating the lamp panel 200 to be installed on the base 100.

[0041] In one of the embodiments, the cross-sectional diameter of the locking portion 410 is greater than the cross-sectional diameter of the limiting portion 420, so that when the limiting portion 420 is located in the rotation groove 110, the two elastic sheets 320 are ensured to clamp the locking portion 410. At the same time, under the action of the gravity of the lamp panel 200, the locking portion 410 will also abut against the mounting seat 310 to prevent the lamp panel 200 from falling.

[0042] like Figure 5 As shown in one embodiment, a snap-fit ​​groove 321 and a guide channel 322 are formed between the two elastic sheets 320, the snap-fit ​​groove 321 is communicated with the guide channel 322, and the guide channel 322 expands outwardly in a direction away from the snap-fit ​​groove 321, so that when the snap-fitting member 400 rotates from the starting end 111 to the ending end 112, the snap-fitting portion 410 passes through the guide channel 322 and is located in the snap-fit ​​groove 321, as shown in the effect diagram Figure 8 As shown. It can be understood that when the lamp panel 200 is screwed to the base 100 in one direction, the clamping point member 400 penetrates from the opening of the rotation groove 110 to the bottom of the rotation groove 110. During this period, the clamping part 410 interacts with the two elastic sheets 320 after passing through the guide channel 322. After the rotation feedback action occurs, the clamping part 410 is located in the clamping groove 321 and the two elastic sheets 320 clamp the clamping part 410; when the lamp panel 200 is rotated in another direction for disassembly, the clamping part 410 interacts with the two elastic sheets 320 to generate a rotation feedback action, and then the clamping part 410 passes through the guide channel 322 from the clamping groove 321, and then passes through the opening of the rotation groove 110 and moves away from the rotation groove 110, thereby completing the disassembly of the lamp panel 200. The guide channel 322 guides the clamping point member 400 to prevent the situation where the clamping cannot be engaged due to incorrect installation.

[0043] like Figure 5 As shown, in one embodiment, the mounting seat 310 is provided with an avoidance groove 311 and an avoidance channel 312, and the avoidance groove 311 is connected with the avoidance channel 312, so that when the clamping point member 400 is rotated from the starting end 111 to the ending end 112, the limiting portion 420 is located in the avoidance groove 311 after passing through the avoidance channel 312. It can be understood that when the lamp panel 200 is screwed to the base 100, the limiting portion 420 is always located on the inner wall of the rotation groove 110, and at the same time, part of the structure of the limiting portion 420 is located in the avoidance groove 311 after passing through the avoidance channel 312, wherein the avoidance channel 312 guides the limiting portion 420, and the avoidance groove 311 limits the limiting portion 420, so as to prevent the locking portion 410 from being located in the avoidance channel 312 and the avoidance groove 311. The effect diagram is shown in Figure 8 shown.

[0044] like Figure 6 and Figure 7As shown, in one embodiment, the base 100 is provided with an abutting groove 120, and the abutting groove 120 is arranged adjacent to the starting end 111. It can be understood that when the lamp panel 200 is rotated and installed on the base 100, the clamping portion 410 first abuts against the inner wall of the abutting groove 120 to prevent the clamping point member 400 from going deeper into the interior of the lamp panel 200 and causing the inability to rotate and connect, so that the clamping portion 410 smoothly enters the lamp panel 200 and reaches the clamping groove 321 after passing through the guide channel 322, so that the two elastic sheets 320 clamp the clamping portion 410, and the limiting portion 420 is always located on the inner wall of the rotating groove 110.

[0045] In this embodiment, there are a plurality of abutting grooves 120 , and each abutting groove 120 is disposed adjacent to a corresponding starting end 111 .

[0046] like Figure 3 and Figure 4 As shown, in one embodiment, the starting end 111 has a rounded corner area 111a, and the rounded corner area 111a is arranged between the side wall of the abutting groove 120 and the side wall of the rotating groove 110, wherein the rounded corner area 111a guides the limiting portion 420 to avoid the situation where the limiting portion 420 cannot enter the rotating groove 110 due to incorrect installation. It can be understood that after the engaging portion 410 abuts against the abutting groove 120, the engaging portion 410 enters the interior of the lamp panel 200 by rotating the lamp panel 200, and the limiting portion 420 transitions from the starting end 111 along the rounded corner area 111a to the terminal end 112, that is, the clamping point member 400 transitions from the starting end 111 to the terminal end 112 through the rounded corner area 111a to complete the rotation of the lamp panel 200 and the base 100.

[0047] like Figure 2 As shown, in one embodiment, the card point member 400 further includes a contact portion 430, which is disposed on the lamp panel 200, and the limit portion 420 is disposed on the contact portion 430, and the contact portion 430 is used to always contact the outer wall of the base 100 when the card point member 400 enters the terminal end 112. It can be understood that, in combination with Figure 3 , Figure 4 , Figures 6 to 10 As shown, when the card point member 400 is placed on the starting end 111 and rotated from the starting end 111 to the ending end 112, the abutment portion 430 abuts against the outer wall of the base 100 to prevent the locking portion 410 from going deeper into the base 100, thereby ensuring that the two elastic sheets 320 clamp the locking portion 410.

[0048] In one embodiment, the cross-sectional diameter of the abutment portion 430 is greater than the cross-sectional diameter of the limiting portion 420, thereby ensuring that the abutment portion 430 abuts against the outer wall of the base 100, and that the surface of the lamp panel 200 does not rub against the outer wall of the base 100 to damage the surface of the lamp panel 200 and the surface of the base 100.

[0049] The present disclosure also provides a screw-on ceiling lamp, comprising a light source (not shown), a driving member 11 and a screw-on mounting structure 10 of any of the above-mentioned embodiments, wherein the light source is mounted in a lamp panel 200, the driving member 11 is mounted in a base 100, and an electrical terminal of the driving member 11 is electrically connected to the light source.

[0050] Compared with the prior art, the present invention has at least the following advantages:

[0051] The above-mentioned screw-on installation structure 10 is provided with a clamping feedback spring 300. When the lamp panel 200 is inserted into the rotation groove 110 from the starting end 111 through the clamping point member 400, the limiting portion 420 is clamped to the inner wall of the rotation groove 110, and the clamping portion 410 is clamped into the two elastic sheets 320, so that the two elastic sheets 320 clamp the clamping portion 410. At this time, the clamping point member 400 is located at the terminal end 112, and the screw connection between the base 100 and the lamp panel 200 is more secure and will not loosen. In addition, when the lamp panel 200 is screwed and installed, The card point piece 400 rotates from the starting end 111 to the ending end 112, during which the locking portion 410 interacts with the two elastic sheets 320, and a feedback action occurs to clamp the card point piece 400, so that the lamp panel 200 and the base 100 are firmly connected. When the lamp panel 200 needs to be disassembled, the locking portion 410 interacts with the two elastic sheets 320, and a feedback action occurs to move the card point piece 400 from the ending end 112 to the starting end 111, thereby completing the disassembly of the lamp panel 200. Such a structure makes the rotation feedback effect better.

[0052] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the disclosed patent shall be subject to the attached claims.
