Description

Technical Field

[0001] The present disclosure relates to the field of lighting technology, and in particular to a downward-pressed, fastened grille structure and a rotating grille lamp. Background Art

[0002] Lighting fixtures are widely used in daily life. Different lamps are used in different occasions, and the lighting atmosphere and effects are different. Some companies have considered the issue of adjusting the lighting angle of lighting fixtures, and some lamps with adjustable lighting angles have appeared on the market.

[0003] For example, the existing patent CN211232801U discloses a magnetic guide rail grille lamp installation structure, which includes an electrical box, a connection box and a lamp body, wherein a hexagonal cylindrical head screw passes through the right bearing, the shaft hole, the left bearing in sequence and is fastened with a lock nut, so that the lamp body can rotate vertically along the connecting axis.

[0004] However, when the structure rotates vertically, the left and right bearings rotate along with it. After multiple vertical rotations, the anti-loosening nut may rotate along with it under the action of the left bearing, causing the hexagonal cylindrical head and the anti-loosening nut to loosen. In this way, when the structure rotates vertically, due to its own gravity, the lamp body slowly faces the ground and cannot illuminate stably at any angle. Utility Model Content

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this disclosure pertains. The terms used herein in the specification of this disclosure are intended only to describe specific embodiments and are not intended to limit this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0037] like Figure 1 As shown, it is a downward pressing and fastening grille structure 10 according to an embodiment of the present invention, comprising a power connection module 100 , a rotating bracket 200 and a lamp body 300 .

[0038] The power connection module 100 is used to connect to an external power rail. In this embodiment, a side wall of the power connection module 100 is provided with a fastener 101. The power connection module 100 is fastened to the external power rail through the fastener 101. The fastener 101 is fastened to the side of the external power rail to fix the power connection module 100 to the external power rail.

[0039] like Figure 5 、 Figure 7 and Figure 8 As shown, in one embodiment, the rotating bracket 200 includes a horizontal rotating column 210, a transition column 220 and two vertical rotating columns 230. The horizontal rotating column 210 is arranged on the transition column 220, and the two vertical rotating columns 230 are respectively connected to both sides of the transition column 220. The horizontal rotating column 210 is rotatably connected to the power connection module 100.

[0040] like Figure 1 、 Figure 6 、 Figure 7 and Figure 8 As shown in one embodiment, the lamp body 300 includes a shell 310, two fixing members 320 and screws 330. The shell 310 is provided with a clearance groove 311, and the transition column 220 is located in the clearance groove 311. Two screw bosses 313 and two rotating protrusions 314 are provided in the shell 310. Each fixing member 320 is screwed to the corresponding screw boss 313 by a screw 330, so that the fixing member 320 and the screw boss 313 are firmly connected. In this embodiment, as shown in FIG. Figure 9 As shown, the fixing member 320 is provided with a through hole 323, and the screw boss 313 is provided with a screw hole 3131. The screwing portions of the screw 330 are respectively located in the through hole 323 and the screw hole 3131, and the top of the screw 330 abuts against the fixing member 320, thereby firmly connecting the fixing member 320 to the screw boss 313 and preventing the fixing member 320 from becoming loose from the screw boss 313. Furthermore, there are multiple screws 330, so as to securely connect the screw boss 313 and the fixing member 320.

[0041] like Figure 3 、 Figure 4 and Figure 8As shown, in one embodiment, each rotating protrusion 314 is provided with a first arc groove 3141, and the fixing member 320 is further provided with a second arc groove 321. The first arc groove 3141 and the second arc groove 321 constitute an accommodating channel 340, and the inner wall of the avoidance groove 311 is provided with two rotation avoidance holes 312. Each vertical rotating column 230 is passed through the corresponding rotation avoidance hole 312 and is interference-abutted against the inner wall of the accommodating channel 340, so that the rotating protrusion 314 and the fixing member 320 jointly clamp the vertical rotating column 230 and the vertical rotating column 230 is damped in the accommodating channel 340 to further rotate the lamp body 300 with the horizontal rotating column 210 as the horizontal rotation center, and the lamp body 300 rotates with the vertical rotation center formed by the vertical rotating column 230 and the transition column 220, and when there is no external force, the lamp body 300 can stably illuminate at any angle under vertical rotation. Specifically, the maximum angle of horizontal rotation is 350°, and the maximum angle of vertical rotation is 90°.

[0042] In this embodiment, the lamp body 300 can rotate with the horizontal rotation column 210 as the horizontal rotation center, and can also rotate with the vertical rotation center formed by the vertical rotation column 230 and the transition column 220, so that the grille light can be adjusted horizontally and vertically. At the same time, the fixing member 320 is screwed to the screw boss 313 by the screw 330. At this time, the vertical rotation column 230 is interference-abutted against the inner wall of the accommodating channel 340, and the fixing member 320 plays a role of pressing down and tightening through the screw 330, which can better fix the vertical rotation column 230, so that the lamp body 300 can provide stable lighting when it is rotated vertically to any angle.

[0043] It can be understood that when the vertical rotating column 230 is in interference fit with the inner wall of the accommodating channel 340, the lamp body 300 is rotated vertically to a certain angle by manpower. Since there is friction between the vertical rotating column 230 and the inner wall of the accommodating channel 340, the friction is balanced with the gravity of the lamp body 300, so that the grille light can illuminate stably at a specified angle without the lighting direction of the lamp body 300 gradually becoming facing the horizontal plane.

[0044] like Figure 3 and Figure 4 As shown, in one embodiment, the fixing member 320 is provided with a limiting post 322, and the rotating protrusion 314 defines a limiting hole 3142, and the limiting post 322 is located in the limiting hole 3142. It is understood that when the fixing member 320 is screwed to the rotating protrusion 314 via the screw 330, the limiting post 322 is located in the limiting hole 3142 to assist in fixing and further prevent the fixing member 320 and the rotating protrusion 314 from becoming loose.

[0045] like Figure 1 、 Figure 5 、 Figure 7 and Figure 8As shown, in one embodiment, a rotating boss 110 is provided at the bottom of the power connection module 100. The rotating boss 110 defines a rotation channel 111, and a horizontal rotating boss 210 is located within the rotation channel 111. This allows the lamp body 300 to be horizontally connected to the power connection module 100 via the rotating bracket 200, thereby enabling the lamp body 300 and the rotating bracket 200 to rotate horizontally in conjunction with the power connection module 100. Furthermore, the rotating boss 110 is provided with a retaining ring 112, which is located on the inner wall of the rotation channel 111. A contact ring 211 is provided at the top of the horizontal rotating boss 210, with which the rotating boss 112 abuts. It is understood that when the rotating boss 112 abuts the contact ring 211, the contact ring 211 lies above the rotating boss 112, preventing the rotating bracket 200 and the lamp body 300 from suddenly falling, thereby damaging the overall structure or injuring the user.

[0046] like Figure 8 As shown, in one embodiment, a first abutting block 2111 is protruded from the outer side of the abutting protrusion 211, and the rotating protrusion 110 is also provided with a second abutting block 113, and the second abutting block 113 is provided on the limiting protrusion 112. The first abutting block 2111 is used to abut against the second abutting block 113 when the rotating bracket 200 and the lamp body 300 are simultaneously rotated horizontally to a certain angle.

[0047] It can be understood that when the lamp body 300 rotates horizontally with the horizontal rotation column 210 as the center, the first abutment block 2111 rotates with the horizontal rotation column 210. When the lamp body 300 continues to rotate in the clockwise direction, the first abutment block 2111 abuts the first end surface of the second abutment block 113, preventing further clockwise rotation. When the lamp body 300 continues to rotate in the counterclockwise direction, the first abutment block 2111 abuts the second end surface of the second abutment block 113, preventing further counterclockwise rotation. When the first abutment block 2111 and the second abutment block 113 are provided, the abutment between the first abutment block 2111 and the second abutment block 113 prevents the lamp body 300 from rotating at any angle, thus preventing the cables within the lamp body 300 from becoming tangled.

[0048] Furthermore, if Figure 7 As shown, the housing 310 further defines a receiving groove 315 for accommodating the lighting assembly 21 .

[0049] like Figure 10As shown, the present disclosure also provides a rotating grille light 20, comprising a lighting assembly 21 and a push-down, fastened grille structure 10 according to any of the above-described embodiments. The lighting assembly 21 is mounted to a housing 310, and the power connection terminal of the power module 100 is electrically connected to the lighting assembly 21 via the rotating bracket 200 and the lamp body 300. Furthermore, the lighting assembly 21 is positioned within a receiving slot 315 of the lamp body 300, and the light-emitting portion of the lighting assembly 21 is positioned away from the bottom of the receiving slot 315 so that the light-emitting portion emits light to the outside through the opening of the receiving slot 315. It will be understood that when the rotating grille light 20 utilizes the push-down, fastened grille structure 10, the lamp body 300 can be manually rotated horizontally or vertically to adjust the illumination angle. With the fixing member 320 pressing down on the vertical rotating column 230, the illumination angle adjusted by vertical rotation can be maintained stable, allowing the grille light to provide stable illumination at a specified angle.

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

[0051] In the above-mentioned downward-pressing and fastening grille structure 10, the lamp body 300 can rotate with the horizontal rotation column 210 as the horizontal rotation center, and can also rotate with the vertical rotation center formed by the vertical rotation column 230 and the transition column 220, so that the grille lamp can be adjusted horizontally and vertically. At the same time, the fixing member 320 is screwed to the screw boss 313 by the screw 330. At this time, the vertical rotation column 230 is interference-abutted against the inner wall of the accommodating channel 340, wherein the fixing member 320 plays a downward-pressing and fastening role through the screw 330, which can better fix the vertical rotation column 230, so that the lamp body 300 can provide stable lighting when it is rotated vertically to any angle.

[0052] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
