Description

Technical Field

[0002] At present, for some panel lights used in indoor and outdoor commercial activities, party celebrations, large-scale performances, film and television production and other use scenarios, they often encounter problems such as limited location of the actual shooting site, insufficient light or excessive light. This requires adjusting the placement, quantity and light output angle of the panel lights to fill in or block light, so as to obtain better lighting effects. Among them, in order to obtain better light output effects, it is often necessary to splice multiple relatively small panel lights to form a relatively large panel light with better light output effects, so as to form a light wall curtain or ceiling curtain. When splicing existing panel lights, multiple screws and corresponding nuts and gaskets and other accessories are often required to achieve a firm assembly. The assembly is not convenient and the assembly efficiency is relatively low.

[0028] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.

[0029] See also Figures 1 to 12 The utility model discloses a U-shaped connection assembly 100, which is suitable for the splicing of panel lamps 200, and is intended to connect a single relatively small panel lamp 200 into a relatively large panel lamp to form a light wall lamp curtain or a ceiling lamp curtain, so as to obtain the desired light-emitting effect, and is better applied to various indoor and outdoor commercial activities, party celebrations, large-scale performances and film and television productions that have certain requirements for light-emitting effects. Among them, the lamp body 201 of the panel lamp 200 is square or rectangular as a whole, and includes a frame 2011 of a corresponding shape and a rear cover plate 2012 that closes the rear side end of the lamp body 201. The frame 2011 and the rear cover plate 2012 can be made of aluminum alloy material and have a certain heat dissipation effect. Of course, the panel lamp 200 also includes a light source module, a control module 202, a drive module and a radiator 203, etc., which are arranged on the lamp body 201. The color temperature and brightness of the light source are adjustable as needed. The specific structure of the panel lamp 200 is not the focus of protection of this application, and will not be repeated here.

[0030] See below Figures 1 to 8, the specific structure of the first embodiment of the U-shaped connection assembly 100 of the utility model is described:

[0031] See first Figure 1 and Figure 2 In general, in this embodiment, the U-shaped connection assembly 100 provided by the utility model includes a through hole 10 arranged on the peripheral side of the lamp body 201 of the panel lamp 200 and a multi-section U-shaped plug-in rod 20 detachably connected to the through hole 10. Among them, the multi-section U-shaped plug-in rod 20 includes a U-shaped rod 21 and two first straight rods 22 pivotally connected to the two side arms 211 of the U-shaped rod 21 in a one-to-one correspondence. When the multi-section U-shaped plug-in rod 100 is inserted into the through hole 10 of one of the two adjacent panel lamps 200 and passes through the correspondingly arranged through hole 10 of the other to achieve the splicing of the two, the closed end of the U-shaped rod 21 is clamped at the entrance of the through hole 10 at the insertion end, at least one side arm 211 of the U-shaped rod 21 is clamped in the through hole 10 at the insertion end, and the first straight rod 22 pivotally connected thereto is clamped in the through hole 10 at the exit end, so that the U-shaped rod 21 and the first straight rod 22 connected thereto are connected to the through hole 10 at the insertion end. The multi-stage snap-fit ​​structure of the straight rod 22 in the corresponding two penetration holes 10 realizes the firm assembly of adjacent panel lights 200; or, at least one side arm 211 of the U-shaped rod 21 is snap-fitted into the two penetration holes 10 at the insertion end and the exit end at the same time, and the first straight rod 22 pivotally connected thereto passes through the penetration hole 10 at the exit end and rotates relative to the penetration hole 10 to snap-fit ​​into the exit of the penetration hole 10, thereby forming an anti-slip portion, which effectively enhances the stability of the connection between adjacent panel lights 200. In the present application, the U-shaped connection assembly 100 is not only applicable to the one-way splicing of 2, 4, 6 and 8 panel lights 200, but also applicable to the splicing of panel lights 200 in different directions, such as Figure 2 As shown, the panel lights 200 arranged along the front-to-back direction and the left-to-right direction can be spliced ​​at the same time, and can be extended in multiple directions on this basis as needed, so that the use is more flexible and the application range is wider.

[0032] See also Figures 1 to 3Specifically, in this embodiment, the through hole 10 is directly arranged on the frame 2011 of the lamp body 201. At this time, the height of the top surface of the frame 2011 is higher than the height of the end surface of the rear cover 2012 of the lamp body 201. At least two through holes 10 are respectively arranged at the head and tail ends of each side of the square frame 202, and the through holes 10 on the two opposite sides are arranged symmetrically, so that the front and rear adjacent and left and right adjacent panel lights 200 are conveniently connected through the correspondingly arranged through holes 10. More specifically, two through holes 10 are respectively arranged at the head and tail ends of each side of the frame 2011 for corresponding clamping of two multi-section U-shaped plug-in rods 20. Furthermore, four through holes 10 are respectively provided at the head and tail ends of each side of the frame 2011, so that the head and tail ends of each side are respectively connected by two multi-section U-shaped plug-in rods 20, effectively improving the stability of the splicing between the panel lights 200.

[0033] Combination Figure 3 and Figure 4 In order to achieve effective clamping between the multi-section U-shaped plug-in rod 20 and the through hole 10, the multi-section U-shaped plug-in rod 20 can be clamped in the corresponding through hole 10 with an interference fit, and the interference fit is slight, so as to facilitate press-fitting and disassembly. Of course, the multi-section U-shaped plug-in rod 20 can also be inserted in the through hole 10 with a clearance fit, and the clamping assembly 30 can be used to achieve the clamping of the two.

[0034] Specifically, the rod diameter of the multi-section U-shaped plug-in rod 20 is smaller than the hole diameter of the penetration hole 10, and the clamping assembly 30 includes a groove 31 arranged on the outer wall of the U-shaped rod 21 or / and the first straight rod 22 and having a certain curvature, and the groove 31 on the U-shaped rod 21 is specifically arranged on the side arm 211, and a clamping portion 32 is arranged in a radially telescopic manner in the penetration hole 10, and the clamping portion 32 is used to extend into the groove 31 or withdraw from the groove 31 to clamp or release the U-shaped rod 21 or / and the first straight rod 22 inserted in the penetration hole 10. More specifically, a receiving groove 11 arranged in the radial direction of the penetration hole 10 is provided on the inner hole wall of the penetration hole 10, and the clamping portion 32 is telescopically arranged in the receiving groove 11 by a spring 33, and the spring 33 constantly drives the clamping portion 32 to move in a direction close to the penetration hole 10.

[0035] When in use, as the multi-section U-shaped plug-in rod 20 is inserted into the through hole 10, the clamping portion 32 is pushed to move away from the through hole 10 until it retracts into the accommodating groove 11 to make way, at which time the spring 33 is compressed, and when the multi-section U-shaped plug-in rod 20 continues to be inserted until it is in place, the groove 31 on the outer wall of the U-shaped rod 21 or / and the first straight rod 22 is just opposite to the clamping portion 32, and the clamping portion 32 then moves toward the direction close to the through hole 10 under the action of the restoring force of the spring 33 to extend into the groove 31, thereby realizing the clamping and positioning of the multi-section U-shaped plug-in rod 20 through the concave-convex cooperation of the two. Among them, the number of the clamping components 30 in the through hole 10 can be two, and they are arranged symmetrically, so as to achieve more stable clamping and positioning.

[0036] See also Figure 3 The U-shaped connection assembly 100 of the utility model also includes a positioning magnet 40, which is arranged on the frame 2011 of the lamp body 201, and is specifically pasted on the frame 2011, and is used to fix the first straight rod 22 after rotation, so that it can be better maintained in the anti-slip position, and further improve the stability of the assembly. Among them, the positioning magnet 40 and the penetration hole 10 are arranged in a one-to-one correspondence, or a positioning magnet 40 is provided at the edge of each penetration hole 10 along a perpendicular direction to correspond to the positioning of the first straight rod 22 in different rotation directions. It should be noted that, regardless of whether the side arm 211 and the penetration hole 10 are interference fit or intermittent fit, the first straight rod 22 used for anti-slipping can be positioned by the positioning magnet 40, thereby improving the anti-slipping effect. Of course, the positioning magnet 40 can also replace the clamping assembly 30 used for clamping, thereby simplifying the structure.

[0037] See also Figure 5 The multi-section U-shaped plug-in rod 20 has a first structure: the two first straight rods 22 are symmetrically pivoted on the two side arms 211 of the U-shaped rod 21, so that they can rotate in the same direction relative to the U-shaped rod 31, specifically 90°. This structure is relatively simple and easy to process. Specifically, one of the pivot ends of the U-shaped rod 21 and the first straight rod 22 is provided with a first receiving groove 24, and the other is convexly provided with a first pivot block 25. The first pivot block 25 is pivoted in the first receiving groove 24 through a pivot shaft 26, and the rotation direction of the first pivot block 25 is determined by the opening direction of the first receiving groove 24. In addition, the two side arms 211 of the U-shaped rod 21 and the two first straight rods 22 can be set with equal diameters, and grooves 31 for clamping can be provided on the outer side walls.

[0038] More specifically, the first receiving groove 24 is formed by the relative center of the top wall of the first straight rod 22 being recessed toward the bottom wall thereof, and is arranged to penetrate the front and rear side walls of the first straight rod 22, and the first pivot block 25 is pivoted in the first receiving groove 24 through the pivot shaft 26 arranged along the left and right directions, so that it can rotate relatively in the front and rear directions. Of course, the first receiving groove 24 can also be arranged to penetrate the left and right side walls of the first straight rod 22, and the first pivot block 25 is pivoted in the first receiving groove 24 through the pivot shaft 26 arranged along the front and rear directions, so that it can rotate relatively in the left and right directions, as long as the opening directions of the first receiving grooves 24 on both sides are consistent. When in use, the multi-section U-shaped plug-in rod 20 is simultaneously inserted from two through holes 10 arranged side by side on one panel light 200 into two corresponding through holes 10 arranged in an adjacent panel light 200.

[0039] See also Figure 6 The multi-section U-shaped plug-in rod 20 also has a second structure, which is mainly different from the first structure in that the rotation directions of the two first straight rods 22 in the multi-section U-shaped plug-in rod 20 are not the same, that is, the pivoting structures between the two first straight rods 22 and the two side arms 211 are different. Specifically, the pivoting structure between the first straight rod 22 and the side arm 211 on one side is still consistent with the first structure, while the first receiving groove 24 on the other side can be formed by the relative center of the bottom wall of the side arm 211 on this side being recessed toward the direction of its top wall, and is arranged to penetrate the left and right side walls of the side arm 211. The first pivot block 25 is convexly arranged on the top side end of the first straight rod 22, and is pivoted in the first receiving groove 24 through the pivot shaft 26 arranged in the front-to-back direction, so that it can rotate relatively in the left and right directions. Then the two first straight rods 22 of the multi-section U-shaped plug-in rod 20 of this structure can rotate in different directions relative to the U-shaped rod 21, thereby improving the flexibility of use. The other similarities are not described again.

[0040] See also Figure 7 The multi-section U-shaped plug-in rod 20 also has a third structure, which is different from the first structure mainly in that it also includes two second straight rods 23 pivotally connected to the two first straight rods 22 in a one-to-one correspondence. Correspondingly, a second receiving groove 27 is provided on one of the pivoting ends of the first straight rod 22 and the second straight rod 23, and a second pivot block 28 is convexly provided on the other. The second pivot block 28 is also pivotally connected to the second receiving groove 27 through the pivot shaft 26. The rotation direction of the second pivot block 28 is determined by the opening direction of the second receiving groove 27. When the thickness of the frame 2011 is relatively thick, and the first straight rod 22 is engaged in the through hole 10 at the through end, the second straight rod 23 pivotally connected thereto can be passed through the through hole 10 at the through end and then rotated relative to the first straight rod 22 at a certain angle to be engaged at the outlet of the through hole 10 at the through end, thereby forming an anti-slip portion, which effectively enhances the stability of the connection between adjacent panel lights 200.

[0041] The rotation direction between the two second straight rods 23 can be the same, and its specific structure is roughly the same as the pivot structure between the two first straight rods 22 and the U-shaped rod 21 in the first structure. Specifically, the two second straight rods 23 are symmetrically pivoted on the two first straight rods 22, so that they can rotate in the same direction relative to the two first straight rods 22, and the rotation direction of the two is also the same as the rotation direction of the first straight rod 22. More specifically, the first receiving groove 24 and the second receiving groove 27 are symmetrically arranged at the top and bottom ends of the first straight rod 22, and the side arm 211 of the U-shaped rod 21 and the pivot end of the second straight rod 23 are correspondingly provided with a first pivot block 25 and a second pivot block 28 that match the first receiving groove 24 and the second receiving groove 27.

[0042] It should be noted that when the side arm 211 is engaged in the through hole 10 and the first straight rod 22 connected thereto is engaged at the outlet of the through hole 10 at the through end, the second straight rod 23 pivotally connected thereto can also rotate at a certain angle relative to the first straight rod 22 and be engaged with the lamp body 201 from another direction, further forming an anti-slip portion, and further strengthening the stability of the connection between adjacent panel lamps 200. The multi-section U-shaped plug-in rod 100 also includes anti-slip holes 50 arranged one by one on the lamp body 201 beside the through hole 10, and the second straight rod 23 rotates relative to the first straight rod 22 toward the direction of the anti-slip holes 50, so as to be engaged with the two anti-slip holes 50 correspondingly arranged on the adjacent panel lamps 200. At this time, the multi-section U-shaped plug-in rod 100 is roughly in the shape of a "bow", and the assembly effect is better.

[0043] Among them, when four through holes 10 arranged side by side are respectively provided at the head and tail ends of the frame 2011, the multi-section U-shaped plug-in rod 100 can be inserted from the two middle through holes 10, and after passing through the two middle through holes 10 in the adjacent panel lamp 200, the two first straight rods 22 are respectively rotated in the direction parallel to the frame 2011, and the two second straight rods 23 are then rotated in the direction perpendicular to the frame 2011, so as to respectively penetrate from the two through holes 10 at the two side edges, and be inserted into the through holes 10 corresponding to the panel lamp 200 at the insertion end, so as to achieve anti-slip connection. At this time, the two through holes 10 arranged at the edge are the anti-slip holes 50 that play an anti-slip role.

[0044] See also Figure 8 The multi-section U-shaped plug-in rod 20 also has a fourth structure, which is different from the third structure in that the rotation direction between the two second straight rods 23 and the rotation direction between the two and the two first straight rods 22 can be different. The specific pivot structure of the second structure that rotates in different directions is roughly the same, and will not be repeated here.

[0045] See below Figures 9 to 12 , the specific structure of the second embodiment of the U-shaped connection assembly 100 of the utility model is described:

[0046] The main difference between the U-shaped connection assembly 100 of the first embodiment is that, in this embodiment, the through hole 10 is not directly arranged on the lamp body 201, but is arranged on the lamp body 201 through a positioning block 60. Specifically, a positioning block 60 is provided at each of the four top corners of the rear cover 2012 of the lamp body 201, and the positioning block 60 is provided with through holes 10 arranged along the front-back direction and along the left-right direction, respectively, and the through holes 10 in the two directions are arranged staggered along the up-down direction. This structure is more suitable for the splicing of panel lamps 200 whose frame 2011 and the rear cover 2012 are roughly flush, and the additional positioning block 60 can conveniently and quickly realize the matching of the multi-section U-shaped plug-in rod 20 and the through hole 10. In addition, the various structures of the multi-section U-shaped plug-in rod 20 in the first embodiment are applicable to this embodiment, and the matching relationship between the multi-section U-shaped plug-in rod 20 and the through hole 10 is also roughly the same, except that the specific length and rod diameter are adaptively adjusted according to the length and width of the positioning block 60. In addition, in this embodiment, the positioning magnet 40 can be directly arranged on the positioning block 60, so as to facilitate the positioning of the second straight rod 23 for preventing the second straight rod 23 from falling off, and effectively improve the anti-falling effect.

[0047] See also Fig.10 and Fig.11 When the panel lights 200 are only spliced ​​in one direction, such as only spliced ​​in the front-to-back direction or the left-to-right direction, the Fig.11 As shown, the U-shaped rod 21 can simply and conveniently realize the splicing of adjacent panel lights 200 only through the clamping of one side arm 211 and a first straight rod 22 connected thereto and the corresponding two through holes 10. Moreover, since only one side is clamped, it is also convenient to operate on the other side for easy press-fitting and disassembly.

[0048] See also Fig.10 and Fig.12 When the panel lights 200 are sequentially spliced ​​in different directions, such as when they are spliced ​​in the front-to-back direction and the left-to-right direction at the same time, the Fig.12 As shown, at the edge, the through holes 10 on the two corresponding positioning blocks 60 can still be unilaterally clamped by a side arm 211 and a first straight rod 22 connected thereto, while on the four positioning blocks 60 at the center position, two multi-section U-shaped plug-in rods 20 are respectively clamped with the through holes 10 on the four positioning blocks 60 in two directions to achieve splicing. Specifically, the multi-section U-shaped plug-in rod 20 is correspondingly inserted into the through holes 10 of the two side-by-side positioning blocks 60, and passes through the through holes 10 of the two side-by-side positioning blocks 60 on the adjacent panel lights 200, and the two second straight rods 23 are correspondingly clamped on the two positioning blocks 60 at the passing end, and can be anti-dropped and positioned by the positioning magnets 40 correspondingly arranged on the two positioning blocks 60 on this side.

[0049] Of course, in other embodiments, the number of through holes 10 in each direction on the positioning block 60 can also be 2, and the two through holes 10 can be arranged side by side or in parallel in this direction, and staggered with the through holes 10 in the other direction. At this time, each positioning block 60 can adapt to the simultaneous clamping of the two side arms 211 of a U-shaped plug-in rod 20 and the two first straight rods 22.

[0050] Compared with the prior art, in the U-shaped connection assembly 100 disclosed in the present invention, since the two first straight rods 22 of the multi-section U-shaped plug-in rod 20 are pivotally connected to the two side arms 211 of the U-shaped rod 21 in a one-to-one correspondence, and the through holes 10 engaged therewith are arranged on the peripheral side of the lamp body of the panel lamp 200, when in use, it is only necessary to insert the multi-section U-shaped plug-in rod 20 into the through hole 10 of one of the two adjacent panel lamps 200 and pass it out from the through hole 10 of the other correspondingly arranged panel lamp, so that the two can be conveniently and quickly spliced, wherein, by engaging the closed end of the U-shaped rod 21 at the entrance of the through hole 10 of the insertion end, the entire multi-section U-shaped plug-in rod 20 is effectively prevented from being inserted from the entrance The U-shaped rod 21 is disengaged from the insertion end, and at least one side arm 211 of the U-shaped rod 21 is snapped into the through hole 10 at the insertion end, and the first straight rod 22 pivotally connected thereto is snapped into the through hole 10 at the exit end, so that the two adjacent panel lamps 200 are firmly connected by the snap connection of multiple rod sections; of course, at least one side arm 211 of the U-shaped rod 21 can also be snapped into the two through holes 10 at the insertion end and the exit end at the same time to realize the connection between the two adjacent panel lamps 200, and the first straight rod 22 pivotally connected thereto is snapped into the exit of the through hole 10 by rotating relative to the through hole 10 at the exit end, thereby playing an anti-detachment role and further enhancing the stability of the connection between the two panel lamps 200. The U-shaped connection assembly 100 of the utility model has a simple overall structure. Different from the traditional screw-connected assembly, it does not require the cooperation of tools such as a screwdriver. It only needs to be manually pressed or the protruding first straight rod 22 is rotated and bent after being pressed to achieve splicing and anti-slip operations. The operation is convenient and the splicing efficiency is high. According to needs, splicing can be achieved only through the cooperation of one side arm 211 and the first straight rod 22 pivoted thereto and the corresponding through-hole 10. It can also be achieved by the cooperation of two side arms 211 and the two first straight rods 22 pivoted thereto and the corresponding through-hole 10 at the same time, which effectively improves adaptability and is more economical and practical.

[0051] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
