Description

Technical Field

[0001] This invention relates to lighting fixtures, and more particularly to a mounting bracket for a lighting fixture. Background Technology

[0002] Lamps and lighting products are generally used to illuminate objects.

[0003] Moisture-proof lamps or ceiling lamps are a type of lighting fixture. When installed, the back of the lamp is completely attached to the ceiling. They are commonly used in homes, offices, entertainment venues, and other places.

[0004] The installation of moisture-proof lights or ceiling lights typically requires separating the lampshade from the base, securing the base to the ceiling with screws, and then reinstalling the lampshade. This process involves lifting the entire base close to the ceiling for securing, which is quite heavy and could easily damage the base if dropped. Furthermore, to ensure connection strength, most light fixtures require multiple screws for securing, making the prolonged upward tilting operation very strenuous. The lampshade also needs to be installed suspended, further complicating the installation process. Therefore, existing moisture-proof lights and ceiling lights present installation difficulties. Summary of the Invention

[0005] The purpose of this invention is to provide a mounting bracket for lamps, which has the advantage of convenient installation.

[0006] To achieve the above objectives, the solution of the present invention is:

[0007] A mounting bracket for a lamp includes a fixed bracket, a locking bracket, and a locking device. The fixed bracket is fixed to a ceiling or wall. The locking bracket is attached to the base of the lamp. The locking bracket includes a mounting groove with a side opening, and the fixed bracket slides within the mounting groove from the side opening. A locking device is provided at the side opening of the mounting groove to prevent the fixed bracket from sliding out of the mounting groove. The locking device includes a limiting mechanism. The limiting mechanism includes a locking block that can vertically reciprocate by extending or retracting into the locking bracket. When the locking block extends out of the surface of the locking bracket, its side abuts against the side of the fixed bracket.

[0008] Furthermore, the locking device also includes a pushing mechanism; the pushing mechanism includes a sliding block that can slide horizontally back and forth, the inner end of the sliding block is linked to the locking block, and the outer end of the sliding block is exposed on the outer side of the base of the lamp; controlling the horizontal movement of the sliding block can link the vertical movement and retraction of the locking block.

[0009] Furthermore, the limiting mechanism also includes a receiving cavity and a spring; the receiving cavity is disposed adjacent to the opening side and is vertically formed within the locking bracket; the locking block is vertically installed within the receiving cavity, with the inner end of the locking block located within the receiving cavity and the outer end of the locking block having a locking part; one end of the spring abuts against the bottom wall of the receiving cavity and the other end abuts against the inner end of the locking block; the side of the locking part movably abuts against the side of the fixed bracket.

[0010] Furthermore, a vertical guide groove is formed on the side wall of the accommodating cavity, and a guide rib is protruding from the side of the locking block facing the guide groove, and the guide rib can slide up and down along the guide groove.

[0011] Furthermore, the limiting mechanism also includes a receiving cavity and a spring; the receiving cavity is disposed adjacent to the opening side and vertically formed within the locking bracket; the locking block is vertically installed within the receiving cavity, with its inner end located within the receiving cavity and its outer end provided with a locking portion; one end of the spring abuts against the bottom wall of the receiving cavity, and the other end abuts against the inner end of the locking block; the side of the locking portion movably abuts against the side of the fixed bracket; the pushing mechanism also includes a sliding cavity and a cover plate; the sliding cavity is horizontally disposed on the locking bracket and communicates with the receiving cavity; the sliding cavity is covered by a cover plate, and the cover plate is provided with a clearance opening corresponding to the locking block; the sliding block can slide horizontally within the sliding cavity and is limited by the cover plate;

[0012] Furthermore, the outer end of the locking block is provided with a first inclined surface at a certain angle, and the first inclined surface is located on both sides of the locking part; the inner end of the sliding block is provided with a relief groove, which allows the locking part to pass through vertically and make horizontal displacement. One end of the relief groove is provided with a second inclined surface corresponding to the first inclined surface. The second inclined surface fits into the first inclined surface. When force is applied to make the sliding block move horizontally inward, the second inclined surface slides inward and the first inclined surface rises upward, causing the locking part to retract from the relief opening into the locking bracket.

[0013] Furthermore, the clearance groove is vertically continuous and closed on all sides, so that the sliding block is horizontally limited to the locking block.

[0014] Furthermore, the sliding block includes a first sliding part, a second sliding part, and a pushing part. An inclined connecting part connects the first sliding part and the second sliding part, and the second sliding part is connected to the pushing part. The first sliding part is the inner end of the sliding block and is embedded in the sliding cavity. The pushing part is the outer end of the sliding block and is exposed on the outer side of the locking bracket. The bent connecting part limits the first sliding part to the limiting surface of the locking bracket.

[0015] Furthermore, the cover plate includes a first cover plate that aligns and covers the outer side of the first sliding part, a connecting cover that aligns and covers the outer side of the connecting part, and a second cover plate that aligns and covers the outer side of the second sliding part.

[0016] The second cover plate has connecting walls extending on both sides. The connecting walls are provided with oppositely arranged locking blocks. The locking bracket has two baffles protruding from the two connecting walls. Both baffles are provided with slots for the aligning locking blocks. When the second cover plate is closed on the outside of the second sliding part, the locking blocks of the connecting walls are engaged with the slots of the baffles.

[0017] Furthermore, the mounting groove is composed of two fixing grooves located on the left and right sides of the locking bracket, respectively. The two fixing grooves are arranged opposite each other, and each fixing groove has an opening on the same side and a baffle on the other side. The fixing bracket has connecting lugs at both ends that can be confined within the two fixing grooves.

[0018] By adopting the above technical solution and utilizing the structure of the present invention, when installing the lamp, a relatively lightweight fixing bracket can be pre-fixed. Then, the mounting slot of the lamp's locking bracket can be quickly slid into the fixing bracket. The fixing bracket can then be limited by a locking device at the opening on the side of the mounting slot, thus achieving quick and convenient installation of the lamp and ensuring its stability after installation.

[0045] Furthermore, this application provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0046] like Figure 1 As shown, a mounting bracket 10 for a lamp according to the present invention includes a fixing bracket 1, a locking bracket 2 and a locking device 3.

[0047] like Figure 3 and Figure 4 As shown, the fixing bracket 1 is a sheet-like structure, including connecting ears 11 at both ends of the fixing bracket 1, and at least two connecting holes 12 that pass through the fixing bracket 1 vertically and are spaced apart. By passing screws or bolts through the connecting holes 12, the fixing bracket 1 can be pre-locked to the ceiling, wall, or other locations.

[0048] like Figure 2As shown, the locking bracket 2 is attached to the base 201 of the lamp 20. It can be integrated with the base 201 or be separate from it. In this embodiment, the locking bracket 2 and the base 201 of the lamp 20 are integrated.

[0049] like Figure 1 and Figure 2 As shown, the locking bracket 2 includes a mounting groove 21 with a side opening 211. The fixing bracket 1 slides from the side opening 211 and is limited to the mounting groove 21. In this embodiment, the mounting groove 21 is composed of two fixing grooves 212 located on the left and right sides of the locking bracket 2, respectively. The two fixing grooves 212 are arranged opposite to each other, and each fixing groove 2122 has an opening 2121 on the same side and a baffle 2122 on the other side. In this embodiment, the opening 2121 is provided on the rear side of the two fixing grooves 212, and the baffle 2122 is provided on the front side. The connecting ears 11 of the fixing bracket 1 can slide forward from the opening 2121 into the two fixing grooves 212 and abut against the baffle 2122, so that the fixing bracket 1 can be unidirectionally embedded in the two fixing grooves 212. In other words, when installing, the lamp 20 is installed on the fixing bracket 1 from front to back, and the lamp 20 can be fixed on the fixing bracket 1.

[0050] A locking device 3 is provided at the side opening 211 of the mounting groove 21 to limit the movement of the bracket 1 to slide backward out of the mounting groove 21, so as to lock and fix the installed lamp 20.

[0051] Therefore, when installing the lamp 20, after the lightweight fixing bracket 1 is fixed in advance with screws, the mounting groove 21 of the locking bracket 2 of the lamp 20 is quickly slidably engaged with the fixing bracket 1, and then the fixing bracket 1 is limited by the locking device 3, so that the lamp 20 can be installed quickly and conveniently.

[0052] The locking device 3 includes a limiting mechanism 31 and a pushing mechanism 32.

[0053] like Figure 3 and Figure 4 As shown, the limiting mechanism 31 is disposed within the locking bracket 2 and is located adjacent to the side opening 211; the limiting mechanism 31 includes a vertically movable locking block 311, which can vertically reciprocate by extending or retracting into the locking bracket 2. When the locking block 311 extends out of the surface of the locking bracket 2, its side abuts against the side of the fixed bracket 1 (e.g., Figure 1 As shown), the pushing mechanism 32 is horizontally arranged and includes a sliding block 321 that can slide horizontally back and forth. The inner end of the sliding block 321 is linked to the locking block 311, and the outer end of the sliding block 321 is exposed on the outer side of the locking bracket 2. The sliding block 321 can be controlled to move horizontally from the outer side of the locking bracket 2, that is, the outer side of the lamp 20, and the locking block 311 can be moved vertically and retracted, thereby releasing the locking block 311 from locking the fixed bracket 1.

[0054] The limiting mechanism 31 of the locking device 3 limits the fixed bracket 1 and the lamp 20 by extending the locking block 311, preventing the fixed bracket 1 from falling off the mounting slot 21 and ensuring the stability of the lamp 20 after installation. Furthermore, a pushing mechanism 32 is provided, with a sliding block 321 exposed on the side of the lamp 20. Pushing the sliding block 321 from the side of the lamp 20 causes the locking block 311 to retract, facilitating the removal of the lamp 20 and simplifying subsequent maintenance and replacement operations.

[0055] Specifically, such as Figure 3 and Figure 5 As shown, the limiting mechanism 31 also includes a receiving cavity 312 and a spring 313.

[0056] The receiving cavity 312 is located on the side of the fixed bracket 1 near the opening 2121 of the fixed groove 212 and is vertically formed in the locking bracket 2; the locking block 311 is vertically installed in the receiving cavity 312, the inner end of the locking block 311 is located in the receiving cavity 312, and the outer end of the locking block 311 is provided with a locking part 3111. One end of the spring 313 abuts against the bottom wall of the receiving cavity 312, and the other end abuts against the inner end of the locking block 311, so that the locking part 3111 of the locking block 311 is pushed outward by the spring 313 and extends outward into the receiving cavity 312, so that the side of the locking part 3111 can abut against the side of the fixed bracket 1, restricting the fixed bracket 1 from sliding out of the opening 2121 of the fixed groove 212.

[0057] A vertical guide groove 3121 is formed on the side wall of the accommodating cavity 312. A guide rib 3112 protrudes from the side of the locking block 311 facing the guide groove 3121. The guide rib 3112 can slide up and down along the guide groove 3121 to stably drive the locking block 311 to slide up and down.

[0058] Specifically, such as Figure 3 and Figure 6 , Figure 7 As shown, the pushing mechanism 32 also includes a sliding cavity 322 and a cover plate 323.

[0059] The sliding cavity 322 is horizontally disposed on the locking bracket 2 and communicates with the receiving cavity 312. The sliding cavity 322 is covered by a cover plate 323, and the cover plate 323 is provided with a clearance opening 3231 corresponding to the locking block 311.

[0060] The sliding block 321 is horizontally slidable within the sliding cavity 322 and is limited by the cover plate 323. The locking block 311 has a first inclined surface 3113 at a certain angle at its outer end. The first inclined surface 3113 is located on the side away from the guide rib 3112 and can be located on both sides of the locking part 3111. The outer end of the sliding block 321 is exposed on the side of the locking bracket 2, and the inner end is provided with a clearance groove 3211. The clearance groove 3211 allows the locking part 3111 to pass through vertically and to make horizontal displacement. One end of the clearance groove 3211 has a second inclined surface 3212 corresponding to the first inclined surface 3113. The second inclined surface 3212 fits against the first inclined surface 3113. When force is applied to make the sliding block 321 move horizontally inward, the second inclined surface 3212 slides inward and moves the first inclined surface 3113 downward, so that the locking block 311 can retract downward and compress the spring 313. The locking part 3111 retracts from the clearance opening 3231 into the locking bracket 2, releasing the locking part 3111 from limiting the fixed bracket 1. When the sliding block 321 is released, the locking block 311 will extend outward due to the rebound force of the spring 313, returning to the initial state. Meanwhile, in this embodiment, the clearance groove 3211 is open vertically and closed on all sides. When the locking block 311 extends vertically outward, the sliding block 321 also slides horizontally outward. The clearance groove 3211 limits the sliding range of the sliding block 321 by limiting the locking block 311 and preventing the sliding block 321 from disengaging from the sliding cavity 322.

[0061] like Figure 4 As shown, the sliding block 321 includes a first sliding portion 3213, a second sliding portion 3214, and a pushing portion 3215. An inclined connecting portion 3216 connects the first sliding portion 3213 and the second sliding portion 3214, and the second sliding portion 3214 is connected to the pushing portion 3215. The first sliding portion 3213 is the inner end of the sliding block 321 and is slidably embedded in the sliding cavity 322. The pushing portion 3215 is the outer end of the sliding block 321 exposed on the outer side of the locking bracket 2 (see reference). Figure 1 The bent connecting portion 3216 allows the first sliding portion 3213 to be confined on a limiting surface 22 of the locking bracket 2 (see reference). Figure 3 This also prevents the sliding block 321 from disengaging from the sliding cavity 322.

[0062] The cover plate 323 includes a first cover plate 3232 that aligns and covers the outside of the first sliding part 3213, a connecting cover 3233 that aligns and covers the outside of the connecting part 3216, and a second cover plate 3234 that aligns and covers the outside of the second sliding part 3214, so that the sliding block 321 can be slidably placed in the sliding cavity 322.

[0063] Furthermore, the second cover plate 3234 has connecting walls 3235 extending on both sides. The connecting walls 3235 are provided with oppositely arranged locking blocks 3236. The locking bracket 2 has two baffles 23 protruding from the two connecting walls 3235. Both baffles 23 are provided with slots 231 for aligning locking blocks 3236. When the second cover plate 3234 is closed on the outside of the second sliding part 3214, the locking blocks 3236 of the connecting walls 3235 can be fitted into the slots 231 of the baffles 23. At this time, the sliding block 321 is slidably limited within the sliding cavity 322, and the cover plate 323 and the locking bracket 2 are installed, which can improve the installation efficiency of the product. At the same time, the cover plate 323 can be firmly fixed to the locking bracket 2 by passing the screw 4 through the connecting hole 3237 provided on the first cover plate 3232.

[0064] The above description is merely a preferred embodiment of the present invention, and the scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, equivalent changes and modifications without departing from the principle of the present invention should still fall within the scope of protection of the present invention.
