[0046] refer to Figure 1-Figure 8 Traditional stadium lighting lamps usually adopt an integrated structure, which is locked on the pole with a bolt group and a clamp. When the shell and related components of the lighting lamp are exposed to wind and sun and become brittle, cracked, or damaged and deformed due to collision, it is not convenient to disassemble and replace them separately. In this regard, the present application designs an adaptive instantaneous installation stadium lighting lamp;
[0047] In order to overcome the above-mentioned defects, the present application designs an adaptive instantaneous installation stadium lighting lamp, wherein the lighting part 2 mainly includes a mounting plate 21, a locking ring 22, a combination component 23 and a lighting lamp body 24, wherein the main body of the combination component 23 adopts a detachable structure:
[0048] Installation method and angle adjustment of the mounting plate 21 and the rotating member 232:
[0049] Initially, the mounting plate 21 and the locking ring 22 are sleeved on the outer circumference surface of the pole body 1, and locked and installed by the thread group, so that the mounting plate 21, the locking ring 22 and the pole body 1 are combined into a whole. Then, the tooth block 2329 on the rotating member 232 is manually pulled outward, driving the square rod 2328 to slide outward along the inside of the hollow tube 2327 with damping until the tooth block 2329 is separated from the tooth plate 2325. At this time, the rotating block 2323 can rotate freely around the outer circumference surface of the shaft rod 2322, thereby realizing the adjustment of the inclination angle of the sleeve 231, and at the same time, it is convenient for the subsequent instantaneous installation and removal of the instantaneous coupling member 233 and the lighting lamp body 24. After the adjustment is completed, only the tooth block 2329 and the square rod 2328 need to be reset (there are two groups of square rods 2328, and the adjacent ends of the two are magnetically connected. When the adjacent ends are close to each other, they are tightly attracted together by magnetic force to avoid lateral movement of the square rod 2328 during subsequent use), and the tooth block 2329 and the tooth plate 2325 are meshed and combined into a whole again to limit it.
[0050] Combined with the instantaneous installation method and the instantaneous removal method of component 23:
[0051] As can be seen from the above, the sleeve 231 on the coupling assembly 23 is in a downward tilted state (see Figure 4As shown by the downward arrow in the figure, the sleeve 231 is free to tilt downward under the action of gravity at this time, which is used for good directional control of the light. The lighting lamp body 24 is fixed to the end of the coupling tube 2331 of the instantaneous coupling member 233. It is only necessary to combine the instantaneous coupling member 233, the sleeve 231 and the magnetic member 234 into a whole to complete the installation of the lighting lamp body 24. When the sleeve 231 is tilted, the counterweight plate 2341 on the magnetic member 234 slides downward along the inner wall of the slide groove 2311 with the help of the slider 2342 under the action of its own gravity until the outer surface of the counterweight plate 2341 fits with the end surface of the limit ring 2312. Next, insert the coupling tube 2331 on the instant-acting coupling part 233 into the sleeve 231, and the end face of the coupling tube 2331 will also be attached to the end face of the limiting ring 2312. At the same time, the magnetic block 2343 quickly acts on the magnetic plate 2333 on the instant-acting coupling part 233 (the magnetic plate 2333 is initially hidden in the coupling tube 2331). The magnetic block 2343 and the magnetic plate 2333 are quickly attracted, and the magnetic plate 2333 drives the inclined plane block 2332 to slide outward along the outer surface of the smooth rod circumference. The inclined plane block 2332 pushes the triangular block 2334 and the coupling rod 2335 to slide outward (the return spring 2336 is elastically deformed under pressure), and the coupling rod 2335 is quickly inserted into the ear block 2313, completing the instant-acting installation of the instant-acting coupling part 233, the sleeve 231 and the magnetic part 234.
[0052] In summary, the application adopts the combination component 23 has the following advantages:
[0053] Advantage 1: The rotating part 232 can freely adjust the illumination range of the sleeve 231, the instantaneous coupling part 233, and the lighting lamp body 24. The operation is simple and convenient. In addition, there are two groups of square rods 2328. The adjacent ends of the two groups are magnetically connected. When the adjacent ends are close to each other, they are tightly attracted together by magnetic force to avoid lateral movement of the square rods 2328 during subsequent use, and the stability is good.
[0054] Advantage two, when the coupling tube 2331 is inserted into the sleeve 231, the magnetic block 2343 and the magnetic plate 2333 are quickly attracted, the inclined block 2332 pushes the triangular block 2334 and the coupling rod 2335 to slide outward, and the coupling rod 2335 is inserted into the ear block 2313, completing the instantaneous installation of the instant coupling part 233, the sleeve 231 and the magnetic part 234.
[0055] Advantage three, after installation, since the sleeve 231 is in a downward tilted state, the outer surface of the counterweight plate 2341 is always tightly fitted with the end face of the limit ring 2312 under the action of its own gravity, and the positions of the counterweight plate 2341 and the magnetic block 2343 and the magnetic plate 2333 remain unchanged due to the magnetic force between the magnetic block 2343 and the magnetic plate 2333, and the coupling rod 2335 on the instantaneous coupling 233 is always inserted in the ear block 2313, thereby improving the overall stability.
[0056] Advantage 4: When the instantaneous coupling member 233 and the lighting lamp body 24 need to be replaced or repaired, the tooth block 2329 is manually pulled away from the tooth plate 2325, and then the sleeve 231 is rotated upward (see Figure 5 As shown by the upward arrow in the figure, under the force of the maintenance personnel, the sleeve 231 is rotated from the bottom to the top in an inclined state). When the sleeve 231 is tilted upward, the counterweight plate 2341 drives the magnetic block 2343 to separate from the magnetic plate 2333 under the action of gravity, and the instantaneous coupling member 233 drives the coupling rod 2335 to separate from the ear block 2313 under the elastic force of its own return spring 2336, thereby completing the instantaneous disassembly of the lighting lamp body 24.
[0057] Advantage five: after long-term use, the elastic force of the reset spring 2336 is fatigued. At this time, the sleeve 231 is in an upward tilted state. Then, manually rotate the handle on the outside of the counterweight plate 2341 to rotate it 180 degrees to switch the positions of the two sets of magnetic blocks 2343. Then, rotate the sleeve 231 downward, and the magnetic block 2343 pushes the magnetic plate 2333 in the opposite direction, cooperating with the reset spring 2336 to accelerate the separation of the combining rod 2335 from the ear block 2313, completing the instantaneous disassembly of the lighting lamp body 24.
[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
