Description

Technical Field

[0070] The working principle of the present invention is as follows:

[0071] The lamp bead is inserted into the lamp holder 201 that matches it, and the two pins of the lamp bead are respectively inserted into the bent tube 202. The L-shape of the bent tube 202 can make the pins bend after insertion, so that in the absence of external force, the lamp bead can be automatically hung on the lamp holder mechanism 2 by bending the pins. During the installation and maintenance process, the lamp bead can remain stable and there is no need for personnel to weld or hold it, which improves the convenience of fixing the lamp bead.

[0072] Loosen the knob 407 to make the slider 405 slide along the first slide groove 402, so that the foot cover assembly extends through the first pressure cylinder 301 and the bent tube 202, and the pins of the lamp beads are correspondingly inserted into the foot cover 409, and the ends of the pins are clamped by the inner ball 413, and the pins and the foot cover assembly are inserted into the bent tube 202 together. At this time, the outer ball 412 is squeezed by the bent tube 202 and enters the through hole 410, and the deformation degree of the second spring 411 increases, so that the inner ball 413 clamps the pins tighter, so that after the pins are inserted into the bent tube 202, the buckle pins of the foot cover assembly are adaptively tightened to improve the stability of the lamp bead connection.

[0073] After the foot cover assembly locks the pin, the knobs 407 on both sides are pulled synchronously, so that the pin is driven to pass through the bent tube 202 and deform through the guide rope 408, and the end of the pin enters the first pressing cylinder 301. The foot cover assembly snaps on the pin and the guide rope 408 pulls the pin, so that the pin moves more smoothly in the fixing assembly, thereby improving the accuracy of lamp bead installation.

[0074] After the lamp bead is inserted into the lamp holder 201, the knob 407 is tightened to fix the slider 405. By observing the positions of the knobs 407 on both sides under the bar 401, the positions of the positive and negative pins of the lamp bead can be intuitively seen, thereby improving the visibility of the lamp bead connection.

[0075] After the lamp beads are installed in place, the lock buckles 505 are buckled on the connecting ring 604 in turn, and then the lamp cover 601 is movably connected to the back plate 101 through the buckles of the slot 102 and the clamping strip 602, and the lamp bead head is covered by the light guide column 607 to guide the light from the light guide column 607 to improve the illumination of the lamp beads.

[0076] By setting the adjustment mechanism 5 and snapping the lock buckle 505 and the connecting ring 604, the pull rope 504 is wrapped around the periphery of the lamp bead at a certain angle, so that the light source on the side of the lamp bead can be captured by the pull rope 504 and reflected and gathered, thereby improving the light source utilization rate of the lamp bead.

[0077] By snapping the connecting ring 604 and the locking buckle 505, the lampshade 601 is rotated along the back plate 101, so that the reflector 503 is pulled to rotate to different angles through the misalignment of the connecting ring 604 and the reflector 503, thereby changing the angle of the reflected light, and the irradiation range of the lamp beads can be adjusted, thereby improving the adjustability of the lamp bead lighting.

[0078] By rotating the cover plate 605, the inner rod 609 inserted on the push seat 608 is aligned with the embedding groove 308 of the second push column 307. Under the action of the third spring 610, the inner rod 609 is extended, and then guided by the second push column 307, the pressing plate 306 is inserted into the first pressing cylinder 301, further clamping and locking the pins of the lamp beads inserted into the pressing mechanism 3, thereby further locking the lamp beads and improving the fixing quality of the lamp beads.
