Assuming that the state that the first positioning pin extends into the positioning hole 110 from the first side of the positioning hole 110 is an initial state, at this time, the first connecting seat 100 and the second connecting seat 200 are locked with each other, the unlocking pin 400 is pressed, the unlocking pin 400 extends into the positioning hole 110 from the second side of the positioning hole 110, and the unlocking pin 400 drives the first positioning pin to compress the first elastic member until the first positioning pin withdraws from the positioning hole 110, the first connecting seat 100 and the second connecting seat 200 are unlocked, and then the second connecting seat 200 rotates relative to the first connecting seat 100, at this time, under the elastic action of the first elastic member, the other end face of the first positioning pin slides against the groove wall end face of the wire fixing groove 130, under the elastic action of the second elastic member, the other end face of the second positioning pin slides against the groove wall end face of the wire fixing groove 130, and when the second connecting seat 200 rotates 180 ° relative to the first connecting seat 100, the second positioning pin is coaxial with the positioning hole 110, at this time, the second elastic member rebounds and drives the second positioning pin to extend into the positioning hole 110 from the first side of the positioning hole 110, and the unlocking pin 400 is ejected out of the positioning hole 110 while the second positioning pin extends into the positioning hole 110, so that the first connecting seat 100 and the second connecting seat 200 are locked again. If the second connection seat 200 is rotated 180 degrees in the opposite direction, the unlocking pin 400 is pressed again, the second connection seat 200 is rotated in the opposite direction after the first connection seat 100 and the second connection seat 200 are unlocked until the second connection seat 200 rotates to the initial position, and the first positioning pin extends into the positioning hole 110 under the action of the first elastic member, so that the first connection seat 100 and the second connection seat 200 are locked in the initial position.
This embodiment still provides a lamps and lanterns, as shown in fig. 6, including two at least mounting brackets 1 and at least one foretell pivot subassembly 3, all install a mounting bracket on every first connecting seat 100 and every second connecting seat 200, install at least one fluorescent tube 2 on every mounting bracket 1, realize the folding function of rotation of lamps and lanterns mounting bracket 1 from this, not only can rotate the angle between fluorescent tube 2 and the fluorescent tube 2 according to the user demand, whole volume when can also effectively reducing lamps and lanterns and depositing, when mounting bracket 1 rotates to the locking position with mounting bracket 1, its two locking reliability is higher, can avoid the fluorescent tube 2 that leads to because the locking is lost efficacy and collide with the scheduling problem.
Further, as shown in fig. 6, in the technical scheme provided in this embodiment, the lamp further includes a wire accommodating box 4, the two sides of the wire accommodating box 4 are respectively and fixedly connected with the mounting rack 1 of the rotating shaft assembly 3, so that the lamp can be folded in both sides of the wire accommodating box 4, the overall size of the folded lamp is effectively reduced, and then the effects of saving the package size of the lamp, reducing the package cost, facilitating taking, facilitating transportation, facilitating installation and the like are brought.
The lamps and lanterns that this embodiment provided, can hold box 4's both sides at the wire and all fold lamps and lanterns, the volume of lamps and lanterns has effectively been reduced, and, through respectively establish an holding tank 210, a locating pin 300 and an elastic component in the top and the bottom of second connecting seat 200, make lamps and lanterns expand completely under the effect of elastic component, locating pin 300 stretches into locating hole 110 automatically, realize that lamps and lanterns expand the effect of usefulness immediately (namely, form automatic fixation when lamps and lanterns expand the state), make things convenient for the use and the installation of lamps and lanterns.
