Embodiments of the utility model are described below with reference to the accompanying drawings:

referring to fig. 1 to 4, the limiting device of the embodiment of the application includes a first fixing base 100, a second fixing base 200, a connecting device 300, a locking member 400, and a limiting member 500, where the first fixing base 100 is provided with a mounting hole 110 along a first direction, the second fixing base 200 is located at one side of the first fixing base 100 along the first direction, the second fixing base 200 is provided with a limiting region 210 facing the first fixing base 100, the limiting member 500 is disposed between the first fixing base 100 and the limiting region 210, the limiting member 500 includes a first limiting end 510 mounted facing the first fixing base 100 and a second limiting end 520 mounted facing the limiting region 210, and the first limiting end 510 and the second limiting end 520 can mutually cooperate to limit relative rotation between the limiting member 500 and the first fixing base 100, and the locking member 400 is disposed in the mounting hole 110 along the first direction in a penetrating manner and cooperates with the mounting hole 110.

The connecting device 300 includes a first connecting member 310 and a second connecting member 320, the second connecting member 320 extends along a first direction, the connecting device 300 has a locked state and an unlocked state, when in the locked state, the first connecting member 310 and the second connecting member 320 are locked through connection, so that the first connecting member 310 moves along the first direction to abut against the locking member 400, the locking member 400 abuts against the first limiting end 510 of the limiting member 500, the second limiting end 520 of the limiting member 500 abuts against the second fixing seat 200, and the second limiting end 520 can be matched with the limiting area 210 on the second fixing seat 200, thereby limiting the relative rotation between the limiting member 500 and the second fixing seat 200.

Further, when the first connector 310 releases the connection with the second connector 320, the connector 300 is in the unlocked state, and the first connector 310 releases the holding of the locking member 400, so that the holding of the locking member 400 on the limiting member 500 along the first direction is released, and the limiting member 500 can move between the locking member 400 and the limiting region 210 along the first direction.

Therefore, in the unlocking state, the first fixing seat 100 and the second fixing seat 200 can relatively rotate to realize angle adjustment, and when rotating, the limiting area 210 on the second fixing seat 200 can push the second limiting end 520 along the first direction, so that the limiting piece 500 is far away from the limiting area 210 of the second fixing seat 200 along the first direction, and mutual interference between the second limiting end 520 and the limiting area 210 can be avoided in the process of continuously rotating to adjust the angle, so that abrasion between the second limiting end 520 and the limiting area 210 is reduced, the lamp body 600 is connected with the second fixing seat 200, and the irradiation angle of the lamp body 600 is changed due to the relative rotation between the first fixing seat 100 and the second fixing seat 200, so that the requirement of adjusting the irradiation angle of the lamp light in daily life is met.

It is conceivable that the actual maximum movement amount of the limiting member 500 along the first direction is from the limiting area 210 of the second fixing base 200 to the surface of the first fixing base 100 facing the limiting member 500, when the limiting member 500 has the maximum movement amount along the first direction, the end surface of the locking member 400 facing the limiting member 500 is recessed relative to the end surface of the first fixing base 100 facing the limiting member 500, and it should be noted that the first connecting member 310 and the second connecting member 320 may be completely separated from each other in the unlocked state, and may also maintain the connected relationship, so long as the first connecting member 310 cannot prevent the locking member 400 from moving along the first direction, and when the locked state is changed from the locked state to the unlocked state, the first connecting member 310 moves relative to the second connecting member 320 along the first direction.

When the connecting device 300 is in the unlocking state, the limiting piece 500 is separated from the second fixing seat 200, so that the limiting piece 500 and the second fixing seat 200 can rotate relatively, the angle between the first fixing seat 100 and the second fixing seat 200 can be adjusted, and as the locking piece 400 can move along the first direction in the unlocking state and a sufficient gap for the limiting piece 500 to separate is reserved between the first fixing seat 100 and the second fixing seat 200 along the first direction, the separation of the limiting piece 500 and the second fixing seat 200 is relatively complete, the abrasion problem between the limiting piece 500 and the second fixing seat 200 when the angle of the limiting device is adjusted is effectively reduced, the adjustment failure problem caused by continuous abrasion between the limiting piece 500 and the second fixing seat 200 when the angle of the limiting device is adjusted for a long time is improved, and the service life of the limiting device is prolonged.
