Description

Technical Field

[0001] This utility model belongs to the field of LED bracket technology, specifically relating to an adjustable angle fixing device for LED brackets. Background Technology

[0002] LED brackets are used to install LED lights and serve as support mechanisms in various locations. However, in existing technologies, LED light brackets are generally fixed at an angle or require manual adjustment of the LED light bracket angle. This makes adjusting the LED light illumination range very inconvenient and also fails to achieve continuous angle adjustment.

[0003] In an LED bracket with adjustable illumination angle disclosed in CN221780630U, a support structure is set on the base assembly. The sliding column of the support structure has an integral locking part in the middle. An adjusting sleeve is fitted over the sliding column. The adjusting sleeve has a mounting bracket for mounting the lighting assembly. The adjusting sleeve has a locking cavity and rotating cavities at both ends of the locking cavity. The adjusting sleeve can slide along the axial direction of the sliding column. When the locking part is in the locking cavity, the locking part and the locking cavity lock together, so that the adjusting sleeve and the sliding column stop rotating from each other. When the locking part is in the rotating cavity, the adjusting sleeve and the sliding column rotate together. It has the effect of adjustable illumination angle and convenient angle adjustment. However, the above patent can only adjust the pitch angle of the bracket, and the angle of the bracket needs to be manually adjusted, so it cannot achieve the technical effect of convenient angle adjustment. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable angle fixing device for LED brackets, so as to solve the problem in the background art that only the pitch angle of the bracket can be adjusted, which requires manual adjustment of the bracket angle and is inconvenient to adjust the angle.

The end of the second support rod away from the first support rod is hinged to the third support rod. The end of the third support rod away from the second support rod is connected to the second mounting plate through the pitch adjustment mechanism. The height adjustment mechanism drives the second support rod to move relative to the first support rod. The left-right adjustment mechanism drives the third support rod to move left and right relative to the second support rod. The pitch adjustment mechanism drives the second mounting plate to perform an arc-shaped movement.

The output end of the first motor is connected to the first lead screw, the first lead screw nut seat is sleeved on the first lead screw, one end of the first connecting rod is hinged to the first lead screw nut seat, and the other end is hinged to the second support rod.

[0007] Preferably, the left and right adjustment mechanism includes a second motor, a second lead screw, a second lead screw nut seat, a second connecting rod, and a fixed rod. The output end of the second motor is connected to the second lead screw. The second lead screw nut seat is sleeved on the second lead screw. The fixed rod is fixed to the end of the third support rod away from the second support rod. One end of the second connecting rod is hinged to the second lead screw nut seat, and the other end is hinged to the fixed rod.

[0008] Preferably, the pitch adjustment mechanism includes a fixed base, a movable base, a gear, and a dual-axis motor. The movable base moves in an arc relative to the fixed base.
