Description

Technical Field

[0001] The utility model belongs to the technical field of track lights, and in particular relates to a novel multifunctional gear transmission mechanism. Background Art

[0002] Track lights are a type of light that uses LED as a light source and are widely used in key lighting locations. The notable feature of track lights is that they can be moved on tracks and the direction of illumination can be changed through a transmission mechanism.

[0003] After searching, the Chinese publication (announcement) is CN208546858U, which proposes an adjustable angle track light, including a connection frame, a top plate fixedly mounted on the top of the connection frame, a mounting seat fixedly mounted on the lower surface of the top plate, plug-in rods fixedly connected to the lower surface of the mounting seat, and four shading plates are independently rotated manually to change the width of the opening formed between the four shading plates, thereby adjusting the illumination angle of the track light, thereby achieving the purpose of convenient adjustment;

[0004] Existing track lights, such as the above-mentioned adjustable angle track lights, can adjust the illumination angle of the track lights. However, since the track lights are mostly installed at high places to illuminate the lighting places, when the illumination angle of the track lights needs to be adjusted, it is necessary to climb up to the high place to manually adjust the illumination angle of the track lights, which is inconvenient to adjust the illumination angle of the track lights. Utility Model Content

[0005] The purpose of the utility model is to provide a novel multifunctional gear transmission mechanism to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: Based on the base, transmission assembly and shell, the utility model is characterized in that the base is detachably connected and installed at the bottom of the shell with a hollow screw. The hollow screw is arranged in the shell, and the bottom is connected to the center of the base. The top of the hollow screw protrudes through the shell. The bottom of the hollow screw is fixedly connected to a driven gear and a transmission assembly for driving the hollow screw to rotate is arranged on one side of the driven gear. The power output end of the transmission assembly is connected to the driven gear. A threading groove is arranged in the hollow screw. The shell and the base are connected by bolts, which is convenient for later disassembly to repair the internal transmission assembly.

[0007] The transmission assembly of the utility model includes a motor, a first gear group, a second gear group, and a third gear group. The motor is fixedly installed on the base. The transmission shaft of the motor passes through the shell and extends into the shell. The transmission shaft in the shell is fixed with a worm, and the first gear group of the transmission assembly is meshed with the worm.

[0008] The first gear set, the second gear set and the third gear set described in the utility model are respectively composed of two large and small gears coaxially connected in series.

[0009] The utility model comprises a large gear of the first gear group meshing with the worm of the motor, a small gear of the first gear group meshing with the large gear of the second gear group, a small gear of the second gear group meshing with the large gear of the third gear group, and a small gear of the third gear group meshing with the driven gear.

[0010] The working principle of the utility model is that when the track light adjusts the illumination angle, the motor can be rotated to drive the worm to rotate, the worm drives the first gear group meshing with it to rotate, the first gear group drives the second gear group to rotate, and the second gear group rotates while sequentially driving the third gear group meshing with each other, and the rotation of the third gear group drives the driven gear meshing with it to rotate, thereby driving the hollow screw fixed on the driven gear to rotate, and the illumination angle of the track light is adjusted. Because a wire threading groove is provided in the hollow screw, the wire threading groove is provided in the middle of the hollow screw, and the line connection is connected to related components through the wire threading groove, which avoids the exposure of the wire body and affects the movement of the track light, and is convenient for the wire body to pass through when adjusting, and there is no need for manual adjustment.

[0011] The technical effects and advantages of the utility model are as follows: the novel multifunctional gear transmission mechanism comprises a base, which is installed on a track when in use, the track light is installed with a hollow screw, and the wires on the track light can pass through the wire grooves in the hollow screw, thereby preventing the wires from being exposed and affecting the movement of the track light.
