Description

Technical Field

[0001] The utility model relates to the technical field of motor vehicle lighting, in particular to a plastic ball head for a dimming motor. Background Technique

[0002] A plastic ball head is a component widely used in the mechanical and industrial fields. Its design allows it to achieve flexible movement and adjustment between connecting components. Made of plastic material, the ball head is relatively light in weight, which helps to reduce the burden on the overall mechanical structure.

[0003] However, during the rotation of the ball head and the connecting components, there will be wear. Long-term rotation will cause the connection to become loose. At this time, only the entire ball head can be replaced and updated, which is not convenient for the long-term use of the dimming motor.

[0004] To solve the above problems, we propose a plastic ball head for a dimming motor. Content of the Utility Model

[0005] The utility model is a plastic ball head for a dimming motor proposed to solve the problems in the background technique.

[0006] To achieve the above object, the utility model adopts the following technical scheme: A plastic ball head for a dimming motor includes a circular tube. A circular block is fixedly inserted at the right end of the circular tube. Four horizontally arranged plastic rods are fixedly connected to the left end of the block and extend to the left side of the circular tube. The four plastic rods are rotationally symmetric about the center of the block. Plastic ball blocks are fixedly connected to the left ends of the four plastic rods. A sliding column located at the right end of the block and between the four plastic rods is slidably inserted into the circular tube. A horizontally arranged sliding groove is formed on the outer side wall of the circular tube and is located between two adjacent plastic rods. A pushing block is fixedly arranged on the outer side wall of the sliding column and is slidably inserted into the sliding groove. A fastening sleeve is slidably sleeved on the outer side walls of the four plastic rods and is located between the left end of the circular tube and the plastic ball blocks.

[0007] A horizontally arranged threaded rod is fixedly connected to the right end of the circular tube. The left end of the threaded rod is in contact with the right end of the block. A fixed rod having the same outer diameter as the threaded rod is fixedly arranged at the right end of the threaded rod. A support rod is fixedly connected to the right end of the fixed rod. The outer side wall of the support rod and the outer side wall of the fixed rod are at the same height and have the same curvature. An insertion block is fixedly connected to the right end of the fixed rod and is arranged opposite to the support rod. A ring sleeve is fixedly connected to the right end of the support rod. The ring sleeve is crescent-shaped and the notch position is directly above the insertion block.

[0008] In the above-mentioned plastic ball head for a dimming motor, circular holes that communicate with each other are formed in the block, the threaded rod, and the fixed rod. The left end of the circular hole is located in the middle of the four plastic rods and does not contact the four plastic rods.

[0009] In the above-mentioned plastic ball head for a dimming motor, the ends of the four plastic rods that are close to each other are all arranged in an arc shape.

[0010] In the above-mentioned plastic ball head for a dimming motor, the sliding column is arranged in a cross shape, and inclined arc surfaces are arranged between adjacent ends. The width of the cross-shaped end surface at the left end of the sliding column is smaller than the width of the cross-shaped end surface at the right end of the sliding column.

[0011] In the above-mentioned plastic ball head for a dimming motor, the inner diameter of the left port of the fastening sleeve is smaller than the inner diameter of the right port of the fastening sleeve.

[0012] In the above-mentioned plastic ball head for a dimming motor, the length of the insertion block is smaller than the length of the support rod. The widths of the support rod and the insertion block are the same as the width of the circular ring surface of the ring sleeve and both have the same radian.

[0013] Compared with the existing technology, the advantages of the plastic ball head for a dimming motor of the present utility model are as follows:

[0014] The present utility model can adjust the ball head when the ball head and the connecting piece are loose, so that it can reach a certain tightness, complete the auxiliary function for the dimming motor, and the middle periphery is also provided with threads, which can match the transmission wheel during the assembly of the motor.
