Anti-loose rotation device for car rearview mirror

Abstract

The invention discloses an automobile rearview mirror anti-loosening rotation device, which comprises a mirror frame, a mirror rod, a mirror base, a limit mechanism, a fixing seat, a bolt and a plane bearing. The mirror rod is connected to the fixing seat, and the fixing seat is installed on the mirror base. On the support surface of the fixed base, a through-limiting hole is provided in the fixed seat; a cylindrical through hole is provided in the mirror base; the limiting mechanism includes a limiting block and a connecting column, and the connecting column and the limiting block are fixed as In one body, there is a non-cylindrical body on the connecting column, and a threaded hole is provided in the non-cylindrical body. The connecting column passes through the mounting hole of the plane bearing and the cylindrical through hole of the mirror base, and the non-cylindrical body on the upper part and the limit hole of the fixed seat Cooperate, and connect the limit block, the mirror base and the fixed seat through the cooperation of the bolts and the non-cylindrical threaded holes. Its remarkable effect is that the rearview mirror will not loosen with the increase of the number of times of pulling, and the pulling force of the mirror rod can be adjusted by controlling the tightness of the bolt. At the same time, the assembly is convenient, and special tools are not required for installation and disassembly.

Description

technical field [0001] The invention relates to an automobile rearview mirror, in particular to an automobile rearview mirror loosening and rotating device. Background technique [0002] The rearview mirror is an important part of the car, which directly affects the safety of the car. Therefore, it is very important to ensure the stability of the rearview mirror. [0003] Usually, the rearview mirror of automobile comprises picture frame, mirror bar and mirror base, and picture frame is used for installing rearview mirror, and mirror bar is used for supporting picture frame, and mirror base is used for fixing mirror bar, and mirror base is fixed on the corresponding position of automobile body. Wherein, the lower pole of the mirror rod is fixed in the mirror base, and the lower pole includes at least one irregular surface. At the same time, a limit block is arranged in the mirror base. The regular surface is clamped tightly on the limit block to prevent the rotation of the ...

AI Technical Summary

Problems solved by technology

[0004] The deficiencies of the above-mentioned prior art mainly include the following aspects: (1): With the increase of the number of pulls, the elastic force of the spring decreases, so that the irregular surface of the lower pole of the mirror pole cannot be re-clamped to the limit block On the road, it is easy to cause the rotation of the rearview mirror, which will affect the normal driving of the car, and even cause a car accident in severe cases;

[0005] (2): Since the rotation of the rearview mirror is mainly achieved by the rotation of the lower pole of the mirror pole in the mirror base, when the lower pole rotates in the mirror base, it will inevitably cause irregular surfaces of the mirror base and the lower pole The wear and tear of the rearview mirror will cause the loosening of the rearview mirror, which will affect the normal use of the rearview mirror;

[0006](3): Complex structure, inconvenient installation and disassembly, special tooling is required for installation and disassembly
