Loosening and rotating preventing device for rearview mirror of automobile

Abstract

The invention discloses a loosening and rotating preventing device for a rearview mirror of an automobile. The device comprises a mirror frame, a mirror rod, a mirror base, a limiting mechanism, a fixing base, a bolt and a plane bearing, wherein the mirror rod is connected to the fixing base; the fixing base is mounted on a supporting surface of the mirror base; a penetrating limiting hole is formed in the fixing base; a cylindrical through hole is formed in the mirror base; the limiting mechanism comprises a limiting block and a connecting pillar; the connecting pillar and the limiting block are fixedly connected into a whole; a non-cylindrical body is arranged on the connecting pillar; a threaded hole is formed in the non-cylindrical body; the connecting pillar passes through a mounting hole of the plane bearing and the cylindrical through hole of the mirror base; the non-cylindrical body on the upper part of the connecting pillar is matched with the limiting hole of the fixing base; and the limiting block, the mirror base and the fixing base are connected to each other, under a matching effect of the bolt and the threaded hole of the non-cylindrical body. The loosening and rotating preventing device has the beneficial effects that the rearview mirror is free from being loosened following the increasing of pulling times, a pulling force of the mirror rod can be adjusted in the manner of adjusting the tightness of the bolt, the assembling is convenient and no special tool is needed for assembling and disassembling.

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): As the number of pulls increases, the elastic force of the spring decreases, so that the mirror lever The irregular surface of the lower pole cannot be re-clamped to the limit block, which will easily cause the rotation of the rearview mirror, 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, the lower pole is in the mirror base When turning, it will inevitably cause wear on the irregular surface of the mirror base and the lower support rod, and then cause the rearview mirror to loosen, 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
