Angle adjustment mechanism (I)

Abstract

This invention provides an angle adjustment mechanism, which is pivotally mounted on a mirror base. It mainly includes: a locking tooth portion, a pivot member, and an elastic member. The locking tooth portion has multiple locking grooves. The pivot member is pivotally connected to the locking tooth portion. The elastic member is located inside the pivot member, and its front end has a locking protrusion that engages with one of the locking grooves. An elastic connecting arm is connected between the front and rear ends of the elastic member, thereby allowing the pivot member to pivot relative to the mirror base. This causes the locking protrusion to engage with another locking groove as it moves, thus fixing the locking protrusion and adjusting the angle position of the pivot member relative to the mirror base.

Claims

1. An angle adjustment mechanism, which is pivotally mounted at the end of a lens body, the angle adjustment mechanism mainly comprising: The device comprises a locking tooth, a pivot member, and an elastic member. The locking tooth has multiple locking grooves. The pivot member is pivotally connected to the locking tooth. The elastic member is located inside the pivot member and has a locking protrusion at its front end. The locking protrusion engages with one of the locking grooves. An elastic connecting arm is connected between the front and rear ends of the elastic member. When the pivot member is operated to pivot up and down relative to the mirror body, the elastic connecting arm is elastically contracted under force, causing the locking protrusion to engage with the locking groove at another segment and become fixed, thereby adjusting the angle position of the pivot member relative to the mirror body.

2. The angle adjustment mechanism as described in claim 1, wherein the locking teeth extend from the end of the mirror body.

3. The angle adjustment mechanism as described in claim 1, wherein the pivot member has an accommodating space inside, the opening of the accommodating space faces the locking tooth portion, and the elastic member is disposed within the accommodating space.

4. The angle adjustment mechanism as described in claim 1, wherein the resilient connecting arm has at least one angled turning portion.

5. The angle adjustment mechanism as described in claim 1, wherein the number of the elastic connecting arms is two, which are arranged at an upper and lower interval or symmetrically arranged at an upper and lower angle.
