Abstract

A fixing device with a rotation locking mechanism includes a fixing device body, a pivot element, a locking member and a spring. The fixing device body has an accommodating space for accommodating the portable electronic device. The pivot component includes a female shaft component, a male shaft component and a driving cam. The female shaft part is fixedly connected to the fixing device body; the male shaft part is pivotally connected to the female shaft part and is used to be fixedly connected to the functional seat; the driving cam is arranged on the male shaft part. The locking piece is movably disposed in the fixing device body and has a hook part and a driven part. The spring pushes the locking member to move in the reverse direction of the hook to an unlocking position. Among them, the driving cam drives the locking member to move from the unlocking position to a locking position through the relative rotation of the male shaft member and the female shaft member, thereby causing the hook portion to hook into the locking groove. This provides users with more convenient operation performance, and makes the portable electronic device more stable and prevents it from slipping due to the engagement of the hook when closing.

Description

Fixtures with turn-and-lock mechanism

technical field

The utility model relates to a fixing device with a rotation locking mechanism, in particular to a fixing device with a rotation locking mechanism which utilizes the rotation of a cam to drive a locking piece to engage with a portable electronic device.

Background technique

In recent years, due to the rapid popularization of smart phones, portable electronic devices such as tablet computers have flourished, and tablet computers have developed technologies that can be combined with other additional devices such as keyboards.
