Description

Rotating system and fixture with rotating system

The present invention relates to a rotating system, and more particularly to a fixing device having a rotating system.

Existing rotating systems typically include a fixture and a rotating member that is rotatably secured to the fixture. The rotating member is rotatable relative to the fixing member between two predetermined positions when subjected to a force. However, during the rotation, the user will find that when the rotating member is rotated to a position, the rotating member continues to rotate relative to the fixed member, thereby causing the rotation system to be unstable. Therefore, it is necessary to provide a stable rotation system.

In view of this, it is necessary to provide a rotating system that is stable in operation.

In addition, it is also necessary to provide a stationary device that is stable in operation.

A rotating system includes a fixing member, a rotating member rotatably mounted on the fixing member, and a torsion spring, wherein both ends of the torsion spring are respectively fixed to the fixing member and the rotating member, the torsion spring The windings are freely set.

A fixing device for fixing an electronic device, the fixing device comprising a fixing member having a through hole, and being fixed to the fixing member for hooking the electronic device a hooking member in the card slot of the device, a locking member rotatably fixed to the fixing member, and a rotating member rotatably mounted on the fixing member, the locking member is convexly disposed to pass through The through hole is inserted into the lock block in the card slot, and the rotating member drives the hook member to rotate when rotating, so that the lock block is inserted into the card slot or from the The fixing device further includes a torsion spring, the two ends of the torsion spring are respectively fixed on the fixing member and the rotating member, and the winding of the torsion spring is freely disposed to prevent the rotation The piece rotates when the lock block is inserted into the card slot or is retracted from the card slot.

Since the above-mentioned rotating system is provided with a torsion spring which is freely disposed by the winding, when the rotating member is rotated to one of two predetermined positions, the rotating member is stably stopped at the position by the action of the torsion spring, and therefore, Ensure the stability of the rotating system.
