Single-point low-profile locking ring for mechanical seals
The mechanical seal uses a locking ring assembly with an associated locking mechanism. The locking mechanism can include a nut element, such as a barrel nut, that allows adjustment of the clamping load and position of the associated bolt element when clamping the mechanical seal components. This adjustment flexibility eliminates or reduces unnecessary bending stress on the bolt element, allowing greater torque to be transferred directly to the locking ring. The barrel nut allows more material to remain in the locking ring, adding overall strength compared to conventional locking elements. Additionally, the locking ring includes multiple notched bending regions that allow the locking ring to flex as the body is tightened around the shaft.

Camera module and single-point actuator
The present invention discloses a single-point actuator, which includes a fixed end, a movable end, and an SMA wire. The movable end has an elastic structure. The two ends of the SMA wire are respectively connected to the fixed end and the movable end. When the SMA wire is energized and shrinks, it drives the movable end to move. When the SMA wire is de-energized, the movable end can reset under the action of its own elastic force. The single-point actuator of the present invention has only one movable end. The moving stroke of the movable end driven by the contraction of the SMA wire when it is energized is twice that of the prior art when driving two movable ends to move. Therefore, the present invention enables the movable end to have a larger moving stroke, can drive the object to be moved to generate a larger stroke, thereby achieving a larger angle adjustment and improving the adjustment accuracy. By utilizing the characteristic of the SMA wire to shrink when heated to obtain the actuation function, the structure of the single-point actuator is simplified, and the requirements for product miniaturization can be met. The present invention also discloses a camera module having a single-point actuator.
