US 12,599,287 B2 · Self-locking device of endoscope

Abstract

A self-locking device of an endoscope includes a connecting assembly and a fitting assembly. The connecting assembly includes a driven gear and a toggle lever, and the driven gear and the toggle lever are fitted with each other through pins. The fitting assembly includes a driving gear, and the driving gear is engaged with the driven gear through the toggle lever. The self-locking device realizes self-locking with a desired effect through the engagement of the driven gear and the driving gear. Through the design of a lever structure, the self-locking device switches the driven gear and the driving gear between engaged and disengaged states without resorting to an external force of a part, which avoids the use of the part and extends the service life of the device.

Dependent claims

A self-locking device of an endoscope, comprising:

a connecting assembly, comprising a driven gear and a toggle lever, wherein the driven gear and the toggle lever are fitted with each other through pins;
and
a fitting assembly, comprising a driving gear, wherein the driving gear is engaged with the driven gear through the toggle lever;
wherein the driven gear comprises limiting holes having an arc-shaped cross section, and the toggle lever comprises a gear connecting block provided with connecting holes,
wherein the pins pass through the arc-shaped limiting holes and the connecting holes and are configured to enable the toggle lever to rotate along a curved path defined by the arc-shaped limiting holes as the toggle lever transitions the driving gear and the driven gear between a self-locking state and a non-self-locking state.
