A quick-release device for a motorcycle tank bag, comprising:
- a quick-release main body;
- a base plate;
- and
- a tank cap mounting unit;
- wherein the base plate is configured to be connected to a tank bag, and mount the tank bag;
- the tank cap mounting unit is configured to be fixedly connected to an edge of a port of a motorcycle tank;
- the tank cap mounting unit is provided with a fastening hole;
- the quick-release main body comprises a housing, and a latch assembly arranged in the housing;
- a bottom of the housing is provided with a U-shaped groove configured to mount the tank cap mounting unit, and a side wall of the U-shaped groove is provided with a plurality of through holes;
- the latch assembly comprises an active latch plate, a driven latch plate, an operating component and at least one first return spring;
- the active latch plate and the driven latch plate are slidably arranged in the housing;
- the operating component is configured to drive the active latch plate and the driven latch plate to move;
- and the at least one first return spring is configured to abut against the active latch plate and the driven latch plate;
- an outer end of each of the active latch plate and the driven latch plate is provided with a fastening head;
- a synchronization gear is rotatably arranged in the housing;
- and an inner end of each of the active latch plate and the driven latch plate is provided with a rack;
- the rack is configured to engage with the synchronization gear, such that when the operating component drives the active latch plate to move, the synchronization gear drives the driven latch plate to move synchronously, and the fastening head is driven to retract from or extend out of the plurality of through holes to be clamped within the fastening hole to achieve locking;
- the operating component comprises a rotation shaft, an actuating lever and an inner pivot arm;
- the rotation shaft is rotatably arranged on the housing;
- the actuating lever is arranged outside the housing;
- and the inner pivot arm is arranged inside the housing;
- in response to a case that an external force is applied to the actuating lever, the operating component is configured to rotate about the rotation shaft, so as to directly or indirectly drive the active latch plate and the driven latch plate to move toward each other via the inner pivot arm, thereby causing the fastening head to retract into the housing;
- and
- in response to a case that the external force is removed, the at least one first return spring is configured to offer an elastic force to drive the active latch plate and the driven latch plate to move away from each other, thereby causing the fastening head to extend out of the housing to be clamped within the fastening hole to achieve locking.
