In using the cam-type handy lock 100, please refer to fig. 2 and 12, the cam-type handy lock 100 is shown in a locked state in fig. 2, and the cam-type handy lock 100 is shown in an unlocked state in fig. 12. Taking the initial state as the unlocked state as an example:

in the unlocked state, the centerline of the lobe 121 is generally in a horizontal plane with the plane of the axial configuration of the cam 120. The following describes a process of transitioning from the unlocked state to the locked state. Firstly, the rotating part 112 of the handle 110 is manually operated to release the self-locking of the handle 110, the cam 120 is driven to rotate by the rotating part 112, the axis of the cam 120 is kept still when the cam 120 rotates, the convex part 121 gradually abuts against the side wall of the rotating hole 130a in the rotating process, and finally, the central line of the convex part 121 and the plane of the axis structure of the cam 120 are approximately in the position of a vertical plane. During the rotation of the cam 120, the convex part 121 pushes the connecting rod assembly block 130 to move away from the female buckle 20, and since the lock rod 141 is fixed in the through groove 130b, the movement of the connecting rod assembly block 130 drives the locking buckle 140 to move away from the female buckle 20; when the lock lever 141 moves, the lock lever has a tendency to drive the torsion spring 150 to move, the torsion spring 150 tightens, accumulates torsion, and pushes the fastener 143 to rotate in the tightening process, and the fastener 143 is fastened on the female buckle 20.

In the locked state, the lock rod 141 compresses the elastic member 170 through the top pillar 160, when the locked state is changed to the unlocked state, the handle 110 is operated to release the self-locking of the handle 110, the rotating member 112 drives the cam 120 to rotate, so that the plane formed by the center line of the protrusion 121 and the axis of the cam 120 rotates from the vertical plane to the horizontal plane, in the rotating process of the cam 120, the protrusion 121 gradually releases the abutting against the link assembly block 130, under the action of the elastic member 170, the top pillar 160 has a tendency of pushing the lock rod 141 to move, and finally the lock buckle 140 and the link assembly block 130 are pushed to move towards the direction close to the female buckle 20, the torsion of the torsion spring 150 is released, the lock buckle 140 is pushed to rotate reversely, and the fastener 143 is disengaged from the female buckle 20. Since the locking button 140 is relatively close to the female button 20 during the movement, the fastening member 143 can be easily disengaged from the female button 20. After the locking buckle 140 rotates a certain angle, the rotation-stopping top column 163 enters the second groove 141a of the locking rod 141, the shifting ball 191 enters the concave hole 140b of the fastener 143, and the locking buckle 140 does not move any more, so that the two box bodies can be easily separated.

According to the cam-type convenient lock 100, the handle 110, the cam 120 and the connecting rod assembly block 130 are arranged, the rotation of the handle 110 drives the convex part 121 of the cam 120 to rotate in the rotating hole 130a of the connecting rod assembly block 130, and due to the existence of the convex part 121 of the cam 120, when the cam 120 rotates, the connecting rod assembly block 130 moves relative to the female buckle 20 along with the change of the abutting relation between the convex part 121 and the connecting rod assembly block 130, and is relatively close to or far away from the female buckle 20. When the connecting rod assembly block 130 moves, the torsion spring 150 drives the locking buckle 140 to rotate, so as to be buckled with or separated from the female buckle 20, and the operation of the handle 110 realizes the linkage of the locking buckle 140 without multiple operations. By abutting the top pillar 160 against the locking buckle 140, when the locking buckle 140 moves along with the connecting-rod assembly block 130, the elastic member 170 provides an acting force to the locking buckle 140, so that the locking buckle 140 and the female buckle 20 maintain locked, and a restoring force is provided for the resetting of the connecting-rod assembly block 130 and the locking buckle 140. The design of the torsion spring 150 provides a driving force for the rotation of the locking buckle 140 when the locking buckle 140 moves along with the link assembly block 130, so as to ensure that the locking buckle 140 and the female buckle 20 keep a sufficient buckling force, and prevent the locking buckle 140 and the female buckle 20 from being separated to disconnect the box body when no external force acts on the handle 110 by the locking buckle 140. Therefore, the cam-type portable lockset 100 can realize convenient operation and can ensure that the box bodies are stably spliced. When the locking state and the unlocking state are switched, only the simple operation of manually rotating the handle 110 is needed, and the subsequent unlocking and locking processes are completed by automatic linkage of all parts, so that one-step operation unlocking and one-step locking are realized.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
