Embodiment Construction

[0011] Combine below Figure 4 , describe the implementation of the present invention in detail.

[0012] Such as figure 1 As shown, the rotary cam lock is composed of lock cylinder 2, lock housing 3, No. 1 lock nut 4, rotary tongue plate 5, elastic steel sheet 6, and No. 2 lock nut 7. Its main structural feature is that, relying on the elastic force of the elastic steel sheet 6, the hook on the turning tongue 5 is inserted into the opening groove of the key 1 under the condition of no external force.

[0013] In actual operation, when the key 1 is inserted into the rotary cam lock, the top part of the key is in contact with the hook of the rotary tongue, and as the key goes deeper, it overcomes the elastic force of the elastic steel sheet 6 on the rotary tongue 5 and inserts it to the end.

Abstract

The invention relates to common cam locks for cabinets, in particular to a novel carelessness-preventive cam lock. The novel carelessness-preventive cam lock comprises a lock cylinder 2, a lock shell 3, a mounting locking nut 4, a cam 5, an elastic steel piece 6 and a locking nut 7. The novel carelessness-preventive cam lock is structurally characterized in that due to elastic force of the elastic steel piece 6, a fastening hook on the cam 5 is inserted in an open slot of a key 1 without external force. The fastening hook extends out of the cam and penetrates arc-shaped notches of the lock shell and the lock cylinder to be fastened in a notch of the key. The elastic steel piece is mounted on the cam, and the cam can slide on the lock cylinder by the elastic force of the elastic steel piece. When the cabinet in an unlocking or 'fake locking' state, the fastening hook of the cam is forcedly fastened in the notch of the key by the elastic force of the elastic steel piece, and the key cannot be pulled out at this moment; when the cam is screwed into a cabinet, the top of the cam contacts with the cabinet slowly and overcomes the elastic force of the elastic steel piece gradually; when the cabinet is in a completely locking state, the fastening hook of the cam is separated from the notch of the key, and the key can be pulled out at this moment.
