Abstract
The present utility model discloses a safety lock device including a first lock body and a second lock body. The first lock body is provided with a movable member, a first action member and a second action member. The second action member and the first action member are operated sequentially to enable the movable member to act to unlock. The first action member or the second action member is operated individually that cannot achieve the unlocking. The unlocking of the safety lock device is completed only by fitting the two moving members with each other, thereby solving the problems of the easy unlocking by children and the potential safety hazards.

A safety lock device, comprising:
- a first lock body,
- a second lock body, and
- a movable member, the movable member being telescopically disposed on the first lock body, and at least a part of the movable member being disposed in a lock hole of the second lock body to lock the first lock body and the second lock body when the movable member extends out;
- wherein the first lock body comprises a first action member and a second action member, and the movable member comprises a first fitting member and a second fitting member, and the second fitting member comprises a first unlocking part and a second unlocking part;
- the first action member acts on the first unlocking part so as not to drive the movable member, the first action member acts on the second unlocking part so as to drive the movable member to act to unlock from the lock hole, and the second action member acts on the first fitting member so as not to drive the movable member to be completely separated from the lock hole;
- in an initial situation, the first action member is located at a position corresponding to the first unlocking part;
- and
- when unlocking, the second action member acts on the first fitting member to drive the movable member to act, such that the first action member is transformed from corresponding to the first unlocking part to corresponding to the second unlocking part, and the first action member acts on the second unlocking part so as to drive the movable member to act to unlock from the lock hole.
A safety lock device comprising a first lock body and a movable member, wherein the movable member is telescopically fitted on the first lock body, and the safety lock device is in a locked state when at least a part of the movable member extends out of the first lock body,
- the first lock body further comprises a first action member and a second action member, the movable member comprises a first fitting member and a second fitting member, the second fitting member comprises a first unlocking part and a second unlocking part, and in an initial situation, the first action member is positioned corresponding to the first unlocking part;
- the first action member acts on the first unlocking part and the second action member acts on the first fitting member, neither of which is capable of driving the movable member to be completely retracted into the first lock body;
- the second action member acts on the first fitting member to drive the movable member to act for transforming the first action member from corresponding to the first unlocking part to corresponding to the second unlocking part, the first action member acts on the second unlocking part to drive the movable member to act to completely retract into the first lock body, and thus the safety lock device is transformed into an unlocked state.
