The present invention provides a buckle lock includes a lock member and a buckle base which are able to be inserted and locked to each other. The buckle base includes a lock portion and a release button, and the lock portion includes at least one locking mechanism. It is characterized in that when the locking mechanism is in a locked state, the lock member can still be inserted into the buckle base and the lock connection is completed immediately after completing the locking action.
1. A buckle lock, comprising:
a lock member having an insert portion;
a buckle base including a lock housing that has a first cover and a second cover, wherein the second cover has an end that defines a slot opening and that is coupled fixedly to the first cover and the buckle base is configured with a slot for receiving the insert portion through the slot opening;
a lock portion having at least one locking mechanism configured on the buckle base, wherein the locking mechanism is changeable between a locked state and an unlocked state; and
a release button configured on the buckle base, pushed by a first elastic member to maintain in an ejected position, and pressable to move to a push-down position;
wherein the insert portion of the lock member is able to be inserted into the slot of the buckle base to form a connection, when the locking mechanism is in the unlocked state, the release button is pressed to the push-down position to release the connection between the lock member and the buckle base, and when the locking mechanism is in the locked state, the insert portion can still be inserted into the slot and be locked immediately after completing the insertion action;
a movable latch having a linkage with the release button, pushed by a second elastic member, normally maintained at a lock position for limiting the insert portion, and able to be moved to an unlock position when the insert portion is released; and
a positioning block located in the slot, having a linkage with the movable latch, pushed by a third elastic member, kept in a push-out position normally, and movable to a retracted position by connecting the insert portion when the insert portion is inserted in the slot.
2. The buckle lock of claim 1 , wherein a hole for limiting the movable latch is configured with the insert portion.
3. The buckle lock of claim 1 , wherein when the positioning block is in the push-out position, the movable latch is kept in the unlock position against the positioning block so that when the positioning block is in the retracted position, the movable latch is pushed and moved to the lock position by the second elastic member.
4. The buckle lock of claim 1 , wherein the locking mechanism is a combination lock mechanism, when the locking mechanism is in the unlocked state, the release button is pressed to move to the push-down position and the movable latch can be moved to the unlock position in conjunction with the release button.
5. The buckle lock of claim 4 , wherein the combination lock mechanism includes a movable plate which has abutting relationship with the release button, when the combination lock mechanism is in the locked state, the movable plate is located at a first position where the release button is not able to be pressed and moved, and when the combination lock mechanism is in an unlocked state, the movable plate moves to a second position that allows the release button to be pressed and moved.
6. The buckle lock of claim 1 , wherein the locking mechanism is a key lock mechanism, the key lock mechanism includes a cam portion that has a linkage with the movable latch, and when the key lock mechanism changes from the locked state to the unlocked state, the cam portion will move accordingly and the movable latch will moved from the lock position to the unlock position.
7. The buckle lock of claim 1 , further comprising a connecting piece, wherein a first end of the connecting piece is connected to the lock member, and a second end of the connecting piece is connected to the buckle base.
8. The buckle lock of claim 7 , wherein the connecting piece is selected from a bar, a steel cable or a webbing.
9. A buckle lock comprising:
a lock member having an insert portion;
a buckle base including a lock housing that has a first cover and a second cover, wherein the second cover has an end that defines a slot opening and that is coupled fixedly to the first cover and the buckle base is configured with a slot for receiving the insert portion through the slot opening;
a lock portion having at least one locking mechanism configured on the buckle base, wherein the locking mechanism is changeable between a locked state and an unlocked state; and
a release button configured on the buckle base, pushed by a first elastic member to maintain in an ejected position, and pressable to move to a push-down position, wherein the insert portion of the lock member is able to be inserted into the slot of the buckle base to form a connection, when the locking mechanism is in the unlocked state, the release button is pressed to the push-down position to release the connection between the lock member and the buckle base, and when the locking mechanism is in the locked state, the insert portion can still be inserted into the slot and be locked immediately after completing the insertion action; and
a movable latch having a linkage with the release button, pushed by a second elastic member, normally maintained at a lock position for limiting the insert portion, and able to be moved to an unlock position when the insert portion is released, wherein the locking mechanism is a key lock mechanism, the key lock mechanism includes a cam portion that has a linkage with the movable latch, and when the key lock mechanism changes from the locked state to the unlocked state, the cam portion moves accordingly and the movable latch moves from the lock position to the unlock position.
