Technical Field

The present invention relates to the technical field of hardware, and in particular to a lock.

Background technique

Locks are devices used to lock and open doors and windows.

At present, the commonly used locks for doors and windows are provided with a lock box, a lock body, a lock tongue and a lock switch. The lock tongue is controlled to extend and retract in the lock body by operating the lock switch. When the lock switch is adjusted to the unlocking mode, the lock tongue is in the lock body and the door leaf can be moved at will. When the lock switch is adjusted to the locking mode, the lock tongue is outside the lock body and can cooperate with the lock box to lock.

However, if there is an accidental touch, causing the lock switch to be adjusted to the locked mode when the door or window is open, that is, the lock tongue extends out of the lock body when the door or window is open, it is easy for the lock tongue to hook or scratch a person or object, creating a safety hazard.

Summary of the invention

To solve at least one of the problems existing in the above-mentioned prior art, according to one aspect of the present invention, a lock is provided, comprising: a lock body and a lock box arranged opposite to each other; a lock tongue, which is arranged on the lock body, and when the lock body enters the lock box, the lock body is used to control the lock tongue to lock with the lock box; a suction mechanism, when the lock body is close to the lock box, the suction mechanism is used to make the lock tongue extend out of the lock body and enter the lock box; when the lock body is away from the lock box, the suction mechanism is used to store the lock tongue in the lock body, and the lock tongue is restricted to an unlocked state.

In this way, the extension and retraction of the lock tongue in the lock body is controlled by setting up a suction mechanism, thereby controlling the locking of the lock body and the lock box. Specifically, when the door and window are closed, the suction mechanism controls the lock tongue to enter the lock box, and when the door and window are opened, the suction mechanism controls the lock tongue to be stored in the lock body, and the lock tongue is restricted to an unlocked state. Therefore, the lock tongue will not be accidentally touched and extended out of the lock body, thereby causing the lock tongue to hook or scratch a person or object, creating a safety hazard.

In some embodiments, the attraction mechanism includes a first magnetic member and a second magnetic member, and the first magnetic member and the second magnetic member are respectively arranged in the lock tongue and the lock box. When the lock body is close to the lock box, a first attractive force is generated between the first magnetic member and the second magnetic member.

In some embodiments, the attraction mechanism also includes a reset member connected to the lock tongue, which provides a second force to the lock tongue so that the lock tongue is retracted into the lock body. When the lock body is away from the lock box, the second force is greater than the first force. When the lock body is close to the lock box, the first force is greater than the second force.

In some embodiments, the lock box includes: a lock slot, which is arranged in the lock box; a bayonet, which is arranged in the lock box and connected to the lock slot, and is used to accommodate a lock tongue entering the lock slot; the lock tongue has a hook-shaped locking portion, and after entering the lock slot, there is a gap between the inner surface opposite to the lock slot, and the locking portion is used to move along the bayonet to complete the locking or unlocking action.

In some embodiments, a limiting groove is provided on the surface of the lock body, and when the lock body is away from the lock box, the limiting groove is used to accommodate the locking part.

In some embodiments, the lock body is provided with a accommodating cavity, in which are provided: a connecting piece for configuring a lock tongue, on which one end of a reset piece away from the lock tongue is fixed; and a first slide groove provided in the accommodating cavity for moving the connecting piece along the first slide groove.

In some embodiments, the reset element is a spring, and when the spring is in a natural state, the lock tongue is received in the lock body.

In some embodiments, a lock switch is provided on the lock body, and the lock switch is connected to a side of the connecting member away from the lock tongue, and the lock switch is used to drive the connecting member and thus drive the lock tongue to move along the first sliding groove.

In some embodiments, the connecting member is further provided with a second sliding groove for allowing the locking tongue to move along the second sliding groove.

In some embodiments, a buffer is provided on one end of the connecting member close to the resetting member to mitigate the impact generated when the locking tongue is resetting.

The technical solution of the embodiment of the present invention has at least the following advantages and beneficial effects:

1) The present invention is provided with a suction mechanism to control the extension and retraction of the lock tongue in the lock body. Specifically, when the door and window are closed, the suction mechanism controls the lock tongue to enter the lock box, and when the door and window are opened, the suction mechanism controls the lock tongue to be stored in the lock body, and the locking portion of the lock tongue is fixedly stored in the limiting groove, so that the lock switch cannot move the lock tongue through the connecting piece, so that the lock tongue is limited to the unlocked state when the door and window are opened, so that there will be no accidental touch causing the lock tongue to extend out of the lock body to cause a safety hazard.

2) When closing doors and windows, the first force of attraction between the first magnetic part and the second magnetic part on the lock tongue is greater than the second force generated by the reset part. Therefore, compared with existing locks, the present invention saves more effort in closing doors and windows and improves the comfort of users.

3) The lock tongue of the present invention is hook-shaped. After the lock tongue enters the lock box, the lock can be locked or unlocked by moving the lock switch.
