The reference numerals in the drawings specifically are:

the lock comprises a lock body 1, an accessory 2, a lock cylinder 3, a plug-in fastener 4, a plug pin channel 5, a limit groove 6, a limit rope 7, a storage groove 21, a lock tongue 31, a through hole 40, a clamping tongue 41, a return spring 46, a plug pin 51 and an annular groove 52.

The specific embodiment is as follows:

the utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1 to 3, the utility model is a portable child safety lock, which comprises a lock body 1 and an accessory 2, wherein a lock cylinder 3 and a plug-in card 4 are arranged in the lock body 1, the end part of the lock cylinder 3 is connected with a lock tongue 31, the lock tongue 31 is linked with the plug-in card 4, a bolt channel 5 is also arranged in the lock body 1, the accessory 2 is connected with a bolt 51 through a limiting rope 7, the bolt 51 is matched with the bolt channel 5, and an annular groove 52 is arranged at the end part of the bolt 51 and is matched with the plug-in card 4. The lock cylinder 3 drives the lock tongue 31 to rotate in the switching process, and then the linkage card inserting piece 4 realizes the sideslip, so that the end part of the card inserting piece 4 enters and exits the bolt passage 5, and the locking or releasing of the bolt 51 is completed.

Specifically, the card inserting piece 4 is provided with a through hole 40, the lock tongue 31 is positioned in the through hole 40, the area of the through hole 40 is larger than that of the lock tongue 31, and the lock tongue 31 is an eccentric body. When locking, one side of the card inserting piece 4 is tightly attached to the side wall of the through hole 40, and when the lock tongue 31 rotates, the eccentric structure drives the card inserting piece 4 to move to one side, so that the card inserting piece 4 is withdrawn from the bolt channel 5.

One side of the bolt channel 5 is provided with a limit groove 6, and the card inserting piece 4 is arranged above the limit groove 6, namely, the limit groove 6 and the inner wall of the lock body 1 form a channel for the card inserting piece 4 to slide.

A reset spring 46 is arranged between the lower end of the card inserting piece 4 and the limit groove 6, a clamping tongue 41 is arranged on one side of the card inserting piece 4 corresponding to the bolt channel 5, the clamping tongue 41 is provided with an inclined plane, and the clamping tongue 41 is matched with the annular groove 52. The end of the bolt 51 is provided with a chamfer, when the bolt 51 is inserted, the end of the bolt is propped against the inclined surface of the clamping tongue 41, so that the plug-in card 4 can retract to the side surface and withdraw from the bolt channel 5 until the end surface of the bolt 51 is propped against the tail end of the bolt channel 5, at the moment, the annular groove 52 of the bolt 51 forms a notch at the parallel position of the clamping tongue 41, and then the clamping tongue 41 reenters the bolt channel 5 under the action of the reset spring 46 and is inserted into the annular groove 52, thereby completing the clamping and fixing of the bolt 51.

The lock core 3 can adopt the existing simple lock core or directly adopts a rotatable rotating shaft, and the purpose is to twist the lock core by inserting a key as a handle, so that the lock core 3 does not need a complex lock body structure, namely, the lock tongue 31 is replaced by a gear, the inner wall of the through hole 40 of the card inserting piece 4 forms a tooth row, the lock core 3 can be rotated to drive the card inserting piece 4 to transversely move, the lock tongue 31 can be driven to rotate in the process of pushing the card inserting piece 4 by the bolt 51, and then the reset of the card inserting piece 4 is completed by the reset spring 46.

The limit rope 7 is preferably a steel wire rope, and has enough tensile property to ensure that the structure is stable after locking. The accessory 2 is provided with a storage groove 21, as shown in fig. 4, the storage groove 21 is connected with the accessory 2 through the conventional torsion spring (not shown in the figure), one end of the limiting rope 7 is connected with the storage groove 21, the limiting rope 7 is pulled out during locking, the torsion spring is in a force storage state, after locking, movable parts such as doors and windows and the like can be closed with fixed parts, if the movable parts of the doors and the windows adhered by the accessory are opened, the opening process of the movable parts can pull the limiting rope 7 to extend outwards continuously and is more and more forceful until the limiting rope 7 is pulled out to a limiting position, and the service life of the limiting rope 7 is prevented from being influenced by excessive force; on the contrary, after the movable part of the door and window is loosened, the torsion spring is reset, so that the limiting rope 7 can also be driven to pull the movable part with a certain weight, and the movable part is slowly closed towards the direction of the fixed part.

It should be understood that the technical scope of the present utility model is not limited to the description, but may be modified or changed according to the above description by those skilled in the art, and all such modifications and changes should fall within the scope of the appended claims.
