Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

The first embodiment is as follows:

as shown in fig. 1 to 7, a door and window lock provided in an embodiment of the present invention may be used as a window and window lock, and includes a lock body 10 and a key type handle 20 connected to the lock body 10 and separable from the lock body 10 when rotating to a set angle, where the lock body 10 includes a housing 11, an unlocking member, and a driving member 12 connected to the key type handle 20 and driven by the key type handle 20, the driving member 12 is rotatably connected to the housing 11, a transmission structure (not shown in the figure) is disposed between the driving member 12 and the unlocking member, and when in use, the key type handle 20 may be abutted to the driving member 12, the driving member 12 is operated by operating the key type handle 20, and the unlocking member is operated by the transmission structure to unlock the window and window lock. When the key handle 20 is rotated to a predetermined angle, for example, the angle corresponding to the key handle 20 when the door and window lock is in the locked state, the key handle 20 can be disengaged from the driving member 12, and at other angles, the key handle 20 cannot be disengaged from the driving member 12. That is, the keyed handle 20 may be docked with the lock body 10 and used as an operating handle, or may be separated from the lock body 10 and used as a key for the lock. The key type handle 20 can be connected with the lockset into an integrated assembly structure, the key type handle 20 can be used as a key and is one of components of the lockset, the key (the key type handle 20) is not easy to lose, and the user experience is good.

Specifically, the transmission structure may include a gear and a rack, the gear is connected to the driving member 12, the rack is connected to the unlocking member, and the rack is engaged with the gear, so that when the driving member 12 rotates, the gear rotates and drives the rack to slide, and then the unlocking member (for example, a shifting fork or a locking piece) slides to realize unlocking or locking. Of course, the transmission structure can also adopt a gear set, a transmission rod and other structures.

Specifically, an open slot 201 is arranged at the front end of the key type handle 20, the driving member 12 is provided with a connecting portion 121 matched with the open slot 201, and the open slot 201 is sleeved on the connecting portion 121; the open card slot 201 may be U-shaped to facilitate use by a user. Or, the front end of the key type handle 20 is provided with a connecting part 121, the driving part 12 is provided with an open slot, and the connecting part 121 is inserted into the open slot.

Specifically, the cross section of the connection portion 121 may be non-circular, may be rectangular, or the like.

Specifically, the front end of the key type handle 20 is provided with a hook structure 23, when the key type handle 20 is opened to a set range (for example, a maximum openable angle) relative to the lock body 10, the hook structure 23 can be hooked to the housing 11, so that the tensile strength of the handle can be improved, and the service life of the handle can be prolonged.

Specifically, the hook structure 23 may be disposed below the open slot 201.

In specific applications, the key type handle 20 is coupled to the lock body 10 in a manner of connecting a shaft with a hole, or in a manner of connecting a shaft with a spring plate, or in an auxiliary connection manner through a magnetic attraction structure, that is, the key type handle 20 and the driving member 12 can be in an auxiliary fit connection through a magnetic attraction device, or in an elastic buckle manner.

Specifically, the housing 11 is provided with a handle slot 111 for accommodating the key handle 20, so that the key handle 20 cannot be disengaged from the driving member 12 within a certain angle range. Specifically, the front end of the key-type handle 20 is further provided with a protruding insertion protrusion 22, the insertion protrusion 22 can be inserted into the end side of the handle groove 111, and the key-type handle 20 can be separated from the driving member 12 only by pulling up a set angle by matching the structure of the key-type handle 20 and the handle groove 111.

In the concrete application, the opening part of opening draw-in groove 201 can be provided with direction inclined plane or direction cambered surface to it is more smooth and easy when making the butt joint, user experience is better.
