It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The following provides a term explanation of the present application.

The hook lock is a door and window hardware fitting, and generally comprises a lock shell and a transmission piece, wherein the transmission piece is arranged in the lock shell and can move back and forth in the lock shell to drive the position of a lock hook to be sent and changed, so that the door and window can be opened and locked.

Hereinafter, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 to 5, the latch 1 may include a bar-shaped latch case 11, an upper plug 12, a lower plug 13, a transmission member 14, a latch hook fixing seat 15, and a latch hook 16. The hook lock 1 and the opposite-side mechanism to be locked 2 are locked, so that the door and window can be unlocked and locked.

The back of the bar-shaped lock case 11 is provided with a mounting groove 111. The front surface of the strip-shaped lock shell 11 faces the user, and is provided with a waist-shaped hole.

The upper plug 12 is located at the upper end of the installation groove 111, and partially protrudes out of the installation groove 111.

The lower plug 13 is located at the lower end of the mounting groove 111, and partially protrudes out of the mounting groove 111.

The transmission member 14 is slidably disposed in the mounting groove 111 and is movable between the upper plug 12 and the lower plug 13. The transmission member 14 is provided with a pressing portion which is caught in the waist-shaped hole of the bar-shaped lock case 11. The user presses the pressing portion so that the pressing portion is disengaged from the edge of the waist-shaped hole and continues to press down so that the transmission member 14 slides.

The latch hook fixing seat 15 is slidably located on the mounting groove 111 and is in snap connection with the transmission member 14. The latch hook fixing seat 15 is provided with a boss 151, and the boss 151 is provided with a fixing groove and a plurality of threaded holes. The fixing groove penetrates through two sides of the boss 151, and the fixing groove is rectangular cube-shaped. The screw holes penetrate from the outer side wall of the boss 151 to the fixing groove.

The latch hook 16 includes a bar-shaped fixing member 161 and a hook 162 connected to the bar-shaped fixing member 161.

The axial direction of each threaded hole in the plurality of threaded holes is inclined to the middle part of the fixing groove; the bar-shaped fixing member 161 is at least partially positioned in the fixing groove and is fixed by a plurality of screws 152 corresponding to the plurality of screw holes.

In this embodiment, the user may apply force to slide the transmission member 14 downward. The transmission member 14 drives the latch hook fixing seat 15 to slide downward, and the latch hook 16 is fixed on the latch hook fixing seat 15, so that the latch hook 16 also moves downward. After the latch hook 16 moves downwards, the latch hook can just catch the mechanism 2 to be locked, so that locking of doors and windows is realized.

It should be noted that the latch hook 16 may also be upward. Under the condition that the latch hook 16 faces upwards, the latch hook 16 can be just separated from the mechanism 2 to be locked after moving downwards, so that the door and window can be converted from a locking state to an opening state.

In this embodiment, since the axial direction of each threaded hole is inclined toward the middle of the fixing groove, each screw is inclined (laterally inward) against the edge of the bar-shaped fixing member 161, and the installation is convenient and not limited. In addition, the plurality of screw holes penetrate from the outer side wall of the boss 151 to the fixing groove, and at the same time, since each screw 152 is inclined (laterally inward), the bar-shaped fixing member 161 receives an acting force and a reverse acting force, so that the bar-shaped fixing member is firm and not loose, and is not easy to fall off, and the conventional point-to-point acting force is changed.

In an alternative embodiment, the outer side wall of the boss 151 is in a rectangular cube shape corresponding to the fixing groove, and a chamfer is provided at a corner of the outer side wall of the boss 151. The chamfer provides a port at one end of the threaded bore. In this embodiment, the screw holes are formed from the 4 chamfer surfaces on the side of the boss 151, so that the screw 152 can be inclined against the bar-shaped fixing member 161, and the screw 152 can be conveniently mounted.

In an alternative embodiment, the axes of the threaded bores are perpendicular to the corresponding chamfer faces to further facilitate installation of the screws 152.

Alternatively, both sides of the strip-shaped fixing member 161 are provided with engagement surfaces formed by alternating peak lines and concave lines; wherein the directions of the peak line and the concave line are perpendicular to the opening direction of the fixed groove. This arrangement can be increased in firmness, less prone to loosening.

In an alternative embodiment, the hook lock 1 further comprises: a fixed pin 17 and a spring 18.

The fixing pin 17 is positioned at the upper end of the bar-shaped lock case 11 and is bridged at both sides of the installation groove 111.

A spring 18 is abutted between the underside of the upper plug 12 and the fixing pin 17;

wherein, under the action of external force, the upper plug 12 compresses the spring 18 and slides towards the direction of the fixed pin 17; in the case where the external force is lost, the resilience of the spring 18 causes the upper plug 12 to slide back.

In the above embodiment, the latch 1 can be easily installed in the corresponding mating structure of the door and window without the need for disassembly and installation.

In some embodiments, the latch 1 further comprises a ball 19. Two accommodating parts are arranged at one end of the transmission part 14, which is close to the lower plug 13, and the two accommodating parts are distributed at two sides of the transmission part 14. The two receiving portions are for receiving the two balls 19. The two balls 19 are restrained by guide rails inwardly of the upper edge of the mounting groove 111 so as not to be separated from the receiving portion. The balls 19 can assist in sliding during sliding of the transmission 14.
