When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] Please refer to 1 to Figure 4 A push-button window lock provided by an embodiment of the utility model comprises a lock body 10 and a lock hook 20. The lock body 10 comprises a shell 11, a connecting plate 12 arranged at the lower end of the shell 11, a cover plate 15 connected to the connecting plate 12, two toggle members 13 rotatably connected to the cover plate 15, a tension spring 14 connecting the two toggle members 13, and a switch button 18 arranged on one side of the shell 11. The switch button 18 is transmission-connected to the first ends of the two toggle members 13 to drive the second ends of the two toggle members 13 away from each other to clamp the lock hook 20 to achieve locking; a long groove 151 is respectively provided on both sides of the cover plate 15, and the long groove 151 is vertically arranged. Each long groove 151 is provided with a fastener 30, which is used to adjust the length of the cover plate 15 extending out of the shell 11 to adapt to the thickness of the profile.

[0028] Furthermore, a slope is symmetrically arranged on the inner side of the switch button 18, the slope is tilted toward the middle, and the slope contacts the first end of the toggle member 13. When the switch button 18 is pressed, the slope drives the second end of the toggle member 13 to rotate around the pivot point, so that the second ends of the two toggle members 13 move away from each other.

[0029] The above-mentioned push-button window lock, because the cover plate 15 is connected to the connecting plate 12 through the long groove 151, the cover plate 15 can be pulled up or down by unscrewing the fastener 30, and then the position of the cover plate 15 can be adjusted according to the size of the installed door and window, thereby achieving the adaptation of various products and improving the application range of the window lock.

[0030] In one embodiment of the utility model, it also includes a knob 16, which is arranged on the other side of the shell 11. The knob 16 is provided with a blocking portion. When the knob 16 is rotated until the blocking portion abuts against the inner side of the switch button 18, the switch button 18 is in a locked state. Furthermore, the knob 16 is provided with a avoiding portion. When the switch button 18 is in an active state, the avoiding portion is opposite to the inner side of the switch button 18.

[0031] In one embodiment of the present invention, a key connected to the knob 16 is further included, for driving the knob 16 to rotate to lock or unlock the switch button 18 .

[0032] In an embodiment of the present invention, a locking hole 152 is provided at a position of the cover plate 15 corresponding to the locking hook 20 , and the locking hook 20 passes through the locking hole 152 and is clamped between the two toggle members 13 .

[0033] In an embodiment of the present invention, the toggle member 13 is rotatably connected to the housing 11 via a rotating shaft 40 .

[0034] In one embodiment of the present invention, the fastener 30 is any one of a screw or a bolt.

[0035] In one embodiment of the present invention, at least two positioning points 153 are spaced apart on the upper side of the cover plate 15 , and the positioning points 153 are arranged in pairs in the same row, so that the cover plate 15 can be quickly aligned after adjusting its position, thereby preventing the cover plate 15 from tilting.

[0036] In an embodiment of the present invention, a buckle 50 is respectively provided on both sides of the shell 11 to fix the shell 11 to the profile of the door and window by snapping.

[0037] In one embodiment of the utility model, the lock hook 20 includes a connecting portion 21 and a hook portion 22 connected to the connecting portion 21. Specifically, the opening and closing distance of the two toggle members 13 is greater than the width of the hook portion 22, so that the lock hook 20 can be moved out of the lock body 10, and the tension spring 14 causes the two toggle members 13 to automatically reset.

[0038] In one embodiment of the utility model, a limiting tongue 154 is provided in the middle of the cover plate 15, and the limiting tongue 154 is arranged between the two toggle members 13, so that there is a gap between the two toggle members 13 with the same width as the limiting tongue 154, thereby facilitating the insertion of the lock hook 20 between the two toggle members 13.

[0039] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
