[0024] There are two toggle shafts 20 , each of which includes a shaft portion 21 and a connecting portion 22 connected to the lower side of the shaft portion 21 . The shaft portion 21 is provided with a polygonal hole 23 for connecting to a door or window handle, and the connecting portion 22 is used to connect to the toggle rod 30 .

[0025] The partition mounting block 10 is provided with a toggle shaft mounting groove 11 and a toggle plate mounting groove 12. A partition 13 is provided on the side wall of the toggle shaft mounting groove 11, and two toggle shafts 20 are respectively installed on the front and rear sides of the toggle shaft mounting groove 11 and separated by the partition 13. The toggle shaft 20 can rotate in the toggle shaft mounting groove 11 with the rotating shaft portion 21 as the axis, and the toggle shaft mounting groove 11 can limit the maximum rotation stroke of the connecting portion 22 of the toggle shaft 20, playing a role of limiting. The toggle plate 40 is installed on the toggle plate mounting groove 12 so as to be movable horizontally left and right, and the toggle plate mounting groove 12 can limit the maximum movement stroke of the toggle plate 40, playing a role of limiting.

[0026] The front and rear ends of the toggle lever 30 are respectively connected to the connecting parts 22 of the toggle shafts 20 at the front and rear sides, and rotate synchronously with the toggle shafts 20. The toggle plate 40 is provided with a toggle groove 41, and the toggle lever 30 is clamped in the toggle groove 41. When the toggle shaft 20 rotates, it can drive the toggle plate 40 to move horizontally left and right. The transmission plate 50 is connected to the toggle plate 40 and can move horizontally left and right with the toggle plate 40.

[0027] Two cover plates 60 are provided, and the two cover plates 60 are respectively fixed on the front and rear sides of the partition mounting block 10 by rivets 61. In addition, the toggle plate 40 is provided with a rivet limiting groove 42. The rivet 61 is penetrated through the toggle plate mounting groove 12 and is located in the rivet limiting groove 42 to limit the left and right lateral movement of the toggle plate 40. The cover plate 60 is provided with an arc limiting groove 62, and the front and rear ends of the toggle rod 30 are respectively located in the arc limiting grooves 62 of the front and rear cover plates 60. Through this structure, the rotation of the toggle rod 30 can be limited.

[0028] The cylindrical nut 70 is arranged through the partition mounting block 10 and the cover plates 60 at the front and rear sides, and a nut pad 80 is also arranged on one side of the cover plate 60 at the position of the cylindrical nut 70. When the door and window lock box is installed on the door and window, the door and window lock box can be installed by the cooperation of the screw and the cylindrical nut 70, and the arrangement of the nut pad 80 can improve the installation tightness.

[0029] The transmission plate pad 90 is made of plastic material, connected to the lower side of the transmission plate 50 so that the two are integrated, and the transmission plate pad 90 is arranged on the base 100 so as to be movable horizontally left and right. By setting the transmission plate pad 90, the smoothness of movement of the transmission plate 50 can be improved, and the noise generated when the transmission plate 50 moves can be reduced. The transmission plate 50 and the transmission plate pad 90 are provided with strip-shaped limiting grooves 51 and 91 at the same position, and the one-way base 100 is connected with a limiting stud 101, which is located in the strip-shaped limiting grooves 51 and 91. Through this structure, the left and right lateral movement of the transmission plate 50 and the transmission plate pad 90 can be limited.

[0030] The fastening gasket 110 is sleeved on the outer bottom of the partition mounting block 10 and is located on the upper side of the transmission plate 50, and the limiting stud 101 sequentially passes through the strip limiting grooves 51, 91 and the fastening gasket 110. The fastening gasket 110 is used to improve the installation fastness of the door and window lock box when it is installed on the door and window.

[0031] The partition mounting block 10 is fixed on the base 100 by connecting screws 120 and screw bushings 130 .

[0032] When in use, the door and window handle is installed on the polygonal hole 23 of the toggle shaft 20. When the door and window handle is turned, the toggle shaft 20 rotates, and through the cooperation of the toggle rod 30 and the toggle plate 40, the transmission plate 50 is driven to move horizontally left and right, thereby realizing the opening and locking of the door and window lock box. When the door and window handle is turned too hard, the toggle shafts 20 on the front and rear sides can disperse the impact force to the partition mounting block 10, so that the toggle shaft 20 is not easily deformed or cracked by impact, and has the characteristics of strong impact resistance, so as to ensure the normal service life of the door and window lock box. In addition, the various limit structures mentioned above can also be used to buffer the impact force, so as to further improve the impact resistance of the toggle shaft 20.

[0033] The above structure can be applied not only to one-way door and window lock boxes, but also to two-way door and window lock boxes.

[0034] The above embodiments are only used to illustrate the present invention and are not intended to limit the present invention in any form. Any person with ordinary knowledge in the technical field may make partial changes or modifications to the technical contents disclosed in the present invention without departing from the scope of the technical features of the present invention, and the equivalent embodiments without departing from the technical features of the present invention are still within the scope of the technical features of the present invention.
