The sub-tongue piece 8 and the main tongue piece 9 are each provided with two groups and are rotatably connected to the lock body 1. A double-hook spring 10 is connected between the sub-tongue piece 8 and the main tongue piece 9. One side of the main tongue piece 9 is rotatably connected to a gear sub-piece 11. One side of the gear sub-piece 11 is rotatably connected to a gear main piece 12. The gear sub-piece 11 is meshed with the gear main piece 12. Through the meshing between the gear sub-piece 11 and the gear main piece 12, when one of the gear sub-piece 11 or the gear main piece 12 rotates, the other can be driven to rotate.

[0031] A gear paddle 13 is fixed to one side of the lock plate 7 by screws, and the gear paddle 13 is located between the gear sub-plate 11 and the gear mother plate 12. When the gear paddle 13 is tilted, it can drive the gear sub-plate 11 or the gear mother plate 12 to rotate. The bottom surface of the buckle plate 4 is provided with a paddle groove for cooperating with the installation of the gear paddle 13. The center position is provided with a vertical threaded hole, and a screw is used to fix the shaft pin 5.

[0032] The threaded member is a mounting screw 14, two of which are provided and are both rotatably connected to the surface of the lock body 1, and the fastener is a hook 15, which is provided on the surface of the lock body 1. The hook 15 pre-fixes the lock body 1 and the door and window aluminum material 21 by means of wall-facing fastening, and is screwed and fixed to the door and window aluminum material 21 by the mounting screw 14 provided at the convex edge of the side of the lock body 1, thereby realizing secondary fixation of the lock body 1 and greatly enhancing the stability of the lock body 1 after fixation.

[0033] A first inner cavity decorative cover 16 is screwed into one end of the lock body 1 by screws, a beveled nut 17 is provided on one side of the first inner cavity decorative cover 16 and a slider clamp 18 is provided on one side of the beveled nut 17, a spring is provided between the beveled nut 17 and the slider clamp 18, a second inner cavity decorative cover 19 is screwed into the other end of the lock body 1 by screws, a fixing clamp 20 is provided on one side of the second inner cavity decorative cover 19, and the first inner cavity decorative cover 16 and the second inner cavity decorative cover 19 are respectively provided on both sides of the lock body 1, which can increase the aesthetics of the lock body 1 and prevent dust, dirt and other impurities from entering the interior of the lock body 1, thereby extending the service life of the lock body 1.

[0034] The door and window lock with a dual installation and fixing mechanism pre-fixes the lock body 1 and the door and window aluminum material 21 by means of a hook 15 provided on the side of the lock body 1 to buckle the lock body 1 to the wall, and screws and fixes the lock body 1 to the door and window aluminum material 21 by means of a mounting screw 14 provided on the convex edge of the side of the lock body 1, thereby realizing secondary fixation of the lock body 1, greatly enhancing the stability of the lock body 1 after being fixed and making the installation relatively simple.

[0035] When the lock is in a locked state, under the force of the double hook spring 10, the tongue pieces (sub-tongue pieces 8 and main-tongue pieces 9) and the gear pieces (gear sub-pieces 11 and gear main-pieces 12) and the gear paddles 13 are subjected to corresponding balancing mutual forces, and the clasp plate 4 is in a leveling state accordingly. When the clasp plate 4 is tilted toward one end (such as Figure 3 As shown in the figure, the gear paddle 13 is synchronously acted upon by force, which causes the gear mother plate 12 to rotate and move accordingly, thereby driving the mother tongue plate 9 to rotate through the force. At the same time, under the interaction force, the child tongue plate 8 also rotates accordingly, thereby achieving unlocking. At this time, the double hook spring 10 is pulled by the mother tongue plate 9 and the child tongue plate 8, and the double hook spring 10 is in a stretched state (as shown in the figure). Figure 4 As shown), when the lock plate 4 needs to be closed without force, the tongue piece (sub-tongue piece 8 and main tongue piece 9) and the gear piece (gear sub-piece 11 and gear main piece 12) and the gear paddle 13 return to the natural state along the motion trajectory relative to each other under the pulling force of the double hook spring 10, thereby achieving locking.

[0036] The lock hook 23 is fixed on the hook groove of the aluminum material 21 through the mounting block 22 (such as Figure 6 As shown in the figure, when the sliding door is to be locked, the arrow end of the lock hook 23 vertically collides with the locking opening of the lock body 1, causing the tongue piece (sub-tongue piece 8 and main tongue piece 9) to rotate and the locking opening to expand until the arrow portion of the lock hook 23 passes through the opening between the sub-tongue piece 8 and the main tongue piece 9. Under the pulling force of the double hook spring 10, the lock tongue piece is still tightly attached to both sides of the arrow tail (as shown in the figure). Figure 8As shown), if the lock hook 23 is to be reset and moved out, it is locked. If it is to be unlocked, the buckle plate 4 is tilted to make the gear paddle 13 synchronously acted upon by force, and the force causes the gear mother plate 12 to rotate and move accordingly, thereby driving the mother tongue plate 9 to rotate through the force. At the same time, under the interaction force, the child tongue plate 8 also rotates accordingly to widen the locking mouth, thereby achieving unlocking, and the lock hook 23 can be moved out without obstruction (as shown in FIG. Fig. 9 As shown), the unlocking function is achieved.
