For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] As shown in the figure, the present invention includes a transmission square bar 1 and a mounting seat 2. The transmission square bar 1 axially passes through the mounting seat 2. The transmission square bar 1 and the mounting seat 2 are relatively rotated. The transmission square bar 1 is positioned by positioning members 3 on both axial sides of the mounting seat 2. The positioning members 3 can be a retaining spring, or a positioning ring radially extended and formed as an integral part on the transmission square bar 1. When the transmission square bar 1 rotates relative to the mounting seat 2, it drives the locking mechanism (omitted in the figure) to lock the window sash. A radially extending isolation positioning ring 4 is provided in the middle of the mounting seat 2, and the isolation positioning ring 4 separates the mounting seat 2 into an inner mounting seat 2A and an outer mounting seat 2B. The outer mounting seat 2B is a first boss 5 extending axially outward along the isolation positioning ring 4, and the inner mounting seat 2A is a second boss 6 extending axially inward along the isolation positioning ring 4. The radial distance of the second boss 6 is smaller than the diameter of the isolation positioning ring 4. A through hole 7 is axially opened around the transmission square bar 1 in the mounting seat 2, and a positioning groove 8 is formed at the end of the first boss 5 through the through hole 7. A locking screw 9 is inserted in the through hole 7, and the larger diameter cap end of the locking screw 9 is restricted in the positioning groove 8. The through hole 7 is radially expanded into a slide groove 11 on the second boss 6, and a locking pressure plate 10 is axially embedded in the slide groove 11. The locking pressure plate 10 is provided with a screw hole 10a which is threadedly connected with the locking screw 9, and the bottom of the locking pressure plate 10 is matched with the bottom surface of the slide groove 11 through an inclined surface 12. Matching guide ribs 18 and guide grooves 19 are respectively provided on the side walls of the locking plate 10 and the slide groove 11, and the guide ribs 18 and the guide grooves 19 have the same inclination as the inclined surface 12. When the locking screw 9 rotates, the locking plate 10 rises through the inclined surface 12 and the cooperation of the guide ribs 18 and the guide grooves 19, and the mounting wall of the clamping profile is clamped. In the design of the first embodiment, the diameter of the through hole 7 is larger than the diameter of the locking screw 9, and the locking screw 9 is swingably set in the through hole 7. When the locking screw 9 rotates, the locking plate 10 rises through the cooperation of the inclined surface 12 and the guide ribs 18 and the guide grooves 19, and the locking screw 9 swings upward in the through hole 7. In the design of the second embodiment, the through hole 7 and the screw hole 10a on the locking plate 10 have the same inclination design as the inclined surface 12, and the locking screw 9 passes through the through hole 7 and is threadedly connected to the locking plate 10. When the locking screw 9 rotates, the locking pressure plate 10 rises through the inclined surface 12, the inclined screw hole 10a and the through hole 7, as well as the guide rib 18 and the guide groove 19. A pressure plate 13 is concentrically arranged on the outside of the outer mounting seat 2B. The pressure plate 13 is provided with a slot 14 that matches the locking screw 9. The diameter of the slot 14 is smaller than the cap end diameter of the locking screw 9. The pressure plate 13 is rotated by the transmission square bar 1. Blind holes 15 are arranged on the mounting seat 2 at the same circumferential interval as the through hole 7. A spring 16 and a steel ball 17 are installed in the blind hole 15. The steel ball 17 matches the slot 14 at the same time. The positioning member 3 on the outside of the transmission square bar 1 adopts a square sleeve 3a. The square sleeve 3a is sleeved on the outside of the transmission square bar 1. The transmission square bar 1 is connected to the handle through the square sleeve 3a. The square sleeve 3a and the transmission square bar 1 are connected and fixed by a cylindrical pin 20. The square sleeve 3a and the pressure plate 13 can be designed as an integrated structure.The design of the square sleeve 3a increases the contact surface, making the connection with the handle more reliable and the rotation of the pressure plate 13 more stable. When positioning and installing the window lock mechanism, first insert the inner mounting seat 2A and the locking pressure plate 10 into the mounting hole 22 on the matching aluminum profile 21. At this time, the mounting panel of the aluminum profile 21 is between the locking pressure plate 10 and the isolation positioning ring 4. Then use the hexagonal wrench to penetrate the slot 14 opened on the pressure plate 13 to turn the locking screw 9 and press. Figure 2 In the design of the first embodiment shown, when the locking screw 9 rotates, the locking pressure plate 10 rises through the cooperation of the inclined surface 12 and the guide rib 18 and the guide groove 19, and the locking screw 9 swings upward in the through hole 7, and cooperates with the isolation positioning ring 4 to complete the clamping of the installation panel of the aluminum profile 21, thereby completing the positioning installation of the window lock mechanism. Figure 3 In the design of the second embodiment shown, the through hole 7 and the screw hole 10a on the locking plate 10 have the same inclination design as the inclined surface 12. When the locking screw 9 rotates, the locking plate 10 rises through the inclined surface 12, the inclined screw hole 10a and the through hole 7, as well as the guide rib 18 and the guide groove 19, and cooperates with the isolation positioning ring 4 to complete the clamping of the installation panel of the aluminum profile 21, and complete the positioning installation of the window lock mechanism. When the transmission square bar 1 rotates, the pressure plate 13 rotates at the same time. Under the action of the spring 16, the steel ball 17 cooperates with the slot hole 14 on the pressure plate 13 to make a crisp clicking sound, and also enhances the feel of the opening and closing operation of the window lock mechanism. The design of the pressure plate 13 also has a limiting effect on the locking screw 9, which facilitates the installation of the window lock mechanism. The embodiments described above are merely descriptions of preferred implementations of an improved positioning and mounting structure of a window lock mechanism of the present invention, and are not intended to limit the concept and scope of the invention. Without departing from the scheme of the present invention, various external modifications and improvements made by those skilled in the art to the technical scheme of the present invention should all fall within the protection scope of the improved positioning and mounting structure of a window lock mechanism of the present invention.
