DETAILED DESCRIPTION
[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0022] like Figure 1-5 As shown, a new window lock provided by an embodiment of the utility model comprises a lock shell 1, a lock core assembly 8 is inserted into a through hole in the middle of the lock shell 1, the lock core assembly 8 comprises a rotating head 16 inserted into the lock shell 1, and one end of the rotating head 16 is keyed to a turntable 17, a plurality of equidistant and annularly distributed card grooves 18 are arranged on the outer wall of the turntable 17, a special-shaped socket 20 is arranged in the middle of one side of the turntable 17, and a transmission shaft 9 is inserted into the special-shaped socket 20, mounting grooves 10 are arranged on both sides of the interior of the lock shell 1, and a spring 11 is arranged inside the mounting groove 10, a limit pin 12 is fixedly arranged at one end of the spring 11, and the limit pin 12 is clamped in the interior of the card groove 18.
[0023] Specifically, in the present embodiment, a lock case 1 is included, which is made of an integrated structure. A lock core assembly 8 is inserted into a through hole in the middle of the lock case 1. The lock core assembly 8 includes a rotating head 16 inserted into the lock case 1, and a turntable 17 is keyed at one end of the rotating head 16. The turntable 17 is driven to rotate by the rotation of the rotating head 16, and the turntable 17 drives the transmission shaft 9 to rotate. The outside of the rotating head 16 can also be used in conjunction with a handle, and it is only necessary to ensure that the socket of the handle is compatible with the structure of the rotating head 16. A plurality of equidistant and annularly distributed card grooves 18 are provided on the outer wall of the turntable 17. A special-shaped socket 20 is provided in the middle of one side of the turntable 17, and the transmission shaft 9 is inserted into the inside of the special-shaped socket 20. The special-shaped socket 20 is a circular structure, and the special-shaped socket 20 is a cylindrical structure. Right-angle holes are set at the four corners of the opening 20, so that the transmission shaft 9 corresponding to the shape thereof can cooperate, ensuring the stability of the connection between the transmission shaft 9 and the special-shaped socket 20. Through the movement of the lock core assembly 8 inside the lock shell 1, the movement is transmitted by the transmission shaft 9, so that the transmission components inside the window are moved to achieve the locking and opening of the doors and windows. Installation grooves 10 are set on both sides of the interior of the lock shell 1, and a spring 11 is set inside the installation groove 10. A limit pin 12 is fixedly set at one end of the spring 11. The limit pin 12 is clamped in the inside of the card slot 18. When the turntable 17 rotates, the limit pin 12 squeezes the spring 11, so that the limit pin 12 jumps in the card slot 18 at different positions, thereby achieving the limitation of the turntable 17 and ensuring the reliability of the window lock when in use.
[0024] The utility model provides a novel window lock, in which a lock core assembly 8, a rotating head 16 and a rotating disk 17 are of a split structure, which is convenient for disassembly and replacement. At the same time, a lining plate 6 is arranged on the outer side of the rotating head 16, which effectively guides and protects the rotating head 16, thereby improving the service life of the window lock. The cooperation of the spring 11, the limit pin 12 and the card slot 18 on the rotating disk 17 makes the operation of the lock core assembly 8 more reliable.

The operator can insert his hand into the finger groove 3 and forcefully push open the decorative cover 2, so that the decorative cover 2 is separated from the lock shell 1, thereby realizing the quick disassembly of the decorative cover 2.
[0026] As another embodiment provided by the utility model, a through hole is provided at the center of the front side of the decorative cover 2, and a ring 4 with a protruding structure is provided on the outside of the through hole. The ring 4 is sleeved on the outside of the lock core assembly 8. The ring 4 also guides the lock core assembly 8 during rotation, thereby providing good protection for the lock core assembly 8.
[0027] In another embodiment of the utility model, a lining plate 6 is provided inside the lock shell 1, and a bayonet 5 is provided on the outer walls on both sides of the lock shell 1, and a clamping block 14 matching the bayonet 5 is provided on the outer walls on both sides of the lining plate 6. The clamping block 14 is clamped in the inside of the bayonet 5 to achieve fixed installation of the lining plate 6 inside the decorative cover 2. A guide ring 15 that is sleeved on the outside of the rotating head 16 is welded on the outer wall on one side of the lining plate 6, and the guide ring 15 is used to achieve a guiding and supporting function for the rotating head 16 when it rotates.
[0028] As another embodiment provided by the utility model, guide columns 7 are provided on the upper and lower parts of the lock shell 1, and the guide columns 7 are hollow structures. The upper and lower guide columns 7 are arranged in groups of three, and screws are inserted into the inside of the guide columns 7 to achieve fixed installation of the lock shell 1 on doors and windows.
[0029] In another embodiment provided by the utility model, reinforcing ribs 13 are provided on the top and bottom of the lock shell 1, which improves the structural strength of the lock shell 1 and ensures the stability of the lock shell 1. A marking sticker 19 is provided on the outer wall of one side of the turntable 17, so that better alignment can be achieved when people assemble the lock core assembly to avoid assembly errors.
