[0067] The lock core 4 includes a lock core rotating shaft 41 , a lock core guide shaft 42 , a lock core positioning member 43 and a lock core shifting piece 44 .

[0068] On the top surface of the lock core rotating shaft 41, there is a first keyhole 411 arranged along the length direction of the lock core rotating shaft 41. On the side surface of the lock core rotating shaft 41, there is a paddle hole 412 arranged perpendicular to the length direction of the lock core rotating shaft 41. The first keyhole 144 communicates with the paddle hole 412. On the bottom surface of the lock core rotating shaft 41, there are a connecting shaft 413 and a first limiting portion 414. On the outer side surface of the lock core rotating shaft 41, there is a positioning ring groove 415, which is adapted to the positioning buckle 129 on the lock core pressing cover 127. The lock core rotating shaft 41 is arranged in the lock core groove 121 on the lock core seat 12. Through the cooperation of the positioning buckle 129 and the positioning ring groove 415, the lock core pressing cover 127 and the lock core rotating shaft 41 are fixed.

[0069] On the top surface of the lock core guide shaft 42, there are a connecting shaft hole 421 and a second limiting portion 422 respectively adapted to the connecting shaft 413 and the first limiting portion 414. On the sealing plate 13, there is a connecting shaft positioning hole 133. The connecting shaft 413 passes through the connecting shaft hole 421, and the lower end of the connecting shaft 413 is arranged in the connecting shaft positioning hole 133. The first limiting portion 414 cooperates with the second limiting portion 422 to connect the lock core guide shaft 42 with the lock core rotating shaft 41 and rotate synchronously with the lock core rotating shaft 41. On the side surface of the lock core guide shaft 42, there is a guiding groove 423 spirally arranged on its side surface.

[0070] The lock core positioning member 43 includes a positioning ring 431, a locking member 432 arranged on the outer side surface of the positioning ring 431, and a pin shaft 433. On the side surface of the positioning ring 431, there is a positioning pin shaft hole. The lock core guide shaft 42 is rotatably arranged in the positioning ring 431. The pin shaft 433 is arranged in the positioning pin shaft hole. One end of the pin shaft 433 is slidably arranged in the guiding groove 423. The locking member 432 is arranged in the locking member hole 213 and is arranged to move up and down. The locking member 432 is oval and cooperates with the locking member hole 213, having good locking effect and stability. A plurality of paddle limiting grooves 123 are arranged up and down opposite to the locking member hole 213, which is convenient for positioning the rotation position of the handle.

[0071] The lock core paddle 44 is telescopically arranged radially along the lock core rotating shaft 41 in the paddle hole 412. The lock core paddle 44 includes an upper paddle and a lower paddle. A return spring 441 is arranged between the upper paddle and the lower paddle and the paddle hole 412. There is a second keyhole 442 on the lock core paddle 44. As the key is inserted into the second keyhole 442, the lock core paddle 44 retracts into the paddle hole 412.

[0072] The working process of the present invention is as follows:

[0073] The key 5 is inserted into the first keyhole 411 of the lock core 4. As the key 5 is inserted, the key 5 is inserted into the second keyhole 442, and the lock core flap 44 retracts into the lock core rotating shaft 42, and the lock core 4 can rotate within the lock core groove 121. The user rotates the key 5, drives the lock core rotating shaft 41 to rotate through the lock core flap 44, drives the lock core guide shaft 42 to rotate through the lock core rotating shaft 41. The pin shaft 433 on the lock core positioning member 43 slides upward within the guiding groove 423 on the lock core guide shaft 42, driving the locking member 432 on the lock core positioning member 43 to move upward within the locking member hole 213, disengaging from the locking member hole 213, and unlocking the handle 1 and the base 2. At the same time, the upper flap retracts into the lock core rotating shaft 41, and the lower flap engages with the limiting convex ring 122, keeping the lock core 4 in the unlocked state. The user drives the square shaft to rotate by rotating the handle 1 to open and close the doors and windows.

[0074] When it is necessary to lock the handle 1 and the base 2, rotate the key in the reverse direction. The lock core rotating shaft 41 drives the lock core guide shaft 42 to rotate in the reverse direction. The pin shaft 433 and the locking member 432 move downward, and the locking member 432 is inserted into the locking hole 213, relocking the handle 1 and the base 2. At the same time, the upper flap extends out of the lock core rotating shaft 41 and engages with the limiting convex ring 122, keeping the lock core 4 in the locked state.

[0075] Compared with the prior art, the handle lock for sliding doors and windows provided by the present invention has the following advantages:

[0076] (1) The lock core structure includes a lock core rotating shaft, a lock core guide shaft, a lock core positioning member, and a lock core flap. The lock core structure is simple. Through the synchronous rotation of the lock core rotating shaft and the lock core guide shaft, the pin shaft on the lock core positioning member slides within the guiding groove on the lock core guide shaft, realizing the up and down movement of the lock core positioning member within the locking hole on the base, thereby realizing the locking or unlocking of the handle and the base. The lock core structure is simple and reliable, extending the service life of the door and window handle lock.

[0077] (2) A lock core groove is provided within the lock core seat of the handle, and a limiting convex ring is provided within the lock core groove. The limiting convex ring can engage with the upper flap or the lower flap after the key is pulled out, keeping the locking member and the locking member hole locked. When the user uses it, there is no need to keep holding the handle, improving the user experience;

[0078] (3) The handle includes two handle shells, a lock core seat, and a sealing plate that are snap-fitted. The handle shell can be made by stamping, with low production costs and simple production steps. The handle shell encloses a lock core cavity, and the sealing plate is arranged on the bottom surface of the lock core cavity and can be welded to the handle shell, with convenient connection; the various components of the handle are produced separately and are easy to assemble, greatly reducing the production cost and the production difficulty of the handle.

[0079] The present invention is not limited to the above-mentioned optimal embodiments. Anyone should be aware that structural changes made under the inspiration of the present invention, as long as they have the same or similar technical solutions as the present invention, all fall within the protection scope of the present invention.
