[0026] To facilitate users to lock the window to ensure aesthetics, there are existing special handles that can be locked and can open and close the window by rotation. Generally, the existing lockable handles achieve the locking or unlocking function of the handle rotation by setting a lock core inside the handle. In the related art, for the handle with a lock core, the lock core is always located beside the head of the handle, resulting in a relatively large volume of the handle head, requiring additional material costs, and the large-sized handle and lock core affect the installation efficiency and have poor aesthetics, unable to meet the user's usage requirements.
[0027] Therefore, referring to Figure 1 、 Figure 2 and Figure 3, a lockable handle proposed by the present utility model, includes a handle part 100, a lock core 200, a lock pin 300 and a lock seat 400. The handle part 100 is in a circular tubular shape, and the head of the handle part 100 is vertically communicated with an installation part, and the installation part and the handle part 100 form an "L" shape. A through installation hole 111 is provided at a corresponding position on the side of the handle part 100 away from the installation part, and the installation hole 111 communicates with the inside of the installation part. The lock core 200 passes through the installation hole 111 and is movably arranged in the installation part, and the lock core 200 can make a linear reciprocating motion along the axis of the installation part. The lock pin 300 is arranged on the side of the installation part away from the lock core 200, and the lock pin 300 is fixedly connected to the lock core 200. The lock seat 400 is used for installing on a window, the installation part is inserted into the lock seat 400, and the handle part 100 can rotate along the axis of the installation part. A locking component is arranged in the lock seat 400 for locking the window, and the handle part 100 rotates to open and close the locking component. A receiving groove 421 is arranged in the lock seat 400, a limiting notch 422 is arranged on the side wall of the receiving groove 421, a limiting boss 310 is arranged on the side wall of the lock pin 300, the lock pin 300 can be inserted into the receiving groove 421, and the limiting boss 310 is clamped into the limiting notch 422 to limit the rotation of the handle part 100. It can be understood that the user can lock or open the window by rotating the handle part 100, and can push or pull the window through the handle to ensure its basic functions. When locking is required, the user rotates the handle part 100 to a preset position, presses the lock core 200 by hand, and then drives the lock pin 300 to move and insert into the receiving groove 421. The limiting boss 310 and the limiting notch 422 are just clamped, realizing the locking of the handle part 100. At this time, the user cannot rotate the handle part 100, nor can the window be unlocked or locked. When unlocking the handle, the user inserts the key into the lock core 200, drives the lock core 200 to extend out of the installation hole 111, the lock pin 300 follows and moves, and disengages from the receiving groove 421. The limiting boss 310 and the limiting notch 422 are separated, and the handle part 100 is unlocked and can be rotated to open and close the window.
[0028] It is easy to understand that the locking mechanism composed of the lock core 200 and the lock pin 300 drives the movement of the lock pin 300 through the linear reciprocating motion of the lock core 200, and then cooperates with the locking component in the lock seat 400 to realize the reliable locking of the window. At the same time, the limiting boss 310 on the side wall of the lock pin 300 cooperates with the limiting notch 422 on the side wall of the receiving groove 421 of the lock seat 400, effectively restricting the rotation of the handle part 100 and enhancing the stability of locking. By adopting the structure of the middle-mounted lock core 200, replacing the lock core 200 arranged on the lock seat 400, the volume of the handle is significantly reduced. Compared with the traditional structure, its compact design not only saves the material cost, but also improves the aesthetics of the window handle, making it more adaptable to the aesthetic needs of modern homes. On the other hand, the installation process is simpler and faster, without complex installation steps, reducing the installation difficulty and improving the installation efficiency.
[0029] Referring to Figure 1 、 Figure 2 and Figure 3 , the lock base 400 is composed of an upper base 410 and a lower base 420. The upper base 410 is fixedly connected to the lower base 420 and is close to the handle part 100. The lower base 420 is provided with a through central hole 411, and the central hole 411 is concentric with the receiving groove 421. The installation part passes through this central hole 411, making the structure of the lock base 400 more stable. At the same time, the installation part can accurately align with the receiving groove 421, improving the installation accuracy and stability.
[0030] Referring to Figure 1 、 Figure 2 and Figure 3 , further, the lower base 420 is provided with a positioning groove 423. The end of the installation part extends into the positioning groove 423.

Through the dual action of the axial retaining ring 320 and the limit washer 330, the connection stability between the handle part 100 and the lock base 400 is enhanced, effectively preventing the handle part 100 from accidentally falling off during use.
[0031] Referring to Figure 1 , a cylindrical positioning stud 424 extends upward from the center of the positioning groove 423, and the middle part of the positioning stud 424 is the receiving groove 421. This makes the position of the receiving groove 421 more definite. At the same time, it also increases the strength of the lock base 400 and improves the overall stability.
[0032] Referring to Figure 1 、 Figure 2 and Figure 3 , the lock base 400 further includes a panel 430. The panel 430 has a trough-like structure with an opening at the bottom. The inner side wall is provided with a limit groove 431. The lower base 420 is provided with a limit elastic piece 425. The panel 430 covers the upper base 410 and the lower base 420, and the limit elastic piece 425 snaps into the limit groove 431 to prevent the panel 430 from detaching, increasing the aesthetics of the lock base 400. At the same time, the cooperation between the limit elastic piece 425 and the limit groove 431 ensures the stable installation of the panel 430 and improves the overall reliability. Further, the peripheral wall of the upper base 410 is provided with a limit step 412, and the side wall of the panel 430 is provided with a limit hole corresponding to the position of the limit step 412. A flat-end set screw 415 passes through the limit hole. A steel ball 413 is embedded in the limit step 412. A limit spring 414 is provided between the limit step 412 and the inner side wall of the panel 430. One end of the limit spring 414 abuts against the steel ball 413, and the other end abuts against the flat-end set screw 415. The cooperation between the limit spring 414 and the steel ball 413 ensures the stability of the panel 430 under external forces such as vibration.
[0033] Referring to Figure 2 and Figure 3 On the inner side wall of the installation part, there is a relief groove 112. When the handle part 100 is in the unlocked state, the limit boss 310 is separated from the limit notch 422 and is snapped into the relief groove 112, providing a storage position for the limit boss 310 in the non-locked state, avoiding interference between the limit boss 310 and other parts of the lock base 400 in the unlocked state, and improving the operation flexibility of the handle part 100.
[0034] Referring to Figure 1 、 Figure 2 and Figure 3 The lock base 400 is provided with a fixing hole 440 for passing through a fastener to be fixed to the window, so that the lock base 400 can be firmly installed on the window, improving the overall safety. Further, the driving part of the locking assembly passes through the lock base 400 and the accommodating groove 421, and the lock pin 300 is fixedly connected to the driving part to drive the locking assembly to lock or unlock.
[0035] The present utility model also proposes a window, which includes the lockable handle described above. By adopting the lockable handle with the above design, the window not only has higher safety and stability, but also improves the overall aesthetics and the user experience.
