[0021] As a further solution of the utility model, two handle cylinders 9 are slidably arranged on the steel sheet 4, and the top of the handle cylinder 9 is fixedly connected to the bottom of the handle 3, and cylindrical notches 10 are respectively provided on both sides of the handle cylinder 9 contacting the steel sheet 4, two steel sheet clamping holes 11 are provided on the steel sheet 4, and the handle cylinder 9 is slidably arranged in the steel sheet clamping holes 11, and vertical springs 12 are respectively provided on the side where the two handle cylinders 9 are close to each other, and the vertical springs 12 are slidably arranged in the steel sheet clamping holes 11, and a handle hole 13 is provided on the lock surface 1 The handle 3 is arranged in the handle hole 13. By arranging mechanisms such as the handle cylinder 9 and the steel sheet clamping hole 11, the limitation that the traditional screen window lock can only be locked by the handle or button is broken, which is convenient for users to use. The arrangement of mechanisms such as the vertical spring 12 and the cylindrical notch 10 makes the contact between the lock body closer and improves the stability of the window. The design of the two handle cylinders 9 makes the window more stable and can effectively avoid the window shaking or opening due to poor contact or looseness, thereby improving safety.
[0022] As a further solution of the utility model, two switch protrusions 14 are respectively provided at one end of the control switch 2, and the two switch protrusions 14 are respectively located on both sides of the code wheel 6, and code wheel notches 15 are respectively provided on both sides of the code wheel 6, and the switch protrusion 14 extends into the code wheel notch 15 at one end away from the handle 3. By providing mechanisms such as the code wheel notch 15 and the switch protrusion 14, the locking of the lock body is more tight, and the safety of the window is improved. The provision of mechanisms such as the transverse spring 16, the protrusion, and the cover plate notch 17 makes the window more secure, which can effectively prevent damage and prying by intruders, thereby improving the safety of the window.
[0023] As a further solution of the utility model, a transverse spring 16 is arranged between the two switch protrusions 14, and the two ends of the transverse spring 16 are respectively connected to the control switch 2 and the lock surface 1, a protrusion is arranged on the top of the rear cover 5, a cover groove 17 is opened on the protrusion, and a lock core round plug 18 is arranged on the bottom of the lock cylinder 7, and the cover groove 17 is adapted to the lock core round plug 18. By arranging mechanisms such as the protrusion and the lock core round plug 18, the hand speed lock cylinder 7 can be effectively prevented from being destroyed or damaged by external force. The design is ingenious, which improves the stability and safety of the window, can effectively prevent intrusion, and optimizes the user experience while ensuring safety.
[0024] As a further solution of the utility model, a switch hole 19 is opened on the lock surface 1, and the lock core 7 is arranged in the switch hole 19. A limiting member is provided on the side of the steel sheet 4 away from the password wheel 6. The limiting member is fixedly connected to the lock surface 1 by installing screws 20. By setting the limiting member, the sliding of the steel sheet 4 can be limited to avoid excessive sliding affecting subsequent operations, thereby improving the stability and safety of the lock body.
[0025] As a further solution of the utility model, the two steel sheet clamping holes 11 are two different irregular long holes, and there are convex corners in the steel sheet clamping holes 11 to clamp with the cylindrical notch 10. By setting the steel sheet clamping holes 11 as long holes, the steel sheet clamping holes 11 can be used to control the handle cylinder 9 according to different needs of opening or closing the screen lock, so that the lock body is more suitable for the window, and the stability and safety of the window are enhanced.
[0026] The working principle of the double-insertion screen window lock provided by the utility model is as follows:
[0027] When opening, the control switch 2 is pushed in the switch hole 19 to the side away from the handle 3, driving the steel sheet 4 to slide, separating the convex corner in the steel sheet clamping hole 11 from the shorter cylindrical notch 10, and the handle cylinder 9 loses the clamping force of the steel sheet 4, and bounces upward under the expansion action of the vertical spring 12. At the same time, due to the limitation of the handle hole 13, the handle cylinder 9 pops the handle 3 out of the handle hole 13, and the two handle cylinders 9 are disengaged from the lock hole, and are limited at the bottom of the longer cylindrical notch 10 to prevent the handle 3 from falling out of the handle hole 13. When the handle 3 pops out of the handle hole 13, the control switch 2 is released, and under the action of the transverse spring 16, the control switch 2 slides back to its original position in the switch hole 19, and the steel sheet clamping hole 11 contacts the longer cylindrical notch 10 on the handle cylinder 9. At this time, the screen lock is in the open state;
[0028] When locking, press the handle 3, so that the steel sheet clamping hole 11 and the shorter cylindrical notch 10 on the handle cylinder 9 are clamped, so as to fix the handle cylinder 9 and the steel sheet 4. At this time, the bottom ends of the two handle cylinders 9 slide into the lock hole to lock the screen window lock;
[0029] When reverse locking, the lock core 7 can be rotated by inserting the key 8, and the lock core round plug 18 at the bottom of the lock core 7 can be screwed into the cover plate slot 17 to limit the sliding of the control switch 2 in the switch hole 19, thereby forming a reverse lock. The code wheel slot 15 on the code wheel 6 can also be rotated to the side away from the switch protrusion 14, so that the sliding distance of the control switch 2 is limited, and the handle cylinder 9 cannot slide in the steel sheet card hole 11, thereby forming a reverse lock. When unlocking, the reverse operation can be performed to unlock.
[0030] Compared with the related art, the double-insertion screen window lock provided by the utility model has the following beneficial effects:
[0031] The utility model provides a double-insertion screen window lock, which is simpler through the design of the handle 3, does not require greater strength and hand coordination during operation, and is convenient for use by the elderly and children. By arranging mechanisms such as the handle cylinder 9 and the steel sheet clamping hole 11, the limitation that the traditional screen window lock can only be locked by the handle or button is broken through, which is convenient for users to use. The arrangement of mechanisms such as the vertical spring 12 and the cylindrical notch 10 makes the contact between the lock bodies closer and improves the stability of the window. The design of the two handle cylinders 9 makes the stability of the window better, and can effectively avoid the window shaking or opening due to poor contact or looseness, thereby improving safety. By arranging mechanisms such as the password wheel notch 15 and the switch convex rod 14, the locking of the lock body is more strict, which improves the safety of the window. The transverse spring 16, The provision of mechanisms such as the protrusion, the cover plate notch 17 makes the window more solid, can effectively prevent damage and prying by intruders, and improves the safety of the window. By providing mechanisms such as the protrusion and the lock core round plug 18, the hand-speed lock core 7 can be effectively prevented from being destroyed or damaged by external forces. The design is ingenious, improves the stability and safety of the window, and can effectively prevent intrusion. While ensuring safety, it also optimizes the user experience. By providing a limiter, the sliding of the steel sheet 4 can be limited to prevent excessive sliding from affecting subsequent operations, thereby improving the stability and safety of the lock body. By providing the steel sheet clamping hole 11 as an elongated hole, the steel sheet clamping hole 11 can be used to control the handle cylinder 9 according to different requirements for opening or closing the screen window lock, so that the lock body is more suitable for the window, thereby enhancing the stability and safety of the window.
