[0002] Screens are the main means of mosquito prevention, theft prevention and protection. They are a channel for communication between people and the environment. They can effectively prevent mosquitoes, flies and other insects from flying or crawling in. While being ventilated and breathable close to nature, they can prevent close contact with mosquitoes and insects. At the same time, they can filter some debris entering the room to prevent debris in the air from polluting the room, making the home environment cleaner and more conducive to health. In order to facilitate the locking and opening of screens, screen locks are usually installed. The commonly used screen locks on the market have a complex locking structure, usually requiring three buttons to be used together, and the opening button has no locking function.

DETAILED DESCRIPTION

[0030] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0031] like Figure 1-7 As shown, a simple safety screen window lock of the present invention comprises a lock box 1, a lock cover 2 covering the bottom of the lock box 1, a locking component 3 and an unlocking control component 4.

[0032] The lock box 1 is provided with an installation cavity 5, and the locking assembly 3 and the unlocking control assembly 4 are installed in the installation cavity 5. The upper surface and one side wall of the lock box 1 are respectively provided with a first through hole 6 and a second through hole 7 which are connected with the installation cavity 5 and through which the locking assembly 3 and the unlocking control assembly 4 pass.

[0033] The locking assembly 3 includes a lock cylinder 32, a locking rod 34 and a locking button 33. The side wall of the lock cylinder 32 is provided with a convex rib 31 which can slide longitudinally along the first through hole 6. The locking rod 34 is sleeved in the lock cylinder 32. The locking button 33 is arranged above the lock cylinder 32 and passes through the first through hole 6 to be exposed to the lock box 1. The locking rod 34 is sleeved with a first elastic member 35 that provides a rebound force for the locking assembly 3. The bottom of the lock cover 2 is provided with a through cylinder 8 coaxial with the first through hole 6. The locking rod 34 passes through the through cylinder 8 and extends out of the through cylinder 8. The top of the lock rod 34 is provided with a limiting ring 36 of the first elastic member 35.

[0034] The unlocking control assembly 4 includes a sleeve 41, a rotating member 42, and a second elastic member 43. The side wall of the sleeve 41 is provided with an L-shaped locking groove 44 adapted to and locked with the convex rib 31. When the locking button 33 is pressed, the convex rib 31 slides longitudinally along the locking groove 44. When it slides to the corner of the L-shaped groove of the locking groove 44, the unlocking control assembly 4 slides transversely outward along the L-shaped groove 44 under the elastic force of the second elastic member 43 and then locks. When the sleeve 41 is pressed, the unlocking control assembly 4 slides transversely along the L-shaped groove 44. When it slides to the corner of the L-shaped groove, the locking assembly 3 pops out longitudinally outward under the elastic force of the first elastic member 35 to complete the unlocking.

[0035] The rotating member 42 includes a base 421 and a rotating shaft 422 connected in a stepped manner, and a first step 423 connected in multiple arc-shaped staggered positions is provided at the connection between the base 421 and the rotating shaft 422, and a second step 411 adapted to the first step 423 is provided on the inner wall of the sleeve 41. A limiting convex strip 412 for limiting the rotation angle of the rotating member 42 is provided on the inner wall of the sleeve 41, and an arc groove 4211 adapted to the limiting convex strip 412 is provided on the side wall of the base 421, and the arc of the arc groove 4211 is preferably 90 degrees. The rotating member 42 is sleeved in the sleeve 41, and a groove suitable for rotation by external force is provided on the top of the rotating member 42. When the rotating member 42 is driven by external force, the first step 423 rotates and moves downward along the second step 411, pressing the second elastic member 43, thereby locking the sleeve 41. At this time, the unlocking control component 4 cannot realize the unlocking function; when the rotating member 42 is rotated under the driving force of the reverse external force, the first step 423 engages with the second step 411, and the second elastic member 43 is reset. At this time, the unlocking control component 4 is reset and unlocked, and the unlocking function can be realized again.

[0036] A strip-shaped block 45 is provided on the lower surface of the sleeve 41, a slot 21 adapted to the block 45 is provided on the inner wall of the lock cover 2, the upper surface of the sleeve 41 is a plane, a boss 10 is provided on the top wall of the lock box 1, and the boss 10 and the slot 21 jointly fix the sleeve 41 to prevent it from shifting.

[0037] The lock box 1 and the lock cover 2 are respectively provided with a first mounting hole 11 and a second mounting hole 13 at both ends for fixed installation with the screen window frame. The first mounting hole 11 and the second mounting hole 13 are connected through holes, and can be installed in both directions. When installing on the reverse side, the second mounting hole 13 is used and installed with a machine screw and a nut; when installing on the front side, the first mounting hole 11 is used and installed with a self-tapping screw.

[0038] The lock box 1 is provided with a decorative cover 9 on its exterior, and a decorative cap 12 for decorating the keyhole is provided at the lower end of the through tube 8. The decorative cover 9 can cover the scratches or wear marks generated during the transportation of the lock box 1, and can also cover the mounting holes exposed on the surface of the lock box 1. At the same time, the decorative cap 12 is provided to increase the overall decorative effect of the lock body.

[0039] During installation, the screen lock is fixedly mounted on the window frame through the first mounting hole 11 or the second mounting hole 13. When the frame of the window frame is thick, the first mounting hole 11 on the lock box 1 can be used for installation; when the frame of the window frame is thin, the second mounting hole 13 on the lock cover 2 can be used for installation. To prevent possible scratches or wear during transportation, the decorative cover 9 is packaged separately and is mounted on the lock box 1 after other parts are installed.

[0040] When in use, the screen window is locked by pressing the locking button 33, and the screen window is unlocked by pressing the sleeve 41. When the locking and unlocking function is required, the rotating member 42 is rotated 90 degrees with a screwdriver. At this time, the sleeve 41 cannot be pressed to realize the unlocking function. The rotating member 42 is reversed 90 degrees, and the sleeve 41 resumes the press-to-unlock function.

[0041] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
