[0028] In order to better understand the purpose, structure and function of this utility model, Figures 1 to 8 , a screen window lock of the utility model is further described in detail.

[0029] like Figures 1 to 8 As shown, a screen lock according to an embodiment of the present invention includes a locking assembly, a transmission assembly 200, a rotating wheel assembly 300, a first housing 400, and a second housing 500. The locking assembly, the transmission assembly 200, and the rotating wheel assembly 300 are disposed between the first housing 400 and the second housing 500, and the first housing 400 and the second housing 500 are detachably connected.

[0030] The locking assembly of the present invention includes a push-pull component 110, a rotating component 120, and a locking block component 130. The push-pull component 110 is fixedly connected to the rotating component 120, which is in turn fixedly connected to the locking block component 130. A transmission fixing slot 140 is also provided on the rotating component 120. The push-pull component 110, the locking block component 130, and the transmission fixing slot 140 are disposed on the outer circumference of the rotating component 120. A rotating shaft 121 is provided on the end surface of the rotating component 120, which is rotationally connected to both the first housing 400 and the second housing 500. The push-pull component 110, the rotating component 120, the locking block component 130, and the transmission fixing slot 140 can be designed as a non-detachable unit, thereby increasing the strength of the locking assembly and reducing the probability of failure.

[0031] A runner shaft 330 is also provided in the middle of the end face of the runner assembly 300. In addition, the face of the runner assembly 300 facing the transmission assembly 200 is a first runner end face 350, and the first runner end face 350 is provided with a runner fixing groove 310. An indicator mark portion 320 is also provided on the upper outer peripheral surface of the runner assembly 300. The indicator mark portion 320, the runner shaft 330 and the runner fixing groove 310 are in a straight line. In one embodiment, a plurality of anti-slip teeth 340 are also provided on the outer peripheral surface of the runner assembly 300.

[0032] A groove fixing block 210 is provided at one end of the transmission assembly 200 near the locking assembly. The groove fixing block 210 can be inserted into the transmission fixing groove 140. A fixing protrusion 220 is provided on the side opposite the groove fixing block 210. The fixing protrusion 220 can be received in the rotating wheel fixing groove 310 and is parallel to the axis of the transmission assembly 200.

[0033] In the present invention, a locking block groove 410 is provided on the first housing 400, and the locking block groove 410 is used for the locking block component 130 to pass through when unlocking and locking. In addition, the first housing 400 is also provided with a sliding groove 420. Transmission sliders 230 are also provided on both sides of the transmission assembly 200, and the transmission sliders 230 can slide in the sliding groove 420. A rotating part embedding groove 430 is also provided in the middle of the first housing 400, and the rotating part 120 is embedded in the rotating part embedding groove 430. The groove fixing block 210 is also provided in the rotating part embedding groove 430; a rotary wheel rotating part is provided on one end of the first housing 400 close to the transmission assembly 200; a first shaft support part 440 is provided on the rotary wheel rotating part, and the first shaft support part 440 is rotatably connected to the rotary wheel shaft 330. A locking block opening 431 and a fixing block opening 432 are provided in the axial direction of the rotating portion embedding groove 430 , and a first rotating groove 433 is provided in a direction perpendicular to the axis of the rotating portion embedding groove 430 . The first rotating groove 433 is rotatably connected to the rotating shaft 121 .

[0034] Furthermore, the front of the second housing 500 is provided with an operating groove 510, and the middle portion of the operating groove 510 is provided with a push-pull opening 520, which can pass through the push-pull member 110. In addition, the upper portion of the back surface of the second housing 500 is provided with a lock block receiving groove 530, which can accommodate the lock block member 130; at the same time, two second rotation grooves 540 are provided below the lock block receiving groove 530, which are rotatably connected to the rotation shaft 121. A transmission platform 550 is provided below the second rotation groove 540, which is slidably connected to the transmission assembly 200. A transmission stopper 551 is also provided in the transmission platform 550. A transmission center slot 240 is provided in the middle of the transmission assembly 200, and the transmission stopper 551 is located in the transmission center slot 240. A runner accommodating slot 560 is also provided below the transmission platform 550. The center portion of the runner accommodating slot 560 is used to accommodate the runner assembly 300. A second shaft support 561 is provided above the runner accommodating slot 560, which is rotatably connected to the runner shaft 330. A third shaft support 562 is provided below the runner accommodating slot 560, which is rotatably connected to the runner shaft 330 and slidably connected to the first shaft support 440. A runner indicator display window 563 is also provided at the bottom of the runner accommodating slot 560.

[0035] As will be appreciated, a first lock body fixing component 570 is further provided on the side of the second housing 500 opposite the lock block receiving slot 530, and a second lock body fixing component 580 is further provided on the side of the second housing 500 opposite the wheel receiving slot 560. A lock body panel 590 is also provided on the side of the second housing 500 opposite the first housing 400. The lock body panel 590 is fixedly connected to the second housing 500 and serves to enhance the appearance of the screen lock. During installation, the first lock body fixing component 570 and the second lock body fixing component 580 ensure a stable attachment of the screen lock to the screen window.

[0036] During use, when the screen lock is in a locked state, the locking block component 130 passes through the locking block through-hole 431, so that the screen is locked and cannot be opened. If the screen lock needs to be opened, the wheel assembly needs to be rotated and the indicator mark part 320 needs to be rotated to the wheel marking display window 563. At this time, the wheel fixing groove 310 rotates to the bottom of the fixed protrusion 220. Due to the action of gravity, the transmission assembly 200 slides downward and the fixed protrusion 220 enters the wheel fixing groove 310. At this time, the groove fixing block 210 disengages from the transmission fixing groove 140, so that the rotating component 120 can rotate, that is, the push-pull component 110 can be pulled downward, driving the lock block component 130 to move into the inside of the first shell 400, thereby unlocking the screen lock. If the indicator mark part 320 is not rotated to the wheel marking display window 563, the fixed protrusion 220 will not enter the wheel fixing groove 310, the groove fixing block 210 will not disengage from the transmission fixing groove 140, and the locking assembly cannot be pushed or pulled, and it is in a locked state.

[0037] When the screen lock is in the unlocked state and needs to be locked, the push-pull component 110 is pushed upward, and the lock block component 130 will move to the outside of the first shell 400 to form a locked state, but it is also necessary to rotate the wheel assembly 300 and rotate the indicator mark part 320 to a position outside the wheel marking display window 563. At this time, due to the extrusion effect, the fixed protrusion 220 will be squeezed out of the wheel fixing groove 310, so that the transmission assembly 200 slides upward. At this time, the groove fixing block 210 will enter the transmission fixing groove 140, and the push-pull component 110 cannot push or pull, thereby realizing the locking function of the screen lock.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
