[0040] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar units or units having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0041] The implementation of this application is as follows Figure 1-7 As shown. A window clip child lock 3 is provided at the window clip 2 of the screen window 1. Considering the side pull of the screen window 1, the window clip child lock 3 can be placed on one side of the window clip 2. In other words, the window clip child lock 3 can be provided at any position on the window clip 2 for the convenience of the customer.

[0042] from Figure 2 It can be seen that after the frame buckle box 12 of the screen window 1 is opened, it can be seen that the end of the window clip child lock 3 is stuck at the bottom of the frame 11. The lock tongue 31 of the window clip child lock 3 extends out of the buckle cover 22 on both sides of the window clip 2, and then is stuck on the frame 11. The buckle cover 22 is also provided with a first through hole 221 that matches the extension of the lock tongue 31. The cross-sectional shape of the first through hole 221 is consistent with the cross-sectional shape of the lock tongue 31, and the size difference is very small. The first through hole 221 not only facilitates the extension and retraction of the lock tongue 31, but also plays a role in positioning and limiting the lock tongue 31. That is, due to the design of the first through hole 221, the lock tongue 31 can be extended horizontally or vertically from the window clip 2 (depending on whether the window clip 2 is horizontal or vertical).

[0043] like Figure 5 As shown, the window clip child lock 3 includes a lock body 35, a push plate 33 that slides inside the lock body 35, a connecting plate 32 connected to the lock tongue 31, and a knob 36 for locking the window clip child lock 3. The lock body 35 is provided with a first sliding cavity, and the push plate 33 slides in the first sliding cavity. A first installation avoidance hole 351 is provided on the front of the lock body 35, and a mounting hole is provided on the other side of the lock body 35. When the lock body 35 needs to be installed, a bolt is used to pass through the first installation avoidance hole 351 and use the mounting hole to install the lock body 35 to the installation location to be installed. In this embodiment, the installation location to be installed is on the window clip 2. The provision of the first installation avoidance hole 351 can facilitate the installation of the lock body 35. Since the lock body 35 is a shell-like structure, if it is installed directly with bolts, the shell-like structure of the lock body 35 may be squeezed and damaged, and the installation may also be unstable.

[0044] The lock body 35 also has a second mounting clearance hole 352 on one side of its housing, and a raised shaft slot on the other side of its housing corresponding to the second mounting clearance hole 352. The knob 36 is mounted on the shaft slot through the second mounting clearance hole 352, and rotates within the shaft slot. The knob 36 is mounted to the lock body 35 through the second mounting clearance hole 352. The main body of the knob 36 is positioned within the lock body 35, minimizing its protrusion from the lock body 35 to prevent children from accidentally touching it and reducing the risk of accidental activation. The knob 36 is also engraved with a letter, a cross, or other intaglio pattern to facilitate user rotation.

[0045] It is conceivable that the knob 36 does not necessarily have to be limited by the limiting arc plate 353, and can also be fastened by bolts or the like.

[0046] pass Figure 6 As can be seen from the cross-sectional view, the shaft groove is further provided with a limiting arc plate 353, and the limiting arc plate 353 limits the rotation range of the knob 36.

[0047] A limiting column 361 is provided on the knob 36, and the limiting column 361 is used to limit the sliding insertion of the push plate 33. The limiting arc plate 353 controls the rotation range of the knob 36 by limiting the limiting column 361. On the other hand, the limiting arc plate 353 can cooperate with the limiting column 361 to limit the push plate 33. Figure 6 As can be seen in the figure, when the limiting post 361 is parallel to the lock body 35, the pressing plate 33 is not affected by the knob 36 and can slide on its own. It is conceivable that when the knob 36 is rotated to another position of the limiting arc plate 353, the end of the limiting post 361 will have a chance to abut the end of the pressing plate 33, thereby limiting the pressing plate 33.

[0048] The end of the limiting post 361 is provided with a positioning groove 362, and the positioning groove 362 is used to abut the end of the pressing plate 33. The positioning groove 362 is used to increase the contact area between the limiting post 361 and the end of the pressing plate 33, thereby improving the positioning effect.

[0049] from Figure 6 It can also be seen that the interior of the housing of the lock body 35 is further provided with an abutting protrusion 355, and the abutting protrusion 355 is arranged in the middle of the lock body 35. It is conceivable that Figure 6A spring may be provided between the abutting protrusion 355 and the pressing plate 33. This arrangement allows the window clip child lock 3 to be locked in its natural state under the action of the spring; when the pressing plate 33 is pressed, the locking tongue 31 is driven to retract into the window clip 2, thereby pulling the window clip 2. It is conceivable that the spring may also be provided directly between the two pressing plates 33, in which case the abutting protrusion 355 is not required.

[0050] from Figure 7 As can be seen from the figure, the knob 36 is connected to the lock body 35 via a bolt.

[0051] As can also be seen from this figure, one end of the locking tongue 31 is adapted to engage with the buckle cover 22. The buckle cover 22 defines a first through-hole 221, the dimensions of which are compatible with the locking tongue 31. The end of the locking tongue 31 that engages with the buckle cover 22 also has an inclined end surface, designed to facilitate insertion of the locking tongue 31 into the first through-hole 221. The other end of the locking tongue 31 is connected to the connecting plate 32.

[0052] The connecting plate 32 is provided with two connecting points, one for connecting the locking tongue 31 and the other for connecting the pressing plate 33. It is conceivable that the two connecting points may also be one.

[0053] A second sliding cavity 211 is defined inside the window clip body 21 , and the second sliding cavity 211 is used for the connecting plate 32 and the locking tongue 31 to slide therein.

[0054] from Figure 7 As can be seen, the cross-sectional shape of the connecting plate 32 is consistent with that of the second sliding cavity 211. This structural arrangement ensures more accurate sliding of the connecting plate 32 within the window clip body 21. It is conceivable that the locking tongue 31 could be directly connected to the pressing plate 33. However, in this case, the locking tongue 31 would need to be constantly moving, resulting in poor overall structural stability. Using the connecting plate 32 as an intermediate drive not only stabilizes the connection of the locking tongue 31 at this end, ensuring a straight force distribution, but also reduces the design and installation complexity of the overall structure. It is conceivable that, since the cross-sectional shape of the connecting plate 32 is consistent with that of the second sliding cavity 211, the connection between the connecting plate 32 and the pressing plate 33 could be achieved through a circular hole and positioning post, and / or the connection between the connecting plate 32 and the locking tongue 31 could be achieved through a circular hole and positioning post. This connection method avoids irreversible structural deformation caused by a fixed connection.

[0055] The connection between the connecting plate 32 and the pressing plate 33 is in the form of a positioning column and a positioning hole 321. Of course, they can also be connected by bolts. The lock body 35 and the window clip body 21 are respectively provided with a first sliding avoidance hole 356 and a second sliding avoidance hole 23 at the position corresponding to the positioning column. The first sliding avoidance hole 356 and the second sliding avoidance hole 23 facilitate the positioning column to drive the connecting plate 32 to move. Figure 6 and Figure 7 As can be seen, the first sliding avoidance hole 356 and the second sliding avoidance hole 23 are elongated holes. This arrangement not only facilitates the movement of the connecting plate 32 by the pressing plate 33, but also serves as a position limiter, restricting vertical movement while also preventing the pressing plate 33 from separating from the lock body 35.

[0056] The pressing plate 33 is arranged inside the lock body 35 and can slide relative to the lock body 35. A positioning column is provided at one end of the pressing plate 33 for connecting to the connecting plate 32. An installation avoidance notch 331 is provided on the pressing plate 33, and the installation avoidance notch 331 is used to avoid the bolts that fix the lock body 35 to the window clip body 21. The pressing plate 33 is also provided with a limiting protrusion 332, and the limiting protrusion 332 is used to abut the limiting column 361, thereby locking the window clip child lock 3. Figure 5 and Figure 6 It can be seen that the limiting protrusions 332 can be provided at the upper portion and the middle portion of the pressing plate 33 , so that the pressing plates 33 on both sides can abut against the limiting posts 361 .

[0057] The installation process of the window clip child lock 3 is as follows: after connecting the lock tongue 31 and the connecting plate 32, insert it into the window clip body 21 and push it to the position of the second sliding avoidance hole 23 opened on the window clip body 21; fix the knob 36 to the lock body 35 by bolts; insert the pressing plate 33 into the interior of the lock body 35; align the positioning column on the pressing plate 33 with the positioning hole 321, and fix the lock body 35 to the lock installation hole 25 opened on the window clip body 21 by bolts.
