[0027] Embodiment 1

[0028] This embodiment provides an invisible window screen locking device 100, as Figure 1-6 shown, provides an invisible window screen locking device, including a locking mechanism 1 installed at the end of the pulling beam of the invisible window screen to fix the pulling beam and the window frame, a traction mechanism 2 for pulling the locking mechanism 1 to open and close, and an opening and closing mechanism 3 for applying a pulling force to the traction mechanism 2. The locking mechanism 1 is fixedly connected to the traction mechanism 2, and the traction mechanism 2 is fixedly connected to the opening and closing mechanism 3. The locking mechanism 1 includes a locking frame 11 fixed at the end of the pulling beam, a lock tongue 12 arranged in the locking frame 11 and capable of reciprocating along the length direction of the pulling beam to open and close the locking mechanism 1, and a spring 13 sleeved on the lock tongue 12.

[0029] When the invisible screen window locking device is in the open state, the opening and closing mechanism 3 is in the closed state, no traction force is applied to the traction mechanism 2, and the lock tongue 12 of the locking mechanism 1 extends into the window frame under the elastic force of the spring 13, thereby fixing the invisible screen window; when the invisible screen window locking device is in the closed state, the opening and closing mechanism 3 is in the open state, and a traction force is applied to the traction mechanism 2, the spring 13 of the locking mechanism 1 is in a compressed state under the action of the traction force, and the lock tongue 12 withdraws from the window frame under the traction of the traction mechanism 2, thereby releasing the invisible screen window.

[0030] In order to improve the stability and operational flexibility of the locking mechanism 1 when opening and closing, the traction mechanism 2 is made of a non-rigid material, preferably a steel wire rope.

[0031] In order to further improve the aesthetics of the invisible screen locking device, the opening and closing mechanism 3 is made thinner and lighter. The opening and closing mechanism 3 includes a bottom shell 31 fixed to the middle area of the pull beam and a pull plate 32 rotatably connected to the bottom shell 31. When the opening and closing mechanism 3 is in a closed state, the plane where the pull plate 32 is located is in the same horizontal plane as the pull beam plane. Hook bodies 321 connected to the traction mechanism 2 are respectively provided at both ends of the pull plate 32. The traction of the traction mechanism 2 is achieved by opening and closing the pull plate 32, thereby achieving the opening and closing of the locking mechanism 1.

[0032] In order to further improve the stability of the lock tongue 12 entering the window frame, the end of the lock tongue 12 is arranged in an arc shape to ensure that the lock tongue 12 can smoothly enter and exit when it penetrates into the window frame.

[0033] When opening the pull plate 32, a certain pulling force needs to be applied. To facilitate the user to manually pry open the pull plate 32, the pull plate 32 is provided with a convex edge 322, which facilitates the user to pry open the pull plate 32 through the convex edge 322, thereby improving the user experience. The setting position of the convex edge 322 can be set as needed. In this embodiment, the convex edge 322 is preferably located in the middle area of the pull plate 32.

[0034] In order to further improve the stability of the locking frame 11 installed on the end of the tension beam, a fixing hole 111 for fixing the locking frame to the tension beam is provided on the locking frame 11. The locking frame 11 is fixed to the end of the tension beam by screws or bolts, which can effectively improve the firmness of the installation of the locking frame 11.

[0036] like Figure 6 As shown, the embodiment provides an invisible screen window 200, including a screen window main structure 201, a pull beam 202, a shutter box 203, and an invisible screen window locking device 100 installed on the pull beam. The specific structure and function of the invisible screen window locking device 100 are detailed in Example 1, and this embodiment will not be repeated.

[0037] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
