[0025] Reference Figures 1-4 A door and window with a protection structure, comprising: a window body 2 and a control box 3, the window body 2 is arranged on the inner side of the wall body 1, the window body 2 adopts a front and rear opening and closing design, that is, a traditional casement window, and the control box 3 is fixedly installed on the surface of the wall body 1, and the control box 3 is located on the indoor side.
[0026] Specifically, as shown in Figure 2 , the front end of the window body 2 is integrally connected with a pull rod 4, and limiting slots 5 are formed through the upper and lower ends of the pull rod 4.
[0027] Specifically, as shown in Figure 3 , a telescopic rod 6 is arranged at the upper end of the control box 3, and springs 7 are connected to the two sides of the upper end of the control box 3.
[0028] Further, the telescopic rod 6 is designed in two sections, i.e. a fixed part and a movable part, and the movable part can be telescoped in the inner cavity of the fixed part.
[0029] Moreover, the movable part of the telescopic rod 6 and the upper part of the spring 7 are connected with the pull plate 8, and the bottom side of the pull plate 8 is integrally connected with the limiting insertion rod 9.
[0030] In this embodiment, during the closing process of the window body 2, the pull plate 8 needs to be pulled upwards first, at this time, the two springs 7 are stretched, and the limiting insertion rod 9 is pulled upwards, when the window body 2 is completely closed, the pull plate 8 is released, and the limiting insertion rod 9 moves downwards under the rebounding action of the two springs 7 and is inserted into the limiting insertion slot 5 from above.
[0031] Therefore, when the window body 2 is closed, the locking of the window body 2 can be completed synchronously.
[0032] Specifically, as shown in the figure, the control box 3 is provided with a fixed ear 10 on both sides, and the fixed ear 10 is fixed on the surface of the wall body 1 through a bolt. Figure 3
[0033] Specifically, as shown in the figure, the control box 3 is provided with a fixed ear 10 on both sides, and the fixed ear 10 is fixed on the surface of the wall body 1 through a bolt. Figure 4
[0034] Meanwhile, the top rod 18 is integrally connected to the bottom of the screw rod seat 17 on both sides, and the two top rods 18 pass through the control box 3 and are connected to the push plate 13, and the limiting insertion rod 14 is connected to the upper side of the push plate 13.
[0035] In this embodiment, the operation of the servo motor 15 is started to drive the screw rod 16 to rotate, and then the screw rod seat 17 connected with the screw rod 16 outside is moved vertically and linearly in the control box 3, and the top rod 18, the push plate 13 and the limiting insertion rod 14 are moved synchronously.
[0036] Therefore, when the window body 2 is closed, the operation of the push assembly is started to insert the limiting insertion rod 14 into the limiting insertion slot 5 from below, and then the secondary locking of the window body 2 is completed.
[0037] Correspondingly, as shown in the figure, the infrared receiver 11 and the case 12 are connected to the front end of the control box 3, the infrared receiver 11 is used to receive the signal emitted by the external infrared remote control, and the case 12 is built-in with a power module and a PLC control end. Figure 3
[0038] Therefore, when the infrared receiver 11 receives the signal of the external infrared remote control, the infrared receiver 11 transmits the signal to the PLC control end, and the PLC control end will automatically start the operation of the pushing assembly, and perform the locking operation, so that the pushing assembly can be used as a child lock, and the use safety is improved.
[0039] Working principle: in the use process, the operation of the pushing assembly in the control box 3 is started through the external infrared remote control, the pushing assembly drives the limiting insertion rod two 14 to move upward and insert into the limiting insertion slot 5 at the bottom of the pull rod 4, so that the window body 2 is locked in the closed state, and compared with the traditional manual closing mode, the locking mode can be used as a child lock, the safety protection performance is improved, when the safety lock is not needed, the limiting insertion rod one 9 can be inserted into the limiting insertion slot 5 above the pull rod 4 through the rebounding action of the spring 7, so as to complete the manual locking of the window body 2, compared with the traditional rotary handle, as long as the window body 2 is in the closed state, the limiting insertion rod one 9 will lock the window body 2 under the rebounding action of the spring 7, while the traditional rotary handle is easy to forget to lock after being closed, and the window body 2 can be directly pushed away, the design can further improve the use safety.
[0040] The above is only the preferred specific implementation mode of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the application concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
