[0049] Please refer to the following: Figures 1 to 8 The window screen rewinding structure 10 provided in the embodiments of this application will now be described. The window screen rewinding structure 10 includes: a frame 11, a window screen 12, and a balance bar 13.

[0050] A winding actuator 15 is installed on the top of the frame 11, and the top of the window screen 12 is connected to the winding actuator 15. The winding actuator 15 can drive the window screen to unfold or rewind. A balance bar 13 is installed at the bottom of the window screen 12. Guide rail profiles 14 are provided on the left and right sides of the frame 11. A guide groove 141 is provided on the opposite side of the guide rail profile 14. Both ends of the balance bar 13 are equipped with guide sliding parts 131 for sliding installation in the guide groove 141. A first limiting groove 142 is provided on the front or rear side of the guide groove 141. Both ends of the window screen 12 are provided with a first T-shaped strip 121, which is restricted in the first limiting groove 142.

[0051] Specifically, by setting a guide groove 141 and a first limiting groove 142 on the front or rear side of the guide groove 141, on the one hand, the first limiting groove 142 allows the first T-shaped strip 121 of the window screen to be inserted, which not only avoids the problem of the window screen coming off the window frame, but also prevents the window screen from getting stuck during unfolding; effectively improving the mosquito-proof effect and the reliability of the window screen's opening and closing; on the other hand, the guide groove 141 allows the guide sliding member 131 to be movably installed, which can further improve the smoothness of the window screen when rolling up and reduce the occurrence of the window screen getting stuck during the rolling up process.

[0052] In some embodiments of this application, the first limiting groove 142 is provided on the front side of the guide slide groove 141; the first T-shaped strip 121 includes a limiting part 1211 and a connecting part connected to the limiting part 1211, the limiting part 1211 is slidably restricted in the first limiting groove 142, and the connecting part is connected to the window screen 12.

[0053] Specifically, the connecting part includes a vertical connecting section 1212 and a horizontal connecting section 1213; one end of the vertical connecting section 1212 is connected to the limiting section 1211, and the other end is connected to the horizontal connecting section 1213, so that the limiting section 1211 and the horizontal connecting section 1213 are arranged parallel to each other; the other end of the horizontal connecting section 1213 is connected to the window screen 12. With this structure, the limiting section 1211 can slide and be restricted in the first limiting groove 142, eliminating the need for auxiliary parts such as magnets to fix and seal the window screen, which can improve the mosquito-proof effect of the window screen, and at the same time prevent it from detaching from the window frame due to strong winds.

[0054] In some other embodiments of this application, the guide slide member 131 includes a mounting base 1311 and a slide seat 1312 disposed on the mounting base 1311 facing the guide rail profile 14. The slide seat 1312 is slidably mounted in the guide groove 141.

[0055] Specifically, the sliding seat 1312 has a first clamping plate 1313 on one side facing the first limiting groove 142. The first clamping plate 1313 can clamp the connecting part with the sliding seat 1312 and make the limiting part 1211 located in front of the first clamping plate 1313.

[0056] Preferably, the sliding seat 1312 has a first recess 1317 on one side facing the first limiting groove 142, and the first clamping plate 1313 can be detachably installed in the first recess 1317 by screws. When the lower end of the first T-shaped strip 121 is assembled with the guide sliding member 131, the horizontal connecting section 1213 is clamped by the first clamping plate 1313 and the first recess 1317, and the vertical connecting section extends forward, so that the limiting part 1211 and the horizontal connecting section 1213 are arranged parallel to each other. At this time, the limiting part 1211 can abut against the first clamping plate 1313.

[0057] More specifically, a second clamping plate 1314 is detachably mounted on the front side of the first clamping plate 1313 via screws. The second clamping plate 1314, together with the first clamping plate 1313, clamps the limiting part 1211. At this point, the lower end guide sliding member 131 of the first T-shaped strip 121 can be assembled. Since the limiting part 1211 and the horizontal connecting section 1213 are arranged parallel to each other, the limiting part 1211 is also arranged parallel to the window screen. This structure can further improve the smoothness of the window screen winding mechanism 15.

[0058] In other embodiments of this application, a second limiting groove 143 is provided on the rear side of the guide groove 141; a limiting rib 1315 is provided on the side of the sliding seat 1312 facing the second limiting groove 143, and the limiting rib 1315 is movable and restricted within the second limiting groove 143. This structure allows the sliding displacement seat to smoothly and reliably insert into the guide groove 141 during the unfolding of the window screen, thereby improving the reliability of the window screen winding structure 10.

[0059] Specifically, the balance bar 13 has a hollow insertion chamber 132, and the mounting base 1311 has an insertion protrusion 1316 on the side opposite to the sliding base 1312 that can be inserted into the insertion chamber 132. The balance bar 13 has a third limiting groove 133 on its front side, and the bottom of the window screen 12 has a second T-shaped strip 122. The second T-shaped strip 122 is inserted into the third limiting groove 133, thereby completing the connection between the bottom of the window screen and the balance bar 13.

[0060] It should be noted that the structure of the second T-shaped strip 122 is the same as that of the first T-shaped strip 121. Furthermore, the T-shaped strip structure is also suitable for the connection between the window screen and the winding actuator 15.

[0061] More specifically, the frame 11 includes an upper profile 111, a lower profile 112 spaced vertically from the upper profile 111, a left profile 113 connected to the left ends of the upper profile 111 and the lower profile 112, and a right profile 114 connected to the right ends of the upper profile 111 and the lower profile 112. The upper profile 111, the lower profile 112, the left profile 113, and the right profile 114 form an opening. A winding actuator 15 is installed on the upper profile 111. The winding actuator 15 can drive the window screen 12 to unfold and cover the opening. The guide rail profiles 14 are installed one by one corresponding to the left profile 113 and the right profile 114.

[0062] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
