Description

Technical Field

[0001] The utility model relates to a screen window, in particular to a rolling screen window which can adapt to the shape of a window hole. Background Art

[0002] Glass windows are one of the main building facilities in modern buildings. They can increase daylighting and replace air. However, there are two states of glass windows in use. One is that the windows are tightly closed and airtight; the other is that they are fully open, which allows insects, mosquitoes and flies to enter the room and affect the environment. For this reason, it is necessary to install screens on the indoor side of the glass windows. However, most traditional screens are integrated structures, that is, the screen is directly fixed in the window frame, and the window frame is set on the glass window. This type of screen structure is relatively backward and has been gradually eliminated. The newly emerging roller screens have been widely used because they are easy to pull out.

[0003] The basic structure of a rolling screen is to install a grooved slide rail on the left and right sides of the window hole, install a reel with a coil spring on the top of the window hole and clamp the side of the screen, the screen is clamped by a rollable hard strip on both sides of the slide rail, the bottom of the screen is fixed on the handle, and the two ends of the crossbar are located in the groove of the slide rail. Then the screen is opened or closed by pulling the handle. Since the shape of the window hole cannot be a standard rectangle during construction, the shape of the window hole needs to be trimmed when installing the rolling screen, otherwise there may be gaps between the installed screen and the window hole, which need to be filled. However, both the correction and filling methods are cumbersome and require multiple constructions, which reduces the installation efficiency and aesthetics. Utility Model Content

[0004] In view of this, the utility model provides an adaptive rolling screen window, which can adapt to irregular window holes.

[0005] In order to solve the above technical problems, the technical solution of the utility model is to adopt an adaptive rolling screen window, including a winding box and a track assembly arranged at both ends of the winding box laterally and perpendicular to the winding box; a rotating shaft for rolling up the screen window body is arranged along its axial direction in the winding box; one end of the screen window body is fixed on the rotating shaft, and the other end extends out of the winding box and is connected to a handle; retractable filling blocks are arranged at both ends of the winding box, and a pre-tightening spring is installed between the filling block and the winding box; the track assembly includes a track body and a track base, the track body can float on the track base, and the angle between the track body and the track base can be adjusted.

[0006] As an improvement, the filling block is box-shaped, and the shape of its inner hollow is consistent with the shape of the end of the winding box; the filling block is buckled on the end of the winding box and can slide axially along the winding box; the preload spring is installed in the filling block.

[0007] As a further improvement, the rail base is consistent with the rail body in length, and an axial mounting groove is formed on the rail base, and the bottom of the rail body is embedded in the mounting groove.

[0008] As another further improvement, the rail base is formed by bending a plate, so that when the position and angle between the rail body and the rail base are adjusted, the rail body can be clamped by folding the side walls of the installation groove.

[0009] As an improvement, the handle comprises a handle body, a cushion block which can float on the handle body is arranged at the bottom of the handle body, and an angle between the cushion block and the handle body is adjustable.

[0010] As an improvement, a mounting groove is formed at the bottom of the handle body, and the cushion block is embedded in the mounting groove.

[0011] As an improvement, a soft brush is provided at the bottom of the pad.

[0012] As an improvement, the handle is rod-shaped, and locking components that can be matched and locked are provided on both ends of the handle and the track assembly.

[0013] As an improvement, the rotating shaft is provided with a coil spring and also includes a damper for offsetting the rebound force of the coil spring.

[0014] The utility model is beneficial in that:

[0015] The rolling screen window with the above structure is provided with filling blocks at both ends of the winding box, and the filling blocks are retractable and provided with pre-tightening springs. When there is a difference between the width dimension of the window hole and the winding box, certain adjustments can be made. In addition, the track body and the track base in the track assembly in this embodiment are floating, that is, the track body and the track base can make radial relative movements, so that a certain degree of adjustment can be made when the window hole size does not match. At the same time, the angle between the track body and the track base is adjustable, that is, the track body and the track base can be parallel or have a certain angle, so that when the window hole is an irregular rectangle, adaptive adjustments can be made. That is, it ensures a close fit with the window hole, and enables the track to be perpendicular to the winding box.

[0016] The utility model can adaptively adjust when the size of the window hole is different or irregular through the filling blocks at both ends of the winding box, the floating cooperation of the track body and the track base, and the floating cooperation of the handle and the cushion block, without the need to repair the window hole.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model provides an adaptive rolling screen window, comprising a winding box 1 and track components arranged at both ends of the winding box 1 and perpendicular to the winding box 1; a rotating shaft 8 for rolling up the screen window body 3 is arranged in the winding box 1 along its axial direction; one end of the screen window body 3 is fixed on the rotating shaft 8, and the other end extends out of the winding box 1 and is connected to a handle; in order to facilitate the automatic rebound of the screen window body 3, a coil spring is arranged on the rotating shaft 8. In order to avoid too fast rebound speed, a damper for offsetting the rebound force of the coil spring is also included.

[0024] Retractable filling blocks 2 are provided at both ends of the winding box 1, and a pre-tightening spring (not shown in the figure) is installed between the filling block 2 and the winding box; the track assembly includes a track body 4 and a track base 5, the track body 4 can float on the track base 5, and the angle between the track body 4 and the track base 5 can be adjusted.

[0025] In the utility model, filling blocks 2 are provided at both ends of the winding box 1, and the filling blocks 2 are retractable and provided with a pre-tightening spring. When the width of the window hole differs from that of the winding box, certain adjustments can be made. In addition, the track body 4 and the track base 5 in the track assembly in this embodiment are floating, that is, the track body 4 and the track base 5 can make radial relative movements, so that a certain degree of adjustment can be made when the window hole size does not match. At the same time, the angle between the track body 4 and the track base 5 is adjustable, that is, the track body 4 and the track base 5 can be parallel or have a certain angle, so that when the window hole is an irregular rectangle, adaptive adjustments can be made. That is, it ensures a close fit with the window hole, and enables the track to be perpendicular to the winding box.

[0026] Specifically, the filling block 2 is box-shaped, and its inner hollow shape is consistent with the shape of the end of the winding box 1; the filling block 2 is buckled at the end of the winding box 1 and can slide axially along the winding box 1; the preload spring is installed in the filling block. In this way, the filling block 2 will not occupy the internal space of the winding box 1, making the structure more compact.

[0027] like Figure 4 As shown, the track base 5 is consistent with the track body 4 in length, and an axial mounting groove is formed on the track base, and the bottom of the track body 4 is embedded in the mounting groove. In the utility model, the track base 5 and the track body 4 can float and adjust the angle by the above method, and the structure is simple and stable, and the manufacturing cost is low. Of course, other forms can also be selected, which are not limited in the utility model.

[0028] In this embodiment, the track base 5 is formed by bending a plate, so that when the position and angle between the track body 4 and the track base 5 are adjusted, the track body can be clamped by closing the side walls of the mounting groove. After adjusting the position and angle, the track body 4 and the track base 5 need to be tightened to prevent shaking. In this embodiment, since the track base 5 is formed by bending a plate, after positioning, it is only necessary to squeeze and close the two side walls of the track base 5 toward the middle to clamp and fix the track body 4, which is very convenient to use and does not require other components, thereby reducing costs.

[0029] The side opposite to the window hole and the winding box 1 may also be irregular, so the handle in the present invention includes a handle body 6, and a cushion block 7 that can float on the handle body 6 is provided at the bottom of the handle body 6, and the angle between the cushion block 7 and the handle body 6 is adjustable. When the cushion block 7 contacts the lower edge of the window hole, it can be adaptively adjusted according to the height and slope of the lower edge of the window hole, thereby closing the gap between the handle and the window hole.

[0030] Similar to the track mechanism structure, the handle body 6 has a mounting groove at the bottom, and the cushion block 7 is embedded in the mounting groove. However, the handle body 6 and the cushion block 7 do not need to be fastened, and a certain clearance is maintained so that the two can be flexibly connected.

[0031] In order to further facilitate filling the gap, a soft brush 9 is provided at the bottom of the cushion block 7 .

[0032] In addition, the handle is rod-shaped, and locking components that can be matched and locked are provided on both ends of the handle and the track assembly. When the screen window body 3 is pulled out, it is used to lock the handle position to prevent the screen window body 3 from rebounding under the action of the coil spring.

[0033] The utility model can adaptively adjust when the window hole size is different or irregular through the floating cooperation of the filling blocks 2 at both ends of the winding box 1, the track body 4 and the track base 5, and the floating cooperation of the handle body 6 and the cushion block 7, without the need to repair the window hole.

[0034] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
