Detailed ways

The following are specific embodiments of the present invention, and in conjunction with the accompanying drawings, further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

An assembled adjustable corner folding window, as shown in FIG. 1 , includes two parallel fixed frames 1 and several windows 2 arranged between the two fixed frames 1 .

During actual installation, the two fixing frames 1 are usually respectively fixed and installed on the upper and lower ends of the window hole by screws. For installing the window 2, the fixed slide rail 11 can be a closed groove structure at the bottom of the track, or a through-hole structure with an unclosed bottom of the track. In order to cooperate with the subsequent installation of other structures, this embodiment adopts a through-hole structure. The upper and lower ends of the form 2 are respectively provided with supporting shafts 21, the supporting shafts 21 are cylindrical, and the axial direction is perpendicular to the fixed frame 1. Fix in the slide rail 11 and get final product. In order to prevent the form 2 from falling off between the two fixed mounts 1, one end of the fulcrum 21 is connected to the form 2, and the other end passes through the fixed slide rail 11 of the through-hole structure to be provided with a stopper, the length and width of the stopper Both are greater than the width of the fixed slide rail 11. At this time, considering the thickness of the stop block, it is not suitable to be installed closely between the fixed frame 1 and the end of the window hole, and a gap should be left. Connected by expansion screws.

Since the support shaft 21 is cylindrical, in fact, after the support shaft 21 is inserted into the fixed slide rail 11, the support shaft 21 can directly rotate around its own central axis in the fixed slide rail 11, and can also slide along the fixed slide rail 11 at the same time. , so that the fulcrum 21 is rotatably and slidably disposed in the fixed slide rail 11 . But in order to improve the smoothness of rotation and sliding, a slider can be set in the fixed slide rail 11, the center of the slider is provided with a through hole, and the supporting shaft 21 is rotatably connected with the through hole through a rotating bearing. Under the action of the slider, the supporting shaft 21 can slide smoothly, thereby driving the window 2 to slide; under the action of the rotating bearing, the supporting shaft 21 can rotate smoothly, thereby driving the window 2 to rotate. Or the fulcrum 21 can be designed as a slider, and the fulcrum 21 is connected with the window 2 through a rotating bearing. In this embodiment, the former design method is adopted. Based on this, when the window 2 is turned to the plane where the plane coincides with the plane where the two fixing frames 1 are located, the window 2 is in the closed state; , which is the open state of window 2, and the open area is different depending on the included angle. After the windows 2 are rotated until the plane where they are located is perpendicular to the plane where the two fixing frames 1 are located, then all the windows 2 are slid and stacked together, which realizes the folding of several windows 2 .

It can be seen that the form 2 rotates around the axis where the fulcrum 21 is located. In the prior art, the fulcrum 21 is usually arranged above and below one side of the form 2. Under this structure, the form 2 rotates around the fulcrum. 21 When rotating, draw a circle with the entire width of the form 2 as the radius, and occupy a larger area. And in order to keep the balance of the window 2 rotation, the other side end of the window 2 will be hinged with the side end of the adjacent window, so that the two windows 2 cannot be opened. In this embodiment, the fulcrum 21 is arranged on the extension line of the central axis of the form 2, and when the form 2 rotates, it draws a circle with its half width as the radius, which reduces the position occupied by the form 2 when it rotates, and also ensures Therefore, the two adjacent windows 2 do not need to be hinged, and when the windows 2 are rotated to the plane where the plane coincides with the plane where the two fixed frames 1 are located, the sides of the two adjacent windows 2 are mutually It only needs to be abutted, and the two windows 2 can be opened to improve the flexibility of window opening.

Since there are many windows 2, it is necessary to push the windows 2 to slide and fold one by one during the folding operation. Therefore, in the present application, the folding structure 3 for controlling the sliding of the window 2 is also included.

As shown in Figure 2, the folding structure 3 includes a folding bar 31, and the folding bar 31 includes a plurality of connecting rods 311 connected in sequence, the end of the previous connecting rod 311 is rotationally connected with the end of the latter connecting rod 311, when two adjacent When the connecting rods 311 are rotated to be parallel to each other around the rotational connection between them, it can be considered that the two connecting rods 311 are folded together. There are many ways to rotate the two connecting rods 311. For example, as shown in FIG. 3 and FIG. The collar 311a of the connecting rod 311 is sheathed on a shaft body 312. In order to ensure that the two connecting rods 311 can rotate relative to each other, at least one of the collars 311a of the two collars 311a on the first shaft body 312 is rotatably connected to the shaft body 312. In this embodiment, the two collars 311a are rotatably connected to the shaft body 312 through rotating bearings. Since the follow-up connecting rod 311 needs to be connected with the window 2, for the flushness of the window 2, it is preferable to make the two connecting rods 311 flush, so the thickness of the collar 311a is preferably less than the thickness of the connecting rod 311, as shown in Figure 3, left The collar 311a of the connecting rod 311 is arranged on the upper part of its end, the collar 311a of the right connecting rod 311 is arranged on the lower part of its end, when the collar 311a of the two connecting rods 311 is set on the shaft body 312, The two connecting rods 311 are flush. Further, in order to protect the connecting part of the collar 311a and the shaft body 312, a sleeve 313 can also be provided outside the shaft body 312, and the side of the sleeve 313 is provided with an arc-shaped hole; between the connecting rod 311 and the collar 311a A limiting rod 311b is provided. One end of the limiting rod 311b is located outside the sleeve 313 and connected to the connecting rod 311, and the other end passes through the arc-shaped hole into the sleeve 313 and is connected to the collar 311a. When the connecting rod 311 rotates, the limiting rod 311b also rotates in the arc-shaped hole, and the rotation angle of the connecting rod 311 can be controlled by controlling the length of the arc-shaped hole.

As shown in Figure 2, when the folding bar 31 is installed with the form 2, the connecting rod 311 is firstly controlled to be perpendicular to the axial direction of the support shaft 21, and then several connecting rods 311 are respectively connected to the support shaft 21 at the lower end of the form 2, which can It may be a fixed connection or a rotational connection, but considering the fixed connection, the folding and rotation of the window 2 cannot be performed separately, so this embodiment adopts a rotational connection. In order to ensure stability, a connecting sleeve is generally provided at the center of the connecting rod 311, and the connecting sleeve and the support shaft 21 are rotatably connected through a rotating bearing. . At the same time, in order to improve the strength of the folding strips 31, two identical folding strips 31 can also be stacked up and down for use.

When folding, it is necessary to first turn some windows 2 to a certain angle between the plane where they are located and the plane where the two fixed frames 1 are located, so that several windows 2 can be stacked together, preferably rotated to the plane where they are located and the plane where the two fixed frames 1 are located. vertical. Then push the free end of a connecting rod 311 on the most side, such as as shown in Figure 2, push the right end of the rightmost connecting rod 311 to rotate counterclockwise, and the connecting rod 311 itself rotates counterclockwise around the fulcrum 21, so that the connection The left end of the rod 311 is shown to move rightward and outward in position, and correspondingly, the right end of the second connecting rod 311 connected to it should also move rightward and outward. In order to achieve this result, the second connecting rod 311 will move to the right along the fixed slide rail 11 as a whole, and at the same time rotate clockwise around the support shaft 21 to realize the right end of itself to move to the right and forward. Along with the movement of the second connecting rod 311, the window 2 connected thereon moves to the right and approaches the rightmost window 2. And the movement and rotation of the second connecting rod 311 will drive the next connecting rod 311 to move and rotate in the same way, and then realize the movement of all windows 2 . The distance between the two windows 2 is related to the angle between the two connecting rods 311. When the rightmost connecting rod 311 rotates counterclockwise to be perpendicular to the fixed frame 1, the second connecting rod 311 is also driven by it. Perpendicular to the fixing frame 1 , the two connecting rods 311 are attached together, so that the two windows 2 are stacked together, and the folding of the window 2 is completed.

Since the connecting rod 311 at the most side is also rotatably connected with the support shaft 21, and the fulcrum 21 is also rotatably connected with the slider in the fixed slide rail 11, when the connecting rod 311 is controlled to rotate, the fulcrum 21 is easy to rotate accordingly. , It is also easy to slide in the fixed slide rail 11, and it is difficult to apply a turning force. Therefore, the folding structure 3 also includes a folding control handle 32. As shown in FIG. Through the rotating connection of the rotating bearing, one end of the folding control handle 32 forms the folding connection end and is connected with the end of the most side connecting rod 311 of the folding bar 31. The specific structure of the rotating connection is connected with the rotating connection between the above two connecting rods 311. The structures are consistent, and the other end of the folding control handle 32 forms a folding control end. Since the first fixed shaft 12 is fixed, it is better to apply force when the folding control handle 32 is controlled to rotate around the first fixed shaft 12 . When the folding control end of the folding control handle 32 rotates clockwise, the folding connection end moves to the right and inward, thereby driving the connecting rod 311 on the side to move to the right and rotate counterclockwise, and then it is consistent with the above to complete Collapse operation. At the same time, in order to save effort, the folding control handle 32 includes a connection part that is rotatably connected with the first fixed shaft 12, a resistance part between the connection part and the folding connection end, and a power part between the connection part and the folding control end. In principle, the length of the power part is set to be greater than the length of the resistance part.

Because before folding, it is necessary to turn several windows 2 to a certain angle between the plane and the plane where the two fixing frames 1 are located. Rotational angle adjustment structure 4.

As shown in FIG. 5 , the angle adjusting structure 4 includes an adjusting frame 41 . The adjustment frame 41 is provided with an adjustment slide rail 411 parallel to the fixed slide rail 11. The adjustment slide rail 411 is provided with a plurality of connecting shafts 412 parallel to the support shaft 21. The connecting shafts 412 are rotatably and slidably arranged on the adjustment slide rail 411. Inside, similar to the support shaft 21, the cylindrical connecting shaft 412 can basically be rotatable and slidable directly, but in order to improve smoothness, a slider is also provided in the adjustment slide rail 411, and the connecting shaft 412 is connected to the slider The through holes on the upper are connected by rotating bearings. The number of connecting shafts 412 is consistent with the number of windows 2, and it is necessary to connect several connecting shafts 412 to the supporting shafts 21 at the lower ends of several windows 2 by connecting the swing arms 211, because the supporting shafts 21 and the connecting shafts 412 are already rotatable Therefore, the connecting swing arm 211 is fixedly connected to the support shaft 21 and the connecting shaft 412 . In this embodiment, since the stop block is just set on the support shaft 21, a part of the stop block is directly used as the connecting swing arm 211: after the lower end of the support shaft 21 passes through the fixed slide rail 11, it meets the stop block. The center point is connected, the end of the stop block is connected with the upper end of the connecting shaft 412 , and the part of the stop block between the end and the center point is the connecting swing arm 211 .

Since the length of the connecting swing arm 211 is fixed, if the adjusting frame 41 is moved to change the distance between the fixed slide rail 11 and the adjusting slide rail 411 in the horizontal direction, the supporting shaft 21 or the connecting shaft 412 must rotate so that The connecting swing arm 211 is adapted to this distance. Such as, at the beginning, the horizontal distance between the fixed slide rail 11 and the adjustment slide rail 411 was just consistent with the length of the connecting swing arm 211, and now the connecting swing arm 211 was perpendicular to the fixed slide rail 11; Adjust the horizontal distance between the rail 11 and the sliding rail 411. At this time, there is an angle between the connecting swing arm 211 and the fixed sliding rail 11, and the connecting swing arm 211 is fixedly connected with the support shaft 21. The connecting swing arm 211 Rotation will inevitably drive the fulcrum 21 to rotate. This embodiment utilizes this point to control the rotation of the support shaft 21 and then control the rotation of the window 2 . In addition, considering that when the window 2 rotates until the plane coincides with the plane where the two fixing brackets 1 are located, the horizontal distance between the fixed slide rail 11 and the adjustment slide rail 411 is zero, and the two are located on the same vertical plane, so in During installation, it is necessary to make the adjusting frame 41 and the fixing frame 1 not on the same level, and generally the adjusting frame 41 is arranged below the fixing frame 1 located below.

In order to facilitate the control of the movement of the adjustment frame 41, the angle adjustment structure 4 of the present embodiment also includes an angle control handle 42, the fixed frame 1 is provided with a second fixed shaft 13 parallel to the support shaft 21, and the middle part of the angle control handle 42 is provided with The connecting sleeve is rotatably connected with the second fixed shaft 13 through a rotating bearing. One end of the angle control handle 42 forms an adjustment connection end and is rotatably connected with the adjustment frame 41, and the other end forms an angle control end. In order to save effort, the angle control handle 42 also includes a connection part that is rotationally connected with the second fixed shaft 13, a power part between the connection part and the angle control end, and a resistance part between the connection part and the adjustment connection end. The length of the portion is greater than the length of the resistance portion. At the same time, an included angle of 75-105° is set between the power part and the resistance part, preferably 90°. In addition, in order to ensure the stability of the adjustment frame 41, as shown in FIG. 6, second fixed shafts 13 are usually provided at both ends of the fixed frame 1, and one end of the adjustment frame 41 is connected to a second fixed shaft through the above-mentioned angle control handle 42. The shaft 13 is connected, and the other end is connected with another second fixed shaft 13 through a connecting arm. One end of the connecting arm is rotatably connected with the adjusting frame 41 , and the other end is rotatably connected with the second fixed shaft 13 .

When in use, as shown in the top view of Figure 7, the control angle control handle 42 rotates a certain angle counterclockwise. The distance between the rails 11 decreases, and the fulcrum 21 cannot slide due to the limitation of the above-mentioned folding structure, so the connecting shaft 412 slides to the left, driving the connecting swing arm 211 to rotate clockwise, driving the fulcrum 21 to rotate clockwise, and then driving the window 2Turn clockwise to adjust the angle.

Based on the above structure, the installation method of the assembled adjustable corner folding window includes the following steps:

S1. Cut the two fixing frames 1 to the same length as the upper and lower ends of the window hole, and then connect the two fixing frames 1 to the upper and lower ends of the window hole respectively with screws, and at the same time control the gap between the fixing frame 1 and the upper end of the window hole for a stopper The slit that block inserts, leaves the slit that can be installed with stop block and angle adjustment structure 4 between control fixed mount 1 and the window hole lower end.

S2. Insert the supporting shaft 21 at the lower end of the window 2 into the central connecting sleeve of the connecting rod 311 of the folding bar 31 to form a whole.

Then insert a stop block in the gap between the fixed frame 1 and the end of the window hole, and fix the stop block with the end of the support shaft 21 passing through the fixed slide rail 11 .

S4. Insert the adjustment frame 41 between the fixed frame 1 and the lower end of the window hole, and install the angle control handle 42 on the second fixed shaft 13 of the fixed frame 1, and simultaneously connect the end of the stop block with the adjustment frame 41 The connecting shaft 412 is fixedly connected.
