Referring to fig. 1 and 2, fig. 1 shows a schematic structural diagram of a wind brace 100 in some embodiments of the present application, fig. 2 shows an exploded schematic diagram of the wind brace 100 in some embodiments of the present application, and the wind brace 100 may be used in a window and door system (not shown) to limit a sash portion and a frame portion of the window and door system, so as to prevent the sash portion from swinging due to wind. Specifically, the wind brace 100 includes a connecting rod 110, a sliding rail 120, and an adjustment assembly 130. The connecting rod 110 has a body 111 and a connecting portion 112, the connecting portion 112 is mounted on a sash of the window and door system, one end of the body 111 is rotatably connected to the adjusting assembly 130, and the other end is rotatably connected to the connecting portion 112. The connection method between the main body 111 and the adjustment unit 130 and between the main body 111 and the connection portion 112 is not limited, and any suitable rotational connection method such as hinge connection and caulking may be used. The slide rail 120 is mounted on the frame portion, and includes two opposite side walls 121 and a bottom wall 124 connected to the two side walls 121, and the bottom wall 124 and the two side walls 121 enclose to form an opening/closing groove 125. The adjusting assembly 130 is slidably disposed in the opening and closing groove 125.

It can be understood that, during the opening or closing process of the door and window system, the rotation of the sector portion relative to the frame portion will drive the body portion 111 to rotate relative to the adjusting assembly 130, and at the same time, push the adjusting assembly 130 to slide in the opening and closing slot 125. Therefore, the opening and closing force of the door and window system can be changed by changing the magnitude of the frictional force between the adjusting assembly 130 and the slide rail 120, and the sash and the frame can be fixed by fixing the adjusting assembly 130 and the slide rail 120 to each other, so that the sash and the frame are limited.

Further, as shown in fig. 3 and 4, the sliding assembly includes a sliding block 131, an adjusting block 150, an adjusting structure 160, and a friction member 170. The slider 131 includes a rotating portion 137 and an adjusting portion 138, the connecting rod 110 is rotatably connected to the rotating portion 137, and the adjusting block 150 and the adjusting structure 160 are accommodated in the adjusting portion 138. Specifically, the axial direction of the slider 131 is parallel to the sliding direction of the slider 131 in the opening and closing groove 125, the slider 131 includes two opposite side surfaces 132, and the two side surfaces 132 are respectively opposite to the side walls 121 of the slide rail 120. The sliding block 131 is internally provided with a sliding groove 134 and a connecting groove 136, the sliding groove 134 extends along the axial direction of the sliding block 131, and the connecting groove 136 is communicated with the sliding groove 134 and penetrates through the side surface 132. The adjusting block 150 is slidably disposed in the sliding groove 134, and an axial direction of the adjusting block 150 is parallel to a sliding direction of the adjusting block 150 in the sliding groove 134, at this time, the axial direction of the adjusting block 150 is parallel to the axial direction of the sliding block 131. The friction member 170 is located in the connecting groove 136, and partially enters the sliding groove 134 and abuts against the adjusting block 150, and another part of the friction member 170 protrudes from the sliding block 131 at the side surface 132 and abuts against the side wall 121 of the sliding rail 120. The adjustment structure 160 is located in the sliding slot 134 and on a side of the adjustment block 150 facing away from the friction member 170. The adjusting structure 160 includes an adjusting element 161, a fitting element 164 and an elastic element 166, and as shown in fig. 3, the adjusting element 161, the fitting element 164 and the elastic element 166 are sequentially arranged in the axial direction of the adjusting block 150. The adjusting member 161 is fixed relative to the adjusting block 150 in the axial direction of the adjusting block 150, one end of the fitting member 164 is fixedly connected to the adjusting member 161, the other end abuts against one end of the elastic member 166, and the other end of the elastic member 166 abuts against the adjusting block 150. And the adjusting element 161 partially overlaps the fitting element 164, and the overlapping portion of the adjusting element 161 and the fitting element 164 is adjustable in size in the axial direction of the adjusting block 150, that is, the adjusting element 161 and the fitting element 164 are integrally adjustable in size in the axial direction of the adjusting block 150.

In the adjusting assembly 130, the space in the sliding groove 134 is limited in the axial direction of the adjusting block 150, and the adjusting member 161 and the engaging member 164 are adjustable in the axial direction of the adjusting block 150. By changing the dimension of the adjusting block 150 and the engaging member 164 in the axial direction of the adjusting block 150, the dimension of the elastic member 166 in the axial direction of the adjusting block 150 can be changed, that is, the compression amount of the elastic member 166 can be changed, and the magnitude of the elastic force applied by the elastic member 166 to the adjusting block 150 can be changed. Therefore, the acting force of the adjusting block 150 on the friction member 170 can be changed, and when the part of the friction member 170, which protrudes out of the sliding block 131, is in contact with the rest of the object, the friction force between the friction member 170 and the object can be changed.

For example, when the adjusting assembly 130 is used in the wind brace 100, the part of the friction member 170 protruding from the sliding block 131 abuts against the side wall 121 of the sliding rail 120, and the magnitude of the friction force between the friction member 170 and the side wall 121 when the sliding block 131 slides relative to the sliding rail 120 can be changed by changing the magnitude of the acting force applied to the friction member 170 by the adjusting block 150. Therefore, when the wind brace 100 is applied to a door and window system, the effect of adjusting the opening and closing force of the door and window system can be achieved by changing the friction force between the friction piece 170 and the side wall 121, so that the opening and closing force of the door and window system can be adjusted according to different wind powers or different user strength differences, and the wind brace 100 can be suitable for different use scenes.

Also, in the embodiment shown in fig. 1 and 3, there are two connecting grooves 136, there are two friction members 170, the friction members 170 correspond to the connecting grooves 136 one by one, and the adjusting block 150 includes two abutting surfaces 151, and the two abutting surfaces 151 are connected to each other and are both inclined to the axial direction of the adjusting block 150. One of the coupling grooves 136 penetrates the corresponding one of the side surfaces 132, the first abutment surface 151 is disposed toward the corresponding one of the coupling grooves 136, and one of the friction members 170 abuts the corresponding one of the abutment surfaces 151 and is located inside the corresponding one of the coupling grooves 136. Further, in some embodiments, the adjusting block 150 has a bottom surface 152, the bottom surface 152 is disposed toward the bottom wall 124 of the slide rail 120, and in a cross section of the adjusting block 150 parallel to the bottom surface 152, line segments formed by the two abutting surfaces 151 are distributed in an axisymmetric manner with respect to an axis of the adjusting block 150. By providing the abutting surface 151 inclined to the axial direction of the adjusting block 150, the adjusting block 150 is facilitated to apply a force to the friction member 170, which is directed to the side wall 121 in a direction perpendicular to the side surface 132, so as to adjust the friction force between the friction member 170 and the side wall 121 better. Of course, in other embodiments, the sliding block 131 may be provided with only one adjusting slot 153, and correspondingly, one friction member 170 is provided, and the friction member 170 protrudes from the sliding block 131 at one of the side surfaces 132 of the sliding block 131 and abuts against one of the side walls 121 of the sliding rail 120. And set up two friction pieces 170 and respectively with two lateral walls 121 butt, can adjust the frictional force between two friction pieces 170 and two lateral walls 121 simultaneously, be more favorable to adjusting the power of opening and close of door and window system.

In addition, with continued reference to fig. 1 and 3, in some embodiments, the adjusting member 161 is a screw and includes a nut portion 162 and a screw portion 163, and the fitting member 164 is a ring nut, the fitting member 164 includes an inner side 132 and an outer side 132 disposed opposite to each other, the inner side 132 is provided with an internal thread, and the fitting member 164 is threadedly coupled to the screw portion 163. Thus, when the adjusting member 161 is rotated relative to the engaging member 164, the adjusting member 161 can move toward or away from the engaging member 164 due to the threaded engagement between the adjusting member 161 and the engaging member 164. Specifically, the elastic member 166 may be a spring, the engaging member 164 abuts against the elastic member 166, and in the embodiment shown in fig. 3, when the adjusting member 161 is tightened, the adjusting member 161 moves toward the engaging member 164, the size of the connecting portion 112 between the adjusting member 161 and the engaging member 164 increases, that is, the size of the adjusting member 161 and the engaging member 164 in the axial direction of the adjusting block 150 decreases, the size of the elastic member 166 in the axial direction of the adjusting block 150 increases, the compression amount of the elastic member 166 decreases, the elastic force applied to the adjusting block 150 by the elastic member 166 decreases, and thus the friction force between the friction member 170 and the sidewall 121 decreases. Similarly, when the adjusting member 161 is unscrewed, the connecting portion 112 between the adjusting member 161 and the fitting member 164 is reduced in size, the compression amount of the elastic member 166 is increased, and the frictional force between the friction member 170 and the side wall 121 is increased.

Therefore, by arranging the adjusting structure 160, the friction force between the friction member 170 and the side wall 121 can be adjusted only by screwing the adjusting member 161 with respect to the fitting member 164, so as to adjust the opening and closing force of the door and window system, and the operation of adjusting the opening and closing force of the door and window system is convenient. Of course, in other embodiments, the elastic member 166 may be an elastic substance such as elastic rubber or cotton pad, as long as the elastic member 166 can apply an elastic force to the adjusting block 150 and has a certain amount of compression in the axial direction of the adjusting block 150. For example, in other embodiments, the adjusting element 161 is connected with the engaging element 164 in a snap-fit manner, and a plurality of detents are provided between the adjusting element 161 and the engaging element 164, and when the detents are different, the size of the snap-fit portion between the adjusting element 161 and the engaging element 164 is different, so that by making the adjusting element 161 and the engaging element 164 in different detents, the size of the adjusting element 161 and the engaging element 164 in the axial direction of the adjusting block 150 can be changed, and the compression amount of the elastic element 166 can be adjusted.

Further, in some embodiments, the adjusting block 150 is provided with an adjusting groove 153 extending along the axial direction of the adjusting block 150, the engaging element 164 and the elastic element 166 are located in the adjusting groove 153, the elastic element 166 abuts against the groove bottom of the adjusting groove 153 to apply elastic force to the adjusting block 150, and the adjusting element 161 is partially located in the adjusting groove 153 and connected with the engaging element 164. Through setting up adjustment tank 153, can carry on spacingly to adjusting structure 160, reduce simultaneously and adjust structure 160 and adjust the whole ascending size in the regulating block 150 axial of regulating block 150, be favorable to reducing the size of adjusting part 130. Of course, in other embodiments, the adjustment slot 153 may not be disposed in the adjustment block 150, the adjustment structure 160 is disposed on one side of the adjustment block 150, and the elastic member 166 directly abuts against one side of the adjustment block 150.

Further, referring to fig. 5 and 6 together, in order to prevent the adjusting member 161 from rotating synchronously with the engaging member 164 when the adjusting member 161 is screwed, which may cause the threads of the adjusting member 161 and the engaging member 164 to be difficult to engage, in some embodiments, the adjusting block 150 further has a guide groove 154 penetrating through the bottom surface 152, and the guide groove 154 extends along the axial direction of the adjusting block 150 and communicates with the adjusting groove 153. And the outer side 132 of the fitting member 164 is extended to form a guide block 165, and the guide block 165 is slidably disposed in the guide groove 154. Therefore, the guide block 165 can limit the circumference of the fitting piece 164, and when the adjusting piece 161 is screwed, the fitting piece 164 is not driven to rotate, so that the threads of the adjusting piece 161 and the fitting piece 164 can be better matched. Moreover, when the size of the engaging portion of the adjusting element 161 and the engaging element 164 changes, and the engaging element 164 slides in the adjusting groove 153, the guiding block 168 can slide along the guiding groove 154 to limit the engaging element 164, so that the engaging element 164 is not easy to shift circumferentially.

Referring to fig. 3 and 4 together, in some embodiments, the sliding block 131 further includes an end surface 139 connecting the two side surfaces 132, the end surface 139 is perpendicular to the axial direction of the adjusting block 150, the sliding block 131 is opened with an operation hole 140 penetrating the end surface 139, and the operation hole 140 is communicated with the sliding groove 134 and is disposed opposite to the nut portion 162. Therefore, when the adjusting member 161 needs to be screwed, a tool such as a screwdriver (not shown) is only required to extend into the sliding groove 134 from the operation hole 140 to reach the nut portion 162, and the adjusting member 161 can be rotated by the engagement of the screwdriver and the nut portion 162, so that the rotating operation of the adjusting member 161 is facilitated. It will be appreciated that the adjustment member 161 may be a cross screw or socket head cap screw, and correspondingly, the screwdriver may be a cross screwdriver or socket head cap screw.

Also, in some embodiments, the inner wall surface of the sliding groove 134 extends to form a limiting block 135, the limiting block 135 is disposed around the screw portion 163, and the screw cap portion 162 is located on a side of the limiting block 135 away from the fitting piece 164 and is grounded to the limiting block 135. The stopper 135 is formed with an end of the slider 131 to define a space for limiting the nut 162. Therefore, when the size of the whole of the adjusting member 161 and the engaging member 164 is changed, the adjusting member 161 does not separate from the limiting space due to the limiting function of the limiting space, and the engaging member 164 can move toward the direction approaching or separating from the adjusting member 161, thereby changing the compression amount of the engaging member 164 on the elastic member 166. For example, when the adjustment element 161 and the engagement element 164 are integrally reduced in size in the axial direction of the adjustment block 150, the engagement element 164 moves toward the direction close to the limit block 135, that is, the engagement element 164 moves away from the elastic element 166, so as to release the elastic element 166, the compression amount of the elastic element 166 is reduced, and the elastic force applied to the adjustment block 150 by the elastic element 166 is reduced. Similarly, when the adjustment element 161 and the engaging element 164 are integrally increased in size in the axial direction of the adjustment block 150, the engaging element 164 compresses the elastic element 166, so that the elastic force applied by the elastic element 166 to the adjustment block 150 is increased. It is understood that in other embodiments, the limit block 135 may be disposed only around a portion of the screw portion 163, or disposed on two opposite sides of the screw portion 163, as long as the limit block 135 can limit the nut portion 162 in the limit space.

In addition, referring to fig. 1 and 3, in some embodiments, the slider 131 includes a bottom wall surface 133 connecting the side surface 132 and the end surface 139, the bottom wall surface 133 is disposed toward the bottom wall 124, and the sliding groove 134 penetrates the bottom wall surface 133. Therefore, when the sliding block 131 is separated from the sliding rail 120, the adjusting block 150 and the adjusting structure 160 can be separated from the bottom wall surface 133 or enter the sliding groove 134, the adjusting assembly 130 is more convenient to mount, and when the sliding block 131 is slidably arranged in the sliding rail 120, the bottom wall surface 133 is abutted against the bottom wall 124, the adjusting block 150 and the adjusting structure 160 in the sliding groove 134 are limited, and the adjusting block 150 and the adjusting structure 160 cannot be separated from the sliding groove 134. Also, in some embodiments, the friction member 170 is substantially cylindrical in shape and the radial dimension of the connecting slot 136 is greater than the radial dimension of the friction member 170, i.e., the friction member 170 can enter or exit the connecting slot 136 from the side 132, which facilitates the installation of the friction member 170. When the sliding block 131 is slidably disposed in the sliding rail 120, the side surface 132 is opposite to the side wall 121, the friction member 170 abuts against the side wall 121, and the side surface 132 and the side wall 121 limit the friction member 170 together, so that the friction member 170 cannot be separated from the connecting groove 136.

Further, referring to fig. 2, in some embodiments, a portion of the side wall 121 away from the bottom wall 124 is bent toward the opening and closing groove 125 to form a friction portion 122, the friction portion 122 extends along the opening and closing groove 125, sliding portions 141 extend from two sides of the slider 131, when the slider 131 slides in the opening and closing groove 125, the sliding portions 141 are located in a sliding space between the friction portion 122 and the bottom wall 124, and the friction portion 122 can limit the sliding portions 141, so that the slider 131 is not easily separated from the opening and closing groove 125. Also, in some embodiments, the friction portion 122 is partially recessed to form a detent 123. Referring to fig. 7, when the sliding block 131 slides in the opening and closing groove 125, the friction member 170 contacts the friction portion 122, when the sliding block 131 slides to a position where the friction member 170 is opposite to the positioning groove 123, the friction member 170 is embedded into the positioning groove 123 due to the elastic force of the elastic member 166, and the sliding block 131 cannot slide in the opening and closing groove 125 any more, thereby realizing the positioning between the frame and the sash of the door and window system. Through setting up constant head tank 123, need not be with the help of other works, also need not to operate other spare parts and can realize the location of frame and sector promptly, make door and window system's spacing operation more convenient.

It can be understood that, when it is required to enable the sliding block 131 to continuously slide in the opening and closing slot 125, only the friction member 170 is pressed toward the connecting slot 136, so that the elastic member 166 is compressed, the friction member 170 is separated from the positioning slot 123, and the sliding block 131 can continuously slide in the opening and closing slot 125. In some embodiments, the positioning grooves 123 may be disposed in multiple numbers, and the positioning grooves 123 are sequentially arranged along the axial direction of the slider 131, so that multiple positioning states are provided between the slider 131 and the slide rail 120, and the frame and the sash of the door and window system can be fixed to each other at more angles.

In addition, in some embodiments, the wind brace 100 further includes a reinforcing pad 180, a projection of the reinforcing pad 180 on the bottom wall 124 coincides with a projection of the rotating portion 137 on the bottom wall 124, the reinforcing pad 180 is disposed on the rotating portion 137, and the connecting rod 110 is rotatably connected to the rotating portion 137 and the reinforcing pad 180. The reinforcing washer 180 may be made of a metal material such as steel, and is used to reinforce the rotating portion 137, so that the rotating connection between the adjusting assembly 130 and the connecting rod 110 is more secure.
