Description
Technical Field
[0001] The present invention relates to the technical field of door and window structures, and particularly to a conversion device for increasing the sealing performance of casement and tilt-turn windows. Background Art
[0002] In the existing market, in the locked state of the casement and tilt-turn conversion device, the sealing performance of the upper hinge side window sash is poor, and problems such as air leakage and weak airtightness are likely to occur. Therefore, in order to change this casement and tilt-turn conversion device with poor sealing performance, a conversion device for increasing the sealing performance of casement and tilt-turn windows is designed. Summary of the Invention
[0003] Aiming at the deficiencies of the prior art, the present invention provides a conversion device for increasing the sealing performance of casement and tilt-turn windows, which can improve the airtightness of the window sash when the window sash is closed.
[0004] The present invention is realized by the following technical solutions: There is provided a conversion device for increasing the sealing performance of casement and tilt-turn windows, including a frame fixing plate connected to the frame groove, and a connecting rod connected to the window sash groove. A connecting plate and a rotating plate are also hinged between the connecting rod and the frame fixing plate. The bottom surface of the connecting rod is slidably connected with a sliding plate through a chute. One end of the sliding plate is connected with a connecting block, and the other end of the sliding plate is connected with a linkage through a pin. The upper end of the pin is eccentrically connected with a sliding head; the connecting plate includes a lower plate, an upper plate and a connecting inclined plate. One end of the lower plate close to the connecting inclined plate is provided with a horizontal chute for accommodating the sliding head. The connecting inclined plate is inclined from the upper plate to the lower plate, and an inclined chute communicating with the horizontal chute is provided on the connecting inclined plate. One end of the upper plate away from the connecting inclined plate is slidably hinged to the surface of the connecting rod, and the middle of the upper plate is hinged to the end of the connecting rod through a swing arm; the rotating plate is located below the frame fixing plate. One end of the rotating plate is slidably hinged to the frame fixing plate, and a blocking block that can abut and cooperate with the sliding head when the window is closed extends at this end. The other end of the rotating plate is hinged to the end of the lower plate of the connecting plate. The middle of the rotating plate is hinged with a connecting rod below the frame fixing plate. One end of the connecting rod is hinged to the lower plate, and the other end of the connecting rod is hinged to the bottom end of the frame fixing plate.
[0005] Further, the rotating plate includes a straight plate and a bent plate connected to one end of the straight plate and coplanar with the straight plate. The other end of the straight plate is bent upward twice to form a blocking plate parallel to the straight plate. The blocking block extends from the blocking plate. When the window is closed, the blocking block is located above one side in the length direction of the horizontal chute.
[0006] The rotating plate includes a straight plate, a bent plate and a blocking plate. After the blocking plate is bent, it can be used for abutting and cooperating with the anti-vibration piece on the connecting rod to improve the stability of the window sash. The blocking block extending from the blocking plate can limit the opening direction of the pin when the window sash is closed, which not only improves the stability when the window sash is closed, but also can improve the closing sealing performance.
[0007] Furthermore, an anti - sway piece is installed on the lower plate surface of the connecting plate through adjusting rivets at the end of the horizontal sliding groove. The anti - sway piece is arranged along the width direction of the lower plate, and one end of it is bent on one side in the length direction of the lower plate to form a bending part for limiting.
[0008] The anti - sway piece limits the upper edge of the window frame through the bending part. The position of the anti - sway piece can be adjusted by using the adjusting rivets, and it can be used to ensure the stability of the window sash when the window sash is closed.
[0009] Furthermore, a fixing piece riveted by screwing a tightening piece is rotatably installed on the upper surface of the frame fixing plate. A limiting block for restricting the fixing piece from rotating reversely in the initial position is arranged on the upper surface of the frame fixing plate on one side of the fixing piece.
[0010] The frame fixing plate is provided with a limiting block, so that when the fixing piece rotates, it can only rotate in one direction, which can prevent reverse rotation and prevent misoperation; when the fixing piece is in the initial position, the limiting block restricts the reverse rotation of the fixing piece, preventing misoperation and making it impossible to install the fixing piece.
[0011] Furthermore, a rubber washer is sleeved between the fixing piece and the frame fixing plate when screwing the tightening piece.
[0012] By using the rubber washer, the sealing performance of the connection part can be improved, and then the sealing performance when the window sash is closed can be improved.
[0013] Furthermore, a limiting groove is penetrated along the length direction in the middle of the frame fixing plate. One end of the rotating plate close to the blocking piece is vertically riveted with a limiting post located in the limiting groove and slidably connected with the limiting groove.
[0014] The limiting groove opened on the frame fixing plate is used to cooperate with the limiting post on the rotating plate, so as to ensure the smoothness when the window sash is opened and closed.
[0015] Furthermore, a polygonal hole groove that can be inserted and matched with a wrench is recessed on the surface of the sliding head.
[0016] The surface of the sliding head is recessed with a polygonal hole groove, which can be used to cooperate with the wrench. By using the wrench to rotate the sliding head, the position of the pin can be adjusted, and then the inner - outer distance of the window sash can be adjusted to adjust the sealing performance between the window sash and the window frame.
[0017] Furthermore, a receiving groove is recessed in the middle of the connecting rod, and an annular clamping spring is clamped in the receiving groove. The diameter of the annular end of the clamping spring close to the connecting plate is smaller than the diameter of the annular end of the clamping spring far from the connecting plate. The end of the connecting plate is sharpened and a fixing post extending into the clamping spring is riveted on the bottom surface of the tip.
[0018] The diameters of the two ends of the clamping spring are different. The end with the smaller diameter can clamp and limit the fixing column after the fixing column slides in, and then limit the window sash after it is opened, so that it can maintain a stable open state, improve the stability of the window sash, and play a role in stabilizing the opening angle of the window sash.
[0019] Furthermore, a fixing groove is formed on the surface of one end of the connecting rod, and a fixing block is installed in the fixing groove. The fixing block and the connecting rod are fixed in the window sash slot through an internal hexagon socket head cap screw. A relief groove for avoiding the vertical internal hexagon socket head cap screw is correspondingly opened on the sliding plate.
[0020] The connecting rod is fixed in the window sash slot as a whole through the fixing block in the fixing groove and the vertical internal hexagon socket head cap screw, which can be used for positioning and installing the connecting rod.
[0021] Furthermore, the connecting rod includes a V-shaped rod and a swing rod. One end of the V-shaped rod is hinged to one end of the swing rod, the other end of the V-shaped rod is hinged to the frame fixing plate, and the V-shaped rod is hinged to the lower rotating plate near the hinge point with the frame fixing plate.
[0022] The beneficial effects of the present invention: In the present invention, the rotating plate is arranged on the connecting plate. The rotating plate is provided with a blocking block. The connecting plate is provided with a horizontal sliding groove and an inclined sliding groove. The pin can slide in the sliding groove on the connecting plate to realize the opening, locking and suspension opening of the window sash. When the sliding head of the pin is in the locking position in the sliding groove on the connecting plate, the blocking block on the rotating plate presents a blocking function, that is, when the pin is in the locking position, the blocking block and the horizontal sliding groove together limit the movement of the pin, so that when the window sash is closed, the window is not easily opened by external force, and thus its sealing performance is improved, and the sealing and airtightness of the window sash in the outdoor and indoor directions are enhanced.
