Description

A switching device for casement and overhang openings to improve sealing performance Technical Field

[0001] This utility model relates to the field of door and window structure technology, specifically to a conversion device for casement and overhang openings that increases sealing performance. Background Technology

[0002] In the existing market, the casement and overhang conversion devices have poor sealing performance on the upper hinge side window sash when locked, which is prone to problems such as air leakage and weak air tightness. Therefore, in order to change this casement and overhang conversion device with poor sealing performance, a casement and overhang conversion device with improved sealing performance is designed. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, this utility model provides a switching device for casement and overhang windows to increase the airtightness of the window sash when it is closed.

[0004] This utility model is achieved through the following technical solution:

[0005] A switching device for casement and overhang windows with improved sealing is provided. It includes a frame fixing plate connected to a window frame groove and a connecting rod connected to a window sash groove. A connecting plate and a rotating plate are hinged between the connecting rod and the frame fixing plate. A sliding plate is slidably connected to the bottom surface of the connecting rod via a groove. One end of the sliding plate is connected to a connecting block, and the other end is connected to a linkage via a pin. A sliding head is eccentrically connected to the upper end of the pin. The connecting plate includes a lower plate, an upper plate, and a connecting inclined plate. A transverse groove for accommodating the sliding head is provided at the end of the lower plate near the connecting inclined plate. The connecting inclined plate slopes from the upper plate to the lower plate. The upper plate is provided with a sloping groove that communicates with the horizontal sliding groove. The end of the upper plate away from the connecting sloping plate is slidably hinged to the surface of the connecting rod. The middle part 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. A stop block extends from this end of the rotating plate and can abut against the sliding head when the window is closed. The other end of the rotating plate is hinged to the end of the lower plate of the connecting plate. A connecting rod is hinged to the middle part of the rotating plate 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.

[0006] Furthermore, the rotating plate includes a straight plate and a curved 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 stop plate parallel to the straight plate. A stop block extends from the stop plate and is formed when the window is closed. The stop block is located above one side of the horizontal sliding groove in the length direction.

[0007] The rotating plate includes a straight plate, a curved plate, and a stop plate. The stop plate, after being bent, can be used to engage with the anti-sway plate on the connecting rod to improve the stability of the window sash. The stop block extending from the stop plate can limit the opening direction of the pin when the window sash is closed, which not only improves the stability of the window sash when it is closed, but also improves the sealing performance when closed.

[0008] Furthermore, an anti-sway plate located at the end of the transverse slide groove is installed on the lower plate surface of the connecting plate by adjusting rivets. The anti-sway plate is set along the width direction of the lower plate, and one end of it is bent on one side of the length direction of the lower plate to form a bending part for limiting the position.

[0009] The anti-sway plate limits the upper edge of the window frame through the bending part, and the position of the anti-sway plate can be adjusted by adjusting the rivets, so as to ensure the stability of the window sash when it is closed.

[0010] Furthermore, a fixing plate is rotatably mounted on the upper surface of the frame fixing plate by being riveted by tightening fasteners, and a limiting block is provided on one side of the fixing plate on the upper surface of the frame fixing plate to limit the fixing plate from rotating in the opposite direction in the initial position.

[0011] Limit blocks are provided on the frame fixing plate to ensure that the fixing plate rotates in only one direction, preventing reverse rotation and accidental operation. When the fixing plate is in the initial position, the limit blocks restrict the reverse rotation of the fixing plate to prevent accidental operation and make it impossible to install the fixing plate.

[0012] Furthermore, a rubber washer is fitted between the fixing plate and the frame fixing plate of the tightening fastener.

[0013] By using rubber gaskets, the sealing at the joints can be improved, thereby improving the sealing when the window sash is closed.

[0014] Furthermore, a limiting groove is provided through the middle of the frame fixing plate along the length direction, and a limiting post located in the limiting groove and slidably connected to the limiting groove is vertically riveted to the end of the rotating plate near the stop block.

[0015] The limiting groove on the frame fixing plate is used to cooperate with the limiting post on the rotating plate to ensure the smooth opening and closing of the window sash.

[0016] Furthermore, the surface of the sliding head is recessed to form a polygonal groove that can be inserted and mated with a wrench.

[0017] The sliding head has a polygonal groove recessed on its surface, which can be used in conjunction with a wrench. By rotating the sliding head with the wrench, the position of the pin can be adjusted, thereby adjusting the inner and outer distance of the window sash and adjusting the sealing between the window sash and the window frame.

[0018] Furthermore, a receiving groove is recessed in the middle of the connecting rod, and a ring-shaped locking spring is engaged in the receiving groove. The diameter of the ring end of the locking spring near the connecting plate is smaller than the diameter of the ring end of the locking spring away from the connecting plate. The end of the connecting plate is sharpened and a fixing post extending into the locking spring is riveted to the bottom surface of the tip.

[0019] The two ends of the locking spring have different diameters. The smaller diameter end can clamp and limit the fixing post after it slides in, thereby limiting the opening of the window sash and keeping it stable in the open state. This improves the stability of the window sash and helps to stabilize the opening angle of the window sash.

[0020] Furthermore, a fixing groove is formed on one end surface 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 groove by internal hexagonal cylindrical end screws. Correspondingly, a clearance groove is opened on the sliding plate to avoid the vertical internal hexagonal cylindrical end screws.

[0021] The connecting rod is fixed in the window sash groove by the fixing block in the fixing groove and the vertical hexagonal cylindrical end screw, which can be used for positioning and installation of the connecting rod.

[0022] 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, and the other end of the V-shaped rod is hinged to the frame fixing plate. Near its hinge point with the frame fixing plate, the V-shaped rod is hinged to the rotating plate below.

[0023] The beneficial effects of this utility model are:

[0024] In this invention, a rotating plate is mounted on a connecting plate, and the rotating plate is equipped with a stop block. The connecting plate is equipped with a horizontal sliding groove and an oblique sliding groove. The pin can slide within the sliding groove on the connecting plate to realize the opening, locking, and unscrewing of the window sash. When the sliding head of the pin is in the locked position within the sliding groove on the connecting plate, the stop block on the rotating plate functions as a stop. That is, when the pin is in the locked position, the stop block and the horizontal sliding groove together restrict the movement of the pin, making it difficult for the window to be opened by external force when the window sash is closed, thereby improving its sealing performance and enhancing the sealing and airtightness of the window sash in both the outdoor and indoor directions.

One end of the rotating plate 5 is slidably hinged to the frame fixing plate 1. The rotating plate 5 has a stop block 18 extending from this end, which can abut against the sliding head 28 when the window is closed. The other end of the rotating plate 5 is hinged to the end of the lower plate 24 of the connecting plate 16. A connecting rod is hinged to the middle part of the rotating plate 5 below the frame fixing plate 1. One end of the connecting rod is hinged to the lower plate 24, and the other end of the connecting rod is hinged to the bottom end of the frame fixing plate 1. The connecting rod includes a V-shaped rod 27 and a swing rod 25. One end of the V-shaped rod 27 is hinged to one end of the swing rod 25, and the other end of the V-shaped rod 27 is hinged to the frame fixing plate 1. The V-shaped rod 27 is hinged to the rotating plate 5 below it near the hinge point with the frame fixing plate 1.

[0033] In this embodiment, the rotating plate 5 includes a straight plate and a curved 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 stop plate 26 parallel to the straight plate. A stop block 18 extends from the stop plate 26. When the window is closed, the stop block 18 is located above one side of the horizontal sliding groove 20 in the length direction.

[0034] An anti-sway plate 7 located at the end of the transverse slide groove 20 is installed on the lower plate surface of the connecting plate 16 via adjusting rivets 6. The anti-sway plate 7 is arranged along the width direction of the lower plate 24, and one end of it is bent on one side of the length direction of the lower plate 24 to form a bend.

[0035] A fixing plate 2, riveted to the upper surface of the frame fixing plate 1 by tightening the fixing member 4, is rotatably mounted. A limiting block 17 is provided on one side of the fixing plate 2 on the upper surface of the frame fixing plate 1 to limit the fixing plate 2 from rotating in the reverse direction in the initial position. A rubber washer 3 is sleeved between the fixing plate 2 and the frame fixing plate 1 by tightening the fixing member 4.

[0036] A limiting groove is provided through the middle of the frame fixing plate 1 along the length direction, and a limiting post located in the limiting groove and slidably connected to the limiting groove is vertically riveted to one end of the rotating plate 5 near the stop block 18.
