Summary of the invention

[0004] The present invention aims to solve the shortcomings of the above-mentioned prior art and provides a door and window inclined pull rod device that can prevent doors and windows from being blown and swayed by wind when they are hung down (or up), and ensure the stability of the doors and windows when they are hung down (or up), thereby meeting the requirements that the doors and windows that are hung up or down can be stabilized there after being opened, without being blown and swayed by wind, and without making noise.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: the door and window inclined pull rod device comprises a mounting rod installed on the door and window, a movable connecting rod slidably connected to the mounting rod is provided below the mounting rod, a first guide groove is provided on the mounting rod, a pin shaft which can be movably connected in the first guide groove and can prevent the mounting rod from escaping from the first guide groove, a rotating connecting rod is provided at the side end of the mounting rod, the inner side of the rotating connecting rod is hinged at the pin shaft, and the other side end of the rotating connecting rod is connected to the mounting plate; a shift block is provided between the mounting rod and the rotating connecting rod, one end of the shift block is hinged on the rotating connecting rod, and the middle axis of the shift block is connected to the mounting rod; a shift groove is provided on the shift block, a second guide groove is provided on the mounting rod, a slide plate is slidably connected to the mounting rod, the slide plate and the movable connecting rod are fixed together, a cylindrical block is fixed on the slide plate, the side end of the shift groove is provided with an anti-rotation plane opened on the shift block, and the cylindrical block is provided with a matching plane matching the anti-rotation plane. The functions of the mounting rod, movable connecting rod, first guide groove, pin shaft, rotating connecting rod, shift block, shift groove, second guide groove, slide plate, connecting block and cylindrical block here are to provide support when the doors and windows are hung down to prevent them from flipping over and falling down; the function of the anti-rotation plane and matching plane here is to make the anti-rotation plane on the shift block abut against the matching plane of the cylindrical block, so that when the doors and windows are hung down (can be used for hanging doors and windows), they will not be attracted to shake by negative pressure caused by external wind, ensuring that the doors and windows can always remain stable under the action of external wind, which can not only reduce noise but also increase the service life of the inclined rod; the function of the mounting plate here is to install the rotating connecting rod on the door and window frame through the mounting plate.

[0006] Further improvement, a connecting block is provided in the second guide groove to slide with it, and the slide plate and the moving connecting rod are connected and fixed by the connecting block. The function of the connecting block here is to enable the moving connecting rod to drive the slide plate to move synchronously, and the connecting block slides in the second guide groove, so that the moving connecting rod can drive the slide plate to move more stably.

[0007] Further improvement, a limit card slot is provided at the bottom of the shift block, and a limit card block is fixed on the movable connecting rod, which passes through the second guide slot and cooperates with the limit card slot. The function of the limit card slot and the limit card block is to further clamp the door and window after the door and window are suspended downward, so as to avoid the problem of the door and window shaking caused by the external air pressure.

[0008] Further improvement, a raised anti-outward push-out block is fixed on the rotating connecting rod, and a limiting notch is provided on the shifting block to cooperate with the anti-outward push-out block. The function of the anti-outward push-out block and the limiting notch is that when the door and window are closed after being hung down, the anti-outward push-out block cooperates with the limiting notch to prevent the door and window from further turning outward to the outside of the window, thereby preventing the door and window from being pushed in the reverse direction.

[0009] Further improvement, a third guide groove is provided on the mounting rod, a locking block located at the third guide groove is fixed on the movable connecting rod, a locking opening is provided on the locking block, and a first clamping column matched with the locking opening is fixed on the rotating connecting rod. Here, the second guide groove, the locking block and the locking opening are used to completely lock the door and window through the first clamping column and the outer end surface of the locking opening of the locking block when the door and window are suspended downward, so as to prevent the door and window from being opened, and the problem of the door and window being slightly pushed open will not occur when the door and window are pushed.

[0010] For further improvement, the side end of the first clamping column is provided with a second clamping column fixed at the rotating connecting rod, and the first clamping column and the second clamping column are staggered inside and outside. The purpose of the staggered arrangement of the first clamping column and the second clamping column is that when the door and window are in the state of hanging down and opening, the first clamping column and the outer end surface of the lock block lock mouth are clamped together; when the door and window are in the state of hanging up and opening, the second clamping column and the inner end surface of the lock block lock mouth are clamped together; this arrangement meets the requirement of being able to lock the door and window regardless of whether it is hanging down or hanging up, and the versatility will be stronger, without the need for two inclined rod devices.

[0011] Further improvement, the upper and lower surfaces of the moving connecting rod are provided with a self-lubricating layer. The function of the self-lubricating layer here is to use the interlocking mechanism (door and window turning angle) to drive the moving connecting rod to move, with low friction resistance and low noise, and easy to drive; the self-lubricating layer here is made of tin bronze material.

[0012] To further improve the invention, a fine-tuning rod is provided at the side end of the rotating connecting rod, a pair of relatively arranged vertical toggle blocks are fixed on the top surface of the outer end of the rotating connecting rod, a fourth guide groove is formed on the rotating connecting rod, a shaft rod passing through the fourth guide groove is hinged on the fine-tuning rod, an eccentric dial wheel located between the two vertical toggle blocks is eccentrically fixed on the shaft rod, a hexagonal groove coaxially arranged with the shaft rod is formed on the top of the eccentric dial wheel, a fifth guide groove is formed on the fine-tuning rod, the fine-tuning rod and the rotating connecting rod are riveted at the fifth guide groove by a first rivet, a sixth guide groove is formed on the fine-tuning rod, and an insert block matching the sixth guide groove is fixed on the rotating connecting rod. The functions of the fine-tuning rod, the vertical toggle block, the fourth guide groove, the shaft rod, the fifth guide groove of the eccentric dial wheel, and the first rivet here are to rotate the eccentric dial wheel, thereby pressing the vertical toggle block, and then fine-tuning the position of the fine-tuning rod. In an environment where the size of the door and window frames is not very precise, the purpose of efficient installation can be achieved by fine-tuning the position of the mounting plate, and the situation that the installation cannot be performed due to the size of the door and window frames will not occur; the function of the hexagonal groove here is that because the riveting is relatively tight, sometimes the eccentric dial wheel cannot be moved by hand to push the fine-tuning rod to move. At this time, the hexagonal wrench is inserted into the hexagonal groove and rotated, so that the eccentric dial wheel can be easily driven to rotate; the function of the sixth guide groove and the insert block here is to ensure that the fine-tuning rod moves in the length direction of the rotating connecting rod without the fine-tuning rod rotating, thereby ensuring the accurate movement direction of the fine-tuning rod.

[0013] For further improvement, an arc limit groove is opened on the mounting plate, a connecting plate is installed on the fine-tuning rod, a support plate is provided under the connecting plate, the inner end of the support plate is hinged at the side end of the fine-tuning rod, and a rotating plate is hinged at the outer end of the support plate. The rotating plate is hinged at the mounting plate, and a limit column matching the arc limit groove is fixed on the top of the rotating plate. An eighth guide groove is opened on the fine-tuning rod, and a second rivet is installed between the connecting plate and the eighth guide groove. Here, the functions of the arc limit groove, connecting plate, support plate, rotating plate, limit column, eighth guide groove and second rivet are to set and adjust the opening angle of doors and windows to correspond to different applicable environments. In some environments, large ventilation volume is required, and the preset opening angle can be set larger. In some environments, the ventilation volume required is not so large, and the preset opening angle can be set smaller, so as to achieve a reasonable opening angle with stronger versatility. The opening angle of the lower hanging doors and windows is adjusted in the following way: when the doors and windows are in a closed state, the limit column is located at the highest position of the arc limit groove. When the doors and windows are lowered, the limit column will be located at the bottom of the arc limit groove. After adjusting the position of the connecting plate in the eighth guide groove, it is riveted by the second rivet. The position adjustment of the connecting plate will push the support plate to rotate, thereby adjusting the rotating plate to rotate together, and then adjusting the position of the limit column at the highest point of the arc limit groove. Therefore, when the doors and windows are lowered, the arc drop distance of the limit column in the arc limit groove can be adjusted, so as to adjust the opening angle of the lower hanging doors and windows, thereby adapting to the use environment with different lower hanging opening angles.

[0014] For further improvement, a retaining frame is fixed on the mounting rod, a guide block is fixed on the retaining frame, a seventh guide groove which is plugged with the guide block is provided on the movable connecting rod, a filler plate which prevents the movable connecting rod from shifting up and down is provided between the mounting rod and the movable connecting rod, and the filler plate is fixed on the mounting rod; a mounting hole is provided on the side end of the movable connecting rod. The function of the retaining frame, the guide block, the seventh guide groove, and the filler plate here is to enable the movable connecting rod to be assembled on the mounting rod without falling off longitudinally, and to move without shaking, and to keep moving smoothly within a specific range. The function of the mounting hole here is to facilitate the installation of the linkage mechanism (door and window turning angle) on the doors and windows, so as to facilitate and efficiently drive the movable connecting rod to move, thereby driving the matching plane to leave the anti-rotation plane, so as to facilitate unlocking or locking the doors and windows when they are closed.

[0015] The beneficial effects of the present invention are:

[0016] 1). Through the installation rod, movable connecting rod, first guide groove, pin shaft, rotating connecting rod, shift block, shift groove, second guide groove, slide plate, connecting block and cylindrical block, doors and windows can be supported when hanging down to prevent them from turning over and falling down;

[0017] 2). Through the anti-rotation plane and the matching plane, the anti-rotation plane on the shift block can be placed against the matching plane of the cylindrical block, so that when the door and window are hung down (it can be used for hanging up the door and window), it will not be attracted to shake due to negative pressure caused by the outside wind, ensuring that the door and window can always remain stable under the action of the outside wind, which can not only reduce noise, but also increase the service life of the inclined rod;

[0018] 3) Through the fine-tuning rod, the vertical toggle block, the fourth guide groove, the shaft rod, the fifth guide groove of the eccentric dial wheel, and the first rivet, the eccentric dial wheel can be rotated to press the vertical toggle block, and then the position of the fine-tuning rod can be fine-tuned. In the environment where the size of the door and window frame is not very accurate, the position of the mounting plate can be fine-tuned to achieve the purpose of efficient installation, and the situation that the installation cannot be performed due to the size problem of the door and window frame will not occur;

[0019] 4). The opening angle of doors and windows can be adjusted through the arc limit groove, connecting plate, support plate, rotating plate, limit column, eighth guide groove and second rivet to correspond to different applicable environments. In some environments, large ventilation is required, and the preset opening angle can be set larger. In some environments, the ventilation is not so large, and the preset opening angle can be set smaller, so as to achieve a reasonable underhang opening angle, which is more versatile.

[0020] 5). Through the retaining frame, the guide block, the seventh guide groove and the filler plate, the movable connecting rod can be assembled on the mounting rod without falling off longitudinally, and will not shake when moving, and can be driven smoothly. BRIEF DESCRIPTION OF THE DRAWINGS
