DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] It should be noted that, in the description of the present invention, terms such as "center", "upper", "lower", "horizontal", "inner", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0021] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figures 1 to 6As shown, a corner transmission device for aluminum-plastic doors and windows is applied to existing translation suspended sliding windows; the translation suspended sliding window includes an outer frame 5, and the corner transmission device is provided with two, which are respectively fixed to the upper and lower ends of the outer frame 5; the outer frame 5 is provided with a first handle 3, a first guide plate 2, and a first transmission rod 1; the first guide plate 2 is fixedly connected to the outer frame 5, and the first handle 3 and the first transmission rod 1 are movably arranged on the outer frame 5, and rotating the first handle 3 can drive the first transmission rod 1 to move up and down; the corner transmission device includes an inclined hole guide groove module 8, a first transmission bar 9 and a first pulley frame 11; the first transmission rod 1 is fixedly connected to the inclined hole guide groove module 8; the inclined hole guide groove module 8 is vertically movable and placed in the first pulley frame 11; the first transmission bar 9 is horizontally movable and placed in the first pulley frame 11; one end of the first transmission bar 9 is integrally provided with a guide rod 10, and a bearing is provided on the guide rod 10; the inclined hole guide groove module 8 is provided with a curved inclined through hole 7 matching the guide rod 10; the first pulley frame 11 is provided with a horizontal through hole 12 matching the guide rod 10; one end of the guide rod 10 passes through the inclined through hole and extends into the horizontal through hole 12. When the first handle 3 is rotated, the first transmission rod 1 is driven to move upward or downward, and the first transmission rod 1 drives the inclined hole guide groove module 8 to move up and down; when the inclined hole guide groove module 8 moves upward or downward, the guide rod 10 on the first transmission bar 9 slides along the curved inclined through hole 7 on the inclined hole guide groove module 8. At the same time, because the guide rod 10 is also placed in the horizontal through hole 12 of the first pulley frame 11, under the dual restrictions of the curved inclined through hole 7 and the horizontal through hole 12, as the inclined hole guide groove module 8 moves upward, the transmission bar moves to the right in the horizontal through hole 12, and as the inclined hole guide groove module 8 moves downward, the transmission bar moves to the left in the horizontal through hole 12; the curved inclined through hole 7 can make the movement of the transmission bar smoother.

[0023] Furthermore, two linear guide grooves 14 and two oblique hole guide grooves 13 are provided on the first transmission bar 9 , and the oblique hole guide groove 13 is located between the two linear guide grooves 14 .

[0024] Furthermore, a pulley block guide rail is fixedly provided on the first pulley frame 11; the first pulley frame 11 is provided with a pulley block transmission bar linear positioning groove bearing hole and an axle rod and a pulley block inward and outward moving directional groove, which are commonly used technical means; the pulley block 6 is a commonly used component on a translational suspended window (the upper part of the pulley block 6 is a pulley block with a stop wheel that can be moved left and right, inward and outward, and the lower part is a pulley block that can be moved left and right, inward and outward, which are used in conjunction; referred to as the pulley block); the pulley block 6 is slidably arranged on the pulley block guide rail through an inward and outward moving linear bearing; the linear guide groove 14 of the first transmission bar 9 acts on the first pulley frame 11, limiting the first transmission bar 9 to horizontal movement; at the same time, the oblique hole guide groove 13 of the first transmission bar 9 acts on the pulley block 6 inside the first pulley frame 11, so that the pulley block 6 moves outward along the pulley block guide rail, and the window sash 4 passes The handle controls the distance of inward and outward movement, and adjusts the distance between the window sash of the sliding suspended window and the sealing strip on the outer fixed frame, so that the ventilation volume at the entire openable window can be adjusted to achieve air intake without dust intake, until the window sash 4 is tightly attached to the self-priming sealing strip of the outer fixed frame of the sliding suspended window, completely blocking the air circulation, causing the entire openable window to be airtight, blocking the air circulation, and achieving the airtight effect of the casement window. The reverse action is performed, which is the opening action. The window sash 4 is separated from the self-priming sealing strip and strip of the outer fixed frame and can be freely translated left and right. Its left and right translation stroke depends on the length of the sliding track, and the window sash does not contact the sealing strip and strip on the window frame when it moves left and right; the linkage execution relationship of the pulley group 6, the inner and outer moving linear bearings and the opening and closing actions of the window sash 4 are all existing structural designs.
