In addition, the side-mounted transmission device also includes a transmission bar 7, one end of which is connected to the sliding seat 4, and the other end of which passes through the box body 1.

[0041] Therefore, when the handle is rotated to drive the cam 2 to rotate, the sliding seat 4 can be driven to move up and down in the installation cavity 101 through the connecting piece 5, and then the transmission bar 7 can be driven to move up and down, and finally the locking transmission device can be driven to realize the opening and closing of the door and window.

[0042] The side-mounted transmission device of the present application can be used in conjunction with a side-mounted handle. When the handle is rotated, it can drive the transmission bar 7 to move up and down through the transmission cooperation of the cam 2, the connecting plate 5 and the sliding seat 4 in sequence. It has a simple structure, is easy to operate and is highly practical.

[0043] In this embodiment, the transmission shaft 3 and the cam 2 are integrally formed, and the structure is more stable and has higher strength.

[0044] Furthermore, the cam 2 is provided with a first mounting groove 201 and a first mounting hole 202 connected to the first mounting groove 201, and a first through hole 501 is provided at one end of the connecting piece 5. When one end of the connecting piece 5 is inserted into the first mounting groove 201 and the first mounting hole 202 is aligned with the first through hole 501, one end of the connecting piece 5 can be hinged to the cam 2 by using a latch 6 passing through the first mounting hole 202 and the first through hole 501; similarly, the sliding seat 4 is provided with a second mounting groove 401 and a second mounting hole 402 connected to the second mounting groove 401, and a second through hole 502 is provided at the other end of the connecting piece 5.

[0045] Furthermore, a first card slot 404 and a screw hole 405 connected to the first card slot 404 are provided on the sliding seat 4, and a fourth through hole 701 is provided at the upper end of the transmission bar 7. When the upper end of the transmission bar 7 is inserted into the first card slot 404 and the fourth through hole 701 is aligned with the screw hole 405, the transmission bar 7 can be connected and fixed to the sliding seat 4 by using a locking screw 11 to pass through the fourth through hole 701 and be threadedly fixed in the screw hole 405.

[0046] Furthermore, since the handle is installed on the side of the door frame profile, in order to prevent the handle from interfering with the door and window after rotating to a certain angle, the box body 1 is further provided with a limit baffle 102 located in the installation cavity 101, and the limit baffle 102 is used to abut against the cam 2 to limit the rotation of the cam 2, thereby limiting the rotation of the handle. Preferably, the limit baffle 102 is integrally formed on the box body 1.

[0047] It should be noted that when the side-mounted actuator is installed on one side of the door frame profile, after the handle is rotated and the cam 2 is driven to rotate clockwise or counterclockwise at a certain angle on the left side, the cam 2 will abut against the limit baffle 102, thereby limiting the handle to rotate only on the left side. Figure 8-9 Of course, in other embodiments, when the side-mounted actuator is installed on the other side of the door frame profile, the position of the limit baffle 102 needs to be changed to limit the handle to rotate only on the right side, thereby preventing the handle from interfering with the door and window, which is not limited here.

[0048] Furthermore, the side-mounted transmission device further comprises a cover plate 8 covering the box body 1, the cover plate 8 presses on the cam 2 and the sliding seat 4 and restricts the two in the installation cavity 101, so that the two can only move in the installation cavity 101. In addition, the side-mounted transmission device further comprises a transmission panel 9 connected to the box body 1, a concave cavity 901 is formed in the transmission panel 9, the other end of the transmission bar 7 passes through the box body 1 and extends into the concave cavity 901, and the left and right side walls of the transmission bar 7 are respectively in contact with the left and right side walls of the concave cavity 901, so that the transmission bar 7 can only move up and down in the concave cavity 901.

[0049] Among them, the box body 1 is provided with a second card slot 105 and card blocks 106 located on the left and right sides of the second card slot 105, one end of the transmission panel 9 is adapted to the shape of the second card slot 105 and card holes 902 are provided on the left and right sides; therefore, when one end of the transmission panel 9 is inserted into the second card slot 105 until the card block 106 is engaged with the card hole 902, the connection and fixation of the transmission panel 9 and the box body 1 can be achieved.

[0050] Furthermore, the side-mounted transmission device further comprises a booster spring 10, and the sliding seat 4 is further provided with a third mounting groove 403.

Preferably, two booster springs 10 are provided and are spaced apart from each other in the left-right direction.

[0051] When the side-mounted transmission device of the present application is used, the lower end of the transmission bar 7 is connected to the pulley assembly (not shown in the figure) at the bottom of the door and window. When the transmission bar 7 is driven to move up and down, the pulley assembly can be driven to perform lifting and lowering actions, thereby driving the door and window to rise or sink. Due to the heavy weight of the door and window, when the handle is turned to drive the door and window to rise, a large force is required to turn the handle; by providing a booster spring 10, when the handle is turned to lift the door and window, the booster spring 10 can release the elastic force to drive the door and window to rise, so that there is no need to use a large force to turn the handle, which is more convenient.

[0052] In this embodiment, the box body 1 is further provided with a stopper 103 located in the installation cavity 101, and the other end of the booster spring 10 abuts against the stopper 103. Preferably, the stopper 103 and the box body 1 are integrally formed.

Thus, the cover plate 8 can be connected and fixed to the box body 1 by fasteners passing through the third through holes 801 and being fixed in the mounting posts 104. Preferably, the mounting posts 104 are nut posts, and the fasteners are bolts adapted to the nut posts.

[0054] In summary, the utility model provides a side-mounted transmission device, which can be used in conjunction with a side-mounted handle. When the handle is rotated, it can drive the transmission bar 7 to move up and down through the transmission cooperation of the cam 2, the connecting plate 5 and the sliding seat 4 in sequence.
