[0042] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0043] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the modules or components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0045] See also Figure 1-12The utility model provides a side-mounted transmission device universal for left and right assembly, including a fixed box 1 and a transmission mechanism 2, the fixed box 1 is provided with a first concave cavity 11, and the transmission mechanism 2 is arranged in the first concave cavity 11; specifically, the transmission mechanism 2 includes a gear 21, a first rack 22, a second rack 23 and a slider 25, the gear 21 is located in the middle of the first concave cavity 11, the first rack 22 and the second rack 23 are respectively arranged on the left and right sides of the gear 21, and the relative inner sides of the first rack 22 and the second rack 23 are meshed with the gear 21 for transmission, the outer side of the first rack 22 is in contact with the side wall of the first concave cavity 11, and the outer side of the second rack 23 is in contact with the other side wall of the first concave cavity 11; a connecting strip 26 is movably provided at the upper end of the slider 25, and the slider 25 can be selectively connected to the first rack 22 or the second rack 23 through the connecting strip 26; similarly, the left and right side walls of the slider 25 are in contact with the left and right side walls of the first concave cavity 11.

[0046] In addition, the side-mounted transmission device also includes a transmission bar 3, one end of which is connected to the slider 25, and the other end of which is disposed outside the first concave cavity 11 of the fixed box 1. Therefore, when the gear 21 is driven to rotate left and right, the first rack 22 and the second rack 23 can be driven to move up and down in the first concave cavity 11 through tooth meshing, thereby driving the slider 25 to move up and down in the first concave cavity 11, and finally realizing the up and down movement of the transmission bar 3.

[0047] When the side-mounted transmission structure is adopted, when the side-mounted transmission is installed on the left or right side of the profile frame, the slider 25 can be selectively connected to the first rack 22 or the second rack 23 through the connecting bar 26, so that when the gear 21 is driven to rotate to the left or right, it can move through the first rack 22 or the second rack 23 to drive the transmission bar 3 to move, and then drive the locking transmission to open and close the door and window. Therefore, the side-mounted transmission of the present application can be universally assembled on the left and right sides, thereby improving its applicability, and there is no need to design two specifications and styles, thereby reducing costs.

[0048] More specifically, the gear 21 is provided with a transmission shaft 24 arranged perpendicular thereto, and the transmission shaft 24 passes through the first cavity 11 and is in transmission connection with the handle. Thus, the gear 21 can be driven to rotate by rotating the handle, thereby driving the transmission bar 3 to move up and down, and the operation is simple and convenient. Preferably, the transmission shaft 24 and the gear 21 are integrally formed, and the structure is more stable and has higher strength.

[0049] More specifically, a mounting slot is provided on the slider 25 , one end of the transmission bar 3 is inserted into the mounting slot and the two are connected by a locking screw 7 to achieve fixation.

[0050] Furthermore, a through slot 251 is provided at the upper end of the slider 25, and the through slot 251 is extended in the left-right direction, and the connecting bar 26 is slidably inserted into the through slot 251. In addition, a first clamping hole 221 is provided on the first rack 22, and a second clamping hole 231 is provided on the second rack 23. When the handle is rotated to drive the first rack 22 and the second rack 23 to move up and down until they are flush with each other, the first clamping hole 221, the second clamping hole 231 and the through slot 251 are all interconnected and aligned, and then the connecting bar 26 is driven to move in the left-right direction so that the two ends of the connecting bar 26 are respectively inserted into the first clamping hole 221 or the second clamping hole 231 to achieve the connection between the slider 25 and the first rack 22 or the second rack 23.

[0051] Preferably, a first through hole 12 and a second through hole 13 are respectively provided on the left and right side walls of the fixing box 1. When the handle is rotated to drive the first rack 22 and the second rack 23 to move up and down until they are flush with each other, the first through hole 12 is connected to the first clamping hole 221, and the second through hole 13 is connected to the second clamping hole 231. The user can use a tool to pass through the first through hole 12 to push the connecting bar 26 into the second clamping hole 231, or use a tool to pass through the second through hole 13 to push the connecting bar 26 into the first clamping hole 221, thereby realizing the connection between the slider 25 and the first rack 22 or the second rack 23 through the connecting bar 26.

[0052] When reversing operation is required, the gear 21 is driven to rotate by turning the handle, and the first rack 22 or the second rack 23 on both sides of the gear 21 are moved to be flush with each other, and then a tool is used to push the connecting bar 26 to move into the first rack 22 until it is completely disengaged from the second rack 23, or the connecting bar 26 is pushed to move into the second rack 23 until it is completely disengaged from the first rack 22. At this time, reversing can be achieved. The whole operation is simple and convenient, which greatly improves the installation efficiency.

[0053] Furthermore, in order to improve the connection stability between the slider 25 and the first rack 22 or the second rack 23, the side-mounted transmission device further includes a first elastic member 28 and a positioning bead 27. The connecting bar 26 is provided with a first mounting groove 261, and the first mounting groove 261 is extended in the up-down direction. Preferably, the first elastic member 28 is a spring, which is provided in the first mounting groove 261 and abuts against the connecting bar 26 at one end and abuts against the positioning bead 27 at the other end. Under the elastic force of the spring, the positioning bead 27 can be driven to abut against the slider 25. The slider 25 is provided with a first positioning hole 252 and a second positioning hole 253 which are connected to the through groove 251 and are arranged at intervals. The first positioning hole 252 is provided near the first clamping hole 221, and the second positioning hole 253 is provided near the second clamping hole 231.

[0054] Thus, when the connecting strip 26 is driven to move, the positioning bead 27 can be driven to move synchronously until one end of the connecting strip 26 is inserted into the first clamping hole 221 and the positioning bead 27 is clamped into the first positioning hole 252 under the action of the spring, at which time the connecting strip 26 is positioned and clamped, thereby realizing the connection and fixation between the slider 25 and the first rack 22. Similarly, when the connecting strip 26 is driven to move in the opposite direction until the other end of the connecting strip 26 is inserted into the second clamping hole 231 and the positioning bead 27 is clamped into the second positioning hole 253 under the action of the spring, at which time the connecting strip 26 is positioned and clamped, thereby realizing the connection and fixation between the slider 25 and the second rack 23.

[0055] It should be noted that the diameter of the positioning bead 27 is larger than the diameter of the first positioning hole 252 and the second positioning hole 253. When the positioning bead 27 is engaged with the first positioning hole 252 or the second positioning hole 253, the positioning bead 27 is only partially engaged. Therefore, when the connecting strip 26 is pushed to move left and right, the positioning bead 27 can be driven by the connecting strip 26 to disengage from the first positioning hole 252 or the second positioning hole 253, thereby driving the positioning bead 27 to move.

[0056] Furthermore, the side-mounted transmission device further comprises a cover plate 4 covering the fixed box 1, the cover plate 4 presses on the first rack 22, the second rack 23 and the slider 25, thereby restricting them in the first concave cavity 11, so that they can only move up and down in the first concave cavity 11. In addition, the side-mounted transmission device further comprises a transmission panel 5 connected to the fixed box 1, a second concave cavity 51 is formed in the transmission panel 5, the other end of the transmission bar 3 passes through the fixed box 1 and extends into the second concave cavity 51, and the two side walls of the transmission bar 3 are respectively in contact with the two side walls of the second concave cavity 51, thereby restricting the transmission bar 3 to only move up and down in the second concave cavity 51.

[0057] Furthermore, the side-mounted transmission device further comprises a second elastic member 6, preferably, the second elastic member 6 is a booster spring, the slider 25 is further provided with a second mounting groove 254, the booster spring is arranged in the second mounting groove 254 and one end of the booster spring abuts against the slider 25, and the other end abuts against the fixing box 1. Preferably, two booster springs are provided and are spaced apart from each other in the left-right direction.

[0058] When the side-mounted transmission device of the present application is used, the lower end of the transmission bar 3 is connected to the pulley assembly (not shown in the figure). When the transmission bar 3 is driven to move up and down, the pulley assembly can be driven to lift and lower, thereby driving the doors and windows to rise or sink. Since the weight of the doors and windows is large, when the handle is turned to drive the doors and windows to rise, a large force is required to turn the handle. By setting a booster spring, when the handle is turned to lift the doors and windows, the booster spring can release elastic force to drive the doors and windows to rise, so that there is no need to use a large force to turn the handle, which is more convenient.

[0059] In this embodiment, two first limiting columns 14 are spaced apart in the left-right direction in the first concave cavity 11 of the fixing box 1 , and the other end of the assisting spring abuts against the first limiting column 14 .

[0060] Furthermore, a second limiting column 15 and a third limiting column 16 are integrally formed in the first concave cavity 11 of the fixed box 1, and the second limiting column 15 is used to abut against the first rack 22 to limit the movement of the first rack 22, and the third limiting column 16 is used to abut against the second rack 23 to limit the movement of the second rack 23.

[0061] In this embodiment, the two first limit columns 14, the second limit column 15 and the third limit column 16 are respectively arranged at the four corners of the fixed box 1, and the cover plate 4 is provided with mounting holes corresponding to the positions of the limit columns. The cover plate 4 can be connected to the fixed box 1 by passing bolts through the mounting holes and fixing them on the limit columns.

[0062] See also Figure 7-12 , the working process of the side-mounted transmission of the present application is as follows:

[0063] First, if Figure 7-8 As shown, at this time, the side-mounted transmission device is installed on one side of the door frame, and the upper end of the first rack 22 abuts on the second limiting column 15 to achieve the limit of the rotation of the handle, and the lower end of the first rack 22 is connected and fixed to the slider 25 through the connecting bar 26; when the handle is driven to rotate 180 degrees clockwise to the right, the first rack 22 can be driven to move downward, and then the slider 25 and the transmission bar 3 move downward. At this time, the second rack 23 moves upward and its upper end abuts on the third limiting column 16 to achieve the limit of the rotation of the handle, as shown in FIG. Figure 8 As shown, it can be seen that the handle can be rotated 180 degrees clockwise or counterclockwise on the right side and drive the transmission bar 3 to move up and down.

[0064] When the side-mounted actuator is installed on the other side of the door frame, the handle is first turned to move the first rack 22 and the second rack 23 up and down until they are flush with each other. Fig. 9 Then push the connecting strip 26 to move until the connecting strip 26 is fully inserted into the second card hole 231 and the positioning bead 27 is clamped in the second positioning hole 253, at which time the slider 25 is disengaged from the first rack 22 and is fixedly connected to the second rack 23, as shown Fig.10 Then the handle is driven to rotate 45 degrees clockwise, at which time the upper end of the second rack 23 abuts against the third limiting column 16 to limit the rotation of the handle, and the second rack 23 drives the slider 25 and the transmission bar 3 to move upward, as shown Fig.11As shown; then the handle is driven to rotate 180 degrees counterclockwise on the left side, which can drive the second rack 23 to move downward and then the slider 25 and the transmission bar 3 to move downward. At this time, the first rack 22 moves upward and its upper end abuts against the second limiting column 15 to achieve the limit of the rotation of the handle, as shown Fig.12 As shown, it can be seen that when the slider 25 is connected to the second rack 23 through the connecting bar 26, the handle can rotate 180 degrees clockwise or counterclockwise on the left side and drive the transmission bar 3 to move up and down.

[0065] Therefore, the side-mounted transmission of the present application can be used for both left and right assembly, thereby improving its applicability and reducing costs.

[0066] In summary, the utility model provides a side-mounted transmission that is universal for left and right assembly, which has the following beneficial effects:

[0067] (I) When the side-mounted transmission of the utility model is installed on the left or right side of the profile frame, the slider 25 can be selectively connected to the first rack 22 or the second rack 23 through the connecting bar 26, so that when the driving gear 21 rotates to the left or right, it can move through the first rack 22 or the second rack 23 to drive the transmission bar 3 to move, thereby realizing the transmission of the door and window. Therefore, the side-mounted transmission of the present application can be universally assembled on the left and right, thereby improving its applicability, and there is no need to design two specifications and styles, thereby reducing costs.

[0068] (ii) When the side-mounted transmission of the utility model needs to be reversed, the gear 21 is rotated to drive the first rack 22 and the second rack 23 to move flush with each other, and then a tool is used to push the connecting bar 26 to move into the first rack 22 until it is completely disengaged from the second rack 23, or the connecting bar 26 is pushed to move into the second rack 23 until it is completely disengaged from the first rack 22, so that the connecting rack can be switched to achieve reversal. The entire operation is simple and convenient, which greatly improves the installation efficiency.
