Description

Technical Field

[0001] This invention belongs to the field of doors and windows, and particularly relates to a door and window and its transmission box. Background Technology

[0002] Existing door and window handles open or close by rotating in one direction (clockwise or counterclockwise) to a certain angle. Therefore, a manufactured drive box has a fixed drive direction, meaning it can only be installed on the left or right side of the window sash. However, due to the diverse applications of doors and windows, some drive boxes need to be installed on the left side, while others may need to be installed on the right side. The drive rods of drive boxes installed on the left and right sides have opposite drive directions. Therefore, it's inevitable that the purchased drive box will not match the actual application, requiring the purchase or replacement of a drive box that matches the installation location, thus delaying the door and window construction schedule. Summary of the Invention

[0003] The purpose of this invention is to provide a door and window and its transmission box. Installers can install the transmission box on the left or right side of the window sash according to the actual application, which has a wide range of applications.

[0004] This invention is implemented as follows: a transmission box for doors and windows includes a turntable and a transmission rod. The turntable has a connecting part that is connected to the handle for transmission. The transmission box also includes a first connecting rod, a second connecting rod, a first transmission plate, and a second transmission plate. One end of the first connecting rod is hinged to one side of the turntable, and the other end is hinged to one end of the first transmission plate. One end of the second connecting rod is hinged to the other side of the turntable, and the other end is hinged to one end of the second transmission plate. A first connecting block is fixed to the other end of the first transmission plate, and a second connecting block is fixed to the other end of the second transmission plate. The first connecting block or the second connecting block is detachably connected to the transmission rod through a connecting member, so that the first transmission plate or the second transmission plate drives the transmission rod to move linearly.

[0005] Furthermore, the first connecting block is provided with a first connecting hole, the second connecting block is provided with a second connecting hole, and the two ends of the transmission rod are respectively provided with a third connecting hole and a fourth connecting hole; the first connecting block and the transmission rod are detachably connected by inserting a connector into the first connecting hole and the third connecting hole; or, the second connecting block and the transmission rod are detachably connected by inserting a connector into the second connecting hole and the fourth connecting hole.

[0006] Furthermore, both the first connecting hole and the second connecting hole are threaded holes, and the connecting element is a screw.

[0007] Furthermore, one end of the transmission rod has at least two third connecting holes spaced apart along its length; the other end of the transmission rod has at least two fourth connecting holes spaced apart along its length; the first connecting block and the transmission rod are detachably connected by inserting a connector into the first connecting hole and one of the third connecting holes; the second connecting block and the transmission rod are detachably connected by inserting a connector into the second connecting hole and one of the fourth connecting holes.

[0008] Furthermore, the turntable has a first hinge hole and a second hinge hole on both sides respectively. One end of the first connecting rod is hinged to the first hinge hole through a first connecting shaft, and the other end of the first connecting rod extends into a first protrusion. The first transmission plate has a third hinge hole, and the first protrusion is hinged to the third hinge hole. One end of the second connecting rod is hinged to the second hinge hole through a second connecting shaft, and the other end of the second connecting rod extends into a second protrusion. The second transmission plate has a fourth hinge hole, and the second protrusion is hinged to the fourth hinge hole.

[0009] Furthermore, the transmission box also includes a mounting base and a cover plate. The cover plate and the mounting base are closed to each other to form an installation space between them. The first transmission plate and the second transmission plate are arranged at intervals and located within the installation space. The middle area of ​​the first transmission plate and the second transmission plate is provided with a strip-shaped hole extending along its length direction. The length of the strip-shaped hole is greater than the travel of the transmission rod. The turntable, the first connecting rod, the second connecting rod, the first connecting block, and the second connecting block are all located in the gap between the first transmission plate and the second transmission plate. A rotating boss extends from the side of the turntable away from the connecting part. The rotating boss passes through the strip-shaped hole of the first transmission plate and is rotatably connected to the inner sidewall of the mounting base.

[0010] Furthermore, after the mounting base and the cover plate are closed, a groove is formed on the top of both, and the transmission rod is slidably embedded in the groove.

[0011] Furthermore, the inner wall of the mounting base or cover plate is provided with a turntable limiting part, and a limiting protrusion extends outward from the periphery of the turntable. When the turntable rotates to the set limit position, the turntable limiting part and the limiting protrusion interfere with each other spatially, thus stopping the turntable.

[0012] To achieve the above objectives, the present invention also provides a door and window, including a window sash, a handle, and a transmission box of any of the above. The handle is installed on the frame of the window sash, the transmission box is embedded in the frame of the window sash, and the handle is connected to the turntable of the transmission box for transmission.

[0013] Furthermore, the handle is installed on the left or right side frame of the window sash, and the transmission box is embedded in the left or right side frame of the window sash.

[0014] Compared with the prior art, the beneficial effects of this invention are as follows:

[0015] The transmission box provided by this invention includes a turntable, a transmission rod, a first connecting rod, a second connecting rod, a first transmission plate, and a second transmission plate. One end of the first connecting rod is hinged to one side of the turntable, and the other end is hinged to one end of the first transmission plate. One end of the second connecting rod is hinged to the other side of the turntable, and the other end is hinged to one end of the second transmission plate. A first connecting block is fixed to the other end of the first transmission plate, and a second connecting block is fixed to the other end of the second transmission plate. Therefore, the transmission box of this invention has two sets of transmission components that can move in opposite directions. When installing doors and windows, installers can, depending on the specific location of the window sash (i.e., the left or right side of the window sash), first select one of the first or second connecting blocks to detachably connect with the transmission rod, and then install the transmission box on the left or right side of the window sash. This effectively avoids the problem of mismatch between the transmission box and the application environment, and has a wider range of applications compared to existing transmission boxes that can only be installed on one side of the window sash.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] Please refer to Figure 1 and Figure 2 The image shows a door and window transmission box 100 provided in this embodiment, including a mounting base 1, a cover plate 2, a turntable 3, a transmission rod 4, a first connecting rod 5, a second connecting rod 6, a first transmission plate 7, and a second transmission plate 8.

[0025] Please refer to Figure 3 After the cover plate 2 and the mounting base 1 are closed together, an installation space is formed between them. The first transmission plate 7 and the second transmission plate 8 are arranged at intervals and located within the installation space. After the mounting base 1 and the cover plate 2 are closed together, a sliding groove 9 is formed on the top of both, and the transmission rod 4 is slidably embedded in the sliding groove 9.

[0026] Please refer to Figure 4 One end of the first connecting rod 5 is hinged to one side of the turntable 3, and the other end is hinged to one end of the first transmission plate 7; one end of the second connecting rod 6 is hinged to the other side of the turntable 3, and the other end is hinged to one end of the second transmission plate 8. When the turntable 3 rotates, it can spatially interfere with the first connecting rod 5 and the second connecting rod 6, thereby driving the first connecting rod 5 and the second connecting rod 6 to rotate in opposite directions respectively. Preferably, in this embodiment, the outer surface of the turntable 2 matches the shape of the inner surface of the first connecting rod 5 and the inner surface of the second connecting rod 6, both being arc-shaped curved surfaces, so that the inner surfaces of the first connecting rod 5 and the second connecting rod 6 can completely fit against the outer surface of the turntable 3.

[0027] A first connecting block a is fixed to the other end of the first transmission plate 7, and a second connecting block b is fixed to the other end of the second transmission plate 8. The first connecting block a or the second connecting block b (one of the two) is detachably connected to the transmission rod 4 via a connecting piece c. Figure 3As shown, the turntable 3, the first connecting rod 5, the second connecting rod 6, the first connecting block a, and the second connecting block b are all located in the gap between the first transmission plate 7 and the second transmission plate 8.

[0028] Specifically, the first connecting block a has a first connecting hole a1 at its top, the second connecting block b has a second connecting hole b1 at its top, and the transmission rod 4 is located above the first connecting block a and the second connecting block b. The two ends of the transmission rod 4 have a third connecting hole 41 and a fourth connecting hole 42, respectively. The first connecting block a and the transmission rod 4 are detachably connected by inserting a connector c into the first connecting hole a1 and the third connecting hole 41; alternatively, the second connecting block b and the transmission rod 4 are detachably connected by inserting a connector c into the second connecting hole b1 and the fourth connecting hole 42, so that the first transmission plate 7 or the second transmission plate 8 drives the transmission rod 4 to move linearly. In this embodiment, both the first connecting hole a1 and the second connecting hole b1 are threaded holes, and the connector c is a screw; that is, the first connecting block a or the second connecting block b and the transmission rod 4 are detachably threaded connected.

[0029] Preferably, please refer to [the following text is missing]. Figure 4 One end of the transmission rod 4 has two third connecting holes 41 spaced apart along its length, and the other end has two fourth connecting holes 42 spaced apart along its length. The first connecting block a and the transmission rod 4 are detachably connected by inserting a connector c into the first connecting hole a1 and one of the third connecting holes 41. The second connecting block b and the transmission rod 4 are detachably connected by inserting a connector c into the second connecting hole b1 and one of the fourth connecting holes 42. By designing two connecting holes at each end of the transmission rod 4, the extension length of the transmission rod 4 can be adjusted, allowing the transmission rod 4 to engage with locking points at different distances.

[0030] For details, please refer to Figure 2 and Figure 4 The turntable 3 has a first hinge hole 31 and a second hinge hole 32 on both sides. One end of the first connecting rod 5 is hinged to the first hinge hole 31 via a first connecting shaft d, and the other end of the first connecting rod 5 extends into a first protrusion 51. The first transmission plate 7 has a third hinge hole 71, and the first protrusion 51 is hinged to the third hinge hole 71. One end of the second connecting rod 6 is hinged to the second hinge hole 32 via a second connecting shaft e, and the other end of the second connecting rod 6 extends into a second protrusion 61. The second transmission plate 8 has a fourth hinge hole 81, and the second protrusion 61 is hinged to the fourth hinge hole 81. Through the above hinge structure, the first connecting rod 5 and the second connecting rod 6 can rotate while respectively pushing the first transmission plate 7 and the second transmission plate 8 to move linearly in opposite directions.

[0031] Furthermore, the middle region of the first transmission plate 7 is provided with a first strip-shaped hole 72 extending along its length, and the middle region of the second transmission plate 8 is provided with a second strip-shaped hole 82 extending along its length. The turntable 3 is provided with a connecting part that is connected to the handle for transmission. In this embodiment, the connecting part is a square shaft hole 33, located in the central region of the turntable 3. One end of the square shaft passes through the second strip-shaped hole 82 of the second transmission plate 8 and is inserted into the square shaft hole 33, while the other end is fixedly connected to the handle.

[0032] A rotating boss extends from the side of the turntable 3 away from the connecting part. The rotating boss passes through the first slot 72 of the first transmission plate 7 and is rotatably connected to the inner wall of the mounting base 1. When the handle is turned, the square shaft can drive the turntable 3 to rotate. It is easy to understand that the lengths of the first slot 72 and the second slot 82 are both greater than the travel of the transmission rod 4. Therefore, during the entire travel of the transmission rod 4, the square shaft of the handle will not spatially interfere with the first transmission plate 7 and the second transmission plate 8.

[0033] When the handle is turned, the square shaft drives the turntable 3 to rotate, which in turn drives the first connecting rod 5 and the second connecting rod 6 to swing. During this process, the first connecting rod 5 pushes the first transmission plate 7 to move in the first direction, and the second connecting rod 6 pushes the second transmission plate 8 to move in the second direction. Meanwhile, the transmission rod 4 slides along the length of the slide groove 9 under the drive of the first connecting block a or the second connecting block b.

[0034] To ensure that the handle and turntable 3 return to their initial positions accurately, please refer to... Figure 5 The inner wall of the mounting base 1 is provided with a turntable limiting part 11. The peripheral edge of the turntable 3 extends outward to form a limiting protrusion 34. When the turntable 3 rotates to the set limit position, the turntable limiting part 11 and the limiting protrusion 34 interfere with each other spatially, thus stopping the turntable 3.

[0035] This embodiment also provides a door / window, including a window sash, a handle, and a transmission box 100, please refer to [reference needed]. Figure 6 The handle is installed on the left or right side frame 200 of the window sash, and the handle is connected to the turntable 3 of the transmission box 100 via a square shaft. The transmission box 100 is embedded in the frame 200 of the window sash.

[0036] In summary, the transmission box 100 of this embodiment has two sets of transmission components that can move in opposite directions. When installing doors and windows, installers can first select one of the first connecting block a or the second connecting block b to detachably connect with the transmission rod 4, depending on the specific location of the window sash to which the transmission box 100 is to be installed (i.e., the left or right side of the window sash). Then, the transmission box 100 is installed on the left or right side of the window sash. This effectively avoids the problem of the transmission box 100 not matching the application. Compared with the existing transmission boxes that can only be installed on one side of the window sash, it has a wider range of applications.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
