Description

Technical Field

[0001] The utility model relates to the technical field of door and window hardware, and particularly relates to a combined transmission box and a door and window thereof. Background Art

[0002] The transmission box is a key component that converts the rotation of the door and window handle into the movement of the transmission rod. In a common transmission box, the core functional component is a gear and rack mechanism. Among them, the door and window handle is inserted into the gear 01 to drive the gear 01 to rotate, and the rack 02 meshes with the gear 01. When the gear 01 rotates, the rack 02 as the transmission rod can move left and right, as Figure 1 shown.

[0003] The door and window handle 03 includes a handle with a base and a handle without a base. The transmission box must be respectively provided with an installation hole adapted to the handle with a base and an installation hole adapted to the handle without a base. The pitch diameter of the gear 01 of the transmission box usually interferes with the fixing screw 031 of the handle without a base, as Figure 2 shown. Therefore, the length of the fixing screw of the handle without a base needs to be strictly controlled. When it is too long, it will interfere with the gear 01. When it is too short, it cannot be connected to the anti-pull deviation block of the transmission box. Due to the variety of profiles, the installation efficiency will be affected during actual use.

[0038] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0039] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model; the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance; in addition, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected" 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 directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meaning of the terms in the present utility model can be understood according to specific circumstances.

[0040] See Figure 3, the present utility model discloses a door and window, including a door and window profile 2, a handle 3, door and window hardware (not shown in the figure), and a combined drive box 1. The combined drive box 1 is arranged inside the door and window profile 2. The drive input end of the combined drive box 1 is connected to the handle 3, and the output end of the combined drive box 1 is connected to the door and window hardware. The combined drive box 1 transmits the rotational force of the handle 3 to the door and window hardware to control functions such as the opening and closing of the door and window.

[0041] See Figure 4 , Figures 9 - 12 , the combined drive box 1 includes a drive box body 10, a first-stage drive member 20, a drive rod 30, and a second-stage drive member 40. Inside the drive box body 10, there is a first mounting hole 101 for mounting a handle 3 without a base and a second mounting hole 102 for mounting a handle 3 with a base; the first-stage drive member 20 is connected to the handle 3 and is used to receive the rotational force of the handle 3; the drive rod 30 can move relative to the window frame to drive the door and window hardware; one end of the second-stage drive member 40 is connected to the first-stage drive member 20, and the other end of the second-stage drive member 40 is connected to the drive rod 30, which is used to convert the rotational force of the first-stage drive member 20 into a force to drive the drive rod 30 to translate; both the first-stage drive member 20 and the second-stage drive member 40 are arranged inside the drive box body 10, and the rotational trajectories of the first-stage drive member 20 and the second-stage drive member 40 do not interfere with the positions of the first mounting hole 101 and the second mounting hole 102.

[0042] The combined drive box 1 of this solution drives the drive rod 30 in stages through the first-stage drive member 20 and the second-stage drive member 40, replacing the existing gear and rack structure, enabling the first-stage drive member 20 and the second-stage drive member 40 to avoid the positions of the first mounting hole 101 and the second mounting hole 102 at the same time. When installing the handle 3, there is no need to accurately calculate and cut the mounting screws 301 of the handle 3, greatly improving the installation efficiency and avoiding the risk of interfering gears.

[0043] It should be noted that for the existing 180-degree drive box, when the drive distance is satisfied, the size cannot adapt to extremely narrow profiles and needs to be milled through. Through the staged drive of the first-stage drive member 20 and the second-stage drive member 40 in this solution, the outer diameter size of the first-stage drive member 20 can be reduced, and the overall height h of the drive box can be reduced (it can be reduced to within 21 mm on the basis of the existing 26 mm) without milling through when used for narrow-edge profiles.

[0044] See Figures 5 - 6, the first - stage transmission member 20 includes a handle transmission part 21 and a driving gear 22. One end of the second - stage transmission member 40 is provided with an arc rack 41. The handle transmission part 21 is used to connect with the handle 3 to drive the driving gear 22 to rotate self - rotatably. The driving gear 22 meshes with the arc rack 41 to drive the arc rack 41 to rotate. The handle transmission part 21 is provided with a square hole 211 for passing through the rotating end of the handle 3, so as to drive the driving gear 22 to rotate self - rotatably when the handle 3 rotates.

[0045] See Figures 6 - 7 , the surface of the arc rack 41 in contact with the transmission box body 10 is provided with a first arc sliding part 411, and a second arc sliding part 103 is arranged in the transmission box body 10. The first arc sliding part 411 is slidably connected with the second arc sliding part 103 to limit the sliding track of the arc rack 41. Specifically, the first arc sliding part 411 is an arc chute, and the second arc sliding part 103 is an arc slide rail. It can be understood that when the handle 3 is in the initial installation state, the arc rack 41 is in the middle position of the arc slide rail; if the handle 3 rotates clockwise by 90 degrees, the arc rack 41 rotates to one end of the arc slide rail; if the handle 3 rotates counterclockwise by 90 degrees, the arc rack 41 rotates to the other end of the arc slide rail.

[0046] In this embodiment, the first mounting hole 101 is arranged inside the second arc sliding part 103, and the second mounting hole 102 is arranged outside the second arc sliding part 103. Both the first mounting hole 101 and the second mounting hole 102 include two, and are symmetrically arranged on both sides of the first - stage transmission member 20 with the first - stage transmission member 20 as the center. When the arc rack 41 rotates to one end or the other end of the arc slide rail, the first mounting hole 101 is inside the arc rack 41, the second mounting hole 102 is outside the arc rack 41, and neither the first mounting hole 101 nor the second mounting hole 102 interferes with the arc rack 41.

[0047] See Figure 8 , the other end of the second - stage transmission member 40 is provided with a rotating transmission part 42, and the transmission rod 30 is provided with a translation transmission part 31. The rotating transmission part 42 is connected with the translation transmission part 31 to drive the translation transmission part 31 to translate when the rotating transmission part 42 rotates. It should be noted that the rotating transmission part 42 is used to transmit the rotating force to the translation transmission part 31 to form the force for driving the translation transmission part 31 to translate. The specific structure of the rotating transmission part 42 and the translation transmission part 31 can have various connection forms, such as wedge - shaped contact connection or gear - rack connection.

[0048] In this embodiment, the rotating transmission part 42 is a fork structure, and the translation transmission part 31 is an auxiliary roller. The auxiliary roller 31 is slidably matched with the middle groove 421 of the fork structure. When the second - stage transmission member 40 rotates, the auxiliary roller 31 slides along the middle groove 421 to drive the transmission rod 30 to translate.

[0049] Specifically, the auxiliary roller includes a rotating shaft 311, a roller sleeve 312, and an ear seat 313. The ear seat 313 is provided on the transmission rod 30. The two ends of the rotating shaft 311 are respectively connected to the ear seat 313. The roller sleeve 312 is sleeved outside the rotating shaft 31, and the roller sleeve 312 is in contact with the middle groove 421 of the fork structure.

[0050] In this embodiment, the transmission box body 10 includes a panel 11, a bottom shell 12, and a face shell 13. The transmission rod 30 is slidably connected inside the panel 11. The bottom shell 12 and the face shell 13 enclose a cavity for accommodating the first-stage transmission member 20 and the second-stage transmission member 40. Corresponding first mounting holes 101, second mounting holes 102, second arc-shaped sliding portions 103, and driving holes 104 are provided on the bottom shell 12 and the face shell 13. The driving hole 104 faces the first-stage transmission member 20. The first mounting hole 101 is used to insert the screw 301 of the handle 3 without a base, and the second mounting hole 102 is used to insert the screw 301 of the handle 3 with a base. The driving hole 104 faces the square hole 211 of the handle transmission portion 21 and is used to insert the rotating end of the handle 3. When installing the transmission box body 10, part of the face shell 13 and the bottom shell 12 are inserted into the profile along the side of the door and window profile 2, and the panel 11 seals the side of the door and window profile 2. The handle 3 is inserted between the face shell 13 and the bottom shell 12 from the outer surface or the inner surface of the door and window profile for transmission.

[0051] In this embodiment, the combined transmission box 1 further includes a box body fixing component 50. The box body fixing component 50 includes a clamping piece 51, a fixing connecting piece 52, and an elastic piece 53. The panel 11 is provided with a fixing hole 111 through which the fixing connecting piece 52 passes. The transmission rod 30 is provided with a strip-shaped through hole 33 through which the fixing connecting piece 52 passes. The fixing connecting piece 52 sequentially passes through the fixing hole 111, the strip-shaped through hole 33, and the elastic piece 53 and is connected to the clamping piece 51. The width of the clamping piece 51 is greater than the width of the strip-shaped through hole 33 and is used to clamp the window frame to fix the transmission box body. The elastic piece 53 is provided between the clamping piece 51 and the transmission rod 30 and is used to limit the random swing of the clamping piece 51 and abut against the transmission rod 30 to reduce the gap between the transmission rod 30 and the side groove of the profile, facilitating installation.

[0052] In this embodiment, the combined transmission box 1 further includes an anti-offset block 60. The anti-offset block 60 is inserted through the bottom shell 12 and / or the face shell 13. The anti-offset block 60 is provided with positioning holes corresponding to the first mounting hole 101 and the second mounting hole 102 respectively and is used to fix the handle 3 when installing the handle 3. When installing the handle 3, the screw 301 of the handle 3 pulls the anti-offset block 60 out of the transmission shell and presses against the surface of the profile. The base of the handle 3 and the anti-offset block 60 clamp the profile to fix the handle 3.

[0053] The above embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
