[0002] At present, most of the existing two-way lock boxes and handle connection components are relatively large. When the component that needs to cooperate with the window handle is extremely narrow, due to space problems, the two-way transmission component is difficult to cooperate with some narrow profiles. Therefore, it is necessary to redesign the overall structure of the existing two-way transmission component so that it can be applied to extremely narrow window handle installation profiles. Summary of the Invention

[0003] In order to solve certain technical problems existing in the prior art, the purpose of this application is to provide an extremely narrow bidirectional transmission component, which can solve the problem that the component connecting the bidirectional lock box and the handle is large and is not suitable for extremely narrow profiles. It has a compact internal structure, high reliability during operation, long service life, and high transmission accuracy.

[0004] To solve the above existing technical problems, this application adopts the following technical solutions:

[0007] Preferably, the first rack is arranged at one end of the first transmission plate and extends toward the second transmission plate. The second transmission plate is provided with an inwardly recessed groove. The second rack is located on one side of the groove. The transmission gear and the first rack are both located in the groove.

[0008] Preferably, a first elongated hole for allowing the driving rod to extend outward and two second elongated holes for allowing the transmission rod to extend outward are provided in the middle of the base plate, a first positioning hole matching the first elongated hole is provided on the first transmission plate, and a second positioning hole matching the second elongated hole is provided on the first transmission plate and the second transmission plate respectively, one end of the driving rod is fixed in the first positioning hole, and one end of the transmission rod is fixed in the second positioning hole.

[0009] Preferably, the transmission rod and the driving rod both adopt a rivet structure.

[0022] like Figure 1 and Figure 2As shown, an extremely narrow bidirectional transmission component includes a long strip lock box 17 with openings at both ends consisting of a U-shaped cover 10 and a bottom plate 4, and plugs 7 are provided at both ends of the lock box 17. A mounting cavity with openings at both ends is formed inside the lock box 17, and a sheet-like first transmission plate 13 and a second transmission plate 19 are provided inside the lock box 17. A meshing linkage mechanism 24 is provided between the first transmission plate 13 and the second transmission plate 19, and the first transmission plate 13 is provided with a driving rod 1 protruding toward the outside of the bottom plate 4. The first transmission plate 13 and the second transmission plate 19 are both provided with a transmission rod 22 protruding toward the outside of the bottom plate 4. The first transmission plate 13 equipped with the transmission rod 22 slides horizontally left and right along the cavity through the driving rod 1, and is controlled in linkage with the second transmission plate 19 through the meshing linkage mechanism 24. The second transmission plate 19 equipped with the transmission rod 22 is reversed by the meshing linkage mechanism 24 to achieve reverse synchronous left and right sliding with the first transmission plate 13.

[0023] During the actual assembly process, the window handle is mounted on the drive rod 1, while the transmission rods 22 on either side are connected to external mechanisms. When the transmission rods 22 on either side need to be moved, the handle drives the drive rod 1 to move laterally along the lock box 17. This lateral movement of the drive rod 1 causes the first transmission plate 13 to slide laterally in synchronism. The second transmission plate 19, in turn, drives the meshing linkage mechanism 24 through the first transmission plate 13 to achieve relatively opposite lateral, bidirectional reciprocating motion, thereby achieving synchronous, relative left and right movement of the two transmission rods 22. Because the first and second transmission plates 13 and 19 are sheet-like structures and are linked by the meshing linkage mechanism 24, they can achieve stable relative drive while being smaller, making the lock box 17 smaller. This solves the problem of the existing bidirectional lock box 17 being unsuitable for extremely narrow profiles due to the large components connecting the handle and the handle. The meshing connection also makes the internal structure compact, highly reliable during operation, has a long service life, and high transmission accuracy.

[0024] Further improved, the meshing linkage mechanism 24 includes a first rack 25 provided on one side of the first transmission plate 13, a second rack 18 provided on one side of the second transmission plate 19, and a transmission gear 16 provided between the first rack 25 and the second rack 18. A second rivet 15 is provided between the transmission gear 16 and the lock box 17, and the transmission gear 16 rotates around the second rivet 15 as a rotating axis.

[0025] Racks are formed on both the first transmission plate 13 and the second transmission plate 19, and the two racks are connected by a transmission gear 16, which can make the overall thickness of the lock box 17 flatter, and the transmission gear 16 is fixed in the lock box 17 by the second rivet 15. When the first rack 25 drives the transmission gear 16 to rotate with the second rivet 15 as the axis during the sliding process, the second rack 18 on the other side can be driven by the transmission gear 16 to slide in the opposite direction. While ensuring the rigidity of each transmission component, the overall thickness can be minimized compared to other linkage structures, which effectively solves the problem of the existing lock box 17 being installed on an extremely narrow profile due to the inability to reduce the thickness of the internal transmission components.

[0026] A further improvement is that the first rack 25 is arranged at one end of the first transmission plate 13 and extends toward the second transmission plate 19, the second transmission plate 19 is provided with an inwardly recessed groove 23, the second rack 18 is located on one side of the groove 23, and the transmission gear 16 and the first rack 25 are both located in the groove 23.

[0027] By forming an inwardly recessed groove 23 on the second transmission plate 19, the second rack 18 is located on one side of the groove 23, and the transmission gear 16 and the first rack 25 are both located in the groove 23, so that the meshing linkage mechanism 24 will not increase the overall width of the lock box 17 after installation, thereby making the width of the lock box 17 narrower, so that the lock box 17 can be installed on extremely narrow profiles.

[0028] A further improvement is that a first elongated hole 2 for allowing the drive rod 1 to extend outward and two second elongated holes 21 for allowing the transmission rod 22 to extend outward are provided in the middle of the base plate 4, a first positioning hole 14 matching the first elongated hole 2 is provided on the first transmission plate 13, and a second positioning hole 20 matching the second elongated hole 21 is provided on each of the first transmission plate 13 and the second transmission plate 19, one end of the drive rod 1 is fixed in the first positioning hole 14, and one end of the transmission rod 22 is fixed in the second positioning hole 20.

[0029] The first elongated hole 2 and the second elongated hole 21 can play a limiting and guiding role. The transmission of the components is driven by the handle to drive the driving rod 1 to move horizontally along the first elongated hole 2, and the transmission rod 22 moves left and right along the second elongated hole 21 synchronously. The movement trajectory is more precise and the overall structure is simpler. It is more convenient to fix and move the transmission rod 22 and the driving rod 1, and it can also effectively reduce the overall weight.

[0030] As a further improvement, both the transmission rod 22 and the driving rod 1 adopt a rivet structure, which has a simple structure, is easy to operate, and has higher firmness after installation.

[0031] Further improvements are as follows: each of the first transmission plate 13 and the second transmission plate 19 is provided with a long waist hole 8, a limiting ring 9 is provided in the waist hole 8, a first rivet 12 is provided between the limiting ring 9 and the box body, and the first transmission plate 13 and the second transmission plate 19 slide along the limiting ring 9; the lock box 17 is provided with a clamping block 3 and a screw 11, and the U-shaped surface cover 10 and the bottom plate 4 are fixed by the clamping block 3 and the screw 11, and the screw 11 passes through the waist hole 8 and is connected to the clamping block 3.

[0032] The waist hole 8 design effectively reduces the overall weight. At the same time, the retaining ring 9 is fixed to the waist hole 8 within the box body via the first rivet 12, allowing the first transmission plate 13 and the second transmission plate 19 to slide based on the retaining ring 9 when sliding, improving sliding flexibility and making the installation of the first transmission plate 13 and the second transmission plate 19 more flexible. They no longer come into contact with the side walls, resulting in a more precise sliding trajectory. Furthermore, the waist hole 8 design facilitates the installation of the lock box 17 via the screws 11 and the clamping block 3. After installation, this design does not affect the lateral sliding of the first transmission plate 13 and the second transmission plate 19, making the accessories more versatile.

[0033] A further improvement is that one end of the groove 23 passes through the waist hole 8.

[0034] By connecting one end of the groove 23 with the waist hole 8, the depth of the first rack 25 can be increased while shortening the length of the groove 23, and the overall length of the first transmission plate 13 and the second transmission plate 19 can be effectively shortened, thereby making the overall length of the lock box 17 shorter and the overall volume of the entire two-way transmission component smaller.

[0035] As a further improvement, two pin holes 5 are respectively provided at both ends of the base plate 4, and a pin shaft 6 is provided on the plug 7 to cooperate with the pin hole 5. After the plug 7 is inserted into the lock box 17, the pin shaft 6 is inserted into the pin hole 5 for fixation.

[0036] The plug 7 is made of plastic. When it is inserted into both ends of the lock box 17, the pin 6 moves to the pin hole 5 and can be automatically inserted, thereby avoiding the phenomenon of falling off during practical use.

[0037] The above-mentioned embodiments are only preferred embodiments of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and replacements made by technicians in this field based on the present application shall fall within the scope of protection required by the present application.
