[0039] Please refer to Figures 1 to 9, an embodiment of the present utility model discloses a split-type transmission locking device, which includes: a transmission box assembly 1 and a locking rod assembly 2 arranged outside the transmission box assembly 1. The transmission box assembly 1 and the locking rod assembly 2 are detachably connected. The transmission box assembly 1 includes a transmission runner 12, and the locking rod assembly 2 includes a locking point 21. The transmission runner 12 is in transmission connection with the locking rod assembly 2. When the transmission runner 12 is controlled to rotate, it drives the locking point 21 to move linearly back and forth. Generally, the rotation of the transmission runner 12 is driven by a handle 4 connected thereto. It can be understood that in this embodiment, by designing the transmission box assembly 1 and the locking rod assembly 2 as a detachable structure, the installation of the transmission locking device is more convenient. At the same time, different door and window systems may require transmission locking devices of different specifications or configurations. The split-type transmission locking device in this case allows different specifications of the transmission box assembly 1 and the locking rod assembly 2 to be matched. In practical applications, the transmission box assembly 1 and the locking rod assembly 2 can be selected or customized according to different application scenarios, improving the flexibility and adaptability of the product.

[0040] In one embodiment, the transmission box assembly 1 and the locking rod assembly 2 are connected to the same profile 3 by bolts to form a detachable connection between the transmission box assembly 1 and the locking rod assembly 2. It can be understood that in this embodiment, except for the transmission connection between the transmission runner 12 and the locking rod assembly 2, there is no other direct connection relationship between the transmission box assembly 1 and the locking rod assembly 2. By connecting the transmission box assembly 1 and the locking rod assembly 2 to the same profile 3 with bolts to achieve the detachable connection between the transmission box assembly 1 and the locking rod assembly 2, while the relative positions of the transmission box assembly 1 and the locking rod assembly 2 are stable, the transmission box assembly 1 and the locking rod assembly 2 can also be separated by disconnecting the connection between the transmission box assembly 1 and the profile 3 or disconnecting the connection between the locking rod assembly 2 and the profile 3.

[0041] In another embodiment, the transmission box assembly 1 and the locking rod assembly 2 are connected to each other by bolts to form a detachable connection between the transmission box assembly 1 and the locking rod assembly 2. It can be understood that in this embodiment, the transmission box assembly 1 and the locking rod assembly 2 are directly connected by bolts, and the bolts connecting the transmission box assembly 1 and the locking rod assembly 2 can be directly operated to lock or disconnect the connection between the transmission box assembly 1 and the locking rod assembly 2.

[0042] Further, the drive box assembly 1 further includes a housing 11 and a drive rack 13. An installation cavity is provided inside the housing 11. The drive rack 13 is disposed in the installation cavity in a translatable manner, and the drive runner 12 is rotatably disposed in the installation cavity. The drive rack 13 meshes with the drive runner 12, and the drive rack 13 is in driving connection with the locking point 21. Specifically, teeth are provided on the drive runner 12, and teeth or tooth openings are provided on the drive rack 13. The teeth of the drive runner 12 mesh with the teeth or tooth openings of the drive rack 13. In this embodiment, the teeth of the drive runner 12 mesh with the teeth or tooth openings of the drive rack 13. When the handle 4 drives the drive runner 12 to rotate, the rotational movement of the drive runner 12 is converted into the translational movement of the drive rack 13 through the meshing of the teeth of the drive runner 12 with the teeth or tooth openings of the drive rack 13. The drive rack 13 then drives the locking point 21 to achieve synchronous translation, thereby controlling the opening and closing state of the locking point 21. Preferably, tooth openings are provided on the drive rack 13 in this embodiment to make the split-type drive locking device lighter in weight.

[0043] Specifically, a drive hole 112 is provided on the housing 11. The drive hole 112 communicates with the installation cavity. The handle 4 passes through the drive hole 112 and penetrates into the installation cavity to be connected to the drive runner 12. Specifically, a square hole is provided on the drive runner 12. The square shaft of the handle 4 passes through the drive hole 112 and is inserted into the square hole to be directly connected to the drive runner 12. Thus, when the handle 4 is rotated, the drive runner 12 can be directly driven to rotate, reducing the energy loss during the drive process and improving the drive efficiency.

[0044] Optionally, the housing 11 includes a front housing 114 and a rear housing 115. The above-mentioned installation cavity is formed by enclosing between the front housing 114 and the rear housing 115. Specifically, the installation cavity includes a translation notch 113 opened on the outer edge of the housing 11. Guide ribs 1131 are provided on the opposite side walls of the translation notch 113, and the guide ribs 1131 are opened along the translation trajectory of the drive rack 13. The drive rack 13 is located in the translation notch 113, and a translation slider 132 is provided on the drive rack 13. A guide groove is provided on the translation slider 132. The guide ribs 1131 are slidably connected to the guide groove, so that the drive rack 13 can perform a translational movement along a predetermined trajectory in the translation notch 113. Through the design of the slidable connection between the guide ribs 1131 and the guide groove, the precise translational movement of the drive rack 13 along the predetermined trajectory is ensured, improving the accuracy and stability of the drive.

[0045] Further, the transmission box assembly 1 further includes an anti-offset block 14. A chute is also provided on the outer shell 11, and the anti-offset block 14 is slidably installed in the chute. Specifically, screw holes for connecting handle screws are also provided on the anti-offset block 14. When assembling the handle 4 with the transmission box assembly 1, the handle screw is connected to the transmission box assembly 1 through the anti-offset block 14, and the anti-offset block 14 can slide in the chute to adjust its position, thus avoiding the problem in the prior art that the handle screw is directly connected to the outer shell 11, causing the outer shell 11 to be offset and affecting the smoothness of transmission. It can be understood that the handle 4 itself is a transmission component, and after being installed with the transmission box assembly 1, it is in transmission connection with the transmission runner 12 in the transmission box assembly 1. The installation of the handle 4 and the transmission box assembly 1 is completed through the handle base. As a fixing component, the handle base is connected to the anti-offset block 14 through the handle screw, and the handle 4 is rotatably connected to the handle base, thus completing the installation and transmission of the handle 4 and the transmission box assembly 1. Specifically, the position and connection relationship between the handle 4 and the handle base belong to the prior art and will not be elaborated here.

[0046] Further, the lock rod assembly 2 includes a movable lock piece 22. The movable lock piece 22 is connected to the transmission rack 13, and the locking point 21 is provided on the movable lock piece 22, so that the transmission rack 13 drives the locking point 21 to move. When the transmission rack 13 moves under the action of an external driving force (such as the handle 4), its movement is transmitted to the locking point 21 through the movable lock piece 22. Since there are stable connection relationships between the movable lock piece 22 and the transmission rack 13 and the locking point 21, it can ensure the synchronous movement of the transmission rack 13 and the locking point 21. This synchronous movement not only improves the locking accuracy of the transmission lock, but also enhances the overall stability and durability of the transmission lock.

[0047] Specifically, a connecting boss 131 is provided on the transmission rack 13 in the direction of the outside of the outer shell 11, and a connecting groove 221 is provided on the movable lock piece 22. The connecting boss 131 is snap-fitted into the connecting groove 221.

[0048] Further, the lock rod assembly 2 further includes a static lock piece 23. The static lock piece 23 is located on the side of the movable lock piece 22 away from the transmission box assembly 1, and the static lock piece 23 is detachably and fixedly installed together with the outer shell 11. An activity gap for the translational movement of the movable lock piece 22 is formed between the static lock piece 23 and the outer shell 11. It can be understood that the static lock piece 23, as a support structure for the movable lock piece 22, is installed on the outer shell 11 by a detachable fixing method, ensuring the firm connection between the static lock piece 23 and the outer shell 11, and being convenient for disassembly and replacement when needed. At the same time, the activity gap formed between the static lock piece 23 and the outer shell 11 provides the necessary space for the translational movement of the movable lock piece 22, ensuring the normal operation of the transmission lock.

[0049] Further, the locking point 21 is located on the side of the movable locking piece 22 facing the static locking piece 23. A limiting groove 231 is provided on the static locking piece 23. The limiting groove 231 is opened along the translation trajectory of the locking point 21, and the locking point 21 is slidably installed in the limiting groove 231. In this embodiment, the limiting groove 231 serves as the guiding structure of the locking point 21, and its shape and position are designed according to the translation trajectory of the locking point 21. When the locking point 21 is translated under the drive of the transmission rack 13 and the movable locking piece 22, its movement trajectory is strictly limited within the limiting groove 231. This guiding and limiting effect ensures that the locking point 21 can move according to the predetermined trajectory and position, thereby realizing the precise locking of the transmission lock.

[0050] Further, a first threaded hole 111 is provided on the housing 11. The first threaded hole 111 is used for passing a bolt to connect the housing 11 to the fan profile 3. A second threaded hole is provided on the static locking piece 23. The second threaded hole is used for passing a bolt to connect the static locking piece 23 to the fan profile 3;

[0051] Alternatively, a first threaded hole 111 is provided on the housing 11, and a through hole is provided on the static locking piece 23 corresponding to the first threaded hole 111. The first threaded hole 111 and the through hole are connected by a bolt.

[0052] A first threaded hole 111 is provided on the housing 11, and a through hole is provided on the static locking piece 23 corresponding to the first threaded hole 111. The static locking piece 23 and the housing 11 are connected by a bolt.

[0053] Further, a relief groove 222 is provided on the movable locking piece 22. The relief groove 222 is opened along the translation trajectory of the locking point 21. The bolt connecting the static locking piece 23 to the housing 11 and / or the fan profile 3 passes through the relief groove 222. It can be understood that by connecting the static locking piece 23 to the housing 11 and / or the fan profile 3 with bolts, the tight fixation between the static locking piece 23 and the housing 11 is realized, enhancing the stability of the connection. At the same time, the relief groove 222 provided on the movable locking piece 22 allows the bolt to pass through it, avoiding interference between the movable locking piece 22 and the bolt during the translation process of the movable locking piece 22, ensuring that the transmission lock does not malfunction or get damaged due to friction or collision between components during normal operation.

[0054] Further, the locking point 21 is an eccentric structure. The eccentric locking point 21 can generate a greater pressing force during locking, thereby improving the locking effect of the transmission lock. Moreover, the eccentric locking point 21 can also adapt to different installation environments and requirements. The position of the locking point 21 can be changed by adjusting the eccentricity of the locking point 21 to adapt to different locking positions and angles.

[0055] In an achievable assembly scenario, first assemble the drive box assembly 1 onto the sash profile 3 where the drive lock is to be installed, and then match and install the lock rod assembly 2 with the drive box assembly 1 onto the sash profile 3. Specifically, a first threaded hole 111 is provided on the outer shell 11 of the drive box assembly 1, and on the sash profile 3 where the drive lock is to be installed, there are preset a drive box connection hole corresponding to the first threaded hole 111 on the outer shell 11, and a handle clearance hole corresponding to the drive hole 112. The drive box assembly 1 is fixed to the sash profile 3 by screwing the profile connection hole and the drive box connection hole, and the handle 4 passes through the handle clearance hole and the drive hole 112 to be connected to the drive runner 12; after installing the drive box assembly 1 on the sash profile 3, align and snap the connection slot 221 on the moving lock piece 22 in the lock rod assembly 2 with the connection boss 131 on the drive rack 13 in the drive box assembly 1, and then install the static lock piece 23 on the sash profile 3 with bolts as well. Thus, the installation of the drive box assembly 1 and the sash profile 3, the connection of the drive box assembly 1 and the lock rod assembly 2, and the installation of the lock rod assembly 2 and the sash profile 3 are completed. Specifically, on the sash profile 3, there is also preset a through hole corresponding to the anti-pull deviation block 14, and the handle screw passes through the through hole to connect the anti-pull deviation block 14 with the handle base. When the anti-pull deviation block 14 is pulled out to abut against the sash profile 3, the installation of the handle base is completed. It should be noted that the handle base is connected to the sash profile 3 and the anti-pull deviation block 14 by handle screws, and the handle 4 is installed on the handle base and its square shaft passes through the drive hole 112 to be connected to the drive runner 12.

[0056] In another achievable assembly scenario, first assemble the drive box assembly 1 and the lock rod assembly 2 into a whole, and then assemble the lock rod assembly 2 in this whole onto the sash profile 3 where the drive lock is to be installed, saving on-site assembly time, being suitable for large-scale installation of the same specifications, having higher efficiency and more stable installation effects. Specifically, use bolts to connect the first threaded hole 111 on the outer shell 11 in the drive box assembly 1 and the through hole on the static lock piece 23 in the lock rod assembly 2, so that the drive box assembly 1 and the lock rod assembly 2 become a whole.

[0057] Compared with the prior art, the split-type drive lock of the present utility model decomposes the drive lock into a drive box assembly and a lock rod assembly that are detachably connected. The drive runner in the drive box assembly converts the rotational movement of the handle into the translational movement of the lock point through the gear transmission principle, and then completes the locking function of the doors and windows. Through the split-type design, the integration and decomposition of functions are realized. The drive box assemblies and lock rod assemblies of different specifications can be disassembled and assembled according to actual needs to adapt to sash profiles of different cavity specifications, reducing inventory costs and the occupation of storage space, and improving production efficiency and economic benefits.

[0058] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present utility model.
