Description

Technical Field

[0001] This utility model relates to the field of door and window hardware technology, specifically to a door and window lock transmission device. Background Technology

[0002] Among commonly used door and window locks, the transmission box is the most frequently used component. Typically, transmission boxes use external force to control the movement of gears within the box, moving them left or right to open and close the door or window. In existing transmission boxes, the gears and the latch are all mounted on the same structure. Since either the gear or the latch is the most vulnerable part of the transmission box, if either component fails, the entire component needs to be disassembled and replaced, resulting in waste. Furthermore, to ensure structural strength, current window lock transmission gear boxes on the market require a large amount of zinc, leading to higher zinc consumption and production costs.

[0005] In this technical solution, since the drive gear meshes with the drive bar, when the drive gear is inserted into the door / window square bar and the drive gear is rotated, the drive bar can slide along its length, allowing the eccentric cam structure to slide into the lock groove of the door / window locking position. By controlling the position of the eccentric cam, quick unlocking and locking can be achieved, making the operation convenient and fast. At the same time, the drive gear is fixed to the inside of the mounting panel through the mounting mechanism, which can improve the stability of the drive gear installation and the overall structural strength, making the whole device more durable.

[0006] Preferably, the mounting mechanism includes a pair of oppositely arranged cover plates, forming an mounting space between the two cover plates, and support feet connected to both ends of the cover plates, with the lower ends of the support feet fixedly connected to the inner surface of the mounting panel.

[0007] Preferably, the cover plate is provided with an insertion hole that is directly opposite to the drive square hole.

[0008] Preferably, the upper end of the support leg is provided with a mounting part, which is fixed to the mounting positions located on both sides of the mounting space.

[0009] Preferably, the gear, cover plate, and support foot are assembled using a spin riveting or press riveting process.

[0010] Preferably, the support foot is made of zinc material, and the cover plate and gear are made of iron material.

[0011] Preferably, the drive bar has clearance grooves at the mounting positions of the two support legs for the support legs to pass through.

[0019] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0020] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0021] Example 1

[0022] like Figures 1 to 3 As shown in the figure, a specific embodiment of this utility model provides a door and window lock transmission device. This device has higher structural strength, is more durable, and is easy to operate. Specifically, it includes a mounting panel 100, on which a transmission component is provided. The transmission component includes a drive gear 200 and a drive bar 300 meshing with the drive gear 200. The drive gear 200 is provided with a drive square hole 210. The drive bar 300 slides in cooperation with the inner surface of the mounting panel 100. The outer surface of the mounting panel 100 is provided with eccentric cams 400 arranged at intervals, and the eccentric cams 400 are connected to the drive bar 300. The inner surface of the mounting panel 100 is provided with a mounting mechanism for mounting the drive gear 200.

[0023] like Figures 1 to 3 As shown, with the above configuration, since the drive gear 200 meshes with the drive bar 300, when the drive gear 200 is inserted into the door / window square bar and rotates, the drive bar 300 can slide along its length, allowing the eccentric cam 400 to slide into the lock groove of the door / window locking position. By controlling the position of the eccentric cam 400, quick unlocking and locking can be achieved, making the operation convenient and fast. At the same time, the drive gear 200 is fixed to the inside of the mounting panel 100 through the mounting mechanism, which can improve the stability of the drive gear 200 installation and the overall structural strength, making the entire device more durable. The drive gear can be a half-width gear, and the drive bar 300 can be linked with the drive gear by setting a toothed groove structure.

[0024] like Figure 3 As shown, since the drive bar 300 needs to be connected to the eccentric cam 400, the eccentric cam 400 can move with the drive bar 300 to achieve unlocking and locking. The eccentric cam 400 has a connecting part, and the drive bar 300 is provided with a connecting port corresponding to the installation position of each eccentric cam 400. Therefore, the connecting part of the eccentric cam 400 can be fixedly connected to the connecting port of the drive bar 300 after passing through the mounting panel 100. Usually, a riveting process is used for assembly to ensure that the eccentric cam 400 is linked with the drive bar 300. Since the connecting part of the eccentric cam 400 needs to pass through the mounting panel 100, the mounting panel 100 is also provided with a strip groove corresponding to the installation position of the eccentric cam 400.

[0025] Example 2

[0026] like Figures 1 to 3 As shown, this embodiment provides a mounting mechanism for installing the drive gear 200. The mounting mechanism specifically includes a pair of oppositely arranged cover plates 500, forming an installation space between the two cover plates 500. Support legs 600 are connected to both ends of the cover plates 500, and the lower ends of the support legs 600 are fixedly connected to the inner surface of the mounting panel 100. Thus, the drive gear 200 can be rotatably installed in the installation space via the cover plates 500, while being fixed to the inner side of the mounting panel 100 via the support legs 600. Since the drive gear 200 needs to be driven to rotate using a structure such as a shaft, this embodiment provides insertion holes 510 on the cover plates 500 that are directly opposite the drive square hole 210. Door and window strips can be inserted through the insertion holes 510 and connected to the drive gear 200 for rotation. Furthermore, the drive strip 300 has clearance grooves 310 corresponding to the installation positions of the two support legs 600, allowing the support legs 600 to pass through. The clearance grooves 310 fix the support legs 600 while ensuring that the drive strip 300 can slide under the drive of the gear structure.

[0027] like Figure 1 and Figure 2 As shown, in this embodiment, a mounting part 610 is provided at the upper end of the support foot 600. The mounting part 610 is fixed on the mounting positions located on both sides of the mounting space, and the support foot 600 can be fixed on both sides of the mounting space. In specific assembly, the gear, cover plate 500, and support foot 600 are assembled using a riveting or press-fitting process. In addition, in practical applications, the support foot 600 is made of zinc material, while the cover plate 500 and gear are made of iron material. In this way, the amount of zinc alloy material used can be reduced during production, thereby reducing production costs and improving product strength. The torque of similar products on the market is increased from 25 N·m to 50 N·m, effectively improving product quality. In practical applications, this device is suitable for door edge distance specifications of 20-22 cm. At the same time, for different usage scenarios, those skilled in the art can adapt to various window specifications by replacing the mounting panel 100 and drive bar 300 of different lengths, and by adjusting the number of eccentric cams 400, thus having a wide range of applications and improving the practicality of this device.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
