[0030] See Figure 1 , Figure 2 This embodiment discloses a novel lock body knob connection assembly, including an inner knob 1 and an outer knob 2. A lock cylinder transmission component 3 connects the inner knob 1 and the outer knob 2. The inner knob 1 is connected to the door body via an inner panel 4, and the outer knob 2 is connected to the door body via an outer panel 5. The inner panel 4 and the outer panel 5 are connected by long screws. The inner knob 1 and the outer knob 2 can be linked together via the lock cylinder transmission component 3, and the bolt can be controlled by the transmission of the lock cylinder transmission component 3. The cooperation between the lock cylinder transmission component 3 and the bolt is prior art, and this embodiment will not elaborate on this structure.

[0031] Specifically, such as Figure 3 As shown, the inner knob 1 includes an inner rotating handle 11 and an inner rotating connecting part 12 integrally connected to the inner rotating handle 11. Rotating the inner rotating handle 11 can drive the inner rotating connecting part 12 to rotate. The inner panel 4 has a through hole in the center, and the inner rotating connecting part 12 passes through the through hole.

[0032] The inner rotating connection part 12 further includes an inner rotating base 121 integrally connected to the inner rotating handle 11, an inner rotating support leg 122 integrally connected to the inner rotating base 121, and a first extended connector 124 connected to the inner rotating support leg 122.

[0033] The inner rotating base 121 is constructed in a cylindrical shape, with a circumferentially arranged slot 123 for mounting a retaining spring to secure the inner knob 1 to the inner panel 4. The inner rotating support leg 122 is constructed as an arc-shaped plate structure and is provided in four sets, evenly spaced along the bottom circumference of the inner rotating base 121. The first extended connector 124 is detachably connected between the inner rotating support leg 122 and the lock cylinder transmission member 3, the structure of which will be described below.

[0034] Combination Figure 2 and Figure 7 The outer knob 2 includes an outer rotating plate 21 and an outer rotating connecting part 22 integrally connected to the outer rotating plate 21. The outer rotating plate 21 is constructed as a circular plate, and its outer surface is provided with an elongated recessed groove 211. By inserting a coin or other flat object adapted to the recessed groove 211 into the recessed groove 211, the outer rotating plate 21 can be rotated. The outer panel 5 has a through hole in the center, and the outer rotating connecting part 22 passes through the through hole.

[0035] The outer rotating connection part 22 further includes an outer rotating base 221 integrally connected to the outer rotating plate 21, an outer rotating snap-fit ​​body 222 integrally connected to the outer rotating base 221, and a second extended connector 223 connected to the outer rotating snap-fit ​​body 222.

[0036] The outer rotating base 221 is constructed in a cylindrical shape, and a slot 123 is also provided in its circumference for mounting a retaining spring to fix the outer knob 2 to the outer panel 5. The outer rotating locking body 222 is constructed in a cross-shaped column, and the second extended connector 223 is detachably connected between the outer rotating locking body 222 and the lock cylinder transmission member 3, the structure of which will be described below.

[0037] See Figure 6 The lock cylinder transmission component 3 includes a snap-fit ​​part 31 that cooperates with the first extended connector 124 and the second extended connector 223. The snap-fit ​​part 31 is constructed in a ring shape, and four sets of baffles 32 are fixedly provided on its inner wall at intervals.

[0038] See Figure 4 , Figure 5 The first extended connector 124 includes a first connecting base post 1241 that is generally cylindrical. The first connecting base post 1241 has four sets of insertion slots 1242 on the side facing the inward rotating leg 122, corresponding to the orientation of the inward rotating leg 122. The first connecting base post 1241 has a first connecting protrusion 1243 on the side facing the lock cylinder transmission member 3, which matches the structure of the internal partition block 32 of the locking part 31. During installation, the first extended connector 124 is inserted into the locking part 31 of the lock cylinder transmission member 3, and then the inward rotating leg 122 is inserted into the insertion slots 1242. Then, rotating the inward rotating handle 11 will drive the first extended connector 124 and the lock cylinder transmission member 3 to rotate.

[0039] See Figure 8 , Figure 9 and combined Figure 7 The second extended connector 223 includes a second connecting base post 2231 constructed as a cylinder, a connecting groove 2232 disposed on one end face, and a second connecting protrusion 2233 disposed on the other end face. In this embodiment, the connecting groove 2232 is configured to match the cross-shaped external rotating snap-fit ​​body 222, and the second connecting protrusion 2233 is configured to correspond to the first connecting protrusion 1243 and match the snap-fit ​​portion 31. During installation, the second extended connector 223 is inserted into the snap-fit ​​portion 31 of the lock cylinder transmission member 3, and then the external rotating snap-fit ​​body 222 is inserted into the connecting groove 2232.

[0040] The first connecting base column 1241 and the second connecting base column 2231 are respectively provided with mounting holes 6 at their axial centers. By installing screws in the mounting holes 6, both can be fixed to the lock core transmission component 3.

[0041] The lock body knob of this embodiment can adapt to door bodies of different thicknesses by means of the detachable first extended connector 124 and the second extended connector 223. Specifically, when the first extended connector 124 and the second extended connector 223 are installed, the inner rotating support leg 122 and the outer rotating locking body 222 of the inner and outer knobs do not directly contact the lock cylinder transmission component 3, but are driven through the two extended connectors. This structure can increase the distance between the inner panel 4 and the outer panel 5, thereby adapting to thicker door bodies. When the first extended connector 124 and the second extended connector 223 are removed, the inner rotating support leg 122 and the outer rotating locking body 222 of the inner and outer knobs move closer to each other and act directly on the lock cylinder transmission component 3. This structure reduces the distance between the inner panel 4 and the outer panel 5, thereby adapting to thinner door bodies.

[0042] Furthermore, to achieve direct driving of the lock cylinder transmission component 3 by the inner rotating support leg 122 and the outer rotating locking body 222, in this embodiment, the gap between adjacent spacers 32 of the locking part 31 matches the structure of the inner rotating support leg 122. When the first extended connector 124 and the second extended connector 223 are not installed, the four sets of inner rotating support legs 122 can be inserted between the spacers 32, and the arc-shaped plate structure of the inner rotating support leg 122 allows it to fit against the inner wall of the locking part 31. By rotating the inner knob 1, the lock cylinder transmission component 3 can be driven to rotate.

[0043] Furthermore, at least two sets of partition blocks 32 are configured as right-angled sectors, and these two sets of partition blocks 32 are arranged opposite to each other. The cross-shaped outer rotating locking body 222 can extend into the locking part 31. The right-angled sector-shaped partition blocks 32 abut against the cross-shaped right-angled outer wall of the outer rotating locking body 222. By rotating the outer knob 2, the lock cylinder transmission component 3 can be driven to rotate. It can be understood that by rotating the outer knob 2, the lock cylinder transmission component 3 is driven to rotate, and due to the cooperation of the partition blocks 32 and the inner rotating support leg 122, the inner knob 1 can be further driven to rotate, and vice versa.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
