DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0022] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0023] like Figures 1 to 7 The split-axis dial wheel quick-open lock cylinder shown in the figure comprises a lock housing 1, a lock tongue 2, a lock frame 3 and a dial wheel assembly, wherein the lock tongue 2 is connected to the lock frame 3, and the dial wheel assembly is linked to the lock frame 3. Operating the dial wheel assembly can make the lock frame 3 drive the lock tongue 2 to slide backward into the lock housing 1, and the dial wheel assembly comprises a first dial wheel 4 and a second dial wheel 5 that rotate and are limited in the lock housing 1, and the first dial wheel 4 and the second dial wheel 5 are respectively provided with a first square shaft 6 and a second square shaft 7 for driving their respective rotations, and the first square shaft 6 and the second square shaft 7 are coaxially arranged and rotated in cooperation with each other.

[0024] By setting two sets of dial wheels, the rotation of the inner handle and the outer handle can be controlled separately. When the inner handle rotates, the outer handle will not rotate synchronously, which meets the needs of some users. During assembly, the first dial wheel 4 and the second dial wheel 5 are fixed to the inner ends of the first square shaft 6 and the second square shaft 7. The first square shaft 6 and the second square shaft 7 are plugged in to complete the assembly of the dial wheel assembly, thereby realizing separate control and more flexible operation.

[0025] The double dial wheel design of the present application can also be applied to the following scenarios: the traditional lock core adopts a square shaft, and the inner and outer door handles are fixed at both ends of the square shaft, and the two realize synchronous rotation. When the inner door handle is locked, the outer door handle cannot be rotated, and it is necessary to operate the locking mechanism inside the door (this is the prior art) to unlock the door before the handle can be rotated. The locking mechanism can be set to lock the outer door handle, so that the outer door handle cannot be rotated, while the inner door handle can still be rotated. The inner door handle is linked with the locking mechanism, and the outer door handle can be unlocked while the inner door handle is rotated. This is a conventional unlocking method in the prior art. The combined structure of the double dial wheels of the present application is suitable for this scenario, and the operation is more flexible.

[0026] The first dial wheel 4 and the second dial wheel 5 are respectively located at the inner ends of the first square shaft 6 and the second square shaft 7 and the two are in contact with each other. Blocking parts 8 are provided on the first square shaft 6 and the second square shaft 7. The two blocking parts 8 are respectively located on the opposite sides of the first dial wheel 4 and the second dial wheel 5 to prevent the first dial wheel 4 and the second dial wheel 5 from slipping. The assembly is stable and reliable. The blocking part 8 in this embodiment can be spherical or rectangular, etc.

[0027] The first dial 4 is provided with a first rotating part 9, the second dial 5 is provided with a second rotating part 10, the first rotating part 9 is provided with a socket 11, the second rotating part 10 is provided with a plug-in column 12 rotatably matched with the socket 11, the plug-in column 12 is rotatably matched with the socket 11, and the end face of the first rotating part 9 is in contact with the end face of the second rotating part 10. In this embodiment, the first rotating part 9 and the second rotating part 10 are preferably rotating bodies.

[0028] The lock frame 3 is provided with a long groove 13 along its sliding direction, the first dial wheel 4 and the second dial wheel 5 extend into the long groove 13 to form a paddle 14, the inner wall of the rear end of the long groove 13 has a contact surface 15 that cooperates with the paddle 14, the paddle 14 contacts the contact surface 15 of the long groove 13, and the rotation of the dial wheel can make the lock frame 3 drive the lock tongue 2 to slide backward into the lock shell 1. The long groove 13 can be provided on any one side or both sides of the lock frame 3 at the same time, and the design is based on actual conditions.

[0029] The lock tongue 2 includes a lock piece 16 and a lock head 17 fixed or integrally connected to the lock frame 3. The front end opening of the lock head 17 is formed with a receiving groove, and a magnetic member (not shown in the figure) is installed in the receiving groove.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only preferred examples of the utility model, and are not used to limit the utility model.
