Manual and electric lock cylinder switch mechanism

Abstract

The invention discloses a manual and electric lock cylinder switching mechanism. The manual and electric lock cylinder switching mechanism comprises a shell and a motor. A threaded shaft is fixed on an output shaft of the motor. A transmission assembly is assembled on the threaded shaft and comprises a lock cylinder flange, a sliding nut, a sliding nut guide rod and a transmission gear. The lock cylinder flange is matched with the threaded shaft through a first rolling bearing. The transmission gear is matched with the threaded shaft through a second rolling bearing. The sliding nut guide rod is transversely placed between the lock cylinder flange and the transmission gear. The sliding nut is arranged on the sliding nut guide rod in a penetrating mode and is in threaded connection with the threaded shaft. A flange bump is arranged on the inner side of the lock cylinder flange, a gear bump is arranged on the inner side of the transmission gear, and limiting bumps are arranged on the two sides of the sliding nut respectively. The motor is sleeved with a rotating handle. Gear teeth are arranged on the inner side of the rotating handle and are in transmission fit with the transmission gear through a gear shaft. The manual and electric lock cylinder switching mechanism has the advantages of being simple and reasonable in structure, convenient to use and small in size.

Description

technical field [0001] The invention relates to the technical field of lock manufacturing, in particular to a lock cylinder switch mechanism with both manual and electric functions. Background technique [0002] With the continuous progress and development of science and technology, locks of various types, specifications and functions emerge in an endless stream. There are not only traditional mechanical locks including tumbler locks, but also electronic locks with better functional structure and high degree of automation. [0003] As for the traditional mechanical lock, it is formed by the mechanical combination of various parts, and the opening and closing of the lock is realized through the mechanical transmission between the various parts. The mechanical lock has a fully mechanical structure and does not require a power source. It can be adapted to various harsh places and is more convenient to use. Mechanical locks are also less expensive to manufacture. [0004] Howe...

Problems solved by technology

But despite this, such mechanical locks still have their drawbacks: the user accidentally loses the key, and even the owner of the house or items will cause a lot of trouble

[0008] The existing electronic lock has a complex structure and only has the function of electric unlocking. Once the electronic components in it are damaged, the lock will not be able to be opened, which will bring great trouble to the user.
