Definitions

  • This invention involves a kind of improved structure of a key cylinder
  • this invention provides an improved structure of a key cylinder. It is designed to be compact, and can positively limit the rotating opening of the unlocking cam under certain damage by force, which improves its burglar resistance and has a high reliability.
  • a key cylinder including:
  • this invention includes a left cylinder body 1 and right cylinder body 2, connected by connection member 3.
  • a left barrel of key cylinder 1 and a right barrel 5 of key cylinder 2 are inserted into a left cylinder body or housing 1 and the right cylinder body or housing 2 respectively. Between the left cylinder body 1 and the right cylinder body 2, an unlocking cam 6 is set. An extension from the side of the connection member 3 forms a fixed block 7.
  • the fixed block can be set between the left barrel of key cylinder 1 and the unlocking cam 6, or between the right barrel 5 of key cylinder 2 and the unlocking cam 6, depending on the specific requirement.
  • the indication here of right or left, is not to prescribe a limit to the range.
  • the left cylinder barrel 4 and the unlocking cam 6 are connected and driven by the left driving shaft 8 which extends through a bore in the fixed block 7.
  • the unlocking cam 6 and the right barrel 5 of key cylinder 2 are connected and driven by the right driving shaft 9.
  • the connection member 3 is initially positioned in the left key cylinder 1 by a circlip 26 which engages in a slot 27 on the left key cylinder 1 and secured with bolt 25 which extends through bore 24 before engaging with a threaded bore in the left key cylinder 1.
  • the connection member 3 is secured to the right key cylinder 2 in a similar manner.
  • a sliding stop pin 13 is set at an eccentric position from the axis of rotation of the unlocking cam 6 sets. Referring also to figure 2 , one end of sliding stop pin 13 abuts a lifting pin 11, the other end cooperates with the restraining plug 12.
  • two circumferential grooves 14 are symmetrically formed.
  • Two lock-stopping channels 15 are formed in a radial direction in the unlocking cam 6, the lock-stopping channels 15 each being equipped with a lock-stopping spring 16 and a lock shotpin 17, packed by the sealing covers 21, and the lock shotpin 17 is corresponds with the circular grooves 14.
  • the effect of the cooperation between the lock shotpin 17 and the circular grooves 14 is to prevent burglars from removing the sliding stop pin 13 in order to rotate the unlocking cam 6.
  • the lock shotpin 17 maintains an engagement with the sliding stop pin 13 through the circumferential groove 14.
  • Limit lugs 18 are set on the two sides of walls of the fixed block 7, which prevents the whole key cylinder being knocked into the lock body by force while the key cylinder as a whole is installed in the lock body.
