Definitions

  • the present invention relates to a hardware lockset, in particular to an anti-theft lockset for a pin tumbler lock.
  • locksets There are various kinds of locksets which are diverse in structure, of course, among which there are locksets having excellent anti-theft performance.
  • locksets most of locksets, as they have less anti-theft orientations due to their simple structure, may be unlocked in a very short time. This is so-called technical unlocking. Burglaries thus happen, and people's property and security are threatened.
  • criminals can always buy some tools against the anti-theft performance, and thus can easily technically unlock some anti-theft facilities such as anti-theft doors, anti-theft locks, etc.
  • a state of the art lockset is known from document CN 103437600 A .
  • An objective of the present invention is to provide a lockset having excellent anti-theft performance, to solve the problems in the prior art.
  • an anti-theft lockset including a key, a lock cylinder and a lock shell, a first pin tumbler hole and a second pin tumbler hole being provided in the front part of the lock shell, a third pin tumbler hole and a fourth pin tumbler hole corresponding to the first pin tumbler hole and the second pin tumbler hole on the lock shell being provided in the front part of the lock cylinder, a fifth pin tumbler hole being provided in the rear part of the lock shell, a sixth pin tumbler hole corresponding to the fifth pin tumbler hole being provided in the rear part of the lock cylinder, a corresponding pin tumbler being provided in each of the pin tumbler holes, the key being matched with the lock cylinder, characterized in that the key includes a key handle, a connecting portion and a key head, the key head being mounted on the connecting portion, the connecting portion being connected to the key handle; columns are provided around a hole, into which the key head is to be mounted, on the connecting portion; a
  • the pin tumbler in the sixth pin tumbler hole is thus resisted against the outer circumferential walls of the flanges, such that when the key is inserted into the lock cylinder and pushed inward to the proper position, the slide bar will be inserted into the long hole on the key head and moved, so that the pin tumbler in the sixth pin tumbler hole falls onto the corresponding flanges, whereby the pin tumblers in the sixth pin tumbler hole on the lock cylinder are exactly flushed with the outer circumferential surface of the lock cylinder.
  • the connecting portion and the key handle form an integrated structure. A slope is provided between the flanges different in the outer diameter. The columns around the hole on the connecting portion are different in height.
  • the present invention not only the biting on the key head is matched with the pin tumblers in the pin tumbler holes, but also the conical chute on the slider is matched with the pin tumblers in the pin tumbler holes, and even the step-like flanges on the slide bar are matched with the pin tumblers in the pin tumbler holes. That is, there are three anti-theft functions.
  • the step-like flanges on the slide bar are pushed immediately.
  • the pin tumblers and the matched flanges among those flanges are completely misaligned, and it is thus less able to accomplish unlocking. In this way, the possibility of technical unlocking is eliminated.
  • the present invention has a scientific and reasonable structure and excellent anti-theft performance.
  • such an anti-theft lockset includes a key, lock cylinder 12 and a lock shell 20, first pin tumbler hole 18 and a second pin tumbler hole 19 being provided in the front part of the lock shell 20, a third pin tumbler hole 11 and a fourth pin tumbler hole 10 corresponding to the first pin tumbler hole 18 and the second pin tumbler hole 19 on the lock shell 20 being provided in the front part of the lock cylinder 12, a fifth pin tumbler hole 21 being provided in the rear part of the lock shell 20, and a sixth pin tumbler hole 13 corresponding to the fifth pin tumbler hole 21 being provided in the rear part of the lock cylinder 12.
  • the "front part of the lock shell 20" herein refers to an end close to a key insertion hole, and an end far away from the key insertion hole is the rear part of the lock shell 20.
  • Corresponding pin tumblers 26, 25, 22, 23, 27, and 24 are arranged in the first pin tumbler hole 18, the second pin tumbler hole 19, the third pin tumbler hole 11, the fourth pin tumbler hole 10, the fifth pin tumbler hole 21 and the sixth pin tumbler hole 13, and a small spring is arranged in each of the pin tumbler holes within the lock shell 20.
  • the key is matched with the lock cylinder 20.
  • the pin tumblers assembled in the lock cylinder are all conical, and the lock shell 20 is mounted within a lock sleeve 6. Those are well known and will not be repeated herein.
  • the key includes a key handle 1, a connecting portion 2 and a key head 4, the key head 4 being mounted on the connecting portion 2, the connecting portion 2 and the key handle 1 being connected to form an integrated structure.
  • Five columns 3 different in height are uniformly distributed around a hole, into which the key head 4 is to be mounted, on the connecting portion 2.
  • a long hole 28 is formed on the key head 4.
  • Five sliders 7 corresponding to the columns 3 are arranged in the lock cylinder 12. As the height of the columns 3 may be designed arbitrarily, the length of the slider 7 corresponding thereto is different. Locksets manufactured in this way have various variations, and this avoids opening various locks with a same key. It is thus clear that, as there are many variations of height of the columns 3, the possibility of opening various locks with a same key is extremely low.
  • a conical chute 8 fitted with the pin tumbler 23 in the fourth pin tumbler hole 10 is arranged on the slider 7.
  • the pin tumbler 22 in the third pin tumbler hole 11 is fitted with the biting 5 on the key head 4.
  • the slide bar 14 is arranged in the lock cylinder 12, with a plurality of flanges 15 different in the outer diameter being provided on the slide bar 14, and the outer diameter of the flanges 15 is gradually increased.
  • the pin tumbler 24 in the sixth pin tumbler hole 13 is resisted against the outer circumferential wall of each of the flanges, and a slope 29 is arranged between adjacent flanges for transition, so that the pin tumbler 24 can easily move among the flanges 15.
  • the slide bar 14 can be inserted into the long hole 28 of the key head 4.
  • Springs 9 and 17 are arranged at ends of both the slider 7 and the slide bar 14, respectively.
  • a deep hole 16 into which the spring 17 at an end of the slide bar 14 is partially placed, is formed on the slide bar 14. In this way, the stable elasticity of the spring 17 is maintained.
  • the second embodiment of the present invention is to replace the conical chute 8 on the slider 7 with a bulge 30 structure, referring to Fig. 7 to Fig. 9 .
  • the remaining structures are all the same.
  • the key is inserted into the lock cylinder 12, and the biting 5 on the key head 4 is matched with the pin tumbler 22 in the third pin tumbler hole 11 on the lock cylinder 12.
  • the columns 3 on the connecting portion 2 push the corresponding slider 7 in the lock cylinder 12, and after the slider 7 moves, the pin tumbler 23 in the fourth pin tumbler hole 10 on the lock cylinder 12 exactly slides into the conical chute 8 of the slider 7, or exactly moves to the top of the bulge 29 of the slider 7.
  • the slide bar 14 will be inserted into the long hole 28 on the key head 4.
  • the slide bar 14 When the key is pushed to the proper position, the slide bar 14 will move, so that the pin tumbler 24 in the sixth pin tumbler hole 13 falls onto the corresponding flanges 15 different in the outer diameter.
  • the pin tumblers in the third pin tumbler hole 11, the fourth pin tumbler hole 10 and the sixth pin tumbler hole 13 on the lock cylinder 12 are exactly flushed with the outer circumferential surface of the lock cylinder 12; meanwhile, the pin tumblers in the first pin tumbler hole 18, the second pin tumbler hole 19 and the fifth pin tumbler 21 in the lock shell 20 are exactly flushed with the inner circumferential surface of the lock shell 20.
  • the lock cylinder 12 may be rotated and unlocking is realized.
  • the key head 4 When the key is pulled out, the key head 4 is pulled out too.
  • the pin tumbler 22 in the third pin tumbler hole 11 moves upward along with the biting 5 on the key head 4, so that the pin tumbler 22 in the third pin tumbler hole 11 partially comes into the first pin tumbler hole 18.
  • the spring 9 at an end of the slider 7 drives the slider 7 to move, so that the pin tumbler 23 in the fourth pin tumbler hole 10 moves out from the conical chute 8 or the pin tumbler 23 in the fourth pin tumbler hole 10 moves down from the top of the bulge 29.
  • the pin tumbler 23 also partially comes into the second pin tumbler hole 19, and after the pin tumbler 23 slides down from the top of the bulge 29, the pin tumbler 25 in the second pin tumbler hole 19 partially comes into the fourth pin tumbler hole 10.
  • the slide bar 14 is pushed by the spring 17 at an end of the slide bar 14, so that the position of each of the flanges 15 changes.
  • the pin tumbler 24 in the sixth pin tumbler hole 13 moves among the flanges 15, so that the pin tumbler 24 in the sixth pin tumbler hole 13 partially comes into the fifth pin tumbler hole 21 within the lock shell 20, or the pin tumbler 27 in the fifth pin tumbler hole 21 partially comes into the sixth pin tumbler hole 13.
  • the slide bar 14 in the lock cylinder 12 when in locked state, the slide bar 14 in the lock cylinder 12 may be moved by an external object.
  • the slide bar 14 moves immediately when the external object comes into contact with the slide bar 14.
  • the flanges 15 different in the outer diameter move correspondingly.
  • the position of the pin tumbler 24 in the sixth pin tumbler hole 14 changes correspondingly. Only when the slide bar 14 moves to the accurate position, the pin tumblers 24 in the sixth pin tumbler hole 13 will be flushed with the outer circumferential surface of the lock cylinder 12.
