Definitions

  • the present invention relates to a lock, and more particularly to a burglarproof lock assembly.
  • a conventional lock assembly comprises a casing (6), a lock core (7) and multiple locking pin assemblies (8).
  • the casing (6) is mounted in a door panel or any object that needs to be locked and has a core hole (61) and multiple outer chambers (62).
  • the core hole (61) is circular and is formed longitudinally in the casing (6).
  • the outer chambers (62) are formed radially in the casing (6) and arranged side by side on the casing (6) and communicate with the core hole (61).
  • the lock core (7) is mounted rotatably in the core hole (61) and has a front end, an outer surface, a keyhole (71) and multiple inner chambers (72).
  • the keyhole (71) is formed axially in the front end of the lock core (7).
  • the inner chambers (72) are formed radially in the outer surface of the lock core (7), align respectively with the outer chambers (62) and communicate with the keyhole (71).
  • each locking pin assembly (8) is mounted respectively in the corresponding outer chambers (62) and inner chambers (72), and each locking pin assembly (8) has an outer block (81), an inner block (82) and an outer spring (83).
  • Each outer block (81) is mounted slidably in corresponding outer and inner chambers (62, 72), and each outer block (81) may have a recess (811), a through hole (812), an outer pin (813) and an inner spring (814).
  • the outer pin (813) is mounted slidably in the recess (811) and the through hole (812) of the outer block (81).
  • the inner spring (814) is mounted between the outer pin (813) and the outer block (81).
  • Each inner block (82) is mounted slidably in the inner chamber (72) and selectively extends into the keyhole (71).
  • Each inner block (82) may have a recess (821), a through hole (822) and an inner pin (823).
  • the inner pin (823) is mounted slidably in the recess (821) and the through hole (822) and abuts with the outer pin (813).
  • Each outer spring (83) is mounted in the outer chamber (62) and abuts against and provides a resilient force to the outer block (81) to push the outer block (81) into the inner chamber (72), such that the lock core (7) can not be rotated and is locked.
  • each locking pin assembly (8) may further have a block (84) mounted between the outer spring (83) and the outer block (81).
  • the present invention provides a burglarproof lock assembly to overcome the aforementioned problems.
  • An objective of the invention is to provide a burglarproof lock assembly.
  • a burglarproof lock assembly has a casing, a lock core, multiple locking pin assemblies, a supplementary locking assembly and a key.
  • the casing has a core hole and multiple outer chambers.
  • the core hole is formed longitudinally in the casing.
  • the outer chambers are formed radially in the casing and communicate with the core hole.
  • the lock core is mounted rotatably in the core hole of the casing and has a front end, an outer surface, multiple inner chambers and a keyhole.
  • the inner chambers are formed radially in the outer surface of the lock core and align respectively with the outer chambers.
  • the keyhole is formed axially in the front end of the lock core and communicates with the inner chambers.
  • Each locking pin assembly is mounted in one of the outer chambers and a corresponding one of the inner chambers and has an outer block, an inner block and an outer spring.
  • the outer block is mounted slidably in a corresponding outer chamber and a corresponding inner chamber.
  • the inner block is mounted slidably in the corresponding inner chamber and selectively extends into the keyhole.
  • the outer spring is mounted in the corresponding outer chamber and abuts with the outer block.
  • the supplementary locking assembly is mounted in one of the outer chambers and a corresponding inner chamber and has a first block, an outer spring and a second block.
  • the first block is mounted slidably in the corresponding outer chamber and the corresponding inner chamber and has an inner end and a locking recess formed in the inner end of the first block.
  • the outer spring is mounted in the corresponding outer chamber and abuts with the first block.
  • the second block is mounted slidably in the corresponding inner chamber, selectively extends into the keyhole and has a holding recess, a locking pin and a locking spring.
  • the holding recess is formed through the second block.
  • the locking pin is mounted slidably in the holding recess and selectively extends into the locking recess of the first block.
  • the locking spring is mounted in the holding recess and abuts with and provides a force to the locking pin to make the locking pin engage the locking recess.
  • the key has a contact surface, a cavity and a magnetic element. The cavity is formed in the contact surface of the key and corresponds to the locking pin when the key is inserted into the keyhole.
  • the magnetic element is mounted in the cavity.
  • a burglarproof lock assembly in accordance with the present invention comprises a casing (1), a lock core (2), multiple locking pin assemblies (3), a supplementary locking assembly (4) and a key (5).
  • the casing (1) has a core hole (11) and multiple outer chambers (12).
  • the core hole (11) is formed longitudinally in the casing (1).
