IU type three-dimensional code bolt self-locking padlock

Abstract

The invention discloses an IU type three-dimensional code bolt self-locking padlock, and relates to a lock. In order to overcome the disadvantages of small key amount of existing mechanical locks, small material strength of lock cylinders and weak lock tongue way, the IU type three-dimensional code bolt self-locking padlock abandons traditional pivoted lock cylinders; and in three dimensions of the space, lock codes are fully laid out, and a key code needle bar is directly used to push a lock code needle bar to achieve high key amount and high strength of the lock cylinders. According to a lock cylinder technology, a lock code screen and an embolus honeycomb are closely adjacent to each other, a plurality of holes are formed in the lock code screen in a two-dimensional mode, and a plurality of lock codes are installed in the holes to form a three-dimensional layout of the lock codes; a plurality of nests are arranged in the embolus honeycomb in a two-dimensional mode, and embolus and springs are installed in the nests; a screw shaft rod is connected to the lock screen, and a helical tooth pad and a compression spring are arranged between the shaft rod portion and the screw portionof the screw shaft rod; and a helical tooth face is disposed at the rear end of the embolus honeycomb, a lock pipe is connected to the front end of an I-shaped lock rod, an axial hole is formed in aninner cavity of the lock pipe, and a screw hole is formed in the front end of an U-shaped lock rod and is meshed with the screw portion for locking.

Description

technical field [0001] The invention relates to a lock, in particular to a padlock with a three-dimensional layout of a lock code and a key code and a lock core inserted into a screw hole in a bolt manner. Background technique [0002] At present, mechanical locks are mainly pin locks and blade locks with key slots. Because the processing of key slots is difficult, the material of the lock cylinder can only use low-strength brass. The existing pin lock cylinder uses an axial lock cylinder. This requires that there must be a key slot and a key handle rod, the pins are arranged in a linear arrangement, and the key teeth are also arranged in a linear manner. The concave and convex angle of the key teeth must be less than about 45 degrees to facilitate insertion into the lock cylinder, so that the longest pin and the shortest pin The differential length cannot be much larger than the diameter of the marbles, which greatly limits the number of marbles and the number of marbles, u...

Problems solved by technology

[0002] At present, mechanical locks are mainly pin locks and blade locks with key slots. Because the processing of key slots is difficult, the material of the lock cylinder can only use low-strength brass. The existing pin lock cylinder uses an axial lock cylinder. This requires that there must be a key slot and a key handle rod, the pins are arranged in a linear arrangement, and the key teeth are also arranged in a linear manner. The concave and convex angle of the key teeth must be less than about 45 degrees to facilitate insertion into the lock cylinder, so that the longest pin and the shortest pin The length of the difference cannot be much larger than the diameter of the pins, which greatly limits the number of pins and the number of pins, usually only single digits, and the key amount is only a few thousand

Generally, the bolt of the lock is directly inserted, so most of the burglars destructively unlock the lock by picking the bolt, which shows that the common way of inserting the bolt is very fragile.
