Two-piece chain soft key lockset

Abstract

The invention relates to the technical field of anti-theft locksets, in particular to a two-piece chain soft key lockset, which comprises a lock and a chain link soft key matched with the lock. The two-piece chain soft key lockset is characterized in that the chain link soft key is a two-piece chain link soft key, an outer plug, a middle plug and an inner plug are sequentially arranged in the lock from outside to inside, the outer side of the outer plug is slidably connected with the lock through a steel ball in a circular steel ball rail, the inner side of the outer plug is abutted to a key positioning groove on the outer side of the middle plug through a steel ball and a spring in a spring hole, a key channel in the outer plug is communicated with a key inlet in the middle plug, a shifting fork on the inner side of the middle plug penetrates through an arc shifting fork moving rail on the inner plug and is placed between the middle plug and the inner plug to realize locking through a locking column on the outer side of the shifting fork, the two-piece chain link soft key is bilaterally separated by the key inlet in the middle plug and passes through an arc lock channel to enter a radial lock channel when inserted into the key channel, a spring in a spring lock channel in the middle plug is correspondingly pressed down by the two-piece chain link soft key, the locking column is completely pressed into the inner plug, and the middle plug and the inner plug rotate under the action of the two-piece chain link soft key and drive the shifting fork to rotate in the arc shifting fork moving rail. Owing to the structure, the two-piece chain soft key lockset has the advantages of novel structure, low interchangeability, capability of preventing technical opening, forced opening, drilling and blocking, and the like.

Description

technical field [0001] The invention relates to the technical field of anti-theft locks, in particular to a two-body chain soft key lock. Background technique [0002] As we all know, the existing locks on the market are usually hard key locks. The lock cylinders in the hard key locks are all straight-type lockways. There are pinholes on one side of the lockway. The pinholes have double rows of pinholes. There are also four rows of pin pin lock holes and cylindrical pin pin lock holes. When the key is inserted, the teeth of the key will touch the pin pins on one side of the lockway to the open position, and then turn the lock cylinder to achieve the purpose of unlocking. This structure The disadvantage is that the thief can easily use special tools such as lock guns, steel sheets, steel wires or screws to move the pins in the lock cylinder to achieve technical opening, or use some hard tools to insert into the lockway, pry and destroy the lockway. The pin on the side makes...

Problems solved by technology

[0005] To sum up, the disadvantages of the three locks mentioned above are: the keyholes are all straight type, and this type of straight type key is easy to be damaged by glue or foreign matter, if it is light, you need to find a professional to repair it, and if it is serious, the lock will be scrapped
