Description

A kind of theftproof lock that uses flexible key

Technical field

The utility model relates to a kind of theftproof lock, belongs to lock technology field.

Background technology

Security door is the room door that office, hotel, hotel, family etc. generally use, and main effect is to prevent that stealer from getting under the situation of key not having, to avoid finance stolen.Along with development of technology; The door lock of security door progressively develops into I-shaped lock, cross lock, flexure type lock by simple bullet letter lock; And magnetic lock, Fingerprint Lock etc. are multiple; The theftproof lock of present most of family is an I-shaped lock, and comparatively senior is cross lock and flexure type lock, and the room lock major part in hotel and hotel is a magnetic lock.Find that in use these locksets respectively have pluses and minuses.The I-shaped lock structure is comparatively simple, and price is low, but the anti-property opened is relatively poor, it is reported that the stealer that has is through opening I-shaped lock with tinfoil on the key pad in tens seconds; The structure of cross lock, flexure type lock is comparatively complicated, and it is higher to prevent opening rate, and the thief needs just might open more than half an hour, but price is higher; And magnetic lock is mainly used in hotel and hotel, and family security door is used less, but because its Magnetic Induction device is positioned at the lockset surface, is opened with other magnetic card by stealer easily.

The utility model content

The utility model technical problem to be solved provides comparatively simple, the anti-high theftproof lock that uses flexible key of rate of opening of a kind of structure.

The technical scheme that solves the problems of the technologies described above is:

A kind of theftproof lock that uses flexible key, it comprises lock body, lock core, dead bolt, lock body is installed on the body; Lock core is installed in the lock body, and lock core is connected with dead bolt, and its improvements are; It also has key to insert channel module and flexible key, and key inserts channel module and is installed in the lock body front portion, and key inserts has key to insert passage on the channel module; It is shaped as bent passage, and bottom and lock core that key inserts passage are relative, and the open-part of lock core is inserted channel end with key and is connected; Flexible key is made up of key head, flexible key bar, the shank of the key, and key head is connected with flexible key bar two ends with the shank of the key, and the interior hole shape that the peripheral shape of key head and key insert passage is complementary.

The above-mentioned theftproof lock that uses flexible key; Said lock core is a lock cylinder; The pellet shot from a slingshot of lock cylinder is along circumferential arrangement, arranged in a straight line or two-wire arrangement; The key bit contact surface that pellet shot from a slingshot is installed of lock core inserts the channel end central axis to vertical with key, and the key bit of key head is positioned on the key head or is distributed in the both sides of central axis.

The above-mentioned theftproof lock that uses flexible key, said lock core are Magnetic lockwork, and Magnetic lockwork comprises Magnetic Induction device and opening device, and the magnetic chip that is complementary with 1 above Magnetic Induction device is installed in key head.

The endoporus that the above-mentioned theftproof lock that uses flexible key, said key insert passage is shaped as the shape that circle, ellipse or other and key adapt, and key insertion passage bends at the middle part, and the angle of bending is 90 °-150 °.

The above-mentioned theftproof lock that uses flexible key, said flexible key also comprises wire-core in forming, and wire-core is through flexible key bar center, and key head is connected with the wire-core two ends with flexible key bar respectively with the shank of the key.

The usefulness of the utility model is:

It is the bending channel that is similar to 90 degree that the key of theftproof lock inserts passage, and general master key or other opener can't get into, and it is perpendicular that lock core marble and key insert passage; Can only open by the end face correspondence of key; This layout is generally dialled locking method and can't be opened, simultaneously since the Magnetic Induction device in lock body, except the magnetic chip of key end can contact the unlatching; Other magnetic card can't get into; And, can not arrive lock body inside externally because the magnetic force of magnetic card is limited, also just can not open.The utlity model has simple in structure, the anti-high advantage of rate of opening.
