Description

The magnetic force auxiliary lock

Technical field

The utility model relates to a kind of lockset, relates in particular to a kind of in conjunction with unlocked by magnetic control and the magnetic force auxiliary lock of closing.

Background technology

Lockset used in everyday is generally common lockset and magnetic lock.Common lockset is generally and penetrates pass entirely, and built-in lock pearl group utilizes the outward appearance of key and shape and corresponding height to push the lock pearl to reach the purpose of unlatching.Yet, when the outward appearance correspondingly-shaped of key is identical, or without key, utilize light instrument directly will lock pearl when shifting the enable possition onto one by one, lock is promptly opened easily.Simple magnetic lock is and does not penetrate pass entirely, and built-in magnetic lock pearl utilizes on the key the magnetite and the magnetic lock pearl same sex to repel each other to reach the purpose of unlatching.Magnetic lock is easily found out the position of magnetic force point and magnetic pole, and combination correctly just can easily be opened.Therefore, lockset blocking function used in everyday is single, is easily found out and implements, and anti-theft feature is poor.

The utility model content

The purpose of this utility model is to provide a kind of and controls to realize the magnetic force auxiliary lock of multiple blocking function, good anti-theft effect in conjunction with magnetic force.

The purpose of this utility model is achieved by the following technical programs:

A kind of magnetic force auxiliary lock that the utility model provides, comprise lock core and key, described lock core comprises column type rotor, fixed body, the pearl of locking, locks pearl and spring down, described fixed body has the column type cavity, suitable and the pivot bush unit of the cavity of rotor and fixed body is provided with key hole therein vertically in the rotor; On the outer wall of rotor and fixed body respectively correspondence be provided with receiving hole and move and connect the hole, described receiving hole and moving connects that the hole connects mutually and is communicated with the key hole of rotor; The receiving hole and the moving of fixed body that lock pearl down, lock pearl and spring are placed on rotor connect in the hole; Described key has inserted link, and this inserted link is provided with and locks the pearl corresponding groove down; Receiving hole on the described rotor has one at least for placing the blind hole of magnetic lock pearl, and moving on this blind hole and the corresponding fixed body connects the hole connection, and blind hole is placed with magnetic lock pearl and spring with moving to connect in the hole, and this spring is arranged on the top of magnetic lock pearl; The position of the corresponding magnetic lock pearl of the inserted link of described key also is provided with magnetite.The moving of the receiving hole of the utility model rotor and fixed body connects the hole can many groups, and the following lock pearl length in each group can difference.Lock under blocking pearl and magnetic lock pearl is stuck in the joint of rotor and fixed body, and rotor can't rotate.The lock pearl has the different degree of depth under the groove correspondence on the key inserted link, insertion key inserted link rearward recess is pushed corresponding following lock pearl connects in the hole the moving of fixed body of pearl immigration of locking, this moment, the joint of upper and lower lock pearl overlapped with the joint of rotor and fixed body, magnetite on the while key inserted link is dismissed moving of fixed body because the same sex is repelled each other with the magnetic lock pearl of correspondence and is connect in the hole, reaches the purpose of opening lock thereby rotor is rotated.

The utility model can be done following further improvement: for ease of processing and assembling, described receiving hole, blind hole and moving connects the hole and is and radially is provided with and vertical with key hole, and each is organized receiving hole and move to connect hole and blind hole and move and connects the hole and arrange at grade vertically.The bottom outer wall indent of the described in addition pearl of lock down, the shape of rotor receiving hole is with the lock pearl is corresponding adaptive down, and the interior recess of lock pearl outer wall can be bearing in the corresponding position of rotor receiving hole so down, helps the location of lock pearl under blocking down.

Fixed body described in the utility model can be column type.This moment, rotor and fixed body can coaxial pivot bush units.The shape of cross section of described key inserted link can be rectangle.

The utlity model has following beneficial effect:

(1) have multiple blocking function, key must be at face shaping, lock correspondence aspect three of pearl length and the magnetic poles down, just can reach the purpose of unlatching.

(2) become three-in-one lockset in conjunction with auxiliary setting of magnetic force, key is transreplication not, good anti-theft effect,

(3) simple in structure, component are few, are easy to processing and assembling.
