Abstract

The utility model relates to a magnetic concealed automatic locking device, which comprises a lock tongue and a groove seat of the lock tongue. Either the top end of the lock tongue or the bottom part of the groove seat of the lock tongue is provided with a strong permanent magnet. The other one is provided with ferromagnetic material or both of the top end of the lock tongue and the bottom part of the groove seat of the lock tongue are provided with strong permanent magnets. The utility model has the advantages that when a door which is provided with the magnetic concealed automatic locking device is opened, the lock tongue remains in a door body. Space is small and clother can not be scraped. When the door is closed, the lock tongue automatically springs in the groove seat of the lock tongue on a door frame to make the door locked. The door frame (mouth) is not ground in the process of closing the door. The utility model is suitable for various door locks (a spherical lock, a handle lock, etc.).

Description

The automatic lock uint of magnetic concealed type

The utility model belongs to the lockmaking industrial circle in the Furniture fittings industry.

The sealed parts in slotting pass of various in the past pin tumbler lockes (inserting pass formula door lock, as ball lock, hand holding lock) are that automatic lock uint all is to adopt the oblique dead bolt structure of spring.The door that this structure is installed is when opening, and it is external that dead bolt is exposed at door, and the pressure that relies on doorframe (mouth) that the dead bolt inclined-plane is produced at closing time is pressed into dead bolt in the dead bolt sleeve earlier, and (when door closure) dead bolt springs into doorframe and locks in the glossal canal seat hole then, makes door lock firmly.Because after this structure was installed, door dead bolt when opening was exposed at door external (an about 10-15mm), easily the scratch clothing is not attractive in appearance again, and when closing, and give prominence at outdoors dead bolt to wear and tear or to scratch doorframe (mouth), and its theftproof is also unreliable.

The purpose of this utility model is to be the automatic lock uint of concealed type for all slotting pass sealed door locks of formula provide the sealed parts in a kind of new type auto slotting pass.Door lock adopts this device to be installed on after door goes up, and when door was opened, dead bolt was in the door body, and door is when closing, and dead bolt inserts in the lock tongue slot seat on the doorframe automatically, and door lock is lived.

Structure of the present utility model comprises dead bolt and lock tongue slot seat two parts, its principle is the magnetic absorption principle, its architectural feature is: in the bottom of the top of dead bolt and lock tongue slot seat the two one of have the strong permanent magnetic body, another has ferrimagnet or the two all has the strong permanent magnetic body.Be following three kinds of implementations in more detail:

A, at lock tongue slot seat trench bottom the strong permanent magnetic body is installed, ferrimagnet is adopted on the dead bolt top.

B, on the dead bolt top strong permanent magnetic body is installed, ferromagnetic material is adopted in lock tongue slot seat bottom.

C, the strong permanent magnetic body is installed simultaneously, and is made the two adhesive mutually in lock tongue slot seat bottom and dead bolt top.

More than in three kinds of structures, should install between A structure dead bolt and its sleeve simple and easy anti-dead bolt throw away structure (with weak spring hold dead bolt or on dead bolt design card pearl structure all can), in case dead bolt is thrown out of when the normal switch door.In B and C-structure, be the ferrimagnet structure as the dead bolt sleeve, then needn't adopt and prevent among the A throwing away structure (magneticaction can make dead bolt not be thrown out of), be nonferromugnetic material as sleeve, then also should design the anti-structure that throws away.

The great advantage of the automatic lock uint of magnetic concealed type is that when door was opened, dead bolt rested in the body after door lock that this device is installed was satisfied with door and is gone up, and does not account for outdoors the space and does not draw clothing, and the process of closing the door does not scratch doorframe (mouth) again.After Men Zaiguan put in place, dead bolt sprang in the lock tongue slot seat notch on the doorframe automatically, makes pinning.Because lock tongued and grooved seat bottom magnetic adhesion is stronger, much larger than the power of spring structure, so its anti-group sled ability is more excellent, theftproof performance is stronger.This device can be widely used in various door locks.

Accompanying drawing is the generalized section of a kind of embodiment of the utility model: wherein among Fig. 11 for the dead bolt sleeve, 2 is lock tongue body, 3 is the strong permanent magnetic body, 4 is the dead bolt pull bar.1 is lock tongue slot seat main body among Fig. 2, and 2 is the dead bolt insertion portion on the groove seat, and 3 is the strong permanent magnetic body.

Claims

The automatic lock uint of magnetic concealed type is to insert the sealed parts in slotting pass that close in the class lock, comprise dead bolt and lock tongue slot seat two parts, it is characterized in that: in the bottom of the top of dead bolt and lock tongue slot seat the two one of have the strong permanent magnetic body, another has ferrimagnet or the two all has the strong permanent magnetic body.
