Description

The key bit magnetic structure that unblocks

Technical field

The present invention relates to the key bit structure of Intelligent key, a kind of specifically key bit magnetic structure that unblocks.

Background technology

Present microcomputer anti-error system, the general Intelligent key with code identification function that uses carries out release and locking to mechanical lock, accomplishes anti-misoperation with this.

At present, employed Intelligent key on the market, its key bit are double-decker; In release and locking process, need cooperatively interact through the magnetic post in the Intelligent key and the steel ball in the lockset or magnetic steel ball, could complete operation; Therefore must assembly steel ball or magnetic steel ball in the lockset, the Intelligent key of this kind structure causes the structure more complicated of lockset; And after the steel ball generation corrosion or loss of excitation in the lockset, will influence the operate as normal of lockset.

Summary of the invention

To the deficiency and the defective of above prior art, the object of the present invention is to provide a kind of key bit magnetic structure that unblocks.

The objective of the invention is through adopting following technical scheme to realize:

A kind of key bit magnetic structure that unblocks comprises: axle, magnetic lock pin, alignment pin in key headgear, positioning sleeve, the key bit;

Axle is provided with lockpin hole in said key headgear, positioning sleeve and the key bit; What this magnetic lock pin was movable is arranged in this lockpin hole; The degree of depth of the lockpin hole that this key bit puts is greater than the length of this magnetic lock pin, and the degree of depth sum of the lockpin hole in this positioning sleeve and this key bit on the axle is less than the length of this magnetic lock pin;

Axle is provided with dowel hole in said key headgear and the key bit, in the dowel hole that this alignment pin is arranged in this key headgear and the key bit spool, passes the position of positioning sleeve at this alignment pin, and this positioning sleeve is provided with avoiding hollow groove.

As optimal technical scheme of the present invention, said key headgear and positioning sleeve are provided with the position probing hole.

As optimal technical scheme of the present invention, the end of axle is provided with limited impression in the said key bit.

Compared with prior art, the key bit among the present invention adopts axle three layer construction in key headgear, positioning sleeve, the key bit, relies on the magnetic lock pin that key bit is locked and release; To reach the purpose of the tool that unblocks, therefore, need not to be provided with the steel ball structure of magnetic motion in the lockset; Simplified lockset; Strengthened the adaptive capacity to environment of lockset, can not occur because of environmental problem causes loss of excitation, corrosion, and the phenomenon that causes lockset to damage.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the present invention is described further:

Fig. 1 is the unblock overall schematic of structure of key bit magnetic of the present invention.

Fig. 2 is the unblock exploded perspective view of structure of key bit magnetic of the present invention.

Fig. 3 is the unblock decomposition view one of structure of key bit magnetic of the present invention.

Fig. 4 is the unblock decomposition view two of structure of key bit magnetic of the present invention.

The specific embodiment

See also Fig. 1, be the unblock overall schematic of structure of key bit magnetic of the present invention.This key bit magnetic structure that unblocks comprises axle 103 three layer constructions in the key headgear 101, positioning sleeve 102, key bit; Be arranged on the outer field key headgear 101 that is; The intermediate layer is a positioning sleeve 102, and internal layer is an axle 103 in the key bit, and the end of axle 103 is provided with limited impression 104 in this key bit.

See also Fig. 2, Fig. 3 and Fig. 4; All be provided with lockpin hole 105 respectively on the axle 103 in this key headgear 101, positioning sleeve 102 and the key bit; 106 movable being arranged in this lockpin hole 105 of magnetic lock pin; The degree of depth of the lockpin hole 105 on this key headgear 101 is greater than the length of this magnetic lock pin 106, and the degree of depth sum of the lockpin hole 105 in this positioning sleeve 102 and this key bit on the axle 103 is less than the length of this magnetic lock pin 106.

Said key headgear 101 is provided with dowel hole 107 with the interior axle 103 of key bit; Alignment pin 108 is arranged in the dowel hole 107 on this key headgear 101 and the interior axle 103 of key bit; Pass the position of positioning sleeve 102 at this alignment pin 108, this positioning sleeve 102 is provided with avoiding hollow groove 109.

On this key headgear 101 and positioning sleeve 102, also be provided with position probing hole 110, when key bit carries out locking or release action, be convenient to Intelligent key the running position of key bit is detected.

During locking; Magnetic post in the Intelligent key (figure does not show) is in same magnetic pole with the magnetic lock pins of being located in the lockpin hole 105 106, and magnetic lock pin 106 produces mutual repulsive force with the magnetic post, and magnetic lock pin 106 is pushed in the lockpin hole 105 of axle 103 in the key bit of key bit internal layer; Because the length of magnetic lock pin 106 is greater than the degree of depth sum of the lockpin hole 105 on the axle 103 in positioning sleeve 102 and the key bit; Therefore, axle 103 threes are fixed together by magnetic lock pin 106 in key headgear 101, positioning sleeve 102, the key bit, when Intelligent key inserts lockset; Positioning sleeve 102 is fixed in the lockhole of lockset and can not rotates; And key headgear 101 can not rotate with the interior axle 103 of key bit, therefore, can't carry out unlocking action.

When unblanking,, make the magnetic lock pin of being located in the lockpin hole 105 106 be in different magnetic pole with the magnetic post through the magnetic pole of conversion Intelligent key inside magnet column; Magnetic lock pin 106 produces mutual attraction with the magnetic post, and magnetic lock pin 106 is drawn in the lockpin hole 105 in the key headgear 101, because the degree of depth of the lockpin hole 105 on the key headgear 101 is greater than the length of magnetic lock pin 106; Therefore; After Intelligent key inserted lockset, axle 103 threes were not fixed together by magnetic lock pin 106 in key headgear 101, positioning sleeve 102, the key bit, when rotating Intelligent key; Positioning sleeve 102 is fixed in the lockhole of lockset and can not rotates; And key headgear 101 is provided with alignment pin 108 with the interior axle 103 of key bit, and key headgear 101 passes through 103 rotation in the alignment pin 108 drive key bits, and the pin of unblanking (figure does not show) of interior 103 terminal limited impressions 104 of key bit and lockset is bitten and closed; And drive the pin rotation of unblanking, lockset is opened.After lockset was unblanked, axle 103 terminal limited impressions 104 were blocked by the lateral pin of lockset (figure does not show) in the key bit, could take out Intelligent key after needing lockset to reset, to prevent away do-nothing operation.

The above is merely preferred embodiment of the present invention, is not to be used for limiting practical range of the present invention; Every according to equivalence variation and modification that the present invention did, all covered by the scope of claims of the present invention.
