" specific embodiment "
Below in conjunction with the accompanying drawings the specific embodiment of the present invention is described further：
In conjunction with shown in Fig. 1, Fig. 2 and Fig. 4, the unlocking head that the present embodiment provides includes：Key bar 10, outer shroud 20, central shaft
30th, steel ball 40, permanent magnet 50, support 60, steady pin 80, positioning ball 91, retaining spring 92, positioning plug 93 and electric magnet
(not showing in this part drawing).
In conjunction with Fig. 1 and Fig. 2, key bar 10 front end outer side is provided with the key bit 11 of convex hoop shape, key bit 11 periphery setting
There is key tooth 111 and drive projection 112, key tooth 111 is used for and is coordinated by the corresponding mechanism of the lock core of operation lock body, drives convex
Block 112 is used for the driving when key bit 11 rotates and is rotated together by the lock core of operation lock body.Referring to Fig. 4, open up in key bar 10
There is axially extending bore, this axially extending bore is stepped hole, including the narrower central shaft pilot hole in rear portion 12 and anterior wider permanent magnet
Pilot hole 13.Central shaft 30 can axially and movably be assemblied in central shaft pilot hole 12, and permanent magnet 50 fixing assembling is in permanent magnet
In pilot hole 13.
The front end of support 60 is fixedly installed reading terminal 65, and support 60 opens up the pilot hole 67 of before and after's insertion, and electric magnet is solid
Surely it is arranged at the rear end of the pilot hole 67 of support 60.Outer shroud 20 is sheathed on key bar 10 postmedian periphery, its front end and key bar
The convex hoop shape key bit 11 of 10 front end outer side settings is against the rear portion of outer shroud 20 and key bar 10 is assemblied in the pilot hole of support 60
In 67.Wherein, outer shroud 20 rear portion both sides longitudinally offer fixing groove 22, and two steady pins 80 are coordinated with fixing groove 22, by outer shroud
20 are fixed on support 60 so that outer shroud 20 will not opposite brackets 60 rotate.
In conjunction with shown in Fig. 2 and 4, key bar 10 offers steel ball pilot hole, outer shroud on the side wall of central shaft pilot hole 12
On 20 inwalls, the position of corresponding steel ball pilot hole axially offers draw-in groove 21, and steel ball 40 is assemblied at steel ball pilot hole, Ke Yiqian
Enter in draw-in groove 21 or disconnected.In the present embodiment, steel ball, steel ball pilot hole and draw-in groove are three groups, equiangularly spaced setting, if
The group number put is unrestricted in theory.
Central shaft 30 is made up of magnetic control material, and middle part is provided with buffer unit 31, when central shaft 30 by permanent magnet 50 attract to
When front movement is to setting position, buffer unit 31 is placed exactly in inside steel ball pilot hole so that steel ball 40 is cached in this buffer unit 31
And outer shroud 20 inwall between, now steel ball 40 rotates relative to outer shroud 20 without limitation on key bar；When central shaft 30 is made by electric magnet
During with being moved rearwardly into setting position, steel ball 40 is pushed outwardly by buffer unit 31 with the dislocation of steel ball pilot hole, central shaft 30 main body,
Steel ball 40 is partially submerged in the draw-in groove 21 of outer shroud 20 inwall, now steel ball 40 will limit key bar 10 20 turns of outer shroud relatively
Dynamic.
So that key bar 10 relative to outer shroud 20 and support 60 rotate when, can have an origin reference location, support 60, outer shroud
It is provided with detent mechanism between 20 and key bar 10.Specifically, support 60 longitudinally offers location hole 65 above pilot hole 67,
On outer shroud 20, correspondence position also offers location hole 25, and key bar 10 rear end correspondence position offers locating slot 15, positioning ball
91st, retaining spring 92 and positioning plug 93 are installed in positioning in the hole from the bottom to top, in key bar 10 outer shroud 20 and support 60 relatively
When turning to benchmark position, positioning ball 91 embeds in the locating slot 15 of key bar 10 rear end.
The unlocking head that above-described embodiment provides, its operation principle and process are as follows：
When not obtaining unblock mandate, electric magnet is in off-position, and permanent magnet 50 drives central shaft 30 to move forward, and makes
The buffer unit 31 obtaining central shaft 30 is located at steel ball pilot hole, and now steel ball 40 can be cached in buffer unit 31 and outer shroud 20 inwall
Between, key bar 10 can outer shroud 20 and support 60 dally it is impossible to realize the operation that unblocks relatively；When obtaining unblock mandate, electricity
Magnet is energized, and its adhesive end produces suction, overcomes the active force rear-guard of permanent magnet 50 to move central shaft 30 and is moved rearwardly into buffer unit
31 stagger steel ball pilot hole, and now steel ball 40 is partially submerged in the draw-in groove 21 of outer shroud 20 inwall, and key bar 10 can be with outer shroud 20
And support 60 rotates and rotates, operation can be unlocked to by operation lock body.
The only fully open and unrestricted present invention of above example, all creation purports based on the present invention, without creation
Property work equivalence techniques feature replace it should be considered as the application exposure scope.
