Lining of the present utility model 5 and for example shown in Figure 3, an end of lining 5 exposes lock body 35, and fixedlys connected with the outer knob 1 outside the lock body 35; The back-up ring of the other end of lining 5 and shifting block 38 inboards corresponding (the back-up ring center is described circular hole), and be provided with clamping part I 39 in its bottom centre; Described clamping part I 39 is a cylinder, and has a rectangular slot bottom it, makes it to be the jaw shape; This clamping part I 39 can just be passed the circular hole of shifting block 38 central upper portion, and enters into the inboard of clamping part II 37, and the rectangular slot of bottom is done the gap clamping with the plectrum 36 of catch bar 23 all the time; Described first through hole 17 is positioned at the center of above-mentioned cylinder bottom rectangular slot.

And for example shown in Fig. 4-1, Fig. 4-2, Fig. 4-3, described STATEMENT OF FEDERALLY SPONSORED 34 is a cylindrical tube, and the radius of this cylindrical tube is identical with the internal diameter of electromagnetic coil II 32; The end of cylindrical tube is provided with clamping part II 37, and the rear portion of cylindrical tube is a clamping part III 44.Described clamping part II 37 is an inner cylinder that communicates with cylindrical tube, the back-up ring of this cylinder outer rim and shifting block 38 inboards is corresponding, the side that cylinder does not link to each other with cylindrical tube is provided with two symmetrical pin sheets, and this pin sheet is corresponding with two grooves that shifting block 38 central upper portion circular hole outer rim symmetries are turned up the soil.Middle part in the cylinder, form described circuit 21 by cylinder internal diameter and cylindrical tube internal diameter, on the circuit 21, be provided with the described first draw-in groove 22(perpendicular to two pin sheet line places and see Fig. 4-2).Described clamping part III 44 is the pin sheet II (seeing Fig. 4-3) of two positions symmetry, and wherein a pin sheet II and first draw-in groove 22 are located along the same line; Cylindrical tube is identical with the length of pipe in the electromagnetic coil II 32 together with the length of pin sheet II.

And for example shown in Fig. 6-1, Fig. 6-2, catch bar 23 has cylinder (this cylinder radius is corresponding with above-mentioned cylindrical tube internal diameter) with described clamping part I 39 corresponding plectrums 36 for the top, taking off post of this plectrum 36 and described driving section 13 is 18 corresponding, and does the gap clamping with the rectangular slot of clamping part I 39 bottoms all the time.And its side is provided with pin II 20; Described pin II 20 is corresponding with first draw-in groove 22 on the described circuit 21.Also can be provided with a fixture block 19 in pin II 20 relative plectrum 36 1 sides, described fixture block 19 is corresponding with the circuit 21 at middle part in the clamping part II 37.

For another example shown in Fig. 5-1, Fig. 5-2, Fig. 5-3, described rotating shaft piece 31 1 sides are and the corresponding pin 25 of STATEMENT OF FEDERALLY SPONSORED 34 interior pipes, these pin 25 both sides are provided with the clamping part III 44 corresponding second draw-in groove 45(sees Fig. 5-2), the 3rd blind hole 27 at pin 25 centers be built-in with second spring 26 and with described catch bar 23 contacted release links 24; The opposite side of rotating shaft piece 31 is a turning cylinder 29, and this turning cylinder 29 is provided with inner button 30, and rotating shaft piece 31 middle parts have a snap ring 28.The length of described catch bar 23 and pin 25 can be when pin II 20 falls into first draw-in groove 22, can make catch bar 23 and STATEMENT OF FEDERALLY SPONSORED 34 mutual clampings, thereby reaches the purpose of radio-frequency card and electronic key unlocking.

The power supply of described electromagnetic coil I 6 and electromagnetic coil II 32 adopts external power supply.

It below is the utility model concrete course of action in use.

When using electronic key unlocking: have the electron key of authority to make 6 energisings of electromagnetic coil I, two magnetic posts 7 became attracting state from originally repelling each other, and entered into fully in first blind hole 8 hole of movable magnetic post 7 from lining 5 outer walls; At this moment, lock core portion 4 can rotate in lining 5, and lock core portion 4 promotes driving section 13 left simultaneously; Because first spring, 14 intensity in the driving section 13 are higher than second spring 26 in the rotating shaft piece 31, therefore, catch bar 23 is promoted left; And the plectrum 36 of the clamping part I 39 clamping catch bars 23 of lining 5 front ends together rotates with lining 5, so that the pin II 20 of catch bar 23 falls in first draw-in groove 22 of STATEMENT OF FEDERALLY SPONSORED 34, makes catch bar 23 and STATEMENT OF FEDERALLY SPONSORED 34 relative fixed; And pass plectrum 36 on the clamping part I 39 clamping catch bars 23 of shifting block 38, STATEMENT OF FEDERALLY SPONSORED 34 and lining 5 can be rotated synchronously, again because of the clamping part II 37 of STATEMENT OF FEDERALLY SPONSORED 34 with shifting block 38 clampings, make it interlock, rotate simultaneously so can drive shifting block 38.

When using radio-frequency card to unblank: after swiping the card, 32 energisings of electromagnetic coil II promote catch bar 23 left; And because lining 5 is fixedly connected with outer knob 1, therefore, by rotating outer knob 1 plectrum 36 of catch bar 23 is fallen in first draw-in groove 22, again because of the clamping part II 37 of STATEMENT OF FEDERALLY SPONSORED 34 with shifting block 38 clampings, outer knob 1 can drive shifting blocks 38 by STATEMENT OF FEDERALLY SPONSORED 34 and rotate and unblank.

Be with being appreciated that, more than about specific descriptions of the present utility model, only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
