The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Safety plug 13, two ends have the rectangle of blind screwhole, inner bolt hole peg button 11, outer screw uses as the emergent hole of opening the door, and in the middle of the side rectangle projection hammerlock 24 is arranged, in the corresponding side blind hole, spring 28, steel ball 27 are installed, the diagonal bar 20 of a projection is arranged on the perpendicular side.

Movable stand 17, for The shape front end has through hole, and respectively there is a slotted hole rear end, two side, and wherein the two ends of a slotted hole have an outside and inside flange respectively, be vertical sliding limit 22 outwards, be diagonal bar 18 inwardly, another slotted hole has only an outside vertical sliding limit 22, and perhaps all there is inside diagonal bar 18 on movable stand 17 both sides.

Holder 19 for there is the frame shape of rectangular through-hole the centre, has boss on the leading flank outer wall, and two arc flutings 26 that cooperate with steel ball 27 are arranged on the inwall, in the middle of the corresponding trailing flank rectangular aperture is arranged, and two protruding joint pins 21 of symmetry are respectively arranged on the both ends of the surface.

Outer shift fork 23, interior fork 29 are connected and are linked to be an integral body on the square shaft, and the one side is fan-shaped, and a side is cylindrical for the band square through hole.Outer shift fork 23 also has a rectangular through-hole at fan-shaped middle edge.

Square shaft is threaded whole by the outer square shaft 4 of band blind screwhole with interior square shaft 9 usefulness of band screw rod.

Also be fixed with spring 8, collar 7 at inside and outside cover plate 12,5 and inside and outside spanner 10,3 junctions.

Be with an end of the tongue bar 14 of spring 15, the through hole that passes on the movable stand 17 is fixed on the dead bolt 1, the centre is equipped with the holder 19 of safety plug 13, put on movable stand 17 centre positions, and spring 16 two ends are socketed in respectively on the boss of tongue bar 14 and holder 19, movable stand 17 is inserted in the housing 25, making two on it slide limit 22 can be on housing 25, slide in the low groove, square shaft pass housing 25 and in, outer cover plate 12, square hole on 5, in,

outer shift fork

29,23 be socketed in respectively in, outer square shaft 9, on 4, with screw that two housings 25 are fixing again, joint pin 21 difference rivet clasps are at housing 25, square shaft is more respectively with interior, outer spanner 10,3 connect into integral body, in, outer cover plate 12, the butt joint of 5 usefulness screws is integral.

Rotating spanner is with Men Lakai, in door, outwards press the button 11 on the safety plug, second groove 26 that steel ball 27 on it moves on the holder 19 is interior fixing, hammerlock on it 24 is detained in the breach that is embedded on the outer shift fork 23 simultaneously, if rotate outer spanner 3, outer shift fork 23 can or not opened by rotary door, at this moment as long as rotate interior spanner 10, stretch in the breach on the movable stand 17 by interior shift fork 29 two ends, stirring movable stand 17 moves it backward, diagonal bar 18 on movable stand moves, collide the diagonal bar 20 on the safety plug, safety plug 13 is moved inward, and steel ball 27 is got back to again in first groove 26, hammerlock on it 24 break away from outer fork 23 on the contacting of breach, at this moment dead bolt 1 under the effect of spring 16 with regard in the indentation housing 25, the door just open, at this moment in, outer spanner 10,3 is all free to rotate, under the effect of spring 16 dead bolt stretched out outdoors and shut the door.Also be provided with emergent hole 2 on the outer cover plate 5,, then rotate 3 of outer spanners and just can open if child is locked in the inside or have burst accident, an end of the inside top of available screwdriver safety plug 13 to make it break away from outer shift fork 23, safe in utilization, reliable.
