Please refer to Fig. 4, described block 3 comprises body 31 and connecting rod 32, one end of described connecting rod 32 is first through the through hole on junction plate 22, fix with one end of described body 31 again, the other end of described body 31 is fixed on described housing 1, and described body 31 can rotate relative to housing 1, described body 31 is provided with lug boss near a side of dead bolt 4, and described lug boss forms an arc-shaped side coordinating with dead bolt 4 with body 31.The other end of described connecting rod 32 is provided with anti-raising one's hat, and prevents that iron core 21 from coming off.Between described lug boss and described horizontal plane, have certain angle a, this angle a is 13 °, in other embodiments, this angle a between 10 ° to 15 ° all can, so when unblanking, be convenient to dead bolt 4 and depart from blocks 3.
Please refer to Fig. 2 and Fig. 5, described dead bolt 4 is provided with keyed end 42 that the fixed end 41 that matches with block 3 and hook match and for triggering the trigger end 43 of travel switch, described fixed end 41 is provided with for the fixing draw-in groove of torsion spring 6, described keyed end 42 is established by two locking bars and is formed, described two locking bars form a groove, described groove is for fixing described grab 5, and described trigger end 43 is relative with described keyed end 42, and described travel switch 7 is positioned at the below of described trigger end 43.
Please refer to Fig. 6, described grab 5 comprises fixed head 51 and connector 52, a closed ring structure of described connector 52 and described fixed head 51 fixing formation, and described fixed head 51 is provided with two fixing holes.Particularly, the both sides of described fixed head 51 are provided with all prolongs the fixed connecting plate that the direction perpendicular to fixed head extends to form, and described connector 52 is connected to form closed ring structure by two fixed connecting plates, by two fixing holes, grab can be fixed on door.In other embodiments, connector 52 takes the shape of the letter U (as shown in Figure 7), and connector 52 is by welding and the fixing loop configuration that forms a sealing of fixed head 51.
As shown in Figure 2, electronic lock is now locking state, and torsion spring 6 is given 4 one clockwise moments of dead bolt all the time, and now block 3 is subject to the counterclockwise moment loading of dead bolt 4, is rotated counterclockwise again, so reliable lock because described limited post 8 has limited described block 3.
When electromagnet 2 energisings, the iron core 21 of electromagnet 2 will be moved to the left rapidly predeterminated position, iron core 21 is fixing with connecting rod 52 by junction plate 22, therefore iron core 21 is moved to the left and can drives block 3 to turn clockwise, block 3 drives dead bolt 4 to be rotated counterclockwise to the dextrorotation change of team, when iron core 21 motion predeterminated position, now dead bolt 4 has departed from block 3, spring on iron core 21 is in compressive state, spring 21 can drive iron core 21 to move to initial position, simultaneously because torsion spring 6 is given 4 one clockwise moments of dead bolt all the time, when dead bolt 4 departs from after block 3, torsion spring 6 can drive dead bolt 4 to turn clockwise, the pulling force that dead bolt 4 revolves torsion spring 6 in repeating process can reduce gradually, when dead bolt 4 turns to certain angle, dead bolt 4 departs from grab 5, so opened electronic lock (as shown in Figure 3).
As shown in Figure 3, when grab 5 is to left movement, grab 5 can continue to promote dead bolt 4 and be rotated counterclockwise, after dead bolt 4 contacts with block 3, dead bolt 4 can promote block 3 and turn clockwise, the fixed end 41 of dead bolt 4 can be along the arc-shaped side rotation of block 3, in the process of block 3 rotations, can promote iron core 21 is moved to the left, spring on iron core 21 can be compressed simultaneously, after the fixed end 41 of dead bolt 4 has rotated along the arc-shaped side of block 3, spring on iron core 21 just promotes dead bolt 3 and rotates counterclockwise, until block 3 touches limited post 8, and then dead bolt 4 rotations always of whole process torsion spring 6, final dead bolt 4 is conflicted (as shown in Figure 2) mutually with block 3, be that electronic lock is locked.
The utility model electronic lock dead bolt 4 has the function of the STATEMENT OF FEDERALLY SPONSORED of grab connector, linkage lever and travel switch, has reduced number of spare parts its volume is reduced, and has also reduced cost simultaneously.Meanwhile, after electronic lock is locked, dead bolt 4 can also trigger travel switch 7, so that travel switch 7 continues the signal of telecommunication of having locked to security system server electronic lock.
These are only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure that utilizes the utility model manual and accompanying drawing content to do; directly or indirectly be used in other relevant technical fields, all in like manner within scope of patent protection of the present utility model.
