Description

A kind of electromagnetism fore shaft of door lock

The utility model relates to a kind of lock of handling or controlling with magnetic force.

Existing utility model patent ZL97235360.7, name is called: a kind of door lock remote control, this patent is made up of base 9, fore shaft 1 and locking device thereof and the detent mechanism of a glossal canal 6 with lock.Fig. 1 is the schematic diagram that the fore shaft of the door lock of this utility model patent is in unlatching and closure state.Dead bolt 5 can be stuck in and pin in the lock tongue slot 6 or be released as arrow 8 directions.Fore shaft 1 is the center with pivot 2, conversion between home position 3 and off-position 4.Its duty has three kinds: the one, and dead bolt 5 pulls out in lock tongue slot 6, and dead bolt 5 is released, and door is in opening; The 2nd, dead bolt 5 is positioned at lock tongue slot 6, but dead bolt 5 is not locked, and door is in closure but the state that can also be opened; The 3rd, dead bolt 5 is positioned at lock tongue slot 6, and fore shaft 1 is locked the state (first kind of state is shown in Fig. 5 solid line, and second and third kind state is shown in Fig. 5 double dot dash line) that door is in closure and can not be opened.Described locking device is made of fore shaft 1, electromagnetic coil 1O and steel pin (21,22,23).Establish upper and lower articulated jib (24,28) on the described fore shaft 1, last articulated jib 24 stretches out a boss 13 to the outer, and this boss 13 is provided with pin-and-hole 29.Establish the upper and lower flange (12,14) of (39,40) of band through hole (37,38) and axis hole in the groove 11 of base 9.Lower flange 14 is the Z type, and through hole 38 is positioned at its upper end, and axis hole 40 is positioned at its lower end.Last articulated jib boss 13 places between the upper and lower flange (12,14), and pin-and-hole 29 and through hole (37,38) concentric.Pivot 2 cooperates with the upper and lower articulated jib (24,28) of fore shaft and axis hole (40, the 39) activity of upper and lower flange (12,14), and described upper flange 12 is thicker than end on the lower flange 14, and end is identical with last articulated jib boss 13 thickness on the lower flange 14.Steel pin 21 length are identical with upper flange 12 thickness, and the length of steel pin (22,23) is identical with lower flange 14 thickness.Steel pin 23 lower ends are provided with a microswitch 15, and electromagnetic coil 10 places in the groove 11, its iron core 25 positions and steel pin (21,22,23) concentric and adjacent.Fore shaft 1 device is inserted with in the doorframe of mortise.Owing to be enclosed within the effect that also is provided with torsion spring 27 on the pivot 2, therefore, fore shaft 1 can restore and discharge conversion between two kinds of positions.The excircle of following articulated jib 28 is provided with the plane 33 of a projection, at fore shaft 1 home position, this plane 33 is vertical with plane 32, Z-shaped lower flange stage casing, when fore shaft 1 turns to plane 33 when offseting with plane, Z-shaped lower flange 14 stage casing 32 (shown in double dot dash line among Fig. 5) around pivot 2, fore shaft 1 goes to extreme position.According to the principle of aforementioned three kinds of states, the position of arrangement steel pin (21,22,23) in through hole 37, pin-and-hole 29 and through hole 38 can make door be in dead electricity locking and dead electricity is not locked two states.When the length of steel pin (21,22,23) respectively with the through hole 37 that matches, when pin-and-hole 29 is identical with through hole 38 degree of depth, that is: the upper and lower end face of steel pin (21,22,23) respectively with upper flange 12, go up the upper and lower end face of end on articulated jib boss 13 and the lower flange 14 when concordant, fore shaft 1 still is free to swing to extended position under power failure state.Under this dead electricity opening, have only after electromagnetic coil 10 energisings, iron core 25 impels steel pin (21,22,23) to move down, the upper and lower end face that makes steel pin (21,22,23) respectively with upper flange 12, the upper and lower end face dislocation of going up end on articulated jib boss 13 and the lower flange 14, be locked at this position fore shaft 1, and microswitch 15 opened (notice control room door be locked).The another kind of arranging situation of steel pin (21,22,23): long steel pin 21 matches with through hole 38, and short steel pin 23 matches with through hole 37, and steel pin 22 still matches with pin-and-hole 29.At this moment, the upper and lower end face of steel pin (21,22,23) and upper flange 12, the upper and lower end face dislocation of going up articulated jib boss 13 and lower flange 14, fore shaft 1 just can not freely rotate under power failure state, is in the dead electricity locking state.Under this dead electricity locking state, have only after electromagnetic coil 10 energisings, iron core 25 impels steel pin (21,22,23) to move down, and originally moves to concordant with upper flange 12, the steel pin (21,22,23) of going up the upper and lower end face dislocation of end on articulated jib boss 13 and the lower flange 14 respectively.In this position, fore shaft 1 is not locked, and microswitch 15 is opened (notice control room door can be opened).Described detent mechanism by in groove 11 and plant torsion spring 17 bearing pin 16, and bearing pin 16 movingly and the ratchet 18 between groove 11 and lock tongue slot 6, the steel ball 19 that contacts with groove 42 on the ratchet 18 and be positioned at steel ball 1O down and the microswitch 20 of contact constitute.Before dead bolt 41 enters lock tongue slot 6, because the effect of torsion spring 17 offsets a side 34 of ratchet 18 and the end face of elongated slot 36 (being positioned at 11 of lock tongue slot 6 and grooves), at this moment, the cambered surface 43 of ratchet 18 concordant with the notch of lock tongue slot 6 (shown in solid line among Fig. 5).When dead bolt 5 entered in the lock tongue slot 6, dead bolt 5 was depressed ratchet 18, when a side 35 of ratchet being gone to contact with groove surface 44, and ratchet 18 be positioned (shown in double dot dash line among Fig. 5).In ratchet 18 rotation processes, 42 times pressing steel balls 19 of groove are opened microswitch 20 on the ratchet 18, and Door lock with pointing is in closed condition.The shortcoming of above-mentioned patent is that dead electricity locking or not two states conversion difficulty with dead electricity, can not be regulated arbitrarily by the user.

The purpose of the utility model provides a kind of dead electricity locking and does not lock the conveniently adjusted electromagnetism fore shaft of two states with dead electricity.

Technical solutions of the utility model are achieved in that a kind of remote control electromagnetism fore shaft of door lock, by body 1 ', rotating shaft 2 ', fore shaft 3 ', torsion spring 4 ', fore shaft locking device 5 ' and the adjusting device 6 ' formation of a band groove 11 '.It is characterized in that: described fore shaft locking device 5 ' is made of steel pin (51 ', 52 ', 53 '), lockhole cover 54 ', stage clip 55 ', the screw 56 ' of three same thickness, be provided with the upper flange 12 ' of band through hole 13 ' in the groove 11 ', groove 11 ' the upper side wall of described body 1 ' is provided with through hole 14 ', and the handing-over arm 31 ' of going up of fore shaft 3 ' is provided with through hole 32 '.Movable core 64 ' the coaxial core of described three through holes (13 ', 32 ', 14 ') and electromagnetic coil 63 '.Through hole 42 ' is provided with lockhole cover 54 ', and steel pin (51 ', 52 ', 53 ') and stage clip 55 ' are positioned at through hole (13 ', 32 ') and lockhole cover 54 ' and fixing by screw 56 '.Described adjusting device 6 ' is made of adjusting screw(rod) 61 ', stage clip 62 ' and electromagnetic coil 63 ', the side of described electromagnetic coil 63 ' housing is provided with two flanges 64 ', one through hole 65 ' that supplies adjusting screw(rod) 61 ' to go here and there is respectively arranged on the flange 64 ', groove 11 ' the lower wall of described body 1 ' is provided with screw 14 ', and upper flange one side in the groove 11 ' is provided with through hole 15 '.Adjusting screw(rod) 61 ' was gone here and there screw 14 ', two through hole 65 ', stage clip 62 ' and was entered through hole 15 '.

The utility model has the advantages that: the user can be according to intimate needs, and adjusting device 6 is regulated dead electricity locking arbitrarily and dead electricity is not locked two states by regulating.
