(5). during＜B1 〉=270 ° during with＜B1 〉=90 ° roughly the same.
(6). can find out from above several specific positions: any position of 0 °～360 °,＜B〉can also can lead to＜C〉with＜A〉is logical＜B1 〉, and still＜B〉but can not be logical simultaneously with＜A 〉,＜C 〉.
(7). conclusion: by the rotation of mandrel component 0201, key is free to put into, withdraws from the spoon position.Because the cutting function of mandrel component 0201 and other component, make＜A 〉,＜C〉all obstructed in any position, effectively prevented from using steel wire, master key or special tool to stir the skilled unlocking of pellet.
2. key is built in the lock entirely
Key 0209 is vital part of the present invention, and it has following significant feature:
(1). key 0209 all places the inside of lock in work, its shape only is equivalent to the tooth flower part of traditional key front portion, does not have the handle portion at the rear portion of traditional key.Pair spoon function is only arranged in use, and can not transmit the driving force of unblanking of hand.The driving force of unblanking is driven mandrel component 0201, key 0209, spoon pellet 0213, mandrel overcoat 0211, push rod 0501 and shift fork body 0503 is carried out the open and close lock by handle 0206, Handle axis 0208 by hand.Its function is equivalent to the handle portion at traditional key rear portion.
(2). as shown in figure 11: key 0209 adopts the shape on the fan-shaped face of cylinder, by y, z, α ° and four parameters controls of billiards diameter tooth flower position to spoon pellet 0213.
(3). as shown in figure 12: key 0209 adopts the arrangement mode of babysbreath, so just can be at y, z, arrange very flexibly pellet under the control of α ° and four parameters of billiards diameter, this mode has changed the mode of traditional key straight line pellet, be a fan-shaped face of cylinder with the expanded range of arranging pellet, position that almost can arbitrary layout pellet on this face, increased greatly the permutation and combination number of key, the skilled unlocking person who adopts the tinfoil unlocking method has not been increased very large technical difficulty in the situation that there is original key to prepare the tinfoil key embryo.
(4). as shown in figure 13: the special case of arranging as babysbreath, to spoon pellet 0213 also can adopt common be arranged as row arrangement mode, can adopt 1 row, 2 row ... N row, 1 row, 2 rows ... N row's spread pattern.
(5). key 0209 uses the shape of key among Figure 12, Figure 13 usually, but does not get rid of the possibility that adopts other shapes, is exactly a kind of schematic diagram that adopts the conventional shape key such as Figure 14.
(6). as shown in figure 15: owing to packing into and withdraw from the needs of key, processed big groove 0209a and little groove 0209b at the back side of key 0209, outer, the inner face of big groove 0209a are respectively 0209c, 0209d.We have processed large boss 0208a and small boss 0208b on Handle axis 0208, and outer, the inner face of large boss 0208a are respectively 0208c, 0208d, and the outer face of small boss 0208b is 0208e.
(7). drive mandrel component 0201 rotation with handle 0206, when the key standing groove 0204a of the key insertion hole 0401a on the outer lock body 0401 and mandrel plug 0204 is obstructed, the front end face of mandrel component 0201 is cut off the key insertion hole 0401a on the outer lock body 0401 fully, this moment, 0401a just became a blind hole, can not enter from here the inside of lock again.
3. the packing into and withdraw from method of key:
Because the key lock body inside of need to all packing into, thus can not use the conventional direct-insert method of hand-held key, for this reason specialized designs of the present invention packing into and drawing-out mechanism of key.It is as follows that we describe its operating principle in detail in conjunction with Handle axis assembly 0205, key 0209, mandrel component 0201 and outer lock body 0401:
(1). the axle sectional view of the above-mentioned part when Figure 16 is exactly 0 ° in the home position of lockset locking.
(2). the key step 1 of packing into: such as Figure 17, shown in Figure 15: outwards light handle 0206, meet the inner face 0204b of mandrel plug 0204 to the outer face 0208c of the large boss 0208a of Handle axis 0208 till.
(3). the key step 2 of packing into: such as Figure 18, shown in Figure 15: with handle 0206 Rotate 180 °, the slotted hole of key insertion hole 0401a aligns on the key standing groove 0206a on this moment handle 0206 and the outer lock body 0401.The center line of key insertion hole 0401a aligns on the center line of the small boss 0208b outer face 0208e of Handle axis 0208 and the outer lock body 0401.
(4). the key step 3 of packing into: such as Figure 19, shown in Figure 15: key 0209 key insertion hole 0401a from the outer lock body 0401 is packed into, meet the small boss 0208b outer face 0208e of Handle axis 0208 to the outer face 0209c of key 0209 back side big groove 0209a till.
(5). the key step 4 of packing into: such as Figure 20, shown in Figure 15: with handle 0206 Rotate 180 °, this moment Handle axis 0208 the center line of outer face 0208c of large boss 0208a and the central lines of the outer face 0209c of key 0209 back side big groove 0209a.
(6). the key step 5 of packing into: such as Figure 21, shown in Figure 15: push inward fixed handle 0206.Because the large boss 0208a inner face 0208d of Handle axis 0208 is larger than the little groove 0209b in key 0209 back side, so the inner face 0208d of the large boss 0208a of Handle axis 0208 is mobile inwards together by the inner face 0209d promotion key 0209 of key 0209 back side big groove 0209a.
(7). at this moment, key is packed into and is finished, if will withdraw from key, only needs to press aforesaid operations step reverse operating and gets final product.
4. the operating principle of detent mechanism:
General security door needs lockset to rotate for 2 weeks to carry out the open and close latching operation.We have designed detent mechanism for this reason.This mechanism is made of positioning turntable 0304, pin 0212 and alignment pin 0305, and positioning turntable 0304 is installed in 0301 back, pellet cabin, and pin 0212 is installed on the mandrel overcoat 0211, and pellet cabin 0301 is fixed on the outer lock body 0401.
As shown in figure 22: in the time of 0 ° in the home position of lockset locking, alignment pin 0305 is positioned at the right limit point of the arc groove 0304a on the positioning turntable 0304, and pin 0212 is positioned at the straight trough 0304b bottom on the positioning turntable 0304.Arc groove 0304a on the positioning turntable 0304 only allows positioning turntable 0304 to be rotated counterclockwise at this moment, and mandrel overcoat 0211 also can only be by the rotation of diagram clockwise direction.
As shown in figure 23: when 0211 rotation of mandrel overcoat, pin 0212 is stirred the straight trough 0304b rotation on the positioning turntable 0304, after rotating to an angle, the pin 0212 straight trough 0304b that leaves on the positioning turntable 0304, the cylindrical of the groove 0211b of mandrel overcoat 0211 pins positioning turntable 0304 upper outside arc-shaped surface 0304c at this moment, and positioning turntable 0304 can not be rotated.This figure is the detent mechanism schematic diagram of mandrel overcoat 0211 rotation during to 180 °.
As shown in figure 24: pin 0212 rotates 360 °, stir positioning turntable 0304 and rotate a tooth, when mandrel overcoat 0211 rotates to 720 °, alignment pin 0305 is positioned at the left limit point of the arc groove 0304a on the positioning turntable 0304, mandrel overcoat 0211 can not continue the clockwise direction rotation again, and unlock operation is finished.During lock operation, mandrel overcoat 0211 can only rotate counterclockwise next time, and this figure is exactly the detent mechanism schematic diagram of mandrel overcoat 0211 rotation during to 720 °.
