The specific embodiment
Referring to figs. 1 through Fig. 9; A kind of reversible lock fixed blade lock comprises key 1 and tapered end shell 2, in the said tapered end shell 2 lock gall 3 is installed; The afterbody of said lock gall 3 is connected with sword iron 4; The inwall of said tapered end shell 2 is provided with locked groove 5, and said lock gall 3 is provided with some blade grooves 7 radially, and the two ends of said blade groove 7 are provided with the opposite spring mounting hole of opening direction 8; Two spring mounting holes 8 of said same blade groove 7 are separately positioned on the both sides of said blade groove 7; In the said spring mounting hole 8 leaf spring 9 is installed, in the said blade groove 7 to being inserted with two blades 10, the both sides of said key 1 be provided with said blade groove 7 in the corresponding spoon tooth 25 of blade 10.
When the key that does not insert or insert at key 1 does not match all or at least an end of the said blade 10 of a slice surface that is higher than said lock gall 3 be stuck in the said locked groove 5; Lock gall just can not be rotated; The two ends of inserting all said blades 10 of back at the key 1 of coupling are surperficial concordant with said lock gall 3, just can rotate lock gall and unblank.
The spoon tooth 25 of key 1 one sides and the blade of a side 10 constitute one group of unlocking cipher; The spoon tooth 25 of key 1 opposite side constitutes one group of unlocking cipher with the blade 10 of opposite side; This both sides unlocking cipher is separate, and the degree of depth of the teeth of key is calculated according to level Four, and then the unlocking cipher of this lock is 4 14=268435456 kinds, remove invalid combination, can be combined into more than 200,000,000 kind of unlocking cipher; Greatly reduce mutual opening rate, strengthened the safety of lockset, and the length of 7 groups of blade lock galls is identical with 7 traditional blade lock galls; Safe and reliable, have very strong practicality.
Keyhole is by being arranged on the through hole 6 on the lock gall and being arranged on the through hole 6 ' on the blade 10; Constitute; Can position-limit mechanism 24 be set in through hole 6, key can only be inserted and can not oppositely insert by forward, the both sides that perhaps are provided with keyhole are to be arranged to different widths; Different thickness is arranged in the corresponding both sides with key, can prevent that also key from oppositely inserting.
Existing padlock head is after lock gall is extracted the tapered end shell, and blade 10 and leaf spring 9 come off easily, and assembling is trouble comparatively; The blade 10 of the utility model is provided with a limited step 11, is provided with the positive stop lug boss 12 that stops said limited step 11 in the said blade groove 7, when assembling; Utilize the elastic mechanical deformation of blade that blade is inserted in the blade groove 7 by force, after lock gall was extracted the tapered end shell, blade 10 and leaf spring 9 can not come off; Assembling is simple, has improved the reliability of lockset.
Said lock gall 3 is provided with spacing slot 13; Be provided with limit spring installing hole 14 in the said spacing slot 13, in the said limit spring installing hole 14 limit spring 22 be installed, in the said spacing slot 13 limited step 15 is installed; Said key 1 is provided with restriction protrusion 16 corresponding to the position of said limited step 15; Rotate said lock gall 3 after limited step 15 leaves said locked groove 5, the inwall of tapered end shell 2 extruding limited step 15 moves and fastens said restriction protrusion 16, and key 1 can not be pulled out; Limited step 15 during over against locked groove 5 limited step 15 just can under the extruding of restriction protrusion 16, move; Discharge spacing preiection 16, key just can be by plug, guarantee blade snap in blade groove after key extract at same position.
The end that said sword iron 4 connects said lock gall 3 is that 4a is long on one side; The short T-shape of one side 4b; The tail end of said lock gall 3 is provided with a circular recess 17; The T-shape end of said sword iron 4 is installed in the said circular recess 17 through a sword iron circle 23, and said circular recess 17 inwalls are provided with and can drive the step surface 18 that said sword iron 4 rotates.
If the length of T-shape end both sides 4a, 4b is less than the beeline of said step surface 18 to said circular recess 17 axle center; Then step surface 18 can not block T-shape end both sides 4a, 4b; In the lock gall rotating process, can not drive the lock gall rotation unblanks; And if the length of T-shape end both sides 4a, 4b is greater than the beeline of said step surface 18 to said circular recess 17 axle center, then step surface 18 blocks T-shape end both sides, rotates at lock gall just can drive the lock gall rotation less than 90 ° and unblank.
Therefore; With reference to Fig. 6, Fig. 8; The length of the sword iron 4 T-shape ends one side 4a of the utility model is greater than the beeline of said step surface 18 to said circular recess 17 axle center, and the length of opposite side 4b is less than the beeline of said step surface 18 to said circular recess 17 axle center, and the circumference of single dotted line is the rotary motion trace of the short end 4b of sword iron 4 T-shapes among Fig. 6; The circumference of doublet is the rotary motion trace of the long end 4a of sword iron 4 T-shapes; Then step surface 18 can only block 4a one side of T-shape end, and can not block 4b one side of T-shape end, rotates more than 180 ° almost a circle at lock gall and could drive the sword iron rotation and unblank; Can prevent effectively that violence from unblanking, improve the safety of lockset.
