Referring to figs. 1 to Fig. 3, this is embodiment a1 of the new lockset of this practicality, specifically：
A kind of lockset multiple safety structure, including lock tube 1, is provided with the lock tube through hole extending from top to bottom in lock tube 1, also include locking
Tongue 2, end block 3 and clamping part, end block 3 is located in lock tube through hole, and dead bolt 2 extends from top to bottom, and end block 3 is provided with dead bolt and leads to
Hole, dead bolt 2 is extended downwardly from after dead bolt through hole, and end block 3 is fixedly connected with lock tube 1, is provided with rotation between end block 3 and dead bolt 2
Gap；It is provided with least two barrier sheets in lock tube through hole, respectively goes up barrier sheet 301 and lower barrier sheet 302, two barrier sheets are equal
It is located at the top of dead bolt 2, two barrier sheets are equipped with the key core via 303 linking together and key wing via 304, lock
The rotary shaft of tongue 2 passes through lock core via, and key wing via 304 tongue is in the side of described rotary shaft, the key wing of upper barrier sheet 301
Via 304 is overlapped with the key wing via 304 on lower barrier sheet 302 after rotating 1 degree to 179 degree with described rotary shaft for axle；On
Barrier sheet 301 is fixedly connected with lock tube 1, and lower barrier sheet 302 can be rotated with described rotary shaft for axle in lock tube through hole.Lock core
Key part is normally located on the hole wall of lock tube through hole, because upper barrier sheet and lower barrier sheet have certain drift angle, and
Therefore lawless person can only see the region of key core via 303 this point point, the key wing via of lower barrier sheet 304 due to having on
The stop of barrier sheet, the cryptographic structure down of following barrier sheet be blocked, lawless person cannot be understood by observing
The structure of lock core, improves confidentiality and the security of lockset.
Limiting stand 101 is provided with least one axially extending bore 201, end block 3 be provided with identical with axially extending bore 201 quantity and
The corresponding spacing hole in position 202, is equipped with described locking member 203, all of spacing hole 202 in all of spacing hole 202
Inside it is equipped with back-moving spring 204, back-moving spring 204 is located at the lower section of locking member 203 so that locking member 203 can be from spacing
Enter axially extending bore 201 in hole 202, and make the upper end of locking member 203 be in locking member 203 in axially extending bore 201
Lower end is in spacing hole 202.So, limiting stand just can be linked together by locking member with end block, and prevents dead bolt from rotating,
Only carry in the key insertion lock tube through hole at press-in end, rely on press-in end to press down locking member, allow locking member to leave
Axially extending bore, thus discharging limiting stand, due to and be pressed into end insertion axially extending bore in, rotation key just can allow dead bolt rotate, reality
Now unlock.
The upper end of dead bolt 2 is provided with limiting stand 101, and limiting stand 101 is located at the top of end block 3 and is located at lower barrier sheet 302
Lower section, the maximum transverse size of limiting stand 101 is more than the maximum transverse size of dead bolt through hole；The outside of limiting stand 101 is provided with
Card access surface 1011, clamping part is provided with Access Division 1021 and drive division 1022, Access Division 1021 and the drive division of mutual linkage
1022 are each provided in lock tube through hole, and the side of Access Division 1021 can be abutted with card access surface 1011 and lock dead bolt 2, drive division 1022
Axial direction to dead bolt 2 rotating shaft stretches out, and the extension elongation of drive division 1022 is abutted with card access surface 1011 more than Access Division 1021
Horizontal abutting length so that the displacement of drive division can drive Access Division to leave card access surface.The key being adapted to drive division is inserted
Enter in lock tube through hole, by drive division jack-up, because being linked with drive division in Access Division, therefore Access Division departs from card access surface to key, yes
Dead bolt can rotate.
The clamping part of the present embodiment is elastomeric element, and it is metal plate punching part or working of plastics, metal plate punching part or plastics
Part has elasticity, and this just allows and enables to link with the Access Division 1021 on clamping part and drive division 1022, arranges on the key
The jacking part being adapted with drive division 1022, jacking part, by drive division 1022 jack-up, just can allow Access Division 1021 discharge dead bolt.
For ease of installing, the clamping part of the present embodiment is integrally provided in lock tube through hole, the clamping part tool of the present embodiment
The external part that the two symmetrically arranged entirety in left and right extends downwardly, Access Division 1021 and drive division 1022 is had to be each provided at external part
On, drive division 1022 is located at the top of Access Division 1021.
The upper end end face of limiting stand 101 is provided with key portion 105 that protrude upward or concave downward, key portion 105
Cross section has base shape, increases cross section raised and/or that depression is formed, described basis on the edge of base shape
Generally circular in shape or polygon, the rotating shaft of dead bolt 2 passes through described base shape, thus can connect key portion by key and make
Dead bolt rotates, and the as shown in Figure 3 dotted line circle being connected with key portion 105 is described base shape.
With reference to Fig. 4 to Fig. 6, this is embodiment a2 of lockset of the present invention, specifically：
This is the improvement done on the basis of embodiment a1, and because elastomeric element entirety material is relatively thin or softer, this is for some
For small-sized lockset, locking intensity is not just much of that, therefore the clamping part of the present embodiment is rigid member, and clamping part is in horizontal stroke
To setting, Access Division 1021 and drive division 1022 stretch out from the left side hole wall of lock tube through hole.
Clamping part can realize the reset of drive division using gravity, but which limits lockset installation direction,
For the ease of solving such problem, the present embodiment also includes compressing spring 103, compresses the left side that spring 103 is located at clamping part
Side is simultaneously abutted with clamping part.
The present embodiment also includes the driving piece 104 being located in lock tube through hole, drive piece 104 can around the axis of rotation of dead bolt 2,
Drive piece 104 to be provided with and lift face and the landing face near described rotating shaft away from described rotating shaft, drive division 1022 can be with the face of lifting
Or landing face abuts, thus allow and separating between Access Division 1021 and card access surface 1011 or abut.Which provides a kind of and real
Apply the jack-up mode of the different drive division of an a1 1022.The setting driving piece advantageously reduces the abrasion of key, also allows this enforcement
Example is more durable.As shown in figure 5, the piece 104 that drives of the present embodiment has the section of ellipse, the less lift of upper and lower both sides arc rate
Rise face, and the arc rate of the left and right sides larger for land face.
Above the better embodiment of the present invention is illustrated, but the invention is not limited to described enforcement
Example, those of ordinary skill in the art also can make a variety of equivalent modifications without prejudice on the premise of present invention spirit or replace
Change, these equivalent modifications or replacement are all contained in the application claim limited range.
