The mechanical code tapered end
Technical field
The present invention relates to a kind of trick lock.
Background technology
The form of structure of existing machinery cylinder lock set is last 100 years history so far, very be familiar with and understand by people, the method cracked emerges in an endless stream, unlocking tool is also of all shapes and colors, this monistic latch-up structure form, the defect of existence is that safety index and the size of key of lockset is low, the robber in flagrant delict can go smoothly easily, theft case happens occasionally, and people's safety perception is to threatening greatly.
The electronic cipher latching operation is too loaded down with trivial details, and old children is unsuitable, does interference performance and poor stability.
The complex structure of conventional cipher tapered end, fault rate is high, becomes code operations very loaded down with trivial details, and the feel of operation is poor.
Summary of the invention
For above-mentioned problem, the invention provides a kind of mechanical code tapered end, it integrates the mechanical billiard locking, password night lock is determined mechanism, dependable performance and password accurate positioning.
The present invention is achieved in that the feature of mechanical code tapered end is: the center of tapered end is provided with lock core, the edge of the tapered end combination disk that distributing, the other sign that is provided with of the combination disk of tapered end; Back seat is enclosed within the rear portion of lock core, and the one end is close on the end face of tapered end, and its other end is connected with bolt plate through screw; Described combination disk, after dish, the screw thread of front-end of spindle is screwed in the screw of tapered end, spacing by collar, the bar of rear-end of spindle is inserted in the axis hole of tapered end, the rear-end of spindle face be arranged in the back seat axis hole and offseted by the pellet of spring-advance.
In addition, the surface of combination disk is provided with graduation mark.
Also establish cylinder device between lock core and tapered end, must be by key operated.
The screw thread of front-end of spindle or be multiple thread.
Effect of the present invention is:
1. it integrates mechanical billiard locking, password locking mechanism, only when key and password are all correct, could open, and be difficult to judge to be that key or the setting of that combination disk are incorrect and can not open in practicality, therefore the safety of tapered end is high.
Mechanical billiard locking mechanism very reliable operation is fast, meet the inveteracy custom of unblanking of people.
3. password night lock is determined the mechanical billiard latch-up structure that mechanism adopts the screw thread location, the high and good hand touch of its sensitivity, compare the ordinary password tapered end it have that structure is simple and direct, failure rate is low, inextricably involved feature.
4. the structure of Purely mechanical, do not exist the problem of interference and stability and good.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the sectional view of mechanical code tapered end of the present invention.
Fig. 2 is the elevation of mechanical code tapered end of the present invention.
In figure: 1. main shaft, 2. collar, 3. tapered end, 4. pellet, 5. spring, 6. screw, 7. bolt plate, 8. back seat, 9. combination disk, 10. lock core, 11. signs.
The specific embodiment
As shown in the figure, the center of tapered end 3 is provided with lock core 10, between lock core 10 and tapered end 3, also establishes cylinder device, must be by key operated; The edge of tapered end 3 combination disk 9 that distributing, the other sign 11 that is provided with of the combination disk 9 of tapered end 3, the surface of combination disk 9 is provided with graduation mark; Back seat 8 is enclosed within the rear portion of lock core 10, and the one end is close on the end face of tapered end 3, and its other end is connected with bolt plate 7 through screw 6.
Described combination disk 9, after dish, the screw thread of main shaft 1 front end is screwed in the screw of tapered end 3, the screw thread of main shaft 1 front end is coarse pitch head thread or multiple thread, spacing by collar 2, the bar of main shaft 1 rear end is inserted in the axis hole of tapered end 3, main shaft 1 rear end face be arranged in the pellet 4 that back seat 8 axis holes advance by spring 5 and offset.
This trick lock is fixed in door by traditional method.
Structure of the present invention is not limited to the described form of embodiment, and the further expansion that those of ordinary skill in the art makes according to the present invention all falls into protection scope of the present invention.
Mechanical code tapered end of the present invention is applicable to Modern Family very much to be used.
