Abstract
The utility model relates to a cipher lock, in particular to an anti-theft cipher lock, which is composed of a shell body, an inner and an outer transit rods, an all-gear, a semi-gear, an inner and an outer transit rod handles and a transit rod handle, an intercepting column, a spring column, a spring and the like, wherein the all-gear and the semi-gear are engaged with each other, the all-gear is provided with a rod groove for inserting the outer transit rod, the semi-gear is provided with a locating hole for flipping into a spring head, and an inner transit rod spring is arranged between the inner transit rod handle and the outer transit rod handle. During the use of the cipher lock, when a person pulls the inner transit rod handle inwards inside a room, the spring of the inner transit rod is compressed, and a lock on the inner transit rod is retracted, thereby the lock is in an unlocking state. When a person pulls the semi-gear to the cipher numbers outside the room, the semi-gear drives the all-gear to rotate, when the rod groove is rotated on the position of the outer transit rod, the person pulls the outer transit rod handle, thereby the outer transit rod is inserted into the rod groove, and the inner transit rod moves to the left following the outer transit rod, and the lock is retracted, and thereby the cipher lock is in an unlocking state. The utility model has the advantages of safety, simple operation and low cost.
Description
Technical field
The utility model relates to a kind of coded lock.
Background technology
Present coded lock, structure has various ways, such as by being made up of handle wheel and body lock, the handle wheel design has button, has in the body lock and the same disk of conventional cipher lock, during open operation, the turning handle wheel, all passwords are all followed commentaries on classics, push button, and the combination disk of the corresponding control of this button just stops operating, each combination disk is represented one group of password value, in the process that combination disk stops, there is not the precedence rule, have only the password size order of combination disk representative.These coded locks all exist complex structure, easy damage, cost height, the problem that can not use on door.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide a kind of safe in utilization, simple to operate, anti-theft puzzle lock that cost is low.
The implementation of the utility model purpose is, anti-theft puzzle lock, outer current bar 2, interception post 8, spring stack 19, the full-depth tooth wheel shaft 9 of dress full-depth tooth wheel 4, half gear shaft 10 of adorning half gear 12 is contained on the housing 1, the full-depth tooth wheel, half gears engaged, housing has the tooth mouth 15 that exposes half gear teeth, interior current bar 3 is contained in the outer current bar 2, outer current bar 2 has outer current bar handle 17, interior current bar 3 has current bar handle 6, the full-depth tooth wheel has the roofbolt groove 7 that inserts outer current roofbolt 5, the locating hole 13 that half gear 12 has bullet 14 to spring into, there is spring 16 bullet 14 inboards, between interior current bar 3 and the outer current bar handle 17 the interior bar spring 18 that passes through is arranged, between spring stack 19 and the housing 1 outer spring 20 is arranged.
When using the utility model, the people only need inwardly stir interior current bar handle 6 as in doors, current bar spring 18 in interior current bar 3 compressings, the tapered end on the interior current bar 3 is withdrawn, and the utility model is in unlocking condition, current bar handle 6 in unclamping, interior current bar spring 18 returns, lock is locked again.As the people without, stir half gear 12 to the password number, half gear driven full-depth tooth wheel 4 rotates, outside forwarding to, roofbolt groove 7 during the position of current roofbolt 5, stirs outer current bar handle 17 left, compression outer spring 20, outer current bar 2 drives outer current roofbolt 5 and inserts in the roofbolt groove 7, in current bar 3 thereupon left, the tapered end withdrawal on the interior current bar 3, the utility model is in unlocking condition.
The utility model is safe in utilization, simple to operate, cost is low.
Description of drawings
Accompanying drawing is the utility model structural representation
The specific embodiment
With reference to accompanying drawing, the utility model is by housing 1, inside and outside current bar 3,2, full-depth tooth wheel 4, half gear 12, interior current bar handle 6, current bar handle 17, interception post 8, spring stack 19, spring etc. are formed outward.The locating hole 13 that the full-depth tooth wheel has roofbolt groove 7, half gears of the outer current roofbolt 5 of insertion to have bullet 14 to spring into has interior current bar spring 18 between interior current bar 3 and the outer current bar handle 17.
The utlity model has anti-theft feature for making, full-depth tooth wheel 4 has antitheft hole 11, and is inaccurate as the making of full-depth tooth wheel, when swinging, plays antitheft effect.
When using the utility model, the people only need inwardly stir interior current bar handle 6 as in doors, current bar spring 18 in interior current bar 3 compressings, the tapered end on the interior current bar 3 is withdrawn, and the utility model is in unlocking condition, current bar handle 6 in unclamping, interior current bar spring 18 returns, lock is locked again.As the people without, stir half gear 12 to the password number, half gear driven full-depth tooth wheel 4 rotates, outside forwarding to, roofbolt groove 7 during the position of current roofbolt 5, stirs outer current bar handle 17 left, compression outer spring 20, outer current bar 2 drives outer current roofbolt 5 and inserts in the roofbolt groove 7, in current bar 3 thereupon left, the tapered end withdrawal on the interior current bar 3, the utility model is in unlocking condition.
