Abstract
The utility model discloses a high-efficiency unlocking shift fork, which comprises a shift fork body (1) and a first shift fork head (2), wherein the shift fork body (1) is provided with a locating hole (3) and a second shift fork head (4), the locating hole (3) is fixedly connected with a lock cylinder, and an included angle between the first shift fork head (2) and the second shift fork head (4) is 50 degrees to 75 degrees. By adopting the structure, the defect that the existing mechanical safe-guard chain door lock can be locked or unlocked by being rotated for two circles is overcome, and the high-efficiency unlocking shift fork has the characteristics that the structure is simple, the operation is convenient, the lock can be locked or unlocked by being rotated for one circle, and the like.
Description
Technical field
The utility model relates to a kind of shift fork of unblanking of Mechanical theft-proof door lock, the particularly a kind of shift fork of unblanking that can open Mechanical theft-proof door lock once week that rotates.
Background technology
Mechanical theft-proof door lock is a lock of designing and developing at security door because simple and reasonable, fault rate is low, reliability and theftproof performance is good, reasonable price, unlatching convenient, gone up by extensive door and use in the security door field.But in use there is following shortcoming, key drives the shift fork of unblanking by lock core, the shift fork of unblanking cooperates with the fork slot of dead bolt brace by the shift fork head, key rotates a circle, dead bolt stretches out or withdraws one grade, therefore, no matter locks or unblanks, it is that 720 degree could stretch out dead bolt or withdraw fully that key all must rotate two circles, and brings troublesome poeration to the user; Therefore, how simplifying and lock or the unlock operation structure, also is the primary study object that further improves the Mechanical theft-proof door lock operating characteristics; For this reason, many manufacturers and knowledgeable people have carried out R and D, but do not have rational product to emerge so far as yet.
Summary of the invention
In order to overcome the disadvantage of above-mentioned existence, the purpose of this utility model is by the improvement to the shift fork of unblanking, and a kind of simple in structure, easy to operate, shift fork of efficiently unblanking of rotating a circle and just can unblanking or lock is provided.
The technical scheme that its technical problem that solves the utility model adopts, it comprises shift fork main body, the first shift fork head, the shift fork main body is provided with the locating hole of fixedlying connected with lock core, and described shift fork main body is provided with the second shift fork head, and the angle between the first shift fork head and the second shift fork head is the 50-75 degree.
Described shift fork main body is provided with the 3rd shift fork head, and the angle between the second shift fork head and the 3rd shift fork head is the 50-75 degree.
Be provided with the 3rd shift fork head, the 4th shift fork head and the 5th shift fork head on the described shift fork main body successively, first to the 5th shift fork head is evenly distributed on the shift fork main body.
Be provided with the 3rd shift fork head, the 4th shift fork head, the 5th shift fork head and the 6th shift fork head on the described shift fork main body successively, first to the 6th shift fork head is evenly distributed on the shift fork main body.
After adopting said structure, the utility model has following advantage and effect: the one, and simple in structure, only need on the dead bolt brace, offer and the fork slot that the shift fork number is corresponding and match of unblanking, just can solve the shortcoming that must rotate two circles and just can lock or unblank; The 2nd, adopt said structure, do not need to change the lock body serial verb construction, can not change the technical precaution performance, it is convenient to implement.
