Abstract
The utility model discloses a mechanical coded lock, which comprises a lock rod (1), a lock arm (7) and a code locking mechanism, wherein the lock arm (7) is hinged to one end of the lock rod (1); the other end of the lock rod (1) is provided with a lock rod locking hole (10); a movable end of the lock arm (7) is matched with the lock rod locking hole (10); the code locking mechanism comprises a shifting wheel bracket (2), a plurality of coded shifting wheels (3) and a lock sleeve (6); the shifting wheel bracket (2) and the lock sleeve (6) are sequentially sleeved on the lock rod (1) and are fixedly connected with each other; the coded shifting wheels (3) are rotationally arranged in parallel on the lock rod (1) inside the shifting wheel bracket (2); shifting wheel notches (4) are formed in central holes of the coded shifting wheels (3); and lock head lugs (5) matched with the shifting wheel notches (4) are arranged on the lock rod (1). By adoption of the structure, the mechanical coded lock has the characteristics of simple and reasonable structure, convenience in operation and use, low production cost, high anti-theft performance and the like.
Description
Technical field
The utility model relates to a kind of mechanical code lock, particularly a kind of mechanical code lock that is used for bicycle.
Background technology
Development along with society; Growth in the living standard, bicycles such as motorcycle, electric motor car, bicycle have been popularized, and the phenomenon of stealing bicycle but takes place repeatedly; Stolen in order to prevent bicycle, many people increase a U type inserted link lock again on the basis of original lockset.U type inserted link lock comprises lock body, lock core, U type inserted link and locking bar, needs to insert lock core with key when unblanking and drives the locking bar rotation, pulls out U type inserted link and accomplish and unblank again.Though the theftproof performance of U type inserted link and locking bar is better, because the lock core of U type inserted link lock adopts conventional lock core, the thief is easy to open with the mode of technical opening, causes U type inserted link lock not have the effect of antitheft.People have developed mechanical code lock for this reason; Though mechanical code lock can play anti-technical opening; Improved theftproof performance greatly; Also avoid leaving behind the inconvenience that key or key loss are brought, just can open mechanical code lock as long as remember unlocking cipher, but the existing mechanical coded lock also exists problem such as complex structure, production and processing difficulty are big, cost of production height.For this reason, many manufacturers and knowledgeable people research and develop to the problems referred to above, but do not have desirable product on market, to emerge so far as yet.
Summary of the invention
For overcoming the above-mentioned disadvantage that the existing machinery coded lock exists, the purpose of the utility model provides a kind of simple and reasonable, easy for operation, cost of production is low, theftproof performance is good mechanical code lock.
The utility model solves the problems of the technologies described above the technical scheme that is adopted; It comprises locking bar, hammerlock, password locking mechanism, and hammerlock is hinged on an end of locking bar, and the other end of locking bar is provided with the locking bar lockhole; The movable end of arm matches with the locking bar lockhole; Described password locking mechanism comprises thumb wheel support, several password thumb wheels, lock tube, and thumb wheel support and lock tube are set on the locking bar successively and are mutually permanently connected, and described password thumb wheel is arranged side by side on the locking bar in the thumb wheel support rotationally; The centre bore of password thumb wheel is provided with the thumb wheel notch, and locking bar is provided with the tapered end projection that matches with the thumb wheel notch.
The further scheme of the utility model, the side plate central hole size of said thumb wheel support is less than the tapered end projection.
The utility model is scheme further, and described lock tube is provided with the lock tube lockhole, and hammerlock is provided with the locked groove that matches with the lock tube lockhole.
The utility model is scheme further, and described locking bar is provided with the guide chute that prevents that the thumb wheel support from rotating.
After adopting said structure; With prior art following advantage and effect are arranged relatively: when unblanking, have only tapered end projection on the thumb wheel notch of all password thumb wheels and corresponding locking bar, just can be moved to the left thumb wheel support and lock tube on time; Lock tube is separated with locked groove on the hammerlock; Unblank thereby open the hammerlock completion, unlocking cipher does not know just can't unblank, and has advantages such as simple in structure, easy for operation, that theftproof performance is good.

The specific embodiment
Fig. 1, Fig. 2 and shown in Figure 3 are the specific embodiments of a kind of mechanical code lock of the utility model, and it comprises locking bar 1, hammerlock 7, password locking mechanism; Hammerlock 7 is hinged on an end of locking bar 1, and the other end of locking bar 1 is provided with locking bar lockhole 10, and the movable end of arm 7 matches with locking bar lockhole 10; Described password locking mechanism comprises thumb wheel support 2, several password thumb wheels 3, lock tube 6; Password thumb wheel 3 is many more, and theftproof performance is good more, operated by rotary motion four or more; Thumb wheel support 2 is set on the locking bar 1 successively with lock tube 6 and is mutually permanently connected; Described password thumb wheel 3 is arranged side by side on the locking bar 1 in thumb wheel support 2 rotationally, and the centre bore of password thumb wheel 3 is provided with thumb wheel notch 4, and locking bar 1 is provided with the tapered end projection 5 that matches with thumb wheel notch 4.
In order to prevent that thumb wheel support 2 from deviating from from locking bar 1, the side plate central hole size of said thumb wheel support 2 is less than tapered end projection 5, and tapered end projection 5 plays position-limiting action.Solid and reliable in order to guarantee after the locking, described lock tube 6 is provided with lock tube lockhole 9, and hammerlock 7 is provided with the locked groove 8 that matches with lock tube lockhole 9.In order to prevent that thumb wheel support 2 from rotating relative to locking bar 1, described locking bar 1 is provided with guide chute or the guide pad that prevents that thumb wheel support 2 from rotating.
