Abstract

This invention relates to a U-shaped mechanical password lock comprising a lock body, a lock hook, a lock latch, a password ring, a password change ring, a retaining gear ring, password teeth, positioning teeth, a positioning bolt, a spring, a pin and a milling mouth, etc. The lock latch is provided with one group of password teeth; the password ring is provided with one password hole and a plurality of trap holes; and one end of the lock latch is provided with the spring. The password hole is made to be on the same straight line with the password teeth through turning the password ring so that the U-shaped mechanical password lock can be opened and closed.

Description

A kind of U-shaped mechanical code lock

Technical field

The present invention relates to a kind of lockset, refer in particular to a kind of U-shaped mechanical code lock.

Background technology

The U-shaped lock of existing motorcycle, electric motor car, bicycle has plenty of to use by of bonding mechanical cipher method to be opened, and these locks are because structure is complicated, and manufacturing cost height, complex structure also bring fault many, so the market adaptability is poor, have certain defective.

Summary of the invention

In order to overcome the defective of existing U-shaped mechanical code lock, the invention provides the U-shaped mechanical code lock of a kind of easy and simple to handle, simple in structure, low cost of manufacture, technology unlocking difficulty.

The technical solution adopted for the present invention to solve the technical problems is: a kind of U-shaped mechanical code lock comprises: lock body, lock hook, locking bolt, tooth road, password circle, change sign indicating number circle, retaining gear ring, password tooth, positioning tooth, positioning bolt, spring, pin, mill composition such as mouth.Establish one group of password tooth on the locking bolt, password number of teeth amount is identical with password number of turns amount.Change the sign indicating number circle and be combined into a password circle with the retaining gear ring, retaining gear ring inner ring is established a code hole, passes through for the password tooth on the locking bolt, establishes many trap holes in addition again, and the trap hole depth is made as 0.3～1mm.One locking bolt hole and tooth road are arranged, for locking bolt move left and right in lock body in the lock body.The locking bolt right-hand member is provided with a spring, plays the effect of locking bolt return.Locking bolt left end end face is established 45 ° of inclined-planes, and 45 ° of inclined-planes are also established in lock hook end face and lock hook hole, cooperates by the 45 inclined-plane lock is opened and closed flexibly.Establish a positioning tooth on the locking bolt, positioning bolt passes the positioning tooth that lock body blocks on the locking bolt and plays the role of positioning.

Every password circle top is provided with a steel ball and spring, produces certain resistance when making rolling password circle.

The invention has the beneficial effects as follows: by above-mentioned design, it is flexible that the U-shaped mechanical code lock is manipulated, and simple in structure, fault is few, technology unlocking is difficult, low cost of manufacture, he is accepted by market easily.

Among the figure 1, lock hook; 2, lock body; 3, locking bolt; 4, spring; 5, steel ball; 6, spring; 7, pin; 8, tooth road; 9, password tooth; 10, password circle; 11, positioning bolt; 12, positioning tooth; 13, change the sign indicating number circle; 14, retaining gear ring; 15, code hole; 16, trap hole; 17, mill mouth.

The specific embodiment

Embodiment 1: the invention will be further described below in conjunction with accompanying drawing, installation process: in Fig. 1, put spring 6 in the lock body, every changes and is inserted in retaining gear ring 14 (setting password figure and position before being inserted in) in the sign indicating number circle 13, be combined into a password circle 10, every password circle 10 is packed in the corresponding hole of lock body, locking bolt 3 from left to right passes every password circle 10 successively from the lock body left side, when passing password circle 10 by its position of roll adjusting code hole 15, make code hole 15 in the retaining gear ring aim on the lock shafts one group of password tooth 9 successively every pass.Insert positioning bolt 11, lock hook 1 is connected by pin 7 with lock body 2, and assembling is finished.

Use: when Fig. 1 blocking, aim at set password, the code hole 15 that the password tooth 9 on the locking bolt is aimed on each password circle by rolling password circle 10, extract lock hook 1, lock hook hole and locking bolt end face are under 45 ° of ramp effect, and locking bolt 3 moves right, and lock be opened (as Fig. 2).

In Fig. 2, aim at password equally, depress lock hook 1, locking bolt 3 moves right, return under the tension force effect of spring 6 then, locking bolt and lock hook hole close up locking, and this moment, positioning bolt 11 blocked positioning tooth 12 location (as Fig. 1), the password circle can arbitrarily rotate, and dials random password, is blocking.

Every password circle top is provided with a steel ball 5 and spring 4, produces certain resistance when making rolling password circle.

Change a yard process: after aiming at password, take out lock shaft 3, take out password circle 10, after changing sign indicating number circle 13 and being reassembled into the new password numeral, reinstall, change and yard finish by embodiment 1 (installation process) with retaining gear ring 14.

Embodiment 2: as Fig. 4, establish one on the lock body and mill mouth 17, but positioning bolt 11 is move left and right in milling mouth 17, positioning bolt 11 is by milling in mouthful 17 reeve locking bolts 3, pass through manually pulling positioning bolt 11 during use, locking bolt 3 is moved right, reach the purpose of manually unblanking, other uses are identical with embodiment 1.
