Abstract

A bicycle cipher lock with high anti-theft performance comprises a cipher lock (4). A pin (5) is arranged under the cipher rotary plate (42) of the cipher lock, a lock core (7) is arranged under the pin (5),a stake (72) is arranged at the front end of the lock core(7), a handle (71) is arranged at the lower part of the lock core (7) and a notch is a bevel in front (73) on the rear part of lock core (7), corresponding to the lower end of the pin (5). The utility model is the anti-theft cipher lock for the bicycle and the electric bicycle.

Description

The bicycle coded lock

Technical field

The utility model relates to a kind of coded lock, particularly is matched in the coded lock of bicycle.

Background technology

Existing bicycle lock has large in the variety, but usually all is that lock pin exposes and adopts key operated lock.This bicycle lock theftproof performance is not high enough, often has the bicycle of keyed to be taken place by the phenomenon of striking lock or unblanking to steal.

Summary of the invention

It is not high that the utility model will solve existing bicycle lock theftproof performance, and bicycle is stolen problem easily, and a kind of bicycle coded lock of the present utility model is provided for this reason, and this lock can assemble installation, theftproof performance height when bicycle is made.

For addressing the above problem, the technical solution adopted in the utility model is provided with a trick lock, its special character is to be provided with a pin below the password rotor of described trick lock, be provided with a lock core below the pin, this lock core front end has inserting column, the lock core bottom is associated with handle, and having the front side above the lock core rear portion is the lower end of the recess on inclined-plane corresponding to described pin.

The utility model should be with anti-self-locking spring on the inserting column of described lock core front end.

Described trick lock is the tapered end in the prior art, and it has rotating disk and password rotor.When rotating disk turns to the password place of setting for the first time, the first password rotor turns to its notch alignment and sets position S; Rotating disk turns to the setting code place for the second time, and the second password rotor turns to its notch alignment and sets position S; Rotating disk turns to the setting code place for the third time, and the 3rd password rotor turns to its notch alignment and sets position S.During the same position S of the notch alignment of three rotors, lock is in the shape that can be unlocked.It can be clockwise direction that its turntable rotates for the first time, and rotating for the second time then is anticlockwise direction, rotates for the third time to be clockwise direction.

Pin in the utility model is corresponding to the password rotor.When the breach of three block encryption rotors during over against pin, pin can penetrate breach, makes lock be in the shape that can be unlocked.

Lock core in the utility model is at lock can be moved a distance can be unlocked state the time, realizes unblanking or locking.

The utility model is installed in bicycle, is to install when bicycle tripod and front fork manufacturing formation.

The utility model is owing to be provided with trick lock and lock core, only just can unblank knowing under the situation of password, so the utility model theftproof performance height is a kind of new lock that is fit to be assemblied in bicycle, electric bike.

Fig. 3 is that the utility model is installed on the bicycle view.

The specific embodiment

The bicycle coded lock, has the trick lock 4 that constitutes by rotating disk 41, password rotor 42 and shell etc., below the password rotor 42 of trick lock, be provided with a pin 5, be provided with a lock core 7 below the pin 5, this lock core front end has inserting column 72, the lock core bottom is associated with handle 71, and having the front side above the lock core rear portion is the lower end of the recess on inclined-plane 73 corresponding to described pin 5, is with anti-self-locking spring 2 on the inserting column of lock core front end; Having adapter plate 3 below the tapered end 4 combines fixing with tapered end.

The utility model is installed on bicycle, is to install when the spider of bicycle and front fork designing for manufacturing assembling.Described adapter plate 3 is incorporated into above the spider crosspiece 6 near front fork 1 place, tapered end 4 combines fixing with adapter plate 3, lock core 7 is installed in the crosspiece 6, have the corresponding pin 5 of through hole on crosspiece 6 upsides and the adapter plate 3, the crosspiece downside has notch 61, and the handle 71 of lock core is positioned at notch, and bicycle front fork 1 has through hole 11, it is corresponding with it also to have through hole before the spider on the support shelves, and the lock core front portion has inserting column 72 corresponding to through hole 11.

As shown in Figure 1, lock core 7 reach, inserting column 72 penetrates through hole 11, pin 5 falls into the recess on tool inclined-plane 73 on the lock core, password rotor 42 breach misplace with pin 5, pin 5 can not on move, lock core 7 promptly can not by after move, bicycle is lockable.

As shown in Figure 2, after rotating disk 41 rotates by the password of setting, the notch alignment pin 5 of three block encryption rotors 42, pin 5 can on move; According to notch 61 after move lock core 7 by handle 71 this moment, pin 5 along inclined-plane 73 move and on move the breach that passes password rotor 42, inserting column 72 withdraws from the through hole 11 in front fork, lock is unlocked.

The effect of anti-self-locking spring 2 is to unblank shape in use when the bicycle place, and lock core 7 can not move forward and locking automatically.The elastic force of anti-self-locking spring 2 is designed to be as far as possible little, can prevent that lock core from moving forward just automatically.

Claims

1, bicycle coded lock, has a trick lock (4), it is characterized in that below the password rotor (42) of described trick lock, being provided with a pin (5), be provided with a lock core (7) below the pin (5), this lock core front end has inserting column (72), the lock core bottom is associated with handle (71), and having the front side above the lock core rear portion is the lower end of the recess on inclined-plane (73) corresponding to described pin (5).

2, bicycle coded lock as claimed in claim 1 is characterized in that being with anti-self-locking spring (2) on the inserting column of described lock core front end.
