Abstract

The utility model relates to a bicycle lock, which is composed of a lock rod 1, a lock 4, and lock cores 5, 6, wherein the lock rod 1 is U-shaped, and break angles alpha on both edges are from 75 DEG to 150 DEG. Both sides are respectively made into an insertion rod 2 of a cylindrical lock rod and a lock protecting rod 3 with a semicircle section, and the middle part of the insertion rod 2 of a cylindrical lock rod and the middle part of the lock protecting rod are provided with long grooves. The front end of the insertion rod 2 of the lock rod is provided with a fastener, and the lock 4 is rectangular. One end surface of the lock 4 is provided with an insertion hole 7 having the equal distance and diameter with the distance and diameter of each of the insertion rods 2 of the two lock rods. The bottom and one side edge corresponding to the insertion hole 7 are respectively fixed with two mutually vertical conventional lock cores 5, 6. The utility model has the advantages of simple structure, shapely figure, convenient use, double protection of the two lock cores, and high safety and can be widely used for bicycles of various kinds; the bicycle lock is difficult to pry off.

Description

Bicycle lock

Technical field:

The utility model belongs to the lock class, particularly relates to a kind of destroyed bicycle lock as safe as a house that is difficult for.

Background technology:

As everyone knows, the bicycle lock of selling on the market is of a great variety at present, the lock that wherein has kind of locking bar to combine with lock body, because of the both sides of U font locking bar openend are straight flange, after inserting lock body, thus very easily pried open because of origin of force is many, in addition, because of being that the monolock core has only a key to be opened easily, so provide convenience for the car stealer.

Summary of the invention:

Main purpose of the present utility model is: overcome above deficiency and a kind of bicycle front fork and front axle of making full use of is provided, during the lock car, lock and front fork and front axle can closely cooperate, when wanting to destroy lock, and the bicycle lock that the difficult quilt of no origin of force is pried open.

The technical scheme that its technical problem that solves the utility model adopts is: it is by locking bar; lock body; lock core is formed; it is characterized in that: locking bar 1 is the U font for circular cross section integral body; openend is converted into certain angle α; its α angle is 75 °≤α≤150 °; the lock body guard bar 3 of cylindrical locking bar inserted link 2 and semicircle section is made at the knuckle place respectively; elongated slot is left in centre at them; the front end of cylindrical locking bar inserted link 2 has a buckle; lock body 4 is a cuboid; have two and locking bar inserted link 2 corresponding jacks 7 on one end; be fixed with two mutually perpendicular lock cores 5 on bottom and the adjacent opposite side; 6, lock core 5; 6 is prior art.

Advantage and the good effect that the utlity model has are: U font locking bar 1 opening edge is converted into angle, be convenient to pin simultaneously the front fork and the front axle of bicycle, lock cooperates closely with the front fork and the front axle of bicycle, so, when the cracksman destroys lock, thereby no origin of force has guaranteed safety, and Vehicle lock structure is simple, good looking appearance, be difficult for being pried open, easy to use, two lock cores condition each other and guarantee safety.

Fig. 3 is the structural representation of bicycle lock lock body 4.

Among Fig. 1-Fig. 3: 1. locking bar, 2. locking bar inserted link, 3. lock body guard bar, 4. lock body, 5. lock core, 6. lock core, 7. jack, 8. dead bolt, 9. tongue.

The specific embodiment:

For further understanding summary of the invention characteristics of the present utility model and effect following examples for example now, and conjunction with figs. is described in detail as follows, and sees also Fig. 1-Fig. 3.

As shown in Figure 1 and Figure 2: the utility model is made up of locking bar 1, lock body 4, lock core 5,6, locking bar 1 is a circular cross section, integral body surrounds the U font and the both sides of its opening is angled from α (75 °≤α≤150 °), simultaneously, the lock body guard bar 3 of cylindrical locking bar inserted link 2 and semicircle section is made on these both sides respectively, have elongated slot in the middle of them, locking bar inserted link 2 is welded in the openend of U font locking bar 1, and the front end of locking bar inserted link 2 has buckle and may be stuck in the lock core 5 with on the spring controlled dead bolt 8; As shown in Figure 3: lock body 4 is a cuboid; have jack 7 on the one end face with two locking bar inserted link 2 distances and equal diameters; fix two orthogonal conventional lock cores 5 with it on a Dui Ying bottom and the side respectively; 6; have only with key and withdraw from tongue 9 in the side lock core 6 earlier; another key could be disclosed the dead bolt of opening in the lock core 5 of bottom in the lock core 58; at this moment; whole bicycle lock just is opened; the twin-lock core has played the effect of dual fail-safe; simultaneously; locking bar 1 the place ahead of this bicycle lock is because of being converted into certain angle; it can pass bicycle front fork and front axle smoothly; plug lock body 4 along lock

body guard bar

3,3 pairs of lock bodies 4 of lock body guard bar have played protective effect, which direction can not pry open lock body 4 from; can closely cooperate because of bicycle lock and bicycle front fork and front axle again; the little nothing of intermediate space is destroyed origin of force, so safe and reliable, its advantage is: simple in structure; good looking appearance; easy to use; lock is difficult for being pried open; two lock core dual fail-safes; safe and reliable.
