Abstract

The utility model discloses a wheel lock for bicycles. The utility model is composed of a copying lock body (1), and a U-shaped copying lock fork (2). The shape of the inner side face of the copying lock body (1) is inosculated with the shape of the outer porch of a bicycle wheel rim; the shape of the inner side face of the U-shaped copying lock fork (2) is inosculated with outline of the outer tyre of a bicycle wheel. The two parts are matched, and the corresponding bicycle wheel is locked from the direction of a cross section. The special structure and material of the utility model can effectively prevented the utility model form being picked and cut, and the theft-proof goal is achieved. The utility model has the advantages of simple structure, high safety, and convenient use.

Description

The cycle wheel lock

The utility model relates to a kind of bicycle lock device, especially a kind of cycle wheel lock that matches with wheel cross section outer shape.

At present people are used to the lock that prevents that bicycle is stolen, owing to structural reason, after it is installed on the bicycle, or there is the stressed fulcrum be utilized and easily pried open, or have enough spaces allow to destroy and cut move place, make joyriding succeed, thereby fail the effectively effect of performance lock.About having pick-proof, the anti-cycle wheel lock of cutting function really, do not see the report of success so far.

The purpose of this utility model is that a kind of anti-cycle wheel lock of cutting function of pick-proof that has is provided for the weak point that overcomes existing bicycle lock.

In order to achieve the above object, the solution that the utility model adopts is: adopt a kind of profiling that makes cycle wheel lock and cycle wheel cross section outer shape match to establish the skill scheme, the cycle wheel locking device is made up of lock body (1) and lock fork (2), lock core (3), dead bolt (4), interlock dead man (5) are housed in the lock body (1), and lock body (1) both sides, lower end have and the two fork corresponding sockets (6) of locking fork (2).Design feature of the present utility model is that lock body (1) is ∪ shape profiling lock fork for profiling lock body, lock fork (2); Match along shape in the medial surface shape of profiling lock body (1) and the bicycle rim, and adopt the metal manufacturing, preferably adopt steel-casting; The medial surface shape of ∪ shape profiling lock fork (2) and the outline of cycle wheel cover tire match, and adopt the alloy steel manufacturing.The shape of cross section of ∪ shape profiling lock fork (2) is preferably semicircle, and its ∪ shape two ends can fit in one with profiling lock body (1) and with wheel locking.

Because the utility model adopts contoured design, make the cycle wheel lock cooperate closely with cycle wheel, thereby the fulcrum that makes picking lock is selected on the wheel or is selected on the ∪ shape profiling lock fork (2), and its result must be to be cost to destroy wheel, and may not succeed; Also cut no activity space, and ∪ shape profiling lock fork (2) adopts special shape and material again, can effectively stop the car stealer to cut off lock with scissors because above-mentioned design order destroys.The utility model is simple in structure, safe and reliable, easy to use, be easy to promote.

Fig. 1 is the structural representation of the utility model cycle wheel lock;

Fig. 2 is the ∪ shape profiling lock fork schematic diagram of the utility model cycle wheel lock;

Fig. 3 is that the ∪ shape profiling lock of the utility model cycle wheel lock is pitched along A--A direction sectional view.

Below in conjunction with accompanying drawing and most preferred embodiment the utility model is described in further detail:

Fig. 1 is the structural representation of the utility model cycle wheel lock; As shown in Figure 1, the cycle wheel locking device is made up of lock body (1) and lock fork (2), and lock core (3), dead bolt (4), interlock dead man (5) are housed in the lock body (1), and lock body (1) both sides, lower end have and the two fork corresponding sockets (6) of locking fork (2).Lock body (1) is the profiling lock body, matches along shape in its medial surface shape and the bicycle rim, and adopts the metal manufacturing, preferably adopts steel-casting.Lock fork (2) is a ∪ shape profiling lock fork (as shown in Figure 2), and the outline of its medial surface shape and cycle wheel cover tire matches; The two ends medial surface of ∪ shape profiling lock fork (2) respectively has breach (7), and its position is corresponding with two dead bolts (4) in the lock body (1); ∪ shape profiling lock fork (2) adopts the alloy steel manufacturing, and its mechanical tensile strength is 110～160kg/mm ², mechanical hardness is HB229～232; The shape of cross section of ∪ shape profiling lock fork (2) preferred semicircle (as shown in Figure 3), its sectional area scope is at 50～100mm ²Between, 80mm preferably ²When profiling lock body (1) is pitched (2) when cooperating (as shown in Figure 1) with ∪ shape profiling lock, owing to adopt contoured design, therefore, the edge matches in the medial surface of profiling lock body (1) and the bicycle rim, the interior edge of ∪ shape profiling lock fork (2) matches with the outline of cycle wheel cover tire, at this moment, a pair of dead bolt (4) of profiling lock body (1) blocks ∪ shape profiling lock fork (2) two ends breach (7) under the effect of interlock dead man (5), thereby finishes locking.When opening the lock with the key, the interlock dead man (5) that lock core (3) rotated and drove its lower end make contract in the dead bolt (4) break away from ∪ shape profiling lock fork (2) two ends breach (7) thus finish and unblank.

Lock core (3), dead bolt (4), interlock dead man (5) are all known technology, are omitted at this.

When the utility model was implemented, lock body (1) also can adopt other stiff materials manufacturings except that the above cast steel.∪ shape profiling lock fork (2) also can be selected other shapes except that the above preferred semicircle.
