Abstract

The utility model discloses an anti-theft device for deflected locking of a front fork of a bicycle, which comprises a lock casing, a lock seat, a sleeve barrel of a front fork, a handle of front fork and a pin. The lock seat is composed of a lock seat ring and a lock seat plate; the lock seat ring is positioned on the lower end of the sleeve barrel of a front fork and is sheathed on the handle of front fork; the lock seat plate is upward fixed on the right side of the sleeve barrel of a front fork; a lock body is fixed on the lock seat plate by screws; the pin is arranged in a pin body; the wall of the sleeve barrel of a front fork and the handle of the front fork are respectively provided with a corresponding pin hole. The utility model has the advantages of high anti-theft performance, small size, simple structure, low cost, convenient operation, etc.

Description

The anti-joyride device of bicycle front fork deflection locking

The utility model relates to the anti-joyride device of a kind of bicycle front fork deflection locking.

Bicycle theft-prevention always is to pin wheel with handcuffs shape lock or cable-type padlock, is mostly fixedly trailing wheel, and its shortcoming is that lock body is bigger, and safety is not high, opens the inconvenience of locking.

The purpose of this utility model is to provide a kind of very strong anti-theft capability that has for addressing the above problem, and opens the anti-joyride device of the bicycle front fork deflection locking of locking easy to operate, that the bodily form is little, simple in structure.

The purpose of this utility model can realize by following measure: lock body is fixed on the lock, lock is connected before bicycle front fork sleeve right side and its lower end on the fork handle, all have corresponding pin-and-hole on front fork sleeve and the preceding fork handle, pass the locking of front fork deflection with the pin that holds lock body, bicycle can not be moved ahead realize.

The utility model compared with prior art has the following advantages: because this apparatus structure is tight, can not dismantle after the locking, anti-theft capability has very big reinforcement; The APF active position forward rising makes easy to operate, and the bodily form is little, simple in structure, cost is low.

Fig. 4 is the schematic side view of the utility model lock plate

Below in conjunction with accompanying drawing the utility model is further described:

Look this device as Fig. 1,2,3,4, it includes lock body (3), lock (2,7), front fork sleeve (8), preceding fork handle (9), pin (5).Lock (2,7) is made up of lock circle (2) and lock plate (7), lock circle (2) is in front fork sleeve (8) lower end, be enclosed within on the preceding fork handle (9), lock plate (7) upwards, be fixed on front fork sleeve (8) right side, lock body (3) is fixed on the lock plate (7) with screw (4), pin (5) is located in the lock body (3), on front fork sleeve wall (8) and preceding fork handle (9), all have corresponding pinhole (10,11) promptly before fork handle (9) the place ahead or 1 pin-and-hole in rear (11) front fork sleeve (8), 1 pin-and-hole in right side (10).

Pin (5) is in the above-mentioned pin-and-hole (10,11) the locking of preceding fork handle (9) deflection as shown in Figure 1; Fork handle pinhole (11) before pin (5) withdraws from as shown in Figure 2 can freely rotate preceding fork handle (9); Lock circle (2) interconnects with lock plate (7) as shown in Figure 3, angle between two planes of bonded assembly is 90 °, inboard, two planes of bonded assembly is provided with the size of interior radius of circle of reinforced rib (1), lock circle (2) because of the thickness of different bicycle front fork handles (9) is different, is slightly larger than preceding fork handle (9) cross section radius of circle and loosening getting final product.Size at front fork sleeve (8) right side pinhole (10) is identical with the pinhole (6) of lock plate (7) as shown in Figure 1, 2, pinhole (11) on the preceding fork handle (9) is bigger slightly than the pinhole (6) of lock plate (7), so that pin (5) inserts easily, its size of pinhole (6) is slightly larger than the cross-sectional plane of pin (5).With handlebar left or turn right 90 ° and stir pin (5) with key, pin (5) just passes three pinholes (6,10,11) with the locking of bicycle deflection when stopping, and taking out key can be effectively antitheft.

This device is fit to bicycle, manual tricycle uses.

Claims
