Abstract

The utility model belongs to an anti-theft device, particularly an anti-theft stand lock for a bicycle. Two long edges of a rectangle frame are respectively fixed with a side stand; the other end of the side stand is connected with a stand rotating disk. A rear shaft roller of the bicycle passes through a middle hole of the stand rotating disk; the stand rotating disk is tightly fixed outside a shaft fender of a rear shaft of the bicycle by a stand rotating disk; the two long edges of the rectangle stand frame are respectively fixedly provided with a folded plate having a hinge; a lock body is arranged on the folded plate having the hinge; a lock-tongue slot for accommodating a lock tongue is arranged on the folded plate. Due to the fact that the folded plate for installing the lock body passes through the gap between two vehicle bars to be connected with the folded plates into integration via a lock, when the two folded plates are connected via the lock, the lock tongue enters a lock slot, and the lock tongue is not exposed so that a thief does not easily clip the lock tongue by using a pair of pliers, and in addition, the plate body of the folded plate is tightly embraced with wheels, therefore, the plate body and the wheels are not easy to prize to lead to damage. After an anti-skid wheel is arranged, due to the fact that the bicycle is supported by three points, the functions of safety and stability can be performed.

Description

Bicycle theft-prevention support lock

Technical field

The utility model belongs to the anti-joyride device field, particularly the theft-prevention supporter of bicycle lock.

Background technology

Bicycle is at present at home still as the main vehicle, but the stolen phenomenon of the disgustful bicycle of people is often occurred, and traces it to its cause, and the design defect of bicycle lock is one of stolen reason of bicycle.

The bicycle lock of selling on market at present has various, as rod lock, chain lock, cable-type padlock, rim lock etc., but these locks are overstriking dead bolt on the design basis of original lock just, the designer's of lock antitheft thought does not break away from the design of original lock, outside dead bolt still is exposed to, and such design is still cut off with pliers or is pried open by the thief easily, steals bicycle.

Make a general survey of existing bicycle, when blowing or colliding with the people, because bicycle and ground contact point are one or two (putting down support when depositing) point, be easy to be blown down or knock over by wind or people, especially in snowy day, more the cyclist dare not be set out on a journey by bike, traces it to its cause owing to the road is sliding, be because existing bicycle also do not have one can safe and effective assurance bicycle parking or the device of enforcement.

Summary of the invention

One of the purpose of this utility model is the defective that overcomes existing bicycle lock, and a kind of bicycle theft-prevention support locking device that can prevent effectively that bicycle is stolen is provided, to solve the people that produce owing to bicycle the is stolen complaint to social security.

Another purpose of the present utility model provides a kind of anti-skid device of bicycle, does not have the device of safe and effective assurance bicycle parking or enforcement in wind or snow sky to overcome present bicycle.

The purpose of this utility model is achieved in that a rectangle support frame 1, is fixed with side stand 2 respectively on two long limits of rectangle frame, and the other end of side stand 2 is connected with a support rolling disc 14; Described support rolling disc 14 is the device of a similar bearing, bicycle rear axle roller 18 passes the middle hole of support rolling disc 14, with a clamp nut 20 support rolling disc 14 is fastened on the outside of the axle shelves 19 of bicycle rear axle 17 then, thereby the rectangle support frame 1 that connects support 2 can be rotated around bicycle rear axle; On two long limits of rectangle support frame 1, fixedly mount flap 4 and the flap 4 ' that has hinge 7 respectively, on described flap 4, lock body 22 is installed, have the lock tongue slot 16 of ccontaining dead bolt 3 on the flap 4 '.

Described flap 4 is made up of two or three blocks of flaps, and the width that the flap 4 of lock body 22 parts wherein is installed is as the criterion with the space that can pass between two spoke, and the flap of lock body 22 parts will cover wheel and flap 4 ' and be linked to be by lock and be one.For the ease of adjusting the distance between flap 4 and the flap 4 ', flap near wheel and installation lock body 22 parts further can be divided into two blocks of flaps, these two blocks of flaps can be formed by connecting by flexible radius stay 8, just can adjust distance between flap 4 and the flap 4 ' by flexible radius stay 8 like this, avoid when expanding with heat and contract with cold, causing dead bolt can not enter in the locked groove owing to flap institute materials used; Described flexible radius stay is the stock that an end makes big hat, to install 2 for good.

Described side stand 2 is installed 2 for good for the long limit of every rectangle support frame 1.

The fixedly locking bar 6 of two grooves with lock further is installed on the frame pipe of the rectangle support frame 1 at described flap 4 places, and its length can be decided as required.

Reflective taillight 10 further is installed on the described rectangle support frame 1.

On the described rectangle support frame 1 bicycle number plate 9 is installed further.

On the described rectangle support frame 1 fixed card 11 that resets is installed further.

On the described rectangle support frame 1 anti sliding wheel 13 is installed further.

On the described rectangle support frame 1 support movable handle 15 is installed further.

Described anti sliding wheel 13 is mounted in an end of a wheel carrier 21, and the other end of wheel carrier 21 inserts in the frame pipe of forming rectangle support frame 1, by check screw 12 fixing (check screw 12 passes the frame pipe and props up wheel carrier 21).

The utility model in use, the fixed card that at first will reset is opened, hand-holdable support movable handle puts down the rectangle support frame, with key lock is opened, dead bolt shifts out from the locked groove of fixing locking bar, lock body is moved down, and the flap that the opposite has lock tongue slot is stretched in the space that lock body passes between two spoke, with key lock is locked, the flap 4 that has hinge is linked into an integrated entity with plate plate 4 '; When by bike, open lock, lock body is moved up, the space of flap 4 between two spoke that has hinge withdrawed from, lock is locked, its dead bolt is locked the locked groove on the fixing locking bar, and the flap 4 that has hinge is fixed, the car crash that causes with the swing of avoiding by bike the time owing to flap 4; Mention the rectangle support frame, the fixed card that will reset is fastened on the rear deck seat and gets final product.

The utility model is owing to install the flap 4 of lock body 22 parts and pass space between two spoke and flap body 4 ' and be linked to be by lock and be one, so when bifoldable plate is joined together by lock, dead bolt is to enter into locked groove, dead bolt does not expose, the thief is not easy to cut off dead bolt with pliers like this, and the plate body of flap is tightly embraced together with wheel and also is difficult for being prized bad by the thief.When parking bicycle, because the rectangle support frame has strengthened the bearing surface of car, so when blowing, can prevent that car is blown over by the wind.

The utility model is after installing anti sliding wheel additional, owing to being the three point support bicycle, so can play the effect of safety and firmness.Especially by bike the time, put down the purpose that anti sliding wheel just can reach the safety enforcement in snow sky.If license plate is installed in the obvious place on the rectangle support frame, can allow the people come into plain view, improve the significant degree of license plate; And install reflective taillight additional, can point out the automobilist to dodge at night.
