Abstract
The utility model relates to an anti-prizing bicycle (or a trishaw). The utility model comprises a tripod, wheels, a saddle, pedals and a chain transmission mechanism. The utility model is characterized in that a reverse movement lock with double tongue is installed in a front lever downwards inclined of the tripod, when the reverse movement lock with double tongue is locked, an upper lock tongue and a lower lock tongue of the reverse movement lock with double tongue can be inserted into an upper tongue insertion hole of a front joint rivet and lower tongue insertion holes of pedal centre shafts; when the utility model is locked, a front wheel and a handlebar are locked, the front wheel can form an angle ranging from 80 DEG to 90 DEG with the tripod; at the same time, pedal centre shafts are locked, pedal arms can be vertical with the ground, and thus, a bicycle is unable to push in a straight line and only can be circularly pushed in situ.
Description
The utility model relates to bicycle, trishaw, particularly a kind of bicycle and theft-proof lock integrated antitheft sled bicycle.
Usually all bicycle lock of adapted or chain lock are used for the antitheft of car to existing bicycle.This lock is easily pried open, is destroyed, and anti-theft effect is undesirable.
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, provides a kind of anti-theft column lock and bicycle incorporate anti-prize and steal bicycle or three-wheel vehicle.
The antitheft sled bicycle of the utility model comprises: spider, trailing wheel, vehicle seat, foot-operated, chain drive, front-wheel and handlebar by pincers axle mounting before the handlebar; It is characterized in that: in the slash two tongue counter motion locks are installed down before the spider, have the tongue hole on the preceding pincers axle, pin is stepped on and is had down the tongue hole on the axis, the following tongue hole that the last tongue hole of pincers axle and pin were stepped on axis before its upper and lower dead bolt can insert when two tongue counter motions were locked.When locking, locking front-wheel and handlebar make front-wheel and triangle put up 80~an angle of 90 degrees, lock pin simultaneously and step on axis and make and ride arm and become vertical with ground, and the bicycle implementation that can't be in line like this can only be carried out at the pirouette circle.
Advantage of the present utility model is as follows:
Anti-theft column lock is hidden in bicycle main body spider, fuses with car load, makes it and can't prize and steal, and can only damage.
Anti-theft column lock is two tongue counter motion lock constructions, and when locking, locking front-wheel and handlebar make front-wheel and triangle put up 80~an angle of 90 degrees, locks pin simultaneously and steps on axis and make and ride arm and become vertical with ground.As long as a lock is locked, bicycle implementations that can't be in line can only will be kept straight on to have only front-wheel is lifted from ground in the implementation of pirouette circle like this, and trailing wheel could be kept straight on.After foot-operated arm is locked, lose the condition of leaving fast by bike.The car stealer can only shoulder bicycle and walk, or just can transport bicycle with other method.Promptly be that bicycle is transported,, can not prize that can only cut off spider, bicycle has become to ruin product like this, can not dispose of stolen goods because bicycle and lock are integrated.Even if after the spider cut-out, take lock away, allow the people find out that at a glance this car is of unknown origin like this from the new spider that welded.
Description of drawings of the present utility model is as follows:
Fig. 1 is the utility model integral structure figure;
Fig. 2 is Fig. 1 anti-theft column lock part enlarged drawing;
Fig. 3 is the block diagram of its anti-theft column lock;
Fig. 4 is the three-dimensional exploded view of its anti-theft column lock.
As shown in Figure 1, the utility model is the innovative product of existing bicycle, all same prior aries such as its main portion front-wheel, trailing wheel, vehicle seat, foot-operated, chain drive, handlebar, spider.In the slash two tongue counter motion locks are installed down before its spider, its upper and lower dead bolt can insert the last tongue hole of preceding pincers axle and the following tongue hole that pin is stepped on axis, two-way locking bicycle when two tongue counter motions were locked.
As shown in Figure 2, anti-theft column lock is hidden before spider to descend in the slash.Its foot-operated axis 9 is different with common axis, the middle overstriking of axis, and pin is stepped on and is had down the tongue hole on the axis 9,8 one-tenth 138 degree of the axis in this time tongue hole and downward foot-operated arm angle.Pincers axle 12 also has change before the handlebar, also has one on the preceding pincers axle 12 and goes up the tongue hole, and the axis in this hole and triangle are put up 0~10 degree angle, make front-wheel and triangle put up 80~an angle of 90 degrees after the locking.These two holes are two tongue holes of anti-theft column lock, are used for locking preceding pincers axle of foot-operated arm and handlebar and front-wheel.
That the reinforcement of tongue via hole with lock is set respectively is fast 10,11 at slash 13 two down before the spider, so that strengthen the intensity of car, lock, avoids car to be destroyed by force by the robber.After such improvement, when anti-theft column lock was opened, dead bolt 5,6 retreated to simultaneously with to strengthen fast 10,11 end faces concordant. Dead bolt 5,6 clamps the last tongue hole of axle 12 and the following tongue hole of foot-operated axis 9 before inserting handlebar respectively during locking.Blocked like this bicycle (or three-wheel vehicle) just promptly can not be trampled, and can not carry out by straight line again, has played extraordinary theft protection effect.
The structure of anti-theft column lock is shown in Fig. 3,4, this pair tongue counter motion lock comprises: lock body 1, be installed on the lock shaft 2 of locking body 1, goat's horn spare 3, jump ring 4, upper lock tongue 5, following dead bolt 6 and flute profile locking closure 7, flute profile locking closure 7 is anchored on the lock body 1, goat's horn spare 3 is installed in the groove of lock shaft 2 ends, by the jump ring 4 that is installed in the draw-in groove both chuckings are integral, insert in the mountain peak shape track groove of upper and lower dead bolt the upper end of goat's horn spare 3, makes lock body, the rotation of goat's horn spare drive upper and lower dead bolt and slide by key.
This lock principal feature is: key is by being installed in the lock shaft 2 of lock body 1, and goat's horn spare 3 drives two dead bolts 5,6, reversing sense motion locking or unlatching.To reach the function that a lock can lock two fixed points, this lock removes and is used on bicycle, the three-wheel vehicle, also has purposes very widely.
