Description
The utility model belongs to the bicycle theft-prevention technical field, is a kind of collapsible lock control anti-theft bicycle tap.
Bicycle is one of people's main tool of riding instead of walk.Along with growth in the living standard, increasing people is tending towards buying middle and high shelves car, as racing car, mountain bike, for antitheft, this class car is taked the method that locks simultaneously usually on front and rear wheel, but because outside the lock that uses is exposed to, very easily cut off with the reinforcing bar pincers, lose antitheft effect by the burglar.Bicycle is stolen, brings many inconvenience and worried to the user on the one hand, also makes the stepping back of some buyer's news on the other hand, brings obstacle for the consumption of middle and high shelves car.
The purpose of this utility model is intended to overcome the deficiency of prior art, provides a kind of and controls its folding of bicycle tap by hidden lock control system, makes it when parking, even the key thief has destroyed rear wheel lock, also can't use this car, thereby play antitheft effect.
The purpose of this utility model reaches like this: on the upright basis of the handlebar of existing racing car, mountain bike and handlebar, at handlebar the upright front end U-shaped cross section fixed cover that is connected, handlebar is divided into two sections, coupling end is connected on the adapter shaft that is connected in the fixed cover of U-shaped cross section by the shaft hole sleeve on it, and can rotate around adapter shaft, realize folding or opening.In order to control the running condition of handlebar, handlebar connects and has the groove that is complementary with the dead bolt gabarit on the end, to cooperate with dead bolt.Built-in lock is installed on handlebar in upright, and its dead bolt can be interior with Lock of handlebar or disengagement by the groove of the embedding of the dead bolt hole on the fixed cover of U-shaped cross section handlebar coupling end.
Concrete structure of the present utility model is provided by the following drawings and embodiment.
Fig. 1 is the utility model contour structures scheme drawing;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the A-A cutaway view of the utility model handlebar fold latch timing diagram 1;
Fig. 4 is the B-B cutaway view of Fig. 1;
Fig. 5 is the C-C cutaway view of Fig. 1;
Fig. 6 is another structural representation of the collapsible lock control anti-theft bicycle tap that proposes according to the utility model, is that characteristics are on Fig. 1～architecture basics shown in Figure 5, increases by four gears in meshs on U-shaped cross section fixed cover and handlebar coupling end.
Present embodiment structure such as Fig. 1～shown in Figure 5 comprise that handlebar 1, handlebar are upright 4, U-shaped cross section fixed cover 5, adapter shaft 6, built-in lock 7.
U-shaped cross section fixed cover 5 is connected in handlebar upright 4 front ends, and opening is oblique below before car, like this, also oblique below before car after can making on the one hand connection handlebar 1 wherein folding, even key the thief go smoothly, can not ride away, can reduce drench with rain corrosion and dust fall pollution on the other hand relatively.Symmetry has two pairs of axis holes on 5 liang of folder faces of U-shaped cross section fixed cover, and adapter shaft 6 passes wherein and is fixed in.
About handlebar 1 is divided into from the centre two sections, it disconnects partly is coupling end 2.This coupling end 2 is circular rotor, rotor 2 middle parts have axis hole, and left and right handlebar 1 is socketed on respectively on two adapter shafts 6 that are connected in the U-shaped cross section fixed cover 5 by coupling end rotor 2 axis holes, and can rotate around adapter shaft 6 separately, to realize that handlebar is folding or to open.For fixing these two kinds of running conditions of handlebar, two circular rotors 2 ' on, have two pairs of grooves 3 that are complementary with built-in lock dead bolt 8 gabarits symmetrically, and the lockhole that constitutes of per two groove opposite 3 could with the gabarit coupling of dead bolt 8 with handlebar 1 locking.Spacing＞50 of each circular rotor 2 ' last two groove 3 ° and≤90 °.During use, handlebar 1 opens, and makes dead bolt 8 spring into locking in the two relative grooves 3.When parking, regain dead bolt 8, Foldable handlebar 1 makes dead bolt 8 spring into another to locking in the groove 3 again.
Built-in lock 7 is installed on handlebar standing in 4, and its dead bolt 8 can be under key control, and the groove 3 that embeds handlebar coupling end 2 by the dead bolt hole on the U-shaped cross section fixed cover 5 is interior with handlebar 1 locking or disengagement.Dead bolt 8 be shaped as dumbbell shaped or class dumbbell shaped.What present embodiment adopted is the class dumbbell shaped.Built-in lock dead bolt 8 mode of motion both can have been selected the mode of motion of common door built-in lock dead bolt for use, also can select the mode of motion of general drawer built-in lock dead bolt for use, but select for use the former more convenient.
Present embodiment also comprises handlebar 1, handlebar upright 4, U-shaped cross section fixed cover 5, adapter shaft 6 and built-in lock 7, its structure such as Fig. 1～shown in Figure 5, and wherein the shape of each parts, mutual annexation and function are as described in the embodiment 1, slightly.
Different is to open, fold for the energy one hand carries out handlebar 1, especially open operation, respectively be fixed with a gear 9, two gears 9 on the handlebar coupling end 2 in U-shaped cross section fixed cover 5 and with being connected in U-shaped cross section fixed cover 5 interior intermeshing another gear 10 meshed respectively, see Fig. 6.During operation,, just can the handlebar 1 of another side be rotated synchronously by the transmission of engaging gear 9,10 as long as pull handlebar 1 on one side.Both saved trouble like this, and avoided the right-hand man to operate simultaneously when inharmonious again, dead bolt 8 can not spring into the problem of groove 3 smoothly.
Because the utility model handlebar is in folded state when parking and again by built-in lock locking, the car stealer can't be destroyed at the scene with conventional approach, if destroyed at this moment rear wheel lock, also can not ride because of handlebar is folding.Even built-in lock is destroyed, but can't fixes and can not use, thereby the utility model theftproof performance is good because of handlebar, and simple in structure, make handling ease, easy to use, the folding back of tap takes up space little, is convenient to leave with.
