Description

Collapsible anti-theft bicycle handlebar

It is folding downwards that the utility model relates to a kind of handlebar two ends, particularly can prevent a kind of device that bicycle is stolen.

The handlebar that bicycle uses is processed by tubing, only is used for go-cart or use by bike the time for people.But this handlebar has such problem, when needs are parked, and handlebar a lot of spatial area that just accounts for, and also also inconvenient when inlet/outlet, so usually can damage some things unintentionally.Therefore, people always outside bicycle parking, thereby cause losing of bicycle.

For addressing this problem, common way is the bicycle use anti-theft column lock under lock and key, just can prevent stolen effectively.But, be difficult to play theft-proof effect for general anti-theft column lock.Because after general anti-theft column lock is prized by the people, still can push away away bicycle or ride away.

The purpose of this utility model provides a kind of device of improved collapsible anti-theft bicycle handlebar, and it can prevent effectively that bicycle is stolen.

The purpose of this utility model divides such two steps to realize: (one) is therefrom separated existing handlebar, be processed into open circuited two square then, and former fixedly handlebar place changed into the square groove material that opening makes progress, the bottom at this square groove material two is sliced off with the handlebar equal diameters one section, on front and rear wall, hole then, it is coupled together the handlebar that separates with axle, so that the handlebar two ends are folding downwards, simultaneously, below the square groove material, adorn one " ∩ " shape anti-theft column lock, and make a call to two latch arm hole.When opening this lock, extract locking bar out, the handlebar two ends are folding downwards, and then lock this lock, and the handlebar two ends can't be lifted, thereby guarantee that stealer can't be by bike.(2) set up a telescoping catheter in the blank pipe at handlebar two ends, this conduit respectively has button control (the button principle on this button and the umbrella is identical), and at two outer end internal fixation, one cylinder-type lock of this conduit, i.e. catheter lock.After the handlebar two ends are put down, press button, conduit jumps out voluntarily, and lock pins front-wheel thus then, thereby guarantees that handlebar and front-wheel are integrated, and make stealer can't grasp the direction go-cart.

The utility model disconnects former handlebar because only need, be processed into open circuited two square, it can be combined in the square groove material, and adorn one " ∩ " shape anti-theft column lock in the bottom of square groove material, simultaneously, set up a catheter lock in the blank pipe at former handlebar two ends, this lock has button control flexible, so simple in structure, realize easily antitheft with reduce the requirement of floor area.

This calamity is provided by following embodiment and accompanying drawing thereof with later-model concrete structure.

Fig. 1 is the section-drawing according to the collapsible anti-theft bicycle handle bar device that the utility model proposes.

Describe details and service condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

This device comprises a handlebar main body (1), the centre of main body set up one can folding groove material (2), under it, adorn one " ∩ " shape anti-theft column lock (3), and in the blank pipe at handlebar two ends, set up telescoping catheter lock (4), this conduit has button control (5).

During parking, open " ∩ " shape anti-theft column lock (3) earlier, extract " ∩ " shape bar out, the handlebar two ends are folding downwards, press button (5) catheter lock (4) then, stretch out automatically, pin front vehicle wheel with this lock, but just end operation process gets final product to reverse operation when riding.
