Abstract

The utility model relates to a bicycle steering mechanism lock comprising a lock body, a lock core and a lock bolt; the lock body forms a bent shape with a 90 DEG angle; the front end of a traverse arm is provided with a longitudinal hole which is matched with a vertical rod of a bicycle steering mechanism; the inner side of a hole wall is provided with a stop pin which can be inserted into a prefabrication hole at the corresponding position of the vertical rod of the bicycle steering mechanism; a straight wall of the lock body is provided with the lock core and the lock bolt. A key turns the lock core, which can drive the lock bolt to mover transversely, and a lock bolt head can be inserted in or separated from the prefabrication hole corresponding to a sleeve pipe of the vertical rod to limit or to remove deflection of the steering mechanism and the bicycle in a running direction. The utility model has the advantages of simple and compact structure, novel design, convenient and quick opening or closing, good anti-theft performance and low cost.

Description

The handle-bar lock

The utility model relates to a kind of bicycle lock, and a kind of locking bicycle tap makes front fork and spider form rigidly connected lock during locking.

Bicycle lock is the indispensable annex of bicycle, and its function is, gives locking when car is parked, and reaches theft-proof purpose.Used bicycle lock, it is of a great variety, but its locking form all is the rotation of restriction bicycle front and rear wheel.

The purpose of this utility model is, the lock of a kind of device in the handle-bar vertical rod is provided, and during locking, tap formed with spider be rigidly connected, to limit the deflection of tap and direct of travel.

Its objective is such realization, this lock comprises the lock body and the lock core and the locking bolt that are contained on the lock body straight-arm of 90 ° of crankle shapes, the lock body transverse arm is last, its front end has the vertical hole that matches with the handle-bar vertical rod, the hole wall inboard is equipped with spring and is driven and retractable stop pin, and this tapered end can insert in the pre-manufactured hole of handle-bar vertical rod corresponding position.Transversely movable locking bolt is equipped with in the lower end of lock body straight-arm, and locking bolt bolt head can insert in the pre-manufactured hole of handle-bar vertical rod sleeve pipe corresponding position, during locking, front fork and spider is formed be rigidly connected.Lock core is equipped with in top in lock body straight-arm place, and key is dialled the twist lock core, and the eccentric disk of its rear end can drive the locking bolt side travel, reaches the locking to bicycle.

Handle-bar lock of the present utility model is to take the inflection point of fixing tap to spider, and to limit the deflection of tap and direct of travel, it is novel, and is simple and compact for structure, and lock opens conveniently.Because this lock is to be sleeved in the handle-bar vertical rod, Gu this lock is safe and reliable, and pick-proof is good.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Accompanying drawing is the main cutaway view according to the handle-bar lock that the utility model proposes.

Describe details and the condition of service of locking according to the handle-bar that the utility model proposes in detail below in conjunction with accompanying drawing.

This lock comprises lock body [2], lock core [7], the locking bolt [3] that is 90 ° of crankle shapes, the front end of lock body transverse arm has a longitudinal hole, this hole and handle-bar vertical rod match, there is a blind hole its hole wall inboard, built-in spring [10] and stop pin [11], the pre-manufactured hole of pin a diameter and handle-bar vertical rod corresponding position matches, and for combining of reinforcing lock body and leading vertical rod, is provided with holding screw [12] in the transverse arm outer end.There is horizontal stepped hole the lower end of lock body straight-arm, and there is one section axial channel in the macropore aperture, and T shape cylindrical shape folding locking bolt is contained in the stepped hole, lateral pin [5] is equipped with at its place, rear portion, has before it to be sleeved on the outer stage clip [4] of locking bolt, at the big outer end of hole of stepped hole, cover plate [6] is housed, and there is the hole vertical with locking bolt at the lock body place above the locking bolt leading portion, in be installed pin [1], stage clip [9], at this lock locking states, locking bolt and bayonet lock on the locking bolt of synapsis, have the draw-in groove that matches with the bayonet lock head mutually.The top of lock body straight-arm is parallel with locking bolt is equipped with lock core, and the eccentric disk of lock core rear end [8] touches mutually with the inboard of bayonet lock, and the phase synapsis of bayonet lock has draw-in groove, and eccentric disk and this draw-in groove match, and when key was dialled the twist lock core, eccentric disk just drove the bayonet lock rise and fall.

The installation of this lock is: when bicycle is assembled, this lock transverse arm is sleeved in the handle-bar vertical rod, allows stop pin insert in the preset holes in the leading vertical rod, tighten holding screw and get final product.Its use is as follows, by advancing locking bolt, makes in the pre-manufactured hole on the bolt head insertion handle-bar vertical rod sleeve pipe, and bayonet lock is under the promotion of stage clip at this moment, and the bayonet lock head is dropped in the draw-in groove of locking bolt corresponding position, front fork and spider is formed be rigidly connected, and realizes the lock car; When unblanking, key is dialled the twist lock core, and eccentric disk drives bayonet lock and rises, and the pin head detaches the draw-in groove on the locking bolt, and at this moment, locking bolt is return under the effect of pressing bullet, and withdraws from the pre-manufactured hole on the handle-bar vertical rod sleeve pipe, thereby removes the constraint of front fork and spider.
