Abstract

The utility model discloses a bicycle of lock is put to in -band, include the V -arrangement frame that is linked to be by seat pipe and enhancement pipe chute, the preceding fork arm that handlebar hand, lower extreme connection front wheel shaft are being connected to the upper end, its characterized in that are established to breeches pipe before the pipe chute front end intercommunication, the intraductal cover of this front fork: the pipe chute front end embeds the spring bolt orientation of a latch fitting, this latch fitting preceding breeches pipe, on the preceding fork arm with the crossing position of pipe chute sets up a matching and inserts the lockhole of spring bolt, this handlebar hand -motion preceding fork arm and front wheel turn left 45 when spending the lockhole is aimed at the spring bolt. Compared with the prior art, the utility model discloses a bicycle of lock is put to in -band embeds there is head lock, is difficult for suffering maliciously damage, and the front wheel is fixed 45 degrees messenger's bicycles and can't be moved ahead the security height after locking.

Description

A kind of bicycle of band built-in lock

Technical field

This utility model relates to a kind of bicycle, the bicycle of a kind of band built-in lock.

Background technology

Bicycle is a kind of light trip instrument, and its unique convenience makes it be liked by numerous people, but Being that the situation that bicycle is stolen is of common occurrence, bicycle is the most antitheft becomes headachy problem always, existing Theft-proof lock for bicycle is typically all screwed on the vehicle frame sat below saddle, or uses additional lock such as ferrum Chain lock, cable lock, D letter lock etc. are fixed by lock through the steel ring of wheel before and after bicycle.These common cars Lock, generally all as bicycle adnexa onboard, not only affects the good looking appearance of bicycle, and is easily prized Opening or cut off, safety does not ensures.

Utility model content

The purpose of this utility model is to overcome shortcoming of the prior art with not enough, it is provided that a kind of safety is high The bicycle of band built-in lock.

This utility model is achieved through the following technical solutions: the bicycle of a kind of band built-in lock, including by justifying The V-arrangement vehicle frame that tubular seat pipe and square reinforcement inclined tube are linked to be, described inclined tube front end connection front fork tube, this front fork In pipe, sheathed upper end is connected to handlebar, the front fork stem of lower end connection front-wheel wheel shaft, and described seat pipe upper end is socketed The seatpost of connection cushion, it is characterised in that: the built-in latch fitting in described inclined tube front end, the dead bolt of this latch fitting towards Described front fork tube, the position that described front fork stem intersects with described inclined tube arranges a coupling and inserts described dead bolt It is cylindrical that lockhole, described dead bolt and described lockhole are.Before this handlebar drives described front fork stem and bicycle During wheel left-hand rotation 45 degree, described lockhole is directed at described dead bolt.

Compared to prior art, the bicycle of band built-in lock of the present utility model is built-in with head lock, does not subject to dislike Meaning damage, after locking, the fixing left-hand rotation of front-wheel 45 degree makes bicycle to move ahead, and safety is high.

Further, square described inclined tube front end side wall offering opening, the key hole of described latch fitting is from this Opening exposes, and inserts for supporting key.

In order to enable apparent understanding this utility model, illustrate to illustrate of the present utility model below with reference to accompanying drawing Preferably embodiment.

Accompanying drawing explanation

Fig. 1 is the structural representation during bicycle non-locking of this utility model band built-in lock.

Fig. 2 is the structural representation during bicycle locking of this utility model band built-in lock.

Fig. 3 is the perspective structure schematic diagram of front fork tube in Fig. 1.

Fig. 4 is the perspective structure schematic diagram of front fork tube in Fig. 2.

Detailed description of the invention

It it is the structure during bicycle non-locking of this utility model band built-in lock please refer to Fig. 1 to Fig. 4, Fig. 1 Schematic diagram, Fig. 2 is the structural representation during bicycle locking of this utility model band built-in lock, and Fig. 3 is Fig. 1 The perspective structure schematic diagram of middle front fork tube, Fig. 4 is the perspective structure schematic diagram of front fork tube in Fig. 2.In this band Put the V-arrangement vehicle frame that the bicycle of lock includes being linked to be, described seat by cylindrical shape seat pipe 10 and square reinforcement inclined tube 20 The seatpost 11 of pipe 10 upper end socket connection cushion 12.Described inclined tube 20 front end connection front fork tube 21, before this In breeches pipe 21, sheathed upper end is connected to handlebar 24, the front fork stem 22 of lower end connection front-wheel wheel shaft, this inclined tube The built-in latch fitting 30 in 20 front ends.

The dead bolt 31 of this latch fitting 30 is towards described front fork tube 21, with described inclined tube 20 on described front fork stem 22 The position intersected arranges a coupling and inserts the lockhole 23 of described dead bolt 31, described dead bolt 31 and described lockhole 23 It is cylindrical for being.Described lock when this handlebar 24 drives described front fork stem 22 and bicycle front-wheel left-hand rotation 45 degree Hole 23 is directed at described dead bolt 31.

Described inclined tube 20 is square, and its front end side wall offers opening, the key hole 32 of described latch fitting 30 Expose from this opening, insert for supporting key.

When needing to lock to bicycle, described lockhole 23 is made to be directed at described dead bolt 31 bicycle head left-hand rotation 45 degree, The key that turn is supporting, the lockhole 23 that this dead bolt 31 stretches out and inserts on front fork stem 22, now single head lock The state of dead fixing left-hand rotation 45, it is impossible to promote bicycle again.

This utility model is not limited to above-mentioned embodiment, if to various changes of the present utility model or change Shape is without departing from spirit and scope of the present utility model, if these are changed and deformation belongs to power of the present utility model Profit requires and within the scope of equivalent technologies, then this utility model is also intended to comprise these changes and deformation.
