Description

A kind of can the bicycle of internal lock headstock

Technical field

This utility model relates to a kind of bicycle, a kind of can the bicycle of internal lock headstock.

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 Can the bicycle of internal lock headstock.

This utility model is achieved through the following technical solutions: a kind of can the bicycle of internal lock headstock, including by The V-arrangement vehicle frame that cylindrical shape seat pipe and square reinforcement inclined tube are linked to be, described inclined tube front end connection front fork tube, before this In breeches 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 overlapped Connect the seatpost of connection cushion, it is characterised in that: described inclined tube front end built-in carries button cell and display lamp Latch fitting, the dead bolt of this latch fitting is towards described front fork tube, the position that described front fork stem intersects with described inclined tube Arranging a coupling and insert the lockhole of described dead bolt, it is cylindrical that described dead bolt and described lockhole are.This handlebar When front fork stem described in hand-motion and bicycle front-wheel left-hand rotation 45 degree, described lockhole is directed at described dead bolt.

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

Further, described button cell connects into a series circuit with described display lamp, front fork stem and dead bolt, This series circuit conducting when this dead bolt inserts described lockhole, described display lamp lights, and represents that bicycle has locked.

Further, square described inclined tube front end side wall offers opening, the key hole of described latch fitting and institute State display lamp to expose from this opening, insert 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.

Detailed description of the invention

Please refer to Fig. 1 to Fig. 6, Fig. 1 be this utility model can the bicycle non-locking of internal lock headstock time knot Structure schematic diagram, Fig. 2 be this utility model can internal lock headstock bicycle locking time structural representation, 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, Fig. 5 Being the operation principle schematic diagram of latch fitting in Fig. 4, Fig. 6 is the principle schematic of display lamp in Fig. 4.This can be interior The bicycle of car locking head includes the V-arrangement vehicle frame being linked to be by cylindrical shape seat pipe 10 and square reinforcement inclined tube 20, described The seatpost 11 of seat pipe 10 upper end socket connection cushion 12.Described inclined tube 20 front end connection front fork tube 21, should In front fork tube 21, sheathed upper end is connected to handlebar 24, the front fork stem 22 of lower end connection front-wheel wheel shaft, and this is oblique Pipe 20 front end built-in one carries the latch fitting 30 of button cell 34 and display lamp 33.

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 button cell 34 connects into a series circuit with described display lamp 33, front fork stem 22 and dead bolt 31, This series circuit conducting when this dead bolt 31 inserts described lockhole 23, described display lamp 33 lights.

Described inclined tube 20 is square, and its front end side wall offers opening, the key hole 32 of described latch fitting 30 And described display lamp 33 exposes 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.Now, described button cell 34 and described instruction The series circuit connection that lamp 33, front fork stem 22 and dead bolt 31 connect, this display lamp 33 is bright.

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.
