Description

A kind of bicycle of the built-in latch fitting of vehicle frame band

Technical field

The utility model relates to a kind of bicycle, the bicycle of a kind of built-in latch fitting of vehicle frame band.

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 iron 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 annex onboard, not only affects the good looking appearance of bicycle, and is easily prized Opening or cut off, security 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 security is high The bicycle of the built-in latch fitting of vehicle frame band.

The utility model is achieved through the following technical solutions: the bicycle of a kind of built-in latch fitting of vehicle frame band, bag Including the V-arrangement vehicle frame being linked to be by cylindrical shape seat pipe and square reinforcement inclined tube, described inclined tube front end connects front fork tube, In this front fork tube, sheathed upper end is connected to handlebar, the front fork stem of lower end connection front-wheel wheel shaft, in described seat pipe The seatpost of end socket connection cushion, it is characterised in that: described inclined tube front end built-in carries button cell and refers to Showing the latch fitting of lamp, the cylinder shape lock tongue of this latch fitting is towards described front fork tube, on described front fork stem longitudinally disposed one Width coupling inserts the locked groove of described dead bolt, this handlebar drive described front fork stem and front-wheel turn left 45 degree time institute State locked groove and be directed at described dead bolt.Owing to this locked groove is longitudinally disposed, adjust handlebar to will not shadow during differing heights Ring described latch fitting and lock this front fork stem.

Compared to prior art, the bicycle of the built-in latch fitting of vehicle frame band of the present utility model is built-in with head lock, no Subjecting to malice to damage, after locking, the fixing left-hand rotation of front-wheel 45 degree makes bicycle to move ahead, and security is high.

Further, described button cell connects into a series circuit with described indicator lamp, front fork stem and dead bolt, This series circuit conducting when this dead bolt inserts described lockhole, described indicator 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 indicator lamp to expose from this opening, insert for supporting key.

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

Detailed description of the invention

When being the bicycle non-locking of the utility model built-in latch fitting of vehicle frame band please refer to Fig. 1 to Fig. 6, Fig. 1 Structural representation, Fig. 2 is the structural representation during locking of the bicycle of the utility model built-in latch fitting of vehicle frame band Figure, Fig. 3 is the perspective structure schematic diagram of front fork tube in Fig. 1, and Fig. 4 is the perspective structure of front fork tube in Fig. 2 Schematic diagram, Fig. 5 is the operation principle schematic diagram of latch fitting in Fig. 2, and Fig. 6 is that in Fig. 4, the principle of indicator lamp is shown It is intended to.The bicycle of this built-in latch fitting of vehicle frame band includes being linked to be by cylindrical shape seat pipe 10 and square reinforcement inclined tube 20 V-arrangement vehicle frame, described seat pipe 10 upper end socket connection cushion 12 seatpost 11.Described inclined tube 20 front end Connection front fork tube 21, in this front fork tube 21, sheathed upper end is connected to handlebar 24, lower end connects front-wheel wheel shaft Front fork stem 22, this inclined tube 20 front end built-in one carries the latch fitting 30 of button cell 34 and indicator lamp 33.

The cylinder shape lock tongue 31 of this latch fitting 30 is towards described front fork tube 21, longitudinally disposed on described front fork stem 22 One width coupling inserts the locked groove 23 of described dead bolt 31.This handlebar 24 drives described front fork stem 22 and bicycle During front-wheel left-hand rotation 45 degree, described locked groove 23 is directed at described dead bolt 31.Owing to this locked groove 23 is longitudinally disposed, adjust Do not interfere with described latch fitting 30 when handlebar 24 is to differing heights and lock this front fork stem 22.

Described button cell 34 connects into a series circuit with described indicator lamp 33, front fork stem 22 and dead bolt 31, This series circuit conducting when this dead bolt 31 inserts described lockhole 23, described indicator 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 indicator lamp 33 exposes from this opening, insert for supporting key.

When needing to lock to bicycle, described locked groove 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 locked groove 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 indicator lamp 33 is bright.

The 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 the utility model is also intended to comprise these changes and deformation.
