Abstract

The utility model discloses a but bicycle of fork arm before internal lock, 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, it inserts vertically to set up width matching on the preceding fork arm the locked groove of spring bolt, this handlebar hand -motion preceding fork arm and front wheel turn left 45 when spending the locked groove is aimed at the spring bolt. Compared with the prior art, the utility model discloses a but bicycle of fork arm before internal lock embeds there is safe latch fitting, 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 can the bicycle of internal lock front fork stem

Technical field

This utility model relates to a kind of bicycle, a kind of can the bicycle of internal lock front fork stem.

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 front fork stem.

This utility model is achieved through the following technical solutions: a kind of can the bicycle of internal lock front fork stem, 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 connection front fork tube, should In front fork tube, sheathed upper end is connected to handlebar, the front fork stem of lower end connection front-wheel wheel shaft, described seat pipe upper end The seatpost of socket connection cushion, it is characterised in that: the built-in latch fitting in described inclined tube front end, the cylinder of this latch fitting Shape dead bolt is towards described front fork tube, and on described front fork stem, a longitudinally disposed width coupling inserts the lock of described dead bolt Groove, when this handlebar drives described front fork stem and front-wheel left-hand rotation 45 degree, described locked groove is directed at described dead bolt.Due to This locked groove is longitudinally disposed, does not interferes with described latch fitting and lock this front fork stem when adjusting handlebar to differing heights.

Compared to prior art, of the present utility model the bicycle of internal lock front fork stem safety locking can be built-in with, no Subjecting to malice to 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 be this utility model can the bicycle non-locking of internal lock front fork stem time structural representation.

Fig. 2 be this utility model can internal lock front fork stem 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.

Detailed description of the invention

Please refer to Fig. 1 to Fig. 4, Fig. 1 be this utility model can the bicycle non-locking of internal lock front fork stem time Structural representation, Fig. 2 be this utility model can internal lock front fork stem bicycle locking time structural representation, Fig. 3 Being 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. This bicycle of internal lock front fork stem can include the V-arrangement car that is linked to be by cylindrical shape seat pipe 10 and square reinforcement inclined tube 20 Frame, the seatpost 11 of described seat pipe 10 upper end socket connection cushion 12.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, the front fork stem 22 of lower end connection front-wheel wheel shaft, The built-in latch fitting 30 in this inclined tube 20 front end.

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 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 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.

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.

Claims
