Abstract
The invention discloses a bicycle capable of achieving internal locking of a front fork rod. The bicycle comprises a V-shaped frame formed by connecting a seat tube with a reinforced inclined tube, the front end of the inclined tube is communicated with a front fork tube, and the front fork rod is sleeved with the front fork tube, wherein the upper end of the front fork rod is connected with a handlebar, and the lower end of the front fork rod is connected with a front wheel axle. The bicycle is characterized in that a lock part is arranged in the front end of the inclined tube, a lock tongue of the lock part faces the front fork tube, the front fork rod is longitudinally provided with a lock groove, the lock tongue can be inserted into the lock groove in a width-matching mode, and when the handlebar drives the front fork rod and a front wheel to rotate leftwards by 45 degrees, the lock groove is aligned with the lock tongue. Compared with the prior art, the bicycle capable of achieving internal locking of the front fork rod has the advantages that the safe lock part is arranged in the bicycle and is not prone to be maliciously damaged, the front wheel fixedly rotates leftwards by 45 degrees after the bicycle is locked, the bicycle cannot move forwards, and the safety is high.
Description
Technical field
The present invention relates to a kind of bicycle, especially a kind of can the bicycle of internal lock front fork stem.
Background technology
Bicycle is a kind of light trip instrument, its unique convenience makes it be subject to numerous people to like, but the situation that bicycle is stolen is of common occurrence, how antitheft bicycle is becomes headachy problem always, existing theft-proof lock for bicycle is all generally be screwed on the vehicle frame sat below saddle, or adopts additional lock as through the steel ring of the front and back wheel of bicycle, lock is fixed in shackle lock, cable lock, D letter lock etc.These common locks all carry with car as bicycle annex usually, not only affect the good looking appearance of bicycle, and are easily pried open or cut off, and safety does not ensure.
Summary of the invention
The object of the invention is to overcome shortcoming of the prior art with not enough, provide a kind of safety high can the bicycle of internal lock front fork stem.
The present invention is achieved by the following technical solutions: a kind of can the bicycle of internal lock front fork stem, comprise the V-arrangement vehicle frame be linked to be by cylindrical seats pipe and square reinforcement inclined tube, described inclined tube front end is communicated with front fork tube, in this front fork tube, sheathed upper end is connected to handlebar, lower end connects the front fork stem of front-wheel wheel shaft, the seatpost of described seat pipe upper end socket connection cushion, it is characterized in that: the built-in latch fitting in described inclined tube front end, the cylinder shape lock tongue of this latch fitting is towards described front fork tube, described front fork stem is longitudinally arranged the locked groove that a width coupling inserts described dead bolt, this handlebar drive described front fork stem and front-wheel turn left 45 degree time described locked groove aim at described dead bolt.Because this locked groove is longitudinally arranged, adjustment handlebar locks this front fork stem to affecting described latch fitting during differing heights.
Compared to prior art, of the present inventionly the bicycle of internal lock front fork stem can be built-in with safety locking, not subject to malice damage, after locking, front-wheel is fixed left-hand rotation 45 degree bicycle cannot be moved ahead, and safety is high.
Further, square described inclined tube front end side wall offers opening, and the key hole of described latch fitting exposes from this opening, inserts for supporting key.
In order to the present invention can be understood more clearly, illustrate below with reference to accompanying drawing and set forth preferably embodiment of the present invention.
Accompanying drawing explanation
Fig. 1 be the present invention can the bicycle non-locking of internal lock front fork stem time structural representation.
Fig. 2 be the present invention 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 the present invention can the bicycle non-locking of internal lock front fork stem time structural representation, Fig. 2 be the present invention 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, and Fig. 4 is the perspective structure schematic diagram of front fork tube in Fig. 2.This bicycle of internal lock front fork stem can comprise the V-arrangement vehicle frame be linked to be by cylindrical seats pipe 10 and square reinforcement inclined tube 20, the seatpost 11 of described seat pipe 10 upper end socket connection cushion 12.Described inclined tube 20 front end is communicated with front fork tube 21, the front fork stem 22 that in this front fork tube 21, sheathed upper end is connected to handlebar 24, lower end connects 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, towards described front fork tube 21, described front fork stem 22 is longitudinally arranged the locked groove 23 that a width coupling inserts described dead bolt 31.This handlebar 24 drive described front fork stem 22 and bicycle front-wheel turn left 45 degree time described locked groove 23 aim at described dead bolt 31.Because this locked groove 23 is longitudinally arranged, adjustment handlebar 24 locks this front fork stem 22 to affecting described latch fitting 30 during differing heights.
Described inclined tube 20 is square, and its front end side wall offers opening, and the key hole 32 of described latch fitting 30 exposes from this opening, inserts for supporting key.
When needing to lock to bicycle, turned left 45 degree to make described locked groove 23 aim at described dead bolt 31, the key that turn is supporting by bicycle head, this dead bolt 31 stretches out and inserts the locked groove 23 on front fork stem 22, and the state of the now locked fixing left-hand rotation 45 of bicycle head, cannot promote bicycle again.
The present invention is not limited to above-mentioned embodiment, if do not depart from the spirit and scope of the present invention to various change of the present invention or distortion, if these are changed and distortion belongs within claim of the present invention and equivalent technologies scope, then the present invention is also intended to comprise these changes and distortion.
