Description

Bicycle modularization cavity crank convenient to adjust

Technical Field

The utility model relates to the technical field of bicycles, in particular to a bicycle modular hollow crank convenient to adjust.

Background

Bicycles, also known as bicycles or bicycles, are typically two-wheeled small land vehicles. After a person rides a bicycle, the person steps on a pedal as power, the bicycle is a green and environment-friendly vehicle, and more people use the bicycle as fitness equipment for riding exercise and traveling; the bicycle itself also is a sports competition, has highway bicycle match, mountain bike match, place bicycle match, stunt bicycle match etc. and relevant parts such as the crank on traditional bicycle are firm each other together, takes place the condition back that damages when one of them part, and inconvenient user dismantles by oneself and changes, and certain trouble that the use of giving the user brought.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

Aiming at the defects of the prior art, the utility model provides the bicycle modular hollow crank convenient to adjust, and solves the problems in the prior art.

(II) technical scheme

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a bicycle modularization cavity crank convenient to adjust, includes crank module, fluted disc module and axle center module, the lateral wall both ends of axle center module all are connected with through self-discharging screw dismantlement the crank module, just the lateral wall of axle center module is close to the left side crank module department is fixed with through lock nut the fluted disc module.

Preferably, the modular hollow crank is provided with a regulating ring in a matching way.

(III) advantageous effects

The utility model provides a bicycle modular hollow crank convenient to adjust, which has the following beneficial effects:

the crank module is arranged on the axis module through the self-unloading screw, the fluted disc module is fixed on the axis module through the locking nut, and when one module is damaged, a user can conveniently and quickly replace the damaged module, so that the use of the user is greatly facilitated; in addition, the bicycle is also provided with an adjusting ring, when the bicycle is used, the adjusting ring is sleeved on the axle center module, and after the position of the adjusting ring is adjusted, the adjusting ring is fixed on the axle center module by using a hexagonal screw, so that the condition that the bicycle bearing is abraded and dislocated is avoided; and dismantle through the self-discharging screw and change the crank module and can ride the height of driving according to the difference and change different crank modules to can adapt to different crowds, and the axle center module can be changed into the axle center module of different length according to the type of different bicycles, and more person of facilitating the use uses.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

As shown in fig. 1-3, the present invention provides a technical solution: a bicycle modular hollow crank convenient to adjust comprises a crank module 2, a fluted disc module 3 and an axle center module 4, wherein both ends of the outer side wall of the axle center module 4 are detachably connected with the crank module 2 through self-discharging screws 1, when the crank module 2 is detached, a vertical tube hexagon nut is inserted into the self-discharging screws 1, then the self-discharging screws 1 are rotated, the crank module 2 can be detached from the axle center module 4, compared with the traditional crank detaching mode, the mode is more convenient and rapid, in addition, when the crank module is installed, the reverse operation can be carried out, the fluted disc module 3 is fixed on the position, close to the left crank module 2, of the outer side wall of the axle center module 4 through a locking nut, when the fluted disc module 3 is detached, the crank module 2 is detached firstly, then the locking nut 6 is loosened, then the fluted disc module 3 is detached from the axle center module 4, the modular hollow crank is provided with an adjusting ring 5, when the bicycle is used, the adjusting ring 5 is sleeved on the axle center module 4, and after the position of the adjusting ring 5 is adjusted, the adjusting ring is fixed on the axle center module 4 by using a hexagonal screw, so that the condition that the bicycle bearing is abraded and dislocated is avoided.

In conclusion, the working process of the utility model is as follows: when the bicycle axle center module is used, the axle center module 4 is installed on a bicycle, the adjusting ring 5 is sleeved on the axle center module 4, the position of the adjusting ring 5 is adjusted, the adjusting ring is locked by using a hexagonal screw, the locking nuts 6, the fluted disc modules 3 are sequentially sleeved on the axle center module 4, the fluted disc modules 3 are fixed on the axle center module 4 by using the locking nuts 6, and finally, the two crank modules 2 are respectively sleeved on the axle center module 4 and are fixed by using the self-discharging screws 1.

It should be noted that, in this document, relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
