Combination structure of pedal and mandril of bike

Abstract

The invention relates to a combination structure of a pedal and a mandril of a bike. The combination structure comprises the mandril, a clamping sleeve part and the pedal, the clamping sleeve part can be rotatably positioned outside the mandril in a penetrating and sleeving mode, the outer wall of the clamping sleeve part is provided with at least one hook claw, the pedal comprises a mandril penetrating pivot portion, the inner wall of the mandril penetrating pivot portion is provided with steps, and the hook claws hook the steps. According to the combination structure of the pedal and the mandril of the bike, the pedal is not combined with the mandril, therefore, the left-right width of a bike body can be decreased due to the fact that no pedal is arranged, the width of an external package box is specifically decreased, and then the wood volume number of the external package box is decreased; the stability of the bike body in the external package box is high, the using amount of buffering filler filled in the space can be decreased, the total weight of the packaged bike is further decreased, and the freight transportation cost is lowered; the pedal can be independently assembled by a user, and assembling is easy; the pedal can be stably combined in the clamping sleeve part, and therefore it is guaranteed that the pedal cannot be separated from the mandril; the user can freely select the style of the pedal according to the hobby.

Description

technical field [0001] The invention relates to a combined structure of a bicycle pedal and a mandrel, in particular to a combined structure of a bicycle pedal and a mandrel which can be installed on the mandrel by the user. Background technique [0002] When the pedal and the spindle of the existing bicycle are assembled, since the pedal and the spindle need to be combined through components such as self-lubricating bushings, ball bearings, and several screw locks, and each component needs to pass through a predetermined The assembly process is installed at the predetermined position with appropriate tools. The assembly process is professional and complicated, and it is not possible for ordinary people without professional training. Therefore, it is assembled into a complete kit by the manufacturer and then delivered to the vehicle assembly plant. Assembled on the crank of the finished car. [0003] Based on the above procedures, the packaging plant is faced with the probl...

AI Technical Summary

Problems solved by technology

Because the pedals and mandrels are assembled into the finished vehicle in kits, the left and right width of the finished vehicle will be wider due to the length of the pedals, making the width of the outer box larger, and the delivery of the finished vehicle needs to be delivered by freight, sea, air, etc. Way, and the shipping cost is calculated based on the volume of the outer box (length x width x height x base) or the total weight. When the volume becomes larger, the relative freight cost increases

In addition, the larger the width of the outer box, the left and right distance between the bicycle body and the outer box will increase, and the space will become larger. More buffer fillers must be filled in the space to ensure the stability of the bike body in the outer box. Cushion fillers also add to the total package weight, resulting in increased freight costs
