Description

Bicycle accessories fixed structure

The invention relates to the field of bicycles, in particular to a fixed structure for parking bicycles and bicycle accessories.

With the progress of the times, modern people are quite satisfied with basic food, clothing, housing and transportation, and begin to move in the direction of self-realization. The rise of sports trends should also follow this direction. Modern people are very interested in riding bicycles, which can be used for transportation. There is great interest in activities that allow people to travel back and forth and exercise on the side. Therefore, the bicycle industry has a trend of becoming increasingly popular.

Unlike motorcycles, ordinary bicycles have center pillars and side pillars that are directly set up on the motorcycle body to assist the motorcycle in parking. Bicycles usually use additional parking pillars that are directly locked on the rear frame of the bicycle to assist in parking. This additional locked parking pillar Not only is it more difficult to disassemble and assemble, but the combined structure is not stable enough and can easily become loose from the bicycle frame in a short period of time with continued use.

Therefore, some manufacturers have set up another type of parking rack. By installing an additional assembly piece on the hook part of the bicycle frame and installing the parking column on the hook part assembly piece through the through-axis, the parking column can be installed more stably. On the rear wheel of a bicycle, increase the life of parking posts.

However, this method requires an additional assembly piece to be added to the hook portion of the bicycle, which is quite difficult and costly to install. At the same time, if the assembly piece is not installed properly, the parking column may easily come loose.

At the same time, in the past, bicycle rear racks were usually fixed only with through-shafts and screws. Therefore, after being used for a period of time, they were easily affected by the separation force of bicycle vibrations, causing them to loosen, which would lead to danger and were quite unsatisfactory in terms of durability.

The main purpose of the present invention is to provide a bicycle accessory fixing structure. By setting a recessed groove on the bicycle and a stable block on the fixed base and combining them, the fixed base can be stably and not easily loosened on the bicycle. Then the bicycle accessories are installed on the fixed base. This structure increases the stability of the connection between the bicycle accessories and the bicycle to extend the service life. At the same time, the ease of assembly is still simple, making the bicycle accessories more practical.

In order to achieve the above objects and effects, the present invention provides a bicycle accessory fixing structure, which is used to be installed on a bicycle frame, including a fixed seat, a through shaft and a parking column, wherein the bicycle frame is provided with a first hook portion and a second hook portion. The first hook portion includes an outer veneer facing the outside, and the first hook portion is provided with an assembly hole penetrating the outer veneer. The outer veneer is provided around the assembly hole. There are concave grooves arranged at intervals.

Next, the fixed seat is located outside the outer veneer, and the fixed seat is provided with a ring portion at one end and a pivot hole at the other end. The ring portion includes an inner veneer facing the outer veneer. And the set of rings is provided with an assembly hole penetrating the inner veneer. The inner veneer is provided with stabilizing blocks arranged at intervals around the assembling hole. The position of the stabilizing blocks corresponds to the recessed groove. The stabilizing blocks are placed into the recessed groove.

Finally, the through shaft passes through the assembly hole and the assembly hole, and the fixed base is assembled on the first hook part. In addition, the parking column is pivoted on the pivot hole.

In order to achieve the purpose and effect, the present invention also provides a bicycle accessory fixing structure, which is used to be installed on a bicycle frame, including a fixed seat and a parking column, wherein the bicycle frame is provided with an external part, and the external part is provided with a first A combination surface is provided with an assembly hole on the external portion, and the first combination surface is provided with spaced-apart recessed grooves around the assembly hole.
