Description

bicycle tube fastening device

technical field

The utility model relates to a fastening device between an upper pipe and a vertical pipe, in particular to a bicycle pipe fastening device.

Background technique

Riding a bicycle has the characteristics of traveling far and taking into account environmental protection. In today's stressful leisure life, engaging in outdoor leisure activities to experience nature can achieve sports and health at the same time. It can not only exercise the body but also nourish the mind. It is a sport suitable for modern people one. With the implementation of the two-day weekend and the establishment of special bicycle lanes in various places, people have a lot of leisure time and exercise space. Therefore, with the improvement of living standards today, the bicycle market is more valued by the public.

Generally, the rear wheel of a bicycle is kept in the same direction as the frame, and the front wheel of the bicycle can be driven by the handle to swing, thereby changing the steering angle of the front wheel to achieve the purpose of steering or turning the bicycle, and using the swing handle to help maintain the rider. The center of gravity of the body maintains the balance of the two wheels of the bicycle to ensure the safety of bicycle riding. The handlebar of the bicycle is assembled and connected with the upper tube of the front fork by the standpipe, which can prolong the distance between the handlebar and the upper tube of the front fork by the vertical tube extending forward, so that the steering action of the bicycle is tended to be gentle.

In the existing connection structure between the vertical tube and the upper tube of the front fork, in addition to using the hoop at one end of the vertical tube to cooperate with the side bolts to fasten the upper tube of the front fork, there is also a tightening component to form the front fork The combination of the upper tube and the vertical tube; this pressing assembly includes a pressing piece arranged in the upper tube of the front fork, a cover arranged on the top surface of the upper tube of the front fork, and a lock between the cover and the pressing The bolts between the tightening plates are mainly due to the locking effect of the bolts, so that the standpipe and the head cup on the frame are tightened, so that the proper stability between the front fork upper tube and the frame can be maintained.

After the bicycle has been ridden for a period of time, the locking force of the screws of each structure will gradually disappear due to vibration, impact, etc. during the movement, and the pipes will loosen by themselves, such as the non-linear alignment of the standpipe and the front wheel (that is, both There is an angle difference between them), when riding, it is found that the bicycle is moving to the right or to the left, and it is difficult for the owner to control the straight direction of the bicycle, so it is necessary to adjust the standpipe to restore the original position. However, when adjusting the position of the standpipe, it is necessary to loosen the bolts first and then remove the cover, then loosen the bolts on the side of the standpipe hoop, so that the hoop of the standpipe can be rotated to the correct angle relative to the upper tube, and then reversed after adjustment Repeat the above actions. Do not lock and fix at one time when locking repeatedly. You need to lock the cover gently, and temporarily fix the side screws of the hoop. After turning the handle to check whether the handle turns smoothly, lock the bolts and side screws.

From the above, it can be seen that the existing overall required components are complicated, which also makes it have the disadvantages of time-consuming manufacturing and increased manufacturing costs. In addition, the existing structure has the disadvantage of wasting time for adjustment.

In order to improve the above-mentioned defects, the inventors have carried out research and development and design for many years, and finally created a bicycle tube fastening device, which achieves low production cost and has the effect of quick installation and adjustment of the vertical tube.

Utility model content

The technical scheme that the utility model solves its technical problem adopts is:

A bicycle tube fastening device is characterized in that it is arranged between the upper tube and the vertical tube, and includes: two lining rings, one end of which is provided with an insertion part and the other end is provided with a stopper part, and the lining ring is arranged around the There is an adjustment gap between the penetrating insertion part and the locking part on the side. Each lining ring is respectively inserted and fixed in the upper and lower hole walls of the shaft hole of the vertical pipe with the insertion part, and each lining ring is respectively locked with its locking part. Arresting against the outer edge of the upper and lower holes of the shaft hole, the lining ring is used for the upper pipe to pass through; a pressing assembly includes a pressing piece arranged in the upper pipe, a sealing ring assembled on the upper hole edge of the shaft hole, and A bolt is threaded and locked between the cover and the tightening piece, and the cover is fastened to the lining ring by screw locking, and the standpipe is positioned on the upper tube at the same time.

In the aforementioned bicycle tube fastening device, the adjustment gap is oblique.

In the aforementioned bicycle tube fastening device, the insertion part is perpendicular to the direction of the tightening piece from the stopper part.

In the aforementioned bicycle tube fastening device, the insertion portion is tapered from the locking portion toward the tightening piece.

The beneficial effect of the utility model is that, in addition to quickly installing the vertical pipe assembly on the upper pipe, it also provides users with the ability to quickly adjust the vertical pipe to restore the correct position, and its structure is simplified to effectively reduce the production cost.
