Description

Improvement of the head bowl structure of the inner wiring

This creation is about an improvement of the head bowl structure of the inner wiring, especially a bearing structure that can hide the wiring in the head tube, which can avoid the clutter of the wiring, and provide the function of hiding and protecting the cable.

Bicycles usually have many cables used to actuate bicycle components. Usually these cables are often routed along the outside of the bicycle frame and components, which can easily cause clutter problems, affect the overall appearance of the body, and during bicycle riding, It is also easy to accidentally pull the exposed cable, causing damage to the cable. In order to solve the above problems, some manufacturers have changed the cable to use the internal space of the frame to route the cable, which is to pass the cable through the handle tube, the front bowl, the front fork tube and the inside of the frame, so that the cable is routed as much as possible. Inside the frame to avoid clutter.

However, in order to hide cables such as brakes and shifting cables in the conventional structure to make the appearance of the bicycle body more concise, the front headset must be specially designed, that is, the use of special specifications is restricted, which often causes the user to increase the purchase cost and Troubles during installation, the overall structure does need to be improved.

This creation provides an improvement to the structure of the front bowl of the inner cable, which includes: a front fork tube; a head tube, which is arranged at the front end of a bicycle frame; a bearing; A sleeve hole is provided with at least one through hole in the axial direction at a preset position between the socket and the sleeve hole; The upper part and the head tube are passed through each other, and then the bottom of the socket and the bearing are passed through each other, and then the bearing and the socket are sleeved above the head tube, and the socket sleeve hole and the front fork The tubes pass through each other so that the upper cover is covered on the bearing and the socket, and the perforation and the front fork tube pass through each other, and at least one cable is inserted into the perforation hole through the upper cover through hole and hidden Inside the head tube; through the above-mentioned components, cables such as brake cables or transmission cables can be inserted into the through holes through the through holes, and enter the inside of the head tube, so that the cables will not be exposed to the outside and avoid clutter. Those who provide the function of hiding and protecting cables are truly innovative, convenient and practical.

The improvement of the head bowl structure of the inner wiring of this creation is that a socket is provided between the head tube and the upper cover, the socket is provided with a through hole, and the upper cover is provided with a through hole corresponding to the through hole to make the brake line Cables such as transmission cables or transmission cables can be inserted into the through holes through the through holes and enter the inside of the head tube, so that the cables will not be exposed to the outside, avoiding clutter, and providing cable hiding and protection functions; The inner circumference of the bearing sleeve hole is formed with a first ring slope with a downwardly tapered aperture, and the outer circumference of the bottom of the beam ring forms a downwardly tapered second ring slope. The waterproof ring is covered on the head tube and the bearing. The first ring slope of the seat and the second ring slope of the beam ring can achieve mutual tightening effect and provide the steering function; It is more convenient for thread management and replacement; each of the upper covers and sockets can be used for plastic injection of hard materials, such as nylon, POM, PP or glass fiber applications; the upper cover can be a circular design to facilitate application On existing models; the top cover can also be a special-shaped design to match different exterior designs of the frame.
