Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of inner wiring type bicycle bowl set structure. BACKGROUND

[0002] Traditional bicycle needs brake cable and gear shifting to realize brake and gear shifting function, and common wiring mode is divided into outer wiring and inner wiring, and outer wiring installation and maintenance are relatively simple, with lower cost, and since cable is exposed, maintenance and replacement are more convenient, but cable is exposed, affecting the beauty of overall appearance, and cable is easily affected by external environment, such as silt and rainwater, increasing the risk of damage.

[0003] Since cable is hidden in the frame in inner wiring, overall appearance is more neat and beautiful, and cable is less disturbed by external environment, reducing the risk of accidental damage, but there is greater resistance when using: since cable moves in the frame, friction is greater, which can affect operation smoothness, and maintenance is more troublesome and costly: professional tools and skills are needed for maintenance, and cost is higher. SUMMARY

[0004] The utility model aims at solving the above prior art's insufficient, provide a kind of inner wiring type bicycle bowl set structure.

[0005] An inner wiring type bicycle bowl set structure, comprising a frame, the frame front end is equipped with hollow pipe, and the upper opening and the lower opening of hollow pipe are respectively equipped with upper bowl set and lower bowl set, the surface of upper bowl set and lower bowl set is equipped with let go of gap, and the gap is used for brake cable to pass through.

[0006] Further, the upper bowl set is equipped with through hole in the center, and the outer side wall of upper end port is equipped with outer circle check ring, and the lower bowl set is equipped with through hole in the center, and the outer side wall of lower end port is equipped with outer circle check ring.

[0007] Further, the material of upper bowl set and lower bowl set is metal material.

[0008] Further, the metal material is aluminum alloy or high carbon steel.

[0009] Further, the upper bowl set and lower bowl set are equipped with peeling in.

[0010] Further, the material of the frame is one of aluminum alloy, steel, titanium alloy, carbon fiber and magnesium alloy.

[0011] Advantages: compared with prior art, the utility model has the following advantages:

[0012] By setting the let gap on the surface of the upper bowl group and the lower bowl group, the brake line can smoothly pass through, avoiding the problem of exposed brake line in traditional design, not only improving the aesthetics, but also reducing the safety hidden trouble in riding, and through the hollow pipe at the front end of the frame, the wiring is more convenient;

[0013] The center of the upper bowl group and the lower bowl group is provided with a through hole, and the outer side wall of the port is provided with an outer round check ring, which not only ensures the stable installation of the bowl group, but also enables the brake line and other related components to pass through and be fixed in order, enhancing the overall structure and stability.

[0014] The upper bowl group and the lower bowl group are made of metal materials (such as aluminum alloy or high carbon steel), which have good strength and wear resistance, and can ensure that the bowl group maintains stable performance in long-term use. At the same time, the material selection of the frame is diversified, including aluminum alloy, steel, titanium alloy, carbon fiber, magnesium alloy, etc., which can be selected according to different needs and budget to meet the needs of different consumers.

[0015] The bowl group is provided with a bearing, which effectively reduces the friction and resistance during rotation, and improves the smoothness and comfort of riding. BRIEF DESCRIPTION OF DRAWINGS
