Bicycle catheter

The present invention relates to a bicycle catheter, and more particularly to a catheter that is placed on the surface of a bicycle wire and that slides the bicycle wire.

According to the fact that the use of bicycles has always been the simplest and most traditional means of transportation for human beings. With the promotion of bicycle leisure and the promotion of competition, it is becoming more and more common for office workers to commute to and from work by bicycles. Many bicycle riders also use the holiday and leisure time to meet the bicycle iron horse driveway. They can not only enjoy beautiful scenery along the road, but also enjoy fresh air and enjoy sports and leisure. Even some local governments do not regularly hold bicycle races. Related activities attract bicycle riders to challenge and participate. However, if the bicycle is to be stopped during driving, it is necessary to rely on the brake system to reduce the speed of the wheel and reach the static state. Therefore, the brake wire of the brake system is one of the bicycle structures. Important link.

In the past, the bicycle wire 4 has a tubular outer sleeve 41 and an inner wire 42 (see FIG. 16), and the inner wire 42 can be inserted into the outer casing 41 and passed through the outer casing 41. The wire 4 is generally referred to as a Bowden type bicycle brake wire 4, and the outer casing 41 of the typical Bowden brake wire 4 has a lining 411 made of synthetic resin, the outer side surface of which is adjacent to the lining. Slide 411 and slide; a flat steel wire 412, The spiral winding is applied to the outer circumference of the lining 411; and a sheath 413 is made of synthetic resin and is sleeved on the outer circumference of the flat steel wire 412. The inner wire 42 of the typical Bowden brake wire 4 is made of a entangled steel wire that protrudes beyond both ends of the outer casing 41 and each end of the inner wire 42 is connected to a manually operated component or a wire. The operating member is thereby operated to operate the inner wire 42 in the sliding state of the outer casing 41 to achieve the braking effect.

However, in the above-mentioned conventional sense, a typical Bowden brake wire 4 is composed of a jacket 41 and an inner wire 42 that can be inserted into and passed through the outer casing 41, and the inner wire 42 protrudes beyond the outer casing 42 Both ends of the outer casing 41 and the ends of the inner wire 42 are connected to a manual operation member or a wire operating member to make the inner wire 42 slide in the outer casing 41 to achieve the braking effect; however, due to the outer casing 41 The flat steel wire 412 is spirally wound to the outer circumference of the lining 411. When the flat steel wire 412 is pressed by an external force, the deformation phenomenon is easily caused, so that the inner wire 42 cannot be in the lining 411 of the outer casing 41. Sliding smoothly affects the braking effect, which is easy to cause danger. It is still a major drawback in terms of safe use, and needs to be improved.

The present invention provides a bicycle catheter which is sleeved on a surface of a bicycle wire and has a sliding state for the bicycle wire. The catheter is continuously spirally connected by a linear body to present a spiral body, and the spiral body of the spiral body is rotated. The connecting line presents a plurality of equidistant pitches, and the spiral body is provided with an accommodating space corresponding to the upper and lower ends of the spiral body; and two holes are fixed on the outer edge of the spiral. a strip at the outer side of the body to The spiral body is prevented from being axially pressed by an external force to be in a stretched shape.

Wherein the shaped strip at the outer side of the body of the spiral is fixed by either parallel or spiral; wherein the shaped strip at each side of the body of the spiral is represented by a plurality of strips; wherein the line of the spiral The outer diameter of the continuous convolution of the body is uniform; wherein the conduit further comprises a liner disposed at the receiving space of the spiral body for the bicycle wire to be inserted therein; wherein the spiral is in the liner The bicycle wire is made of any one of a steel wire, a stainless steel wire or a titanium wire; wherein the outer circumference of the spiral body is further provided with a coating layer covering the outer circumference of the spiral body; The accommodating space in the spiral body of the catheter can be directly disposed for the bicycle wire; wherein the outer circumference of the spiral body can be further provided with a coating layer covering the outer circumference of the spiral body.

The main purpose of this creation is to provide a catheter that is placed over the surface of the bicycle wire and that allows the bicycle wire to slide.

The bicycle catheter of the present invention is a catheter which is arranged on the surface of the bicycle wire and has a sliding state of the bicycle wire; wherein the conduit is continuously spirally connected by a linear body to present a spiral body, and the linear body of the spiral body is connected to the spiral system. Presenting multiple equidistant festivals And the accommodating space corresponding to the upper and lower ends of the spiral body; wherein the duct further comprises a liner disposed at the accommodating space of the spiral body and Providing a bicycle wire through; the fixed outer strip fixed at the outer side of the wire body is provided at the outer edge of the spiral body to prevent the spiral body from being axially pressed by the external force to be expanded and deformed; The liner in the space is not deformed by any external force against the pressing factor, so that the bicycle wire can smoothly slide in the liner of the catheter; thereby providing a sleeve on the surface of the bicycle wire and A conduit for the bicycle wire to slide.
