Abstract

The utility model relates to a bicycle braking wire bend tube which downwards extends to a braking wire from a braking handgrip, and the braking wire penetrates through a bend tube which is connected with a V-shaped brake, and is coated and protected by an elastic and telescopic hose after penetrating through the bend tube to prevent steel cables in the braking wire from being damaged. The bend tube has a flexible tube body which is formed by spirally arranging metal wires, and the steel cables of the braking wire penetrate through the flexible tube body. Therefore, the braking wire is not limited by the angle of the bend tube so that the safe operation of the brake can not be affected when the brake brakes.

Description

Bicycle brake line bend pipe

The utility model system is relevant with the brake cable bend pipe structure, more detailed it, but refer to that especially a kind of conveniently adjusting angle do not limit orientation and the good bicycle brake line of safety to bend.Belong to the bicycle brake accessory.

The structure of general in the past brake cable bend pipe, as shown in Figure 1, it mainly is by a brake cable 1 of extending on this from the Brake lever (not shown) bend pipe 2 that stretched through, and be connected on the V-type brake 3, and this brake cable 1 is passed the rubber coiled pipe 4 that a tool telescopic resilience is arranged behind the bend pipe 2 and is coated protection; Right said structure is some drawback below regular meeting's appearance when implementing:

1, this bend pipe 2 is a metallic steel hardware, its bending arc angle is fixing during global formation, this brake cable 1 stretches through and can't adjust change with the fit angle of this brake, therefore, if meet under the situation that the Brake lever that between the sexes there should be a prudent reserve need be adjusted, its be connected in 1 of brake cable on the handle can't take advantage of a situation make appropriateness the adjustment deallocation should the angle of the bend pipe 2 of fixed angle and brake 3.

2, fix its angle because of this bend pipe 2, and brake 3 itself also is fixed on the vehicle frame, therefore if not just during best angle, the start that when backguy is braked, then can have some setbacks of this brake cable 1, make this bend pipe 2, brake 3 and coiled pipe 4 push, and make that the folder bundle brake on this brake 3 is uncertain; Cause danger easily (as shown in Figure 2).

Main purpose of the present utility model is: a kind of bicycle brake line bend pipe is provided, utilizes the bend pipe structure design of the utility model, the phase can reach the more convenient adjustment angle and the safer purpose of braking.

A kind of bicycle brake line of the utility model bend pipe, it is the brake cable of extending on Brake lever by, the bend pipe that is connected with a V-type brake and this brake linear system stretched through, and this brake cable stretched through behind the bend pipe, there is the coiled pipe of an elastic telescopic to coat protection, avoids the interior cable wire of brake cable impaired; It is characterized in that: this bend pipe is the pliability body of a metal wool helical arrangement formation, the cable wire of this brake cable of confession stretches through in it, in view of the above, can make assembling and user adjust suitable angle arbitrarily, reaching best braking effect, and the phase can make brake cable not be subjected to the bend pipe angle limits and the safe start of brake when influencing brake.

The utlity model has following advantage;

1, angular adjustment is convenient, not limited by the orientation;

2, brake is smooth and easy, and safety is good;

3, assembling is suitable for any car type easily, but cost-cutting.

The utlity model has following accompanying drawing:

The three-dimensional exploded view of Fig. 1 for commonly using.

The scheme drawing of Fig. 2 for commonly using.

Fig. 3 is the three-dimensional exploded view of the utility model.

Fig. 4 is the assembled sectional view of the utility model.

Fig. 5 is the scheme drawing of the utility model.

Number in the figure is as follows:

1 brake cable, 2 bend pipes, 3 brakes

4 coiled pipes, 10 brake cable, 11 cable wires

20 brakes, 30 bend pipes, 40 coiled pipes

Now lift preferred embodiment and conjunction with figs. is described as follows:

At first, see also shown in Figure 3, a kind of bicycle brake line of the utility model bend pipe, it mainly is from the Brake lever (not shown) by one, the brake cable 10 of extending, and this brake cable 10 is the bend pipe 30 that is connected with a V-type brake 20 that stretched through, and this brake cable 10 stretched through behind the bend pipe 30, there is the coiled pipe 40 of an elastic telescopic to coat protection, avoids the interior cable wire 11 of brake cable 10 impaired; And wherein,

This bend pipe 30 is the pliability body of a metal wool helical arrangement formation, stretches through for the cable wire 11 of this brake cable 10, and the phase can make brake cable 10 not be subjected to bend pipe 30 angle limits and the safe start of brake 20 when influencing brake in view of the above.

When combination; see also Fig. 4 and cooperate shown in Figure 3; this brake cable 10 is extended when getting off from Brake lever; general this brake cable 10 coats a plastic skin in cable wire 11 peripheral meetings; and arrive when being extended through within the bend pipe 30; then this brake cable 10 can be exposed an end cable wire 11 for each assembly of below that stretched through; therefore; the brake cable 10 of whole piece is passed in this pliability bend pipe 30 with cable wire 11 lines by to bend pipe 30 time; and this bend pipe 30 is to be connected in one of this V-type brake 20 end; so 11 of cable wires bend pipe 30 that stretched through within this brake cable 10; the elastic telescopic coiled pipe 40 of brake 20 1 ends and a tool protectiveness then is connected in one of brake 20 starts end, then forms whole group brake structure.

When operation, because of this bend pipe 30 is to belong to a flexible metal pipe structure, the angle of bend pipe 30 can unrestrictedly be adjusted, so the interlock angle that cooperates of this brake cable 10 and brake 20 also can be unrestricted and influence the smoothness (as shown in Figure 5) of brake.

It will be further appreciated that; because of this Brake lever regular meeting is provided with because of the position of men and women's gripping is different; but because of the brake cable bend pipe of commonly using 2 be a fixed type hardware; can't cooperate its position to do its adjustment; and the brake cable bend pipe of front and back wheel often is different angle (the trailing wheel person is general, and angle is bigger); so adjusting its angle is not easy especially; therefore; not only dealer or user often undertake to do what is apparently beyond one's ability for it; so usually cause aforementioned drawback and dangerous the generation; yet the utility model not only makes the drawback of commonly using improve its structure do one improvement, more makes the convenient use of user and safer.

Claims
