Abstract

The utility model relates to a micro-adjustable braking-actuating hand lever for a bicycle. The utility model comprises a tubular screw bolt and a tubular screw cap, wherein, the screw bolt is provided with an outer screw, and the side body of a main body of the screw bolt is provided with a gully in a longitudinal way; the screw cap is provided with an inner screw, and the side body of a main body of the screw cap is also provided with a gully in a longitudinal way. Therefore, the screw bolt and the screw cap are formed in screw connection, which causes the head end of a brake wire to be arranged in the head part of the screw bolt. The internal steel cable of the brake wire is penetrated out from the body of the screw bolt and the screw cap. The screw bolt can be rotated to cause the brake wire to be loosened and fastened.

Description

Fine-tuning bicycle brake line bolt-stopping device

It is relevant that the utility model system and bicycle brake line end stud structure, more detailed it, refer to that especially firm the and fine-tuning bicycle brake line of a kind of assembling ends stud structure and improves.Belong to the bicycle brake accessory.

Press, the bicycle brake line ends a kind of structure as shown in Figure 1 of stud structure, and main system is a demihull shape, establishes a pair of district 1 that is referred to as to bring together on it, and this is brought district 1 together and after putting for brake cable 2, utilizes people's record book in accordion form around brake cable 2 is brought together; By above-mentioned known structure, following several drawbacks can appear on the implementation so:

1. utilize staff tabs body, usually one is injured easily accidentally;

2. it is improper to exert all one's strength sometimes, causes the lamellar body rhegma that wrecks;

3. clamping is not firm, can't effectively bring conduit together, often causes obscission.

In addition, have a kind of bicycle brake as shown in Figure 2 to end stud structure, main system establishes the brake cable support body 3 of symmetrical half opening up and down, and this brake cable 2 is placed in inner edge, and being subjected to up and down, two support bodys 3 pin down; And this structure also has some drawback:

1. the support body opening conforms to not to the utmost with the caliber of brake cable, sometimes also can escape;

2. for asking safety, the user often need utilize anchor clamps once more with support body folder bundle brake cable, very inconvenience;

Afterwards, occur a kind of only stud structure as shown in Figure 3 again, and improve the above-mentioned fraud that lacks though have, yet this bicycle brake line 2 contraction and relaxation can occur in the course of time, therefore makes very much the user puzzle one's brains.

Main purpose of the present utility model is: be intended to utilize the brake cable of the utility model to end the design of bolt structure, the phase can reach unlikely the coming off of fine-tuning and firm brake cable.

A kind of fine-tuning bicycle brake line bolt-stopping device of the utility model, it is characterized in that: this bolt-stopping device system comprises the nut of a tubular bolt and a tubulose, wherein, this bolt cording has outside thread, and lean to one side vertically to establish a dissected valley at its body, this nut then has negative thread in addition, and on body, also leaning to one side vertically to establish a dissected valley, in view of the above, this bolt and nut screw togather, and can be placed in the head of this bolt for the head end of a brake cable, and its inner cable wire stretched through body of bolt body and nut and went out, and rotatable bolt makes its brake cable stretch.

The utility model has the advantages that:

1. easy to operate, safety is stable;

2. easy to assembly and quick rapidly;

3. fine-tuning, the elasticity of this line body of may command.

The utlity model has following accompanying drawing:

The schematic perspective view of Fig. 1 for commonly using.

The schematic perspective view of Fig. 2 for commonly using.

The schematic perspective view of Fig. 3 for commonly using.

Fig. 4 is the three-dimensional exploded view of the utility model.

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

Fig. 6 is the combination cross-sectional schematic of the utility model.

Fig. 7 is the enforcement scheme drawing of the utility model.

Fig. 8 is the embodiment scheme drawing of the utility model.

Fig. 9 is another embodiment block diagram of the utility model.

Figure 10 is another embodiment block diagram of the utility model.

Number in the figure is as follows:

1. bring district's 2. brake cable, 3. support bodys together

4. cable wire 10 bolt-stopping devices 20. bolts

21. outside thread 22. dissected valleys 30. nuts

31. negative thread 32. dissected valleys 40. vehicle frames

50. weldering seated body

Now details are as follows for embodiment and conjunction with figs.:

At first, see also shown in Figure 4, a kind of fine-tuning bicycle brake line bolt-stopping device of the utility model, it is characterized in that: this bolt-stopping device 10 is the nut 30 that comprises a tubular bolt 20 and a tubulose, wherein, these bolt 20 cordings have outside thread 21, and lean to one side vertically to establish a dissected valley 22 at its body, this nut 30 then has negative thread 31 in addition, and is also leaning to one side vertically to establish a dissected valley 32 on body, in view of the above, this bolt 20 screws togather with nut 30, and can be placed in the head of this bolt 20 for the head end of a brake cable 2, and its inner cable wire 4 stretched through bolt 20 body bodies and nut 30 and goes out, and rotatable bolt 20, make its brake cable 2 stretch.

When assembling, see also Fig. 5 and shown in Figure 6, at first, this bolt 20 screws togather with nut 30, and its composite entity is welded in (shown in Figure 7) on the vehicle frame 40, and the head end of this brake cable 2 then can be placed in the head inside of this bolt 20, cable wire 4 within this brake cable 2 is pulled out outside stretched through bolt 20 and the nut 30 in addition again, and be engaged on another bolt-stopping device 10, as shown in Figure 7.

When operation, see also shown in Figure 8, because of this brake cable 2 stretches through when being combined on this bolt-stopping device 10, perhaps have relaxation after this brake cable 2 is used a period of time, at this moment, can utilize this bolt-stopping device 10 to make it to recover its tightness, and this bolt 20 rotations are promptly adjusted in its operation, cooperate brake cable 2 tightness, be adjusted to required tightness and get final product.

In addition the person be what deserves to be mentioned is, the bolt-stopping device 10 of the utility model on can being welded in vehicle frame 40 bodies separately, more divide into a weldering seated body 50 at bolt-stopping device 10, for this weldering seated body 50 and vehicle frame 40 welding also can, as Fig. 9 and shown in Figure 10.

Therefore, it is external that the utility model not only can apply to the bicycle brake line, more is used in fixing the ending on the stud structure of conduit on each vehicle, and the practical improvement of integral body and creativeness are extremely sure.
