Description

Quick joint device for disc brake pipe

This creation relates to a disc brake, and in particular to a technical scope of a gap adjustment device that can be used for a brake pad.

According to the hydraulic brake system currently applied to bicycles, the utility model mainly comprises: a handlebar for attaching a bicycle handlebar, a brake caliper installed on the side of the wheel, and a hydraulic oil pipe connecting the two, wherein the hydraulic oil pipe system is hydraulic The oil is guided from the handle of the brake to the brake caliper to drive the brake caliper to generate the brake action, and the brake caliper includes at least one brake starter, a pipeline and a brake pad, and the brake starter includes at least one brake a force member and a chamber for receiving a fluid such as hydraulic oil, the force applying member for applying the fluid to cause the fluid to transmit a pressure to the brake block, such that the brake block is driven and contacts a A brake mechanism occurs in the disc, and the pipeline has a hydraulic oil body, and the two ends of the brake motor and the handle of the brake are respectively connected to each other to form a hydraulic transmission system.

Generally, the brake block has a gap distance with the disc piece, and the gap is related to the braking force and the reaction time of the brake. The large gap generates a small braking force and a long time required for braking, and the gap is small to generate the braking force. It takes a long time to get on the bus.

Therefore, the employed person developed the domestic new patent No. M427339 "Adjustment device for the position of the brake of the hydraulic brake brake", which discloses the right screw (621) and the left screw of the outer kit (62). The tooth (622) is designed to rotate the outer sleeve (62) to drive the first set (64) and the second set (66) to perform separate or close positioning operations, thereby changing the line (14) The length causes the volume of space between the inner sleeve (68) and the first passage (641) to change. For example, the first kit (64) and the second kit (66) perform close positioning actuation, and then the space volume becomes smaller, and the transmission of hydraulic oil causes the two brake discs (282) of the brake brake (28) to be pushed. The proximity positioning action can be used to delay the reaction time of the vehicle, and vice versa, the reaction time of the brake is delayed.

However, in the above-mentioned conventional adjusting device, the right screw (621) and the left screw (622) of the outer sleeve (62) respectively generate friction with the first sleeve (64) and the second sleeve (66). Very large, coupled with the friction between the hydraulic oil and the tubing, we must apply a lot of strength to allow the outer kit (62) to drive the first kit (64) and the second kit (66), it is not applicable to women. Riders such as children, the elderly, etc.; in addition, the outer kit (62) does not have a marking area, so that the rider must use the trial and error method to know the effect of clockwise rotation and counterclockwise rotation. Even if there is a marked area, the marked area has to be rotated together with the outer set (62), so the conventional adjustment device still has room for improvement.

In view of the problems of the above-mentioned conventional adjustment device, the present creator further studies and develops, so the main purpose of the present invention is to provide a gap adjusting device for a disc brake block which is easy to operate and requires less effort. The secondary purpose of this creation is to provide a gap adjustment device for the disc brake pad with a prompt operation.

In order to achieve the foregoing objectives, the technical means employed in the present invention is to provide a gap adjusting device for a disc brake block, comprising: a first joint, wherein the hollow tube body is provided with an oil chamber, and The outer end of the first joint is a first connecting portion; a knob is pivotally disposed at an inner end of the first joint, and the knob is internally provided with an internal thread; and a second joint is hollow The inner end of the pipe body is set as a piston end, and the outer end is set as a second joint portion, and an intermediate thread is disposed at a middle portion thereof, and the external thread is screwed into an internal thread extending through the knob, so that the piston The end portion is inserted into the oil chamber of the first joint, and the first joint portion of the first joint is set to be an external thread.

The above-mentioned knob is pivotally disposed at the inner end of the first joint by providing a ring groove at the inner end of the first joint, and the ring groove is provided with an opposite two-way hole, and a buckle sleeve is further provided The ring is disposed in the ring, so that the two resisting portions of the buckle are sunk into the ring groove provided at the front end of the knob through the two through holes, and the buckle is set to C shape, and the knob is further An O-ring is disposed between the inner end of the first joint.

The first joint described above is provided with a marking area for the rider to view the direction in which the rotation is to reduce the gap or increase the gap.

Therefore, the use of the above technical means in accordance with the present creation has the following effects:

1. This creation only adjusts the gap of the disc brake block by rotating the knob. Because the length of the knob is relatively short, the friction between the internal thread of the knob and the external thread of the second joint is relatively reduced, and thus the stroke can be made smaller. The force to change the volume inside the oil chamber can adjust the gap of the brake block, which is suitable for riders such as women, children, the elderly and the like.

2. The creation department has a marking area in the first joint, so that the rider can watch the direction of rotation of the viewer to reduce the gap, or increase the gap, and the marking area does not rotate with the first joint to facilitate riding. Passenger operation.

First of all, please refer to the figures 1 to 4, which is a gap adjusting device 1 for a disc brake block, which is mainly installed in the oil passage between the brake grip 5 and the brake caliper 6. 7, the system includes: a first joint 20, a knob 30 and a second joint 40; wherein the first joint 20 is provided with a oil chamber 22 inside the hollow tubular body, and the first joint 20 The outer end of the second joint 40 is formed by the piston end 42 of the second joint 40 and the inner portion of the first joint 20; the first joint portion 23 is also provided. For the external thread 231, the first connecting portion 23 is connected to the brake grip or the brake caliper 6; and the first joint 20 is provided with a marking area 26 for reducing the direction in which the rider views the rotation. a gap, or a gap is added, and a ring groove 24 is disposed at an inner end of the first joint 20, and an opposite two-way hole 241 is defined in the ring groove 24; the knob 30 is pivoted on the first An inner end of a joint 20, and an internal thread 31 is disposed inside the knob 30, and the knob 30 is pivotally disposed on the inner side of the first joint The second retaining portion 25 of the retaining ring 25 is provided with a two-way hole 241 through the annular groove 24. Then, it is sunk into the ring groove 32 provided at the front end of the knob 30, so that the knob 30 is coupled to the inner end of the first joint 20, and the knob 30 can be made relative to the first connection. The head 20 is relatively rotated; in particular, an O-ring 33 is provided between the knob 30 and the inner end of the first joint 20, and the O-ring 33 has a frictional force between the knob 30 and the first joint 20. a rider who is interested in women, children, the elderly, etc., spends less effort to rotate the knob 30; and the second joint 40 is such that the inner end of the hollow tubular body is set to the piston end 42, and the piston The end 42 is assembled with a plurality of O-rings, and the outer end of the second joint 40 is defined as a second connecting portion 43 with an external thread 44 therebetween, and the external thread 44 is screwed into and engaged with The internal thread 31 of the knob 30 is such that the piston end 42 is sealed and sleeved in the oil chamber 22 of the first joint 20.

Referring to FIG. 3 and FIG. 4, the C-shaped buckle 25 is engaged in the ring groove 24 of the first joint 20 by the gap adjusting device 1 of the present invention.
