Tubing with quick connector

The present invention relates to a pipe joint or a pipe fitting, in particular to a fuel pipe having a quick joint which is convenient and quick to install and can reduce the influence of air in the pipeline.

The oil pipe is generally used as a part of a hydraulic transmission device and is generally used in daily life. The hydraulic transmission device that most commonly uses the oil pipe in life is the hydraulic brake of the bicycle. Due to the consideration of portability and safety, the hydraulic brake has been in recent years. Widely deployed on bicycles to replace the original cable-type brakes, hydraulic brakes are filled with hydraulic oil inside the tubing as a medium for power transmission; in order to avoid the inconvenience caused by refilling hydraulic oil after completion of piping, the existing tubing system Prior to installation, the hydraulic oil is filled inside the tubing and sealed with a seal, so that the user can remove the seal and connect the tubing after the tubing is completed.

As shown in FIG. 6, FIG. 7A and FIG. 7B, a conventional oil pipe comprises: a pipe body 60, a first joint 70, a sealing member 80 and a second joint 90; wherein the pipe body 60 has opposite ends, The first joint 70 is disposed at one end of the tubular body 60 and has an end surface away from the tubular body 60. The first joint 70 includes a passage 71 and a sealing screw hole 72. The passage 71 is disposed through the first joint 70, and the sealing member The screw hole 72 is recessed in the end surface of the first joint 70 and communicates with the passage 71. The seal screw hole 72 is provided with a thread for screwing on the inner circumferential surface, and the sealing member 80 includes a screw lock portion 81 and a screw lock portion. The circumferential surface of 81 is provided with a thread for screwing, and the sealing member 80 is locked to the sealing screw hole 72 of the first joint 70 by the screwing portion 81 provided to seal the passage 71, thereby avoiding the hydraulic oil encapsulated in the oil pipe. The second joint 90 is disposed at the other end of the tubular body 60.

Although the existing oil pipe can prevent the leakage of the hydraulic oil by the sealing member 80, after the oil pipe is disposed, the sealing member 80 needs to be screwed out of the sealing screw hole 72 of the first joint 70, which is inconvenient and time consuming to use. In addition, after the sealing member 80 is separated from the first joint 70, the seal screw hole 72 of the first joint 70 is filled with air, so that after the tubing is installed, the air in the seal screw hole 72 may be interposed between the hydraulic oil. Between, because the air is compressible, it will affect the transmission of power and reduce the sensitivity of the hydraulic transmission.

In order to solve the problem that the existing oil pipe is inconvenient to install due to the screwing method of the sealing member and the air in the pipeline is easy to intervene, the power supply is not good, and the present invention proposes a fuel pipe with a quick joint and an integral connection. The sealing member of the joint body allows the user to connect the pipeline by breaking the seal after the oil pipe is disposed, so as to achieve the purpose of convenient and quick installation, and can avoid the intervention of air in the oil pipe and affect the sensitivity of the hydraulic device. .

The oil pipe having a quick joint, wherein the connecting portion has a conical shape and has a first joint end opposite to the second joint end, and the first joint end of the joint portion is connected to the seal portion And the outer diameter of the second joint end is smaller than the outer diameter of the first joint end.

The oil pipe having a quick joint, wherein the stopper is spherical.

The oil pipe having a quick joint, wherein the groove has a slope which is annular.

The enhancements obtained by the technical means of the creation are as follows: 1. The oil pipe with the quick joint of the present invention can continue to fix the quick joint as long as the seal is broken and the seal is separated from the joint body, compared with the existing oil pipe. Underneath, this creation eliminates the need to unscrew the seal and saves time. 2. The groove provided in the stop head of the joint body can avoid the burr generated when the seal is broken, and interfere with other components when the joint body and other hydraulic operating structures are consolidated, thereby affecting the degree of adhesion. 3. The creation may further include a ball-shaped stopper, and a seal groove communicating with the passage is further disposed in the seal of the quick joint, and the user can inject the hydraulic oil from the quick joint into the pipe body through the cavity Then, the stopper is inserted into the tank to encapsulate the hydraulic oil. 4. The second joint end of the joint of the present invention has a wall thickness of between 0.1 mm and 1 mm to facilitate the user to break the seal by hand.
