Description

Technical Field

[0001] The utility model relates to the technical field of brake lines, in particular to a brake line which can be replaced conveniently. Background Art

[0002] The brake line structure is used in the vehicle braking system and involves pipes, lines or transmission systems. It plays the role of transmitting the braking force from the operating components to the actual braking components. The brake line structure effectively slows down or stops the vehicle by transmitting the braking operating force. It is a key component of vehicle safety. Well-designed brake lines can improve vehicle safety and reduce the possibility of accidents.

[0003] With the existing brake cable structure, there is a bulge in the middle of the front and rear joints of the brake cable when replacing it. The brake cable is bound by a cable tie and is difficult to pull through. If too much force is used, the cable tie may break and other connecting wires may be broken at the same time. Therefore, the vehicle plastic shell can only be removed before replacing the brake cable. After replacing the brake cable, the shell can be installed. This operation is time-consuming and laborious.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 - Figure 5 , a conveniently replaceable brake line comprises a jacket 1 and a wire core 2, the wire core 2 runs through the inside of the jacket 1, and connecting rings 4 are fixedly installed at both ends of the jacket 1, and an externally threaded tube 5 is provided on the connecting ring 4, and a No. 1 nut 6 is threadedly connected to the externally threaded tube 5, and a notch is provided on the No. 1 nut 6 and the bushing 7, and the No. 1 nut 6 is threadedly connected to the externally threaded tube 5 to play the role of a gate. When using the conveniently replaceable brake line, after the jacket 1 is set on the vehicle, the two ends of the wire core 2 are respectively connected to the brake mechanism and the brake handle on the vehicle, and the wire core 2 can be driven to move by moving the brake handle through the zinc head 3, and then the brake mechanism can be driven to move to brake the vehicle. When the wire core 2 is broken and the brake line is replaced as a whole, the No. 1 nut 6 is rotated to separate the No. 1 nut 6 from the externally threaded tube 5, and the No. 1 nut 6 can be removed through the notch on the No. 1 nut 6. It is removed from the wire core 2, and the same is true for the bushing 7. Then, the old brake line is fixedly connected to the new brake line using a connecting tool. Then, the brake line can be pulled to pull the replaced brake line into the vehicle, and the brake line can be quickly replaced. Since the No. 1 nut 6 is removed, the brake line will not be blocked by the gate when it is replaced, which makes it easy to replace the brake line, thereby achieving the purpose of facilitating the replacement of the brake line and avoiding the brake line being stuck in the vehicle due to the protrusion of the gate when replacing the brake line, and the need to remove the plastic shell of the vehicle is required, thereby improving the practicality of the convenient replacement of the brake line. After the new brake line is replaced, the No. 1 nut 6 is sleeved on the wire core 2 through the set notch, and then the No. 1 nut 6 is threadedly connected to the external threaded tube 5, and then the No. 1 nut 6 is moved to a predetermined position to play the role of a gate.

[0023] See also Figure 1 The wire core 2 passes through the external threaded barrel 5, and the external threaded barrel 5 is used for threaded connection with the No. 1 nut 6.

[0024] See also Figure 1 One end of the wire core 2 is fixedly connected with a zinc head 3, and the zinc head 3 is used to limit the wire core 2 to prevent the wire core 2 from completely entering the jacket 1. At the same time, the zinc head 3 facilitates the connection between the wire core 2 and the brake handle.

[0025] See also Figure 3 , Figure 4 and Figure 5A bushing 7 is provided on the externally threaded tube 5, and the wire core 2 passes through the inside of the bushing 7. When the conveniently replaced brake line is installed and used, the bushing 7 is used to protect the threads of the externally threaded tube 5 close to the brake handle to avoid wear of the surface threads caused by friction between the externally threaded tube 5 and the brake handle, thereby improving the protection performance. A screw rod 8 is connected to the other end of the wire core 2, and a reset spring 9 is installed around the screw 8. The reset of the reset spring 9 will push the screw rod 8 to reset, and then the wire core 2 will be driven to reset when the screw 8 moves. A cross pin 10 is fixed on the screw 8, and a No. 2 nut 11 is fixedly connected to one end of the screw 8.

[0026] Working principle: first, when using the conveniently replaced brake line, after setting the outer sleeve 1 on the vehicle, connect the two ends of the line core 2 to the brake mechanism and the brake handle on the vehicle respectively, and then move the brake handle through the zinc head 3 to drive the line core 2 to move, and then drive the brake mechanism to brake the vehicle. When the line core 2 breaks, the brake line is replaced as a whole. Turn the No. 1 nut 6 to separate the No. 1 nut 6 from the external threaded tube 5. After the old brake line is connected to the new brake line, the No. 1 nut 6 can be removed from the line core 2 through the notch on the No. 1 nut 6. The same is true for the bushing 7. Then use the connecting tool to fix the old brake line with the new brake line, and then pull the brake line to pull. The brake line to be replaced automatically enters the interior of the vehicle, and then the brake line can be quickly replaced. Since the No. 1 nut 6 is removed, it will not be blocked by the gate when replacing the brake line, which makes it easy to replace the brake line, thereby achieving the purpose of facilitating the replacement of the brake line and avoiding the brake line being stuck in the vehicle due to the protrusion of the gate when replacing the brake line, and the need to remove the plastic shell of the vehicle is required, thereby improving the practicality of the convenient replacement of the brake line. After the new brake line is replaced, the No. 1 nut 6 is sleeved on the wire core 2 through the set notch, and then the No. 1 nut 6 is threadedly connected with the external threaded tube 5, and then the No. 1 nut 6 is moved to a predetermined position to play the role of a gate.
