[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] Example 1: A high-performance vacuum brake hose assembly, such as Figure 1-Figure 4 As shown, it includes an internal hose 1 and an outer reinforcement tube 2 installed on the outside of the internal hose 1. Positioning rings 3 are provided on both opposite sides of the outer reinforcement tube 2. The positioning ring 3 is installed on the outside of the internal hose 1, and the outer reinforcement tube 2 is sleeved on the outside of the internal hose 1. An anti-backflow disk 4 is rotatably installed inside one side of the internal hose 1. There are at least two anti-backflow disks 4, and the rotation directions of the two anti-backflow disks 4 are consistent. An auxiliary pipe 7 is installed on the side of the internal hose 1. The auxiliary pipe 7 is connected to the inside of the internal hose 1, and the two anti-backflow disks 4 are located in the middle of one side of the auxiliary pipe 7.

[0026] When the device is in use, the braking air pressure or hydraulic pressure first flows to the two anti-backflow discs 4 through one side of the internal hose 1. Based on the fact that the two anti-backflow discs 4 rotate in the same direction, when they are under pressure, they will rotate to one side and open, so that the braking force is transmitted to one side, and then the guide of the rear end internal hose 1 is used to flow, so as to achieve the effect of guiding and supporting the circulation of the braking force. When the braking force circulates, under the protection limit of the outer reinforcement tube 2 on the internal hose 1, the pressure resistance of the inner wall support of the internal hose 1 is improved, and its performance during support use is improved. And under the simultaneous guidance of the auxiliary pipe 7 on one side, when the braking force impacts the anti-backflow disc 4 to open, part of the braking force is guided to flow through the auxiliary pipe 7. Based on the fact that the two anti-backflow discs 4 are in the middle of the auxiliary pipe 7, when part of the airflow flows out from the other end of the auxiliary pipe 7, the second The space between the anti-backflow disc 4 and the flow of the brake material is affected by the pressure during its circulation, driving the airflow on one side of the anti-backflow disc 4 to follow the flow, thereby causing the air on one side of the anti-backflow disc 4 to flow, reducing the resistance when the anti-backflow disc 4 rotates, and improving the smoothness of the two anti-backflow discs 4 when rotating. When the braking is completed, the two anti-backflow discs 4 can be reset at the same time under the action of their own gravity and the limited contact of the brake material. Then, under the isolation effect of the two anti-backflow discs 4, a part of the brake material is isolated between the two anti-backflow discs 4. When the brake is used next time, direct power support can be performed to achieve the effect of energy storage after the braking is completed, so as to improve the speed and performance during the next braking, and ensure the normal stability of the device during braking through the auxiliary diversion of the auxiliary pipe 7.

[0027] like Figure 1-Figure 4 As shown, the inner wall of the outer reinforcement tube 2 is in close contact with the outer side of the inner hose 1 , and the positioning rings 3 on both sides are used to limit the outer reinforcement tube 2 .

[0028] Under the protection and support of the inner hose 1 by the outer reinforcing tube 2, the supporting performance of the inner hose 1 itself improves the supporting strength of the device for the circulating material, thereby improving the supporting performance of the entire device.

[0029] like Figure 1-Figure 4 As shown, a rotating rod 5 is installed on the upper half of the side of the anti-backflow disc 4. The rotating rod 5 is installed on opposite sides of the anti-backflow disc 4, and the anti-backflow disc 4 is rotatably installed on the inner wall of the internal hose 1.

[0030] A limit baffle 6 is provided on the outer side of the lower half of the anti-backflow disc 4 . The limit baffle 6 is used to limit the rotation of the anti-backflow disc 4 . The anti-backflow disc 4 is installed on the inner wall of the internal hose 1 .

[0031] Under the rotation support of the rotating rod 5, the stability of the rotation angle and distance of the two anti-backflow discs 4 is guaranteed. At the same time, under the limitation of the limiting baffle 6 on one side, backflow can be effectively prevented, and the stability and accuracy of the two anti-backflow discs 4 when storing energy can be improved.

[0032] Example 2: A high performance vacuum brake hose assembly, such as Figure 1-Figure 4 As shown, a feed port 8 and a discharge port 9 are respectively provided at opposite ends of the auxiliary pipe 7. The feed port 8 is used for feeding, and the discharge port 9 is used for discharging. Two anti-backflow disks 4 are located between the feed port 8 and the discharge port 9.

[0033] Under the guidance of the auxiliary pipe 7 and the discharge port 9, the diversity of the brake material is ensured during its flow, and a guiding and auxiliary effect is played for the flow of the brake material, ensuring its safe and stable flow.

[0034] like Figure 1-Figure 4 As shown, a reinforcement block 10 is installed on the outside of the auxiliary pipe 7 , and the reinforcement block 10 is installed on the outside of the inner hose 1 .

[0035] A limiting ring 11 is installed at one end of the inner hose 1 close to the reinforcement block 10 , and the limiting ring 11 is used for limiting the connection of the device.

[0036] Under the protection of the reinforcement block 10, the supporting capacity of the auxiliary pipe 7 itself is improved, and the supporting effect of the auxiliary pipe 7 itself is further improved. Under the limitation of the limiting ring 11, the position of the connection can be limited to ensure the stability and reliability of the overall use of the device.

[0037] Working principle: when braking, first the brake air pressure or hydraulic pressure flows to the two anti-backflow discs 4 through one side of the internal hose 1. Based on the fact that the two anti-backflow discs 4 rotate in the same direction, when they are under pressure, they will rotate to one side and open, so that the braking force is transmitted to one side, and then the guide of the rear end internal hose 1 is used to flow, so as to achieve the effect of guiding and supporting the circulation of the braking force. When the braking force circulates, under the protection and limitation of the outer reinforcement tube 2 on the internal hose 1, the pressure resistance of the inner wall support of the internal hose 1 is improved, and its performance during support use is improved. And under the simultaneous guidance of the auxiliary pipe 7 on one side, when the braking force impacts the anti-backflow disc 4 to open, part of the braking force is guided to flow through the auxiliary pipe 7. Based on the fact that the two anti-backflow discs 4 are in the middle of the auxiliary pipe 7, when part of the airflow flows out from the other end of the auxiliary pipe 7, the second The space between the two anti-backflow discs 4 and the flow of the brake material is affected by the pressure during its circulation, driving the airflow on one side of the anti-backflow disc 4 to follow the flow, thereby causing the air on one side of the anti-backflow disc 4 to flow, reducing the resistance when the anti-backflow disc 4 rotates, and improving the smoothness of the two anti-backflow discs 4 when rotating. When the braking is completed, the two anti-backflow discs 4 can be reset at the same time under the action of their own gravity and the limited contact of the brake material. Then, under the isolation effect of the two anti-backflow discs 4, a part of the brake material is isolated between the two anti-backflow discs 4. When the brake is used next time, direct power support can be performed to achieve the effect of energy storage after the braking is completed, so as to improve the speed and performance during the next braking, and ensure the normal stability of the device during braking with the auxiliary diversion of the auxiliary pipe 7.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
