Description

Technical Field

[0001] The utility model relates to a connector, in particular to a metal air inlet and outlet connector, belonging to the technical field of air flow transportation. Background Technique

[0002] With the improvement of living standards, automobiles have become an indispensable part of life. However, while bringing convenience to life, they also add some troubles. For example, air appears in the brake hydraulic pipeline, resulting in partial failure of the braking system. For vehicle manufacturers, they usually evacuate the brake hydraulic pipeline to vacuum and then fill the pipeline with brake fluid under high pressure to exhaust all the air. However, during the use of the vehicle, when air appears in the brake pipeline, it is impossible to evacuate the pipeline to vacuum and then fill it under high pressure. Therefore, an air exhaust device for the vehicle brake pipeline is very necessary. In this system, a connector is used to meet the air flow.

[0003] For example, the utility model with the patent application number 201720300043.0 discloses an air brake connector, which includes an air inlet, an air outlet, an air inlet pipe and an air outlet cavity. The air inlet pipe includes a first air inlet part, a second air inlet part and a third air inlet part. The first air inlet part is communicated with the air inlet, the third air inlet part is communicated with the air outlet cavity, the inner wall of the first air inlet part inclines towards the axis of the air inlet pipe at a first angle from the air inlet to the air outlet cavity, and a guiding surface is provided on the second air inlet part, and the guiding surface inclines towards the axis of the air inlet pipe at a second angle from the air inlet to the air outlet cavity.

[0004] However, when the connector is applied, especially when the pipelines connected to both ends of the connector are damaged, it is necessary to disassemble them one by one for inspection to confirm the pipeline that needs to be repaired, which requires a lot of time and high maintenance costs. Content of the Utility Model

[0009] Preferably, the pipe mounting head and the change-direction mounting head are vertically distributed on the outside of the guide box, and the operating bolt is arranged on one side of the pipe mounting head. One end of the operating bolt is fixedly connected to a hexagonal column, which provides a fulcrum for the operating bolt, facilitates the operation of the operating bolt, and controls the rotation of the operating bolt.

[0010] Preferably, a group of the arc-shaped grab plates includes a plurality of arc-shaped grab plates, and the plurality of arc-shaped grab plates are all fixedly connected to the outer side of the additional rod.

[0011] Preferably, a group of the rubber bent plates includes multiple rubber bent plates, and the multiple rubber bent plates are fixedly connected to the outside of the additional rod and are staggered with the arc-shaped grab plates. After the rubber bent plates are deformed, impurities in the airflow enter the interior of the arc-shaped grab plates, and the multiple arc-shaped grab plates that cannot be deformed intercept the impurities.

[0012] Preferably, one end of the additional rod is fixedly connected to a mounting bolt, and a mounting rod is provided on one side of the mounting bolt. A mounting thread groove is provided on one side of the mounting rod. The additional rod can be disassembled by rotating the additional rod so that the mounting bolt leaves the inside of the mounting thread groove, and the additional rod can be thoroughly cleaned or replaced quickly.

[0013] Preferably, one end of the mounting rod passes through the pipe mounting head and is fixedly connected to the sliding box, and the sliding box is arranged on a side of the guide box away from the pipe mounting head.

[0014] Preferably, a joint is fixedly connected to the outside of the guide box, the pressure sensor is fixedly connected to the sliding box, and an electric wire is fixedly connected between the pressure sensor and the joint. A part of the electric wire is bent and stored inside the sliding box, so the movement of the sliding box is not affected.

[0015] The utility model provides a metal joint for air inlet and outlet, which has the following beneficial effects:

[0016] 1. For this air inlet and outlet metal joint, operating the bolt causes the sliding box, which is rotatably connected at one end, to move. Controlling the movement of the sliding box from the side of the pipeline installation head away from the inside of the diversion box towards the pipeline installation head and controlling the overlapping area between the sliding box and the side variable-direction installation head can adjust the volume of the internal connection between the variable-direction installation head and the diversion box, control the size of the airflow discharged from the inside of the variable-direction installation head, enable the metal joint to play a flow cutoff role, facilitate the maintenance of the pipelines connected to the pipeline installation head and the variable-direction installation head, and ensure the adaptability of the joint.

[0017] 2. For this air inlet and outlet metal joint, after the sliding box completely covers the variable-direction installation head, the pipeline connected to the variable-direction installation head and the pipeline connected to the pipeline installation head are then cut off. At this time, connect the joint to the equipment, and the pressure sensor is electrically connected to monitor the hydraulic pressure inside the pipeline installation head. By the change in the hydraulic pressure inside the pipeline installation head, it can be determined whether the pipeline connected to the pipeline installation head and the pipeline connected to the pipeline installation head are cracked or damaged, which can quickly determine whether the pipeline connected to the pipeline installation head or the pipeline connected to the variable-direction installation head is damaged, providing data support for the maintenance of the pipeline system.

[0018] 3. For this air inlet and outlet metal joint, the additional rod is inserted into the pipeline connected to the pipeline installation head. Since the rubber bent plate bends in the direction of the airflow, after the rubber bent plate deforms, impurities in the air enter the inside of the arc-shaped grab plate, and the multiple arc-shaped grab plates that cannot deform intercept the impurities, playing a role in intercepting and filtering large particles, cloth strips, plastics and other impurities in the airflow. When the air supply inside the pipeline connected to the pipeline installation head stops, at this time, the impurities are inside the rubber bent plate, and the flow direction of the impurities is the concave direction of the rubber bent plate. In this direction, the force required for the rubber bent plate to deform is relatively large, and at this time, the rubber bent plate cannot deform to intercept and block the impurities, preventing the impurities from flowing away with the airflow.

[0025] An embodiment of the utility model provides a gas inlet and outlet metal joint.

[0026] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , including a guide box 1, the outside of the guide box 1 is fixedly connected to a pipe mounting head 2, a change-direction mounting head 3 and a mounting nut 4, the internal thread of the mounting nut 4 is connected to an operating bolt 5, one end of the operating bolt 5 is rotatably connected to a sliding box 7, a pressure sensor 8 and an additional rod 12 are provided on one side of the sliding box 7, and a group of rubber bent plates 13 and two groups of arc-shaped grab plates 14 are fixedly provided on the outside of the additional rod 12.

[0027] When the utility model is in use: a pipe mounting head 2, a direction-changing mounting head 3 and a mounting nut 4 are fixedly connected to the outside of the guide box 1, and the axes of the pipe mounting head 2 and the direction-changing mounting head 3 distributed on the outside of the guide box 1 intersect vertically, so after the airflow enters the interior of the guide box 1 through the pipe mounting head 2, it flows out through the direction-changing mounting head 3 fixed on one side of the guide box 1. The metal joint composed of the metal guide box 1, the pipe mounting head 2, the direction-changing mounting head 3 and other structures plays a role in guiding and changing direction. By controlling the position and angle of the direction-changing mounting head 3 when it is installed on the outside of the guide box 1, the air can be changed in different directions.

[0028] When the nut 4 is in the state of being screwed, the nut 4 is screwed, and the nut 4 is in the state of being screwed. When the nut 4 is in the state of being screwed, the nut 4 is screwed, and the nut 4 is in the state of being screwed. When the nut 4 is in the state of being screwed, the nut 4 is in the state of being screwed. When the nut 4 is in the state of being screwed, the nut 4 is in the state of being screwed. When the nut 4 is in the state of being screwed, the nut 4 is in the state of being screwed. When the nut 4 is in the state of being screwed, the nut 4 is in the state of being screwed.

[0029] On one side of the sliding box 7, a pressure sensor 8 and an additional rod 12 are provided. A connector 9 is fixedly connected to the outside of the diversion box 1. A wire 10 is fixedly connected between the pressure sensor 8 fixedly connected to the sliding box 7 and the connector 9. During the movement of the sliding box 7, the sliding box 7 moves away from the outside of the connector 9 fixed to the diversion box 1, and a part of the surplus of the wire 10 is bent and stored inside the sliding box 7, so the movement of the sliding box 7 is not affected.

[0030] When the sliding box 7 completely blocks the direction-changing mounting head 3, at this time, the pipeline connected to the direction-changing mounting head 3 is cut off from the pipeline connected to the pipeline mounting head 2. At this time, the connector 9 is connected to the equipment, and the pressure sensor 8 is electrically connected to monitor the hydraulic pressure inside the pipeline mounting head 2. By the change of the hydraulic pressure inside the pipeline mounting head 2, it can be judged whether the pipeline connected to the pipeline mounting head 2 and the pipeline connected to the pipeline mounting head 2 are cracked or damaged, and it can quickly judge whether the pipeline connected to the pipeline mounting head 2 or the pipeline connected to the direction-changing mounting head 3 is damaged, providing data support for the maintenance of the pipeline system.

[0031] On the outside of the additional rod 12, a set of rubber bent plates 13 and two sets of arc-shaped grab plates 14 are fixedly arranged. Since the multiple arc-shaped grab plates 14 of a set of arc-shaped grab plates 14 are all fixedly connected to the outside of the additional rod 12, and the multiple rubber bent plates 13 included in a set of rubber bent plates 13 are all fixedly connected to the outside of the additional rod 12, the rubber bent plates 13 and the arc-shaped grab plates 14 are arranged alternately on the outside of the additional rod 12. The additional rod 12 is inserted into the pipeline connected to the pipeline mounting head 2. Since the rubber bent plates 13 are bent in the advancing direction of the air flow, after the rubber bent plates 13 are deformed, impurities in the air enter the inside of the arc-shaped grab plates 14, and the multiple arc-shaped grab plates 14 that cannot be deformed intercept the impurities, playing a role in intercepting and filtering large particles, cloth strips, plastics and other impurities in the air flow. When the air supply inside the pipeline connected to the pipeline mounting head 2 stops, at this time, the impurities are inside the rubber bent plates 13, and the flow direction of the impurities is the concave direction of the rubber bent plates 13. In this direction, the force required for the rubber bent plates 13 to deform is relatively large. At this time, the rubber bent plates 13 cannot deform to intercept and block the impurities, preventing the impurities from flowing away with the air flow and ensuring the filtering effect.

[0032] After the pipeline connected to the pipeline mounting head 2 is disassembled, the additional rod 12 is exposed, and the impurities between the arc-shaped grab plates 14 and the rubber bent plates 13 can be cleaned. One end of the additional rod 12 is fixedly connected with a mounting bolt 15, and a mounting thread groove 16 is opened on one side of the mounting rod 11 fixedly connected to the sliding box 7. By rotating the additional rod 12 to make the mounting bolt 15 leave the inside of the mounting thread groove 16, the additional rod 12 can be disassembled, and the thorough cleaning or replacement of the additional rod 12 can be completed quickly.
