Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connectors, in particular to a quick-install vacuum pipeline connector. Background Art

[0002] Some pipelines or cavities need to be in a negative pressure state, so the pipelines or cavities need to be evacuated. The vacuum pump evacuates them through the pipeline connector. When the vacuum degree inside the pipeline or cavity reaches the requirement, the vacuum device needs to be removed. Before removing the vacuum device, the pipeline or cavity needs to be sealed.

[0003] However, some current pipeline connectors are not convenient for sealing pipelines or cavities when in use, and when the vacuum device is disassembled, the vacuum pipeline may no longer be in a vacuum state; therefore, they do not meet existing needs. We have proposed a quick-install vacuum pipeline connector. Utility Model Content

[0006] Preferably, the exhaust pipe is connected to the connector body through a vertical pipe, and a flange connector is sleeved on the upper part of the outer surface of the exhaust pipe.

[0007] Preferably, the inner wall of the fixing ring is fixedly connected to the outer surface of the connector body, the threaded hole is connected to the threaded rod through threads, and the threaded rod is rotatably connected to the outer surface of the arc-shaped clamping plate through a bearing.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model provides a limited position mechanism. When the pipe is inserted into the inner side of the connector body, the threaded rod can be rotated so that the threaded rod can move inside the threaded hole, driving the arc-shaped clamping plate to move toward the outer surface of the pipe until the outer surface of the arc-shaped clamping plate is closely attached to the outer surface of the pipe, thereby stably clamping the pipe. The rubber pad is provided to improve the stability of pipe clamping and the stability of pipe vacuum treatment.

[0013] 2. The utility model is provided with a sealing mechanism and an L-shaped push rod. When the pipe is inserted into the inner side of the connector body, the L-shaped push rod will push the sealing column away from the limit ring. The sealing column leaves the inner side of the limit ring, and the gas can be extracted through the gap between the sealing column and the limit ring. When the vacuum treatment is completed, the pipe is taken out of the connector body. Without the thrust of the L-shaped push rod, the sealing column returns to the initial position under the action of the spring and is stuck in the inner side of the limit ring to seal the pipe. The utility model is provided with a sealing mechanism, so the pipe can be sealed in time, thereby ensuring the vacuum state inside it. BRIEF DESCRIPTION OF THE DRAWINGS
