Detailed Description

To further clarify the objects, advantages and features of the present utility model, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.

In the description of the present utility model, the terms "first," "second," and the like, are added for convenience of description and reference, and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining a qualifier such as "first," "second," etc. may explicitly or implicitly include one or more such feature.

As shown in fig. 2, the present embodiment provides a joint including a clip 11, a first joint 12, a seal ring 13, and a second joint 14; the clamping band 11 is used for clamping the first joint 12 and the second joint 14; the first joint 12 is provided with a groove for placing the sealing ring 13 and a first through hole 121 for conveying materials, and the groove is arranged around the first through hole 121; the second joint 14 is provided with a second through hole 141 for conveying materials; the surface of the first joint 12 matched with the second joint 14 is a plane except the groove; when the first connector 12 and the second connector 14 are assembled together, the first through hole 121 is communicated with the second through hole 141, and the first connector 12 and the second connector 14 clamp the sealing ring 13. Wherein the material may be a gas or a liquid. The joint may be referred to as a vacuum and positive pressure resistant joint. The clamp 11 is openable and lockable, and when the clamp 11 is opened, the clamp 11 is separable from the first joint 12 and the second joint 14; when the clamp 11 is locked, the clamp 11 can clamp the first joint 12 and the second joint 14

In the joint provided in this embodiment, the sealing ring 13 is installed in the groove and is clamped by the first joint 12 and the second joint 14, and when the first through hole 121 and the second through hole 141 are in negative pressure or positive pressure, the sealing ring 13 is fixed in position and is not stretched or damaged, so that the joint is suitable for negative pressure occasions and positive pressure occasions. The surfaces of the first joint 12 and the second joint 14 are flat except the grooves, so that the processing is convenient, and the sealing ring 13 is not damaged during assembly.

Alternatively, as shown in fig. 2, the first connector 12 has the same structure as the second connector 14 except for the grooves. This facilitates the design and machining of the first joint 12 and the second joint 14. In other embodiments, the structure of the first connector 12 other than the grooves may be different from the structure of the second connector 14.

Alternatively, as shown in fig. 2, the surfaces of the first connector 12 and the second connector 14, which are matched with the clip 11, are inclined surfaces, and the thickness of the clamping portion of the first connector 12 and the second connector 14, which is clamped by the clip 11, gradually decreases in a direction away from the first through hole 121.
