Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
See fig. 1 and 2;
the first embodiment is as follows: as shown in fig. 1 and fig. 2, an embodiment of a sealed plug comprises a front half cylinder 1 and a rear half cylinder 2 which are integrally formed, wherein the front half cylinder 1 is used for butting a breathing pipe fitting installed in an automobile part and needs to be sealed, the rear half cylinder 2 is used for connecting a cylinder, based on the embodiment, the diameter and the length of the front half cylinder 1 are both larger than those of the rear half cylinder 2, the central axes of the front half cylinder 1 and the rear half cylinder 2 are in the same straight line so as to ensure that the plug is stably stressed and does not deflect in front-rear butting.
Specifically, the front half cylinder 1 is provided with an open sealing tube cavity 11, the bottom of the sealing tube cavity 11 is filled with an elastic sealing element 13, and the side surface of the elastic sealing element 13 is tightly attached to the side wall of the sealing tube cavity 11. The elastic sealing element 13 is a cake-shaped cushion block matched with the sealing tube cavity 11, specifically a polyurethane sealing block, and can provide a certain compression amount when corresponding to the respiratory tube pressed in due to the self-deformable characteristic.
Furthermore, the edge of the upper surface of the elastic sealing element 13 is provided with a circle of raised part, the raised part and the elastic sealing element 13 are arranged concentrically, the outer side surface of the raised part is tightly attached to the side wall of the sealing tube cavity 11, the rest middle part of the upper surface of the elastic sealing element 13 is a plane, and compared with the plane of the middle part, the raised part can be more tightly attached to the end surface of the breathing tube pressed into the sealing tube cavity 11, which is equivalent to secondary sealing, and the sealing effect is improved.
The portion has a ridge height of 0.1mm with respect to the remaining middle portion of the upper surface of the elastic seal member 13. The thickness of the elastic sealing member 13 is 1mm, and the thickness here does not include the height of the raised portion, that is, the thickness of the upper surface of the elastic sealing member 13 is much larger than the thickness between the plane of the raised portion and the bottom surface thereof.
In addition, the edge of the upper opening 12 of the sealing tube cavity 11 is rounded, and the edge of the upper opening 12 is covered with a sealing ring.
The rear semi-cylinder 2 is provided with an open-ended plugging tube cavity 21, is connected with the cylinder and is used for plugging, and the bottom of the plugging tube cavity 21 is a conical groove bottom 22, so that the butt joint is simpler, more accurate and stable in matching.
