Detailed Description
The technical scheme described in the application is further described and illustrated below with reference to the accompanying drawings and examples. The specific meaning of technical terms in this application may be understood by one of ordinary skill in the art based on the specific situation in combination with common general knowledge in the art, design specifications, standard documents, etc.
Example 1
As shown in fig. 1 to 5, the sealing plug capable of exhausting comprises a plug body 1, wherein the plug body 1 is provided with a plug end face 8 matched with a plug end hole and a circumferential side wall matched with a plug side wall, a plug body inner cavity 6 is processed on the bottom surface of the plug body 1, a holding part 7 integrated with the plug body 1 is arranged in the plug body inner cavity 6, and the holding part 7 extends in a direction away from the plug end face 8; the plug body 1 is further provided with a compression exhaust pipe 2 at the plug end face 8, and the compression exhaust pipe 2 extends for a certain distance in a direction away from the plug end face 8, and the distance is suitable for meeting assembly requirements. The bottom or circumferential side wall of the plug 9 is machined with a flat surface which mates with the compressed exhaust pipe 2.
The compression exhaust pipe 2 and the plug body 1 form a whole, ventilation holes 3 penetrating the compression exhaust pipe 2 and the plug body 1 are formed in the compression exhaust pipe 2 and the plug body 1, the ventilation holes 3 comprise two parts, one part is a circular through hole part 4 positioned in the compression exhaust pipe 2, and the other part is a conical hole part 5 positioned in the plug body 1.
The plug body 1, the compressed exhaust pipe 2 and the holding part 7 are made of elastomer materials, and the elastomer materials can be obviously deformed when being subjected to external force and can quickly recover to be close to the polymer materials in the original state and size after the external force disappears, such as non-metal elastic materials like rubber materials and silica gel materials. When the plug end face 8 contacts with the plug end face, the compressed exhaust pipe 2 can be similarly extruded from the plug end face to deviate to one side, and along with the continuous approach of the plug end face 8 in the plug body 1 and the plug end hole end face, the circular through hole part 4 in the compressed exhaust pipe 2 is elastically deformed and gradually closed in the process of extrusion of the corresponding planes in the compressed exhaust pipe 2 and the plug 9.
The gripping portion 7 described in the present application can facilitate the operator to insert the plug body 1 into the connector and take out the plug body 1 from the connector.
On the basis of the above embodiments, the technical features involved therein and the functions and roles that the technical features play in the technical solution are described in detail using the following paragraphs so as to help those skilled in the art to fully understand the technical solution and reproduce it.
Referring to fig. 1 to 3, the plug body 1 and the plug 9 to be plugged and sealed have the same cross-sectional shape, and the outer diameter of the plug body 1 is larger than the inner diameter of an end hole (plug hole) of the plug end of the plug 9, so that the plug body 1 is elastically deformed by being extruded by the inner wall of the plug 9 when being inserted into the plug 9.
The plug body 1 is provided with a plug body inner cavity 6 for enhancing the elastic deformation of the plug body, and the plug body inner cavity 6 can facilitate the plug body 1 to be inserted into the plug connector 9 and can increase the deformation of the plug body 1.
Meanwhile, in order to improve the plugging convenience and operability of the plug body 1, a holding part 7 integrated with the plug body 1 is further arranged in the inner cavity 6 of the plug body, and the holding part 7 extends a certain distance away from the plug body 1. The operator inserts and separates the plug body 1 into and from the plug 9 through the grip portion 7.
The plug body 1 is provided with a compression exhaust pipe 2 with the end surface higher than the plug end surface 8 at the plug end surface 8 matched with the plug 9, the compression exhaust pipe 2 and the plug body 1 are integrally arranged, and a circular through hole part 4 penetrating through the compression exhaust pipe 2 is arranged in the compression exhaust pipe 2; the plug body 1 is provided with a tapered hole 5 at a position corresponding to the compressed exhaust pipe 2, and the tapered hole 5 is communicated with the circular through hole 4. When the plug body 1 and the plug 9 are plugged into place, as shown in fig. 4 and 5, the compressed exhaust pipe 2 is offset to one side of the plug body 1 and gradually matched with the step structure inside the plug to be flattened along with the approach of the plug end surface 8 and the inner end surface of the plug 9, and the flattened compressed exhaust pipe 2 can seal the circular through hole 4 inside the compressed exhaust pipe. At the same time, the plug body 1 is extruded by the side wall of the connector 9 to generate elastic deformation, so that the conical hole part 5 in the plug body 1 is extruded to be closed. Namely, in the process of inserting the plug body 1 into the plug 9, the air holes 3 can enable air in the plug 9 to be discharged, and as the plug body 1 and the compression exhaust pipe 2 are inserted deeply, the extrusion deformation acting force applied to the plug body 1 and the compression exhaust pipe 2 is increased, and the air holes 3 are closed due to the extrusion deformation of the plug body 1 and the compression exhaust pipe 2, so that the functions of dust prevention and water prevention are achieved.
Finally, although the description has been described in terms of embodiments, not every embodiment is intended to include only a single embodiment, and such description is for clarity only, as one skilled in the art will recognize that the embodiments of the disclosure may be combined as appropriate to form other embodiments that will be apparent to those skilled in the art.
