Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a high-seal automobile plug. Background Art

[0002] The sealing plug is a common automotive part, usually made of rubber, and is mainly used for sealing. The existing sealing plug is designed with a smaller diameter at the insertion end, which then gradually increases to form a truncated cone shape. When inserted into a hole, the truncated cone part will rub against the hole. After repeated insertion and removal friction, this part of the rubber is easily worn, resulting in a reduction in diameter and a decrease in sealing performance. Therefore, a high-sealing automotive plug is needed to extend the service life of the plug while ensuring sealing and facilitating insertion and removal. Utility Model Content

[0003] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0004] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide a high-sealing automobile plug, including a base, a mounting mechanism fixed on the base, and a sealing mechanism fixed on the base; the sealing mechanism includes a sealing plug fixed on the base, a pneumatic assembly fixed on the sealing plug, and a support ring fixed on the sealing plug. The base is made of plastic material and is disc-shaped; the mounting mechanism is used to install the plug; the sealing mechanism is used for sealing, and cooperates with the mounting mechanism to enhance the sealing effect and achieve high sealing; the sealing plug is made of rubber material, and the sealing plug is truncated cone-shaped, with a smaller diameter at the lower end and a larger diameter at the upper end. After being inserted into the hole, the upper end can block the hole and play a preliminary sealing effect; the pneumatic assembly cooperates with the mounting mechanism to enhance the sealing effect; the support ring is vertically arranged, and the support ring is at a certain distance from the upper end of the sealing plug truncated cone. When the plug is inserted into the hole, the upper end of the sealing plug contacts the lower end surface of the hole, and the support ring contacts the upper end surface of the hole, that is, the sealing plug and the support ring clamp the part where the hole is located, and the support ring plays a role in supporting the plug, so that the sealing plug is not easy to slide up and down.

[0005] Specifically, the mounting mechanism includes a mounting column fixed on the base, a slide groove fixed on the mounting column, a pressing plate slidably mounted on the slide groove, a connecting column fixed on the pressing plate, and a handle fixed on the connecting column. The portion where the mounting column contacts the connecting column is provided with threads; the space formed by the lower end surface of the pressing plate and the base and the pneumatic assembly is a closed space; the connecting column is provided with threads; the handle is convenient for the user to rotate; in the initial state, the pressing plate is located at the uppermost end of the slide groove.

[0006] Specifically, the pneumatic assembly includes a cavity fixed on the sealing plug, and an air groove fixed on the sealing plug and the base. In the initial state, there is no gas in the cavity, and the gas is located in the space formed by the lower end of the pressure plate and the base. Since the space formed by the lower end surface of the pressure plate, the base and the pneumatic assembly is a closed space, the cavity will be squeezed by the external air pressure, causing the sealing plug in this part of the cavity to shrink and reduce its diameter. In this way, when inserting the hole, the sealing plug is not easy to rub against the edge of the hole, which is convenient for inserting the hole, while also reducing wear and extending the service life of the plug; when the sealing plug is inserted, the handle is rotated to move the pressure plate downward, and the air under the pressure plate enters the cavity through the air groove, causing the sealing plug near the cavity to expand, thereby enhancing the sealing effect. At the same time, after the sealing plug expands, the upper end of the sealing plug contacts the lower end surface of the hole, and the support ring contacts the upper end surface of the hole, that is, the sealing plug and the support ring clamp the parts where the hole is located so that the sealing plug is not easy to slide up and down.

[0007] The beneficial effects of the utility model are:

[0008] (1) It is equipped with a pneumatic assembly and an installation assembly, which can reduce the diameter of part of the sealing plug during installation, making it easier to insert into the hole, while also reducing wear and extending the service life of the plug.

[0009] (2) A support ring is provided. When the plug is inserted into the hole, the upper end of the sealing plug contacts the lower end surface of the hole, and the support ring contacts the upper end surface of the hole, that is, the sealing plug and the support ring clamp the part where the hole is located, and the support ring plays a role in supporting the plug.

[0010] (3) After the sealing plug is inserted, the handle is rotated to move the pressure plate downward. The air below the pressure plate enters the cavity through the air groove, causing the sealing plug near the cavity to expand, thereby enhancing the sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0022] Reference Figure 1-3 As shown, a high-sealing automobile plug described in the utility model includes a base 1, a mounting mechanism 2 fixed on the base, and a sealing mechanism 3 fixed on the base; the sealing mechanism includes a sealing plug 31 fixed on the base, a pneumatic component 32 fixed on the sealing plug, and a support ring 33 fixed on the sealing plug.

[0023] Specifically, the installation mechanism includes a mounting column 21 fixed on the base, a slide groove 22 fixed on the mounting column, a pressure plate 23 slidably arranged on the slide groove, a connecting column 24 fixed on the pressure plate, and a handle 25 fixed on the connecting column.

[0024] Specifically, the pneumatic assembly includes a cavity 321 fixedly arranged on the sealing plug, and an air groove 322 fixedly arranged on the sealing plug and the base.

[0025] In the initial state, the pressure plate is located at the uppermost end of the slide groove, and there is no gas in the cavity. The gas is located in the space formed by the lower end of the pressure plate and the base. Since the space formed by the lower end surface of the pressure plate, the base and the air pressure component is a closed space, the cavity will be squeezed by the external air pressure at this time, causing the sealing plug in this part of the cavity to shrink and reduce its diameter; when in use, the sealing plug is partially inserted into the hole. Since the diameter of part of the sealing plug is reduced, it is not easy to rub against the edge of the hole when inserted into the hole, which is convenient for insertion into the hole, while also reducing wear and extending the service life of the plug. Then rotate the handle to move the pressure plate downward, and the air under the pressure plate enters the cavity through the air groove, causing the sealing plug near the cavity to expand, thereby enhancing the sealing effect. At the same time, after the sealing plug expands, the upper end of the sealing plug contacts the lower end surface of the hole, and the support ring contacts the upper end surface of the hole, that is, the sealing plug and the support ring clamp the part where the hole is located, so that the sealing plug is not easy to slide up and down.
