Description

Technical Field

[0001] The utility model belongs to the technical field of automobile manufacturing, and in particular relates to a novel detachable blocking cover. Background Art

[0002] Currently, most off-road vehicle plugs are hot-melt plugs or ordinary sealed plugs. Off-road vehicles generally operate in harsh conditions, and wading is common. Even if a small amount of water enters the cab, it will not drain out immediately. When designing off-road vehicles, OEMs often use hot-melt adhesive to seal the floor plugs. Or, to prevent the use of the floor holes for drainage when a small amount of water enters the cab, ordinary plugs are used. However, after repeated removal, the sealing performance of ordinary plugs will weaken with the increase in insertion and removal. Improper operation will be time-consuming and labor-intensive, and may even damage the plugs, affecting the sealing performance. Because the sealing performance of the plug is inversely proportional to the ease of insertion and removal, and the outside world and the cab are separated only by the floor sheet metal, when a small amount of water squeezes into the vehicle body, the buffer space between the plug and the floor is only the thickness of the floor material. Therefore, the priority is generally to focus on sealing, and the radial or Z-direction snap-in amount of the plug is selected to be much larger than the sheet metal aperture to enhance the sealing performance. The better the sealing performance of the plugging cover, the more difficult it will be to plug and unplug, and too many times will easily damage the sealing performance and service life of the plugging cover. Utility Model Content

[0003] The technical problem to be solved by the utility model is: to overcome the deficiencies of the existing technology and provide a new type of detachable plugging cover, which can take into account both sealing and ease of insertion and removal, and a small amount of water can be discharged in a short time after entering, thereby reducing the long-term immersion time in the car.

[0004] The described novel detachable plugging cover includes a receiving plugging cover and a drainage plugging cover. The receiving plugging cover reduces its radius in a stepped manner from one end to the other end, and is successively an upper end face, a sheet metal clamping face, and a lower end face, and a through cavity extending from the upper end face to the lower end face is provided in the receiving plugging cover; wherein, the through cavity is provided with a plurality of clamping grooves at the edge of the lower end face; the drainage plugging cover is composed of a limiting plate, a blocking column, and a clamping end, which are sequentially embedded from one side of the upper end face, and the clamping end protrudes along the clamping groove to the outside of the through cavity and abuts against one side of the lower end face.

[0005] Preferably, a plurality of fixing protrusions are provided on a side of the lower end surface facing away from the sheet metal clamping surface, and the fixing protrusions are adjacent to the clamping grooves.

[0006] Preferably, a collapse groove communicating with the through cavity is provided between the sheet metal snap-fit surface and the lower end surface.

[0007] Preferably, parallel clamping plates are provided on the side walls of the clamping ends.

[0008] Preferably, a fixing groove adapted to the fixed synapse is provided on the side of the clamping plate facing the blocking column.

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] The directional terms used in the detailed description are intended solely to facilitate understanding of the technical solutions described herein by those skilled in the art based on the visual orientation shown in the accompanying drawings. Unless otherwise specified or limited, the terms "dispose," "install," and "connect" are to be interpreted broadly, and those skilled in the art will understand their specific meanings in this utility model based on the specific circumstances.

[0022] like Figures 1 to 5As shown, a new type of detachable plugging cover includes a receiving plugging cover 100 and a drainage plugging cover 200, wherein the receiving plugging cover 100 has a radius that decreases in a step-by-step manner from one end to the other end, which is an upper end face 101, a sheet metal snap-fitting face 102, and a lower end face 103, and a through cavity 104 extending from the upper end face 101 to the lower end face 103 is provided in the receiving plugging cover 100; wherein, the through cavity 104 is provided with a plurality of snap-fitting grooves 105 at the edge of the lower end face 103; the drainage plugging cover 200 is composed of a limiting plate 201, a blocking column 202, and a snap-fitting end 203, which are embedded in one side of the upper end face 101 in sequence, and the snap-fitting end 203 protrudes out of the through cavity 104 along the snap-fitting groove 105, and abuts against one side of the lower end face 103. In this way, the diameters of the upper end face 101, the sheet metal engaging face 102, and the lower end face 103 of the receiving cover 100 decrease in sequence, so that the diameter of the upper end face 101 is larger than the diameter of the hole in the sheet metal part, thereby achieving the purpose of limiting the position and preventing the receiving cover 100 from being over-embedded and falling out. At the same time, the hot-melt connection between the sheet metal engaging face 102 and the sheet metal part not only improves the connection fit with the sheet metal part, but also makes it difficult for the receiving cover 100 to be separated from the sheet metal part under the action of external forces, thereby improving the connection strength between the receiving cover 100 and the sheet metal part. After the connection between the receiving plug cover 100 and the sheet metal is stable, the drain plug cover 200 is embedded in the through cavity 104 until the clamping end 203 protrudes outward from the through cavity 104. At the same time, the drain plug cover 200 rotates so that the clamping end 203 is engaged with the edge of the lower end face 103. This not only achieves the purpose of fixing the drain plug cover 200 to the receiving plug cover 100, but also achieves the purpose of the drain plug cover 200 blocking the through cavity 104. In addition, relying on the limiting plate 201, on the one hand, the embedding of the drain plug cover 200 can be limited to prevent it from being embedded too deeply. On the other hand, it can have a secondary blocking effect on the through cavity 104, thereby improving the sealing between the drain plug cover 200 and the receiving plug cover 100.

[0023] Optionally, the receiving plug cover 100 is made of a commonly used compressible material such as EPDM (ethylene propylene diene monomer). This compressibility allows the receiving plug cover 100 to better fit the contact surfaces of the sheet metal component and the drain plug cover 200, thereby improving the airtightness between the receiving plug cover 100 and the sheet metal component, the receiving plug cover 100, and the drain plug cover 200.

[0024] Optionally, the drain plugging cover 200 is made of a hard plastic material such as PP (polypropylene). In this way, the hardness of the drain plugging cover 200 is greater than that of the receiving plugging cover 100. Due to the difference in hardness between the drain plugging cover 200 and the receiving plugging cover 100, the sealing between the drain plugging cover 200 and the receiving plugging cover 100 can be improved.

[0025] like Figure 3As shown, the lower end surface 103 is provided with a plurality of fixing protrusions 106 on the side facing away from the sheet metal engaging surface 102, and the fixing protrusions 106 are adjacent to the engaging grooves 105. Thus, the fixing protrusions 106 protrude away from the through cavity 104 and can be embedded in the engaging end 203 after the drain plugging cover 200 is rotated, thereby improving the connection strength between the drain plugging cover 200 and the receiving plugging cover 100, making it difficult for the two to shift or separate under the action of external forces.

[0026] like Figure 2 and Figure 3 As shown, a collapse groove 107 communicating with the through cavity 104 is provided between the sheet metal engaging surface 102 and the lower end surface 103. This collapse groove 107 provides a certain amount of deformation for the fixed contact 106 toward the lower end surface 103 when the drain plug cover 200 rotates, allowing the engaging end 203 to easily engage or disengage with the fixed contact 106. This effectively improves the efficiency of assembly and disassembly between the drain plug cover 200 and the receiving plug cover 100.

[0027] like Figure 4 As shown, a parallel engaging plate 204 is provided on the sidewall of the engaging end 203, adapted to engage with the engaging groove 105. Optionally, the engaging plate 204 can, on the one hand, limit the position of the drain plug 200, preventing the engaging end 203 of the rotating plug from being easily separated from the lower end surface 103. On the other hand, the engaging plate 204 can engage with the fixed contact 106, thereby enhancing the connection strength between the engaging end 203 and the lower end surface 103.

[0028] like Figure 4 and Figure 5 As shown, the side of the clamping plate 204 facing the blocking column 202 is provided with a fixing groove 205 adapted to the fixed synapse 106. In this way, the clamping plate 204 can be embedded with the fixed synapse 106 through the provided fixing groove 205, further improving the connection strength between the clamping end 203 and the lower end surface 103.

[0029] like Figure 5 As shown, a groove 206 is provided on the inner side of the clamping end 203, which is located between the clamping plates 204. Thus, the groove 206 can provide a certain amount of deformation for the clamping end 203 when the clamping end 203 is engaged with or separated from the fixed synapse 106, so that the clamping end 203 can be quickly engaged with the fixed synapse 106, thereby improving the efficiency of assembly and disassembly of the receiving plug cover 100 and the drain plug cover 200.

[0030] like Figure 4 and Figure 5As shown, a plurality of vertical plates 207 are provided on one side of the limiting plate 201 facing away from the through cavity 104. In this way, the vertical plates 207 can provide operating force points for the installation or separation of the drainage plug cover 200 and the receiving plug cover 100, making the installation or separation of the two more convenient.

[0031] Optionally, an anti-lost rope 300 is connected between the receiving plug cover 100 and the drain plug cover 200. In this way, the anti-lost rope 300 can prevent the drain plug cover 200 from being accidentally lost when the receiving plug cover 100 and the drain plug cover 200 are separated, thereby increasing the service life of the drain plug cover 200.

[0032] Finally, although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
