Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the present invention, the following detailed description of the embodiments, structures, features and effects according to the present invention with reference to the accompanying drawings and preferred embodiments is as follows:
Example 1
Please refer to fig. 1, which is a schematic structural diagram of a plugging cover 1 of the present application. Referring to fig. 2 and fig. 3, fig. 2 is a cross-sectional view of the block cover 1 covering a hole 20 on a plane 2 (e.g., a car floor) in one direction, and fig. 3 is a perspective view of the block cover 1 in another direction. The closure 1 at least comprises a closure body 10 and a sealing element 11.
The blanking body 10 can be, for example, a flat plate-like element. As shown in fig. 1, the blanking body is a flat plate-like member extending in the XY plane. The closure body 10 of the plate-like member makes it versatile, not affected by the shape of the particular hole 20 and therefore unusable, and does not need to be provided in accordance with the shape of the hole 200. Moreover, the closure body 10 of a flat plate-like element can also have higher portability and operability, and the processing steps are fewer, thus saving the cost.
The closure body 10 may be a flat plate-shaped member made of metal, such as a galvanized steel plate; however, other metal materials are also possible, such as e.g. e-coat steel, e-coat galvanized steel, or stainless steel, tin-coated steel, etc., and can be produced, for example, from sheet metal scrap to save costs.
The thickness of the blanking cover body 10 (e.g., the thickness in the Z direction in fig. 2) may be between 0.3 and 1.5 mm, such as between 0.5 and 1.0 mm, such as 0.7 mm thick. In one embodiment, the thickness of the blanking cap body 10 may be, for example, the same or similar to the thickness of the plane 2 in which the holes 20 are located. However, the thickness of the closure body 10 is not necessarily limited by the thickness of the element in which the hole 200 is located.
The shape of the closure body 10 may be any suitable size or may be selected to fit the particular shape of the hole to be closed. In one embodiment, the blanking cap body 10 may be circular, i.e. a circular plate-like element. The circular element is easy to manufacture and has strong applicability. However, in another embodiment, since the plug body 10 may be manufactured using a sheet metal scrap, the shape of the plug body 10 may be set according to the specific shape of the scrap, and is not necessarily limited to a fixed shape. In one embodiment, the shape of the closure body 10 may also be designed to match the shape of the mounting surface to be covered, especially when the size of the mounting surface to be covered is small or the shape is special. For example, the blanking body 10 may be rectangular, for example square.
The size of the blanking cover body 10 is the smallest size as long as it can cover the cavity to be covered, and the largest size may be slightly the same as or slightly smaller than the size of the mounting surface to be covered, for example, less than 1 mm of the edge contour of the mounting surface to be covered. That is, the size of the closure body 10 can be designed to be small to be suitable for a case where the installation surface to be covered is small.
On the closure body 10, a sealing element 11 may be provided. The sealing element 11 is made of butyl rubber, which can be high temperature resistant butyl rubber. The butyl rubber has the advantages of good adhesive property, good sealing property, good sound insulation property and good waterproof and dustproof functions. The shape of the sealing element 11 is not limited as long as it can be completely covered by the plugging body 10 and completely cover the hole 20 to be covered. The sealing element 11 may be glued to the closure body 10. Specifically, the sealing member 11 may be adhered to the closure body 10 by the self-adhesive property of the butyl rubber itself, but may be adhered to the closure body 10 by other methods.
the sealing member 11 may be a flat plate-like member. The sealing member 11 may be a flat plate member having a circular outer periphery. For example, as shown in the embodiment of fig. 1 and 3, the sealing member 11 may be a hollow circular flat plate, i.e., a ring. As shown in fig. 1, the sealing member 11 is a flat ring shape lying on the XY plane with the axial direction being the Z axis. In this way, an annular portion 12 of the closure body 10 is produced which is located within the sealing element 11 and is not covered by the sealing element 11. In one embodiment, the inner ring portion 12 completely covers the hole 200 to be covered; at this time, the sealing element 11 can be completely adhered to the plane 2, so that the strength of adhering the sealing element 11 and connecting the plugging body 10 with the plane 2 is improved.
In one embodiment, the sealing element 11 may also be provided with a pattern to increase the friction of the sealing element 11. In particular, the face of the sealing element intended to be glued to the plane 2, i.e. the face facing away from the body of the closure, may be provided with a pattern. The pattern may be, for example, a cross-hatch pattern, or a straight line pattern.
In one embodiment, one face (e.g., XY plane in fig. 1) of the blanking cap body 10 may be circular. In one embodiment, the circular shape of the closure body 10 may be 30 to 60 mm, such as 40 to 50 mm, such as 43 to 47 mm, such as 45 mm. In one embodiment, one face of the sealing element 11 (e.g., the XY plane in fig. 1) may be flat plate annular. Wherein, in one embodiment, the outer edge of the sealing element 11 may be circular, and the diameter is slightly smaller than the circular diameter of the closure body 10, and may be 30 to 60 mm, for example 40 to 50 mm, for example 41 to 45 mm, for example 43 mm; on the other hand, the shape of the ring inner portion 12 (i.e., the shape of the inner edge of the sealing member 11) may also be circular, and the diameter may be 25 to 50 mm, for example, 30 to 40 mm, for example, 32 to 36 mm, for example, 34 mm.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
