In the description of the present invention, the meaning of a plurality of means is one or more, the meaning of a plurality of means is two or more, and larger, smaller, larger, etc. are understood as excluding the number, and larger, smaller, inner, etc. are understood as including the number. If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.

In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.

Referring to fig. 1 to 6, the hole plug for spraying in the embodiment of the present invention includes a plug piece 10 and a handle structure, and the handle structure is connected to a top surface of the plug piece 10. The handle structure includes at least three flaky handles 20, and the lateral surface of handle 20 is used for the inboard butt of the centre bore with wheel hub, and the lateral surface of handle 20 is from last inwards slope gradually down. In this embodiment, the inner side surface of the handle 20 refers to the side surface of the handle 20 close to the center of the tap piece 10, and correspondingly, the outer side surface of the handle 20 refers to the surface far from the center of the tap piece 10 and opposite to the inner side surface of the handle 20. Since the outer side surface of the handle 20 is gradually inclined inward from top to bottom, the handle structure is formed in a shape that is wide at the top and narrow at the bottom. When the plug is placed in the central hole of the hub, the outer side surface of the handle 20 abuts against the inner side of the central hole of the hub, and at the moment, the outer diameter of the upper part of the handle structure is larger than the inner diameter of the central hole of the hub, so that the handle structure is difficult to fall in the central hole of the hub. In the present embodiment, the outer diameter of the handle 20 means the diameter of a circle tangent to the outer side surface of each handle 20. In addition, the arrangement of the handle structure can also enable the plug to be more widely applied to hubs with different inner diameters of the central holes. Optionally, a holding opening 21 is formed on the handle 20, which facilitates a user to hold the handle structure, thereby conveniently taking and placing the plug.

It will be appreciated that the number of handles 20 is more than three and that the location of the handle structure in contact with the central hub aperture can be increased by adding handles 20, thereby making the relative position of the handle structure and the central hub aperture more stable. And preset included angles are formed between the end surfaces of every two adjacent handles 20, and the preset included angles are equal. The handles 20 are uniformly distributed, so that the integral stress of the handle structure is more uniform, and the handle structure is not easy to turn over. Specifically, taking the number of the handles 20 as three as an example, a preset included angle is formed between the end surfaces of two adjacent handles 20, and the preset included angles are all 120 °.

In some embodiments, the handle structure is detachably connected to the plug piece 10, so that the hub connector can adapt to hub center holes of different models and sizes, replacement of the plug piece 10 or the handle structure is facilitated, and maintenance cost is reduced. In some alternative embodiments, the handle structure is directly connected to the stopper plate 10, simplifying the structure. In other alternative embodiments, the handle structure is attached to the top surface of the plug sheet 10 by a gasket 30, the gasket 30 being located between the handle structure and the plug sheet 10. Because the handle structure is connected with the plug piece 10 through the gasket 30, the handle structure and the plug piece 10 are prevented from being worn when the handle structure and the plug piece 10 are disassembled and assembled.

Optionally, the gasket 30 is connected to the plug sheet 10 through a positioning pin 40, a first central hole is formed in the gasket 30, a second central hole is formed in the plug sheet 10, and the positioning pin 40 is inserted into the first central hole and the second central hole to be fixed. The positioning pin 40 is in interference fit with the first central hole and the second central hole, so that the gasket 30 and the plug piece 10 can be fixedly connected.

Optionally, the top surface of the gasket 30 is provided with at least three grooves 31, and the bottom surface of each handle 20 is provided with a protrusion 22, the protrusion 22 being capable of interference fit with the grooves 31. The handle 20 is inserted into the groove 31 through the protrusion 22 to achieve the connection of the handle 20 and the gasket 30. It is easily understood that a positioning space into which the positioning pin 40 can be inserted is formed between the inner side surfaces of all the handles 20, and the positioning pin 40 is inserted into the positioning space and sequentially inserted into the first center hole and the second center hole.

While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that the present invention is not limited to the details of the embodiments shown and described, but is capable of numerous equivalents and substitutions without departing from the spirit of the utility model as set forth in the claims appended hereto.
