Embodiment Construction
[0020] Further description will be made below in conjunction with the accompanying drawings.
[0021] Such as image 3 As shown, the dustproof plug of the embodiment of the present invention includes a flat cap-shaped plug body 10, a fixed shaft 20 disposed at one end of the cap-shaped plug body 10, and a buckle body 30 inserted into a hole to be dustproofed. The fixed shaft 20 is a stepped shaft structure, including a main shaft 202 with a smaller diameter, a blocking portion 204 formed after a smooth transition at the tail of the main shaft 202 , and a through hole shaft 206 connecting the blocking portion 204 and the cap-shaped plug body 10 . The fixing shaft 20 is arranged perpendicular to the flat surface of the cap-shaped plug body 10 . The diameter of the via shaft 206 gradually increases from the end connected to the blocking portion 204 to the end connected to the cap-shaped plug body 10 , so as to form an arc transition at the connection with the cap-shaped plug bod...

The invention relates to a dustproof plug comprising a flat cover-like plug body and a stationary shaft arranged at one end of the cover-like plug body. The stationary shaft is in the stepped shaft structure and comprises a spindle with less diameter, a barrier part and a via shaft, wherein the barrier part is formed after smooth transition amplification via the tail part of the spindle and the via shaft is connected with the barrier part and the cover-like plug body; the diameter of the via shaft from one end connected with the barrier part to one end connected with the cover-like plug body is gradually enlarged; and arc transition is formed at the joint of the via shaft and the cover-like plug body. The invention also relates to a sealing locknut structure using the dustproof plug. Whenboth ends of the via shaft of the dustproof plug are stressed, the end with larger diameter and the cover-like plug body are greatly deformed as a result of large diameter and arc transition; the endwith smaller diameter is inlayed to the via shaft inside the via hole as a result of smaller diameter and no arc transition with less deformation. Under the same drawing force, the end of the via shaft with smaller diameter is hard to pass through the via hole on the shell as a result of less deformation amount distributed, thereby effectively preventing the dustproof plug from pulling away the via hole.
Description
【Technical field】 [0001] The invention relates to a dustproof device, in particular to a dustproof plug and a sealing and anti-loosening structure using the dustproof plug. 【Background technique】 [0002] Charging ports or other interfaces of small lamps or small communication devices generally require rubber dustproof plugs to prevent dust during use. A traditional dust plug such as figure 1 As shown, the dustproof plug includes a flat cover-shaped plug body 1, a fixed shaft 2 and a buckle body 3 respectively arranged at both ends of the cover-shaped plug body 1, and the fixed shaft 2 and the buckle body 3 are matched with the holes around the interface respectively. , the dustproof plug is fixed by the fixed shaft 2 at one end, and is fastened or opened with the device by the buckle body 3 at the other end, thereby covering or exposing the interface. The fixed shaft 2 generally adopts a stepped shaft structure, which has a small-diameter main shaft 21, a blocking portion...
