頭部への装着構造に関する。[Detailed Description of the Invention] <Industrial Application Fields> The present invention is designed to prevent the head of the panel joining bolt that connects the joining flanges of the unit panels existing in the tank of an assembled aquarium from moisture in the tank. This invention relates to a structure for attaching a cover to the head of a bolt, which is used to protect the head of a bolt from rusting due to water vapor.

水密状にカバーする構造が採られている。<Conventional technology> Conventionally, when covering the head of a bolt, a fitting hole is drilled in the bolt head, and a support shaft protruding from the lower surface of the cover body is press-fitted into the fitting hole. By doing so, a structure is adopted in which the cover body covers the bolt head in a watertight manner.

式自体の作業性も労力を要する。(Utility Model Application No. 52-50161) However, in the case of such a conventional example, when the cover itself is replaced due to corrosion due to long-term use, for example, the support shaft hugs the fitting hole and is difficult to remove. Otherwise, there is a risk that the cover body and the support shaft may be damaged and cannot be replaced, and the press-fitting method itself requires labor.

Protrusions are integrally formed inward on the wall surface of the storage chamber at appropriate intervals or facing each other, and these protrusions are connected to the notches via a notch formed on the outside of the opposing bolt head. The bolt is rotatably locked in a recess formed between the bolt head and the screw shaft.

Attach the cover body by rotationally locking it in the recess formed between the notch, rotate the protrusion, and guide the notch with the protrusion positioned in the recess directly below the notch. Remove the cover body.

This is the head of the bolt in nuts 1 and 2 that fastens the nut 2 to the screw shaft 1'', and the above protrusion
A notch ₂ that is slightly wider than the protrusion a ₂ and reaches the base end of the screw shaft 1'' is provided on the outside facing a 2, and a recess 3 that continues to the notch 2 and extends in the circumferential direction. .

Since it is rotatably locked in the recess between the bolt head and the screw shaft, which is formed continuously with the notch, through the notch formed on the outside, it can be installed and removed from the bolt head with one touch. It can be done formally. Therefore, it is possible to easily maintain the bolt part without breaking it or making it impossible to replace it as in the conventional case, and it is possible to provide a cover structure for the bolt head that takes into account the three items of replacement, installation, and watertightness function. . As a result, we were able to achieve our intended purpose.
