Abstract

The invention discloses a method for a closed shell to be connected with an external part and a bolt used by the method. The method is suitable for connecting the closed shell or goods with shells not capable of being opened conveniently and the external part. The bolt comprises a head part and a rod part. The head part is in a long-strip shape and is perpendicular to the rod part. The head part extends towards the two sides of the rod part, and one side of the head part protrudes in the extension direction of the rod part, so that a butting block is arranged. According to the method, the bolt is used for connecting the closed shell and the external part.

Description

technical field

[0001] The present invention relates to the field of fasteners. Background technique

[0002] For some closed shells to connect external components, usually a hole that fits the bolt shaft is opened on the shell, and the bolts pass through the inside of the shell and connect to the external parts and then clamped by nuts. This method only supports the shell. Opened product. However, it is not suitable for objects that are integrally formed with the shell because the bolts cannot be put into the shell and passed out. For example, the connection between a square aluminum alloy and an external object, the end of the aluminum alloy can be inserted into the aluminum alloy by hand to pass the bolt out. , but for relatively internal positions, it cannot be achieved. Therefore, in the prior art, it is particularly difficult to install external components on the shell of an item whose shell is in a closed state or the shell is inconvenient to open, especially when co...
