Problems solved by technology

[0004] However, the conventional connection checking mechanism described in the above-mentioned Patent Document 1 has a structure in which the tester pushed by the flange portion of the pipe is exposed to the outside, so the exposed area is determined by the thickness of the flange portion of the pipe. When the flange part is thin, there is a problem that the exposed area of ​​the tester becomes small and it becomes difficult to check visually.
Therefore, in order to secure the exposed area of ​​the tester, the shape of the piping (flange portion) may be limited
[0005] In addition, in the above-mentioned conventional connection confirmation mechanism, when the user inserts the pipe into the connector at an angle by mistake, etc. and pushes the checker in the direction of expansion at the front end of the pipe, there is a possibility that the two may not be connected even though the two are not connected. state, but the checker showing the combined state is pushed and exposed to the outside

Abstract

[Object] When two components are connected, a connection confirming mechanism is provided, which can carry out a display of a completion of connection state with an easily viewable size and prevent a false display of the completion of connection state. [Means of Solving Problem] A connection confirming mechanism, including a lock component 10 maintaining a completion of connection state of two components and a means, which can visually confirm the above-mentioned completion of connection state, has a structure comprising a pipe 2 including a projection and a connector 1 connected with a pipe. The connector is provided in a state wherein a connecting display component 8 is urged to one side relative to a housing 6, and when the pipe is completed to be fastened and connected with the connector, an urging force is released and the connecting display component moves, so that a visual connecting confirmation can be possible from the connector.

Description

technical field [0001] The present invention relates to a connection confirmation mechanism for visually confirming the completion of the connection when two members are connected. Background technique [0002] As a prior art related to such a connection confirmation mechanism, for example, the following structure is known: in the connection confirmation mechanism used to connect the pipe and the connector, a stopper member for preventing the pipe from coming off from the connector main body is provided. There is an anti-loosening protrusion that cooperates with the flange of the pipe, and when the flange of the pipe is connected, the anti-loosening protrusion is pushed up during the process of passing through the stopper, so that the stopper is expanded, so that it is arranged in the The checker on the front side of the stopper member is pushed and exposed to the outside by the flange portion (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese U...
