Connector structure with lock mechanism

Abstract

In the connector structure composed of the supply connection part for supplying the fluid and the receiving connection part for receiving the supply of the fluid, the connection can be reliably performed in the locked state by simple actions, and the release can be reliably performed by simple actions. take out. The connector structure includes a fixing mechanism (4) and a force applying mechanism (47), and the fixing mechanism (4) has an action part (44) that moves along with the connection action of the supply connection part (3) and the receiving connection part (2). ), with the movement of the action member (44), it is maintained in a locked state that fixes the connection state of the supply connection part (3) and the reception connection part (2), and the next push-in of the supply connection part (3) Operation, the action part (44) moves further, releases the locking state of the supply connection part (3) and the reception connection part (2), and the force application mechanism (47) separates the supply connection part (3) from the reception connection part (2) When force is applied in the direction of the fixing mechanism (4), fluid can be supplied from the supply connection part (3) to the reception connection part (2).

Description

technical field [0001] The present invention relates to a connector structure with a locking mechanism comprising a supply connection part for supplying fluid and a receiving connection part for receiving the supply of the fluid. Background technique [0002] As a conventional receiving device for using fluid and a supply device for supplying the fluid, for example, there is a combination of a fuel injection type igniter and a gas cylinder for fuel injection. The connector structure generally adopts the following structure: the injection port on the side of the igniter Valves are respectively provided at the discharge outlets on the side of the gas storage cylinder and the gas storage cylinder, and the two valves are opened due to the pushing action of the gas storage cylinder, so that the fluid in the gas storage cylinder is injected into the igniter (for example, refer to Japanese Publication No. 39-14343 and Japanese Mihiko Publication No. 3-35972). [0003] However, in ...

Problems solved by technology

[0003] However, in the conventional connector structure, the gas igniter as a receiving device for using fluid and the gas cylinder as a supply device for accommodating fluid and replenishing injection to the gas igniter are connected only when the fluid is replenished and injected into the gas igniter. , is not a mechanism that is always connected, so the mechanism is relatively simple

[0004] However, depending on the purpose of use, it is sometimes required that the receiving device is always connected to the supply device containing the fluid to supply the contained fluid. At this time, the mechanism as the connecting part can be simply constituted as having a pump on the receiving device side. The fluid delivery structure in the supply device, but it is necessary to install a fuel pump and its control mechanism on the receiving device side, which will make the receiving device complicated and hinder miniaturization

[0005] As mentioned above, since there is no need to provide a pump on the side of the receiver, it is preferable to supply the fluid using a supply device such as the above-mentioned gas cylinder that contains fluid in a pressurized state. However, when the supply device is not installed in a securely connected state, Then there is a problem of fluid leakage and poor fluid supply

[0006] In addition, in order to prevent the connected feeding device from falling off due to vibration, etc., it is necessary to provide a locking mechanism, and if the feeding device is inserted into the receiving device and installed, there is a problem that it is troublesome to remove the feeding device after use.
