An embodiment of the present invention provides a connecting device, referring to fig. 1 to 8, which are schematic structural diagrams of the connecting device according to the embodiment of the present application, and the connecting device includes: the device comprises a limiting mechanism 3.a, a resetting mechanism 3.d, a sealing mechanism 3.c, a valve body 3.e and a flow channel mechanism 3. b;
it should be noted that the functional components are components connected to the main system to ensure the safe operation of the main system or to implement some functions, such as valve components and other functional components.

it should be noted that the reset mechanism 3.d is a mechanism that can deform under the action of external force, and when the external force is removed, the reset mechanism 3.d can be restored to the initial state from the current deformation, or can be moved to a certain position under the action of external force, and when the external force is removed, the reset mechanism 3.d can be returned to the initial position from the current position.
The flow channel means 3.b is a means having an inlet and an outlet, and a fluid medium can flow from the inlet of the flow channel means 3.b, from the outlet of the flow channel means 3.b to the functional part 1.a connected to its first end.
The limiting mechanism 3.a is movably arranged on the valve body 3.e, the limiting mechanism 3.a can be moved to a first state and drives the runner mechanism 3.b to move to a conducting state, and an inlet of the runner mechanism 3.b in the conducting state is extended out of a second end of the valve body 3.e, which is used for being connected with the pipeline 1. c;

Through the connecting device disclosed above, through the resetting means that inside set up, and the runner mechanism that has export and entry, when needs switch on, through applying external force to stop gear, during exploring the entry of runner mechanism into the pipeline, make the fluid medium in the pipeline leading-in through the entry, and flow into the functional part article through the export, when the functional part article is dismantled to needs, only need remove stop gear's external force, withdraw the entry of runner mechanism in the valve body from the pipeline, make the fluid medium can't flow into the functional part article through the entry through the export, and set up the entry of runner mechanism in runner structure both sides, when fluid medium pressure is unstable or there is more impurity in the fluid medium in the pipeline, can prevent effectively that the functional product from appearing unusually, guarantee that the fluid medium can the steady operation.
Further, the limiting mechanism 3.a is movably arranged on the valve body 3.e, and the limiting mechanism 3.a can be moved to the first state position, so that the resetting mechanism 3.d is deformed and drives the flow channel mechanism 3.b to move to the conducting state position; the limiting mechanism 3.a can also move to a second state position, and the resetting mechanism 3.d can provide restoring force for the flow channel mechanism 3.b to move from the conducting state position to the closing state position.
It should be noted that the specific implementation of the limiting mechanism 3.a movably disposed on the valve body 3.e can be realized by providing threads on the limiting mechanism 3.a and the valve body 3.e, and the two threads are engaged with each other, but the specific implementation is not limited to the threaded engagement.
Based on the mutual meshing of the threads arranged on the limiting mechanism 3.a and the threads of the valve body 3.e, when the limiting mechanism 3.a is screwed into the valve body 3.e, the limiting mechanism 3.a is moved to a first state position, the reset mechanism 3.d can be deformed and drive the flow channel mechanism 3.b to move to a conducting state position, when the limiting mechanism 3.a is screwed out of the valve body 3.e, the limiting mechanism 3.a is moved to a second state position, and the reset mechanism 3.d can provide restoring force for the flow channel mechanism 3.b from the conducting state position to a closed state position.

And a is a limiting sheet which is mainly used for forming the whole self-locking structure and enabling the structure to move up and down when rotating.
The structure b is a flow channel structure and is a hollow mechanism, so that the medium can flow inside conveniently; the top is of a solid structure, so that a refrigerant is prevented from flowing into the top, and the sealing effect is realized during locking; the two sides are provided with holes, so that the fluid medium can conveniently flow in from the side.
