3. The quick assembly valve body structure according to claim 1, characterized in that: The elastic member is a spring or an elastic ring structure.

4. The quick assembly valve body structure according to claim 1, characterized in that: The valve body (1) further comprises an inner cover (2), wherein the inner cover (2) is arranged on the inner side of the valve body (1), the inner cover (2) comprises a top end and a main body, the top end of the inner cover (2) is connected to the top of the main body, the main body of the inner cover (2) is a circular cylindrical structure, the outer diameter of the top end of the inner cover (2) is greater than the outer diameter of the main body of the inner cover (2), the elastic member is sleeved on the outer side of the main body of the inner cover (2), and the elastic member and the ejector pin (4) are clamped in the valve body (1) through the top edge of the inner cover (2).

5. The quick assembly valve body structure according to claim 1, characterized in that: A stop hook (53) is provided at the top end of the stop claw buckle (5), and a claw buckle groove (112) is provided inwardly on the top edge of the valve body (1). From the initial state to the locked state, the stop hook (53) is always stuck in the claw buckle groove (112). In the locked state, the end of the stop hook (53) extends to the outside of the valve body (1).

6. The quick assembly valve body structure according to claim 1, characterized in that: A push rod (54) is provided at the bottom end of the stop claw (5), and the top of the push rod (54) is kept tilted downwardly toward the outer wall of the valve body (1). The top of the push rod (54) is used to abut against the hole edge structure of the mounting hole to receive force, and the push rod (54) enters the claw hole (111) under the action of the force.

7. The quick assembly valve body structure according to claim 1, characterized in that: At least one of the valve body (1), the backstop claw buckle (5) and the elastic buckle is made of high-strength plastic or elastic metal.

8. A method for quickly assembling a valve body structure, characterized in that: The quick assembly valve body structure according to any one of claims 1 to 7 is adopted, and the installation method includes the following steps: S1, checking and ensuring that the quick assembly valve body structure is in the initial state, and placing the valve body (1) into the mounting hole; S2, pushing the quick assembly valve body structure in, the tail end of the anti-retraction claw buckle (5) abuts against the edge of the mounting hole and is gradually retracted to the claw buckle hole (111) under force, and at the same time, the anti-retraction claw buckle (5) starts to rotate, and the anti-retraction teeth of the anti-retraction claw buckle (5) squeeze the elastic clip, and the top end of the anti-retraction claw buckle (5) gradually extends outward from the valve body (1); S3, the anti-retraction claw buckle (5) continues to rotate, and when the bottom end of the anti-retraction claw buckle (5) is completely retracted to the inner side of the outer peripheral surface of the valve body (1), the elastic clip restores its deformation, so that the anti-retraction teeth just clamp the elastic clip, and at the same time, the top end of the anti-retraction claw buckle (5) extends out of the valve body (1) and is locked at the mounting hole.
