    Abstract: Disclosed is a pipe connector structure, comprising a connector body (100), a supporting seat (200), a housing (300) and an elastic member (400), wherein a first end of the supporting seat is sheathed outside the connector body, a second end of the supporting seat is separated from the connector body, and an accommodation cavity (110) is formed between an inner wall of the supporting seat and an outer wall of the connector body; a first end of the housing is sheathed outside the supporting seat and engaged with the supporting seat, and a second end of the housing is located outside the second end of the supporting seat such that a tightening cavity (120) is formed between an inner wall of the housing and the outer wall of the connector body; an insertion port (310) for the insertion of a pipe is formed between an end portion at the second end of the housing and the connector body; and the elastic member is sheathed outside the connector body and is located in the tightening cavity, and a channel for the passage of the pipe is formed between the elastic member and the connector body. In use, the pipe is inserted through the insertion port such that the elastic member can be sheathed outside the pipe. When the pipe is pulled outwardly, the elastic member moves with the pipe and gradually tightens the pipe so as to prevent the pipe from separating from the pipe connector structure. This pipe connector structure is easy to install and operate.

    Abstract: A pipe fitting joint assembly, comprising: a guide sleeve (12), provided with a first concave-convex structure (121) on the outer wall of one end thereof; a connecting body (11), provided with a second concave-convex structure (111) on the inner walls of both ends thereof; and an inner gear ring (23), provided with a third concave-convex structure (231) on an inner ring thereof and a fourth concave-convex structure (240) on an outer ring thereof. The inner gear ring (23) is concentrically inserted into the connecting body (11); the fourth concave-convex structure (240) and the second concave-convex structure (111) are in interference fit; the guide sleeve (12) is concentrically inserted into the inner ring gear (23) of the connecting body (11); and the first concave-convex structure (121) and the fourth concave-convex structure (240) are in clearance fit therebetween using a moving interference manner. During use, the guide sleeve and the inner gear ring rotate relative to each other, and the first concave-convex structure and the third concave-convex structure scrape against each other due to movement interference, thus generating friction sound and a vibrating feeling when touched by a hand. A user may thus determine whether a pipe is installed correctly by listening for a friction sound and feeling for vibration.

    Abstract: A pipe joint structure including a joint body, a support seat, a housing and an elastic member is disclosed. A first end of the support seat is sleeved on the outside of the joint body, a second end of the support seat is disposed to be separated from the joint body, and an accommodating cavity is defined between an inner wall of the support seat and an outer wall of the joint body. A first end of the housing is sleeved on the outside of the support seat and engaged with the support seat, a second end of the housing is disposed beyond the second end of the support seat, so that a contraction cavity is defined between an inner wall of the housing and the outer wall of the joint body; an insertion opening through which a pipe can be inserted is defined between the joint body and the second end of the housing. The elastic member is sleeved on the outside of the joint body and disposed in the contraction cavity; a passage through which the pipe can pass is defined between the elastic member and the joint body. In use, the pipe is inserted through the insertion opening, so that the elastic member can be sleeved on the outside of the pipe. When pulling the pipe outward, the elastic member moves along with the pipe and gradually holds the pipe tightly, thereby preventing the pipe from detaching from the pipe joint structure.
