The purpose of the utility model can be realized by the following technical proposal: a novel quick joint structure comprises a hollow joint body and is characterized in that the joint body is an external thread joint, and the middle part is provided with a hexagon nut which is integrated with the connector body, both ends of the connector body are connected with the nuts by screw threads, a hollow nylon sleeve is coaxially arranged in the connector body, opening snap springs are respectively arranged between the screw caps arranged at the two ends of the connector body and the two ends of the nylon sleeve, the outer end part of the nut is provided with a brim which is gradually reduced in the radial direction towards the central axis direction of the joint body, a first chamfer which is jointed with the inner wall of the brim is arranged at the position, corresponding to the inner wall of the brim, of the outer end part of the open snap spring, both ends of the outer peripheral wall of the nylon sleeve are jointed with the inner end part of the open snap spring, and a second chamfer which is gradually reduced from the peripheral wall of the nylon sleeve to the central axis direction of the joint body is arranged at the position where the two parts are attached to each other.

In the above-mentioned novel quick joint structure, be interference fit between joint body and the nylon cover.

In the above-mentioned novel quick-operation joint structure, the size of the opening of opening jump ring is between 2mm to 3 mm.

In the above-mentioned novel quick joint structure, the chamfer length of the first chamfer is between 3mm and 4 mm.

In the above-mentioned novel quick joint structure, the chamfer length of the second chamfer is between 1mm and 2 mm.

Compared with the prior art, the quick joint structure has the following advantages:

1. the novel quick joint structure is provided with the nut and the opening clamp spring, when a pipe fitting is connected, the nut is matched with the threads on the joint body to rotate, the opening of the opening clamp spring is closed, the pipe fitting can be fixed, and the novel quick joint structure has the advantages of quick connection and convenience in disassembly;

2. be provided with the nylon cover in this novel quick-operation joint structure, after the pipe fitting inserts and the access joint body is inside, because the nylon material has that toughness is good, the surface is smooth, coefficient of friction is little, wear-resisting, fatigue resistance can outstanding advantage, along with the twist of nut, the opening jump ring draws close toward the inside direction of joint body thereupon, the nylon cover can remove in the joint body, and the chamfer that nylon cover both ends set up can be inconsistent to this internal bending of joint and with the pipe fitting, plays sealed effect.
