SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a flange loose joint connection structure of convenient fast-assembling.
In order to achieve the above purpose, the utility model provides a following technical scheme: comprises a loose joint nut, a loose joint core body and a sealing gasket which are assembled together,
the loose joint nut comprises a hole A and a hole B which sequentially penetrate through the loose joint nut, and the inner diameter of the hole A is larger than that of the hole B;
a notch C and a notch D are concavely arranged on the inner wall of the hole B, and an included angle between the notch C and the notch D is smaller than 180 degrees;
the loose joint core body comprises an upper connecting end connected with the pump body and a lower connecting end connected with the loose joint nut;
the external diameter of lower link is greater than the external diameter of last link to be provided with on the excircle of lower link with the side cut E of breach C looks adaptation, with the side cut F of breach D looks adaptation.
And the bottoms of the notch C and the notch D are both arc-shaped surfaces.
Wherein the inner wall of the hole A is provided with internal threads.
Contrast prior art not enough, the utility model provides a beneficial effect that technical scheme brought: when the novel movable joint core is used, the two ends of the pump body are provided with the novel movable joint cores, the movable joint nut penetrates the movable joint core at one end of the pump body firstly and then is provided with the sealing gasket, finally the movable joint core is integrally arranged on a pipeline of a water path system to be screwed, the system pipeline and the movable joint cores at the two ends of the pump body are axially compressed to realize sealing, and the movable joint core can be quickly disassembled and assembled, can improve the assembly performance and the usability and can reduce the installation space.

The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The present invention is further explained with reference to fig. 2 to 5.
A flange loose joint connecting structure comprises a loose joint nut 10, a loose joint core 20 and a sealing gasket 3 which are assembled together, wherein the loose joint nut 3 comprises a hole A and a hole B which sequentially penetrate through the hole A and the hole B, and the inner diameter of the hole A is larger than that of the hole B;
a notch C and a notch D are concavely arranged on the inner wall of the hole B, and an included angle between the notch C and the notch D is smaller than 180 degrees;
the loose joint core body 20 comprises an upper connecting end 21 connected with the pump body 4 and a lower connecting end 22 connected with the loose joint nut 3; the external diameter of lower link 22 is greater than the external diameter of last link 21 to be provided with on the excircle of lower link 22 with the side cut E of breach C looks adaptation, with the side cut F of breach D looks adaptation. During assembly, the loose joint core body 20 and the loose joint nut 10 are cut through the notch and the corresponding cut edge, the flange face of the loose joint core body 20 inclines by 30-45 degrees and can be turned into the loose joint nut 10 along the notch, the problem of interference between the flange face of the loose joint core body 20 and the loose joint nut 10 is solved, then the loose joint core body and the pump body pipe thread are compressed and sealed through the sealing gasket 3, and finally the loose joint core body and the pump body pipe thread are integrally arranged on a pipeline of a waterway system and extend into the loose joint nut 3 to be connected through the pipeline in a threaded mode, so that the assembling performance and the using performance can be improved, and the installation space can be reduced.
Further, the bottom of the notch C and the bottom of the notch D are both arc-shaped surfaces, so that the loose joint core body 20 can be conveniently installed.
Further, the inner wall of hole A is provided with the internal thread, quick and the pipe connection in the water route.
The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
