Abstract
The invention relates to the technical field of connecting joints, in particular to a hose connecting structure and a dust collector using the same. The hose connecting structure comprises a hose connector and a clamping ring, wherein the connector is fixedly arranged at the end of a hose, and the clamping ring is rotationally connected with the hose under limiting of the hose connector. The clamping ring comprises a clamping ring body and an elastic limiting part arranged at one end of the clamping ring body, wherein the inner diameter of the clamping ring body is not smaller than the outer diameter of the hose connector. When the clamping ring penetrates into the hose through the hose connector, the elastic limiting part can generate elastic deformation to expand towards the outer side, and after the clamping ring passes through the hose connector, the elastic limiting part restores in shape and cooperates with the hose connector to form limiting on the clamping ring. The invention further provides the dust collector using the hose connecting structure. The elastic limiting part is arranged at one end of the clamping ring body of the clamping ring, so that the clamping ring is placed in the hose, and the elastic limiting part cooperates with the hose connector to form limiting on the clamping ring. Thus, the clamping ring can be placed in the hose with the hose connector.
