Abstract
The utility model discloses a hose connecting device. The hose connecting device comprises two connector bodies which are the same in structure and matched with a hose. A sealing ring is arranged at the lateral end of each connector body, and a connecting body, a buffering ring and a clamping hoop which is used for enabling the buffering ring and the hose to be compressed on each connector body are installed outside the wall of each connector body. The connecting bodies and the connector bodies are fixed through clamping springs. A plurality of extending connecting claws are arranged on the outer circumference of each connecting body. The connecting claws on the two connecting bodies are correspondingly arranged to form connecting buckles used for connecting the two connecting bodies. The hose connecting device further comprises a locking connecting block which is used for preventing the connecting buckles from being disengaged after the connecting bodies on the two connector bodies are connected. The hose connecting device overcomes the defects that in the prior art, due to the fact that a hose connector product is high in weight and after the connecting bodies and the hose are connected to bear high-pressure liquid, the hose cannot rotate, so that the clamping hoops and the connector bodies are easy to disengage, and therefore liquid leakage is not enough, and has the advantages of being simple in structure, convenient to install, dismantle and operate, reliable in work, high in pressure resistance, and capable of effectively protecting the clamping hoops of the hose due to the fact that the connector bodies can rotate freely inside the connecting bodies.
Description
Technical field
The utility model belongs to indusion tube joint technical field, is specifically related to a kind of hose connection device.
Background technique
At present, domestic for bigbore hose coupling for delivery of liquid, realize sealing between joint and the flexible pipe by clip between its fittings body and the flexible pipe, fittings body and connecting body are merged into part of fittings body, this connecting means is simple, convenient, in order to carry highly pressurised liquid, an end of joint adopts two pairs of clips to be connected (as shown in Figure 8) with flexible pipe usually, prevents leak of liquid and the fracture of reply clip.But adopt the method cost height, product weight is heavier, and because after fittings body and connecting body merge into part of fittings body, and fittings body is connected with flexible pipe and bears the highly pressurised liquid rear hose and can't rotate, make clip and fittings body break away from easily, cause leak of liquid.
