Detailed Description

The quick hose connector comprises an upper connector 1, a lower connector 3, a screwing ring 6 and a blocking cover 9 (refer to the attached figure 1 in the specification).

The upper joint 1 is in a cylindrical structure; two groups of claws 2 are symmetrically arranged at one end of the upper connector 1 (see the attached figures 2 and 3 of the specification). During assembly, the upper joint 1 is welded and installed on a dust discharging pipeline of a dust discharging vehicle.

The lower joint 3 is of a cylindrical structure; a limiting step surface 4 is arranged on the circumferential surface of one end of the lower joint 3 (refer to the attached figures 4 and 5 in the specification). The circumferential surface of the blocking cover 9 is provided with a limiting stepped surface 4 (refer to the attached figures 8 and 9 in the specification).

The quick hose coupling comprises two sets of tightening rings 6; two groups of operation lugs 5 are symmetrically arranged on the circumferential surface of the screwing ring 6; the surface of the screwing ring 6 at one side of the operation support lug 5 is provided with a clamping rotary rib 7 (refer to the attached figure 6 in the specification). The clamping rotary rib 7 is in a spiral structure (see the attached figure 6 of the specification).

The inner diameter of the screwing ring 6 is consistent with the outer diameter of the lower joint 3 and the plug cover 9. When the connector is assembled in this way, the screwing ring 6 can be sleeved on the lower connector 3 (see the attached drawing 7 in the specification), and the limiting stepped surface 4 at one end of the lower connector 3 can limit the screwing ring 6, so that the problem that the screwing ring 6 slips from one end of the lower connector 3 is solved. The circumferential surface of the other end of the lower joint 3 is provided with a plurality of connecting grooves 8 (refer to the attached figures 4 and 5 in the specification). The purpose of thus arranging the joining groove 8 is: with the mode through setting up the joint groove 8, the mode of lower clutch 3 end in order to peg graft the hose during messenger's assembly, with the hose connection back and use the clamp with its fixed in lower clutch 3 time, joint groove 8 can strengthen and the hose between the frictional force to the risk of taking place the pine between lower clutch 3 and the hose takes place to take off.

When the ash discharging vehicle provided with the quick hose connector is in a non-ash discharging state, namely when a valve on an ash discharging pipeline of the ash discharging vehicle is closed, firstly, a group of screwing rings 6 are sleeved on the blocking cover 9; the spacing ladder face 4 on the blanking cover 9 can inject the ring 6 of screwing on the blanking cover 9 this moment, has avoided the ring 6 of screwing to take place to loosen from the one end of blanking cover 9 and take place to take off. Then the screwing ring 6 and the plugging cover 9 are moved together to correspond to the end head of the upper joint 1, the tail end of a clamping screwing rib 7 on the screwing ring 6 corresponds to the bayonet of the clamping jaw 2 on the upper joint 1, and then the screwing ring 6 is screwed through the operation support lug 5, so that the clamping screwing rib 7 is clamped into the bayonet of the clamping jaw 2. In the process, as the clamping rotary rib 7 is in a spiral structure, when the clamping rotary rib 7 is clamped into the bayonet of the clamping jaw 2, the screwing ring 6 gradually compresses the limiting step surface 4 of the screwing ring 6 under the matching of the upper joint 1, and finally the blocking cover 9 is compressed and fixed at one end of the upper joint 1 (see the attached drawing 11 in the specification). One end of the upper joint 1 can be sealed by the blocking cover 9, so that foreign matters outside are prevented from entering an ash discharging pipeline of an ash discharging vehicle.

When the dust discharging vehicle provided with the quick hose connector needs to discharge dust, the screwing ring 6 at one end of the upper connector 1 is firstly rotated reversely, so that the screwing ring 6 and the blocking cover 9 are separated from the upper connector 1. Then the lower connector 3 provided with the hose and the screwing ring 6 is moved to be corresponding to the end head of the upper connector 1, the tail end of a clamping screwing rib 7 on the screwing ring 6 is corresponding to the bayonet of the clamping jaw 2 on the upper connector 1, and then the screwing ring 6 is screwed through the operation lug 5, so that the clamping screwing rib 7 is clamped into the bayonet of the clamping jaw 2. When the screwing ring 6 is screwed, the lower joint 3 and the upper joint 1 are pressed and fastened, and the valve on the ash discharge pipeline is opened to finish the ash discharge work. After the ash discharging work is finished, the valve is closed, the lower connector 3 is disassembled, and the upper plugging cover 9 is assembled.

The quick hose has a compact structure and an ingenious design; the hose can be connected without hammer knocking, the quick hose connector adopts the claw 2 structure for connection, and has the characteristic of high strength, so that the problems of high operating strength and high possibility of damage existing when the hammering union type hose connector is used by a dust discharging vehicle are solved, and the quick hose connector is particularly suitable for the requirement of discharging the dust discharging vehicle.
