Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a composite nozzle includes a nozzle body 1 and a nozzle 2, the right end of the nozzle body 1 is fixedly connected to the left side of the nozzle 2, the side surface of the nozzle body 1 is movably connected to the inner wall of a circular tube 3, the inner wall of the circular tube 3 is fixedly connected to the surface of a connecting tube 4, the circular tube 3 is located on the left side of the nozzle body 1, the edge of the right end of the circular tube 3 is provided with a circular groove 5, the horizontal axis passing through the center of the circular groove 5 coincides with the horizontal axis of the circular tube 3, the side surface of the nozzle 2 is fixedly connected to a fixing ring 6, the fixing ring 6 is used for connecting an insertion tube 7, the insertion tube 7 is fixedly connected to the left side of the fixing ring 6, the insertion tube 7 is inserted into the circular groove 5, the side surface of the insertion tube 7 is fixedly connected to the inner wall of the circular ring 8, the side, one side that fixed block 9 is close to pipe 3 has seted up circular slot 10, one side fixedly connected with spring 11 that pipe 3 was kept away from to circular slot 10 inner wall, the one end fixedly connected with movable block 12 of circular slot 10 inner wall is kept away from to spring 11, the surface of movable block 12 and the surperficial swing joint of intubate 7, one side that pipe 3 was kept away from to fixed block 9 is provided with bolt 13, bolt 13 is close to the one end of movable block 12 and runs through fixed block 9 and with the surperficial swing joint of movable block 12.

In particular, the lateral surface of the cannula 7 is provided with a recess 14.

In this embodiment, the position of the nozzle 2 cannot be fixed well by virtue of the friction between the movable block 12 and the insertion tube 7, and therefore, the fixing is more firm by the cooperation of the groove 14 and the movable block 12.

Specifically, the groove 14 is saw-toothed, and one side of the movable block 12 close to the groove 14 is matched with the shape of the groove 14.

In this embodiment, the indentation 14 can make the extended nozzle body 1 fixed more firmly, and the nozzle 2 will not move left easily.

Specifically, a thread groove 15 is formed in the position, corresponding to the bolt 13, of the fixing block 9, and the inner wall of the thread groove 15 is in threaded connection with the surface of the bolt 13.

In this embodiment, the bolt 13 is tightened, the bolt 13 rotates along its axis and moves to a position away from the insertion tube 7, and the bolt 13 is loosened, and the bolt 13 rotates in the opposite direction along its axis and moves to a position away from the insertion tube 7.

Specifically, the number of the fixed blocks 9, the springs 11, the bolts 13, the circular grooves 10 and the movable blocks 12 is two.

In this embodiment, after the length adjustment of the nozzle body 1 is completed, the insertion tube 7 is extruded through the two fixing blocks 9, so that the stress of the insertion tube 7 is more uniform, and the fixation is more firm.

The utility model discloses a theory of operation and use flow: when the spray pipe is used, the bolt 13 is unscrewed, then the circular pipe 3 is held, the nozzle 2 moves rightwards, the insertion pipe 7 moves rightwards along the annular groove 5, the inner wall of the groove 14 continuously extrudes the movable block 12, so that the spring 11 continuously shortens and extends, when the nozzle 2 moves to a required position, the nozzle 2 stops moving, the bolt 13 is screwed, the bolt 13 is abutted against the movable block 12, the movable block 12 is tightly pressed in the groove 14, so that the moving position of the nozzle 2 is fixed, the length of the spray pipe body 1 can be adjusted, the nozzle 2 can be close to the surface of steel, when liquid is sprayed, the liquid enters the interior of the spray pipe body 1 from the connecting pipe 4, due to the tight fit between the spray pipe body 1 and the inner wall of the circular pipe 3, the liquid is difficult to leak from a gap between the spray pipe body 1 and the inner wall of the circular pipe 3, if the liquid leaks from, by the tight fit between the ring 8 and the inner wall of the annular groove 5, the liquid is again blocked and is less likely to leak.

In conclusion, the composite type spray pipe solves the problem that the length of the common composite type spray pipe in the prior art is not adjustable by arranging the round pipe 3, the connecting pipe 4, the inserting pipe 7, the ring 8 and the movable block 12.
