Abstract

The utility model discloses a quick-adjusting joint for water pumps, which is used for connecting a water pump outlet and a water delivery hose, comprising a flange connection tube, an external tube with a convex shoulder, a press disk, and washers for preventing leakage. Some extending end heads of the external tube are provided with convex teeth which can conveniently make the direction of water delivery adjusted, and the convex teeth can connect or dismount water delivery hose rapidly and easily. The utility model has the advantages of convenient work and convenient transport.

Description

Quick-adjusting joint for water pumps

The utility model relates to a kind of joint of pump outlet.

The hose coupling of the water outlet of existing Centrifugal water pump nearly all is straight, flange is taken over has minority to bend, but also be dead, cause joint be connected with water pump body fastening after, the bending direction of joint can't change, the use of feed water pump has brought very big inconvenience, for this reason, the domestic people of having has designed, has made and sold the screwed movable joint of upper end collar extension that a kind of flange is taken over, improved the convenience of using, but the processing of this screw thread is convenient inadequately, and the installation and removal of flexible pipe and outer tube are also convenient inadequately.

The purpose of this utility model will overcome the shortcoming of existing pump outlet joint exactly, and it is more convenient to design a kind of manufacturing, and dismounting and the direction of adjusting joint be movable joint eaily also.

The purpose of this utility model reaches like this: it also has flange to take over and shouldered outer tube, but the upper-end surface that flange is taken over is a Flange Plane, the jointing place that this plane and flange are taken over endoporus is shaped on recess, wherein place leak-proof gasket, also the platen of useful bolton joins with it on the flanged surface of flange adapter upper-end surface, fastens in order to the convex shoulder with outer tube, and small gap is arranged between convex shoulder and the platen, be preferably the gap that is slidingly matched, so that allow outer tube rotate along its tubular axis.Install in order to be more convenient for, platen can be cut into two approximate semicircle pieces open from its a certain string that differs not too big with diameter, can also process screw thread at the external part head of its outer tube, in order to be connected with the cover that connects that has at least two double wedges; Perhaps simply directly make at least two double wedges, save the cover that connects of band double wedge, be connected so that connect cover with the flexible pipe of band piece mouth and groove at the external part head of outer tube.

Since the utility model not be used in flange take over to go up the external part head of machining screw, particularly outer tube and directly make double wedge after, not only convenient processing and manufacture, and flexible pipe and joint be connected and the adjustment of joint direction all more convenient.

Describe below in conjunction with embodiment and accompanying drawing.

Fig. 1 is the sectional view according to the threaded water pump Fast Activities of the external part head joint of a kind of outer tube of the utility model design; Fig. 2 is the partial view of analysing and observe of the water pump Fast Activities joint that has four double wedges of the external part head according to the another kind of outer tube of the utility model design; Fig. 3 is the partial view of analysing and observe along its A-A face.

With reference to accompanying drawing, it is Flange Plane that flange is taken over 1 upper-end surface 11, is shaped on recess 13 in the jointing place of this plane and the endoporus 12 of flange adapter 1, wherein is placed with leak-proof gasket 2, and this packing ring can be made with rubber, plastics.On the upper-end surface 11 of flange adapter 1, there are the outer tube 3 and the platen 4 of band convex shoulder 31 to join with it, platen 4 usefulness bolts 5 are fastened on flange and take on 1, the annular groove 41 of platen 4 fastens the convex shoulder 31 of outer tube 3, between the corresponding contact face of the end face of convex shoulder 31 and cylindrical and platen annular groove 41 small gap is arranged, so that outer tube 3 is able to rotate along its tubular axis.Platen 4 can be all-in-one-piece, also can be two formulas cutting into two approximate semicircles along its a certain string place that differs not too big with diameter open.Can make the endless belt that the flexible pipe that prevents to be attached thereto gets loose at the external part head 32 of outer tube 3, also can process screw thread 33, in order to (double wedge can be rectangular with having at least two double wedges, but wedge shape preferably) connecing cover (outsourcing piece, cooperation part or self-made components) connects, can not make screw thread 33 at external part head 32 yet, see Fig. 2 but directly make at least two double wedge 34(), with can connect cover (outsourcing piece) with the flexible pipe that has breach and groove that it matches and be connected, thereby save the cover that connects that has double wedge.

During use, arbitrarily conversion outer tube 3 bends towards, adapting to the needs of operation, owing in flange is taken over 1 recess 13, be provided with packing ring 2, so water can not spill from this, when carrying migration water pump, can unload and connect the flexible pipe that interlocks of cover with double wedge and connect cover and get final product, needn't unscrew the bolt 5 on the platen 4, also needn't unload bottom hose from connecing to put, fast but also easy, be a kind of more novel water pump movable joint really not only.

Claims

1, a kind of water pump joint, comprise that flange takes over 1, has the outer tube 3 of convex shoulder 31, leak-proof gasket 2, it is characterized in that: the upper-end surface 11 of flange adapter 1 is Flange Plane, this plane and endoporus 12 jointing places are shaped on recess 13, have leakproof gas ket 2 to be placed in the recess 13, the fastening platen that has annular groove 41 4 of also useful bolt 5 on flange is taken over 1 upper-end surface 11, the convex shoulder 31 of outer tube 3 is fastened, between the annular groove 41 of convex shoulder 31 and platen 4 small gap is arranged.

2, by the described water pump joint of claim 1, it is characterized in that: platen 4 is two semicircular pieces cutting open from a certain string that differs not too big with diameter.

3, by claim 1 or 2 described water pump joints, it is characterized in that: the external part head 32 of outer tube 3 has screw thread 33.

4, by the described water pump joint of claim 2, it is characterized in that: the head 32 of the external part of outer tube 3 is shaped at least two double wedges 34.
