Abstract

The utility model relates to a joint structure for an inlet and an outlet of a pump. The pump with a screw joint pump of the utility model comprises a pump body, a water inlet and a water outlet. The water inlet and the water outlet are positioned at the upper part of the pump body and are convex. The joint of the water inlet and the water outlet is provided with an inner screw thread and an outer screw thread. The inner screw thread, the outer screw thread and the pump body are integrally formed. The outer screw thread is a trapezoidal screw thread. When the utility model is used, a movable joint can be directly fixedly locked on the outer screw thread or the inner screw thread, a water pipe is directly inserted into a supporting hole of the movable joint, and the installation is completed. The pump of the utility model has the advantages of quick installation, convenient maintenance, and space saving. The utility model can be used by families. The pump is cast with stainless steel material and can not be rusted. The utility model can not pollute water source.

Description

Pump with screw joint pump

The utility model relates to a kind of structure of import and export joint of pump.

When engaging, the import and export of known pump hex union must be twined the leakproof glued membrane at the screw thread place, again its locking is put at lid, then water pipe is inserted, as water leakage phenomenon or maintenance take place, when needing replacing leakproof pad, more need loosen nut, take out screw rod, lid cover, just can change quite bothersomely, moreover screw rod is because of long-term relation in wet environment oxidation and rusting or mounting point, the puzzlement that more causes dismounting to be difficult for, maintenance is trouble more.In today of an inch of land is an inch of gold, everybody wishes to utilize minimum space, reaches maximum utility, and to improve standard of living, in order not take up space, everybody habitually is installed in the corner with pump as far as possible.The intake-outlet joint outward appearance of known pump is to about body outstanding rhombus substantially, so can not be close proximity to the corner when installing, causes the space waste, forming the dead angle sweeps difficult, moreover general home-use pump mostly cylinder iron makes, when not using for some time, and inner easily pig iron rust polluted source, influence healthy, and cause blade rust dead, can't turn round and damage, because above many shortcomings are arranged, order is installed and the user has the sense of inconvenience, reality that in addition improved necessity is arranged greatly.

It is rapid, easy to maintenance that the purpose of this utility model provides a kind of installation, and save the screw socket joint pump in space.

The utility model is realized by following manner.Screw socket joint pump includes the pump body and is positioned at the intake-outlet that pump body top projects upwards, this intake-outlet joint is provided with internal and external threads, be connected with water pipe in order to cooperate movable joint, the internal and external threads of above-mentioned import and export joint and pump body are formed in one, and its outside thread is a trapezoidal thread.

Be elaborated below in conjunction with accompanying drawing.

Stero constitutional diagram when Fig. 1 is the connector engages of known pumps.

Fig. 2 is the stereo appearance figure of known pumps.

Fig. 3 is the stereo appearance figure of screw socket joint pump.

Fig. 4 is the stero constitutional diagram of the connector engages of screw socket joint pump.

Fig. 5 is the section plan of the connector engages of screw socket joint pump.

As shown in Figure 1, when the import and export of known pumps engage, must with hex union 23 lockings on lid cover 22, then water pipe 5 be inserted; Need to change when preventing drain gasket 21, more need loosen nut 25, take out screw rod 24, lid cover 22, just can change quite bothersome.

As shown in Figure 2, the intake-outlet joint outward appearance of known pumps is substantially to the outstanding rhombus of body about 1, so can not be close proximity to the corner when installing, causes the space waste.

As shown in Figure 3, structure of the present utility model is to be provided with the intake-outlet 11 that projects upwards above pump body 1, intake-outlet joint 111 is provided with one-body molded internal and external threads, its manufacture method is outside the cured mould of body, do the cured mould of an outside thread separately, stick on the cured mould of body, cast with stainless steel with dewaxing process again and form, for the ease of the demoulding, outside thread is as trapezoidal thread, engage more quick and conveniently, and do not have the intake-outlet joint of general service pump outstanding and the trouble that can not be close proximity to the corner is installed.

As Fig. 4, shown in Figure 5, be to utilize movable joint commonly used during connector engages of the present utility model, include a T type bearing 3, there is dress leak-proof gasket 4 in the scrobicular ring 31 at its big end place, during combination T type bearing small end is inserted in retaining ring 2, and it is chimeric at big end place, constitute a movable joint, during joint if with retaining ring internal thread locking on intake-outlet joint 111 outside threads also can the retaining ring outside thread lock within it screw thread, again water pipe 5 being inserted joint gets final product, pump needs repairing or manages and change, as long as outward winding retaining ring, keeps in repair and gets final product.Quite save time conveniently.Screw socket joint pump can be home-use pump, and this pump is that stainless steel is cast, not pig iron rust, not polluted source

Claims

1, a kind of screw socket joint pump, include the pump body and be positioned at the intake-outlet that pump body top projects upwards, this intake-outlet joint is provided with internal and external threads, be connected with water pipe in order to cooperate movable joint, the internal and external threads and the pump body that it is characterized in that described import and export joint are formed in one, and its outside thread is a trapezoidal thread.
