Life；The fixed effect of cable and flange is bad and easy to wear.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide, a kind of service life is long, structure is strong
The immersible screw pump spent.
To achieve the above object, the utility model provides following technical scheme：A kind of immersible screw pump, including successively
Machine barrel, water inlet housing, stator sleeve and the delivery chamber of connection, machine barrel is interior to be provided with stator rotating shaft, and screw rod, stator sleeve are provided with stator sleeve
It is connected between water inlet housing by flange, it is characterized in that：Universal joint is provided with the water inlet housing, universal joint both ends are all provided with
There is the nut for being respectively used to be connected with stator rotating shaft and screw rod, universal joint periphery wall is provided with holding circle.
The utility model is further arranged to：It is connected through a screw thread between the stator sleeve and flange, stator sleeve is with extruding
Room is also by threaded connection.
The utility model is further arranged to：The flange, which is provided with, is used for the notch that current supply cable passes through, and is also set on flange
There is the cable pressing plate being placed on notch.
The utility model is further arranged to：The notch includes the inclination cell wall contradicted with cable, cable pressing plate bag
Include the attaching clamp being connected with flange and extend into the protection board in water housing, attaching clamp is two, and two attaching clamps
Between form cable entry port, connected between cable entry port and protection board by slanting connection wall.
The utility model is further arranged to：The stator sleeve uses stainless steel, and delivery chamber uses copper with flange
Material.
By using above-mentioned technical proposal, there is advantages below：Universal joint outer wall is pressed universal joint using holding circle
Contracting, prevents universal joint from causing to come off because moment of torsion is larger with nut；Adopted between stator sleeve and delivery chamber, between stator sleeve and flange
With threaded connection, it is easy to reduce the external diameter of stator sleeve, can also reduces the external diameter of pump；Cable pressing plate is formed using plastic injection, can
Prevent that friction is cut bad between cable and water inlet housing, is also prevented from cable downslide and gimbal friction；Stator sleeve uses stainless steel,
Delivery chamber and flange use copper material, appearance looks elegant and prevent from corroding, and the structural strength of stator sleeve is more preferable.
Brief description of the drawings
Fig. 1 is a kind of structural representation of immersible screw pump embodiment of the utility model.
Fig. 2 is the structural representation of cable pressing plate in a kind of immersible screw pump embodiment Fig. 1 of the utility model.
Embodiment
It is described further referring to figs. 1 to a kind of immersible screw pump embodiment of 2 pairs of the utility model.
One kind diving electric pump of screw rod 6, including machine barrel 1, water inlet housing 2, stator sleeve 3 and the delivery chamber 4 being sequentially connected, machine barrel
Stator rotating shaft 5 is provided with 1, screw rod 6 is provided with stator sleeve 3, is connected between stator sleeve 3 and water inlet housing 2 by flange 7, institute
State into water housing 2 is interior and be provided with universal joint 8, the both ends of universal joint 8 are equipped with the spiral shell for being respectively used to be connected with stator rotating shaft 5 and screw rod 6
Mother 9, the periphery wall of universal joint 8 is provided with holding circle 10.
Universal joint 8 uses quality of rubber materials, the equal embedded nut 9 in the both ends of universal joint 8, is respectively used to and stator rotating shaft 5 and screw rod 6
Connection, holding circle 10 can be that monoblock type is set in the outer wall of universal joint 8, or two are respectively sleeved at the both ends of universal joint 8
Periphery wall on, universal joint 8 is compressed, prevents universal joint 8 from causing to come off because moment of torsion is larger with nut 9, and influence use
Life-span.
It is connected through a screw thread between the stator sleeve 3 and flange 7, stator sleeve 3 and delivery chamber 4 are also by threaded connection, i.e.,
External screw thread is equipped with the outer wall at the both ends of stator sleeve 3, the external diameter of stator sleeve 3 can be reduced for connecting, during production, reduces material
Loss, reduces cost, can also reduce the external diameter of pump.
The flange 7, which is provided with, is used for the notch that current supply cable passes through, and the cable pressing plate being placed on notch is additionally provided with flange 7
11, notch includes the inclination cell wall 12 contradicted with cable, and cable pressing plate 11 includes the attaching clamp 13 being connected with flange 7 and prolonged
Extending into the protection board 14 in water housing 2, attaching clamp 13 is two, and cable entry port 15 is formed between two attaching clamps 13,
Connected between cable entry port 15 and protection board 14 by slanting connection wall 16.
Attaching clamp 13 is secured by bolts on flange 7, and slanting connection wall 16 is correspondingly arranged with tilting cell wall 12, makes electricity
The cable mounting hole of bending is formed between cable pressing plate 11 and notch, is easy to cable preferably to fix, prevent cable glide with it is universal
The friction of section 8, slanting connection wall 16 are obliquely installed with tilting cell wall 12, avoid camber excessive and damage cable, protection board 14 prolongs
Extend into the inwall of water housing 2, can prevent cable water inlet housing 2 between cut because of friction it is bad.
The stator sleeve 3 uses stainless steel, and delivery chamber 4 and flange 7 use copper material, appearance looks elegant and prevents corruption
Erosion, and the structural strength of stator sleeve 3 is more preferable.
Preferred embodiment of the present utility model is the foregoing is only, not limiting the utility model, the skill of this area
Art personnel carry out common variations and alternatives in the range of technical solutions of the utility model should all be included in guarantor of the present utility model
