Technical field
The utility model relates to a kind of technical field of mechanical equipment, and more particularly, it relates to a kind of deep-well pump motor.
Background technique
Deep-well pump is primarily of the pump housing and deep-well pump motor composition, deep-well pump motor is operationally for the pump housing provides power, from but the pump housing work normally, at present in order to stable electrical engine housing and the fixing of protecgulum adopt the motor (application number: thread connecting mode 201420499342.8) on deep-well pump usually, and be generally arranged in the deep-well of below hundreds of rice, and the delivery pipe that deep-well pump is generally manufactured by iron and steel hangs in well, owing to installing trouble deep-well pump except unloading down when damaging maintenance or do not use for a long time, the deep-well pump most of the time is immersed in well under normal circumstances, and current connecting primarily of the second screw, 3rd screw of side insertion plays the role of positioning, and owing to being immersed in well for a long time, and also directly contact with water, cause the easy corrosion of screw thread on the second screw and the 3rd screw surface, thus cause protecgulum and electric machine casing to depart from.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of stable connection, easily deep-well pump motor.
For achieving the above object, the utility model provides following technological scheme: a kind of deep-well pump motor, comprise electric machine casing, described electric machine casing one end is provided with protecgulum, described protecgulum is provided with the positive stop lug boss coordinated with electric machine casing grafting, described positive stop lug boss end is provided with spacing hole, described positive stop lug boss side is provided with the fixed hole communicated with spacing hole, position-limitting pin is provided with in described spacing hole, set screw is provided with in described fixed hole, described position-limitting pin side is provided with the tapped hole be threaded for set screw, described electric machine casing side is provided with the grafting through hole inserted for set screw.
Preferably, supplementary card connection mechanism is provided with between described electric machine casing and positive stop lug boss.
Preferably, described supplementary card connection mechanism comprises fixing salient point, and described fixing salient point is wholely set on positive stop lug boss sidewall, and described electric machine casing inwall is provided with the buckling groove for fixing salient point clamping.
Preferably, described buckling groove is bar shaped, and described electric machine casing inwall is also provided with the connecting groove slipping into buckling groove for fixing salient point.
Preferably, described position-limitting pin is provided with retaining washer.
Compared with prior art, the beneficial effects of the utility model are: electric machine casing four is on protecgulum, thus positive stop lug boss inserts in electric machine casing, make positive stop lug boss push electric machine casing to coordinate, again position-limitting pin is inserted in spacing hole, again set screw is stretched into grafting through hole successively, in fixed hole, set screw is made to be threaded in tapped hole, position-limitting pin is connected with set screw, thus the weight of electric machine casing acts on set screw when deployed, instead of act on screw thread, and the integrated carrying ability of set screw is greater than the bearing capacity of screw thread, and the entirety of set screw is also not easy to be corroded completely, thus effectively raise the life-span of use.

Embodiment
Referring to figs. 1 through Fig. 4, the utility model deep-well pump motor embodiment is described further.
A kind of deep-well pump motor, comprise electric machine casing 1, described electric machine casing 1 one end is provided with protecgulum 2, described protecgulum 2 is provided with the positive stop lug boss 21 coordinated with electric machine casing 1 grafting, described positive stop lug boss 21 end is provided with spacing hole 211, described positive stop lug boss 21 side is provided with the fixed hole 212 communicated with spacing hole 211, position-limitting pin 3 is provided with in described spacing hole 211, set screw 4 is provided with in described fixed hole 212, described position-limitting pin 3 side is provided with the tapped hole 31 be threaded for set screw 4, described electric machine casing 1 side is provided with the grafting through hole 11 inserted for set screw 4, electric machine casing 1 four is on protecgulum 2, thus positive stop lug boss 21 inserts in electric machine casing 1, make positive stop lug boss 21 push electric machine casing 1 to coordinate, again position-limitting pin 3 is inserted in spacing hole 211, again set screw 4 is stretched into grafting through hole 11 successively, in fixed hole 212, set screw 4 is made to be threaded in tapped hole 31, position-limitting pin 3 is connected with set screw 4, thus the weight of electric machine casing 1 acts on set screw 4 when deployed, instead of act on screw thread, and the integrated carrying ability of set screw 4 is greater than the bearing capacity of screw thread, and the entirety of set screw 4 is also not easy to be corroded completely, thus effectively raise the life-span of use.
Be provided with supplementary card connection mechanism between described electric machine casing 1 and positive stop lug boss 21, supplementary card connection mechanism provides extra join strength.
Described supplementary card connection mechanism comprises fixing salient point 213, described fixing salient point 213 is wholely set on positive stop lug boss 21 sidewall, described electric machine casing 1 inwall is provided with the buckling groove 12 for fixing salient point 213 clamping, when electric machine casing 1 coordinates with positive stop lug boss 21, fixing salient point 213 snaps in buckling groove 12, thus electric machine casing 1 can be made effectively to be fixed with coordinating of buckling groove 12 by fixing salient point 213 with spacing block set, thus when position-limitting pin 3 departs from set screw 4, also extra fixed effect can be had, and the strength decreased when position-limitting pin 3 is connected with set screw 4, improve working life.
Described buckling groove 12 is in bar shaped, described electric machine casing 1 inwall is also provided with the connecting groove 13 slipping into buckling groove 12 for fixing salient point 213, when mounted motor housing 1, first fixing salient point 213 slips in buckling groove 12 along connecting groove 13, fixing salient point 213 slides along buckling groove 12 again, thus fixed hole 212 is alignd with grafting through hole 11, then set screw 4 insertion is coordinated with position-limitting pin 3, can installation be completed, thus time install more convenient.
Described position-limitting pin 3 is provided with retaining washer 5, and retaining washer 5 is the elastic force that position-limitting pin 3 improves pretension, thus time position-limitting pin 3 connect more firm, avoid position-limitting pin 3 to loosen.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
