The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of oil sealing knot of the oil well pump of good seal performance
Structure.
The utility model to achieve the above object, using following technical scheme：The oil enveloping structure of oil well pump, including axis, oil
Envelope and babinet, axle position is in the axis hole of babinet, and the axis hole of babinet is in step-like, and oil-sealing sleeve is on axis and compresses at babinet axis hole
Step is equipped with circlip groove, auxiliary stopper seal groove and cone tank on axis successively, and oil sealing includes rubber section and compression ring, rubber section
Inner ring is equipped with auxiliary stopper sealing ring and taper ring, and auxiliary stopper sealing ring engages with auxiliary stopper seal groove, taper ring and cone
Shape slot engages, and one side of rubber section is equipped with pressing groove, and compression ring is inserted into pressing groove, and one end that rubber section is contacted with compression ring has
Taper, the other end compress the step at babinet axis hole, and rubber section outer ring is bonded with the axis hole of babinet, and engaging in circlip groove has gear
Circle, baffle ring pressure gear compression ring, in the trapezoidal of outer narrow inner width, the penetralia of taper ring is circular arc mistake in the section of auxiliary stopper sealing ring
It crosses.
Be additionally provided with seal groove on axis, in seal groove engaging have a rubber seal, rubber seal outer ring and babinet
Axis hole is bonded.
The section of rubber seal is rectangle.
The utility model has the beneficial effects that：The utility model compresses rubber section using compression ring, makes rubber section inner ring more
It is adjacent to axis, outer ring is more adjacent to the axis hole of babinet, and auxiliary stopper sealing ring and taper ring not only make more accurate positioning, but also enhance
Sealing effect, under the pressuring action of compression ring, the shape of auxiliary stopper sealing ring and taper ring further enhances sealing effect
Fruit.

Attached drawing in the utility model is all schematic diagram, and size and relative scale do not represent actual size；
It is described in detail with reference to attached drawing below with reference to the embodiments of the present invention.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in FIG. 1 to 3, the oil enveloping structure of oil well pump, including axis 5, oil sealing and babinet 1, axis 5 are located at the axis of babinet 1
The axis hole of Kong Zhong, babinet 1 are in step-like, and oil-sealing sleeve is on axis 5 and compresses the step at 1 axis hole of babinet, and gear is equipped with successively on axis 5
Ring recess 7, auxiliary stopper seal groove 8 and cone tank 9, oil sealing include rubber section 4 and compression ring 2, and 4 inner ring of rubber section is equipped with auxiliary and limits
Position sealing ring 12 and taper ring 13, auxiliary stopper sealing ring 12 engage with auxiliary stopper seal groove 8, taper ring 13 and cone tank 9
Engaging, 4 one sides of rubber section are equipped with pressing groove 11, and compression ring 2 is inserted into pressing groove 11, and rubber section 4 is contacted with compression ring 2
One end is tapered, and the other end compresses the step at 1 axis hole of babinet, and 4 outer ring of rubber section is bonded with the axis hole of babinet 1, in circlip groove 7
Engaging has baffle ring 3, and the pressure gear compression ring 2 of baffle ring 3, the section of auxiliary stopper sealing ring 12 is in trapezoidal, the taper ring 13 of outer narrow inner width
Penetralia be arc transition.
Be additionally provided with seal groove 10 on axis 5, in seal groove 10 engaging have a rubber seal 6,6 outer ring of rubber seal with
The axis hole of babinet 1 is bonded.
The section of rubber seal 6 is rectangle.
When the utility model is used, first rubber seal 6 will be packed into seal groove 10, then rubber section 4 is sleeved on axis
Axis 5 is inserted into the axis hole of babinet 1 by corresponding position on 5, and rubber section 4 is made to compress the step at 1 axis hole of babinet, will be compressed later
Ring 2 is inserted into pressing groove 11, and baffle ring 3 is loaded onto in circlip groove 7.Due to the pressuring action of compression ring 2,4 inner ring of rubber section is more
It is adjacent to axis 5, outer ring is more adjacent to the axis hole of babinet 1, and the shape of auxiliary stopper sealing ring 12 and taper ring 13 makes compression ring 2 insert
