The top, the end of cylinder has been threadably secured a lower contact, and the lower section of described lower contact and oil well mouth connect；Outward
The inside of cylinder, its top and upper end cover contact site be fixed with a back-up ring, and the lower section of back-up ring is film fixed plate,
It is sealed film below film fixed plate, is film location-plate below described sealed film, film location-plate
Lower section is fixed with a sealed film and a film location-plate again；Described outer barrel, urceolus with under connect
Head contact site is fixed with a back-up ring, and the top of back-up ring is film fixed plate, and the top of film fixed plate is close
Sealing sheet, described sealed film is arranged above film location-plate, and the top of film location-plate is fixed with one again
Sealed film and a film location-plate；The inside of urceolus, the cavity of position, intermediate portion is liquid collecting cavity, urceolus
Connecting on sidewall and have a short tube, described short tube and liquid collecting cavity communicate, and the outer end of short tube connects a ball valve,
The outside of ball valve connects a union elbow.
The external diameter of described back-up ring and film fixed plate and sealed film and film location-plate and outer tube inner wall close-fitting.
On described urceolus, before and after it, both sides are respectively welded and are fixed with a handle, on the upper end cover above urceolus,
It is fixed with two handles with same welding manner.
The center of described upper end cover and back-up ring and film fixed plate and sealed film and film location-plate all adds
Work has through hole.
The beneficial effects of the utility model: this utility model passes through to use two sections formula to seal at outer barrel,
At sucker rod and oil pumping rod centering device through two sections sealed film, all can there is sucker rod fitted seal film
Do regular seal, effectively solve the problem that oil pumping rod centering device irregularly seals, because of sealed film and urceolus
Inwall fits tightly, and when playing sucker rod, sealed film can wipe the dead wax of the dead oil on sucker rod and centralizer off,
Effectively prevent oil wax from leaking, it is achieved that ground avoiding wax eliminating function, reach to avoid environmental pollution, environmental protection and energy saving
Purpose.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described through.As shown in drawings, a kind of sucker rod is certainly
Sealing wax scraping apparatus, it includes a urceolus 1, and the top of urceolus 1 has been threadably secured a upper end cover 2,
The top, the end of urceolus 1 has been threadably secured a lower contact 3, the lower section of described lower contact 3 and oil well mouth
11 connect；The inside of urceolus 1, its top and upper end cover 2 contact site are fixed with a back-up ring 7, back-up ring 7
Lower section be film fixed plate 8, be sealed film 9 below film fixed plate 8, described sealed film 9 times
Side is film location-plate 10, and the lower section of film location-plate 10 is fixed with a sealed film 9 and a glue again
Sheet location-plate 10；Urceolus 1 is internal, and urceolus 1 and lower contact 3 contact site are fixed with a back-up ring 7, back-up ring
The top of 7 is film fixed plate 8, and the top of film fixed plate 8 is sealed film 9, described sealed film 9
Being arranged above film location-plate 10, the top of film location-plate 10 is fixed with a sealed film 9 and one again
