Abstract
The utility model relates to a kind of packing boxs that can be convenient for changing packing pad, belong to the device of oil field shaft mouth sealing polished rod.The lower part of box body is threadedly coupled with lower contact, and packing pad is located in box body and is placed in the top of lower contact, and the top of packing pad is contacted with pressure cap, which is threadedly coupled with the top of box body.Advantage is structure novel, and box body can compress packing pad, to realize sealing with backspin using Open architecture up and down, the pressure cap on top；It when replacing packing pad, will be revolved on the pressure cap on top, open pressure cap, then by box body along lower contact backspin, lower contact can eject packing pad, kept replacement packing convenient and efficient when padding, time and manpower are saved, convenient for operation.
Description
Technical field
The utility model belongs to the device of oil field shaft mouth sealing polished rod.
Background technique
Currently, oil field mostly uses greatly mechanical oil production model, drives roofbolt to pump by polished rod by pumping unit, band
Dynamic down-hole oil pump plunger pumps in pump barrel, and crude oil is adopted and is extracted into ground.This operation mode must be in well head
Position configures the device of a sealing polished rod, prevents well liquid from leaking and pollutes.Traditional packing kit packing pad is mounted on box body
It is interior, it can only plunge into, cannot be taken out from lower part from upper opening, lower part is also without jacking or unloading device, so in carousel
Root pad when, need manually one by one dig out come, more renew again later, it is time-consuming, arduously.
Summary of the invention
The utility model provides a kind of packing box that can be convenient for changing packing pad, to solve at present when replacing packing pad,
Existing time-consuming, laborious problem.
The technical scheme adopted by the utility model is that: the lower part of box body is threadedly coupled with lower contact, and packing pad is located at box body
Top that is interior and being placed in lower contact, the top of packing pad are contacted with pressure cap, which is threadedly coupled with the top of box body.
The box body is cylindrical shape, and middle part is smooth inner wall.
The outer diameter of the packing pad is connect with the internal diameter clearance fit of smooth inner wall in the middle part of box body.
The lower contact has polished rod through-hole.
The pressure cap has polished rod through-hole.
The packing is lined with polished rod through-hole.
The utility model has the advantages that structure novel, for box body using Open architecture up and down, the pressure cap on top can
With backspin, packing pad is compressed, to realize sealing；It when replacing packing pad, will be revolved on the pressure cap on top, open pressure cap, then by box
Body can eject packing pad along lower contact backspin, lower contact, make to replace convenient and efficient when packing pad, saving time and manpower, just
In operation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The lower part of box body 2 is threadedly coupled with lower contact 4, and packing pad 3 is located in box body 2 and is placed in the top of lower contact, disk
The top of root pad 3 is contacted with pressure cap 1, which is threadedly coupled with the top of box body 2；
The box body is cylindrical shape, and middle part is smooth inner wall；
The outer diameter of the packing pad is connect with the internal diameter clearance fit of smooth inner wall in the middle part of box body；
The lower contact has polished rod through-hole.
The pressure cap has polished rod through-hole.
The packing is lined with polished rod through-hole.
Working principle: polished rod is passed through from the polished rod through-hole of pressure cap, packing pad and lower contact, and box body uses up and down
The pressure cap of Open architecture, top can compress packing pad 3 with backspin, when screwing pressure cap 1, and packing pads 3 outer diameters in 2 inner wall of box body
Position-limiting action under, internal diameter can become smaller, to realize sealing；It when replacing packing pad, will be revolved on the pressure cap on top, open pressure cap 1,
Again by box body 2 along lower contact backspin, lower contact can eject packing pad, for replacing packing pad.
