Background
At present, a plurality of packing sealing polished rods are adopted by the oilfield wellhead polished rod sealing and wellhead protecting device, and when oil is pumped, the polished rods reciprocate up and down, and packing is easy to wear and needs to be replaced frequently. Because the packing is arranged in the packing box, when the packing needs to be replaced, an operator usually buckles the packing outwards by using a screwdriver or a small-diameter steel stick, which is difficult and dangerous, and the accident of breaking fingers often happens; particularly in cold winter, operators are labored to operate, and easily frosted by handles, so that the problem that the packing is difficult to replace in the wellhead polished rod sealing protection device of the oil field can be seen
Disclosure of Invention
The utility model provides a well head protector to solve the difficult problem of change packing that current polished rod is sealed and well head protection device exists.
The utility model discloses the technical scheme who takes is, including packing gland, packing box body, packing pad, packing, afterburning rod cover and packing connection nipple joint, wherein the lower part threaded connection of nipple joint upper portion and packing box body is connected to the packing, and in the packing box body was packed into to the packing, the packing top was arranged in to the packing pad, packing gland lower part and the upper portion threaded connection of packing box body, and packing gland bottom surface and packing top face compress tightly, two afterburning rod covers respectively with packing box body lower extreme welding.
The periphery of the upper part of the packing gland is provided with a reinforcing rod inserting hole.
The inner cavity of the packing box of the utility model is provided with a taper alpha.
The tapering alpha of packing box internal chamber is 1 ~ 2 degrees.
The quantity of packing is 4 ~ 6.
The quantity of packing is 4.
The utility model has the advantages of novel structure, tapering through packing box internal chamber area can be laborsaving when not hard up or tighten the packing box body, make the change that the packing can relax, adopt longer packing to connect short energy-conserving release the packing from the packing box body, just need not follow 2 internal hardnesses of packing box body and past having buckled outward, save time and be laborsaving, the injury occurence of failure of having avoided disconnected finger or handle frostbite has solved the problem that the change packing is difficult that current polished rod is sealed and well head protection device exists, the work efficiency is improved, the safety of production has been ensured.

Detailed Description
Example 1
The packing box comprises a packing gland 1, a packing box body 2, a packing pad 3, a packing 4, a stress application rod sleeve 5 and a packing connecting nipple 6, wherein the upper part of the packing connecting nipple 6 is in threaded connection with the lower part of the packing box body 2, the packing 4 is arranged in the packing box body 2, the packing pad 3 is arranged above the packing 4, the lower part of the packing gland 1 is in threaded connection with the upper part of the packing box body 2, the bottom surface of the packing gland 1 is tightly pressed against the upper surface of the packing pad 3, and the two stress application rod sleeves 5 are respectively welded with the lower end of the packing box body 2;
the periphery of the upper part of the packing gland 1 is provided with a stress application rod insertion hole 101;
the taper alpha of the inner cavity of the packing box body 2 is 1 degree;
the number of the packing 4 is 4.
Example 2
As shown in fig. 1 and 2, the packing device comprises a packing gland 1, a packing box body 2, a packing pad 3, a packing 4, a stress application rod sleeve 5 and a packing connecting nipple 6, wherein the upper part of the packing connecting nipple 6 is in threaded connection with the lower part of the packing box body 2, the packing 4 is arranged in the packing box body 2, the packing pad 3 is arranged above the packing 4, the lower part of the packing gland 1 is in threaded connection with the upper part of the packing box body 2, the bottom surface of the packing gland 1 is tightly pressed on the packing pad 3, and the two stress application rod sleeves 5 are respectively welded with the lower end of the packing box body 2;
the periphery of the upper part of the packing gland 1 is provided with a stress application rod insertion hole 101;
the taper alpha of the inner cavity of the packing box body 2 is 1 degree;
the number of the packing sets 4 is 5;
example 3
The packing box comprises a packing gland 1, a packing box body 2, a packing pad 3, a packing 4, a stress application rod sleeve 5 and a packing connecting nipple 6, wherein the upper part of the packing connecting nipple 6 is in threaded connection with the lower part of the packing box body 2, the packing 4 is arranged in the packing box body 2, the packing pad 3 is arranged above the packing 4, the lower part of the packing gland 1 is in threaded connection with the upper part of the packing box body 2, the bottom surface of the packing gland 1 is tightly pressed against the upper surface of the packing pad 3, and the two stress application rod sleeves 5 are respectively welded with the lower end of the packing box body 2;
