Description
Technical field
The utility model is related to petroleum works technical field, and in particular to a kind of rod packing box.
Background technology
Packing box is frequently used at petroleum works field, exploitation oil to enter the annular space between R a T
Row sealing.However, existing packing box does not have automatic Regulation function, sealing function will be lost after packing abrasion, so as to cause
Well mouth of oil well oil leak.
Meanwhile, in actual production process, usually due to sucker rod quality problems itself, the work of sucker rod chronic fatigue etc.
Reason causes rod parting, causes gas blowout accident.
Utility model content
The purpose of this utility model is to provide a kind of rod packing box.
To realize above-mentioned utility model purpose, the utility model is adopted the following technical scheme that：
A kind of rod packing box, including：
Blowout prevention set, pressure cap, base, the pressure cap and base are threadedly coupled respectively with the two ends of blowout prevention set；It is described anti-
Annular projection is provided with spray set, the blowout prevention set and the pressure cap of the annular projection side surround and be formed with receiving sky
Between, it is formed with blowout prevention compartment in the blowout prevention set of the annular projection opposite side；
Packing, gland, the spring being arranged in the receiving space, the packing is arranged at the annular projection and described
Between gland, the spring is supported and is arranged between the pressure cap and the gland, by the packing to the annular projection
Side extrudes；
Interior is provided with some balls of string between the blowout prevention, and the mesopore inwall of the annular projection is provided with some barbs.
Used as the further improved technical scheme of the utility model, interior is additionally provided with prerotation vane between the blowout prevention, with well
The ball of string is oriented at the mesopore of the annular projection during spray.
It is of the present utility model to have technical effect that relative to prior art：
The utility model utilizes spring automatic compensation, and when packing weares and teares, packing can be closely pressed on spring annular projection
On so as to can continue to play sealing function, meanwhile, blowout prevention compartment is provided with, a ball of string is rushed at annular projection when there is blowout
Mesopore and by barbs hold a, ball of string accumulates in compacting at mesopore and blocks mesopore, plays a part of to prevent blowout.
Description of the drawings
Fig. 1 is a kind of structural representation of rod packing box in the utility model embodiment；
Fig. 2 is the close-up schematic view in Fig. 1 at A.

Annular projection 11 is provided with the blowout prevention set 1, the blowout prevention set 1 of the side of the annular projection 11 is 2-in-1 with the pressure cap to enclose shape
Cheng Youyi receiving spaces, in the blowout prevention set 1 of the opposite side of the annular projection 11 blowout prevention compartment 12 is formed with；
Packing 5, gland 6, the spring 7 being arranged in the receiving space, the packing 5 is arranged at the annular projection 11
And the gland 6 between, the spring 7 is supported and is arranged between the pressure cap 2 and the gland 6, by the packing 5 to institute
State the extruding of the side of annular projection 11；
Some balls of string 8 are provided with the blowout prevention compartment 12, the mesopore inwall of the annular projection 11 is provided with some barbs
9。
Further, prerotation vane 10 is additionally provided with the blowout prevention compartment 12, it is described to be oriented to the ball of string 8 in blowout
At the mesopore of annular projection 11.Prerotation vane 10 is in funnel-form, and larger opening is towards the side of base 3, less opening alignment ring
The mesopore of shape projection 11.
It is of the present utility model to have technical effect that relative to prior art：
The utility model utilizes the automatic compensation of spring 7, and when packing 5 weares and teares, packing 5 can be closely pressed on ring-type by spring 7
On raised 11 so as to can continue to play sealing function, meanwhile, blowout prevention compartment 12 is provided with, a ball of string 8 is rushed at ring when there is blowout
The mesopore of shape projection 11 is simultaneously hooked by barb 9, and a ball of string 8 accumulates in compacting at mesopore and blocks mesopore, and playing prevents the work of blowout
With.
Finally it should be noted that：Embodiment of above is only illustrating the technical solution of the utility model, rather than it is limited
System；Although being described in detail to the utility model with reference to aforementioned embodiments, one of ordinary skill in the art should
