Description
Technical field
The utility model is related to petroleum works technical fields, and in particular to a kind of packing box.
Background technology
In petroleum works field, exploitation oil be often used often annular space of the packing box between R a T into
Row sealing.However, existing packing box does not have automatic Regulation function, sealing function will be lost after packing abrasion, to cause
Well mouth of oil well oil leak.
Meanwhile in the actual production process, usually due to sucker rod quality problems itself, the work of sucker rod chronic fatigue etc.
Reason leads to rod parting, causes gas blowout accident.
Utility model content
The purpose of this utility model is to provide a kind of packing boxs.
To realize above-mentioned purpose of utility model, the utility model adopts the following technical solution：
A kind of packing box, including：
Blowout prevention set, pressure cap, pedestal, the pressure cap and pedestal are threadedly coupled with the both ends of blowout prevention set respectively；It is described anti-
Annular projection is equipped in spray set, the blowout prevention set of the annular projection side is surrounded with the pressure cap is formed with receiving sky
Between, it is formed with blowout prevention compartment in the blowout prevention set of the annular projection other side；
Packing, gland, the first spring being set in the accommodation space, the packing be set to the annular projection and
Between the gland, first spring, which supports, to be arranged between the pressure cap and the gland, by the packing to described
Annular projection side squeezes；
The blowout prevention set further includes the cylindrical groove being formed in the annular projection, the excessively described annular projection of the cylindrical groove
Mesoporous setting, second spring and catch are equipped in the cylindrical groove, the catch is located at the mesoporous side, and second spring is supported
Hold and be arranged between the cylindrical groove inner wall and the catch, with after rod parting takes out by the catch to the mesoporous
The other side is released, and the axis of the catch and the axis of the mesoporous are arranged at angle.
Compared with the existing technology, the utility model has technical effect that：
The utility model utilizes the first spring automatic compensation, and when packing is worn, packing can be closely pressed on by the first spring
On annular projection, it can continue to play sealing function, meanwhile, it is equipped with blowout prevention set, second spring occurs when blowout by catch
It releases, blocks annular projection mesoporous, play the role of preventing blowout.

A kind of structural schematic diagram of packing box in the utility model embodiment when Fig. 1 is sucker rod normal use；
A kind of structural schematic diagram of packing box in the utility model embodiment when Fig. 2 is rod parting taking-up；
Fig. 3 is the close-up schematic view at A in Fig. 2；
Fig. 4 be in Fig. 3 A-A to view.
Specific implementation mode
The utility model is described in detail below with reference to specific implementation mode shown in the drawings.But these embodiment party
Formula is not intended to limit the utility model, structure that those skilled in the art are made according to these embodiments, method or
Transformation functionally is all contained in the scope of protection of the utility model.
Refer to Fig. 1 to 4, a kind of packing box 100, including：
Blowout prevention set 1, pressure cap 2, pedestal 3, the pressure cap 2 and pedestal 3 are threadedly coupled with the both ends of blowout prevention set 1 respectively；
Annular projection 11 is equipped in the blowout prevention set 1, the blowout prevention set 1 of 11 side of the annular projection surrounds shape with the pressure cap 2
Cheng Youyi accommodation spaces, the blowout prevention of 11 other side of the annular projection, which covers in 1, is formed with blowout prevention compartment 16；
Packing 5, gland 6, the first spring 7 being set in the accommodation space, it is convex that the packing 5 is set to the ring-type
It rises between 11 and the gland 6, first spring 7, which supports, to be arranged between the pressure cap 2 and the gland 6, will be described
Packing 5 is squeezed to 11 side of the annular projection；
The blowout prevention set 1 further includes the cylindrical groove 12 being formed in the annular projection 11, and the cylindrical groove 12 is excessively described
The mesoporous 111 of annular projection 11 is arranged, and second spring 13 and catch 15 are equipped in the cylindrical groove 12, and the catch 15 is located at institute
111 side of mesoporous is stated, second spring 13, which supports, to be arranged between 12 inner wall of the cylindrical groove and the catch 15, in sucker rod
The catch 15 is released to 111 other side of the mesoporous after 200 disconnected de- taking-ups, the axis of the catch 15 and the mesoporous
111 axis is arranged at angle.
Cylindrical groove 12 is flat column, and activity space is provided for housing second spring 13 and catch 15, and for catch 15.
Catch 15 is stopped by sucker rod 200 when 200 normal use of sucker rod, is contained in the cylindrical groove 12 of 111 side of mesoporous, sucker rod
When 200 disconnected de- taking-up, second spring 13 releases catch 15 to 111 other side of mesoporous, seals mesoporous 111.
The pressure direction with mesoporous 111 of well liquid are axial parallel when blowout, and the axis and 111 axis of mesoporous of catch 15 are at angle
Setting, can increase 15 area of catch in mesoporous 111, help to reduce the pressure that 15 unit area of catch is born.
Blowout prevention compartment 16 works as a buffer, and when sucker rod 200 takes out, well liquid first fills blowout prevention compartment 16 again to mesoporous 111
Pressure can pop up for catch 15 and provide instantaneous buffer time.
Compared with the existing technology, the utility model has technical effect that：
The utility model utilizes the first spring automatic compensation, and when packing is worn, packing can be closely pressed on by the first spring
On annular projection, it can continue to play sealing function, meanwhile, it is equipped with blowout prevention set, second spring occurs when blowout by catch
It releases, blocks annular projection mesoporous, play the role of preventing blowout.
Finally it should be noted that：Embodiment of above is only to illustrate the technical solution of the utility model, rather than limits it
System；Although the utility model is described in detail with reference to aforementioned embodiments, those skilled in the art should
Understand：It can still modify to the technical solution recorded in aforementioned each embodiment, or special to which part technology
Sign carries out equivalent replacement；And these modifications or replacements, each reality of the utility model that it does not separate the essence of the corresponding technical solution
Apply the spirit and scope of mode technical solution.
