The purpose of this utility model is at having the problems referred to above that easily stolen phenomenon of packing box and the disclosed technology of CN2243529Y exist now, propose a kind of simple in structure, pumpingh well well head multifunctional burglary-resistant packing box easy to use, as to have multistage antitheft, oil pipe exhaust air and test pressure function.
The technical scheme of this utility model is:
Pumpingh well well head multifunctional burglary-resistant packing box is by upper cover body 1, sleeve pipe 2 and place packing box assembly in the sleeve pipe 2 etc. to form.Sleeve pipe 2 is the metal sleeves that have internal thread, and its top is threaded with upper cartridge body 1, and lower internal thread is connected with the well head oil tube external thread, and inside is provided with the packing box assembly.The box body 4 of described packing box assembly is that Lower Half has externally threaded cylinder, and with sleeve pipe 2 internal thread rotation cooperate, the bottom inside face periphery of box body 4 is provided with boss, the top perimeter of box body 4 is uniform-distribution with 2-8 symmetrical notch and cooperates with the groove bolt 14 of special tool 13, and is provided with internal thread at first half inner surface.Every blocking 5 is a hollow circular flat board; insert and stop in the box body 4 and with the boss of box body 4 bottoms and cooperate; place polished rod protector 11 and packing body 10 every the top of blocking 5; by on wear externally threaded pressure cap cylindraceous 9 and box body 4 the internal thread rotation cooperate 10 crush seals of packing body; the top perimeter of pressure cap 9 is uniform-distribution with the notch similar to box body 4, uses the special tool similar to special tool 13 to act on the notch of pressure cap 9.Described special tool 13 is the open slots that are axially arranged with greater than polished rod 8 diameters, and an end radially is provided with circular hole, inserts afterburning handle 12, and the other end is provided with the groove bolt 14 of box body 4 equal numbers and cooperates with the notch of box body 4 (pressure cap 9).
This pumpingh well well head multifunctional burglary-resistant packing box also can be done following improvement.
Be uniform-distribution with screw 6 more than 2 in the junction horizontal direction of upper cover body 1 and sleeve pipe 2, fix by " fourth " font special tool 15 that cooperates with bolt by corner bolt in special-purpose; Perhaps fixing by " fourth " font special tool 16 of positive and negative pair of screw bolt and cooperation with it.
Radially be provided with a pressure gauge connection 7 in the middle and upper part of sleeve pipe 2.
The beneficial effect of this utility model:
Simple in structure, easy to use, in installation and operation process, need to use special tool to finish, have the antitheft effect of multilayer.Make things convenient for the discharging of depositing crude oil in oil well pressure measurement and the oil pipe simultaneously.
Description of drawings:
Fig. 1 is a vertical section structure schematic diagram of the present utility model.Wherein 1 is upper cover body, the 2nd, and sleeve pipe, the 3rd, antitheft steel ring, the 4th, the box body of packing assembly, the 5th, every blocking, the 6th, screw, the 7th, pressure gauge connection, the 8th, sucker rod, the 9th, pressure cap, the 10th, packing body, the 11st, polished rod protector.
Fig. 2 is the schematic diagram of the special tool 13 that is used with the utility model.
Fig. 3 is A---the A cross sectional representation of the special tool 13 that is used with the utility model.
Fig. 4 is the cross sectional representation of the special tool 15 that is used with the utility model.
Fig. 5 is the cross sectional representation of the special tool 16 that is used with the utility model.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, at first sleeve pipe 2 is inserted in polished rod, fastening with oil well oil conduit by being threaded, and the seam weldering is dead; Then every block 5, polished rod protector 11, packing body 10 insert in the box body 4 successively, pressure cap 9 external screw threads are formed the packing box assembly by fitting into box body 4 with the rotation of box body 4 internal threads, integral body is inserted in polished rod 8; With the box body 4 of special tool 13 rotation packing boxs, the bottom that the packing box assembly is moved to sleeve pipe 2 that cooperates of the external screw thread by box body 4 bottoms and the internal thread of sleeve pipe 2.Again antitheft steel ring 3 is inserted in the top that polished rod 8 places box body 4, with the groove covering of box body 4.
Upper cover body 1 is inserted in polished rod 8, by the top closure of connecting thread with sleeve pipe 2.
In order to strengthen antitheft effect, the connection of thread at upper cover body 1 and sleeve pipe 2 radially is provided with 2---the circular hole 6 and the silk hole of 8 correspondences, and interior corner bolt is fixing upper cover body 1 and sleeve pipe 2 with special tool 15; Also available positive and negative pair of screw bolt was fixed on upper cover body 1 on the sleeve pipe 2 with cooperating of special tool 16.By above two kinds of forms, can prevent effectively that upper cover body 1 from illegally opening, have certain antitheft effect.
