Abstract
The utility model provides an antitheft packing box, belonging to a packing box for a wellhead in oil field. The packing box is provided with a packing box original cap the outside of which is sleeved with a protective cap; a check ring under the packing box original cap is fixed on the protective cap; a transverse sleeve is fixed outside the protective cap; a pressing cap is arranged in the sleeve through threads; an opening rod is sleeved in the pressing cap; and the convex head of the opening rod faces a vertical groove on the outside of the packing box original cap. When the antitheft packing box is opened, the opening rod is inserted into the pressing cap to screw the pressing cap into the sleeve, and the convex head enters the vertical groove of the packing box original cap, so that the packing box can be conveniently screwed down or loosened. After the construction is completed, the pressing cap is screwed out, the opening rod is taken out, and the pressing cap is screwed down into the sleeve, so outlaws turn the protective cap which only idles around the original cap and can not detach the packing box, and great economic loss caused by crude oil theft of the oil field can be effectively prevented.
Description
Technical field
The utility model provides a kind of oil field shaft mouth packing box, especially a kind of packing box that prevents that crude oil is stolen.
Background technology
At present, the used oil well packing box in oil field is a thread connection, is easy to be dismantled, and makes crude oil stolen, causes a large amount of economic losses.Therefore, it is very necessary to make original oil well packing box possess anti-theft feature.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of antitheft packing box is provided, and it is difficult for being disassembled, and is stolen effectively to prevent crude oil.
The utility model is to realize like this, antitheft packing box, it has the former cap of packing box, the former cap of packing box outside is set with helmet, have back-up ring to be fixed on the helmet below the former cap of packing box, horizontal sleeve pipe is fixed on the outside of helmet, and pressure cap is installed in the sleeve pipe by screw thread, all-or-nothing piece is sleeved in the pressure cap, and the plush copper on the all-or-nothing piece is towards the vertical slot in the former cap of the packing box outside.
Adopt the antitheft packing box of said structure, when opening packing box, all-or-nothing piece inserts in the pressure cap, screws in pressure cap in the sleeve pipe again and plush copper is entered in the vertical slot of the former cap of packing box, can tighten or unload loose packing box easily.The construction back-out pressure cap that finishes takes out all-or-nothing piece, pressure cap is screwed in the sleeve pipe tighten again, and the lawless person rotates helmet and can only can't dismantle packing box, thereby effectively prevent the stolen a large amount of economic losses that cause of crude oil around former cap idle running.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies concrete structure of the present utility model.
As shown in drawings, the antitheft packing box of the utility model, it has the former cap 1 of packing box, the former cap of packing box outside is set with helmet 2, have back-up ring 8 to be fixed on the helmet 2 below the former cap of packing box, horizontal sleeve pipe 3 is fixed on the outside of helmet 2, and pressure cap 5 is installed in the sleeve pipe 3 by screw thread, all-or-nothing piece 6 is sleeved in the pressure cap 5, and the plush copper 4 on the all-or-nothing piece 6 is towards the vertical slot 7 in the former cap of packing box 1 outside.
Obviously, on the packing box of the utility model, parts such as sleeve pipe, pressure cap, all-or-nothing piece can have symmetry to be installed in two covers on the helmet, the convenience of the application of force when rotating helmet to improve.
The former cap of packing box by screw thread be installed in wellhead assembly 9 above.When opening packing box, all-or-nothing piece inserts in the pressure cap, and pressure cap is screwed in the sleeve pipe, and make plush copper on the all-or-nothing piece enter the vertical slot of former cap, and the rotation pressure cap compresses plush copper, and this moment, helmet and former cap fused, rotate helmet and can drive former cap rotation, can tighten or unload loose packing box easily.Construction finishes pressure cap is screwed out, and takes out all-or-nothing piece, pressure cap is screwed in the sleeve pipe tighten again, rotates helmet this moment again, and helmet only can can't be dismantled packing box, thereby play antitheft effect around former cap idle running.
