Problems solved by technology
Disposable protective wires need to be removed one by one on the rig floor when the oil casing goes downhole, which is not only laborious but also time-consuming
Especially the protective wire on the male thread is easily deformed and damaged when bumped, which makes it even more difficult to disassemble.
Because the wrench at the notch protrudes the outer diameter of the wire, the quick protection wire is often scratched and damaged when dragging the oil casing, and it is also laborious to move the wrench

The invention relates to an equipment part, in particular to a quick disassembly and assembly screw protector for an oil casing. According to the technical scheme, the quick disassembly and assembly screw protector comprises an outer cylinder, an upper cover, two wrenches, a spring, two split screw protectors and two fixing pin shafts, the two fixing pin shafts are fixedly installed on an annularbottom plate of the outer cylinder side by side, the two split screw protectors are arranged on the two fixing pin shafts in a sleeving manner respectively to form rotating connection, and guide pinsare arranged on the split screw protectors; wrenching handles and bosses are arranged on the wrenches, the wrenching handles of the two wrenches are arranged adjacently, and the bosses of the two wrenches are connected through the spring; each wrench is provided with two oblong holes which respectively sleeve the corresponding fixed pin shaft and the corresponding guide pin; and the upper cover and the outer cylinder are mounted together to package the split screw protectors and the wrenches inside. The outer diameter of the screw protector is not provided with an opening or protruding part, the wrenches can be moved by two fingers to adjust the inner diameter of the screw protector, and the screw protector can be quickly disassembled and assembled on a well site in a time-saving and labor-saving manner.
Description
technical field [0001] The invention relates to an equipment component, in particular to a quick disassembly and assembly protection wire for an oil casing. Background technique [0002] The two ends of the oil casing and casing used in the oil field are respectively male and female threads, which are easy to cause damage to the male threads during transportation, handling and running the oil and casing. The protective wire is to protect the threads of the oil and casing. There are several types of protective wires currently in use, one is a disposable protective wire made of metal or non-metal when the oil casing is shipped from the factory. In addition, there is also a fast protective wire compounded by rubber and metal. This protective wire is slotted in the axial direction. The size of the notch can be adjusted by rotating the wrench connected to both ends of the notch, thereby changing the diameter of the protective wire to achieve fast speed. Disassemble the wire guar...
