Abstract
The utility model relates to an auxiliary structure of a main stud suitable for a pressure container, in particular to a joint structure of the main stud and a nut. The utility model provides an improved main stud and nut connecting part structure, aiming at solving the problem that a main stud and a nut are difficult to disassemble due to the fact that the connecting part of the main stud and the nut is easy to rust or corrode. The structure of the joint of the main stud and the nut solves the problem that the joint of the main stud and the nut is easy to rust or corrode, so that the main stud and the nut are difficult to disassemble.
Description
Technical Field
The utility model relates to an auxiliary structure of a main stud suitable for a pressure container, in particular to a joint structure of the main stud and a nut.
Background
At present, in the design and manufacture of a pressure vessel, a large number of main studs and nuts are required to realize the fixed connection between components. During the use, main double-screw bolt is twisted in the screwed hole of part, then twists the nut admittedly in the front end of main double-screw bolt, when pressure vessel reprocesses, need unscrew the nut, takes off the nut from the front end of main double-screw bolt the rear and can accomplish the dismantlement of part, nevertheless the condition emergence that corrosion or corruption often can appear in main double-screw bolt and nut junction to lead to main double-screw bolt and nut to dismantle the difficulty, influence work efficiency.
Disclosure of Invention
The utility model provides an improved structure of a joint of a main stud and a nut, aiming at solving the problem that the joint of the main stud and the nut is difficult to disassemble due to the fact that the joint is easy to rust or corrode.
The utility model is realized by adopting the following technical scheme: main double-screw bolt and nut junction structure, including main double-screw bolt and twist in the nut of main double-screw bolt front end, dustcoat in the staving form protection casing of main double-screw bolt front end and be used for connecting the bolt of protection casing and main double-screw bolt, the open end of protection casing flushes with the bottom of nut, the terminal surface of main double-screw bolt front end is equipped with the screw hole coaxial with main double-screw bolt, open at the bottom of the bucket of protection casing has first hole, the bolt passes first hole and twists in the screw hole. During the use, the protection casing covers in the front end of main double-screw bolt and the open end of protection casing flushes with the bottom of nut for main double-screw bolt is covered in the protection casing with the nut junction, adopts the bolt to make protection casing and main double-screw bolt fixed simultaneously, and such structure has avoided main double-screw bolt and nut junction to expose, has reduced the main double-screw bolt and the condition emergence that the nut junction appears the corrosion or corrodes, has solved the problem that main double-screw bolt and nut dismantle the difficulty to a certain extent.
The beneficial effects produced by the utility model are as follows: the structure of the joint of the main stud and the nut solves the problem that the joint of the main stud and the nut is easy to rust or corrode, so that the main stud and the nut are difficult to disassemble, and has the advantages of simple structure and installation, high efficiency and good quality.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a schematic structural diagram of the main stud.
In the figure: 1-main stud, 2-nut, 3-protective cover, 4-threaded hole, 5-first hole, 6-bolt.
Detailed Description
Main double-screw bolt and nut junction structure, including main double-screw bolt 1 and twist in the nut 2 of main double-screw bolt 1 front end, the dustcoat is in the staving form protection casing 3 of the front end of main double-screw bolt 1 and be used for connecting the bolt 6 of protection casing 3 and main double-screw bolt 1, the open end of protection casing 3 flushes with the bottom of nut 2, the terminal surface of main double-screw bolt 1 front end is equipped with the screw hole 4 coaxial with main double-screw bolt 1, open at the barrel head of protection casing 3 has first hole 5, bolt 6 passes first hole 5 and twists in screw hole 4. During the use, the protection casing 3 covers in the front end of main double-screw bolt 1 and the open end of protection casing 3 flushes with the bottom of nut 2 for main double-screw bolt 1 is covered in protection casing 3 with the nut 2 junction, adopts bolt 6 to make protection casing 3 fixed with main double-screw bolt 1 simultaneously, and such structure has avoided main double-screw bolt 1 and nut 2 junction to expose, has reduced the condition emergence that corrosion or corruption appear in main double-screw bolt 1 and nut 2 junction, has solved the problem that main double-screw bolt 1 and nut 2 dismantle the difficulty to a certain extent.
When the concrete implementation, protection casing 3 is cylindric, and the structure is standardized.
