[ Utility model ] content
The utility model discloses an aim at solving the problem among the prior art, provide a high strength jar body four paws combination bolt, the utility model discloses simple structure, reasonable in design, bolt overall structure intensity is high, and shock resistance is good, is difficult to appear becoming flexible, can keep the stability of connection for a long time.
In order to realize the above-mentioned purpose, the utility model provides a four-jaw combination bolt of high strength jar body, including spiral shell head, double-screw bolt, convex claw, nut and gasket, spiral shell head bottom center department is equipped with the double-screw bolt, the double-screw bolt still includes changeover portion and screw thread section, the bottom of changeover portion links to each other with the screw thread section, the changeover portion is equipped with a plurality of convex claws with the junction of spiral shell head, be equipped with the nut in the screw thread section, be equipped with the gasket between nut and the spiral shell head.
Preferably, the transition section is a regular hexagonal prism, and the length of the diagonal line of the transition section is the same as the diameter of the thread section.
Preferably, the number of the convex claws is 4, the convex claws are uniformly distributed in a circumferential shape, and the convex claws, the screw heads and the transition section are designed in an integrated manner.
Preferably, the nut is a hexagonal nut, and the gasket is provided with a contraction groove.
Preferably, the outer side of the screw head is provided with a protective sleeve, the protective sleeve is a mushroom-umbrella-shaped outer sleeve, and the inner wall of the protective sleeve is tightly attached to the outer wall of the screw head.
The utility model has the advantages that: the utility model divides the stud into the transition section of the regular hexagonal prism and two ends of the common thread section, so that the stud can bear larger impact force, and the stud is ensured not to be fractured in the transportation of the tank body; the friction force between the bolt main body and the connecting piece is increased and the possibility of loosening of bolt connection is reduced by arranging the plurality of convex claws and the gasket with the contraction groove; through the mode that sets up the protective sheath in the spiral shell head outside for the unable direct contact spiral shell head of atmospheric environment has reduced the corrosion rate of spiral shell head, has increased bolted connection's life.
[ description of the drawings ]
Fig. 1 is a schematic structural view of the four-jaw assembly bolt for a high-strength tank of the present invention.
In the figure: 1-screw head, 2-screw bolt, 20-transition section, 21-screw section, 3-convex claw, 4-nut, 5-gasket, 50-shrinkage groove and 6-protective sleeve.
[ detailed description ] embodiments
Referring to the drawings, the utility model relates to a four-jaw combination bolt of high strength jar body, including spiral shell head 1, double-screw bolt 2, protruding claw 3, nut 4 and gasket 5, 1 bottom center department of spiral shell head is equipped with double-screw bolt 2, double-screw bolt 2 still includes changeover portion 20 and screw thread section 21, the bottom of changeover portion 20 links to each other with screw thread section 21, the junction of changeover portion 20 and spiral shell head 1 is equipped with a plurality of protruding claws 3, be equipped with nut 4 on the screw thread section 21, be equipped with gasket 5 between nut 4 and the spiral shell head 1.
The transition section 20 is a regular hexagonal prism, and the length of the diagonal line of the transition section 20 is the same as the diameter of the threaded section 21.
The number of the convex claws 3 is 4, the convex claws 3 are uniformly distributed in a circumferential shape, and the convex claws 3, the screw head 1 and the transition section 20 are designed in an integrated manner.
The nut 4 is a hexagonal nut, and a contraction groove 50 is formed in the gasket 5.
Wherein, the spiral shell head 1 outside is equipped with protective sheath 6, protective sheath 6 is mushroom-shaped overcoat, the outer wall of spiral shell head 1 is hugged closely to the inner wall of protective sheath 6.
Compared with the prior art, the utility model divides the stud 2 into the transition section 20 of the regular hexagonal prism and the two ends of the common thread section 21, so that the stud 2 can bear larger impact force, and the stud 2 is ensured not to be fractured in the transportation of the tank body; by arranging a plurality of convex claws 3 and a gasket 5 with a contraction groove 50, the friction force between the bolt main body and the connecting piece is increased, and the possibility of loosening of bolt connection is reduced; through the mode that sets up protective sheath 6 in the spiral shell head 1 outside for the unable direct contact spiral shell head 1 of atmospheric environment has reduced spiral shell head 1's corrosion rate, has increased bolted connection's life.
The above-mentioned embodiment is right the utility model discloses an explanation, it is not right the utility model discloses a limited, any right the scheme after the simple transform of the utility model all belongs to the protection scope of the utility model.
