Description
[technical field]
The utility model relates to the technical fields of the technical field of connector, especially bolt.
[background technique]
Bolt: machine components, the cylindrical threaded fastener of adapted nut are dimerous by head and screw rod
A kind of fastener need to cooperate with nut, and for being fastenedly connected two parts for having through-hole, this type of attachment claims bolt to connect
It connects, some special occasions need more demanding to bolt, need the leakproofness of bolt preferable, and bolt is quick detachable, can repeatedly make
With screw head is obviously easily found.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of bolt, the good airproof performance of bolt,
A word homalocephalus is arranged in screw head to turn with spanner cooperation, is hardly damaged, can repeatedly make for a long time by screw head longer Yi Faxian
With.
To achieve the above object, the utility model proposes a kind of bolt, including screw rod, screw head, connecting rod, the spiral shells
Bar surface coil is equipped with screw thread, and the screw rod upper end is equipped with connecting rod, and the connecting rod upper end is equipped with screw head, the spiral shell
Head is cylindrical type, and a word homalocephalus is equipped at the top of the screw head, and the diameter of the connecting rod is greater than the diameter of screw rod, screw head.
Preferably, being equipped with annular rib between the connecting rod upper end and screw head.
Preferably, the connecting rod outer ring is equipped with convex annular looping.
Preferably, the screw rod, screw head, connecting rod are an integral molding structure.
Preferably, the coaxial arrangement of the screw rod, screw head and connecting rod.
Preferably, the screw rod, screw head, connecting rod surface are equipped with plating antirust coat.
The utility model has the beneficial effects that the utility model is by will be arranged annular rib and annular protrusion in connecting rod
Circle, when bolt is tightened, connecting rod can be directly threaded into the counterbore to match, and convex annular looping can be enhanced connecting rod and sink
Connection between the hole wall of hole enhances leakproofness, and annular rib can limit bolt, and cooperates enhancing sealing with the upper end of counterbore
Property, screw head is arranged by connecting rod upper end, screw head is that oval column type is easily found, is arranged a word homalocephalus in screw head, and spanner can be with
It blocks a word homalocephalus and tightens bolt and unscrew, a word homalocephalus not rapid wear can be subjected to repeatedly turning.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
[Detailed description of the invention]

Fig. 2 is a kind of structural schematic diagram left view of bolt of the utility model.
In figure: 1- screw rod, 2- screw head, 3- connecting rod, 11- screw thread, mono- word homalocephalus of 21-, 31- annular rib, 32- convex annular
Looping.
[specific embodiment]
Refering to fig. 1 and Fig. 2, a kind of bolt of the utility model, including screw rod 1, screw head 2, connecting rod 3,1 table of screw rod
Face is arranged with screw thread 11, and 1 upper end of screw rod is equipped with connecting rod 3, and 3 upper end of connecting rod is equipped with screw head 2, described
Screw head 2 is cylindrical type, and a word homalocephalus 21 is equipped at the top of the screw head 2, and the diameter of the connecting rod 3 is greater than screw rod 1, screw head
2 diameter, is equipped with annular rib 31 between 3 upper end of connecting rod and screw head 2,3 outer ring of connecting rod is equipped with annular
Protrusion circle 32, the screw rod 1, screw head 2, connecting rod 3 are an integral molding structure, the screw rod 1, screw head 2 and connecting rod 3
Coaxial arrangement, the screw rod 1, screw head 2,3 surface of connecting rod are equipped with plating antirust coat.
Utility model works process:
A kind of bolt of the utility model during the work time, screw rod 1 is aligned at corresponding counterbore, by shfting wrench card
The firmly word homalocephalus 21 in screw head 2, rotary spanner tightens bolt, tightens rear connecting rod 3 and sinks to counterbore, the annular of connecting rod 3
Protrusion circle 32 can cooperate enhancing leakproofness with the hole wall of counterbore, and the annular rib 31 of 3 upper end of connecting rod and counterbore upper end cooperate,
Bolt is limited, and counterbore is sealed.
Above-described embodiment is the explanation to the utility model, is not the restriction to the utility model, and any pair of sheet is practical new
Scheme after type simple transformation belongs to the protection scope of the utility model.
