Abstract
The utility model discloses a cross-shaped hexagonal flange bolt which comprises a cross-shaped hexagonal head portion, a flange fixedly connected with the hexagonal head portion and a screw rod with an outer thread. The outer thread is arranged in the position, corresponding to a nut, of the tail end of the screw rod. The edge of the flange is coiled and folded towards one side of the screw rod to form a circle of concaved face filled with lubricants. The position, at the edge of the concaved face, on the screw rod is provided with a circle of protruding edge with the diameter equal to the outer diameter of the outer thread, and the protruding edge is coaxial with the screw rod. A segment of sealing groove without an outer thread is formed between the protruding edge and the outer thread, and the sealing groove is coated by a circle of sealing ring. The cross-shaped hexagonal flange bolt has the following advantages that due to the fact that the sealing ring is used, the requirement for sealing the flange face bolt can be met; the edge of the flange is bent into the concaved face, the concaved face is filled with the lubricants, and therefore when the bolt is fastened to a part, the lubricants can be contained in the concaved face, the contact faces between the flange and the part can be protected and lubricated for a long term, and rust is prevented; the cross-shaped hexagonal flange bolt is convenient to detach.
Description
Technical field
The utility model relates to a kind of bolt, is specially a kind ofly for a kind of cross hexagon flange bolt on automobile, belongs to five metals manufacturing technology field.
Background technique
Bolt, is one of modal mechanical parts, the cylindrical threaded fastening piece of adapted nut.Bolt: by head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, need coordinate with nut, for being fastenedly connected two parts with through hole.This Connecting format claims bolt to connect.As nut is screwed off from bolt, can make again these two parts separately, therefore bolt connects, be to belong to removably connect.
By the force way connecting, divide: point common and have articulation hole to use.By nose shape, divide: there is hexagon head, round end, square spigot, countersunk head etc.Wherein hexagon head is the most frequently used.
Bolt head with surmount remove twist face diameter the bolt of supporting surface flange face bolt.Hexagon flange bolt is by hexagon-head and flange plate (pad below hexagonal is fixed together with hexagonal) and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, need coordinate with nut, for being fastenedly connected two parts with through hole.This Connecting format claims bolt to connect.As nut is screwed off from bolt, have and can make these two parts separately, therefore bolt connects, be to belong to removably connect.
There is following defect in existing flange bolt:
1, in some local need to sealing, do not possess seal action, on automobile rearview mirror, need water-tight;
2, because the surface of contact of flange bolt and secure component is larger, the time has been grown, the surface of contact generation oxidation and rusting of flange plate and secure component, thus be difficult to dismounting; When therefore normal generation is with screwdriver demounting bolt, because exerting oneself compared with the situation of the destruction of senior general's cross hexagon.
Model utility content
The purpose of this utility model is for a kind of cross hexagon flange bolt is provided, to solve the problems referred to above of prior art.
The purpose of this utility model is achieved through the following technical solutions.
A kind of cross hexagon flange bolt, comprises cross hexagon head, with the fixing flange plate of hexagon-head with externally threaded screw rod; Described outside thread is arranged at the position that screw rod tail end is corresponding with nut; Described flange plate edge forms one to screw rod one side convolution and encloses the concave surface that is marked with oiling agent; On the screw rod of described concave surface edge, be provided with protruding stupefied identical with major diameter of external thread of a circle, protruding stupefied and screw coaxial; Between protruding stupefied and outside thread, be provided with one section without externally threaded seal groove, described seal groove is coated with a circle seal ring.
The edge of described concave surface is greater than protruding stupefied height to the distance of screw rod.
The external diameter of described seal ring equals externally threaded external diameter.
Described externally threaded tooth form is the one in V thread screw, square threaded form, trapezoidal thread and buttress thread form.
Footpath outside described in the utility model (large footpath) refers to and the imaginary cylinder diameter coinciding at the bottom of outside thread crest or internal thread tooth.The nominal diameter of screw thread is large footpath.Internal diameter (path) refers to at the bottom of outside thread tooth or the imaginary cylinder diameter that coincides of internal thread crest.
The utlity model has following beneficial effect:
1,, by the use of seal ring, can meet the demand that flange face bolt needs seal;
2, by the edge of flange is bent into concave surface, and inject oiling agent in concave surface, when bolton is on parts time, oiling agent can be housed in concave surface like this, protects for a long time and the surface of contact of lubricated flange and parts, prevents from getting rusty; Be convenient to dismounting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A portion structure for amplifying schematic diagram of Fig. 1;
