Abstract
The utility model discloses a bolt, its screw rod include pole portion and bolt head, characterized by: the first downwardly extending of bolt forms pole portion, pole portion surface is equipped with the screw thread, the screw tooth form is 30, bolt head is equipped with the ring packing strip with the edge of the lower surface that pole portion is connected. Area of contact is big between this bolt and the cast aluminium spare, transversely gos deep into adversary's piece more, and the fastening effect is better, and sealed effect is stronger.
Description
Technical field
The utility model relates to a kind of bolt.
Background technique
Bolt is as a kind of fastening piece connected for object, be widely used on various apparatus, in use the counterbore of bolt head upper surface easily produces hydrops, do not get rid of the working life that can affect bolt head for a long time, general bolt in use needs separately to overlap pad to play seal action simultaneously, takes time and effort.
Model utility content
In view of the deficiency that background technique exists, technical problem to be solved in the utility model is to provide that a kind of structure is simple, cost is lower, fastening effect good and the bolt of long service life.
The utility model takes following technological scheme: a kind of bolt, its screw rod comprises bar portion and bolt head, described bolt head extends to form bar portion downwards, described bar portion outer surface is provided with screw thread, described thread profile is 30 °, and described bolt head is provided with annular sealing strip with the edge of the lower surface that bar portion is connected.
The upper surface of described bolt head is provided with the screw-threaded counterbore coaxial with bar portion, described bolt head upper surface is provided with four rhones symmetrical between two, described rhone is laterally inclined to bolt head, described rhone one end is docked with screw-threaded counterbore, the other end extends to bolt head side, described bolt head side is provided with drip, and described drip docks with rhone.
In the utility model, this bolt arrangement is simple, and in bar portion, the worm tooth of screw thread is 30 °, makes area of contact between this bolt and aluminum casting large, laterally more go deep into opponent's part, fastening effect is better, and the edge of the lower surface of described bolt head is provided with annular sealing strip, just can ensure sealing during use without the need to another shimming, described bolt upper surface is provided with rhone, in time the hydrops in counterbore can be discharged, prevent bolt head from being corroded by hydrops, improve the working life of bolt.
