Abstract
The utility model provides a water-proof bolt. The water-proof bolt comprises a nut, a screw and a bolt head arranged at the lower end of the screw, wherein the screw is arranged below the nut, threads are arranged on the outer edge of the screw, a groove is formed in one side of the nut, a drainage port is formed in the middle of the groove, and the cross section of the drainage port is rectangular. The water-proof bolt has the advantages that water accumulated on the bolt can be discharged from the groove due to the arrangement of the drainage port, deformation of the bolt caused by corrosion is avoided, the service life of the bolt is prolonged, and using cost of the bolt is saved.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly a kind of waterproof bolt.
Background technique
Bolt is by head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, need to cooperate with nut, be used for being fastenedly connected two with the part of through hole, this Connecting format claims bolt to connect, as nut is screwed off from bolt, having to make these two parts separately, is to belong to removably connect therefore bolt connects.In the rainy day, rainwater usually accumulates in the concave surface place of bolt, corrodes for a long time bolt in the past, and bolt can not normally be used, and causes the frequent bolt, the waste material.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of waterproof bolt, the setting of drain opening can be discharged from groove the water that accumulates on the bolt, prevents the bolt corrosion distortion, prolongs the working life of bolt, saves the cost that bolt uses.
The utility model provides a kind of waterproof bolt, described waterproof bolt comprises nut, screw rod, and the bolt head that is arranged on described screw rod lower end, described screw rod is arranged on described nut below, described screw rod outer rim is provided with screw thread, described nut one side is provided with groove, is provided with drain opening in the middle of the described groove, and the cross section of described drain opening is rectangular.The purpose of this utility model designs a kind of waterproof bolt, and the setting of drain opening can be discharged from groove the water that accumulates on the bolt, prevents the bolt corrosion distortion, prolongs the working life of bolt, saves the cost that bolt uses, and is a kind of desirable bolt.
The utility model discloses a kind of a kind of improvement of waterproof bolt, the length of described screw rod is the 40%-65% of bolt total length.The length of the utility model screw rod is that the bolt total length is long, and the waste material does not have fastening effect, and the length of screw rod is that the bolt total length is 60% after tested, good fixing effect.
The purpose of this utility model designs a kind of waterproof bolt, and the setting of drain opening can be discharged from groove the water that accumulates on the bolt, prevents the bolt corrosion distortion, prolongs the working life of bolt, saves the cost that bolt uses, and is a kind of desirable bolt.
