Description
[technical field]
The utility model relates to the technical field of fastening piece, particularly the technical field of the special fixing bolt of a kind of rail.
[background technique]
Bolt is the shaft-like object of taking the lead of attached threaded cylinder, and the screwed cylinder in one end part is called stud, for nut screw connection, the other end is head, is called bolt head.Bolt is made of metal usually, and the bolt used at the special occasions such as electrical insulation or corrosion protection also has various non-metallic material.There is hexagon head, round end, square spigot, countersunk head etc.Wherein hexagon head is the most frequently used.General countersunk head is used in and requires to connect the smooth place not having projection, rear surface, because countersunk head may be screwed in part.Round end also can be screwed in part.The screwing force of square toes can more greatly, but size is very large.Some bolts do not have the polished rod of screw thread to run business into particular one, and are eel-like figure bolt.This bolt is conducive to the connection by variable force.Steel structure has special high-strength bolt, head can do bigger, and size also changes.
Widely, new purposes is also in continuous appearance, and the advantage of rail has a lot in the application of present bolt, the ability to bear of rail is large, and resistance is little, so how many some mining sites and factories all can build some rails, rail needs to use bolt in fixing process, and existing bolt easily loosens, fixing insecure, need and steel ring with the use of, install inconvenient, a kind of bolt of market demand, rail can be made fixing reliable, simultaneously easy for installation, simply.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes the special fixing bolt of a kind of rail, can fixed rail, and fixing reliable, be not easy to loosen, evenly bolt strained, be not easy to come off, easy for installation, efficiency of construction is high, and the life-span is longer simultaneously.
For achieving the above object, the utility model proposes the special fixing bolt of a kind of rail, comprise spiral shell head, screw rod, all defeat block and pressing plate, described spiral shell head is strip, the two ends semicircular in shape of spiral shell head, and the first side of spiral shell is provided with screw rod, described screw rod is provided with screw thread, screw rod overlaps to have and all defeats block, described block top of all defeating is provided with pressing plate, and described pressing plate is provided with elongated hole.
As preferably, described block of all defeating is hemispherical.
As preferably, the two ends of described pressing plate are provided with projection, and described projection is tapered.
As preferably, the thickness of described pressing plate is 2 ~ 8mm.
The beneficial effects of the utility model: the utility model is by by spiral shell head, screw rod, all defeat block and pressing plate is applied on rail bolt, can fixed rail, fixing reliable, be not easy to loosen, evenly bolt strained, allow to there is larger height difference, applying flexible, strong adaptability, be not easy to come off, easy for installation, efficiency is high, and the life-span is longer simultaneously.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.

Fig. 2 is the main pseudosection of the special fixing bolt of a kind of rail of the utility model;
Fig. 3 is the worm's eye view of spiral shell head;
Fig. 4 is the plan view of pressing plate.
In figure: 1-spiral shell head, 2-screw rod, 21-screw thread, 3-all defeat block, 4-pressing plate, 41-elongated hole.
[embodiment]
Consult Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the special fixing bolt of a kind of rail of the utility model, comprise spiral shell head 1, screw rod 2, all defeat block 3 and pressing plate 4, described spiral shell head 1 is strip, the two ends semicircular in shape of spiral shell head 1, and spiral shell head 1 side is provided with screw rod 2, described screw rod 2 is provided with screw thread 21, screw rod 2 overlaps to have and all defeats block 3, described block 3 top of all defeating is provided with pressing plate 4, and described pressing plate 4 is provided with elongated hole 41.Described block 3 of all defeating is in hemispherical.The two ends of described pressing plate 4 are provided with projection, and described projection is tapered.The thickness of described pressing plate 4 is 2 ~ 8mm.
Utility model works process:
The special fixing bolt of a kind of rail of the utility model in the course of the work, first screw rod 2 is inserted in screw, then one end of pressing plate 4 is pressed on rail, by the other end pressure of pressing plate 4 on the ground, ground and rail can have certain height difference, pressing plate 4 and the sphere-contact of all defeating on block 3.
The special fixing bolt of a kind of rail of the utility model, by by spiral shell head 1, screw rod 2, all defeat block 3 and pressing plate 4 is applied on rail bolt, can fixed rail, fixing reliable, be not easy to loosen, evenly bolt strained, allow to there is larger height difference, applying flexible, strong adaptability, is not easy to come off, easy for installation, efficiency is high, and the life-span is longer simultaneously.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
