Abstract
The invention discloses a fishtail bolt, comprising a fishtail rod, a first nut, a screw and a second nut, wherein the fishtail rod is fixedly connected with the upper end of the screw, the end part of the fishtail rod is provided with a through hole, after being connected with the upper end of the screw, the first nut is connected below the fishtail rod, the upper part of the screw is a bare rod, the lower part of the screw is provided with external threads, the second nut is provided with internal threads, and the second nut is movably connected with the screw through mutual matching of the external threads and the internal threads. In this way, the fishtail rod and the screw of the fishtail bolt are fixedly connected, and the second nut and the screw are movably connected, so that connection between steel rails is more convenient, the use is more convenient, the connection effect is better, and the fastening effect is better.
Description
Technical field
The present invention relates to fastener areas, particularly relate to a kind of fishtail bolt.
Background technology
Fishtail bolt is mainly used in the track laying of metallurgy industry, coking industry, steel industry, and rail is connected fastening with rail joint, owing to being fastening between rail, so require comparatively strict.
Summary of the invention
The technical problem that the present invention mainly solves be to provide a kind of fastening effect better, use convenient fishtail bolt.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of fishtail bolt, comprise: fish tail bar, first nut, screw rod and the second nut, described fish tail bar is fixedly connected on the upper end of described screw rod, the end of described fish tail bar is provided with a through hole, the below of fish tail bar is connected to after described first nut is connected with the upper end of screw rod, the top of described screw rod is divided into polished rod, the lower part of described screw rod is provided with external screw thread, described second nut is provided with internal thread, described second nut is movably connected on described screw rod by external screw thread and cooperatively interacting of internal thread.
In a preferred embodiment of the present invention, described bolt also comprises pad, and described pad is movably connected in the top of the second nut.
In a preferred embodiment of the present invention, the external diameter of described pad is greater than the external diameter of described second nut.
In a preferred embodiment of the present invention, the external diameter of described first nut is less than the external diameter of described fish tail bar.
The invention has the beneficial effects as follows: fishtail bolt fish tail bar of the present invention is fixedly connected with screw rod, and the second nut is flexibly connected with screw rod, makes the connection between rail convenient, uses convenient, connect better effects if, fastening effect is better.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of fishtail bolt one of the present invention preferred embodiment.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of fishtail bolt, comprise: fish tail bar 1, first nut 2, screw rod 3 and the second nut 4, described fish tail bar 1 is fixedly connected on the upper end of described screw rod 3, the end of described fish tail bar 1 is provided with a through hole 11, the below of fish tail bar 1 is connected to after described first nut 2 is connected with the upper end of screw rod 3, the top of described screw rod 3 is divided into polished rod, the lower part of described screw rod 3 is provided with external screw thread 31, described second nut 4 is provided with internal thread, and described second nut 4 is movably connected on described screw rod 3 by external screw thread and cooperatively interacting of internal thread.
Described bolt also comprises pad 5, and described pad 5 is movably connected in the top of the second nut 4.
The external diameter of described pad 5 is greater than the external diameter of described second nut 4.
The external diameter of described first nut 2 is less than the external diameter of described fish tail bar 1.
Be different from prior art, fishtail bolt fish tail bar of the present invention is fixedly connected with screw rod, and the second nut is flexibly connected with screw rod, makes the connection between rail convenient, uses convenient, and connect better effects if, fastening effect is better.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
