Abstract
The invention discloses a splicing type bolt which comprises a bolt head and a splicing screw rod. The bolt head is of a regular-hexagon-shaped stereoscopic structure. The splicing screw rod is connected to the center axis of the bolt head. A thread is arranged on the surface of the splicing screw rod. The splicing screw rod is detachably divided into two parts, one part of the splicing screw rod is connected with the bolt head, and the part of the splicing screw rod and the bolt head are integrally machined into a slot rod; a cylindrical groove is formed in the center axis of the slot rod, and a thread is formed in the inner surface of the groove; the other part of the splicing screw rod is a single protruding rod independently manufactured. The protruding rod is in a two-segment type and is formed by connecting two cylindrical structures with different diameters. The small-diameter segment is a convex shaft, the large-diameter segment is the screw rod, and threads are arranged on the surface of the cam shaft and on the surface of the screw rod. By means of the thread structures, the convex shaft on the protruding rod is rotationally screwed into the groove of the slot rod, and the convex shaft and the groove are in seamless splicing to form a longer splicing screw rod. In this way, the splicing type bolt is novel in structure and unique in use mode. The splicing bolt can be adjusted according to the length of the required screw rod, people can select the short screw rod or the spliced long bolt, practicality is good, and operation is convenient and easy.
Description
Technical field

Bolt is the one of mechanical parts, and the cylindrical threaded fastening piece of adapted nut, is made up of spiral shell head and screw rod, and need and nut screw connection, for being fastenedly connected two parts with through hole, at present, the spiro rod length of the bolt on market is fixing immutable.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of spliced bolt, can carry out choice for use to the length of screw rod, convenient and practical.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of spliced bolt, it is characterized in that, comprising: spiral shell head, spliced screw rod, described spiral shell head is regular hexagon stereochemical structure, the spliced screw rod described in the connection of central axis place of described spiral shell head; Described spliced screw surface is provided with screw thread, is removablely divided into two-part, and a part of with described spiral shell head is connected, the channel-shaped bar integrally processed, and described channel-shaped bar central axis place is provided with the hole slot of a cylindrical shape, and hole slot internal surface is provided with screw thread; Another part is the convex bar of the individuality be independently made; Described convex bar is two-part, and the cylindrical structure comprising two diameters different is formed by connecting, minor diameter be convex axle, large diameter is screw rod, and surface is provided with screw thread; Wherein, by worm structure, the convex axle on described convex bar can be rotated and be screwed in the hole slot of described grooved bar, both are seamless spliced, form a longer spliced screw rod.
In a preferred embodiment of the present invention, described spiral shell head and spliced screw rod material are round steel.
In a preferred embodiment of the present invention, described grooved bar race diameter is identical with the screw diameter of described convex bar.
In a preferred embodiment of the present invention, the inner ring hole slot diameter of described grooved bar is identical with the diameter of section of described convex bar epirelief axle.
In a preferred embodiment of the present invention, the grooved bar described in described spliced screw rod can only use, also uses after sliceable described convex bar.
The invention has the beneficial effects as follows: novel structure of the present invention, usage mode is unique, can regulate according to the length of required screw rod to this spliced bolt, and selects the screw rod compared with short status or bolt longer after splicing, practical, simply easy to operate.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological 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:
