In this way, the utility model discloses novel structure, using -way is unique, can adjust this concatenation formula bolt according to the length of required screw rod, and select the longer bolt of screw rod or concatenation back of short state, and the practicality is strong, and convenient operation is simple.
Description
Technical field
The utility model relates to fixed component field, particularly relates to a kind of spliced bolt.
Background technique
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.
Model utility content
The technical problem that the utility model 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 utility model 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 the utility model preferred embodiment, described spiral shell head and spliced screw rod material are round steel.
In the utility model preferred embodiment, described grooved bar race diameter is identical with the screw diameter of described convex bar.
In the utility model preferred embodiment, the inner ring hole slot diameter of described grooved bar is identical with the diameter of section of described convex bar epirelief axle.
In the utility model preferred embodiment, the grooved bar described in described spliced screw rod can only use, also uses after sliceable described convex bar.
The beneficial effects of the utility model are: the utility model novel structure, 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 utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, 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 a kind of spliced bolt one of the utility model preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, spiral shell head; 2, spliced screw rod; 3, channel-shaped bar; 301, hole slot; 4, convex bar; 401, convex axle; 402, screw rod.
Embodiment
Be clearly and completely described to the technological scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model is embodiment comprise:
A kind of spliced bolt, it is characterized in that, comprising: spiral shell head 1, spliced screw rod 2, described spiral shell head 1 is regular hexagon stereochemical structure, the spliced screw rod 2 described in the connection of central axis place of described spiral shell head 1; Described spliced screw rod 2 surface is provided with screw thread, removablely be divided into two-part, a part of with described spiral shell head 1 is connected, the channel-shaped bar 3 integrally processed, described channel-shaped bar 3 central axis place is provided with the hole slot 301 of a cylindrical shape, and hole slot 301 internal surface is provided with screw thread; Another part is the convex bar 4 of the individuality be independently made; Described convex bar 4 is two-part, and the cylindrical structure comprising two diameters different is formed by connecting, minor diameter be convex axle 401, large diameter is screw rod 402, and surface is provided with screw thread; Wherein, by worm structure, the convex axle 401 on described convex bar 4 can be rotated and be screwed in the hole slot 301 of described grooved bar 3, both are seamless spliced, form a longer spliced screw rod 2.
Be different from prior art.
In another embodiment, described spiral shell head 1 is round steel, material aboundresources with spliced screw rod 2 material, and processing technique is skillful, and cost is low.
In another embodiment, described grooved bar 3 race diameter is identical with screw rod 402 diameter of described convex bar 4, after both are spliced into one, can form a seamless link, the screw rod that diameter is consistent.
In another embodiment, inner ring hole slot 301 diameter of described grooved bar 3 is identical with the diameter of section of described convex bar 4 epirelief axle 401, and convex axle 401 just can rotate and be screwed in hole slot 301.
In another embodiment, the grooved bar 3 described in described spliced screw rod 2 can only use, also uses after sliceable described convex bar 4.
The utility model novel structure, 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.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description 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 utility model.
