Abstract
The utility model discloses a screw rod, including the screw rod body and transport screw thread and the binding thread of setting on the screw rod body, carry screw thread and binding thread crisscross the setting on the screw rod body each other, screw rod body one end is provided with the inlet port, inlet port edge screw rod axon is to setting up and 20mm is lacked than screw rod body length degree to length, the fastening thread bottom communicate with each other with the inlet port. In this way, the utility model discloses screw rod has the link bit and transmits two kinds of functions, during the use, can the exclusive use one of them plant function, also can two kinds of functions use simultaneously, carry laborsavingly, it is firm to fix a position.
Description
Technical field
The utility model relates to fastening piece, particularly relates to a kind of screw rod.
Background technique
Screw rod is one of a kind of fastening piece for removably connecting commonly used in machinery.Screw rod of the prior art in use, needs by larger external force afterburning to screw rod, then by screw rod is threaded into device interior, is connected by the component of two products.Although usage requirement can be met, when using, compare effort and function singleness.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of screw rod, and have and connect and transmission two kinds of functions, during use, namely can be used alone wherein a kind of function, and also can two kinds of functions use, carry laborsaving, it is firm to locate simultaneously.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of screw rod, the conveying screw thread comprising screw body and be arranged in screw body and binding thread, described conveying screw thread and binding thread is interlaced is arranged in screw body, described screw body one end is provided with inlet hole, described inlet hole is axially arranged and length 20mm shorter in screw body length along screw body, communicates bottom described binding thread with inlet hole.
In the utility model preferred embodiments, described conveying screw thread comprises left sea whelk, ball and right sea whelk, and described ball is arranged in the middle of left sea whelk and right sea whelk.
In the utility model preferred embodiments, described screw body circumferential surface is provided with helical pore, described helical pore is connected with binding thread.
In the utility model preferred embodiments, the spacing between described conveying screw thread and binding thread is 15mm.
In the utility model preferred embodiments, described screw body end is also provided with attachment hole.
The beneficial effects of the utility model are: a kind of screw rod of the utility model, and have and connect and transmission two kinds of functions, during use, namely can be used alone wherein a kind of function, and also can two kinds of functions use, carry laborsaving, it is firm to locate simultaneously.
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 screw rod one of the present utility model preferred embodiment.
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 screw rod, the conveying screw thread 2 comprising screw body 1 and be arranged in screw body 1 and binding thread 3, described conveying screw thread 2 and binding thread 3 is interlaced is arranged in screw body 1, described screw body 1 one end is provided with inlet hole 4, described inlet hole 4 is axially arranged and length 20mm shorter in screw body 1 length along screw body 1, communicates bottom described binding thread 3 with inlet hole 4.
Further, described conveying screw thread 2 comprises left sea whelk 2-1, ball 2-2 and right sea whelk 2-3, and described ball 2-2 is arranged in the middle of left sea whelk 2-1 and right sea whelk 2-3, when screw rod is applied in external force, conveying screw thread 2 utilizes the feature of its ball 2-2, does not need great external force just can move forward.
Further, described screw body 1 circumferential surface is provided with helical pore (not shown), described helical pore (not shown) is connected with binding thread 3.
In above-mentioned, when screw rod is used as conveyor worm, utilize the feature with ball 2-2 on conveying screw thread 2, its conveying is reliably laborsaving, when screw rod needs to be fastenedly connected, first utilized by screw rod conveying screw thread to move to commitment positions, then liquid or gas punching press are carried out to inlet hole 4, binding thread 3 produces expansion because of pressure, is then fastenedly connected with other component.
Further, the spacing between described conveying screw thread 2 and binding thread 3 is 15mm.
Further, described screw body 1 end is also provided with attachment hole 5, and attachment hole 5 can install other force application device, facilitates screw action.
The beneficial effects of the utility model are: a kind of screw rod of the utility model, and have and connect and transmission two kinds of functions, during use, namely can be used alone wherein a kind of function, and also can two kinds of functions use, carry laborsaving, it is firm to locate simultaneously.
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.
