Abstract
The invention discloses a screw which comprises a screw body, and conveying threads and fastening threads arranged on the screw body, wherein the conveying threads and fastening threads are arranged on the screw body in a stagger manner; an air inlet is formed in one end of the screw body; the air inlet is formed in the axial direction of the screw body and is 20 mm shorter than the screw body; the bottoms of the fastening threads are communicated with the air inlet. Through the adoption of the scheme, the screw has the connecting and conveying functions; during the use of the screw, only one function can be independently used, and both the functions can also be used at the same time; the conveying is labor-saving, and the positioning is firm.
Description
Technical field
The present invention relates to fastening piece, particularly relate 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.
Summary of the invention
The technical problem that the present invention 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 present invention 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 present invention's 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 present invention's preferred embodiments, described screw body circumferential surface is provided with helical pore, described helical pore is connected with binding thread.
In the present invention's preferred embodiments, the spacing between described conveying screw thread and binding thread is 15mm.
In the present invention's preferred embodiments, described screw body end is also provided with attachment hole.
The invention has the beneficial effects as follows: a kind of screw rod of the present invention, 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 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 screw rod one of the present invention preferred embodiment.
Embodiment
Be clearly and completely described to the technological 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 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 invention has the beneficial effects as follows: a kind of screw rod of the present invention, 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 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.
