Abstract
The invention discloses a lengthened bolt. The lengthened bolt comprises a head portion, a screw, a first nut and a second nut, wherein the screw comprises a first part, a second part, a third part and a fourth part from top to bottom in sequence, the first part, the second part, the third part and the fourth part are fixedly connected with each other, the first part is a sliding rod, the upper portion of the first part is fixedly connected with the head portion, the second part is provided with first external threads, the first nut is provided with first internal threads matched with the first external threads, the third part is a sliding rod, the fourth part is provided with second external threads, and the second nut is provided with second internal threads matched with the second external threads. In this way, the lengthened bolt is more flexible to use, stronger in connect function and high in actual operation performance, and space occupied by the bolt and the cost of the bolt are reduced.
Description
Technical field
The present invention relates to mechanical part field, particularly relate to a kind of Lengthened bolt.
Background technique
Existing bolt is all generally for fastening two component, in the time having three or more component to be fixedly connected with by identical through hole, just must use Lengthened bolt, at this moment also require multiple component to be close to and to be fixedly connected with successively, otherwise, can only be fixed respectively connection by multiple different bolts.
Summary of the invention
The technical problem that the present invention mainly solves be to provide a kind of use more flexibly, operating characteristics that linkage function is stronger, actual is higher, saved the space that bolt takies, reduced the Lengthened bolt of bolt cost.
For solving the problems of the technologies described above, the invention provides a kind of Lengthened bolt, comprise: head, screw rod, the first nut and the second nut, described screw rod comprises the first portion being fixedly connected with from top to bottom successively, second portion, four parts of Part III and Part IV, described first portion is slide bar, the top of described first portion is fixedly connected with head, described second portion is provided with the first outside thread, described the first nut is provided with the first internal thread matching with described the first outside thread, described Part III is slide bar, described Part IV is provided with the second outside thread, described the second nut is provided with the second internal thread matching with described the second outside thread.
In a preferred embodiment of the present invention, described the first outside thread is identical with described the second outside thread.
In a preferred embodiment of the present invention, described the first outside thread is different from described the second outside thread.
In a preferred embodiment of the present invention, the length of described Part III is greater than the length of described first portion.
In a preferred embodiment of the present invention, the external diameter of described Part III is more than or equal to the external diameter of described first portion.
The invention has the beneficial effects as follows: Lengthened bolt of the present invention both can be used for connecting two component, can also be used for connecting multiple component, simultaneously, can also be used for connecting spaced coupled condition between multiple component, use more flexibly, linkage function is stronger, and actual operating characteristics is higher, save the space that bolt takies, reduced bolt cost.
Brief description of the drawings
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described 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, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation of Lengthened bolt one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, head; 2, the first nut; 3, the second nut; 4, first portion; 5, second portion; 51, the first outside thread; 6, Part III; 7, Part IV; 71, the second outside thread.
Embodiment
To the technological scheme in the embodiment of the present invention be clearly and completely described 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 all other embodiments that obtain 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 Lengthened bolt, comprise: head 1, screw rod, the first nut 2 and the second nut 3, described screw rod comprises the first portion 4 being fixedly connected with from top to bottom successively, second portion 5, 7 four parts of Part III 6 and Part IV, described first portion 4 is slide bar, the top of described first portion 4 is fixedly connected with head 1, described second portion 5 is provided with the first outside thread 51, described the first nut 2 is provided with the first internal thread (not marking in accompanying drawing) matching with described the first outside thread 51, described Part III 6 is slide bar, described Part IV 7 is provided with the second outside thread 71, described the second nut 3 is provided with the second internal thread matching with described the second outside thread 71.When the two or more component that connect are fixed arrangement together time successively, according to the total thickness that connects component under actual conditions, choice for use the first nut 2 or the second nut 3, and it is identical when connecting multiple component link positions, but between each component, have in the situation of certain distance, can use the first portion 4 of bolt, second portion 5 is connected multiple component with the first nut 2, simultaneously, use Part III 6, fastening other the component of Part IV 7 and the second nut 3, between multiple component like this, can there is according to actual needs certain interval, under present stage this pattern, can only complete by two or more bolts, and this bolt of the present invention uses a bolt to realize, its Placement variation, save the space that bolt takies, reduce bolt cost.
In addition, described the first outside thread 51 is identical with described the second outside thread 71, and such the first nut 2 and the second nut 3 can be general, use convenient.Certainly according to the needs of actual conditions, described the first outside thread 51 also can be different from described the second outside thread 71, and such the first nut 2 and the second nut 3 cannot be general, use more flexible.
In addition, the length of described Part III 6 is greater than the length of described first portion 4, can in fact regulate the interval connecting between component like this by the length of the first outside thread 51, and actual use value is higher, uses more flexible.
In addition, the external diameter of described Part III 6 is more than or equal to the external diameter of described first portion 4, facilitates like this installation and removal between component.
Be different from prior art, Lengthened bolt of the present invention both can be used for connecting two component, can also be used for connecting multiple component, meanwhile, can also be used for connecting spaced coupled condition between multiple component, use more flexible, linkage function is stronger, actual operating characteristics is higher, has saved the space that bolt takies, and has reduced bolt cost.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; 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.
