Abstract
The invention discloses a fastening bolt which comprises a head portion, a screw rod, a first nut and a second nut. The screw rod is provided with double-line outer threads which are the first outer thread and the second outer thread respectively, wherein the first outer thread and the second outer thread are crossed in a spaced mode. The upper portion of the screw rod is fixedly connected with the head portion, the first nut is provided with a first inner thread matched with the first outer thread, and the second nut is provided with a second inner thread matched with the second outer thread. By means of the method, the fastening bolt is provided with the double-line outer threads and can be used in cooperation with the nuts with different specifications, and two through holes in the head portion can be used for unscrewing and screwing the nuts. The occupied space is little, operation is convenient, the operation space is flexible, the application range is wide, and the use effect is good.
Description
Technical field
The present invention relates to bolt field, particularly relate to a kind of clamping bolt.
Background technique
Existing clamping bolt is all to be screwed on or screw off from screw rod by nut, mount and dismount component, this Placement, nut place must reserve larger space, carrys out rotating nut, particularly in the time that attended operation power is larger, also need by using the instruments such as spanner nut could to be screwed on or screws off from screw rod, operating space demand is larger, and existing bolt, a screw rod can only be used in combination with a kind of nut of specification, in actual use, has certain narrow limitation.
Summary of the invention
The technical problem that the present invention mainly solves be to provide a kind of take up room little, easy to operate, operating space flexibly, applied range, clamping bolt that using effect is good.
For solving the problems of the technologies described above, the invention provides a kind of clamping bolt, comprise: head, screw rod, the first nut and the second nut, described screw rod is provided with two-wire outside thread, described two-wire outside thread is respectively the first outside thread and the second outside thread, described the first outside thread intersects separately with described the second outside thread, the top of described screw rod is fixedly connected with head, described the first nut is provided with the first internal thread matching with described the first outside thread, and 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 head is arranged to hollow sphere, and described head center place is provided with first through hole.
In a preferred embodiment of the present invention, described head be also provided with one with perpendicular the second through hole of the first through hole.
In a preferred embodiment of the present invention, the diameter of described the first through hole is greater than the diameter of described the second through hole.
In a preferred embodiment of the present invention, described the first externally threaded pitch is less than described the second externally threaded pitch.
The invention has the beneficial effects as follows: clamping bolt of the present invention has two-wire outside thread, can be used in combination with the nut of different size, two through holes of head can be used for turning on and the nut of screwing on, take up room little, easy to operate, operating space is flexible, applied range, using effect is good.
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 clamping bolt one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, head; 11, the first through hole; 12, the second through hole; 2, screw rod; 21, the first outside thread; 22, the second outside thread; 3, the first nut; 4, the second nut.
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 clamping bolt, comprise: head 1, screw rod 2, the first nut 3 and the second nut 4, described screw rod 2 is provided with two-wire outside thread, described two-wire outside thread is respectively the first outside thread 21 and the second outside thread 22, described the first outside thread 21 intersects separately with described the second outside thread 22, the top of described screw rod 2 is fixedly connected with head 1, described the first nut 3 is provided with the first internal thread matching with described the first outside thread 21, and described the second nut 4 is provided with the second internal thread matching with described the second outside thread 22.
Owing to establishing and having plenty of double-start thread on screw rod 2, this screw rod 2 can be used in combination with two kinds of nuts, and using scope is more extensive, and using effect is better.
In addition, described head 1 is arranged to hollow sphere, and described head 1 center is provided with first through hole 11.Can use a straight-bar matching to screw on or screw off nut from the bottom of bolt by the first through hole 11, take up room less.
In addition, described head 1 be also provided with one with perpendicular the second through hole 12 of the first through hole 11.Same, can use equally a straight-bar matching to screw on or screw off nut from the bottom of bolt by the second through hole 12, take up room less, could be by bolton and needn't must operate from nut as existing bolt, operating space is flexible.
In addition, the diameter of described the first through hole 11 is greater than the diameter of described the second through hole 12.
In addition, the pitch of described the first outside thread 21 is less than the pitch of described the second outside thread 22.
Be different from prior art, clamping bolt of the present invention has two-wire outside thread, can be used in combination with the nut of different size, two through holes of head can be used for turning on and the nut of screwing on, and take up room little, easy to operate, operating space is flexible, applied range, and using effect is good.
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.
