In a preferred embodiment of the present invention, the right-hand member of described the second screw rod is provided with second through hole, and the internal diameter of described the second through hole is identical with the internal diameter of described the first through hole.
In a preferred embodiment of the present invention, described composite bolt comprises two the first nuts, and described two the first nuts are connected with the right-hand member of the second screw rod with the upper end of the first screw rod respectively.
In a preferred embodiment of the present invention, the upper end of described the first screw rod is provided with the first outside thread, and described the first nut is provided with the first internal thread matching with described the first outside thread.
In a preferred embodiment of the present invention, the right-hand member of described the second screw rod is provided with the second outside thread, and described the second outside thread is identical with described the first outside thread.
In a preferred embodiment of the present invention, the two ends of described second body of bolt are all provided with the 3rd outside thread, and described the second nut is provided with the second internal thread matching with described the 3rd outside thread.
The invention has the beneficial effects as follows: composite bolt fastening strength of the present invention is high, fastening effective, conserve space, fastening bearing capacity are strong.
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 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 skills, 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 composite bolt one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, the first nut; 21, the first screw rod; 22, the second screw rod; 23, the first through hole; 24, the second through hole; 25, the first outside thread; 26, the second outside thread; 3, second body of bolt; 31, the 3rd outside thread; 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, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skills, 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 composite bolt, comprise: two the first nuts 1, first body of bolt, second body of bolt 3 and two the second nuts 4, described first body of bolt is arranged to L-type, described first body of bolt comprises the first screw rod 21 and the second screw rod 22, described the first screw rod 21 is mutually vertical with the second screw rod 22, and the lower end of described the first screw rod 21 is fixedly connected with the left end of described the second screw rod 22, the upper end of described the first screw rod 21 is provided with first through hole 23, the external diameter of described the first screw rod 21 is greater than the external diameter of described second body of bolt 3, described second body of bolt 3 is dismountable to be connected in described the first through hole 23, described the first nut 1 is in mating connection with described first body of bolt, described the second nut 4 is in mating connection with described second body of bolt 3.By first body of bolt and second body of bolt 3 of a L-type, this composite bolt can be used for fixing not fastening between the parts on same straight line of two, three, even more fixed position, and its fastening strength is high, fastening effective, conserve space, fastening bearing capacity are strong.
In addition, the right-hand member of described the second screw rod 22 is provided with second through hole 24, and the internal diameter of described the second through hole 24 is identical with the internal diameter of described the first through hole 23.The needs that use according to reality, also can be connected in described the second through hole 24 dismountable second body of bolt 3, have increased the using scope of composite bolt.
