Abstract
The invention discloses a multifunctional novel threaded rod which comprises a nut, a first threaded rod body, a second threaded rod body and a third threaded rod body. The nut is fixedly connected to the upper end of the first threaded rod body; the lower end of the first threaded rod body, the second threaded rod body and the third threaded rod body are fixedly connected in sequence; a circular groove is formed in the upper end of the nut; an inner thread is arranged inside the groove; an outer thread matched with the inner thread is arranged at the lower end of the third threaded rod body. By means of the multifunctional novel threaded rod, a plurality of threaded rod bodies can be connected in an end-to-end mode; the production difficulty of the threaded rod is not increased, the effective length of the threaded rod is increased, the bearing torque of the multiple thread rod bodies is improved, the threaded rod is effectively prevented from being fractured, the using range is wider, and the using effect is better.
Description
Technical field
The present invention relates to five metals apparatus field, particularly relate to a kind of Multifucntional screw rod.
Background technique
Screw type outer surface is cut spiral fluted cylinder or is cut the circular cone of Conical Spiral Groove, existing screw rod, when for being connected and fixed two or more part, a connection hole is all use screw rod, therefore, length and the external diameter of screw rod need to match with the part be connected, and when be connected part between action radius longer time, the length of corresponding screw rod is also longer, like this, the production difficulty of screw rod increases, and screw rod also easily to rupture because length is oversize.
Summary of the invention
The technical problem that the present invention mainly solves be to provide a kind of increase screw rod effective length, improve the bearing torque of multiple screw rod, effectively avoid the fracture of screw rod, using scope is wider, the better Multifucntional screw rod of using effect.
For solving the problems of the technologies described above, the invention provides a kind of Multifucntional screw rod, comprise: nut, the first screw rod, the second screw rod and the 3rd screw rod, described nut is fixedly connected on the upper end of described first screw rod, the lower end of described first screw rod, described second screw rod and described 3rd screw rod are fixedly connected sequentially, the upper end of described nut is provided with a circular cell body, and the inside of described cell body is provided with internal thread, and the lower end of described 3rd screw rod is provided with the outside thread matched with described internal thread.
In a preferred embodiment of the present invention, the degree of depth of described cell body is greater than 1/3 of described nut height.
In a preferred embodiment of the present invention, the upper end external diameter of described second screw rod is greater than the lower end external diameter of described second screw rod, the smooth outer surface of described second screw rod.
In a preferred embodiment of the present invention, described 3rd screw rod is cylindric, and the external diameter of described 3rd screw rod is less than the external diameter of described first screw rod.
The invention has the beneficial effects as follows: multiple screw rod can join end to end by Multifucntional screw rod of the present invention, the production difficulty of screw rod can not be increased, increase the effective length of screw rod, improve the bearing torque of multiple screw rod, effectively avoid the fracture of screw rod, using scope is wider, and using effect is better.
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 Multifucntional 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 Multifucntional screw rod, comprise: nut 1, first screw rod 2, second screw rod 3 and the 3rd screw rod 4, described nut 1 is fixedly connected on the upper end of described first screw rod 2, the lower end of described first screw rod 2, described second screw rod 3 and described 3rd screw rod 4 are fixedly connected sequentially, the upper end of described nut 1 is provided with a circular cell body 11, the inside of described cell body 11 is provided with internal thread, and the lower end of described 3rd screw rod 4 is provided with the outside thread 41 matched with described internal thread.This screw rod namely can used aloned, also may multiple uses that join end to end, and more extensively, using effect is better for using scope.
Because internal thread and outside thread 41 can be used in combination, like this, when needing the action radius between the parts be connected longer, multiple screw rod can be used simultaneously, only needing the 3rd screw rod 4 of a screw rod to be connected with the nut 1 of another one screw rod, just can by multiple screw rod one by one be fixedly connected sequentially together, increase the effective length of screw rod, meanwhile, do not increase again the production difficulty of screw rod, do not reduce the bearing torque of screw rod, effectively avoid the fracture of screw rod.
The degree of depth of described cell body 11 is greater than 1/3 of described nut 1 height, and when the multiple screw rod of needs is used in conjunction with each other, the degree of depth of cell body 11 is greater than the degree of disturbing that 1/3 of described nut 1 height effectively can ensure multiple screw rod, ensures that multiple screw rod can not rupture.
The upper end external diameter of described second screw rod 3 is greater than the lower end external diameter of described second screw rod 3, the smooth outer surface of described second screw rod 3.
Described 3rd screw rod 4 is cylindric, and the external diameter of described 3rd screw rod 4 is less than the external diameter of described first screw rod 1.
Be different from prior art, multiple screw rod can join end to end by Multifucntional screw rod of the present invention, can not increase the production difficulty of screw rod, increase the effective length of screw rod, improve the bearing torque of multiple screw rod, effectively avoid the fracture of screw rod, using scope is wider, and using effect is better.
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.
