Abstract
The invention discloses a conducting bolt which comprises a bolt top, an outer bolt body and an inner bolt body. A first through hole is formed in the center of the outer bolt body, the inner bolt body is a cylinder, a second through hole is formed in the center of the inner bolt body, the bolt top is disc-shaped, the upper end of the outer bolt body is fixedly connected onto the bolt top, and the inner bolt body is in interference fit with the outer bolt body and is fixedly connected into the first through hole. Owing to the mode, the conducting bolt has the advantages of good conductivity, high connection strength and bearing capacity and low material cost.
Description
Technical field
The present invention relates to fastener areas, particularly relate to a kind of conducting bolt.
Background technique
Along with bolt application extensively, the effect of bolt has not only been confined to use as fastening piece, especially in the higher industry of some precision, because inner space is more and more less, a lot of bolts have good electric conductivity, and in order to meet the conducting function of bolt, the conducting bolt of present stage is all to use the material with electric conductivity to be made, and the use of these special materials has not only reduced the fastening performance of bolt, has also increased substantially the cost of material of bolt.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the conducting bolt that a kind of electric conductivity is better, join strength is high, bearing capacity is strong, the cost of material is low.
For solving the problems of the technologies described above, the invention provides a kind of conducting bolt, comprise: bolt top, outer bolt body and inner bolt body, the center of described outer bolt body is provided with the first through hole, described inner bolt body is cylindrical body, the center of described inner bolt body is provided with the second through hole, described bolt top arranges and is disc, the upper end of described outer bolt body is fixedly connected on described bolt top, described inner bolt body and described outer bolt body interference fit, and described inner bolt body is fixedly connected in described the first through hole.
In a preferred embodiment of the present invention, described the second through-hole diameter is at 3-10 millimeter.
In a preferred embodiment of the present invention, the lower end of described outer bolt body is provided with outside thread.
In a preferred embodiment of the present invention, described conducting bolt also comprises the nut matching with outer bolt body.
In a preferred embodiment of the present invention, described bolt top is provided with third through-hole, and the central axis of described the first through hole and the central axis of described third through-hole coincide.
The invention has the beneficial effects as follows: conducting bolt electric conductivity of the present invention is better, join strength is high, bearing capacity is strong, the cost of material is low.
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 conducting bolt one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, bolt top; 11, third through-hole; 2, outer bolt body; 21, the first through hole; 22, outside thread; 3, inner bolt body; 31, the second through hole; 4, 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 conducting bolt, comprise: bolt top 1, outer bolt body 2 and inner bolt body 3, the center of described outer bolt body 2 is provided with the first through hole 21, described inner bolt body 3 is cylindrical body, the center of described inner bolt body 3 is provided with the second through hole 31, and described bolt top 1 arranges and is disc, and the upper end of described outer bolt body 2 is fixedly connected on described bolt top 1, described inner bolt body 3 and described outer bolt body 2 interference fit, and described inner bolt body 3 is fixedly connected in described the first through hole 21.
In addition, described the second through hole 31 diameters are at 3-10 millimeter.According to the needs of real use state, can also in the second through hole 31, be placed with conductive wire increases the electric conductivity of conducting bolt.
In addition, the lower end of described outer bolt body 2 is provided with outside thread 22, has increased the field of employment of conducting bolt, and by outside thread 22 and the cooperation that is connected object, has also increased its join strength.
In addition, described conducting bolt also comprises the nut 4 matching with outer bolt body 2, same increase the field of employment of conducting bolt, and by outside thread 22 and the cooperation that is connected object, also increased its join strength.
In addition, described bolt top 1 is provided with third through-hole 11, the central axis of the central axis of described the first through hole 21 and described third through-hole 11 coincides, and like this according to the needs of real use state, can also in the second through hole 31, be placed with conductive wire increases the electric conductivity of conducting bolt.
Be different from prior art, conducting bolt electric conductivity of the present invention is better, join strength is high, bearing capacity is strong, the cost of material is low.
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.
