Abstract
The invention discloses a conductive bolt. The conductive bolt 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 in a disk shape. The upper end of the outer bolt body is fixedly connected to the bolt top. The inner bolt body is in interference fit with the outer bolt body, and the inner bolt body is fixedly connected into the first through hole. In this way, the conductive bolt is good in conductivity, high in connection strength, high in bearing capacity and low in material cost.
Description
Technical field
The present invention relates to fastener areas, particularly relate to a kind of conducting bolt.
Background technology
Along with bolt application extensive, the effect of bolt has been not limited solely to use as securing member, particularly in the industry that some precision are higher, owing to 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 use the material with electric conductivity to be made, and the use of these special materials, not only reduce the fastening performance of bolt, the material cost of bolt is also greatly improved.
Summary of the invention
The technical problem that present invention mainly solves is to provide the conducting bolt that a kind of electric conductivity is better, bonding strength is high, bearing capacity is strong, the cost of material is low.
For solving above-mentioned technical problem, the present invention provides a kind of conducting bolt, including: 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 cylinder, the center of described inner bolt body is provided with the second through hole, described bolt top arranges in disk form, 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 first through hole.
In a preferred embodiment of the present invention, described second through-hole diameter is at 3 ~ 10 millimeters.
In a preferred embodiment of the present invention, the lower end of described outer bolt body is provided with external screw thread.
In a preferred embodiment of the present invention, described conducting bolt also includes and the nut of outer bolt mates.
In a preferred embodiment of the present invention, described bolt top is provided with third through-hole, the central axis of described first through hole and the central axis of described third through-hole and coincides.
The invention has the beneficial effects as follows: conducting bolt electric conductivity of the present invention is better, bonding strength is high, bearing capacity is strong, the cost of material is low.
Accompanying drawing explanation
Figure l is the structural representation of conducting bolt one preferred embodiment of the present invention.
In accompanying drawing: l, bolt top; 11, third through-hole; 2, outer bolt body; 21, the first through hole; 22, external screw thread; 3, inner bolt body; 31, the second through hole; 4, nut.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Refer to figure l, the embodiment of the present invention includes: a kind of conducting bolt, including: bolt top l, 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 cylinder, the center of described inner bolt body 3 is provided with the second through hole 31, described bolt top l arranges in disk form, the upper end of described outer bolt body 2 is fixedly connected on described bolt top l, described inner bolt body 3 and described outer bolt body 2 interference fit, and described inner bolt body 3 is fixedly connected in described first through hole 21.
Bolt top l and outer bolt body 2 adopt common common material to be made, do not improve the material cost of conducting bolt, and ensure that the bonding strength of conducting bolt, and inner bolt body 3 adopts the material with electric conductivity to be made, although slightly increasing the electric conductivity of conducting bolt, but the bonding strength of conducting bolt is not reduced, by extrusion process step, inner bolt body 3 is tightly fixed in inside first through hole 21 of outer bolt body 2, interference fit ensure that inner bolt body 3 and outer bolt body 2 constitute an entirety, ensure that the bonding strength of conducting bolt.
It addition, described second through hole 31 diameter is at 3 ~ 10 millimeters. Needs according to real use state, additionally it is possible to be placed with conductive wire in the second through hole 31 to increase the electric conductivity of conducting bolt.
It addition, the lower end of described outer bolt body 2 is provided with external screw thread 22, add the field of employment of conducting bolt, and coordinating by external screw thread 22 and attached article, too increase its bonding strength.
It addition, described conducting bolt also includes the nut 4 matched with outer bolt body 2, the same field of employment adding conducting bolt, and coordinating by external screw thread 22 and attached article, too increase its bonding strength.
Additionally, described bolt top l is provided with third through-hole 11, the described central axis of the first through hole 21 and the central axis of described third through-hole 11 coincide, so needs according to real use state, additionally it is possible to be placed with conductive wire in the second through hole 31 to increase the electric conductivity of conducting bolt.
Being different from prior art, conducting bolt electric conductivity of the present invention is better, bonding strength is high, bearing capacity is strong, the cost of material is low.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the present invention to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, all in like manner include in the scope of patent protection of the present invention.
