Abstract
The utility model provides a novel bolt which comprises a bolt cap and a bolt rod. The novel bolt further comprises a reinforcing portion which is arranged between the bolt cap and the bolt rod and used for fixing an object in clamping mode, the area of a cross section of the reinforcing portion is larger than the area of a cross section of the bolt rod, and the cross section of the reinforcing portion is in the shape of a polygon. Due to the fact that the reinforcing portion is arranged between the bolt cap and the bolt rod, connection strength and rigidity of the novel bolt are effectively improved. Meanwhile, the reinforcing portion is used for fixing the object which needs fastening in clamping mode, and therefore the novel bolt can be conveniently screwed up.
Description
Technical field
The utility model relates to a kind of fastening connection piece, and specifically a kind of bus connects the Novel bolt of usefulness.
Background technique
The nuts of existing plain bolt generally all is the shapes such as hexagon head, square spigot, countersunk head, and these bolts are used very extensive, use also very convenient.
Chinese patent ZL200820169508.4 discloses the bolt that a kind of nuts is cambered surface, and nuts is arranged to cambered surface, is applicable to the fixture with arc surface of privileged sites or occasion.The use occasion in arc surface is mainly considered in this design, and does not consider the problems such as join strength.
Need bolt to come connection bus in the prior art, because the quality of bus is larger, the bolt of connection bus need to possess certain strength, and existing general bolt can't be directly used in the connection of bus.
The model utility content
For this reason, to be solved in the utility model is that existing bolt join strength is not high, can not be directly used in the problem that bus connects, and a kind of Novel bolt with high join strength is provided.
The utility model solves the problems of the technologies described above the technological scheme that adopts:
A kind of Novel bolt is provided, comprises nuts and bolt shank, also comprise the reinforcing part that is arranged between described nuts and the described bolt shank, the cross-section area of described reinforcing part is greater than the cross-section area of described bolt shank; And the shape of cross section of described reinforcing part is polygonal.
The shape of cross section of described reinforcing part is regular polygon.
The height of described reinforcing part is greater than or equal to the radius of described bolt shank, and less than the length of described bolt shank.
Described nuts have guarantee between the adjacent electrical equipment safe distance predetermined altitude.
Described nuts comprises the directly cylindrical body that links to each other with described reinforcing part and the spherical crown that links to each other with described cylindrical body, the axis of the described spherical crown cross section center of circle and described cylindrical center line and described bolt shank is located on the same line, and described cylindrical body bottom surface radius is greater than the radius of described bolt shank.
Also comprise the outermost one deck resin layer that consists of described bolt.
Described resin layer is zinc coat.
Technique scheme of the present utility model has the following advantages compared to existing technology:
Between described nuts and the described bolt shank reinforcing part is set, and the shape of cross section of reinforcing part is polygonal, reinforcing part has stiffening rib at side face, effectively raises the rigidity of join strength and bolt part.And,, conveniently tight a bolt to needing the fixing of fastening piece by reinforcing section.
Described nuts have guarantee between the adjacent electrical equipment safe distance predetermined altitude, guaranteed that the safety between the adjacent electrical equipment arranges.
The outermost of described nuts is cambered surface, can effectively avoid point discharge.
Described Novel bolt outermost surface also forms one deck resin layer, has strengthened anticorrosion effect.
Description of drawings
For content of the present utility model is more likely to be clearly understood, the below is described in further detail the utility model, wherein according to specific embodiment of the utility model also by reference to the accompanying drawings
Fig. 1 is the plan view of Novel bolt embodiment schematic diagram of the present utility model;
Fig. 2 is the right elevation of Novel bolt embodiment schematic diagram of the present utility model.
Reference character is expressed as among the figure: 1-nuts, 2-bolt shank, 21-screw section, 3-reinforcing part, 11-spherical crown, 12-cylindrical body.
Embodiment
Below in conjunction with the drawings and specific embodiments Novel bolt of the present utility model is described further:
Shown in Fig. 1-2, be an embodiment's of the utility model bolt arrangement schematic diagram, it comprises nuts 1 and bolt shank 2, and is arranged on the reinforcing part 3 between described nuts 1 and the described bolt shank 2, wherein, the cross-section area of described reinforcing part 3 is greater than the cross-section area of described bolt shank 2; And the shape of cross section of described reinforcing part 3 is square, be that described reinforcing part 3 is cuboid, the height of cuboid consists of the stiffening rib of described reinforcing part 3 simultaneously, can obtain better stiffening effect, by reinforcing section to needing the fixing of fastening piece, easily to bolt tightening; And, described reinforcing part 3 tall and big in the radius of described bolt shank 2, and less than the length of described bolt shank 2; Described nuts 1 comprises the directly cylindrical body 12 that links to each other with described reinforcing part 3 and the spherical crown 11 that links to each other with described cylindrical body 12, the center line of the described spherical crown 11 cross section centers of circle and described cylindrical body 12 and the axis of described bolt shank 2 are located on the same line, and described cylindrical body 12 bottom surface radiuses are greater than the radius of described bolt shank 2; The height of described nuts 1 is the height sum of height and the described spherical crown 11 of described cylindrical body 12, and it has predetermined altitude, and the safe distance that this equals between the adjacent electrical equipment highly at least guarantees that the safety between the adjacent electrical equipment arranges; The outer spherical surface of described spherical crown 11 consists of the part outer surface of described nuts 1, than the nuts setting that corner angle are arranged, can effectively avoid point discharge, is suitable for connection bus and uses.The outer surface of described bolt shank 2 forms and connects with screw section 21; At the outermost surface of described bolt, namely the outermost surface of described nuts 1, reinforcing part 3 and bolt shank 2 also forms one deck zinc coat (not shown), gets rusty to prevent bolt.
As another embodiment of the present utility model, bolt of the present utility model can arrange isolation layer as required as the outermost surface of bolt, can obtain better insulation effect.
Obviously, above-described embodiment only is for example clearly is described, and is not the restriction to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And the apparent variation of being extended out thus or change still are among the protection domain of the present utility model.
