Abstract

The utility model discloses a kind of weld bolts, and there is the cylinder body of rod, the outer circle of the cylinder body of rod to be equipped with screw thread, it is characterised in that:The top of the cylinder body of rod is equipped with welding boss, and the outside diameter for welding boss is more than the outside diameter of the cylinder body of rod, and the top end surface for welding boss is equipped with column point boss in middle position, and the maximum outside diameter and height of the column point boss are no more than 1.5mm.The utility model can more preferably carry out the spot-welded of bolt, and the high fastness of intensity of spot-welded is good, ensure that connection is reliable.

Description

Weld bolt
Technical field
The utility model is related to a kind of fastener products, and in particular to a kind of weld bolt can be used for spot-welded.
Background technology
To keep connection type more simple, some products directly in metal sheet surface weld bolt, then by bolt with Other connectors carry out being fastenedly connected for engagement thread, and still, bolt can only be in the surrounding edge position of brain head unlike nut, bolt It sets and forms solder joint with metal sheet surface, and the size of brain head is typically small, intensity is difficult to ensure after bolt spot-welded, spiral shell It is easy to fall off after bolt stress, to make connection go wrong.
Invention content
In view of the deficiency of background technology, the technical problem to be solved by the utility model is to provide one kind more preferably to carry out a little Weldering welding, the high fastness of intensity of spot-welded is good, ensures to connect reliable weld bolt.
For this purpose, the utility model is realized using following scheme:
There is weld bolt the cylinder body of rod, the outer circle of the cylinder body of rod to be equipped with screw thread, it is characterised in that:The top of the cylinder body of rod End is equipped with welding boss, and the outside diameter for welding boss is more than the outside diameter of the cylinder body of rod, and the top end surface for welding boss exists Middle position is equipped with column point boss, and the maximum outside diameter and height of the column point boss are no more than 1.5mm.
Weld bolt using the above structure makes the column point boss and metal of welding boss top end surface in spot welding Thin sheet surface contacts, and then carries out spot welding to the surrounding edge position for welding boss, under the action of spot welding high temperature, column point is convex It rises and will produce high temperature melting, metal sheet surface is set in after cooling, be equivalent to and formed and gold in the middle position of welding boss Connection fastening point between metal thin plate surface, and then the intensity of spot-welded is made to be improved, increase firm welding, to ensure The connection of weld bolt and connector is reliable.
Preferably, there is the outer circle of the column point boss up-small and down-big cone to design.Above-mentioned design can make spot welding Shi Zhuzhuan point bosses, which are more also easy to produce high temperature melting and are formed with metal sheet surface, reliably connect fastening point.
Description of the drawings
The utility model has following attached drawing:
Fig. 1 is the structure chart of the weld bolt of utility model,
Fig. 2 is the top-direction view of Fig. 1.
Specific implementation mode
As shown, the weld bolt of the utility model, there is the cylinder body of rod 3, the outer circle of the cylinder body of rod 3 to be equipped with screw thread 4, The top of the cylinder body of rod 3 is equipped with welding boss 2, and the outside diameter of welding boss 2 is more than the outside diameter of the cylinder body of rod 3, welding The top end surface of boss 2 is equipped with column point boss 1 in middle position, and the outer circle of the column point boss 1 is with up-small and down-big Cone designs, and the maximum outside diameter and height of the column point boss 1 are no more than 1.5mm.

Claims (2)
