Abstract
The utility model provides a welding pressure-proof and anti-thread-off bolt, which includes a bolt bar and a bolt head, wherein a plurality of outer convex soldering points are arranged on the bolt head; the bolt is provided with three outer convex soldering points; and the three outer convex soldering points are uniformly distributed on the bolt head and are equidistant to the circle center of the bolt head. Through the adoption of the welding pressure-proof and anti-thread-off bolt provided by the utility model, the outer convex soldering points are arranged on the bolt head, after the bolt is assembled with a part with a hole, the bolt is tightly pressed between two electrodes, the outer convex soldering points are molten through resistance heat, so that the bolt is welded with the part with the hole, and then the bolt is tightly screwed, as a result, the bolt is effectively prevented from loosing or threading off, and the entire pressure-proof performance of the bolt is improved through the welding structure.
Description
Technical field
The utility model belongs to fastener areas, is specifically related to the withstand voltage anticreep bolt of a kind of welding.
Background technique
Bolt is by bolt head and bolt shank (having externally threaded cylindrical body) one type of fastening piece dimerous.Bolt needs to cooperate with nut, is used to be fastenedly connected two parts that have through hole, and this Connecting format claims that bolt connects.When existing bolt was connected with the part that has through hole, it only was to insert in the through hole, cooperates with nut and screws; This mode occurs nuts and bolt easily and comes off under work long hours back or the environment in bigger vibration, has certain potential safety hazard.
The model utility content
The utility model provides a kind of welding withstand voltage anticreep bolt to the deficiency of above-mentioned existing technology, and this welds withstand voltage anticreep bolt and can weld together with link, effectively prevents bolt falling.
The utility model is realized through following technological scheme:
The withstand voltage anticreep bolt of a kind of welding comprises bolt shank and bolt head, and said bolt head is provided with a plurality of evagination solder joints.
The further setting of the utility model is that said evagination solder joint is three.
The further setting of the utility model is that said three evagination solder joints are evenly distributed on the bolt head, and equates with the distance in the bolt head center of circle.
The further setting of the utility model is that the diameter of said bolt head is 19 millimeters.
The further setting of the utility model is that the diameter of said evagination solder joint is 3.9 millimeters.
The further setting of the utility model is that the distance between the center of circle of said evagination solder joint and the center of circle of bolt head is 8.1 millimeters.
The described welding of the utility model is withstand voltage anticreep bolt is provided with a plurality of evagination solder joints on bolt head, after bolt and part with holes assembling are accomplished; Bolt is pressed between two electrodes; Utilize resistance heat to melt the evagination solder joint, bolt and part with holes are welded together the nut of screwing again afterwards; So can effectively prevent bolt looseness and come off that the structure of welding type can make the whole resistance to pressure of bolt stronger simultaneously.
Description of drawings
Fig. 1 is the plan view of the withstand voltage anticreep bolt of the said welding of the utility model;
Fig. 2 is the worm's eye view of the withstand voltage anticreep bolt of the said welding of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Like Fig. 1, shown in 2, the utility model provides a kind of welding withstand voltage anticreep bolt, comprises bolt shank 1 and bolt head 2, and the outer installment of bolt shank 1 has outside thread, and bolt head 2 is provided with a plurality of evagination solder joints 3.Preferably, the number of evagination solder joint 3 is three, can certainly select more a plurality of according to actual needs.In order to make the anticreep better effects if of bolt, said three evagination solder joints 3 are evenly distributed on the bolt head 2, and equate with the distance in bolt head 2 centers of circle.The diameter of the bolt head in the present embodiment is 19 millimeters; The diameter of evagination solder joint is 3.9 millimeters; It is that promptly the distance between the center of circle of evagination solder joint and the bolt head center of circle is 8.1 millimeters on 16.2 millimeters the circle that the evagination solder joint is evenly distributed on diameter, and the angle between three evagination solder joints 3 is 120 degree.
The above is the preferred embodiment of the utility model, and all equivalent variations of being done according to the utility model claim all should belong to the protection domain of the utility model.
