Abstract
The utility model relates to a screw is riveted to pressure, including the screw body, this screw body includes and mutually perpendicular's horizontal part and vertical portion is equipped with the external screw thread in the vertical portion, forms the thread groove between the external screw thread, is equipped with two oil -outs that parallel in the thread groove, forms the transition passageway of transversely wearing out from the vertical portion between two oil -outs, and the horizontal part and the vertical integrated into one piece of portion of screw body are equipped with a plurality of locking teeth on the terminal surface that the horizontal part orientation is vertical, are equipped with the graduation groove between the adjacent locking tooth. This screw is riveted to pressure is impressed behind the work piece, and locking tooth and firmly interlock of connecting piece have prevented the screw is riveted to pressure rotation effectively, have certain anti torsional strenght, have reached anti -drop's purpose, and this screw is riveted to pressure is suitable for and rivets on some oil pipeline or infusion pipeline, and usual screw is riveted to pressure is the stifled pipeline of dying after the riveting easily, and the transition passageway on this screw can guarantee that the liquid flow of screw both sides is unblocked, and the oil -out setting is in the thread groove in addition, and the oil -out is difficult the jam also.
Description
Technical field
The utility model relates to a kind of screw, especially a kind of self-clinching stud.
Background technique
Self-clinching stud in use need open an aperture on matrix, self-clinching stud is put into hole, adopt parallel uniform at head concora crush of riveting press equipment, because having groove embossing under the head of self-clinching stud, when after press-in, matrix is generation distortion around self-clinching stud, with groove generation scuffing, thus form a firmly outside thread, the defect of present self-clinching stud ubiquity anti-loosing effect difference, easily cause product to come off, thus have impact on the normal use of workpiece, bring potential safety hazard.
Model utility content
The purpose of this utility model is the defect in order to solve in prior art existing for self-clinching stud, provides the self-clinching stud that a kind of anti-loosing effect is good.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of self-clinching stud, comprise screw body, this screw body comprises orthogonal horizontal part and vertical portion, vertical portion is provided with outside thread, it is characterized in that, thread groove is formed between described outside thread, two oil outlets arranged side by side are provided with in thread groove, the transition passage laterally passed from described vertical portion is formed between two oil outlets, horizontal part and the vertical portion of screw body are one-body molded, described horizontal part is provided with some locking teeths towards the end face of vertical portion, is provided with indexing trough between adjacent locking teeth.
Above-mentioned a kind of self-clinching stud, the end of described screw body vertical portion is frustoconical.
Above-mentioned a kind of self-clinching stud, the horizontal part of described screw body and the joint of vertical portion are provided with transition shoulder.
Above-mentioned a kind of self-clinching stud, described transition shoulder is arc.
Above-mentioned a kind of self-clinching stud, the inclined-plane of end, described vertical portion is 45° angle.
Above-mentioned a kind of self-clinching stud, the quantity of described locking teeth is 8.
The beneficial effects of the utility model are: after this self-clinching stud is pressed into workpiece, locking teeth is engaged firmly with link, effectively prevent self-clinching stud to rotate, there is certain torque resistant intensity, reach the object of Drop-proof, this self-clinching stud is suitable for riveting on some oil transport pipelines or liquid-transport pipe-line, usual self-clinching stud easily blocks pipeline after staking, and the transition passage on this screw can ensure that the flow of fluid of screw both sides is unimpeded, and oil outlet is arranged in thread groove, oil outlet also not easily blocks.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is worm's eye view of the present utility model.
Embodiment
Further understand for making to have structure characteristic of the present utility model and effect of reaching and be familiar with, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
As Fig. 1, shown in Fig. 2, a kind of self-clinching stud, comprise screw body, this screw body comprises orthogonal horizontal part 1 and vertical portion 2, vertical portion 2 is provided with outside thread, as improvement of the present utility model, thread groove 6 is formed between outside thread, two oil outlets 7 arranged side by side are provided with in thread groove 6, the transition passage 8 laterally passed from vertical portion 2 is formed between two oil outlets 7, this self-clinching stud is suitable for riveting on some oil transport pipelines or liquid-transport pipe-line, usual self-clinching stud easily blocks pipeline after staking, and the transition passage 8 on this screw can ensure that the flow of fluid of screw both sides is unimpeded, and oil outlet 7 is arranged in thread groove 6, oil outlet 7 also not easily blocks, horizontal part 1 and the vertical portion 2 of screw body are one-body molded, horizontal part 1 is provided with some locking teeths 3 towards the end face of vertical portion 2, the quantity of locking teeth 3 is preferably 8, indexing trough is provided with between adjacent locking teeth 3.
Further, the end 4 of screw body vertical portion 2 is frustoconical, the inclined-plane of end 4 is 45° angle, being convenient to screw body is pressed in workpiece, the vertical portion 2 of screw body and the joint of horizontal part 1 are provided with transition shoulder 5, and transition shoulder 5 is arc, are convenient to after screw body is pressed into workpiece, the transition shoulder curved portions of 5 is engaged with the joint of workpiece, serves the object preventing from coming off.
After this self-clinching stud is pressed into workpiece, locking teeth 3 is engaged firmly with link, effectively prevent self-clinching stud and rotates, have certain torque resistant intensity, reach the object of Drop-proof.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
