Description
Technical field
This utility model relates to technical field of fastening, is specifically related to a kind of novel self-clinching stud.
Background technology
Self-clinching stud in use need to open an aperture on matrix, and self-clinching stud is put into hole, uses riveting
Parallel uniform at head concora crush, because of the head downstream groove embossing of self-clinching stud, when, after press-in, matrix is at the spiral shell that presses of equipment
The surrounding of nail is deformed, and groove generation scuffing, thus forms a firm external screw thread.But the existing spiral shell that presses
Generally there is the defect of anti-loosing effect difference in nail, is easily caused product and comes off, thus have impact on the normal use of workpiece, brings peace
Full hidden danger.
Utility model content
In order to overcome the deficiency of background technology, this utility model provides a kind of novel self-clinching stud, mainly solves existing
Self-clinching stud anti-loosing effect difference cause the problem that product comes off, this novel self-clinching stud simple and reasonable, pass through screw
On the mode of colored tooth, relief groove and protective layer is set, effectively prevent and occur between connector to loosen, improve the whole of self-clinching stud
Body performance, has with low cost simultaneously, and practical simple, safety is good, and service life is long, it is easy to promote.
This utility model be the technical scheme is that a kind of novel self-clinching stud, and it includes screw body, described screw
Body lateral cross section is T-shaped, and screw body includes orthogonal screw head and shank of screw portion, screw head and shank of screw
Portion is that integral type structure is arranged, and is provided with colored teeth portion, relief groove and the vertebral body portion being fixedly connected sequentially, flower tooth below screw head
It is provided with in portion and is uniformly distributed colored tooth, be provided with a draw-in groove between the most adjacent two colored teeth, shank of screw portion is provided with outer spiral shell
Stricture of vagina, external screw thread is connected with each other with vertebral body portion, and external screw thread lower end is provided with circular thread；Described shank of screw portion surface configuration is protected
Layer, the material of protective layer is preferentially set to Dyclo paint；The width of described draw-in groove is more than the width of described colored tooth, two adjacent flowers
Angle between tooth is set to 30 degree；The two ends up and down of described relief groove are provided with the fillet I that radius is 0.1mm；Described screw
The fillet II that radius is 0.75mm it is provided with on the lower surface in bar portion.
The beneficial effects of the utility model are: owing to taking technique scheme, the simple in construction of this novel self-clinching stud
Rationally, by the way of colored tooth, relief groove and protective layer are set on screw, effectively prevent and occur between connector to loosen, improving
The overall performance of self-clinching stud, has with low cost simultaneously, and practical simple, safety is good, service life is long, it is easy to promote.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model embodiment is described further:
As shown in Fig. 1 to Fig. 4, a kind of novel self-clinching stud, it includes screw body, described screw body lateral cross section in
T-shaped, it is integral type that screw body includes orthogonal screw head 1 and shank of screw portion 2, screw head 1 and shank of screw portion 2
Structure is arranged, and is provided with colored teeth portion 3, relief groove 4 and the vertebral body portion 5 being fixedly connected sequentially below screw head 1, connected piece
A part of material is extruded in relief groove 4, thus vertebral body portion 5 forms coupling mechanism force to connected piece, simultaneously relief groove 4 with connected
Can there be gap between fitting thus alleviate intrinsic pressure, flower teeth portion 3 be provided with and is uniformly distributed colored tooth 6, flower tooth 6 and connected piece phase
Occlusion prevents from loosening mutually, is provided with a draw-in groove 7, shank of screw portion 2 is provided with external screw thread 8, outward between the most adjacent two colored teeth 6
Screw thread 8 is connected with each other with vertebral body portion 5, and external screw thread 8 lower end is provided with circular thread 9.
Described shank of screw portion 2 surface configuration matcoveredn, the material of protective layer is preferentially set to Dyclo paint.
The width of described draw-in groove 7 is more than the width of described colored tooth 6, and the angle between two adjacent colored teeth 6 is set to 30 degree.
The two ends up and down of described relief groove 4 are provided with the fillet I 10 that radius is 0.1mm.
The fillet II 11 that radius is 0.75mm it is provided with on the lower surface in described shank of screw portion 2.
This novel self-clinching stud simple and reasonable, by arranging colored tooth 6, relief groove 4 and the side of protective layer on screw
Formula, effectively prevents and occurs between connector to loosen, improve the overall performance of self-clinching stud, have with low cost simultaneously, practical
Simply, safety is good, and service life is long, it is easy to promote.
Every technical staff's notice: although this utility model describes according to above-mentioned detailed description of the invention, but this
The invention thought of utility model is not limited to that utility model, the repacking of any utilization inventive concept, all will include this in specially
In profit scope of patent protection.
