Description
Technical field
This utility model is related to a kind of bolt, more particularly to a kind of bolt with internal-fastening type torque platen.
Background technology
Current electric power bolt, when tightening, although crimp force enough, but bolt because extruding is torn, twist can be directly
The core of electric wire is hurt, is made core sustain damage even and is ruptured, reduce the conductive area of core, affect the electrical efficiency of electric wire
And service life, when there is sporadic excessively stream, as the core of coupling part is damaged, conductive area is not enough, it might therefore
Can there is potential safety hazard；Also there are the attachment means that bolt and briquetting coordinate, although can realize not hindering line, but need to use simultaneously
Two parts of bolt and briquetting, convenience are not enough.
Content of the invention
Technical problem to be solved in the utility model is to provide for a kind of internal-fastening type torque platen bolt, and it effectively can solve
Can make core impaired when certainly tightening electric wire with bolt and the inconvenience of part excessive use problem, with easy to use, dynamics moderate,
Durable the characteristics of.
For achieving the above object, the technical solution adopted in the utility model is：A kind of internal-fastening type torque platen bolt, including
Bolt body, is provided with outer-hexagonal bolt head above main body, connected by fracture one between main body and outer-hexagonal bolt head, and outward six
The endoporus one being communicated with inside corner bolt head and fracture one, it is characterised in that：Be provided with platen below the main body, main body with
Connected by limiting section between platen, between limiting section and platen, be provided with fracture two, being less than by dynamics for fracture two is ruptured
Portion one by dynamics.
Further, endoporus two is provided with the platen, and the height of endoporus two is less than the height of platen.
Further, external diameter of the external diameter of the endoporus two more than limiting section.
Further, height and fracture two thickness sum of the height of the endoporus two more than limiting section.
Further, the hexagon socket head cap screw hole that main body can be twisted by instrument, hexagon socket head cap screw are provided with the main body
Hole is from top to bottom through whole main body and limiting section.
Further, the limiting section is in gradual taper from top to bottom.
Further, two lower end of the endoporus is provided with the bell being engaged with the bottom of limiting section.
This utility model employs above-mentioned technical scheme, overcomes the deficiency of background technology, there is provided a kind of internal-fastening type power
Square platen bolt, its energy effectively solving bolt can make, when tightening electric wire, the problem that core is impaired and part excessive use is inconvenient,
Have easy to use, dynamics moderate, durable the characteristics of.
Description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is cross-sectional view of the present utility model.
In figure：Main body 1, outer-hexagonal bolt head 2, fracture 1, endoporus 1, platen 5, limiting section 6, fracture 27, interior
Hole 28, bell 8a, hexagon socket head cap screw hole 9.
Specific embodiment
Below in conjunction with the accompanying drawings, by being further described to specific embodiment of the present utility model, make this practicality new
The technical scheme and its advantage of type is clearer, clear and definite.
Referring to accompanying drawing 1 to 2, this utility model includes bolt body 1, is provided with outer-hexagonal bolt head 2, main body 1 above main body 1
It is connected by fracture 1 between outer-hexagonal bolt head 2, be communicated with inside outer-hexagonal bolt head 2 and fracture 1 is interior
Hole 1, it is characterised in that：Platen 5 is provided with below the main body 1, is connected by limiting section 6 between main body 1 and platen 5, spacing
Be provided with fracture 27 between portion 6 and platen 5, fracture 27 by dynamics less than fracture 1 by dynamics.
Further, endoporus 28 is provided with the platen 5, and the height of endoporus 28 is less than the height of platen 5.
Further, external diameter of the external diameter of the endoporus 28 more than limiting section 6.
Further, height and fracture two 7 thickness sum of the height of the endoporus 28 more than limiting section 6.
Further, the hexagon socket head cap screw hole 9 that main body 1 can be twisted by instrument, interior hexagonal spiral shell are provided with the main body 1
Keyhole 9 is from top to bottom through whole main body 1 and limiting section 6.
Further, the limiting section 6 is in gradual taper from top to bottom.
Further, 28 lower end of the endoporus is provided with the bell 8a being engaged with the bottom of limiting section 6.
When in use, main body 1 is twisted by outer-hexagonal bolt head 2 with instrument, main body 1 drives platen 5 to be pressed down against,
When the dynamics that extruding dynamics is can bear more than fracture 27, the fracture of fracture 27 makes main body 1 separate with platen 5, is leading
Continue to be rotated down on body and platen 5 is pushed up in the case of combining by extruded core resilience, limiting section 6 is inserted into pressure
Endoporus 28 on disk 5, now, as main body 1 and platen 5 fracture separation, platen 5 are enclosed within limiting section 6, platen 5 is relative
It is movable for main body 1, even if main body 1 continues to twist, platen 5 will not also follow main body to continue rotation；Continue to twist master
When body 1 is more than the dynamics that fracture 1 can bear to the dynamics that twists, the fracture of fracture 1 makes main body 1 and outer-hexagonal bolt
2 separate, and the dynamics that now bolt applies to electric wire is most suitable, both can guarantee that the fixed dynamics of electric wire, while guarantee is electric
The core of line will not be subject to excessive compression and be damaged.
After fracture 27 ruptures, even if main body 1 continues rotary squeezing, platen 5 also will not be rotated with main body 1 again, so as to
Avoid core is caused to damage；After fracture 27 ruptures, can also some remain in limiting section 6, another part remains in
28 upper end of hole, the fracture 27 for remaining in limiting section 6 can be stuck in 28 lower end of endoporus after platen 5 is set to limiting section 6
On bell 8a, while the fracture 27 remained on endoporus 28 can also block the limiting section 6 of taper, in this case, i.e.,
Make reversion unclamp main body 1, platen 5 also can be enclosed within always limiting section 6 can avoid without falling down, so platen 5 with
Meaning drops out generation harmful effect, and two can be in the case of screw not be replaced, additionally it is possible to reused, when reusing
Original effect for not hindering line can also be kept.
By the description of above-mentioned structure and principle, person of ordinary skill in the field should be appreciated that this utility model
Above-mentioned specific embodiment is not limited to, the improvement and replacement using techniques well known on the basis of this utility model is equal
Fall in protection domain of the present utility model, should be limited by each claim.
