Description
Technical field
This utility model relates to bolt technical field, is specifically related to a kind of New self-tapping Anti-off bolt.
Background technology
Existing tap bolt generally includes a screw rod, and one end of this screw rod is provided with a head, and the other end is provided with a drill bit. When using this tap bolt, can first be attacked on self tapping object by the cutting edge of drill bit and cut a circular hole, then pass through screw rod rotation and lock on self tapping object, reach the purpose of convenient locking. Existing tap bolt structure there is also deficiency: the chip area of existing tap bolt is generally a V-shaped groove, and the space of its accommodating crumble is relatively limited; Meanwhile, the precession end of this V-arrangement chip area and unscrewing end are obtuse angle, are easily caused the crumble that tap bolt produces in locking process and are difficult to successfully be entered chip area by precession end, and this precession end also is difficult to effectively be discharged from chip area by the crumble of remnants. Thus, being smoothed out of tap bolt locking operation is easily affected.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is in that to provide that a kind of reasonable in design, simple in construction, chip removal be smooth and easy, the New self-tapping Anti-off bolt of reliable operation, good anti-drop effect.
For achieving the above object, this utility model provides following technical scheme: a kind of New self-tapping Anti-off bolt, including bolt body, described bolt body is disposed with bolt head from top to bottom, polished rod and screw rod, the diameter of described polished rod is less than major diameter of thread, described screw rod lower end has been wholely set drill bit, at least provided with two chip areas on described screw flight, every chip area is arc groove, and the precession end of every chip area is arc chord angle, upper end, described bolt head side has been wholely set two block welding lugs, the thickness of every block welding lug is 1mm, and every welding lug is at least vertically arranged with a welding hole.
By adopting technique scheme, it is provided with the polished rod less than this threaded rod diameter in threaded rod upper end and can be effectively improved the volume space of crumble, and debris discharging chute structure arranges rationally, precession end contributes to crumble and enters smoothly in chip area after being set to arc chord angle, and easily remnants crumble is discharged from chip area, it is ensured that being smoothed out of tap bolt locking operation; Welding lug arranges rationally, easy to connect, welds with existing self tapping object by welding lug, fixes reliably, and reasonable in design, simple in construction, chip removal are smooth and easy, reliable operation, good anti-drop effect.
This utility model is further arranged to: the diameter 1.5-2mm less of the diameter of described screw rod of described polished rod.Structure arranges more reasonable, and chip removal is convenient.
This utility model is further arranged to: be socketed with a rubber sleeve on described polished rod, and the thickness of described rubber sleeve is 0.5mm, and has been wholely set multiple positioning convex on described rubber sleeve. By this setting, rubber sleeve arranges rationally, good positioning effect.
This utility model is further arranged to: upper end, described bolt head side has been wholely set two block welding lugs, and two block welding lugs are mutually symmetrical with. By this setting, welding lug quantity arranges rationally, connects reliable.
This utility model is further arranged to: described bolt head, polished rod and screw rod are structure as a whole. By this setting, structure arranges more reasonable, works relatively reliable.
The utility model has the advantages that: compared with prior art, it is more reasonable that this utility model structure is arranged, it is provided with the polished rod less than this threaded rod diameter in threaded rod upper end and can be effectively improved the volume space of crumble, and debris discharging chute structure arranges rationally, precession end contributes to crumble and enters smoothly in chip area after being set to arc chord angle, and easily remnants crumble is discharged from chip area, it is ensured that being smoothed out of tap bolt locking operation; Welding lug arranges rationally, easy to connect, welds with existing self tapping object by welding lug, fixes reliably, and reasonable in design, simple in construction, chip removal are smooth and easy, reliable operation, good anti-drop effect.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Referring to Fig. 1, the disclosed a kind of New self-tapping Anti-off bolt of this utility model, including bolt body, described bolt body is disposed with bolt head 1 from top to bottom, polished rod 2 and screw rod 3, the diameter of described polished rod 2 is less than the major diameter of thread of screw rod 3, described screw rod 3 lower end has been wholely set drill bit 31, at least provided with two chip areas 32 on the screw thread of described screw rod 3, every chip area 32 is arc groove, and the precession end of every chip area 32 is arc chord angle, upper end, described bolt head 1 side has been wholely set two block welding lugs 11, the thickness of every block welding lug 11 is 1mm, and every welding lug 11 is at least vertically arranged with a welding hole 111.
For making this utility model structure more reasonable, as preferably, the diameter of polished rod 2 1.5-2mm (millimeter) less of the diameter of described screw rod 3 described in the present embodiment.
Being socketed with a rubber sleeve 4 on described polished rod 2, the thickness of described rubber sleeve 4 is 0.5mm, and has been wholely set multiple positioning convex 41 on described rubber sleeve 4.
