Description
Technical field
The utility model relates to technical field of fastening, particularly relates to a kind of bolt.
Background technique
At present, bolt of the prior art is generally made up of bolt head and screw rod, the bottom of screw rod is provided with cone, although this structure has guiding accurately because screw rod bottom is provided with cone two when mounted, the not easily feature of stripped thread, but or some deficiency: owing to there is the impurity such as metal fillings, greasy filth in internal thread, cause in installation process, occurring that moment of torsion is excessive, and actual bolt pretightening does not reach designing requirement, moment of torsion can be caused to decay after often using a period of time, there is the inefficacies such as abnormal sound in component; And during due to screw-thread fit, sealing is better, and the normal time uses, and there will be ponding between screw thread, easily produces corrosion.
Model utility content
In order to overcome deficiency of the prior art, the utility model provides a kind of bolt.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
According to an aspect of the present utility model, provide a kind of bolt, comprise: bolt head and screw rod, described bolt head and described screw rod contact position are provided with hexagon head or flange plate, the polished rod that described screw rod comprises close hexagon head or flange plate end, the cone being positioned at the worm structure in the middle part of screw rod and being positioned at bottom screw rod, the screw thread of described worm structure is provided with multiple slot scraping structure caved inward.
Alternatively, multiple slot scraping structure is 4, and the outer surface of described worm structure is evenly arranged.
Alternatively, the center line of described multiple slot scraping structure is crossing with the screw thread of described worm structure in predetermined angle.
Alternatively, described predetermined angle is 30 degree.
Alternatively, described slot scraping structure is wedge type groove.
Alternatively, described slot scraping structure is coated with zinc-aluminium coating layer.
The beneficial effects of the utility model: the worm structure in bolt of the present utility model carries slot scraping structure, decrease to scrape and unload groove operation, and can the chip in internal thread, greasy dirt etc. be concentrated in slot scraping structure when the link with the material such as cast iron, cast aluminium, steel is installed, be conducive to installing, being conducive to reducing the moment of torsion decay, abnormal sound etc. that cause because of false moment of torsion.
Further, the bolt in the utility model in use can water guide, electrolyte can not be existed and screw in position, avoid premature corrosion occurs, reduce further cost.

Embodiment
For making the technical problems to be solved in the utility model, technological scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Fig. 1 ~ Fig. 2, embodiment of the present utility model provides a kind of bolt, comprise: bolt head 1 and screw rod 2, described bolt head 1 is provided with hexagon head or flange plate (not shown) with described screw rod contact position, the polished rod 201 that described screw rod 2 comprises close hexagon head or flange plate end, the cone 203 being positioned at the worm structure 202 in the middle part of screw rod 2 and being positioned at bottom screw rod 2, the screw thread of described worm structure 202 is provided with multiple slot scraping structure 204 caved inward.
In embodiment of the present utility model, worm structure in bolt carries slot scraping structure, decrease to scrape and unload groove operation, and can the chip in internal thread, greasy dirt etc. be concentrated in slot scraping structure when the link with the material such as cast iron, cast aluminium, steel is installed, be conducive to installing, being conducive to reducing the moment of torsion decay, abnormal sound etc. that cause because of false moment of torsion.
Further, continue see Fig. 2, described multiple slot scraping structure 204 is 4, and the outer surface of described worm structure 202 is evenly arranged.It is appreciated of course that, in embodiment of the present utility model, do not limit the concrete quantity of this slot scraping structure 204, in actual applications, the concrete quantity that this slot scraping structure 204 is set can be carried out as required.
Further, the center line of described multiple slot scraping structure 204 is crossing with the screw thread of described worm structure 202 in predetermined angle, and wherein said predetermined angle is 30 degree.It is appreciated of course that, in embodiment of the present utility model, do not limit the concrete numerical value of this predetermined angle, in actual applications, can need to carry out the concrete numerical value arranging this predetermined angle according to actual conditions.
Further, described slot scraping structure 204 is wedge type groove, it is appreciated of course that this slot scraping structure 204 also can be the structures such as dovetail groove.
Further, described slot scraping structure 204 is coated with zinc-aluminium coating layer.Bolt of the present utility model in use can water guide, electrolyte can not be existed and screw in position, avoid premature corrosion occurs, reduce further cost.
Fig. 3 is the schematic diagram of the bolt of the utility model embodiment when assembling, when bolt is screwed in link 3, owing to carrying slot scraping structure 204, can the chip in internal thread, greasy dirt etc. be concentrated in slot scraping structure 204 when the link with the material such as cast iron, cast aluminium, steel is installed, be conducive to the convenience of installation process, be conducive to reducing the moment of torsion decay, abnormal sound etc. that cause because of false moment of torsion.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
