Abstract
The utility model relates to bolt technical field, specifically a kind of permeable bolt of supporting surface fluting.A kind of permeable bolt of supporting surface fluting, comprise bolt head, screw rod, it is characterized in that: the lower end connecting screw rod of bolt head, on the lower end surface of bolt head, annular is laid with some permeable grooves, the screw rod connecting permeable groove one end is provided with another permeable groove, one end of another described permeable groove is connected with permeable groove one end, and the other end of another permeable groove flushes with bottom screw rod; Described permeable groove and another permeable groove are long strip groove.Compared with the existing technology, bolt screw rod, head are outputed the permeable groove be interconnected that size is suitable, permeable nut is coordinated to use, make the liquid such as the water in connecting body, by the permeable groove of permeable nut and permeable bolt, export to outside, prevent the inner existence due to liquid such as water of connecting body, produce the corrosion phenomenons such as corrosion.
Description
Technical field
The utility model relates to bolt technical field, specifically a kind of permeable bolt of supporting surface fluting.
Background technique
Its head of traditional bolt and screw rod are all complete plane and arc surface, like this when connecting, can fit completely with surface of contact, reach and increased surface of contact friction, improved and connect fastening effect, but, the equipment of and underwater operation moist at some, do not discharge in time owing to there is moisture between surface of contact, then can cause the phenomenons such as the corrosion of surface of contact, affect the working life of equipment.
Summary of the invention
The utility model is for overcoming the deficiencies in the prior art, bolt screw rod, head are outputed the permeable groove be interconnected that size is suitable, permeable nut is coordinated to use, make the liquid such as the water in connecting body, by the permeable groove of permeable nut and permeable bolt, export to outside, prevent the inner existence due to liquid such as water of connecting body, produce the corrosion phenomenons such as corrosion.
For achieving the above object, design the permeable bolt of a kind of supporting surface fluting, comprise bolt head, screw rod, it is characterized in that: the lower end connecting screw rod of bolt head, on the lower end surface of bolt head, annular is laid with some permeable grooves, the screw rod connecting permeable groove one end is provided with another permeable groove, and one end of another described permeable groove is connected with permeable groove one end, and the other end of another permeable groove flushes with bottom screw rod; Described permeable groove and another permeable groove are long strip groove.
The other end of described permeable groove and bolt head outer rim end face.
Described permeable groove and another permeable groove are at least provided with 3.
The outer rim of described screw rod is provided with screw thread.
The lower end surface of described bolt head is provided with boss.
The utility model compared with the existing technology, bolt screw rod, head are outputed the permeable groove be interconnected that size is suitable, permeable nut is coordinated to use, make the liquid such as the water in connecting body, by the permeable groove of permeable nut and permeable bolt, export to outside, prevent the inner existence due to liquid such as water of connecting body, produce the corrosion phenomenons such as corrosion.
Bolt can be flange bolt, and also can be hex head bolt, its shape not be limit, and fluting quantity and size use by reality to be determined, can also slot in head rod junction, liquid of being more convenient for flows out if needed.
Accompanying drawing explanation
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure plan view.
Fig. 3 is the utility model structure worm's eye view.
See Fig. 1 to Fig. 3,1 is bolt head, and 2 is screw rod, and 3 is screw thread, and 4 is permeable groove, and 5 is boss, and 6 is another permeable groove.
Embodiment
With reference to the accompanying drawings the utility model is described further below.
As shown in Figure 1 to Figure 3, the lower end connecting screw rod 2 of bolt head 1, on the lower end surface of bolt head 1, annular is laid with some permeable grooves 4, the screw rod 2 connecting permeable groove 4 one end is provided with another permeable groove 6, one end of another described permeable groove 6 is connected with permeable groove 4 one end, and the other end of another permeable groove 6 flushes with bottom screw rod 2; Described permeable groove 4 and another permeable groove 6 are long strip groove.
The other end of permeable groove 4 and bolt head 1 outer rim end face.
Permeable groove 4 and another permeable groove 6 are at least provided with 3.
The outer rim of screw rod 2 is provided with screw thread 3.
The lower end surface of bolt head 1 is provided with boss 5.
The screw rod 2, bolt head 1 of bolt are outputed the permeable groove be interconnected that size is suitable, permeable nut is coordinated to use, make the liquid such as the water in connecting body, by the permeable groove of permeable nut and permeable bolt, export to outside, prevent the inner existence due to liquid such as water of connecting body, produce the corrosion phenomenons such as corrosion.
Bolt can be flange bolt, and also can be hex head bolt, its shape not be limit, and fluting quantity and size use by reality to be determined, can also slot in head rod junction, liquid of being more convenient for flows out if needed.
