And release influence bolt normal use, existing bolt inconvenience to bolt carry out oiling maintenance, when need to bolt carry out
Oiling also needs to back out on bolt when maintenance and carries out oiling to bolt again and then tighten bolt again, cumbersome, because
This is necessary to propose a kind of new bolt.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of Multifunctional bolt, can be effective
Prevent bolt from arbitrarily being dismantled by other people, effectively prevent bolt looseness, it is convenient that oiling maintenance is carried out to bolt, improve bolt use
Safety and reliability, it is simple in construction, it is easy to use, it is easy to utilize.
To achieve the above object, the utility model proposes a kind of Multifunctional bolt, including nut, screw rod, mounting groove, four
Terrace with edge, through hole, discharge orifice and anti-skidding convex tendon, the bottom of the nut are fixed with screw rod, and the top of the nut is provided with cylinder
Mounting groove, the bottom land of the mounting groove is fixed with two truncated rectangular pyramids being engaged, the bottom land of the mounting groove and screw rod
Through through hole is provided between lower end, the sidepiece of the screw rod offers multiple discharge orifices communicated with through hole, the spiral shell from top to bottom
The bottom of cap is fixed with a plurality of anti-skidding convex tendon.
Preferably, the nut is in cylinder design, radial distribution of the anti-skidding convex tendon along nut.
Preferably, one of side of the truncated rectangular pyramids is designed for scarf, described two truncated rectangular pyramids are with mounting groove
Axis be symmetrical arranged for symmetry axis and one of truncated rectangular pyramids are located at the opposite slightly to the right or left of another truncated rectangular pyramids, described two truncated rectangular pyramids
Inclined-plane is relative and two inclined-planes between minimum distance be 1mm, it is vertical between the relative vertical plane of described two truncated rectangular pyramids
Straight distance is 1mm, and the height of the truncated rectangular pyramids is identical with the height of mounting groove.
Preferably, the anti-skidding convex tendon is triangular prism shaped design.
The beneficial effects of the utility model：The utility model is fixed with screw rod by the bottom in nut, in nut
Top is provided with the mounting groove of cylinder, two truncated rectangular pyramids being engaged is fixed with the bottom land of mounting groove, in the groove of mounting groove
Through through hole is provided between bottom and the lower end of screw rod, multiple streams communicated with through hole are offered from top to bottom in the sidepiece of screw rod
Hole, a plurality of anti-skidding convex tendon is fixed with the bottom of nut, can be by the cutter head card of screwdriver when the bolt is being used
Between the relative vertical plane of two truncated rectangular pyramids, then go to screwdriver and bolt is tightened, due to one of truncated rectangular pyramids
Side is designed for scarf and the inclined-plane of two truncated rectangular pyramids is relative, when screwdriver is unscrewed to bolt, screwdriver
It can be skidded between cutter head and the inclined-plane of truncated rectangular pyramids and make it that the rotatory force of screwdriver cannot be light from being transmitted to bolt, such bolt
Easy unscrews, because truncated rectangular pyramids are located in mounting groove and truncated rectangular pyramids are identical with the height of mounting groove, so it is prevented that
Two truncated rectangular pyramids are clamped with spanner to dismantle bolt, due to there is provided through hole and discharge orifice, when needing to carry out oiling to bolt
When maintenance, directly lubricating oil can be injected from the upper end of through hole, it may not be necessary to which demounting bolt can be noted to bolt
Oil maintenance, it is in anti-skidding convex tendon meeting insert body and then anti-when bolt is fastened due to being provided with anti-skidding convex tendon in the bottom of nut
Only the bolt produces loosening due to vibrations, compared with prior art, can effectively prevent bolt from arbitrarily being dismantled by other people, effectively
Bolt looseness is prevented, it is convenient that oiling maintenance is carried out to bolt, the safety and reliability that bolt uses is improved, it is simple in construction,
It is easy to use, it is easy to utilize.
Feature and advantage of the present utility model will be described in detail by embodiment combination accompanying drawing.
【Brief description of the drawings】
Fig. 1 is a kind of structural representation of Multifunctional bolt of the utility model.
Fig. 2 is a kind of structure top view of Multifunctional bolt of the utility model.
In figure：1- nuts, 2- screw rods, 3- mounting grooves, 5- truncated rectangular pyramids, 6- through holes, 7- discharge orifices, the anti-skidding convex tendons of 8-.
【Embodiment】
Refering to Fig. 1 and 2, a kind of Multifunctional bolt of the utility model, including nut 1, screw rod 2, mounting groove 3, truncated rectangular pyramids 5,
Through hole 6, discharge orifice 7 and anti-skidding convex tendon 8, the bottom of the nut 1 are fixed with screw rod 2, and the top of the nut 1 is provided with cylinder
Mounting groove 3, the bottom land of the mounting groove 3 is fixed with two truncated rectangular pyramids being engaged 5, the bottom land and spiral shell of the mounting groove 3
