Fig. 2 is the structural schematic diagram of screw rod.
Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
Please refer to Fig. 1, Fig. 2, the utility model provides a kind of engine Special high-strength bolt, including screw rod 1, is set to spiral shell
The screw head 2 at 1 top of bar and the external screw thread 3 on 1 outer wall of screw rod, the screw rod 1 is interior to be equipped with a cushion hole 4, and cushion hole 4 is in
Positive triangle prism-shaped；Matched reinforcement prism is installed in the cushion hole 4；The reinforcement prism includes several in vertical
To equally distributed detent frame 5, detent frame 5 is in equilateral triangle；It is fixed between the detent frame 5 by 6 phase of support rod；The card
Position 5 center position of frame is equipped with one and is spirally connected set 7；The set 7 that is spirally connected is externally connected with three connecting rods being circularly and evenly distributed
8,8 one end of connecting rod is connected to 5 corner location of detent frame；4 bottom of cushion hole is equipped with the first bolt apertures 9, the first bolt apertures 9
Set 7 is concentric with being spirally connected；The screw head 2 is equipped with a perforation 10 to connect with cushion hole 4；The bottom end of one auxiliary screw 11 is from upper
Perforation 10 is sequentially passed through under, be spirally connected set 7, and be bolted in the first bolt apertures 9；2 two sides of screw head are equipped with mutually symmetrical
Mounting hole 12, mounting hole 12 connect with perforation 10；12 bottom surface of mounting hole is equipped with a sliding slot 13；Peace in the mounting hole 12
Equipped with a limited block 14；The limited block 14 side opposite with the auxiliary spiral shell body of screw 11 is equipped with a U-shaped limited location fork 15；
An annular slot 16 to match with limited location fork 15 is equipped with the spiral shell of the auxiliary screw 11；14 bottom width of limited block
Greater than 13 width of sliding slot, 14 bottom surface of limited block is equipped with the sliding block 17 to match with sliding slot 13；11 both sides of the head of auxiliary screw
Equipped with the limiting device to match with sliding block 17.
The limiting device includes the second bolt apertures 18 set on auxiliary 11 both sides of the head of screw, and the second bolt apertures 18 are located at
Right above sliding slot 13；Second bolt apertures 18 are bolted with butterfly screws 19, and 19 bottom end of butterfly screws is pressed on 13 bottom of sliding slot, butterfly
19 spiral shell body of shape screw is against on sliding block 17.
The application method of the utility model is as follows:
Before the bolt using the utility model, first auxiliary screw 11 can be screwed out out of screw rod 1, in screw rod 1 at this time
Portion, which only has, reinforces prism 5, and reinforces prism 5 after losing auxiliary screw 11, can move down in the track freedom of cushion hole 4
Dynamic, the presence of cushion hole 4 makes screw rod 1 become non-solid structure, so that screw rod 1 itself be made to obtain the effect of buffering, and reinforces rib
Column 5 is mainly made of detent frame 5, support rod 6, connecting rod 8, thus reinforce prism 5 be equivalent to it is assembled by plurality of rods, it is each
There are space between root, which can then make reinforcement prism 5 itself equally have the effect of buffering, reinforce prism phase at the same time
When being equivalent to the keel for having set up a screw rod 1 in cushion hole 4 in being filled in cushion hole 4, propose 1 intensity of screw rod
It rises, and detent frame 5 is in equilateral triangle, equilateral triangle structure is the most stable, can be maximum in the reinforcement prism of positive triangle prism-shaped
Guarantee the intensity itself being able to ascend in degree.
When bolt is when the screw hole of the perforation and another component that pass through a component is spirally connected, if there is external force
When bending the screw rod 1 of bolt, cushion hole 4 then can simultaneously buffer the external force with prism is reinforced, to avoid screw rod 1
Bending, after bolt completion is spirally connected, staff can screw 11 sequentially passes through perforation 10 from top to bottom, be spirally connected set 7 by auxiliary, and
Be bolted in the first bolt apertures 9, at this time reinforce prism position fixed, and assist screw 11 presence can by screw rod 1,
Screw head 2 and reinforcement prism 5 associate, and the pressure for enabling three to be subject to is shared each other, while can make the intensity of three
Addition is obtained, the intensity of the utility model bolt is effectively improved.
In summary it is found that the utility model can be by cushion hole 4 and reinforcing prism can enable screw rod 1 obtain one
Fixed elasticity can buffer the external force for being applied to itself so as to bolt, thus the feelings for avoiding bolt from occurring being broken
Condition, while the elasticity can be avoided the case where being permanently deformed, and reinforce prism can not only to offset 4 bring of cushion hole strong
Degree is reduced, additionally it is possible to the intensity of screw rod 1 is further increased, it more can be by assisting screw 11 to make screw rod 1, screw head 2 and reinforcing rib
Column can promote mutual intensity, guarantee the intensity of bolt to the full extent, realize high-intensitive effect, enable using the bolt
The service performance of engine is protected.
After auxiliary screw 11 is bolted in 1 inside of screw rod, it can be pitched by the limited location fork 15 of limited block 14 in annular slot 16
It is interior, it is fixed finally by position of the butterfly screws 19 to limited block 14, to be obtained to the position of auxiliary screw 11
Fixed, when bolt shakes in engine operation process, the engaging between limited location fork 15 and annular slot 16 can have
The loosening of effect limitation auxiliary screw 11, stability when prism 5 is reinforced in guarantee, screw rod 1 is connect with screw head 2 are protected to the full extent
Demonstrate,prove the high intensity of bolt.
