Side be provided with dimpled grain, there is inner core head in bolt head center, and the inner core head protrudes from the upper surface of bolt head, and the inner core
Rostral face is provided with prominent head, and the inside screw is provided with inner core, and the inner core lower end protrudes from the lower surface of screw rod, institute
It states screw rod lower end side and is provided with elastic rod.At present, the bolt of the fixation street lamp used on the market, fixed effect are not special
Substantially, fixed unstable, the event that street lamp is caused to be toppled over occurs during use often, so the utility model provides a kind of use
In the bolt of fixed street lamp, including bolt head, screw rod, inner core, the bolt head is cylinder, and the side of bolt head is provided with recessed
There is inner core head in line, bolt head center, by setting inner core head inside bolt, make it is bolt strained uniformly, be subject to ectocine
When be not susceptible to loosen.The inner core head protrudes from the upper surface of bolt head, and the inner core head side is provided with prominent head, dashes forward
Lifting one's head can be easy to disassemble,, can be by prominent head come first when moving street lamp if necessary to demounting bolt during use
Inner core is loosened, bolt head is further turned, if inner core does not loosen, bolt head can not be turned, it is further to increase
The strong firm ability of bolt.The inside screw is provided with inner core, and the inner core lower end protrudes from the lower surface of screw rod, institute
It states screw rod lower end side and is provided with elastic rod, elastic rod is identical with screw rod radius when screwing in, after being completely screwed into, elasticity
Bar will protrude, and catch on the both sides for screwing in object, effectively accomplished securely, to be not easy to loosen, greatly extend bolt
Service life.When needing to pop up inner core, inner core head need to be only pressed, rotates prominent head, it is simple and convenient, it is highly practical.
Further, a kind of for fixing the bolt of street lamp, the screw thread that the screw surface is set from top to bottom get over by density
Come smaller.By the screw thread that sets screw surface, density is less and less from top to bottom, can preferably increase the stabilization of bolt
Property, the screw thread caused by friction is avoided to come off, frictional force reduces, and easily loosens, and the screw thread that screw surface is set is from top to bottom
Density is less and less, effectively screw thread can be avoided to come off because of friction.
Further, a kind of for fixing the bolt of street lamp, the number of the protrusion head is 2, is symmetrically distributed in inner core
The side of head.Using two prominent heads, it is easy to rotate in demounting bolt.
Further, a kind of for fixing the bolt of street lamp, the number of the elastic rod is 2, is symmetrically distributed in inner core
The face of lower end.By two elastic rods, screw-in object can be preferably caught on, increases stability.
Further, a kind of for fixing the bolt of street lamp, the depth of the dimpled grain is 5mm.Use the depth of dimpled grain for
5mm, it is convenient to have an effect when screwing in, avoid bolt head is excessively smooth from can not tightening.
Further, a kind of for fixing the bolt of street lamp, length is more than the straight of screw rod when the elastic rod pops up completely
Footpath, length is more than the diameter of screw rod when only elastic rod pops up completely, could will screw in object and catch on, the fixation of street lamp is made more to step up
Gu street lamp is not susceptible to topple over.
In summary, the following advantageous effect of the utility model：
1st, the utility model is a kind of for fixing the bolt of street lamp, and screw rod lower end side is provided with elastic rod, elastic rod
After screw rod is completely screwed into, elastic rod will protrude, and catch on the both sides for screwing in object, effectively accomplished securely, to be not easy pine
It is dynamic
2nd, the utility model is a kind of for fixing the bolt of street lamp, by setting inner core head inside bolt, make bolt by
Power is uniform, is not susceptible to loosen when being subject to ectocine
3rd, the utility model is a kind of for fixing the bolt of street lamp, when needing mobile street lamp demounting bolt by inner core bullet
Go out, need to only press inner core head, rotate prominent head, it is simple and convenient, it is highly practical
