Description
Technical field
The utility model relates to fastener areas, especially a kind of 12 corner bolts.
Background technique
Bolt is the cylindrical threaded fastener of adapted nut.By head and screw rod (having externally threaded cylindrical body)
One kind fastener dimerous, need to cooperate with nut, for being fastenedly connected two parts for having through-hole.This connection shape
Formula claims to be bolted, and present bolt gets rusty easily for a long time after completing to fasten work, intermittent oiling is needed to safeguard, if
If lubricating oil is added dropwise in the connecting portion of bolt, lubricating oil is not easy the position that screw thread is arrived in infiltration, and lubricant effect is bad.
Utility model content
Purpose of the utility model is to solve defects of the existing technology, provide a kind of 12 corner bolts.
To achieve the goals above, the technical solution adopted in the utility model is:
Including screw rod and the screw head of screw rod end is arranged in a kind of 12 corner bolts, and the surface of screw rod is equipped with screw thread,
The middle part of the screw rod is equipped with oiling channel, and the surface of screw rod is equipped with multiple oil outlets, and oiling channel passes through multiple oil discharge passages
It is connect with oil outlet.
The middle part of above-mentioned 12 corner bolt of one kind, screw head is equipped with and the channel attached pouring orifice of oiling.
Above-mentioned 12 corner bolt of one kind, multiple oil outlets are located at spiral shell in the surface of screw rod circumferential uniformly arrangement, oil outlet
The bottom of bar surface thread pitch.
Above-mentioned 12 corner bolt of one kind, the screw rod and screw head are integrally formed.
Above-mentioned 12 corner bolt of one kind, the pouring orifice is interior to inject lubricating oil.
The utility model has the following beneficial effects: the middle part of the screw rod of the bolt is equipped with oiling channel, the surface of screw rod is equipped with
Multiple oil outlets, oiling channel are connect by multiple oil discharge passages with oil outlet, and the middle part of screw head is equipped with to be connected with oiling channel
The pouring orifice connect, multiple oil outlets are located at the bottom of screw surface thread pitch in the surface of screw rod circumferential uniformly arrangement, oil outlet
Lubricating oil after screw rod is connect with mechanical part, injects in pouring orifice in portion, and lubricating oil enters oil discharge passage along oiling channel
And overflow from oil outlet to the thread contact with screw surface, it ensure that effectively lubricating effect.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model；
Fig. 2 is the schematic cross-section of the utility model.
Specific embodiment
As shown in Figure 1 and Figure 2, including screw rod 1 and the screw head 2 of 1 end of screw rod, spiral shell is arranged in a kind of 12 corner bolts
The surface of bar 1 is equipped with screw thread 3, and the middle part of screw rod 1 is equipped with oiling channel 4, and the surface of screw rod 1 is equipped with multiple oil outlets 5, and oiling is logical
Road 4 is connect by multiple oil discharge passages 6 with oil outlet 5.
Further, the middle part of screw head 2 is equipped with the pouring orifice 7 connecting with oiling channel 4, and multiple oil outlets 5 are in screw rod 1
The circumferential uniformly arrangement in surface, oil outlet 5 are located at the bottom in 3 gap of screw surface screw thread, and screw rod 1 and screw head 2 are integrally formed.
After screw rod 1 is connect with mechanical part, lubricating oil is injected in pouring orifice 7, lubricating oil is entered along oiling channel 4
