Abstract
The utility model relates to a kind of studs, including double threaded screw, the both ends of double threaded screw are equipped with screw thread, and the end of screw rod is arranged nut, and the middle part of the nut is equipped with threaded hole, threaded hole is engaged with the screw thread of screw rod end, nut has upper surface, lower surface and circumferential surface, and the circumferential surface of nut is equipped with oil filler point, the inside of the nut is equipped with the annular oil inlet passage being connected to oil filler point, and the lower surface of nut is equipped with multiple oil outlets being connected to annular oil inlet passage.After nut is connect with double threaded screw, lubricating oil is injected from the oil filler point of nut circumferential surface, lubricating oil is entered in annular oil inlet passage and is flowed out from multiple oil outlets, it is located at the lower surface of nut due to multiple oil outlets and uniformly arranges in the outside of threaded hole, the lubricating oil of outflow is the effect that can reach lubrication from the contact surface position of nut and double threaded screw and thread contact, improves lubricant effect.
Description
Technical field
The utility model relates to fastener areas, especially a kind of stud.
Background technique
Stud is also double-threaded screw or studs.For connecting mechanical fixed-link function, stud two
Head has a screw thread, intermediate screw rod, have it is thick also have it is thin.It is generally used for mining machinery, bridge, automobile, motorcycle, boiler steel
Structure, tower crane, large-span steel and heavy construction etc. can be applied to large-scale stud on some large scale equipments, double
Hook bolt needs periodic maintenance and lubrication after being fastenedly connected, and guarantees that screw thread normally engages, the position for preventing screw thread from engaging is raw
Rust is stuck, 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, lubrication
Effect is bad.
Utility model content
Purpose of the utility model is to solve defects of the existing technology, provide a kind of stud.
To achieve the goals above, the technical solution adopted in the utility model is:
The both ends of a kind of stud, including double threaded screw, double threaded screw are equipped with screw thread, and the end of screw rod is arranged nut,
The middle part of the nut is equipped with threaded hole, and threaded hole engages with the screw thread of screw rod end, nut with upper surface, lower surface and
Circumferential surface, the circumferential surface of nut are equipped with oil filler point, and the inside of the nut is equipped with the annular oil inlet passage being connected to oil filler point, nut
Lower surface be equipped with multiple oil outlets being connected to annular oil inlet passage.
A kind of above-mentioned stud, multiple oil outlets are uniformly arranged in the outside of threaded hole.
A kind of above-mentioned stud, end annular arrangement of multiple oil outlets in double threaded screw.
A kind of above-mentioned stud, the annular oil inlet passage is the sealed passage being arranged in nut.
A kind of above-mentioned stud, the nut are hex nut.
The utility model has the following beneficial effects: the circumferential surface of the nut of the stud is equipped with oil filler point, the nut
Inside is equipped with the annular oil inlet passage that be connected to oil filler point, and the lower surface of nut is connected to equipped with multiple with annular oil inlet passage
Oil outlet, multiple oil outlets are uniformly arranged in the outside of threaded hole, after nut is connect with double threaded screw, from the oiling of nut circumferential surface
Lubricating oil is injected in hole, and lubricating oil is entered in annular oil inlet passage and flowed out from multiple oil outlets, since multiple oil outlets are located at
It the lower surface of nut and uniformly arranges in the outside of threaded hole, the lubricating oil of outflow is from the contact surface position of nut and double threaded screw
It is the effect that can reach lubrication with thread contact, improves lubricant 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 nut；
Fig. 3 is the side schematic view of the utility model nut.
Specific embodiment
As shown in Figure 1 to Figure 3, the both ends of a kind of stud, including double threaded screw 1, double threaded screw 1 are equipped with screw thread 2, spiral shell
The end of bar 1 is arranged nut 3, and the middle part of nut 3 is equipped with threaded hole 4, and threaded hole 4 is engaged with the screw thread 2 of screw rod end, nut 3
With upper surface, lower surface and circumferential surface, the circumferential surface of nut 3 are equipped with oil filler point 5, and the inside of nut 3 is equipped with to be connected with oil filler point 5
The lower surface of logical annular oil inlet passage 6, nut 3 is equipped with multiple oil outlets 7 being connected to annular oil inlet passage 6.
In the utility model, multiple oil outlets 7 are uniformly arranged in the outside of threaded hole 4, and double threaded screw 1 is connect with nut 3
Afterwards, end annular arrangement of multiple oil outlets 7 in double threaded screw 1.Annular oil inlet passage 6 is that the sealing being arranged in nut is led to
Road.
After nut 3 is connect with double threaded screw 1, lubricating oil is injected from the oil filler point 5 of 3 circumferential surface of nut, lubricating oil enters ring
It is flowed out in shape oil inlet passage 6 and from multiple oil outlets 7, since multiple oil outlets 7 are located at the lower surface of nut 3 and in threaded hole 4
Outside uniformly arrange, the lubricating oil of outflow, which is contacted from the contact surface position of nut 3 and double threaded screw 1 with screw thread 2, can reach
The effect of lubrication, improves lubricant effect.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only the principles of the present invention, the utility model also has respectively on the premise of not departing from the spirit and scope of the utility model
Kind changes and improvements, these changes and improvements are both fallen in the range of claimed invention.The requires of the utility model
Protection scope defined by appended claims and its equivalent.
