Screw thread and tapered tread；It is divided into triangle thread, rectangular thread, trapezoidal thread, saw-tooth thread by its cross sectional shape (tooth form)
And other special shape screw threads.
Cylindrical thread Zhong ﹐ triangle threads self-locking properties are good.It is divided to coarse thread and closely-pitched Liang Zhong ﹐ typically connection multi-purpose coarse thread spiral shell
Line.The Hao ﹐ of pitch little ﹐ lift angle little ﹐ self-locking properties Geng of closely-pitched, which are usually used in small part light-wall pipe Zhong ﹐, the connection of vibration or varying load
Jie ﹐ and micromatic setting etc..
Any plane is impossible to be in close contact completely, needs leakproof seal, and thread seal is also it is thus desirable to add lubrication
Agent etc., adjusting nut when in use, facilitate, good airproof performance to keep its to rotate, it is also desirable to lubricant is added to it, but typically
Adjusting nut lubricant addition it is few, the time interval of addition is short.
And existing adjusting nut is due to its good self-locking property, cause it in long-time without using there is screw thread
In the case of getting rusty, dismounting is firmly big, or even occurs being difficult situation about dismantling.
Utility model content
The technical problems to be solved in the utility model is the deficiency for more than, there is provided a kind of support frame of adjustable angle is adjusted
Nut is saved, has the storage capacity of increase lubricant, the time interval of increase addition lubricant, dismounting firmly small and convenient disassembly
Advantage.
To solve above technical problem, the utility model uses following technical scheme：
A kind of support frame adjusting nut of adjustable angle, including cylinder, the outer surface of the cylinder are provided with the first ditch
Groove, second groove and the 3rd groove；
The section of the second groove section is in isosceles trapezoid；
