Abstract
The utility model provides an alloy anti-loosening screw pair and aims to solve the technical problem that when the bolt is applied to the vibration place, the screw pair begins to loose after a period of time, thereby bringing about the accident potential. In the prior art, the bolt and the nut are stuck together via an adhesive or the bolt and the nut are riveted together, thereby resulting in that the bolt and the nut are only used for one time. The technical scheme of the alloy anti-loosening screw pair is as follows: an anti-loosening layer with high friction coefficient coats the threads of the nut or the bolt or the threads of the nut and the bolt. The alloy anti-loosening screw pair is applied to the bolts, the nuts or the connection fasteners with screw pair (such as bolts and nuts).
Description
Technical field
The utility model relates to a kind of link of being made up of screw pair, such as chek bolt.
Background technique
Bolt is as a kind of connection fastening piece, and the application is very extensive.When being applied to the oscillator field composition and division in a proportion as the time,, produce accident potential with occurring loosening phenomenon after a while as the rail joint bolt and nut.Prevent that at present the main practice of becoming flexible from being, use binding agent that screw bolt and nut is bonding, or with the screw bolt and nut riveted joint, it is disposable that these schemes cause bolt and nut to become.
Summary of the invention
For overcoming the deficiency of prior art, the purpose of this utility model is to provide a kind of alloy checknut pair.
The purpose of this utility model is achieved in that fills the big material of friction factor as locking layer between screw pair.It is by increasing the area of contact and the locking layer that has utilized the high coefficient of friction material between screw pair, improving the self-lock ability of screw pair.
The utility model compared with prior art, its advantage is:
1, locking reliable.According to " fastening piece transverse vibration test method is carried out anti-loosening property and detected, and remaining axle power/primitive axis power is minimum to be 81.4%, on average reaches 86.7%.
2, can repeated disassembled and assembled, repeatedly use anti-loosening property not subtract, easily promote the use of.
3, most locking layers have antiseptic property, so the utility model also has antiseptic property, increase the service life.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is the bolt and nut schematic representation.
Fig. 2 is an I portion enlarged view among Fig. 1.
Embodiment
Said screw pair can be the connection fastening piece of threaded pairs such as bolt and nut or screw-nut.Accompanying drawing is bolt 2 nuts 1.On the screw thread of nut or bolt, be coated with the big a kind of alloy material of one deck friction factor as locking layer 3.Also can be on the screw thread of nuts and bolt, to be coated with the big a kind of alloy material of one deck friction factor simultaneously as locking layer 3.
Claims (2)
1, a kind of alloy checknut pair has screw pair, it is characterized in that: fill locking layer between screw pair.
2, according to the described alloy checknut of claim 1 pair, it is characterized in that: scribbling one deck alloy material on the screw thread of nut or bolt or on the screw thread of nuts and bolt as locking layer.
