Abstract
This utility model belongs to technical field of fastening, particularly relate to a kind of threaded anti-loose structure, it is made up of connection screw rod, nut, holding screw, it is characterized in that: connect screw rod and be connected with nut, and fasten at nut end face holding screw, described nut cylindrical is provided with groove, and end face is provided with screwed hole and communicates with groove.It provides the benefit that: by using such scheme, produce stress after making groove both sides stress deformation set by nut cylindrical, so that nut reduces with screw flight fit clearance, cause the frictional force between nut and screw rod to increase, therefore, effectively prevent to produce between screw rod and nut and loosen.
Description
Technical field
This utility model belongs to technical field of fastening, particularly relates to a kind of threaded anti-loose structure.
Background technology
In plant equipment, the combination between parts would generally use threaded realization, but; unit is during running; owing to the temperature of parts can change, and unit also can produce certain vibration, therefore; after use after a while; therefore the Screw Thread Fit Clearance connected between screw rod and nut would generally increase, and causes connecting parts and loosens, once this thing happens; it is possible to make equipment normally to work, even causes other security incident.
Summary of the invention
This utility model is to provide a kind of threaded anti-loose structure to solve the problems referred to above.
Scheme of the present utility model is achieved in that a kind of threaded anti-loose structure, it is made up of connection screw rod, nut, holding screw, it is characterized in that: connect screw rod and be connected with nut, and fasten at nut end face holding screw, described nut cylindrical is provided with groove, and end face is provided with screwed hole and communicates with groove.
The beneficial effects of the utility model are: by using such scheme, stress is produced after making groove both sides stress deformation set by nut cylindrical, so that nut reduces with screw flight fit clearance, the frictional force between nut and screw rod is caused to increase, therefore, effectively prevent to produce between screw rod and nut and loosen.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
In figure: 1, nut, 2, holding screw, 3, connect screw rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described:
A kind of threaded anti-loose structure as shown in Figure 1, it is made up of connection screw rod 3, nut 1, holding screw 2, connects screw rod 3 and be connected with nut 1, and use holding screw 2 to fasten at nut 1 end face, described nut 1 cylindrical is provided with groove, and end face is provided with screwed hole and communicates with groove.By using such scheme, produce stress after making groove both sides stress deformation set by nut cylindrical, so that nut reduces with screw flight fit clearance, cause the frictional force between nut and screw rod to increase, therefore, effectively prevent generation between screw rod and nut and loosen.
