Abstract
The utility model relates to a kind of nuts being readily disassembled, including nut body, on the outer ring screw thread of nut body one or both sides, are equipped with multiple openings, make to form multiple teeth on the screw thread of outer ring, the hand of spiral inclination of the opening threadingly.The opening depth is consistent with thread height.Threadingly the hand of spiral is gradually increased the width of the opening and teeth since screw thread starting point.The quantity of the opening is 4-12.The bevel edge of the teeth and the tangent line angle of teeth cusp helix are teeth wedge angle B, and teeth wedge angle B is 30-75 °.The utility model structure is simple, when nut dismounting, can remove the sundries adhered on screw rod, disassembly is freely.Suitable for outdoor engineering machinery, mining machinery, farm machinery, in water and the bolt of the exposed vulnerable to pollution under external environment.
Description
Technical field
The utility model relates to fastener, in particular to a kind of nut being readily disassembled.
Background technique
When bolt is used for outdoor engineering machinery, mining machinery, farm machinery is in water and exposed under external environment, easily contacts
Sundries, sundries are attached on screw rod, and nut dismounting is highly difficult.The application designs a kind of spiral shell being readily disassembled regarding to the issue above
It is female.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of nuts being readily disassembled, and can remove on screw rod and adhere to
Sundries, disassembly freely.
To achieve the above object, the utility model is implemented with the following technical solutions:
A kind of nut being readily disassembled, including nut body are equipped on the outer ring screw thread of nut body one or both sides
Multiple openings make to form multiple teeth on the screw thread of outer ring, the hand of spiral inclination of the opening threadingly.
The opening depth is consistent with thread height.
Threadingly the hand of spiral is gradually increased the width of the opening and teeth since screw thread starting point.
The quantity of the opening is 4-12.
The bevel edge of the teeth and the tangent line angle of teeth cusp helix are teeth wedge angle B, and teeth wedge angle B is 30-
75°。
Compared with prior art, the beneficial effects of the utility model are:
The utility model structure is simple, when nut dismounting, can remove the sundries adhered on screw rod, disassembly is freely.It is suitable for
Outdoor engineering machinery, mining machinery, farm machinery, in water and the bolt of the exposed vulnerable to pollution under external environment.
Detailed description of the invention
