Abstract
The utility model discloses an anti-loosing fastener which comprises a nut body and a screw rod body arranged above the nut body. A through hole is formed in the nut body, a hook-shaped stand column is arranged on the top portion of the nut body, a cavity is arranged in the hook-shaped stand column, threads are arranged on the bottom portion of the screw rod body, a protruding block in matched connection with the cavity is arranged above the threads, a groove in matched connection with the hook-shaped stand column is arranged above the protruding block, and a head portion is arranged on the top portion of the groove. The anti-loosing fastener is simple in structure, anti-corrosive, anti-loosing, antirust, easy to machine and produce, and low in material cost.
Description
Technical field
The utility model relates to technical field of fastening, specifically is a kind of anti-loose fastening piece.
Background technique
In technical field of fastening, connection by threaded fastener is people's common a kind of mechanical coupling modes in daily production and life, because the locking of screw thread is guaranteed by screw rod tooth and the interdental frictional force of nut, thereby under underload and under the slight vibration, can not produce between them and relatively move, but under heavy load, particularly under alternate load and horizontal vibration, member is subjected to continuously when work, vibration frequently, cause the gap between the internal and external threads to become big, frictional force between the screw thread is disappeared, caused getting loose of nut, influence its working life.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, anti-loose fastening piece easy for installation.
The utility model is achieved through the following technical solutions:
A kind of anti-loose fastening piece of the present utility model, comprise nut main body, and be arranged on the screw rod main body of nut main body top, be provided with through hole in the described nut main body, described nut main body top is provided with the column of hook-type, is provided with cavity in the column of described hook-type, described screw rod bottom part body is provided with screw thread, described screw thread top is provided with the projection that matches and be connected with cavity, and described projection top is provided with the groove that matches and be connected with the column of hook-type, and described groove top is provided with head.
Technological scheme further, described nut main body and screw rod main body are plastic material.
Technological scheme further, the column of described hook-type is the elasticity column.
The beneficial effects of the utility model are: this enforcement is simple in structure, and corrosion protection is locking, antirust safety attachment, and processing easily, the cost of material is low.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is a kind of anti-loose fastener constructions schematic representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of anti-loose fastening piece of the present utility model, comprise nut main body 5, and be arranged on the screw rod main body 8 of nut main body 5 tops, be provided with through hole 4 in the described nut main body 5, described nut main body 5 tops are provided with the column 3 of hook-type, be provided with cavity 6 in the column 3 of described hook-type, described screw rod main body 8 bottoms are provided with screw thread 7, described screw thread 7 tops are provided with the projection 9 that matches and be connected with cavity 6, described projection 9 tops are provided with the groove 2 that matches and be connected with the column 3 of hook-type, and described groove 2 tops are provided with head 1.
Wherein, described nut main body 5 is plastic material with screw rod main body 8.
The column 3 of described hook-type is the elasticity column.
The beneficial effects of the utility model are: this enforcement is simple in structure, and corrosion protection is locking, antirust safety attachment, and processing easily, the cost of material is low.
The above only is embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
