Abstract

The utility model discloses a kind of anti-skid screw, comprise screw cap (1) and screw rod (2); Tapering transition section (3) is set between described screw cap (1) and screw rod (2); Described screw rod is cylindrical shape; Described taper changeover portion (3) is frustum shape, and the larger bottom surface of described frustum is connected on screw cap (1), and the less bottom surface of described frustum is connected on described screw rod (2); Described taper changeover portion is provided with fin (4), and described fin is formed by the rat of described taper changeover portion.The utility model screw cap arranges taper changeover portion, and has fin structure, can realize effect that is anti-skidding and increase pretightening force.

Description

A kind of anti-skid screw
Technical field
The utility model belongs to five metals part field, particularly, the utility model relates to a kind of anti-skid screw.
Background technique
Screw is one of conventional link, and Main Function is fastenedly connected by two connected pieces.Existing screw, when connecting connected piece, needs to adopt packing ring to carry out anti-skidding usually.But this mode is not only complicated, and reduces working efficiency.
Model utility content
For the deficiency that prior art exists, technical problem to be solved in the utility model is to provide a kind of anti-skid screw.The utility model screw cap arranges taper changeover portion, and has fin structure, can realize effect that is anti-skidding and increase pretightening force.
It is realize by the following technical solutions that the utility model solves the problems of the technologies described above:
A kind of anti-skid screw, comprises screw cap and screw rod; Tapering transition section is set between described screw cap and screw rod; Described screw rod is cylindrical shape; Described taper changeover portion is frustum shape, and the larger bottom surface of described frustum is connected on screw cap, and the less bottom surface of described frustum is connected on described screw rod; Described taper changeover portion is provided with fin, and described fin is formed by the rat of described taper changeover portion.
Described screw cap is circular, and the radius of described screw cap is greater than the cross sectional radius of described screw rod.
The radius of the larger bottom surface of described taper changeover portion is less than the radius of described screw cap, and is greater than the cross sectional radius of described screw rod; The cross sectional radius equaling described screw rod compared with handle radius surface of described taper changeover portion.
Described fin distributes at the surface uniform of described taper changeover portion.
The height of projection of described fin is from the small end of described taper changeover portion to holding progressive additive greatly.
The quantity of described fin is 5.
Compared with prior art, the beneficial effect had is the utility model: the utility model screw cap arranges taper changeover portion, and has fin structure, can realize effect that is anti-skidding and increase pretightening force.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of embodiment 1.
The component names that in figure, each reference character is corresponding is: 1-screw cap; 2-screw rod; 3-tapering transition section; 4-fin.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
Embodiment 1
A kind of anti-skid screw, comprises screw cap 1 and screw rod 2; Between described screw cap 1 and screw rod 2, tapering transition section 3 is set; Described screw rod is cylindrical shape; Described taper changeover portion 3 is frustum shape, and the larger bottom surface of described frustum is connected on screw cap 1, and the less bottom surface of described frustum is connected on described screw rod 2; Described taper changeover portion is provided with fin 4, and described fin is formed by the rat of described taper changeover portion.
Described screw cap 1 is circular, and the radius of described screw cap is greater than the cross sectional radius of described screw rod.The radius of the larger bottom surface of described taper changeover portion 3 is less than the radius of described screw cap 1, and is greater than the cross sectional radius of described screw rod 2; The cross sectional radius equaling described screw rod 2 compared with handle radius surface of described taper changeover portion 2.Described fin 4 distributes at the surface uniform of described taper changeover portion 3.The height of projection of described fin 4 is from the small end of described taper changeover portion 3 to holding progressive additive greatly.The quantity of described fin is 5.
Embodiment 2
The present embodiment is substantially the same manner as Example 1, and its difference is only, the height of projection of described fin 4 remains unchanged from the small end of taper changeover portion 3 to large end.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
