Abstract

The utility model discloses an anti-skidding eccentric U-shaped nail which comprises a U-shaped nail body and eccentric nail points which are positioned at two top ends of a U-shaped opening of the nail body, wherein a row of narrow grooves are arranged at both sides of the nail body. The depth of the narrow grooves is 0.2-0.5 mm. The included angle formed between the narrow grooves and a shaft of the nail body is in the range of 60-90 degrees. The nail is an iron nail; and the surface of the iron nail is galvanized. In the anti-skidding eccentric U-shaped nail, a row of the narrow grooves are arranged on the surface of the smooth nail body so that the contact surface between the nail body and a nailed object is increased so as to prevent the looseness from occurring between the nail and the nailed object due to the vibration of the road surface and ensure the fixation effect.

Description

Anti-skidding step U sprig

Technical field

The utility model relates to a kind of nail, especially a kind of anti-skidding step U sprig.

Background technique

Nail is a kind of connected element commonly used in people's daily life, and the U sprig is generally used for two parts are connected into an individuality, as is used to connect backplate or guardrail on the expressway.As shown in Figure 1, the anti-skidding step U sprig of existing technology comprises the smooth nail body 1 of U type and the nail point 2 of the partial-that is positioned at nail body U type mouth two tops.

But the nail body 1 of existing technology is generally the smooth surface of round roller shape, and in the time of after hammering into thing, because the vibrations on road surface, smooth surface can make nail and hammer into to produce between the thing becomes flexible, and influences fixed effect.

The model utility content

The utility model technical problem to be solved is, provides a kind of and increase stiction, prevents the anti-skidding step U sprig that becomes flexible.

In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of anti-skidding step U sprig, comprise the nail body of U type and the nail point of the partial-that is positioned at nail body U type mouth two tops, and the nail in both sides is provided with row's fine groove on one's body.

The degree of depth of said fine groove is the 0.2-0.5 millimeter.

Said fine groove becomes 60 °-90 ° with nail body axle.

Said nail is an iron nail, the plating zinc on surface of iron nail.

The beneficial effect of the utility model is: smooth nail body surface is provided with row's fine groove, has increased and the surface of contact that hammers into thing, prevent to guarantee fixed effect because the vibrations on road surface make nail and hammer into to produce between the thing and become flexible.

Description of drawings

Fig. 1 is the schematic representation of the anti-skidding step U sprig of existing technology.

Fig. 2 is the schematic representation of the anti-skidding step U sprig of the utility model.

Fig. 3 is the schematic representation of another anti-skidding step U sprig of the utility model.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain:

Like Fig. 2, shown in 3, the anti-skidding step U sprig of the utility model comprises the nail body 3 of U type and the nail point 4 of the partial-that is positioned at nail body U type mouth two tops, on the nail body 3 of both sides, is provided with row's fine groove 5.

According to the difference of nail length, the degree of depth of said fine groove 5 is selected the 0.2-0.5 millimeter for use.Difference as required, fine groove 5 becomes 60 °-90 ° with nail body axle.

Common said nail is an iron nail, the plating zinc on surface of iron nail.

The anti-skidding step U sprig of the utility model is provided with row's fine groove with smooth nail body surface, has increased and the surface of contact that hammers into thing, prevents to guarantee fixed effect because the vibrations on road surface make nail and hammer into to produce between the thing and become flexible.

In sum; The content of the utility model is not confined in the above embodiments; Knowledgeable people in the same area can propose other embodiment easily within technological guidance's thought of the utility model, but this embodiment is included within the scope of the utility model.
