Abstract

The utility model discloses an anti-falling nail, which comprises a nail cap (1) and a nail body (2). The anti-falling iron nail is characterized in that the nail body (2) is provided with a row of thin grooves (3). Connection strength of the anti-failing iron nail with wood is increased, and the iron nail can effectively avoid falling even when used for fast growing wood with loose quality.

Description

A kind of anticreep iron nail

Technical field

The utility model relates to a kind of iron nail, particularly a kind of iron nail of coming off from wood materials of preventing.

Background technique

Iron nail is a kind of connected element commonly used in people's daily life, especially for wood materials is interconnected.But because existing a lot of timber all are fast growing woods, material is comparatively loose, the iron nail that hammers into since be subjected to add the power of holding less, under external force, come off than being easier to, badly influence the performance of wood-based product.

The model utility content

The purpose of this utility model is: a kind of anticreep iron nail is provided, and it can increase the power that is connected with timber, is used for the loose fast growing wood of material and also can effectively prevents to come off.

The technical solution of the utility model: a kind of anticreep iron nail, comprise the head of a nail and nail body, it is characterized in that: the nail body is provided with row's fine groove.

In the aforesaid anticreep iron nail, the degree of depth of described fine groove is 0.2～0.5 millimeter.

In the aforesaid anticreep iron nail, described fine groove with the nail axon to becoming 30 °～45 °.

In the aforesaid anticreep iron nail, described fine groove be spaced apart 1/5th the nail body lengths.

In the aforesaid anticreep iron nail, scribble one deck water-absorbing resin in the fine groove.

Compared with prior art, the utility model is by offer fine groove on the nail body of iron nail, to hold water and air, after iron nail of the present utility model hammered into timber, the water and air in the fine groove reacted with iron nail, made the iron nail expansion of getting rusty, slip into timber firmly, make iron nail be difficult for coming off from timber.Inventor of the present utility model is by repetition test, finally determined fine groove the degree of depth and with the angle of iron nail, make fine groove under the situation that does not influence iron nail intensity, hold enough water and airs.Fine groove and iron nail nail axon to angle too small, then can reduce radial strength, bending distortion easily; And excessive difficulty of processing, the raising cost of production of then can increasing of angle.The degree of depth of fine groove also directly has influence on the capacity of nail body intensity and water and air, thereby influences the corrosion degree of iron nail.The fine groove degree of depth that the inventor finally determines and the interval of angle and fine groove, the every horizontalization of radial strength has all only reduced by 1% after testing.After iron nail of the present utility model hammers into timber, when more identical big or small common nail hammers into same timber, extract required power and increase more than 30%, effect is remarkable.For the bigger iron nail of model, in fine groove, apply one deck water-absorbing resin, can effectively increase the water content in the fine groove, deepen corrosion effect.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Being labeled as in the accompanying drawing: the 1-head of a nail, 2-follows closely body, 3-fine groove.

Embodiment

A kind of anticreep iron nail comprises the head of a nail 1 and nail body 2, it is characterized in that: nail body 1 is provided with row's fine groove 3.The degree of depth of described fine groove 3 is 0.2～0.5 millimeter.Described fine groove 3 axially becomes 30 °～45 ° with nail body 2.Described fine groove 3 be spaced apart 1/5th nail bodies 2 length.

Preferred version: a kind of anticreep iron nail, comprise the head of a nail 1 and nail body 2, it is characterized in that: nail body 1 is provided with row's fine groove 3.The degree of depth of described fine groove 3 is 0.3 millimeter.Described fine groove 3 axially becomes 35 ° (∠ α) with nail body 2.Described fine groove 3 be spaced apart 1/5th nail bodies 2 length.Scribble one deck water-absorbing resin in the fine groove 3.

Using method: before hammering into anticreep iron nail of the present utility model,, can replace with saliva when anhydrous with water-soaked nail body 2 (all fine grooves 3 soak into the position).After hammering into, make its slowly corrosion get final product, after the water and airs in the fine groove 3 used up, iron nail stopped corrosion naturally.

Claims
