Abstract
The utility model discloses a special tree sign nail. The special tree sign nail comprises a nail cap (1) and a nail rod (2), wherein the nail cap is elliptical, the long axle of the nail cap is 2.5cm and is arc-shaped, and the short axle of the nail cap is 1.5cm; the nail rod is conical or pyramidal, and the ratio of the base diameter to the nail rod length is 1:(10-15); the height H of the nail rod (2) is 40-50mm. The special tree sign nail can grow synchronous to a tree trunk. By using the special tree sign nail, the nail and a sign are prevented from being submerged into the tree trunk along with the thickening of the tree trunk. The special tree sign nail is reasonable in design, easy to machine, convenient to operate, low in cost and easy to popularize.
Description
Technical field
The utility model relates to a kind of nail, particularly relates to a kind of tree board nail.
Background technique
In ancient tree protection propaganda work, often will on tree bar, with tree board nail, order tree board (irony), along with the bars of growing up, set of trees increases slightly, tree board nail and tree board all can fall into into tree bar, and tree board nail puller does not go out, and impact sets that bar is grown, the use of timber and attractive in appearance.
The xylem at the girth growth Bu Shi center of trees, outwards increases thick from timber portion surface.After tree board nail is ordered xylem, by wooden, hung on to, can not exit, and the continuous outwards increasing of wood surface is thick, tree board is followed closely and will be sunk deeper and deeper, final, and iron nail, iron board are absorbed in xylem.Want to set board nail, tree board does not fall into into tree bar (xylem), just essentially meets tree board nail and the synchronous growth of tree bar, therefore, need to meet 1 condition.That sets board nail and tree bar (xylem) simultaneously outside " length " exactly.Solve this, only have two ways, tree board nail can not be held too tightly by tree bar, and tree board nail can " retreat ".
Model utility content
Technical problem to be solved in the utility model is to provide a kind of energy with the tree board nail of tree bar synchronous growth.
In order to solve the problems of the technologies described above, the tree board nail that the utility model provides, comprises the head of a nail and nail bar, and described nail bar is that cone-shaped nail bar and described cone-shaped nail bar height dimension H are 40 ㎜～50 ㎜.
The described head of a nail is oval, and its major axis is 2.5cm, arc; Minor axis is 1.5cm.
The diameter of the described head of a nail is 10～15:1 with the diameter ratio of described cone-shaped nail bar.
The taper of described cone-shaped nail bar is taper shape or pyramid shape.
Adopt the tree board nail of technique scheme, reduced the length of nail bar, reduce the wooden grip to tree board nail, nail bar is a thick thin cone-shaped nail bar, is convenient to retreat; The size, the head of a nail major axis that strengthen the head of a nail are arc, can laterally coincide with tree bar, increase reaction force lifting surface area, thereby reach the effect of " nail pulling ".The utility model is reasonable in design, be easy to construction, easy to operate, cost is low, be easy to promote.
In sum, the utility model be a kind of energy with tree bar synchronous growth and reasonable in design, be easy to construction, easy to operate, cost is low, be easy to the tree board nail promoted.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is generalized section of the present utility model.
Fig. 3 is use view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1 and Fig. 2, the head of a nail 1 is oval, and its major axis is 2.5cm, arc; Minor axis is 1.5cm.The head of a nail 1 is provided with cone-shaped nail bar 2 and cone-shaped nail bar 2 height dimension H are 40 ㎜～50 ㎜, and the taper of cone-shaped nail bar 2 is taper shape or pyramid shape.The diameter of the head of a nail 1 is 10～15:1 with the diameter ratio of cone-shaped nail bar 2.
Referring to Fig. 1 and Fig. 2, tree board nail 5 is ordered tree board 4 nails in ancient tree protection propaganda work on trees 3.Cone-shaped nail bar 2 height dimension H are 40 ㎜～50 ㎜, have reduced the length of nail bar of the tree board nail of current use, reduce the wooden grip to the nail bar of tree board nail, and nail bar is a thick thin cone-shaped nail bar 2, is convenient to retreat; The size that strengthens the head of a nail 1, head of a nail major axis is arc, can laterally coincide with tree bar, increases reaction force lifting surface area, thereby reaches the effect of " nail pulling ".Along with the bars of growing up, set of trees 3 increases slightly, tree board nail 5 and tree board 4 can not fall into into tree bar, and tree board nail 5 can be extracted, and do not affect the use of the growth of tree bar, timber and attractive in appearance.
The utility model is reasonable in design, be easy to construction, easy to operate, cost is low, be easy to promote.
