With barbed earth anchor
Technical field
The present invention relates to a kind of earth anchor, more precisely a kind of barbed earth anchor of band.
Background technology
Chinese utility model patent ZL91200576.9 discloses a kind of for fixing the removable building such as tent or mast
The earth anchor of object, by one block of tip steel plate, several hangnail steel wires being fixed thereon and one it is can swinging on it, be extension drawstring
Steel wire ring 3 forms.But the hangnail of this earth anchor of composition, when anchoring into earth anchor in soil, hangnail is easy to be made by soil
It firmly bends towards near its tip steel plate, cannot be preferably anchored with soil;And the process that its hangnail is pulled out in earth anchor
In be easily bent over damage, keep the service life of this earth anchor shorter.
Invention content
The present invention is mainly the technical problem solved present in the prior art, to provide a kind of falling with cone
Thorn is not easy to be bent over damage during installing and removing earth anchor, and reusable, service life is longer;Tapered end
Pit is provided on end face, during installing earth anchor, pit can play the role of tamping earth anchor ambient earth, make earth anchor
Anchor more firmly with barbed earth anchor.
The above-mentioned technical problem of the present invention is mainly to be addressed by following technical proposals:
A kind of barbed earth anchor of band, including an anchor bar, the end set of the anchor bar have a tapered end, institute
A middle part pyramidal projections are provided in the middle part of the anchor bar stated, the tail portion of the anchor bar is provided with an end cone protrusion,
Three hangnails are respectively arranged at the top of the tapered end and the middle part pyramidal projections, the hangnail is cone
Structure, side is in tilted layout the hangnail outwardly.
As preferred embodiments of the present invention, there are three pits for setting on the conical surface of the tapered end.
The advantages of band barbed earth anchor of the present invention is:Hangnail with cone, in the mistake for installing and removing earth anchor
It is not easy to be bent over damage in journey, reusable, service life is longer;It is provided with pit on the end face of tapered end, is being installed
During earth anchor, pit can play the role of tamping earth anchor ambient earth, keep the anchor of earth anchor more secured.
Description of the drawings
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
Obtain other attached drawings according to these attached drawings.
Fig. 1 is the dimensional structure diagram of the barbed earth anchor of band of the present invention;
Wherein:
1, it is anchored bar;
2, tapered end;21, pit;
3, middle part pyramidal projections;
4, end cone protrusion;
5, hangnail.
Specific implementation mode
The preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
The advantages of band barbed earth anchor of the present invention is:Hangnail with cone, in the mistake for installing and removing earth anchor
It is not easy to be bent over damage in journey, reusable, service life is longer;It is provided with pit on the end face of tapered end, is being installed
During earth anchor, pit can play the role of tamping earth anchor ambient earth, keep the anchor of earth anchor more secured.
As shown in Figure 1, a kind of barbed earth anchor of band, including an anchor bar 1, the end set of the anchor bar 1 have a cone
The middle part of shape end 2, the anchor bar 1 is provided with a middle part pyramidal projections 3, and the tail portion of the anchor bar 1 is provided with an end cone
The top of protrusion 4, the tapered end 2 and the middle part pyramidal projections 3 is respectively arranged with three hangnails 5, which is that cone is tied
Structure, side is in tilted layout the hangnail 5 outwardly.During installing or removing earth anchor, the side institute of the hangnail 5 of this cone
The power being subject to is smaller, and conical structure itself is also more difficult to be bent over, therefore this hangnail 5 is very unlikely to be damaged, and makes this band
The service life of barbed earth anchor is longer.
There are three pits 21 for setting on the conical surface of the tapered end 2, although this pit 21 can increase this earth anchor of installation
When difficulty, but also have the function of tamp earth anchor around soil, so that earth anchor is anchored in more solid soil, because
This anchor is more secured.
The mentality of designing of the above some embodiments for being only the present invention, in the case where system allows, the present invention can
To be extended to while external more function modules, to extend its function to greatest extent.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection domain should be determined by the scope of protection defined in the claims.
