CN2646294Y - Quincuncial convex thorn sticker kneed hook type guard net - Google Patents

Abstract

The utility model relates to the guard net field, which comprises an iron core wire and stationary convex thorns (arranged on the core wire) at regulated interval; wherein, the convex thorns which are quincuncial connective metal strip made of plate (carbon or corrosion resistant plate) with a plurality of acuminate quincuncial wing panel. A guard net of the quincuncial convex thorn is formed by the iron core wire covered with the convex thorn connected metal strip. As the connection part being the wing panel pontes of the convex thorn fixed on the iron core, the connection between iron core and the convex thorn is extremely firm; the utility model has the advantage of strong protection and long life-span.

Description

The protruding thorn sharp knife of quincunx returns the hook protective screening

Technical field

The utility model relates to a kind of protective screening field.

Background technology

Existing protective screening mostly is that materials are simple on the market, and the thorn spacing is too big, and easily climbing of back is installed, and protective capacities is relatively poor; Because materials is less demanding, therefore get rusty easily, shortened application life.

Summary of the invention

The utility model is exactly to make improvements for the problems referred to above that solve existing protective screening existence, and its purpose is to provide a kind of protective capacities strong, robust protective screening.

In order to achieve the above object, the technical solution adopted in the utility model is: protruding thorn of blossom type and sharp knife matrix return the hook protective screening, its protruding thorn is the combination with symmetrical spike group of a plurality of predetermined distances of being separated by, the steel band that the centre is left is used for the clad metal heart yearn, has so just formed the finished product of protective screening.It is to form after the punching press by the upper end of sharp knife fin to leave the shape that two matrixs return the hook sharp knife that the sharp knife matrix returns the hook protective screening, and this has just formed the sharp knife matrix and has returned the hook protective screening.This protruding thorn is that this coupling part and fin are covered by on the metal core wire then by the fin and the coupling part that is connected with this fin of a plurality of sharp knives, spike shape corner angle.

The utility model protective screening adopts heat zinc coating plate to combine with the galvanizing high-carbon steel wire and corrosion resistant plate combines with stainless steel wire.Because protruding thorn is coated on this metal wire rod, the comparatively robust that combines of metal wire rod and protruding thorn, so protective capacities is strong, long service life.

Description of drawings

Fig. 1 is a floor map of the present utility model;

Fig. 2 is a floor map of the present utility model;

Fig. 3 is the side schematic view of Fig. 1.

The specific embodiment

As shown in Figure 1, the label 1 among Fig. 1 is this metal core wire, and label 2 is the metal sheet fins that are coated on the protruding thorn of blossom type on this metal core wire, and label 3 is the also coating finished products of clad metal heart yearn 1 that are connected with fin 2.

The diameter of metal core wire 1: the requirement of strength according to constituting protective screening can change between 2.5-3.0MM; The heart yearn material can be high-carbon steel wire or stainless steel wire, also available other wires.

Fin 2: be made up of the protruding thorn of a plurality of symmetrical spike shapes or the protruding thorn type fin that returns hook of sharp knife shape concavity is formed for every group, its thickness is 0.4-2MM.As steel plate less than 0.4MM, insufficient strength; As greater than 2MM, cost is too high.

The big I of fin 2 changes with its shape and user's needs, and the length 1 of fin can be 24-75MM, as shown in Figure 1 and Figure 2:

2 is the cutter spacing among Fig. 1, Fig. 2, as required usually between 40-130MM;

2 is that cutter is wide among Fig. 1, Fig. 2, as required usually between the 18-30MM;

P is a heart yearn among Fig. 1, Fig. 2, as required usually between 2.5-3.0MM;

F is a steel plate thickness among Fig. 1, Fig. 2, as required usually between 0.4-2.0MM;

According to the described specification of Fig. 1, Fig. 2, when producing, can change the shape of fin according to user's needs.

Claims (4)

1. protruding thorn of blossom type and sharp knife type matrix return the hook-type gill net, comprise on metal core wire and the heart yearn protruding thorn every predetermined distance, it is characterized in that, be to be coated on a kind of protective screening that forms on this metal core wire with fin and coupling part respectively by high-carbon steel wire and carbon steel sheet or corrosion resistant plate and stainless steel wire.

2. protruding thorn of blossom type according to claim 1 and sharp knife type matrix return the hook-type gill net, it is characterized in that blossom type: two plum blossoms are protruding thorns of spike type (protruding as required thorn energy multipotency is few) of symmetry; Sharp knife type matrix returns the hook fin, because sharp knife is long, so recessed two ends, the centre of sharp knife have two anti-anchors that return hook again.

3. protruding thorn of blossom type according to claim 1 and sharp knife type matrix return the hook-type gill net, it is characterized in that, the putting in order of fin of projection is: in the monosymmetric configuration of metal core wire.

4. protruding thorn of blossom type according to claim 1 and sharp knife type matrix return the hook-type gill net, it is characterized in that, the feature of material is that metal core wire is to be made by carbon steel line, stainless steel wire; Above-mentioned various fin is made by carbon steel sheet, corrosion resistant plate.
