Description

Scale formula inoxidizing coating and armguard

Technical Field

The invention relates to the technical field of protective tools, in particular to a scale-type protective layer and a protective arm.

Background

The armguard is a police protective equipment commonly used by policemen in the daily duty-on process, and is used for preventing the arms of the policemen from being injured when encountering edge tools. The existing armguard is divided into a cutting-proof armguard and a armor-type armguard. The anti-cutting guard arm is formed by extending and processing according to the tissue structure of an anti-cutting glove and mainly formed by weaving Kevlar and steel wires or ultra-high molecular weight polyethylene and steel wires, and not only is the wearing comfort poor, but also the impact resistance and the buffering capacity are weak. The armor type armguard is thick and heavy, is mainly used for targeted anti-riot work, is not beneficial to being worn by policemen in the daily duty process, and is difficult to play a role in sudden violent behaviors encountered by the policemen.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the conventional anti-cutting guard arm is poor in wearing comfort and weak in impact resistance and buffering capacity; the conventional armor type armguard has heavy weight and is inconvenient to wear. The invention provides a scale type protective layer and a guard arm for solving the problems, which have the advantages of blocking function, light weight and easy wearing, can meet daily on-duty wearing requirements of policemen, and can effectively improve the protective capability of the policemen.

The invention is realized by the following technical scheme:

a scale-type protective layer comprises a plurality of units, wherein each unit comprises an upper-layer subunit and a lower-layer subunit which are arranged in an up-down layered manner; the upper layer subunit comprises three Lelo triangular scales, and the lower layer subunit comprises three Lelo triangular scales; the Lelo triangular scales of the upper subunit and the lower subunit can move relatively; in the fully overlapped state: in the overlooking direction, the Lelo triangular scales of the upper subunit and the Lelo triangular scales of the lower subunit are sequentially and alternately distributed, six Lelo triangular scales are distributed in an annular array, the tops of the six Lelo triangular scales point to the center of the annular array, and projections between adjacent Lelo triangular scales are overlapped; in the fully deployed state: in the overlooking direction, the Lelo triangular scales of the upper subunit and the Lelo triangular scales of the lower subunit are sequentially and alternately distributed, six Lelo triangular scales are distributed in an annular array, the tops of the six Lelo triangular scales point to the center of the annular array, and the projections between the adjacent Lelo triangular scales are not overlapped; in the top view direction, two adjacent Lelo triangular scales are shared between the adjacent units.

The protective layer provided by the invention is composed of a plurality of repeating units, namely a plurality of units with the same structure and size, each unit is provided with an upper layer subunit and a lower layer subunit, and the Lelo triangular scale of the upper layer subunit is positioned above the Lelo triangular scale of the lower layer subunit. In the overlooking direction, in a completely unfolded or completely overlapped state (the complete overlap refers to a final state that the scale of the upper subunit and the scale of the lower subunit can be overlapped, and does not necessarily refer to a state that the upper subunit and the lower subunit are completely overlapped, namely only three scales are projected in the overlooking direction), the Lelo triangular scales of the upper subunit and the Lelo triangular scales of the lower subunit are alternately distributed in sequence, namely the Lelo triangular scale of the upper subunit is arranged between the Lelo triangular scales of any two lower subunits. In addition, there is a superposition portion between each unit, and two adjacent lyocell triangular scales are shared between adjacent units, that is, a lyocell triangular scale sharing an upper-layer subunit between any one unit and the adjacent unit is also a lyocell triangular scale of a lower-layer subunit adjacent to the one unit. In the process from the overlapping state to the unfolding state, or from the unfolding state to the overlapping state, if uneven stress exists, the arrangement of the six Lelo triangular scales in the unit is pulled and deformed, and a non-annular array form may occur.

Through the relative movement between the Lelo triangular scales of the upper-layer subunit and the Lelo triangular scales of the lower-layer subunit, the ring array of each unit can be enlarged (shown as the area of the protective layer is expanded) or reduced (shown as the area of the protective layer is reduced) through the relative movement, the whole protective layer has ductility, and the flexibility can be increased to a large extent. Therefore, the protective layer provided by the invention has a double-layer protective function because the Lelo triangular scales of the upper subunit and the Lelo triangular scales of the lower subunit in the unit are in a superposed state under the conventional condition, can be elastically expanded along with attached cloth when necessary, improves the comfort and flexibility and is convenient to wear.

Ideally, the moving direction of each rillo triangular scale under the action of external force (e.g. pulling force generated when the protective layer is worn on the corresponding part of the human body) is as follows: from the geometric center of the annular array to the direction of the straight line between the corresponding Lelo triangular scales, the Lelo triangular scales linearly reciprocate in the direction, and therefore the increase or decrease of the outer diameter of the annular array is achieved.

More preferably, the diameter of the Lelo triangular scale is 20mm-50mm, and the thickness is 1mm-2 mm.

Further preferably, the Lelo triangular scales are made of high molecular weight polyethylene materials.

The high molecular weight polyethylene material has both light weight and protective performance, and can avoid the pain points without actual combat caused by the heaviness of the existing rigid arm protector; other materials with light weight and good protective performance can be adopted to replace the high molecular polyethylene material.

Preferably, the bottom surface of the Lelo triangular scale is provided with a magic tape for adhering to the surface of clothes.

The scales can be fixed in the area to be protected by sewing, bonding and other modes. According to the invention, the magic tapes are preferably designed to be pasted on the bottom surfaces of the scales, and the modular structure can be partially replaced while the comfort is considered through the combination of the magic tapes and the material with the magic tape hair side structure, so that the individual difference is met and the maintenance cost is reduced.

Preferably, the bottom surface of the lolo triangular scale of the upper subunit is provided with a stop block, and a step surface between the stop block and the bottom surface of the lolo triangular scale is used for limiting the size of a relative overlapping area between the lolo triangular scale of the upper subunit and the lolo triangular scale of the lower subunit.

Because the Lelo triangular scale of the upper-layer subunit and the Lelo triangular scale of the lower-layer subunit can move relatively, the upper-layer subunit and the lower-layer subunit can be freely unfolded and overlapped, and in order to prevent the upper-layer subunit and the lower-layer subunit from being excessively overlapped to cause uneven surface and disordered structure of the whole protective layer and influence the attractiveness and defense performance, a stop block is arranged on the bottom surface of the Lelo triangular scale of the upper-layer subunit. For the structural design of the stop block, three stop blocks can be independently arranged on the bottom surfaces of the scales so as to respectively and correspondingly limit the three scales of the lower-layer subunit adjacent to the three sides of the scales; or an integral stop block can be arranged to face and limit three scales of the lower-layer subunit adjacent to three edges of the stop block.

Preferably, the step surface is an arc surface which is matched with the curved edge of the Leluo triangular scale of the lower subunit.

The invention preferably designs the step surface to be an arc surface to be matched with the curved edge of the Leluo triangular scale of the lower subunit, so as to improve the contact area and ensure the stable structure.

More preferably, the thickness of the stop block is 1.5mm-2.5 mm.

Preferably, a magic tape is arranged on one surface of the stop block, which is far away from the Lelo triangular scale where the stop block is located, and is used for being adhered to the surface of clothes.

A scale type protective arm comprises the scale type protective layer.

Further preferably, the protective cover further comprises a magic tape and a fibrous ground ice sleeve, and the scale-type protective layer is adhered to the fibrous ground ice sleeve through the magic tape.

The armguard provided by the invention is a comfortable armguard which has a blocking function, is light and easy to wear, can meet daily on-duty wearing requirements of policemen, and can effectively improve the protection capability of the policemen.

The design case, if the armguard wholly shows that arm outside is half parcel structure, accords with the check and keeps off the habit, does benefit to the arm protection under the emergency. Meanwhile, the inner side of the guard arm is flexible and comfortable without scales. Comfortable and light wearing and strong shock resistance and buffering capacity.

The invention has the following advantages and beneficial effects:

the protective layer provided by the invention adopts two overlapped scales of the triangular lino scale, can be expanded and deformed, and has rigidity protection and comfort.

According to the protective layer provided by the invention, the Lyono triangular scales are adhered to the area to be protected through the magic tape, so that personalized requirements and replacement maintenance are facilitated, local replacement is realized, individualized differences are met, and the maintenance cost is reduced.
