Utility model content

The purpose of this utility model is, a kind of shellproof chip is provided, solve the not science fixed form of shellproof chip in traditional flak jackets processing and fabricating, the utility model is fixed by carrying out special sewing to flak jackets chip, well can not only avoid the slippage between shellproof chip layer, and by the flak jackets that this kind of sewing fixed form is processed, bullet-proof can also be greatly improved.

A kind of shellproof chip, comprises multilayer flak jackets chip and is superimposed; Described every layer of flak jackets chip all equal and opposite in directions, shape is identical;

What the left and right sides, the top point of described every layer of flak jackets chip was all fixed links together;

Illustrate as one, the mode that the left and right sides, described top point is sewed by sewing machine is fixedly connected with, and connecting line length is 3CM;

What the both wings of described every layer of flak jackets chip were all fixed links together;

Illustrate as one, the mode that described both wings are sewed by sewing machine is fixedly connected with, and connecting line length is the sub-fraction that the oblique side of sub-fraction and top that the whole of both wings and bottom are connected with both wings is connected with both wings, and concrete ratio can refer to shown in Fig. 2;

Illustrate as one, the connecting line of the left and right sides, described top point, both wings coupling part is that symmetrical formula is arranged;

A sewing fixed form for shellproof chip, the technical scheme that the utility model provides comprises following implementation step:

Step one: the flak jackets chip of the suitable number of plies cut is superimposed, is fixed by fixing;

Step 2: previously prepared good sewing fixed line template is positioned on the shellproof chip cut, rules according to template circuit with pencil;

The size of described sewing fixed line template is made with reference to the size of different size flak jackets, identical with the built-in shellproof die size of described flak jackets, shape, and has pre-designed above it, and the template circuit of up/down perforation;

Illustrate as one, described template circuit is symmetrical set;

Described template circuit is divided into upper and lower two parts, and described upper part circuit is fixedly installed according to both sides, the top point of flak jackets chip, and fixing line length is 3cm;

Described lower part is carried out point along both wings and is fixed, and apart from edge 2cm, fixing line length is with reference to shown in Fig. 2 ratio;

Step 3: carry out sewing with sewing device by the circuit that pencil is finished and fix;

Illustrate as one, described sewing threads can be one in polyester thread, nylon wire or aramid line or combination;

Step 4: remove described fixing, completes the sewing steady job of shellproof chip, proceeds other assembly processes of flak jackets.

The beneficial effects of the utility model:

1, the utility model adopts special sewing fixed structure, flak jackets chip is obtained and more effectively fixes, avoid the slippage between shellproof chip layer, and by this kind of sewing fixed structure, the ballistic performance of flak jackets chip can be made to get a promotion;

2, the utility model can make ballistic performance get a promotion, mainly refer to the destruction effectively reducing backing cup depth and human body is brought, namely shellproof chip is while prevention bullet runs, draw texture can be produced, thus make the back lining materials being close to the anthropomorphic body of chip dies produce depressed deformation, the size of cup depth has reacted the quality of ballistic performance, the flak jackets that the special sewing fixed structure of the utility model can be produced than existing sewing fixed form, when being hit by a bullet, has less backing cup depth.

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.

With reference to shown in Fig. 1, a kind of shellproof chip, comprises multilayer flak jackets chip and is superimposed; Described every layer of flak jackets chip all equal and opposite in directions, shape is identical;

With reference to shown in Fig. 3, a kind of sewing fixed form of shellproof chip, this technical scheme comprises following implementation step:

Illustrate as one, described template circuit is symmetrical set;

In order to better the beneficial effects of the utility model are described, now contrast by experiment, providing following embodiment and comparative example:

Embodiment 1:

Cut 28 layers of shellproof chip PF220 (220g/m2) are superimposed, and fix by fixing, fixed line of sewing template (with reference to shown in Fig. 2) is positioned on 28 layers of shellproof chip, rule with the circuit of pencil by fixed form, carry out sewing with sewing machine by circuit to fix, sewing technology is flush joint, and sewing line length is with reference to the step 2 in the utility model fixed form; Then, sewing is fixed flak jackets chip by the ballistic performance of the shellproof chip of standard testing of IIIA level 9mm bullet in NIJ0101.04 standard;

Experimental result: six bullets are all guarded against, first three rifle cup depth is respectively 21.3,22.4,19.8, average depression depth: 21.2;

Comparative example 1:(does not sew fixing)

Specifically implement with reference to identical bullet resistant material in embodiment 1,28 layers that are about to cut shellproof chip PF220 (220g/m2) are superimposed, do not carry out sewing to fix, directly test the ballistic performance of shellproof chip by IIIA level 9mm bullet in NIJ0101.04 standard;

Experimental result: six bullets are all guarded against, first three rifle cup depth is respectively 28.7,27.9,28.1, average depression depth: 28.2, and depression value is greater than the utility model embodiment 1, and under namely same bullet resistant material, bulletproof effect embodiment 1 is winning;

Comparative example 2:(is by the sewing fixed form of prior art)

Specifically implement by the concrete operation step of embodiment and identical bullet resistant material, difference is to adopt the fixed form of conventional sewing fixed line (Fig. 1), sewing is fixed flak jackets chip test the ballistic performance of shellproof chip by IIIA level 9mm bullet in NIJ0101.04 standard;

Experimental result: six bullets are all guarded against, first three rifle cup depth is respectively 27.5,28.7,27.6, average depression depth: 27.9, under namely same bullet resistant material, bulletproof effect after adopting prior art sewing fixing is better than comparative example 1, is inferior to the utility model embodiment 1;

The utility model adopts special sewing fixed structure, flak jackets chip is obtained more effectively fix, avoid the slippage between shellproof chip layer, and by this kind of sewing fixed structure mode, the ballistic performance of flak jackets chip can be made greatly to be promoted; The utility model can make ballistic performance get a promotion, mainly refer to the destruction effectively reducing backing cup depth and human body is brought, namely shellproof chip is while prevention bullet runs, draw texture can be produced, thus make the back lining materials being close to the anthropomorphic body of chip dies produce depressed deformation, the size of cup depth has reacted the quality of ballistic performance, the flak jackets that the special sewing fixed structure of the utility model can be produced than existing sewing fixed form, when being hit by a bullet, has less backing cup depth.

Above-describedly be only preferred embodiment of the present utility model; be understood that; the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping; and be not used in restriction protection domain of the present utility model; all any amendments, equivalent replacement etc. made within thought of the present utility model and principle, all should be included within protection domain of the present utility model.
