Description

Hollow hemispherical stab-proof body structure with card slots

【Technical Field】

The invention belongs to the technical field of stab-resistant protective bodies, and particularly relates to a hollow hemispherical stab-resistant protective body structure with a slot.

【Background technique】

At present, the domestic security situation is very severe. Various violent criminal cases occur from time to time. In order to maintain public order, police officers, anti-riot personnel, and economic security personnel have limited weight-bearing capacity of law enforcement personnel. Police stab-resistant clothing is essential protective equipment. Its comfort and safety have always been the research hotspots of stab-resistant body suits.

For comfort, its flexibility and weight are the key considerations in the design of the stab-resistant protective body structure. In the prior art, the patent No. 2016100554406 discloses a bionic stab-resistant chip and stab-resistant equipment, which adopts a hollow hemispherical structure Although the weight can be greatly reduced and the comfort is improved, in terms of safety performance, if the stab-resistant chip of this structure is used to make cloth, due to the characteristics of the hemispherical structure, when the blade is bayonet on the peripheral sphere of the stab-resistant chip Except for the vertical stabbing at the center of the surrounding sphere, any other stabbing points will guide the blade to the gap between the two anti-stab chips, which will greatly increase the probability of the gap being stabbed. It is possible that the blade will slide into the gap. At this time, the base cloth plays a protective role against the blade. It is conceivable that its safety factor is greatly reduced. Therefore, it is necessary to provide a new card slot The hollow hemispherical anti-stab protection structure solves the above problems.

[Content of the invention]

The main purpose of the present invention is to provide a hollow hemispherical stab-proof body structure with a card slot, which can not only achieve lighter weight and improve comfort, but also ensure higher safety performance.

The present invention achieves the above-mentioned object through the following technical solutions: a hollow hemispherical stab-resistant body structure with a card slot, which includes a base cloth, a number of stab-resistant units arranged on the base cloth, and the stab-resistant unit It is a semi-spherical or semi-ellipsoidal structure with a hollow interior, and the spheroid surface of the stab-proof unit is provided with a plurality of clamping grooves from top to bottom to guide the blade to the clamping groove.

Further, the locking groove is an independent ring structure, or a spiral ring structure, or an independent groove irregularly distributed on the surface of the stab-resistant unit sphere.

Further, the cross-sectional shape of the clamping groove is a V-shaped structure, and the cutting edge is guided inward to realize the blocking and blocking function of the cutting edge.

Further, it also includes a gap stab prevention sheet filling the gaps between the stab prevention units.

Further, the gap stab prevention sheet and the stab prevention unit are arranged seamlessly, and a V-shaped groove is formed on the opposite surface.

Further, the stab-proof units are arranged in a staggered arrangement, and every three of the stab-proof units surrounds a gap area, and the gap stab-proof sheet fills the gap area.

Further, a gap area is formed around every four of the stab prevention units, and the gap stab prevention sheet fills the gap area.

Compared with the prior art, the beneficial effects of the hollow hemispherical stab-proof body structure with a card slot of the present invention are:

1) By setting the anti-stab unit with a hollow hemispherical structure, it has the main anti-stab function to the outside world, and through the hollow design, on the one hand, the overall weight is greatly reduced and the comfort is improved; on the other hand, the hemisphere is adopted The body arch structure greatly improves the impact resistance, with higher strength and impact resistance;

2) By setting a number of slots on the surface of the hollow hemisphere anti-stab unit, the slot is used to guide the cutting edge of the anti-stab unit into the slot, effectively avoiding the knife edge being guided to the bottom of the anti-stab unit and stabbing the base fabric The risk occurs, greatly improving the safety performance;

3) By designing the gap stab-proof sheet, the safety risk caused by inserting the blade into the gap is effectively avoided, and the gap stab-proof sheet is used to undertake the stab-proof function at the gap.

【detailed description】

Examples:

1, this embodiment is a hollow hemispherical stab-resistant protective body structure 100 with a card slot, which includes a base fabric 1, a plurality of stab-resistant units 2 arranged on the base fabric 1, and the stab-resistant unit 2 is inside With a hollow hemispherical or semi-ellipsoidal structure, the spheroid surface of the anti-stab unit 2 is provided with a plurality of grooves from top to bottom to guide the blade to the clamping groove 21 for clamping.

Please refer to FIG. 3, the clamping groove 21 may adopt an independent ring structure or a spiral ring structure, or an independent groove irregularly distributed on the surface of the spheroid of the anti-stab unit 2. The cross-sectional shape of the clamping groove 21 is a V-shaped structure and guides the cutting edge inward to realize the blocking function of the cutting edge.

4, this embodiment also includes a gap stab prevention sheet 3 filled in the gaps between the stab prevention units 2. The gap stab prevention sheet 3 and the stab prevention unit 2 are arranged seamlessly and a V-shaped groove 31 is formed on the opposite surface .

In an embodiment, the stab-proof units 2 are arranged in a staggered arrangement, and every three stab-proof units 2 are surrounded to form a gap area, so that the gap area is as small as possible and the safety factor is improved. In addition, the gap stab-proof sheet 3 fills the gap area, which further strengthens the stab-resistant capability of the gap area and improves the safety performance. In another embodiment, referring to FIG. 2, every four anti-stab units 2 surround a gap area, and the gap anti-stab sheet 3 fills up the gap area, which strengthens the anti-stab ability of the gap area and improves safety performance.

This solution is provided with a hollow hemispherical anti-stab unit, which has the main anti-stab function to the outside world, and through the hollow design, on the one hand, the overall weight is greatly reduced and the comfort is improved; on the other hand, the hemisphere is adopted The arched structure of the body greatly improves the impact resistance and has high strength and impact resistance; by setting a number of slots on the surface of the hollow hemisphere stab-resistant unit, the slot is used to guide the blade of the stab-resistant unit The card slot effectively avoids the risk of the blade being guided to the bottom of the stab-resistant unit and piercing the base fabric, which greatly improves the safety performance; by designing the stab-resistant bottom plate, the security risk caused by the blade inserting into the gap is effectively avoided. The slit anti-stab sheet is used to undertake the anti-stab function at the slit.
