[ invention ]

The invention mainly aims to provide a hollow hemispherical stab-resistant protective body structure with a clamping groove, which can realize light weight, improve comfort and ensure higher safety performance.

The invention realizes the aim through the following technical scheme: the utility model provides a thorn protection body structure is prevented to cavity hemisphere style with draw-in groove, its includes the base cloth, arranges and set up a plurality of thorn units that prevent on the base cloth, prevent thorn unit is inside hollow hemisphere or semi-ellipsoidal structure, the spheroid surface top-down of preventing thorn unit is provided with the draw-in groove that a plurality of draw-in grooves guide blade blocked.

Further, the clamping grooves are of independent annular structures, spiral annular structures or independent grooves irregularly distributed on the surface of the anti-puncture unit sphere.

Further, the cross section shape of the clamping groove is of a V-shaped structure, and the cutting edge is guided inwards to realize the clamping and stopping functions of the cutting edge.

Further, the anti-pricking device also comprises a gap anti-pricking sheet filled in the gap between the anti-pricking units.

Further, the slit anti-puncturing sheet and the anti-puncturing unit are arranged in a slit-free manner, and a V-shaped groove is formed in the opposite surface.

Furthermore, the anti-puncturing units are arranged in a staggered manner, each three anti-puncturing units surrounds a gap area, and the gap area is filled with the gap anti-puncturing sheets.

Further, a gap area is formed around each four anti-puncturing units, and the gap area is filled with the gap anti-puncturing sheets.

Compared with the prior art, the hollow hemispherical stab-resistant protective body structure with the clamping groove has the beneficial effects that:

1) The anti-prick unit with the hollow hemispherical structure plays a main anti-prick function to the outside, and through the hollow design, on one hand, the overall weight is greatly reduced, and the comfort level is improved; on the other hand, the hemispherical arch structure is adopted, so that the anti-collision capacity is greatly improved, and the impact-resistant steel has higher strength and anti-collision capacity;

2) The clamping grooves are formed in the surfaces of the hollow hemispheroidal stab-preventing units, and the cutting edges of the stab-preventing units are guided into the clamping grooves by the clamping grooves, so that the risk that the cutting edges are guided to the base fabrics in the bottom stabs of the stab-preventing units is effectively avoided, and the safety performance is greatly improved;

3) Through the design gap anti-thorn piece, effectually avoided the cutting edge to insert the gap and produced the security risk, utilized the gap to prevent thorn piece to bear the thorn function of gap department.

[ detailed description ] of the invention

Examples:

referring to fig. 1, the present embodiment is a hollow hemispherical anti-piercing protection structure 100 with a clamping groove, which includes a base cloth 1, a plurality of anti-piercing units 2 arranged on the base cloth 1, wherein the anti-piercing units 2 are hollow hemispheroids or semi-ellipsoids, and a plurality of clamping grooves are formed on the sphere surface of the anti-piercing units 2 from top to bottom to guide the cutting edges to the clamping grooves 21.

Referring to fig. 3, the clamping groove 21 may be an independent annular structure, a spiral annular structure, or an irregular independent groove distributed on the surface of the sphere of the anti-piercing unit 2. The cross section of the clamping groove 21 is of a V-shaped structure and guides the blade inwards to realize the clamping and stopping functions of the blade.

Referring to fig. 4, the present embodiment further includes a slit anti-penetration sheet 3 filled in the slit between the anti-penetration units 2, the slit anti-penetration sheet 3 and the anti-penetration units 2 are disposed in a slit manner and V-shaped grooves 31 are formed on opposite surfaces.

In an embodiment, the stab-preventing units 2 are arranged in a staggered manner, and each three stab-preventing units 2 form a gap area in a surrounding manner, so that the gap area is as small as possible, and the safety factor is improved. In addition, the gap anti-puncture sheet 3 fills the gap area, so that the anti-puncture capability of the gap area is further enhanced, and the safety performance is improved. In another embodiment, referring to fig. 2, each four stab-resistant units 2 surrounds a slit area, the slit area is filled with the slit stab-resistant sheet 3, so that the stab-resistant capability of the slit area is enhanced, and the safety performance is improved.

According to the scheme, the thorn-proof unit with the hollow hemispherical structure plays a main thorn-proof function to the outside, and due to the hollow design, on one hand, the overall weight is greatly reduced, and the comfort level is improved; on the other hand, the hemispherical arch structure is adopted, so that the anti-collision capacity is greatly improved, and the impact-resistant steel has higher strength and anti-collision capacity; the clamping grooves are formed in the surfaces of the hollow hemispheroidal stab-preventing units, and the cutting edges of the stab-preventing units are guided into the clamping grooves by the clamping grooves, so that the risk that the cutting edges are guided to the base fabrics in the bottom stabs of the stab-preventing units is effectively avoided, and the safety performance is greatly improved; through the design of the stab-resistant bottom plate, the safety risk caused by the fact that the cutting edge is inserted into the gap is effectively avoided, and the stab-resistant function of the gap is borne by the gap stab-resistant sheet.

What has been described above is merely some embodiments of the present invention. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the invention.
