Disclosure of Invention

The utility model aims at having the above-mentioned problem to current technique, provided a collapsible helmet, the utility model provides a technical problem how make folding that the helmet can be better.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides a collapsible helmet, includes a plurality of layers of telescopic casings, and the top of a plurality of layers of casings is all seted up except that the top layer casing and is placed the mouth, the external diameter of casing is less than the one deck down the diameter of placing the mouth of casing, its characterized in that, it is adjacent be equipped with connection structure, limit structure between the casing and can prevent the waterproof construction who leaks between the casing, adjacent through connection structure interconnect between the casing, adjacent every layer fix on the mouth of placing of corresponding casing through limit structure between the casing.

The connecting structure can connect the shell bodies of all layers, so that the helmet is prevented from being disassembled, and the firmness of the helmet is enhanced; the limiting structure can limit the movement of the shells of the adjacent layers after the shells of the adjacent layers stretch in place, so that the firmness of the helmet is enhanced; the waterproof structure can prevent rainwater from entering the helmet from the space between adjacent layers of shells, so that the sealing performance of the helmet is enhanced; simultaneously, opening spacing back, pressing down the helmet from the top and can realizing folding, because connection structure's connection, also can not disintegrate this moment between every layer of casing to the realization is to better folding of helmet.

In the foldable helmet, the connecting structure comprises a plurality of groups of fixing pieces and a plurality of elastic pieces fixed between the adjacent fixing pieces, the plurality of groups of fixing pieces are respectively fixed on the inner walls of the plurality of layers of shells, and the plurality of elastic pieces can bend along with the movement of the shells corresponding to the fixing pieces. Every layer of casing carries out interconnect through the mounting connection elastic component of fixing on respective inner wall, because the distance between every layer of casing and the adjacent layer casing is different, and the elastic component can realize crooked when folding, can stretch again after targetting in place to the realization carries out better folding to the helmet.

In foretell collapsible helmet, a plurality of the elastic component is the polypropylene plastic strip, every group the mounting all includes four fixed knots that the circumference distributes on shells inner wall, four fixed knot all arranges with the fixed knot collineation that corresponds on other layer casings, every the fixed part has all been seted up at the both ends of polypropylene plastic strip, and a plurality of polypropylene plastic strips are fixed respectively through the fixed part between the fixed knot on adjacent casing. Above-mentioned structure can make the atress even between every layer of casing, prevents that single polypropylene plastic strip from atress alone from leading to the life shortens, fixed polypropylene plastic strip that can also be better, also makes every layer of casing become a whole simultaneously.

In foretell collapsible helmet, waterproof construction is including setting up the waterproof groove in the casing bottom except that bottom shell and setting up the barb portion at the adjacent layer casing top except that top layer casing, the bottom border of casing is rolled over outwards and is formed above-mentioned waterproof groove, the top of casing is rolled over inwards and is formed above-mentioned barb portion, barb portion's both sides face cover is equipped with the sealing washer, barb portion passes through in the sealing washer embedding waterproof groove. The waterproof groove can limit the moving position between every layer of shell on the one hand, and on the other hand can also cooperate the sealing washer to prevent that rainwater from entering into the helmet from the gap between the adjacent layer of shell.

In the above foldable helmet, the limiting structure includes a bolt, a plurality of first limiting parts arranged at the bottom of the inner wall of the shell, and a second limiting part arranged at the top of the inner wall of the shell of the adjacent layer and corresponding to the first limiting parts, bolt holes are formed in the first limiting parts and the second limiting parts, and the bolt can penetrate between the first limiting parts and the second limiting parts through the bolt holes. The first limiting block and the second limiting block can be matched with the bolt to prevent the bolt from retracting into the shells of adjacent layers after each layer of shell extends in place, and relative fixation between the first limiting part and the second limiting part can be kept, so that firmness of the helmet can be better enhanced.

In the foldable helmet, one side of the second limiting part, which is close to the inner wall of the shell, is provided with a butting part, the inner end of the bolt is butted against the butting part after being inserted into the bolt hole, the first limiting part is arranged at a position, which is positioned below the waterproof groove, on the inner wall of the shell, a convex shielding part of the first limiting part is arranged above the first limiting part, and the shielding part in each layer of the shell is arranged in a collinear way with the shielding part corresponding to the shell of the adjacent layer. The abutting part can abut against one end of the bolt after the bolt is inserted in place, so that the bolt is prevented from being inserted into the bolt hole too deeply and being incapable of resetting; the shielding part can be projected relative to the bolt and preferentially abutted against the head when the helmet is worn on the head, so that the head is prevented from being touched by the bolt.

In the foldable helmet, the first limiting parts are four in one group and are respectively and horizontally distributed at the bottom of each layer of shell in a circumferential mode, the second limiting parts are four in one group and are respectively and horizontally distributed on the inner wall of each layer of shell in a circumferential mode, and the first limiting parts and the second limiting parts are arranged in a collinear mode. The structure can enable the first limiting block and the second limiting block to freely control the folding of each layer of shell, and can better strengthen the firmness of the helmet.

In foretell collapsible helmet, the inner periphery side of bottom shell is equipped with the cushion ring, the cushion ring is including the portion of bursting and the laminating portion of contracting, the portion of bursting that contracts sets up for bottom shell leanin, the portion of bursting and laminating portion have the contained angle. When the bottom shell is impacted by the outside, the crumple part can absorb impact energy and can be destroyed by itself, the joint part can increase the contact area with the head, and the impact force in the unit area of the head is reduced.

In the above foldable helmet, the lower side surface of the top shell is provided with a buffer pad, and the outer diameter of the buffer pad is smaller than the inner diameter of the buffer ring. The structure can better enable the helmet to be folded.

In the foldable helmet, two ends of the wind-blocking sheet are fixed on two sides of the shell positioned at the bottommost layer, the height of the middle part of the wind-blocking sheet is equal to that of the shell positioned at the bottom layer, and the height of the middle part of the wind-blocking sheet is gradually reduced towards the two ends. The wind-shield sheet has the same height as the helmet after the helmet is folded, and does not occupy more space.

Compared with the prior art, the foldable helmet has the advantages of better folding of the helmet and firmness enhancement of the helmet.
