[0002] A safety helmet is a personal protective equipment used to protect the head from injuries caused by impacts, flying objects, falling objects, etc. It is widely used in construction sites, factories, mines, laboratories, and other situations requiring head protection.

[0003] Currently, the disassembly process of various straps inside safety helmets, such as the neck strap and chin strap, is not ideal, making it cumbersome to replace them. It requires reaching deep into the helmet cavity to operate, which is inconvenient. Summary of the Invention

[0004] The purpose of this invention is to address the problem of cumbersome replacement process for the neck strap and chin strap in existing safety helmets, and to propose a safety helmet that is easy to assemble and disassemble.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A safety helmet that is easy to assemble and disassemble is characterized in that it includes a helmet body with wearing cavities. Two pairs of front buckles, two pairs of middle buckles, and two pairs of rear buckles are symmetrically arranged in the wearing cavities on both sides of the bottom edge of the helmet body. The front buckles include a front buckle body, and a front extension piece is provided on the upper side of the front buckle body. A first perforation is opened on the front buckle body, and two sets of parallel second perforations are opened on the front extension piece. The first perforation is used to insert and connect the intertwined neck strap, and the second perforation is used to insert and connect the chin strap.

[0010] In the aforementioned easy-to-assemble and disassemble safety helmet, the central buckle includes a central buckle body, on which a third through hole is provided for inserting and connecting the intertwined neck strap.

[0011] In the aforementioned easy-to-assemble and disassemble safety helmet, two sets of center clips are provided on both sides of the bottom end of the center clip body. The outer ends of the center clips form center hook fasteners. After the two sets of center hook fasteners are inserted into two pairs of center holes, the center clip body is fixed on the helmet body.

[0012] In the aforementioned easy-to-assemble and disassemble safety helmet, the first perforation, the second perforation, and the third perforation are all straight groove holes.

[0013] In the aforementioned easy-to-assemble and disassemble safety helmet, the front extension piece is integrally formed with the front card body.

[0014] In the aforementioned easy-to-assemble and disassemble safety helmet, the bottom edge of the helmet body is provided with continuous reinforcing ribs.

[0015] In the aforementioned type of helmet that is easy to assemble and disassemble, the middle buckle on the same side is located between the front buckle and the rear buckle.

[0016] Compared with existing technologies, the disassembly and assembly of this safety helmet features a gradually changing form for each buckle, making it practical and convenient during the assembly and disassembly process. The front and rear buckles can be manufactured by mirroring each other in a mold, making the design simple. Attached Figure Description

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figure 1 and Figure 3As shown, this easy-to-assemble safety helmet includes a helmet body 1 with wearing chambers. Two pairs of front buckles 2, two pairs of middle buckles 3, and two pairs of rear buckles 4 are symmetrically arranged in the wearing chambers on both sides of the bottom edge of the helmet body. The front buckles include a front buckle body 5, and a front extension piece 6 is provided on the upper side of the front buckle body. A first through hole 7 is provided on the front buckle body, and two sets of parallel second through holes 8 are provided on the front extension piece. The first through hole is used to insert and connect the intertwined neck strap, and the second through hole is used to insert and connect the chin strap.

[0024] This product features front, middle, and rear buckles at the points inside the cap where the neck strap and chin strap connect. These buckles are used to install the neck strap and chin strap, and they are detachable from the cap body. Therefore, when it is necessary to remove the neck strap or chin strap, the corresponding buckle can be removed first, and then the neck strap or chin strap can be removed. This provides a variety of removal and replacement methods and makes the operation easier.

[0025] Furthermore, because the first and second perforations are located in different positions, the neck strap and chin strap do not easily come into contact with each other and cause interference.

[0026] like Figure 2 As shown, the bottom edge of the cap body is symmetrically provided with two sets of front pairs, middle pairs, and rear pairs of holes for connecting the front buckle, middle buckle, and rear buckle. The front pairs of holes include two pairs of front holes 9, the middle pairs of holes include two pairs of middle holes 10, and the rear pairs of holes include two pairs of rear holes 11.

[0027] Two sets of front card strips 15 are provided on both sides of the bottom of the front card body. The outer ends of the front card strips form front hook fasteners 16. After the two sets of front hook fasteners are inserted into the two pairs of front holes, the front card body is fixed on the cap body.

[0028] The front and rear fasteners are symmetrical in shape, and the rear fastener is formed by mirroring the front fastener. The front and rear holes are symmetrical.

[0029] The front and rear buckles are mirror images of each other, which simplifies the difficulty of mold development and design, and ensures the balance of structural strength inside the cap, and the neck strap is also wrapped more evenly.

[0030] like Figure 1 and Figure 4 As shown, the middle buckle includes a middle buckle body 12, and a third through hole 13 is provided on the buckle body. The third through hole is used to insert and connect the intertwined neck strap.

[0031] Two sets of middle card strips 17 are provided on both sides of the bottom end of the middle card body. The outer ends of the middle card strips form middle hook fasteners 18. After the two sets of middle hook fasteners are inserted into the two pairs of middle holes, the middle card body is fixed on the cap body.

[0032] The first, second, and third perforations are all straight slot holes.

[0033] Because the neck strap and chin strap are both strip-shaped, to avoid wrinkles caused by them passing through various perforations, all perforations are designed as straight slots, and the width of the straight slots is greater than the width of the neck strap and chin strap, so that they will not cause wrinkles due to compression.

[0034] The front extension piece is integrally molded with the front card body.

[0035] The bottom edge of the cap is provided with continuous reinforcing ribs 14.

[0036] The middle fastener on the same side is located between the front fastener and the rear fastener.

[0037] It should be understood that in the claims and description of this utility model, all instances of "comprising..." should be understood as having an open meaning, that is, their meaning is equivalent to "containing at least...", and should not be understood as having a closed meaning, that is, their meaning should not be understood as "containing only...".

[0038] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
