Description

Technical Field

[0001] This utility model belongs to the field of helmet technology, and in particular relates to a safety buckle. Background Technology

[0002] Helmets are essential safety equipment for sports such as cycling, skateboarding, and skiing. Their safety depends not only on the strength of the shell itself but also on the effectiveness of the strap system in securing the helmet to the wearer's head during a collision. Therefore, the reliability, convenience, and efficiency of the helmet buckle directly affect the overall protective effect and user experience.

[0003] Currently, the mainstream helmet buckles on the market are mainly divided into snap-on buckles. This type of buckle is locked by a snap-on piece and a slot with an internal locking lug. To unlock, the user needs to press the release buttons on both sides of the slot with both hands at the same time, using the lever principle to disengage the locking lug and pull out the snap-on piece.

[0004] The disadvantage of this structure is that it is cumbersome to operate. In an emergency or when the helmet needs to be removed quickly, pressing with both hands at the same time will waste valuable time. At the same time, the operation is difficult for children, users with insufficient hand strength or poor dexterity, which may result in the inability to unlock or lock correctly. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art by providing a safety buckle that combines a sliding locking element with a magnetic structure, thus solving the problem of cumbersome helmet buckle operation.

[0006] The technical solution of this utility model is as follows: A safety buckle includes a male buckle, a female buckle, and a locking component. The locking component is slidably disposed on the male buckle. The male buckle is provided with a first magnetic attraction part. The locking component is provided with a sliding space for the first magnetic attraction part to move. A third magnetic attraction part is provided on the side of the sliding space to attract the first magnetic attraction part. The female buckle is provided with a second magnetic attraction part. The second magnetic attraction part extends into the sliding space and contacts and engages with the first magnetic attraction part. At least one set of locking structures is provided between the female buckle and the locking component. The locking structure includes a locking bottom surface disposed on the female buckle and a locking top surface disposed on the locking component. The locking component is provided with a release part. The release part extends beyond the end face of the male buckle away from the female buckle. After the male buckle is placed above the female buckle, the first magnetic attraction part and the second magnetic attraction part attract each other. The locking member slides as the third magnetic attraction part approaches the first magnetic attraction part. After the third magnetic attraction part abuts against the side wall of the first magnetic attraction part, the top surface of the lock is below the bottom surface of the lock.

[0007] A further feature of this invention is that the locking structure includes protruding structures that protrude towards each other in the left and right directions of the female buckle and the locking member, respectively. The bottom surface of the lock is the bottom end surface of the protruding structure on the female buckle, and the top surface of the lock is the top end surface of the protruding structure on the locking member.

[0008] A further feature of this invention is that the locking structure is provided in two sets, and the protruding structures of the locking member protrude from the end faces of both ends of the locking member along the direction of the third magnetic attraction part close to the first magnetic attraction part.

[0009] Further features of this invention: The male buckle includes a male buckle body and a male buckle end cap. The first magnetic suction part is integrally disposed on the male buckle body. A groove for placing a magnet is opened on the top of the first magnetic suction part. The male buckle end cap is integrally or detachably installed on the top of the male buckle body. The male buckle end cap covers the opening of the groove on the top of the first magnetic suction part.

[0010] A further feature of this invention is as follows: the female buckle includes a female buckle body and a female buckle end cap, the second magnetic attraction part is integrally disposed on the female buckle body, the bottom of the second magnetic attraction part is provided with a groove for placing a magnet, the female buckle end cap is integrally or detachably installed on the bottom of the female buckle body, and the female buckle end cap covers the bottom groove opening of the second magnetic attraction part.

[0011] A further improvement of this utility model: the release part includes a hook disposed on the side of the locking member and a rope attached to the hook, the top of the male buckle end cap is provided with a release opening, and the rope is attached to the hook and extends out of the release opening to the outside of the male buckle end cap.

[0012] A further feature of this invention is that an arc-shaped cover is integrally formed on the top of the male buckle end cover, and an opening is formed between the arc-shaped cover and the male buckle end cover in the direction away from the first magnetic attraction part from the third magnetic attraction part. The opening between the arc-shaped cover and the male buckle end cover is connected to the release opening.

[0013] A further feature of this invention is that the hook opening faces the female buckle, and a limiting protrusion protrudes from the side of the locking member, with the limiting protrusion located at the hook opening.

[0014] A further feature of this invention is that a release opening is formed between the top of the male buckle end cap and the female buckle body, the release part extends through the release opening to the outside of the male buckle end cap, and after the third magnetic attraction part abuts against the side wall of the first magnetic attraction part, the gap between the release part and the release opening in the sliding direction of the locking member is not less than the stroke of the locking member on the male buckle.

[0015] A further feature of this invention is that both the male and female buckles are provided with a strap buckle for wrapping the strap. The strap buckle has an anti-slip part on the inner wall of the strap. One end of the anti-slip part is integrally connected to the strap buckle, and the other end is an elastic end that extends downward and is inclined outward. A gap structure is provided between the elastic end of the anti-slip part and the side wall of the strap buckle.

[0016] The beneficial effects of this utility model are as follows: By combining the sliding locking component with the magnetic structure, the locking component is driven to slide by pulling or pushing the release part that extends out of the male buckle, so that the top surface of the lock and the bottom surface of the lock are separated, thereby realizing the unlocking of the male buckle and the female buckle. Compared with the traditional buckle that requires both hands to press simultaneously, this solution only requires one hand to pull or push to unlock, which greatly simplifies the operation process. Furthermore, when the male and female buckles approach each other, the first and second magnetic attraction parts attract each other and automatically position themselves. At the same time, the locking parts automatically slide to the locking position under the magnetic force of the third and first magnetic attraction parts. This process does not require manual alignment or forceful pressing, and the locking state is clear and highly reliable. Attached Figure Description

[0019] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] It should be noted that in the description of this utility model, all directional indicators (such as up, down, forward, backward, etc.) are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0021] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a number" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0022] like Figure 1-10 As shown, a safety buckle includes a male buckle 1 and a female buckle 2 that can be locked and separated from each other. A locking element 3 is slidably disposed on the male buckle 1. Both sides of the male buckle 1 and the female buckle 2 are provided with strap buckles 4 for wrapping around the helmet strap. The strap buckle 4 has an anti-slip part 41 on the inner wall surface where the strap is installed. One end of the anti-slip part 41 is integrally connected to the strap buckle 4, and the other end is an elastic end that extends downward and is inclined outward. A gap structure is provided between the elastic end of the anti-slip part 41 and the side wall of the strap buckle 4 for the elastic end of the anti-slip part 41 to press and accommodate. When the helmet strap is inserted downward into the strap buckle 4, the insertion direction follows the inclined setting of the anti-slip part 41, and it can be inserted smoothly. When the helmet strap is wrapped and inserted into the strap buckle 4, when the strap moves in the upward direction of pull-out, it is squeezed and restricted from pulling out by the anti-slip part 41.

[0023] The male buckle 1 includes a male buckle body 12 and a male buckle end cap 13, such as Figure 9As shown, the male buckle body 12 is integrally provided with a first magnetic suction part 11. The top of the first magnetic suction part 11 is provided with a groove for placing a magnet. The male buckle end cap 13 is integrally or detachably connected to the top of the male buckle body 12. The male buckle end cap 13 covers the top groove opening of the first magnetic suction part 11 to limit the magnet therein.

[0024] The female buckle 2 includes a female buckle body 23 and a female buckle end cap 24, such as Figure 10 As shown, the female buckle body 23 is integrally provided with a second magnetic attraction part 22. The bottom of the second magnetic attraction part 22 is provided with a groove for placing a magnet. The female buckle end cap 24 is integrally or detachably installed on the bottom of the female buckle body 23. The female buckle end cap 24 covers the bottom groove opening of the second magnetic attraction part 22 to limit the magnet therein. After the male buckle 1 is placed on the female buckle 2, the second magnetic attraction part 21 extends into the sliding space 31 and contacts and attracts the first magnetic attraction part 11, realizing the initial positioning of the male buckle 1 and the female buckle 2.

[0025] The locking member 3 is provided with a sliding space 31 for the first magnetic attraction part 11 to move. In this embodiment, the locking member 3 is a ring structure, its outer frame slides on the male buckle 1, and the inner through hole structure is the sliding space 31. The first magnetic attraction part 11 is located in the sliding space 31. The side of the sliding space 31 is provided with a third magnetic attraction part 32 that attracts the first magnetic attraction part 11. In this embodiment, the third magnetic attraction part 32 is integrally provided with the locking member 3. The top of the third magnetic attraction part 32 is provided with a groove for placing a magnet. The male buckle end cap 13 covers the top groove opening of the third magnetic attraction part 32 to limit the magnet therein.

[0026] After the male buckle 1 is placed on the female buckle 2, the locking element 3 is located between the male buckle 1 and the female buckle 2.

[0027] Two sets of locking structures are provided between the female buckle 2 and the locking member 3. The locking structure includes protrusions that protrude towards each other in the left and right directions of the female buckle 2 and the locking member 3, respectively. The protrusions of the locking member 3 protrude from the end faces of both ends of the locking member 3 along the direction of the third magnetic attraction part 32 close to the first magnetic attraction part 11. The bottom end face of the protrusions on the female buckle 2 is the bottom surface 22 of the locking, and the top end face of the protrusions on the locking member 3 is the top surface 34 of the locking. After the male buckle 1 is placed above the female buckle 2, the first magnetic attraction part 11 and the second magnetic attraction part 21 are attracted to each other. The locking member 3 slides as the third magnetic attraction part 32 approaches the first magnetic attraction part 11. After the third magnetic attraction part 32 abuts against the side wall of the first magnetic attraction part 11, the top surface 34 of the locking member is below the bottom surface 22 of the locking member, realizing mechanical self-locking. Thus, after the first magnetic attraction part 11 and the second magnetic attraction part 21 are separated by external force, the top surface 34 of the locking member contacts and interferes with the top surface 22 of the locking member. The magnetic attraction force is responsible for the main binding force, while the mechanical locking structure provides a second layer of security, forming a dual guarantee of magnetic force and mechanical interlocking, which is more secure.

[0028] In this solution, the locking member 3 is also provided with a release part 33, which extends to the end face of the male buckle 1 away from the female buckle 2; the specific implementation of the release part 33 is as follows in Embodiment 1 and Embodiment 2. Example 1

[0029] like Figure 1-3 As shown, a release opening 131 is formed between the top of the male buckle end cap 13 and the female buckle body 23. The release part 33 extends through the release opening 131 to the outside of the male buckle end cap 13. After the third magnetic attraction part 32 abuts against the side wall of the first magnetic attraction part 11, the gap between the release part 33 and the release opening 131 in the sliding direction of the locking member 3 is not less than the stroke of the locking member 3 on the male buckle 1, ensuring that there is enough space to complete the unlocking when the release part is pulled, and avoiding the "jamming" phenomenon caused by insufficient stroke.

[0030] like Figure 4 As shown, the specific structure of the release part 33 extending to the outside of the male end cap 13 is not limited, and it can extend above the release opening 131. Example 2

[0031] like Figure 5-8 As shown, the release part 33 includes a hook 35 disposed on the side of the locking member 3 and a rope attached to the hook 35. The top of the male buckle end cap 13 is provided with a release opening 131. After the rope is attached to the hook 35, it extends out of the release opening 131 to the outside of the male buckle end cap 13. Figure 5 As shown in the image.

[0032] In this embodiment, an arc-shaped cover 132 is integrally provided on the top of the male buckle end cap 13. An opening is formed between the arc-shaped cover 132 and the male buckle end cap 13 in the direction away from the first magnetic attraction part 11 and the direction of the third magnetic attraction part 32. The opening between the arc-shaped cover 132 and the male buckle end cap 13 is connected to the release opening 131. After the rope passes through the release opening 131, it extends out of the opening between the arc-shaped cover 132 and the male buckle end cap 13, so that the rope is placed outside the male buckle end cap 13, which makes it convenient for the user to quickly find and operate.

[0033] In this embodiment, the opening of the hook 35 faces the direction of the female buckle 2, and the side of the locking member 3 has a limiting protrusion 36, which is located at the opening of the hook 35. The limiting protrusion 36 reduces the size of the opening of the hook 35 or directly forms a closed loop structure, so that the rope can be released from the hook 35 by external force after being tied to the hook 35.

[0034] Specifically, this solution combines a sliding locking element 3 with a magnetic structure. By pulling or pushing, the release part 33 extending outside the male buckle 1 is driven to slide the locking element 3, causing the top surface 34 of the buckle to separate from the bottom surface 22 of the buckle, thereby unlocking the male buckle 1 and the female buckle 2. Compared with traditional buckles that require both hands to press simultaneously, this solution only requires one hand to pull or push to unlock, greatly simplifying the operation process. Furthermore, when the male buckle 1 and the female buckle 2 are close together, the first magnetic part and the second magnetic part attract each other and automatically position themselves. At the same time, the locking element 3 automatically slides to the locking position under the magnetic force of the third magnetic part and the first magnetic part. This process does not require manual alignment or forceful pressing, and the locking state is clear and highly reliable.

[0035] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
