[0002] Currently, there are various types and styles of buckles on the market. Their function is to fasten backpack straps that pass through the buckle, thereby adjusting the length of the backpack straps to meet the needs of people of different heights. Buckles typically consist of a male buckle and a female buckle, with one end secured by webbing and the other end adjustable via webbing, allowing the selection of webbing length according to different needs.

[0003] For example, Chinese utility model CN202421176165.X discloses a novel, easy-to-press buckle, which includes a male buckle and a female buckle. The male buckle includes elastic prongs and a limiting block. Each of the two elastic prongs includes a guide end, a pressing part, and an elastic part. The guide end is the free end of the elastic prong away from the main body of the male buckle. The female buckle includes an insertion port, a guide groove, a pressing port, and a guide strip. Compared with the prior art, this utility model increases the contact surface of the buckle by setting the pressing part, allowing users to easily press the buckle to unlock even when wearing gloves. Furthermore, by setting the pressing port to communicate with the insertion port, the pressing part is fully exposed for pressing, greatly facilitating the user's pressing and unlocking of the buckle. The buckle is locked by setting the guide strip and the limiting block to be staggered, and the direct-pull locking ensures that the buckle can withstand higher tensile forces, making it suitable for protective gear such as helmets.

[0004] However, in outdoor sports, users often need to carry a lot of equipment, such as water bottles, umbrellas, flashlights, lanterns, whistles, etc. Due to the limited functionality of traditional buckles, they cannot provide much help to users. Summary of the Invention

[0005] In view of this, the present invention provides an outdoor wing clip with a whistle to solve the above-mentioned technical problems.

[0006] An outdoor wing clip with a whistle includes a male clip and a female clip for inserting the male clip.

The latch is an opening provided on one side of the slot, located on the side of the slot away from the elastic pin, and communicates with the inside of the slot. The opening at the connection between the latch and the slot occupies less than 1 / 4 of the circumference of the circular groove of the slot. The gap of the latch at the end away from the slot is smaller than the gap at the connection with the slot.

[0007] Furthermore, the male buckle also includes a guide tongue disposed between the two elastic prongs, and a strap connection buckle disposed between the elastic prongs and the whistle.

[0008] Furthermore, the two elastic pins are arranged symmetrically about the guide tongue, and each includes a guide portion, a pressing portion connecting the guide portion and the male buckle body, an elastic portion connecting the guide portion and the guide tongue, and four limiting protrusions disposed on the guide portion.

[0009] Furthermore, the guide portion is located at the end away from the male buckle body and is connected through the pressing portion. The guide portion extends in a direction away from the whistle and has an arc-shaped chamfer at its end. The pressing portion connects the guide portion and the male buckle body and provides elastic force when the elastic pin deforms. The thickness of the pressing portion is greater than the thickness of the guide portion. The elastic portion is located between the guide portion and the guide tongue and is a curved spring piece. The limiting protrusion is provided at the end of the free end of the elastic pin and is provided on the upper and lower surfaces perpendicular to the extension direction of the free end of the elastic pin, and is located on the side close to the guide tongue.

[0010] Furthermore, the guide tongue is a guide structure disposed on the axis of symmetry of the two elastic pins, extending in the same direction as the extension direction of the elastic pins, and the edges of the guide tongue are provided with arc-shaped chamfers.

[0011] Furthermore, the female buckle also includes a guide groove disposed in the insertion port, two pressing ports disposed on both sides of the guide groove, and four guide strips respectively disposed at the pressing ports.

[0012] Furthermore, the pressing port is located on both sides of the female buckle perpendicular to the direction of the insertion port opening, and the whole has an inwardly concave arc structure, and the pressing port communicates with the insertion port.

[0013] Furthermore, the guide strip is disposed on the inner wall of the female buckle along the arc of the pressing opening.

[0014] Furthermore, the slot body is circular, and the extension direction of the slot body is perpendicular to the extension direction of the elastic pin.

[0015] Furthermore, the extension direction of the slot body is inclined to the extension direction of the elastic pin.

[0016] Compared with existing technologies, the outdoor wing clip buckle with whistle provided by this utility model not only prevents the whistle from being accidentally lost during outdoor activities by setting the whistle on the male buckle, but also allows users to quickly access it in emergencies without having to search through pockets or backpacks.

[0022] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0023] like Figures 1 to 5 The diagram shows the structure of the outdoor wing clip with a whistle provided by this utility model. The outdoor wing clip with a whistle includes a male clip 10 and a female clip 20 for inserting the male clip 10. It is conceivable that the outdoor wing clip with a whistle also includes other functional modules such as a foolproof structure for inserting the male clip into the female clip, a ring structure for engaging the butterfly clip, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0024] The male buckle 10 is made of plastic injection molding and is integrally formed. It includes a male buckle body 11, a pair of elastic pins 12 disposed on the male buckle body 11, a guide tongue 13 disposed between the two elastic pins 12, a whistle 14 disposed on the male buckle body 11, and a strap connecting buckle 15 disposed between the elastic pins 12 and the whistle 14.

[0025] The male buckle body 11 is the main structure of the male buckle 10, serving as a support and connector. In practical use, a groove can be made on the back of the male buckle body 11 to save material while meeting structural strength requirements.

[0026] The two elastic pins 12 are arranged symmetrically about the guide tongue 13, and each includes a guide portion 121, a pressing portion 122 connecting the guide portion 121 and the male buckle body 11, an elastic portion 123 connecting the guide portion 121 and the guide tongue 13, and four limiting protrusions 124 provided on the guide portion 121.

[0027] The guide portion 121 is located at the end away from the male buckle body 11 and is connected by the pressing portion 122 to form an elastic deformation structure. When the male buckle 10 is inserted into the female buckle 20, the two elastic prongs 12 deform relative to each other, the two guide portions 121 move closer to each other, and spring back after the male buckle 10 is inserted into the female buckle 20, thus locking the buckle. The guide portion 121 extends away from the whistle 14 and has an arc-shaped chamfer at its end to guide the elastic prongs 12 when they are inserted into the female buckle 20, facilitating insertion. The pressing portion 122 connects the guide portion 121 to the male buckle body 11 and provides an elastic force when the elastic prongs 12 deform, so that the elastic prongs 12 are elastically deformed when the male buckle 10 is inserted into the female buckle 20. In addition, the thickness of the pressing portion 122 is greater than the thickness of the guide portion 121 to provide a larger contact surface when pressing, making pressing easier. The elastic part 123, located between the guide part 121 and the guide tongue 13, is a curved spring piece that, together with the pressing part 122, provides elasticity, resulting in higher elastic strength of the elastic pin 12. After the buckle is engaged, the elastic pin 12 will not easily deform due to the force generated by tension. The limiting protrusion 124 is disposed at the end of the free end of the elastic pin 12, and is disposed on the upper and lower surfaces perpendicular to the extension direction of the free end of the elastic pin 12, and is located on the side close to the guide tongue 13. It abuts against the corresponding structure of the female buckle 20, preventing the male buckle 10 from being pulled out arbitrarily after it is inserted into the female buckle 20. The specific abutting structure will be described in detail below in conjunction with the corresponding structure of the female buckle 20.

[0028] The guide tongue 13 is a guide structure set on the axis of symmetry of the two elastic pins 12. Its extension direction is consistent with the extension direction of the elastic pins 12. The edges of the guide tongue 13 are provided with arc chamfers to guide the elastic pins 12 when they are inserted into the female buckle 20, so as to facilitate insertion.

[0029] The whistle 14 is located at the end of the male buckle body 11 away from the elastic pin 12, and includes a mouthpiece 141, a resonance cavity 142 connected to the mouthpiece 141, a sound hole 143 on the resonance cavity 142, and an anti-slip part 144 on the outer shell of the resonance cavity 142.

[0030] The air nozzle 141 is a rectangular protrusion on the male buckle body 11. The protrusion is perpendicular to the extension direction of the elastic pin 12. An air passage is provided inside the protrusion along the protrusion direction. The air passage communicates with the resonance cavity 142 and gradually narrows from the opening to the connection with the resonance cavity 142.

[0031] The resonance cavity 142 is a hollow cavity disposed on the male buckle body 11, one end of which is connected to the air nozzle 141, and the other end is provided with an opening for airflow.

[0032] The sound-emitting hole 143 is disposed on the side wall of the resonance cavity 142 and located near the mouthpiece 141. The opening direction of the sound-emitting hole 143 is perpendicular to the extension direction of the air passage of the mouthpiece 141. The air passage of the sound-emitting hole 143 away from the mouthpiece 141 is inclined and is aligned with the gradually narrowing inner wall of the air passage of the mouthpiece 141 to form an inclined plane, thereby realizing the sound-producing principle of the whistle: the airflow enters a gradually narrowing gap from the mouthpiece, the airflow speed increases, and it is cut by the inclined plane of the sound-emitting hole, causing high-speed airflow turbulence. The turbulent airflow entering the resonance cavity resonates, thereby producing a sharp sound.

[0033] The anti-slip part 144 is disposed on the outer wall of the resonance cavity 142 and is located on the same side as the sound-emitting hole 143 to facilitate anti-slip when holding the hand. It can be multiple raised strips or multiple regularly arranged raised dots, and there is no specific limitation here.

[0034] The strap connecting buckle 15 is a common backpack strap length adjustment buckle, used to pass the strap through it. It is existing technology and should be well known to those skilled in the art, so its structure and function will not be described in detail here.

[0035] The female buckle 20 is an insertion cavity made of plastic injection molding and integrally formed. It includes an insertion port 21, a guide groove 22 disposed in the insertion port 21, two pressing ports 23 disposed on both sides of the guide groove 22, four guide strips 24 respectively disposed at the pressing ports 21, and a wing clip 25 disposed at the end of the female buckle 20 away from the insertion port 21.

[0036] The width of the insertion port 21 is sufficient to accommodate both elastic prongs 12 simultaneously. The guide groove 22 is located in the center of the insertion port 21 and is sized to precisely accommodate the insertion of the guide tongue 13, ensuring that the male buckle 10 does not wobble after being inserted into the female buckle 20. The guide groove 22 is open at both ends in the insertion direction, facilitating the removal of snow from the buckle when used in environments such as snowy conditions. Furthermore, an arc-shaped guide structure is provided at the opening of the guide groove 22 near the insertion port 21 to guide the insertion of the guide tongue 13.

[0037] The pressing openings 23 are located on both sides of the female buckle 20 perpendicular to the opening direction of the insertion port 21, and have an overall inwardly concave arc structure, so that when the elastic pins 12 are inserted into the female buckle 20, both sides protrude from the pressing openings 23. The pressing openings 23 communicate with the insertion port 22, so that the pressing part 122 passes through it when the buckle is fastened.

[0038] The guide strip 24 is arranged along the arc of the pressing port 24 on the inner wall of the female buckle 20. It can be imagined that when the male buckle 10 is inserted into the female buckle 20, the limiting protrusion 124 and the guide strip 24 abut against each other, and along the arc structure of the guide strip 24, the elastic pin 12 is deformed inward. When the male buckle 10 is in the position of being fully inserted into the female buckle 20, it is at the end of the guide strip 24 and cannot abut against the limiting protrusion 124. The elastic pin 12 rebounds. At this time, the limiting protrusion 124 and the guide strip 24 are misaligned. The elastic pin 12 must be pressed inward to pull out the male buckle 10. Meanwhile, the end edge of the guide strip 24 away from the insertion port 21 abuts against the limiting protrusion 124 to strengthen the structure and make the elastic pin 12 less likely to deform inward when subjected to vertical tension in the insertion direction of the buckle, thereby unlocking the buckle and enhancing the buckle's fastening strength.

[0039] The wing clip 25 is disposed on the female buckle 20, including a slot 251 and a latch 252 disposed on one side of the slot 251.

[0040] The slot 251 is a through slot with a circular body. The extension direction of the slot body is perpendicular to or slightly inclined to the extension direction of the elastic pin 12, so as to insert a ring-shaped item into the slot 251 and form a snap-fit ​​structure.

[0041] The latch 252 is an opening on one side of the slot 251, located on the side of the slot 251 away from the elastic pin 12, and communicating with the interior of the slot 251. It is used to insert a ring-shaped item from the latch 252 into the slot 251. The opening at the connection between the latch 252 and the slot 251 occupies less than 1 / 4 of the circumference of the circular groove of the slot 251 to prevent the ring-shaped item stuck in the slot 251 from falling out. Specifically, the size of the opening at the connection between the latch 252 and the slot 251 affects the pulling force of the wing clip 25. In actual production, the size of the opening of the latch 252 can be set according to the actual required pulling force. For example, in this embodiment, the pulling force of the wing clip 25 is greater than 15 kg. The gap at the end of the latch 252 away from the slot 251 is smaller than the gap at the connection point with the slot 251, so as to form an inclined guide portion, which facilitates inserting a ring-shaped item from the latch 252 into the slot 251.

[0042] Therefore, it can be imagined that when users are outdoors, items such as water bottles, umbrellas, and lamps that they need to carry can be attached to a ring structure and snapped into the wing clip 25. This allows for quick retrieval through the snap-fit ​​action, eliminating the need to hold the equipment in one's hand and greatly improving convenience outdoors.

[0043] The main bodies of the male buckle 10 and the female buckle 20 can be arc-shaped, and after being fastened, they will form an arc shape to prevent mistaken connection.

[0044] Compared with existing technologies, the outdoor wing clip buckle with whistle provided by this utility model, by setting the whistle 14 on the male buckle 10, not only prevents the whistle from being accidentally lost during outdoor activities, but also allows users to quickly use it in emergencies without having to search through pockets or backpacks. By setting the wing clip 25 on the female buckle 20, it replaces the limitation of traditional buckles that can only fix braided straps. Through the ring structure, various products such as umbrellas, water bottles, and lamps can be connected to the female buckle 20, and tools can be quickly fixed and retrieved by inserting the male buckle 10, greatly increasing the functionality for outdoor use and meeting various user needs.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
