Description

Technical Field

[0001] This utility model relates to the field of diving equipment, and in particular to adjustable and secure fins. Background Technology

[0002] When engaging in underwater sports, fins are typically worn to provide users with more flexible movement. Fin manufacturers, in order to make the fins more flexible in their fit and adjustable to accommodate different foot sizes, typically consist of a foot sleeve that covers the forefoot and an adjustable foot strap. The distance between the foot strap and the foot sleeve is adjusted to fit the user's foot shape, preventing pressure on the foot or the fins from easily slipping off due to improper sizing. This ensures a secure fit. However, the reliability of fins relies solely on the material itself, and the risk of failure due to material deterioration or maintenance issues cannot be effectively prevented. Therefore, adjustable fins have been developed. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0004] The adjustable flipper includes a flipper body, on both sides of the flipper body are formed connecting protrusions and a fastening adjustment mechanism hinged to one side of the connecting protrusions, and a heel strap body with both ends connected to the fastening adjustment mechanism via a single-ring buckle. The distance between the heel strap body and the flipper body can be adjusted by the fastening adjustment mechanism.

[0005] Preferably, the fastening adjustment mechanism includes a universal joint hinged to the connecting protrusion, a connecting rod formed at one end of the universal joint, an adjusting ring connected to the connecting rod, and a protective shell connecting the connecting rod and the adjusting ring. An adjusting screw rotates through the adjusting ring, and one end of the adjusting screw is injection molded to form a buckle connected to the single-ring buckle of the heel strap. The other end of the adjusting screw is threaded to the connecting rod.

[0006] Preferably, one end of the connecting rod and the adjusting ring are located inside the protective shell, and the protective shell has a limiting groove formed inside to limit the connecting rod and the adjusting ring. The connecting rod has a protrusion that protrudes outward and is locked inside the limiting groove. The protective shell is composed of an upper cover and a lower cover.

[0007] Preferably, the upper cover and the lower cover are joined to form a channel, and a pin is inserted into the channel. A pin spring is elastically provided inside the channel and is elastically connected to the pin. The pin spring causes the pin to move elastically inside the channel. A locking groove is formed on the outer periphery of the adjusting ring to engage with the pin. The upper cover and the lower cover are also joined to form a limiting cylinder, and the other end of the pin is formed with a U-shaped groove to engage with the limiting cylinder.

[0008] Preferably, the adjusting ring is provided with a screw hole for the adjusting screw to rotate and fix, and the screw hole passes through the adjusting ring.

[0009] Preferably, a screw mounting hole and a bolt mounting hole are provided between the universal joint and the connecting protrusion. The screw mounting hole is formed inside the connecting protrusion, and the bolt mounting hole is formed at the upper and lower ends of the universal joint. A screw is inserted into the bolt mounting hole, and a locking screw is inserted into the bolt mounting hole.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-10 In this embodiment of the utility model, the adjustable flipper includes a flipper body 1, with connecting protrusions 4 and a fastening adjustment mechanism hinged to one side of the connecting protrusions 4 on both outer sides of the flipper body 1, and a heel strap 2 with both ends connected to the fastening adjustment mechanism via a single-ring buckle. The gap between the heel strap 2 and the flipper body 1 can be adjusted through the fastening adjustment mechanism to adapt to various sizes of the user's feet, effectively lock the required size to achieve a tight fit, and ensure the comfort of the heel strap 2 when it fits the user's heel during use.

[0029] The fastening and adjusting mechanism includes a universal joint 3 hinged to the connecting protrusion 4, a connecting rod 17 formed at one end of the universal joint 3, an adjusting ring 11 connected to the connecting rod 17, and a protective shell 7 connecting the connecting rod 17 and the adjusting ring 11. An adjusting screw 15 rotates through the adjusting ring 11, and one end of the adjusting screw 15 is injection molded to form a buckle 5 connected to the single-ring buckle of the heel strap 2. The other end of the adjusting screw 15 is threadedly connected to the connecting rod 17, so that the adjusting screw 15, together with the adjusting ring 11 and the buckle 5, is threadedly connected to the connecting rod 17.

[0030] One end of the connecting rod 17 and the adjusting ring 11 are respectively located inside the protective shell 17. The protective shell 17 has a limiting groove 19 formed inside to limit the connecting rod 17 and the adjusting ring 11. The connecting rod 17 has a protruding protrusion 18 that is stuck inside the limiting groove 19. The protective shell 17 is composed of an upper cover (not shown in the figure) and a lower cover (not shown in the figure). When the upper cover and the lower cover are closed, one end of the connecting rod 17 and the adjusting ring 11 can be clamped and fixed, so that the connecting rod 17 and the adjusting ring 11 can be further connected through the protective shell 17, and it is more convenient for subsequent disassembly and assembly.

[0031] The upper and lower cover shells are joined to form a channel 14, and a pin 8 is inserted into the channel 14. A pin spring (not shown in the figure) is elastically provided inside the channel 14 and is elastically connected to the pin 8. The pin spring causes the pin 8 to move elastically within the channel 14. A retaining groove (not shown in the figure) is formed on the periphery of the adjusting ring 11 to engage with the pin 8. This allows the pin 8 to be elastically inserted into the retaining groove via the pin spring, limiting the position of the adjusting ring 11 and preventing it from continuing to rotate via the adjusting screw 15 and buckle 5, thus preventing the tension of the heel strap 2 from constantly changing and causing discomfort in the user's heel. The upper and lower cover shells are also joined together to form a limiting cylinder 13, and the other end of the pin 8 is formed with a U-shaped groove 9 that is engaged with the limiting cylinder 13. When the pin 8 is pushed by the pin spring and the U-shaped groove 9 is engaged with the limiting cylinder 13, the other end of the pin 8 moves out from the locking groove on the periphery of the adjusting ring 11, thereby releasing the limiting effect on the adjusting ring 11. At this time, the adjusting ring 11 is rotated by the adjusting screw 15 and the buckle 5, thereby adjusting the tension of the heel strap 2. This solves the inconvenience caused by the need to pull back forcefully when preparing equipment in the traditional way, and also ensures that the direction can be finely adjusted in an emergency, thereby ensuring the safety of the user and increasing reliability.

[0032] The adjusting ring 11 is provided with a screw hole 16 for the adjusting screw 15 to rotate and fix, and the screw hole 16 passes through the adjusting ring 11.

[0033] A screw mounting hole 6 and a screw mounting hole 10 are provided between the universal joint 3 and the connecting protrusion 4. The screw mounting hole 6 is formed inside the connecting protrusion 4, and the screw mounting hole 10 is formed at the upper and lower ends of the universal joint 3. A screw is inserted into the screw mounting hole 6 (not shown in the figure), and a locking screw is inserted into the screw mounting hole 10 (not shown in the figure). When the universal joint 3 is snapped onto the connecting protrusion 4, the screw mounting hole 10 and the screw mounting hole 6 are aligned with each other. At this time, the locking screw inside the screw mounting hole 10 is threadedly connected to the screw, so that the universal joint 3 can move and swing on one side of the connecting protrusion 4 through the connection between the locking screw and the screw.

[0034] The heel strap 2 is provided with a buckle 12 that is connected and limited to the buckle 5. The heel strap 2 is made of soft rubber material. When the heel strap 2 is connected to the buckle 5, the tension generated by the buckle 12 when it is wrapped can prevent the heel strap 2 from slipping out of the buckle 5.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
