Technical Field

[0001] This utility model relates to the field of swimming equipment technology, and in particular to a detachable flipper. Background Technology

[0002] As we all know, fins are a common tool in underwater sports. They are foot covers that provide powerful propulsion for swimming and diving. When swimming, the large surface area of ​​the fins can provide powerful propulsion without having to use the hands to generate power, thus freeing the hands to do other work.

[0003] Currently, fins mainly consist of a fin plate and a shoe body (sole) worn on the user's foot. In conventional designs, the fin plate and shoe body are integrated and cannot be removed. However, with continuous design advancements, fins have become increasingly diverse. But this diversity primarily involves changes in the shape, color, and structure of the fin plate – essentially just replacing the fin plate. Different users, different water types, and different swimming needs require different fin plates, necessitating the purchase of multiple fins and the need to remove the fins before changing them, causing considerable inconvenience for consumers.

[0023] like Figures 1 to 4 As shown, this embodiment provides a detachable flipper, including a shoe body 1 and a flipper plate 2. The shoe body 1 has an open wearing space 11. The shoe body 1 has a buckle 12 for locking the user's wearing at the wearing space 11. The front end of the shoe body 1 is provided with a plug end 13. The flipper plate 2 is provided with a receiving port 21. The plug end 13 is aligned and inserted into the receiving port 21 and fastened by a locking fastener 3.

[0024] The main purpose of this embodiment is to realize a detachable design for the fins, so that the shoe body 1 and the fin plate 2 can be freely separated to allow the shoe body 1 to be freely assembled with other fin plates 2, making the fins more personalized and diversified, enhancing the practical value of the fins, and facilitating daily use by consumers.

[0025] Furthermore, various other locking forms may exist for the locking device 3. In this embodiment, the receiving port 21 is designed in a "U" shape. The locking device 3 includes a mating cavity 31 on both sides of the mating end 13 and a mating plug 32 on both ends of the receiving port 21. The outer side of the mating cavity 31 is provided with a locking opening 33. A spring block 34 that can be pressed inward is provided in the locking opening 33. The outer end of the mating plug 32 is torn outward to form an outward elastic protrusion 36. With this structure, during assembly, the materials' elasticity (the shoe body 1 and webbed feet 2 are made of plastic, both possessing a certain degree of elasticity) allows for direct insertion, aligning the receiving port 21 with the inserting end 13. The insert plug 32 is then inserted into the inserting cavity 31, leaving sufficient space for the protrusion 36 to enter the locking opening 33 until it is positioned below the spring block 34. The protruding end of the protrusion 36 then touches the side wall of the locking opening 33, thus securing it. When disassembly is required, simply press the spring block 34. Because the protrusion 36 is below the spring block, both protrusion 36 and spring block 34 are simultaneously pressed inward, providing sufficient space in the inserting cavity for the protrusion 36 to retract. With both protrusions 36 pressed down, the receiving port 21 and the inserting end 13 can be separated, thus separating the shoe body 1 and the webbed feet 2.

[0026] Furthermore, since the protrusion is a component that needs to be pressed frequently, in order to improve its service life and strength, at least one inclined reinforcing rib 37 is provided on the inner end face of the plug 32 and at the connection with the protrusion 36 in this embodiment. In this way, after the protrusion 36 is repeatedly pressed and deformed, the strength of the connection between the protrusion 36 and the plug 32 can be improved by this reinforcing rib 37, so as to avoid easy breakage.

[0027] Furthermore, to facilitate assembly without pressing the protrusion 36, the front end of the protrusion 36 in this embodiment is connected to the plug 32, and the rear end of the protrusion 36 gradually tilts outward, so that the protrusion 36 will be automatically pressed down as it is inserted.

[0028] Furthermore, to prevent positional shift after assembly, the receiving port 21 and the mating end 13 in this embodiment are respectively provided with a limiting block 22 and a limiting opening 14 with a shape corresponding to the limiting block 22. When the mating end 13 is inserted into the receiving port 21, the limiting block 22 is inserted into the limiting opening 14. In this way, the limiting block 22 and the limiting opening 14 can form a mutual constraint, thereby avoiding positional shift.

[0029] Furthermore, to further enhance the tightness of the assembly and prevent detachment during use, this embodiment also includes a pin 4. The pin 4 is provided with an external thread, and a pin hole 41 is provided on the outer wall of the mating cavity 31. A nut 42 is fixedly provided on the mating plug 32. When the mating end 13 is aligned and inserted into the receiving port 21, the pin hole 41 is aligned with the inner ring of the nut 42, and the pin 4 is inserted through the pin hole 41 and forms a threaded lock with the nut 42. In this way, the insertion of the pin 4 and the connection between the pin 4 and the nut 42 can limit the occurrence of detachment.

[0030] Furthermore, to prevent the pin 4 from rotating automatically and then disengaging during use, a hanging ring 43 is hinged to the top of the pin 4 in this embodiment. A protruding post 44 is provided at the edge of the receiving port 21. When the pin 4 and the nut 42 are threaded together, the hanging ring 43 rotates and engages with the post 44, thus preventing the pin 4 from rotating automatically. It should be noted that the hanging ring 43 is also made of a material with a certain elastic deformation capacity, such as stainless steel. When engaging with or disengaging from the post 44, it can be done simply by pulling and pressing it into or prying it off the post 44. Additionally, for ease of manual operation, the top of the post 44 in this embodiment is a mushroom-shaped head.

[0031] Furthermore, to facilitate a more secure rotation of the pin 4, a square hole 45 is provided on the end face of the pin 4 in this embodiment, which can be fastened using a tool. The specific shape of the square hole 45 can be designed as a straight line, a cross, a polygonal groove, etc., depending on the different tools designed.

[0032] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
