Abstract
Description
Technical Field
[0001] This invention relates to a fin, and more particularly to a fin web plate mounting mechanism. Background Technology
[0002] Freediving is an extreme sport in which divers dive into the water in one breath without carrying any air tanks or equipment. It typically requires three pieces of equipment: fins, a mask, and a snorkel. Among these, the fins are the most crucial, as their design, materials, and structure all affect the diver's performance in the water. Fins generally consist of three components: foot covers, fins, and fin guides. Fins usually have a phasing section and a mounting section, with an angle between the two sections so that they are not on the same horizontal plane.
[0003] In conventional fins, especially those with fins made of composite materials and detachable from the foot cover, the fins are typically glued to the bottom of the foot cover using adhesives or secured with screws or clips. However, this adhesive method of assembling fins requires skill and experience, creating a high barrier to entry. It also presents drawbacks such as inconvenience, complex and time-consuming procedures, and the possibility of uneven adhesive application affecting the fixation structure. Furthermore, because the contact area between the fin and the foot cover slot cannot move relative to each other, when the fin is subjected to stress and undergoes bending deformation, its deformation differs from that of the foot cover due to material differences. This can cause them to pull against each other, preventing the fin from effectively utilizing its bending properties and potentially damaging the fin. Furthermore, while using screws or clamps to fasten fins and foot covers makes it convenient for users to install and remove fins, it still has problems such as more installation steps and the need to use specific tools. Moreover, the practice of drilling holes in the fins to facilitate the fastening method creates weak points in the fin structure. Since the fastening position cannot be moved, the area around the hole will be continuously subjected to applied pressure, causing stress concentration and leading to damage to the fin structure.
[0004] In light of this, the present invention aims to explore how to connect a fin assembly structure to the bottom of the foot cover for assembling fins, so as to form a detachable joint mechanism to form a accommodating structure that can restrain and fix the fins, thereby achieving the purpose of flexibly assembling and disassembling the fins. At the same time, the movable mechanism provided in the assembly structure can generate relative displacement to provide users with the function of adaptively adjusting the relative position between the fins and the foot cover, thereby improving the deficiencies of the above-mentioned conventional technology and making it convenient for users to adjust the fins to a better position for easier kicking according to their different needs and foot shapes, thus improving the smoothness of underwater kicking. Summary of the Invention
[0005] The main objective of this invention is to provide a fin mounting mechanism with detachable and adjustable assembly positions, allowing users to adjust and assemble a fin onto a fin foot cover according to their own needs or usage habits.
[0006] To achieve the above objectives, the present invention provides a fin mounting mechanism for flexing a fin, which is installed under a fin foot cover for movably assembling a fin. It comprises: a base member having a base body, at least one sliding seat, and a first moving unit, the sliding seat and the first moving unit being disposed on the base body, and the base body for assembling the fin foot cover; and a pressure plate member for assembling the base member, the pressure plate member having a pressure plate body, a movable area, and a second moving unit, the movable area being recessed in the top surface of the pressure plate body, and the second moving unit being disposed on the pressure plate body corresponding to the first moving unit. In the body, when the pressure plate is assembled with the base, the movable area accommodates the slide, and the first moving unit and the second moving unit are correspondingly assembled to generate a relative displacement; and a fastener is provided for assembling the pressure plate. The fastener is provided with a clamping part, a pair of flexible parts and a pair of clamping units. One end of the clamping part is connected to one end of the flexible part on each opposite side, and the other end of each flexible part is connected to a clamping unit. A groove is recessed on each of the corresponding two inner sides between the pair of clamping units so that the web plate can be inserted into the pair of grooves and assembled between the pressure plate and the fastener.
[0007] In a preferred embodiment, the base member has two slides and a first groove. The slides are respectively disposed on opposite sides of the base body, and the first groove is recessed at the center of the base body surface between the pair of slides. The side of each slide away from the first groove is inclined outward at a first angle, so that the side of each slide and its bottom surface form a first acute angle. The sidewalls on opposite sides of the movable area are inclined towards the center at a second angle corresponding to the first angle, so that the bottom surface of the movable area and each sidewall form a second acute angle. Accordingly, the pair of slides is movably inserted between the opposite sidewalls of the movable area by the first acute angle and the second acute angle. The first moving unit is an actuating rod, and the base component is further provided with a bearing seat. The bearing seat is located on the other side of the base body opposite to the two sides of the pair of slides, corresponding to the first groove, and the bearing seat has a through hole. The second moving unit is a slider, which is located at the center of one side of the active area, corresponding to the first groove, and the slider has a through hole. When the pressure plate component is assembled with the base component, each slide is inserted between the side wall of the opposite sides of the active area and the slider, so that the slider is engaged with the first groove, and the actuating rod is inserted through the through hole and the through hole to generate the relative displacement and adjust the relative position between the pressure plate component and the base component. The actuator rod is provided with a feed part for the feed screw, and the inner side wall of the through hole is provided with a thread corresponding to the feed part, so that the actuator rod can use the feed part and the thread to generate relative displacement between the pressure plate and the base by rotating, thereby adjusting the connection position of the web plate assembly.
[0008] In another preferred embodiment, the base member is provided with a single slide, and the opposite sides of the slide are respectively inclined outward at a first angle, so that each side of the slide and its bottom surface respectively form a first acute angle. The opposite sides of the movable area are respectively inclined towards the center at a second angle corresponding to the first angle, so that the bottom surface of the movable area and each side wall respectively form a second acute angle. Accordingly, the slide is movably inserted between the opposite side walls of the movable area by the first acute angle and the second acute angle. The first moving unit is a gear, and the second moving unit is a rack. When the base member assembles the pressure plate member, the gear engages with the rack, thereby rotating the first moving unit moves the pressure plate member.
[0009] The outer contour of the pressure plate corresponds to one end of the web plate, with the front end of the pressure plate body bent downwards at a limiting angle to form a limiting surface. The pressure plate body also has a sidewall located at the periphery of its rear bottom surface. Each groove is recessed into the sidewall of each clamping unit and extends to its front edge to form an insertion port for inserting and accommodating the two peripheral portions of the web plate near the fold angle. The inner top surface of each groove has a first upper guide surface, a second upper guide surface, and a third upper guide surface, and the inner bottom surface has a first lower guide surface, a second lower guide surface, and a third lower guide surface to guide the web plate into the grooves. At the position corresponding to the third lower guide surface, the second and third upper guide surfaces connect to form an arc-convex microstructure. An anti-slip unit is provided on one side of the top surface of the clamping part to increase frictional resistance.
[0010] The fin mounting mechanism is further equipped with a fastening element, and a fastening hole is provided on each of the opposite sides of the front part of the pressure plate body. The clamping unit has a fastening opening corresponding to the fastening hole. The fastening element passes through the fastening opening and is locked in the fastening hole, thereby ensuring the tightness and fit of the clamping unit and the front part of the pressure plate body. The pressure plate and the fastener are assembled by assembly methods including injection molding, adhesive bonding, ultrasonic welding, heated molding, or locking or riveting of assembly elements, so that one periphery of the clamping part is tightly connected to the side wall of the plate, the upper periphery of each flexible part abuts against the side wall of the plate, and the upper edges of each clamping unit abut against and press against the opposite sides of the front part of the pressure plate body.
[0011] In summary, the present invention has the following characteristics:
[0012] 1. Through the arrangement of the pressure plate and the fastener, the clamping unit, the flexible part, the clamping part, the pressure plate body including the limiting surface and the plate sidewall form a web plate accommodating space that has both restraint and positioning functions, so that the user can simply insert the web plate to complete the assembly operation of fixing it to the fin foot cover, achieving a quick and easy operation to meet practical needs.
[0013] 2. By connecting the side wall of the plate with the periphery of one side of the clamping part and the upper periphery of the pair of flexible parts, the main body of the pressure plate formed by the plate can restrain the vertical displacement of the web plate. This minimizes the clearance after the web plate is engaged, thereby avoiding continuous tight pressure at a specific position of the web plate. This can better reduce stress concentration and prevent adverse effects or even damage to the web plate.
[0014] 3. In addition to using the pressure plate and the fastener to hold the fin, the pair of sidewalls of the active area and the slide base, as well as the first moving unit and the second moving unit, are used to realize the engagement mechanism, the limiting mechanism and the moving mechanism. This allows for a flexible and adaptable position adjustment range while assembling the pressure plate and the base, allowing users to move the position of the fin according to their different body types, leg types and shoe sizes, so as to adjust the fin to a better position where it is easier to kick, thereby improving the smoothness of movement in the water and the comfort of kicking.

Detailed Implementation
[0031] To enable those skilled in the art to clearly understand the contents of this invention, please refer to the following description and accompanying drawings.
[0032] Please see Figure 1This is a schematic diagram of the architecture of a first preferred embodiment of the present invention. As shown in the figure, the fin mounting mechanism 1 includes a base component 10, a pressure plate component 11, and a fastener 12, for mounting under a fin foot cover 2 to movably assemble a fin plate 3. The base component 10 has a base body 100, at least one slide 101, and a first moving unit 104, and the slide 101 and the first moving unit 104 are disposed on the base body 100. The pressure plate component 11 has a pressure plate body 110, a movable area 111, and a second moving unit 112. The movable area 111 is recessed in the top surface of the pressure plate body 110, and the second moving unit 112 is disposed on the pressure plate body 110 corresponding to the first moving unit 104. The fastener 12 is provided with a clamping part 120, a pair of flexible parts 121 and a pair of clamping units 122. One end of the clamping part 120 is connected to one end of the flexible part 121 on each of the opposite sides, and the other end of each flexible part 121 is connected to a clamping unit 122. A groove 1220 is recessed on the corresponding two inner sides of the pair of clamping units 122.
[0033] The base body 100 is used to assemble the fin foot cover 2. When the pressure plate 11 is assembled with the base 10, the movable area 111 accommodates the slide 101, and the first moving unit 104 and the second moving unit 112 are correspondingly assembled to generate a relative displacement. Furthermore, after the fastener 12 is assembled with the pressure plate 11, the web plate 3 is inserted into the pair of grooves 1220 and assembled between the pressure plate 11 and the fastener 12. Accordingly, the web plate 3 is installed under the fin foot cover 2 through the fin web plate mounting mechanism 1.
[0034] As mentioned above, please refer to the following: Figures 2 to 4A , Figure 4B , Figure 5A , Figure 5BThese are schematic diagrams of the second preferred embodiment of the present invention. As shown in the figure, the base member 10 is provided with a single slide 101, which is disposed on the base body 100, and the opposite sides of the slide 101 are respectively inclined outward at a first angle, so that each side of the slide 101 and its bottom surface respectively form a first acute angle. The outer contour of the pressure plate member 11 corresponds to one end of the web plate 3, so that the outer contour of the pressure plate member 11 is approximately and fits the outer contour of the web plate 3 mounting part. Accordingly, the front end of the pressure plate body 110 is bent downward at a limiting angle 1100 to form a limiting surface 1101, and the pressure plate body 110 is provided with a plate side wall 114, which is disposed at the periphery of the rear bottom surface of the pressure plate body 110. Corresponding to the configuration of the slide 101, the side walls on opposite sides of the movable area 111 are inclined toward the center at a second angle corresponding to the first angle, so that the bottom surface of the movable area 111 and each side wall form a second acute angle 1110. A non-slip unit 1200 may be provided on one side of the top surface of the clamping part 120, for example, a strip or dot-shaped anti-slip structure with a high coefficient of friction protruding from the plane, and each groove 1220 is recessed in the side wall of each clamping unit 122 and extends to its front edge to form an insertion port. The inner top surface of each groove 1220 is provided with a first upper guide surface 1221, a second upper guide surface 1222 and a third upper guide surface 1223, and the inner bottom surface is provided with a first lower guide surface 1224, a second lower guide surface 1225 and a third lower guide surface 1226.
[0035] The first moving unit 104 can be a gear, such as a gear with a handle, and is located on one side of the base body 100 with the handle protruding from the base body 10. The second moving unit 112 can be a rack and is located on one side of the top surface of the pressure plate body 110, corresponding to the gear's position. When the base body 10 assembles the pressure plate 11, the gear engages with the rack, and the first acute angle engages with the second acute angle 1110, allowing the slide 101 to be movably inserted between the two opposite side walls of the movable area 111. Accordingly, by rotating the first moving unit 104 with the handle protruding from the base body 10, the pressure plate 11 can be moved to adjust the assembly position. Furthermore, when the pressure plate 11 and the fastener 12 are assembled by means of encapsulation injection, adhesive bonding, ultrasonic welding, heated molding, or assembly element locking or riveting, one periphery of the clamping part 120 is tightly connected to the side wall 114 of the plate, the upper periphery of each flexible part 121 abuts against the side wall 114 of the plate, and the upper edges of each clamping unit 122 abut against and press against the opposite sides of the front part of the pressure plate body 110 (including the limiting surface 1101). When the web plate 3 is inserted from the insertion port between the pressure plate 11 and the fastener 12, the peripheral parts of both sides of the web plate 3 are guided into the grooves 1220 by the first to third upper guide surfaces 1221 to 1223 and the first to third lower guide surfaces 1224 to 1226, so that one end of the web plate 3 is accommodated between the pressure plate 11 and the fastener 12 near the corner. At this time, the web plate 3 contacts the anti-slip unit 1200, which increases the frictional resistance between it and the clamping part 120, thereby improving the tightness and reliability of the installation of the web plate 3.
[0036] Incidentally, in another possible implementation of this embodiment, an arcuate microstructure (not shown) can be formed between each of the second upper guide surfaces 1222 and each of the third upper guide surfaces 1223 at the positions corresponding to each of the third lower guide surfaces 1226 inside each of the slots 1220, so as to improve the ease of embedding the web plate 2 into each of the slots 1220, and at the same time achieve the effect of ensuring that the web plate 2 is not easy to slip out after being embedded. Furthermore, based on this consideration, the fin plate mounting mechanism 1 can be provided with a fastening element (not shown), and correspondingly, a fastening hole (not shown) is provided on each of the opposite sides of the front of the pressure plate body 110. The clamping unit 122 is provided with a fastening opening (not shown) corresponding to the fastening hole. The fastening element passes through the fastening opening and is locked in the fastening hole, thereby ensuring the tightness and fit between the clamping unit 122 and the front of the pressure plate body 110, so as to effectively improve the fastness of the fin plate 3 assembled in the fin plate mounting mechanism 1.
[0037] Please see Figures 6 to 9A , Figure 9B , Figure 10A, Figure 10B , Figure 11A , Figure 11B The figures show schematic diagrams of the third preferred embodiment of the present invention. As shown, the fin mounting mechanism 1 is designed to be mounted under a fin foot cover 2 to enable the movable assembly of a fin plate 3. It includes a base 10, a pressure plate 11, and a fastener 12. The corresponding engagement mechanism, limiting mechanism, and moving mechanism between the base 10, the pressure plate 11, and the fastener 12 allow the user to install the fin plate 3 onto or remove it from the fin foot cover 2. The relative installation position between the fin plate 3 and the fin foot cover 2 can be flexibly adjusted as needed.
[0038] The base component 10 is installed under the fin foot cover 2, and the base component 10 has a base body 100, two slides 101, a first groove 102, a bearing 103, and a first moving unit 104. The base body 100 is symmetrical, for example, a slightly rectangular shape with left and right symmetry and a main long axis. In order to facilitate subsequent assembly operations, the front end of the base body 100, that is, the bottom surface corresponding to the toe direction of the fin foot cover 2, can be gradually reduced towards the top surface in an arc so that the height of the front end of the base body 100 is smoothly reduced to be less than the height of the center of the base body 100. The slides 101 are rectangular in shape, with their major axes aligned with the major axis of the main body and located on opposite sides of the base body 100. A first groove 102 is recessed at the center of the surface of the base body 100 between the slides 101. Each slide 101 has its side away from the first groove 102 inclined outwards at a first angle, forming a first acute angle with its bottom surface. A bearing 103 is located on the other side of the base body 100 opposite to the sides of the slides 101, corresponding to the first groove 102. The bearing 103 has a through-hole 1030. The first moving unit 104 can be a connecting rod.
[0039] The pressure plate 11 is used to assemble the base 10, and the pressure plate 11 has a pressure plate body 110, a movable area 111, a second moving unit 112, a second groove 113, and a plate sidewall 114. The pressure plate body 110 is disposed opposite to one end of the fin plate 3, so that its outline is similar and fits the outline of the mounting part and part of the padding part of the fin plate 3, for covering the fin plate 3, and the movable area 111 is recessed on the top surface of the pressure plate body 110. The second moving unit 112 can be a slider, which has a through hole 1120 and is disposed at the center of one side of the movable area 111, corresponding to the position of the first groove 102. The second groove 113 is recessed at the top surface of the active area 111. The second groove 113 passes through the second moving unit 112 and may integrate the space of the through hole 1120 or be separated from the space of the through hole 1120. The side walls on opposite sides of the active area 111 are inclined towards the center at a second angle corresponding to the first angle, so that the bottom surface of the active area 111 and each side wall form a second acute angle 1110. The front end of the pressure plate body 110 is bent downward at a limiting angle 1100 to form a limiting surface 1101, which is used to restrain and position the insertion position of the web plate 3 at the angle corresponding to the web plate 3. The plate side wall 114 is arranged around the periphery of the bottom surface of the rear end of the pressure plate body 110.
[0040] The fastener 12 is used to assemble the pressure plate 11, and the fastener 12 is provided with a clamping portion 120, a pair of flexible portions 121, and a pair of clamping units 122. One end of the clamping portion 120 extends to both sides to form the flexible portions 121, and each flexible portion 121 is connected to a clamping unit 122 at its end. The flexible portions 121 have better elasticity relative to the main body of the clamping portion 120 and the pair of clamping units 122, allowing limited deformation in any direction, and an anti-slip unit 1200 may be provided on one side of the top surface of the clamping portion 120 to increase frictional resistance. The two inner sides of the pair of clamping units 122 are respectively recessed with a groove 1220. Each groove 1220 extends from the side wall of each clamping unit 122 to the port of each clamping unit 122 to form an insertion port. The inner top surface of the groove 1220 is provided with a first upper guide surface 1221, a second upper guide surface 1222 and a third upper guide surface 1223, and the inner bottom surface is provided with a first lower guide surface 1224, a second lower guide surface 1225 and a third lower guide surface 1226.
[0041] When the fastener 12 is connected to the pressure plate 11, the clamping part 120 is tightly connected to the side wall 114 of the plate, and the upper edges of each clamping unit 122 respectively abut against and press against the opposite sides of the front section of the pressure plate body 110, including the limiting surface 1101. Thus, the upper and lower guide surfaces 1221-1226 in the pair of grooves 1220, the limiting surface 1101 and the front section of the pressure plate body 110 form a space that can restrain the forward and backward and up and down displacement of the web plate 3. At the same time, the side wall 114 of the plate is connected to one side periphery of the clamping part 120 and the upper periphery of the pair of flexible parts 121. The pressure plate body 110, which is added in this way, forms a space that can restrain the left and right displacement of the web plate 3 mounting part. Accordingly, a space is formed between the fastener 12 and the pressure plate 11 to accommodate the fin plate 3, limiting its forward, backward, up, down, left, and right movement. This minimizes the clearance after the fin plate 3 is attached, ensuring the stability of the assembled fin and the reliability of the product. Next, when the pressure plate 11 is assembled with the base 10, each slide block 101 is movably inserted between the two opposite side walls of the movable area 111 via the first acute angle engaging with the second acute angle 1110. The slider 112 is embedded in the first groove 102, and the actuating rod passes through the through opening 1030 and the through hole 1120. Therefore, when the pair of slide blocks 101 are movably accommodated in the movable area 111, a relative displacement is generated through the corresponding assembly of the first moving unit 104 and the second moving unit 112, allowing adjustment of the relative position between the pressure plate 11 and the base 10.
[0042] Please refer to this again. Figure 12A , Figure 12B When the web plate 3 is inserted through the pair of insertion ports on both sides, the web plate 3 is guided deep into the groove 1220 by the aforementioned guide surfaces 1221-1226 until the peripheral portions of the web plate 3 near the folded corner are fully inserted into the web plate receiving space. In this embodiment, an arcuate microstructure is formed between the second upper guide surface 1222 and the third upper guide surface 1223 corresponding to the second lower guide surface 1225 and the third lower guide surface 1226. This arcuate microstructure guides the web plate 3 to slide smoothly forward when it is inserted between the pressure plate 11 and the fastener 12, thereby improving the ease and smoothness of insertion and ensuring that the web plate 2 is not easily slipped out after insertion. Furthermore, the actuator rod may be provided with a feed part (not shown) for a feed screw, and the inner side wall of the through hole 1120 is provided with a thread (not shown) corresponding to the feed part, so that the actuator rod can rotate to utilize the mechanism principle between the feed part and the thread, so that the actuator rod can generate relative displacement with the slider through rotation, thereby forming a limited range of movement between the pressure plate body 110 and the base body 100, thereby adjusting the assembly position of the web plate 3.
[0043] Accordingly, the operation of assembling the fin plate 3 to the fin foot cover 2 using the fin plate mounting mechanism 1 is completed. This allows the user to rotate the actuator rod according to personal needs or usage habits, using the feed part to push the slide blocks 101 between the pair of side walls of the active area 111, adjusting the relative position between the pressure plate 11 and the base 10, and thus adjusting the position of the fin plate 3 assembled to the fin foot cover 2. This allows for adjustment to a more optimal force application position when the user is wearing the fins and applying force in the water, improving the smoothness of kicking in the water, thereby reducing oxygen consumption and improving movement efficiency, and potentially reducing the severity and probability of sports injuries. Please refer to [link / reference needed]. Figure 13A , Figure 13B , Figure 13C , Figure 13D Based on the technical principle of kicking fins, when performing a forward kick, the user generates power from the thigh, and then the knee bends slightly and naturally in response to the resistance, transferring the power through the lower leg to the ankle. At this time, the ankle acts as a fulcrum between the leg and the fin plate 3, so it must be supported as much as possible to keep the instep flat to ensure sufficient power transmission. Here, when the kicking power is transmitted to the fin plate 3 through the fin foot cover 2 and the fin plate mounting mechanism 1, the position of the fin plate 3 in most conventional fins is close to... Figure 13A or Figure 13B As shown in the diagram, the extension axis FO of the fin plate 3 is close to the tibia of the lower leg. However, this deficiency means that when the fin plate 3 is subjected to water resistance, its load point is farther away from the ankle and more away from the central axis LO of the lower leg. This results in a larger torque being applied to the ankle, which is not conducive to the continuous movement. Furthermore, if the instep cannot be kept flat due to improper technique, the tibialis anterior muscle of the leg will also bear greater external force, causing leg fatigue and thus reducing movement efficiency. In other words, the preferred position of the fin plate 3 should be as shown in state (C), where the extension axis FO of the fin plate 3's paddling part should be as parallel and close as possible to the central axis LO of the lower leg. This allows the fin plate 3, the fin foot cover 2, and the user's leg to form a unified whole, resulting in better structural strength. This minimizes the torque on the ankle. At this point, the paddling part of the fin plate 3 is essentially part of the structure extending from the ankle, allowing for smoother use of the natural posture of the lower leg and thigh to more fully transfer the kicking power to the fin plate 3, thus improving movement efficiency. However, each user's body shape and leg size differ, and the fin plate 3 and fin foot cover 2 used by each user also vary in size. Therefore, the aforementioned preferred fin plate position cannot be precisely defined. Therefore, the present inventors propose a fin plate mounting mechanism 1, allowing users to test and adjust the position of the pressure plate 11 relative to the base 10 to find the optimal relative position of the fin plate 3 and the fin foot cover 2.
[0044] Incidentally, the base component 10 is connected to the swan shoe cover 2 via the base body 100. For commercial applications, the swan shoe cover 2 can be provided with the base component 10 directly connected, or it can be provided separately from the base component 10, to facilitate manufacturing or allow consumers to choose. After the fastener 12 is assembled with the pressure plate 11, the pressure plate 11 is then assembled with the base component 10. Considering the needs of commercial applications, the pressure plate 11 and the fastener 12 can be assembled using methods including injection molding, adhesive bonding, ultrasonic welding, heated molding, or component locking or riveting. This allows the pressure plate 11 and the fastener 12 to be provided to consumers as an integrated unit or as separate components; there are no limitations. Furthermore, the surfaces of the guide surfaces, such as the first upper guide surface 1221, the second upper guide surface 1222, the third upper guide surface 1223, the first lower guide surface 1224, the second lower guide surface 1225, and the third lower guide surface 1226, are not limited to being flat. Depending on the product type, the scope of product application, and research experience over the years, they can of course adopt curved or arc-shaped surface designs. Moreover, the guide surfaces are not set up with the concept of upper and lower surfaces corresponding to each other, so the positions of the upper and lower guide surfaces are not limited to being aligned and corresponding.
[0045] Furthermore, to account for the potential gap between the pressure plate 11 and the fastener 12 caused by the force exerted on the fin plate 3 during more intense diving activities such as competitive diving, which could affect the kicking feel, the fin plate mounting mechanism 1 can also provide a fastening element 13, such as... Figure 14 As shown, a fastening hole 1102 is provided on each of the opposite sides of the front part of the pressure plate body 110. The clamping unit 122 is provided with a fastening opening 1227 corresponding to the fastening hole 1102. The fastening element 13, such as screw, clip, clamp, pin and or detachable semi-permanent fastening part, passes through the fastening opening 1227 and is locked in the fastening hole 1102, thereby ensuring the tightness and fit between the clamping unit 122 and the front part of the pressure plate body 110, minimizing the clearance, enhancing the effect of fixing the web plate 3 and improving the product's application scope and market satisfaction.
