Description
Technical Field
[0001] This utility model relates to the field of swimming training equipment technology, and in particular to a weighted fingertip clip. Background Technology
[0002] One of the technical challenges in swimming training for beginners and intermediate swimmers lies in the athlete's blurred end-effector perception, leading to problems such as misaligned entry point, awkward arm recovery, and inaccurate exit point. Since the fingertips are highly sensitive, this can be cleverly utilized in swimming training to optimize stroke performance. Therefore, there is an urgent need to design a device that can improve end-effector perception to assist athletes in training. Utility Model Content
[0003] The purpose of this invention is to provide a weight-bearing fingertip clip that solves the technical problem of unclear end-point perception in existing technologies. The various technical effects of the preferred solutions among the many technical solutions provided by this invention are detailed below.
[0004] To achieve the above objectives, the present invention provides the following technical solution: The weighted fingertip clip provided by this utility model includes a clamping plate, a connecting arm, and a counterweight. There are two clamping plates, and the connecting arm is disposed between the two clamping plates. The counterweight is provided on both clamping plates.
[0005] Preferably, the center of gravity of the counterweight is close to the head end of the counterweight.
[0006] Preferably, the counterweight is disposed inside the clamping plate.
[0007] Preferably, the counterweight is made of tungsten alloy.
[0008] Preferably, the distance between the head ends of the two clamps is smaller than the distance between their tail ends.
[0009] Preferably, an arc-shaped limiting plate is provided on one side of the clamping plate, and there is a gap between the limiting plates on the two clamping plates.
[0010] Preferably, the end faces of the two clamping plates that are facing away from each other are arc-shaped from the periphery to the center.
[0011] Preferably, each of the two clamping plates has a groove on its opposite end face that gradually recesses from both sides to the middle.
[0012] Preferably, the number of connecting arms is two, and they are respectively located near both ends of the clamping plate.
[0013] Preferably, the counterweight is a plate-shaped structure, and the width of the front end of the counterweight near the head end of the clamp is greater than the width of the rear end near the tail end of the clamp.

[0014] The application employs the above technical solution and has at least the following beneficial effects: The weighted fingertip clamp includes clamps, connecting arms, and counterweights. There are two clamps, and the connecting arm is disposed between the two clamps. The counterweights are provided on both clamps. In this application, by adding counterweights to the clamps, the weight of the weighted fingertip clamp is increased. This allows athletes to more clearly perceive the centrifugal inertia generated by their arms during cyclical movements, thereby enabling them to better control the precision of their end-effector movements. At the same time, due to the trajectory inertia, the athlete's arm can be more relaxed and guided by inertia, thus forming a natural and smooth arm return movement.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] A specific embodiment of this utility model provides a weight-bearing fingertip clip, as shown in the attached figure. Figure 1 - Appendix Figure 5 As shown, it mainly includes a clamping plate 1, a connecting arm 2, and a counterweight 3. There are two clamping plates 1, the connecting arm 2 is located between the two clamping plates 1, and a counterweight 3 is provided on each of the two clamping plates 1.
[0021] The space between the two clamps 1 forms a space to accommodate the fingers, and the spaces on both sides of the connecting arm 2 form a space to accommodate two fingers. The setting of the counterweight part 3 can increase the weight of the weighted fingertip clamp, thereby increasing its inertia. This allows the athlete to more clearly perceive the eccentric inertia brought out by the arm during the periodic movement, so that the athlete can better control the precision of the end movement. At the same time, because of the trajectory inertia, the athlete's arm can be more relaxed and follow the inertial guidance, thereby forming a natural and smooth arm return movement.
[0022] In a specific embodiment of this application, the center of gravity of the counterweight 3 is close to the head end of the counterweight 3. The head end refers to the position close to the tip of the finger when the weighted fingertip clip is in use.
[0023] In some embodiments, the counterweight 3 is disposed inside the clamping plate 1 and can be formed by metal insert injection molding process. This method makes the combination of the clamping plate 1 and the counterweight 3 more compact and prevents the clamping plate 1 and the counterweight 3 from shaking or separating.
[0024] Specifically, the material of this counterweight 3 can be tungsten alloy, or other metal materials. Compared with the plastic material of the outer clamp 1, the metal material has a higher density, which can provide greater weight while ensuring that the weight-bearing finger clip has a small volume.
[0025] The weight of each counterweight 3 can range from 6 grams to 15 grams.
[0026] Different individuals use weighted finger clips of varying weights. For example, the combined weight of the two weight sections (3) on both sides of a weighted finger clip used by teenagers ranges from 12 to 20 grams, such as 16 grams. Adults use weighted finger clips with a combined weight of the two weight sections (3) on both sides ranging from 22 to 30 grams, such as 26 grams. The weight can be increased beyond these limits, but prolonged use increases the risk of rotator cuff injury.
[0027] In some embodiments, in conjunction with the appendix Figure 3 As shown, the distance between the ends of the two clamps 1 is less than the distance between their ends, where the end pointed to is the left end and the end pointed to is the right end. This ensures that the two clamps 1 are set at a certain angle, so that when in use, the user's fingers can be inserted from the end with the larger distance between the two clamps 1 to the other end, thus adapting to the shape of the user's fingers. The angle between the two clamps 1 can range from 2° to 5°.
[0028] In some embodiments, an arc-shaped limiting plate 4 is provided on one side of the clamping plate 1, and there is a gap between the limiting plates 4 on the two clamping plates 1. The limiting plate 4 can play a limiting role and can play a certain role in preventing it from falling off.
[0029] In some embodiments, the end faces of the two clamping plates 1 that are opposite to each other are arc-shaped from the periphery to the center, which can minimize the resistance on their outer surfaces.
[0030] Specifically, each of the two opposing end faces of the clamping plates 1 has a first groove 5 that gradually recesses from both sides to the center. This first groove 5 is deeper in the center of the clamping plate 1 along its width and becomes shallower on both sides. The first groove 5 is wider near the head end of the clamping plate 1 and narrower near the tail end. By setting this first groove 5, athletes can better find the fingertip anchor point after entering the water. Because it amplifies the water control sensation of the fingertips in the initial stage of the grab, athletes can more clearly perceive the starting point of force.
[0031] In some embodiments, there are two connecting arms 2, which are respectively located near the two ends of the clamping plate 1. The two connecting arms 2 are provided to ensure the connection strength between the two clamping plates 1 and to ensure the stability of the structure.
[0032] In some embodiments, in conjunction with the appendix Figure 5 As shown, the counterweight 3 is a plate-shaped structure. The width of the front end of the counterweight 3 near the head end of the clamping plate 1 is greater than the width of the rear end near the tail end of the clamping plate 1, forming a structure that is wide at the front and narrow at the rear, so that its center of gravity is forward. A second groove 6 is provided on the counterweight 3. The groove wall of the second groove 6 gradually thickens from the front end to the rear end and the direction of the side walls. This shape is similar to the shape of the first groove 5.
