By adjusting the extension length of the resistance-increasing plate, the magnitude of water resistance experienced during underwater resistance training can be adjusted.

Description

Technical Field

[0001] This utility model relates to the technical field of underwater training equipment, and in particular to a dual-cavity floating variable resistance dumbbell suitable for underwater training. Background Technology

[0002] Dumbbells are a common piece of fitness equipment, but the conventional way of lifting dumbbells can easily cause joint and muscle damage. Training in water can effectively avoid injury.

[0003] Existing underwater dumbbells typically use long plates to increase resistance. Since the plates are fixed to the dumbbells, the resistance remains constant and cannot be adjusted to suit different users. This makes it difficult for people with less strength to use them, and for people with more strength to get a workout. Furthermore, the buoyancy of the dumbbells cannot be adjusted, and they can only move from bottom to top in the water. They cannot perform pressing exercises by overcoming buoyancy, resulting in a limited range of applications. Utility Model Content

[0004] This utility model discloses a dual-chamber floating variable resistance dumbbell suitable for water training, aiming to solve the technical problem that the buoyancy of the dumbbell cannot be adjusted, and it can only move from bottom to top in water, making it impossible to perform pressing training by overcoming buoyancy, resulting in a limited range of applications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dual-chamber variable resistance dumbbell suitable for water training, comprising a resistance adjustment unit and a buoyancy adjustment unit:

[0007] The resistance adjustment unit includes a resistance-increasing plate and a dumbbell shell. A spring telescopic rod is rotatably mounted through one side of the dumbbell shell. A knob is fixedly mounted on one end of the spring telescopic rod, and a volute plate is fixedly mounted on the other end of the spring telescopic rod. A volute plate has a volute groove inside. A round rod is slidably mounted on the volute plate through the volute groove. One end of the round rod is fixedly mounted on the resistance-increasing plate.

[0008] The buoyancy adjustment unit includes a water inlet valve, one end of which is fixedly connected to a water bladder, and one side of which is fixedly connected to a connecting plate.

[0009] In a preferred embodiment, a retaining ring is fixedly installed on one side of the resistance-increasing plate, and a retaining block is fixedly installed on one side of the knob, with the inner wall of the retaining ring and the retaining block in a sliding insertion fit.

[0010] In a preferred embodiment, the spring telescopic rod is composed of a telescopic rod and a spring, with the two ends of the telescopic rod respectively mounted on a knob and a worm gear plate, and the two ends of the spring respectively mounted on a knob and a dumbbell housing.

[0011] In a preferred embodiment, the dumbbell housing has a through groove inside, and the resistance-increasing plate is slidably installed with the dumbbell housing through the through groove.

[0012] In a preferred embodiment, the inner wall of the connecting plate is slidably inserted into the resistance plate, and a water inlet is provided on one side of the dumbbell shell. The dumbbell shell is fixedly installed with the water inlet valve through the water inlet.

[0013] In a preferred embodiment, a dumbbell handle is threaded onto one side of the dumbbell housing, and the volute plate is slidably mounted on the inner wall of the dumbbell housing.

[0014] As can be seen from the above, the dual-chamber floating variable resistance dumbbell suitable for water training provided by this utility model has the following technical effects:

[0015] Firstly, when athletes are training with dumbbells underwater, they pull the knob outward to disengage the locking block from the slot ring, and then rotate the knob to make the spring extension rod and the worm gear rotate together. The worm gear has a worm-shaped groove inside, and when the worm gear rotates, the worm-shaped groove and the round rod work together to make the resistance plate expand outward or retract inward. By adjusting the extension length of the resistance plate, the amount of water resistance encountered during resistance training in the water can be adjusted.

[0016] Secondly, by opening the water inlet valve, water will enter the connecting plate and the water bladder, squeezing out the air inside the connecting plate and the water bladder. The water bladder and the connecting plate maintain a sealed state. The buoyancy of the dumbbell can be adjusted by the amount of water injected into the water bladder and the connecting plate, allowing for autonomous switching between resistance and anti-buoyancy training.

[0017] Thirdly, during underwater resistance training, the self-locking mechanism is achieved through the cooperation of the locking ring and the locking block. After adjusting the extension length of the resistance-increasing plate, it is not easy to retract due to external forces, making it convenient to use during resistance training.

[0025] Reference Figures 1-4 A dual-chamber variable resistance dumbbell suitable for water training, comprising a resistance adjustment unit 100 and a buoyancy adjustment unit 200:

[0026] The resistance adjustment unit 100 includes a resistance-increasing plate 101 and a dumbbell shell 102. A spring telescopic rod 107 is rotatably mounted through one side of the dumbbell shell 102. A knob 103 is fixedly mounted at one end of the spring telescopic rod 107, and a volute plate 105 is fixedly mounted at the other end of the spring telescopic rod 107. The volute plate 105 has a volute groove inside. The volute groove allows the dumbbell shell 102 to open or retract together when the volute plate 105 is rotated, thereby adjusting the water resistance. A round rod 106 is slidably mounted on the volute plate 105 through the volute groove. One end of the round rod 106 is fixedly mounted on the resistance-increasing plate 101.

[0027] The buoyancy adjustment unit 200 includes a water inlet valve 201, one end of which is fixedly connected to a water bladder 202, and one side of the water bladder 202 is fixedly connected to a connecting plate 203. The water inlet valve 201, the water bladder 202 and the connecting plate 203 play a sealing role, and the buoyancy can be adjusted by discharging the water inside, so as to realize anti-buoyancy training.

[0028] In this embodiment, when the athlete performs underwater dumbbell training, by pulling the knob 103 outward, the locking block 109 disengages from the locking ring 108. Then, by rotating the knob 103, the athlete causes the spring telescopic rod 107 and the worm gear plate 105 to rotate together. The worm gear plate 105 has a worm-shaped groove inside. When the worm gear plate 105 rotates, the worm-shaped groove cooperates with the round rod 106, which can drive the drag-increasing plate 101 to expand outward or retract inward. By adjusting the drag-increasing plate 101... The telescopic length allows for adjustment of the water resistance encountered during resistance training in water. By opening the inlet valve 201, water enters the connecting plate 203 and the water bladder 202, expelling the air inside. The water bladder 202 and the connecting plate 203 maintain a sealed state. The buoyancy of the dumbbell is adjusted by the amount of water injected into the water bladder 202 and the connecting plate 203, enabling autonomous switching between resistance and anti-buoyancy training.

[0029] In a preferred embodiment, a slot ring 108 is fixedly installed on one side of the resistance plate 101, and a locking block 109 is fixedly installed on one side of the knob 103. The inner wall of the slot ring 108 and the locking block 109 are in sliding engagement.

[0030] In this embodiment, self-locking is achieved through the cooperation of the slot ring 108 and the locking block 109. After the extension length of the resistance-increasing plate 101 is adjusted, it is not easy to retract due to external force, which is convenient for use during resistance training.

[0031] In a preferred embodiment, the spring telescopic rod 107 is composed of a telescopic rod and a spring. The two ends of the telescopic rod are respectively mounted on the knob 103 and the worm gear plate 105, and the two ends of the spring are respectively mounted on the knob 103 and the dumbbell housing 102.

[0032] In this embodiment, the retractable and resetting characteristic of the spring telescopic rod 107 ensures that the locking block 109 will not be pulled out due to non-human influence after it is locked into the locking groove ring 108, thus making the self-locking effect more stable.

[0033] In a preferred embodiment, a through groove is provided inside the dumbbell housing 102, and the resistance-increasing plate 101 is slidably installed with the dumbbell housing 102 through the through groove.

[0034] In this embodiment, the extension length of the resistance-increasing plate 101 is adjusted by sliding the resistance-increasing plate 101 inside the dumbbell housing 102.

[0035] In a preferred embodiment, the inner wall of the connecting plate 203 is slidably inserted into the resistance plate 101, and a water inlet is provided on one side of the dumbbell housing 102. The dumbbell housing 102 is fixedly installed with the water inlet valve 201 through the water inlet.

[0036] In this embodiment, the connecting plate 203 and the resistance-increasing plate 101 are slidably connected, so that the resistance-increasing plate 101 is fully guided when sliding inside the dumbbell shell 102, and will not be skewed or jammed.

[0037] In a preferred embodiment, a dumbbell handle 104 is threaded onto one side of the dumbbell housing 102, and a volute plate 105 is slidably mounted on the inner wall of the dumbbell housing 102.

[0038] In this embodiment, dumbbell plates can be added to both ends of the dumbbell grip 104 by threading the dumbbell shell 102 to the dumbbell grip 104, thereby further increasing the intensity of resistance training.

[0039] Working principle: When using the device, athletes pull the knob 103 outward to disengage the locking block 109 from the slot ring 108 during underwater dumbbell training. Then, they rotate the knob 103, causing the spring telescopic rod 107 and the worm gear plate 105 to rotate together. The worm gear plate 105 has a worm-shaped groove inside. When the worm gear plate 105 rotates, the worm-shaped groove cooperates with the round rod 106 to drive the resistance-increasing plate 101 to expand outward or retract inward. By adjusting the extension length of the resistance-increasing plate 101, the magnitude of water resistance encountered during resistance training in the water can be adjusted.

[0040] By opening the water inlet valve 201, water will enter the connecting plate 203 and the water bladder 202, squeezing out the air inside the connecting plate 203 and the water bladder 202. The water bladder 202 and the connecting plate 203 will maintain a sealed state. The buoyancy of the dumbbell can be adjusted by the amount of water injected into the water bladder 202 and the connecting plate 203.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Substitutions may include replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the scope of protection of this utility model.
