[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Depend on Figures 1 to 4 The present invention discloses an adjustable counterweight device for an aluminum bow handle, comprising a positioning seat 1, a sealing cover 2, several weights 3, and a locking bolt 4. The positioning seat 1, the sealing cover 2, and the weights 3 are embedded inside the aluminum bow handle. The locking bolt 4 connects the sealing cover 2 and the aluminum bow handle. The weights 3 pass through the positioning seat 1, which is located inside the sealing cover 2. The positioning seat 1 has several weight positioning through holes 5 that match the weights 3. The center of the positioning seat 1 has a center groove 6 that matches the sealing cover 2. The center support 7 is located in the middle of the interior of the sealing cover 2. The center support 7 has bolt mounting holes 8 that match the locking bolt 4. A rubber round gasket 20 is provided between the bottom surface of the weights 3 and the aluminum bow handle. An embedded weight chamber, adapted to the counterweight components, is pre-installed inside the bow handle. A rubber round pad 20 is placed inside the embedded weight chamber for cushioning. A threaded hole, compatible with the locking bolt 4, is also provided inside the embedded weight chamber. The positioning seat 1, sealing cover 2, and weights 3 are then embedded into the aluminum bow handle and secured with the locking bolt 4. Weight adjustment is achieved by adding or removing the number of weights 3, allowing for customization to meet the athlete's individual strength needs (such as adjusting the total weight of the bow handle based on training intensity, shooting distance, and personal force application habits), breaking away from traditional fixed weight systems. By overcoming the limitations of the bow handle, the same bow can be adapted to different athletes or different usage scenarios of the same athlete, improving the versatility and adaptability of the bow. At the same time, weights 3 can be installed inside different weight positioning holes 5 to change the torque of the counterweight components relative to the bow handle's center of gravity reference point, thereby adjusting the overall center of gravity position of the bow (such as adjusting the center of gravity to be forward, backward, left, or right). This helps athletes optimize the stability of holding the bow when shooting, reduces the error caused by the center of gravity shift when the arrow is launched, and improves shooting accuracy, which is especially suitable for professional competitions and high-intensity training scenarios. The locking bolt 4 has an internal hexagonal slot 9 at the middle position of its top, which can be adjusted by using a hexagonal wrench; A foam ring 10 is provided on the inner surface of the weight positioning through hole 5. The weight 3 is inserted into the foam ring 10, which can reduce the impact force between the weight 3 and the positioning seat 1 and play a role in buffering and noise reduction. The bottom surface of the positioning seat 1 is provided with a rubber gasket 11, the side of the bottom end of the sealing cover 2 is provided with a rubber gasket 22, and the bottom end of the central support 7 is provided with a rubber gasket 33. The rubber gasket 11 and the positioning seat 1, the rubber gasket 22 and the sealing cover 2, and the rubber gasket 33 and the central support 7 are all bonded together with structural adhesive, which can fill the gap at the connection, improve the tightness of the connection, and at the same time have a sealing function. Polyurethane foam pads 14 are provided on the inner surface of the sealing cover 2 and the side of the central support 7, which can reduce the impact force between the weight 3 and the sealing cover 2 and play a role in buffering and noise reduction. The sealing cover 2 has a buckle groove 15 at the middle position of both ends of the top. The sealing cover 2 has an annular groove 16 at the bottom of the side. A rubber sealing ring 17 is installed inside the annular groove 16. The sealing cover 2 has an annular groove 28 at the top of the side. A rubber sealing ring 29 is installed inside the annular groove 28. When disassembling the counterweight device, a tool can be inserted into the slot 15 to facilitate the removal of the sealing cover 2 from the aluminum handle. Rubber sealing ring 17 and rubber sealing ring 29 can improve the sealing performance and prevent rainwater and dust from entering the interior of the sealing cover 2 through the gap between the sealing cover 2 and the aluminum handle.

[0016] In operation, by embedding the positioning seat, sealing cover, and weights inside the aluminum bow handle, a concealed counterweight compartment design is achieved, maintaining the integrity of the bow handle's appearance and solving the aesthetic and safety issues of traditional external counterweights. Multiple weights and independent weight positioning holes facilitate the addition or removal of weights. While maintaining a constant total weight, the torque of the counterweight assembly relative to the bow handle's center of gravity is altered by moving the weights to different positions, thereby adjusting the overall center of gravity of the bow. The use of foam rings, rubber gaskets (one, two, three), polyurethane foam pads, and rubber round gaskets provides cushioning and noise reduction, while also reducing the impact force of the weights on the bow handle, positioning seat, and sealing cover, thus extending their service life. Rubber sealing rings (one and two) improve the sealing at the contact point between the sealing cover and the bow handle, preventing rainwater and dust from entering the counterweight device.
