[0025] ​As shown in the attached figure, this utility model provides a quick-release adjustable weight dumbbell, including a dumbbell handle 11 and counterweights connected to the left and right ends of the dumbbell handle 11. The counterweights include counterweight A1 and counterweight B2. A boss 3 is provided on one side of counterweight A1, and a round hole 4 that mates with the boss 3 is provided on one side of counterweight B2. The boss 3 of counterweight A1 is inserted into the round hole 4 of counterweight B2 along the axial direction. The radial relative movement of counterweight A1 and counterweight B2 is restricted by the boss 3 and the round hole 4. A groove 5 is provided on the top of the boss 3 of counterweight A1. A sliding block 6 that can move up and down is provided inside counterweight B2. A slanted tongue 7 that mates with the groove 5 is provided on the sliding block 6. A spring 8 is provided at the bottom of counterweight B2 below the sliding block 6. The sliding block 6 is reset by the spring 8. The axial relative movement of counterweight A1 and counterweight B2 is restricted by the slanted tongue 7 being engaged in the groove 5.

[0026] The top of the boss 3 bends downward to form a groove 5. When the counterweight A1 is inserted into the counterweight B2 along the axial direction, the inclined surface 1 of the top of the boss 3 presses against the inclined surface 2 of the oblique tongue 7, thereby pushing the sliding block 6 to move downward so that the oblique tongue 7 is inserted into the groove 5. After the counterweight A1 and the counterweight B2 are engaged as one, the oblique tongue 7 disengages from the groove 5 after the sliding block 6 inside the counterweight B2 continues to be subjected to a downward force, thereby releasing the axial restriction of the counterweight A1 and the counterweight B2. After the axial restriction of the counterweight A1 and the counterweight B2 is released, the counterweight A1 continues to move along the axial direction, and the boss 3 disengages from the round hole 4 of the counterweight B2, thereby releasing the radial restriction of the counterweight A1 and the counterweight B2.

[0027] In addition, this utility model can provide a base support 9 at the bottom of the counterweight B2, thereby increasing the stability of the dumbbell. A limiting plate 10 can also be installed on one side of the counterweight B2 to restrict the vertical movement of the sliding block 6. A circular hole 4 is formed on the limiting plate 10. A boss 3 is also provided on the other side of the counterweight B2, and a slot 5 is provided on the top of the boss 3. Radial relative movement between the counterweight B2 and adjacent counterweight B2 is restricted by the boss 3 and the circular hole 4, and axial relative movement is restricted by the oblique sliding tongue 7 engaging the slot 5. This allows for quick assembly and disassembly of multiple counterweights, thereby quickly adjusting the weight of the dumbbell. (See attached diagram.) Figure 12 As shown.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0029] As attached Figure 1 As shown, the boss of counterweight A is fitted into the round hole of counterweight B along the axial direction. At this time, the fit between the boss and the round hole restricts the relative movement of counterweight A and counterweight B in the radial direction.

[0030] As attached Figure 2 To be continued Figure 4As shown, when counterweight A is inserted into counterweight B along the axial direction, the inclined surface at the top end of the boss of counterweight A presses against the inclined surface of the inclined sliding tongue in counterweight B. Under the action of the inclined sliding force, the spring is subjected to a compressive force greater than its elastic force, thereby causing the sliding block to be pushed downward.

[0031] As counterweight A continues to move axially, the oblique sliding tongue of the boss and counterweight B are at a critical point, as shown in the attached figure. Figure 5 and attached Figure 7 As shown, the compressive force on the spring is still greater than its elastic force; when the end of the boss just exceeds the inclined surface of the sliding tongue, the spring immediately rebounds, locking the sliding tongue into the groove of the boss, as shown in the attached figure. Figure 6 and attached Figure 8 As shown, the axial movement of counterweights A and B is restricted and blocked at this time.

[0032] Through the above steps, the axial and radial movements of counterweight A and counterweight B are restricted and locked, thus firmly binding counterweight A and counterweight B together. This allows for quick installation and adjustment of counterweight A and counterweight B to increase the weight of the dumbbell.

[0033] When the downward external pressure on the sliding block is greater than the spring force, the sliding block slides downward, causing the oblique sliding tongue to disengage from the slot of the boss, thus releasing the axial restriction between counterweight A and counterweight B. This allows counterweight A to move axially, and the oblique sliding tongue disengages from the slot of counterweight A, thereby releasing the radial restriction, as shown in the attached figure. Figure 9 and attached Figure 10 As shown; this step allows for quick removal of counterweight A and counterweight B, thereby reducing the weight of the dumbbell.

[0034] To address the problems of instability and random scrolling of control buttons in current round dumbbells and weights, which hinder adjustments for fitness enthusiasts, this invention uses a base, as shown in the attached diagram. Figure 11 As shown, this increases the stability of the dumbbells and the operability of the product.

[0035] The contents not described in detail in this specification are existing technologies known to those skilled in the art. The standard parts used can be purchased from the market, and the irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment adopt conventional models in the existing technology, and the circuit connection adopts conventional connection methods in the existing technology, which will not be described in detail here.

[0036] The utility model is not limited by the above implementation mode, other any change, modification, substitution, combination, simplification under not departing from the utility model's spiritual essence and principle should be equivalent replacement mode, all contain in the utility model's protection scope.
