Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1:

[0031] See also Figure 1-4 The present embodiment provides a magnetic quick-release anti-drop dumbbell, comprising a grip bar 1, a switch magnetic seat 2 magnetically plugged into both ends of the grip bar 1, and a counterweight 3 magnetically plugged into the switch magnetic seat 2;

[0032] Connecting blocks 11 are fixedly arranged at both ends of the grip rod 1, and trapezoidal grooves 111 are arranged on the connecting blocks 11;

[0033] A counterweight groove 31 is provided on one side of the counterweight body 3, and a trapezoidal protrusion 311 is fixedly provided in the counterweight groove 31;

[0034] A grip connection slot 21 is provided at one end of the switch magnetic base 2, and a counterweight connection slot 22 is provided at the other end. The grip connection slot 21 matches with the trapezoidal slot 111 on the grip 1, and the counterweight connection slot 22 matches with the trapezoidal protrusion 311 on the counterweight slot 31, so as to prevent the counterweight body 3 from falling off when the dumbbell moves quickly.

[0035] The outer surfaces of the connection block 11 and the grip connection groove 21 are matched rectangles, and a trapezoidal groove 111 is provided on the connection block 11, so that the connection block 11 forms two trapezoidal protrusions, and the grip connection groove 21 has a groove matched with the two trapezoidal protrusions, so that the connection block 11 of the grip 1 and the grip connection groove 21 are plugged, and the grip 1 and the grip connection groove 21 are non-slidable in the vertical direction of the grip 1, and the grip 1 is fixed by magnetism in the direction parallel to the grip 1, so that the grip 1 is firmly connected with the switch magnetic base 2;

[0036] The counterweight connecting groove 22 is trapezoidal in shape, and cooperates with the trapezoidal protrusion 311 in the counterweight groove 31, so that the switch magnetic base 2 and the counterweight body 3 cannot slide in the direction perpendicular to the handle 1, and are firmly connected to the switch magnetic base 2 and the counterweight body 3 by magnetic fixation in the direction parallel to the handle 1.

[0037] In this embodiment, the shape of the trapezoidal groove 111 on the handle 1 is perpendicular to the shape of the counterweight connecting groove 22, and the limiting direction of the handle 1 and the switch magnetic base 2 is perpendicular to the limiting direction of the switch magnetic base 2 and the counterweight body 3, further preventing the switch magnetic base 2 and the counterweight body 3 from falling off.

[0038] In this embodiment, the switch magnetic base 2 includes a magnetic switch 23, a first pole shoe 24 and a second pole shoe 25 which are magnetically slidably connected to the magnetic switch 23, the first pole shoe 24 and the second pole shoe 25 are made of soft ferromagnetic materials, a first spacer 26 and a second spacer 27 are arranged between the first pole shoe 24 and the second pole shoe 25, the first spacer 26 and the second spacer 27 are made of plastic material, the first pole shoe 24, the second pole shoe 25, the first spacer 26 and the second spacer 27 form a cavity, the shape of the cavity matches the magnetic switch 23, when the magnetic switch 23 rotates to the same direction as the first spacer 26 and the second spacer 27, the switch magnetic base 2 loses its magnetic attraction to the grip rod 1 and the counterweight 3, when the magnetic switch 23 rotates to a direction perpendicular to the first spacer 26 and the second spacer 27, the switch magnetic base 2 has a magnetic attraction to the grip rod 1 and the counterweight 3, so as to achieve the effect of quick disassembly and assembly, and the operation is simple and convenient.

[0039] In this embodiment, the surfaces of the grip connection groove 21 and the counterweight connection groove 22 are rough surfaces, which further increase the friction between the grip 1 and the counterweight 3 and the switch magnetic base 2, preventing the switch magnetic base 2 from falling off the grip 1 and the counterweight 3.

[0040] In this embodiment, the counterweight body 3 is in the shape of a hexagon. When the dumbbell is placed on the ground or on a table, the side surface of the hexagon contacts the bottom surface or the table surface, so that the dumbbell can be placed firmly and reduce accidental injuries caused by the rolling of the dumbbell.

[0041] Embodiment 2:

[0042] See also Figure 5-6 The difference between this embodiment and embodiment 1 is that a plurality of counterweight bodies 3 can be provided, and the counterweight bodies 3 are all connected by switch magnetic seats 2, and both ends of the handle 1 are connected to the switch magnetic seats 2 and the counterweight bodies 3 at intervals. The outer side of the counterweight body 3 can be provided with a connecting block 11 that is the same as that on the handle 1, so that the outer side of the counterweight body 3 is connected to the switch magnetic seat 2, so as to achieve the purpose of quickly increasing or decreasing the counterweight.

The first pole shoe 24, the second pole shoe 25, the first spacer 26, and the second spacer 27 form a hollow structure, and the magnetic switch 23 is inserted into the hollow part, the connecting block 11 is inserted into the grip connecting groove 21, and the counterweight connecting groove 22 is inserted into the counterweight groove 31. The magnetic switch 23 is rotated so that the handle position direction at the upper end of the magnetic switch 23 is perpendicular to the direction of the grip 1, so that the grip 1, the switch magnetic seat 2 and the counterweight body 3 are fastened. If it is necessary to increase the counterweight, the switch magnetic seat 2 and the counterweight body 3 can be directly magnetically matched and magnetically plugged with the previous counterweight body 3. The number of counterweight bodies 3 and the switch magnetic seat 2 at both ends of the grip 1 is the same. If it needs to be disassembled, the handle position direction at the upper end of the magnetic switch 23 is consistent with the direction of the grip 1, so that all accessories can be disassembled, which is convenient to carry and easy to operate.

[0044] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
