[0002] Dumbbells are simple equipment used to enhance muscle strength training. The main material of kinetic dumbbells is cast iron, and some are covered with a layer of rubber. They are used for muscle strength training and muscle compound movement training. Patients with low muscle strength due to motor paralysis, pain, long-term inactivity, etc. can hold dumbbells and use the weight of the dumbbells to perform active resistance exercises to train muscle strength.

[0003] For example, the Chinese patent with publication number CN210447958U discloses a dumbbell for quickly replacing counterweights, comprising a connecting rod, a lower counterweight box, an upper counterweight box and an installation box, wherein both ends of the connecting rod are fixedly connected with a first threaded rod, one side of the lower counterweight box is fixedly connected with a connecting sleeve, and the other side of the lower counterweight box is fixedly connected with a second threaded rod, and the lower counterweight box close to the connecting rod and two adjacent lower counterweight boxes are threadedly connected through the second threaded rod and the connecting sleeve; when using the device, the locking pin can be driven to move inward by controlling the pressing rod, and then the locking between the locking pin and the locking plate is released, and the upper counterweight box is opened, and the counterweight can be put into it, so that people can replace the counterweight according to their needs more conveniently and quickly, and will not delay people's exercise time too much, and can effectively improve the efficiency of exercise;

[0036] Embodiment 3 of the utility model of a dumbbell capable of quickly replacing weight plates

[0037] Reference Figure 1-Figure 5 As shown, the counterweight 1003 and the handle 1001 are both made of metal, and the surfaces of the counterweight 1003 and the handle 1001 are coated with an anti-rust coating. The outer surface of the handle 1001 is provided with a plurality of anti-slip textures between a pair of limit rings 1002, and the plurality of anti-slip textures are equidistantly distributed. Both ends of the handle 1001 are arranged in an arc shape. By setting the counterweight 1003 and the handle 1001 as metal materials, their strength can be improved. By coating them with an anti-rust coating, they can avoid being corroded by sweat. By setting the anti-slip texture on the handle 1001, the friction between it and the user's hand can be improved. By setting the two ends of the handle 1001 in an arc shape, the fixing block 2001 and the counterweight 1003 can be easily inserted.

[0038] Specifically, the working principle of the dumbbell with quickly replaceable weight plates is as follows: when in use, the user will put the weight blocks 1003 on both ends of the handle 1001 as appropriate according to his or her own training situation. Then, the user will align the mounting hole 2007 opened at the center of the fixed block 2001 with the handle 1001, and at the same time squeeze the pressure rods 2006 on both sides of the fixed block 2001. When the pressure rods 2006 are squeezed, the slidingly connected pressure blocks 2005 will be driven to move inward, and then the inclined surfaces of the wedge blocks 2003 will be squeezed by the two sides of the pressure blocks 2005, so that a pair of card blocks 2002 will move to both ends. At this time, the user will pass one end of the handle 1001 through the mounting hole 2007. When the fixed block 2001 moves to one side of the weight block 1003, the user will release the pressure rod 2006, and the pressure blocks 2005 will move inward. After the pressure is lost, the block 2002 is squeezed and reset under the elastic force of the spring 2007. The opposite surfaces of the block 2002 are set to an arc shape. When the block 2002 is reset, one end of the block 2002 is inserted into the annular groove 1004 provided on the handle 1001 to complete the fixation of the fixed block 2001. At this time, the fixed block 2001 and the limit ring 1002 fix the counterweight block 1003 at both ends of the handle 1001, which is convenient for the user to exercise. When the counterweight block 1003 needs to be replaced, it is only necessary to press the pressure rods 2006 on both sides of the fixed block 2001 to squeeze, and the pressure block 2005 squeezes the wedge blocks 2003 on both sides of the block 2002, so that the block 2002 is separated from the annular groove 1004, and the fixed block 2001 can be removed from the handle 1001, which is convenient and quick.

[0039] The above description is only the preferred implementation 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.
