The dumbbell plates are arranged at both ends of the dumbbell rod. A locking device is provided on the curved surface of the dumbbell rod. The locking device includes four groups of locking mechanisms located on the same straight line. The distance between adjacent locking mechanisms is 2-3 mm. Each group of locking mechanisms includes an 'n'-shaped buckle and two grooves arranged at intervals. Both ends of the buckle are slidably connected in the grooves. A number of round holes are arranged at intervals on the buckle. A number of circular channels are arranged at intervals between the circular surfaces at both ends of the dumbbell rod. The channels are communicated with the grooves. The aperture of the channels is less than or equal to the aperture of the round holes. A pin shaft for fixing the buckle is arranged in the channels. Locking pieces for locking the pin shaft are arranged at both ends of the circular surface of the dumbbell rod.

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1 and Figure 2 , the present invention provides a technical solution:

[0021] A connecting structure between a handle for assisting in using a dumbbell and a dumbbell plate, including a handle 100. Round rods 130 are welded to both ends of the handle 100. A bearing 140 is sleeved on the outside of the round rod 130. A dumbbell plate 200 is sleeved on the bearing 140. External threads are provided on the outer wall of the bearing 140. A screw sleeve 150 is screwed on the outside of the bearing 140. The dumbbell plate 200 is pressed and installed on the round rod 130 through the screw sleeve 150;

[0022] It also includes a limiting component, and the bearing 140 is connected to the round rod 130 through the limiting component;

[0023] A rubber sleeve 101 is sleeved on the outside of the handle 100;

[0024] The handle 100 is composed of a first column body 110 and a second column body 120, and the first column body 110 and the second column body 120 are detachably connected through a fastening component.

[0025] During use, as Figure 3As shown, the dumbbell plate 200 is sleeved outside the bearing 140, and then the dumbbell plate 200 is fastened by turning the screw sleeve 150. Hold the handle 100 for training. Due to the function of the bearing 140, the dumbbell plate 200 and the handle 100 can rotate independently of each other, converting the sliding friction between the handle 100 and the hand into rotational friction, and then cooperating with the rubber sleeve 101 to effectively prevent the hand from getting calloused during training. The handle 100 can be disassembled into a first column body 110 and a second column body 120, which is convenient for replacing the rubber sleeve 101.

[0026] The fastening assembly includes a first screw 114 and a second screw 124. A first insertion rod 111 is integrally formed on the first column body 110. A first insertion slot 1111 is opened at the bottom of the first insertion rod 111. A first insertion hole 112 is opened inside the first column body 110. A first threaded hole 113 communicating with the first insertion hole 112 is opened on the first column body 110; the structures of the first column body 110 and the second column body 120 are centrosymmetrically arranged. At the corresponding positions of the second column body 120, there are a second insertion rod 121, a second insertion slot 1211, a second insertion hole 122, and a second threaded hole 123; during assembly, the second insertion rod 121 is inserted into the inside of the first insertion hole 112, and after the first screw 114 is screwed into the first threaded hole 113, its inner end is inserted into the inside of the second insertion slot 1211; the first insertion rod 111 is inserted into the inside of the second insertion hole 122, and after the second screw 124 is screwed into the second threaded hole 123, its inner end is inserted into the inside of the first insertion slot 1111. With the above design, it is convenient to disassemble and assemble between the first column body 110 and the second column body 120 by disassembling and assembling the first screw 114 and the second screw 124. By inserting the second insertion rod 121 into the inside of the first insertion hole 112 and the first insertion rod 111 into the inside of the second insertion hole 122, the overall stability of the handle 100 is improved.

[0027] The first threaded hole 113 is inclined inward, and the angle between it and the horizontal plane is between sixty and eighty degrees. With the above design, the inclination angle of the first threaded hole 113 can be set according to actual needs. Since the first threaded hole 113 is inclined, under the action of the first screw 114, the connection between the first column body 110 and the second insertion rod 121 is more stable. Similarly, the connection between the second column body 120 and the first insertion rod 111 is also more stable.

[0028] The limiting assembly includes a third screw 143. An annular connecting plate 142 is welded to the outer end of the inner ring of the bearing 140. The annular connecting plate 142 and the round rod 130 are connected by the third screw 143. With the above design, it is convenient to disassemble and assemble the bearing 140 by disassembling and assembling the third screw 143.

[0029] The inner side of the outer ring of the bearing 140 is welded with an annular limiting plate 141. With the above design, the limiting of the dumbbell plate 200 is improved through the action of the annular limiting plate 141.

[0030] The outer wall of the screw sleeve 150 is welded with a trapezoidal block 151. With the above design, it is convenient to twist the screw sleeve 150 through the trapezoidal block 151.

[0031] In summary:

[0032] Due to the function of the bearing 140, the dumbbell plate 200 and the handle 100 can rotate independently of each other, converting the sliding friction between the handle 100 and the hand into rotational friction, and then cooperating with the rubber sleeve 101, effectively preventing the hand from being calloused during training. The handle 100 can be disassembled into a first column body 110 and a second column body 120, facilitating the replacement of the rubber sleeve 101. The bearing 140, the first column body 110, and the second column body 120 are designed to be detachable, facilitating the replacement of each component;

[0033] By disassembling and assembling the first screw 114, it is convenient to disassemble and assemble between the first column body 110 and the second column body 120. By inserting the second insertion rod 121 into the interior of the first insertion hole 112 and the first insertion rod 111 into the interior of the second insertion hole 122, the overall stability of the handle 100 is improved;

[0034] The inner side of the outer ring of the bearing 140 is welded with an annular limiting plate 141, and the limiting of the dumbbell plate 200 is improved through the action of the annular limiting plate 141; it is convenient to twist the screw sleeve 150 through the trapezoidal block 151;

[0035] Since the first threaded hole 113 is inclined, under the action of the first screw 114, the connection between the first column body 110 and the second insertion rod 121 is made more stable. Similarly, the connection between the second column body 120 and the first insertion rod 111 is also made more stable.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
