[0028] In this embodiment, by configuring a separate mounting assembly 200 on the counterweight weight plate, only the mounting post 220 needs to be replaced when the mounting post 220 deforms or breaks, without having to replace the entire counterweight weight plate, thus reducing the usage cost of the adjustable dumbbell. Simultaneously, the connecting plate 210 is fixedly connected to the weight plate body 100 via a first connector, and the mounting post 220, connecting plate 210, and weight plate body 100 are fixedly connected via a second connector. The first connector, second connector, and connecting plate 210 provide good strength support for the mounting post 220, improving its support strength and making it less prone to breakage.
[0029] Preferably, please refer to the appendix. Figure 1The bell body 100 has a U-shaped bell rod receiving groove 110, which extends through the bell body 100 along its thickness direction. One end of the bell rod receiving groove 110 extends to the outer peripheral edge of the bell body 100, forming an opening on the outer peripheral edge. The mounting assembly 200 is located on the side of the bell rod receiving groove 110 away from the opening, and the first connector is located on the side of the second connector away from the bell rod receiving groove 110.
[0030] To further reduce the risk of breakage of the mounting post 220, the mounting assembly 200 can be made of a metal with a hardness of 120HB or higher. Specifically, the hardness of the connecting plate 210, mounting post 220, first connector, and second connector is greater than or equal to 120HB. Preferably, the mounting post 220 and connecting plate 210 can be made of Q235 carbon steel, and the first connector and second connector can be made of 304 stainless steel.
[0031] The bell body 100 has a recessed mounting groove on its side, and the connecting plate 210 is installed in the mounting groove. The shape of the connecting plate 210 is adapted to the shape of the mounting groove so that the connecting plate 210 is positioned in the mounting groove.
[0032] In some embodiments of this application, the mounting post 220 is provided with a first connecting hole 223, the connecting plate 210 is provided with a through second connecting hole 211, and the bell body 100 is provided with a third connecting hole 111. A first connector passes through the first connecting hole 223, the second connecting hole 211, and the third connecting hole 111 to fix the connecting plate 210, the bell body 100, and the mounting post 220 together. This arrangement simplifies the connection structure between the bell body 100 and the mounting assembly 200 and provides high support strength for the mounting post 220.
[0033] Preferably, the first connector is a first rivet 230, the first connecting hole 223 penetrates the mounting post 220 along the thickness direction of the bell body 100 and is a stepped hole, and the third connecting hole 111 penetrates the bell body 100 along the thickness direction of the bell body 100. The stepped surface 2231 of the stepped hole abuts against the first rivet 230. Specifically, the first rivet 230 includes a connected first rivet 230 head and a first rivet 230 post. The first rivet 230 head is located in the stepped hole and abuts against the stepped surface 2231. The first rivet 230 post passes through the stepped hole, the second connecting hole 211 and the third connecting hole 111 in sequence, and the end of the first rivet 230 post is pressed against the side of the bell body 100 away from the mounting post 220. Alternatively, the first rivet 230 head abuts against the side of the bell body 100 away from the mounting post 220, and the first rivet 230 post passes through the third connecting hole 111, the second connecting hole 211 and the stepped hole in sequence, and the end of the first rivet 230 post is pressed against the stepped surface 2231.
[0034] Of course, in other embodiments, the first connector is not limited to the above. For example, the first connector can also be a first bolt. In this case, the first connecting hole 223 is a threaded hole and the third connecting hole 111 penetrates the bell body 100. The first bolt passes through the third connecting hole 111 and the second connecting hole 211 in sequence and is screwed into the first connecting hole 223. Alternatively, the third connecting hole 111 is a threaded hole and the first connecting hole 223 penetrates the mounting post 220. The first bolt passes through the first connecting hole 223 and the second connecting hole 211 in sequence and is screwed into the third connecting hole 111.
[0035] In some embodiments of this application, the mounting post 220 is provided with a first positioning part, and the connecting plate 210 is provided with a second positioning part. The positioning and cooperation between the first positioning part and the positioning part can not only realize the mutual limiting between the connecting plate 210 and the mounting post 220 and improve the support strength of the mounting post 220, but also facilitate the assembly between the connecting plate 210 and the mounting post 220 and improve the production efficiency of the counterweight bell.
[0036] Preferably, the mounting post 220 includes a connected mounting section 221 and a positioning section 222. The mounting post 220 engages with the mounting teeth on the mounting plate via the mounting section 221. The positioning section 222 constitutes the first positioning part, and the second connecting hole 211 constitutes the second positioning part. The positioning section 222 is located on the side of the mounting section 221 closest to the bell body 100, and is inserted into the second connecting hole 211. This configuration simplifies the structure of the mounting assembly 200 and reduces costs. Please refer to the appendix. Figure 6 Both the mounting section 221 and the positioning section 222 are cylindrical, and the diameter of the positioning section 222 is smaller than the diameter of the mounting section 221. The stepped hole includes a first hole section 2232 and a second hole section 2233 connected together. The first hole section 2232 is located in the mounting section 221, and the end of the second hole section 2233 opposite to the first hole section 2232 passes through the positioning section 222.
[0037] In some embodiments of this application, the connecting plate 210 is provided with a fourth connecting hole 212, and the bell body 100 is provided with a fifth connecting hole. The second connector passes through the fourth connecting hole 212 and the fifth connecting hole to fix the connecting plate 210 and the bell body 100 together. This arrangement simplifies the connection structure between the bell body 100 and the connecting plate 210.
[0038] Preferably, the second connector is a second rivet 240, the fourth connecting hole 212 penetrates the connecting plate 210, and the fifth connecting hole penetrates the bell body 100 along the thickness direction of the bell body 100. Specifically, the second rivet 240 includes a second rivet 240 head and a second rivet 240 post. The second rivet 240 head abuts against the side of the connecting plate 210 away from the bell body 100, and the second rivet 240 post passes through the fourth connecting hole 212 and the fifth connecting hole, with its end pressed against the side of the bell body 100 away from the connecting plate 210. Alternatively, the second rivet 240 head abuts against the side of the bell body 100 away from the connecting plate 210, and the second rivet 240 post passes through the fifth connecting hole and the fourth connecting hole 212, with its end pressed against the side of the connecting plate 210 away from the bell body 100.
[0039] Of course, in other embodiments, the second connector is not limited to the above. For example, the second connector can also be a second bolt. In this case, the fourth connecting hole 212 is a threaded hole and the fifth connecting hole penetrates the bell body 100. The second bolt passes through the fifth connecting hole and is screwed into the fourth connecting hole 212. Alternatively, the fifth connecting hole is a threaded hole and the fourth connecting hole 212 penetrates the connecting plate 210. The second bolt passes through the fourth connecting hole 212 in sequence and is screwed into the fifth connecting hole.
[0040] This application embodiment also provides a weight-adjustable dumbbell, including the aforementioned base, grip bar, and two sets of counterweight plates. Both ends of the base are provided with two sets of support grooves, each corresponding to one of the two sets of counterweight plates. Each set of counterweight plates includes multiple plates as described above, and the support groove sets include multiple spaced-apart support grooves, with each counterweight plate inserted into one of the grooves. Both ends of the grip bar have a bar, and each bar has a rotatable hanging plate assembly. The hanging plate assembly includes multiple hanging plates, each corresponding to one of the counterweight plates. Each hanging plate has a tooth, and the tooth positions on each hanging plate are different. When the grip bar is placed on the base, the bar enters the bar receiving groove 110 through an opening, and each hanging plate is located on one side of its corresponding counterweight plate. When the mounting plate rotates to the mounting position, the mounting teeth of the mounting plate press against the mounting post 220 of the corresponding counterweight bell on the side away from the bell rod receiving groove 110. At this time, the bell rod and the bell rod receiving groove 110 also abut against each other, so that the counterweight bell is fixedly mounted on the grip bar.
