[0023] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Please refer to the attached document. Figure 1-4This application provides a hanging plate structure, including a hanging plate 100 and a reinforcing member 200, the reinforcing member 200 being used to increase the structural strength of the hanging plate 100. The hanging plate 100 includes a main body 110 and a hanging tooth portion 120. The main body 110 has a through mounting hole 101 for a dumbbell hanging rod to pass through. The hanging tooth portion 120 is located on one side of the main body 110 along the axial direction of the mounting hole 101, and is used to engage with the attachment portion of a counterweight to hang the counterweight on the hanging rod. The reinforcing member 200 is located in the main body 110, with a portion of the reinforcing member 200 situated within the hanging tooth portion 120, wherein the hardness of the reinforcing member 200 is greater than the hardness of the hanging plate 100.

[0026] In this embodiment, since the strength of the reinforcing member 200 is greater than that of the hanging plate 100, the reinforcing member 200 is disposed in the main body 110 of the hanging plate and part of the reinforcing member 200 is located in the hanging tooth part 120. This allows the reinforcing member 200 to structurally strengthen the hanging plate 100, especially to significantly strengthen the strength of the hanging tooth part 120 in the hanging plate 100 and the part of the hanging tooth part 120 connected to the main body 110 of the hanging plate. This effectively avoids the situation of the hanging tooth part 120 breaking, extends the service life of the dumbbell, and improves the user experience.

[0027] Preferably, the hanging plate 100 is made of plastic, such as, but not limited to, nylon. Preferably, the reinforcing member 200 is made of metal, such as, but not limited to, iron plate, galvanized plate, etc. Of course, the material of the reinforcing member 200 is not limited to metal; for example, it can also be made of plastic with a higher hardness than the hanging plate 100.

[0028] The position of the hanging tooth portion 120 on one side of the hanging plate main body 110 is not specifically limited, as long as there is a gap between the hanging tooth portion 120 and the mounting hole 101 for the hanging part on the counterweight bell plate to pass through. Preferably, the hanging tooth portion 120 is located near the outer edge of the hanging plate main body 110, which helps to achieve a miniaturized design of the hanging plate structure and reduce the cost of the hanging plate structure.

[0029] The number of mounting teeth 120 can be one or more. When there are multiple mounting teeth 120, they are arranged at circumferential intervals along the mounting hole 101. There can be multiple reinforcing members 200, each corresponding to one of the mounting teeth 120, with each reinforcing member 200 partially located within its corresponding mounting tooth 120. The multiple reinforcing members 200 can be arranged independently or connected to form a single integrated structure.

[0030] Please refer to the appendix. Figure 1Preferably, the main body 110 of the hanging plate is disc-shaped. The mounting hole 101 is located in the middle of the main body of the hanging plate 110, and its axis is parallel to the thickness direction of the main body 110. The hanging tooth part 120 is located outside the mounting hole 101. A cylindrical linkage part 130 is provided on one side of the main body 110, and the linkage part 130 and the hanging tooth part 120 are located on the same side of the main body 110. The mounting hole 101 passes through the linkage part 130. The end face of the linkage part 130 is provided with an anti-rotation protrusion 131. The side of the main body 110 away from the hanging tooth part 120 is provided with an anti-rotation groove 112. The anti-rotation protrusion 131 in the hanging plate structure is inserted into the anti-rotation groove 112 in another adjacent hanging plate structure to form an anti-rotation fit, so as to realize the linkage rotation between the two adjacent hanging plate structures.

[0031] In some embodiments of this application, the mounting plate 100 is an injection-molded part, meaning that the mounting plate 100 is formed by injection molding, and the mounting plate 100 is connected to the reinforcing member 200 during injection molding. This arrangement not only makes the production efficiency of the mounting plate structure high, but also ensures high bonding strength between the mounting plate 100 and the reinforcing member 200.

[0032] Of course, in other embodiments, the reinforcing member 200 and the hanging plate 100 can be fixedly connected together by means of adhesive bonding, screwing, etc.

[0033] In some embodiments of this application, the reinforcing member 200 includes a main reinforcing portion 210 and a toothed reinforcing portion 220. The main reinforcing portion 210 is disposed on the main body portion 110 of the mounting plate, and the toothed reinforcing portion 220 is disposed on one side of the main reinforcing portion 210 along the axial direction of the mounting hole 101 and located within the toothed portion 120. The main reinforcing portion 210 has an annular structure and surrounds the mounting hole 101. This arrangement expands the reinforcing position of the reinforcing member 200 on the mounting plate 100, thereby improving the reinforcing effect of the reinforcing member 200 on the mounting plate 100.

[0034] When there are multiple toothed parts 120, there are also multiple toothed reinforcing parts 220, which are spaced apart circumferentially along the main body reinforcing part 210. The multiple toothed reinforcing parts 220 are located one-to-one in the multiple toothed parts 120.

[0035] In some embodiments of this application, the main body reinforcement 210 is provided with weight reduction holes 211 to reduce the weight of the reinforcement 200, thereby reducing the weight impact of the reinforcement 200 on the hanging plate structure.

[0036] There may be one or more weight-reducing holes 211. When there are multiple weight-reducing holes 211, the multiple weight-reducing holes 211 are spaced apart along the direction surrounding the mounting hole 101.

[0037] The main body reinforcement 210 and the tooth reinforcement 220 can be fixedly connected together by a connector; or the main body reinforcement 210 and the tooth reinforcement 220 can be integrally formed and connected, that is, the reinforcement 200 is an integrally formed structure, which not only improves the production efficiency of the reinforcement 200, but also makes the overall performance of the reinforcement 200 better.

[0038] In some embodiments of this application, the main body 110 of the hanging plate is provided with a filling part 111, which extends into the weight reduction hole 211 and contacts the hole wall surface of the weight reduction hole 211. The filling part 111 can limit the reinforcing member 200 and prevent relative rotation between the reinforcing member 200 and the hanging plate 100.

[0039] When the mounting plate 100 and the reinforcing member 200 are injection molded together, the injection molding material used to prepare the mounting plate 100 fills the weight-reducing hole 211 to form a filling part 111. The filling part 111 and the weight-reducing hole 211 are bonded to each other, increasing the bonding area between the mounting plate 100 and the reinforcing member, thereby improving the connection strength between the two. Preferably, the end face of the filling part 111 is recessed with a pressure groove to make the bond between the filling part 111 and the weight-reducing hole 211 more solid.

[0040] In some embodiments of this application, the main body reinforcement 210 includes a first side facing away from the tooth reinforcement 220, and the main body 110 of the hanging plate is provided with a covering portion 222 on the side facing away from the tooth 120. The covering portion 222 includes the outer peripheral surface of the main body reinforcement 210 and at least a portion of the first side. The covering portion 222 increases the bonding area between the hanging plate 100 and the reinforcement 200, thereby improving the connection strength between the two and preventing separation between them.

[0041] Please refer to the attached document. Figure 1 Preferably, the covering portion 222 has a first side surface, and the edge of the covering portion 222 has a distance from the weight reduction hole 211.

[0042] In some embodiments of this application, the end of the toothed reinforcement 220 away from the main reinforcement 210 is provided with a weight reduction groove 221. The weight reduction groove 221 can reduce the weight of the reinforcement 200 and also increase the bonding strength between the reinforcement 200 and the hanging plate 100.

[0043] This application also provides a weight-adjustable dumbbell, including the hanging plate structure described above.
