[0002] With the popularization of fitness activities, dumbbells and kettlebells are widely used in home and commercial gyms as basic strength training equipment. Conventional dumbbells and kettlebells usually adopt a fixed structure or a simple adjustable weight design, but their functions are limited and cannot meet the diverse training needs of users. That is, when users conduct comprehensive training, they need to purchase dumbbells and kettlebells at the same time, which not only takes up space and is not easy to store, but also increases the purchase cost.

[0003] Therefore, in the training device for freely combinable dumbbells, barbells, and kettlebells disclosed in application number CN2023208081641, when the device is used as a dumbbell, the left and right weight bases are an integral structure, and the weight connectors at both ends of the dumbbell bar cooperate with the left and right weight assemblies through locking pins and locking holes to form an adjustable weight dumbbell; when the device is used as a kettlebell, the left and right weight bases are separate or hinged structures, and the weight connector of the kettlebell handle cooperates with one of the weight assemblies through locking pins and locking holes to form an adjustable weight kettlebell. In this technical solution, the locking holes are located on the weight shafts. To form an adjustable weight dumbbell, the left and right weight bases need to be separated first, and the left and right weight shafts need to be inserted into the weight connectors of the dumbbell bar respectively before the left and right weight bases are combined, or the left and right weight assemblies need to be removed, and the left and right weight assemblies and dumbbell bars need to be combined to form an adjustable weight dumbbell before being put back on the weight bases.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] Example 1: As Figures 1 to 6 As shown, a combination training device includes a base 1, two weight assemblies 2, a dumbbell bar 3 and a kettlebell handle 4. The two weight assemblies 2 are placed on the base 1 and distributed from left to right. The weight assemblies 2 are provided with connection holes 211.

[0037] In this embodiment, the dumbbell bar 3 is provided with a first connecting seat 51 at both ends for longitudinal sliding engagement with the counterweight assembly 2. The first connecting seat 51 is provided with a mounting hole 511 communicating with the connecting hole 211. Two spindles 31 are provided inside the dumbbell bar 3, which are distributed left and right. The spindles 31 slide laterally with the dumbbell bar 3 and extend into the mounting hole 511 on the same side.

[0038] In this embodiment, the connecting end of the kettlebell handle 4 is provided with a second connecting seat 52 for longitudinal sliding cooperation with the counterweight assembly 2. The second connecting seat 52 is provided with a socket 521, a pin 522 and a first locking member 523. The socket 521 is connected to the connecting hole 211, the pin 522 passes through the socket 521, and the first locking member 523 is used to lock the pin 522.

[0039] When the trainer is used as a dumbbell, the first connecting seat 51 mates with the weight assembly 2, and the spindle 31 extends into the connecting hole 211 on the same side. When the trainer is used as a kettlebell, the second connecting seat 52 mates with the weight assembly 2, and the pin 522 extends into the connecting hole 211. When it is necessary to disassemble the dumbbell bar 3 or the kettlebell handle 4, the corresponding spindle 31 or pin 522 is removed from the weight assembly 2, and then the first connecting seat 51 or the second connecting seat 52 is separated from the weight assembly 2. The disassembly and assembly of the dumbbell bar 3 and the kettlebell handle 4 are relatively simple, and users can quickly switch this combination trainer to dumbbells or kettlebells, making it convenient to use.

The inner dumbbell plate 21a, the intermediate plates 21b, and the outer dumbbell plate 21c are provided with a first limiting groove 212 and a first embedding block 213 on both sides. Two adjacent counterweight plates 21 are engaged with each other through the first limiting groove 212 and the first embedding block 213. The first connecting seat 51 and the second connecting seat 52 are provided with a second limiting groove 53 and a second embedding block 54. The first limiting groove 212 on the side of the inner dumbbell plate 21a away from the intermediate plate 21b is used to engage with the second embedding block 54, and the first embedding block 213 on the side of the inner dumbbell plate 21a away from the intermediate plate 21b is used to engage with the second limiting groove 53. It should be noted that setting a limiting groove and an inserting block on the counterweight plate 21 is a conventional technical means in this field. The limiting groove and the inserting block cooperate to prevent lateral movement between adjacent counterweight plates 21. At the same time, the mandrel 31 passing through the connecting hole 211 or the pin 522 passing through the connecting hole 211 prevents the corresponding counterweight plate 21 from moving longitudinally, thus locking the counterweight plate 21. Furthermore, by setting a second limiting groove 53 and a second inserting block 54 on the first connecting seat 51 and the second connecting seat 52, when the mandrel 31 / pin 522 passes through the connecting hole 211, a lock is formed between the first connecting seat 51 / second connecting seat 52 and the counterweight plate 21. When the mandrel 31 / pin 522 disengages from the connecting hole 211, the user can move the dumbbell bar 3 / kettlebell handle 4 to separate the first connecting seat 51 / second connecting seat 52 from the counterweight plate 21, which is convenient for disassembly and assembly and easy to use.
