[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model proposes an adjustable breathing dumbbell, including a training device body 1, see reference. Figure 1 , 2 The training device body 1 has a tubular cavity 11 inside, and a counterweight 12 is slidably connected inside the tubular cavity 11. One end of the tubular cavity 11 has an air inlet 131, and an exhalation tube 14 is connected to the air inlet 131.

[0028] Adjustment components, see Figure 3The adjustment assembly includes a rotatably connected sealing seat 2 and an adjustment cover 3. The sealing seat 2 is fixed to the other end of the tubular cavity 11, and the sealing seat 2 is provided with an air outlet 212 that communicates with the tubular cavity 11. The adjustment cover 3 is provided with an adjustment hole 31. This product adjusts the airflow resistance inside the tubular cavity 11 by changing the diameter of the connecting hole between the adjustment hole 31 and the air outlet 212. With the number of counterweights 12 remaining unchanged, the user can adjust the blowing resistance by rotating the adjustment cover 3 without disassembling the product, making it more convenient to use.

[0029] Referring to 3 and 4, the sealing seat 2 is provided with a rotating groove 211, the adjusting cover 3 is rotatably connected to the rotating groove 211, and the air outlet 212 is provided on the bottom surface of the rotating groove 211. Preferably, the bottom surface of the adjusting cover 3 is in close contact with the rotating groove 211.

[0030] See Figure 3 The rotating groove 211 has a first clearance hole 216 on its side wall, and the adjusting cover 3 has an insertion groove 32 on its side wall. A control block 33 is inserted into the insertion groove 32. The user can move the control block 33 to slide it within the range of the first clearance hole 216 to achieve the rotation of the adjusting cover 3.

[0031] See Figure 2 , 3 The sealing seat 2 includes a positioning cover 21 and a connecting cover 22. The connecting cover 22 has a connecting groove 221 inside. The positioning cover 21 is fixed in the connecting groove 221. The connecting cover 22 is fixed to the other end of the tubular cavity 11. The rotating groove 211 is provided inside the positioning cover 21. The connecting cover 22 has a second clearance hole 224 communicating with the first clearance hole 216. The connecting cover 22 may be provided with an internal thread. The outer wall of the tubular cavity 11 may be provided with an external thread.

In the combined state, the sealing ring 23 abuts against the end of the tubular cavity 11, thereby improving the sealing performance between the sealing seat 2 and the tubular cavity 11, ensuring that the air in the tubular cavity 11 can only flow out through the air outlet 212. The annular sealing boss 231 is embedded in the air outlet 212, and the top surface of the annular sealing boss 231 fits against the adjusting cover 3. The annular sealing boss 231 can ensure that the air flowing out through the air outlet 212 can only flow out from the connecting part between the adjusting hole 31 and the air outlet 212. The setting of the sealing ring 23 can improve the sealing effect of the air outlet path of this product, so as to ensure the precise correspondence between the rotation of the adjusting cover 3 and the change of air blowing resistance.

[0033] See Figure 4 The bottom surface of the positioning cover 21 is provided with a positioning boss 213, and the sealing ring 23 is provided with a positioning hole 232. The positioning boss 213 and the positioning hole 232 are engaged to fix the position of the connecting cover 22 and the sealing ring 23.

[0034] See Figure 3 The rotating groove 211 has a plurality of positioning slots 217 on its side wall, and the adjusting cover 3 has positioning protrusions 34 on its side wall. When the adjusting cover 3 rotates, the positioning protrusions 34 engage with the positioning slots 217 at different positions, thereby achieving the positioning effect of the adjusting cover 3. The annular sealing boss 231 has a limiting groove 233, and the air outlet 212 is engaged in the limiting groove 233.

[0035] See Figure 4 The side wall of the connecting groove 221 is provided with a plurality of guide grooves 222 and snap-fit ​​protrusions 223. The positioning cover 21 is provided with a plurality of guide protrusions 214 and snap-fit ​​grooves 215. The circumferential position of the positioning cover 21 and the connecting cover 22 is fixed by the snap-fit ​​cooperation between the guide protrusions 214 and the guide grooves 222. The positioning cover 21 is fixed in the connecting groove 221 by the snap-fit ​​connection between the snap-fit ​​protrusions 223 and the snap-fit ​​grooves 215.

[0036] See Figure 2 One end of the tubular cavity 11 is provided with a sealing plug 13, the air inlet 131 is provided on the sealing plug 13, and the exhalation tube 14 is connected to the sealing plug 13.
