Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-5 A fitness cannon barrel that is easy to assemble includes a fitness cannon barrel body 1. Removable counterweights 2 are installed at both ends of the fitness cannon barrel body 1. Adjustment discs 3 are rotatably mounted on each counterweight 2. Adjustment components 31 are fixedly mounted on each adjustment disc 3. Adjustment grooves 12 are adapted to fit the adjustment components 31 on the inner wall of the fitness cannon barrel body 1. The adjustment discs 3 are fixedly connected to knobs 33 via fixing posts 32. Locking posts 41 are movably mounted on each knob 33, and locking grooves 23 are adapted to fit the locking posts 41 on each counterweight 2.

[0016] The counterweight 2 has multiple mounting parts 21 fixedly installed on its outer wall. The two ends of the fitness cannon body 1 are fitted with mounting slots 11 corresponding to the mounting parts 21, and the adjustment slots 12 are connected to the mounting slots 11. This fit between the mounting parts 21 and the mounting slots 11 improves the installation stability of the counterweight 2.

[0017] Each counterweight 2 has a through hole 22 in its center, and each fixing post 32 is adapted to rotate within the through hole 22. This allows the adjusting disc 3 and the knob 33 to rotate at both ends of the counterweight 2, so that the user can rotate the adjusting disc 3 using the knob 33.

[0018] Each knob 33 has an inwardly opening spring cavity 35 on its outer side, and a spring 351 is installed outwardly within each spring cavity 35. The other end of each spring 351 is connected to a pull plate 4, and multiple locking pins 41 are fixedly mounted on the pull plate 4. The springs 351 pull the locking pins 41 inward, allowing them to be stably locked within the locking groove 23. It is worth noting that the springs 351 are existing shock-absorbing high-strength springs to ensure the stability of the locking pins 41 during locking and prevent them from falling off due to vibration during use of the fitness cannon barrel 1. The specific structure and operation of the shock-absorbing high-strength springs are existing technologies and are not related to the technical problem of easily disassembling and assembling the weight block 2 that needs to be addressed in this technical solution; therefore, they will not be elaborated upon further.

[0019] Among them, the knob 33 is provided with a through cavity 34 corresponding to the locking post 41. When the mounting part 21 and the adjusting part 31 are misaligned, the through cavity 34 is aligned with the locking groove 23.

[0020] In this embodiment, when the user needs to install the counterweight 2 on the fitness gun body 1, they only need to ensure that the mounting part 21 on the counterweight 2 is properly aligned with the adjusting part 31 on the adjusting plate 3, and then align the mounting part 21 with the mounting groove 11, so that the counterweight 2 can be inserted into the fitness gun body 1. When the mounting part 21 is fully inserted into the mounting groove 11, the adjusting part 31 is also properly inserted into the adjusting groove 12.

[0021] The user then simply pulls the pull plate 4 outwards, which causes the locking pin 41 to move outwards synchronously, thus releasing the locking pin 41 from the locking groove 23 and stretching the spring 351. The user can then rotate the knob 33, which causes the fixed pin 32, adjusting plate 3, and adjusting component 31 to rotate synchronously, thus locking the adjusting component 31 deep within the adjusting groove 12. This interlocking action between the adjusting component 31 and the adjusting groove 12 allows for the installation of the counterweight 2.

[0022] When the adjusting member 31 is locked at the deepest part of the adjusting groove 12, the locking pin 41 is once again adapted and aligned with the locking groove 23. At this time, the user only needs to loosen the pull plate 4, and the pull plate 4 and the locking pin 41 can automatically move inward and reset by the elastic force of the spring 351, so that the locking pin 41 can be locked into the locking groove 23 again to prevent the adjusting plate 3 from rotating.

[0023] Furthermore, when the user needs to disassemble the counterweight 2, simply pull the pull plate 4 outward again to release the locking pin 41 and the locking groove 23. Then, turn the knob 33 in the opposite direction to rotate the adjusting member 31 to align with the mounting member 21, thereby removing the counterweight 2.

[0024] Furthermore, the counterweight 2 in this application is provided with multiple weights, and users can install counterweights 2 of different weights at both ends of the fitness cannon body 1, as long as the weight at both ends is consistent.

[0025] Furthermore, the counterweight 2 has multiple locking grooves 23, which allows the locking pin 41 to be adapted and aligned with the locking groove 23 when the adjusting member 31 is aligned with the mounting member 21, or when the adjusting member 31 is located at the deepest part of the adjusting groove 12.

[0026] In this utility model, by installing counterweights 2 of different weights at both ends of the fitness cannon body 1, the weight of the fitness cannon body 1 can be adjusted. Through the fitting and locking between the adjusting component 31 and the adjusting groove 12, and with the locking pin 41, the counterweights 2 can be quickly assembled at both ends of the fitness cannon body 1. This method of assembling and disassembling the counterweights 2 is simple and convenient, facilitating personalized weight adjustment needs for different groups. The above description is only a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
