[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0024] Please see Figures 1-5 As shown, the purpose of this embodiment is to provide a multifunctional fitness sandbag, including a support frame 1. A sandbag 2 is suspended and fixed at one end of the support frame 1. The bottom of the sandbag 2 has a slot, and a first support cylinder 6 is fixedly installed in the slot. The bottom of the first support cylinder 6 is threadedly connected to a support device 9 for adjusting the height of the sandbag 2. The sandbag 2 has column slots on both sides, and a second support cylinder 7 is fixedly installed in the column slot. An auxiliary device 10 is fixedly connected to one end of the second support cylinder 7. The auxiliary device 10 is used for auxiliary training and mainly to increase the versatility of the functions of the sandbag 2. Several connecting straps 21 are fixedly connected to the top of the sandbag 2, and one end of each connecting strap 21 is fixedly connected to the support frame 1.
[0025] A plurality of connecting ears 62 are fixedly provided on the side wall of the first support cylinder 6. The connecting ears 62 are provided with dense connecting holes. The first support cylinder 6 is sewn to the inner wall of the hole groove through the connecting ears 62. The first support cylinder 6 is a rigid support and will not be deformed due to the compression of the filling material in the sandbag 2.
[0026] The support device 9 includes a support rod 31. The bottom of the first support cylinder 6 has a column hole 61. One end of the support rod 31 is threaded into the column hole 61, and the other end of the support rod 31 is threaded to a support seat 3. The position of the support rod 31 on the support seat 3 and the sandbag 2 can be adjusted by the threaded installation, thereby adjusting the height of the sandbag 2 to adjust the appropriate striking height.
[0027] The auxiliary device 10 includes a connecting rod 5, one end of which is fixed with an auxiliary bag 4. The connecting rod 5 is threadedly installed inside the second support cylinder 7. The connection method between the second support cylinder 7 and the sandbag 2 is the same as that between the first support cylinder 6 and the sandbag 2.
[0028] The top of the sandbag 2 has a straight groove, and a third support cylinder 8 is fixedly installed in the straight groove. A supplementary bag 22 is threadedly installed in the third support cylinder 8. The connection between the third support cylinder 8 and the sandbag 2 is the same as that between the first support cylinder 6 and the installation end of the supplementary bag 22 is a rigid support cylinder. The other end of the supplementary bag 22 has a larger diameter and can be exposed outside the sandbag 2. A supplementary bag 22 of appropriate weight can be added according to the weight of the sandbag 2 to improve the training effect.
[0029] The diameter of the first support cylinder 6 is smaller than the diameter of the third support cylinder 8, and the diameter of the third support cylinder 8 is smaller than the radius of the sandbag 2.
[0030] The height of the first support cylinder 6 is greater than the height of the third support cylinder 8, and the height of the first support cylinder 6 is 1 / 4 of the height of the sandbag 2. The diameter and length of the second support cylinder 7 are both smaller, and the second support cylinder 7 is located below the third support cylinder 8.
[0031] When the sandbag 2 is fixedly connected to the support frame 1, it is called hanging strike; when the sandbag 2 is threadedly installed on the support base 3, it is called fixed strike. During hanging strike, the sandbag 2 swings, and the auxiliary bag 4 swings accordingly, and at a faster speed. The user strikes the sandbag 2 and then strikes the auxiliary bag 4, which can train the user's reaction speed and improve the training accuracy. In addition, the two connection methods of the sandbag 2 are convenient to switch and assemble, which is beneficial to the training efficiency.
[0032] In practical use, when hitting at a fixed time, the support rod 31 is threaded onto the support base 3, and one end of the support rod 31 is threaded into the column hole 61 at the bottom of the first support cylinder 6. Then, the height of the sandbag 2 is adjusted according to the user's hitting height. When hitting from a height, the connecting strap 21 at the top of the sandbag 2 is wrapped and fixedly connected to the support frame 1, and the connecting rod 5 is threaded into the second support cylinder 7. Therefore, the auxiliary bag 4 is located on both sides of the sandbag 2. When hitting the sandbag 2, the sandbag 2 swings, and the auxiliary bag 4 swings accordingly. After the user hits the sandbag 2, he hits the auxiliary bag 4. This can be repeated to train the user's reaction speed and improve training ability. During the training process, the user can selectively add supplementary bags 22 of different weights according to his own training ability. One end of the supplementary bag 22 is threaded into the third support cylinder 8.
[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
