[0002] Punching bags, also known as sandbags, are a type of training equipment used in combat sports, primarily for striking and strength training. A sandbag isn't literally a bag filled with sand; if it were, it would be too hard to hit. Sandbags are typically made from microfiber leather, PU leather, canvas, or Oxford cloth. A cushioning layer of EVA or plastic foam is placed between the interior and the filling. Finished sandbags are often filled with rags. Sandbags come in a variety of shapes and sizes, depending on the training focus, fighting style, and other factors. The most common traditional sandbag is cylindrical, but other shapes include bananas (relatively elongated cylinders), balls, teardrops, pears, big heads, and bowling balls.
[0003] However, the weight of the traditional Sanda sandbag is fixed and cannot be adjusted. For example, a standing Sanda sandbag cannot meet the sports requirements of different users for the weight of the sandbag. Moreover, the standing Sanda sandbag can only be used while standing and cannot be used while hanging, so its scope of application is narrow. Summary of the Invention

DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0023] See also Figure 1-4 The present invention provides a technical solution: a hanging standing two-in-one multifunctional Sanda sandbag, comprising a base 1, a support member 2 detachably fixedly connected to the top of the base 1, and a sandbag 3 mounted on the support member 2, wherein the top of the sandbag 3 has a hanging connection portion 31;
[0024] A lifting device 4 is provided in the base 1, and a load-bearing member 9 is detachably fixedly connected to the top of the lifting device 4. Several heavy objects 5 are installed on the load-bearing member 9. The support member 2 is hollow inside, and the lifting device 4 can drive the load-bearing member 9 to make a linear motion in the up and down directions inside the support member 2.
[0025] In this embodiment, the lifting device 4 is arranged inside the base 1, and the lifting device 4 passes through the bottom of the base 1 and the support 2, and one end of the lifting device 4 extends into the support 2.
[0026] The device 4 drives the load-bearing member 9 to make a linear motion in the vertical direction inside the support member 2, changing the relative position of the load-bearing member 9 inside the support member 2. Because a number of heavy objects 5 are installed on the load-bearing member 9, when more heavy objects 5 enter the space surrounded by the sandbag 3, the center of gravity of the sandbag 3 moves upward, thereby increasing the weight of the sandbag 3, which can meet different usage requirements for the weight of the sandbag 3. In addition, the sandbag can also be hung for use. First, release the detachable connection between the support member 2 and the base 1, and then release the detachable connection between the lifting device 4 and the load-bearing member 9. The heavy object 5 falls to the bottom of the support member 2 with the load-bearing member 9. Finally, the sandbag 3 is locked and hung for use by using the hanging connection part 31. When the user wants to use the sandbag while standing, install the support member 2 and the base 1, install the lifting device 4 and the load-bearing member, and install them as shown below. Figure 1As shown, the sandbag can be freely switched between standing use and hanging use.
[0027] Furthermore, the base 1 includes a main body 11 for installing the lifting device 4 and a top block 12 fixedly connected to the top of the main body 11. The load-bearing member 9 includes a steel pipe 21 and an insert block 22 fixedly connected to the bottom of the steel pipe 21. A slot 13 adapted to the insert block 22 is provided on the upper surface of the top block 12, and the insert block 22 is inserted into the slot 13.
[0028] In this embodiment, when installing the support member 2 and the base 1, the insert block 22 is inserted into the slot 13. The insert block 22 and the slot 13 are preferably interference fit to enhance the stability of the support member 2 and the base 1 after installation and prevent them from falling apart.
[0029] Furthermore, bolts 8 are threadedly passed through both side walls of the top block 12 , and one end of each bolt 8 abuts against the side wall of the insert block 22 .
[0030] In this embodiment, in order to improve the stability of the support member 2 and the base 1 after installation, the bolt 8 is rotated so that one end of the bolt 8 abuts against the side wall of the insert block 22, which can press the insert block 22 to prevent the insert block 22 from falling out of the slot 13.
[0031] Furthermore, the lifting device 4 is a hydraulic cylinder, a pneumatic cylinder or an electric push rod.
[0032] In this embodiment, the hydraulic cylinder or the pneumatic cylinder or the electric push rod are all commonly used devices in the prior art, and their output shafts are detachably fixed to the bottom of the load-bearing member 9, and their output shafts all pass through the top block 12 and the insert block 22.
[0033] Furthermore, the weight 5 is a barbell plate mounted on the load-bearing member 9, the bottom of the load-bearing member 9 is provided with an external thread, the output end of the lifting device 4 has a concave hole and the inner wall of the concave hole is provided with an internal thread that matches the external thread.
[0034] Thread.
[0035] In this embodiment, the barbell plates are sports equipment that are easy to obtain, and the barbell plates have different weight grades, which makes it easy to select barbell plates of different weights and install them on the load-bearing member 9. The lifting device 4 is detachably fixed to the load-bearing member 9 through the cooperation between the external thread and the internal thread.
[0036] Furthermore, a plurality of buffer connection devices 7 are provided between the sandbag 3 and the base 1 .
[0037] In this embodiment, the buffer connection device 7 is used to absorb the rebound force generated after the sandbag 3 is hit. The buffer connection device 7 can be relatively arranged into two, respectively located on both sides of the sandbag 3. The buffer connection device 7 can also be arranged in a circular, uniform, and equidistant manner on the outer periphery of the base 1.
[0038] Furthermore, the buffer connection device 7 is an elastic rope 71 , one end of which is fixedly connected to the sandbag 3 , and the other end of which is fixedly connected to the base 1 .
[0039] In this embodiment, the elastic rope 71 can absorb or generate elastic force. After the sandbag 3 is hit, the elastic rope 71 is tightened to generate elastic force to prevent the sandbag 3 from excessively deflecting. During the rebound of the sandbag 3, the elastic rope 71 arranged opposite to the first elastic rope 71 is tightened to generate elastic force to prevent the sandbag 3 from excessively deflecting. Under the repeated action of the two oppositely arranged elastic ropes 71, the rebound force of the sandbag 3 can be gradually absorbed, thereby preventing the sandbag 3 from rebounding too much and causing harm to people.
[0040] Furthermore, the buffer connection device 7 is a spring 72 , one end of which is fixedly connected to the sandbag 3 , and the other end of which is fixedly connected to the base 1 .
[0041] In this embodiment, the working principle of the spring 72 is the same as that of the elastic cord 71 described above.
[0042] Furthermore, the buffer connection device 7 is a telescopic member 73 , one end of which is hinged to the sandbag 3 , and the other end of which is hinged to the base 1 .
[0043] In this embodiment, the telescopic member 73 is an existing telescopic slide rod or cylinder. When the sandbag 3 compresses the telescopic member 73, the length of the telescopic member 73 itself becomes shorter. When the sandbag 3 stretches the telescopic member 73, the length of the telescopic member 73 itself becomes longer, thereby absorbing the rebound force of the sandbag 3 and preventing the sandbag 3 from rebounding too much and causing harm to people.
[0044] Furthermore, a non-slip rubber pad 6 is provided on the bottom surface of the base 1 .
[0045] In this embodiment, a non-slip rubber pad with a high anti-slip coefficient is provided on the bottom surface of the base 1 to increase the bottom
[0046] The friction between the seat 1 and the contact object makes the base difficult to slide.
[0047] The working principle and usage process of the present invention: After the present invention is installed, the lifting device 4 is arranged inside the base 1, and the lifting device 4 passes through the bottom of the base 1 and the support 2, and one end of the lifting device 4 extends into the support 2. The lifting device 4 drives the load-bearing member 9 to make a linear motion in the up and down directions inside the support 2, changing the relative position of the load-bearing member 9 inside the support 2. Because a number of heavy objects 5 are installed on the load-bearing member 9, when more heavy objects 5 enter the space wrapped by the sandbag 3, the center of gravity of the sandbag 3 moves up, thereby increasing the weight of the sandbag 3, which can meet different usage requirements for the weight of the sandbag 3. The sandbag can also be hung for use. First, the detachable connection between the support 2 and the base 1 is released, and then the detachable connection between the lifting device 4 and the load-bearing member 9 is released. The heavy object 5 falls to the bottom of the support 2 with the load-bearing member 9. Finally, the sandbag 3 is locked and hung for use by using the hanging connection part 31. When the user wants to use the sandbag standing, the support 2 and the base 1 are installed, and the lifting device 4 and the load-bearing member are installed, so that the sandbag can be freely switched between standing use and hanging use.
[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
