Description

Technical Field

[0001] The utility model belongs to the field of fitness equipment, in particular to a hanging boxing device. Background Art

[0002] Existing boxing devices are usually set up in gyms, which include a support frame that occupies a certain space and plays a supporting role, and a boxing sandbag hung on the support frame, or the boxing sandbag is hung by a rope or chain nailed to the wall, and the user exercises by hitting the boxing sandbag. The boxing sandbag is usually filled with sand, and boxing gloves need to be worn to hit it to avoid hand injuries during fitness training. However, the existing boxing device occupies a large area and the boxing sandbag is hard in texture. It is only suitable for people with special training needs, and is not suitable for people's daily exercise. In particular, children, women and the elderly with weak hitting ability often choose other gentle exercise methods. The prior art proposes a plastic boxing bag in the hope of improving the above situation. However, since it is formed in one piece with the same material, the hardness of the hanging part and the striking part can only be kept consistent. If the boxing bag is made according to the hardness of the hanging part (the overall Shore hardness of the boxing bag is greater than or equal to 50), the striking part is harder and easy to hurt the hand, and it cannot meet the requirement of direct hand striking; if the boxing bag is made according to the hardness of the bare-hand striking part (the overall Shore hardness of the boxing bag is less than 50), it will cause the problem of insufficient load-bearing capacity of the hanging part, easy cracking of the boxing bag, and thus unusable. Therefore, the existing plastic boxing bags formed in one piece with the same material cannot meet the needs of daily exercise. In addition, the support frame used by the existing boxing device occupies a large space and is inconvenient to store, or the boxing device needs to be nailed to the wall for hanging and use, which damages the wall and is not convenient for disassembly and assembly. Therefore, the existing boxing device is limited in use and is not suitable for home use. Utility Model Content

DETAILED DESCRIPTION

[0027] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the utility model, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0028] Example 1

[0029] In this embodiment, Figures 1 to 3As shown, a hanging boxing device is provided, comprising a boxing bag 1 that can be hung for use and a telescopic beam 2 for supporting. The boxing bag 1 is connected to the telescopic beam 2 through a flexible and length-adjustable flexible member 3. The telescopic beam 2 can be set on the inner side of a door frame or between two oppositely arranged walls, which neither affects the opening and closing of the door and walking nor damages the door frame or the wall. The length of the flexible member is adjustable, which can meet the training requirements of people of different heights and different parts of the body. The boxing bag 1 comprises a hanging part 11, a filling part 12 and a material injection port. The hanging part 11 can be suspended and stressed, and is a hard plastic part. In this embodiment, the hanging part 11 is made of PVC powder and plasticizer by heating. The Shore hardness of this part is at least 50, and its texture is slightly hard, and its strength can meet the requirements of hanging use; the filling part 12 can be filled with fluid, and is a soft plastic part. In this embodiment, the filling part 12 is made of PVC powder and plasticizer by heating. The Shore hardness of the filling part is reduced by increasing the proportion of plasticizer, and the Shore hardness is between 25 and 50. The texture is soft, and the user does not need to wear boxing gloves for protection when hitting the filling part, and can directly hit with bare hands, which reduces the use requirements and expands the use objects; the material injection port is arranged on the hanging part 11, and the filling part 12 can be filled with fluid through the material injection port. When not in use, the fluid can be discharged and the boxing bag can be folded. Therefore, the hanging boxing device of the present application is convenient for disassembly and storage, occupies little space, and is suitable for home use. The end of the filling part 12 extends toward the hanging part 11 and is closely connected to the hanging part 11, and an overlap section 13 is formed between the filling part 12 and the hanging part 11. The overlap section 13 includes an inner layer and an outer layer. The inner layer is formed by the end of the filling part 12 being attached to the inner wall of the hanging part 11 by hot-melt, and the hanging part 11 forms the outer layer. The filling part 12 is attached to the inner wall of the hanging part 11 by hot-melt, and the contact area between the two is large, forming a relatively firm connection.

[0030] The end of the telescopic beam 2 has a flexible resistance surface 21. By applying a resistance force, the telescopic beam can be set on the inner side of the door frame without affecting the opening and closing of the door and walking. It can be stored vertically and occupies a small space. The flexible resistance surface 21 is not easy to damage the surface of the door frame, and can increase the resistance friction, so it is not easy to fall off after assembly. The hanging part 11 is located at the top of the filling part 12.

The positioning member 7 includes a hook-shaped portion 71 with a notch and a swinging portion 72 swingably arranged at the notch. The swinging portion 72 has an elastic member 721 at one end and a threaded segment 722 at the other end. The elastic member 721 is hinged at the notch, and the threaded segment 722 is limited by the end of the hook-shaped portion 71, so that the swinging portion 72 can swing relative to the notch under the action of an external force, and abut against and limit the hook-shaped portion 71 under the elastic force provided by the elastic member 721 when no external force is applied. The threaded segment 722 is used in conjunction with a threaded sleeve 73, and the threaded sleeve 73 can cover the matching position between the threaded segment 722 and the hook-shaped portion 71. The flexible part can be a rope, chain or other part that has a certain flexibility and can bear a certain weight. The length can be fixed by setting a positioning part. The positioning part has a threaded sleeve 73, which cooperates with the threaded section 722 to cover the matching part between the threaded section 722 and the hook-shaped part 71 to prevent the positioning part 7 from being accidentally opened and causing danger.

[0032] The hanging portion 11 has a connecting hole 111 so that the flexible member 3 can pass through indirectly.
