Description
Technical Field
The invention belongs to the technical field of sports equipment, and particularly relates to a sandbag with an adjustable swing amplitude.
Background
The sand bag mentioned above mainly refers to a pile-type sand bag, which is also called "pile-type sand bag". The sandbag is an indoor sports equipment with simple structure, small investment and wide application range, thus being popular among people. Technical information on sandbags is not well known in the published chinese patent literature, such as CN2346472Y (boxing sandbag), CN2452560Y (tumbler sandbag), CN201214007Y (three-in-one scaffold target with a suction cup base tumbler/sandbag/wooden stake), CN102258857A (wooden stake sandbag), CN102357298A (superposed sandbag), CN102397690A (wooden stake sandbag), CN102743851A (wooden stake sandbag), CN104162265A (building block pile structure of boxing sandbag) and CN104162264A (pile structure of boxing sandbag), to name a few.
Not limited to the above-mentioned patent solutions, in common: the sandbag will swing but will not fall over (also called "toppling") and a lodging situation is undesirable when struck. The sand bag is prevented from falling down, so that accidents can be prevented; secondly, the sand bag can be effectively protected and the surface of the sand bag is prevented from being polluted by dirt such as dust on the floor of the sport place.
As known in the art, the larger the hitting force is, the larger the swing amplitude is, and vice versa, for the same sandbag, and the maximum swing amplitude of the sandbag is considered that the sandbag does not fall to the floor after being hit and can automatically return to the vertical state without being manually supported (centered). However, the maximum swing or swing distance of the prior art sandbag is usually determined by the manufacturer, that is, when the sandbag is used in a body forging place, the manager of the body forging place cannot adjust the maximum or minimum swing distance of the sandbag. Thus, there are at least two disadvantages: first, if the sandbags of the same specification produced by sandbag manufacturers are respectively arranged in a juvenile activity experience area, an adult exercise area, a lady activity area and the like by a stadium, the physical abilities of different groups are remarkably different, and the sandbags are specifically expressed as different hitting forces. When a group with relatively strong physical abilities such as the aforementioned adults, particularly strong men, hits the sandbag, the resistance of the sandbag is often considered to be insufficient and not satisfactory, while for children and women, the sandbag is considered to be too stiff and stiff to the touch and has fun. Perhaps, some people may think that the aforementioned contradiction can be solved as long as sandbag manufacturers respectively produce appropriate sandbags for different groups of situations, but the applicant thinks that producing sandbags with different maximum swings for different groups of people causes resource waste and also significantly increases the acquisition cost of stadiums; secondly, because the sandbag is tilted and returned by the elastic device between the sandbag body and the base, such as a spring, the elastic device can be fatigued after the sandbag is in service for a period of time, and the sandbag can be fallen down to the ground or even can not be used after the elastic device is over-fatigued.
How to solve the above technical problems, which is troubled by the stadium, namely the use manager of the sandbags, and troubled by the manufacturers of the sandbags, for a long time, so that the applicant has made an active and beneficial design, and finally the technical scheme to be described below is formed and the simulation test is carried out in the test room of the applicant under the security measures, and the result proves that the method is feasible.
