Double-hanging rotating device for making the sand and sawdust in the sandbag nearly evenly distributed

Abstract

A double-hanging rotating device for making the sand and sawdust in the sandbag nearly evenly distributed. The bottom of the bottom plate is equipped with brake casters. The shaft passes through the horizontal through hole and the cushion sleeve to be hinged with the middle part of the U-shaped frame. The screw shaft is fastened by screws. Pass through the hole in the center of the sandbag, and the two ends of the boom are respectively threaded with the upper and lower trays at both ends of the sandbag, and the upper and lower trays are respectively provided with upper and lower semicircular lifting rings, and the upper and lower lifting ropes pass through them respectively. The through holes of the upper and lower hanging nails and the upper and lower semicircular lifting rings are used to securely connect the sandbags to the rim-shaped frame. The two ends of the invention are interchangeable and the hanging sandbag has the function of nearly evenly distributing sand and sawdust, and is easy to operate and use, avoiding the single-hanging sandbag used in the past, which is soft at the top and hard at the bottom. Disadvantages of time and effort.

Description

technical field [0001] The invention belongs to the field of sports equipment, in particular to a double-hanging rotating device for sandbags. Background technique [0002] The filling in the cylindrical sandbags used for practicing Sanda boxing is usually composed of evenly mixed sand and sawdust. Large, after being hit, it tends to sink to the lower part of the target body and presents a hard state. When the instep hits the hard target body, the pain is unbearable. On the contrary, the specific gravity of sawdust is relatively easy to float to the upper part of the target body. There is a large difference in the actual required feeling; b. It takes time and effort to pour out the sand and sawdust in the sandbag and stir them evenly before putting them into the sandbag; there is a lack of reasonable devices and methods to solve the above problems. Contents of the invention [0003] In order to better solve the problems in the above-mentioned background technology, the ob...
