Abstract

The utility model discloses a sand bag, particularly a sand bag which is used for physical training of boxing, China boxing, tae kwon do, etc. The utility model is composed of a sand bag body 4, an upright rod 2 and a base 1. The utility model is characterized in that an elastic material layer and a leather cover are wrapped outside the upright rod 2 orderly and stitched to be a sand bag body 4, one end of the upright rod 2 extends out of the sand bag body 4 and is connected to the centre place of the base 1, the shape of the bottom surface of the base is a sphere which is less than a hemisphere, and the base 1 uses high density materials, so the centre of gravity of the whole sand bag is positioned on the base 1. The novel sand bag can be used by placing on the ground directly, the suspension is not required, the sphere of the base is always kept to contact with the ground when the sand bag body 4 is pressed from any direction, and the utility model is in a state of not falling over.

Description

Sand hill

The utility model relates to a kind of sand hill, specifically relates to a kind ofly to be used to box, the sand hill of athletic trainings such as free combat, tae kwon do, belongs to sports goods.

At present, along with the raising of people's living standard, the positive mushroom development of nationwide fitness programs, various thereupon sports apparatuses are also come out one after another, to satisfy sports fan's needs.Boxing is people's favorite exercises, and particularly the teenager especially likes, because it can improve the health, can temper people's courage, will and sensitivity again.Yet, existing being used to box, the common sand hill of grapple training all is to adopt suspension type, is about to common sand hill and could uses in aerial with rope hanging, it hangs heaviness, mobile very inconvenience, requisite space is big, and floor space is big, inconvenient popular use.

The purpose of this utility model just provide a kind ofly be used to box, the novel sand hill of athletic trainings such as free combat, tae kwon do, it can directly stand on ground and does not fall during use, is convenient to carrying simultaneously, and is easy to use, has decoration functions.

For achieving the above object, technical solution adopted in the utility model is: whole sand hill is made up of sand hill body, vertical rod and base three parts.Outside vertical rod, be surrounded by elastomeric layer and leather cover successively, and be sewn into the sand hill body.One end of vertical rod stretches out the sand hill body, and connects with the center of base, being shaped as less than hemispherical sphere of base end face.Base uses the high specific gravity material, makes the center of gravity of whole sand hill be positioned at base.

As further improvement of the utility model, this vertical rod is a hollow tubular, adopts between vertical rod and the base detachably to connect; Elastomeric layer is divided into two-layer, and internal layer is the hair material layer, and skin is a spongy layer, and elastomeric layer can also replace to the used sand of common sand hill.Maintain a certain distance between sand hill body and the base, the sand hill body is divided into sand hill body epimere and sand hill body hypomere by the thickness difference, and the length of sand hill body epimere and fineness degree are all less than sand hill body hypomere.The leather layer of sand hill body uses different colours collocation and multiple floral designs.

After adopting technique scheme of the present utility model, this novel sand hill must not suspend in midair and directly place the ground to use, because its base end face is less than hemispherical sphere, and the center of gravity of whole sand hill is positioned at base, according to common mechanics principle, the stressed in any direction base sphere that can both remain of sand hill body contacts with ground, is in not state.It has satisfied the required sand hill functions of athletic training such as boxing, free combat, tae kwon do like this, be convenient to simultaneously carrying again, requisite space is little, and floor space is little, easy to use, the different colours collocation and the multiple floral designs of sand hill volume surrounding also have decoration functions preferably.

Below in conjunction with drawings and Examples the utility model is done into to go up the step explanation.

Fig. 1 is a schematic perspective view of the present utility model.

Fig. 2 is the integrally-built cross-sectional schematic of the utility model.

Overall appearance of the present utility model as shown in Figure 1, whole sand hill is made up of sand hill body 4, vertical rod 2 and base 1.Maintain a certain distance between sand hill body 4 and the base 1, sand hill body 4 is divided into sand hill body epimere 5 and sand hill body hypomere 3 by the thickness difference, the length of sand hill body epimere 5 and radius are all less than sand hill body hypomere 3, like this to satisfy the needs of different action trainings such as boxing, free combat, tae kwon do, also can lower the center of gravity simultaneously, save material.One end of vertical rod 2 stretches in the sand hill body 4, and the other end carries out dismountable the connection with the center of base 1 by pin 6, can certainly be the detachable connection of other form, facilitates the dismounting, replacing, carrying of base 1 and sand hill body 4 etc. like this.Being shaped as of base 1 bottom surface less than hemispherical sphere, base 1 employed material is a cast iron in the present embodiment, it also can be other high specific gravity material, make the center of gravity of whole sand hill be positioned at base 1, can both remain the base sphere in any direction when sand hill body 4 is stressed like this contacts with ground, be in not state, satisfied the function that sand hill should possess.The internal structure of whole sand hill as shown in Figure 2; sand hill body 4 is to be surrounded by elastomeric layer 9 and leather cover 10 successively to make and form outside vertical rod 2; elastomeric layer 9 is divided into two-layer in the present embodiment; internal layer is a hair layer 7; skin is a spongy layer 8, and wherein hair layer 7 and spongy layer 8 can be respectively one deck or multilayer, and elastomeric layer 9 also can be other material in addition; get final product so long as have the soft filler of elastic force, its objective is in order to protect the sporter in training, to preserve from.The leather layer 10 of sand hill body 4 uses different colours collocation and multiple floral designs, can print or be spliced, and makes it have better decoration functions.Vertical rod 2 is a hollow tubular, like this can weight reduction, and lower the center of gravity, and save material.

As another kind of embodiment of the present utility model, the length of sand hill body 4 can prolong up to base 1, and sand hill body 4 is without separating into two sections, and is the cylindric of same radius.Elastomeric layer 9 in the sand hill body 4 can also replace with the used sand of common sand hill.
