Examples

Referring to fig. 1-4, the embodiment provides a physical training sandbag, which comprises a sandbag main body 3 and a plurality of straps 5, wherein the sandbag main body 3 is formed by sequentially connecting a plurality of square sandbag bodies 6 with hooks 8 through buckles 7; hanging buckles 7 are arranged on two side edges of the sandbag body 6, hooks 8 are arranged on the other two side edges of the sandbag body 6, and the hanging buckles 7 and the hooks 8 are oppositely arranged on the two symmetrical side edges; the bandage 5 is provided with three at least, fix respectively in the upper portion, middle part and the lower part of a first sand bag main part 3 side.

The working principle is as follows: the utility model discloses physical training sand bag can select required sand bag weight and quantity by oneself according to user's user demand when using, through carrying out horizontal and vertical series connection with hanging buckle 7 through couple 8 with a plurality of sand bags to can change the length and the width of sand bag main part 3, form a self required sand bag, then tie up the sand bag through bandage 5 and fix, many bandage 5 make the connection more firm, and the area of stress increases, and the flexibility ratio is strong; no matter the device is used for physical training of legs, wrists or waists, a user can freely select the required number of sandbags to be connected in series to form the required weight and shape of the sandbags, and the device is more convenient to use; even if the training of high strength in the use process, because of the form of the series connection of a plurality of sand bags, different from the conventional sand bag which is integrally formed, even if the fine sand in a single sand bag is slightly loosened, the fine sand of the whole sand bag main body 3 basically keeps a uniform state, and the phenomenon of uneven filling of the sand bag can not be caused.

In this embodiment, the number of the hooks 8 or the hanging buckles 7 on each side of the sandbag body 6 is at least 1. Through setting up a plurality of buckles 7 and couple 8 for the connection between two adjacent sand bags is more firm.

In this embodiment, the inside of the sandbag body 6 is filled with fine sand, a latex layer 62 and a rubber layer 61 from inside to outside in sequence, a spring 63 is further transversely arranged inside the sandbag body 6, and two ends of the spring 63 are respectively fixedly connected with the latex layer 62. The latex layer 62 and the rubber layer 61 can inhibit the breeding of bacteria and mites on one hand, so that the sandbag main body 3 is kept in a sanitary state, and a user is prevented from being infected with skin diseases; on the other hand, if the user accidentally falls into a hurdle, the latex layer 62 and the rubber layer 61 can play a certain role in buffering protection; when a user does physical training, the user does back and forth movement in the sandbag continuously by the aid of the movement of legs or wrists and the like in cooperation with the elasticity of the springs 63, so that the user can impact muscles of the human body to achieve the effect of relieving fatigue of the muscles of the human body.

In this embodiment, one end of the bandage 5 is provided with a lock catch 1, preferably the lock catch 1 is a metal double buckle, and two ends of the surface of the bandage 5 are respectively provided with a magic tape 2. Encircle through bandage 5 and use the position after, wear to in the metal double-button fixed with bandage 5, then paste 2 further with bandage 5 fixed again through the magic for bandage 5 is more firm with the cooperation of using the position, avoids taking place gliding phenomenon.

In this embodiment, the strap 5 in the middle portion is not on the same side as the straps 5 in the upper and lower portions. When the bandage 5 is fixed in this way, the bandage 5 is fastened by force from two sides of the use part respectively, so that the sand bag is more stable in use.

In the embodiment, the back of the sandbag body 6 is integrally provided with the edge covering layer 4. Through setting up bordure layer 4 and use position direct contact, avoid the sand bag to cause the friction and produce uncomfortable sense to the skin.

In this embodiment, the edge covering layer 4 is made of polypropylene fiber as the contact surface layer 41, and the buffer layer 42 is filled between the contact surface layer 41 and the sandbag main body 3. The contact surface layer 41 can effectively absorb sweat generated in the exercise process, meanwhile, the air permeability is improved, the buffer layer 42 can avoid impact of the sand bag on the skin, and the comfort of the skin in the exercise process is improved.

In this embodiment, the buffer layer 42 is a sponge layer or a PVE rebound adhesive layer. The sand bag is fine and soft in material, is covered with elasticity, has good shock resistance, and can effectively relieve impact force brought by the sand bag in the movement process.

In summary, the utility model discloses physical training sandbag, through carrying out horizontal and vertical series connection with a plurality of sandbags through couple and buckle, thereby can change the length and the width of sandbag main part, then tie up the sandbag through the bandage and fix, no matter be used for the physical training of shank, wrist or waist, the user can freely select required sandbag quantity to establish ties, form required sandbag heavy burden and sandbag shape, it is more convenient to use; even if the training of high strength in the use process, because of the form of the series connection of a plurality of sand bags, different from the conventional sand bag which is integrally formed, even if the fine sand in a single sand bag is slightly loosened, the fine sand of the whole sand bag main body basically keeps a uniform state, and the phenomenon of uneven filling of the sand bag can not be caused.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
