Abstract

The utility model relates to an improved sand bag, which is provided with a sand bag body, and the sand bag body comprises a wrap and a filler. The wrap is covered out of the filler, the wrap has corresponding molds following different molds of the filler, and a plurality of sticking strips are sewn out of the wrap, for sticking and buckling; the filler is a mixture of solution and broken metal sheets comprising PU materials, and the mixture forms a soft structure after coagulation. The utility model has various molds, the molds with different structures can be selected by users according to requirement, and practicability is strong.

Description

The sand bag of improvement

The utility model relates to a kind of exercising device, relates in particular to a kind of sand bag of improvement.

What general body-building was on the market used ties up at hand or the sand bag enough, or the used sand pocket of general motion person, and its structure is to be its content with " sand ", and there is following shortcoming in it:

1. general body-building sand bag, all it is tied up on hand or foot to train the strength of arm and pin, this training will just can take effect for a long time, if the quality of sand bag is not good, long-time use can cause minus effect or athletic injury, and because the sand bag is be content with " sand ", it can not fix also inhomogeneously because of the stressed distribution that cause sand, causes result of use not good.

Moreover, as some boxings, tae kwon do player, use the hanging sand pocket during training, in long-time training process, situation about can break makes dust fill the air whole space, and contaminated environment.

3. be content with " sand ", its shape is fixing and do not have a variability, and under the gravity effect, it tends to sagging, can not have other function with user's needs.And the sand amount what the size of its weight is decided by, the sand amount is many, and the volume of sand bag also increases thereupon, poor practicability.

In view of this, main purpose of the present utility model is, a kind of sand bag of improvement is provided, and after it breaks, the be scattered situation on full ground of sand can not take place.

Secondary objective of the present utility model is, a kind of sand bag of improvement is provided, and it has changeableization moulding, and the user can select different Mechanical Builds as required, strengthens practicality greatly.

A purpose more of the present utility model is, a kind of sand bag of improvement is provided, and makes its weight can utilize the ratio of material and controlled, thereby can effectively control the volume of sand bag.

The purpose of this utility model is realized by following technical scheme.

A kind of sand bag of improvement is provided with sand bag body, and it comprises a wrappage and filler, it is characterized in that, this wrappage coats outside filler, and it is along with the difference of filler moulding, and has corresponding moulding, and wrappage is also made several outward and pasted band, in order to adhesive buckle; This filler is to contain the solution of PU material and the mixture of cutting metal sheet, is the structure of a softness after it condenses.

Even the utility model breaks, the sand situation on full ground of being scattered can not take place yet, and has changeableization moulding, the user can select the advantage of different Mechanical Builds as required, can improve practicality.

Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Fig. 1 is a decomposing schematic representation of the present utility model.

Fig. 2 is a schematic appearance of the present utility model.

Fig. 3 is a schematic appearance of commonly using sand pocket.

Fig. 4, Fig. 5, Fig. 6, Fig. 7 are respectively the enforcement illustrations that the utility model is used in different parts.

For further understanding technology contents of the present utility model, characteristics and effect, exemplify following preferred embodiment now, and conjunction with figs. is described in detail as follows:

See also shown in Figure 1ly, sand bag body of the present utility model comprises that a wrappage (10) and its primary structure of filler (11) thereof are as follows, wherein

See also shown in Figure 1ly, this wrappage (10) is the outer wrappage (10) of sand bag filler (11), and this wrappage (10) is along with the difference of filler (11) moulding, and different moulding, in addition, make several outside the wrappage (10) and paste band (12), in order to adhesive buckle.

This filler (11) is to utilize the solution and the cutting metal sheet (14) that contain PU material (13) to mix, and treats to be after it solidifies the flexible structure of a soft tool.

The utility model in use, it can be according to the position difference of user's use, and present different shapes and weight, use when the foot as it, can adopt corresponding shape according to the construction features of ankle, as using on wrist, also can be according to the shape of wrist joint, make the sand bag adopt the shape that adapts with it, how much its weight can be changed with the composition of cutting metal sheet in addition.

The utlity model has following advantage:

1. the utility model external shape can be as required changes with the variation of the content of sand bag inside, Make the sand bag more convenient to use, practical.

2. the utility model is the filler that employing PU solution and two kinds of materials of cutting metal sheet are the sand bag, and Change as required its ratio, and obtain multiple moulding and different weight, need to satisfy different training Want, creative, and it is simple in structure, reduces manufacturing cost.

3. inhomogeneous or sagging situation can not appear in the utility model in use, because that employing is PU The mixture of solution and cutting metal sheet is filler, so can not break through long-time impact, more can not occur Sand scatters the phenomenon on full ground.

Claims

A kind of sand bag of improvement is provided with sand bag body, and it comprises a wrappage and filler, it is characterized in that,

This wrappage coats outside filler, and it is along with the difference of filler moulding, and has corresponding moulding, and wrappage is also made several outward and pasted band;

This filler is to contain the solution of PU material and the mixture of cutting metal sheet, is the structure of a softness after it condenses.
