Description

Elastic connection sand bag

Technical Field

The utility model relates to a body-building equipment field especially relates to an elasticity is connected sand bag.

Background

At present, a large number of patients or sub-healthy people have symptoms of muscle strength decline, and the main reasons are age increase, disuse muscle atrophy, nervous system diseases and myogenic diseases. Insufficient muscle strength causes a series of problems such as motor dysfunction, joint instability, posture change, pain, and the like.

To remove the cause, the most prominent way to enhance muscle strength is muscle strength training. The application of resistance is an important principle for enhancing muscle strength, the resistance mainly comes from the self weight of the body and pure external resistance, and the aim of enhancing the muscle strength cannot be achieved if the body is trained under the condition of no resistance. Therefore, the resistance-resisting training equipment such as sandbags, dumbbells and the like is widely applied to medical rehabilitation and body building. Studies have shown that it is possible to influence the exertion of the distal muscles, stabilize the spine and pelvis, improve control and balance, increase energy output, increase efficiency of coordinated limb work, reduce energy expenditure, prevent sports injuries, etc. by improving proximal stability. The core stability training is applied to the cerebral apoplexy hemiplegia patient, and the training is found to effectively improve the gait space-time parameter and the symmetry parameter of the patient, so that the gait has symmetry and stability, and the balance ability, the coordination ability, the walking ability and the gait symmetry of the patient can be improved.

Further exploration and optimization of sandbags for fitness training to provide better performance in the field of fitness equipment is a technical problem that those skilled in the art need to solve.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned technical problems, those skilled in the art need to further explore and optimize the sand bag for fitness training to provide better performance in the field of fitness equipment. The utility model provides an elasticity is connected sand bag and has been avoided because sand bag weight is single and fixed, leads to the problem of unable realization training of advancing.

The technical means of this scheme is as follows, a sand bag is connected to elasticity includes: the sand bag comprises two sand bag bodies and a fixing part, wherein the fixing part is used as a connecting piece for connecting the sand bag with a human body limb.

In this scheme, set up to be connected the sand bag body with the elasticity section, the elasticity section links to each other with the both ends of the fixed part of winding on human truck, when using, the sand bag is because connect through the elasticity section on the fixed part, the sand bag can follow because of the elasticity effect of elasticity section when human motion the elasticity section carries out irregular motion, and the change of sand bag self speed can be followed to the resistance size, and the conduction of this kind of power can take place further change under the elasticity effect, improves the training degree of difficulty, makes the human upper and lower limb that will control self in the course of motion exert oneself and balance, trains the stability of its near-end truck, and the motion is more violent, and the effect of the power that the truck received just is big more, and the human power that just need have higher equilibrium and stronger upper and lower limb, trains person's core muscle crowd.

Preferably, set up as two elasticity sections are the elastic webbing, the fixed part is the banding, one side of fixed part is provided with the magic subsides, the magic subsides are mao face and collude the face, and its two faces are strip and the area equals, and all are parallel with the fixed part. The sandbag body is of a round-cornered sheet three-dimensional structure, and the length of the elastic band connecting the two sandbags is equal.

The further technical scheme is as follows:

the utility model discloses a fixing part, including banded fixed part, hook face and hair side, the one side of banded fixed part is provided with the magic simultaneously and pastes the hair side with the hook face, when the winding human truck, the one side at magic subsides place is not with human truck direct contact, wherein the hair side with the area of hook face equals, the hair side with the hook face all sets up on the fixed part, the hair side with the hook face is in the width direction of fixed part is symmetrical, and all with the fixed part is parallel. When winding, the hair side with the face of colluding is in lie in same one side on the fixed part, two faces can partially coincide when the winding is on the truck, and work as the hair side with the face area of colluding equals, enables the hair side with the cooperation area of colluding the face is bigger, makes to paste more firmly, and will the hair side with the face of colluding set up to with the fixed part is parallel, can make two faces suit with the size of truck when the winding to reach further fixed effect. When the hair surface and the hook surface are partially overlapped to fix the fixing part on the trunk of the human body, the sandbag body can move along with the movement of the elastic belt when the elastic belt stretches and contracts in the moving state. The sandbag body is of a round-angle sheet three-dimensional structure and can be attached to the trunk of a human body during movement, the two elastic belts are the same in length, and two forces applied to the trunk of the human body during movement are the same as the forces generated by the sandbag body under acceleration.

The utility model discloses following beneficial effect has:

this scheme is provided with the elastic webbing is used for connecting two the bag body of sand bag, at the training in-process, the sand bag body is followed the elastic deformation of elastic webbing and change the motion state, and the resistance size can be followed the change of sand bag self speed and change, and the conduction of this kind of power can take place further change under the elastic force effect, improves the training degree of difficulty to according to the atress of the intensity automatically regulated truck of motion, improve the ability of human body stable posture in the motion. The improvement of the stability is beneficial to the control of the gravity center, creates a pivot for the movement of the upper limb and the lower limb, coordinates the exertion of the upper limb and the lower limb, and optimizes the generation, the transmission and the control of the force. Besides the stability training of the far-end limb, the training of the stability of the near-end trunk can establish a strong core muscle group, and the strong core muscle group has great influence on the dynamic chain function of the body.

Will the fixed part with the elasticity section sets up to the banding, sets up the sand bag body into slice fillet structure, can promote in the motion the fixed part with area of contact between elasticity section and the human truck to reduce the discomfort that the winding caused, at elasticity section swing in-process, alleviate the elasticity section with the sand bag body is touching the atress of in-process truck with the truck, alleviates skin damage. Will the collude the face with the hair side set up to the area equal and with when the fixed part is parallel the fixed part is when the fixed part winding is on the truck, the area of coincidence of setting up two faces on the fixed part for the outside of truck is bigger, makes to fix more stable when on the truck.
