Abstract
The utility model relates to a multi-function expander for body-building, belonging to the field of sports body building apparatuses. The multi-function expander for body-building comprises a rotating disk box whose outer margin is coiled by a group of expandable ropes and which is provide with a shaft hole inside and a center shaft. The rotating disk box and the center shaft are connected by an elastic spring member to compose an elastic rotating disk which can rotate around the shaft. When the multi-function expander for body-building is used, the group of expandable ropes which is coiled on the rotating disk box is outward pulled by two limbs, and simultaneously, the elastic spring member is held tightly. When the external force disappears, the elastic spring member makes the elastic rotating disk return and the group of expandable ropes automatically retract. The multi-function expander for body-building has the advantages of small size portability and even pulling force, being very suitable for exercising muscles of lower limbs.
Description
The utility model relates to a kind of omnidistance chest expander of body-building multipurpose that is made of the elastic force rotating disk, and it belongs to a kind of physical fitness equipment.Present chest expander product all has one group of elastic component as one group of spring or stretch cord, and the limbs connector at elastic component two ends, firmly expand the length of the two ends elasticity of extension member of chest expander by limbs, utilize elastic component that limbs are produced opposition and reach the purpose that exercises one's muscles.Weak point is that chest expander is longer from body when being in static state, can not carry out omnidistance pulling force to muscle and temper and carry inconvenience.
The purpose of this utility model is to avoid above-mentioned technical deficiency and a kind of elastic component is provided is the omnidistance chest expander of body-building multipurpose of elastic force rotating disk.
The purpose of this utility model can reach by following measure: the omnidistance chest expander of body-building multipurpose is made of elastic component and limbs connector.It is characterized in that elastic component is an elastic force rotating disk.Described elastic force rotating disk is by the rotating disk box that axis hole and central shaft are arranged, and one group of spring member constitutes.One group of pulling force rope is drawn in above-mentioned rotating disk box outer rim coiling.Above-mentioned spring member is fixedlyed connected with the rotating disk box with the axis body other end around central shaft one end, forms an elastic force rotating disk and can rotate around the axis with rotating automatically the elastic force rotating disk that pulling force rope of coiling can be drawn out and can withdraw automatically on it.
The purpose of this utility model can also reach by following measure: above-mentioned pulling force rope is a nylon rope, stretch cord or the union body of the two; Spring is that metal dish is around helical spring or torsionspring; The elastic force rotating disk fixedly places in the container that the pulling force rope outlet is arranged of a metal or plastic material system by central shaft; Container is equipped with one group of pulling force rope guides pulley into; The omnidistance chest expander of body-building multipurpose can have one group of elastic force rotating disk group or two elastic force rotating disk group that are cascaded by pulling force rope that are connected side by side with a central shaft.
The utility model has following advantage than present product technology:
1. the spacing very short limbs that make in chest expander two ends were closely both beginning to carry out the pulling force exercise that omnidistance pulling force exercise is particularly suitable for positions such as lower limb.
2. volume is urinated in carrying.
3. tensile load is more even in the omnidistance stage of pulling force.
The drawing of accompanying drawing is described as follows:
Accompanying drawing 1 is the front view of the omnidistance chest expander of body-building multipurpose.
Accompanying drawing 2 is the side view of the omnidistance chest expander of body-building multipurpose.
Accompanying drawing 3 is the front view of the omnidistance chest expander of a kind of two-way body-building multipurpose.
Accompanying drawing 4 is the front view of the omnidistance chest expander of a kind of unidirectional body-building multipurpose.
Embodiment one. with reference to accompanying drawing 1 and accompanying drawing 2.There is the garden shape rotating disk box (1) of axis hole (8) at center and passes between the central shaft (2) of axis hole a flat metal spiral coiling spring (3), both ends of the spring is fixedlyed connected with central shaft with rotating disk box wall respectively, constitutes an elastic force rotating disk that can rotate around the axis.The elastic force rotating disk is placed in the canister box (6) that pulling force rope outlet (5) arranged by central shaft, and central shaft and container wall are fixed.The rotating disk box outer rim of elastic force rotating disk connects and coils one group of nylon pulling force rope (4), and the elastic force turntable structure that pulling force rope is drawn the back other end and a same structure connects mutually.Container is with a limbs connector (10), two limbs are held container respectively and are firmly outwards pulled out pulling force rope and force elastic force dial rotation screwing spring (3) during use, pulling force is removed rear spring and is returned to the initial position state, and pulling force rope is regained in the revolution of elastic force rotating disk.
Embodiment two.With reference to accompanying drawing 3.Be the omnidistance chest expander of a kind of two-way body-building multipurpose.Two have same structure rotating disk box (1) be connected to form the elastic force rotating disk of two direction of rotation arranged side by side by one a group of metal spiral coiling spring (3) and a central shaft (2) that is fixed on the container wall.On each elastic force rotating disk terminal pad around with draw two pulling force ropes that are bound up by nylon rope (4) and stretch cord (16), draw towards both sides respectively after the assembly pulley (9) on the plastic containers box (7) changes direction of pull through device, the pulling force rope end has the limbs connector (12) of attached velcro (13).
Embodiment three.With reference to accompanying drawing 4.Be the omnidistance chest expander of a kind of unidirectional body-building multipurpose.Have elastic force rotating disk and limbs connector (10,12).Rotating disk box (1) outer rim of elastic force rotating disk has coiling pulling force rope structure (15), a central shaft (2) passes rotating disk box axis hole and is fixed on the container wall, one group of torsionspring (2) is coiled on the central shaft one end and is connected the other end with the container wall and is fixed on rotating disk box wall, and rotating disk box outer rim is coiled one group of nylon pulling force rope (4) and drawn in the same direction after pulley (9) changes through guiding into.The pulling force rope end has the limbs connector (12) of band velcro (13).
