Abstract
The utility model discloses an elastic string stretching mechanism, which includes an upper bracket, a lower bracket and a plurality of elastic strings, wherein the upper bracket is fixed above an upright post of fitness equipment, the lower bracket is close to a hook of the fitness equipment and fixed under the upright post of the fitness equipment, the upper ends of the elastic strings are fixed on the upper bracket, and the lower ends of the elastic strings are hung on the hook or the lower bracket. The utility model can provide damping required by an exerciser, the occupied space is small, the operation is convenient and the safety factor is high.
Description
Technical field
The utility model relates to the fitness equipment field, relates in particular to a kind of stretch cord drawing mechanism of body-building apparatus.
Background technology
The existing body-building apparatus that is used for the both arms stretching (as chest expander etc.), its structure roughly is such: the holding rod assembly is connected with steel wire rope, and steel wire rope is connected with balancing weight through being fixed in to pass through to link up with behind the assembly pulley on the column.Quantity by the plus-minus balancing weight in motion process reaches needed damping.But use balancing weight that needed damping is provided, have following shortcoming: the balancing weight volume is big and heavy, causes that occupation space is big, the plus-minus balancing weight is regulated the damping inconvenience and safety coefficient is low.
Given this, the inventor through research and experiment repeatedly, has had the generation of this case at above-mentioned defective eventually.
The utility model content
The purpose of this utility model is to provide a kind of stretch cord drawing mechanism, and the person taking exercise is provided needed damping, and it takes up room little, and is easy to operate and safety coefficient is high.
For achieving the above object, the technical solution of the utility model is:
A kind of stretch cord drawing mechanism comprises upper bracket, lower carriage and some stretch cords; Wherein, upper bracket is fixed in the column top of body-building apparatus, and the hook of the close body-building apparatus of lower carriage is fixed in the column below of body-building apparatus, and upper bracket is fixed in the upper end of stretch cord, and the lower end hang on hook or the lower carriage.
Described upper bracket comprises locking member and main body, and the upper end of some stretch cords locks on main body side by side by locking member.
Described lower carriage also is furnished with spring and peg, has the hanging column that hangs for stretch cord on the peg; Be arranged side by side some grooves that Open Side Down on the lower carriage, the sidewall of groove is offered chute, pack into successively from bottom to top in each groove a spring and a peg, the two ends of spring are against between the bottom and peg of groove, and the hanging column of peg then slidably is plugged in the chute.
The hanging column of described peg is downward-sloping, and the axial angle between hanging column and the peg hypomere is less than 90 degree.
The hanging column periphery of described peg is provided with the annular groove that hangs for stretch cord.
The two ends of described stretch cord are provided with and buckle.
Adopt said structure, the utility model in use can select to hang on the stretch cord radical on the hook as required, thereby selects to take exercise needed damping, and this structure operation is convenient, and is simple, saves the space, the safety coefficient height.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and the specific embodiments:
As shown in Figure 1, a kind of stretch cord drawing mechanism comprises upper bracket 10, lower carriage 20 and some stretch cords 30.Wherein, upper bracket 10 comprises locking member 101 and main body 102 and is fixed in column 11 tops of body-building apparatus 1; Lower carriage 20 is fixed in column 11 belows of body-building apparatus 1 near the hook 12 of body-building apparatus 1; The two ends of stretch cord 30 are provided with and buckle, and its upper end locks on the main body 102 of upper bracket 10 side by side by locking member 101, and the lower end hang on hook 12 or the lower carriage 20.
The lower carriage 20 of present embodiment is furnished with spring 40 and peg 50 (as shown in Figure 3 and Figure 4), has the hanging column 501 that hangs for stretch cord 30 on the peg 50, and the downward-sloping and hanging column periphery of the hanging column of peg 50 501 is provided with the annular groove that hangs for stretch cord.Axial angle between hanging column 501 and peg 50 hypomeres is less than 90 degree; Be arranged side by side some grooves that Open Side Down 201 on the lower carriage 20, the sidewall of groove 201 is offered chute, pack into successively from bottom to top in each groove 201 spring 40 and a peg 50.The two ends of spring 40 are against between the bottom and peg 50 of groove 201, and 501 of the hanging columns of peg 50 slidably are plugged in the chute.Adopt this structure, when stretch cord 30 does not use, the lower end of stretch cord 30 is hooked on the hanging column 501 of peg 50, stretch cord 30 remains on same position, make whole external form more attractive in appearance, this mechanism makes stretch cord 30 be tauted difficult drop-off when being hooked in hanging column 501 simultaneously.
The utility model is when original state, as shown in Figure 1, hang a stretch cord 30 on the hook 12, user use or the same users different when muscle power use by different way (as Fig. 2, motion or inclined lie movement are seated) time, increase damping as needs, only need 30 lower ends of the stretch cord on the hanging column 501 on the lower carriage 20 are taken off, be set on the hook 12, damping size as required selects to be set in the radical of hook 12 upper elasticity ropes 30, reduce damping as need, only need corresponding minimizing to be set in hook 12 upper elasticity ropes 30 radicals, this mechanism structure is simple, save space, easy to operate during adjusting, the safety coefficient height.
Only being a preferred embodiment of the present utility model below, is not to restriction of the present utility model, allly designs conversion that main points do according to this and all falls into protection domain of the present utility model with modifying.
