Description

Two-way scalable counter strength tube

Technical field

The utility model belongs to parts on the health and fitness facilities, and what relate to is the drag devices on a kind of enhances human body apparatus for developing muscle, particularly a kind of aerodynamic drag device.

Background technology

Drag devices in the existing enhances human body apparatus for developing muscle adopts spring or counterweight as resistance element usually.Spring element generally is used for the portable exercise apparatus, like grip rod, chest expander etc.; The monomer exercising apparatus that weight element generally is used for fixing is like vertical, horizontal chest, shank or waist fitness equipment etc.Although use the drag devices simple structure of these two kinds of elements; But they in use can only produce unidirectional counter power, and the person taking exercise only can experience unidirectional having an effect, and owing to the elasticity magnitude of spring element is fixed; Only corresponding one an of apparatus is tempered magnitude, audient's faciostenosis; Not only volume is bigger, heavy to use the drag devices of weight element, and the increase and decrease of counterweight is changed very inconvenient during the magnitude adjustment.

Summary of the invention

The purpose of the utility model is to overcome the deficiency of existing drag devices, proposes a kind of drag devices that can be common to basically in the enhances human body apparatus for developing muscle, promptly two-way scalable counter strength tube.

The technical scheme that realizes above-mentioned purpose is: a kind of two-way scalable counter strength tube; Comprise piston type tubular inflator; It is characterized in that: the afterbody of said inflator is equipped with a gas in-out control device, and this installs identical by inside and outside two set constructors and valve adjustments composite diaphragm and the main pore removable cover between two groups of composite diaphragms parallel interval are formed.Said composite diaphragm is circular, and there is main pore the centre, near excircle one pore is arranged, and the plane of composite diaphragm is fixedly mounted in the inflator perpendicular to the axis of inflator, and its excircle and cylinder inner wall form hermetic seal; Two groups of composite diaphragms are installed in the axostylus axostyle two ends that are on the inflator axis, and said removable cover is sleeved on this axostylus axostyle; Inflator is corresponding to respectively there being a groove on the barrel of two groups of composite diaphragms, driving lever one end that is used to regulate a pore opening passes groove and is connected with composite diaphragm.

A kind of improvement as above-mentioned technology; Said composite diaphragm is made up of two external partitions and a median septum, and three spacer gap cooperate, and the pore position on each dividing plate is identical; Shape is one section isocentric circular arc hole, and driving lever one end is connected with median septum and can stirs median septum makes it around spindle rotation.

As another improvement of above-mentioned technology, the piston in the said inflator can be multistage, can make the contour length of the utility model become short like this, and the flexible scope of piston rod is just bigger.

The operation principle of the utility model is: when piston stretches; Extraneous gas at first flows in inflator from the main pore of outer composite diaphragm; Air-flow make removable cover along axostylus axostyle slide and cover in main pore on the composite diaphragm, at this moment gas can only flow in inflator from a pore of interior composite diaphragm.When Piston Compression, removable cover is reversed that air-flow is pushed outer composite diaphragm to and with its main pore capping, air-flow at this moment can only flow out from a pore of outer composite diaphragm.Owing to can regulate the size of pore, making the throughput of a pore of flowing through be able to control, so the size that the stretching/resistance to compression pression of piston promptly breaks through power just can be controlled, and this control is nonrated through driving lever.

The utlity model has two-way counter power function, can be installed in stretch on the apparatus of multiple enhances human body muscular training and compress, the two-way exercise of inwardly and outwards exerting oneself; Counter power size can step-less adjustment, and the adaptation dynamics is wide in range, and it is wide to be suitable for crowd's scope.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

The two-way scalable counter of the utility model strength tube is made up of a piston type tubular inflator 2 and a gas in-out control device that is installed in the inflator afterbody.Gas in-out control device and valve adjustments composite diaphragm and a main pore removable cover 6 two group composite diaphragm between parallel interval identical by inside and outside two set constructors are formed; The plane of composite diaphragm is perpendicular to the axis of inflator 2; Be fixedly mounted in the inflator 2, as shown in Figure 1.Composite diaphragm is made up of two circular external partitions 4 as shown in Figure 3 and a circular median septum 5 as shown in Figure 4; Three spacer gap cooperate; Main pore 10 is arranged in the middle of each dividing plate, have 11, three pores of one pore to align near excircle; The shape of a pore 11 is one section isocentric circular arc hole in the present embodiment, on the excircle end face of median septum 5 near pore 11 a circular arc top internal thread hole 12 (like Fig. 3 and shown in Figure 4) is arranged; Two external partitions 4 are fixed on the inwall of inflator 2 and form hermetic seal, and the outer circumference surface of median septum 5 and inflator 2 inwalls form matched in clearance; Two groups of composite diaphragms are installed in axostylus axostyle 7 two ends that are on the inflator axis, and removable cover 6 is sleeved on this axostylus axostyle 7, and can on axostylus axostyle 7, slide; Inflator 2 is corresponding to a groove 13 (as shown in Figure 2) is respectively arranged on the barrel of two median septums 5; One end of driving lever 3 is crossed groove 13 and internal thread hole 12 on the median septum 5 spin (as shown in Figure 1); Driving lever 3 can be stirred median septum 5 makes it rotate around axostylus axostyle 7; Make median septum 5 and external partition 4 rotary shifted, thus the openings of sizes (as shown in Figure 5) of regulating a pore.

The operation principle of the utility model such as Fig. 6, Fig. 7 and shown in Figure 8; When piston 1 stretches; Extraneous gas at first flows in inflator 2 from the main pore 10 of outer composite diaphragm; Air-flow make removable cover 6 along axostylus axostyle 7 slide and cover in main pore 10 on the composite diaphragm, at this moment gas can only be mobile to inflator 2 in from a pore 11 of interior composite diaphragm.When piston 1 compression, removable cover 6 is reversed that air-flow is pushed outer composite diaphragm to and with its main pore 10 cappings, air-flow at this moment can only be from a pore 11 outflows of outer composite diaphragm.Owing to can regulate the openings of sizes of pore, making the throughput of a pore 11 of flowing through be able to control, so the size that the stretching/resistance to compression pression of piston 1 promptly breaks through power just can be controlled, and this control is nonrated through driving lever 3.

If handle 16 (as shown in Figure 9) is installed at the two ends at the two-way scalable counter of the utility model strength tube, it can be used as the less chest expander of a kind of tensile elongation, is fit to children and uses.

If two two-way scalable counter strength tube afterbodys are connected through a sleeve pipe 14 that has a plurality of pores 15, can be made into the portable inflator formula health and fitness facilities of outward appearance symmetry.If piston 1 is changed to the multi-level piston of being made up of first stage piston 8 and second piston 9 (shown in figure 10), the flexible scope of piston rod is further strengthened, reduce the monnolithic case length after the condensation.

The two-way scalable of the utility model counter strength tube can be easily installed on the multiple health and fitness facilitieses such as vertical, horizontal chest, shank or waist, and because the utility model can step-less adjustment, so the adaptation dynamics is wide in range, it is wide to be suitable for crowd's scope.
