Abstract

The utility model discloses a rotary leg twisting machine which mainly consists of a rack, an oscillating rod, two pedals and two elastic ropes, wherein the center of the oscillating rod is rotatably connected with the middle part of the rack; the pedals are rotatably arranged at the two ends of the oscillating rod symmetrically; the inner ends of the elastic ropes are in hanging connection with the middle part of the rack in a dismountable way; and the outer ends of the elastic ropes are connected with the outer end of the oscillating rod. As the rotary leg twisting machine mainly comprises the rack, the oscillating rod, the pedals and the elastic ropes, the structure is simpler; as a plurality of clamping grooves are formed on the rack, the clamping ends of the elastic ropes can be clamped with the clamping grooves as required; therefore, the elasticity of the elastic ropes is regulated, and the force regulating is very convenient.

Description

The leg machine is turned round in rotation

Technical field

The utility model relates to a kind of body-building apparatus, particularly relates to a kind of rotation and turns round the leg machine.

Background technology

Along with rapid economy development, people are to the continuous lifting of healthy pay attention to day by day and living standard, make the use of health equipment increasingly extensive, people are also more and more to the functional requirement of health equipment, except requiring it to have the function of tempering limbs, also wish to have other functions such as physiotherapy, massage, fitness.Along with the rapid surge of clerical workforce and white collar personnel number, and in the face of the huge social operating pressure, the problematic people of waist leg is more and more, can also revise and function such as fitness the waist leg when people urgently wish to have a kind of fitness equipment to have the limbs of exercise.

The utility model content

The purpose of this utility model is to provide a kind of rotation simple in structure, easy strength of adjustment to turn round the leg machine.

For achieving the above object, technical solution of the present utility model is:

The utility model is that the leg machine is turned round in a kind of rotation, and it mainly is made up of frame, fork, pedal, stretch cord; The central rotatable central rack that is connected of described fork; Described pedal has two, and rotatable respectively symmetry is installed in the two ends of fork; Described stretch cord has two, and its inner is articulated in central rack removably, and the outer end of stretch cord is connected the outer end of fork.

Both sides in frame upper surface, relative fork and frame junction are provided with two position-limited wheels, a pulley respectively side by side, the middle part of described stretch cord pass two between the position-limited wheel engagement groove and pulley after around to the frame bottom surface, articulate with draw-in groove on the frame bottom surface.

Described draw-in groove has a plurality of.

The utility model also comprises rotating disk, bearing; Be provided with on the bearing block at the two ends of fork, described bearing is nested with in this bearing block, the axis of rotating disk be located in the dead eye and its traversing through end by the chuck longitudinal spacing.

Described fork central authorities are provided with sleeve pipe, and this sleeve pipe is socketed in the rotating shaft that is positioned at central rack by bearing is rotatable.

After adopting such scheme, because the utility model mainly is made up of several parts such as frame, fork, pedal, stretch cords, structure is comparatively simple; Again since the draw-in groove of the utility model on frame have a plurality of, the joint end of stretch cord can have need with a plurality of draw-in grooves in one carry out clamping, thereby regulate the elastic force dynamics of stretch cord, dynamics is regulated very convenient.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

The specific embodiment

As shown in Figure 1, the utility model is that the leg machine is turned round in a kind of rotation, it mainly as shown in Figure 3 by frame 1, fork 2, pedal 3, stretch cord 4, rotating disk 5(), position-limited wheel 6, pulley 7, bearing 81(as shown in Figure 3), bearing 82(as shown in Figure 2) form.

Central rotatable frame 1 middle part that is connected of described fork 2; Described pedal 3 has two, and rotatable respectively symmetry is installed in 2 two ends of fork; Described stretch cord 4 has two, and its inner is articulated in frame 1 middle part removably, and the outer end of stretch cord 4 is connected the outer end of fork 2.

As Fig. 1, Fig. 5, shown in Figure 8, at the upper surface of frame 1, fork 2 is provided with two position-limited wheel 6(respectively as shown in Figure 4 side by side with the both sides of frame 1 junction relatively), a pulley 7, the middle part of described stretch cord 4 pass two between the position-limited wheel 6 engagement groove and pulley 7 back around to frame 1 bottom surface, articulate (as Fig. 6, shown in Figure 7) by the draw-in groove 11 on trip 41 and frame 1 bottom surface, in the present embodiment, draw-in groove 11 has four, and the quantity of draw-in groove can be decided as required.

As shown in Figure 3, be provided with on the bearing block 21 at the two ends of fork 2, bearing 81 is nested with in this bearing block 21, the axis 51 of rotating disk 5 be located in bearing 81 holes and its traversing through end by chuck 52 longitudinal spacings.

As shown in Figure 2, described fork 2 central authorities are provided with sleeve pipe 22, and this sleeve pipe 22 is socketed in the rotating shaft 12 that is positioned at frame 1 middle part by bearing is rotatable.

Exercise state figure of the present utility model:

Practitioner's bipod can step down in respectively on the pedal 3 of being located at fork 2 two ends, does to turn clockwise 360 ° (as shown in Figure 9) and be rotated counterclockwise 360 ° (as shown in figure 10).

Emphasis of the present utility model just is: stretch cord wears by position-limited wheel, pulley and is fixed on the frame.

The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
