Abstract

A kind of movable rotary double-crossbar type high ladder, it is characterized by: four columns upper end, which is welded to connect two its lower ends of square tube, is placed in ground, four flat pipe both ends, which are welded to connect, constitutes two slideway mouths in two square tube inner faces, four pull rod upper ends are welded to connect four smooth blocks in the following, four pull rod lower ends pass through and are welded to connect above two slideway mouths and four rectangular cross bars.The beneficial effect of this high ladder is: it is arbitrarily that two hand of practitioner holds two rectangular cross bars forward to replace moving distance respectively, meet different shoulder arm thoracic dorsal strength crowds holds rectangular cross bar needs, avoids existing high ladder fixed transverse rod gauge from the drawback that can not arbitrarily move；Rectangular cross bar is held in two centres of the palm inwards, backwards, is realized and is held can arbitrarily rotating for rectangular cross bar, and forearm ulna, radius is made to be in parastate, and elbow joint bicipital muscle of arm in non-torsion tension state, which can be done, to be shunk, this is conducive to large arm, and firmly drawing body ascends high ladder.

Description

Dynamic double-crossbar type high ladder can arbitrarily be transferred

Technical field

The invention belongs to field of sports equipment, in particular to one kind can arbitrarily transfer dynamic double-crossbar type high ladder.

Background technique

Sport dictionary has description below about high ladder: " high ladder is also referred to as flat ladder or horizontal ladder, a kind of to develop general physical fitness Auxiliary appliance usually has wooden or two kinds iron.Terraced 3-5 meters long, about 40 centimetres wide, 3 centimetres of terraced Inter cross bar diameter, cross bar gauge From about 25 centimetres.2-2.4 meters of the height of terraced angle from the ground.Exercising method is to climb, and ascends the shifting started with various pendency postures Row.It is mainly used for enhancing the muscle strengths such as upper limb, shoulder belt, thoracic dorsal, the practical technical ability that training is climbed." high ladder used at present deposits Be in problem: a, since everyone shoulder arm thoracic dorsal strength is different, required cross bar spacing distance of holding is different.Fixed cross bar every What distance " about 25 centimetres " was not able to satisfy different shoulder arm thoracic dorsal strength crowds holds cross bar needs, changes fixed link gauge from being random Mobile required bar gauge from, be an outlet for solving the problems, such as this, utility model patent " alternately mobile double cross bar high ladders " compared with Solve the problems, such as that cross bar is mobile well；B, when ascending existing high ladder, " alternately mobile double cross bar high ladders ", cross is held in two centres of the palm forward Bar can make forearm ulna, radius be in crossing condition, and elbow joint bicipital muscle of arm when turning round tension state is not shunk, this is unfavorable for greatly Arm firmly pulls body and ascends high ladder.Now lack one kind in random mobile cross bar distance and any rotary type day in cross bar direction can be made Ladder, this is turned round drawing to elbow joint is avoided, and ulna and radius intersects the bicipital muscle of arm and do not shrink drawback with practical significance.

Summary of the invention

In order to preferably solve the problems, such as above-mentioned background technique, the object of the present invention is to provide a kind of removable Dynamic rotation double-crossbar type high ladder, the technical solution taken with lower component by being constituted: four columns upper end is welded to connect at two In the following, the four columns lower end is placed in ground, four flat pipe both ends are welded to connect in two square tubes inner face structure square tube At two slideway mouths, four pull rod upper ends are welded to connect four smooth blocks in the following, four pull rod lower ends pass through two slideways Mouthful be welded to connect above four rectangular cross bars.

The pull rod and slideway mouth are dynamic cooperation.

It is answered after being processed above four flat pipes contour.

Using this high ladder, its is beneficial compared with fixed link gauge used at present is from high ladder, " alternately mobile double cross bar high ladders " Effect is: it is arbitrarily, to meet different shoulder arm thoracic dorsals that a, two hand of practitioner hold two rectangular cross bars to replace moving distance forward respectively The needs for holding rectangular cross bar moving distance of strength crowd avoid existing high ladder fixed transverse rod gauge from can not arbitrarily move Drawback；B, rectangular cross bar is held in two centres of the palm inwards, backwards, is realized and is held can arbitrarily rotating for rectangular cross bar, makes forearm ulna, oar Bone is in parastate, and elbow joint bicipital muscle of arm in non-torsion tension state, which can be done, to be shunk, this is conducive to large arm and firmly pulls body Ascend high ladder.

Detailed description of the invention

The present invention is described in detail with reference to the accompanying drawings and detailed description.

Fig. 1 is the main body schematic diagram of movable rotary double-crossbar type high ladder；

Fig. 2 is the left view of Fig. 1；

Fig. 3 is the top view of Fig. 1.

Specific embodiment

Referring to attached drawing, 1 upper end of four columns is welded to connect in two square tubes 2 in the following, the four columns lower end is placed in ground Face 7, four 6 both ends of flat pipe, which are welded to connect, constitutes two slideway mouths 8, four 5 upper end of pull rod welderings in two square tube inner faces Four smooth blocks 3 are connect in succession in the following, four 5 lower ends of pull rod pass through two slideway mouths and four rectangular cross bars 4 weld above Connection.The pull rod and slideway mouth are dynamic cooperation.It is answered after being processed above four flat pipes contour.On four flat pipes It is answered after the processing of face contour.When using the high ladder, two hands hold respectively the rectangular cross bar centre of the palm can do forward, inwardly, backwards forward, Climbing movement afterwards；Two hands hold the rectangular cross bar in side two respectively can do left and right side to climbing movement.

Claims

1. a kind of movable rotary double-crossbar type high ladder, it is characterised in that: four columns upper end is welded to connect under two square tubes Face, the four columns lower end are placed in ground, and four flat pipe both ends, which are welded to connect, constitutes two in two square tube inner faces Slideway mouth, four pull rod upper ends are welded to connect four smooth blocks in the following, four pull rod lower ends pass through two slideway mouths and four It is welded to connect above a rectangular cross bar.

2. a kind of movable rotary double-crossbar type high ladder according to claim 1, it is characterised in that: the pull rod and slideway mouth For dynamic cooperation.
