Description

A kind of Height Adjustable motion high ladder

Technical field：

The present invention relates to sports goods technical field, more specifically to a kind of Height Adjustable motion high ladder.

Background technology：

People catch the cross bar of body-building high ladder by takeofing, and make that body is hanging, stress on both hands cross bar leapfrogs, from one end The other end is proceeded to, shoulder, buttocks flexibility can be promoted by repeatedly reciprocal exercise training, strengthened upper limbs, waist, back, chest Portion, abdominal muscular strength, improve the coordination ability.The popularization of outdoor body-building high ladder causes people to be widely used, but actual In life, as the height of people differs, so as to the height design of body-building high ladder idler arm cannot be accomplished to be adapted to height gap very , there is the limitation for being limited to user's height in the use of big people.

Therefore China Patent No. is a kind of high ladder for body building of CN103566516A, and which passes through between adjusting yoke part and column Half-open and position of the formula structure on column difference, realize the regulation of idler arm height, the people for facilitating height gap to differ Use, but its effect is limited, and adjustable range is little, it is impossible to fully meet.

The content of the invention：

The purpose of the present invention is to overcome the deficiencies in the prior art, there is provided a kind of Height Adjustable motion high ladder, and it is by turning Dynamic cylinder, realizes lifting the regulation up and down of body, and so as to meet different lifting requirements, its expanded reach is big, and effect is good, efficiency It is high.

The present invention solves the scheme of the technical problem：

A kind of Height Adjustable motion high ladder, including four bases, are hinged with rotating cylinder at the top of the base, rotate In the middle part of the top end face of cylinder have the upwardly extending post that is spirally connected, the post that is spirally connected be screwed onto lifted body bottom surface in the middle part of have be spirally connected Kong Zhong, the lower end of swing handle are hinged on the side wall of rotating cylinder, and the top of swing handle is pressed against the side wall of rotating cylinder On, nested in the detent having on the side wall of rotating cylinder and be fixed with permanent magnet blocks, the top absorption of swing handle exists In permanent magnet blocks；

The two ends of upper transverse beam are fixed with contiguous block, and two contiguous blocks are fixed on the corresponding lifting body in left and right two, The two ends of two longitudinal beams are weldingly fixed at the left and right two ends of two upper transverse beams, and the two ends of multiple intermediate beams are weldingly fixed on On two longitudinal beams.

The bar portion of fixing bolt extends transversely through hole and is bolted with fixation through what the top of contiguous block and lifting body had Nut and protection end cap, fixing nut are clamped between the lateral wall of protection end cap and lifting body.

The bottom two ends of described two longitudinal beams are fixed with lower tie-beam, and the two ends of bottom tie-beam are weldingly fixed on same On the bottom of two lower tie-beams of individual longitudinal beam, the two ends of multiple center vertical beams are respectively welded at fixed bottom tie-beam On longitudinal beam.

Bottom buffer board is fixed on four bases, and the bottom surface of bottom buffer board is fixed with multiple buffer springs, buffering elastic The lower end of spring is fixed with lower lock block, and lower lock block is pressed against on the ground.

The present invention prominent effect be：Compared with prior art, it realizes lifting the upper downward of body by rotating cylinder Section, so as to meet different lifting requirements, its expanded reach is big, and effect is good, efficiency high.

Description of the drawings：

Fig. 1 is the partial structural diagram of the present invention；

Fig. 2 is the partial enlarged drawing of Fig. 1；

Fig. 3 is the partial top view of the present invention；

Fig. 4 is the structural representation between the longitudinal beam of the present invention and bottom.

Specific embodiment：

Embodiment, is shown in as shown in Figures 1 to 4, a kind of Height Adjustable motion high ladder, including four bases 10, the base 10 top is hinged with rotating cylinder 11, has the upwardly extending post 12 that is spirally connected in the middle part of the top end face of rotating cylinder 11, and be spirally connected post 12 are screwed onto in the bolt apertures 21 having in the middle part of the bottom surface for lifting body 20, and the lower end of swing handle 22 is hinged on rotating cylinder 11 Side wall on, the top of swing handle 22 is pressed against on the side wall of rotating cylinder 11, and what is had on the side wall of rotating cylinder 11 determines Nested and be fixed with permanent magnet blocks 23 in the groove of position, the top of swing handle 22 is adsorbed in permanent magnet blocks 23；

The two ends of upper transverse beam 13 are fixed with contiguous block 14, and two contiguous blocks 14 are fixed on the two corresponding lift lugs in left and right On body 20, the two ends of two longitudinal beams 15 are weldingly fixed at the left and right two ends of two upper transverse beams 13, multiple intermediate beams 16 Two ends are weldingly fixed on two longitudinal beams 15.

Further, the bar portion of fixing bolt 1 is laterally passed through through what the top of contiguous block 14 and lifting body 20 had Perforation 24 is simultaneously bolted with fixing nut 2 and protection end cap 3, and fixing nut 2 is clamped in protection end cap 3 and the outside for lifting body 20 Between wall.

Further, the bottom two ends of described two longitudinal beams 15 are fixed with lower tie-beam 17, bottom tie-beam 18 Two ends are weldingly fixed on the bottom of two lower tie-beams 17 of same longitudinal beam 15, the two ends point of multiple center vertical beams 19 It is not welded on fixed bottom tie-beam 18 and longitudinal beam 15.

Further, bottom buffer board 30 is fixed on four bases 10, and the bottom surface of bottom buffer board 30 is fixed with many Individual buffer spring 31, the lower end of buffer spring 31 are fixed with lower lock block 32, and lower lock block 32 is pressed against on the ground.

Operation principle：Swing handle 22 is overturn by four people, then rotated so that rotating cylinder 11 is rotated, so as to So that four lift body and adjust about 20, use requirement is met, meanwhile, the effect of its bottom buffer board 30 is, when people takes exercise To middle skating accidentally or when not moving, can directly jump off, buffering effect is played by bottom buffer board 30, so as to play The safety of protection user.

Finally, embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, relevant technical field Those of ordinary skill, without departing from the spirit and scope of the present invention, can also make a variety of changes and modification, therefore The technical scheme of all equivalents falls within scope of the invention, and the scope of patent protection of the present invention should be defined by the claims.
