Embodiment Construction

[0011] figure 1 The fitness ladder shown includes a tie rod member 1 and four vertical columns 2. The tie rod member 1 is composed of two long rods 3 and a plurality of cross rods 4, and both ends of the cross rod 4 are welded to the long rods 3, respectively. The two ends of the two long rods 3 are respectively connected to the upright column 2 through the semi-opening and closing structure 5.

[0012] The semi-opening and closing structure 5 is mainly a two-half-ring structure. In the two-half-ring structure, a casing 6 is welded in the circumferential direction of the half-ring structure on the inward side. The central axis of the casing 6 is connected to the two-half-ring structure. The central axis space is vertically staggered, and the end of the long rod 3 of the tie rod member passes through it.

[0013] Each upright 2 has a number of groove structures 7 distributed along its extension direction, and the corresponding groove structures 7 are at the same height on the four u...

Abstract

The invention discloses an exercise ladder comprising a pulling rod and four posts arranged perpendicularly. The pulling rod is composed of two long rods and a plurality of transverse rods, and two ends of the transverse rods are welded to the long rods. The exercise ladder is characterized in that two ends of the long rods are connected to posts through semi-retractable structures respectively; the semi-retractable structures are dual-half-ring structures, wherein, one half-ring structure towards inside is welded to one sleeve on the circumferential direction, the central axis of the sleeve and that of the dual-half-ring structures are crossed in a spatial-perpendicular manner, and the end of one long rod of the pulling rod penetrate the sleeve; a plurality of groove structures are distributed on each post along the extending direction, and the dual-half-ring structures are embedded in the groove structures. The height of the pulling rod can be adjusted by adjusting the positions of the semi-retractable structures on the posts between the pulling rod and the posts, and convenience is provided to users with height differences for using.

Description

Technical field [0001] The invention relates to a sports article, in particular to a fitness ladder. Background technique [0002] People jump and grab the crossbar of the fitness ladder, make the body hang in the air, hold the crossbar with both hands and move forward alternately, from one end to the other. Through multiple reciprocating exercises, they can promote the flexibility of the shoulders and hips, and strengthen the upper limbs and waist. , Back, chest, abdominal muscle strength, improve coordination. The popularity of outdoor fitness ladders allows people to use them widely, but in real life, due to people's height differences, the height design of the fitness ladder rods cannot be suitable for people with large height gaps, and there are limitations in use Limitations of the height of the person. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a fitness ladder. The tie rod member and the upright column are ...
