Detachable interval-adjustable parallel bars for physical education

Abstract

The invention provides detachable interval-adjustable parallel bars for physical education. The parallel bars comprise bottom supporting rods, lifting adjusting drums and a scaling ladder cross bar, alifting rotating bearing is fixed on the top side of each bottom supporting rod through a bolt, each lifting adjusting drum is fixedly arranged on the top side of the corresponding lifting rotating bearing through a bolt, and a threaded structure is arranged on the inner side of each lifting adjusting drum; a lifting supporting rod is embedded on the inner side of each lifting adjusting drum through a thread, and an outer-wall threaded structure of each lifting supporting rod is matched with the threaded structure arranged on the inner side of the corresponding lifting adjusting drum. Pedalsare symmetrically and equidistantly welded and mounted on the outer wall of the bottom supporting rod, the structural design brings convenience to part of people with low body height or beginners to climb the parallel bars by stepping on the pedals, so that convenience in use of the parallel bars is improved effectively.

Description

Technical field [0001] The invention relates to the technical field of physical exercise appliances, in particular to a detachable parallel bar with adjustable spacing for sports. Background technique [0002] Parallel bars are one of men's athletic gymnastics. The metal frame supports two parallel bars made of wood, plastic or synthetic metal. A typical set of parallel bars movement includes the transition between the support position, the inverted position and the hanging arm position. Athletes should perform swings in these positions, such as swings, flexion and extension, arc swings, loops, somersaults, and rest. Finally, the entire set of moves requires that you stand on the side of the bar. Parallel bars were listed as an Olympic event in 1896. [0003] After a patent search, the existing patent number is 201810052478.7. The invention belongs to the field of sports equipment and training methods, and particularly relates to a method for manufacturing and using a double-ar...

Problems solved by technology

[0006] The purpose of the present invention is to provide a detachable parallel bars with adjustable spacing for sports, to solve the problem that the existing parallel bars proposed in the above background technology are relatively traditional. There are still many disadvantages in the middle; and there are also many defects in function, such as the existing parallel bar device, which cannot adjust the distance between the parallel bars, so that it cannot be changed according to the body of the trainer, which further reduces the scope of use; and even if there is A parallel bar structure to adjust the spacing, but its adjustment performance is relatively complicated, and the convenience is poor, and the adjustment distance on both sides may be different, which will cause danger and inconvenience in use; and the height adjustment of the existing device horizontal bar is relatively difficult It is cumbersome, and the convenience of adjustment is also poor, which further causes a waste of adjustment time; and the existing device does not have the setting of a ladder, which leads to a relatively single function and poor use effect.
