Embodiment 1

[0011] Embodiment 1, a double pole with adjustable height and width, including two parallel crossbars 1, and four uprights supporting the crossbar, is characterized in that: the uprights are fixed on the crossbar by the upright inner pole 2 and the installation The column sleeve 5 on the base 6 is composed of evenly distributed protrusions 3 on the surface of the inner column of the column. The upper end of the column sleeve is provided with a height adjustment bolt 4 for fixing the inner column of the column. on the same base.

Embodiment 2

[0012] Embodiment 2, a double pole with adjustable height and width, including two parallel crossbars 1, four uprights supporting the crossbar, is characterized in that: the uprights are fixed on the crossbar by the upright inner pole 2 and the installation The column sleeve 5 on the base 6 is composed of evenly distributed protrusions 3 on the surface of the inner column of the column. The upper end of the column sleeve is provided with a height adjustment bolt 4 for fixing the inner column of the column. on the same base. The bottom of column sleeve is provided with rectangular slide block 8, and rectangular slide block is installed in the strip groove 7 of base, and rectangular slide block is provided with the fastening bolt that fixed slide block is useful. People can adjust the height of the crossbar by changing the length of the inner rod inserted into the sleeve, and the distance between the two crossbars can be adjusted by moving the slider at the bottom of the column ...

Abstract

The invention discloses parallels allowing height and width adjustment and belongs to entertainment tools. Lifting of the parallels can be controlled. The parallels comprise two parallel cross bars and four columns supporting the cross bars and are characterized in that each column is composed of a column inner bar fixed on the cross bars and a column sleeve installed on bases, a height adjusting bolt for fixing the corresponding column inner rod is arranged at the upper end of the corresponding column sleeve, and the columns arranged at the same ends of the two cross bars are installed on the same base. The parallels have the advantage that the columns of the parallels are designed to be the column inner bars and the column sleeves which are in sleeve connection, the height of the cross bars can be adjusted by changing the length of the inner bars inserted into the sleeves, and the distance between the two cross bars can be adjusted by moving sliding blocks arranged at the bottoms of the column sleeves. Therefore, people can adjust the height and the width of the parallels randomly according to the body to meet the requirement for physical training.

Description

technical field [0001] The invention belongs to sports equipment, in particular to a parallel bar with controllable lifting and width. Background technique [0002] Parallel bars are commonly used gymnastics fitness equipment. Two parallel bars of wood, plastic or composite metal supported by a metal frame. Usually the height of the crossbar and the width between the two crossbars cannot be adjusted, and it is very inconvenient for students of different grades to exercise because the double poles are too high and too wide. Contents of the invention [0003] In order to overcome the lack of the height of the horizontal bar and the width between the two horizontal bars in the existing parallel bars, the present invention provides a double bar with adjustable height and width, which is not only economical Affordable and height adjustable. [0004] The technical solution adopted by the present invention to solve the technical problem is: a double pole with adjustable height...
