Guide rail for climbing frame

WANG MINJIE

The invention relates to a guide rail for a climbing frame. The guide rail comprises a hollow guide rail body, a first guide wheel groove and a second guide wheel groove are formed in the left side wall and the right side wall of the hollow guide rail body in a mirror symmetry mode, and the hollow guide rail body with the first guide wheel groove and the second guide wheel groove is integrally formed in an extrusion mode. According to the guide rail for the climbing frame, the hollow guide rail body with the first guide wheel groove and the second guide wheel groove are integrally formed in anextrusion mode, no welding procedure is needed, the possibility of welding failure is eradicated, and therefore the safety of the guide rail is improved; and the guide rail for the climbing frame, which is light in weight can be manufactured only through a simple manufacturing method.

本发明涉及一种爬架用导轨，包括中空导轨主体，所述中空导轨主体的左右两个侧壁上镜像对称设置的第一导轮槽和第二导轮槽，所述中空导轨主体与所述第一导轮槽和第二导轮槽一体挤压成型。实施本发明的爬架用导轨，通过将中空导轨主体与所述第一导轮槽和第二导轮槽一体挤压成型，无任何焊接工序，杜绝了焊接失效的可能性从而提高了导轨的安全性，并且只需要简单的制造方法就可以制备重量很轻的爬架导轨。
