In the figure: 1. a fixing plate; 2. a locking plate; 3. a support leg; 4. a tension spring; 5. a connecting shaft; 6. a slide base; 7. a traveler; 8. a ball bearing; 9. an arc-shaped slot; 10. a buffer spring; 11. a slide plate; 12. a ground plate; 13. a wear end.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a bicycle single-support ladder capable of reducing abrasion comprises a fixing plate 1, a locking plate 2, supporting legs 3 and tension springs 4, wherein the bottom of the fixing plate 1 is connected with the upper portion of the locking plate 2, a cavity with a downward opening is formed in the bottom of the locking plate 2, a connecting shaft 5 is mounted on the inner wall of one side of the cavity, one end of the connecting shaft 5 is connected with the top end of the supporting leg 3, a sliding seat 6 is mounted at the upper end of the supporting leg 3, a sliding column 7 is mounted on the sliding seat 6, a ball 8 is mounted at one end of the sliding column 7, and the ball 8 is abutted to the inner wall of one side of the cavity;

arc wall 9 has been seted up on one side surface of jam plate 2, and ball 8 rolls and installs in arc wall 9, and the one end of extension spring 4 is articulated with the surface of jam plate 2, and the other end of extension spring 4 is articulated with the bottom surface of landing leg 3.

The surface of slide 6 has been seted up the spout, installs two buffer spring 10 in the spout, and slide 11 is installed to two buffer spring 10 with one end, and the one end of traveller 7 is connected with one side of slide 11, and ground plate 12 is installed to the bottom of landing leg 3, and wear-resisting end 13 is installed to the bottom of ground plate 12, and the bolt hole has been seted up on the surface of fixed plate 1.
