Bidirectional double-rigidity elastic support for garden trees

Abstract

A bidirectional double-rigidity elastic support for garden trees is characterized by comprising a supporting head (1), a supporting bar and a base (4), wherein the supporting bar comprises a hollow supporting bar (21), a first hollow loop bar (22), a second hollow loop bar (23) and a draw bar (24); the top of the hollow supporting bar (21) is connected with the supporting head (1); the bottom of the hollow supporting bar (21) is connected to the top of the first hollow loop bar (22); the first hollow loop bar (1) sleeves the second hollow loop bar (22); the draw bar sequentially penetrates in a center through hole in the top of the first hollow loop bar and a center through hole in the top of the second hollow loop bar, and coaxially penetrates in the hollow supporting bar, the first hollow loop bar and the second hollow supporting bar; and limiting stopping portions (25) are respectively arranged on the top and the bottom of the draw bar (24); a first flexible spring is clamped on the draw bar and between the two through holes; and a second flexible spring is clamped between the center through hole of the second hollow loop bar and the stopping portion on the bottom of the draw bar. By the bidirectional double-rigidity elastic support for garden trees, the trees can freely swing in the up-down direction, the left-right direction and the front-back direction, and can be protected by limiting amplitude or displacement.

Description

technical field [0001] The invention relates to maintenance of garden trees, in particular to a two-way double-rigidity elastic support for garden trees. Background technique [0002] Ancient and famous trees are living and precious cultural relics as well as non-renewable resources. Our country is very rich in resources of ancient and famous trees, but with the passage of time, many ancient and famous trees have different degrees of safety hazards after experiencing hundreds of years of wind and rain. Breaking and lodging may occur, which not only damages precious ancient and famous trees, but also endangers the lives of pedestrians and tourists. Therefore, it is necessary to provide necessary support and protection for trees with hidden safety hazards in tree structure. [0003] But the way that generally adopts at present is to install fixed support to the tree that has potential safety hazard, and this way is very unscientific. Because trees are living organisms, they ...

AI Technical Summary

Problems solved by technology

Due to long-term fixed constraints, the trees cannot swing freely in small and medium winds, which is not conducive to the self-adaptive growth and self-reinforcement of the trees. Once the fixed supports are removed, the tree itself will be out of balance.
