Embodiment 1

[0032] A mildew-resistant round bamboo walking stick with adjustable height is as follows:

[0033] (1) High-temperature saturated steam treatment of small-diameter round bamboo. The fresh 25mm-diameter bamboo stalks are cut into 93mm lengths according to the requirements, and the inner nodes are cut to the side. Put the round bamboo with a small diameter on the rack of the trolley, push the trolley into the pressure tank and close the tank door, then inject saturated steam into the tank, and process it in a saturated steam pressure tank with a temperature of 183°C for 10 minutes. Then pass the steam in the tank to other pressure tanks that need to be treated to release the pressure.

[0034] In the step (2), the end of the round bamboo is bent into a handle, and the handle end of the bamboo tube just out of the tank is heated to shape the handle.

[0035] In the step (3) drying treatment, put the bent and formed small-diameter round bamboo into a drying kiln, and dry it at a...

Embodiment 2

[0040] A mildew-resistant round bamboo walking stick with adjustable height is as follows:

[0041] (1) High-temperature saturated steam treatment of small-diameter round bamboos. Fresh Qiongzhu bamboo poles with a diameter of 25mm are cut into 85mm lengths according to requirements, and the inner nodes are cut to the side. Put the round bamboo with a small diameter on the rack of the trolley, push the trolley into the pressure tank and close the tank door, then inject saturated steam into the tank, and treat it in a saturated steam pressure tank with a temperature of 160°C for 60 minutes. Then pass the steam in the tank to other pressure tanks that need to be treated to release the pressure.

[0042] In the step (2), the end of the round bamboo is bent into a handle, and the handle end of the bamboo tube just out of the tank is heated to shape the handle.

[0043] In the step (3) drying treatment, air-dry the bent round bamboo with a small diameter until the moisture content...

Abstract

The invention relates to a mildew-proof height-adjustable round bamboo walking stick. A fresh small-diameter round bamboo is quickly heated by high-temperature saturated steam for 8-90 minutes, the round bamboo is taken out, an end part of the round bamboo is bent into a handle, and drying is performed. A bottom end of a bamboo rod is processed and then is plugged into a combined connecting piece.A diameter of an opened circular tube is reduced through rotation of an external locking nut so that an innermost telescopic rod is locked to determine a height. A handle end head of the bamboo rod is sealed and external processing and finishing are performed. The small-diameter round bamboo can be used as a novel bamboo walking stick because a bamboo tube can be ensured to have no crack and havedimensional stability during drying after high-temperature saturated steam treatment so that original optimal structural strength of the round bamboo can be maintained, nutrient substances in the bamboo tube are destroyed, and the bamboo walking stick has mildew-proof and mothproof effects. The novel bamboo walking stick uses unlimited bamboo species, is low in production cost, does not add any chemical reagent, and is sustainable circular economy.

Description

technical field [0001] The invention relates to a method for preparing a mildew-proof and height-adjustable round bamboo crutch, which belongs to the technical field of bamboo processing in the wood industry. Background technique [0002] As a biological material, bamboo is one of the best raw materials for structural materials in plants. The bamboo cylindrical structure is a wonderful structure formed naturally. This structure conforms to the equal-strength design principle in material mechanics. It has high strength, It has the characteristics of good elasticity, stable performance and low density. Because the round bamboo wall is thin and hollow, bamboo is a light and high-strength material. Our ancestors used it as building materials and daily handicrafts. Bamboo crutches are one of the uses, helping people support when climbing or walking. Because there are nutrients such as starch in the parenchyma cells of bamboo, fresh bamboo is easy to mildew and insects. Moreover...
