Safety handrail

Abstract

The invention discloses a safety handrail. The safety handrail comprises a handrail tube and mounting bases arranged at the left end and the right end of the handrail tube. The handrail tube comprises an inner tube and a protecting case wrapping the inner tube. Each mounting base comprises a fixing disk and a connecting tube connected with the handrail tube. Each connecting tube is provided with a protecting cover in a penetrating mode, and the protecting cover is connected with the corresponding fixing disk in a clamped mode. The two ends of the inner tube are each internally provided with a connecting column with an internal thread. Reinforcing ribs are connected between the periphery of each fixing column and the inner surface of the corresponding connecting tube. A threaded rod extending out of the corresponding connecting tube is mounted in the fixing column of the connecting tube. The extension part of each threaded rod is provided with an external thread matched with the corresponding internal thread. The inner surface of the end of the left connecting tube is provided with an annular limiting flange which is provided with at least one boss extending in the radial direction. The outer diameter of the left end of the protecting case is matched with the inner diameter of the left connecting tube. The left end of the protecting case is provided with a clamping groove matched with the corresponding boss. The outer diameter of the protecting case is equal to the outer diameter of the left connecting tube and the outer diameter of the right connecting tube.

Description

technical field [0001] The invention belongs to the field of handrails, and in particular, is a safety handrail used in bathrooms, swimming pools, aisles and the like. Background technique [0002] At present, the handrails used in bathrooms, swimming pools, aisles and other occasions are used to assist the elderly, young, women and children to get up and walk, so as to prevent the occurrence of falling accidents. The existing safety handrails are only fixed with a fixed seat at each end of an iron pipe. , its shortcomings are: the length cannot be arbitrarily extended or changed according to the needs of the site; the large number of specifications leads to heavy inventory and transportation burdens. The patent document with the patent number of CN201320194950 discloses a safety handrail. The handrail body includes a solid rod body and a protective shell wrapped around the solid rod body. In order to prevent the protective shell from rotating relative to the solid rod body,...

[0002] At present, the handrails used in bathrooms, swimming pools, aisles and other occasions are used to help old and young women and children get up and walk, so as to prevent accidents from falling. , its shortcomings are: the length cannot be extended or changed according to the site demand; the large number of specifications leads to heavy inventory and transportation burden

Patent No. CN201320194950 discloses a safety armrest, the armrest body includes a solid rod body and a protective shell covering the solid rod body, in order to prevent the protective shell from rotating relative to the solid rod body, a groove is provided on the periphery of the solid rod body, so that The protective shell has ribs that match the solid rod body, but because the solid rod body and the fixed seat are threaded, the solid rod body and the protective shell are easy to rotate relative to the fixed seat under long-term stress, and finally cause the armrest to loosen, affecting the use of the armrest safety, and the structure uses a solid rod body, which is not only heavy, but also has high production cost and difficulty. Even if the accommodation hole is set in the improvement plan, it is difficult to significantly reduce the cost
