Abstract

A keel with adjustable height is characterized by a keel seat, a keel body and a positioning sleeve. The upper end face of the keel seat is provided with an adjusting screw hole / screw stem; a stem stem / adjusting screw hole matching with the above adjusting screw hole / screw stem are arrange below the keel body; the positioning sleeve is provided with a screw hole matching with the above screw stem; the bottom side of the keel seat is vertical to an axle line of the adjusting screw hole / screw stem and the upper end face of the keel body is vertical to the axle line of the screw stem / adjusting screw hole. The invention adopts a unique structure which can be lifted and can steplessly adjust the height of the keel within certain scope, which is convenient in installation; no glue, nail and clamp plate are needed during installation, which saves labor and materials; the technology is simple and the installation is fast, without installation noise, dust and rubbish, which are very easy to ensure the evenness of the floor after installation. The invention is applicable to the floor, in particular to uneven floor.

Description

technical field [0001] The invention relates to a floor keel, in particular to an adjustable height keel. Background technique [0002] Most of the traditional floor keels are integral structures, and the height cannot be adjusted. Even if there is a height-adjustable keel, its height is limited to a few grades, which is difficult to meet the requirements for installation on uneven ground floors. Contents of the invention [0003] The object of the present invention is to solve the shortcomings of the above-mentioned background technology, and propose a height-adjustable keel that can steplessly adjust the height of the keel within a certain range, so that it has the advantages of simple structure, low cost, and convenient installation. [0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: adjustable height keel, which is characterized in that the keel includes a keel seat, a keel body and a positioning slee...
