Slope device for step

Abstract

The invention provides a slope device for a step, and belongs to the field of step structures. The slope device solves the problem that an existing step is inconvenient for wheels to pass. The slope device for the step is characterized in that several step plates are involved, the slope device comprises slope blocks, the top surfaces and the bottom surfaces of the slope blocks are parallel to eachother, the front side surfaces of the slope blocks are slope surfaces of the incline-surface structures, connecting holes are formed in the slope blocks, the two ends of the connecting holes are perpendicular to the top surfaces and the bottom surfaces of the slope blocks, the slope device further comprises connecting rods arranged in the connecting holes in a penetrating mode, limiting grooves are formed in the rod walls of the connecting rods, the hole walls of the connecting holes are provided with limiting blocks located on the limiting grooves in a sliding mode, the limiting grooves areof arc shaped groove shaped structures, moreover, the front ends and the rear ends of the limiting grooves are located at the same axial positions of the connecting rods, moreover, the included anglebetween the front end and the rear end of each limiting groove in the circumferential direction of the corresponding connecting rod is 90 degrees, moreover, the distance between the middle of each limiting groove and the top end of the corresponding connecting rod is smaller than the distance between the two ends of the limiting groove and the top end of the connecting rod, and the two ends of thecorresponding connecting rod are vertically connected with the opposite sides of every two adjacent step plates correspondingly. The slope device is convenient for wheels of a wheelchair or trunk andthe like to pass through.

Description

technical field [0001] The invention belongs to the technical field of step structures, and relates to a slope device used for steps. Background technique [0002] Existing steps generally do not have a slope function, and it is inconvenient for wheels such as wheelchairs or suitcases to pass through. If a slope is built on the steps, the space of the original steps will be occupied, which will affect the normal up and down steps. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art, and provide a kind of slope device used for steps that can improve the traditional steps and make it have an adjustable slope function to facilitate the passage of casters. [0004] The object of the present invention can be achieved through the following technical solutions: a slope device for steps, which is used for refitting steps, and the steps include several step plates arranged in parallel with each other and ...
