sports floor with tight fit

Abstract

The invention discloses movement floors with a close fit function. The movement floors further comprise two sets of elastic pillars, two sets of elastic arms and one set of elastic pieces, wherein the two sets of elastic pillars are arranged on the two adjacent edges of the movement floors respectively and used for blocking and positioning, the elastic arms are used for making contact with the elastic pillars as the gaps of the movement floors are reduced when the temperature rises to generate deformation to provide elastic force so as to push away the movement floors and keep the movement floors making tight contact with one another, and the elastic pieces are arranged in clamping seats and used for generating deformation as the gaps of the movement floors are increased when the temperature drops to provide elastic force so as to pull the movement floors and keep the movement floors making tight contact with one another. The elastic pieces are further used for providing elastic force to pull the movement floors and be matched with the elastic force generated by the elastic arms to keep the movement floors making tight contact with one another under the situation that the elastic arms push away the movement floors when the temperature rises. The movement floors with the close fit function can make the movement floors be in close fit under the temperature change situation, so that the service life of the movement floors is prolonged, and the comfort is improved.

Description

technical field [0001] The invention relates to the field of plate decoration, in particular to a sports floor with a close fit function. Background technique [0002] Sports flooring is a floor specially developed for sports venues using polyvinyl chloride materials. Specifically, it uses polyvinyl chloride and its copolymer resin as the main raw material, adding fillers, plasticizers, stabilizers, colorants and other auxiliary materials. Produced on a sheet-like continuous substrate by a coating process or by calendering, extrusion or extrusion. Divided into indoor sports floors and outdoor sports floors, indoor sports floors generally include professional sports wood floors, PVC plastic sports floors, acrylic (polyurethane) sports floors, rubber floors, etc. Generally, it is made of laminated multi-layer structure, and generally has a wear-resistant layer (including UV treatment), a glass fiber layer, an elastic foam layer, and a base layer. Sports floors are divided in...

AI Technical Summary

Problems solved by technology

[0003] However, we found some deficiencies during our usual use. Thermal expansion and contraction are basically applicable to all objects. In the existing situation, when the sports floor undergoes thermal expansion and contraction, there will be gaps or deformations, which will affect the effect of use. and comfort, but also damage the life of the sports floor itself
