Wood shrinkage tightness closer

Abstract

The invention belongs to the technical field of wood and in particular relates to a wood shrinkage tightness closer. The wood shrinkage tightness closer is concretely made as follows: a small hoop is matched on a big hoop and can be made into many shapes and is used for beautifying or hanging. Spring steel products which are beautiful, and capable of lowering the cost and bearing the contractility of a cutting board are selected in accordance with the standard of GB / T13304 Steel Classifications; the big hoop is selected according to the size and the thickness of the cutting board; the width of the big hoop accounts for 1 / 10-4 / 10 thickness of the cutting board, the thickness of the big hoop is 1-15 mm; the width of the small hoop accounts for 1 / 30-4 / 30 thickness of the cutting board, the thickness of the small hoop is 0.2-10 mm; the small hoop can be made into any shape people like. Inner hooks on two ends of the small hoop are just hooked into flanged holes in two ends of the big hoop and are enabled to slip unlikely, the flexibility of the cutting board is resisted by virtue of the elasticity of the small spring hoop and the big spring hoop to hoop the cutting board firmly.

Description

technical field [0001] The invention belongs to the technical field of cooking, in particular to a wood expansion and contraction close follower. Background technique [0002] Existing chopping board hoops have useful bamboo, rattan, metal and plastic hoops, which are fixed with gong nails or knots at the joints. All there is a common deficiency that is due to the problem of damp or dry weather or shrinkage and expansion due to cold and heat. Some may even break or fall off, losing the function of the hoop. Contents of the invention [0003] For overcoming the problem that above-mentioned chopping block hoop exists, I find a kind of problem that can overcome because of weather wet or dry or hot and cold contraction and expansion make hoop bulge broken or come off through repeated exploration, practice in real life. The specific method is: add a small hoop to the big hoop. This small hoop can be made into various shapes, beautified or hung, portable, and can be rotated 180...
