Insulation pad with size adjustment function

Abstract

The invention relates to an insulation pad with a size adjustment function. A plurality of rectangular metal strips arranged in parallel with each other and a telescopic sliding groove rod form a rectangular heat insulating pad frame, and both ends of the rectangular metal strips slide and are embedded with the telescopic sliding groove rod; the adjacent metal strips are interleaved with an upperpull-up connecting block and a lower pull-up connecting block, an elastic rubber block is arranged between the adjacent upper pull-up connecting block and the lower pull-down connecting block, the elastic rubber block includes a first elastic rubber block and a second elastic rubber block on both sides of the bottom of the lower pull-up connecting block, the first elastic rubber block and the second elastic rubber block are respectively connected with the adjacent upper pull-up connecting block, the upper pull-up connecting block is fixed to the tops of the metal strips, and the lower pull-down connecting block is fixed to the bottoms of the metal strips; the elastic rubber block can rotate around the one side of the upper pull-up connecting block or the lower pull-up connecting block. Theinvention provides the insulation pad with the size adjustment function which has small occupied space, adjustable size and bottom ventilation and heat insulation during storage.

Description

technical field [0001] The present application relates to a kitchen utensil, in particular to a heat insulation pad with a size adjustment function. Background technique [0002] There are many potholders on the market, including plastic potholders, potholders made from layers of stitched fabric, and metal potholders. Traditional heat insulation pads, such as heat insulation pads made of pure plastic, are prone to wear and tear after long-term use, and are easily deformed after long-term support of high-temperature containers, and plastics are also easy to slip; Cleaning, after cleaning, because the multi-layer fabrics are stitched with a certain thickness, it needs to be dried for a long time before it can be used next time, and the fabric is easy to age after repeated use; heat insulation pads with metal structures are generally made into the style of support frames Insulation, in daily life, it is not convenient for storage and storage, and it cannot be stretched accordi...

Problems solved by technology

Traditional heat insulation pads, such as heat insulation pads made of pure plastic, are prone to wear and tear after long-term use, and are easily deformed after long-term support of high-temperature containers, and plastics are also easy to slip; Cleaning, after cleaning, because the multi-layer fabrics are stitched with a certain thickness, it needs to be dried for a long time before it can be used next time, and the fabric is easy to age after repeated use; heat insulation pads with metal structures are generally made into the style of support frames Insulation, in daily life, it is not convenient for storage and storage, and it cannot be stretched according to your needs

[0003] In daily life, the heat insulation pad usually has a fixed shape, which is inconvenient to adjust the size and move the heat container; let alone change the shape of the heat insulation pad and the size of the air hole

Existing heat insulation pads can meet the effect of rigid support, but have no deformable effect; can meet the effect of flexible support, but do not have the effect of rigid support; a good balance cannot be achieved in the rigidity and flexibility requirements of heat insulation pads
