Special box for rating coins and its installation method

Abstract

The invention relates to the technical field of grading coin storage devices, in particular to a special box for grading coils. The special box comprises an upper cover and a lower cover; the upper cover and the lower cover are each internally provided with a fixing groove; a ceramic fixing plate is installed in each fixing groove and closely attached to the interior of the fixing groove; and a plurality of limiting holes are formed in the ceramic fixing plates and internally provided with rubber fixing sleeves used for fixing the grading coins. According to the device, a traditional thought manner is changed, traditional fixing plates of soft structures are changed into hard contact structures making hard contact with the upper cover and the lower cover, the fixing plates are arranged to be made from a ceramic material, and the advantages of corrosion resistance and long using time are achieved; and because the ceramic fixing plates are closely fixed to the upper cover and the lower cover, equivalently, the thickness of the upper cover and the thickness of the lower cover are increased, and the anti-breakage capacity of the upper cover and the lower cover is improved during falling.

Description

technical field [0001] The invention relates to the technical field of rating coin storage devices, in particular to a special box for rating coins and an installation method thereof. Background technique [0002] Although the commemorative coins are made of metal, they are also vulnerable to various physical losses, and are still oxidized after being exposed to the air for a long time. For example, the rare animal coins and the Sixth National Games coins before are particularly susceptible to corrosion. There are several ways to preserve them. One is to use a coin collection book, which is a loose-leaf booklet, which can store commemorative coins and banknotes, etc. Commemorative coins of different sizes can use different loose leaves. Another common type is plastic coin round boxes. The round boxes come in different sizes and should be purchased according to the outer diameter of the commemorative coins. [0003] At present, there are many rating agencies in China to iden...

AI Technical Summary

Problems solved by technology

At present, this kind of box mainly adopts a transparent acrylic structure, and a panel for fixing graded coins is set inside the box. The panel is currently made of soft materials to prevent hard contact between the box and the graded coins. When the box falls to the ground, the rating coins inside can avoid damage due to the cushioning of the soft material, but in actual use, the situation is just the opposite when the box is dropped. Due to the soft material, the inside of the box will be violent when it falls. This will lead to two situations, one is that the graded coin is easily detached from the soft material, causing damage, and the other is that the box is broken and damaged, and because the box is in a vacuum Therefore, once the position of the internal rating coin is moved, it will be difficult to restore it to its original position. It must be re-encapsulated by a professional collection agency, which has caused great inconvenience to collectors.
