Abstract

The application provides an anti-exchange device, which aims to solve the problems of complex structure and poor triggering reliability of an anti-exchange device in the prior art. The technical scheme provided by the application comprises a first main body and a second main body which are respectively arranged at two sides of the commodity. The first main body comprises a containing cavity, and a fixed first magnetic piece and a movable second magnetic piece are arranged in the containing cavity. The second body includes a third magnetic member. In the original state, the second magnetic element is positioned at the bottom of the accommodating cavity and is mutually attracted with the third magnetic element at intervals of commodities. When the first body is separated from the second body, the second magnetic element moves from the bottom to the top of the cavity and is attracted by the first magnetic element. By adopting the magnetic force system formed by the first magnetic part, the second magnetic part and the third magnetic part, the triggering process only needs to rely on magnetic force change, the response is rapid, the risk of mechanical locking is avoided, the triggering reliability is obviously improved, meanwhile, the number of parts is reduced by a simplified structure, and the manufacturing cost and the assembly difficulty are reduced.

Description

Anti-exchange device Technical Field The application relates to the technical field of commodity packaging, in particular to an exchange-preventing device for preventing commodities from being returned after being unpacked or opened for use. Background With the rapid development of electronic commerce, online shopping has become an important channel for consumers to purchase goods such as clothes, bags, luxury goods, and the like. While guaranteeing consumer rights and interests, the policy of unordered returns in seven days also promotes actions such as malicious returns or commodity exchange, and serious economic losses are caused for merchants. In order to cope with the above problems, various anti-exchange technical schemes are presented in the market. The chinese patent application CN121148234a can verify whether the commodity is unpacked or exchanged by a method of multi-magnet linkage and pigment tube development.
