Description

Technical Field

[0001] The utility model specifically relates to a fool-proof installation structure for a testing paper card. Background Art

[0002] In the prior art, the installation structure of the test paper generally consists of a card face component and a card bottom component. The card face component has a plurality of pins, limit pins and / or limit baffles, sample loading ports, observation windows, etc. of the same size and symmetrically and evenly arranged at equal intervals on both sides of the card face component. The card bottom plate generally has a limit groove, a limit baffle, and a fixed protrusion for installing the test paper. The number of fixed protrusions corresponds to the number of pins of the card face component, and the fixed protrusion is provided with a groove to adapt to the pins of the card face component. Specifically, all the pins are arranged on the card face component, and all the fixed protrusions are arranged on the card bottom component. The pins of the card face component and the grooves of the fixed protrusions of the card bottom component are in an interference fit snap-fit ​​structure similar to a keychain. Although such a design can firmly fix the card face component and the card bottom component, since the size of the test paper card itself is very small and is generally assembled manually by workers, it is easy to cause the following problems in the production process:

[0003] The test paper has detection lines, control lines and sample addition areas arranged in a specific order, corresponding to the detection observation window, control observation window and sample addition port set on the card surface component. During the assembly line installation process, workers generally line up the card bottom components, then place the test paper in the detection test paper installation limit groove of the card bottom component, and then cover the card surface component. However, due to unavoidable human negligence and the fact that the test paper is generally very small, the installation workers of the upstream test paper are prone to misplace the front and back of the test paper in the detection test paper installation limit groove, while the installation workers of the downstream card surface component generally subconsciously perform the covering operation of the card surface component. If the card surface component is covered without discovering the front and back misplacement of the upstream test paper, the detection observation window, control observation window and sample addition port will not correspond to the detection line, control line and sample addition area on the test paper, thereby reducing the production yield, and may even escape the sampling quality inspection and go directly to the hands of customers.
