Description

The safe anti-theft type key spring plate structure of POS machine

Technical field

The utility model relates to POS machine field technologies, refer in particular to the safe anti-theft type key spring plate structure of POS machine.

Background technique

POS is a kind of multi-functional terminal end, it be mounted on the franchised business of credit card and accept in site with computer join At network, it can be achieved with electronic funds and transfer accounts automatically, it has the function of to support consumption, pre-authorization, inquiry into balance and transfer accounts, and makes It uses safely, quickly, reliably, is widely used in the places such as supermarket, chain store, hypermarket, restaurant.

Since POS machine is directly facing user, it is easy to carry out rogue attacks by some criminals and distorts, these attacks remove It further include machine of tearing open, cutting, etching, modification circuit, replacement device blocks etc. except software virus, wooden horse.Especially band key POS machine, criminal is easy to obtain the important informations such as password of user's input by removing the modes such as key, leads to POS machine Safety it is not high.Moreover, material is common for common POS machine key, cause that key electric conductivity is bad, haptoreaction is insensitive, And key cannot be anti-skidding, affects user experience.

Therefore, it is necessary to be improved to current POS machine press-key structure.

Utility model content

In view of this, the utility model is in view of the existing deficiencies of the prior art, main purpose is to provide a kind of POS machine use Safe anti-theft type key spring plate structure, can solve that current POS machine safety is not high and key electric conductivity problem of poor.

To achieve the above object, the utility model is using following technical solution:

A kind of safe anti-theft type key spring plate structure of POS machine, includes elastic slice main body, the two sides pair of the elastic slice main body Claim integrally to extend and has the leg that connection is welded and fixed and be connected with POS machine corresponding circuits with POS machine, the elastic slice main body and leg It is metal steel disc, the plating inner surface of the elastic slice main body is formed with a silver coating.

As a preferred embodiment, the rounded arced configuration of elastic slice main body, the cross section of two legs are arc-shaped.

As a preferred embodiment, the elastic slice body periphery has a circular fold, and leg on circular fold in extending Out.

As a preferred embodiment, the outer surface center of the elastic slice main body is concaved with positioning groove, corresponding, should The inner surface center of elastic slice main body is inwardly convexly equipped with contact salient point.

As a preferred embodiment, the outer surface of the elastic slice main body is covered with anti-skidding layer of silica gel.

The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology Known to scheme:

One, there is leg by symmetrically integrally extending in the two sides of elastic slice main body, cooperation welds two legs and POS machine solid Determine and connection is connected with POS machine corresponding circuits, so as to form safe anti-theft type key spring plate structure, when criminal dismantles When POS machine, leg loosens, and equipment powers off immediately, while starting software destruct system, and all user informations of POS machine are all clear It removes, it is safe to guarantee that user uses.And it is formed with a silver coating in the plating inner surface of elastic slice main body, silver has excellent lead It is electrical, therefore its electric conductivity that can effectively enhance elastic slice main body, so that the haptoreaction of key is sensitiveer.

Two, by being covered with anti-skidding layer of silica gel in the outer surface of elastic slice main body, the anti-of elastic slice main body can effectively be enhanced Sliding effect, promotes the usage experience of user.

For the structure feature and effect for more clearly illustrating the utility model, come with reference to the accompanying drawing with specific embodiment pair The utility model is described in detail.
