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.
