[0002] PIN pads are essential computer peripherals for financial cash register systems. They are widely used in banking, telecommunications, government, transportation, industry and commerce, taxation, supermarkets, and other service industries. They are used in conjunction with banking systems, POS machines, and management systems, primarily for entering passwords. With the increasing number of bank card users and the growing popularity of card transactions, PIN pads are gaining increasing attention.

[0003] However, the existing password keyboard is relatively simple and is generally placed on the bank counter. In order to ensure the security of customers when entering their passwords, certain protective measures need to be adopted to prevent others from peeping into the passwords and causing financial losses to customers.

[0004] Currently, the commonly used protective measures are to set a corresponding protective cover on the end of the password keyboard away from the customer to block the customer's hand when using it, or to use a foldable protective cover to protect the opening. However, when these two protective structures block the password keyboard, the keyboard light will be dimmed, or customers of different heights will need to adjust their posture to ensure that they can observe the keyboard through the opening, which is inconvenient to operate. Utility Model Content

[0005] The purpose of the present utility model is to provide a bank counter password input keyboard protection device in order to overcome the defect of the above-mentioned prior art that the protective structure causes excessive obstruction of the keyboard, causing customers to need to adjust their posture before they can enter their passwords, which is extremely inconvenient to operate.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A bank counter password input keyboard protection device includes a keyboard body for password input, the device includes a fixed shell and a rotating shell; the fixed shell is provided on the keyboard of the keyboard body and is located at the upper end of the keyboard body;

[0008] The rotating shell includes a fixed plate and a shielding plate, the fixed plates are symmetrically fixed to both ends of the shielding plate, and one end of the fixed plate away from the shielding plate can be rotatably fixed to both sides of the fixed shell, and the rotating shell is located at the lower end of the keyboard body;

[0009] The shielding plate is provided with an operating port at one end close to the keyboard body and a light-transmitting window at the other end away from the keyboard body. The light-transmitting window is provided with an anti-peep film on the side away from the fixed shell. A light-emitting diode displaying corresponding numbers is provided in the keyboard, and the angle between the anti-peep film and the plane of the keyboard body is 30-60 degrees.

[0010] Preferably, the privacy film is fixed on a rotating bracket, and the rotating bracket can be rotatably fixed on the shielding plate and is located outside the light-transmitting window.

[0011] Preferably, the width of the privacy film along the rotation direction is greater than the width of the light-transmitting window.

[0012] Preferably, an induction switch is provided on one side of the operation port, and the induction switch is connected to a circuit powered by a light-emitting diode.

[0013] Preferably, a light-shielding curtain is provided on a side of the operating port away from the fixed housing, and one end of the light-shielding curtain is fixed to the upper end of the operating port.

[0034] Example 1

[0035] like Figure 1 and Figure 2 As shown, a bank counter password input keyboard protection device includes a keyboard body 1 for password input, and the device includes a fixed shell 2 and a rotating shell 3; the fixed shell 2 is covered on the keyboard 11 of the keyboard body 1 and is located at the upper end of the keyboard body 1;

[0036] The rotating housing 3 includes a fixed plate 31 and a shielding plate 32. The fixed plate 31 is symmetrically fixed to both ends of the shielding plate 32. The end of the fixed plate 31 away from the shielding plate 32 can be rotatably fixed to both sides of the fixed housing 2. The rotating housing 3 is located at the lower end of the keyboard body 1.

[0037] An operating port 33 is provided at one end of the baffle plate 32 close to the keyboard body 1, and a light-transmitting window 34 is provided at the end away from the keyboard body 1. An anti-peep film 4 is provided on the side of the light-transmitting window 34 away from the fixed shell 2. A light-emitting diode displaying the corresponding number is provided in the keyboard 11, and the angle between the anti-peep film 4 and the plane of the keyboard body 1 is 30-60 degrees.

[0038] Working Principle: When a user enters a password, they insert their hand through the operating port 33 of the shielding plate 32 into the fixed housing 2 and adjust the angle of the privacy film 4 so that they can see the illuminated keyboard 11 on the other side of the light-transmitting window 34 through the privacy film 4, allowing them to enter the corresponding password. Because the keyboard 11 can only be seen through the light-transmitting window 34, the privacy film 4 placed outside the light-transmitting window 34 only allows the light emitted by the keyboard 11 to be visible from the user's perspective; those at other angles cannot see the corresponding numbers on the keyboard 11.

[0039] The fixed shell 2 and the rotating shell 3 are covered above the keyboard body 1 to shield the keyboard 11, and a light-transmitting window 34 is provided on the rotating shell 3 for the customer to observe the keyboard 11. An anti-peep film 4 is provided on the light-transmitting window 34, and the light-emitting diodes of corresponding numbers are arranged on the keyboard 11. By adjusting the angle of the anti-peep film 4 to face the customer, the customer can see the keyboard. Due to the anti-peep film 4, people at other angles cannot see the keyboard 11, which plays a role in protecting the customer's privacy. At the same time, the light-emitting diodes arranged on the keyboard 11 enable the customer to clearly observe the keyboard 11 and enter the password, which is convenient to operate.

[0040] Specifically, the privacy film 4 is fixed on a rotating bracket, which is rotatably fixed on the shielding plate 32 and is located outside the light-transmitting window 34 .

[0041] The width of the privacy film 4 along the rotation direction is greater than the width of the light-transmitting window 34 .

[0042] By adjusting the rotating bracket, the angle between the anti-peep film 4 and the customer is changed, so that the customer can clearly see the numbers on the keyboard 11, avoiding the customer's own posture adjustment. While improving the shielding safety, it also improves the convenience of operating the shielding device and improves the customer's user experience.

[0043] In a preferred embodiment, an induction switch is provided on one side of the operating port 33, and the induction switch is connected to a circuit powered by a light-emitting diode.

[0044] An induction switch is set on one side of the operation port. When the customer's hand passes through the operation port, the induction switch is closed, the light-emitting diode is energized, and the numbers on the keyboard light up, making it convenient for the customer to use; when the customer's hand moves away from the operation port, the induction switch is disconnected, the light-emitting diode is powered off, and energy consumption is saved.

[0045] Furthermore, if Figure 3 As shown, a light-shielding curtain 5 is provided on a side of the operating opening 33 away from the fixed housing 2 , and one end of the light-shielding curtain 5 is fixed to the upper end of the operating opening 33 .

[0046] The blackout curtain 5 is made of a flexible material, and can be made of a knitted fabric or a silk fabric.

[0047] A light-shielding curtain is provided outside the operation port to shield the operation port, further improving the security of the fixed and rotating housings and the concealment of the keyboard. The flexible light-shielding curtain 5 can better fit the user's operating arm, providing better shielding effect and improving privacy and security.

[0048] Specifically, the operation opening 33 is a semicircular opening structure.

[0049] The keyboard body 1 is provided with an elastic pad 6, which is provided with a slot that matches the shape of the lower end of the shielding plate 32. There are multiple elastic pads 6, each of which is symmetrically distributed at both ends of the operating port 33 on the shielding plate 32.

[0050] A plurality of elastic pads 6 are arranged between the keyboard body 1 and the baffle plate 32. After the baffle plate 32 is rotated, the elastic pads 6 are used to fix the baffle plate 32 to reduce the collision between the baffle plate 32 and the keyboard body 1. The card groove at the upper end of the elastic pad 6 assists in fixing the baffle plate 32 to improve the stability of the baffle plate 32 during operation.

[0051] Optionally, an anti-slip pad 7 is provided on a side of the keyboard body 1 away from the fixed housing 2 .

[0052] An anti-skid pad 7 is provided at the bottom of the keyboard body 1 so that the keyboard body 1 can be stably placed on a bank counter, ensuring that the keyboard 11 remains stable when used by customers.

[0053] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
