Description

Technical Field

[0001] The utility model relates to the technical field of handheld card readers, in particular to an RFID card reader for a high-security computer. Background Technique

[0002] RFID is the English abbreviation of radio frequency identification. Generally speaking, an RFID card reader is an automatic identification device that can read the data of electronic tags. According to the different frequencies of reading tags, it is divided into low-frequency, high-frequency, and ultra-high-frequency card readers. The RFID card reader needs to be used together with an RFID antenna to read the tag information.

[0003] There are many types of existing RFID card readers, and the handheld RFID card reader is one of them. A touch screen display is provided on the handheld RFID card reader for the user to operate. Since the touch screen display is not provided with a protection structure and is in a naked state, the display screen is at risk of colliding with hard objects and breaking.

[0004] Therefore, we propose an RFID card reader for a high-security computer. Content of the Utility Model

[0005] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides an RFID card reader for a high-security computer.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme.

The protective frame is integrally L-shaped, and the upper side wall surface of the card reader main body is in a square shape with a hole in the middle. There are two protective baffles arranged between the right vertical end of the protective frame and the wall surface close to the card reader main body. The upper side end faces of the two protective baffles are rotatably connected together. Connecting sliding grooves for limiting are opened on the front and rear wall surfaces of the vertical end of the protective frame. Movable clamping blocks for limiting are movably installed inside the two connecting sliding grooves. The front side wall surfaces of the right protective baffle are movably installed on the wall surfaces of the movable clamping blocks on the same side through rotating shafts. A positioning card plate is fixedly installed on the lower side wall surface of the left protective baffle. A connecting card slot is opened on the upper side wall surface of the left horizontal end of the protective frame. The positioning card plate is adapted to the connecting card slot, and a limiting mechanism for positioning and locking the positioning card plate is arranged on the connecting card slot.

[0007] Preferably, a protective belt for limiting and two fixing rods are fixedly installed on the right side wall surface of the vertical end of the card reader main body. Both of the two fixing rods are located below the position of the limiting stop rod, and the outer wall of the protective belt movably passes through the position between the two fixing rods.

[0008] Preferably, the distance between the protective belt and the two fixing rods is matched, and a limit stop rod arranged in a horizontal state is rotatably installed between the wall surfaces where the two fixing rods are close to each other.

[0009] Preferably, the protective belt is located at the left side of the limiting barrier rod, and the right side wall of the protective belt is fixedly mounted with a first Velcro and a second Velcro for positioning, and the first Velcro is located below the second Velcro.

[0010] Preferably, the limiting mechanism comprises a limiting clamping hole for positioning, and a positioning bolt for limiting is threadedly connected to the front wall of the protective frame, and the positioning bolt and the interior of the limiting clamping hole are adapted to each other.

[0011] Preferably, an auxiliary knob is fixedly mounted on the front wall of the positioning bolt to facilitate its rotation, and an auxiliary push plate is fixedly mounted on the left wall of the left protective baffle to facilitate its operation.

[0012] Beneficial Effects

[0013] The utility model provides an RFID card reader for a high-security computer, which has the following beneficial effects:

[0014] (1) This is an RFID card reader for a high-security computer. During use, when the card reader body is used up, the two protective baffles can be moved upward until they cannot move anymore. The two protective baffles are then flipped over and laid flat on the upper wall of the card reader body. This can protect the touch screen display on the card reader body and reduce the risk of it breaking. In addition, the two protective baffles can be positioned by a limiting mechanism to improve their stability. During the movement of the two protective baffles, the movable card block will move inside the connecting slot to improve the stability of the movement of the two protective baffles.

[0015] (2) This is an RFID card reader for a high-security computer. During use, the positioning card plate can be inserted into the interior of the connecting card slot, and then the auxiliary knob can be rotated to make the positioning bolt insert into the interior of the limit card hole to achieve the positioning of the protective baffle. In addition, when using the card reader body, the three middle fingers can be passed through the position between the protective belt and the vertical end of the card reader body, and then the protective belt can be turned to the right to stick the first Velcro and the second Velcro together. In this way, the three fingers can be positioned to prevent the risk of the card reader body falling. BRIEF DESCRIPTION OF THE DRAWINGS
