[0002] A gas pump is a device used to refuel vehicles. After refueling, a transaction must be conducted using a manual card reader on the gas pump. The card reader is a common payment terminal used to read the customer's bank card, credit card or gas card information.

[0003] When using an existing card reader, insert the bank card or electronic fuel card with the chip facing down into the card reader slot, so that the chip on the card contacts the contacts inside the card reader. Make sure the card is fully inserted. When you feel the card reader secure the card, the card reader will establish a connection with the card chip through the contacts and read the data on the card.

[0004] However, in actual use, since the slot on the card reader is larger than the size of the card, if the card is slightly bent after frequent use, putting it into the slot will cause the card to separate from the chip and make it difficult to contact, which will affect the card reading effect. Utility Model Content

[0005] The utility model provides a manual card reader for a gas station, which aims to solve the problem that the slot on the existing card reader is larger than the size of the card. When the card is slightly bent after frequent use, the card chip will be separated from the card when it is put into the slot, making it difficult to contact, which will affect the card reading effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a manual card reading device for a gas station, comprising a shell, the shell being used to carry a card, a slot being provided on one side of the shell, the card being located inside the slot, a pressure plate being provided inside the shell, two rolling assemblies being provided between the top of the card and the pressure plate, the rolling assemblies being used to fix the card; the rolling assembly comprising a frame, the frame being hingedly arranged on the pressure plate, a pressure wheel being provided on the frame, a plurality of springs being provided between the top of the frame and the pressure plate, the springs being used to control the downward movement of the frame, thereby squeezing the card.

[0021] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Refer to the instruction manual Figures 1 to 5 A manual card reading device for a gas station includes a shell 1, which is used to carry a card 2. A slot is provided on one side of the shell 1, and the card 2 is located inside the slot. A pressure plate 4 is provided inside the shell 1, and two rolling assemblies 3 are provided above the card 2 and between the pressure plate 4. The rolling assembly 3 is used to fix the card 2; the rolling assembly 3 includes a frame 31, which is hingedly set on the pressure plate 4, and a pressure wheel 32 is provided on the frame 31. A plurality of springs 33 are provided between the top of the frame 31 and the pressure plate 4, and the springs 33 are used to control the frame 31 to move downward, thereby squeezing the card 2.

[0023] In the above embodiment, two rolling assemblies 3 are provided, which can ensure that the contact between the chip on the card 2 and the contact head 6 is more uniform, reducing the problem of poor contact; it can prevent the card 2 from loosening, ensuring that the chip on the card 2 is in close contact with the contact head 6; since a spring 33 is installed on the rolling assembly 3, the rolling assembly 3 is an adjustable structure, which can adapt to cards 2 of different thicknesses, ensuring that various cards 2 can have good contact with the contact head 6.

[0024] It should be noted that when the card 2 is inserted into the slot, the card 2 contacts the pressure wheel 32 and slides along the pressure wheel 32 toward the inside of the shell 1, forming an upward thrust on the pressure wheel 32. The pressure wheel 32 drives the frame 31 to move upward, compressing the spring 33. When the card 2 completely enters the inside of the shell 1, the elasticity of the spring 33 pushes the frame 31, so that the pressure wheel 32 is in close contact with the surface of the card 2, and then the card 2 can be squeezed downward, so that the lower surface of the card 2 is tightly fitted with the inner wall of the shell 1, which can avoid the formation of a gap between the card 2 and the shell 1.

[0025] Furthermore, a mounting cavity is provided on the surface of the two frames 31 , and the pressing wheel 32 is rotatably arranged inside the mounting cavity, and is provided in plurality.

[0026] It should be noted that since there are multiple holes on the surface of the pressure plate 4 and the top of the spring 33 is connected to the inner wall of the hole, when the card 2 completely enters the shell 1, the frame 31 is parallel to the card 2, and the size of the pressure wheel 32 on the frame 31 is larger than the width of the frame 31, that is, the multiple pressure wheels 32 on the frame 31 can fully contact the card 2.

[0027] The multiple pressing wheels 32 can not only balance the force range of the card 2 , but also form a certain resistance to the card 2 to prevent the card 2 from sliding from the inside of the housing 1 , thereby increasing the stability of the card 2 .

[0028] Further, refer to the instructions attached Figure 2 and Figure 4 The housing 1 includes an upper plate 11 and a lower plate 12, and the upper plate 11 and the lower plate 12 are fixed.

[0029] It should be noted that since both the upper plate 11 and the lower plate 12 are made of glass fiber reinforced PC material through injection molding, and the advantages of glass fiber reinforced PC material are good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, it can enhance the performance of the shell 1.

[0030] Because the upper plate 11 and the lower plate 12 are fixedly connected by bolts, not only the tightness between the upper plate 11 and the lower plate 12 is increased and loosening is prevented, but also when the interior of the shell 1 needs to be cleaned, the bolts can be removed to separate the upper plate 11 and the lower plate 12, thereby processing the shell 1, which is simple to operate.

[0031] Furthermore, the pressing plate 4 is arranged on the upper plate 11 , and a plurality of clamping blocks 5 are provided between the side surface of the pressing plate 4 and the upper plate 11 .

[0032] It should be noted that the pressure plate 4 is fixed to the upper plate 11 by the clamping block 5, so that the pressure plate 4 can be quickly installed and disassembled without the use of tools, thereby improving the convenience of operation, and the clamping block 5 can provide a stable fixing force to ensure that the pressure plate 4 will not loosen or shift during use.

[0033] Furthermore, a groove is provided on the lower plate 12 , and a plurality of contact heads 6 are provided inside the groove.

[0034] It should be noted that the contact heads 6 are arranged in double rows, with four in each row, which not only reduces signal attenuation and distortion, ensures data integrity and accuracy, but also disperses contact pressure, reduces wear on each contact head 6, and extends the service life of the card reader and card 2.

[0035] Further, refer to the instructions attached Figure 4 and Figure 5 A limit block 7 is movably provided on the lower plate 12, a screw 8 is provided inside the lower plate 12, the limit block 7 is threadedly sleeved on the screw 8, a turntable 9 is connected to the bottom of the screw 8, the turntable 9 is movably set on the surface of the lower plate 12, and a plurality of rotating rods 10 are provided at the bottom of the turntable 9.

[0036] It should be noted that after the card 2 is placed in the housing 1, the rotating rod 10, the electric turntable 9 and the screw 8 rotate to move the limit block 7 out from the inside of the lower plate 12, forming a protrusion, which can block the card 2 and prevent the card 2 from being accidentally pulled out, thereby improving the safety of the card 2. Conversely, the limit block 7 is retracted into the inside of the lower plate 12 to release the restriction on the card 2 and the card 2 can be taken out.

[0037] A limiting ring is provided on the outside of the turntable 9 . When the turntable 9 rotates, the limiting ring is driven to rotate synchronously, thereby limiting the turntable 9 and preventing the turntable 9 from falling off the lower plate 12 .

[0038] Working Principle: First, insert the card 2 into the slot on the housing 1 and push the card 2 to move continuously, so that the card 2 contacts the pressure wheel 32 on the frame 31. The contact between the card 2 and the pressure wheel 32 generates friction, causing the pressure wheel 32 to rotate inside the frame 31, causing the card 2 to slide along the pressure wheel 32. The card 2 exerts a certain pushing force on the pressure wheel 32, causing the pressure wheel 32 to drive the frame 31 upward, causing the spring 33 to be compressed.

[0039] When the card 2 is completely inserted into the shell 1, the frame 31 is in a parallel state. Through the elasticity of the spring 33, not only can the pressure wheel 32 fit tightly with the surface of the card 2, forming pressure on the card 2, so that the chip on the card 2 is in close contact with the contact head 6, but it can also form a certain resistance to the card 2, preventing the card 2 from falling off from the shell 1, thereby improving the stability of the card 2.

[0040] Then, the rotating rod 10 drives the turntable 9 and the screw 8 to rotate. Since the limit block 7 is threadedly connected to the screw 8, when the screw 8 rotates, the limit block 7 can move upward along the screw 8 and be pushed out from the inside of the lower plate 12 to limit the card 2. This not only prevents the card 2 from being accidentally ejected by the machine, but also locks the inside of the card 2 to prevent the card 2 from being accidentally pulled out, further increasing the stability of the card 2.

[0041] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
