Description

Technical Field

[0001] The utility model relates to the technical field of POS machines, in particular to a dust-proof POS machine. Background Art

[0002] After the POS machine reads the cardholder's magnetic stripe information on the bank card through the card reader, the POS operator inputs the transaction amount, the cardholder inputs the personal identification information, and the POS machine sends this information through the UnionPay center to the card-issuing bank system to complete the online transaction, gives information on whether it is successful or not, and prints the corresponding receipt. However, the commonly used POS machines do not have dust-proof measures. In particular, places such as the card-slot are particularly prone to accumulating dust, so that when swiping the card, the cardholder's magnetic stripe information cannot be read. Therefore, there is a kind of POS machine as follows:

[0023] The following will describe in detail a dust-proof POS machine of the present utility model in conjunction with the accompanying drawings.

[0024] As Figures 1-3 shown, an embodiment of a dust-proof POS machine of the present utility model includes a POS machine body 1 and a housing 2 provided on the side of the POS machine body 1. A card-swipe slot 3 is provided between the housing 2 and the POS machine body 1. After swiping a bank card once in the card-swipe slot 3, the POS machine body 1 can read the magnetic stripe information of the cardholder on the bank card through a card reader, and then perform subsequent operations. Among them, a fixed frame 4 is provided on the outer side of the housing 2, and a number of fixing rods 5 arranged horizontally in the axial direction are provided on the fixed frame 4. A dust-proof plate 6 for dust-proofing the card-swipe slot 3 is slidably provided on the fixing rods 5. A first spring 7 is wound around the fixing rods 5, and the first spring 7 is placed on the side of the dust-proof plate 6 away from the POS machine body 1 to apply a force to the dust-proof plate 6; when holding the bank card and swiping directly, there is no need to first slide open the dust-proof plate 6 and then swipe the card. The bank card first contacts the front side of the dust-proof plate 6, and then continues to apply force to push open the dust-proof plate 6. When swiping the card, the dust-proof plate 6 contacts the surface of the bank card, and the first spring 7 is compressed. After the card-swipe is completed, under the action of the first spring 7, the dust-proof plate 6 automatically resets to cover the card-swipe slot 3 again, achieving the dust-proof effect without extra operations.

[0025] Furthermore, a guiding member 8 for guiding the bank card before swiping is provided on the front side surface of the dust-proof plate 6. Under the action of the guiding member 8, the dust-proof plate 6 can be pushed open better before swiping the card. A wiping mechanism 9 for cleaning the surface of the bank card before swiping is provided in front of the housing 2. Under the action of the wiping mechanism 9, the surface of the bank card is cleaned first when swiping the card, and then the cleaned surface is swiped into the card-swipe slot 3. And there is no need for extra operations when swiping the card, so that the dust on the bank card cannot remain in the card-swipe slot 3, reducing the wear of the POS machine body 1. A guiding plate 10 is fixedly provided on the side of the POS machine body 1, and the guiding plate 10 is placed in front of the wiping mechanism 9. Under the action of the guiding plate 10, the bank card can be accurately swiped into the card-swipe slot 3, making it more convenient for the operator to swipe the card.

[0026] As Figures 4-7As shown, the wiping mechanism 9 includes a guide rod 901 horizontally arranged axially and fixedly provided on the fixed frame 4. A slide rod 902 is slidably provided on the guide rod 901, and the slide rod 902 slides on the guide rod 901 in a direction close to or away from the POS machine body 1. Among them, a pair of left-right arranged support rods 904 are provided at the card slot 3 in front of the housing 2. There is a groove on the side of the POS machine body 1 close to the housing 2. The left support rod 904 is fixedly provided in the groove, and the right support rod 904 is fixedly provided on the slide rod 902. The left support rod 904 is fixedly provided, and the right support rod 904 is movably provided. In addition, a second spring 903 is wound around the guide rod 901, and the second spring 903 is placed on the side of the slide rod 902 away from the housing 2 to apply a force to the slide rod 902. The wiping mechanism 9 further includes a clamping assembly and a shaft cylinder 911. The shaft cylinder 911 is detachably provided on the support rod 904 through the clamping assembly. A cleaning cotton 913 in contact with the surface of the bank card is provided on the shaft cylinder 911, and the left-right arranged cleaning cottons 913 are in contact with each other. When swiping the card, first pass the bank card through between the cleaning cottons 913. When passing through, the cleaning cottons 913 are in contact with the surface of the bank card. Because the bank card has a certain thickness, after the cleaning cottons 913 are in contact with the surface of the bank card, the right cleaning cotton 913 moves to the right, and at the same time the support rod 904 also moves to the right. The left cleaning cotton 913 remains stationary, and the second spring 903 is compressed. The cleaning cottons 913 clean the dust on the surface of the bank card, and the cleaned surface then enters the card slot 3 to prevent dust from being brought into the card slot 3 by the bank card.

[0027] As Figures 6-7As shown in the figure, the clamping assembly includes a slider 906, a telescopic rod 907 and a connecting rod 909. Both ends of the support rod 904 are internally provided with chutes 905. The slider 906 is slidably arranged in the chute 905 and is placed at the innermost side of the chute 905. One end of the connecting rod 909 is fixedly connected to the slider 906 through the telescopic rod 907, and a clamping rod 910 is provided at the other end. Among them, a third spring 908 is wound around the telescopic rod 907, and the third spring 908 is placed on the side of the slider 906 close to the connecting rod 909 to apply a force to the slider 906. After pulling the connecting rod 909, the telescopic rod 907 drives the slider 906 to slide in the chute 905, and the clamping rod 910 also moves together with the connecting rod 909. The third spring 908 is compressed. After stopping applying force to the connecting rod 909, under the action of the third spring 908, the connecting rod 909, the telescopic rod 907 and the clamping rod 910 are reset together. Embedding grooves 912 for the clamping rod 910 to be embedded are provided on both end faces of the shaft cylinder 911. The end face of the clamping rod 910 and the shape of the embedding groove 912 are both hexagonal. By pulling the connecting rod 909, the clamping rod 910 is disengaged from the embedding groove 912, and then the shaft cylinder 911 can be taken out to replace the cleaning cotton 913. After replacement, the shaft cylinder 911 is placed between the clamping rods 910 so that the clamping rods 910 are aligned with the embedding grooves 912. After stopping applying force to the connecting rod 909, the clamping rod 910 is embedded into the embedding groove 912 to clamp the shaft cylinder 911 again.

[0028] The specific working principle is as follows: When swiping the card is required, the bank card first contacts the guiding member 8 on the front side of the dust-proof plate 6, and then continues to apply force to push open the dust-proof plate 6. At the same time, the bank card passes through between the cleaning cotton 913. When passing through, both the cleaning cotton 913 and the dust-proof plate 6 are in contact with the surface of the bank card. Because the bank card has a certain thickness, after the cleaning cotton 913 contacts the surface of the bank card, the cleaning cotton 913 on the right side moves towards the right, and the cleaning cotton 913 on the left side remains stationary. The first spring 7 and the second spring 903 are compressed, and the cleaning cotton 913 cleans the dust on the surface of the bank card. The cleaned surface then enters the card swiping slot 3. After the card swiping is completed, under the action of the first spring 7, the dust-proof plate 6 automatically resets to cover the card swiping slot 3 again. Under the action of the second spring 903, the cleaning cotton 913 on the left and right sides come into contact with each other again.

[0029] In summary, it can be seen that the present utility model has the above-mentioned excellent characteristics, which can enhance the efficiency never before achieved in the prior art during use and has practicality, becoming a product with extremely high practical value.

[0030] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
