Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of card tooling fixtures, and particularly relates to a card reading mechanism. Background Technique
[0002] There are many types of card reading mechanisms. Generally, the principle is to read data by means of electromagnetic induction on the chip of the card, which is widely used in various cards such as water cards, bus cards and savings cards. Generally, the data can be read directly by placing the card.
[0003] However, in some special fields, such as gas, fuel, gas stations, etc., due to industry regulations, in order to avoid fire and explosion hazards, it is not allowed to use radio frequency cards, so only ordinary chip cards can be used. After inserting the card, it takes even about 1 minute to import the data, which is a relatively long time. Sometimes, due to contact problems, the data will not be displayed, and it is necessary to insert and remove the card many times, or the operator manually presses it to increase the contact distance, which makes the operation extremely inconvenient. For example, taking a pre-paid gas card as an example, this type of card is suitable for an IC card gas meter and can only be recharged by plugging and unplugging. If the card is plugged and unplugged too frequently during the recharge and card swiping process, it will accelerate the wear of the chip and easily cause scratches on the chip, which will reduce the sensitivity of the chip and affect the use effect. Content of the Utility Model
[0004] To overcome the above defects, the purpose of the utility model is to provide a card reading mechanism, which changes the card reading method by setting a hinged pressing cover, reduces scratches and prolongs the service life.
[0005] To achieve the above purpose, the utility model provides a card reading mechanism, including a base and a pressing cover. A limiting groove is provided on the base. One end of the pressing cover is hinged to the base, and a guide rod adapted to the limiting groove is installed at the other end. The base is provided with a main board accommodating cavity, and the main board accommodating cavity is close to the hinged end of the pressing cover. A plurality of main board top pins are arranged in the main board accommodating cavity. A display screen avoiding groove is provided on the pressing cover, and the display screen avoiding groove is located above the main board accommodating cavity. A supporting plate is further provided on the pressing cover, and an accommodating groove for placing the card body is formed between the supporting plate and the pressing cover, and the card body is clamped between the supporting plate and the pressing cover.
[0006] Preferably, a positioning pin is provided at the top of the main board accommodating cavity, and the side wall of the positioning pin abuts against one side of the pressing cover.
[0007] Preferably, a clamping mechanism for temporarily fixing and limiting the guide rod is provided in the limiting groove.
[0008] Preferably, the clamping mechanism includes a rolling bearing, a guide shaft, a compression spring and a spring plug. The base is provided with a receiving channel. The middle part of the rolling bearing is fixedly connected to one end of the guide shaft. The other end of the guide shaft abuts against the compression spring. The guide shaft slides in the receiving channel. The spring plug is fixedly connected to one end of the receiving channel by a thread. The compression spring is located in the cavity of the spring plug.
[0009] Preferably, the upper end of the guide rod is fixedly connected to the gland through a nut, and fixing grooves adapted to the rolling bearing are provided on both sides of the guide rod.
[0010] After adopting the above technical solution, the beneficial technical effects achieved by the present utility model are as follows:
[0011] 1. Since a hinged gland is provided on the base, during use, first place the main board to be placed in the main board receiving cavity of the base, then fix the card body to the gland, and by rotating the gland, it corresponds to the sensor of the reading chip on the main board. During the above process, the guide rod is inserted into the limit groove for guiding. The gland rotates in contact with the base, changing the direct plug-in type to a pressing contact type, which can avoid scratching the chip and increase the service life of the chip. Since it is in contact up and down, by adjusting the magnitude of the pressing force, the gap distance can be adjusted. The closer the fitting distance, the better the signal induction.
[0012] 2. Since the card to be read is brought into contact with the corresponding main board by rotating the gland, the volume of the card to be read is certain and the position of the main board is certain. Only a slight plugging and unplugging is required. After fixing the card to be read, then by rotating, reading can be achieved. During the above process, it can avoid chip wear or dropping caused by vigorously plugging and unplugging (the squeezing type is to ensure good contact of the chip), which can improve the service life, the operation is simpler, and it is more user-friendly to the operator.
[0013] 3. Since a limit groove for guiding is provided on the base, the upper end of the guide rod is fixedly connected to the gland, and a rolling bearing, a guide shaft and a compression spring are provided in the guide groove. By adjusting the spring plug, the pressure of the compression spring can be adjusted. When the guide rod is placed in the limit groove, the two rolling bearings can be clamped into the fixing grooves to achieve temporary fixation. The height of the gland can also be adjusted as needed. After data reading is completed, the guide rod can be directly pulled out, and the operation is extremely simple. Description of the Drawings

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0025] Referring to Figures 1 - 5 , the present utility model provides a card-reading mechanism, including a base 1 and a pressing cover 2. A limiting groove 3 is provided on the base 1. One end of the pressing cover 2 is hinged to the base 1, and a guide rod 4 adapted to the limiting groove 3 is installed at the other end. The base 1 is provided with a motherboard accommodation cavity 11, and the motherboard accommodation cavity 11 is close to the hinged end of the pressing cover 2. A plurality of motherboard top pins 12 are arranged in the motherboard accommodation cavity 11. A display screen avoidance groove 22 is provided on the pressing cover 2, and the display screen avoidance groove 22 is located above the motherboard accommodation cavity 11. A support plate 21 is further provided on the pressing cover 2, and an accommodation groove 23 for placing the card body is formed between the support plate 21 and the pressing cover 2. The card body is clamped between the support plate 21 and the pressing cover 2. The base 1 is used for support. During use, generally, the motherboard is connected to the power supply and placed in the motherboard accommodation cavity 11 of the base 1. The lower end of the motherboard is supported by four motherboard top pins 12. The pressing cover 2 and the base 1 are hinged. Generally, the materials of the base 1 and the pressing cover 2 are preferably nylon materials or synthetic plastics, which can be insulated to prevent demagnetization. First, place the card body in the accommodation groove 23 between the support plate 21 and the pressing cover 2, and the chip part should be placed outside. After rotating the pressing cover 2, the chip part of the card body fits with the induction position of the motherboard to ensure that data can be read. A display screen avoidance hole is provided on the pressing cover 2, and its function is to facilitate the placement of the card body, and another purpose is to facilitate reading.
[0026] At the top of the main board accommodation cavity 11 of the present utility model, there is a positioning pin 13, and the side wall of the positioning pin 13 abuts against one side of the gland 2. The function of the positioning pin 13 is to position the gland 2 to ensure the accuracy of its rotation position.
[0027] In the limiting groove 3 of the present utility model, there is a clamping mechanism for temporarily fixing the limiting guide rod 4. The clamping mechanism of the present utility model includes a rolling bearing 31, a guide shaft 32, a pressure spring 33 and a spring plug 34. The base 1 is provided with an accommodation channel.
