Technical Field

[0001] The present invention relates to the technical field of electronic tags, and in particular to an information updating device for electronic tags. Background Art

[0002] Electronic tags are also called radio frequency tags, transponders, and data carriers; readers are also called readout devices, scanners, readers, communicators, and reader-writers (depending on whether the electronic tags can rewrite data wirelessly). The electronic tags and readers use coupling elements to achieve spatial (contactless) coupling of radio frequency signals; in the coupling channel, energy transfer and data exchange are achieved based on the timing relationship.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In actual use, first insert the card reader body into the docking interface through the plug-in board. During insertion, the guide block and the guide groove engage with each other, so that the limit device can be driven to work, thereby releasing the positioning of the reset device. Since the guide grooves are opened at different positions on the docking interface, when the guide block on the plug-in board is not opposite to the guide groove on the docking interface, the plug-in board cannot be inserted into the docking interface of the wrong model. At the same time, when the plug-in board without a guide block is inserted into the docking interface, it will be blocked by the contact plate to prevent it from entering the interior;

[0017] 2. When the plug-in board of the same model is inserted into the interior of the docking interface, first press one end of the spring clamping plate toward the inside of the bayonet through the guide block, so that one end of the spring clamping plate is lifted out from the inside of the bayonet. At this time, when the bottom of the guide block contacts the contact plate, the contact plate can be slid downward to drive the bending plate to slide downward. In the process of the bending plate sliding downward, the push plate will drive the slider together with the spring clamping plate to slide inside the adjustment groove. When the plug-in board slides into the inner bottom surface of the docking interface, the pressing plate will be driven to slide down during the sliding process of the bending plate, so that the inclined surface of one side of the pressing plate fits with the arc surface of one side of the spring copper sheet, and the other side of the spring copper sheet is pressed toward the inside of the docking interface, so that the other side of the spring copper sheet can dock with the overlap interface on the plug-in board, thereby completing the docking transmission of electrical signals;

[0018] 3. At the same time, one end of the limit plate on the guide block will be engaged with the inside of the bayonet, thereby limiting the plug-in plate. When releasing the limit, you only need to push the dial plate toward one side of the electronic tag body to remove one side of the limit plate from the inside of the bayonet to release the limit. At this time, the bending plate is driven to slide upward under the elastic force of the first spring. In the process of the bending plate sliding upward, the spring clamping plate and the slider are pushed upward by the push plate, and the pressure plate and the contact plate are driven to slide upward at the same time. When the pressure plate slides upward, it will contact the constraints of multiple spring copper sheets, so that the spring copper sheets contact the docking interface under the action of their own elastic force. When the contact plate slides upward, it will drive the plug-in plate to slide upward, thereby facilitating the electronic tag body to be lifted upward for people to take out.

[0031] The effect achieved is that the card reader body 1 is first inserted into the docking port 7 through the plug-in plate 5. During the insertion, the guide block 11 and the guide groove 15 are engaged with each other, so that the limit device can be driven to work, thereby releasing the positioning of the reset device. Since the guide groove 15 is opened at different positions on the docking port 7, when the position of the guide block 11 on the plug-in plate 5 is not relative to the position of the guide groove 15 on the docking port 7, the plug-in plate 5 cannot be inserted into the docking port 7 of the wrong model. At the same time, when the plug-in plate 5 without the guide block 11 is inserted into the docking port 7, it will be blocked by the contact plate 23 to prevent it from entering the interior.

[0032] like Figure 2-8 As shown, the positioning device includes a limit plate 31, a mounting groove 30 is opened inside the guide block 11, a recess 32 is opened on one side of the mounting groove 30 and penetrates to the outside of the guide block 11, a dial opening 34 is opened on the top of the mounting groove 30 and penetrates to the top of the guide block 11, the limit plate 31 is installed inside the mounting groove 30, and one side of the limit plate 31 extends to the outside of the recess 32, a dial plate 33 is fixed on the top of the limit plate 31, and the top of the dial plate 33 extends to the inside of the dial opening 34, a rubber pad 12 is fixed to the inner wall of one side of the docking port 7 near the bottom edge, a side opening 6 is opened on one side of the plug-in plate 5 near the bottom edge, and the rubber pad 12 is engaged inside the side opening 6.

[0033] The effect achieved is that one end of the limit plate 31 on the guide block 11 is engaged with the inside of the bayonet 19, thereby limiting the plug-in board 5. When releasing the limit, it is only necessary to push the dial plate 33 toward the side of the electronic tag body 4 to remove one side of the limit plate 31 from the inside of the bayonet 19 to release the limit.

[0034] like Figure 2-8As shown, the reset device includes a bending plate 24, which is slidably connected to the inside of the adjusting cavity 13, a first spring 14 is fixed to the bottom of the bending plate 24 near one side edge, the bottom of the first spring 14 is fixed to the inner bottom surface of the adjusting cavity 13, and a contact plate 23 is fixed to the top of the bending plate 24 near the other side edge. A sliding opening 25 that passes through the inside of the docking interface 7 is opened on one side of the adjusting cavity 13, the contact plate 23 is slidably connected to the inside of the sliding opening 25, and one end of the contact plate 23 extends to the inside of the docking interface 7.

[0035] The effect achieved is that when resetting, the bending plate 24 is driven to slide upward under the elastic force of the first spring 14. In the process of the bending plate 24 sliding upward, the spring clamping plate 18 and the slider 17 are pushed upward by the push plate 20, and the pressure plate 29 and the contact plate 23 are driven to slide upward at the same time. When the pressure plate 29 slides upward, it will contact the constraints of multiple spring copper sheets 27, so that the spring copper sheets 27 contact the docking interface 10 under the action of their own elastic force. When the contact plate 23 slides upward, it will drive the plug-in plate 5 to slide upward, thereby facilitating the upward lifting of the electronic tag body 4 for people to take out.

[0036] like Figure 2-8 As shown, the limiting device includes a slider 17, an adjusting groove 16 is provided on the inner top surface of the adjusting cavity 13, a bayonet 19 is provided on one side inner wall of the adjusting groove 16 and penetrates into the guide groove 15, a spring clamp 18 is fixed on the top of the slider 17, one end of the spring clamp 18 is engaged in the inside of the bayonet 19, and the top and bottom corners of one side of the spring clamp 18 are inclined, a push plate 20 is fixed on the bottom of the slider 17, one side of the push plate 20 extends to the inside of the adjusting cavity 13, a constraint plate 21 is fixed on one side of the push plate 20 near the bottom edge, a through opening 22 is provided on the top of the constraint plate 21, and one end of the contact plate 23 is slidably connected to the four side inner walls of the through opening 22.

[0037] The effect achieved is that when the plug-in board 5 of the same model is inserted into the interior of the docking port 7, one end of the spring clamp 18 is first pressed toward the inside of the bayonet 19 through the guide block 11, so that one end of the spring clamp 18 is lifted out from the inside of the bayonet 19; when the plug-in board 5 without the guide block 11 is inserted into the interior of the docking port 7, it will be blocked by the contact plate 23. At this time, the bottom of the plug-in board 5 and the top of the contact plate 23 are in contact with each other, and one end of the spring clamp 18 is engaged in the inside of the bayonet 19, so the slider 17 and the push plate 20 will be limited in the inside of the adjustment groove 16, and then the contact plate 23 will be locked and fixed by the constraint plate 21, thereby preventing the contact plate 23 from sliding downward.

[0038] like Figure 2-8As shown, the overlapping device includes a plurality of spring copper sheets 27, and a plurality of openings 26 penetrating into the interior of the docking port 7 are equidistantly provided on the inner wall of one side of the inner cavity 28, and the bottoms of the plurality of spring copper sheets 27 are fixed to the inner bottom surface of the opening 26, and a pressure plate 29 is fixed to the bottom of the bending plate 24 near one side edge, and the pressure plate 29 is slidably connected to the interior of the inner cavity 28, and the bottom of the pressure plate 29 is inclined near one side edge, and both sides of the plurality of spring copper sheets 27 are arc surfaces, and the arc surfaces on one side of the plurality of spring copper sheets 27 extend to the bottom inclined surface of the pressure plate 29.

[0039] The effect achieved is that when the bending plate 24 slides down, the pressure plate 29 is driven to slide down, so that the inclined surface on one side of the pressure plate 29 fits with the arc surface on one side of the spring copper sheet 27, and the other side of the spring copper sheet 27 is pressed toward the inside of the docking port 7, so that the other side of the spring copper sheet 27 can dock with the docking port 10 on the plug-in board 5, thereby completing the docking transmission of electrical signals.

[0040] The method of using the device and the working principle are as follows: first, insert the card reader body 1 into the interior of the docking interface 7 through the plug-in plate 5. During the insertion, the guide block 11 and the guide groove 15 are engaged with each other. Since the guide groove 15 is provided at different positions on the docking interface 7, when the position of the guide block 11 on the plug-in plate 5 is not opposite to the position of the guide groove 15 on the docking interface 7, the plug-in plate 5 cannot be inserted into the interior of the docking interface 7 of the wrong model. At the same time, when the plug-in plate 5 without the guide block 11 is inserted into the interior of the docking interface 7, it will be blocked by the contact plate 23. At this time, the bottom of the plug-in plate 5 and the top of the contact plate 23 are in contact with each other, and one end of the spring clamping plate 18 is engaged with the inside of the clamping port 19. Therefore, the slider 17 and the push plate 20 will be limited inside the adjustment groove 16, and then the contact plate 23 will be locked and fixed by the constraint plate 21, so as to prevent the contact plate 23 from sliding downward. When the plug-in plate 5 of the same model is inserted into the interior of the docking port 7, firstly, one end of the spring clamp 18 is pressed toward the inner side of the bayonet 19 through the guide block 11, so that one end of the spring clamp 18 is lifted out from the inside of the bayonet 19. At this time, when the bottom of the guide block 11 contacts the contact plate 23, the contact plate 23 can be slid downward, so as to drive the bending plate 24 to slide downward. In the process of the bending plate 24 sliding downward, the slider 17 together with the spring clamp 1 will be driven by the push plate 20. 8 slides inside the adjustment groove 16, and when the plug-in plate 5 slides into the inner bottom surface of the docking interface 7, the pressing plate 29 is driven to slide down during the sliding of the bending plate 24, so that the inclined surface on one side of the pressing plate 29 fits with the arc surface on one side of the spring copper sheet 27, and the other side of the spring copper sheet 27 is pressed into the inside of the docking interface 7, so that the other side of the spring copper sheet 27 can dock with the docking interface 10 on the plug-in plate 5, thereby completing the docking transmission of the electrical signal. At the same time, one end of the limiting plate 31 located on the guide block 11 is engaged with the inside of the bayonet 19, thereby limiting the plug-in plate 5. When releasing the limit, it is only necessary to push the dial plate 33 toward the side of the electronic tag body 4. , so that one side of the limit plate 31 is removed from the inside of the bayonet 19, the limit can be released. At this time, the bending plate 24 is driven to slide upward under the elastic force of the first spring 14. In the process of the bending plate 24 sliding upward, the spring clamping plate 18 and the slider 17 are pushed upward by the push plate 20, and the pressure plate 29 and the contact plate 23 are driven to slide upward at the same time. When the pressure plate 29 slides upward, it will contact the constraints of multiple spring copper sheets 27, so that the spring copper sheets 27 contact the docking interface 10 under the action of their own elastic force. When the contact plate 23 slides upward, it will drive the plug-in plate 5 to slide upward, thereby facilitating the upward lifting of the electronic tag body 4 for people to take out.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
