A magnetic stripe device with a new structure

Abstract

This invention relates to the field of magnetic head installation technology, specifically a magnetic stripe device with a novel structure, comprising a protective housing containing an isolation plate, an L-shaped track, and a magnetic head block. A first sliding post of the track passes through the isolation plate and is self-locked by a second elastic element, a contact block, and a limiting plate. Pushing further inward causes the contact block to drive an unlocking ring outward, unlocking the track and enabling tool-free quick installation and removal. A sealed pipe is arranged between the isolation plate and the clamping block. The first sliding post pushes a first push rod, which, driven by hydraulic oil, inserts a second push rod into the first sliding groove of the magnetic head block, with a fourth elastic element maintaining pre-pressure. The front end of the second push rod slides along a limiting groove, and the slider falls into a locking groove via a left convex groove, locking. Pushing again via a right convex groove resets and unlocks the device. Gaskets and air cushions are provided at both ends of the magnetic head block for buffering, and the magnetic head block can be replaced individually. The track can adaptively slide according to the card thickness, and the protective housing is sealed and dustproof when closed. The overall structure is compact, and locking or unlocking is completed in one insertion or removal operation, resulting in high maintenance efficiency.

Description

Technical Field

[0001] This invention relates to the field of magnetic strip installation technology, and more specifically to a magnetic strip device with a novel structure. Background Technology

[0002] With the widespread adoption of financial self-service terminals, POS machines, and smart teller machines, magnetic stripe / chip hybrid card reading modules have become core components. Traditional magnetic head assemblies generally use a rigid fixing method with screws and plastic clips, requiring multiple people and numerous tools for assembly, resulting in a slow cycle time. When repairing or replacing magnetic blocks or cleaning the magnetic head, the entire mechanism must be disassembled, which can easily cause wire pulling, solder pad detachment, and long downtime. At the same time, the thickness tolerance of cards on the market is large (0.68–0.84 mm), becoming brittle in low winter temperatures and softening in high summer temperatures. The rigid track cannot compensate in real time, resulting in a high rate of complaints about "thin cards not being able to be read and thick cards not being able to be inserted." On the other hand, the trend of equipment miniaturization has compressed the internal space to the millimeter level, leaving less than 5 mm of operating window for assembly fingers and screwdrivers, pushing the traditional structure to its limits.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example

[0034] Reference Figures 1-8 This is the first embodiment of the present invention. Specifically, the installation component 1 includes a protective shell 11, an isolation plate 111 disposed inside the protective shell 11, a track 12 slidably connected to the protective shell 11, a first sliding post 121 disposed on the outer wall of the track 12 that can penetrate the isolation plate 111, a first elastic member 13 disposed on the outer wall of the isolation plate 111, a limiting plate 14 disposed at the other end of the first elastic member 13, a second elastic member 15 disposed inside the first sliding post 121, and an abutment block 16, wherein the outer wall of the abutment block 16 is provided with a first inclined surface 161, and an unlocking ring 17 disposed inside the protective shell 11.

[0035] The connecting component 2 includes a pipe 21 located inside the protective shell 11, a first push rod 22 located at one end of the pipe 21 near the release ring 17, a second push rod 23 connected to the other end of the pipe 21, a magnetic head block 24 located inside the protective shell 11, and a first slide groove 241 located on the outer wall of the magnetic head block 24 for the second push rod 23 to slide.

[0036] The protective shell 11 houses the magnetic head, interactive chip, printing equipment, etc. An opening is formed on the side of the protective shell 11, extending inward to the isolation plate 111. A track 12, L-shaped in structure, is slidably mounted at this opening, its upward extension forming a channel for sliding cards such as bank cards and membership cards along the outer wall of the protective shell 11. A first sliding post 121 is fixedly mounted on the side of the track 12 near the isolation plate 111, allowing the first sliding post 121 to pass through the isolation plate 111. The first sliding post 121 extends beyond the isolation plate 111. In this part, a second elastic element 15, which is a compression spring, is fixedly installed inside. A contact block 16 is fixedly connected to one end of the second elastic element 15 near the outside. A first inclined surface 161 is provided on the side of the contact block 16 near the release ring 17. Simultaneously, a first elastic element 13, also a compression spring, is fixedly installed on the side of the isolation plate 111 near the inside of the protective shell 11. A limiting plate 14 is fixedly connected to the other end of the first elastic element 13. The advantage of this design is that when the track 12 is pushed inward, the first... A sliding post 121 passes through the isolation plate 111. During this process, the first inclined surface 161 of the outer wall of the contact block 16 slides along the inner wall of the limiting plate 14, and the contact block 16 slides inward. After passing through the isolation plate 111, the second elastic element 15 pushes out the contact block 16, and the contact block 16 is stuck on the back of the limiting plate 14. At the same time, a release ring 17 is slidably provided inside the protective shell 11. The release ring 17 is a ring structure. When it is necessary to remove the installation, the track 12 is pushed inward, and the first sliding post 121 on the outer wall of the track 12 is pushed inward. The contact block 16 slides along the inner wall into the release ring. Inside the limiting ring 17, the second elastic element 15 pushes the abutment block 16 outward. The abutment block 16 abuts against the inner wall of the releasing ring 17, increasing its pressure. Using friction, the releasing ring 17 moves outward. When the releasing ring 17 contacts the limiting plate 14, the releasing ring 17 begins to disengage, and the abutment block 16 enters the inner wall of the limiting plate 14. Subsequently, it slides out of the protective shell 11, realizing the rapid disassembly of the track 12. At the same time, when the bank card slides along the inside of the track 12, the bank card can push the track 12 outward, and the abutment block 16 squeezes the limiting plate 14, adapting to the thickness of the card.

[0037] Meanwhile, a pipe 21 is provided inside the protective shell 11 for the flow of liquid oil. One end of the pipe 21 is connected to the first sliding column 121, which can push the first push rod 22. The first push rod 22 slides inside the pipe 21, and the end of the first push rod 22 near the inside of the pipe 21 is fitted with a piston for sealing. The other end of the pipe 21 is also provided with a second push rod 23. The end of the pipe 21 where the second push rod 23 is located is respectively set on both sides of the magnetic head block 24. The magnetic head block 24 has a first sliding groove 241 corresponding to the position of the pipe 21. When the first sliding column 121 is pushed inward, it will push the first push rod 22. The first push rod 22 pushes the liquid oil inside the pipe 21, and the liquid oil pushes the second push rod 23, which enters the first sliding groove 241.

[0038] During installation, the magnetic head block 24 is first pushed into the protective shell 11, then the track 12 is pushed. The first sliding post 121 on the outer wall of the track 12 pushes the first push rod 22, and then the second push rod 23 enters the first sliding groove 241. The magnetic head block 24, track 12, and protective shell 11 are then installed. The advantage of this design is that it facilitates subsequent installation. Furthermore, the track 12 can slide, and when not in use, it can close the protective shell 11, reducing the impact of external factors on the magnetic head and internal chip. During use, the width can be adjusted according to the card thickness. Example

[0039] Reference Figures 1-8 This is the second embodiment of the present invention. Specifically, a second inclined surface 122 is provided at one end of the inner side of the track 12.

[0040] The inner wall of the track 12 near the protective shell 11 has a second inclined surface 122. The advantage of this design is that it makes it easier for the card to slide into the track 12.

[0041] Preferably, the isolation plate 111 is recessed inward along the outer wall of the protective shell 11 to form a first movable channel 112 for the track 12 to slide. The isolation plate 111 is provided with a first through hole 113 that connects to the first movable channel 112. The inner wall of the first through hole 113 is provided with a third inclined surface 1131.

[0042] The first active channel 112 is formed by the inward indentation of the protective shell 11, and the bottom plate near the inside is called the isolation plate 111. The magnetic head block 24 and the track 12 are both installed inside the first active channel 112. At the same time, the first through hole 113 penetrates the isolation plate 111. The inner wall of the first through hole 113 near the inside of the protective shell 11 is chamfered to form a third inclined surface 1131. When the first sliding column 121 slides outward, the contact block 16 slides along the surface of the third inclined surface 1131 and then disengages from the isolation plate 111, thus achieving disassembly.

[0043] Preferably, the outer wall of the isolation plate 111 is provided with a sleeve 114, and the pipe 21 passes through the sleeve 114;

[0044] The release ring 17 is disposed inside the sleeve 114, and the inner wall of the release ring 17 near the limiting plate 14 is provided with a fourth inclined surface 171.

[0045] A sleeve 114 is fixedly installed on the outer wall of the isolation plate 111 to provide a sliding channel for the release ring 17 and the limiting plate 14. At the same time, the pipe 21 is connected to the inside of the sleeve 114. The inner wall of the release ring 17 near the contact block 16 is chamfered to form a fourth inclined surface 171, which facilitates the contact block 16 to enter the interior of the release ring 17.

[0046] Preferably, the inner wall of the protective shell 11 is provided with a clamping block 115, and the end of the pipe 21 away from the release ring 17 passes through the clamping block 115.

[0047] Clamping blocks 115 are provided on both sides of the magnetic head block 24. The clamping blocks 115 are fixed inside the protective shell 11, forming a channel for the magnetic head block 24 to slide. At the same time, they provide support for the installation of the pipe 21, which passes through the clamping blocks 115 and is distributed on both sides of the magnetic head block 24.

[0048] Preferably, a magnetic block A is detachably provided inside the magnetic head block 24;

[0049] The magnetic head block 24 has outwardly raised pads 243 at both ends, and a third elastic element 25 is provided between the pads 243 and the clamping block 115.

[0050] The magnetic head block 24 contains a magnetic block A, which is existing technology and is used to collect card information. In this design, magnetic block A is connected to other electronic devices inside the protective shell 11 by wires. This is existing technology and will not be described in detail. The magnetic block A and the magnetic head block 24 can be installed using screws, allowing for detachable connection between magnetic block A and the protective shell 11. The advantage of this design is that if magnetic block A is damaged, it can be directly removed without disassembling the protective shell 11. Then, the wires can be reconnected to a new magnetic block A, avoiding complete disassembly and potential damage to other electronic components.

[0051] Meanwhile, shims 243 are provided at both ends of the magnetic head block 24, and a third elastic element 25 is provided between the shims 243 and the clamping block 115. The third elastic element 25 is an air bladder. The advantage of this design is that it can play a role in buffering and positioning when installing the magnetic head block 24.

[0052] Preferably, the first groove 241 is provided with a fourth elastic element 26.

[0053] The first slide groove 241 has a fourth elastic element 26 fixedly installed at the bottom. The fourth elastic element 26 is a compression spring. When the second push rod 23 slides into the first slide groove 241, it will squeeze the fourth elastic element 26. When the track 12 is disassembled, the fourth elastic element 26 will reset the first push rod 22 and the second push rod 23 for easy reuse.

[0054] In summary, during use, the magnetic head block 24 is first pushed inward along the first active channel 112 and enters between the clamping blocks 115. Then, the track 12 is pushed inward, and the first sliding column 121 inside the track 12 starts to push the first push rod 22, which then drives the second push rod 23 into the first sliding groove 241, while simultaneously squeezing the fourth elastic member 26. Example

[0055] Reference Figures 1-8 In the third embodiment of the present invention, specifically: the rotating rod 27 on the outer wall of the second push rod 23 has a limiting groove 242 on the inner wall of the first sliding groove 241, and a slider that can slide along the inside of the limiting groove 242 is provided on the outer wall of the rotating rod 27.

[0056] A limiting groove 242 is provided inside the first slide groove 241. The limiting groove 242 restricts the sliding of the rotating rod 27 along the inside of the first slide groove 241. The rotating rod 27 is rotatably connected to the second push rod 23, and the two can be connected by a key-groove structure. An annular groove is provided on the inner wall of the rotating rod 27, and a key is provided on the outer wall of the second push rod 23 to achieve the rotatable connection. This is prior art and will not be described in detail. At the same time, there is a slider on the outer wall of the rotating rod 27 that can slide along the inside of the limiting groove 242.

[0057] Preferably, the limiting groove 242 forms a limiting platform 28;

[0058] The outer wall of the limiting platform 28 is recessed to form a groove 281;

[0059] The limiting groove 242 includes a left protrusion 2421 and a right protrusion 2422;

[0060] The inner wall of the first slide groove 241 is provided with a vertical groove 244, and the vertical groove 244 is connected to the limiting groove 242.

[0061] The limiting groove 242 is recessed inward along the inner wall of the first sliding groove 241 to form a limiting platform 28. The limiting platform 28 forms a hook groove 281 at the bottom of the first sliding groove 241. A left convex groove 2421 and a right convex groove 2422 are provided on the left and right sides of the hook groove 281. The two convex grooves are characterized by their relatively large width; when the slider passes through this area, it will slide downwards and will not slide back. A vertical groove 244 is connected to the end of the limiting groove 242 near the second push rod 23. The vertical groove 244 connects to the outside of the first sliding groove 241, facilitating the slider's entry from the clamping block 115 into the interior of the first sliding groove 241.

[0062] Preferably, the inner wall of the first slide groove 241 is provided with a horn groove 245, and the horn groove 245 is connected to the limiting groove 242 through a vertical groove 244.

[0063] The vertical groove 244 expands outward to form a horn groove 245, and includes two horn grooves 245, vertical groove 244, and limiting groove 242 inside the first sliding groove 241. The two ends of the horn groove 245 are connected. The advantage of this design is that it does not need to consider the possible offset that may occur during the sliding of the rotating rod 27, which would prevent the rotating rod 27 from smoothly entering the limiting groove 242.

[0064] As the first sliding column 121 pushes the second push rod 23 into the first sliding groove 241, the slider on the outer wall of the rotating rod 27 enters the vertical groove 244 along the inner wall of the horn groove 245 and then into the limiting groove 242. It then slides along the inside and reaches the left convex groove 2421. After that, it stops pushing the track 12 and the fourth elastic element 26 pushes the rotating rod 27 outward. The slider on the outer wall of the rotating rod 27 enters the hook groove 281, realizing the connection between the clamping block 115 and the magnetic head block 24. Example

[0065] Reference Figures 1-8 In the fourth embodiment of the present invention, specifically: the release ring 17 is fixedly connected to the first push rod 22. The advantage of this design is that when the first sliding column 121 pushes the first push rod 22, there is no need to worry about the contact block 16 entering the release ring 17 and causing the release ring 17 to slide. Subsequently, the contact block 16 disengages from the release ring 17 and then enters the limiting plate 14, causing the track 12 to disengage. The sliding of the release ring 17 is limited by hydraulic pressure, that is, the rotating rod 27 is limited in the hook groove 281, the first push rod 22 is limited by hydraulic pressure, and the limiting plate 14 is limited by hydraulic pressure. When disassembly is required, the first sliding column 121 is pushed inward, and the first sliding column 121 pushes the first push rod 22 again. The rotating rod 27 on the outer wall of the second push rod 23 moves inward, and then the slider on the outer wall of the rotating rod 27 slides along the inside of the limiting groove 242, returns to the vertical groove 244 along the right protrusion 2422, and then slides out of the limiting groove 242, releasing the restriction.
