Description

TECHNICAL FIELD

[0001] The utility model relates to button technical field, especially is a kind of embedded self-fixing theftproof isolation type permanent magnet shielding directional magnetic induction button. BACKGROUND

[0002] In the traditional button application field, the mechanical button structure is widely used for a long time.This mechanical button structure gradually exposes a series of significant problems in actual use process, seriously affects its use effect and application range.

[0003] 1.Life short problem

[0004] Mechanical button relies on the physical contact between mechanical components to realize function.Under the frequent pressing operation, for example in some high-frequency button using equipment, such as automatic ticket vending machine, elevator button control panel, industrial control equipment and other scenes, the spring, contact and other key components inside mechanical button are easy to wear.Spring after several times of stretching, its elastic coefficient will change, leading to the decline of rebound performance, influence button's touch and reset function.The frequent friction between contacts can cause surface wear, increase contact resistance, and in severe cases, contact failure can occur, resulting in button failure.This life problem caused by mechanical wear not only increases the equipment maintenance cost and the frequency of replacing button, but also may adversely affect the normal operation of equipment, and brings inconvenience to users.

[0005] 2.Installation efficiency slow problem

[0006] The installation of mechanical button usually needs complex steps.Installation personnel need to accurately align the installation position of button, to ensure that it is accurately connected with the internal circuit of equipment.Moreover, in the installation process, it may be necessary to use a variety of tools, such as screwdriver, wrench, etc., to fix button and its related mechanical structure and wiring.For some large-scale production line equipment assembly, or the scene that needs to install a large number of buttons quickly, such as access control system button installation in large building, this complex installation process will greatly reduce the installation efficiency, increase labor cost and time cost, and delay the progress of the whole production or installation project.

[0007] 3.Not support theftproof and anti-disassembly problem

[0008] In many application scenarios, the device where the button is located has high security requirements. For example, in some financial self-service devices, security system control buttons, and other fields, mechanical buttons are easily disassembled or damaged by criminals. Due to the openness of the mechanical structure, it can be disassembled with simple tools, thereby possibly obtaining information inside the device or damaging the normal operation of the device, causing serious security risks and economic losses. Moreover, there is currently a lack of effective anti-theft and anti-disassembly solutions for mechanical buttons on the market, which cannot meet the needs of use environments with high security requirements.

[0009] In summary, these defects of the mechanical button structure have become a bottleneck for further development in the related field. Therefore, there is an urgent need for a new button technology to overcome the above problems to meet the requirements of modern devices for high reliability, high installation efficiency, and high security of buttons. The embedded self-fixing anti-theft isolated permanent magnetic shielding directional magnetic induction button provided by the present application aims to solve these long-standing problems of traditional mechanical buttons. Utility model content

[0010] The embedded self-fixing anti-theft isolated permanent magnetic shielding directional magnetic induction button of the present application aims to solve these long-standing problems of traditional mechanical buttons.

[0011] To achieve the above-mentioned purpose, the present application is implemented by the following technical solution: an embedded self-fixing anti-theft isolated permanent magnetic shielding directional magnetic induction button, comprising a button fixed shell and a movable inner core; the movable inner core is resiliently installed on the button fixed shell through an elastic component; wherein: a shielding member is arranged on the inner wall of the lower cavity of the movable inner core; a neodymium magnet is embedded in the center of the lower cavity of the movable inner core through the shielding member; an embedded reverse tooth is provided on the button fixed shell; the button fixed shell is installed on the control panel through the embedded reverse tooth; a vacuum two-way magnetic force switch is provided below the embedded reverse tooth; the magnetic field generated by the neodymium magnet is isolated by the shielding member, and the neodymium magnet directionally attracts the vacuum two-way magnetic force switch to make it act.

[0012] Further, as an improvement of the technical solution of the present application, the shielding member is a ferrite shielding glue.

[0013] Further, as an improvement of the technical solution of the present application, a nitrile rubber ring is provided between the button fixed shell and the embedded reverse tooth.

[0014] Further, the elastic component is a spring.

[0015] The utility model has the following beneficial effects:

[0016] I. Improve the service life of the button

[0017] Reduce wear and tear

[0018] The traditional mechanical button is prone to wear and tear due to frequent friction of mechanical parts, while the button of the utility model adopts a magnetic induction principle. The movable inner core and the button fixed shell are connected by an elastic component (such as a spring) to realize a springback function, but there is no direct friction of mechanical contacts during operation. This non-contact design greatly reduces the wear and tear of components caused by friction, thereby effectively prolonging the service life of the button and reducing the cost and maintenance workload caused by frequent replacement of the button due to damage.

[0019] Stable performance

[0020] The internal magnetic field is stable and not affected by external ordinary mechanical factors by using permanent magnetic shielding directional magnetic guiding technology. Compared with the performance fluctuations that may occur in traditional mechanical buttons in complex environments (such as dust and humidity changes), the button can maintain a stable working state for a long time, further ensuring its service life and reliability.

[0021] II. Improve installation efficiency

[0022] Convenient installation structure

[0023] The embedded reverse tooth structure provided on the button fixed shell provides convenience for installation. This design allows the button to be installed on the control panel without the need for complex alignment and excessive tool operation. The installer only needs to rotate the button fixed shell into the corresponding position of the control panel through the embedded reverse tooth, greatly simplifying the installation process and improving the installation speed. It is especially suitable for large-scale installation scenarios, which can effectively shorten the installation period and reduce labor costs.

[0024] III. Enhance anti-theft and anti-disassembly performance

[0025] Unique anti-theft design

[0026] The embedded reverse tooth design itself increases the difficulty of disassembly. Unlike traditional mechanical buttons that can be easily disassembled by ordinary tools, this special installation structure requires specific tools and operation methods to disassemble, forming the first obstacle to lawbreakers.

[0027] The vacuum bidirectional magnetic switch located below the embedded reverse tooth only acts under the specific magnetic field generated by the neodymium magnet after isolation by the shielding member. This unique design prevents the internal circuit or related functions of the button from being triggered during abnormal disassembly, effectively preventing information acquisition or device damage after illegal disassembly, and ensuring the safety of the device and system.

[0028] The nitrile rubber ring not only enhances the sealing between the button fixing shell and the embedded reverse tooth, but also prevents external tools from easily inserting for disassembly to some extent, further improving the anti-theft and anti-disassembly performance.

[0029] Four, optimize magnetic field utilization and shielding effect

[0030] Magnetic field directional control

[0031] By arranging a shielding member (such as a ferrite shielding glue) on the inner wall of the lower cavity of the movable inner core, the direction of the magnetic field generated by the neodymium magnet can be accurately controlled. This directional magnetic design allows the magnetic field to accurately act on the vacuum bidirectional magnetic switch, ensuring the accuracy and reliability of the button operation and avoiding interference with surrounding electronic components caused by disordered diffusion of the magnetic field.

[0032] Effective magnetic field shielding

[0033] The shielding member can effectively isolate the magnetic field of the neodymium magnet, preventing the magnetic field from having adverse effects on other electronic devices or components around it. This is particularly important in devices with high electromagnetic environment requirements, ensuring the electromagnetic compatibility and stability of the entire device system.

[0045] The utility model will be combined with the drawings and specific embodiments to be explained in detail below, here with the utility model of the illustrative embodiment and the explanation is used to explain the utility model, but not as the limitation of the utility model.

[0046] Please refer to Figures 1 to 3The utility model provides a technical scheme: a kind of embedded self-fixing theftproof isolated permanent magnet shielding directional magnetic induction button, including button fixed shell 101 and movable inner core 103;The movable inner core 103 is installed on the button fixed shell 101 by elastic component 104 reboundably;Wherein: shielding piece 106 is arranged on the lower cavity inner wall of the movable inner core 103;NdFeB 105 is embeddedly installed in the center of the lower cavity of the movable inner core 103 by the shielding piece 106;Embedded reverse tooth 102 is provided on the button fixed shell 101;The button fixed shell 101 is installed on control panel by the embedded reverse tooth 102;Vacuum bidirectional magnetic switch 108 is provided below the embedded reverse tooth 102;After the magnetic field generated by NdFeB 105 is isolated by the shielding piece 106, NdFeB 105 directional suction vacuum bidirectional magnetic switch 108 makes it act.The utility model uses permanent magnet shielding directional magnetic technology, and the effect of internal magnetic field is stable and not disturbed by external ordinary mechanical factors.Compared with the performance fluctuation that traditional mechanical button can appear in complex environment (such as dust, humidity change etc.), this button can keep stable working condition for a long time, further guarantee its life and reliability.The embedded reverse tooth 102 structure provided on button fixed shell 101 provides convenience for installation.This design makes that button is installed on control panel, without complex alignment and excessive tool operation.Installation personnel only need to spin button fixed shell 101 into the corresponding position of control panel by embedded reverse tooth 102, greatly simplify installation process, improve installation speed, especially applicable to large-scale installation scene, can effectively shorten installation period, reduce labor cost.The design of embedded reverse tooth 102 itself increases dismounting difficulty, and traditional mechanical button is different from being easily dismounted by ordinary tool, and this special installation structure needs specific tool and operation method to dismount, forms the first obstacle to lawbreaker.Vacuum bidirectional magnetic switch 108 below embedded reverse tooth 102 only acts under the action of specific magnetic field generated by NdFeB 105 after isolation by shielding piece 106.This unique design makes that when dismounting abnormally, the circuit or relevant function in button cannot be triggered, effectively prevents information acquisition or equipment damage after illegal dismounting, guarantees the safety of equipment and system.

[0047] Specifically, in the embodiment, the shielding member 106 is a ferrite shielding glue. It should be noted that by arranging the shielding member 106 (such as ferrite shielding glue) on the inner wall of the lower cavity of the movable inner core 103, the direction of the magnetic field generated by the neodymium magnet 105 can be accurately controlled. This directional magnetic guiding design enables the magnetic field to accurately act on the vacuum bidirectional magnetic switch 108, ensuring the accuracy and reliability of the button operation and avoiding the interference of the disordered diffusion of the magnetic field on the surrounding electronic elements.

The movable inner core 103 and the button fixing shell are connected by the elastic component 104 (such as a spring) to realize the springback function, but there is no direct friction of mechanical contacts during operation. This non-contact design greatly reduces the wear of components caused by friction, thereby effectively prolonging the service life of the button and reducing the cost and maintenance workload caused by frequent replacement of damaged buttons.
