DETAILED DESCRIPTION
[0027] like Figures 1 to 6As shown, the present invention discloses a dust-proof and moisture-proof dry-type transformer, comprising a transformer body 1 and a housing 2 sealed outside the transformer body 1. The transformer body 1 utilizes existing mature equipment, and the housing 2 is provided with interfaces for connecting devices, facilitating the connection of cables, etc. The front touch screen is spaced a certain distance from the housing 2.
[0028] As an improvement to the embodiment of the present invention, sealing cotton is filled between the inner side of the transformer body 1 and the housing 2. This sealing cotton prevents the generation and accumulation of static electricity, thereby reducing the risk of explosion. By using fireproof materials, it also provides a certain degree of fire protection. The sealing cotton is placed outside the touch screen to avoid interference with the touch screen. The use of sealing cotton also provides a buffer between the housing 2 and the transformer body 1, further protecting the transformer body 1.
[0029] The device is square in shape, with a square window 3 on one side of the housing 2. A transparent panel 4 is installed in the window 3, through which the display screen inside the housing 2 can be observed. The transparent panel 4 corresponds to the side of the transformer body 1 where the touch screen is located, that is, the touch screen is located on the side where the transparent panel 4 is located.
[0030] In order to facilitate the control of the touch screen, a first control button 5 is installed on the transparent panel 4 of the present invention. The first control button 5 can slide on the transparent panel 4, and by operating the first control button 5, it can act on the touch screen without causing any obstruction. Specifically, the first control button 5 disclosed in the present invention includes an inner slider 6 and an outer slider 7. The inner slider 6 is slidably installed on the inner side of the transparent panel 4. The inner slider 6 is made of a material that can wake up the touch screen. The outer slider 7 is slidably installed on the outer side of the transparent panel 4. The outer slider 7 is magnetically connected to the inner slider, and the inner slider 6 is separated from the touch screen. When the outer slider 7 is moved under human control, the inner slider 6 can also move to a corresponding position under the action of magnetism, thereby meeting the touch control needs of different positions.
[0031] By pressing the outer slider 7 from the outside inward, the inner slider 6 can be brought into contact with the touch screen to enable touch control. By installing the first control button 5, the present invention can replace direct touch control of the touch screen, thereby truly realizing the touch screen protection function, without affecting the normal use of the device, and can provide comprehensive and multi-level protection.
[0032] In this embodiment, an electromagnet 8 is installed on the inner side of the outer slider 7 , and the electromagnet 8 is connected to the power supply and the controller through a switch. A permanent magnet 9 corresponding to the electromagnet 8 is installed in the inner slider 6 .
[0033] In this embodiment, to facilitate the swiping operation, the present invention provides a plurality of sliding holes 10 along the circumference of the inner slider 6. The inner slider 6 is cylindrical, and the axes of the sliding holes 10 are parallel to the axis of the inner slider 6. There are nine sliding holes 10, evenly distributed around the center of the inner slider 6. The openings of the sliding holes 10 face the touch screen, allowing the touch posts 11 to pass through.
[0034] Specifically, a touch column 11 is slidably installed in the sliding hole 10, and the touch column 11 can be displaced along the axial direction of the sliding hole 10. A permanent magnet 9 is installed on the inner side of each touch column 11, and an elastic support device is connected between the touch column 11 and the bottom of the sliding hole 10. The elastic support device is used to provide an outward elastic support force for the touch column 11; correspondingly, a groove 13 is opened on the outer side of the outer sliding block 7, and a plurality of buttons 14 are evenly distributed on the peripheral wall of the groove 13 along the circumference of the groove 13. Switches are installed in a one-to-one correspondence with the buttons 14, and the permanent magnets 9 and the electromagnets 8 are in a one-to-one correspondence. The buttons 14 are slidably installed in the sliding grooves opened on the peripheral wall of the groove 13. When the buttons 14 slide radially outward, they can touch the switch, and the controller controls the electromagnet 8 to disconnect.
[0035] During operation, when an operator wishes to swipe in the 3 o'clock direction, their finger touches the button 14 in the corresponding direction. The corresponding electromagnet 8 at the 3 o'clock position breaks, and the touch post 11 extends outward from the slide hole 10 until the outer end of the touch post 11 contacts the touch screen, allowing for convenient control of the touch screen. By providing multiple sets of touch posts 11 corresponding to buttons 14 on a circumference, the present invention ensures that the direction of contact between the finger and the button 14 corresponds to the direction of contact between the touch post 11 and the touch screen, enabling more precise control operations.
[0036] In this embodiment, adjacent electromagnets 8 are separated by a magnetic isolation plate to prevent the two adjacent sets of electromagnets 8 from interfering with the corresponding permanent magnets 9, thereby providing more accurate control of the permanent magnets 9. In other embodiments, the outer slider 7 itself can also be made of a magnetic isolation material to achieve the above-mentioned function. However, such materials are relatively difficult to manufacture, which may increase manufacturing and material costs.
[0037] In this embodiment, a second control button 15 is mounted on the transparent panel 4. The structure of the second control button 15 is the same as that of the first control button 5. The outer button 14 is connected to the housing 2 via a cable 16. By installing the second control button 15, the present invention can implement two-finger touch operation, enabling more touch functions without affecting the protection capability.
[0038] In this embodiment, the inner side of the shell 2 is filled with inert gas, which can achieve better fire and moisture prevention effects.
[0039] In this embodiment, elastic buffer rods 17 are installed around the periphery of the transformer body 1 and between the housing 2. One end of the elastic buffer rod 17 is connected to the housing 2, and the other end of the elastic buffer rod 17 slidably engages with a slide rail 18 installed on the outside of the transformer body 1. By providing the elastic buffer rods 17, the present invention enables the transformer body 1 to be slidably disposed within the housing 2. When the housing 2 is subjected to severe vibration, relative displacement between the housing 2 and the transformer body 1 may occur. At this time, the elastic buffer rods 17 can buffer the transformer body 1, reducing the impact of the vibration on the transformer body 1 and thus providing a protective effect.
[0040] Specifically, the elastic buffer rod 17 of the present invention includes an inner rod 19, a damping spring 20, an outer rod 21, and a limit plate 22. One end of the inner rod 19 is fixedly connected to the housing 2, and the other end of the inner rod 19 is slidably disposed within the outer rod 21. The damping spring 20 is connected between the inner rod 19 and the outer rod 21. The inner end of the outer rod 21 is fixedly connected to the limit plate 22, and the limit plate 22 is slidably mounted within the guide rail. This arrangement does not affect the movement of the transformer body 1 in two degrees of freedom, while being able to provide buffering in both directions.
[0041] In this embodiment, the outer end of the inner rod 19 extends from the housing 2. The inner rod 19 is made of metal material, which can eliminate the accumulation of static electricity inside the transformer body 1 to a certain extent and play a better protective role.
[0042] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
