Technical Field
[0001] This invention relates to the field of sealing device technology, and in particular to a sealing device with controllable opening and closing. Background Technology
[0002] With the development of technology, in pursuit of higher stability and quality, some electronic products must not be exposed to excessively strong electromagnetic waves in the surrounding environment to ensure normal operation. More and more core components of devices need to be stored in a sealed, independent space, or even a vacuum environment, before use, and only exposed when needed to ensure the condition and lifespan of critical components. Therefore, a reliable, controllable, and sealed device needs to be designed to store or protect products or equipment that require isolation from the external environment. Summary of the Invention
[0003] To address the aforementioned shortcomings in the existing technology, embodiments of the present invention provide a sealing device that can be controlled to open and close.
[0004] This invention provides a controllable opening and closing sealing device, comprising: an iron core, a conductive coil, a connector, a sealing cover, a separating rod, a first nut, a second nut, a washer, a spring, a fixing structure, an adapter cap, a ball bearing, a drive rod housing, a drive rod, a magnet, and a sealing shell;
[0005] The conductive coil is wound around the iron core, the drive rod housing is fixed inside the fixing structure, and the top of the fixing structure abuts against the spring; a mounting groove for installing a magnet is cut on one side of the drive rod, and the magnet is fixed in the pre-cut mounting groove of the drive rod; the separating rod passes through the spring and is installed at one end of the adapter cap, and the adapter cap is fitted onto the drive rod housing;
[0006] The drive rod housing has circumferential holes, and the adapter cap has holes corresponding to the drive rod housing. These holes allow the ball bearing to slide out halfway, allowing the drive rod to be inserted into the drive rod housing. The other side of the drive rod has tracks of varying depths. When the drive rod slides inside the drive rod housing, the deep and shallow tracks are switched to align with the holes in the drive rod housing. The ball bearing passes through the adapter cap and the drive rod housing and is embedded in the track of the drive rod. The ball bearing slides along the track of the drive rod.
[0007] The sealing shell is used to fix the iron core, and the iron core, the conductive coil, the drive rod and the part of the drive rod housing exposed outside the adapter cap are wrapped, allowing only the conductive coil and the wire of the connecting connector to pass through;
[0008] The number of coil turns, the input current of the conductive coil, the magnetic force of the magnet, the gap and fit between the drive rod housing and the adapter cap, the fit gap between the drive rod housing and the slider, and the fit gap between the slider and the adapter cap are preset. The electromagnetic field inside the device is adjusted to a reasonable value.
[0009] When the conductive coil is energized through the connector, the conductive coil generates magnetic poles that repel the magnet, separating the drive rod from the iron core; when the conductive coil is not energized through the connector, the magnet fixed on the drive rod attracts the iron core and makes the drive rod fit against the iron core.
[0010] In some embodiments,
[0011] When the conductive coil is not energized through the connector, the magnet pre-fixed on the drive rod will attract the iron core and make the drive rod fit against the iron core. At this time, the shallow slide on the drive rod will align with the ball bearing and push the ball bearing outward. The ball bearing will protrude halfway from the hole of the adapter cap and lock the adapter cap. The separating rod is installed on the adapter cap through the spring. The other end of the spring rests on the fixed structure. The washer is fitted on the separating rod and blocks the spring. The first nut, the second nut, and the washer are used to compress the spring downward along the separating rod and fix the sealing cover. Then, the remaining sealing cover, sealing ring, and connector are installed to form a sealing device.
[0012] When the conductive coil is energized through the connector, the conductive coil and the magnet on the drive rod generate repulsive magnetic poles, separating the drive rod from the iron core. This aligns the deep slide of the drive rod with the ball bearing. At this point, due to the absence of internal force from the drive rod, the ball bearing slides inward under the action of the spring-driven adapter cap until the adapter cap loses the force of the ball bearing. The adapter cap, the separating rod, and the sealing cap and nut fixed to the separating rod then fly out together, opening the sealing device.
[0013] In some embodiments, when the conductive coil is energized through the connector, the magnet fixed on the drive rod attracts the iron core and makes the drive rod fit against the iron core by changing the direction of the current flowing through the conductive coil.
[0014] In some embodiments, the sealing shell has an electromagnetic shielding effect, controlling the amount of electromagnetic leakage from the energized coil and magnet.
[0015] In some embodiments, there is sufficient space between the shallow slide on the drive rod and the hole in the drive rod housing.
[0016] In some embodiments, a conductive coil is connected to a connector with a wire, and the connector allows control over whether the conductive coil is energized.
[0017] In some embodiments, the separating rod has a hollow interior with internal threads and an external thread on the outside, and is of sufficient length. One side of the separating rod is connected to an adapter cap, and the other side of the separating rod extends through a sealing cap. The internal thread of the separating rod is connected to the adapter cap, and the external thread of the separating rod allows a nut to be screwed onto it.
[0018] In some embodiments, it further includes: sealing cover one, sealing cover two, sealing cover three, sealing ring one, sealing ring two, sealing ring three, and sealing ring four;
[0019] Install sealing ring two and sealing cover one onto sealing cover two in sequence, and sealing ring two is pressed to fill the gap; install sealing ring one and connector onto sealing cover two in sequence, and sealing ring one is pressed to fill the gap.
[0020] Separately attach the sealing ring three and the sealing cap through the separating rod and fix them onto the sealing cover two. The sealing ring three is pressed to fill the gap. Use nut one to press the sealing cap through the external thread on the separating rod outside the sealing ring three.
[0021] The inner shaft of the sealing cover has a thread that is not a through hole. It is screwed onto the separating rod, and the sealing ring four is passed through the separating rod. The sealing cover three is connected to the separating rod and presses the sealing ring three to fill the gap, and covers the part of the nut one and the separating rod that protrudes from the sealing cover.
[0022] In some embodiments,
[0023] The sealing cap has a through hole in the middle, through which the separation rod passes.
[0024] In some embodiments, sealing ring one, sealing ring two, sealing ring three and sealing ring four are made of rubber materials, and it is determined as needed whether it is necessary to select rubber materials that can block electromagnetic interference.
[0025] In some embodiments, sealing cover one, sealing cover two, and sealing cover three are made of different materials, and it is determined whether a material that can block electromagnetic interference needs to be selected as required.
[0026] This invention designs a sealable, electromagnetically shielded, and openable space—a controllable sealing device—to meet the needs of certain products or equipment. A magnetic field is generated by an energized coil and interacts with a pre-set magnet. By controlling the on / off state of connector 4 and triggering a spring, the sealing cover 9 is ejected. After ejection, the sealing device can be restored using the same steps, achieving both sealing and opening. This invention can be applied to products requiring electromagnetic protection or isolation from the outside environment, ensuring their performance and lifespan. Attached Figure Description

[0031] Where there is no conflict, the embodiments of the present invention and the features thereof can be combined with each other.
[0032] As used herein, the term “and / or” includes any and all combinations of one or more related enumerated entries.
[0033] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a” and “the” used herein are also intended to include the plural forms unless the context clearly indicates otherwise. It will also be understood that when the terms “comprising” and / or “made of” are used in this specification, the presence of the stated features, integrals, steps, operations, elements, and / or components is specified, but the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof is not excluded.
[0034] Unless otherwise specified, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be understood to have the meaning consistent with their meaning in the context of the relevant art and the invention, and will not be understood to have an idealized or overly formal meaning unless expressly so defined herein.
[0035] To enable those skilled in the art to better understand the technical solution, the following detailed description of a controllable opening and closing sealing device provided by the present invention is provided in conjunction with the accompanying drawings.
[0036] like Figure 1 As shown, this embodiment of the invention provides a controllable opening and closing sealing device, including: an iron core 2, a conductive coil 3, a connector 4, a sealing cover 9, a separating rod 10, a nut one 13, a nut two 14, a washer 15, a spring 16, a fixing structure 17, an adapter cap 18, a ball bearing 19, a drive rod housing 20, a drive rod 21, a magnet 22, and a sealing shell 23.
[0037] The conductive coil 3 is wound around the iron core 2. The drive rod housing 20 is fixed inside the fixing structure 17, and the top of the fixing structure 17 abuts against the spring 16. A mounting groove for installing a magnet is cut on one side of the drive rod 21, and the magnet 22 is fixed in the pre-cut mounting groove of the drive rod 21. The separating rod 10 passes through the spring 16 and is installed at one end of the adapter cap 18, and the adapter cap 18 is fitted onto the drive rod housing 20.
[0038] The drive rod housing 20 has circumferential holes, and the adapter cap 18 has a hole corresponding to the drive rod housing 20. This hole allows the spherical surface of the ball bearing 19 to slide out halfway, allowing the drive rod 21 to be inserted into the drive rod housing 20. The other side of the drive rod 21 has slide tracks of varying depths. When the drive rod 21 slides inside the drive rod housing 20, the deep and shallow slide tracks are switched to align with the holes in the drive rod housing 20. The ball bearing 19 passes through the adapter cap 18 and the drive rod housing 20 and is embedded in the slide track of the drive rod 21. The ball bearing 19 slides along the slide track of the drive rod 21.
[0039] The sealing shell 23 is used to fix the iron core 2, and the parts of the iron core 2, the conductive coil 3, the drive rod 21 and the drive rod housing 20 exposed outside the adapter cap 18 are wrapped, allowing only the conductive coil 3 and the wires of the connecting connector 4 to pass through;
[0040] The number of coil turns, the input current of the conductive coil, the magnetic force of the magnet, the gap and fit between the drive rod housing 20 and the adapter cap 18, the fit gap between the drive rod housing 20 and the slider 19, and the fit gap between the slider 19 and the adapter cap 18 are preset. The electromagnetic field inside the device is adjusted to a reasonable value.
[0041] When the conductive coil is energized through the connector, the conductive coil generates magnetic poles that repel the magnet, separating the drive rod from the iron core; when the conductive coil is not energized through the connector, the magnet fixed on the drive rod attracts the iron core and makes the drive rod fit against the iron core.
[0042] In some embodiments,
[0043] When the conductive coil 3 is not energized through the connector 4, the magnet 22, which is pre-fixed on the drive rod 21, will attract the iron core 2 and make the drive rod 21 fit against the iron core 2. At this time, the shallow slide on the drive rod 21 will align with the ball bearing 19 and push the ball bearing 19 outward. The ball bearing 19 will protrude halfway from the hole of the adapter cap 18 and lock the adapter cap 18. The separating rod 10 is installed on the adapter cap 18 through the spring 16. The other end of the spring 16 is pressed against the fixing structure 17. The gasket 15 is sleeved on the separating rod 10 and blocks the spring 16. The nut 13, the nut 14, and the gasket 15 are used to compress the spring 16 and fix the sealing cover 9 downward along the separating rod 10. Then, the remaining sealing cover, sealing ring, and connector 4 are installed to form a sealing device.
[0044] When the conductive coil 3 is energized through the connector 4, the conductive coil 3 and the magnet on the drive rod 21 generate repulsive magnetic poles, separating the drive rod 21 from the iron core 2, so that the deep slide of the drive rod 21 is aligned with the ball bearing 19. At this time, since there is no internal force of the drive rod 21, the ball bearing 19 will slide inward under the action of the spring 16 driving the adapter cap 18 until the adapter cap 18 loses the force of the ball bearing 19. Then the adapter cap 16, the separating rod 10, and the sealing cover 9 and nut fixed by the separating rod 10 will fly out together, realizing the opening of the sealing device.
[0045] It should be noted that nut 14 must be installed properly so as not to affect the subsequent installation of the sealing cap 9.
[0046] Based on the principle of electromagnetism, a magnetic field exists around a current-carrying conductor. When current flows through a coil wound around the conductor, a magnetic field with north (N) and south (S) poles, similar to that of a magnet, is generated. The direction and magnitude of the N and S poles, as well as the strength of the magnetic field, can be controlled by changing the direction and magnitude of the current. If a conductive coil is wound around an iron core, when the coil is not energized, nearby magnets will be attracted to the iron core. When the coil is energized, the direction of the current flowing through the conductive coil can be changed, causing nearby magnets to be attracted or repelled. Based on this phenomenon, if the current-carrying coil and magnet are fixed with a suitable structure, and the electromagnetic leakage of the coil and magnet is controlled by a shielded outer shell, combined with a suitable spring and sealing structure, a sealed device controlled by external current can be designed for storing products or equipment that require airtightness and protection.
[0047] This invention designs a sealable, electromagnetically shielded, and openable space—a controllable sealing device—to meet the needs of certain products or equipment. A magnetic field is generated by an energized coil and interacts with a pre-set magnet. By controlling the on / off state of connector 4 and triggering a spring, the sealing cover 9 is ejected. After ejection, the sealing device can be restored using the same steps, achieving both sealing and opening. This invention can be applied to products requiring electromagnetic protection or isolation from the outside environment, ensuring their performance and lifespan.
[0048] In some embodiments, when the conductive coil 3 is energized through the connector 4, the magnet 22 fixed on the drive rod 21 attracts the iron core 2 and makes the drive rod 21 fit against the iron core 2 by changing the direction of the current flowing through the conductive coil 3.
[0049] In some embodiments, the sealing shell 23 has an electromagnetic shielding effect, and the amount of electromagnetic leakage from the energized coil and magnet is controlled by the sealing shell 23.
[0050] In this embodiment of the invention, a sealing shell with a shielding effect is used to protect parts at risk of leakage, thereby achieving a sealing effect.
[0051] In some embodiments, there is sufficient space between the shallow slide on the drive rod 21 and the hole in the drive rod housing 20.
[0052] In some embodiments, the conductive coil 3 is connected to the connector 4 with a wire, and the connector 4 can control whether the conductive coil 3 is energized.
[0053] In some embodiments, the separating rod 10 has a hollow interior with an internal thread, an external thread on the outside, and is of sufficient length. One side of the separating rod 10 is connected to an adapter cap, and the other side of the separating rod 10 extends through a sealing cap. The internal thread of the separating rod 10 is connected to the adapter cap 18, and the external thread of the separating rod 10 allows a nut to be screwed onto it.
[0054] In some embodiments, it further includes: sealing cover 1, sealing cover 2 7, sealing cover 3 11, sealing ring 1 5, sealing ring 2 6, sealing ring 3 8, and sealing ring 4 12.
[0055] Install sealing ring 26 and sealing cover 1 onto sealing cover 27 in sequence, and seal ring 26 is pressed to fill the gap; install sealing ring 15 and connector 4 onto sealing cover 27 in sequence, and seal ring 15 is pressed to fill the gap.
[0056] Separately insert sealing ring 38 and sealing cap 9 through separating rod 10 and fix them on sealing cover 27. Sealing ring 38 is pressed to fill the gap. Use nut 13 to press sealing cap 9 through the external thread on separating rod 10 outside sealing ring 38.
[0057] The sealing cover 311 has a non-through hole thread on its internal shaft, which is screwed onto the separating rod 10. The sealing ring 412 is passed through the separating rod 10. The sealing cover 311 is connected to the separating rod 10 and presses the sealing ring 38 to fill the gap. It also covers the part of the nut 13 and the part of the separating rod 10 that protrudes from the sealing cover 9.
[0058] In some embodiments,
[0059] The sealing cap 9 has a through hole in the middle, through which the separating rod 10 passes.
[0060] In some embodiments, sealing ring 5, sealing ring 6, sealing ring 8 and sealing ring 12 are made of rubber materials, and it is determined whether a rubber material that can block electromagnetic interference needs to be selected as required.
[0061] In some embodiments, sealing cover 1, sealing cover 7, and sealing cover 3 are made of different materials, and it is determined whether a material that can block electromagnetic interference needs to be selected as required.
[0062] In this embodiment of the invention, rubber-based materials and a shielding sealing shell are used to protect areas at risk of leakage, thereby achieving a sealing effect.
[0063] Example embodiments have been disclosed herein, and while specific terminology has been used, it is for general illustrative purposes only and should not be construed as limiting. In some embodiments, it will be apparent to those skilled in the art that features, characteristics, and / or elements described in connection with particular embodiments may be used alone, or in combination with features, characteristics, and / or elements described in connection with other embodiments, unless otherwise expressly indicated. Therefore, those skilled in the art will understand that various changes in form and detail may be made without departing from the scope of the invention as set forth by the appended claims.
