Abstract
Description
Technical Field
[0001] This invention belongs to the field of cultural relic earthquake protection technology, and relates to a magnetic adsorption type cultural relic earthquake protection device and a cultural relic display system. Background Technology
[0002] Earthquake protection of museum collections is an important issue. Traditional fixing methods often use metal clamps, brackets, adhesives, and other direct contact fixing methods. These methods may have the following drawbacks: 1) They may cause stress concentration or physical damage to the artifact itself; 2) The fixing method is irreversible, and removal may be difficult or leave traces; 3) They lack an effective horizontal energy dissipation mechanism, which may cause the artifact and the bracket to overturn during an earthquake.
[0003] Magnetic fixation, as a non-contact fixing method, has been applied in recent years. However, existing magnetic fixation devices are usually not adjustable, making them unsuitable for artifacts of different weights and bottoms; their complex structures make it difficult to precisely control the distance between the magnet and the artifact, thus hindering the optimization of the adsorption force; and they are inconvenient to install and adjust.
[0004] Therefore, there is an urgent need in the field for a magnetic fixing device that is precisely adjustable, easy to install, safe and reliable, and specifically designed for earthquake resistance. Summary of the Invention
[0005] The purpose of this invention is to overcome any one or more defects in the existing technology, such as limited magnetic force adjustment, poor adaptability, and difficulty in optimizing the adsorption force, so as to provide a magnetic adsorption type cultural relic shockproof device and cultural relic display system.
[0006] This invention aims to improve the shock resistance of cultural relics during exhibition and storage. It achieves precise control of the magnet height through a unique cup-shaped structure and a built-in lifting and adjusting mechanism, thereby providing adjustable, reliable and non-invasive shockproof fixation for cultural relics.
[0007] The objective of this invention can be achieved through the following technical solutions: One of the technical solutions of the present invention is to provide a magnetic adsorption type cultural relic shockproof device, including a cup body, a lifting and adjusting mechanism, a magnet fixing mechanism, and a magnet; The cup body has a cavity for accommodating the lifting adjustment mechanism, the magnet fixing mechanism, and the magnet; The lifting and adjusting mechanism includes a cup lid and a screw body connected to the cup lid to form a threaded pair. One end of the screw body is connected to a magnet fixing mechanism. The magnet fixing mechanism has a groove at the top for accommodating the magnet.
[0008] In some embodiments, the cavity of the cup body includes a threaded hole for the screw body to pass through.
[0009] In some specific embodiments, the inner wall of the cavity of the cup body and the magnet fixing mechanism are in clearance fit.
[0010] In some specific embodiments, the cup body is made of a non-ferromagnetic material.
[0011] In some specific embodiments, the non-ferromagnetic material is selected from any one of aluminum, copper, stainless steel, or engineering plastics.
[0012] In some specific embodiments, the outer casing of the cup is provided with a silicone protective sleeve.
[0013] In some specific embodiments, the magnet is a permanent magnet or an electromagnet.
[0014] In some specific embodiments, when the magnet is an electromagnet, the device further includes a push-button switch and / or a remote control switch disposed on the cup body for controlling the electromagnet.
[0015] In some specific embodiments, the permanent magnet is a neodymium iron boron magnet.
[0016] In some specific embodiments, the cup lid is provided with a threaded hole that connects to the screw body.
[0017] The second technical solution of the present invention is to provide a cultural relic display system, including a display stand, a magnetic adsorption type cultural relic shockproof device as described in one of the above technical solutions located at the bottom of the display stand, and a cultural relic located on the display stand at the position corresponding to the magnetic adsorption type cultural relic shockproof device. The cultural relic is made of ferromagnetic material or non-ferromagnetic material. If the cultural relic is made of non-ferromagnetic material, a magnetically conductive material is also placed inside the cultural relic.
[0018] Compared with the prior art, the present invention has the following advantages: (1) Precisely adjustable: The height of the magnet can be steplessly adjusted by rotating the cup lid, thereby precisely controlling the adsorption force on the cultural relics and adapting to cultural relics of different weights and needs.
[0019] (2) High stability: The main body of the cup and the magnet fixing mechanism provide a robust enclosure and guide for the magnet, ensuring that it will not sway during vibration and that the direction of magnetic force is stable.
[0020] (3) Excellent seismic performance: Magnetic adsorption provides a constraint force in the vertical direction, while the horizontal direction allows for slight slippage or rotation between the artifact and the device, thereby effectively dissipating the energy input by the earthquake and preventing the artifact from being subjected to excessive inertial force due to rigid fixation.
[0021] (4) Non-invasive and reversible: No need to drill holes or use adhesives on the cultural relics. It is only necessary to put magnetic conductive materials (such as nickel-plated steel balls) inside the cultural relics to achieve fixation without damaging the cultural relics.
[0022] (5) Compact structure and easy installation: The device has a compact overall structure and can be directly attached to the display stand or bracket. The debugging process is simple and efficient.
[0023] (6) Enhanced protection: The external silicone protective cover effectively prevents hard contact between the artifact and the device, providing additional cushioning.
[0024] This invention, a magnetic adsorption-type shockproof device for cultural relics, is particularly suitable for the display and protection of cultural relics in museums, art galleries, and other cultural institutions. It effectively mitigates the damage caused to cultural relics by external forces such as earthquakes through magnetic adsorption and has the advantages of convenient installation, flexible adjustment, safety and reliability, and high protective performance.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. These embodiments are based on the technical solution of the present invention and provide detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0032] Example 1: like Figure 1As shown, a magnetic adsorption type shockproof device for cultural relics includes a cup body 1, a lifting and adjusting mechanism, a magnet fixing mechanism 2, and a magnet 5. The cup body 1 has a cavity for accommodating the lifting and adjusting mechanism, the magnet fixing mechanism 2, and the magnet 5. The lifting and adjusting mechanism can be a lifting and adjusting bolt, including a cup lid 4 and a screw body 3 connected to the cup lid 4 to form a threaded pair. One end of the screw body 3 is connected to the magnet fixing mechanism 2. The top of the magnet fixing mechanism 2 has a groove for accommodating the magnet 5.
[0033] In this technical solution, when the cup lid 4 is rotated, the screw body 3 and the magnet fixing mechanism 2 can be driven to move up and down along the main axis of the cup body 1 through the transmission of the threaded pair formed by the cup lid 4 and the screw body 3, thereby changing the distance between the magnet 5 and the top of the cup body 1 and realizing precise adjustment of the magnetic adsorption force.
[0034] In a preferred embodiment, the cavity of the cup body 1 includes a threaded hole for the screw body 3 to pass through. The inner wall of the cavity of the cup body 1 is clearance-fitted with the magnet fixing mechanism 2 to ensure that it can only move along the axial direction of the cup body 1.
[0035] As a preferred embodiment, the cup body 4 is made of a non-ferromagnetic material. More preferably, the cup body 4 is made of aluminum, copper, stainless steel or engineering plastic.
[0036] As a preferred embodiment, the cup body 4 is covered with a silicone protective sleeve 6 to cushion and prevent damage caused by direct contact between the artifact and the device.
[0037] In a preferred embodiment, the magnet 5 is a permanent magnet or an electromagnet. When the magnet 5 is an electromagnet, the device also includes a push-button switch 8 and / or a remote control switch 7 disposed on the cup body 1 for controlling the electromagnet.
[0038] When magnet 5 is a permanent magnet, it can be a neodymium iron boron magnet or other strong magnetic materials.
[0039] Example 2 This embodiment also provides a magnetic adsorption type cultural relic shockproof device, which mainly consists of a cup body 1, a cup lid 4, a magnetic fixing mechanism 2, a screw body 3, a magnet 5, a silicone protective sleeve 6, a remote control switch 7, and a button switch 8.
[0040] The cup body 1 is preferably made of high-strength aluminum alloy through machining. It has a cylindrical structure with a precision-machined internal cavity. Its top is an adsorption surface for contacting or approaching the artifact.
[0041] The cup lid 4 is also made of aluminum alloy, and it is connected to the bottom of the cup body 1 by the internal thread of the screw body 3. A threaded hole is machined in the center of the cup lid 4, forming a threaded pair with the screw body 3.
[0042] The magnet fixing mechanism 2 is a cylindrical slider whose outer diameter is fitted with the inner cavity of the cup body 1, allowing it to slide smoothly up and down along the inner cavity. A magnet receiving cavity is located at the center of the magnet fixing mechanism 2 to tightly press in a high-strength neodymium iron boron permanent magnet or electromagnet. If an electromagnet is used, an external remote control switch 7 and a push-button switch 8 are required to control the electromagnet.
[0043] The upper end of the screw body 3 is connected to the bottom center of the magnet fixing mechanism 2, and its lower end passes through the threaded hole of the cup body 1 and is connected to the cup lid 4 to form a threaded pair.
[0044] The silicone protective sleeve 6 is set on the outside of the cup body 1. It has a certain degree of elasticity and wear resistance, which can effectively prevent the cultural relics from directly contacting the cup body and reduce the risk of bumps and knocks.
[0045] Example 3: This embodiment provides a method for using the magnetic adsorption type cultural relic shockproof device in Embodiments 1 and 2, including the following steps: The top outer surface of the cup body 1 is directly attracted and fixed to the bottom of the display stand 11 or display case by the magnetic force generated by the permanent magnet inside. The bottom of the display stand 11 needs to be made of magnetic material (such as steel or iron) or have a magnetic material plate (sheet) attached.
[0046] During adjustment, rotate the lid 4 clockwise. Since the lid 4 is connected to the cup body 1 via the screw body 3, it cannot move axially on its own. The rotation forces the screw body 3, which meshes with it, to move upwards, thereby pushing the entire magnet fixing mechanism 2 and the permanent magnet closer to the top of the cup body 1, increasing the magnetic force. Figure 3 As shown. This measure increases the device's adsorption force on the artifact 9 above, and simultaneously enhances the device's adsorption and fixation force on the bottom of the steel display stand 11, making the device itself more stable.
[0047] Conversely, rotating the lid 4 counterclockwise will cause the screw body 3 to move downwards, moving the magnetic fixing mechanism 2 and the permanent magnet away from the top of the cup body 1, while simultaneously weakening the bidirectional attraction between the artifact 9 and the display stand 11. Figure 2 As shown.
[0048] If magnet 5 is an electromagnet, the current switch can be adjusted by an external remote control switch 7 to achieve remote or automated management. If the remote control switch 7 fails, a push-button switch 8 can be used for control.
[0049] like Figure 4 As shown, this is a cultural relic display system. The final usage state of the magnetic adsorption type cultural relic shockproof device of this invention is as follows: The device of this invention is fixed to the bottom of the display stand 11 by adsorption on the outer surface of the top of the cup body 1. If the artifact 9 is a ferromagnetic material that can be attracted by a magnet, the artifact 9 can be placed directly on the pad 12 in the corresponding position. If the artifact 9 is a non-metallic material that cannot be attracted by a magnet, such as ceramic or glass, an iron block 10 or multiple nickel-plated steel balls need to be placed inside the artifact 9 as a magnetic conductive material. The strength of the adsorption force can be adjusted by placing magnetic conductive materials of different sizes. After the artifact 9 is placed in place, the height of the screw body 3 and the magnet 5 is adjusted by rotating the cup lid 4, thereby adjusting the magnetic force of the magnet 5 on the artifact 9 until the artifact 9 is firmly attracted.
[0050] This installation method requires no drilling into booth 11, is completely non-invasive, and greatly protects the integrity and aesthetics of booth 11 itself. At the same time, the installation position can be flexibly moved, facilitating quick setup and adjustments. The entire system forms a stable, earthquake-resistant structure through magnetic coupling.
[0051] Refer to the section on magnetic circuits and magnets regarding the force per unit volume experienced by a magnetic medium in a magnetic field: Then the force on the magnetic medium can be obtained by integration: Where F is the attraction force, measured in Newtons (N), B is the magnetic flux density of the magnet surface, measured in Tesla (T), and S is the effective contact area between the magnetic pole and the iron block, measured in square meters (m²). 2 μ0 is the free permeability, with a value of 4π × 10⁻⁶. -7 N / A 2 (or H / m). If the force exerted by the iron block 10 inside the artifact 9 is required, the magnetic induction intensity B on the surface of the iron block 10 needs to be measured using a Tesla meter, and then substituted into the formula to calculate it, which can provide a theoretical reference value for this invention.
[0052] The above description of the embodiments is provided to enable those skilled in the art to understand and use the invention. It will be apparent to those skilled in the art that various modifications can be made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present invention is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the invention should be within the protection scope of the present invention.
