Description

Technical Field

[0001] This utility model relates to the field of magnetic self-locking coffin technology, and more specifically, to a magnetic self-locking coffin structure with high sealing performance. Background Technology

[0002] A coffin is a container used to hold and protect the remains of the deceased. Traditionally, it is mostly made of wood, which is the main material for making coffins because of its natural beauty, ease of processing, and the symbolic meaning it carries in different cultures. A complete coffin usually includes basic structures such as a lid, lining, and frame. In order to ensure the firmness and airtightness between the lid and the coffin body during use, a self-locking structure is often required.

[0003] In the use of existing technology, corresponding screw holes are set at the contact points between the edge of the cover plate and the coffin body, and bolts are tightened through the screw holes with a screwdriver or wrench, thereby firmly fixing the coffin body to the cover plate, effectively preventing accidental opening due to vibration or external force during transportation, hoisting or burial.

[0004] Existing technologies require manual alignment of bolts with screw holes during installation, which is cumbersome and affects opening and closing efficiency and ease of use. Furthermore, if the alignment is not precise enough during assembly, it can easily lead to incomplete closure, thereby reducing the overall sealing performance of the structure. Therefore, a magnetic self-locking coffin structure with high sealing performance is proposed. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a magnetically self-locking coffin structure with high sealing performance. Through the cooperation of magnetic block one, magnetic block two, magnetic block three and magnetic block four, it can achieve precise alignment between the cover and the coffin body, simplifying the installation operation. At the same time, through the cooperation of the mounting groove, mounting block, positioning groove, positioning block and return spring, a mechanical locking is formed, and a multiple stable locking system is constructed to prevent the cover from being opened accidentally.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A highly airtight magnetic self-locking coffin structure includes a coffin body, a cover plate mounted on the upper surface of the coffin body, a magnetic self-locking assembly installed between the coffin body and the cover plate, and a protective assembly installed inside the coffin body. The magnetic self-locking assembly includes multiple mounting slots opened inside the coffin body, multiple mounting blocks that match the mounting slots are fixedly connected to the lower surface of the cover plate, multiple magnetic blocks four are mounted on the outer surface of the coffin body near the mounting slots, and magnetic blocks three are mounted on the lower surface of the cover plate near the mounting blocks, with the magnetic blocks four and magnetic blocks three being magnetically connected. The protective assembly includes a protective chamber opened inside the coffin body, the interior of the protective chamber is filled with a long afterglow luminescent material, and a protective plate is mounted on the outer surface of the protective chamber.

[0010] Furthermore, the protective plate is made of acrylic glass, and a sealing gasket is fixedly connected to the bottom of the cover plate. The outer surface of the sealing gasket abuts against the outer surface of the coffin. Acrylic glass has good light transmittance and weather resistance, which can effectively protect the internal long afterglow luminescent material from external environmental erosion.

[0011] Furthermore, the bottom of the coffin is fixedly connected to multiple support legs, which can support the coffin.

[0012] Furthermore, the mounting slot has multiple movable slots inside, and a return spring is fixedly connected to the inner cavity of each movable slot. A positioning block is fixedly connected to one end of the return spring. Through the cooperation between the return spring and the positioning block, an automatic locking and releasing function can be achieved during the engagement of the mounting block and the mounting slot.

[0013] Furthermore, the mounting block has a positioning groove inside, and the positioning block engages with the inner cavity of the positioning groove. The engagement between the positioning groove and the positioning block achieves mechanical locking between the mounting block and the mounting groove, thereby improving the overall connection strength.

[0014] Furthermore, a magnetic block one is fixedly connected inside the mounting block, and a magnetic block two is installed inside the mounting groove. The magnetic block one and the magnetic block two are magnetically connected. The magnetic attraction between the magnetic block one and the magnetic block two can guide the mounting block to accurately align with the mounting groove, thereby improving the closing efficiency and ease of operation.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) This solution can achieve precise alignment between the cover and the coffin body by the cooperation of magnetic block one, magnetic block two, magnetic block three and magnetic block four, which simplifies the installation operation. At the same time, the mechanical locking is formed by the cooperation of the installation groove, installation block, positioning groove, positioning block and reset spring, and a multi-layered and stable locking system is built to prevent the cover from being opened accidentally.

[0018] (2) By tightly filling the gap between the cover and the coffin with the sealing gasket, air, moisture and dust are effectively isolated, ensuring the stability of the environment inside the coffin, extending the preservation time of the remains, and avoiding external factors from corroding the items inside the coffin.

[0019] (2) By pre-absorbing the light source through long afterglow luminescent material, it can continuously emit light in a dim environment, providing illumination for burial work at night or in low light conditions, facilitating accurate positioning and burial operations by staff, improving work efficiency and accuracy. At the same time, the continuously luminescent coffin creates a special visual effect in the tomb, taking advantage of the taboo of potential tomb raiders to deter them from a psychological level, and enhancing the protection of the coffin and its contents.

[0029] Example 1:

[0030] Please see Figures 1-4 A highly airtight magnetic self-locking coffin structure includes a coffin body 1, a cover plate 101 installed on the upper surface of the coffin body 1, and a magnetic self-locking assembly 2 installed between the coffin body 1 and the cover plate 101.

[0031] The magnetic self-locking assembly 2 includes multiple mounting slots 201 formed inside the coffin body 1. Multiple mounting blocks 202 that match the mounting slots 201 are fixedly connected to the lower surface of the cover plate 101. Multiple magnetic blocks 206 are installed on the outer surface of the coffin body 1 near the mounting slots 201. Magnetic blocks 205 are installed on the lower surface of the cover plate 101 near the mounting blocks 202. Magnetic blocks 206 and 205 are magnetically connected. Multiple moving slots are formed inside the mounting slots. A return spring 208 is fixedly connected to the inner cavity of the moving slot. A positioning block 209 is fixedly connected to one end of the return spring 208. A positioning groove 207 is formed inside the mounting block 202. The positioning block 209 engages with the inner cavity of the positioning groove 207. Magnetic block 203 is fixedly connected inside the mounting block 202. Magnetic block 204 is installed inside the mounting slot 201. Magnetic block 203 and 204 are magnetically connected.

[0032] Specifically, a protective component 3 is installed inside the coffin body 1. The protective component 3 includes a protective chamber 301 inside the coffin body 1. The protective chamber 301 is filled with a long-afterglow luminescent material 302. The long-afterglow luminescent material 302 is a special functional material that can continue to emit visible light even after the excitation stops when excited by an external light source (such as sunlight, lamplight, etc.). Because of its "afterglow" characteristic, it is also called a light-gathering material or a luminous material. When the coffin body 1 is in a dimly lit environment (such as an underground tomb or a mourning hall), the long-afterglow luminescent material 302 can continuously emit light due to the light source absorbed in advance. A protective plate 303 is installed on the outer surface of the protective chamber 301. The protective plate 303 is made of acrylic glass. A sealing gasket 304 is fixedly connected to the bottom of the cover plate 101. The outer surface of the sealing gasket 304 abuts against the outer surface of the coffin body 1. Multiple support legs 102 are fixedly connected to the bottom of the coffin body 1.

[0033] Furthermore, the cover plate 101 is aligned with the coffin body 1. The attraction forces generated by magnetic blocks 204 and 206 on magnetic blocks 203 and 205 respectively cause the mounting block 202 on the lower surface of the cover plate 101 to automatically align with the mounting groove 201 inside the coffin body 1. Moving the cover plate downwards causes the mounting block 202 to engage with the mounting groove 201. Simultaneously, magnetic blocks 203 and 204 engage, and magnetic blocks 206 and 205 engage, thus forming a multiple locking structure and completing the connection between the cover plate 101 and the coffin body 1. The coffin body 1 features a magnetic self-locking mechanism. Through the interaction of the long-afterglow luminescent material 302 and the protective plate 303, the coffin body 1 emits light, which is evenly transmitted through the acrylic glass protective plate 303. During the burial process, the coffin body 1 provides illumination for the staff, facilitating accurate positioning and burial operations. At the same time, when encountering thieves, the coffin body 1 will still emit light in the dark underground environment, creating a significant visual impact and having a psychological deterrent effect on thieves to a certain extent, thus playing an auxiliary role in preventing theft.

[0034] Working principle: In use, the coffin 1 is first placed in the outside environment, allowing the long-afterglow luminescent material 302 inside the protective chamber 301 to absorb the light source. Then, when it is necessary to close the cover 101 to the coffin 1, multiple people work together to lift the cover 101 and align it with the coffin 1. At this time, the attraction force generated by magnetic blocks 204 and 206 on magnetic blocks 203 and 205 respectively causes the mounting block 202 on the lower surface of the cover 101 to automatically align with the mounting groove 201 inside the coffin 1, moving it downwards to engage with the mounting groove 201. During the engagement process, the mounting block 202 will first touch... Positioning block 209 is pushed, causing positioning block 209 to move into positioning groove 207 via return spring 208. When mounting block 202 is fully engaged with mounting groove 201, positioning block 209 engages with positioning groove 207 via the elasticity of return spring 208. At the same time, magnetic block 1 203 and magnetic block 204 engage, and magnetic block 4 206 and magnetic block 3 205 engage, thus forming a multi-locking structure to complete the magnetic self-locking of cover plate 101 and coffin body 1, ensuring a firm connection between cover plate 101 and coffin body 1. At the same time, the sealing gasket 304 filled between cover plate 101 and coffin body 1 can improve its sealing performance.

[0035] Subsequently, through the interaction of the long-afterglow luminescent material 302 and the protective plate 303, the coffin 1 emits light. The light is evenly transmitted through the acrylic glass protective plate 303, providing illumination for the staff during the burial process, facilitating accurate positioning and burial operations. At the same time, when encountering thieves, the coffin 1 will still emit light in the dark underground environment, creating a significant visual impact. In addition, its continuous luminescence characteristic, unlike conventional light sources, can have a psychological deterrent effect on thieves to a certain extent, thus playing an auxiliary role in preventing theft.

[0036] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
