Description
Technical Field
[0001] This utility model relates to the technical field of burial products, specifically a sealed urn. Background Technology
[0002] Among existing funeral supplies, urns are a common container used to store the ashes of the deceased. To protect the ashes from external environmental influences, urns typically need to possess excellent sealing performance and protective functions. Existing urns have made some progress in sealing and protection, for example, by using a sealing ring between the urn body and the lid. However, existing technology still has some shortcomings, mainly in the following aspects:
[0003] 1. Insufficient sealing performance:
[0004] Although existing urns achieve basic sealing functions through sealing rings, their sealing performance may decline during long-term use due to aging, deformation, or external forces, allowing the interior of the urn to be affected by external air, moisture, or contaminants.
[0005] 2. Inadequate protective functions:
[0006] Existing urns have certain limitations in terms of protection. For example, their functions such as dustproofing, waterproofing, corrosion prevention, and rust prevention are not perfect, and they are easily affected by the external environment, which can lead to the contamination or damage of the ashes inside the urn.
[0007] 3. Insufficient anti-theft features:
[0008] Existing urns also have shortcomings in terms of theft prevention, typically relying on simple friction between the lid and the urn or a simple latch structure to prevent accidental opening. However, this structure is easily malfunctioned by external forces and cannot effectively prevent unauthorized opening of the urn.
[0009] To address the above problems, some existing technological solutions also have certain limitations. For example:
[0010] Increasing the number or thickness of sealing rings can improve sealing performance to some extent, but it will increase production costs and manufacturing difficulty, and the aging problem of sealing rings still cannot be fundamentally solved.
[0011] Using complex mechanical locks: Some urns use complex mechanical lock structures to achieve theft prevention, but such structures are usually complicated to operate, inconvenient to use, and prone to mechanical failure.
[0012] Reliance on external locks: Some urns require external locks to prevent opening, but this not only increases the cost of use, but may also affect the overall aesthetics and portability of the urn.
[0013] Therefore, a sealed urn is proposed to address the current shortcomings. Utility Model Content
[0014] The technical problem to be solved by this utility model is to overcome the defects of the above-mentioned technology and provide a sealed urn.
[0015] To solve the above-mentioned technical problems, the technical solution provided by this utility model is a sealed urn: including a urn body, an upper cover body, and a backstop mechanism;
[0016] The container has an internal space for holding cremated remains. The upper end of the container is coaxially provided with an annular connecting plate. The upper cover is coaxially provided with an upper cover seat that cooperates with the annular connecting plate. The annular connecting plate is provided with multiple limiting spiral grooves in its circumference. The upper cover seat is provided with limiting pins that cooperate with the limiting spiral grooves.
[0017] The anti-reverse mechanism includes an anti-reverse seat and an anti-reverse body. The anti-reverse seat is disposed inside the annular connecting plate. An anti-reverse pin is slidably disposed inside the anti-reverse seat. A spring is disposed inside the anti-reverse seat that abuts against the anti-reverse pin and the anti-reverse seat. The anti-reverse body is disposed inside the upper cover seat and cooperates with the anti-reverse pin.
[0018] As an improvement, the tank body is a hollow cylindrical structure, and the upper cover can rotate around the tank body axis.
[0019] As an improvement, the bottom of the anti-reverse body is provided with multiple locking grooves that cooperate with the anti-reverse pin, and the locking grooves are inclined on the side of the upper cover that rotates.
[0020] As an improvement, in the locked state, the limiting pin engages with the limiting spiral groove and rotates to the end of the limiting spiral groove, and the anti-reverse pin engages with the locking groove.
[0021] As an improvement, the limiting spiral groove is a horizontal L-shaped structure with its short side extending to the upper side of the annular connecting disc.
[0022] As an improvement, the annular connecting plate is provided with a sealing groove, and a sealing ring that mates with the upper cover seat is provided in the sealing groove.
[0023] The advantages of this utility model compared with the prior art are as follows:
[0024] 1. An annular connecting plate and a top cover seat are installed between the container body and the top cover body. A sealing groove is provided on the annular connecting plate, and a sealing ring is placed in the groove. Through the compression and deformation of the sealing ring, a reliable seal is achieved between the container body and the top cover body, which can effectively isolate the intrusion of external substances such as dust and moisture, maintain the purity of the cremated remains, and ensure the long-term stability of the sealing performance.
[0025] 2. The rotation control and self-locking function of the upper cover are achieved through the cooperation of the limiting pin and the limiting spiral groove. The horizontal L-shaped structure of the limiting spiral groove ensures that the upper cover can only rotate within a predetermined range, avoiding failure of the self-locking mechanism due to excessive rotation. At the same time, the snap-fit design of the anti-reverse pin and the locking groove ensures that the upper cover is firmly locked in the closed state and cannot be opened again, which not only improves the safety of using the urn but also enhances the user's sense of security.
[0026] 3. The anti-locking mechanism, through the action of the spring, ensures that the anti-locking pin is always in the locked position when not subjected to external force, thus ensuring the reliability and durability of the self-locking function and effectively preventing accidental opening.
[0027] 4. The engagement process between the top cover and the tank is simple and intuitive. Users only need to rotate the top cover, and the limit pin and anti-reverse pin will automatically complete the positioning and locking, reducing user operation steps and improving ease of use. At the same time, the path design of the limit spiral groove ensures the rotation angle and direction of the top cover, avoiding locking failure caused by user misoperation.

[0044] In the description of the embodiments of the utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the utility model according to the specific circumstances.
[0045] As shown in the attached drawings, a sealed urn includes a body 1, an upper cover 2, and a backstop mechanism 3.
[0046] The container 1 has an internal space for holding cremated remains. In this embodiment, the container 1 is a hollow cylindrical structure.
[0047] The upper end of the tank body 1 is coaxially provided with an annular connecting plate 4, and the upper cover body 2 is coaxially provided with an upper cover seat 5 that cooperates with the annular connecting plate 4. The upper cover seat 5 is an annular structure that cooperates with the annular connecting plate 4 to ensure that the upper cover body 2 can be stably installed on the tank body 1.
[0048] The annular connecting plate 4 is provided with a sealing groove 8, and a sealing ring 9 that cooperates with the upper cover seat 5 is provided in the sealing groove 8 to ensure the sealing between the upper cover body 2 and the tank body 1.
[0049] During implementation, when the upper cover 2 is fitted with the tank 1, the upper cover seat 5 contacts the annular connecting disc 4, and the sealing ring 9 is compressed in the sealing groove 8 to form a reliable sealing barrier to prevent air, moisture or other pollutants from entering the interior of the tank 1.
[0050] In practice, the upper cover 2 can rotate around the axis of the tank 1, thereby closing the upper cover 2 and the tank 1.
[0051] The annular connecting disk 4 is provided with multiple limiting spiral grooves 6 around its circumference. Specifically, the limiting spiral groove 6 is a horizontal L-shaped structure and its short side extends to the upper side of the annular connecting disk 4.
[0052] The upper cover 5 is provided with a limiting pin 7 that cooperates with the limiting spiral groove 6;
[0053] During implementation, the rotation range and direction of the upper cover 2 can be controlled by the movement of the limiting pin 7 within the limiting spiral groove 6. Simultaneously, this ensures the self-locking effect of the self-locking mechanism 3, preventing excessive rotation of the upper cover 2 that could lead to its failure.
[0054] The anti-locking mechanism 3 achieves self-locking between the tank body 1 and the upper cover 2, ensuring that the upper cover 2 cannot be opened again when closed. The anti-locking mechanism 3 includes an anti-locking seat 31 and an anti-locking body 32. The anti-locking seat 31 is located inside the annular connecting plate 4. An anti-locking pin 33 is slidably provided in the anti-locking seat 31. The anti-locking pin 33 can move along the axial direction of the tank body 1, that is, the anti-locking pin 33 can slide freely in the anti-locking seat 31. A spring 34 is provided in the anti-locking seat 31 to abut against the anti-locking pin 33 and the anti-locking seat 31. Under the action of the spring 34, the anti-locking pin 33 is always in the locked position when not subjected to external force.
[0055] The anti-reverse body 32 is disposed inside the upper cover seat 5 and cooperates with the anti-reverse pin 33. The anti-reverse body 32 is fixedly connected to the upper cover body 2 and can move with the rotation of the upper cover body 2. It cooperates with the anti-reverse pin 33 to realize the self-locking function.
[0056] Specifically, the bottom of the anti-reverse body 32 is provided with a plurality of locking grooves 35 that cooperate with the anti-reverse pin 33, and the locking grooves 35 are inclined on the side of the upper cover 2 that rotates.
[0057] By using a sloped side of the locking groove 35 corresponding to the rotation direction, the anti-locking pin 33 can smoothly enter the locking groove 35 during the closing process of the upper cover 2, thus achieving self-locking.
[0058] Specifically:
[0059] During the closing process, the user rotates the upper cover 2, and the anti-reverse pin 33 contacts the inclined surface of the locking groove 35. As the upper cover 2 continues to rotate, the anti-reverse pin 33 moves along the inclined surface and eventually engages with the locking groove 35. At the same time, the spring 34 provides continuous elastic force to ensure reliable engagement between the anti-reverse pin 33 and the locking groove 35, achieving self-locking.
[0060] In the locked state, the limiting pin 7 engages with the limiting spiral groove 6 and rotates to the end of the limiting spiral groove 6, that is, the upper cover 2 has rotated to the predetermined closed position, and the limiting pin 7 reaches the end of the limiting spiral groove 6. At this time, the anti-reverse pin 33 engages with the locking groove 35.
[0061] Specifically, by setting the limiting spiral groove 6, not only is the rotation angle of the upper cover 2 controlled, but the precise positioning of the upper cover 2 in the closed position is also ensured.
[0062] In practice, the cooperation between the positioning pin 7 and the limiting spiral groove 6, as well as the engagement between the anti-reverse pin 33 and the locking groove 35, together realize the self-locking function of the urn. At this time, the upper cover 2 is firmly locked in the closed state and cannot be opened.
[0063] In a specific implementation of this utility model, the upper cover 2 and the tank 1 begin to cooperate. At this time, the limiting pin 7 is located on the short side of the limiting spiral groove 6. As the upper cover 2 gradually connects with the tank 1, the limiting pin 7 begins to enter the groove through the short side of the limiting spiral groove 6. As the upper cover 2 moves further, the limiting pin 7 moves along the path of the limiting spiral groove 6 from the short side to the long side.
[0064] When the upper cover 2 starts to rotate, the limiting pin 7 moves along the long side of the limiting spiral groove 6, and the anti-reverse pin 33 gradually approaches the locking groove 35 at the bottom of the anti-reverse body 32. When the limiting pin 7 rotates to the end of the limiting spiral groove 6, the anti-reverse pin 33 engages with the locking groove 35, thereby achieving self-locking between the tank body 1 and the upper cover 2.
[0065] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
