Description

Technical Field

[0001] This utility model relates to the technical field of coin collectibles, and in particular to a protective box for ancient coins. Background Technology

[0002] Ancient coins, as collectibles with historical and cultural value, have their collectible value directly determined by their condition. To prevent ancient coins from being oxidized, corroded, or physically damaged during storage and circulation, collectors usually use special protective boxes for sealing and storage.

[0003] Most existing ancient coin protective boxes are made of hard plastic, and their interiors typically have grooves or slots that roughly match the shape of the coins. While this design can provide some containment and isolation for ancient coins, its relatively simple structure often has limitations. Because the size and thickness of ancient coins are not entirely standardized, protective boxes of the same specifications cannot achieve a tight fit with coins of different sizes.

[0004] When a gap exists between the coin and the inner groove of the protective box, the coin will shift and collide within the box during transport, movement, or display. This continuous, minute friction and impact will gradually wear down the surface of the ancient coin, especially damaging its precious original patina and fine graphic details. Over time, this will lead to an irreversible decrease in its collectible value. Current technology lacks a structure that can stably and securely hold the coin to effectively prevent internal shaking and wear.

[0005] Therefore, this utility model proposes an ancient coin protective box to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an ancient coin protective box, which aims to improve the problems of the simple internal fixing structure that leads to coin shaking and wear, and the easy loss of the top cover that causes inconvenience in use.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an ancient coin protective box, comprising a lower box and an upper box detachably fastened to the lower box; and a protective component and an anti-loss component, wherein the protective component is fixedly connected to the inside of the lower box for limiting and fixing the ancient coins placed therein, and the anti-loss component is connected between the lower box and the upper box, thereby connecting the upper and lower boxes in series to prevent the upper box from accidentally falling off during use;

[0008] Preferably, the protective component includes a limiting ring, which is fixedly connected to the inner bottom surface of the lower box, and the limiting ring encloses and forms a placement groove;

[0009] Preferably, the protective component further includes a fixing block, which is fixedly connected to the inner wall of the limiting ring;

[0010] Preferably, the protective component further includes a rubber block, which is fixedly connected to the interior of the fixing block;

[0011] Preferably, the surface of the rubber block facing the placement groove is provided with the micro-protrusions;

[0012] Preferably, the anti-loss component includes a first connecting block and a second connecting block, wherein the first connecting block is fixedly connected to the outer wall of the lower box, and the second connecting block is fixedly connected to the outer wall of the upper box;

[0013] Preferably, the anti-loss component further includes a connecting rope, the two ends of which are respectively connected to the first connecting block and the second connecting block;

[0014] Preferably, the inner surface of the upper box is provided with a label groove.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model solves the problem that the simple internal fixing structure of ancient coin protective boxes in the prior art leads to easy wear and tear of coins when they shake inside the box by setting a protective component inside the lower box and setting a rubber block with micro-protrusions on the inner wall of the limiting ring of the protective component. It achieves the goal of firmly fixing ancient coins by using elasticity and friction, effectively improving the stability of protection.

[0017] 2. This utility model solves the problem in the prior art where the top cover of the protective box is completely separated from the box body and is easily lost or damaged when opened by setting an anti-loss component connected by a connecting rope between the outer walls of the lower box and the upper box. This ensures that the upper box is always connected to the lower box when it is open, thereby improving the reliability and durability of the entire protective box.

[0018] 3. This utility model solves the problem that some protective boxes in the prior art lack a dedicated marking area, making it inconvenient for collectors to classify and manage coins, by opening a label groove on the inner surface of the upper box. It provides users with a convenient way to mark information and improves the efficiency of collection management. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-5 The present invention provides an embodiment of an ancient coin protective box, which includes a lower box 1 and an upper box 2. The upper box 2 is detachably fastened to the lower box 1. It also includes a protective component 4 and an anti-loss component 5. The protective component 4 is fixedly connected to the inside of the lower box 1, and the anti-loss component 5 is connected between the lower box 1 and the upper box 2.

[0028] Specifically, the protective component 4 includes a limiting ring 401, a fixing block 403, a rubber block 404, and micro protrusions 405. The limiting ring 401 is fixedly connected to the inner bottom surface of the lower box 1. The inner peripheral wall of the limiting ring 401 forms a placement groove 402 for accommodating ancient coins. The fixing block 403 is fixedly connected to the inner wall of the limiting ring 401. The rubber block 404 is fixedly connected to the inside of the fixing block 403. Micro protrusions 405 are provided on the surface of the rubber block 404 facing the placement groove 402. When the ancient coin is placed in the placement groove 402, the micro protrusions 405 contact the edge of the ancient coin, and the ancient coin is fixed by friction.

[0029] The anti-loss component 5 includes a first connecting block 501, a second connecting block 502, and a connecting rope 503. The first connecting block 501 is fixedly connected to the outer wall of the lower box 1, the second connecting block 502 is fixedly connected to the outer wall of the upper box 2, and the two ends of the connecting rope 503 are respectively connected to the first connecting block 501 and the second connecting block 502. Through the connecting action of the connecting rope 503, the upper box 2 is prevented from accidentally falling out when it is open.

[0030] The inner surface of the upper box 2 is provided with a label groove 3, which is used to attach labels to identify the ancient coins inside the box;

[0031] The limiting ring 401 inside the protective component 4 serves as a fixed base and is fixedly connected to the inner bottom surface of the lower box 1. A fixing block 403 is fixedly connected to the inner wall of the limiting ring 401. This arrangement provides a stable mounting point for subsequent components. A rubber block 404 is fixedly connected inside the fixing block 403, and micro protrusions 405 are provided on the surface of the rubber block 404 facing the placement groove 402. When the ancient coin is placed in the placement groove 402 formed by the limiting ring 401, the edge of the ancient coin will be in close contact with the surface of multiple micro protrusions 405. This friction fixing structure, which is composed of the elasticity of the rubber block 404 and the micro protrusions 405, can generate sufficient clamping force and friction to stably fix the ancient coin in the center position of the placement groove 402, thereby ensuring that the ancient coin will not be displaced or worn due to vibration or shaking inside the box.

[0032] The anti-loss component 5 solves the problem that the upper box 2 is easy to lose. Specifically, the first connecting block 501 is fixedly connected to the outer wall of the lower box 1, the second connecting block 502 is fixedly connected to the outer wall of the upper box 2, and the two ends of the connecting rope 503 are respectively connected to the first connecting block 501 and the second connecting block 502, so as to keep the upper box 2 and the lower box 1 always connected and avoid the upper box 2 from accidentally falling off or being lost.

[0033] The internal structure of the protective component 4 is further defined. Specifically, the fixing block 403 is fixedly connected to the inner wall of the limiting ring 401, while the rubber block 404 is fixedly connected to the inside of the fixing block 403. This hierarchical connection structure ensures the stability and reliability of the position of the rubber block 404. To maximize the fixing friction, please refer to... Figure 4The surface of the rubber block 404 facing the placement groove 402 is provided with micro protrusions 405. The micro protrusions 405 are preferably honeycomb-shaped or arrayed protrusions. This design increases the contact pressure and friction coefficient between the rubber block 404 and the edge of the ancient coin, thereby achieving a firm anti-shaking effect. The specific structure of the anti-loss component 5 is as follows: the first connecting block 501 is fixedly connected to the outer wall of the lower box 1, the second connecting block 502 is fixedly connected to the outer wall of the upper box 2, and the first connecting block 501 and the second connecting block 502 are connected by the connecting rope 503. The connecting rope 503 is preferably a flexible and tensile-resistant rope, thereby effectively preventing the upper box 2 from falling off accidentally without affecting the normal opening and closing operation. In order to facilitate the user to classify and manage the ancient coins in the box, a label groove 3 is integrally formed on the inner surface of the upper box 2. The label groove 3 is a rectangular recessed area, which is convenient for pasting or embedding information labels.

[0034] Working principle: When it is necessary to store ancient coins, firstly, pry open the upper box 2 from the detachable fastening part on the lower box 1, and place the ancient coin into the placement groove 402 formed by the limiting ring 401 inside the lower box 1. At this time, the edge of the ancient coin comes into contact with the micro protrusions 405 on the surface of the rubber block 404. Due to the elasticity of the rubber block 404 itself and the micro protrusions 405 increasing the contact friction, the ancient coin is firmly clamped and fixed in the center of the placement groove 402, thereby effectively avoiding wear caused by shaking or vibration. After storage, simply fasten the upper box 2 back onto the lower box 1.

[0035] When the ancient coin protective box is opened, during the separation of the upper box 2 and the lower box 1, the first connecting block 501 fixedly connected to the outer wall of the lower box 1 and the second connecting block 502 fixedly connected to the outer wall of the upper box 2, as well as the connecting rope 503 connected between the two connecting blocks, work together to pull and limit the upper box 2, thereby preventing the upper box 2 from being accidentally slipped and damaged or lost when opened.

[0036] In addition, users can place information tags in the label slots 3 on the inner surface of the upper box 2 to facilitate the classification, identification and management of their collection of ancient coins.
