[0002] In the jewelry industry, across scenarios such as display, sales, collection, and cultural dissemination, jewelry, as a special item possessing aesthetic, economic, and emotional value, always prioritizes display effectiveness and safety. Jewelry display cases, as specialized containers for holding and displaying jewelry, are widely used in various settings including jewelry store window displays, exhibition exhibits, private collection storage, and high-end jewelry appreciation events. Jewelry materials are often precious and fragile, such as diamonds, gemstones, and pearls. During display and handling, they are easily affected by external factors such as collisions, friction, dust contamination, and humidity changes, leading to surface scratches, loss of luster, and even structural damage. At the same time, a high-quality display method can highlight the design beauty, craftsmanship details, and material luster of jewelry, enhancing its aesthetic value and market appeal. Therefore, jewelry display containers must meet the basic requirement of safety protection while also ensuring a good display effect. Jewelry display cases with protective functions are specifically designed based on this core need. Their core positioning is to provide jewelry with a stable carrying and exquisite display space while incorporating protective functions.

[0003] Patent CN103565057A discloses a jewelry display box.

A first positioning block 523 and a second positioning block 524 are fixedly installed at a 90-degree angle on the outer surface of positioning shaft 522. The first positioning block 523 and the second positioning block 524 are the same in shape and size. The distance between the opposite sides of the first positioning block 523 and the second positioning block 524 is equal to the thickness of fixing rod 520. A release groove 521 is provided on the side of fixing rod 520. The cross-sectional shape and size of release groove 521 are the same as those of the second positioning block 524.

[0029] As attached Figure 5 To the attached Figure 11As shown, an installation shaft 502 is fixedly installed on the inner wall of the placement groove 501. A protective plate 510 is rotatably installed on the outer surface of the installation shaft 502. The length and width of the protective plate 510 are equal to the length and width of the placement groove 501, respectively. A second installation groove 508 and a third installation groove 509 are provided on the inner wall of the placement groove 501. The support assembly includes a front protective plate 516 rotatably installed on the lower side of the protective plate 510 and a fixing block 513 fixedly installed on the lower side of the protective plate 510. A first positioning plate 515 and a rotating shaft 514 are fixedly installed on the side of the fixing block 513. When the front protective plate 516 is in contact with the first positioning plate 515 and the protective plate 510 is parallel to the bottom of the inner wall of the placement box 102, the front protective plate 516 moves downward. The end face coincides with the bottom of the inner wall of the placement box 102. A side guard plate 512 is rotatably mounted on the outer surface of the rotating shaft 514. A second positioning plate 517 is fixedly mounted on the side of the guard plate 510. When the side guard plate 512 and the second positioning plate 517 are in contact and the guard plate 510 is parallel to the bottom of the inner wall of the placement box 102, the lower end face of the side guard plate 512 coincides with the bottom of the inner wall of the placement box 102.

[0030] As attached Figure 10 To the attached Figure 14As shown, two positioning grooves 506 are symmetrically arranged at the bottom of the inner wall of the placement box 102. An mounting block 527 is fixedly installed on the side of the upper flip cover 101 facing the placement box 102. A connecting shaft 528 is rotatably mounted on the side of the mounting block 527. Two positioning rods 525 are symmetrically fixedly installed on the outer surface of the connecting shaft 528. The cross-sectional shape and size of the positioning rods 525 are consistent with the positioning grooves 506. Initially, the positioning rods 525 are in contact with the upper flip cover 101. When the positioning rods 525 rotate 90 degrees, they are positioned above the positioning grooves 506. When the lower end face of the upper flip cover 101 coincides with the upper end face of the placement box 102, the positioning rods 525 extend into the positioning grooves 506. At this time, the distance between the side of the positioning rods 525 and the inner wall of the placement box 102 is equal to that of the protective plate. The thickness of the 510 is equal. The positioning rod 525 has a fourth mounting groove 526 on its side. The inner wall of the fourth mounting groove 526 is attached with an iron sheet. The upper flip cover 101 is also fixedly installed on the side facing the placement box 102. A rotating rod 530 is rotatably installed on the outer surface of the limiting shaft 529. A second magnetic block 531 is fixedly installed at the end of the rotating rod 530 away from the limiting shaft 529. The second magnetic block 531 is made of magnet. When the side of the rotating rod 530 is perpendicular to the side of the positioning rod 525, the second magnetic block 531 extends into the fourth mounting groove 526 and fits against the iron sheet on the inner wall of the fourth mounting groove 526. The length of the fourth mounting groove 526 is greater than the length of the second magnetic block 531, and the width of the fourth mounting groove 526 is equal to the width of the second magnetic block 531.

[0031] As attached Figure 7 To the attached Figure 10 As shown, the thickness of the protective plate 510 is equal to the depth of the first mounting groove 501, the distance of the first limiting rod 519 toward the side of the placement box 102 is equal to the sum of the thicknesses of the protective plate 510 and the front protective plate 516, and the thickness of the front protective plate 516 is equal to the thickness of the side protective plate 512.

[0032] The working principle of this utility model is as follows: (a) When displaying, place the entire box 1 on an inclined display platform. Then push the handle 207 to drive the bending shaft 206 out of the arc-shaped hole of the positioning pin 205 through the bending rod 204. After that, the bending shaft 206 is separated from the positioning pin 205. Then rotate the upper flip cover 101 and the side flip cover 103. The upper flip cover 101 drives the positioning rod 525 out of the positioning groove 506. Then rotate the positioning rod 525. When the positioning rod 525 is in contact with the upper flip cover 101, stop rotating the positioning rod 525. At this time, rotate the rotating rod 530. When the second magnetic block 531 extends into the inner wall of the fourth mounting groove 526, stop rotating the rotating rod 530. The positioning rod 525 is limited by the second magnetic block 531.

[0033] (ii) Rotate all the hanging shafts 304. When the upper surface of the first magnetic block 305 is parallel to the upper surface of the placement box 102, stop rotating the hanging shafts 304. At this time, the hanging shafts 304 are tangent to the end face of the first mounting groove 302. Then, suspend the jewelry on the hanging shaft 304 closest to the placement groove 501. Then, place the other parts of the jewelry on the outer surface of the remaining hanging shafts 304 and support the jewelry through the remaining hanging shafts 304.

[0034] (ii) Then rotate all the positioning shafts 522 to release the second positioning block 524 through the release groove 521, thereby releasing the positioning shaft 522 from the first mounting hole 505, so that the first limiting rod 519 is no longer blocked. Then rotate the first limiting rod 519 to move the first limiting rod 519 away from the protective plate 510. Then rotate the protective plate 510 to gradually move the protective plate 510 closer to the display plate 301. Under the action of gravity, the side plate 512 and the front plate 516 begin to rotate, and under the action of the second positioning plate 517 and the first positioning plate 515, the positions of the side plate 512 and the front plate 516 are limited.

[0035] (III) When the upper surface of the protective plate 510 is parallel to the bottom of the inner wall of the placement box 102, the protective plate 510 contacts the upper surface of the first magnetic block 305. At this time, the two first limiting rods 519 below, which are close to the display tray 301, are rotated in the opposite direction, so that the first limiting rods 519 gradually fit against the side of the protective plate 510 away from the display tray 301. When the first limiting rods 519 coincide with the upper surface of the baffle 503, the rotation of the first limiting rods 519 is stopped. At this time, the positioning shaft 522 is reinserted into the first mounting hole 505. During this process, the second positioning block 524 passes through the release groove 5. 21. After the second positioning block 524 has completely passed through the release groove 521, rotate the positioning shaft 522 to move the second positioning block 524 away from the release groove 521. Thus, the positioning shaft 522 is limited by the second positioning block 524 and the first positioning block 523. At this time, the lower end face of the side guard plate 512 and the front guard plate 516 coincides with the bottom of the inner wall of the placement box 102. Thus, the jewelry is protected by the protective plate 510, the side guard plate 512, and the front guard plate 516, preventing people who are viewing the jewelry from directly touching it. People who are viewing the jewelry can view it through the display cover 511.

[0036] (III) After the display is completed, rotate the lower positioning shaft 522. When the second positioning block 524 coincides with the release groove 521, move the positioning shaft 522 to disengage it from the first mounting hole 505. Then, rotate the first limiting rod 519 in the opposite direction to disengage it from the protective plate 510. After that, rotate the protective plate 510 in the opposite direction. When the protective plate 510 rotates into the placement groove 501, the first positioning plate 515 and the second positioning plate 517 are respectively stored in the second mounting groove 508 and the third mounting groove 509. Then, rotate the side guard plate 512 and the front guard plate 516 to make them fit against the side of the protective plate 510 away from the placement groove 501. Then rotate... Move all the first limit rods 519 so that they re-fit the side of the protective plate 510 away from the placement groove 501. Stop rotating the first limit rods 519 when they coincide with the upper surface of the baffle 503. At this time, re-insert the positioning shaft 522 into the first mounting hole 505. During this process, the second positioning block 524 passes through the release groove 521. After the second positioning block 524 has completely passed through the release groove 521, rotate the positioning shaft 522 so that the second positioning block 524 moves away from the release groove 521. Thus, the positioning shaft 522 is limited by the second positioning block 524 and the first positioning block 523, and the positions of the side guard plate 512 and the front guard plate 516 are limited by the first limit rods 519.

[0037] (iv) Rotate the rotating rod 530, which drives the second magnetic block 531 to disengage from the fourth mounting slot 526. Then rotate the upper cover 101, which gradually moves closer to the placement box 102. At this time, the positioning rod 525 rotates under the action of gravity. When the lower end face of the upper cover 101 coincides with the upper end face of the placement box 102, the positioning rod 525 extends into the positioning slot 506, thereby limiting the position of the protective plate 510 through the positioning rod 525. Then rotate the side cover 103. When the side cover 103 coincides with the placement box 102, stop rotating the side cover 103.
