Description

Technical Field

[0001] This utility model belongs to the field of decorative arts, specifically a mother-and-child crystal box. Background Technology

[0002] Traditional crystal ornaments, such as crystal pendants, are usually made by directly gluing the crystal to the box. This method of fixing mainly relies on the adhesive strength.

[0003] However, this traditional adhesive bonding method has many drawbacks: First, the adhesive joint is prone to cracking when subjected to external impact, vibration, or temperature changes, causing the crystal to loosen or even fall off, resulting in poor product reliability; second, once the crystal falls off due to adhesive failure, re-fixing it is very difficult, requiring cleaning of residual adhesive and re-application, making repairs inconvenient and essentially an irreversible assembly. It cannot meet the growing usage needs of consumers.

[0004] In view of this, a mother-and-child crystal box is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a mother-and-child crystal box in order to solve the problems mentioned above.

[0006] The technical solution adopted by this utility model is as follows: A mother-daughter crystal box includes a mother box and a daughter box, wherein the daughter box is detachably installed on the mother box. Both the mother box and the daughter box have receiving cavities along the coaxial direction. Crystals are respectively housed in the receiving cavities of the mother box and the daughter box. Positioning members are respectively embedded in the mother box and the daughter box. The opposing end faces of the two positioning members abut against the opposing end faces of the two crystals. The inner edges of the mother box and the daughter box extend inward in opposite directions to form a retaining ring. The inner wall surface of the retaining ring abuts against the outer edge of the crystal to limit the position of the crystals in the mother box and the daughter box.

[0007] In a preferred embodiment, the connection between the crystal and the mother box and the daughter box is fixed by adhesive bonding.

[0008] In a preferred embodiment, the inner walls of the mother box and the daughter box are recessed inward to form a slot, the positioning member is partially embedded in the slot, and the inner edge of the crystal body abuts against the portion of the positioning member that protrudes outside the slot.

[0009] In a preferred embodiment, the mother box, the daughter box, and the two crystals together form a closed containment space.

[0010] In a preferred embodiment, the inner wall surface of the end of the mother box facing away from the crystal is provided with an internal thread, and the daughter box is provided with an external thread coupled to the internal thread.

[0011] In a preferred embodiment, the outer diameter of the main body of the sub-box is the same as the outer diameter of the main box.

[0012] In a preferred embodiment, the side wall of the mother box is provided with a hanging ear with a hanging hole.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, a positioning component for additional positioning of the crystal is provided in the box. During the process of assembling the crystal into the box, the positioning component can limit the crystal from the inside axially, which can realize a dual fixing mechanism of positioning component positioning and glue bonding. This can ensure that the crystal is firmly and stably embedded in the box, avoiding the problem of easy detachment caused by using glue bonding alone. 2. In this utility model, when the mother and child boxes are connected by threads, the two crystals are placed opposite each other and together with the box body form a completely enclosed storage space, which is very suitable for storing decorative items that users want. Since the two can be disassembled and assembled, different decorative items can be selected to be placed according to different usage scenarios, which increases the fun and practicality of the product.

Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0019] Reference Figure 1-5 A mother-and-child crystal box includes a mother box 200 and a child box 100, wherein the child box 100 is detachably mounted on the mother box 200. Both the mother box 200 and the child box 100 have receiving cavities 220 along a coaxial direction. Crystals 300 are respectively housed within the receiving cavities 220 of the mother box 200 and the child box 100. Positioning members 400 are respectively embedded within the mother box 200 and the child box 100. Retaining rings 250 extend inward from the inner edges of the mother box 200 and the child box 100 in opposite directions, with the inner wall surface of the retaining rings 250 abutting against the outer edge of the crystals 300. The opposite end faces of the two positioning members 400 respectively contact the two crystals 300. The opposite end faces of the crystal 300 abut against each other to define the positions of the crystal 300 in the mother box 200 and the daughter box 100, respectively. The connection between the crystal 300 and the mother box 200 and the daughter box 100 is fixed by adhesive bonding. A positioning member 400 for positioning the crystal 300 is provided in the box. During the assembly of the crystal 300 into the box, the positioning member 400 can limit the crystal 300 axially from the inside, and the retaining ring 250 can limit the crystal 300 radially from the outside. This can realize a dual fixing mechanism of mechanical positioning and adhesive positioning, ensuring that the crystal 300 is firmly and stably embedded in the box, avoiding the problem of easy detachment caused by using adhesive bonding alone.

[0020] It should be mentioned that the shapes of the mother box 200 and the daughter box 100 can be adjusted according to different usage scenarios. In this embodiment, the mother box 200 and the daughter box 100 are circular. In other embodiments, the mother box 200 and the daughter box 100 can also be square, polygonal, or other shapes. When they are square, polygonal, or other shapes, the shapes of the crystal 300, the retaining ring 250, and the positioning member 400 also change accordingly (i.e., they correspond to the shapes of the mother box 200 and the daughter box 100), which will not be described in detail here.

[0021] The mother box 200 and the daughter box 100 are preferably made of metal, and the crystal 300 can be made of transparent or translucent materials such as glass, acrylic or artificial crystal, but there are no restrictions on these materials.

[0022] In this embodiment, please refer to Figures 2-5 As shown, the inner walls of the mother box 200 and the daughter box 100 are recessed inward to form a groove 230. The positioning member 400 is partially embedded in the groove 230, and the inner edge of the crystal 300 abuts against the portion of the positioning member 400 protruding from the groove 230. Specifically, the shape of the positioning member 400 corresponds to the shape of the groove 230. When the groove 230 is annular, the positioning member 400 is also annular; when the groove 230 is square, the positioning member 400 is also square. Preferably, the positioning member 400 is made of steel wire or plastic, but this is not limited. Due to the deformation capability of the positioning member 400 itself, after the crystal 300 is assembled into the receiving cavity 220, the positioning member 400 can be correspondingly embedded in the groove 230, thereby using the positioning member 400 to help limit the position of the crystal 300.

[0023] In addition, to facilitate the assembly of the positioning component 400, a notch may be reserved on the positioning component 400, but this is not a limitation.

[0024] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the mother box 200, the daughter box 100, and the two crystals 300 together form a closed storage space 500. The inner wall of the end of the mother box 200 facing away from the crystals 300 is provided with an internal thread 240, and the daughter box 100 is provided with an external thread 110 that couples with the internal thread 240. When the mother and daughter boxes are connected by threads, the two crystals 300 are placed opposite each other, forming a completely closed storage space together with the box body. This is very suitable for storing decorative items (not shown in the figure) that users want. Since both can be disassembled and assembled, different decorative items can be placed according to different usage scenarios, which increases the fun and practicality of the product. It also allows for the replacement of individual parts, which can save on overall maintenance and replacement costs.

[0025] Of course, in other embodiments, the mother box 200 and the daughter box 100 may also adopt other fixing methods such as snap-fit ​​structure, which are not limited here.

[0026] Furthermore, the outer diameter of the main body of the sub-box 100 is the same as the outer diameter of the main body of the mother box 200, making the overall appearance of the assembled box smooth and unified, and more aesthetically pleasing.

[0027] In this embodiment, please refer to Figure 1 and Figure 3 As shown, the side wall of the mother box 200 is provided with a hanging ear 210 with a hanging hole. The hanging ear 210 on the mother box 200 is designed to be easily hung up as a decoration or display item, thus expanding its usage scenarios. Preferably, the hanging ear 210 and the mother box 200 are integrally molded, which saves on mold opening costs while ensuring the combined strength of the connection between the hanging ear 210 and the mother box 200.

[0028] The specific assembly process is as follows: two crystals 300 are embedded in the receiving cavity 220 from the inside out. A layer of glue is applied at the connection position between the edge of the crystal 300 and the box body. Then, the corresponding positioning part 400 is snapped into the slot 230. The crystals 300 can be double-fixed by the glue (not shown in the figure) and the positioning part 400. Then, decorative items can be inserted into the cavity in the mother box 200 (different decorations can be put in according to user needs). Finally, the mother box 200 and the daughter box 100 are screwed together to complete the overall assembly of a product.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
