[0038] like Figures 1-3 As shown, an interior decoration installation structure for a modular pendant includes a pendant body 10, a decorative item 12, a pendant cover 13, and a rotating part 14. When assembled, the overall shape is elliptical. The pendant body 10 has a decoration cavity 11. The pendant cover 13 is hinged to the pendant body 10 and can be opened or closed. A first glass cover is provided on one side wall of the decoration cavity 11, and a second glass cover is installed on the pendant cover 13. The decoration inside the decoration cavity 11 can be seen through the first and second glass covers. When the pendant cover 13 is closed, the first and second glass covers are symmetrically arranged with respect to the axis of the modular pendant. The rotating part 14 is installed at one end of the pendant body 10, and the decorative item 12 is detachably installed in the decoration cavity 11.

[0039] In one embodiment, the rotating part 14 is frustum-shaped, and a frustum cavity 41 is formed on the rotating part 14. A connecting sleeve 27 is installed in the frustum cavity 41. The connecting sleeve 27 is cylindrical, and two protruding blocks 28 are fixed on the circumferential side of the connecting sleeve 27, which are symmetrically arranged with respect to the axis of the connecting sleeve 27. Two snap-fit ​​grooves 42 are formed on the end face of the rotating part 14 near the pendant body 10, which are symmetrically arranged with respect to the axis of the rotating part 14. The protruding blocks 28 can be slidably inserted into the snap-fit ​​grooves 42, and the outline size of the protruding blocks 28 is adapted to the outline size of the snap-fit ​​grooves 42. On the one hand, the snap-fit ​​grooves 42 and the protruding blocks 28 are set to facilitate the positioning and assembly of the rotating part 14 and the connecting sleeve 27. On the other hand, when the rotating part 14 rotates, the snap-fit ​​grooves 42 can push the protruding blocks 28 to rotate, thereby driving the 27 to rotate.

[0040] In one embodiment, a connecting block 38 is also installed inside the frustum cavity 41. Two positioning blocks 36 are fixed on the top surface of the connecting block 38. Two positioning grooves 29 are provided on the end face of the connecting sleeve 27 near the rotating part 14, which are symmetrically arranged with respect to the axis of the connecting sleeve 27. The positioning blocks 36 can be quickly inserted into the positioning grooves 29. The connecting block 38 and the connecting sleeve 27 are fixed together by welding.

[0041] In one embodiment, the connecting sleeve 27 has an installation groove 31. The installation groove 31 is fully open at one end near the rotating part 14, and a circular hole 44 is provided at the other end. The diameter of the circular hole 44 is smaller than that of the installation groove 31, which is used to insert the connecting shaft 19 and subsequently install the spring body 32. Two sliding grooves 30 are provided on the side wall of the installation groove 31, which are symmetrically arranged with respect to the axis of the connecting sleeve 27. The length of the sliding grooves 30 is less than the length of the connecting sleeve 27. The line connecting the two sliding grooves 30 is orthogonal to the line connecting the two protrusions 28.

[0042] In one embodiment, a mating groove 43 is provided on the top surface of the connecting block 38, and two small grooves 37 are provided on the side wall of the mating groove 43. The line connecting the two small grooves 37 is orthogonal to the line connecting the two positioning blocks 36. When the connecting block 38 is fixed together with the connecting sleeve 27, the two small grooves 37 and the two sliding grooves 30 coincide in the axial direction of the connecting sleeve 27, so that the small grooves 37 can communicate with the sliding grooves 30. This facilitates the subsequent assembly, where the fixing strip 24 and the guide slider 33 slide in the small grooves 37 and the sliding grooves 30, so that when the rotating part 14 rotates, it slightly disengages from the pendant body 10 and is then bounced back by the spring body 32.

[0043] In one embodiment, a small sleeve 35 is placed on the mating groove 43. The small sleeve 35 is cylindrical. Two guide sliders 33 are provided on the circumferential side of the small sleeve 35, which are symmetrical with respect to the axis of the small sleeve 35. The small sleeve 35 is hollow and extends vertically. Two limiting grooves 34 are formed on the end face of the small sleeve 35 near the connecting block 38. The two limiting grooves 34 are symmetrical with respect to the axis of the small sleeve 35. The line connecting the two limiting grooves 34 is parallel to the line connecting the two guide sliders 33.

[0044] During installation, insert the small sleeve 35 into the mounting groove 31 and insert the guide slider 33 into the sliding groove 30.

[0045] In one embodiment, the jewelry cavity 11 has a through hole 26 at one end along the axis of the combined pendant. A connecting shaft 19 is inserted into the through hole 26 along the axis of the combined pendant. A cross block 16 is fixed to one end of the connecting shaft 19. The connecting shaft 19 is inserted into the connecting sleeve 27 through the through hole 26, and then into the small sleeve 35, so that the small sleeve 35 is fitted onto the connecting shaft 19. Two fixing strips 24 are fixed to the other end of the connecting shaft 19, which are symmetrically arranged with respect to the axis of the connecting shaft 19. After the connecting shaft 19 is inserted into the connecting sleeve 27 and the small sleeve 35 is fitted onto the connecting shaft 19, the two fixing strips 24 are fixed by welding. The two fixing strips 24 are respectively inserted into two limiting grooves 34.

[0046] In one embodiment, the cross block 16 is in the shape of a cross, and the edges of the cross block 16 are chamfered to eliminate sharp edges. A connecting groove 40 is provided on one side of the decorative item 12. The connecting groove 40 is divided into two parts. One part is in the shape of a cross, which is called the cross-shaped part in this embodiment. The cross-shaped part matches the outline size of the cross block 16. The other part is circular, which is called the circular part. The circular part is located on the inner side, and the cross-shaped part is located on the outer side.

[0047] In one embodiment, a plurality of fixed inclined blocks 25 are fixed on one end face of the pendant body 10 with a through hole 26, and are evenly arranged in a circular shape. In this embodiment, four fixed inclined blocks 25 are provided. The side of the fixed inclined block 25 away from the pendant body 10 is an inclined surface. A plurality of inclined grooves 39 are provided on the side face of the rotating part 14 near the pendant body 10. In this embodiment, the number of inclined grooves 39 is twice that of the fixed inclined blocks 25, that is, eight. The side of the inclined grooves 39 away from the pendant body 10 is also an inclined surface. The size and contour of the inclined grooves 39 are adapted to the size and contour of the fixed inclined blocks 25, so that the inclined grooves 39 can slide and engage with the fixed inclined blocks 25 through the inclined surface.

[0048] In one embodiment, a snap button 15 is slidably mounted on the pendant body 10, a snap spring 17 is mounted on the snap button 15, and a snap hole 18 is provided on the pendant body 10. The snap hole 18 communicates with the groove on which the snap button 15 is mounted. A hinge groove 22 is provided on the pendant body 10, and a hinge block 23 is fixed on the pendant cover 13. The hinge block 23 is hinged in the hinge groove 22. Two top opening plates 21 are slidably mounted on the pendant body 10, and a small spring 20 is installed between the top opening plate 21 and the pendant body 10. A hook 45 is fixed on the pendant cover 13, and the snap button 15 has an opening that can coincide with the snap hole 18.

[0049] Specifically, when the pendant cover 13 is closed, the hook 45 is inserted into the buckle hole 18 and into the opening on the buckle button 15. Due to the elastic force of the buckle spring 17, the buckle button 15 squeezes and locks the hook 45, thereby closing the pendant cover 13 and fastening it to the pendant body 10. Pressing the buckle button 15 releases the hook 45, and the top opening plate 21 pushes the pendant cover 13 open under the action of the small spring 20.

[0050] In one embodiment, a mating block 46 is fixed on one side wall of the jewelry cavity 11 near the cross block 16. The mating block 46 is also cross-shaped, and its outline size matches the cross-shaped part of the connecting groove 40. It is used to install the ornament 12 on the mating block 46. A through hole 47 is provided in the middle of the mating block 46. The through hole 47 is coaxially arranged with the combined pendant. The diameter of the through hole 47 is slightly larger than the diameter of the connecting shaft 19 and smaller than the outline size of the cross block 16, preventing the cross block 16 from detaching downward from the pendant body 10.

[0051] In one embodiment, a spring body 32 is provided in the mounting groove 31, and the spring body 32 is sleeved on the connecting shaft 19.

[0052] The assembly method of the interior mounting structure of a modular pendant is as follows:

[0053] First, insert the connecting shaft 19 into the through hole 47 from the jewelry cavity 11. The bottom of the connecting shaft 19 extends out of the pendant body 10, and the other part is located in the jewelry cavity 11. First, put the connecting sleeve 27 on a part of the bottom of the connecting shaft 19. Then, install the spring body 32 into the mounting groove 31 so that the spring body 32 is on the connecting shaft 19. Then, put the small sleeve 35 on the connecting shaft 19. Align the guide slider 33 with the slide groove 30 and push the small sleeve 35 into the mounting groove 31. The top of the small sleeve 35 abuts against the spring body 32. At this time, insert the two fixing strips 24 into the two limiting grooves 34. Then, weld the fixing strips 24 and the connecting shaft 19 to fix the fixing strips 24 and the connecting shaft 19. Then, connect the connecting block 38 with the connecting sleeve 27 so that the positioning block 36 is inserted into the positioning groove 29. Weld the positioning block 36 and the positioning groove 29 to fix them, thereby fixing the connecting sleeve 27 and the connecting block 38.

[0054] Then, the rotating part 14 is fixed to the connecting sleeve 27, the connecting sleeve 27 is inserted into the frustum cavity 41, and the protruding block 28 is installed into the snap-fit ​​groove 42. The protruding block 28 and the snap-fit ​​groove 42 are welded and fixed.

[0055] At this time, the connecting shaft 19 can move up and down a small distance relative to the connecting sleeve 27 and the rotating part 14 that are welded together, but the connecting shaft 19 cannot rotate relative to the connecting sleeve 27 and the rotating part 14.

[0056] Then, the connecting shaft 19 is inserted into the through hole 26, so that the top of the connecting shaft 19 passes through the through hole 47 and enters the jewelry cavity 11. The fixing wedge 25 is inserted into the inclined groove 39, and then the cross block 16 is welded to the top of the connecting shaft 19.

[0057] Then align the connecting groove 40 of the ornament 12 with the cross block 16, so that the cross-shaped part of the connecting groove 40 coincides with the cross block 16. Press down on the ornament 12 so that the cross block 16 extends into the circular part of the connecting groove 40. At the same time, the cross-shaped part of the connecting groove 40 covers the mating block 46. At this time, rotate the rotating part 14 to drive the cross block 16 to rotate, so that the cross block 16 and the cross part of the connecting groove 40 no longer coincide.

[0058] Then, the hinge block 23 is installed into the hinge groove 22, the buckle button 15 is installed onto the pendant body 10, the pendant cover 13 is placed on the pendant body 10, the hook 45 is inserted into the buckle hole 18 and is held in place by the buckle button 15, thus completing the assembly.

[0059] When it is necessary to replace or remove the ornament 12, press the buckle button 15 to open the pendant cover 13, and then rotate the rotating part 14. Since the fixed inclined block 25 and the inclined groove 39 are in inclined engagement, when rotating the rotating part 14, the rotating part 14 will disengage from the pendant body 10 by a small distance. This distance is determined by the depth of the inclined groove 39 and the size of the fixed inclined block 25. When the rotating part 14 rotates, the spring body 32 presses against the small sleeve 35, and the other end presses against the connecting sleeve 27, thereby causing the rotating part 14 to tend to move closer to the pendant body 10. When rotating the rotating part 14, due to the inclined block 25 and the inclined groove 39... With the inclined surface engaged, the rotating part 14 first moves away from the pendant body 10, and then, under the tension of the spring body 32, moves closer to the pendant body 10. This causes the fixing inclined block 25 to enter from one of the inclined grooves 39 into the adjacent inclined groove 39. At this time, the cross block 16 coincides with the cross-shaped part of the connecting groove 40, so that the connecting groove 40 can be removed. If it is not removed, it is rotated again so that when the fixing inclined block 25 enters from one of the inclined grooves 39 into the next adjacent inclined groove 39, the cross block 16 does not coincide with the cross-shaped part of the connecting groove 40, preventing the ornament 12 from detaching from the cross block 16.

[0060] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0061] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0062] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
