Description

Technical Field

[0001] The invention relates to the technical field of jewelry, in particular to a multi-purpose necklace decorative pendant. Background Art

[0002] Jewelry, originally referring to ornaments worn on the head, now widely refers to hairpins, earrings, necklaces, rings, bracelets, etc. made of precious metals and gemstones. Jewelry is generally used to decorate the human body. In a broad sense, jewelry refers to ornaments made of various metal materials, gemstones, organic materials and imitations to decorate the human body and its related environment. It can be seen that jewelry in a broad sense has included some scopes of jewelry, accessories and ornaments, or the three have become one, which is the development direction of the jewelry industry today.

[0003] Most of the existing necklace pendants are fixed on the necklace and are integrated with the necklace. They cannot be replaced, and the necklace cannot be replaced with pendants of different styles. For the few necklaces with replaceable pendants, the pendants no longer have other uses after being replaced, so the pendants can no longer be used and have a single purpose.

[0004] In view of the above problems, the present invention provides a multi-purpose necklace decorative pendant. Summary of the invention

[0005] The object of the present invention is to provide a multi-purpose necklace decorative pendant, comprising a decorative plug unit and a connecting base unit. The decorative plug unit is movably mounted on the connecting base unit, so as to facilitate the replacement of the decorative pendant of the necklace, and the replaced decorative pendant can also be used for other purposes, thus changing the original single purpose, thereby solving the problems in the background technology.

[0007] The connecting base unit is provided with an upper magnetic connecting block, a lower support seat and a fixing pin. The lower support seat is provided with two groups. The lower support seats of the two groups are fixedly arranged on the lower end surface of the upper magnetic connecting block to form a connecting base unit as a whole. The fixing pins are movably plugged into the lower support seats of the two groups. The lower support seat is provided with a first base block and a first support block. The lower end of the first support block is fixedly arranged on one side of the upper end surface of the first base block to form a lower support seat as a whole, and the upper end of the first support block is fixedly connected to the lower end surface of the upper magnetic connecting block.

[0008] Furthermore, the fixed inlay seat is a component made of iron material and has a circular structure, and is provided with a covering frame edge and a decorative inlay. The covering frame edge is arranged on both sides of the fixed inlay seat, and the decorative inlay is fixedly inlaid on the side of the fixed inlay seat where no magnet is arranged.

[0009] Furthermore, the decorative plug unit is also provided with hemispherical snap-fitting protrusions, and two groups of hemispherical snap-fitting protrusions are provided. The two groups of hemispherical snap-fitting protrusions are fixedly arranged on the inner side of the covering frame edge.

[0010] Furthermore, the upper magnetic connection block is a component made of iron material and has a circular structure, and is provided with jacks A. Two groups of jacks A are provided, and the two groups of jacks A are opened at both ends of the upper magnetic connection block.

[0011] Furthermore, the first base block is an elliptical structure, and the bottom surface is a planar structure, and is provided with a positioning slot A, which is fixedly opened on the upper end surface of the first base block, and a socket B is opened at the lower end of the first support block arranged on the upper end surface of the first base block, and a connecting groove is formed between the two groups of first support blocks.

[0012] Furthermore, the connection base unit is also provided with an elliptical magnetic connection block and a reinforcement support seat. Two groups of elliptical magnetic connection blocks are provided. The two groups of elliptical magnetic connection blocks are fixedly arranged on the upper end of the reinforcement support seat to form the connection base unit as a whole.

[0013] Furthermore, the reinforced support seat is provided with a second base block, a second support block and a connecting cross block. The second base block is an elliptical structure, and the bottom surface is an arc surface structure. A slot B is provided on the upper end surface of the second base block. The second support block is fixedly arranged on the upper end surface of the second base block. The connecting cross block is fixedly arranged between the two groups of second base blocks, and a snap-fit ​​positioning groove is provided on the upper end surface of the connecting cross block.

[0014] Furthermore, the elliptical magnetic connection block is provided with a socket C and a hemispherical engaging groove, the socket C is arranged at one end of the elliptical magnetic connection block, and the hemispherical engaging groove is arranged on the side of the elliptical magnetic connection block.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The multi-purpose necklace decorative pendant provided by the present invention has a fixed inlay seat provided with a magnet movably installed on the connecting base unit through an insertion pin, and a socket A is provided on the upper magnetic connection block of the connecting base unit, and a positioning slot A and a socket B are respectively provided on the first base block and the first support block of the lower support seat. When in use, the necklace is placed in the connecting slot formed between the two groups of first support blocks, and then the fixing pin is plugged into the first support block through the socket B, and the connecting slot is blocked to hang the decorative pendant on the necklace, so that the decorative pendant can be replaced. The connection is completed by adsorption of the magnet with the upper magnetic connection block at the upper end of the connecting base unit. After the pin is inserted into the positioning slot A, it can resist the fixing pin inserted into the socket B, which can effectively prevent the fixing pin from falling off from the socket B. At the same time, the fixed inlay seat provided with the decorative inlay can also be replaced with the connecting base unit, which is convenient for replacing decorative inlays of different styles.

[0017] 2. The multi-purpose necklace decorative pendant provided by the present invention can be connected to a ring through the connecting notch after the decorative pendant is replaced from the necklace. The ring is placed in the connecting notch of the lower support seat, and the fixing pin is then plugged into the first support block through the socket B to fix the ring, so that the decorative pendant can be used not only to decorate the necklace but also to decorate the ring, thereby increasing its uses. At the same time, when the pin is inserted into the connecting base unit, placement notches are formed on both sides of the lower support seat, and the removed ring can also be placed in the placement grooves on both sides of the lower support seat, and then the decorative pendant can be fixed on the necklace, thereby increasing the aesthetics of the decorative pendant and also completing the storage of the removed ring.

[0018] 3. The multi-purpose necklace decorative pendant provided by the present invention has a connecting cross block with a snap-fitting positioning groove fixedly welded between the second base blocks. Compared with inserting a fixing pin into the first support block to fix the necklace or ring, the connecting cross block fixes the necklace or ring in the connecting groove in a simpler and more secure manner. At the same time, a hemispherical snap-fitting protrusion is fixedly set on the inner side of the covering frame edge, and a hemispherical snap-fitting groove is opened on the side of the elliptical magnetic connection block. The hemispherical snap-fitting protrusion is snap-fitted and connected with the hemispherical snap-fitting groove, so that the connection between the decorative plug unit and the connecting base unit is more secure, which can effectively prevent the decorative plug unit from falling off the connecting base unit. At the same time, the lower end surface of the second base block is set to an arc surface structure, so that the contact between the second base block and the finger is more consistent, which makes it easier for the ring to be worn on the finger after the decorative pendant is installed.
