Background

The ring-shaped decorative elements worn by human bodies, such as rings, chain pendants and the like, are made of precious metals or precious stones and the like, and are popular with people since ancient times. The traditional annular decorative element is of a single structure and mainly comprises an annular body and a decorative part arranged on the annular body. For example, the upper ring-shaped decoration element has a single structure, and a plurality of ring-shaped decoration elements cannot be randomly combined to be different from other decoration elements, so that the requirement that people want to display themselves on the worn decoration element cannot be met, that is, the requirement that people pursue individuation cannot be met.

With the development of society, some decorative elements with replaceable decorative bodies appear, for example, the chinese patent No. 201720639784.1, the patent name detachable ring discloses a detachable structure (as shown in fig. 1 and fig. 2), which includes a ring holder and a ring, the ring holder 1 includes a left ring holder 10 and a right ring holder 11 that are arranged side by side from left to right, the left ring holder 10 includes a left ring body 100 and a left annular boss 101, the right ring holder 11 includes a right ring body 110 and a right annular boss 111, the left annular boss 101 surrounds an outer circumferential surface of a left end of the left ring body 100, the right annular boss 111 surrounds an outer circumferential surface of a right end of the right ring body 110, the left ring body 100 and the right ring body 110 are respectively provided with inner and outer threads that are in threaded engagement, the left ring body 100 and the right ring body 110 are screwed together through the inner and outer threads, so that the left ring body 100 and the right ring body 110 form a mounting groove, and the ring is mounted in the mounting groove. This solution has the following drawbacks: 1. when in assembly, the ring body is sleeved on one ring body, and then the other ring body passes through the ring body so as to be in threaded fit with the ring body in the ring. Because the ring body in the ring is sheltered by the ring, the thread opening is difficult to align, and the thread opening is easy to be damaged if the force is too large. 2. The replacement is comparatively single, and decorative relatively poor, and the left side is guarded against and is held in the palm and the right side is guarded against and hold in the palm more tends to the functionality, and decorative performance is poor, and the replacement part mainly is for guarding against the circle, even changed and guarded against the circle after, the outward appearance difference of ring is less, can not satisfy people's demand, also can not improve people's experience sense and satisfaction. 3. The adaptation degree is low, because two rings hold in the palm the recess that forms after connecting need with the width phase-match of ring, lead to two rings can not be general in various rings, if change the ring of different width, then need to change two rings of width assorted with it and hold in the palm, increased people's purchase cost. In summary, conventional decorative elements do not improve the experience and satisfaction of people.

Referring to fig. 3 to 5, the decoration element of the present application includes an inner ring 200, a first outer ring 300 annularly disposed at a first end of the inner ring 200, and a second outer ring 400 annularly disposed at a second end of the inner ring 200, wherein the first outer ring 300 and the second outer ring 400 are respectively annularly disposed at the first end and the second end of the inner ring 200 by a clamping manner. After the first outer ring 300 and the second outer ring 400 are annularly disposed on the inner ring 200, the inner ring 200 can be entirely covered in the axial direction, so that the inner ring 200 is hidden in the first outer ring 300 and the second outer ring 400. From the viewpoint of cost saving, the inner ring 200 may be made of a metal having light weight and oxidation resistance, for example, a metal material such as stainless steel or silver. First outer lane 300 and second outer lane 400 can adopt precious metal preparation such as gold, 18K gold, platinum to form, the part that can demonstrate of first outer lane 300 and second outer lane 400 can have diversified, beautifully designed, if can inlay elements such as precious stone, diamond, jade, like the diversified design that carved patterns etc. can give people the experience and the impression of beauty again. The displayable portions are typically the outer circumferential surfaces and/or noticeable end surfaces of the first outer ring 300 and the second outer ring 400.

The first end of the inner ring 200 is provided with a first clamping groove 20 and a first guide channel 21 communicated with the first clamping groove 20, and the first clamping groove 20 and the first guide channel 21 are both arranged on the outer surface of the inner ring 200 at a position close to the first end. The first outer ring 300 is correspondingly provided with a first buckle 30, and the first buckle 30 enters the first clamping groove 20 along the first guide channel 21 to be clamped in the first clamping groove 20. The first clamping groove 20 and the first guide channel 21 form a group of first clamping components, and a plurality of groups of the first clamping components can be uniformly arranged on the inner ring 200 at intervals along the circumferential direction; the first outer ring 300 is provided with a plurality of first fasteners 30 which are fastened with the plurality of first fastening components one by one.

The first guide passage 21 has a first inlet 211 for the first clip 30 to be inserted in along the axial direction of the inner ring 200, and a first guide through groove 212 extending from the first inlet 211 along the circumferential direction of the inner ring 200 to the direction of the first clip groove 20 and communicating therewith, and the first inlet 211 and the first guide through groove 212 both penetrate through the inner ring 200 outward along the radial direction of the inner ring 200.

The first inlet 211 is formed by a first end surface of the inner ring 200 being recessed toward the second end direction, a first opening 213 communicating with the first guiding through groove 212 is formed at a side of a bottom of the first inlet 211 facing the first clamping groove 20, a first guiding side surface 214 is formed at a side surface of the first inlet 211 away from the first opening 213, and the first guiding side surface 214 is formed by extending a bottom surface of the first inlet 211 obliquely toward the first end direction and toward a direction away from the first guiding through groove 212, so that a size of the first inlet 211 is gradually reduced toward the bottom direction of the first inlet 211. It should be noted that even the size of the bottom with the smallest size should be matched with the size of the first snap 30, so as to ensure that the first snap 30 can smoothly enter the first opening 213 from the bottom of the first inlet 211 and then enter the first card slot 20 through the first guiding through slot 212. The first guiding through groove 212 has a first groove bottom 215 recessed in the outer circumferential surface of the inner ring 200, a first guiding sidewall 216 near the first end of the inner ring 200, and a second guiding sidewall 217 disposed opposite to the first guiding sidewall 216. The size of the first guiding through groove 212 is also adapted to the size of the first buckle 30, that is, the distance between the first guiding sidewall 216 and the second guiding sidewall 217 and the depth of the first groove bottom 215 are both set according to the size of the first buckle 30, so that the first buckle 30 can smoothly pass through the first buckle 30, and the first buckle 30 cannot be separated from the first guiding through groove 212 due to the inappropriate size of the first guiding through groove 212.

The first card slot 20 includes a first card wall 201 formed at the end of the first guiding sidewall 216 and a second card wall 202 formed at the end of the second guiding sidewall 217. The distance between the first blocking wall 201 and the second blocking wall 202 is slightly smaller than the distance between the first guiding sidewall 216 and the second guiding sidewall 217, and the distance between the first blocking wall 201 and the second blocking wall 202 is required to be sufficient to block the first buckle 30 so that the first buckle 30 cannot easily separate from the first blocking slot 20 without the assistance of external force. In this embodiment, the first locking groove 20 penetrates the inner ring 200 along a radial direction of the inner ring 200. In some embodiments, the depth of the first card slot 20 may coincide with the first guide channel 212.

In an embodiment, since the first engaging groove 20 is disposed at the first end of the inner ring 200, the width of the first engaging wall 201 (i.e. the dimension of the first engaging wall 201 corresponding to the axial direction of the inner ring 200) is not too wide, that is, the first engaging wall 201 is a strip shape as a whole, and has a certain deformation force, so that when the first engaging groove 30 is squeezed into the first engaging groove 20, the deformation force makes the first engaging groove 20 slightly larger to be squeezed into the first engaging groove 30, and the clamping force of the first engaging groove 30 is maintained.

As a more preferable embodiment, please refer to fig. 1 and fig. 3, the first blocking wall 201 protrudes from the inner ring 200 to the first guiding sidewall 216, that is, the first blocking wall 201 is closer to the second end of the inner ring 200 than the first guiding sidewall 216 when viewed from the axial direction of the inner ring 200, so as to increase the width from the first blocking wall 201 to the first end surface of the inner ring 200 (hereinafter, referred to as the width of the first blocking wall 201), and prevent the first blocking wall 201 from being deformed by the first buckle 30. In this embodiment, in order to realize the expansion force of the first engaging groove 20, a first expansion auxiliary groove 203 is formed in the inner ring 200 at a position close to the second engaging wall 202 in parallel with the first expansion auxiliary groove, and the first expansion auxiliary groove 203 penetrates the inner ring 200 in the radial direction of the inner ring 200. A strip-shaped first extending deformation part 203a with a narrow width is formed between the first extending deformation auxiliary groove 203 and the second card wall 202, and the width of the first extending deformation part 203a is far smaller than the width of the first card wall 201, so that when the first buckle 30 is squeezed into the first card slot 20, the first buckle 30 squeezes the first extending deformation part 203a, so that the first card slot 20 can be deformed along with the first buckle 30 and can also be pressed against the first buckle 30.

Referring to fig. 5, the end (the end far from the first guiding through slot 212) of the second card wall 202 is connected to the end of the first card wall 201, so that the end of the first card slot 20 forms a first blocking end 204, and the first blocking end 204 prevents the first buckle 30 from advancing further and simultaneously limits the first buckle 30. The second chuck wall 202 has a first chuck tooth disposed thereon along a length direction thereof, the first chuck tooth is composed of a plurality of first tooth portions 205 connected end to end, and a first transition slot portion 206 is formed between every two adjacent first tooth portions 205. First latch breaks away from in traditional sawtooth structure, jumps out traditional thinking and is used to circle, is the wave shape by the design, and is promptly, every first tooth portion 205 (bulge) design is more level and smooth arch form, and the first transition slot part 206 design between the two adjacent first tooth portions 205 is more level and smooth concave arc form, makes first buckle 30 card is gone into more in the same direction as smooth during first draw-in groove 20, the interlock that concave-convex form also can be better first buckle 30 prevents first buckle 30 breaks away from first draw-in groove 20.

With reference to fig. 5, it is preferable that a first start tooth portion 205a of the front end of the first latch has a certain distance from the front end of the second latch wall 202, that is, the start of the first latch is not located at the same position as the start of the second latch wall 202, but behind the start of the second latch wall 202. A first start groove portion 206a is further engaged between the first start tooth portion 205a and the front end portion of the second chuck wall 202, and a gap between the first start groove portion 206a and the first chuck wall 201 is larger than a gap between the front end portion of the second chuck wall 202 and the first chuck wall 201. The design is ingenious in that: since the gap (hereinafter referred to as the first extrusion gap 207) between the front end portion of the second card wall 202 and the first card wall 201 is smaller than the gap between the first starting slot portion 206a and the first card wall 201, and the first extrusion gap 207 is smaller than the size of the first clip 30, when the first clip 30 enters the first card slot 20, a certain external force is applied to make the first clip 30 extrude into the first extrusion gap 207, and after passing through the first extrusion gap 207, the first clip 30 can enter the first latch portion to be engaged therewith, and without the assistance of a certain external force, the first clip 30 can not pass through the first extrusion gap 207 and leave the first card slot 20. When the first clip 30 passes through the first extrusion gap 207, the first clip 30 extrudes the first extensional deformation portion 203a towards the first extensional deformation auxiliary groove 203, and the first extensional deformation portion 203a is elastically deformed by extension, so that the first clip 30 smoothly enters to be engaged with the first latch while being extruded.

A second clamping groove 20' and a second guiding channel 21' communicated with the second clamping groove 20' are arranged at a second end of the inner ring 200, and the second clamping groove 20' and the second guiding channel 21' are both arranged on the outer surface of the inner ring 200 at positions close to the second end. The second outer ring 400 is correspondingly provided with a second buckle 40, and the second buckle 40 enters the second card slot 20' along the second guide channel 21' to be clamped in the second card slot 20'. The second clamping grooves 20 'and the second guide channels 21' form a group of second clamping components, and a plurality of groups of such second clamping components can be uniformly arranged on the inner ring 200 at intervals along the circumferential direction; the second outer ring 400 is provided with a plurality of second fasteners 40 in a one-to-one correspondence, and the plurality of sets of second fastening components are fastened one by one. The second card slot 20' and the second guiding channel 21' have the same or similar structure, size, arrangement position and function as the first card slot 20 and the second guiding channel 21 '.

Specifically, the second guiding channel 21' has a second inlet 211' for the second snap 40 to be inserted in the axial direction of the inner ring 200, and a second guiding through groove 212' extending from the second inlet 211' in the circumferential direction of the inner ring 200 toward the second snap groove 20' and communicating therewith, and both the second inlet 211' and the second guiding through groove 212' penetrate through the inner ring 200 outward in the radial direction of the inner ring 200.

The second inlet 211' is formed by recessing the second end surface of the inner ring 200 toward the first end, a second opening 213' communicating with the second guiding groove 212' is formed at a side of the bottom of the second inlet 211' facing the second locking groove 20', a second guiding side surface 214' is formed at a side of the second inlet 211' away from the second opening 213', and the second guiding side surface 214' is formed by extending the bottom surface of the second inlet 211' obliquely toward the second end direction and away from the second guiding channel 21', so that the size of the second inlet 211' is gradually reduced toward the bottom of the second inlet 211 '. It should be noted that even the smallest bottom should be sized to fit the size of the second clip 40, so as to ensure that the second clip 40 can smoothly enter the second opening 213 'from the bottom of the second inlet 211' and then enter the second card slot 20 'through the second guiding through slot 212'. The second guiding through groove 212 'has a second groove bottom recessed in the outer circumferential surface of the inner ring 200, a third guiding sidewall 216' adjacent to the second end of the inner ring 200, and a fourth guiding sidewall 217 'disposed opposite to the third guiding sidewall 216'. The size of the second guiding through groove 212 'is also adapted to the size of the second clip 40, that is, the distance between the third guiding sidewall and the fourth guiding sidewall 217' and the depth of the bottom of the second groove are both set according to the size of the second clip 40, so that the second clip 40 can smoothly pass through the second clip 40, and the second clip 40 cannot be separated from the second guiding through groove 212 'due to the improper size of the second guiding through groove 212'.

The second card slot 20' includes a third card wall 201' formed at the end of the third guiding sidewall 216' and a fourth card wall 202' formed at the end of the fourth guiding sidewall 217'. The distance between the third clip wall 201' and the fourth clip wall 202' is slightly smaller than the distance between the third guiding sidewall 216' and the fourth guiding sidewall 217', and the distance between the third clip wall 201' and the fourth clip wall 202' is required to be able to clip the second clip 40 so that the second clip cannot easily disengage from the second clip groove 20' without the assistance of external force. In this embodiment, the second locking groove 20' penetrates the inner ring 200 along the radial direction of the inner ring 200. In some embodiments, the depth of the second card slot 20 'may coincide with the second guiding channel 212'.

In an embodiment, since the second engaging groove 20 'is disposed at the second end of the inner ring 200, the width of the third engaging wall 201' (i.e. the dimension of the third engaging wall 201 'corresponding to the axial direction of the inner ring 200) is not too wide, that is, the third engaging wall 201' is a strip shape as a whole and has a certain expansion deformation force, so that when the third engaging groove is squeezed into the second engaging groove 20', the expansion deformation force makes the second engaging groove 20' slightly larger to be squeezed into the second engaging groove 40, and maintains the clamping force of the second engaging groove 40.

As a more preferable embodiment, please refer to fig. 3 and fig. 5, the second blocking wall 202 protrudes from the inner ring 200 axially to the third guiding sidewall 216', that is, the third blocking wall 201' is closer to the first end of the inner ring 200 than the third guiding sidewall 216 'when viewed from the axial direction of the inner ring 200, so that the width from the third blocking wall 201' to the second end surface of the inner ring 200 (hereinafter referred to as the width of the third blocking wall 201 ') can be increased to prevent the third blocking wall 201' from being deformed by the second buckle 40. In this embodiment, in order to realize the expansion force of the second engaging groove 20', a second expansion auxiliary groove 203' is formed in the inner ring 200 at a position close to the fourth engaging wall 202 'in parallel with the first expansion auxiliary groove, and the second expansion auxiliary groove 203' penetrates the inner ring 200 in the radial direction of the inner ring 200. A strip-shaped second extended deformation part 203a 'with a narrower width is formed between the second extended deformation auxiliary groove 203' and the fourth card wall 202', and the width of the second extended deformation part 203a' is much smaller than the width of the third card wall 201', so that when the second buckle 40 is squeezed into the second card groove 20', the second buckle 40 squeezes the second extended deformation part 203a ', so that the second card groove 20' can be deformed along with the second buckle 40 and can also be tightly pressed against the second buckle 40.

With continued reference to fig. 5, the end of the fourth card wall 202 '(the end away from the second guiding through slot 212') is connected to the end of the third card wall 201 'so that the end of the second card slot 20' forms a second blocking end, and the second blocking end prevents the second buckle 40 from further advancing while limiting the second buckle 40. The fourth chuck wall 202' has a second chuck tooth disposed thereon along the length direction thereof, the second chuck tooth is composed of a plurality of second tooth portions connected end to end, and a second transition groove portion is formed between every two adjacent second tooth portions. The second latch breaks away from in traditional sawtooth structure, jumps out traditional thinking and is used to circle, is designed to be the wave shape, promptly, and every second tooth portion (bulge) designs for more level and smooth arch form, and the second transition slot part between two adjacent second tooth portions designs for more level and smooth concave arc form, makes second buckle 40 card is gone into more in the same direction as smooth when the second draw-in groove 20', interlock that unsmooth form also can be better second buckle 40 prevents second buckle 40 breaks away from second draw-in groove 20'.
