Description

Technical Field

[0001] The utility model relates to the technical field of jewelry design, in particular to a jewelry lock and a bracelet. Background Art

[0002] With the rapid development of the Internet, the emotional connection between people has decreased, and emotional values ​​are becoming increasingly difficult to satisfy. The demand for jewelry purchases is no longer limited to beautiful decorations, but needs to focus on emotional expression. For example, people's demand for jewelry is not limited to beauty and value, but they desire a piece of jewelry to have special meaning, especially in relationships between men and women or family relationships. Jewelry is usually used as a token of emotion, and connecting parts of a piece of jewelry between two people or members of a group is usually believed to form a perfect meaning and satisfy people's wishes for emotional relationships. However, the most important thing about the connection between jewelry is the stability of the connection. People may regard the stability of the connection as emotional stability. The lock design that connects jewelry has become a key difficulty in modular jewelry.

[0003] In addition, gold accounts for an increasingly larger share of the jewelry market. However, the design of gold jewelry is limited by its relatively soft material, and it is difficult to fully apply the link structure of K-gold material. This leads to the market usually forming gold jewelry into one piece to reduce the connection of gold material. Therefore, the field is in urgent need of a connecting lock suitable for highly ductile materials. Utility Model Content

[0004] In view of this, an object of the present invention is to provide a jewelry lock, aiming to solve the problem of low connection stability of high-ductility metals.

[0029] First embodiment

[0030] Please refer to Figure 1-3The utility model provides a jewelry lock 100 for connecting a first section 200 and a second section 300 of modular jewelry, including a first locking member 10 and a second locking member 20. The first locking member 10 includes a first base 11, a first plug rod 12 and a second plug rod 13. The first base 11 is used to connect the first section 200, and the first plug rod 12 is connected to the first base 11; the second locking member 20 includes a second base 21 and an elastic base 22. The second base 21 is used to connect the second section 300. The second base 21 is provided with a first limiting groove 211, a second limiting groove 212 and a third limiting groove 213. The first limiting groove 21 1 is used to be plugged with the first plug rod 12, the second limiting groove 212 is used to be plugged with the second plug rod 13, the groove depth direction 21X of the second limiting groove 212 is perpendicular to the groove depth direction 21Y of the third limiting groove 213, the third limiting groove 213 is connected with the first limiting groove 211, the elastic seat 22 is arranged in the third limiting groove 213 and can be retracted to be exposed in the first limiting groove 211, the first plug rod 12 is provided with a clamping portion 122, when the first plug rod 12 is inserted into the first limiting groove 211, the clamping portion 122 is used to cooperate with the elastic seat 22 to clamp the first locking member 10 and the second locking member 20 to lock each other, so as to connect the first subsection 200 and the second subsection 300.

[0031] Specifically, the first locking member 10 can be fixed to the first section 200 of the jewelry by welding, and the second locking member 20 can also be fixed to the second section 300 of the jewelry by welding. In some customized jewelry or series products, the first locking member 10 and the second locking member 20 can also be integrally formed with the first section 200 and the second section 300 when they are formed, so that different styles of jewelry modules can achieve stable and irreversible mutual locking as long as they have matching first locking members 10 and second locking members 20. When the first locking member 10 and the second locking member 20 are aligned with each other, the first insertion rod 12 is inserted into the first limiting groove 211, and the position of the first insertion rod 12 is limited by the first limiting groove 211. In the process of the first insertion rod 12 entering the first limiting groove 211, the first insertion rod 12 passes through the elastic seat 22 exposed in the first limiting groove 211. Due to the elastic effect of the elastic seat 22, the end of the first insertion rod 12 can squeeze and deform the elastic seat 22 when passing through the elastic seat 22, so that the elastic seat 22 is compressed and accommodated in the third limiting groove 213, thereby preventing the first insertion rod 12 from continuing to penetrate into the first limiting groove 211. When the clamping portion 122 of the first insertion rod 12 is aligned with the elastic seat 22, the first insertion rod 12 releases the squeezing of the elastic seat 22, so that the elastic seat 22 returns to its initial state and extends from the third limiting groove 213 to the first limiting groove 211, and engages with the clamping portion 122. At this point, the first locking member 10 and the second locking member 20 complete the preliminary connection and locking.

[0032] When the first inserting rod 12 is inserted into the first limiting groove 211 , the second inserting rod 13 enters into the second limiting groove 212 and is limited in position by the second limiting groove 212 . First, the first plug rod 12 and the second plug rod 13 are fixed by the first limiting groove 211 and the second limiting groove 212 at the same time, so that the first plug rod 12 and the second plug rod 13 can restrain each other, providing double stability for the first locking member 10 and the second locking member 20. Secondly, since the groove depth direction 21X of the second limiting groove 212 is perpendicular to the groove depth direction 21Y of the third limiting groove 213, and due to the limiting effect of the third limiting groove 213 on the elastic seat 22, the elastic seat 22 can only be deformed along the groove depth direction 21Y of the third limiting groove 213, so that after the second plug rod 13 is limited by the third limiting groove 213, the first locking member 10 no longer has the flexibility and space to move in the direction perpendicular to the second plug rod 13, which can prevent the elastic seat 22 from deforming after the first plug rod 12 is stably inserted in the first limiting groove 211, thereby causing the first locking member 10 and the second locking member 20 to loosen.

[0033] Such a jewelry lock 100 can stably connect the first section 200 and the second section 300 of the modular jewelry, and ensure that it does not loosen during long-term wearing. Especially when used in highly ductile materials such as gold, the second insertion rod 13 can not only prevent the deformation of the elastic seat 22, but also resist the deformation of soft materials at any part along the groove depth direction 21Y of the third limiting groove 213, thereby ensuring the clamping stability of the first insertion rod 12 and the elastic seat 22.

[0034] In this embodiment, the first insertion rod 12 includes a connecting portion 121, a clamping portion 122 and a limiting portion 123 in the axial direction, the connecting portion 121 is connected to the first branch 200, and the diameter width of at least one side of the limiting portion 123 close to the clamping portion 122 is greater than the diameter width of the clamping portion 122.

[0035] Specifically, the diameter width described here does not limit the first plug rod 12 to a cylindrical shape. The connecting portion 121, the clamping portion 122 and the limiting portion 123 can be of any shape. The diameter width here is only used to indicate the maximum width of the connecting portion 121, the clamping portion 122 or the limiting portion 123 in the direction perpendicular to the axial direction of the first plug rod 12. The connecting portion 121 can have the same diameter width as the clamping portion 122, or it can be larger than the diameter width of the clamping portion 122. The clamping portion 122 can be formed by a groove between the connecting portion 121 and the limiting portion 123, so that the elastic seat 22 can be embedded in the grooved clamping portion 122 for clamping. Alternatively, the radial cross section of the limiting portion 123 can be larger than the radial cross section of the clamping portion 122 as a whole, and one end of the clamping portion 122 is connected to one end of the limiting portion 123, so that the clamping portion 122 and the limiting portion 123 are stepped. Since the limiting portion 123 has a larger diameter than the clamping portion 122 , the first inserting rod 12 cannot be withdrawn from the first limiting groove 211 , thereby forming an irreversible lock.

[0036] In this embodiment, the width of the limiting portion 123 gradually decreases from an end close to the locking portion 122 to an end away from the locking portion 122 .

[0037] Specifically, the limiting portion 123 may be conical, bullet-shaped, tongue-shaped, triangular plate-shaped, trapezoidal, arc-shaped, semicircular, hemispherical, heart-shaped, or simple deformations of the above shapes and combinations thereof. Since the main function of the limiting portion 123 is to limit the first insertion rod 12 from escaping from the first limiting groove 211, the diameter of at least one end of the limiting portion 123 close to the clamping member should be larger than the clamping portion 122 to ensure the firmness of the clamping. In order to make the limiting part 123 pass through the elastic seat 22 more smoothly, the limiting part 123 is designed to have a diameter gradually reduced from the end close to the clamping part 122 to the end away from the clamping part 122. The thinner end of the limiting part 123 first enters the gap between the elastic seat 22 and the inner wall of the first limiting groove 211, so that the elastic seat 22 gradually undergoes elastic deformation. During the process, the gap between the elastic seat 22 and the inner wall of the first limiting groove 211 gradually expands due to extrusion. The limiting part 123 has a guiding function due to the specificity of its shape. The gradually widening design of the limiting part 123 makes it easier for the component to pass through the elastic seat 22. Accordingly, the end of the limiting part 123 close to the clamping part 122 is always larger than the clamping part 122. When the first insertion rod 12 is to be pulled out of the first limiting groove 211, the limiting part 123 is blocked by the elastic seat 22 and cannot pass through the elastic seat 22 in the reverse direction.

[0038] In this embodiment, the limiting portion 123 is preferably in a bullet shape.

[0039] Specifically, the bullet-shaped shape has the characteristics of a smooth outer surface, and in the axial direction of the first insertion rod 12, the radial cross-sectional area of ​​the limit portion 123 increases gradually and evenly, so that the guiding effect of the limit portion 123 is more significant and it is easier to pass through the elastic seat 22. In addition, the shape of the bullet head is easy to process and not easy to deform, and is suitable as a component of jewelry with high ductility materials, fine structures, and other high design difficulties.

[0040] In this embodiment, the diameter of the connecting portion 121 is greater than the diameter of the clamping portion 122 .

[0041] Specifically, the connecting portion 121 can be a cube, a cuboid, a cylinder or a pancake, etc., and the diameter of the connecting portion 121 is larger than the diameter of the clamping portion 122, which makes the connection area between the first plugging rod 12 and the first base 11 larger, which is conducive to the stable fixation of the first plugging rod 12 and enhances the clamping stability of the clamping portion 122 and the elastic seat 22. At the same time, the first plugging rod 12 can be designed to be thinner and can match more delicate jewelry.

[0042] Please continue to refer to Figure 1-2In the present embodiment, the second plug rod 13 can be arranged parallel to, perpendicular to, or at an angle to the first plug rod 12. It is only necessary to keep the elastic deformation directions of the second plug rod 13 and the elastic seat 22 perpendicular to each other. Of course, in other embodiments, in order to avoid design difficulties, the groove depth direction 21Y of the second plug rod 13 and the third limiting groove 213 can also be appropriately set to other suitable angles.

[0043] Preferably, the second insertion rod 13 is arranged parallel to the first insertion rod 12 .

[0044] Specifically, when the second plug rod 13 is arranged in parallel with the first plug rod 12, the second plug rod 13 can be inserted into the second limit groove 212 simultaneously with the first plug rod 12 being inserted into the first limit groove 211, thereby reducing the difficulty of arranging and plugging the first limit groove 211, the second limit groove 212, the first plug rod 12 and the second plug rod 13, making the overall structure of the jewelry lock 100 simple and convenient for mass production, use and maintenance. Moreover, the second plug rod 13 and the first plug rod 12 are arranged in parallel, so that the two can be concentrated in the same spatial direction, thereby improving the structural regularity of the first locking member 10, reducing the sharp angles or protrusions on the structure, reducing the probability of wear, and avoiding unnecessary space occupation of the first locking member 10.

[0045] In this embodiment, the second insertion rod 13 can be arranged on the first base 11, or can be arranged on the first insertion rod 12. Figure 3 Preferably, one end of the second plug rod 13 is connected to the first base 11, and the other end extends in a direction parallel to the first plug rod 12, so that the first plug rod 12 and the second plug rod 13 are parallel to each other.

[0046] Specifically, the second plug rod 13 is connected to the base, which can make the fixation of the second plug rod 13 more stable, avoid the second plug rod 13 being limited by the stability of the first plug rod 12, and can disperse the connection and fixing force between the first locking member 10 and the second locking member 20 in the linear direction with the first plug rod 12, and avoid a single component being subjected to a large force and causing a bucket effect.

[0047] In this embodiment, the elastic seat 22 includes a first spring 221 and a first clamp 222. The first clamp 222 is connected to the second base 21 through the first spring 221. A clamping groove 222a is provided on the side of the first clamp 222 away from the first spring 221. The first clamp 222 is elastically deformed by the first spring 221 and is accommodated in the third limiting groove 213 to prevent the first insertion rod 12 from entering the first limiting groove 211. When the clamping portion 122 is aligned with the first clamp 222, the clamping portion 122 is embedded in the clamping groove 222a and clamped by the first clamp 222.

[0048] Specifically, the first clamp 222 is in a "U"-shaped structure, with a clamping groove 222a formed on one side of the opening, and a sealed side connected to the first spring 221. When the first spring 221 is in an initial state, it is located in the third limiting groove 213 and partially exposed in the first limiting groove 211, so as to push the first clamp 222 into the first limiting groove 211. When the first insertion rod 12 is inserted into the first limiting groove 211, one end of the first insertion rod 12 gradually enters the clamping groove 222a. At the same time, the first insertion rod 12 squeezes the first clamp 222 and pushes the first clamp 222 toward the third limiting groove 213, and the first spring 221 is compressed and accommodated in the third limiting groove 213 until the clamping portion 122 of the first insertion rod 12 is aligned with the first clamp 222. Due to the clamping cooperation between the clamping portion 122 and the elastic seat 22, the first clamp 222 pops out into the first limiting groove 211 and clamps with the clamping portion 122 to limit the position of the first insertion rod 12.

[0049] Furthermore, the elastic seat 22 also includes a guide rod, and the first spring 221 is sleeved on the outside of the guide rod. The guide rod is set along the groove depth direction 21Y of the third limiting groove 213, and is used to guide or limit the deformation direction of the first spring 221, so that the deformation of the first spring 221 is controllable, which is convenient for setting the second insertion rod 13 to limit the deformation of the first spring 221, thereby preventing the jewelry lock 100 from being unlocked due to the deformation of the first spring 221.

[0050] In this embodiment, the third limiting groove 213 is set to penetrate the first limiting groove 211 and the outside of the second base 21, and the elastic base 22 also includes a baffle 223. The first spring 221 is fixed on the baffle 233. The baffle 223 is used to block the end of the third limiting groove 213 away from the first limiting groove 211, so that the first spring 221 cannot be observed and contacted from the outside of the second base 21. When the first locking member 10 is inserted into the second base 21, the first spring 221 is inserted into the third limiting groove 213 along with the baffle 233, and the baffle 233 blocks one end of the third limiting groove 213 to isolate the first spring 221 from the outside of the second base 21.

[0051] In this embodiment, the first base 11 has a first step 111 and a second step 112, the cross-sectional area of ​​the first step 111 is smaller than the cross-sectional area of ​​the second step 112, the first plug rod 12 and the second plug rod 13 are both arranged on the first step 111, and a receiving groove 214 is opened on one side edge of the second base 21, the first limiting groove 211 and the second limiting groove 212 are both connected to the receiving groove 214, when the first locking member 10 and the second locking member 20 cooperate to lock, the first plug rod 12 and the second plug rod 13 successively or simultaneously enter the first limiting groove 211 and the second limiting groove 212, the receiving groove 214 is used to accommodate the first step 111, so that the first base 11 and the second base 21 are interlocked with each other, the connection tightness of the first locking member 10 and the second locking member 20 is enhanced, and the force of the first plug rod 12 and the second plug rod 13 is dispersed, the first step 111 and the second plug rod 13 jointly limit the elastic deformation of the elastic seat 22, and further improve the irreversible locking function of the jewelry lock 100. After the first step 111 is completely received in the receiving groove 214 , the second step 112 abuts against the outer surface of the first base 11 .

[0052] Furthermore, the first plug rod 12 may be longer than the second plug rod 13, or may be equal in length to the second plug rod 13. In order to save materials or to prevent the second plug rod 13 from being easily deformed due to being too long, it is preferred that the second plug rod 13 is shorter than the first plug rod 12. When the first plug rod 12 is equal in length to the second plug rod 13, the first plug rod 12 and the second plug rod 13 enter the first limiting groove 211 and the second limiting groove 212 at the same time; when the first plug rod 12 is longer than the second plug rod 13, the first plug rod 12 and the second plug rod 13 enter the first limiting groove 211 and the second limiting groove 212 in sequence.

[0053] The jewelry lock 100 provided by the utility model is configured to have a first plug rod 12 that is engaged with the elastic seat 22, and to have a second plug rod 13 that is perpendicular to the groove depth direction 21Y of the third limiting groove 213, so that the second plug rod 13 can limit the deformation of the elastic seat 22 in the third limiting groove 213, thereby preventing the elastic seat 22 from being compressed due to the high ductility of the jewelry material or the influence of force majeure, causing it to be accommodated in the third limiting groove 213, and avoiding the elastic seat 22 from being unable to block the first plug rod 12 from exiting the first limiting groove 211, so that the jewelry lock 100 cannot be unlocked after being locked, thereby improving the locking stability of the first locking member 10 and the second locking member 20. Since the second plug rod 13 has the function of resisting material deformation, the jewelry lock 100 can be adapted to materials with high ductility such as gold.

[0054] Second embodiment

[0055] Please refer to Figure 4Another aspect of the present invention is to provide a bracelet, comprising a first section 200, a connecting buckle 400, a second section 300 and the jewelry clasp 100 as described in the first embodiment, wherein the first section 200, the connecting buckle 400, the second section 300 and the jewelry clasp 100 are sequentially connected to form a closed ring structure.

[0056] Specifically, the first division 200 and the second division 300 can be arc-shaped, "]"-shaped, etc. The structure of the connecting buckle 400 is not exactly the same as that of the jewelry lock 100. The purpose is to avoid the two connection points of the first division 200 and the second division 300 of the bracelet being subjected to the same force and easy to unlock.

[0057] In other embodiments, the bracelet may further include a third subsection, a fourth subsection and several other parts, each of which may be connected via a connecting port and the jewelry lock 100 .

[0058] In this embodiment, the first section 200 is a tubular structure, and the second locking member 20 further includes an insert column 10b, one end of which is connected to the second base 21, and the other end is used to be inserted into the first section 200 to connect the second base 21 to the first section 200.

[0059] Specifically, the second sub-section 300 may have the same structure as the first sub-section 200 or may be different. The first sub-section 200 and the second sub-section 300 may be in the shape of a round tube, a square tube, etc., and the drawings take a round tube as an example. The tubular first sub-section 200 is conducive to the lightweight design of the jewelry, and reduces stress to prevent the jewelry from breaking during wearing.

[0060] In this embodiment, an embedding groove 10a is provided on the side of the second base 21 away from the accommodating groove 214, and the embedding groove 10a is used for the second division 300 to be plugged in, so that the first locking member 10 is plugged into the first division 200, the first locking member 10 is plugged into the second base 21, and the second division 300 is plugged into the second locking member 20, that is, the opposite ends of the first locking member 10 are plugged into the adjacent components, and the opposite ends of the second locking member 20 accept the insertion of the adjacent components, so that the first locking member 10 and the second locking member 20 are subjected to different force modes, thereby avoiding affecting the locking stability of the jewelry lock 100 when subjected to forces in the same direction.

[0064] Furthermore, the third insertion rod 412 includes a mushroom head 412a and a clamping portion 412b in the axial direction. The cross-sectional area of ​​the mushroom head 412a gradually decreases from one end close to the clamping portion 412b to the end away from the clamping portion 412b. The diameter of the widest part of the mushroom head 412a is greater than the diameter of the clamping portion 412b. The clamping portion 412b is used to connect the third base 411 and the mushroom head 412a and is clamped and connected by the second clamp 423. When the third insertion rod 412 enters the fourth limiting groove, the narrower part of the mushroom head 412a of the third insertion rod 412 The second end first enters the second clamp 423, and as the mushroom head 412a becomes wider, it squeezes the second clamp 423, and the second spring 422 is compressed accordingly, so that the second clamp 423 avoids the third insertion rod 412 and continues to extend into the fourth limiting groove until the clamping portion 412b is aligned with the second clamp 423, and the mushroom head 412a no longer squeezes the second clamp 423, so that the second spring 422 can be reset, and the second clamp 423 pops out and clamps and fixes the clamping portion 412b, so that the third locking member 410 and the fourth locking member 420 are locked.

[0065] Furthermore, the first section 200 and the second section 300 are both tubular, and the fourth locking member 420 further includes a fifth insertion rod 424 , which is used for being plugged into the first section 200 .

[0066] In this embodiment, after the first locking member 10 , the second locking member 20 , the third locking member 410 and the fourth locking member 420 are connected to the first sub-portion 200 or the second sub-portion 300 , welding is performed at the connection ports.
