Description

Technical Field

[0001] The utility model relates to the field of jewelry connection, in particular to a capsule-shaped jewelry lock buckle used for connecting necklaces or bracelets. Background Art

[0002] The main function of jewelry is decoration. They are usually used to beautify personal appearance, decorate homes, and beautify public environments. There are many types of jewelry, mainly including necklaces, bracelets, etc. The general function of jewelry buckles is to ensure that jewelry such as necklaces and bracelets will not fall off the wearer after being worn.

[0003] At present, most bracelets or necklaces are connected by circular buckles, and some are connected by "M" buckles. Among them, the lock form of the "M" buckle will easily break at the connection due to improper operation or long-term repeated manipulation during actual use, which not only has a low service life, but also easily causes the loss of jewelry. As for the jewelry connection method in the form of circular buckles, its specific structural forms are diverse. For example: the announcement number is: CN2530498, and the patent name is a utility model patent for necklace lock, which discloses a male buckle, a female buckle and a spring; a convex column is convexly provided at the inner end of the male buckle, and a √-shaped card groove is concavely provided on the front surface side of the convex column; the √-shaped card groove is composed of an inclined introduction groove and an inclined stop groove bent and extended from the rear end of the inclined introduction groove; the inner end of the female buckle is a hollow sleeve corresponding to the convex column at the inner end of the male buckle and sleeved, and the inner wall of the front end of the sleeve is convexly provided with a card particle that slides and stops in the √-shaped card groove of the male buckle; the spring assembly is arranged in the inner end sleeve of the female buckle and is stuck on the card particle. Although this structure can achieve effective connection between accessories, the accessories are relatively small and cannot be pressed or are inconvenient to press during insertion and removal, resulting in inconvenience in removal. Moreover, when using a ring-connected lock, the two ends of the ring connection are easily pulled apart after being stressed, and it is difficult to restore the original state. Repeated pulling is very easy to fatigue, resulting in falling off, reducing the stability of the bracelet.

[0004] In summary, the existing jewelry locks are prone to causing the jewelry to fall off, thereby reducing the stability of the bracelet. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the existing jewelry lock buckle is easy to cause the jewelry to fall off and reduce the stability of the bracelet. A capsule-shaped jewelry lock buckle is provided.

[0010] Furthermore, the number of elastic locking parts is 2, and each elastic locking part includes a first clip, a second clip, a first limiting boss, a second limiting boss and a connecting spring. The first limiting boss is installed at one end of the first clip to form a first clip, and the other end of the first clip is spherical, and the outer diameter of the first clip is smaller than the outer diameter of the first limiting boss. The second limiting boss is installed at one end of the second clip to form a second clip, and the other end of the second clip is spherical, and the outer diameter of the second clip is smaller than the outer diameter of the second limiting boss. The first clip and the second clip are arranged in a mirror image, and the first clip and the second clip are connected by a connecting spring.

[0011] Furthermore, upper anti-slip stripes and lower anti-slip stripes are respectively arranged on the outer side walls of the connection between the upper shell and the lower shell.

[0015] Preferably, the overall height of the upper housing is smaller than the overall height of the lower housing.

[0016] Compared with the prior art, the utility model has the following effects:

[0017] 1. The lock buckle of the utility model adopts an elastic screwing design, which can tightly fix the two ends of the jewelry after insertion. Under the limit of the ring, the buckle body 12 and the elastic locking piece are not easy to loosen due to accidental touch, which effectively prevents the jewelry from accidentally falling off during wearing.

[0018] 2. When the utility model is actually used for removal, there is no need to press, just use the belly of your finger to twist it into the groove and separate the upper shell 6 and the lower shell 9. The maximum rotation angle is 90 degrees, which is convenient for removal. When locking is required, just plug the upper shell 6 and the lower shell 9 together. When plugging, the elastic locking piece touches the internal protrusion 14 and then compresses, enters the lower shell 9, and quickly completes the plugging. This avoids the problem that the existing lock buckle also needs to be pressed to lock, and it is even easy to hurt the nail bed when pressing.

[0019] 3. During wearing, the lock buckle of the utility model is not subjected to the force of rotation but only to the tensile force of the bracelet or necklace. Therefore, it is more secure to wear and not easy to get loose. BRIEF DESCRIPTION OF THE DRAWINGS

The ring 18 is embedded in the upper inner wall of the lower shell 9, the internal protrusion 14 is installed on the upper end face of the ring 18, a groove 15 is provided on the ring 18, the elastic locking member is horizontally inserted into the buckle body 12, and the elastic member 20 is installed at the bottom of the lower shell 9. When the elastic locking member is inserted into the lower shell 9 along with the buckle body 12, the elastic locking member is compressed under the action of the internal protrusion 14, and the elastic locking member is released after passing through the ring 18 to achieve locking. When the buckle body 12 is rotated and lifted upward, the elastic locking member is pulled out along the groove, the buckle body 12 is embedded in the upper shell 6, and the upper shell 6 is buckled on the lower shell 9 to form a capsule-shaped lock.

[0030] Specific implementation method 2: Combination Figure 1 To explain this embodiment, the elastic member 20 of this embodiment is a hemispherical sponge. With such a configuration, when the buckle body 12 is inserted downward into the lower housing 9, the buckle body 12 contacts and compresses the elastic member 20. At this time, the elastic member 20 is compressed and stores energy for the rapid ejection of the buckle body 12. When unlocking is required, the buckle body 12 is rotated so that the elastic locking member on the buckle body 12 is rapidly ejected along the groove under the energy storage force of the elastic member 20. The other components and connection relationships are the same as those of the first embodiment.

[0031] Specific implementation method three: Combination Figure 1 and Figure 2 To explain this embodiment, the buckle body 12 of this embodiment is a hollow cylinder, the elastic locking piece is horizontally arranged on the buckle body 12, and the two ends of the elastic locking piece can be extended out of the side wall of the buckle body 12. Such a configuration facilitates the buckle body 12 to be inserted into the lower housing 9, the elastic locking piece is in a released state, and locking is achieved under the limiting effect of the ring 18. Other components and connection relationships are the same as those of the first or second specific embodiments.

[0032] Specific implementation method four: Combination Figure 1 , Figure 5 and Figure 8 In this embodiment, the number of the internal protrusions 14 is two, and the longitudinal cross-section of the internal protrusions 14 is triangular. This arrangement facilitates contact with the elastic locking member and guides the elastic locking member to achieve compression, thereby smoothly achieving the insertion of the buckle body 12. The other components and connection relationships are the same as any one of the specific embodiments 1 to 3.

[0033] Specific implementation method five: Combination Figure 3To illustrate this embodiment, the number of elastic locking parts in this embodiment is 2, and each elastic locking part includes a first clip 1, a second clip 5, a first limiting boss 2, a second limiting boss 4 and a connecting spring 3. The first limiting boss 2 is installed at one end of the first clip 1 to form a first clip, and the other end of the first clip 1 is spherical, and the outer diameter of the first clip 1 is smaller than the outer diameter of the first limiting boss 2. The second limiting boss 4 is installed at one end of the second clip 5 to form a second clip, and the other end of the second clip 5 is spherical, and the outer diameter of the second clip 5 is smaller than the outer diameter of the second limiting boss 4. The first clip and the second clip are arranged in a mirror image, and the first clip and the second clip are connected by a connecting spring 3.

[0034] In this way, the first limiting boss 2 and the second limiting boss 4 are located in the buckle body 12 and play a limiting role, so that the first limiting boss 2 and the second limiting boss 4 are stuck under the elastic force of the connecting spring 3 and are not easy to slide out when subjected to force; when the first buckle 1 and the second buckle 5 are compressed when subjected to external force, the length of the entire elastic locking member extending to the outside of the buckle body 12 is guaranteed. Other components and connection relationships are the same as any one of the specific embodiments one to four.

[0035] Specific implementation method six: Combination Figure 1 , Figure 2 and Figure 4 To explain this embodiment, the outer side walls of the upper shell 6 and the lower shell 9 of this embodiment are respectively provided with upper anti-slip stripes 7 and lower anti-slip stripes 8. Such a configuration facilitates quick unlocking by twisting, and avoids the problem of inconvenience in unlocking caused by slippery hands of the user. The other components and connection relationships are the same as any one of the specific embodiments 1 to 5.

[0036] Specific implementation method seven: Combination Figure 1 , Figure 2 and Figure 4 To explain this embodiment, the bottom of the lower housing 9 of this embodiment is a hemispherical body 10, and the elastic member 20 is embedded in the hemispherical body 10. This arrangement is convenient for forming a capsule shape, with a compact structure and no space occupied, and the hemispherical body provides an installation space for the energy-storing elastic member 20. Other components and connection relationships are the same as any one of the specific embodiments 1 to 6.

[0037] Specific implementation method eight: Combination Figure 7 To illustrate this embodiment, this embodiment further includes a first slide groove 16 and a second slide groove 17 , which are symmetrically installed in the lower housing 9 , and the first slide groove 16 and the second slide groove 17 are installed on the groove 15 on the ring 18 .

[0038] Such arrangement facilitates providing compression force for the elastic locking member, so that it can be ejected smoothly along the groove. Other components and connection relationships are the same as any one of the specific embodiments 1 to 7.

[0039] Specific implementation method nine: Combination Figure 7 To explain this embodiment, the first slide groove 16 and the second slide groove 17 of this embodiment have the same structure. The first slide groove 16 is a long strip slide groove. In the horizontal direction, one side of the first slide groove 16 is a circular arc convex transition part, and the other side is a concave slide groove part. The circular arc convex transition part and the concave slide groove part are made into one piece. With such a configuration, the circular arc convex transition part is convenient for providing guidance and transition when the elastic locking member rotates. At this time, the connecting spring 3 is compressed. When it rotates to the concave slide groove part, the connecting spring 3 releases the elastic force and bounces upward along the concave slide groove part to achieve unlocking. The other components and connection relationships are the same as any one of the specific embodiments one to eight.

[0040] Specific implementation method ten: Combination Figure 1 , Figure 2 and Figure 4 To explain this embodiment, in this embodiment, the overall height of the upper housing 6 is smaller than the overall height of the lower housing 9 .

[0041] This arrangement makes it easy for the user to identify that the upper housing 6 needs to be rotated, which is convenient and quick to operate and has high recognition. It can also save space. The other components and connection relationships are the same as any one of the specific embodiments 1 to 9.

[0042] Combination Figures 1 to 8 Explain the working principle of the utility model:

[0043] The utility model is arranged horizontally. At this time, the upper shell 6 is moved laterally to move the buckle body 12 toward the inside of the lower shell 9. When the buckle body 12 contacts the internal protrusion 14 on the inner side of the lower shell 9, the outer surfaces of both ends of the elastic locking member are squeezed by external force, and the connecting spring 3 begins to compress.

[0044] The buckle body 12 continues to move downward, and when the elastic locking piece shrinks inward and smoothly passes through the internal protrusion 14, the connecting spring 3 immediately recovers its original length. At this time, the elastic locking piece cannot be pulled outward by external force.

[0045] When both elastic locking members pass through the inner protrusion 14, the upper shell 6 and the lower shell 9 are completely in contact. Since the ring 18 has a blocking effect on the buckle body 12, the buckle structure is fixed and does not move laterally, thereby improving the stability of the structure.

[0046] When the upper housing 6 and the lower housing 9 are rotated clockwise, the elastic locking member moves toward the first sliding groove 16 and the second sliding groove 17 along the arc convex transition portion.

[0047] The first slide groove 16 and the second slide groove 17 are tightly connected to the inner surface of the lower shell 9, and the surface of the lower shell 9 is provided with upper anti-skid stripes 7 and lower anti-skid stripes 8, which are easy to rotate and convenient to operate. The rotation method is not easy to trigger in daily life, reducing the possibility of the ornaments slipping off.

[0048] The sponge is elastically deformed because the bottom end of the buckle body 12 squeezes the bottom elastic member 20. Since the bottom of the lower shell 9 is a hemispherical hollow structure, the elastic sponge is fixed to the bottom end of the shell.

[0049] After the rotation, the spring structure is compressed and contracts inward again, the elastic locking piece is separated from the arc convex transition portion, and smoothly connects with the concave slide groove portion, the elastic sponge returns to its original state, and the buckle body 12 quickly pops out along the slide groove direction to complete the unlocking.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
