The present invention relates to a jewelry clasp, and more particularly to a jewelry clasp device or mechanism connecting and securing two ends of a jewelry chain.
At present, most jewelry chains (including hand chains and necklaces) in the market comprise a chain, a male connector and a female connector. The connections between one end of the chain and the male connector and between another end of the chain and the female connector are fixed, securing the male connector and the female connector together so that the chain forms a closed loop. This type of jewelry chain mainly has the following disadvantages: First, the two ends of the chain are fixedly connected with the male connector component and the female connector component respectively, and the connection is completed by the manufacturers before product release; consumers cannot disassemble freely; also, consumers cannot change the color of the clasp device or the style of the chain according to their personal tastes and outfits matching needs in order to develop personalized style trends. Second, the clasp structure of the male connector and the female connector is completely exposed, so that it is easily chafed against other objects and detached when user is putting on the jewelry chain, resulting in unsecure locking and easy detachment. Third, as the clasp structure of the male connector and the female connector is completely exposed, the appearance of the jewelry chain is largely affected. Fourth, the male connector and the female connector only have one type of color and shape, and can only follow the original color of the jewelry chain; consumers can only accept a jewelry chain in the color predetermined by the manufacturers before product release; consumers cannot change the colour and shape of the clasp according to personal tastes and outfits matching needs to develop personalized style trends. In view of the aforesaid disadvantages now present in the prior art, it is essential to redevelop and redesign the connective structure of this part.
An object of the present invention is to provide a jewelry chain clasp which has the advantages of secure locking, secure connection, being impossible to detach accidentally, convenient to lock, convenient to disassemble and assemble, simple and aesthetic in appearance, convenient for consumers to freely mix and match, simple in structure, and highly reliable and durable.
To achieve this, the present invention adopts the following technical proposal: A jewelry clasp comprising a male connector, a female connector, a locking sleeve, chain connectors and locking cylinders, wherein the chain connectors are connected to outer end surfaces of the male connector and the female connector. The locking cylinders are sleeved onto outer ends of the male connector and the female connector. Positioning locking means which allow the chain connectors, the male connector and the female connector to be reliably connected together are provided between the locking cylinders and the chain connectors. The female connector is sleeved into one end of the locking sleeve, and a locking means is provided between the female connector and the locking sleeve. The male connector is sleeved into another end of the locking sleeve; an inner end of the male connector is coupled with an inner end of the female connector; a locking means is provided between the male connector and the locking sleeve. Rotation of the locking sleeve once enables the locking means at two ends of the locking sleeve to reliably and securely lock and couple the male connector and the female connector together.
Furthermore, the outer end surfaces of male connector and the female connector are each provided with a coupling cavity, and the chain connectors are sleeved into the coupling cavities.
Furthermore, the positioning locking means for reliably coupling the chain connectors, the male connector and the female connector may have two embodiments, namely: First, the chain connectors each has an outer appearance of a specific shape which is identical to a shape of each of the coupling cavities; an outer end surface of each of the locking cylinders is provided with a positioning opening for passage of the chain connector. An outer surface of each of the locking cylinders is further provided with an elongated hole, and the pins enter from the elongated holes to be secured on the male connector and the female connector respectively to enable the locking cylinders to be sleeved onto the male connector and the female connector respectively. Rotation of the locking cylinders once causes the chain connectors and the positioning openings to offset with each other to position and lock the chain connectors in the coupling cavities. Second, the chain connectors each has an outer appearance of a specific shape which is identical to a shape of each of the coupling cavities; a shaft is provided on an outer surface of each of the chain connectors; the locking cylinders are each provided with a locking slot and an elongated hole; the coupling cavities of the male connector and the female connector each has a groove at a cavity wall thereof; the pins enter from the elongated holes to be secured on the male connector and the female connector respectively to enable the locking cylinders to be sleeved onto the male connector and the female connector respectively; the shafts embed into the grooves and the locking slots respectively; rotation of the locking cylinders once causes locking of the shafts and the locking slots to position and lock the chain connectors into the coupling cavities.
Furthermore, the locking means for reliably coupling the locking sleeve, the male connector and the female connector may have two embodiments, namely: First, the locking sleeve is provided with a locking slot in an inner wall at each of two ends of the locking sleeve; the pins secured at the male connector and the female connector respectively have a length exceeding thickness of the locking cylinders; the male connector is provided with a coupling portion; the female connector is provided with a coupling portion receiving cavity; the coupling portion of the male connector and the coupling portion receiving cavity of the female connector are coupled together; top ends of the pins are embedded in the locking slots; rotation of the locking sleeve once enables the pins and the locking slots to lock with each other to reliably and securely lock and couple the male connector and the female connector together. Second, the locking sleeve is provided with a locking slot in an inner wall at one end of the locking sleeve, an inner wall at another end of the locking sleeve is provided with a positioning flange; the male connector is provided with a coupling portion, and a positioning annular groove is provided on the coupling portion; the female connector is provided with a coupling portion receiving cavity; the pin secured at the female connector has a length exceeding thickness of the locking cylinder; the coupling portion of the male connector passes through the positioning flange to couple with the coupling portion receiving cavity of the female connector; the positioning annular groove on the coupling portion embeds with the positioning flange; a top end of the pin at the female connector is embedded in the locking slot; rotation of the locking sleeve once enables the pin and the locking slot to lock with each other and the positioning annular groove and the positioning flange to be embedded in offset, thereby reliably and securely locking and coupling the male connector and the female connector together.
The present invention has the following beneficial effects: (1) when in use, the chain connectors are responsible for connecting the chain of the jewelry chain, the positioning locking means between the locking cylinders and the male connector and the female connector couples the male connector and the female connector together, and the locking sleeve and the locking means couple the male connector and the female connector together. The entire assembly details of the present invention are concealed inside the locking sleeve, and thus the aesthetics and neat appearance of the jewelry chain would not be affected. Only the outer appearance of the locking sleeve can be seen from outside. It is therefore neat, aesthetically pleasing and delicate. (2) The locking cylinders securely and safely lock the chain connectors and the male connector and the female connector, and the locking sleeve also securely and safely locks the male connector and the female connector, so that the jewelry chain would not detach accidentally when worn, and would not detach itself due to accidental contact of the internal locking structure. (3) The entire structure of the present invention does not require screws or tools for disassembling and assembling, so that when consumers use the jewelry chain, they can easily change the styles of the jewelry chain or switch to locking sleeves of different styles according to styling and adornment needs. It helps consumers to develop personalized style trends. Besides, this design also facilitates jewelry manufacturers to provide locking sleeves of different colors and styles for matching with each jewelry chain products, so as to facilitate consumers to switch between locking sleeves of different colors according to personal tastes and outfits matching needs, thus fulfilling consumers' needs for styling and adornment.
