[0002] Jewelry connecting lock is a kind of connecting lock used for wearing jewelry, usually used in necklaces, bracelets, and bracelets;

[0003] Most existing jewelry connections are made using lobster clasps, M clasps, etc.

[0004] Because it is jewelry, the lobster clasp is small in size and difficult to wear and remove, especially when worn on a bracelet, which can only be operated with one hand, so it is less convenient. The M clasp connection is not convenient and is easy to fall off;

[0005] Some existing technologies also use snap-fit ​​connections, but screws, riveting, and other processes are used during assembly. Screw fixation is located on the outside, which affects the appearance and easily leaves dirt. Although riveting fixation can avoid the problems of screw fixation, it is difficult to remove once assembled. Even if removed, the riveted part cannot be reused, which is not conducive to the replacement and maintenance of individual components.

[0006] In order to solve the above problems, this application proposes a bracelet connection mechanism. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0023] See also Figure 1-4 The utility model provides the following technical solutions: a bracelet connecting mechanism, including a connecting base 1, a movable groove 11 is provided on the connecting base 1, a docking sleeve 2 is plugged in and engaged with the side of the connecting base 1, a first slot 23 is provided in the docking sleeve 2, a pressing block 4 is slidably provided in the movable groove 11, a limiting plate 41 that is engaged with the first slot 23 is fixed at the lower end of the pressing block 4, a conical spring 3 is provided in the movable groove 11 for stably engaging the docking sleeve 2 and the limiting plate 41, and also includes a first joint 5 that is plugged in and engaged with the docking sleeve 2, and a second slot 51 is provided on the first joint 5 that is engaged with the limiting plate 41. The connecting base 1 in this embodiment can be set to a square, rectangle, circle, ellipse, etc. according to actual needs.

[0024] Specifically, the docking sleeve 2 is vertically distributed to the movable groove 11, and a docking hole 21 for plugging with the first joint 5 is opened through the inside of the docking sleeve 2. In this embodiment, the movable groove 11 is vertically distributed to the docking sleeve 2. When the first joint 5 is inserted into the docking sleeve 2, it is locked by the limit plate 41 vertically distributed therewith, which has the advantages of flexible structure and high reliability.

[0025] Specifically, a symmetrical anti-rotation groove 22 is provided at one end of the docking sleeve 2 that cooperates with the limiting plate 41, and a limiting opening 42 that is plugged into the anti-rotation groove 22 is provided through the limiting plate 41; the first card slot 23 is located at the end of the anti-rotation groove 22, and the end of the anti-rotation groove 22 contacts a side wall of the limiting plate 41. In this embodiment, the cooperation between the anti-rotation groove 22 and the limiting opening 42, as well as the cooperation between the end of the anti-rotation groove 22 and the limiting plate 41, ensure the reliability of the cooperation between the limiting plate 41 and the first card slot 23.

[0026] Specifically, the first card slot 23 is engaged with the limit plate 41, and a movable space is also formed in the first card slot 23 when engaged with the limit plate 41. In this embodiment, the movable engagement between the first card slot 23 and the limit plate 41 can not only ensure the engagement stability of the two, but also the first card slot 23 provides the condition for the limit plate 41 to enter the docking hole 21, and then can be engaged with the second card slot 51 inserted into the docking sleeve 2, realizing double engagement and high structural coordination.

[0027] Specifically, the limit plate 41 is engaged with the first slot 23 and the second slot 51 at the same time through the conical spring 3. The engagement and disengagement range of the limit plate 41 and the second slot 51 is within the movable range of the engagement of the limit plate 41 and the first slot 23. In this embodiment, through the stroke setting, the limit plate 41 can be stably engaged with the first slot 23, and can also be flexibly engaged with or disengaged from the second slot 51, thereby making the entire connector free of screws, rivets, etc.

[0028] Specifically, the first joint 5 and the second joint 6 are integrally connected to a connecting head 7 at one end away from the connecting seat 1. The external thread of the connecting head 7 is connected to a connecting cap 8. The external part of the connecting head 7 is also fitted with a rubber ring 9 that cooperates with the connecting cap 8. In this embodiment, the cooperation between the connecting head 7 and the connecting cap 8 facilitates the connection with the bracelet, and the rubber ring 9 strengthens the friction between the threads, making the bracelet and the connecting structure more reliably connected.

[0029] The working principle and usage process of the present invention are as follows: the various components are processed and formed, the second joint 6 is directly fixed to the connecting seat 1 by pressing, the conical spring 3 is installed in the bottom of the movable groove 11, the pressing block 4 is installed in the movable groove 11 and resists against the conical spring 3, the pressing block 4 is pressed to the bottom, the conical spring 3 is deeply compressed, and the docking sleeve 2 is inserted from the side of the connecting seat 1, and the anti-rotation groove 22 enters along the side wall of the limit opening 42 until the docking sleeve 2 is inserted into place. At this time, the pressing block 4 is released, and the limit plate 41 is clamped into the first clamping groove 23 under the action of the conical spring 3. At this time, the docking sleeve 2 is installed in the connecting seat 1 under the action of the conical spring 3 and the pressing block 4. The two ends of the bracelet pass through the connecting caps 8 at both ends and are fixed, the rubber ring 9 is fitted on the outside of the connecting head 7, and the connecting cap 8 is spirally connected to the connecting head 7. At this time, the entire jewelry assembly is completed;

[0030] Lock connection: Insert the first connector 5 into the docking hole 21. The chamfered front end of the first connector 5 contacts the bottom of the limit opening 42 and pushes it downward. The conical spring 3 is compressed. Under this compression, the limit plate 41 and the first slot 23 are still in the locked state until the second slot 51 is docked with the first slot 23 and the limit plate 41. Then, the limit plate 41 is engaged with the second slot 51 under the action of the conical spring 3. At this time, the jewelry is completely closed.

[0031] Lock disengagement: Press the pressing block 4 toward the inside of the connecting seat 1 to drive the limit plate 41 to move downward. Since the area of ​​the pressing block 4 is much smaller than the area of ​​the fingertip, it is not pressed down excessively. Under this pressure, the limit plate 41 disengages from the second slot 51 but still ensures engagement with the first slot 23, and the first connector 5 is successfully disconnected from the connecting seat 1.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
