DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model. EMBODIMENT

[0025] Please refer to Figures 1-6 The utility model provides the following technical scheme: a jewelry convenient to replace chain, jewelry includes shell 1 and chain 3, and the connecting end of chain 3 is fixed with U-shaped groove 11 with shell 1, and shell 1 is inlaid with the ornament 8 that can be replaced, and the ornament 8 can be diamond, ornament etc., and is detachable by thread, magnetic attraction etc. and is cooperated in shell 1;The ornament 8 can also be a lens with text engraved inside, and the lens can realize the projection of text after irradiation;The ornament 8 can also be a storage box that can be displayed outside, and small articles with commemorative significance, personal significance can be placed in the box;U-shaped groove 11 that cooperates with connecting pin 31 is set up on shell 1, and sliding cover 2 is slidably arranged at the opening of U-shaped groove 11 on shell 1, and clamping pin 5 for positioning sliding cover 2 is arranged in shell 1 by first spring 4, and release button 7 for locking sliding cover 2 and chain 3 on shell 1 is arranged in sliding cover 2 by second spring 6.

[0026] Specifically, the slide 12 for the sliding of the sliding cover 2 is set up on the shell 1, and symmetrical sliding grooves 121 are set up on both sides of the slide 12, and both ends of the sliding grooves 121 are open, and the clamping strips 21 are formed on both sides of the sliding cover 2 and slide in the sliding grooves 121, and in the embodiment, the open ends of the sliding grooves 121 facilitate the assembly and disassembly of the sliding cover 2 and the shell 1.

[0027] Specifically, the limiting groove 13 is further set up on one side of the slide 12 close to the U-shaped groove 11, and the limiting block 22 is integrally formed on one side of the sliding cover 2 and slides in the limiting groove 13, and in the embodiment, the limiting block 22 covers the opening of the U-shaped groove 11 and slides in the limiting groove 13, which can also limit the effect, avoiding the sliding cover 2 from being separated from the shell 1 due to excessive force.

[0028] Specifically, the bottom of the sliding cover 2 is provided with a slot 23 that contacts the locking pin 5 at the end away from the limiting block 22, and two recesses are formed in the slot 23. In this embodiment, one of the recesses of the slot 23 is used for positioning when the limiting block 22 covers the opening of the housing 1 to ensure the reliability of the connection, and the other recess is used for positioning when the limiting block 22 and the U-shaped groove 11 are misaligned, so as to facilitate the disengagement or docking of the connecting pin 31 and the U-shaped groove 11.

[0029] Specifically, a locking groove 122 is provided on the slide groove 121, and a locking pin 71 is provided on the release button 7, which engages with the locking groove 122 through the second spring 6. The thickness of the locking pin 71 is the same as that of the locking strip 21. When the limiting block 22 is located at the opening of the U-shaped groove 11, the locking pin 71 engages with the locking groove 122. In this embodiment, after the release button 7 is pressed down, the locking pin 71 can be completely flush with the locking strip 21. At this time, it disengages from the locking groove 122 and can slide in the slide groove 121. The thickness of the locking groove 122 is less than that of the locking pin 71. Therefore, even when the locking pin 71 engages with the locking groove 122, it is still partially located in the locking strip 21, thereby ensuring reliable locking.

[0030] Specifically, the sliding cover 2 has a connecting groove 25 inside to accommodate the second spring 6 and the release button 7. The upper end of the release button 7 passes through the sliding cover 2. The sliding cover 2 has a toggle rib 24 that is higher than the release button 7 on the outside. The toggle rib protrudes from the housing 1. In this embodiment, the toggle rib 24 is higher than the release button 7 to avoid or reduce the possibility of accidental touch. Even if the release button 7 is accidentally pressed, the locking pin 5 and the locking groove 23 need a certain force to disengage under the action of the first spring 4. Moreover, the directions of the forces required by the two are different, thereby achieving a double locking effect. The method of combining pressing and pushing also ensures the convenience of disassembly and assembly.

[0031] Specifically, the connection between the connecting pin 31 and the U-shaped groove 11 is provided with a mating T-shape. In this embodiment, the mating of the T-shape facilitates the radial docking between the connecting pin 31 and the U-shaped groove 11, and at the same time, it can form a stable connection in the axial direction. The radial opening of the U-shaped groove 11 is blocked by the limiting block 22, thereby locking the connecting pin 31 and the housing 1 after they are connected.

[0032] The working principle and usage process of this utility model: The completed jewelry assembly is as follows: Figures 1-3 As shown, at this time, the sliding cover 2 blocks the connecting pin 31, and the locking pin 71 is locked in the locking groove 122;

[0033] Dismounting of the chain 3 and the shell 1: after pressing the release button 7, the locking pin 71 is disengaged from the inside of the locking groove 122, at this time the second spring 6 is followed by compression, then push the sliding cover 2, at this time the first spring 4 will be compressed, the locking pin 5 is moved from one side to the other side of the clamping groove 23, the limiting block 22 is disengaged from the side opening of the U-shaped groove 11, that is, the connecting pin 31 can be smoothly taken out from the side opening of the U-shaped groove 11, the connecting pin 31 on the other side is also operated according to the above steps, of course, the two connecting pins 31 can also be removed at the same time; replace the required chain 3, place the connecting pin 31 in the U-shaped groove 11, at this time it is not necessary to press the release button 7, slide the sliding cover 2 in reverse direction, move the locking pin 5 to the other end of the clamping groove 23, the limiting block 22 blocks the opening of the U-shaped groove 11, the connecting pin 31 is locked, at the same time the locking pin 71 corresponds to the locking groove 122 and is clamped and locked under the action of the second spring 6.

[0034] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for the skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the scope of protection of the present application.
