[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example

[0021] like Figure 1 - Figure 4 As shown, a keychain with a magnetic snap-on pendant includes a keychain body 1 with a key ring 2 rotatably connected to its bottom end. A decorative pendant is suspended on the key ring 2. The decorative pendant decorates the keychain structure and greatly improves the overall aesthetics of the keychain.

[0022] The decorative pendant includes two symmetrically arranged side plates 3, with an intermediate interlayer 4 ultrasonically welded between the two side plates 3. A guide and limiting structure is provided on one side plate 3 near the intermediate interlayer 4. The guide and limiting structure includes two parallel guide grooves 5 opened on the inner wall of one side plate 3. A first magnetic block 6 is embedded in the inner wall of the top of each of the two guide grooves 5. The guide grooves 5 are used for guiding and limiting, and the first magnetic blocks 6 are used for adsorption and fixation by magnetic force.

[0023] The intermediate interlayer 4 forms a receiving cavity 7. Two spring positioning grooves 8 are opened on the bottom wall of the receiving cavity 7. Two vertically arranged first springs 9 are fixedly connected to the bottom wall of the receiving cavity 7. The bottom end of the first spring 9 is fixed to the bottom wall of the receiving cavity 7 through the spring positioning grooves 8 to improve the stability of the installation of the bottom end of the first spring 9 and the bottom wall of the receiving cavity 7.

[0024] An ejector 10 is slidably disposed in the receiving cavity 7 above the first spring 9. A second magnetic block 11 is fixedly installed in the middle section of the ejector 10 and is aligned with the guide limiting structure. The end of the second magnetic block 11 close to the first magnetic block 6 has opposite magnetism to the first magnetic block 6. When the ejector 10 slides up the guide groove 5 to the point where the second magnetic block 11 and the first magnetic block 6 are in contact, the ejector 10 can be fixed by mutual attraction between the second magnetic block 11 and the first magnetic block 6.

[0025] The limit clamping groove 12 is arranged on one side of the ejector 10 close to one end of the first spring 9. The stop plate 13 is rotatably connected to the middle section and the side plate 3 and is arranged on the inner wall of the accommodating cavity 7 close to one side of the limit clamping groove 12. The middle section of the stop plate 13 is fixedly provided with a pin shaft 14. The two side plates 3 are both provided with a positioning pin hole 15. The end of the pin shaft 14 penetrates through the side plate 3 through the positioning pin hole 15 and is rotatably connected to the side plate 3. When one end of the stop plate 13 is stressed, the stop plate 13 can rotate by a certain angle around the pin shaft 14.

[0026] When the bottom end of the ejector 10 slides to the bottom end of the stop plate 13 and is clamped through the limit clamping groove 12, the first spring 9 is in a compressed state. When the bottom end of the stop plate 13 is separated from the limit clamping groove 12, the first spring 9 can eject the ejector 10 from the top opening of the accommodating cavity 7 under the action of the elastic force. At this time, the compression length of the first spring 9 is less than the maximum compression length of the first spring 9, which can avoid the problem that the first spring 9 is excessively compressed and deformed, resulting in the loss of the elastic force of the first spring 9.

[0027] The bottom end of the stop plate 13 is connected to the side wall of the accommodating cavity 7 through an elastic connecting piece. The elastic connecting piece includes a second spring 16 which is horizontally arranged on the inner wall of the accommodating cavity 7. One end of the second spring 16 away from the inner wall of the accommodating cavity 7 is fixed to the bottom end of the stop plate 13. When the second spring 16 is in a compressed state, the bottom end of the stop plate 13 rotates to be separated from the limit clamping groove 12 arranged on the bottom end side wall of the ejector 10. At this time, the first spring 9 can eject the ejector 10 from the top end of the accommodating cavity 7 through the elastic force of the first spring 9.

[0028] A through hole 17 is arranged on one side of the accommodating cavity 7 close to the top end of the stop plate 13. A trigger 18 is slidably arranged in the through hole 17. One end of the trigger 18 located in the accommodating cavity 7 abuts against the top end of the stop plate 13. When the user pushes the trigger 18 into the accommodating cavity 7 along the through hole 17, the trigger 18 will push the two ends of the stop plate 13 to rotate in opposite directions around the pin shaft 14, so that the bottom end of the stop plate 13 rotates and presses the second spring 16, until the bottom end of the stop plate 13 is separated from the limit clamping groove 12 arranged on the ejector 10. After the trigger 18 is released, the second spring 16 in a compressed state can reversely push the stop plate 13 to reset.

[0029] A plurality of magnetic rings 19 are slidably arranged on the key ring 2. The adjacent ends of the plurality of magnetic rings 19 are magnetically opposite. After a plurality of keys are hung on the key ring 2, the magnetic rings 19 can be arranged to be spaced apart from the keys by sliding the magnetic rings 19. At this time, the magnetic rings 19 can magnetically attract each other to clamp the keys, so that the plurality of keys form an integral structure together, so as to avoid the problem that the keys are rubbed with each other when they are vibrated or subjected to external force, which not only easily wears the coating on the surface of the keys, but also generates a large noise.

[0030] It should be noted that the key ring with magnetic attraction and elastic jump pendant, in use, the user can extrude trigger 18 into through hole 17, make trigger 18 push both ends of stop plate 13 around pin shaft 14 reverse rotation, the bottom end of stop plate 13 rotation will extrude second spring 16 shrink, until the bottom end of stop plate 13 to the limit of the card slot 12 on the ejector 10 is disengaged, at this time the ejector 10 loses the limiting effect of stop plate 13, under the action of the elastic force of first spring 9 along the guide slot 5 from the top opening of containing cavity 7 eject, when the second magnetic block 11 installed in the middle section of ejector 10 slip to with first magnetic block 6 adhere, can be fixed through the mutual attraction of first magnetic block 6 and second magnetic block 11 to ejector 10, after ejector 10 eject, the user can press ejector 10 into containing cavity 7, when the bottom end of ejector 10 slide to with stop plate 13 adhere, can be through the bottom end of ejector 10 push stop plate 13 bottom end rotation, until the bottom end of ejector 10 again through the limit of the card slot 12 and stop plate 13 card, that is, the ejector 10 can be completely contained in containing cavity 7, using the eject and reset of ejector 10, not only increase the function of the decorative pendant, but also greatly improve the interesting of the use of decorative pendant.

[0031] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as limiting the scope of the present application. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, a number of variations and improvements can be made, which belong to the protection scope of the present application.
