Technical Field

[0001] This utility model relates to the field of lock and latch technology, specifically to a rotary box-opening lock and latch. Background Technology

[0002] In the field of packaging box locking technology, most existing locking methods are relatively traditional and simple, often focusing only on basic closing functions and failing to effectively leverage the added value that packaging can provide to products. Furthermore, in actual use, the operation is not simple or smooth enough, requiring consumers to spend considerable effort and time opening or closing the packaging, thus impacting the user experience.

[0003] In terms of the diversity of opening methods, the current market lacks packaging box lock designs that are both rotary-opening and extremely simple to operate. Furthermore, the current locks neither produce unique sound feedback to add fun to opening, nor do they have a reasonable pause design, making the rotating action lack rhythm and a sense of layering.

[0027] The present invention will be further described in conjunction with the following embodiments.

[0028] Depend on Figures 1 to 5 As can be seen, the rotary box lock described in this embodiment includes a circular rotating base 1 and an annular retaining ring 2 fixedly disposed at the bottom of the rotating base 1; a locking cavity 11 is formed between the rotating base 1 and the annular retaining ring 2; a circular locking member 3 is provided in the locking cavity 11; the locking member 3 is rotatably connected to the rotating base 1; a locking boss 4 is provided at the bottom of the locking member 3;

[0029] The rotary box lock also includes a locked component 6; the locked component 6 is provided with a locking tongue 7; the annular retaining ring 2 is provided with a clearance notch 21; the locking tongue 7 enters the locking cavity 11 after passing through the clearance notch 21;

[0030] The locking boss 4 is movably equipped with a sound-generating element 5; the inner wall of the rotating seat 1 is provided with a wave pattern 12; the sound-generating element 5 abuts against the wave pattern 12.

[0031] Specifically, in this embodiment, when the packaging box needs to be closed, the locking tongue 7 is first aligned with the clearance notch 21, and then the locked part 6 is inserted into the locking cavity 11. The locking tongue 7 enters the locking cavity 11 after passing through the clearance notch 21, so that the locked part 6 abuts against the locking part 3 and the locking boss 4 respectively. Then, by rotating the rotating seat 1, the annular retaining ring 2 rotates with the rotating seat 1, thereby causing the locking tongue 7 to be misaligned with the clearance notch 21, which completes the closure of the packaging box.

[0032] When the packaging box needs to be opened, the rotating seat 1 is rotated, and the annular retaining ring 2 rotates with the rotating seat 1, so that the locking tongue 7 is aligned with the clearance notch 21. Then the locked part 6 and the locking tongue 7 can be removed from the locking cavity 11, and the packaging box can be opened.

[0033] In addition, by setting the sound-emitting element 5 and the wave pattern 12, the sound-emitting element 5 continuously rubs against the wave pattern 12 during the rotation of the rotating seat 1, so that sound can be emitted and there is a sense of pause during the rotation of the rotating seat 1, and it is convenient for users to use.

[0034] In this embodiment, a rotary box-opening latch is provided, wherein the cross-sectional shape of the locking boss 4 and the cross-sectional shape of the locked part 6 are both semi-circular; the sound-generating element 5 is telescopically movably disposed on the arc side of the locking boss 4; the locking tongue 7 is disposed on the arc side of the locked part 6; the diameter side of the locking boss 4 abuts against the diameter side of the locked part 6; and the top of the locked part 6 abuts against the bottom of the locking element 3.

[0035] Specifically, when the locked part 6 is inserted into the locking cavity 11, the diameter side of the locking boss 4 abuts against the diameter side of the locked part 6, the top of the locked part 6 abuts against the bottom of the locking part 3, and the locking tongue 7 cannot be withdrawn from the locking cavity 11 due to the obstruction of the annular retaining ring 2, thereby making the connection between the locked part 6 and the locking part 3 secure.

[0036] In this embodiment, a rotary box-opening latch is provided, wherein the locking boss 4 is provided with a sound-generating cavity 41; the sound-generating component 5 is telescopically movably disposed in the sound-generating cavity 41; and a sound-generating spring 42 is provided between the sound-generating cavity 41 and the sound-generating component 5. The above arrangement can keep the sound-generating component 5 abutting against the wave pattern 12.

[0037] In this embodiment, a rotary box-opening lock is provided, wherein one end of the sound-emitting component 5 abuts against the wave pattern 12; the other end of the sound-emitting component 5 is provided with a first fixing pin 51; the bottom wall of the sound-emitting cavity 41 is provided with a second fixing pin 43; and the sound-emitting spring 42 is sleeved between the first fixing pin 51 and the second fixing pin 43; the above arrangement makes the overall structure stable and reliable.

[0038] The first fixing pin 51 has a first limiting block 52 on its side; the sound-emitting cavity 41 has a second limiting block 44 that abuts against the first limiting block 52. The above arrangement can prevent the sound-emitting component 5 from falling out of the sound-emitting cavity 41.

[0039] In this embodiment, a rotary box-opening lock is provided with a guide slope 53 on one side of the sound-generating component 5. This design facilitates the movement of the sound-generating component 5 along the wave pattern 12.

[0040] This embodiment of a rotary box-opening lock includes a locking cavity 61 for the locked component 6; a telescopic latch 7 is movably disposed within the locking cavity 61; and a locking spring 62 is provided between the locking cavity 61 and the latch 7. In this embodiment of the rotary box-opening lock, a guide slope 74 is provided at the top of one end of the latch 7. Since the packaging box needs to be rotated at a certain angle when locked, the guide slope 74 and the locking spring 62 facilitate the latch 7 entering the locking cavity 11.

[0041] In this embodiment, a rotary box-opening lock has a gap between one end of the locking tongue 7 and the wave pattern 12; the bottom wall of the locked cavity 61 is provided with a fourth fixing pin 63; the locking spring 62 is sleeved on the fourth fixing pin 63; the above arrangement makes the overall structure stable and reliable.

[0042] The other end of the latch 7 is provided with a third limiting block 72; the locked cavity 61 is provided with a fourth limiting block 64 that abuts against the third limiting block 72. The above arrangement can prevent the latch 7 from falling out of the locked cavity 61, and can limit the extension length of the latch 7, prevent the latch 7 from contacting the wave pattern 12, and at the same time ensure that the latch 7 can exit the locked cavity 61 from the clearance notch 21.

[0043] The rotary box lock described in this embodiment has a circular cover 8 fixedly connected to the top of the locking member 3; a rotating groove 81 is formed between the cover 8 and the locking member 3; the rotating base 1 is provided with a rotating ring 13; the rotating ring 13 is rotatably disposed in the rotating groove 81. The above configuration makes the overall structure stable and reliable.

[0044] The rotary box-opening lock described in this embodiment has a grooved groove 14 on the outer wall of the rotary base 1. This design helps to prevent slipping.

[0045] The rotating box lock described in this embodiment has a mark 15 on the top of the rotating base 1; this feature facilitates observation of whether the latch 7 and the clearance notch 21 are aligned.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
