Description

Technical Field

[0001] This utility model relates to the field of packaging accessories technology, and in particular to a rotary lock and packaging. Background Technology

[0002] In bag accessories, clasps primarily function to open and close the bag opening, ensuring the safety of the contents. The market offers a wide variety of clasps with different structures, including rotating, push-lock, and single magnetic clasps. Conventional clasps without magnetic closures leave the bag flap open when not engaged, offering no anti-theft function. The entire process requires two operations: opening and immediately closing the clasp, which is inconvenient. Push-locks, on the other hand, can be quite tight, causing hand pain after prolonged use, resulting in a poor user experience. Magnetic clasps only have a single magnetic closure function, making them easy to open and offering poor anti-theft performance. Therefore, this paper proposes a rotating clasp and bag accessory designed to address these issues. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1 and Figure 2As shown, to achieve the above objectives, this utility model provides a rotary lock, comprising: a first fixing seat 100 disposed on an outer first fabric and a second fixing seat 200 disposed on an outer second fabric, wherein both the first fixing seat 100 and the second fixing seat 200 are cylindrical, and a locking tongue 110 is disposed on the first fixing seat 100. The locking tongue 110 is generally L-shaped and includes an integrally disposed first extension section and a second extension section, which are perpendicular to each other. The second fixed base 200 has a through hole 210 for the locking tongue 110 to pass through. A rotating member 300 is rotatably mounted on the second fixed base 200. The rotating member 300 has a first annular boss 310, and the first annular boss 310 has a notch 311 for the locking tongue 110 to pass through. The notch 311 is positioned opposite to the through hole 210. After the locking tongue 110 passes through the through hole 210 and the notch 311, a slight manual force is applied to control the rotating member 300 to rotate forward relative to the second fixed base 200, which quickly locks the first fixed base 100 and the second fixed base 200. Controlling the rotating member 300 to rotate in the opposite direction relative to the second fixed base 200 quickly unlocks the first fixed base 100 and the second fixed base 200. The entire process can be operated with one hand, making it convenient, effortless, and providing a better user experience. Moreover, compared to magnetic latches, it is not easily opened after locking, providing better anti-theft performance.

[0029] It should be noted that when the rotary lock is placed vertically and the first fixed seat 100 and the second fixed seat 200 are in the unlocked state, the notch 311 and the through hole 210 coincide on the horizontal projection plane. At this time, the first annular boss 310 disengages from the locking tongue 110, and the locking tongue 110 can freely enter or exit the through hole 210 and the notch 311. When the first fixed seat 100 and the second fixed seat 200 are in the locked state, the notch 311 and the through hole 210 are offset from each other on the horizontal projection plane. At this time, the first annular boss 310 and the locking tongue 110 are tightly engaged.

[0030] In use, the second fixed seat 200 approaches the first fixed seat 100 until the locking tongue 110 penetrates the through hole 210. At this time, the rotating member 300 is controlled to rotate forward relative to the second fixed seat 200, so that the first annular boss 310 rotates forward relative to the locking tongue 110 by a certain angle, so that the first annular boss 310 and the locking tongue 110 are tightly engaged, thereby completing the quick locking between the first fixed seat 100 and the second fixed seat 200. The rotating member 300 is controlled to rotate in the opposite direction relative to the second fixed seat 200, so that the first annular boss 310 rotates in the opposite direction relative to the locking tongue 110 by a certain angle, thereby disengaging the first annular boss 310 from the locking tongue 110, thereby completing the quick unlocking between the first fixed seat 100 and the second fixed seat 200.

[0031] like Figure 2 and Figure 3 As shown, in some embodiments of this utility model, a fixing cover 400 is provided on the inner side of the rotating component 300. The fixing cover 400 is cylindrical in shape. The fixing cover 400 can seal the inner side of the rotating component 300 to prevent dust from entering the mating gap between the rotating component 300 and the second fixing seat 200, thereby ensuring a stable fit between the rotating component 300 and the second fixing seat 200. Additionally, a first mounting boss 410 is provided on the bottom surface of the fixed cover 400, and a first threaded hole is provided on the bottom surface of the first mounting boss 410. A first connecting hole 220 is provided on the top surface of the first fixed seat 100. A first screw passes through the first connecting hole 220 and is threaded into the first threaded hole to fix the fixed cover 400 onto the second fixed seat 200. At this time, the rotating component 300 can rotate freely relative to the fixed cover 400 and the second fixed seat 200. The fixed cover 400 and the second fixed seat 200 provide stable limiting for the rotating component 300, improve the fitting accuracy between the rotating component 300 and the second fixed seat 200, reduce mechanical wear between the rotating component 300 and the second fixed seat 200, and extend the service life of the overall rotary lock. Optionally, the fixed cover 400 is made entirely of zinc alloy, and its rust resistance can be increased by spraying a coating.

[0032] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments of this utility model, at least one mounting cavity 430 is provided on the bottom surface of the fixed cover 400. Optionally, two mounting cavities 430 are provided on the bottom surface of the fixed cover 400. An elastic member 440 is provided in the mounting cavity 430. The upper end of the elastic member 440 abuts against the top of the mounting cavity 430, and a ball bearing 450 is provided at the lower end of the elastic member 440. The ball bearing 450 protrudes from the mounting cavity 430 and abuts against the top surface of the first annular boss 310. When the rotating member 300 rotates relative to the first annular boss 310, the rolling engagement between the ball bearing 450 and the first annular boss 310 can reduce the frictional resistance between the rotating member 300 and the fixed cover 400, improve the smoothness of the rotating member 300 when rotating relative to the fixed cover 400, and avoid jamming. Meanwhile, the top surface of the first annular boss 310 can serve as a rolling support surface for the ball 450, preventing the ball 450 from dislodging from the mounting cavity 430 under the elastic force of the elastic element 440, thus ensuring the stability of the ball 450 within the mounting cavity 430. Preferably, the ball 450 is a steel ball, which has better wear resistance to ensure the service life of the ball 450.

[0033] like Figure 3 and Figure 7As shown, in some embodiments of this utility model, the top surface of the first annular boss 310 is provided with at least one first limiting groove 320 and at least one second limiting groove 330. Specifically, the top surface of the first annular boss 310 is provided with two first limiting grooves 320 and two second limiting grooves 330. The first limiting grooves 320 and the second limiting grooves 330 are respectively used for engaging with the ball 450. In the initial state, the ball 450 is located in the first limiting groove 320. At this time, the locking tongue 110 can freely enter or exit the through hole 210 and the notch 311. The first fixed seat 100 and the second fixed seat 200 are in the unlocked state. By engaging with the first limiting groove 320, the ball 450 can stabilize the rotating part 300 relative to the second fixed seat 200 in a fixed position, thus lifting... The stability of the first fixed seat 100 and the second fixed seat 200 when they are in the unlocked state is improved. When the rotating component 300 rotates 45° relative to the second fixed seat 200, the ball 450 moves from the first limiting groove 320 to the second limiting groove 330. At this time, the notch 311 and the through hole 210 are offset from each other on the horizontal projection plane. The first annular boss 310 and the locking tongue 110 are tightly engaged. The first fixed seat 100 and the second fixed seat 200 are in the locked state. The ball 450 can keep the rotating component 300 stable in a fixed position relative to the second fixed seat 200 by engaging with the second limiting groove 330, avoiding accidental displacement of the rotating component 300 relative to the second fixed seat 200, and improving the stability of the first fixed seat 100 and the second fixed seat 200 when they are in the locked state.

[0034] In some specific embodiments, the elastic element 440 is preferably a spring with an initial compression of 2-3 mm and an exposed height of 1-2 mm, so as to precisely control the damping force of the ball 450 rolling relative to the first annular boss 310 to be 3-6 N, and the rotation process is smooth. The diameter of the first limiting groove 320 and the second limiting groove 330 is 2.8 mm and the depth is 30 mil, so as to precisely control the locking force between the ball 450 and the first limiting groove 320 and the second limiting groove 330 to be set to 5-8 N, which can ensure that the rotating part 300 can be easily pushed when it needs to rotate, and can be stably fixed in position after the rotating part 300 stops rotating, so as to prevent the ball 450 from sliding out of the first limiting groove 320 or the second limiting groove 330 and losing its limit after the rotating part 300 stops sliding. Furthermore, when the ball 450 enters the corresponding first limiting groove 320 or second limiting groove 330, the ball 450 will collide with the surface of the first limiting groove 320 or second limiting groove 330 to produce a distinct clicking sound, indicating that the rotating part 300 has rotated into place, and the user has completed locking or unlocking the rotating lock.

[0035] In some embodiments of this utility model, the bottom surface of the fixed cover 400 has a second annular protrusion 460. The outer peripheral side of the second annular protrusion 460 is slidably connected to the inner peripheral side of the first annular protrusion 310. Through the sliding engagement of the second annular protrusion 460 and the first annular protrusion 310, the rotation of the rotating component 300 can be limited to a certain extent, effectively improving the movement accuracy of the rotating component 300, and making the switching between the first fixed seat 100 and the second fixed seat 200 between the locked and unlocked states smoother, effectively improving the overall user experience of the rotary lock. It should be noted that an avoidance groove 461 is provided on the outer peripheral side of the second annular protrusion 460. The avoidance groove 461 is used to accommodate the locking tongue 110, so that the locking tongue 110 can be stably engaged with the first annular protrusion 310. Moreover, when the rotary lock is placed vertically, the mounting cavity 430 is specifically located on the bottom surface of the second annular protrusion 460.

[0036] In some embodiments of this utility model, a positioning rib 312 is provided on the top surface of the first annular boss 310. The positioning rib 312 extends radially along the first annular boss 310. A positioning area 462 that cooperates with the positioning rib 312 is provided on the second annular boss 460. Optionally, the positioning area 462 is located in the circumferential position of the second annular boss, and the positioning area 462 is preferably an annular limiting groove. When the first fixed seat 100 and the second fixed seat 200 are in the locked state, the first end of the positioning area 462 abuts against the positioning rib 312 so that the ball 450 falls accurately into the corresponding first limiting groove 320. When the first fixed seat 100 and the second fixed seat 200 are in the unlocked state, the second end of the positioning area 462 abuts against the positioning rib 312 so that the ball 450 falls accurately into the corresponding second limiting groove 330. On the other hand, the precise cooperation between the positioning rib 312 and the positioning area 462 limits the relative position of the rotating part 300 between the first fixed seat 100 and the second fixed seat 200 in the locked and unlocked states, thereby preventing the rotating part 300 from being damaged due to excessive rotation and effectively improving the overall reliability of the rotary lock.

[0037] In some embodiments of this utility model, a first fixing washer 120 is provided on the bottom surface of the first fixing base 100, and two second mounting bosses 130 are integrally formed on the bottom surface of the first fixing base 100. The second mounting bosses 130 protrude from the bottom surface of the first fixing base 100, and a second threaded hole is provided at the center of the bottom end face of the second mounting bosses 130. A through second connecting hole 121 is provided on the top surface of the first fixing washer 120. The second connecting hole 121 and the second threaded hole are coaxially arranged, and a second screw passes through the second connecting hole 121 and is threadedly connected to the second threaded hole. During assembly, the outer first fabric is first attached to the bottom surface of the first fixing base 100 and the first fixing washer 120, and then the second screw is threaded through the second connecting hole 121 and the second threaded hole. By tightening the second screw, the first fixing washer 120 and the first fixing base 100 are tightly attached, thereby stably clamping the outer first fabric between the two. Similarly, the bottom surface of the second fixing base 200 is provided with a second fixing washer 230, and the bottom surface of the second fixing base 200 is also integrally formed with three third mounting bosses 240. The third mounting bosses 240 protrude from the bottom surface of the second fixing base 200, and a third threaded hole is opened at the center of the bottom end face of the third mounting bosses 240. A through third connecting hole 231 is opened on the top surface of the second fixing washer 230. The third connecting hole 231 and the third threaded hole are coaxially arranged. The second screw passes through the second connecting hole 231 and is threaded to the second threaded hole. During assembly, the outer second fabric is first attached to the bottom surface of the second fixing base 200 and the second fixing washer 230, and then the third screw is threaded through the third connecting hole 231 and the third threaded hole. By tightening the third screw, the second fixing washer 230 and the second fixing base 200 are tightly attached, thereby stably clamping the outer second fabric between the two. When the rotary lock is damaged and needs to be replaced, simply unscrew the second and / or third screws, improving the convenience of subsequent maintenance of the rotary lock.

[0038] The surface of the fixed cover 400 is provided with a rotation indicator mark 420, and the rotating part 300 is provided with a positioning mark 340. Preferably, the rotation indicator mark 420 is a locking mark and an unlocking mark engraved on the surface of the fixed cover 400, and the positioning mark 340 is a groove opened on the top surface of the rotating part 300. When the first fixed seat 100 and the second fixed seat 200 are in the locked state, the groove and the locking mark are located at the same radial position of the fixed cover 400. When the first fixed seat 100 and the second fixed seat 200 are in the locked state, the groove and the unlocking mark are located at the same radial position of the fixed cover 400. The user can intuitively understand the locked or unlocked state of the rotary lock, making it more convenient to use.

[0039] The working principle of this utility model is as follows: In the initial state, the first fixed seat 100 and the second fixed seat 200 are in the unlocked state, and the ball 450 is located in the first limiting groove 320. At this time, the locking tongue 110 can freely enter or exit the through hole 210 and the notch 311. When it is necessary to lock the first fixed seat 100 and the second fixed seat 200, the second fixed seat 200 moves closer to the first fixed seat 100 until the locking tongue 110 enters the through hole 210. The rotating member 300 is controlled to rotate forward relative to the second fixed seat 200, so that the first annular boss 310 rotates forward relative to the locking tongue 110 by a certain angle. The ball 450 moves from the first limiting groove 320 to the second limiting groove 330. The notch 311 and the through hole 210 are offset from each other on the horizontal projection plane. The first annular boss 310 and the locking tongue 110 are tightly engaged, thus completing the locking of the first fixed seat 100 and the second fixed seat 200.

[0040] In addition to the aforementioned rotary lock, this utility model also provides a bag that includes the rotary lock disclosed in the above embodiments. For the structure of other parts of the bag, please refer to the prior art, which will not be repeated here.

[0041] In summary, by controlling the rotating component 300 to rotate forward relative to the second fixed base 200, a quick locking between the first fixed base 100 and the second fixed base 200 can be achieved. The entire process can be operated with one hand, making it convenient, labor-saving, and providing a better user experience. Moreover, compared to magnetic clasps, it is not easily opened after locking, offering better anti-theft performance.

[0042] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0043] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model.
