Description

Technical Field

[0001] The utility model relates to the field of precision mechanical connection and product structure design, and more specifically, to an interlocking structure. Background Art

[0002] In the fields of baby products, food containers, and outdoor equipment, the connection method between components is crucial for the overall performance of the product. Traditional connection methods mainly rely on means such as threads, buckles, or welding. Although these methods can achieve basic connections, many problems often emerge in actual use.

[0003] In the field of baby products, the connection between the nipple and the bottle body of a baby bottle is a key part. The traditional threaded connection may become loose due to wear during frequent use, resulting in milk leakage; although the snap connection is convenient, it is easily affected by material fatigue, leading to breakage or snap failure. In addition, these connection methods are also inconvenient for cleaning and maintenance, especially for baby products with high hygiene requirements.

[0004] The connection between the lid and the body of a food container such as a food storage box also faces similar challenges. Poor sealing will cause food spoilage, and traditional connection methods are insufficient in terms of sealing effect and durability. In the field of outdoor equipment, especially products such as sports water bottles, the connecting components not only require firmness and durability but also need to have shock resistance and easy operation characteristics. Traditional connection methods may not provide sufficient reliability in harsh outdoor environments.

[0005] In response to the above problems, interlocking structures have gradually been applied in these fields. Through delicate geometric designs, interlocking structures enable a firm combination between connecting components without the need for additional fasteners, while simplifying the assembly and disassembly processes and reducing manufacturing costs. Compared with traditional connection methods, interlocking structures perform better in terms of safety, durability, and ease of cleaning.

[0006] Although existing interlocking structures have achieved good results in certain specific applications, their designs are often too complex, restricting their widespread use in different application scenarios.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0035] An interlocking structure, as Figures 1 - 3 shown, includes a first locking structure 1 and a second locking structure 3. The first locking structure 1 is arranged on the connecting ring 5 and includes a first locking rib 101. The first locking rib 101 includes a first tightening part 102 and a first limiting part 103, and its first end face 104 is an arc surface.

[0036] The second locking structure 3 is arranged on the fitting 6 and includes a second locking rib 301. The second locking rib 301 includes a first locking part 302 and a second limiting part 303, and its second end face 304 is also an arc surface. The first locking rib 101 of the first locking structure 1 and the second locking rib 301 of the second locking structure 3 are correspondingly arranged, ensuring a tight fit between the connecting ring 5 and the fitting 6.

[0037] In practical applications, the thickness of the first tightening part 102 is greater than the thickness of the first limiting part 103, so that during the locking process, the first locking rib 101 can firmly contact and fix with the second locking rib 301. In addition, reinforcing ribs can be provided on the surfaces of the first locking rib 101 and the second locking rib 301 to improve the overall strength and durability of the structure.

[0038] The materials of the first locking structure 1 and the second locking structure 3 can be selected from plastics or metals, depending on specific application requirements. This interlocking structure has a simple design, is suitable for various mechanical structures requiring stable connections, and has a low manufacturing cost and an efficient production process.

[0039] Embodiment 1:

[0040] An interlocking structure for a feeding bottle

[0041] In this embodiment, the interlocking structure is used for the connection between the nipple and the bottle body of a feeding bottle, aiming to provide a stable and convenient connection method to ensure no liquid leakage during use and easy disassembly and cleaning.

[0042] 1. Structural composition

[0043] The interlocking structure of this embodiment includes:

[0044] The first locking structure 1: It is arranged on the connecting ring of the nipple and includes a plurality of first locking ribs 101. Each first locking rib has a first tightening part 102 and a first limiting part 103, and the first end face 104 is an arc surface.

[0045] The second locking structure 3: It is arranged on the outer wall of the upper part of the milk bottle and includes a plurality of second locking ribs 301. Each second locking rib has a first locking part 302 and a second limiting part 303, and the second end face 304 is an arc surface.

[0046] The locking bump 2: It is arranged on the inner wall of the connecting ring.

[0047] The limiting bump 4: It is arranged at the corresponding position on the outer wall of the milk bottle.

[0048] 2. Connection process

[0049] When the nipple needs to be connected to the milk bottle, the user first aligns the connecting ring of the nipple with the upper part of the milk bottle, so that the first locking ribs 101 are inserted between two adjacent second locking ribs 301. At this time, the first tightening part 102 is above the second locking part 302.

[0050] The user rotates the connecting ring clockwise, so that the first tightening part 102 gradually slides under the second locking part 302 and fits tightly with it. At the same time, the first limiting part 103 approaches and fits with the second limiting part 303. During the tightening process, the locking bump 2 contacts the limiting bump 4, further preventing the accidental rotation of the connecting ring.

[0051] Through this tightening operation, the nipple and the milk bottle are firmly connected, ensuring that there will be no loosening or liquid leakage during the feeding process.

[0052] 3. Disassembly process

[0053] When the nipple needs to be disassembled, the user can rotate the connecting ring counterclockwise, so that the first locking ribs 101 gradually disengage from the second locking ribs 301. Since the first end face 104 and the second end face 304 are arc-shaped designs, the connecting ring will gradually move upward under the guidance of the arc surface during the rotation until it is out of the locked state. At the same time, the cooperation between the locking bump 2 and the limiting bump 4 also ensures that the connecting ring will not loosen by itself without external force.

[0054] 4. Structural advantages

[0055] The interlocking structure of this embodiment has the following advantages:

[0056] Stability: Through the close cooperation of the first tightening part 102 and the first limiting part 103 with the second locking structure, high strength and stability of the connection are achieved.

[0057] Easy to operate: Users can install and remove the nipple with a simple rotation operation, which is convenient.

[0058] Leak - proof design: The tight interlocking structure ensures that the milk bottle does not leak during use, improving the safety of use.

[0059] Easy to clean: The structure is simple without complex mechanical parts, easy to disassemble and clean, ensuring the hygiene of the milk bottle.
