Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, specifically to a sealing and anti-loosening structure and a faucet. Background Technology

[0002] As faucet functions increase, the internal water channels of the faucet body become more numerous and complex. To facilitate molding, most existing faucet bodies use plugs to seal these channels. For example, Chinese patent CN222316011U discloses a shower faucet's water distribution core that uses a plug and pin structure to seal the water channels. Other solutions use plugs connected to spring clips to fix them to the water channels. In these structures, whether it's a pin or a spring clip, an additional component is needed on top of the plug, increasing cost. Furthermore, these small components are easily lost during disassembly, and leaks occur if the pin or spring clip loosens or falls off during assembly. To address this, some designs incorporate threads on the plug, connecting to threads on the water channels to reduce the number of components. However, forming these threads in the mold is complex, increasing mold costs and injection molding time, thus raising the cost of the plug. Utility Model Content

[0003] This utility model discloses a sealing and anti-loosening structure, which is simple in structure and convenient in operation, and aims to improve the problems of easy loosening and high cost of existing waterway sealing structures.

[0004] The present invention adopts the following solution:

[0005] A sealing and anti-loosening structure includes an assembly portion disposed on a waterway and a plug for connecting to the assembly portion. The assembly portion includes a mounting hole communicating with the waterway, a slot disposed on the side wall of the mounting hole, a sliding groove communicating with the slot, and an anti-rotation groove located on the end face of the mounting hole. The plug has a sealing section, a locking block, and an anti-rotation head. The sealing section extends into the mounting hole and is fitted with a sealing ring for sealing with the mounting hole. The locking block can be inserted along the sliding groove and rotated to engage with the slot, thereby limiting the plug axially. The anti-rotation head is configured to embed into the anti-rotation groove when the locking block engages with the slot, thereby limiting the plug circumferentially.

[0006] As a further improvement, two slots and anti-rotation slots are symmetrically arranged along the center of the mounting hole.

[0007] As a further improvement, a straight handle protrudes from the end face of the plug away from the sealing section, and the anti-rotation head is disposed at both ends of the handle.

[0008] As a further improvement, the anti-rotation head has an inclined surface that is tilted in the screwing direction, and the locking block is provided with a chamfer in the screwing direction.

[0009] As a further improvement, the slot is provided through the side wall of the mounting hole, and the core-pulling direction of the mounting hole, the anti-rotation groove, and the sliding groove is the same as the core-pulling direction of the waterway.

[0010] As a further improvement, the depth of the anti-rotation groove is no greater than the gap between the top surface of the locking block and the locking groove.

[0011] As a further improvement, the locking block is provided to protrude outward along the outer wall of the plug.

[0012] As a further improvement, the size of the mounting hole is larger than the inner diameter of the waterway, so that a limiting surface is formed between the mounting hole and the waterway to limit the insertion depth of the plug.

[0013] As a further improvement, the sealing section is provided with at least two sealing grooves for assembling sealing rings.

[0014] Another type of faucet is provided, including a faucet body, wherein the faucet body is provided with a plurality of water channels, and each water channel is provided with a sealing and anti-loosening structure as described in any of the preceding claims.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] 1. This application requires only a single plug to seal the waterway, and the plug has a simple structure, resulting in a simple mold structure that eliminates the need for complex structures such as threads. This reduces mold costs and injection molding time, thereby lowering the cost of sealing the waterway. Furthermore, the anti-rotation head prevents the plug from loosening, ensuring reliable sealing and preventing leaks and drips.

[0017] 2. A straight handle is protruding on the end face of the plug away from the sealing section. When disassembling or assembling, the handle can be turned directly by hand without the need for other tools or jigs. This is convenient, quick, and conducive to the cleaning of the waterway.

[0018] 3. Only one core slider is needed to form the waterway, mounting hole, anti-rotation groove, and slide. The retaining groove can be set on the male or female mold, thus simplifying the mold structure and reducing mold costs. At the same time, the sealing section, retaining block, and anti-rotation head of the plug do not require a core-pulling structure for mold forming, thereby further reducing mold costs.

[0031] Combination Figures 1 to 8 This embodiment provides a sealing and anti-loosening structure, including an assembly part 2 disposed on a waterway 11 and a plug 3 for connecting with the assembly part 2. The assembly part 2 includes a mounting hole 21 communicating with the waterway 11, a slot 22 disposed on the side wall of the mounting hole 21, a sliding groove 23 communicating with the slot 22, and an anti-rotation groove 24 located on the end face of the mounting hole 21. The plug 3 has a sealing section 31, a locking block 32, and an anti-rotation head 33. The sealing section 31 extends into the mounting hole 21 and is fitted with a sealing ring for sealing with the mounting hole 21. The locking block 32 can be inserted along the sliding groove 23 and rotated to engage with the slot 22, so that the plug 3 is axially limited. The anti-rotation head 33 is configured to embed into the anti-rotation groove 24 when the locking block 32 engages with the slot 22, so that the plug 3 is circumferentially limited.

[0032] During installation, the retaining block 32 on the plug 3 is inserted along the sliding groove 23, so that the sealing section 31 is inserted into the mounting hole 21, and the corresponding sealing ring seals with the mounting hole 21, thereby sealing the waterway 11. Then, the retaining block 32 is rotated onto the retaining groove 22, so that the plug 3 is axially limited, and at the same time, the anti-rotation head 33 is embedded in the anti-rotation groove 24 to limit the rotation of the plug 3, thereby preventing the plug 3 from loosening.

[0033] It should be noted that in this embodiment, only the plug 3 is needed to seal the water channel 11. Furthermore, the plug 3 has a simple structure, and the corresponding mold structure is also simple, eliminating the need for complex structures such as threads. This reduces mold costs and injection molding time, thereby lowering the cost of sealing the water channel 11. In addition, the anti-rotation head 33 prevents the plug 3 from loosening, ensuring the reliability of the seal and preventing leaks and drips.

[0034] In a preferred embodiment, two slots 22 and two anti-rotation grooves 24 are symmetrically arranged along the center of the mounting hole 21 to ensure balanced force on the plug 3 and further prevent the plug 3 from loosening. In other embodiments, multiple slots 22 and multiple anti-rotation grooves 24 are arranged in a central array, without specific limitation.

[0035] Based on the above embodiments, in an optional embodiment of this utility model, a straight handle 34 protrudes from the end face of the plug 3 away from the sealing section 31, and anti-rotation heads 33 are disposed at both ends of the handle 34. During disassembly and assembly, the handle 34 can be turned directly by hand without the aid of other tools or jigs, which is convenient and quick and beneficial to the cleaning of the waterway 11.

[0036] Preferably, the anti-rotation head 33 has an inclined surface 331 along the screwing direction, and the locking block 32 is chamfered in the screwing direction to facilitate the anti-rotation head 33 screwing into the anti-rotation groove 24 and the locking block 32 screwing into the locking slot 22, reducing the operating force. The screwing direction is defined as the direction from the sliding groove 23 to the locking slot 22. Further, the depth of the anti-rotation groove 24 is not greater than the gap between the top surface of the locking block 32 and the locking slot 22, that is, the gap between the top surface of the locking block 32 and the locking slot 22 is sufficient for the axial movement space of the anti-rotation head 33, so that the anti-rotation head 33 can be embedded in the anti-rotation groove 24.

[0037] Preferably, the slot 22 is provided through the side wall of the mounting hole 21, and the core-pulling direction of the mounting hole 21, the anti-rotation groove 24 and the slide groove 23 is the same as the core-pulling direction of the water channel 11. That is, only one core slider needs to be set at the water channel 11 to form the water channel 11, the mounting hole 21, the anti-rotation groove 24 and the slide groove 23. The slot 22 can be set on the male mold or the female mold, thereby simplifying the mold structure and reducing the mold cost.

[0038] In another embodiment, the locking block 32 protrudes outward along the outer wall of the plug 3. After the locking block 32 is inserted along the slide groove 23, it is rotated to the locking groove 22 to engage with it. In an optional embodiment, the slide groove 23 and the locking groove 22 have L-shaped cross-sections. The slide groove 23 is vertically arranged from the end face of the mounting hole 21, and the locking groove 22 is arranged horizontally.

[0039] Based on the above embodiments, in an optional embodiment of this utility model, the size of the mounting hole 21 is larger than the inner diameter of the water channel 11, so that a limiting surface 211 is formed between the mounting hole 21 and the water channel 11 to limit the insertion depth of the plug 3, ensuring the sealing of the sealing section 31 and the mounting hole 21, as well as the position of the locking block 32 and the locking groove 22. Preferably, at least two sealing grooves 311 for assembling the sealing ring are provided on the sealing section 31 to further ensure the reliability of the seal. In this embodiment, the molding of the sealing section 31, the locking block 32, and the anti-rotation head 33 on the plug 3 does not require a core-pulling structure, thereby reducing mold costs and molding time.

[0040] This utility model also provides a faucet, including a faucet body with multiple water channels 11, each water channel 11 having a sealing and anti-loosening structure as described in any of the above embodiments. This simplifies the structure of the faucet body 1, facilitates mold making of the faucet body 1, and improves the assembly efficiency of the faucet body 1 by providing a sealing and anti-loosening structure.

[0041] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
