Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a multi-functional water tank structure for RVs. Background Technology

[0002] A motorhome (RV) is a special type of vehicle that not only serves as a means of transportation but also provides living and accommodation functions. RVs are typically equipped with a sink, a feature that allows for basic water needs during travel or camping, such as washing dishes, washing hands, or preparing simple food. The sink's design usually considers the efficient use of space and is coordinated with the overall layout of the RV, ensuring practicality without taking up too much space. This feature greatly enhances the convenience and comfort of the RV, allowing people to enjoy outdoor life while also experiencing a degree of home comfort. Therefore, the sink, as an important component of an RV, provides significant assistance to users and makes RV living more similar to the conveniences of everyday family life.

[0003] Existing RV water tanks typically consist only of the tank body and a cover hinged to it, offering only basic washing functionality. Therefore, designing a multi-functional water tank structure for RVs is essential. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-functional water tank structure for RVs.

[0005] To achieve the above objectives, the technical solution of this utility model is: a multi-functional water tank structure for RVs, comprising a water tank body installed on an RV platform, characterized in that a left cover and a right cover are connected to the water tank body by multiple hinges, and a handle is fixed on both the left and right covers. A rubber strip is fixed on the side of the left cover near the right cover, an auxiliary opening is provided on the right cover, a drain basket is fixed at the auxiliary opening, and a sealing plate that can close the auxiliary opening is slidably mounted on the right cover, the sealing plate having a handle.

[0006] A mounting shaft is rotatably connected to the right cover on the side near the left cover, and the mounting shaft is fixedly connected to the cup holder via an extension arm.

[0007] An elastic positioning block that mates with the right cover is fixed on the extended arm.

[0008] The side of the left cover is secured with a rubber strip by multiple screws.

[0009] By adopting the above technical solution, the beneficial effects of this utility model are: This utility model features a left and right cover, with a drain basket and cup holder added to the right cover. After washing fruits and vegetables, the drain basket can be used to drain the water. At the same time, the cleaned water cup can be inverted on the cup holder to drain the water, which can drip directly into the sink body, thus making full use of the space of the sink body.

[0011] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0012] like Figure 1-3 As shown, this RV uses a multi-functional water tank structure, including a water tank body 5 installed on the RV platform 1. The water tank body 5 is connected to a left cover 2 and a right cover 4 by multiple hinges 10. In this embodiment, the left cover 2 can be opened upwards alone, or the left cover 2 can be opened first and then the right cover 4 can be opened, or both the left cover 2 and the right cover 4 can be opened upwards together. The hinges 10 can keep the left cover 2 or the right cover 4 in an open or closed state, which is the existing technology. When the state needs to be switched, the user can change the state by holding the handle 3. The left cover 2 and the right cover 4 are both fixed with handles 3. The side of the left cover 2 near the right cover 4 is fixed with a rubber strip 8. The right cover 4 has an auxiliary opening, and a drain basket 6 is fixed at the auxiliary opening. A sealing plate 7 that can close the auxiliary opening is slidably mounted on the right cover 4. The sealing plate 7 has a handle 12. There is a certain frictional resistance between the sealing plate 7 and the right cover 4. The sealing plate 7 can only move when the user pulls the handle 12. This can be achieved by the existing technology.

[0013] A mounting shaft 9 is rotatably connected to the side of the right cover 4 near the left cover 2. The mounting shaft 9 is fixed to the cup holder 11 via an extension arm 13. An elastic positioning block 14 that cooperates with the right cover 4 is fixed on the extension arm 13. After the left cover 2 is opened, the cup holder 11 can be rotated out from the right cover 4. Due to the elastic positioning block 14, which abuts against the right cover 4, the cup holder 11 will not move accidentally relative to the right cover 4. The cup can be placed upside down in the cup holder 11. The positioning of the cup by the cup holder 11 adopts existing technology. Although the elastic positioning block 14 always abuts against the right cover 4, the cup holder 11 can still rotate normally when the user rotates it.

[0014] A rubber strip 8 is fixed to the side of the left cover 2 by multiple screws. With this structure, when both the left cover 2 and the right cover 4 are closed, the rubber strip 8 seals the gap between them.

[0015] In this utility model, a left cover 2 and a right cover 4 are designed, and a drain basket 6 and a cup holder 11 are added to the right cover 4. By opening the left cover 2 and closing the right cover 4, the fruits and vegetables washed in the sink body 5 can be directly placed into the drain basket 6. After the fruits and vegetables are washed, the drain basket 6 can be used to drain the water. At the same time, the cleaned cup can be inverted on the cup holder 11 to drain the water, and the water can drip directly into the sink body 5, thus making full use of the space of the sink body 5.

[0016] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0017] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
