Technical Field
[0001] This utility model belongs to the field of sofa cover technology and relates to a sofa cover with waterproof effect. Background Technology
[0002] A sofa cover is a piece of fabric that is applied to a sofa. Its main purpose is to protect the original fabric of the sofa, extend its lifespan, and also add to its appearance and comfort.
[0003] Currently, sofa covers on the market are either completely waterproof or not waterproof at all. To meet the needs of families with children, it is necessary to design a sofa cover with waterproof properties that not only provides partial waterproofing but also allows for easy removal and installation for convenient use and cleaning. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a sofa cover with waterproof properties.
[0005] The objective of this utility model can be achieved through the following technical solution: A waterproof sofa cover, comprising a sofa cover body for wrapping the seat cushion, wherein the bottom of the sofa cover body has an opening, characterized in that the opening has four auxiliary parts, each of which is connected to a connecting component that can be quickly attached and detached from a ring-shaped locking cord, a waterproof pad is arranged on the upper part of the sofa cover body, and an elastic band is connected to the side of the waterproof pad, the elastic band being connected to the side of the sofa cover body by a double-sided zipper.
[0006] The connecting assembly includes a C-shaped fixed seat and a C-shaped movable seat. The C-shaped fixed seat is connected to an auxiliary part by a rope. The C-shaped movable seat is rotatably mounted on the C-shaped fixed seat. The middle part of the inner side of the C-shaped movable seat also has an anti-slip part.
[0007] The waterproof mat has a three-layer structure and is stitched together with edge banding to form a whole, including a cooling mat layer, a TPU film layer, and a short plush layer.
[0008] The sofa cover is made of a single piece of fabric sewn together.
[0009] Compared with existing technologies, this waterproof sofa cover has the following advantages:
[0010] This invention achieves partial waterproofing for sofa covers while ensuring quick assembly and disassembly by designing a waterproof pad that is easy to disassemble and install. Attached Figure Description

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0018] like Figures 1-5 As shown, this waterproof sofa cover includes a sofa cover body 1 for wrapping the seat cushion. The sofa cover body 1 has an opening at the bottom, and four auxiliary parts 1a at the opening. The sofa cover body 1 is made of a single piece of fabric sewn together. Each auxiliary part 1a is connected to a connecting component 5 that can be quickly attached and detached from the ring-shaped locking cord 6. A waterproof pad 4 is arranged on the upper part of the sofa cover body 1, and an elastic band 3 is connected to the side of the waterproof pad 4. The elastic band 3 is connected to the side of the sofa cover body 1 through a double-sided zipper 2. With this structure, the waterproof pad 4 can be easily connected to the sofa cover body 1, and the double-sided zipper 2 is located on the side of the sofa cover body 1, so it will not affect the normal use of the sofa.
[0019] The connecting component 5 includes a C-shaped fixed seat 5a and a C-shaped movable seat 5b. The C-shaped fixed seat 5a is connected to the auxiliary part 1a by a rope 7. The C-shaped movable seat 5b is rotatably mounted on the C-shaped fixed seat 5a. The inner middle of the C-shaped movable seat 5b also has an anti-slip part 5c. With this structure, after the sofa cushion is placed into the sofa cover, the ring locking rope 6 is inserted into the C-shaped movable seat 5b, and the C-shaped movable seat 5b is rotated so that it forms a closed loop with the C-shaped fixed seat 5a. The anti-slip part 5c and the ring locking rope 6 are firmly abutted together.
[0020] In practice, one of the two components, the sofa cover body 1 and the ring-shaped locking cord 6, has a certain degree of elasticity.
[0021] The waterproof pad 4 has a three-layer structure and is formed into a whole by stitching together with edge strips. It includes a cooling mat layer 4a, a TPU film layer 4b, and a short plush layer 4c. The waterproof pad 4 can be made using existing technology. With this structure, when the weather is hot, the cooling mat layer 4a can be placed on top, and when the weather is cold, the short plush layer 4c can be placed on top.
[0022] This invention achieves partial waterproofing for sofa covers while ensuring quick assembly and disassembly by designing a waterproof pad 4 that is easy to disassemble and install.
[0023] 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.
[0024] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
