Description

Technical Field

[0001] This utility model relates to the field of backpack accessories technology, specifically a backpack cover. Background Technology

[0002] Schoolbags are a common tool for students to carry books and stationery. During use, the bottom of schoolbags easily gets dirty. To prevent this, the applicant previously invented a schoolbag cover. When using the cover, it is placed over the bottom of the schoolbag. When the cover gets dirty, it can be easily removed from the bottom of the schoolbag for washing. Washing the cover requires significantly less work compared to washing the entire schoolbag. To facilitate the pulling out of the shoulder straps at the bottom of the cover, an opening is provided on both sides of the bottom. Before threading the straps through the opening or pulling them out, the straps must first be opened, making the cover inconvenient to use. Furthermore, some backpack straps cannot be opened, rendering the cover unusable. The applicant also found that while a larger opening facilitates the threading and unfolding of straps of varying widths, an excessively large opening causes the cover to frequently slip downwards during use, resulting in an unsightly appearance. Conversely, a smaller opening makes it difficult to thread wider straps through, reducing the cover's flexibility. Utility Model Content

[0016] The following will describe specific embodiments and appendices. Figures 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] This utility model provides a backpack cover (such as...) Figure 1As shown), it includes a sleeve body 1, which is cylindrical. The upper part of the sleeve body 1 has an upper opening 11, and the bottom of the sleeve body 1 is closed. In actual use, the bottom of the backpack is directly inserted into the sleeve body 1 through the upper opening 11, thus achieving the sleeve body 1 fitting over the bottom of the backpack. To improve the flexibility and waterproofness of the sleeve body 1, waterproof fabric can be used for sewing during the actual manufacturing process. A side opening 2 is provided on both the left and right sides of the front sidewall 12 of the sleeve body 1. The side opening 2 extends upward from the bottom of the front sidewall of the sleeve body and passes through the edge of the upper opening 11, allowing the upper part of the side opening 2 to be fully opened. If the upper part of the side opening 2 can be fully opened, then... With the backpack straps closed, the bottom of the straps can be easily placed inside the side opening 2, allowing the bottom of the straps to penetrate the side wall of the protective cover body 1 from the inside out. This makes the combination of the protective cover body 1 and the bottom of the backpack convenient. When the upper part of the side opening 2 is fully open, the bottom of the backpack straps can be easily removed from the side opening 2 without opening the backpack straps, thus facilitating the separation of the protective cover body 1 from the bottom of the backpack and making it easier to clean the protective cover body 1 daily. A fastening component 3 is provided on the upper middle part of the side opening 2. The fastening component 3 is used to open or close the upper middle part of the side opening 2. That is, the fastening component 3 can fasten and disengage. When the fastening component 3 is disengaged, the upper part of the side opening 2 is opened. When the fastening component 3 is fastened, the upper part of the side opening 2 is fastened. In practical applications, the side opening 2 can be divided into a snap-locked closed area 22 and a normally open area 23. The snap-locked closed area 22 is located in the upper middle part of the side opening 2, and the normally open area 23 is located in the lower middle part of the side opening 2. In practical use, the snap-locked closed area 22 can be opened or closed according to actual needs using the snap-locking component 3, while the normally open area 23 is always in a continuous state. After the protective cover body 1 is fitted into the bottom of the backpack, the bottom of the backpack strap is fitted into the normally open area 23, and the snap-locked closed area 22 is in a snap-locked closed state. When the backpack is carried, the backpack strap is in a taut and straight state. At this time, the lower part of the snap-locked closed area 23 can basically rest against the backpack strap, and thus, to a certain extent, the taut and straight backpack strap can be used to support the protective cover body 1 against falling.

[0018] Based on the above embodiments, after the sheath body 1 is placed on the bottom of the schoolbag, in order to facilitate the sheath body 1 to effectively wrap around the outside of the schoolbag, an elastic band 111 is provided on the edge of the upper opening 11. The elastic band 111 is used to make it easy for the upper opening 11 to open or close.

[0019] Based on the above embodiments, to facilitate the adjustment of the fastening and closing length of the fastening and closing area 22, so that the side opening 2 can accommodate backpack straps of different widths and prevent the sheath from slipping down during use, three specific embodiments of the fastening component 3 are designed. The specific implementation of the first specific embodiment of the fastening component 3 is as follows: the fastening component includes a row of hooks and a row of buckles. The hooks and buckles are known and mature technologies in the prior art. For example, in the existing bra technology field, hooks and buckles are often used as connecting parts. A row of hooks and a row of buckles are respectively set on the two edges 21 of the upper middle area of ​​the side opening 2. Specifically, the row of hooks includes several hooks 32, which are distributed at equal intervals along the corresponding edges 21. The row of buckles includes several rows of buckles 31, which are distributed at equal intervals along the corresponding edges 21. By fastening the hooks 32 into the corresponding buckles 31, the two edges 21 are fastened. Furthermore, in actual application, the corresponding number of hooks 32 and buckles 31 can be fastened according to actual needs, thereby adjusting the fastening length. The second specific embodiment of the fastening component 3 is as follows: The fastening component includes several concealed buckles, which are known mature technologies in the existing technical field. Therefore, the specific structural features and working principle of the concealed buckles will not be described in detail here. The female buckles and female buckles of the several concealed buckles are respectively set on the two edges 21 of the upper middle region of the side opening 2. The two edges 21 are matched by the combination of the female buckles and the female buckles. The fastening length can be adjusted by adjusting the number of the fastened concealed buckles. The specific implementation of the third specific embodiment of the fastening component 3 is as follows: The fastening component includes at least one set of hook and loop fasteners. The male and female sides of the hook and loop fasteners are respectively disposed on the two edges 21 of the upper middle region of the side opening 2. In actual application, when the length of the hook and loop fasteners is long, the fastening component can be a set of hook and loop fasteners. The fastening length can be adjusted by adjusting the pasting length of the male and female sides of the set of hook and loop fasteners. When the length of the hook and loop fasteners is short, multiple sets of hook and loop fasteners can be provided. Multiple male or female sides are distributed at equal intervals along the corresponding edges 21. The fastening length can be adjusted by adjusting the number of hook and loop fasteners.

[0020] When actually using this backpack cover, first open the fastening components on the fastening and closing area 22. Then, place the backpack strap inside the side opening 2 and make the bottom of the backpack strap as close as possible to the bottom of the normally open area 23. After it is close, perform the fastening operation. When performing the fastening operation, make the bottom of the fastening and closing area 22 as close as possible to the top of the backpack strap. In this way, after carrying the backpack, the top of the backpack strap can be used to block the cover and prevent the cover from sliding down.
