Description

Technical Field

[0001] The utility model relates to the technical field of sports goods, in particular to a race number plate backpack. Background Art

[0002] In sports events, in order to better distinguish the contestants, number plates are usually used to identify the contestants. In professional sports events and fixed teams, there are generally special sportswear with numbers sewn on them. Each number represents a different contestant. However, when contestants participate in different competitions, they need to change into sportswear with different numbers. Therefore, contestants need to prepare multiple sets of sportswear, which is inconvenient to carry and wastes resources. Therefore, the patent document with application number 202220851737.4 in the prior art proposes a sportswear that is easy to replace the number plate. The above-mentioned problem is solved by sewing a cloth bag with a transparent cover on the sportswear. Although the sportswear is provided with structures such as elastic bands, Velcro and number plates, it is convenient for the quick replacement of number plates, but it also greatly increases the production cost of the sportswear.

[0003] However, in general temporary events such as staff conferences or school sports meets, the contestants are usually not professionals and will not buy special sportswear for themselves. The usual solution is to use temporary paper number plates fixed to the clothes with paper clips. After strenuous exercise, the paper number plates are likely to fall off due to sweat and shaking, which greatly affects the progress of the event. Therefore, a number plate carrier that takes into account both cost and replacement effect is needed to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a race number plate backpack to solve the above problem.

[0005] To achieve the above-mentioned purpose, a race number plate backpack is provided, comprising a textile layer and a plastic layer. The plastic layer is a rectangular structure, and a hot-melt layer is provided on all four edges of the plastic layer. The side of the textile layer close to the plastic layer is fixedly connected to the plastic layer through the hot-melt layer, and a bag opening seam is opened above the middle of the textile layer.

[0006] According to the race number plate backpack, the plastic layer is made of transparent material.

[0007] According to the race number plate backpack, the shape of the textile layer is the same as that of the plastic layer.

[0008] According to the race number plate backpack, the side of the plastic layer close to the textile layer is fixedly connected to the textile layer via a hot-melt layer.

[0009] According to the race number plate backpack, the textile layer is provided with trapezoidal edges corresponding to the edges of the plastic layer on all four sides, and the four trapezoidal edges are all equilateral trapezoids with forty-five angles.

[0010] According to the race number plate backpack, the edges of both sides of the plastic layer are fixedly connected to the main body edge of the textile layer and the corresponding trapezoidal edging through hot-melt layers.

[0011] The above solution has at least one of the following beneficial effects:

[0012] 1. The utility model is provided with a woven layer and a plastic layer, which are matched with a hot-melt layer. After simple cutting, a hot-pressing process can be directly performed on the edges of the woven layer and the plastic layer using a hot-pressing die corresponding to the hot-melt layer to form a hot-melt layer for connecting the woven layer and the plastic layer, so that the backpack can be directly formed in one piece. The processing procedure is simple, the material loss is extremely small, the production cost is greatly reduced, and the practicality of the device is enhanced.

[0013] 2. The present invention is provided with a woven layer and a transparent plastic layer, which are matched with the bag seam. When in use, the number plate can be directly placed facing the plastic layer, and then inserted between the woven layer and the plastic layer through the bag seam. The woven layer can then be connected to the athlete's clothing with a paper clip. When replacing, just remove the paper clip and you can directly replace it, which enhances the practicality of the device.

[0014] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0022] Example 1

[0023] Reference Figure 1 The embodiment of the present invention proposes a race number plate backpack, comprising a textile layer 1 and a plastic layer 2. The plastic layer 2 is a rectangular structure. The shape of the textile layer 1 is the same as that of the plastic layer 2. A hot-melt layer 3 is provided on all four edges of the plastic layer 2. The side of the plastic layer 2 close to the textile layer 1 is fixedly connected to the textile layer 1 through the hot-melt layer 3. A bag opening seam 4 is provided above the middle of the textile layer 1. After simple cutting, a hot press can be directly used to perform hot pressing treatment on the edges of the woven layer 1 and the plastic layer 2 through a hot pressing mold corresponding to the hot-melt layer 3 to form a hot-melt layer 3 for connecting the woven layer 1 and the plastic layer 2, so that the backpack is directly integrally formed, the processing procedure is simple, the material loss is extremely small, and the production cost is greatly reduced. However, the edges may become unbonded after long-term use.

[0024] Example 2

[0025] Reference Figure 2 and 3 , the difference between this embodiment and the first embodiment is that: a race number plate backpack includes a textile layer 1 and a plastic layer 2, the plastic layer 2 is a rectangular structure, the textile layer 1 is respectively provided with a trapezoidal edging 5 corresponding to the edge of the plastic layer 2, and the four trapezoidal edgings 5 are all equilateral trapezoids with forty-five angles, and a hot-melt layer 3 is provided at the edges of the plastic layer 2. The side of the textile layer 1 close to the plastic layer 2 is fixedly connected to the plastic layer 2 through the hot-melt layer 3, and the edges of both sides of the plastic layer 2 are respectively fixedly connected to the main body edge of the textile layer 1 and the corresponding trapezoidal edging 5 through the hot-melt layer 3. A bag opening seam 4 is opened in the upper middle part of the textile layer 1. Although the connection is more secure, the textile layer 1 needs to be cut more finely, and the edging process also needs to be performed before the hot pressing process, which increases the production cost.

[0026] Working principle: When using the utility model, the number plate is directly placed facing the plastic layer 2, and then inserted between the woven layer 1 and the plastic layer 2 through the bag seam 4, and then the woven layer 1 is connected to the athlete's clothes by a paper clip. When replacing, just remove the paper clip and you can directly replace it; and during production, only after simple cutting, directly use a hot press machine through a hot pressing mold corresponding to the hot melt layer 3 to perform hot pressing treatment on the edges of the woven layer 1 and the plastic layer 2 to form a hot melt layer 3 for connecting the woven layer 1 and the plastic layer 2, so that the backpack is directly molded in one piece, the processing procedure is simple, the material loss is extremely small, and the production cost is greatly reduced, while taking into account low cost and protection and replacement of the number plate.

[0027] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
