Description
Technical Field
[0001] The utility model relates to the technical field of backpacks, and more specifically, to a backpack for preventing tennis rackets from falling off. Background Art
[0002] A backpack refers to a bag carried on the back, with diverse materials, such as genuine leather, plastic, polyester, canvas, nylon, cotton and linen texture suitcases. Tennis players often use tennis backpacks to store and hold their rackets.
[0003] After retrieval, a racket sports backpack with the existing publication number CN218457590U includes a bag body and shoulder straps. An accommodation space is formed inside the bag body. A support plate is arranged inside the accommodation space, and the support plate is fixedly connected to the bag body. A support frame is movably connected to the support plate. The support frame is provided with a connecting member detachably connected to the racket rod, and the support plate is provided with a limiting component for restricting the movement between the support frame and the support plate. It can support the racket, and when the racket is not placed, the support frame will not affect the appearance and normal use of the backpack, improving the applicability of the backpack.
[0004] For common racket backpacks, a storage bag is sewn on the outer surface of the bag body. After the racket is inserted into the storage bag, the handle of the racket is exposed outside. During the process of the athlete carrying the backpack and walking or running, the racket is prone to displacement and even falling off, and the stability is not good. Therefore, we propose a backpack for preventing tennis rackets from falling off to solve the above-mentioned problems. Content of the Utility Model
