Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of backpacks, in particular to a backpack with a waterproof function. Background Art
[0002] Backpacks are daily necessities that people often use to carry some necessary items when going to work, traveling, or exercising. However, existing backpacks are mainly made of cloth. When it rains or the humidity is high, the backpacks are easily wetted, allowing water from the outside to enter the backpack and soak the items inside, affecting the user experience. The overall waterproof effect of the backpack is poor.
[0003] After searching, the prior art authorization announcement number: CN213281906U discloses a backpack with good comfort, including a backpack main body and a backboard support component, wherein the backboard support component is arranged on the back of the backpack main body, and the backboard support component includes a first joint, a second joint, a third joint, a fourth joint, a fifth joint, a sixth joint and a strong rubber band. The first joint, the second joint, the third joint, the fourth joint, the fifth joint and the sixth joint are arranged on the back of the backpack main body. The utility model uses the backboard support component to be arranged on the back of the backpack with good comfort, which can prevent the backboard from deforming. When the waist section rotates left and right, because the backboard support component contacts the back, it generates a force on the fifth joint and the sixth joint, driving the cylindrical joint head to rotate in the cylindrical joint socket, so that the fifth joint and the sixth joint are always in fit with the waist according to the left and right rotation of the waist section. When the thoracic section flexes forward and extends backward, the back generates a force on the first joint, the second joint, the third joint and the fourth joint, thereby driving the saddle-shaped joint head to rotate in the saddle joint socket.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] See also Figure 1-5 In this embodiment, a backpack with a waterproof function includes a backpack 1. The backpack 1 is provided with a waterproof mechanism 2. The waterproof mechanism 2 includes an installation box 3 fixedly installed on the outer peripheral wall of the backpack 1. Two rotating shafts 4 are rotatably connected in the installation box 3. Rollers 5 are rotatably connected in the rotating shafts 4. A waterproof cover 6 is rotatably connected to the outer peripheral wall of the roller 5. The waterproof cover 6 is fixedly connected to a tension spring 7. Two shoulder straps 8 are fixedly connected to the front surface of the backpack 1.
