[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] As Figure 1 - Figure 6 shown, the present utility model provides a technical solution: a double-shoulder bag with a reflective function at night, including a backpack 1. A first reflective strip 2 is provided on the outside of the backpack 1. The first reflective strip 2 is installed at the front and both sides of the back, which can give timely reminders to the people on both sides and the front. A shoulder strap 15 is installed on the outside of the backpack 1, and a second reflective strip 16 is provided on the outside of the shoulder strap 15. Through the second reflective strip 16, a reflective warning can be given to the front of the user, solving the problem that the traditional double-shoulder bag only relies on the reflective components on the front for reminders, with large limitations and unable to well ensure the safety of the user when traveling at night, and having a better use effect.
[0026] A buffer layer 3 is provided inside the backpack 1, a fixed plate 4 is installed inside the backpack 1, and an isolation layer 14 is provided on the outside of the backpack 1. The buffer layer 3 and the isolation layer 14 are mainly composed of buffer sponges, which can buffer the bottom and the rear of the backpack 1. Coarse linen is woven inside the isolation layer 14, and the isolation layer 14 is composed of multiple horizontal strips, which is beneficial to improving the air permeability behind the user and enabling the user to use it better.
[0027] The outer surface of the fixing plate 4 is fixedly connected with a connecting shaft 5. The connecting shaft 5 is rotationally connected with a connecting plate 6. The outer surface of the connecting plate 6 is fixedly connected with a first support plate 7. Under the action of the connecting shaft 5 and the connecting plate 6, the first support plate 7 can be folded. When it is not necessary to carry out compressive treatment on the items inside the backpack 1, the first support plate 7 can be folded and retracted, which is convenient for the user to make better use of the internal space. There are two groups of the first support plates 7. When the first support plates 7 are opened, they rotate to both sides respectively, and can support both sides inside the backpack 1.
[0028] A second support plate 8 is slidably connected inside the first support plate 7. The second support plate 8 can slide inside the first support plate 7. When the first support plate 7 and the second support plate 8 are opened, a compressive area can be formed inside the backpack 1. Since the backpack 1 is made of a material with good anti-deformation ability, the items inside can be protected against compression by relying on the two first support plates 7, the second support plate 8 and the internal structure of the backpack 1. The position of the second support plate 8 can be adjusted according to the height of the items carried, which is convenient to achieve the best compressive effect.
[0029] A cross bar 9 is fixedly connected inside the second support plate 8. A baffle 10 is fixedly connected to the outer surface of the cross bar 9. A moving plate 11 is slidably connected to the outer surface of the cross bar 9. A plug rod 12 is fixedly connected to the outer surface of the moving plate 11. The position of the plug rod 12 can be controlled by the moving plate 11. Fixing holes 17 are formed inside the first support plate 7. The outer surface of the plug rod 12 is slidably connected with the inside of the fixing holes 17. There are multiple groups of fixing holes 17 and they are symmetrically arranged. When the plug rod 12 enters the inside of the fixing holes 17, the position of the second support plate 8 can be fixed. There are multiple groups of fixing holes 17, which can meet the adjustment requirements of different positions of the second support plate 8.
[0030] A spring 18 is sleeved outside the cross bar 9 between the baffle 10 and the moving plate 11. One end of the spring 18 is fixedly connected to the outer surface of the baffle 10, and the other end of the spring 18 is fixedly connected to the outer surface of the moving plate 11. The spring 18 can drive the plug rod 12 to reset, and can control the plug rod 12 to enter the inside of the fixing holes 17, ensuring the stability when the plug rod 12 is fixed.
[0031] A fixing rope 13 is fixedly connected to the outer surface of the moving plate 11. An auxiliary rod 19 is fixedly connected inside the second support plate 8. The outer surface of the fixing rope 13 is slidably connected with the outer surface of the auxiliary rod 19, and the outer surface of the fixing rope 13 is slidably connected with the inside of the second support plate 8. The auxiliary rod 19 mainly plays a role in guiding the fixing rope 13 to ensure the stability of the control of the plug rod 12 by the fixing rope 13.
[0032] The other end of the fixing rope 13 is fixedly connected with a limiting block 20, and the outer surface of the limiting block 20 is slidably connected with the outer surface of the second support plate 8. The position of one end of the fixing rope 13 can be limited through the limiting block 20, preventing one end of the fixing rope 13 from entering the inside of the second support plate 8 under the elastic force of the spring 18, and ensuring the stability of the fixing rope 13 during use.
[0033] Working principle: When in use, the backpack 1 can be reflected by the first reflective strip 2 and the second reflective strip 16. When it is necessary to compress the items inside the backpack 1, the first support plate 7 can be rotated to open it to both sides. At this time, pulling the fixing rope 13 can drive the moving plate 11 to move, and the insertion rod 12 can be controlled to move. At this time, the position of the second support plate 8 can be adjusted. After the adjustment is completed, under the action of the spring 18, the insertion rod 12 can be controlled to enter the fixing hole 17, and at this time, the position of the second support plate 8 is stably fixed.
