Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0021] Please see Figure 1-5 This utility model provides a high-performance trolley case, including a case lid 1 and a case body 2, which are hinged together. A storage box 3 is slidably connected inside the case lid 1. A T-shaped block 7 is symmetrically fixedly installed on the top surface of the storage box 3. A first T-shaped groove 8 and a second T-shaped groove 9 are symmetrically arranged on the top surfaces of the case lid 1 and the case body 2, respectively. The first T-shaped groove 8 and the second T-shaped groove 9 in the connected case lid 1 and case body 2 are interconnected. One end of the T-shaped block 7 is slidably connected to the inside of the first T-shaped groove 8. A cover plate 10 is hingedly installed on the top surface of the storage box 3. The top surface of the cover plate 10 is connected to the storage box 3. The top surface of the placement box 3 is horizontal, and the other end is slidably connected to the inside of the second T-shaped groove 9. A handle 5 is fixedly installed on the left side wall of the placement box 3. When using the box body 2, first pull the placement box 3 out from the inside of the box cover 1 through the handle 5, open the cover plate 10, place small items inside the placement box 3, then reset the placement box 3, and then place clothes and other items inside the box body 2. Then close the box body 2, so that the box body 2 is connected to the box cover 1. When taking out the placed small items, simply pull out the placement box 3 to take out the items inside. Example 2

[0022] To ensure stable placement of the placement box 3, in this embodiment, as follows: Figure 3-5As shown, the top surface of the box 3 has a first limiting hole 11 and a second limiting hole 15 respectively on both sides. A fixing tube 6 is fixedly installed on the top surface of the box cover 1. A lifting rod 12 is placed on the top of the fixing tube 6. A fixing block 4 is slidably connected inside the fixing tube 6. A limiting rod 14 is provided inside the fixing tube 6. The upper end of the limiting rod 14 passes through the top surface of the fixing tube 6 and is fixedly connected to the bottom of the lifting rod 12. The upper end of the limiting rod 14 is slidably connected to the top surface of the fixing tube 6. The lower end of the limiting rod 14 passes through the top surface of the box cover 1 to the inside of the box cover 1. The limiting rod 14 is slidably connected inside the first limiting hole 11. The fixing block 4 is fixedly sleeved on the rod wall of the limiting rod 14. The first limiting hole 11 The diameter of the first limiting hole 11 is equal to that of the second limiting hole 15, and the diameter of the limiting rod 14 matches that of the first limiting hole 11. A tension spring 13 is fixedly installed between the fixing block 4 and the top surface inside the fixing tube 6. The tension spring 13 is sleeved on the outside of the limiting rod 14. When the placement box 3 is reset, pulling the pull rod 12 upwards can move the limiting rod 14 upwards until the first limiting hole 11 on the placement box 3 moves to below the pull rod 12, so that the pull rod 12 slides and connects to the inside of the first limiting hole 11, which can conveniently limit the position of the placement box 3. At the same time, it is connected to the inside of the second limiting hole 15, which can conveniently fix the position of the placement box 3 when it is outside the box cover 1.

[0023] It should be noted that in this embodiment, when using a high-performance rolling suitcase, such as Figure 1-5 As shown, when using the box 2, firstly, pull the storage box 3 out from inside the lid 1 using the handle 5, open the cover 10, place small items inside the storage box 3, then reset the storage box 3, and then place clothes and other items inside the box 2. Then close the box 2, connecting the box 2 to the lid 1. When taking out small items, simply pull out the storage box 3 to retrieve the items inside. When the storage box 3 resets, pull the lever 12 upwards, which moves the limiting lever 14 upwards until the first limiting hole 11 on the storage box 3 moves below the lever 12, allowing the lever 12 to slide into the first limiting hole 11, conveniently limiting the position of the storage box 3. At the same time, it connects to the second limiting hole 15, conveniently fixing the position of the storage box 3 when it is outside the lid 1. Furthermore, after pulling out the storage box 3, it can not only be used as a supporting table, but also increase the internal space of the box 2.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
