[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] It should be noted that all components in the technical solution of this application require necessary additional facilities for water supply, oil supply, power supply, and gas supply for driving and / or control. Unless otherwise stated, they are assumed to be used and equipped with existing technology and no special explanation is required.

[0023] It should be noted that, in order to make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Depend on Figure 1-4 The illustrated convenient trolley case includes a first case body 1 and a second case body 2. One side of the first case body 1 and one side of the second case body 2 are attached to each other and hinged together. Both the first case body 1 and the second case body 2 are telescopic. Mounting holes are respectively opened on the opposite sides of the first case body 1 and the second case body 2. Telescopic rods are fixedly installed in the mounting holes. The telescopic rods are driven by a drive assembly. The drive assembly has two sets respectively set in the inner cavity of the first case body 1 and the inner cavity of the second case body 2. The first case body 1 can be folded 180° relative to the second case body 2.

[0025] Further optimizing the design, the first compartment 1 includes a fixed box 3, which is a hollow cubic structure with an open top and one side. The fixed box 3 provides support for the items placed inside the suitcase. A flexible partition 4 is fixedly connected to the side of the fixed box 3, and a lid 5 is fixedly connected to the top of the partition 4. A zipper is detachably connected between the lid 5 and the fixed box 3. The partition 4 can gradually rise as more items are added to the fixed box 3, thus expanding the volume of the suitcase. The detachable connection between the lid 5 and the fixed box 3 also allows the first compartment 1 to be easily stored without needing to expand its capacity. Furthermore, the zipper, which uses continuously arranged teeth to connect or separate items, is widely used in clothing, bags, tents, etc., and is existing technology, so it will not be described in detail here. A curtain 6 is detachably connected to the open side of the first compartment 1 and the open side of the partition 4. Furthermore, the side of the curtain 6 is detachably connected to the partition 4 via a zipper, facilitating the opening and closing of the curtain 6. The partition curtain 6 is detachably connected to the bottom surface of the inner cavity of the first box 1. The partition curtain 6 can realize the connection and separation of the space between the first box 1 and the second box 2, and can also effectively protect the items when folded.

[0026] Furthermore, the sides of the enclosure 4 have openings that can be closed with zippers, allowing the suitcase to be filled using multiple inlets or...

[0027] Further optimizing the design, a groove 7 is formed on the bottom surface of the inner cavity of the first housing 1, and a pressure plate 8 is set above the groove 7. The pressure plate 8 is fixedly connected to the side of the first housing 1. The pressure plate 8 can press down on the curtain 6 when the curtain 6 and the connecting strap 15 pass through the gap, preventing the curtain 6 from being opened from the outside. Gap is provided in the groove 7 on both sides of the pressure plate 8. The bottom end of the curtain 6 passes through two gaps and is detachably connected to the bottom surface of the inner cavity of the first housing 1. Several Velcro straps (not shown in the attached figure) are fixedly connected to the bottom surface of the inner cavity of the first housing 1, and several connecting straps 15 are fixedly connected to the bottom end of the curtain 6. The connecting straps 15 are fixedly connected to the Velcro straps.

[0028] Furthermore, hook and loop fasteners, also known as Velcro or snap fasteners, are a common connecting accessory used in clothing. They are a type of existing technology and will not be described in detail here.

[0029] The design is further optimized so that the telescopic rod includes a rod body 9 and several sealing rings 10. The sealing rings 10 are sleeved and fixedly connected to the outside of the rod body 9. An air cylinder 11 is slidably connected to the outer side of the sealing ring 10. The air cylinder 11 is fixedly connected to the mounting hole. The drive component passes through the mounting hole and communicates with the air cylinder 11. The sealing ring 10 can form a sealed cavity between one end of the air cylinder 11 and the sealing ring 10. By injecting air into this cavity, the rod body 9 is pushed to move toward the other end of the air cylinder 11 and then enters the air cylinder 11 in the second housing 2, thus realizing the connection between the first housing 1 and the second housing 2.

[0030] The scheme is further optimized. The drive component includes two one-way valves 12, an airbag 13 and an air tube 14. The two ends of the air tube 14 are connected to two air cylinders 11 respectively. The air tube 14 and the airbag 13 are connected in series. The airbag 13 is fixedly connected to and connected to the one-way valves 12. The one-way valve 12 can allow air to enter the airbag 13 from the outside and then flow to the air cylinder 11 through the air tube 14 by the compression of the airbag 13. The airbag 13 is also equipped with a main valve to control whether the airbag 13 is sealed.

[0031] Further optimization of the scheme resulted in the second box 2 having the same structure as the first box 1.

[0032] Furthermore, when the first box 1 and the second box 2 are in a folded state, one side of the second box 2 and one side of the first box 1 are fixedly connected by Velcro, which facilitates the placement of the first box 1 and the second box 2.

[0033] The working process of this embodiment is as follows:

[0034] When the first box 1 and the second box 2 are filled with clothing, if there are not many items, the zipper between the lid 5 and the fixing box 3 will not be opened. This can reduce the size of the first box 1 or the second box 2, improve the compactness of the space, and facilitate the fixing of the items.

[0035] When there are many items, opening the zipper between the lid 5 and the fixed box 3 allows the lid 5 to be pulled up to a certain height, expanding the space of the first box 1 and the second box 2. Furthermore, to connect the first box 1 and the second box 2 together for easy pulling, the airbag 13 is squeezed by hand. The airbag 13 allows external air to enter through the one-way valve 12 and is pushed into the air tube 14 and air cylinder 11 during the squeezing process. The air pushes the rod 9 towards the other air cylinder 11 until it is pushed in. The rod 9 and the sealing ring 10 secure the two air cylinders 11, thus securing both the first box 1 and the second box 2.

[0036] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
