Description

Technical Field

[0001] The utility model relates to the technical field of bag manufacturing, and more specifically, to a double-layer trolley case. Background Art

[0002] In order to prevent the objects that are not fully loaded in the suitcase from shifting, most suitcases are equipped with elastic straps with buckles inside, which can be used to tighten the objects in the suitcase. However, this is not very effective for small objects, and when the suitcase is subjected to a large impact, the objects are still easy to break free from the gaps in the straps, causing the objects to be scattered in the suitcase, resulting in poor overall effect. Based on this, the utility model proposes a double-layer suitcase. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a double-layer trolley case.

[0004] In order to solve the above technical problems, the purpose of the utility model is achieved as follows: the utility model involves a double-layer trolley case, including a trolley case body, the trolley case body has an end face outer panel, the inner side of the end face outer panel is provided with an end face inner panel arranged inside the trolley case body, a telescopic tube is connected between the end face inner panel and the end face outer panel, a sealed chamber is formed between the telescopic tube and the end face inner panel and the end face outer panel, and an air nozzle is provided on the end face inner panel or the end face outer panel.

[0005] The utility model is further configured as follows: the air nozzle is arranged on the end surface outer plate.

[0006] The utility model is further configured as follows: a sink groove in which the air supply nozzle is buried is provided on the end surface outer plate.

[0007] In summary, the utility model has the following beneficial effects: the double-layer trolley case involved in the utility model, by using an air nozzle to pressurize the sealed chamber, until the inner plate of the end face moves away from the outer plate of the end face, until the inner plate of the end face presses the objects stored in the trolley case, and then the air nozzle is closed, so that when the trolley case is impacted, the objects in the box will not be shifted, which plays a role of limiting and preventing scattering, and the overall function is complete and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a schematic diagram of the overall structure of the utility model. DETAILED DESCRIPTION

[0009] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0010] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0011] Example 1

[0012] See also Figure 1 As shown, a double-layer trolley case involved in this embodiment includes a trolley case body 100, and the trolley case body 100 has an end face outer panel 1, and the inner side of the end face outer panel 1 is provided with an end face inner panel 2 arranged inside the trolley case body 100, and a telescopic tube 3 is connected between the end face inner panel 2 and the end face outer panel 1, and a sealed chamber 4 is formed between the telescopic tube 3 and the end face inner panel 2 and the end face outer panel 1, and an air nozzle 5 is provided on the end face outer panel 1.

[0013] In this embodiment, when placing objects in the suitcase, the sealed chamber 4 is not pressurized, the telescopic tube 3 is in a shortened state, and the end inner plate 2 is close to the end outer plate 1. After the objects are placed in the box (as flat as possible), the suitcase is closed, the air nozzle 5 is opened, and the sealed chamber 4 is pressurized using an air injection device. During this period, the telescopic tube 3 gradually extends and the end inner plate 2 moves away from the end outer plate 1 until the end inner plate 2 is pressed against the object. The pressurization is stopped, and the air injection device is removed and the air nozzle 5 is closed.

[0014] Among them, in order to facilitate the observation of the object contacted by the end surface inner plate 2, a window can be set on the side or end surface of the trolley case body 100; if not set, the pressurization situation can also be judged by the pressure feedback device on the gas injection equipment. If the pressurization is blocked or the pressurization speed slows down or stops, it means that the end surface inner plate 2 contacts and presses the object.

[0015] The end face inner plate 2 is made of soft rubber material, which can adapt to the surface formed by the uneven objects in contact with it and enhance the pressing effect.

[0016] Example 2

[0017] See also Figure 1 As shown, the double-layer trolley case involved in this embodiment is further configured on the basis of Embodiment 1, wherein a sink (not shown) in which the air supply nozzle is buried is provided on the end outer panel 1.

[0018] In this embodiment, the gas nozzle 5 can be buried in the sink groove to protect and prevent collision.

[0019] The double-layer trolley case involved in the utility model increases pressure on the sealed chamber by using an air nozzle so that the inner plate of the end face moves away from the outer plate of the end face until the inner plate of the end face presses the objects stored in the trolley case. Then, the air nozzle is closed so that when the trolley case is impacted, the objects in the case will not be shifted, thereby playing a role of limiting and preventing scattering. The overall function is perfect and the practicability is strong.

[0020] Unless otherwise specified, in the present invention, the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicating orientation or positional relationship are based on the orientation or positional relationship actually shown, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the terms describing the orientation or positional relationship in the present invention are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood in combination with the embodiments and according to specific circumstances.
