Description

Technical Field

[0001] This utility model relates to the field of trolley case technology, specifically a trolley case with a folding chair structure. Background Technology

[0002] A rolling suitcase is a travel suitcase that is easy to push and pull. It is usually equipped with a retractable handle, wheels and multi-purpose compartment design. It is made of hard material or soft fabric and used to protect the items. It is suitable for short or long trips, business trips and other scenarios.

[0003] In the existing technology, folding chairs are inconvenient to store and the overall operation is relatively cumbersome, making them inconvenient for users to operate.

[0004] To overcome the aforementioned shortcomings, a Chinese patent (publication number CN211431362U) discloses a trolley case with a folding chair, comprising a case body and a telescopic rod fixed to the case body. The telescopic rod includes two telescopic bars and a handle fixed to the end of the telescopic bar away from the case body. A storage slot is provided between the two telescopic bars, and a folding stool is installed in the storage slot, hinged to the top of the case body. A support is provided between the folding stool and the case body. An auxiliary support is provided at the end of the storage slot away from the folding stool, extending out of the case body and abutting the ground or other placement surface. This design addresses the problem that existing trolley cases with folding chairs have a low folding chair height and occupy a large amount of internal storage space, while offering a higher stool height and smaller space occupation within the case.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, after unfolding, the folding chair of the suitcase is inconvenient to retract. Also, for heavier people, the folding chair of the suitcase does not provide good support and has poor load-bearing capacity, which can easily affect the use of a large number of people. Utility Model Content

[0006] The purpose of this utility model is to provide a trolley case with a folding chair structure to solve the problems mentioned in the background art, such as the inconvenience of retracting the folding chair after unfolding, and the poor support and load-bearing capacity of the folding chair for heavier people, which can easily affect the use of a large number of people.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a trolley case with a folding chair structure, comprising a case body and a folding plate rotatably mounted at the rear end of the case body. The bottom of the folding plate is provided with a storage compartment, and the storage compartment is provided with a convenient folding mechanism. The convenient folding mechanism can portablely store the folding plate. A sliding rod is rotatably mounted at the bottom of the folding plate, and an auxiliary support structure is provided at the end of the sliding rod. The auxiliary support structure improves the support force of the folding plate.

[0008] Furthermore, a locking block is installed at the rear end of the box, and the locking block is slidably connected inside the box. The locking block is T-shaped, and the bottom of the locking block is inclined.

[0009] Furthermore, a lever is fixedly installed on the outer side of the card block, and the outer side of the lever passes through the housing. A pressure spring is provided between the upper end of the card block and the inner wall of the housing.

[0010] Furthermore, the convenient folding mechanism is provided with a base plate, which is rotatably installed with the storage compartment, and the lower end of the base plate is T-shaped.

[0011] Furthermore, positioning boxes are fixedly installed on both sides of the storage compartment, and positioning springs are installed inside the positioning boxes. Abutment blocks are installed at the ends of the positioning springs, and the abutment blocks abut against the bottom plate.

[0012] Furthermore, the auxiliary support structure is provided with a sliding rod, the end of which is rotatably mounted to the bottom of the folding plate, and a sleeve is fitted on the right side surface of the sliding rod, the end of which is rotatably mounted to the bottom of the base plate.

[0013] Furthermore, the sleeve is provided with a first airbag inside, and a corrugated air guide tube is connected to the side of the first airbag. The end of the corrugated air guide tube is connected to a second airbag, and the second airbag is attached to the side of the bottom plate. The first airbag and the slide rod form a pressing structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. After the folding panel is opened, the bottom plate inside the storage compartment can be rotated and unfolded to form a support. The height of the unfolded bottom plate is level with the tires at the bottom of the box, thus providing effective support for the folding panel. When the bottom plate needs to be stored, the abutment block is pushed into the positioning box. The positioning spring applies elastic force to press the abutment block against the bottom plate, thereby locking and securing the bottom plate to prevent it from easily coming off. Furthermore, when the folding panel needs to be stored, the panel is pushed to press the locking block. Since the bottom of the locking block is inclined, it can be pushed into the groove at the rear of the box after being pressed until the folding panel completely passes the locking block. Then, the locking block is reset under the action of the pressure spring, locking the folding panel in place, thus achieving convenient storage.

[0015] 2. As the base plate rotates and unfolds within the storage compartment, a support structure is formed through the fitting of the sliding rod and the sleeve, providing triangular support between the folding plate and the base plate, thereby enhancing the load-bearing capacity of the folding plate and enabling it to meet the usage needs of a large number of people. Furthermore, when the base plate is stored, the sliding rod is embedded inside the sleeve for storage. At this time, the sliding rod squeezes the first air bladder inside the sleeve. After being squeezed, the first air bladder delivers the internal air to the second air bladder through the corrugated air guide tube, causing the second air bladder to expand. The expanded second air bladder presses against the base plate in the storage compartment, thereby further improving the stability of the base plate in the stored state and preventing it from shaking.

[0024] 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.

[0025] Example 1: As Figures 1-5The technical solution shown is a trolley case with a folding chair structure. To solve the problem of inconvenient folding, it discloses: a case body 1 and a folding plate 2 rotatably mounted at the rear end of the case body 1. The bottom of the folding plate 2 is provided with a storage compartment 6, and the storage compartment 6 is provided with a convenient folding mechanism, which can conveniently store the folding plate 2. A locking block 3 is installed at the rear end of the case body 1, and the locking block 3 is slidably connected to the inside of the case body 1. The locking block 3 is T-shaped, and the bottom of the locking block 3 is tilted. The obliquely set, the outer side of the locking block 3 is fixedly installed with a lever 5, and the outer side of the lever 5 passes through the box body 1. A pressure spring 4 is set between the upper end of the locking block 3 and the inner wall of the box body 1. The convenient folding mechanism is provided with a bottom plate 7, and the bottom plate 7 is rotatably installed with the storage compartment 6. The lower end of the bottom plate 7 is shaped like a "T". Positioning boxes 8 are fixedly installed on both sides of the storage compartment 6. Positioning springs 9 are installed inside the positioning boxes 8. Abutting blocks 10 are installed at the ends of the positioning springs 9, and the abutting blocks 10 abut against the bottom plate 7.

[0026] In use, by moving the lever 5 at the rear end of the housing 1, the lever 5 moves the locking block 3 upward, thereby pressing the pressure spring 4, causing the folding plate 2 at the rear end of the housing 1 to disengage, and the folding plate 2 can then be opened. Conversely, when the folding plate 2 needs to be folded, by pushing the folding plate 2, the locking block 3 is pressed. Because the bottom of the locking block 3 is inclined, it can be pressed into the groove at the rear end of the housing 1 until the folding plate 2 passes the locking block 3. Under the action of the pressure spring 4, the locking block 3 locks the folding plate 2, thus facilitating folding and storage. Also, after the folding plate 2 is opened, it can be... The bottom plate 7 inside the storage compartment 6 is rotated by moving it, and the bottom plate 7 opens to form a support. The height of the bottom plate 7 is level with the bottom tire of the box 1, which can support the folding plate 2. When the bottom plate 7 needs to be stored, it is rotated and folded into the storage compartment 6 by moving it. The bottom plate 7 inside the storage compartment 6 first presses against the abutment block 10, pushing the abutment block 10 into the positioning box 8. The abutment block 10 is pressed by the elastic force of the positioning spring 9, which can lock and engage the bottom plate 7, fix the bottom plate 7 and prevent it from easily coming off.

[0027] Example 2: Figures 1-7The technical solution shown, based on Embodiment 1, discloses the following to address the problem of poor support effect: a sliding rod 11 is rotatably mounted on the bottom of the folding plate 2, and an auxiliary support structure is provided at the end of the sliding rod 11. The auxiliary support structure improves the support force of the folding plate 2. The auxiliary support structure is provided with the sliding rod 11, and the end of the sliding rod 11 is rotatably mounted to the bottom of the folding plate 2. A sleeve 12 is sleeved on the right side surface of the sliding rod 11, and the end of the sleeve 12 is rotatably mounted to the bottom of the base plate 7. A first airbag 13 is provided inside the sleeve 12, and a corrugated air guide pipe 14 is connected to the side of the first airbag 13. A second airbag 15 is connected to the end of the corrugated air guide pipe 14, and the second airbag 15 is correspondingly attached to the side of the base plate 7. The first airbag 13 and the sliding rod 11 form a pressing structure.

[0028] As the base plate 7 rotates and unfolds inside the storage compartment 6, a support structure is formed by the sliding rod 11 and the sleeve 12, providing triangular support between the folding plate 2 and the base plate 7. This improves the support effect of the folding plate 2 and can accommodate a large number of people. At the same time, when the base plate 7 is stored, the sliding rod 11 is embedded inside the sleeve 12. At this time, the sliding rod 11 compresses the first airbag 13 inside the sleeve 12. The first airbag 13 is compressed and the internal air is transported into the second airbag 15 through the corrugated air duct 14. The air entering the second airbag 15 can cause the second airbag 15 to expand, so that the second airbag 15 abuts against the base plate 7 inside the storage compartment 6, further improving the stability of the base plate 7 and preventing it from shaking during storage.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
