[0001] This utility model relates to the technical field of trolley cases, specifically to a protective structure for trolley cases. Background Technology

[0002] A rolling suitcase is a type of luggage equipped with a pull handle and wheels. It is widely used due to its convenience. Rolling suitcases are further categorized by the pull handle: single-tube and double-tube handles are available. The handle tubes also come in square and round shapes to facilitate dragging while walking, significantly reducing the burden. During use, rolling suitcases inevitably experience some bumps and knocks, and repeated impacts can easily cause deformation or damage to the entire suitcase.

[0003] Chinese patent CN222692890U discloses a trolley case with a collision protection structure. The trolley case includes a protective corner guard fixedly connected to each of its four outer corners. A sliding groove is provided between the protective corner guard and the trolley case for inserting a main protective plate, a first side protective plate, and a second side protective plate. There are four protective corner guards, each with a mounting hole at its apex for fixing a rotating shaft. Multiple bolt holes are also provided at the apex of each of the four protective corner guards. A baffle plate is movably sleeved on the outer side of the rotating shaft. The baffle plate has a V-shaped structure, and a bolt is fixedly and vertically installed at its apex, with the bolt matching the bolt hole.

[0004] In the above solution, by installing protective corners at the four corners of the outside of the suitcase, each protective plate can be inserted into the outside of the suitcase to protect it. However, this solution has the following drawbacks: when the suitcase is hit by an external force, the protective structure cannot effectively buffer and absorb the force, and the impact force is easily transmitted to the suitcase. Utility Model Content

[0005] The purpose of this invention is to provide a protective structure for a suitcase, in order to solve the problem that when a suitcase is subjected to an external impact, the protective structure cannot effectively buffer and absorb the force, and the impact force is easily transmitted to the suitcase.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a protective structure for a trolley case, comprising two protective frames, both of which are fixed to the bottom surface of the trolley case body. A shock-absorbing pad is fixed to the inner wall of each protective frame, and the shock-absorbing pad contacts the outer wall of the trolley case body. Several placement slots are provided at the end of the left protective frame, and a receiving groove is provided on the inner wall of each placement slot. A connecting post is inserted into the inner wall of the receiving groove, and a sealing ring is fixed to the outer wall of the connecting post, with the outer wall of the sealing ring contacting the inner wall of the receiving groove. Several limiting posts are fixed to the end of the right protective frame, and the limiting posts contact the connecting posts.

[0007] Preferably, the outer wall of the connecting column has two limiting grooves, the inner wall of the placement groove has two limiting blocks fixed, and the connecting column is slidably connected to the outside of the limiting blocks.

[0008] Preferably, the outer wall of the protective frame is fixed with several hooks.

[0009] Preferably, the protective frame has two L-shaped grooves, and the inner wall of the L-shaped groove is rotatably provided with an L-shaped bracket, and the bottom surface of the L-shaped bracket is fixed with a foot pad.

[0010] Preferably, a pull rod body is slidably connected to the top surface of the suitcase body, and an anti-slip sleeve is fixed to the outer wall of the pull rod body.

[0011] Preferably, the top surface of the protective frame on the right side is provided with a snap-fit ​​groove, and a cup holder is snapped into the inner wall of the snap-fit ​​groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the synergistic action of the protective frame, shock-absorbing pads, connecting columns, sealing rings, and limiting columns, an air cushion buffer structure is effectively formed, reducing the force transmitted to the suitcase body and effectively preventing damage to the protective frame and suitcase body due to external impacts, thus ensuring the integrity of the suitcase body and improving the protective efficiency of the protective structure. 2. Through the synergistic action of the limiting blocks and limiting grooves, the connecting columns are limited, allowing them to slide stably within the receiving groove, effectively preventing the connecting columns from detaching.

[0014] Second, the hooks allow for hanging items, saving labor costs and increasing the functionality of the suitcase. Besides hanging items, the hooks, fixed to the outer wall of the protective frame, provide auxiliary support when the suitcase is laid flat. The L-shaped bracket provides support for the suitcase when unfolded, enhancing its stability in an upright position and preventing it from tipping over upon impact, thus improving the practicality of the L-shaped bracket.

[0015] Third, the anti-slip sleeve increases the friction between the user's hand and the handle, making it more stable when pulling the suitcase and effectively preventing slippage. The cup holder attaches to the top of the protective frame via a snap-fit ​​groove, allowing users to place water cups, beverage bottles, or other cylindrical items for easy access and preventing tipping due to unstable handling or placement.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, a protective structure for a suitcase includes two protective frames 1, both of which are fixed to the bottom surface of the suitcase body 2. A shock-absorbing pad 3 is fixed to the inner wall of each protective frame 1, and the shock-absorbing pad 3 contacts the outer wall of the suitcase body 2. Several placement slots 4 are provided at the end of the left protective frame 1, and a receiving slot 5 is provided on the inner wall of each placement slot 4. A connecting post 6 is inserted into the inner wall of the receiving slot 5, and a sealing ring 7 is fixed to the outer wall of the connecting post 6, contacting the inner wall of the receiving slot 5. Several limiting posts 8 are fixed to the end of the right protective frame 1, and the limiting posts 8 contact the connecting post 6. Two limiting grooves 9 are provided on the outer wall of the connecting post 6, and two limiting blocks 10 are fixed to the inner wall of the placement slot 4. The connecting post 6 is slidably connected to the outside of the limiting blocks 10.

[0023] During use, when the protective frame 1 and the suitcase body 2 are impacted by external forces, the limiting post 8 on the right side of the protective frame 1 will squeeze the connecting post 6 to produce axial relative displacement. Under the action of pressure, the connecting post 6 will drive the sealing ring 7 to move into the receiving groove 5. At this time, the connecting post 6 and the sealing ring 7 will squeeze the air in the receiving groove 5, thereby forming an air cushion in the receiving groove 5, forming a damping effect, absorbing the impact energy. The shock-absorbing pad 3 will reduce the force transmitted from the protective frame 1 to the suitcase body 2, effectively reducing the risk of damage to the suitcase body 2 and the internal items due to bumps or impacts. The relative movement of the connecting post 6 and the limiting post 8 can disperse local pressure and avoid a single component bearing excessive external force.

[0024] Through the coordinated action of the protective frame 1, shock-absorbing pad 3, connecting column 6, sealing ring 7, and limiting column 8, an air cushion buffer structure is effectively formed, reducing the force transmitted to the suitcase body 2. This effectively prevents damage to the protective frame 1 and suitcase body 2 due to external impacts, ensuring the integrity of the suitcase body 2 and thus improving the protective efficiency of the structure. Through the coordinated action of the limiting block 10 and the limiting groove 9, the connecting column 6 is limited, allowing it to slide stably within the receiving groove 5, effectively preventing it from detaching.

[0025] like Figures 1-4 As shown, the outer wall of the protective frame 1 is fixed with several hooks 11, and the protective frame 1 has two L-shaped grooves 12. The inner wall of the L-shaped groove 12 is rotatably provided with an L-shaped bracket 13. The bottom surface of the L-shaped bracket 13 is fixed with a foot pad. The top surface of the trolley case body 2 is slidably connected with a pull rod body 14. The outer wall of the pull rod body 14 is fixed with an anti-slip sleeve 15. The top surface of the protective frame 1 on the right side is provided with a snap-fit ​​groove 16. The inner wall of the snap-fit ​​groove 16 is snapped with a cup holder 17.

[0026] In use, items can be hung using hooks 11, saving labor costs and increasing the functionality of the suitcase body 2. Besides hanging items, hooks 11, fixed to the outer wall of the protective frame 1, provide auxiliary support when the suitcase body 2 is laid flat. The L-shaped bracket 13 provides support for the suitcase body 2 when unfolded, enhancing its stability in an upright state and preventing it from tipping over when impacted by external forces, thus improving the practicality of the L-shaped bracket 13. The anti-slip sleeve 15 increases the friction between the user's hand and the handle 14, making it more stable when pulling the suitcase body 2 and effectively preventing slippage. The cup holder 17 is attached to the top surface of the protective frame 1 via a snap-fit ​​groove 16, allowing for the placement of water cups, beverage bottles, or other cylindrical items, facilitating easy access to drinks and preventing tipping due to unstable handling or placement.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
