Description

Technical Field

[0001] This utility model relates to the technical field of trolley cases, specifically to an anti-tipping trolley case. Background Technology

[0002] A rolling suitcase is a type of luggage equipped with a pull handle and wheels, widely used for its convenience. Rolling suitcases are further categorized by their pull handle: single-tube and double-tube handles, and the tubes of the handle can be square or round, making them easier to drag while walking and significantly reducing the burden. Rolling suitcases can be carried by hand or pulled. Anti-tipping rolling suitcases are a unique type of luggage designed to reduce the likelihood of tipping over on uneven ground or when the center of gravity is unstable.

[0003] Chinese patent CN212117363U discloses an anti-tipping suitcase, comprising a suitcase body, a pull rod, and an anti-tipping device. The pull rod is located on the back of the suitcase body, and the anti-tipping device is located on the bottom of the suitcase body. The anti-tipping device includes two support plates, which are respectively located on both sides of the suitcase body. The support plates are rotatably connected to the side wall of the suitcase body, and several elastic elements are connected between the two support plates.

[0004] In the above solution, by setting an anti-tipping device, when the case tilts to one side, the bottom of the support plate contacts the ground to support the case and prevent it from tilting further. However, this solution has the following disadvantages: Since the two support plates are movably connected to the case and are connected by elastic elements, the support plates are prone to shifting under stress, which makes the suitcase prone to tipping over when it is hit by external forces. Utility Model Content

[0005] The purpose of this invention is to provide an anti-tipping suitcase to solve the problem that the two support plates are movably connected to the suitcase body and are connected by elastic elements, which makes the support plates prone to displacement under force, causing the suitcase to easily tip over when subjected to external impact.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an anti-tipping trolley case, comprising two receiving slots, the two receiving slots being respectively opened on two bottom plates of the trolley case body, a limiting post fixed to the inner wall of the receiving slot, a limiting block fixed to the outer wall of the limiting post, an L-shaped plate slidably connected to the inner wall of the receiving slot, a limiting groove opened on the L-shaped plate, the limiting post being inserted into the limiting groove, a limiting hole opened on the top surface of the L-shaped plate, the limiting hole communicating with the limiting groove, the limiting block being slidably connected to the limiting hole, two tension springs fixed on the L-shaped plate, the other end of the tension springs being fixed to the inner wall of the receiving slot, a plurality of mounting slots opened on the bottom surface of the L-shaped plate, and rollers rotatably provided on the inner wall of the mounting slots.

[0007] Preferably, the top surface of the L-shaped plate is provided with several snap-fit ​​grooves, and two snap-fit ​​blocks are rotatably provided on the bottom plate of the trolley case body, the snap-fit ​​blocks snapping into the snap-fit ​​grooves.

[0008] Preferably, the top surface of the L-shaped plate is provided with a plurality of fixing grooves, and the inner wall of the fixing grooves is fixed with an anti-slip pad.

[0009] Preferably, two support columns are fixed on the left bottom plate of the suitcase body, and two support grooves are opened on the right bottom plate of the suitcase body, with the support columns being engaged in the support grooves.

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

[0011] Preferably, the outer wall of the suitcase body is fixed with several anti-collision strips.

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

[0013] 1. The combination of limiting posts, limiting blocks, L-shaped plates, and rollers increases the support area of ​​the bottom plate of the suitcase, making the suitcase more stable when placed upright. This effectively prevents the suitcase from tipping over when subjected to external impacts, ensuring the integrity of the suitcase and improving its usability. 2. The combination of locking blocks and locking slots limits and fixes the L-shaped plate, providing stable support for the suitcase and preventing it from retracting under impact, thus ensuring the stability of the L-shaped plate support.

[0014] 2. When the L-shaped panel is unfolded to serve as a temporary tabletop (for placing small items such as mobile phones and wallets), the anti-slip mat increases the friction between the items and the top surface of the L-shaped panel, effectively preventing items from slipping due to bumps or tilting. When the suitcase body is closed, the snap-fit ​​design between the support column and the support groove forms a rigid connection, which can distribute the weight of the items inside the suitcase body, effectively preventing misalignment on the left and right sides of the suitcase body, thereby increasing the stability of the bottom plate connection.

[0015] Third, the anti-slip sleeve increases the friction between the user's hand and the handle, making the grip more secure and effectively preventing slippage when pulling the handle, thus improving its practicality. The anti-collision strips protect the four corners of the suitcase, absorbing the impact force from collisions and effectively preventing wear or cracking at the corners caused by external forces.

Detailed Implementation

[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, an anti-tipping trolley case includes two receiving slots 1, which are respectively opened on the two bottom plates of the trolley case body 2. The inner wall of the receiving slot 1 is fixed with a limit post 3, and the outer wall of the limit post 3 is fixed with a limit block 4. An L-shaped plate 5 is slidably connected to the inner wall of the receiving slot 1. A limit groove 6 is opened on the L-shaped plate 5, and the limit post 3 is inserted into the limit groove 6. A limit hole 7 is opened on the top surface of the L-shaped plate 5, and the limit hole 7 is connected to the limit groove 6. The limit block 4 is slidably connected to the limit hole 7. Two tension springs 8 are fixed on the L-shaped plate 5, and the other end of the tension spring 8 is fixed to the inner wall of the receiving slot 1. Several mounting slots 9 are opened on the bottom surface of the L-shaped plate 5, and rollers 10 are rotatably provided on the inner wall of the mounting slots 9. Several snap-fit ​​slots 11 are opened on the top surface of the L-shaped plate 5. Two snap-fit ​​blocks 12 are rotatably provided on the bottom plate of the trolley case body 2, and the snap-fit ​​blocks 12 are snapped into the snap-fit ​​slots 11.

[0023] In use, when the L-shaped plate 5 needs to be unfolded, the user can first rotate the double-sided locking blocks 12 to disengage them from the locking grooves 11, releasing the axial constraint on the L-shaped plate 5. Then, force is applied to the L-shaped plate 5, driving it to slide along the outer walls of the limiting post 3 and the limiting block 4, causing the L-shaped plate 5 to move axially towards both sides of the trolley case body 2. Simultaneously, the tension spring 8 is elastically extended until the roller 10 contacts the ground to form a support point. When the L-shaped plate 5 moves to the appropriate position, the locking blocks 12 can be rotated again to embed it into the locking grooves 11, achieving rigid positioning of the L-shaped plate 5. At this time, the extended L-shaped plate 5 lowers the center of gravity by increasing the support area, optimizing the force distribution of the bottom plate, and significantly improving resistance. The overturning stability (especially under lateral impact conditions) prevents the suitcase body 2 from tipping over when subjected to external force. At the same time, the top surface of the extended L-shaped plate 5 can serve as a temporary storage platform, which is convenient for users to place small items. Its anti-slip pads 14 layers can ensure the static stability of small items. If the L-shaped plate 5 needs to be stored, the locking block 12 can be rotated again to disengage from the locking groove 11 and release the mechanical constraint. At this time, the tension spring 8 will restore its elastic potential energy and drive the L-shaped plate 5 to retract axially along the limiting post 3 into the receiving groove 1. After resetting, the locking block 12 is tightened into the locking groove 11 to avoid unexpected displacement of the L-shaped plate 5 and ensure compactness during movement.

[0024] The combination of limiting post 3, limiting block 4, L-shaped plate 5, and roller 10 increases the support area of ​​the bottom plate of the suitcase body 2, making the suitcase body 2 more stable when placed upright. This effectively prevents the suitcase body 2 from tipping over when subjected to external impact, ensuring the integrity of the suitcase body 2 and improving its usability. The combination of locking block 12 and locking groove 11 limits and fixes the L-shaped plate 5, providing stable support for the suitcase body 2 and effectively preventing it from retracting when subjected to external impact, thus ensuring the stability of the L-shaped plate's support.

[0025] like Figures 1-4 As shown, the top surface of the L-shaped plate 5 has several fixing grooves 13, and the inner wall of the fixing grooves 13 is fixed with anti-slip pads 14. Two support columns 15 are fixed on the left bottom plate of the suitcase body 2, and two support grooves 16 are opened on the right bottom plate of the suitcase body 2. The support columns 15 are snapped into the support grooves 16. The top surface of the suitcase body 2 is slidably provided with a pull rod body 17. The outer wall of the handle of the pull rod body 17 is fixed with an anti-slip sleeve 18, and several anti-collision strips 19 are fixed on the outer wall of the suitcase body 2.

[0026] During use, when the L-shaped panel 5 is unfolded as a temporary table (such as for placing small items like mobile phones and wallets), the anti-slip mat 14 increases the friction between the items and the top surface of the L-shaped panel 5, effectively preventing items from slipping due to bumps or tilting. When the suitcase body 2 is closed, the snap-fit ​​connection between the support column 15 and the support groove 16 forms a rigid connection, which can distribute the weight of the items inside the suitcase body 2, effectively preventing misalignment on the left and right sides of the suitcase body 2, thereby increasing the stability of the bottom plate connection. The anti-slip sleeve 18 increases the friction between the user's hand and the handle body 17, making the user's grip on the handle body 17 more secure, effectively preventing slippage when pulling the handle body 17, thus improving the practicality of the anti-slip sleeve 18. The anti-collision strip 19 protects the four corners of the suitcase body 2, absorbing the impact force generated when the four corners of the suitcase body 2 collide, effectively preventing the corners of the suitcase body 2 from being worn or cracked due to external impacts.

[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.
