Description

Technical Field

[0001] This utility model relates to the field of luggage stand technology, and more specifically, to a stand structure for wheeled luggage. Background Technology

[0002] In the current technology, wheeled suitcases are widely recognized for their convenience as a common travel tool. However, when users use wheeled suitcases on slopes or other inclined surfaces, existing technologies have significant drawbacks.

[0003] Currently, traditional wheeled suitcases on the market are prone to tipping over when tilted due to the lack of an effective automatic adjustment and stabilizing support mechanism. Specifically, when a user is pulling a suitcase on a slope, the suitcase will tilt due to gravity, requiring the user to continuously hold the suitcase to prevent it from tipping over. This not only increases the user's workload and reduces the user experience, but also makes it impossible to effectively support the suitcase in some situations, such as when the user is carrying other items with both hands, leading to the suitcase tipping over, potentially damaging the contents, or even causing a safety accident.

[0004] Furthermore, while some existing suitcases attempt to address tipping issues by adding simple support structures, these structures often lack automatic adjustment. For example, some standing legs are fixed and cannot adaptively adjust to the suitcase's tilt, making it difficult to ensure stable support on complex terrains such as slopes. Other standing legs, while manually adjustable, are cumbersome to operate, requiring users to spend extra time and effort to adjust them, failing to meet the need for quick and convenient use. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This utility model is further configured as follows: it includes a box body, a pair of pulley bodies disposed at the bottom of the box body, and the foot structure further includes a fixed foot slidably disposed at the bottom of the box body and located next to the pair of pulley bodies, and an adjustment mechanism for adjusting the position of the fixed foot; the adjustment mechanism is disposed on the side of the box body, and the adjustment mechanism includes a lifting part, a first abutting part and a second abutting part; the lifting part is slidably disposed on the side of the box body, and the bottom of the lifting part is connected to the top of the fixed foot by fasteners; the first abutting part is slidably disposed on the side of the lifting part, and a plurality of abutting grooves for the second abutting part to abut on the side of the first abutting part; the second abutting part is horizontally slidably disposed on the side of the box body, and the second abutting part is a toothed structure that can abut with the abutting grooves. When the lifting part drives the first abutting part to slide downward, the abutting grooves on the side of the first abutting part can drive the second abutting part to slide away from the first abutting part. When the first abutting part stops sliding, the second abutting part can abut with the abutting grooves on the side of the first abutting part.

[0008] By adopting the above technical solution, the problem of needing continuous support from the user to prevent the box from tipping over when it is tilted is solved. The box can automatically adjust to a relatively parallel state in tilted scenarios such as slopes, and the feet and wheels provide stable support together.

[0012] The present invention is further configured such that: the adjusting mechanism includes a mounting part, a circular column, and a second return spring; the mounting part is disposed inside the housing; there are multiple circular columns respectively disposed on the side of the mounting part, and the second abutting part is clearance-fitted with the circular column, and a mounting chamber for mounting the circular column is provided on the side of the mounting part; the second return spring is disposed on the side of the mounting part, one end of the second return spring is fixed to the mounting part, and the other end of the second return spring is fixed to the second abutting part, and when the second abutting part slides toward the mounting part, the second return spring is in a compressed state.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0031] Please see Figure 1-10 The present invention provides the following technical solution:

[0032] Embodiment 1 includes a housing 1, a pair of pulley bodies 2 disposed at the bottom of the housing 1, and a standing foot structure further includes a fixed standing foot 3 slidably disposed at the bottom of the housing 1 and located beside the pair of pulley bodies 2, and an adjustment mechanism 4 for adjusting the position of the fixed standing foot 3; the adjustment mechanism 4 is disposed beside the housing 1, and the adjustment mechanism 4 includes a lifting part 41, a first abutting part 42, and a second abutting part 43; the lifting part 41 is slidably disposed beside the housing 1, and the bottom of the lifting part 41 is connected to the top of the fixed standing foot 3 by fasteners; the first abutting part 42 is slidably disposed beside the lifting part 41. On the side of the first abutting part 42, a plurality of abutting grooves are provided for the second abutting part 43 to abut. The second abutting part 43 is horizontally slidably disposed on the side of the housing 1, and the second abutting part 43 is a toothed structure that can abut with the abutting groove. When the lifting part 41 drives the first abutting part 42 to slide downward, the abutting groove on the side of the first abutting part 42 can drive the second abutting part 43 to slide away from the first abutting part 42. When the first abutting part 42 stops sliding, the second abutting part 43 can abut with the abutting groove on the side of the first abutting part 42.

[0033] It should be noted that the box body 1 is divided into two parts. The bottom of one part is equipped with rollers, while the bottom of the other part is equipped with fixed feet 3. When the box body 1 is tilted, i.e., when the user is on a slope, the box body 1 will tilt, requiring the user to hold onto the box body 1 to ensure it does not tip over. To solve this problem, the lifting part 41 and the first abutment part 42 first slide towards the bottom of the box body 1, during which the second abutment part 43 does not contact the first abutment part 42. When the user stops moving the lifting part 41, the second abutment part 43 can abut against the abutment groove opened to the side of the first abutment part 42. In this state, the second abutment part 43 slides towards the first abutment part 42 but does not affect the downward sliding of the first abutment part 42 because the shapes of the first abutment part 42 and the second abutment part 43 are oppositely arranged inverted tooth-shaped structures. This achieves the fixation of the position of the first abutment part 42. In this state, the fixed foot 3 is located below the roller. At this time, the fixed foot 3 can be in contact with the inclined slope. The box body 1 can be stably supported by the fixed foot 3 and the roller, and the box body 1 is driven to be relatively parallel to the slope when the fixed foot 3 is in the descending state.

[0034] See Figure 4 and Figure 5The adjustment mechanism 4 also includes a fixed plate 44 and a flip-up abutment part 45; the fixed plate 44 is disposed on the top of the lifting part 41; the flip-up abutment part 45 is rotatably disposed on the top of the fixed plate 44, and the flip-up abutment part 45 has an L-shaped structure, and the right end face of the flip-up abutment part 45 has a chamfered structure. When the flip-up abutment part 45 is in a flipped state, it can contact the second abutment part 43 and drive the second abutment part 43 to slide away from the first abutment part 42.

[0035] Specifically, the flip-up abutment part 45 has a circular opening for placing a cup. A hidden slot for storing and concealing the flip-up abutment part 45 is provided on the side of the box body 1. Initially, the flip-up abutment part 45 is located inside the hidden slot on the side of the box body 1. When the box body 1 is tilted, the user first flips the flip-up abutment part 45 away from the box body 1, and then moves it downwards towards the box body 1. It should be noted that when the flip-up abutment part 45 is flipped away from the box body 1, the chamfered structure on the right side of the flip-up abutment part 45 loses its contact with the second abutment part 43. At this point, the second abutment part 43 can slide towards the position of the first abutment part 42 and abut against the abutment slot on the side of the first abutment part 42. Then, the flip-up abutment part 45, the fixing plate 44, and the lifting part 41 continue to descend. During this process, the first abutment part 42 descends, and the second abutment part 43 does not restrict the descent of the first abutment part 42. When the lifting part 41 and the first abutting part 42 stop descending, the second abutting part 43, which is always in contact with the first abutting part 42, can prevent the first abutting part 42 from rising. This enables the descent adjustment of the fixed foot 3 and prevents the fixed foot 3 from sliding upward when in contact with the slope.

[0036] See Figures 6-9 The adjustment mechanism 4 also includes a foot pedal 46, a handle 47, and a limiting part 48; the foot pedal 46 is located on the top of the flip-up abutment part 45; the handle 47 is located on the side of the foot pedal 46; the limiting part 48 has a pair and is respectively located on the top of the lifting part 41, and when the flip-up abutment part 45 flips, it can abut against the top of the limiting part 48 and stop flipping.

[0037] Specifically, a concealed groove is provided on the side of the housing 1 for storing and hiding the foot pedal 46 and the handle 47. When stable support is needed for the housing 1, the user first flips the flip-up abutment 45 using the handle 47 until the flip-up abutment 45 contacts the limiting part 48 and stops flipping. In this state, the foot pedal 46 is located above the flipped-up abutment 45. Then, the user uses their foot to step down on the foot pedal 46. At this time, the fixing plate 44 and the lifting part 41 can slide down. The user does not need to press with their hands, saving the user's strength.

[0038] See Figures 8-10The adjustment mechanism 4 also includes a guide part 49 and a first return spring 491. The guide part 49 is disposed between the lifting part 41 and the fixed plate 44, and a circular opening for limiting the sliding of the guide part 49 is provided on the side of the housing 1. The first return spring 491 is disposed on the outside of the guide part 49. One end of the first return spring 491 is fixed to the guide part 49, and the other end of the first return spring 491 is fixed to the housing 1. When the fixed plate 44 and the lifting part 41 slide downwards, the first return spring 491 is in a compressed state.

[0039] Specifically, when the fixed plate 44 and the lifting part 41 slide downwards, the first return spring 491 is in a compressed state during this process. The second return spring 494 is used to drive the lifting part 41 and the fixed plate 44 back to their initial positions.

[0040] See Figures 6-8 The adjustment mechanism 4 also includes a mounting part 492, a circular column 493, and a second return spring 494. The mounting part 492 is disposed inside the housing 1. Multiple circular columns 493 are disposed on the side of the mounting part 492, and the second abutment part 43 is clearance-fitted with the circular column 493. A mounting chamber for mounting the circular column 493 is provided on the side of the mounting part 492. The second return spring 494 is disposed on the side of the mounting part 492. One end of the second return spring 494 is fixed to the mounting part 492, and the other end of the second return spring 494 is fixed to the second abutment part 43. When the second abutment part 43 slides toward the mounting part 492, the second return spring 494 is in a compressed state.

[0041] Specifically, when the flip-up abutment part 45 and the limiting part 48 are in a flipped abutment state, the second abutment part 43 slides towards the first abutment part 42, but this does not affect the downward sliding of the first abutment part 42, because the shapes of the first abutment part 42 and the second abutment part 43 are oppositely arranged inverted tooth-shaped structures. At this time, the first abutment part 42, the lifting part 41, and the fixed foot 3 can descend stably, and the second return spring 494 is in a compressed state. When it is necessary to store the fixed foot 3, the flip-up abutment part 45 is flipped first. At this time, the chamfered structure of the end face of the flip-up abutment part 45 can contact the second abutment part 43 and drive the second abutment part 43 to slide away from the first abutment part 42. This avoids the phenomenon of the fixed foot 3 locking during storage due to the abutment of the second abutment part 43, thus realizing the descent and rapid storage of the fixed foot 3.

[0042] See Figure 8The adjustment mechanism 4 also includes a positioning part 495 and a blocking part 496; the positioning part 495 is located on the side of the housing 1; the blocking part 496 is located on the side of the fixing plate 44, and the positioning part 495 has an opening for receiving the blocking part 496. When the fixing plate 44 and the lifting part 41 slide down, the blocking part 496 can be driven to slide synchronously in the direction of the opening.

[0043] Specifically, when the lifting part 41 and the fixing plate 44 rise, they can drive the blocking part 496 to rise synchronously and cooperate with the positioning part 495 with a gap. At this time, the blocking part 496 can block the guide part 49, the first return spring 491, the first abutment part 42 and the second abutment part 43. This can improve the aesthetics and prevent foreign objects from falling onto the first abutment part 42 and the second abutment part 43 when storing the fixing foot 3.

[0044] See Figure 3 The fixed foot 3 is made of rubber, and both sides of the bottom of the fixed foot 3 have a chamfered structure.

[0045] Specifically, in order to reduce the tilting of the box 1 when the fixed foot 3 is supporting it, the material of the fixed foot 3 is preferably a rubber anti-slip material.

[0046] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
