Description

Technical Field

[0001] This utility model relates to the field of outdoor products technology, specifically to a detachable tow wheel bag. Background Technology

[0002] Folding tents are very common in daily life. They can be opened and folded, making them convenient to use, store, and move. After folding, users usually put the folded tent into a trolley bag for easy movement and transport.

[0003] Most existing wheeled tow bags use a structure where the wheels are permanently fixed to the bottom of the bag. While this fixed design ensures the reliability of the towing function, it also brings a series of problems. First, when not towing, such as when placed in a small space like a car trunk, the protruding wheels not only take up extra space but may also scratch other items or the user. Second, when the wheeled tow bag is placed statically, the wheels at the bottom may cause the bag to slide and become unstable, making it prone to tipping over. Furthermore, when towing wheeled tow bags outdoors, the uneven terrain makes the wheels, being vulnerable parts, extremely difficult to replace and repair once damaged, often requiring specialized tools and skills, and may even render the entire bag unusable. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] It should be noted that in this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element of this utility model must have a specific orientation, and therefore should not be construed as a limitation of this utility model. Example

[0019] Please refer to Figures 1 to 5 As shown, this utility model discloses a detachable tow wheel bag, including a wheel body 1, a bag body 2, and a detachable structure 3. The wheel body 1 is detachably mounted on the bottom side of the bag body 2 via the detachable structure 3. When the bag body 2 needs to be moved, the user tilts it towards the side where the wheel body 1 is located. At this time, the wheel surface of the wheel body 1 will be in contact with the ground, and the user can drag the bag by rotating it. This greatly saves the user's physical strength. In this embodiment, the wheel body 1 includes two sets of wheels on the left and right sides of the same bottom side to ensure stability during use.

[0020] The bag body 2 can take the form of a backpack, travel bag, or suitcase. Its material and internal structure can be designed according to specific uses. In this embodiment, the bag body 2 is a rectangular bag for storing a folded sunshade. On the bottom side of the bag body 2, usually near the user's back, there is a bottom area for mounting the wheels 1. The bag body 2 is provided with a zipper structure for opening the bag body 2 to place the folded sunshade. The detachable structure 3 includes a first connector 31 fixed to the bag body 2 and a second connector 32 integrated with the wheel body 1. The first connector 31 is formed by a first vertical plate 311 and a first horizontal plate 312 vertically connected at the end and integrally molded to form an L-shape. The first vertical plate 311 is fixed to the side of the bag body 2 by screws or riveting, while the first horizontal plate 312 is fixed to the bottom of the bag body 2. This L-shaped structure provides a stable mounting base.

[0021] Correspondingly, the second connecting member 32 is formed by vertically connecting the second vertical plate 321 and the second horizontal plate 322 at the end, and is integrally formed, also forming an L-shape, and the wheel 1 is rotatably mounted on the second connecting member 32.

[0022] The second connector 32, through its second vertical plate 321, cooperates with the first vertical plate 311 of the first connector 31 to achieve a sliding connection in the vertical direction, thereby enabling the wheel body 1 to be detachably installed on the bag body 2 as an integral module.

[0023] On the left and right sides of the front of the second vertical plate 321, a rotating support plate 33 is fixedly installed. Each rotating support plate 33 has a rotating hole 331. The wheel 1 is disposed between the two sets of rotating support plates 33, and the two ends of the rotating shaft of the wheel 1 are rotatably inserted into the rotating holes 331 on both sides, so that the wheel 1 can rotate freely relative to the first connecting member 31 (i.e., relative to the package 2). It should be noted that the wheel 1 can also be an integral assembly with its own bracket and axle, which can be rotatably installed on the second connecting member 32 by other means (such as snap-fit). However, this embodiment shows a preferred method of integrating the rotation function into the first connecting member 31.

[0024] The second vertical plate 321 is slidably engaged with the first vertical plate 311 via a concave-convex sliding structure, ensuring precise and stable sliding. A first L-shaped plate 313 is provided on each of the left and right sides of the front of the first vertical plate 311, with the L-grooves of the first L-shaped plates 313 facing each other. A second L-shaped plate 323 is provided on each of the left and right sides of the front of the second vertical plate 321, corresponding to the first L-shaped plate 313, with the L-grooves of the second L-shaped plates 323 facing away from each other.

[0025] When the wheel 1 is installed, the protrusion of the second L-shaped plate 323 on the second connector 32 can be precisely engaged into the groove of the first L-shaped plate 313 on the first connector 31, forming an interlocking track. This allows the second vertical plate 321 to slide strictly up and down along the first vertical plate 311, avoiding back-and-forth and left-and-right swaying and ensuring the rigidity of the connection.

[0026] The second vertical plate 321 has a fixing pin 324 on its back side, and a fixing hole 314 for the fixing pin 324 to be inserted into is provided on the first vertical plate 311 accordingly. The first horizontal plate 312 also has a positioning hole 315, and the second horizontal plate 322 is provided with a positioning pin 325 that is inserted into the positioning hole 315.

[0027] The back of the second vertical plate 321 is in sliding contact with the front of the first vertical plate 311. When the user pushes the second connecting piece 32 (along with the wheel 1) upwards to its highest position, the fixing pin 324 will precisely engage with the fixing hole 314. At this time, the upper surface of the second horizontal plate 322 will be tightly attached to the bottom surface of the first horizontal plate 312, and the positioning pin 325 will be inserted into the positioning hole 315, forming a comprehensive and stable support and lock, preventing the wheel 1 from slipping off due to vibration during dragging.

[0028] The second vertical plate 321 has an elastic connection port 326 that extends through the front and rear surfaces. The fixing post 324 is not directly fixed to the second vertical plate 321, but is instead mounted on an elastic pressure plate 327. The end of the elastic pressure plate 327 away from the fixing post 324 is fixedly connected to the inner wall of the elastic connection port 326. The end of the elastic pressure plate 327 with the fixing post 324 and its sidewalls have a movable gap with the inner wall of the elastic connection port 326, which allows the elastic pressure plate 327 to undergo elastic deformation within a certain range.

[0029] When it is necessary to disassemble wheel 1, the user only needs to press the end of the fixing pin 324 with their finger from the back of the second vertical plate 321. The elastic pressure plate 327 will then bend inward, causing the fixing pin 324 to disengage from the fixing hole 314. Then, the second connecting piece 32 can be pulled down to remove wheel 1 as a whole.

[0030] An L-shaped groove 316 penetrating the lower wall is provided at the lower front end of the first vertical plate 311. The bottom of the L-shaped groove 316 is machined with a first slope surface 317 along the length direction of the first vertical plate 311. The top (highest point) of the slope surface is close to the fixing hole 314 and is flush with the plate surface of the first vertical plate 311.

[0031] Meanwhile, a second slope surface 328 that fits well with the first slope surface 317 is machined on the front half of the bottom end of the fixed pin 324.

[0032] During installation, the user simply aligns the concave and convex tracks on the upper end of the second connector 32 and pushes it upwards. When the second ramp surface 328 of the fixing pin 324 contacts the first ramp surface 317 at the edge of the L-shaped slot 316, under the continued upward pushing force, the first ramp surface 317 generates an inward component force on the second ramp surface 328, automatically compressing the elastic pressure plate 327 to deform, allowing the fixing pin 324 to slide through. When the fixing pin 324 slides to the fixing hole 314, the elastic pressure plate 327 rebounds, and the fixing pin 324 clicks into the hole, completing the automatic locking. The entire process is seamless, requiring no manual operation of the locking mechanism, providing an excellent user experience. During disassembly, the bag body 2 is opened through the zipper structure, and then the fixing pin 324 is pressed forward from the inside of the bag body 2 to disengage the fixing pin 324 from the fixing pin hole 314. Then, the second connector 32 is pulled down to disengage it from the first connector 31, thereby disassembling the wheel body 1.

[0033] Several bottom supports 4 are also provided on the bottom surface of the bag body 2 on the side away from the wheel body 1 (i.e., the front side). When the bag body 2 is placed vertically, the bottom supports 4 and the wheel body 1 together support the bag body 2, ensuring that it is placed stably and is not easy to tip over.

[0034] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
