However, it will be apparent to those skilled in the art that the subject technology can be practiced without

[0039] It is to be understood that the terminology used herein such as "first" and "second", etc. is intended to distinguish one entity or operation from another entity or operation, and is not intended to denote or imply any actual relationship or sequence between the entities or operations.

[0040] The terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0041] Referring to Figs. 1 to 6 As shown in the figure, a folding wheel for an outdoor box comprises a mounting frame 1;

[0042] A shaft 2 is rotatably connected to the mounting frame 1;

[0043] A wheel 3 is mounted on the shaft 2;

[0044] An angle adjuster is arranged between the shaft 2 and the mounting frame 1, and adjusts the included angle between the wheel 3 and the mounting frame 1;

[0045] The angle adjuster comprises an operation shaft 11 rotatably connected to the mounting frame 1, and an angle adjusting mechanism is arranged between the operation shaft 11 and the shaft 2, which adjusts the included angle between the wheel 3 and the mounting frame 1 and positions the wheel 3 at the adjusted position.

[0046] It can be understood that a recess can be arranged on the box 100 for accommodating the folding wheel 3. The wheel 3 is in the storage state, i.e. the wheel 3 is at an angle of 0 or 180 degrees with the mounting frame 1, and the wheel 3 is completely located in the recess.

[0047] The wheel 3 includes two states, i.e. the storage state and the unfolded state. The storage state refers to the angle between the wheel 3 and the mounting frame 1 being 0 or 180 degrees. The unfolded state refers to the angle between the wheel 3 and the mounting frame 1 being between 0 and 180 degrees. Generally, the angle between the wheel 3 and the mounting frame 1 in the unfolded state is 90 degrees.

[0048] It can be understood that when the box is not suitable for arranging the recess, the folding wheel 3 can also be arranged on the bottom wall of the box and protrude from the bottom wall of the box. Since the folding wheel 3 can be folded, the space occupied by the box can be reduced even if the folding wheel 3 is arranged on the bottom wall of the box.

[0049] In some embodiments, the wheel 3 can be a universal wheel. The wheel 3 can also be a common wheel 3.

[0050] In some embodiments, the mounting frame 1 is mounted on the box. For example, the mounting frame 1 can be mounted on the box by screws.

[0052] It can be understood that the worm wheel 21 and the worm 111 have self-locking characteristics. The worm 111 can drive the worm wheel 21 to rotate, but the worm wheel 21 cannot drive the worm 111 to rotate, thereby realizing the function of locking the position of the wheel 3 by the angle adjusting mechanism.

[0053] In some embodiments, the rotating shaft 2 has two roots, and the two rotating shafts 2 are arranged on the two sides of the mounting frame 1 respectively. The operation shaft 11 drives the two rotating shafts 2 to move in opposite directions through the angle adjusting mechanism.

[0054] It can be understood that the two rotating shafts 2 move in opposite directions, so that the wheels 3 on the two rotating shafts 2 are located between the two rotating shafts 2 in the folded state, thereby further reducing the space occupied by the folded folding wheel 3.

[0055] It can be understood that the two rotating shafts 2 move synchronously, which means that the two rotating shafts 2 move in opposite directions at the same time and at the same speed.

[0056] Referring to Figs. 1 to 6As shown in the drawings, in some embodiments, each of the rotating shafts 2 is provided with a worm wheel 21, and each end of the operating shaft 11 is provided with a worm 111, each of which cooperates with an independent worm wheel 21.

[0057] In some embodiments, the worms 111 at both ends of the operating shaft 11 are oppositely oriented.

[0058] It can be understood that when the worms 111 at both ends of the operating shaft 11 are oppositely oriented, a reversing assembly can also be used to make the two rotating shafts 2 oppositely oriented, such as a gear reversing assembly.

[0059] In some embodiments, the wheel 3 comprises a wheel frame and a wheel body 31 rotatably connected to the wheel frame, and the wheel frame is installed on the rotating shaft 2 by key connection.

[0060] Referring to Figs. 1 to 6 As shown in the drawings, in some embodiments, the wheel frame comprises a mounting portion 32 mounted on the rotating shaft 2 and a connecting portion 33 provided on the mounting portion 32, and the mounting portion 32 and the connecting portion 33 are of an integral structure, and the connecting portion 33 is provided with a shaft body 331, and the wheel body 31 is rotatably connected to the shaft body 331.

[0061] In some embodiments, the shaft body 331 can be of an integral structure with the connecting portion 33, and a rolling bearing can be provided between the shaft body 331 and the wheel body 31.

[0062] In some embodiments, the mounting portion 32 is provided with a hole body, and the inner wall of the hole body is provided with a key body, and the rotating shaft 2 is provided with a key groove cooperating with the key body.

[0063] In some embodiments, the key body can be of an integral structure with the mounting portion 32.

[0064] Referring to Figs. 1 to 6 As shown in the drawings, in some embodiments, the mounting frame 1 is provided with lugs 12, and the rotating shafts 2 and the operating shaft 11 are respectively mounted on different lugs 12, and the lugs 12 and the mounting frame 1 are of an integral structure, and a rib plate is provided between the lugs 12 and the mounting frame 1.

[0065] It can be understood that each rotating shaft 2 is fixed by at least two lugs 12, and the operating shaft 11 is fixed by at least two lugs 12.

[0066] The lugs 12 are respectively provided with assembly holes.

[0067] Referring to Figs. 1 to 6As shown, in some embodiments, the operation shaft 11 is a hollow structure, and the operation shaft 11 is provided with an operation part 112 in the middle of the length direction, the operation part 112 is an integral structure with the operation shaft 11, the cross-sectional shape of the operation part 112 is a polygon, and the rotating shaft 2 is a hollow structure.

[0068] Understandably, the operation shaft 11 and the rotating shaft 2 are both hollow structures, which reduces the weight of the folding wheel 3 and makes the box easy to carry.

[0069] Understandably, the circumscribed circle diameter of the operation part 112 is greater than the diameter of the operation shaft 11. The lugs 12 for fixing the operation shaft 11 are respectively located at both ends of the operation part 112. In this scheme, in order to facilitate assembly, the lugs 12 for fixing the operation shaft 11 can be fixed to the mounting frame 1 by screws, or welded to the mounting frame 1.

[0070] The above introduces the subject technical scheme of the utility model and the corresponding details, and it can be understood that the above introduction is only some implementation of the subject technical scheme of the utility model, and some details can be omitted during specific implementation.

[0071] In addition, in some embodiments of the above utility model, a plurality of embodiments can be combined for implementation, and various combination schemes are not listed one by one due to the length. Those skilled in the art can freely combine the above embodiments according to the needs during specific implementation to obtain better application experience.

[0072] Those skilled in the art can obtain other detailed configurations or drawings during implementation of the subject technical scheme of the utility model according to the subject technical scheme of the utility model and the drawings, and it is obvious that these details still belong to the range covered by the subject technical scheme of the utility model without departing from the subject technical scheme of the utility model.
