[0034] Reference Figure 1 , Figure 2 and Figure 3 The inner wall of the luggage box 1 is elastically connected to the limiting block 27 through the limiting spring 26.
[0035] Reference Figure 1 , Figure 2 and Figure 3 The support column 21 is inserted into the lower surface of the suitcase 1, and the slider 23 is slidably connected to the inner wall of the support column 21 and slides up and down along the inner wall of the support column 21. One end of the compression spring 25 is fixedly connected to the lower surface of the slider 23, and the other end of the compression spring 25 is fixedly connected to the inner wall of the bottom end of the support column 21. When the support column 21 moves upward, the compression spring 25 will be stretched to generate a reaction force. The connecting block 24 penetrates and is slidably connected to the right surface of the support column 21. The positioning ring 22 slides on the outer wall of the support column 21, and the inner wall of the positioning ring 22 fits the outer wall of the support column 21.
[0036] Reference Figure 1 , Figure 2 and Figure 3 The lower surface of the limit block 27 is set as an inclined surface, and the upper surface of the limit block 27 is set as an inclined surface. The inclined surface of the upper surface of the limit block 27 is smaller than the inclined surface of the lower surface. By squeezing the inclined surface of the limit block 27, the limit block 27 will move to the right. When the limit block 27 is inserted into the support column 21, the flat part of the upper surface will contact the inner wall of the top of the support column 21. The limit block 27 is inserted into the inner wall of the limit groove 201, and the support column 21 can be limited. The limit block 27 is slidably connected to the inner wall of the suitcase 1, and the limit block 27 slides left and right along the inner wall of the suitcase 1. One end of the limit spring 26 is fixedly connected to the right surface of the limit block 27, and the other end of the limit spring 26 is fixedly connected to the inner wall of the right side of the suitcase 1. When the limit block 27 moves to the right, it will squeeze the limit spring 26 to generate a reaction force.
[0037] Reference Figure 1 , Figure 4 and Figure 5 The connecting component includes a fender 31, a mounting plate 32 is fixedly connected to the inner wall of the top end of the fender 31, a rotating shaft 33 passes through and is rotatably connected to the left surface of the mounting plate 32, and the centers of the rotating shaft 33, the mounting plate 32 and the fender 31 are located on the same longitudinal horizontal line.
[0038] Reference Figure 1 , Figure 4 and Figure 5 The fender 31 is rotatably connected to the lower surface of the support column 21.
[0039] Reference Figure 1 , Figure 5 and Figure 6 The mounting assembly includes a wheel 41, a positioning block 45 is fixedly connected to the right surface of the wheel 41, and the positioning block 45 can limit the position of the wheel 41. A bolt 42 passes through and is threadedly connected to the left surface of the rotating shaft 33. The right surface of the bolt 42 contacts the left surface of the wheel 41. If the bolt 42 is not removed, the wheel 41 will be blocked and cannot be removed. A slot 401 is provided on the left surface of the wheel 41, and a block 44 is inserted into the inner wall of the slot 401. The shapes of the slot 401 and the block 44 match, and the slot 401 is L-shaped. A cover plate 43 is fixedly connected to the left surface of the block 44, and the cover plate 43 can be installed on the wheel 41 by using the block 44. A buckle groove 402 is provided on the upper surface of the cover plate 43, and the cover plate 43 can be removed by buckling the buckle groove 402.
[0040] Reference Figure 1 , Figure 5 and Figure 6 The wheel 41 is sleeved on the outer wall of the rotating shaft 33, and the right surface of the positioning block 45 contacts the left surface of the mounting plate 32, so that the wheel 41 can be installed between the mounting plate 32 and the left surface of the bolt 42. The wheel 41 fits the outer wall of the rotating shaft 33. A protrusion is provided on the upper surface of the clamping block 44. The protrusion is made of rubber material and has strong deformation ability. It can be inserted into the clamping slot 401 when squeezed by external force, and can also be detached from the clamping slot 401 under the influence of external force.
[0041] Working principle: During use, when it is necessary to disassemble the connecting component and the installing component, you can grab the positioning ring 22 and move it upward. When the positioning ring 22 moves, it will drive the slider 23 and the connecting block 24 to move synchronously. The slider 23 moving upward will stretch the compression spring 25 to generate a reaction force. The slider 23 moving upward will also squeeze the inclined surface of the lower surface of the limit block 27, so that the limit block 27 moves to the right, and then move the support column 21 downward. At this time, the support column 21 moving downward will squeeze the inclined surface of the upper surface of the limit block 27, and the limit block 27 will further move to the right to release the obstruction to the support column 21, so that the support column 21 can be disassembled.
[0042] When the connecting component and the mounting component need to be installed on the suitcase 1, the support column 21 can be plugged into the lower surface of the suitcase 1. When the support column 21 and the suitcase 1 are plugged together, the upper surface of the support column 21 will squeeze the lower surface of the limit block 27. After being squeezed, the limit block 27 will move to the right to squeeze the limit spring 26 to generate a reaction force, and the limit block 27 moving to the right will release the obstruction to the support column 21, so that the support column 21 can be fully plugged into the suitcase 1. After the plugging is completed, the support column 21 is rotated to align the limit block 27 with the limit groove 201. After the alignment, the limit block 27 will be pushed by the reaction force of the limit spring 26 to plug into the limit groove 201 to limit the support column 21, which can ensure the stability of the device. Through the above operations, the connecting component and the mounting component can be quickly disassembled and assembled.
[0043] When the wheel 41 is damaged and needs to be replaced separately, first buckle the buckle slot 402 and buckle the cover 43. When the cover 43 is buckled, the block 44 will also be separated from the slot 401 and the bolt 42 will be exposed at this time. Then unscrew the bolt 42 to release the limit on the wheel 41, and then remove the damaged wheel 41, and then put the new wheel 41 on the shaft 33. After the sleeve connection is completed, screw the bolt 42 on the shaft 33 to limit the wheel 41, and then align the block 44 with the slot 401 and plug it in. When plugging in, the protrusion on the block 44 will be squeezed and deformed. When the block 44 and the slot 401 are plugged in, the protrusion on the block 44 will fit with the protrusion inside the slot 401, thereby fixing the cover 43 on the wheel 41 to protect the bolt 42 and the wheel 41.
[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
