[0024] To fully understand the purpose, features, and effects of the present invention, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings: Please refer to Figures 1 to 4 As shown in the figure, the present invention provides an anti-tipping mobile storage cabinet, which includes: two fixed storage rack modules 1, two track modules 2 and multiple movable storage rack modules 3.

[0025] Each fixed placement rack module 1 has multiple fixing parts 11 at its bottom.

[0026] Each track module 2 includes two fixed seats 21 and a shaft 22. Each fixed seat 21 is arranged adjacently on the top of each fixed placement frame module 1, and both ends of each shaft 22 are located on each fixed seat 21.

[0027] Each movable placement rack module 3 is located between each fixed placement rack module 1. Each movable placement rack module 3 is provided with two movable limiting units 31 and multiple casters 32. Each movable limiting unit 31 is located adjacent to each other on the top of each movable placement rack module 3, and each movable limiting unit 31 is movably mounted on each shaft 22. Each caster 32 is located at the bottom of each movable placement rack module 3.

[0028] Based on the above embodiments, during installation, each fixed placement frame module 1 can be set at an appropriate distance, and each fixed placement frame module 1 can be fixedly set on the ground by the fixed connection part 11. The fixed seats 21 of each track module 2 are arranged adjacent to each fixed placement frame module 1 on the top, and the two ends of each shaft 22 are set on each fixed seat 21. Then, each movable placement frame module 3 is set between each fixed placement frame module 1, and each movable limiting unit 31 is movably set on each shaft 22 at the top of each movable placement frame module 3, thereby completing the installation of each fixed placement frame module 1, each track module 2 and each movable placement frame module 3. In this way, by utilizing the cooperation of each fixed placement frame module 1, each track module 2 and each movable limiting unit 31, each movable placement frame module 3 does not need to be leveled during installation, thus achieving the effect of easy installation.

[0029] When in use, force can be directly applied to each movable rack module 3, causing the top of each movable rack module 3 to move on each shaft 22 via each movable limiting unit 31, while the bottom of each movable rack module 3 moves on the ground via each caster 32. In this way, in addition to moving on the ground via each caster 32 at the bottom of each movable rack module 3, the movement of each movable rack module 3 can also be guided and corrected by the cooperation of each movable limiting unit 31 and each shaft 22 during movement, thereby achieving stable movement and preventing tipping. This allows appropriate space to be moved between each movable rack module 3 (or between each fixed rack module 1 and each movable rack module 3) for personnel to enter and exit to place or retrieve relevant items.

[0030] In addition to the above embodiments, in one embodiment of the present invention, the difference from the above embodiments is that each movable limiting unit 31 is provided with a seat 311, a pulley 312 and a guide wheel 313. Each seat 311 is adjacent to the top of each movable placement frame module 3, each pulley 312 is movably disposed on the top of the inner side of each seat 311, each guide wheel 313 is movably disposed on the bottom of the inner side of each seat 311, each pulley 312 abuts against the top of each shaft 22, and each guide wheel 313 abuts against the bottom of each shaft 22, so that each pulley 312 and each guide wheel 313 correspond to and clamp each shaft 22.

[0031] Based on the above embodiments, when each movable rack module 3 moves, in addition to using the casters 32 at the bottom of each movable rack module 3 to move on the ground, each pulley 312 and each guide wheel 313 can also clamp each shaft 22 at the top and bottom positions to move, so that the guide wheel 313 of each movable limiting unit 31 forms a limiting guide at the bottom of each shaft 22, and the pulley 312 of each movable limiting unit 31 slides with the top of each shaft 22 during movement. Thus, when each movable rack module 3 moves, the movement stroke of each movable rack module 3 is guided and corrected by the cooperation of each movable limiting unit 31 and each shaft 22, thereby achieving stable movement and avoiding tipping, so that appropriate space is moved between each movable rack module 3 (or appropriate space is moved between each fixed rack module 1 and each movable rack module 3) for personnel to enter and exit to place or retrieve related items.

[0032] In addition to the above embodiments, in one embodiment of the present invention, the difference from the above embodiments is that each seat 311 is provided with an elongated hole 3111 and a fixing hole 3112 on both sides. Each elongated hole 3111 is correspondingly provided near the top of each seat 311, and each fixing hole 3112 is correspondingly provided near the bottom of each seat 311. The two ends of each pulley 312 are respectively movably provided in each elongated hole 3111, and the two ends of each guide wheel 313 are respectively provided in each fixing hole. 3112, wherein each pulley 312 is provided with a rolling element 3121, two shafts 3122 and an elastic element 3123. Each shaft 3122 is respectively provided at both ends of each rolling element 3121, and each elastic element 3123 is provided inside each rolling element 3121. The two ends of each elastic element 3123 abut against each shaft 3122. Each pulley 312 is movably provided in each elongated hole 3111 via each shaft 3122, so that each rolling element 3121 abuts against the top of each shaft 22.

[0033] Based on the above embodiments, when each pulley 312 is installed, the shaft 3122 on one side first enters the elongated hole 3111 on one side of each seat 311, and then the shaft 3122 on the other side is compressed in conjunction with each elastic member 3123 and enters the elongated hole 3111 on the other side of each seat 311, thereby achieving the effect of easy assembly.

[0034] When each movable placement rack module 3 moves, in addition to moving on the ground using the casters 32 at the bottom of each movable placement rack module 3, each pulley 312 and each guide wheel 313 can clamp each shaft 22 at the top and bottom positions to move it. This allows the guide wheels 313 of each movable limiting unit 31 to form limiting guides at the bottom of each shaft 22, and allows the rolling elements 3121 of each pulley 312 to slide against the top of each shaft 22 during movement. Since each pulley 312 is movably mounted on each elongated hole 3111 through each shaft 3122, even if each movable placement rack module 3 is not in a horizontal state during movement, it can still be moved by the guide wheels 3121 and the guide wheels 3122. The guide of 13 and the cooperation between the shafts 3122 and the elongated holes 3111 of each pulley 312 correct the stroke during movement, so as to provide smooth rotation during movement. When each movable rack module 3 moves with each caster 32, the movement stroke of each movable rack module 3 is guided and corrected by the cooperation between each movable limit unit 31 and each shaft 22, so as to achieve stable movement and avoid tipping. This allows appropriate space to be moved between each movable rack module 3 (or appropriate space to be moved between each fixed rack module 1 and each movable rack module 3) for personnel to enter and exit to place or retrieve related items.

[0035] In addition to the above embodiments, in one embodiment of the present invention, the difference from the above embodiments is that each guide wheel 313 is provided with a limiting wheel body 3131, two bearings 3132 and a pivot 3133. Each bearing 3132 is respectively provided at both ends of each limiting wheel body 3131. Each pivot 3133 passes through each limiting wheel body 3131 and each bearing 3132, so that each limiting wheel body 3131 is movably provided on each pivot 3133. Both ends of each pivot 3133 are respectively fixed in each fixing hole 3112, and each limiting wheel body 3131 abuts against the bottom of each shaft 22. Each limiting wheel body 3131 has a concave arc portion 3134 and two abutment portions 3135. Each abutment portion 3135 is respectively provided on both sides of each concave arc portion 3134. Each shaft 22 spans across each concave arc portion 3134, and each abutment portion 3135 abuts against both sides of each shaft 22.

[0036] Based on the above embodiments, when setting each guide wheel 313, each limiting wheel body 3131 can be connected to each shaft 22 first, each shaft 22 can be straddled on each concave arc portion 3134, and each stop portion 3135 can be abutted against both sides of each shaft 22. Then, each pivot 3133 can be passed through each limiting wheel body 3131 and each bearing 3132 through each fixing hole 3112, and the two ends of each pivot 3133 can be fixed in each fixing hole 3112 respectively, thereby completing the setting of each guide wheel 313 and achieving the effect of easy assembly.

[0037] When each movable placement rack module 3 moves, in addition to moving on the ground using the casters 32 at the bottom of each movable placement rack module 3, each pulley 312 and each guide wheel 313 can clamp each shaft 22 at the top and bottom positions to move it. This allows the concave arc portion 3134 and the stop portion 3135 of each guide wheel 313 to form a movable limiting guide at the bottom of each shaft 22, and allows the rolling element 3121 of each pulley 312 to slide against the top of each shaft 22 during movement. Since each pulley 312 is movably mounted on each elongated hole portion 3111 through each shaft 3122, and each guide wheel 313 forms a movable limiting with each shaft 22 using its concave arc portion 3134 and stop portion 3135, even if each movable placement rack... Even when module 3 is not in a horizontal position during movement, the travel of movement can still be corrected by the guidance of each guide wheel 313 and the cooperation of each shaft 3122 of each pulley 312 with each elongated hole 3111, so as to provide smooth rotation during movement. When each movable rack module 3 moves with each caster 32, the travel of each movable rack module 3 is guided and corrected by the cooperation of each movable limit unit 31 with each shaft 22, so as to achieve stable movement and avoid tipping. This allows appropriate space to be moved between each movable rack module 3 (or appropriate space to be moved between each fixed rack module 1 and each movable rack module 3) for personnel to enter and exit to place or retrieve related items.

[0038] In addition to the above embodiments, in one embodiment of the present invention, the difference from the above embodiments is that each pivot 3133 has a bushing 3136 at both ends, and each bushing 3136 abuts against the interior of both sides of each seat 311. In this way, by setting each bushing 3136, the limiting wheel body 3131 of each guide wheel 313 is located at the center of the inner side of each seat 311, so as to prevent the guide wheel 313 from shifting during rotation, and to allow each guide wheel 313 to form a movable limit with each shaft 22 by each concave arc portion 3134 and each stop portion 3135, so as to make the concave arc portion 3134 and the stop portion 3135 of each guide wheel 313 stably form a movable limiting guide at the bottom of each shaft 22.

[0039] In summary, the present invention utilizes the cooperation of a fixed placement frame module, a track module, and a movable limiting unit to eliminate the need for horizontal correction during the installation of the movable placement frame module. Furthermore, the movable limiting unit, in conjunction with the shaft, guides and corrects the movement of the movable placement frame module during its movement, thereby achieving the effects of easy installation, stable movement, and prevention of tipping over.

[0040] The present invention has been described in detail above. However, the above description is only one preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent application of the present invention should still fall within the patent coverage of the present invention.
