When pulling out a module, operators may use improper operation, such as excessive force, causing the module to exceed its designed travel and accidentally fall. This can not only damage the module itself but also pose a threat to the operator's safety. Although various devices are currently available on the market to prevent modules from falling, they are generally complex and costly. Utility Model Content

[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0038] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.
[0039] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.
[0041] Please refer to Figure 1 and Figure 2 , which is a preferred embodiment of the present utility model, the uninterruptible power supply cabinet includes: a rack 30, including a guide structure 312 and a limiting structure 313 set on the exit path; a power module 20, slidably mounted on the rack 30; an anti-fall mechanism 10, deformably mounted on the power module 20, including a limiting block 100 and a limiting column 200; when the power module 20 exits the rack 30, the limiting column 200 is configured to cooperate with the guide structure 312 to exit the limiting structure 313; the limiting block 100 is configured to press the limiting column 200 when it abuts against the limiting structure 313, so that the limiting block 100 exits the limiting structure 313.
[0042] During the process of pulling out the power module 20, the guide structure 312 on the rack 30 gradually squeezes the limiting post 200 on the limiting block 100, and the limiting block 100 can undergo elastic deformation until the limiting post 200 leaves the rack 30, and the limiting block 100 returns to its original state. After continuing to pull out the power module 20 for a certain distance, the limiting block 100 is set to press against the limiting structure 313, and the power module 20 cannot continue to move forward. At this time, the operator can extend his finger to press the limiting post 200, and the limiting block 100 undergoes elastic deformation again, driving the limiting block 100 to disengage from the limiting structure 313, and then the power module 20 can continue to be pulled out.
[0043] The anti-fall mechanism 10 of the uninterruptible power supply cabinet has the characteristics of simple structure, low cost and reliable structure. The limit column 200 is set within the reach of fingers. When the operator pulls out the power module 20, he can ensure that both hands are always holding the power module 20, preventing the dangerous situation of holding the power module 20 with one hand.
[0044] like Figure 1 As shown, the uninterruptible power supply cabinet includes an anti-fall mechanism 10, a power module 20 and a rack 30. Each of the above components will be described in further detail below.
[0045] like Figure 1 and Figure 2 As shown, the rack 30 is generally rectangular and box-shaped, and can accommodate multiple power modules 20. The rack 30 includes a side panel 31, which is provided with an exit 311 that is generally L-shaped. A guide structure 312 and a limit structure 313 are provided at the end of the exit 311 facing the exit direction. The guide structure 312 and the limit structure 313 are arranged side by side in a perpendicular exit direction. That is, in this embodiment, the guide structure 312 and the limit structure 313 are arranged in a vertical direction. When the power module 20 is installed in the rack 30, the limit block 100 and the limit post 200 are arranged to be located within the exit 311. The limit post 200 is arranged in a straight line with the guide structure 312, and the limit protrusion 111 is arranged in a straight line with the limit structure 313, and both are parallel to the exit direction of the power module 20. Specifically, the guide structure 312 is a flat plate inclined toward the exit direction, and the limiting structure 313 is a frame of the rack 30. Other structures of the rack 30 are prior art and will not be described in detail here.
[0046] like Figure 3 and Figure 4As shown, the power module 20 includes a chassis 21 having a first hole 211 and a second hole 212 defined therein. The anti-drop mechanism 10 is fixedly mounted within the chassis 21, with the limiting protrusion 111 and limiting post 200 respectively positioned within the first hole 211 and the second hole 212. The anti-drop mechanism 10 is concealed within the chassis 21, thereby maintaining the integrity of the power module 20's appearance and reducing the risk of scratches caused by the exposed anti-drop mechanism 10.
[0047] like Figure 5 As shown, the anti-fall mechanism 10 includes a stopper 100 and a stopper post 200. The first end of the stopper 100 is fixedly connected to the power module 20; the second end of the stopper 100 is free, and the stopper post 200 is fixedly mounted on the second end of the stopper 100. The stopper 100 is made of a material with elastic deformation, such as metal. With this arrangement, the stopper 100 can be elastically deformed by operating the stopper post 200, and the stopper 100 can automatically reset.
[0048] Specifically, the limiting baffle 100 also includes a first sub-board 110 and a second sub-board 120 vertically connected together, so that the limiting baffle 100 is in an "L" shape as a whole. The first end of the first sub-board 110 is provided with a first mounting hole 114, which can be fixed to the inner wall of the chassis 21 by fasteners such as rivets, and fixedly connected to the power module 20. The second end of the first sub-board 110 is fixedly connected to the second sub-board 120. Preferably, the first sub-board 110 and the second sub-board 120 are integrally formed. The second sub-board 120 is provided with a second mounting hole 121, and the limiting column 200 is passed through the second mounting hole 121, so that the limiting column 200 is fixedly mounted on the second sub-board 120. Preferably, the limiting column 200 is a pin.
[0049] like Figure 5 As shown, the limiting block piece 100 includes a limiting protrusion 111, which is disposed between the first and second ends of the limiting block piece 100 and is configured to abut against the limiting structure 313. The limiting protrusion 111 includes a limiting surface 112, which is disposed intersectingly with the extension direction of the limiting block piece 100. The limiting surface 112 is preferably disposed perpendicular to the extension direction of the limiting block piece 100, or is inclined toward the limiting post 200.
[0050] like Figure 6 and Figure 7As shown, when the power module 20 is installed on the rack 30, the limiting surface 112 and the limiting post 200 are away from the limiting structure 313 and the guide structure 312. During the process of pulling out the power module 20, the guide structure 312 on the rack 30 gradually squeezes the limiting post 200 on the limiting block 100, and the limiting block 100 can undergo elastic deformation until the limiting post 200 leaves the rack 30 and the limiting block 100 returns to its original state. After the power module 20 is pulled out for a certain distance, as shown in FIG. Figure 8 and Figure 9 As shown, the limiting surface 112 of the limiting block 100 abuts against the limiting structure 313 . Under the limitation of the limiting structure 313 , the power module 20 cannot move forward any further.
[0051] The above content is only a preferred embodiment of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scope based on the concept of the present invention. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of the present invention.
