Description

Technical Field

[0001] This utility model relates to the field of UPS uninterruptible power supply technology, specifically a portable UPS uninterruptible power supply. Background Technology

[0002] UPS, or Uninterruptible Power Supply, is a type of uninterruptible power supply containing energy storage devices. It is mainly used to provide uninterrupted power to equipment with high power stability requirements. When the mains input is normal, the UPS stabilizes the mains voltage and supplies it to the load. At this time, the UPS is an AC voltage regulator, and it also charges the internal battery. When the mains power is interrupted (power outage), the UPS immediately switches the DC power from the battery to the load and continues to supply 220V AC power through the inverter, so that the load can continue to operate normally and protect the load's hardware and software from damage. UPS equipment can usually provide protection against both overvoltage and undervoltage.

[0003] Furthermore, the application document with publication number CN221380615U mentions a portable UPS uninterruptible power supply. This UPS can move the casing and internal power supply by locking casters. The length of the movable rod can be adjusted by using an adjustment knob to adapt to the user's height. When encountering obstacles during movement, the device can be lifted by the handle in the recess, making the movement process easy and convenient. When movement is not required, the connecting plate, movable rod, and hollow cylinder can be placed in hollow frame one, and the positioning bolt can be placed in hollow frame two. However, there are still some defects that need to be optimized. The specific defects are as follows: In this structure, components such as the connecting plate and movable rod need to be disassembled and placed inside the hollow frame when not in use. The hollow frame occupies extra space, and the small positioning bolt can be lost if not careful. If lost, the entire component cannot be reassembled, making it not very practical.

[0004] Therefore, it is particularly important to design a lightweight UPS uninterruptible power supply to overcome the above-mentioned technical defects and improve its overall practicality. Utility Model Content

[0024] For examples, please refer to Figure 1-4 This utility model provides a technical solution:

[0025] A portable UPS (Uninterruptible Power Supply) includes a main body 1. The main body 1 has symmetrically arranged convex grooves 101 on both sides. Symmetrically arranged support tubes 102 are arranged inside the convex grooves 101. Support blocks 103 are arranged inside the support tubes 102. A fixed shaft 104 is arranged between the two support blocks 103. A pull rod cylinder 105 is symmetrically arranged outside the fixed shaft 104. Pull rods 106 are arranged inside the pull rod cylinder 105. A first limiting component 2 is respectively provided at one end of each support block 103 and pull rod 106. The body has a slot 107 inside, and through holes 108 are symmetrically provided on both sides of the inner side of the slot 107. A second limiting component 3 is provided inside the through hole 108. A lifting rod 109 is provided between the two slots 107. The four corners of the bottom of the main body 1 are provided with moving wheels 110. When the lifting rod 109 is removed and placed aside, the limitation on the pull rod 106 is released. Then, by pressing the limiting button in the first limiting component 2, the telescopic sleeve and the first compression spring are retracted, thereby allowing the support block 103 to slide in the support tube 102 until it moves from the bottom of the main body 1 to the top of the support tube 102. Another limiting hole protrudes, at which point the first compression spring returns to its original state, pushing the limiting block and the corresponding limiting hole to lock together, stabilizing the position of the support block 103. Next, rotate the pull rod cylinder 105 to a 180-degree rotation. At this time, similarly, use the limiting button located on the pull rod 106 to adjust the height of the pull rod 106 to accommodate people of different heights. Then, use the second limiting component 3 to push the push plate to retract the second compression spring. At this time, the locking block retracts into the through hole. Then, the two ends of the lifting rod 109 engage with the slot. After that, release the push plate, and the slot... When engaged with the locking block, the second compression spring returns to its original state, maintaining a tight fit between the locking block and the locking slot, thereby fixing the lifting rod 109. When not in use, the lifting rod 109 can be removed and placed into the placement slot in the convex groove 101 on both sides of the main body 1. The placement slot limits the position of the stored rod and also facilitates the storage of the lifting rod 109. Finally, by operating the self-locking structure on the moving wheel 110, after unlocking, the UPS uninterruptible power supply can be easily moved to the required position by utilizing the flexibility of the moving wheel 110.

[0026] The first limiting component 2 includes a telescopic sleeve, a limiting button, a mounting block, and a first compression spring. The telescopic sleeve includes a large sleeve and a small sleeve, with the small sleeve sliding inside the large sleeve. One end of the small sleeve has a limiting block to prevent the large and small sleeves from separating. The mounting block is fixedly connected to the support block 103 and the pull rod 106. The first compression spring is located outside the telescopic sleeve, with both ends fixedly connected to the mounting block and the limiting button. By pressing the limiting button, the telescopic sleeve and the first compression spring retract, and the limiting button returns to the inside of the limiting hole. The position of the support block 103 and the pull rod 106 is adjusted by their displacement. The second limiting component 3 includes a push plate, a connecting block, a locking block, and a second compression spring. The locking block is fixedly connected to the connecting block. The second compression spring is located on the other side of the connecting block. One end of the second compression spring is fixedly connected to the inner side wall of the through hole 108. The two sides of the lifting rod 109 are symmetrically provided with slots, which are adapted to the slots and the slots. Through the setting of the second limiting component 2, the lifting rod and the pull rod 106 are fixed in position by the cooperation between the slots and the slots. The inside of the convex groove 101 is provided with a placement groove, and the lifting rod 109 is adapted to the placement groove. The lifting rod 109 is placed inside the placement groove to limit the position of the pull rod that is stored, and at the same time, it is convenient to store the lifting rod 109. The support tube 102 and the pull rod cylinder 105 are provided with several limiting holes. The support tube 102 and the support block 103 can slide, and the pull rod cylinder 105 and the pull rod 106 can slide, which is convenient to adjust the height of the pull rod to adapt to different people's heights. The moving wheel 110 is a universal wheel, and the moving wheel 110 is provided with a self-locking structure for easy movement.

[0027] The working process of this utility model is as follows: When using this portable UPS uninterruptible power supply, first remove the lifting rod 109 and place it aside. At this time, the restriction on the pull rod 106 is released. Then, by pressing the limit button in the first limit assembly 2, the telescopic sleeve and the first compression spring are retracted, thereby allowing the support block 103 to slide inside the support tube 102 until it passes through the other limit hole. At this time, the first compression spring returns to its original state, pushing the limit block and the corresponding limit hole to lock together, stabilizing the position of the support block 103. Next, rotate the pull rod cylinder 105 to 180 degrees. At this time, the height of the pull rod 106 is adjusted by using the limit button located on the pull rod 106 to accommodate people of different heights. Then, the second limit is used... Component 3 pushes the push plate to retract the second compression spring. At this time, the locking block retracts into the through hole. Then, the two ends of the lifting rod 109 engage with the slot. After that, the push plate is released, and the slot and the locking block engage. The second compression spring returns to its original state, maintaining a tight fit between the locking block and the slot, thereby fixing the lifting rod 109. When not in use, the lifting rod 109 can be removed and placed in the placement slot in the convex groove 101 on both sides of the main body 1. The placement slot limits the position of the stored rod and also facilitates the storage of the lifting rod 109. Finally, by operating the self-locking structure on the moving wheel 110, after unlocking, the UPS uninterruptible power supply can be easily moved to the required position by utilizing the flexibility of the moving wheel 110.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
