Description

Technical Field

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

[0002] An uninterruptible power supply (UPS) is a system device that connects a battery to a main unit and converts DC power to AC power through the main unit's inverter and other module circuits. UPS is mainly used to provide a stable and uninterrupted power supply to single computers, computer network systems, or other power electronic equipment such as solenoid valves and pressure transmitters, ensuring the uninterrupted operation of these devices and instruments, and preventing data loss, telephone communication network interruption, or loss of control of instruments. Existing UPS power supplies are prone to damage from bumps and knocks during transport, lack suitable safety protection mechanisms, and the disassembly and locking of safety protection mechanisms are relatively troublesome, lacking suitable quick-locking mechanisms. In addition, the overall length of the carrying lever mechanism is fixed during use, making it inconvenient to adjust, and its practicality needs to be improved. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a portable UPS power supply with the following advantages:

[0016] 1. The protective shell is designed to be detachable on both sides and has an integrated reinforcing bracket. This design significantly enhances the rigidity and impact resistance of the shell while achieving a lightweight design, effectively protecting the internal components. The positioning rod and the positioning holes of the fixing frame work together to ensure accurate and convenient installation, guarantee carrying safety, and prevent damage to the internal power supply unit caused by accidental bumps during carrying.

[0017] 2. Through the design of the locking seat, the locking seat is raised and lowered by a unique single adjusting rod, which drives the four corner locking rods to simultaneously insert or disengage from the locking holes of the protective shell. This achieves one-click, quick, and stable locking or releasing of the protective shells on both sides. The guide rod ensures precise movement, the retaining ring limits the stroke, and the threaded connection provides self-locking and anti-loosening, which greatly simplifies the disassembly and assembly process and ensures the overall structural stability.

[0018] 3. Through the design of the U-shaped base, the device achieves flexible adjustment of the handle height by sliding the U-shaped plate within the U-shaped base and cooperating with multiple limit holes; the spring-loaded limit rod design allows users to unlock and slide to adjust the height simply by pulling the limit ring, and automatically locks after releasing, making operation extremely simple, safe and secure. Combined with the universal wheels, it greatly improves the effortless and comfortable movement of the device under different road conditions and user postures, while the L-shaped plate provides additional protection and convenient storage.

U-shaped plates 11 are slidably provided inside the U-shaped seats 10, and grooves 12 are symmetrically provided on the U-shaped seats 10 corresponding to the U-shaped plates 11.

[0029] In this embodiment, when the device needs to be carried and transferred, the protective shell 5 is installed in conjunction with the fixing frame 4, the positioning rod 7 and the positioning hole 8 are installed and positioned, and the protective shell 5 with the reinforcing bracket 6 cooperates with the fixing frame 4 to achieve safety protection during the overall carrying process and avoid accidental bumps and damage.

[0030] More specifically, during the carrying process, the U-shaped plate 11 is slidably adjusted relative to the groove 12 of the U-shaped seat 10, making it convenient for users of different heights to hold and pull to adjust. The universal wheels 3 drive the entire device to move and transfer.

[0031] Please see Figure 1 , Figure 2 and Figure 4 As one implementation method for grip adjustment: the left and right sides of the outer end face of the U-shaped seat 10 are provided with a limiting rod 13 through the groove 12. The left and right ends of the U-shaped plate 11 are provided with limiting holes 14 corresponding to the limiting rod 13. Multiple limiting holes 14 are provided at intervals. The outer ends of the two limiting rods 13 are provided with limiting rings 15. Springs 16 are connected between the two limiting rings 15 and the U-shaped seat 10. The springs 16 are fitted on the outer ends of the limiting rods 13. The rear side of the upper end face of the fixed frame 4 is provided with an L-shaped plate 17 corresponding to the U-shaped seat 10. Two L-shaped plates 17 are symmetrically arranged.

[0032] Specifically, by grasping the limiting ring 15, the limiting rod 13 is pulled outward, the spring 16 is stretched, and the U-shaped plate 11 slides relative to the groove 12 of the U-shaped seat 10 for adjustment. After adjusting to the appropriate position, the limiting ring 15 is released, the spring 16 retracts, and the limiting rod 13 is reset and inserted into the corresponding limiting hole 14, which is convenient for users of different heights to hold and adjust. When the whole thing is folded up, the L-shaped plate 17 is rotated, and the L-shaped plate 17 and the U-shaped seat 10 cooperate to achieve the folded state and lock.

[0033] Please see Figures 1-3 and Figure 5 As one method of installation and locking: the fixed frame 4 is provided with a locking seat 18 inside, and locking rods 19 are provided at the four corners of the upper end face of the locking seat 18. Locking holes 20 are symmetrically opened on the two protective shells 5 corresponding to the locking rods 19. An adjusting rod 21 is rotatably provided on the fixed frame 4.

The guide rod 23 and the guide hole 24 cooperate to guide the sliding. The retaining ring 25 limits the sliding to prevent slippage. The locking seat 18 drives the locking rod 19 to slide up and down, and the corresponding locking hole 20 is inserted to lock the protective shell 5.

[0035] In summary, the overall equipment is in use:

[0036] When the protective shell 5 is in the installation state, the protective shell 5 is installed in accordance with the fixed frame 4. The positioning rod 7 and the positioning hole 8 cooperate to install and position. After the initial positioning and installation, the adjusting rod 21 is rotated. The adjusting rod 21 and the adjusting hole 22 are threaded together. The guide rod 23 and the guide hole 24 cooperate to guide, so as to realize the overall lifting and adjustment of the locking seat 18. The locking seat 18 drives the locking rod 19 to be inserted upward into the locking hole 20 of the protective shell 5 to realize the installation and locking, and realize the safety protection when carrying and transferring.

[0037] When in handheld adjustment mode, grasp the limiting ring 15 and pull the limiting rod 13 outward. The U-shaped plate 11 slides relative to the groove 12 of the U-shaped seat 10 for adjustment. After adjusting to a suitable position according to the user's height, release the limiting ring 15, the spring 16 retracts, and the limiting rod 13 resets and inserts into the corresponding limiting hole 14.

[0038] When in the carrying and transfer state, after the overall installation and adjustment are completed, the user holds the outermost end of the U-shaped plate 11, and the universal wheel 3 drives the whole device to move. The protective shell 5 and the fixed frame 4 cooperate to provide safety protection for the power supply body 1 during the carrying and transfer process. The reinforcing bracket 6 provides enhanced protection for the protective shell 5 to avoid accidental bumps and damage during carrying.
