[0020] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] Figures 1-4 As an embodiment of the present invention, a UPS power supply with a protective device includes a protective box 1 and a UPS power supply body 2. The protective box 1 is characterized by having a sliding strip 3 on its inner side wall, and the UPS power supply body 2 has sliding grooves 4 on both sides that are slidably connected to the sliding strip 3. A rectangular groove 5 is provided on one side of the top of the UPS power supply body 2 and a buckle assembly 6 is installed inside it.

[0022] The specific problem addressed in this embodiment is the inability to quickly detach the UPS power supply from the protective device during regular maintenance, which affects the convenience and efficiency of replacement and maintenance. This invention achieves rapid disassembly and assembly of the UPS power supply body 2 within the protective box by using a sliding connection design between the inner sliding strip 3 of the protective box 1 and the sliding grooves 4 on both sides of the UPS power supply body 2. Combined with the wedge-shaped interlocking structure of the trapezoidal block 65 and the trapezoidal grooves 8 on both sides of the latching block 7 in the latching assembly 6, this allows for quick disassembly and assembly of the UPS power supply body 2 within the protective box. During operation, simply pushing the push block 67 through the rectangular groove 9 to compress the spring 63 unlocks the device, solving the problem of cumbersome disassembly of traditional protective devices and improving maintenance efficiency.

[0023] The snap-fit ​​assembly 6 includes a rectangular block 61 and a slot 62 on its surface. Springs 63 are provided on both sides of the rectangular block 61 to connect to a fixing rod 64. A trapezoidal block 65 is provided at one end of the fixing rod 64, and a connecting rod 66 with a push block 67 is connected to its surface. A snap-fit ​​block 7 is provided on the edge of the bottom plate of the protective box 1, and trapezoidal slots 8 are opened on both sides. The trapezoidal block 65 snaps into the trapezoidal slot 8. A rectangular slot 9 is opened on one side of the top surface of the protective box 1, and a cooling fan 10 is installed on the side. In this specific embodiment, the sliding strip 3 on the inner sidewall of the protective box 1 and the UPS power supply body 2... The sliding groove 4 on the side allows for directional pulling. The latch assembly 6 in the rectangular groove 5 at the top of the UPS power supply body 2 pushes the push block 67 to drive the connecting rod 66 and the fixing rod 64 to compress the spring 63, causing the trapezoidal block 65 to disengage from the trapezoidal grooves 8 on both sides of the latch block 7 at the bottom of the protective box 1, thus unlocking it. When pushed in the reverse direction, the latch 62 automatically aligns with the latch block 7 and is reset by the spring 63 to achieve locking. The cooling fan 10 on the side of the protective box 1 delivers airflow to the internal central area, and the waterproof rubber strip on the edge of the rectangular groove 9 prevents external liquid from seeping in. Through the linkage design of the sliding bar and groove guide and the self-locking latch, the UPS power supply body 2 can be quickly disassembled and assembled, improving maintenance efficiency.

[0024] In this specific embodiment, the push block 67 is slidably connected to the limiting groove opened on the surface of the rectangular block 61. The inner wall of the limiting groove is provided with a self-lubricating coating and the groove depth is adapted to the displacement stroke of the push block 67.

[0025] When the push block 67 slides along the limiting groove on the surface of the rectangular block 61, the self-lubricating coating on the inner wall of the limiting groove reduces frictional resistance. The groove depth limits the horizontal displacement range of the push block 67, ensuring that the trapezoidal block 65 is accurately disengaged or reset. The limiting groove structure optimizes the operating feel, prevents the push block 67 from coming off or getting stuck, and improves the reliability of disassembly.

[0026] In this specific embodiment, the two ends of the spring 63 are respectively fixed to the inner wall of the rectangular block 61 and the fixing rod 64. The fixing rod 64 is welded and fixed to the connecting rod 66 and is vertically distributed.

[0027] The preload of spring 63 supports the fixing rod 64 on the inner wall of rectangular block 61. The vertically welded fixing rod 64 and connecting rod 66 form a rigid transmission assembly, ensuring that the pushing force of push block 67 is evenly transmitted to trapezoidal block 65. The linkage design between spring 63 and welding point enhances the stability of the mechanism and extends the service life of buckle assembly 6.

[0028] In this specific embodiment, the air inlet of the cooling fan 10 is provided with a removable dust filter, and its air outlet faces the central area inside the protective box 1. Waterproof adhesive strips are provided on the edge of the rectangular groove 9.

[0029] The dust filter of the cooling fan 10 prevents dust from entering the protective box 1, and the airflow direction of the exhaust port covers the high-temperature area of ​​the UPS power supply body 2; the waterproof strip of the rectangular groove 9 seals the slit through elastic deformation.

[0030] In this specific embodiment, the inclined angle of the trapezoidal groove 8 matches the wedge-shaped surface of the trapezoidal block 65, and a buffer rubber pad is provided at the bottom of the groove.

[0031] The inclined angle of the trapezoidal groove 8 is consistent with the wedge-shaped surface of the trapezoidal block 65. When locked, they form a surface contact. The buffer rubber pad absorbs the impact vibration, reduces the wear of metal parts, the wedge-shaped surface contact enhances the locking force, the buffer pad reduces mechanical wear, and improves the shock resistance of the protective box 1.

[0032] In this specific embodiment, the surface of the slide bar 3 is provided with a wear-resistant nylon layer and the cross-section is a rectangular structure, and the inner wall of the slide groove 4 is provided with a guide groove that matches the slide bar 3;

[0033] The wear-resistant nylon layer on the surface of the slide bar 3 reduces the friction coefficient of the inner wall of the slide groove 4. The rectangular cross section of the slide bar 3 and the guide groove in the slide groove 4 form a tight sliding pair, which restricts lateral displacement. The wear-resistant guide structure maintains the long-term smooth sliding of the slide bar 3 and the slide groove 4 and avoids jamming.

[0034] Working principle: Pushing the push block 67 in the rectangular groove 9 on the top surface of the protective box 1 drives the fixing rod 64 through the connecting rod 66 to compress the spring 63, causing the trapezoidal block 65 to disengage from the trapezoidal grooves 8 on both sides of the locking block 7. After unlocking, the UPS power supply body 2 is slid out along the slide bar 3 and the slide groove 4. During installation, after the locking groove 62 is aligned with the locking block 7, the spring 63 resets and drives the trapezoidal block 65 to wedge into the trapezoidal groove 8 and lock. At the same time, the cooling fan 10 circulates cooling air into the protective box 1. The waterproof rubber strip on the edge of the rectangular groove 9 prevents external liquid from seeping in, realizing quick disassembly and maintenance and efficient protection.

[0035] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0036] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
