Description

Technical Field

[0001] This utility model relates to the field of DC power supply technology, and in particular to a DC power supply limiting device. Background Technology

[0002] In DC power supply applications, precise positioning and stable support are crucial. Currently, existing DC power supply limiting devices on the market have many shortcomings.

[0003] Some limiting devices have poor guiding performance and simple guiding structure. During the installation or relocation of DC power supplies, they cannot provide stable and accurate guidance, which leads to the displacement of the power supply position and affects the normal operation and use of the equipment.

[0004] Some limit devices are not reliable enough, often using simple mechanical blocking and lacking effective elastic buffering and precise positioning mechanisms. When subjected to external impact or vibration, the limit is prone to failure, causing the DC power supply to shift or even be damaged.

[0005] Furthermore, the existing device has an unreasonable support structure with insufficient strength, making it difficult to withstand the weight of the DC power supply, especially after long-term use, which can easily lead to support deformation. Moreover, the design of the fixing components is inadequate, the fixing method is cumbersome, and it is difficult to flexibly adjust to different DC power supply specifications, resulting in low installation efficiency and failing to meet diverse usage needs.
