Description

Technical Field

[0001] This utility model relates to the field of power box cover technology, specifically a power box cover assembly. Background Technology

[0002] As a core component of electronic devices, the safety and reliability of the power supply are of paramount importance. The power supply cover assembly is an important part of the power supply, mainly used to protect the positive and negative terminals and other key components inside the power supply, prevent external contaminants such as dust and moisture from entering, and ensure the stable operation of the power supply.

[0003] Traditional power supply box cover assemblies typically use a simple direct connection between the cover and the power supply body. However, the connection between the cover and the power supply body is too complicated, requiring the removal of multiple parts each time it is disassembled. This not only results in the loss of parts but also makes the operation cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a power supply box cover assembly, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power supply box cover assembly, comprising a power supply body and a cover body, wherein positive and negative terminals are fixed on the power supply body, and a snap ring is fixed on the outer side of the positive and negative terminals at the upper end of the power supply body, and a sleeve is fixed at the lower end of the cover body, the sleeve being matched and snapped with the snap ring, a limiting frame is fixed at the upper end of the power supply body, and the lower edge of the cover body is inserted into the inner side of the limiting frame, and a connecting mechanism is provided between the upper end of the power supply body and the lower edge of the cover body.

[0006] Furthermore: the connecting mechanism includes a fixing clip and a pressure block. The fixing clip is fixed on both sides of the upper end of the power supply body, and the pressure block is fixed on both ends of the outer side of the cover. The contact ends of the pressure block and the fixing clip are inclined and matched. A lever is fixed on the outer end of the fixing clip.

[0007] Furthermore: a U-shaped hanging rod is fixed to the upper end of the power supply body, and a sliding plate is fixed to one end of the cover near the U-shaped hanging rod. The sliding plate is slidably connected to the U-shaped hanging rod. After the cover is disassembled, it moves along the U-shaped hanging rod via the sliding plate, which facilitates the placement and disassembly of the cover.

[0008] Furthermore: The cover is symmetrically fixed with buckle plates at both ends, and the upper end of the buckle plates is coated with the corresponding positive and negative terminal marks. The cover can be pulled out by placing a finger on the lower end of the buckle plate and pulling it upwards, making it easy for the user to remove the cover.

[0009] Furthermore, the buckle ring is elastically designed, and the upper end of the buckle ring is arc-shaped and multi-lobed.

[0010] Furthermore, the U-shaped hanging rod is located at the middle of the edge of the power supply body.

[0011] Furthermore, the hanging rod is designed in an inverted U-shape, and its end is positioned to limit the sliding plate.

[0012] This utility model provides a power supply box cover assembly. Compared with the prior art, it has the following advantages:

[0013] This power supply box cover assembly, through the matching snap-fit ​​structure of the sleeve and the snap-fit ​​ring, and the insertion setting of the lower edge of the cover and the limiting frame, effectively prevents dust and other external contaminants from entering the power supply, ensuring stable operation of the power supply. The snap-fit ​​structure of the sleeve and the snap-fit ​​ring, as well as the insertion design of the limiting frame, significantly improve the connection stability between the cover and the power supply body, avoiding loosening problems caused by vibration or temperature changes. Through the design of the fixing clip, pressure block and toggle plate in the connection mechanism, the installation and removal process of the cover is more convenient. No tools are needed; the operation can be completed simply by pressing or toggling, greatly improving the ease of use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5This utility model provides a technical solution: a power supply box cover assembly, specifically composed of a power supply body 1 and a cover 2. Positive and negative terminals 11 are fixed on the power supply body 1 (this is existing technology and will not be described in detail here). A snap-fit ​​ring 12 is fixed to the outer side of the positive and negative terminals 11. A sleeve 4 is fixed to the lower end of the cover 2, and the sleeve 4 is matched and snapped into place with the snap-fit ​​ring 12. A limiting frame 8 is fixed to the upper end of the power supply body 1, and the lower edge of the cover 2 is inserted into the inner side of the limiting frame 8. The upper end of the power supply body 1 and the lower end of the cover 2 are connected to the side walls of the cover 2. The cover 2 is provided with a connecting mechanism. After the connecting mechanism is opened, the cover 2 can be pulled vertically upward from the limiting frame 8. The limiting frame 8 can provide a seal, and the positive and negative terminals 11 are fitted inside the sleeve 4. The sleeve 4 and the snap ring 12 are matched and snapped together. The sleeve 4 and the snap ring 12 can improve the connection stability of the cover 2. This not only improves the sealing effect of the positive and negative terminals 11 and reduces the entry of external dust, but also improves the connection stability between the cover 2 and the power supply body 1, preventing loosening during use.

[0022] The connecting mechanism includes a fixing clip 6, which is fixed on both sides of the upper end of the power supply body 1. Pressure blocks 5 are fixed on both ends of the outer side of the cover 2. The contact ends of the pressure blocks 5 and the fixing clip 6 are inclined and matched. A lever 7 is fixed on the outer end of the fixing clip 6. When the cover 2 needs to be removed, the lever 7 is moved outward, and the fixing clip 6 is moved outward by the lever 7, so that the fixing clip 6 is separated from the pressure block 5, and the cover 2 can be removed. At the same time, when the cover 2 is installed, the pressure block 5 is aligned with the fixing clip 6, the cover 2 is matched with the limiting frame 8, and the cover 2 is pressed down to fix the cover 2 to the power supply body 1, so that the installation is convenient and the disassembly is easy.

[0023] A hanging rod 9 is fixed at the upper end of the power supply body 1. The hanging rod 9 is U-shaped. A sliding plate 10 is fixed at the end of the cover 2 near the hanging rod 9. The sliding plate 10 is slidably connected to the hanging rod 9. After the cover 2 is removed upwards, it moves along the hanging rod 9 via the sliding plate 10. This makes it convenient to place the cover 2 and also convenient to remove the cover 2.

[0024] The cover 2 is fixed with buckle plates 3 at both ends. The buckle plates 3 are symmetrically arranged. By placing your finger on the lower end of the buckle plate 3, you can pull the cover 2 upwards. The buckle plates 3 make it easy for users to remove the cover 2. The upper end of the buckle plate 3 is painted with the corresponding positive and negative terminals 11.
