Description

Technical Field

[0001] This utility model relates to the field of charging box technology, specifically to a snap-fit ​​structure for the lower cover of a charging box. Background Technology

[0002] The bottom cover of the charging case is an important component of the wireless earphone charging case. It is usually connected to the top cover via a hinge or magnetic structure to form a closed storage space. The snap-fit ​​structure of the bottom cover is a mechanical connection design used to secure the top and bottom covers, commonly found in electronic products such as earphone charging cases and power banks. Its core function is to achieve quick assembly and disassembly through physical interlocking, while ensuring structural strength and sealing.

[0003] However, the existing buckle structure of the charging case bottom cover cannot be engaged at multiple positions during use, resulting in an unstable installation and difficulty in easily canceling the engagement, thus reducing portability and engagement efficiency. Furthermore, it cannot be opened from the middle, limiting its opening as needed and further reducing usability and work efficiency. Therefore, we propose a buckle structure for the charging case bottom cover. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application proposes a snap-fit ​​structure for the lower cover of a charging case, which allows for multi-position snap-fitting, thereby ensuring a secure installation and enabling easy unsnap-fitting, thus improving portability and snap-fit ​​efficiency.

[0005] This utility model provides the following technical solution: a buckle structure for the bottom cover of a charging box, including a cover body. An L-shaped locking block is slidably connected to the bottom of the cover body near the right side along the front-back direction. A fixing block is provided on the left side of the L-shaped locking block, and the top of the fixing block is connected to the bottom of the cover body. A docking post is connected to the left side of the L-shaped locking block. A through hole is opened on the right side of the fixing block. A circular plate is connected to the left end of the docking post through the through hole.

[0006] As a preferred embodiment of this utility model, the outer sleeve of the docking post is provided with a buffer spring, and the left and right ends of the buffer spring are respectively connected to the fixing block and the L-shaped locking block.

[0007] As a preferred embodiment of this utility model, a bonding plate is connected between the two L-shaped blocks, and a number of evenly distributed snap-fit ​​posts are connected to the right side of the bonding plate. A through groove is provided on the top of the cover near the right side, and a pull plate is connected to the top of the bonding plate by bolts. A groove is provided on the right side of the pull plate.

[0008] As a preferred embodiment of this utility model, a slot is provided on the top of the cover near the left side, and guide rails are respectively connected to the top of the cover near the front and rear sides. The guide rails are provided with slots, and sealing plates are slidably connected in the two slots. A fastening screw is connected to the top of the sealing plate near the right side through a screw hole. Threaded holes matching the fastening screws are respectively provided on the top of the cover near the left and right sides.

[0009] As a preferred embodiment of this utility model, the top of the L-shaped card block is connected to a slider by bolts, and the bottom of the cover is provided with a groove that matches the slider.

[0010] The beneficial effects of this utility model are: this technical solution enables multi-position snap-fit, thereby enabling it to be firmly installed and conveniently canceled, improving its portability and snap-fit ​​efficiency. It can also be opened and closed from the middle position, thereby enabling it to be opened as needed, improving its usage efficiency and work efficiency. Attached Figure Description

[0013] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0014] like Figures 1 to 4As shown, a buckle structure for the bottom cover of a charging case includes: a cover body 1, an L-shaped latch 8 that is slidably connected to the bottom of the cover body 1 near the right side along the front and back direction, a fixing block 3 that is provided on the left side of the L-shaped latch 8, and the top of the fixing block 3 that is connected to the bottom of the cover body 1, a docking post 4 that is connected to the left side of the L-shaped latch 8, a through hole that is provided on the right side of the fixing block 3, and a circular plate 2 that is connected to the left end of the docking post 4 through the through hole. In this embodiment, the connecting post 4 is fitted with a buffer spring 5. The left and right ends of the buffer spring 5 are respectively connected to the fixing block 3 and the L-shaped locking block 8, which enables it to be locked in multiple positions, thus enabling it to be firmly installed and conveniently canceled, improving its portability and locking efficiency. Example

[0015] like Figures 1 to 4 As shown, a bonding plate 7 is connected between two L-shaped blocks 8. Several evenly distributed snap-fit ​​posts 6 are connected to the right side of the bonding plate 7. A through groove 11 is provided on the top of the cover 1 near the right side. A pull plate 10 is connected to the top of the bonding plate 7 by bolts. A groove 9 is provided on the right side of the pull plate 10. Implementation plan: A slot 18 is provided on the top of the cover 1 near the left side. Guide rails 14 are connected to the top of the cover 1 near the front and rear sides respectively. The guide rails 14 are provided with slots 12. Sealing plates 15 are slidably connected in the two slots 12. A fastening screw 13 is connected to the top of the sealing plate 15 near the right side through a screw hole. Threaded holes 17 matching the fastening screw 13 are provided on the top of the cover 1 near the left and right sides respectively. A slider 16 is connected to the top of the L-shaped block 8 through a bolt. A sliding groove 19 matching the slider 16 is provided at the bottom of the cover 1, so that it can be opened and closed from the middle position, thereby allowing it to be opened as needed, improving its usage efficiency and work efficiency. Working principle: In use, this technical solution first moves the pull plate 10 through the groove 9. The pull plate 10 drives the locking post 6 and the L-shaped locking block 8 to slide to the left through the bonding plate 7 and squeeze the buffer spring 5. Then the cover 1 is closed. Under the elastic force of the buffer spring 5, the locking post 6 and the L-shaped locking block 8 are locked in the box, allowing for multi-position locking, thus ensuring a firm installation and easy removal of the locking mechanism. This improves portability and locking efficiency. Loosening the fastening screw 13 pulls the sealing plate 15, causing it to slide to the left in the slot 12 and open the slot 18, allowing it to open and close from the middle position. This allows it to be opened as needed, improving its usage and work efficiency.
