[0028] like Figures 1 to 5 As shown, a fastening structure for a connector box that is easy to assemble and disassemble includes a box body 1;

[0029] The cover 2 is positioned above the box 1, and its rear side is hinged to the rear side of the box 1. The box 1 has a locking part 11 on its front side, and the cover 2 has a fastening part 21 on its front side. When the cover 2 is closed on the box 1, the fastening part 21 is locked to the locking part 11. When an external force presses on the fastening part 21, the fastening part 21 undergoes elastic deformation and disengages from the locking part 11.

[0030] The connection box in this solution is typically a cable adapter box, used to install couplers or other electrical components. Of course, this connection box can also be other conventional storage boxes.

[0031] Specifically, the connecting box fastening structure includes a box body 1 and a cover body 2, with the cover body 2 hinged to the box body 1. To maintain a stable fastening relationship, a fastening part 21 is provided on the front side of the cover body 2, and a locking part 11 is provided at the corresponding position on the box body 1. When the cover body 2 and the box body 1 are in the closed state, the fastening part 21 is locked onto the locking part 11. Notably, the fastening part 21 of this design can undergo elastic deformation under external force, and the deformed fastening part 21 can easily disengage from the locking part 11. The overall structure is relatively simple and easy to assemble and disassemble.

[0032] Furthermore, the top end of the locking part 11 protrudes outward to form a locking protrusion 111, and the front side of the cover 2 bends toward the side close to the locking part 11 to form the fastening part 21, and the top end of the fastening part 21 abuts against the lower end of the locking protrusion 111.

[0033] In this embodiment, the top of the locking part 11 is provided with a locking protrusion 111, and the front side of the cover 2 is bent to form a fastening part 21. When the cover 2 is closed on the box 1, the top of the fastening part 21 presses against the lower end of the locking protrusion 111, making the two fastened together and not easy to separate. When it is necessary to open the cover 2, the external force squeezes the bent fastening part 21 to make it elastically deformed, and the fastening part 21 will then separate from the locking protrusion 111. The unfastening process is simple, and the connection between the locking part 11 and the fastening part 21 after fastening is relatively stable.

[0034] Furthermore, such as Figure 3 As shown, the vertical cross-section of the fastening part 21 is U-shaped. In this way, the interior of the fastening part 21 has more elastic deformation space, which makes it easier for the fastening part 21 to undergo elastic deformation when compressed, making it easier for the fastening part 21 to disengage from the locking part 11.

[0035] Of course, in other embodiments, the vertical cross-section of the fastening part 21 may also be in other shapes, such as V-shape, to be adapted to different scenarios.

[0036] Furthermore, a through hole 22 is provided on the cover 2, the top end of the locking part 11 is located at the through hole 22, and the middle part of the locking protrusion 111 is provided with a disassembly groove 112 to divide the locking protrusion 111 into at least two protrusions. The disassembly groove 112 is used for inserting external tools to squeeze the fastening part 21, so that the inner wall of the fastening part 21 moves away from the locking part 11, thereby no longer abutting against the lower end of the locking protrusion 111.

[0037] To facilitate opening the cover 2, this embodiment features a through hole 22 on the cover 2 and a disassembly groove 112 in the middle of the locking protrusion 111. The disassembly groove 112 divides the locking protrusion 111 into two protrusions, and the two sides of the top of the fastening part 21 abut against the two protrusions respectively. When the user needs to open the cover 2, a tool can be inserted directly into the disassembly groove 112 from above. When the tool in the disassembly groove 112 pries towards one side of the fastening part 21, it will squeeze the fastening part 21. After being subjected to force, the fastening part 21 undergoes elastic deformation and no longer abuts against the two protrusions, after which the cover 2 can be opened. The disassembly and assembly method is simple, and the fastening structure is not easily damaged.

[0038] Furthermore, such as Figure 2 As shown, the top of the locking protrusion 111 is provided with a guide slope 113 for guiding. The guide slope 113 slopes downward in a direction from the side near the fastening part 21 to the side away from the fastening part 21. In this embodiment, the top of the locking protrusion 111 is provided with a guide slope 113. Specifically, the wire slope is set downward. During the process of fastening the cover 2 and the box 1, the fastening part 21 slides smoothly downward through the downward-sloping guide slope 113 until it is locked with the locking protrusion 111.

[0039] Furthermore, the U-shaped locking portion 11 includes a first side 211 and a second side 212. The first side 211 is located on the side closer to the locking portion 11, and the second side 212 is located on the side away from the locking portion 11. The width of the second side 212 is less than the width of the first side 211.

[0040] Typically, the middle part of the cover 2 protrudes forward in an approximately Π-shaped structure. The upper and lower ends of the Π-shaped structure are not sealed. The Π-shaped structure includes a first side wall, a second side wall, and a third side wall connected end to end. The second side wall connects the first side wall and the third side wall. The fastening part 21 is connected to the second side wall. The height of the second side wall is less than the height of the first side wall / the third side wall on both sides. The top of the second side 212 is connected to the lower end of the second side wall. The end of the second side 212 is connected to the curved bent edge. The other side of the bent edge is connected to the bottom end of the first side 211. The top of the first side 211 is then pressed against the locking protrusion 111.

[0041] During production, the width of the second side 212 is usually less than the width of the first side 211. This ensures that the first side 211 is wider, resulting in a larger contact area with the locking protrusion 111 and a better locking effect. The second side 212 does not need to play a locking role, so its width is set to be smaller. This also prevents the two sides of the second side 212 from connecting with the first and third side walls, making it easier for the fastening part 21 to undergo elastic deformation under pressure. Additionally, the amount of material used can be reduced, thus lowering the manufacturing cost.

[0042] Furthermore, such as Figure 5 As shown, there is a gap 12 between the left and right ends of the locking part 11 and the box body 1. In this way, the two sides of the locking part 11 are not connected to the box body 1. When the user inserts a tool into the disassembly slot 112, he can not only squeeze the fastening part 21, but also squeeze the locking part 11 to make it tilt slightly away from the fastening part 21, so that the fastening part 21 can be more easily disengaged from the locking part 11.

[0043] Furthermore, such as Figures 1 to 6 As shown, the bottom end of the front side of the box body 1 extends outward horizontally to form a mounting plate 13. At least two positions on the outer edge of the mounting plate 13 extend upward to form guide portions 131. The guide portions 131 and the outer wall of the box body 1 have a locking gap 14 for installing an external fixing structure 3.

[0044] In this embodiment, the connecting box can be fixed by wall mounting. In this case, the external fixing structure 3 is a wall-mounting crossbar. The wall-mounting crossbar is usually installed at the engagement gap 14 on the mounting plate 13. When the wall-mounting crossbar is inserted into the engagement gap 14, the guide part 131 on the outer edge of the mounting plate 13 can guide it. It also has a limiting effect on the wall-mounting crossbar. After installation, the two sides of the wall-mounting crossbar are respectively abutted against the outer wall of the front side of the box body 1 and the guide part 131.

[0045] In actual production, two guide parts 131 are usually provided at intervals on both sides of the mounting plate 13. This can provide good guidance and limit for the wall-mounted crossbar without making the overall connection box too complicated. It also requires less raw materials and has a lower production cost. Of course, in some cases, three or four guide parts 131 can also be provided at intervals along the outer edge of the mounting plate 13.

[0046] Furthermore, the outer wall of the front side of the box body 1 is also provided with at least one limiting part 15, which is used to clamp the external fixing structure 3. In order to make the connection between the wall-mounted crossbar and the box body 1 more stable, this embodiment also provides a limiting part 15 on the front side of the box body 1. The limiting part 15 is arranged laterally on the outer wall of the box body 1, and there are usually two of them. The limiting part 15 can clamp the upper surface of one side of the wall-mounted crossbar. At this time, both sides and the upper surface of the wall-mounted crossbar are clamped. Even without using bolts to fix it to the box body 1, the wall-mounted crossbar can be basically prevented from detaching from the box body 1.

[0047] Similarly, in other embodiments, one or three limiting parts 15 may be provided on the box body 1 for fixing the wall-mounting crossbar. In addition, in other embodiments, the wall-mounting crossbar may not be fixed with limiting parts 15, and bolts may be used to fix the wall-mounting crossbar and the mounting plate 13.

[0048] Furthermore, the corners of the box body 1, the cover body 2, and the mounting plate 13 are all rounded. Each corner of the box body 1, the cover body 2, and the mounting plate 13 is designed with rounded corners, and the corners are all arc-shaped, which can ensure the safety of users during the process of picking up, installing, and using them.

[0049] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
