[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixed", etc. should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or an integral whole; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
[0025] The distribution box provided in the embodiment of the utility model has a structure in which the cover plates can be interchangeably installed. Figures 1 to 5 As shown, it includes a box body 1 and a box cover 2; at least two installation windows 21 are provided on the box cover 2, and a cover plate 3 is installed at each installation window 21, and the cover plates 3 at at least two installation windows 21 can be installed interchangeably. The interchangeable installation of the cover plates 3 allows different functional modules or actual needs to be flexibly replaced and combined to meet different user needs, increase the customizability and scalability of the equipment, and realize standardized production, which is conducive to reducing manufacturing costs and improving production efficiency, and is also convenient for inventory management.
[0026] like Figure 2As shown, a downwardly recessed groove 22 is formed on the outer surface of the box cover 2 around the installation window 21, and the cover plate 3 is suitable for being embedded in the groove 22 for installation. The outer edge shape of the groove 22 matches the outer edge shape of the cover plate 3, and the interchangeable cover plates 3 all have the same outer edge shape. The design of the groove 22 can effectively combine the cover plate 3 with the box cover 2, reducing the impact of the external environment on the internal components, and the cover plate 3 is fully or partially embedded in the groove 22, which can avoid the cover plate 3 protruding too much from the surface of the box cover 2, reduce conspicuous seams, and make the distribution box beautiful in appearance.
[0027] In order to reliably fix the cover plate 3 and the box cover 2, a plurality of screw through holes 23 are provided on the bottom surface of the sink 22, and screw holes are provided on the inner side surface of the cover plate 3 at positions corresponding to the screw through holes 23. The fastening screws pass through the screw through holes 23 and are screwed into the screw holes, thereby fixing the cover plate 3 and the box cover 2. The screw fastening connection can ensure a good structural connection between the cover plate 3 and the box cover 2, thereby improving the overall stability and seismic resistance, and the screw installation operation is simple.
[0028] In order to further improve flexibility and versatility, all cover plates 3 on the box cover 2 are arranged to be interchangeable; in actual operation, some cover plates 3 can also be arranged to be interchangeable.
[0029] In some embodiments, as Figure 4 and Figure 5 As shown, at least one cover plate 3 is provided with a mounting hole 31, the inner wall of which has two half-turn threads 32. The two half-turn threads 32 have the same rotation direction and are centrally symmetrically arranged. A socket 33 is mounted in the mounting hole 31, and the outer wall of the socket 33 has a double-thread structure 331 that engages with the two half-turn threads 32. When installing the socket 33, the lower end of the socket 33 is inserted into the mounting hole 31 and twisted half a turn so that the double-thread structure 331 engages with the two half-turn threads 32 to secure the socket 33. This greatly improves the convenience of installing the socket 33, facilitates user maintenance or replacement as needed, and enhances the maintainability of the product. The half-turn thread 12 is not a complete turn of thread, and the central angle of the half-turn thread is preferably set to 90 to 180 degrees, such as 90 degrees (i.e., one-quarter of a full turn of thread), 120 degrees (i.e., one-third of a full turn of thread), or 180 degrees (i.e., one-half of a full turn of thread).
[0030] In some embodiments, as Figure 3 and Figure 5As shown, a locking block 34 and a spring are movably provided at the mounting hole 31 on the cover 3. The spring (not shown) provides elastic force for the locking block 34. A locking hole 332 is provided on the socket 33 at a position corresponding to the locking block 34. When the socket 33 is installed in place, the elastic force of the spring causes the locking block 34 to engage with the locking hole 332, thereby locking the socket 33 to prevent it from rotating and loosening, ensuring the reliability of the fixed installation of the socket 33. As a variation, in actual operation, the positions of the mounting hole 31 and the locking block 34 can be interchanged, that is, the mounting hole 31 is set on the cover 3, and the locking block 34 is correspondingly set on the socket 33.
[0031] In some embodiments, a sealing ring is compressed between the socket 33 and the cover plate 3. The sealing ring is disposed around the mounting hole 31, thereby sealing the gap between the socket 33 and the cover plate 3 and preventing dust or water from entering the interior of the housing 1 through the mounting hole 31. To facilitate the positioning and installation of the sealing ring, a sealing groove can be provided on the socket 33 and / or the cover plate 3, and the sealing ring can be embedded in the sealing groove.
[0032] In some embodiments, at least two mounting holes 31 are provided on the cover plate 3, and all mounting holes 31 have the same structure and equal diameter. Since the structure and size of each mounting hole 31 are consistent, the user can freely switch the installation position of the socket 33 between different mounting holes 31 according to actual needs, thereby improving the practicality of the product.
[0033] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
