[0036] The weak current box is a centralized box for weaker voltage lines.

[0037] The door of an existing weak-current box is generally formed by bending through a sheet metal process. During the use of the weak-current box, the sheet metal door is integrally covered on the opening of the box body. Since a large number of electrical components are installed in the weak-current box, the sheet metal door is prone to generate a larger and stronger magnetic field, interfering with signal transmission between electrical components, thereby affecting the normal use and operation of the weak-current box.

[0038] Based on this, see Figure 1 and Figure 2 An embodiment of the present application provides a door panel structure, which includes a main frame 100 and a cover plate assembly 200.

[0039] The main frame 100 encloses a first opening 110. The cover assembly 200 includes a cover frame 210 and a glass panel 220. The cover frame 210 encloses a second opening, and the glass panel 220 fills the second opening. The cover assembly 200 is hinged to the main frame 100 to drive the glass panel 220 to rotate and cover or open the first opening 110.

[0040] It should be noted that the door panel structure of the present application is preferably configured on the weak current box, and is used to cover or open the opening of the weak current box. In the present application, the shape of the main frame 100 can be, but not limited to, a rectangular frame, a trapezoidal frame, a regular polygonal frame, etc., and correspondingly, the first opening 110 can be, but not limited to, a rectangular opening, a trapezoidal opening, a regular polygonal opening. It is not difficult to understand that the first opening 110 formed by the main frame 100 can be adapted to communicate with the opening of the weak current box.

[0041] It should also be noted that in the cover frame 210 of the present application, the second opening formed by the cover frame 210 is preferably a through opening. Of course, the second opening formed by the cover frame 210 can also be a groove structure, which is not specifically limited. The glass panel 220 can be fixed to the cover frame 210 by glass glue to form a filling for the second opening. The glass panel 220 can also be detachably fixed to the cover frame 210 by screws or buckles, etc., so as to facilitate the disassembly and replacement of the glass panel 220.

[0042] It can be understood that when the door panel structure of the present application is configured on the weak-current box, the main frame 100 is installed at the box opening of the weak-current box, and the first opening 110 formed by the main frame 100 is connected to the box opening of the weak-current box. When the user needs to close the box opening of the weak-current box, the cover assembly 200 can be manually pushed to make the cover assembly 200 rotate as a whole relative to the main frame 100 in the direction close to the first opening 110, so that the glass panel 220 on the cover assembly 200 completely covers the first opening 110 to achieve the closure of the box opening of the weak-current box.

[0043] It is not difficult to understand that the present application realizes the closing of the box opening of the weak-current box by covering the first opening 110 with the glass panel 220. During the use and operation of the weak-current box, the glass structure of the glass panel 220 will not generate an interfering magnetic field, that is, the glass panel 220 will not interfere with the signal transmission of the electrical components in the weak-current box. In this way, the interference of the door panel structure on the signal transmission of the electrical components in the weak-current box is greatly reduced, thereby ensuring the normal use and operation of the weak-current box and effectively improving the performance of the weak-current box.

[0044] In some embodiments of the present application, the glass panel 220 is constructed of tempered glass. In this way, the glass panel 220 is ensured not to generate an interfering magnetic field to the electrical components in the weak current box, and the overall structural strength of the glass panel 220 is improved, thereby improving the overall structural strength of the weak current box and enhancing the overall safety protection performance of the weak current box.

[0045] In some embodiments of the present application, see Figure 2 and Figure 3 The door panel structure further includes a rotating shaft 300 , and the cover frame 210 is rotatably mounted on the main frame 100 via the rotating shaft 300 .

[0046] Specifically, there are two rotating shafts 300, which are respectively arranged at opposite ends of a side of the cover frame 210. Correspondingly, two installation positions are provided on the side of the main frame 100 close to the cover frame 210. The two rotating shafts 300 on the cover frame 210 are correspondingly rotatably installed on the two installation positions of the main frame 100 to realize the function of rotating the cover frame 210 and the glass panel 220 on the cover frame 210 relative to the main frame 100, ensuring that the glass panel 220 on the cover assembly 200 normally covers or opens the first opening 110 of the main frame 100, while improving the rotation stability of the cover assembly 200.

[0047] Further, see Figure 3 and Figure 4 The main frame 100 is provided with a first blind hole (not shown in the figure), the cover frame 210 is provided with a second blind hole (not shown in the figure), the rotating shaft 300 includes a first shaft segment 310, a second shaft segment 320 and a third shaft segment 330 along its own axial direction, the outer diameter of the second shaft segment 320 is larger than the outer diameter of the first shaft segment 310 and the outer diameter of the third shaft segment 330, and the two ends of the rotating shaft 300 are rotatably connected to the first blind hole and the second blind hole through the first shaft segment 310 and the third shaft segment 330 respectively.

[0048] Specifically, the rotating shaft 300 is a cylindrical shaft, and the first shaft section 310, the second shaft section 320 and the third shaft section 330 are integrally formed into the rotating shaft 300. The central axes of the first shaft section 310, the second shaft section 320 and the third shaft section 330 coincide, that is, the three are on the same straight line. The first shaft section 310 and the third shaft section 330 are symmetrically distributed relative to the second shaft section 320.

[0049] It is not difficult to understand that, since the outer diameter of the second shaft segment 320 is greater than the outer diameters of the first shaft segment 310 and the third shaft segment 330, there is a sudden change in the outer diameter at the connection between the first shaft segment 310 and the second shaft segment 320, which enables an annular step surface extending from the side wall of the first shaft segment 310 to be formed on the second shaft segment 320. In this way, when one end of the rotating shaft 300 is rotatably connected to the first blind hole on the main frame 100 through the first shaft segment 310, the annular step surface forms a limit to the rotating shaft 300 along the axial direction of the rotating shaft 300.

[0050] Similarly, the annular step surface formed on the second shaft segment 320 and extending from the side wall of the third shaft segment 330 constitutes an axial limiting structure between the other end of the rotating shaft 300 and the cover frame 210 .

[0051] It is not difficult to understand that two annular step surfaces for axially limiting the rotating shaft 300 can be formed on the second shaft section 320 of the rotating shaft 300, so as to realize the axial limitation of the rotating shaft 300 as a whole, and prevent the rotating shaft 300 from axially deviating or moving when the rotating shaft 300 drives the cover frame 210 to rotate and open around the main frame 100, thereby preventing the cover frame 210 from contacting and rubbing with the main frame 100 when rotating and opening, and further improving the stability of the overall rotation of the cover assembly 200.

[0052] In addition, in order to improve the smoothness of rotation of the cover assembly 200, the first shaft segment 310 on the rotating shaft 300 can be installed in the first blind hole through a bearing. Similarly, the third shaft segment 330 of the rotating shaft 300 can also be installed in the second blind hole through a bearing. In this way, the rotating shaft 300 can be prevented from getting stuck during rotation, thereby improving the smoothness of the overall rotation of the cover assembly 200.

[0053] Of course, in order to enable the cover assembly 200 to rotate relative to the main frame 100 and stably stay at any angle, the rotating shaft 300 can also be configured as a damping shaft.

[0054] See also Figure 2 and Figure 5 In some embodiments of the present application, the main frame 100 includes four side beams 120 , and the four side beams 120 are sequentially connected end to end to enclose and form the first opening 110 .

[0055] Specifically, the four side beams 120 are all straight beams to enclose and form a rectangular first opening 110. Two adjacent side beams 120 are detachably connected. In this way, the overall disassembly and assembly of the main frame 100 and the disassembly and assembly and replacement of a single side beam 120 can be facilitated.

[0056] Moreover, the main frame 100 can also be disassembled into four independent side beams 120, which is convenient for the storage and transportation of batches of main frames 100 and door panel structures.

[0057] Further, see Figure 2 and Figure 5 The side beam 120 is provided with a plurality of connection holes 121 along its length direction and / or width direction. The connection holes 121 on two adjacent side beams 120 can be aligned with each other and can be detachably connected via fasteners 130 .

[0058] Specifically, the connection hole 121 is a threaded hole, and correspondingly, the fastener 130 is a screw or bolt that matches the threaded hole. In this way, the connection position of two adjacent side beams 120 can be adjusted in the length direction and / or width direction, thereby adjusting the size of the first opening 110 to adapt to the openings of weak current boxes of different sizes, thereby improving the compatibility and adaptability of the entire door panel structure.

[0059] See also Figure 2 In some embodiments of the present application, a snap-fitting groove 140 for snapping the cover frame 210 is formed on the circumferential edge of the main frame 100 , and the snap-fitting groove 140 surrounds the first through opening 110 .

[0060] Specifically, the two opposite side beams 120 on the main frame 100 are constructed as L-shaped, and the other two opposite side beams 120 are constructed as flat plates. In this way, the two L-shaped and two flat plate-shaped side beams 120 are connected end to end to form an annular snap-fit ​​groove 140, which surrounds the first opening 110.

[0061] In this way, when the cover plate frame 210 drives the glass panel 220 thereon to rotate and cover the first opening 110, the edge of the cover plate frame 210 can be buckled in the buckling groove 140, so that the cover plate frame 210 is limited by the buckling groove 140, effectively preventing the cover plate assembly 200 from being offset or misaligned to the left or right or up and down when the cover plate assembly 200 covers the first opening 110 as a whole, ensuring that the glass panel 220 completely closes the first opening 110. At the same time, the top surface of the cover plate assembly 200 can be flush with the top surface of the main frame 100, thereby improving the overall appearance of the door panel structure.

[0062] In some embodiments of the present application, the main frame 100 and / or the cover frame 210 are constructed as aluminum profiles, which reduces the probability of the main frame 100 and / or the cover frame 210 being corroded by water vapor, improves the overall appearance of the door panel structure, and indirectly improves the safety performance of the low-voltage box.

[0063] In addition, the embodiment of the present application further provides a weak current box, which includes the door panel structure described in any of the above embodiments. Specifically, the main frame 100 of the door panel structure can be detachably installed at the box opening position of the weak current box by screws, bolts, buckles and other installable parts.

[0064] It is not difficult to understand that the weak current box of the embodiment of the present application, since it is equipped with the above-mentioned door panel structure, also has the same technical effect brought by the door panel structure, that is, the box opening of the weak current box is closed by covering the first opening 110 with the glass panel 220. During the use and operation of the weak current box, the glass structure of the glass panel 220 will not generate an interfering magnetic field, that is, the glass panel 220 will not interfere with the signal transmission of the electrical components in the weak current box. In this way, the interference caused by the door panel structure to the signal transmission of the electrical components in the weak current box is greatly reduced, thereby ensuring the normal use and operation of the weak current box and effectively improving the performance of the weak current box.

[0065] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
