DETAILED DESCRIPTION

[0024] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] The outdoor power metering cabinet according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0026] like Figures 1 to 4 As shown, the outdoor power metering cabinet according to the embodiment of the present invention may include a cabinet body 100 , a mounting frame 200 and an electrical component 300 .

[0027] The front end of the cabinet 100 is open, and a cabinet door 101 that can be opened and closed is provided at the opening. The cabinet door 101 and the cabinet 100 are connected by a lock. Relevant staff can selectively use the lock with anti-theft function according to outdoor conditions.

[0028] Track racks 102 are provided on both sides of the bottom of the cabinet 100 along the opening direction, and a long cable duct 103 is provided between the two track racks 102 .

[0029] It should be noted that two cable ducts 103 can be provided, one of which serves as an input cable duct and the other as an output cable duct. By arranging the input and output cables separately, the space layout in the cabinet 100 is further optimized.

[0030] The mounting frame 200 can be movably set in the cabinet 100 and limited by a locking structure. Multiple cross arms 201 are set on both sides of the mounting frame 200 from top to bottom. The electrical components 300 are set on the cross arms 201, and the connecting wires of the electrical components 300 extend from the cable trough 103 to the outside of the cabinet 100.

[0031] It should be noted that the connecting wires of the electrical device 300 may be provided with a reserved length at the cable groove 103 to prevent the electrical device 300 and the connecting wires from being pulled when the mounting frame 200 is pulled outward, thereby preventing damage to the connecting wires or interfaces.

[0032] The bottom of the mounting frame 200 is provided with a roller 202 that matches the track frame 102. The roller 202 is connected to the track frame 102 in a rolling manner. Rotatable rotating arms 203 are provided on both sides of the bottom of the mounting frame 200. The ends of the rotating arms 203 elastically abut against the bottom of the inner wall of the cabinet 100.

[0033] It should be noted that when the mounting bracket 200 is pushed into the cabinet 100, the end of the rotating arm 203 elastically abuts against the inner wall of the cabinet 100. When the mounting bracket 200 is pulled out of the cabinet 100, the rotating arm 203 is elastically reset and pops out.

[0034] To clearly illustrate the above embodiment, in one embodiment of the present invention, Figure 5 As shown, one end of the rotating arm 203 is rotatably set at the bottom of the mounting frame 200 through a shaft connection 2031, and a limit block 2032 is set on the shaft connection 2031, a torsion spring 2033 is set on the rotating shaft of the rotating arm 203, and a rotatable rotating wheel 2034 is set at the other end of the rotating arm 203, wherein, after the mounting frame 200 is pulled outward, the rotating arm 203 is rotated to the limit block 2032 under the resetting action of the torsion spring 2033.

[0035] As a possible scenario, after the mounting frame 200 is pulled outward, the rotating arm 203 rotates to a vertical state, and the rotating wheel 2034 contacts the ground. Then, when the mounting frame 200 is pulled, the rotating wheel 2034 rolls on the ground to improve the stability of the moving mounting frame 200.

[0036] Specifically, if Figures 1 to 6 As shown, when the relevant staff is installing, repairing or disassembling the electrical device 300 , first, the relevant staff opens the locking structure and pulls the mounting frame 200 outward, and then the roller 202 rolls on the track frame 102 .

[0037] As the mounting bracket 200 moves outward, the end of the rotating arm 203 loses contact with the inner wall of the bottom of the cabinet 100, causing the torsion spring 2033 to reset and drive the rotating arm 203 to rotate to the limit block 2032. At this time, the rotating wheel 2034 is in contact with the ground. When the relevant staff pulls the mounting bracket 200, the entire rotating arm 203 provides stable support for the mounting bracket 200.

[0038] When most of the mounting frame 200 is pulled out of the cabinet 100, the relevant staff installs the electrical component 300 on the cross arm 201, or replaces the new electrical component 300, and pushes the mounting frame 200 back into the cabinet 100 after the installation or maintenance and disassembly is completed. Before pushing the mounting frame 200 back completely, the relevant staff rotates the rotating arm 203 upward so that the entire rotating arm 203 is completely inserted into the cabinet 100, and after pushing the mounting frame 200 back, the locking structure is locked again.

[0039] To further improve the stability of the mounting frame 200 during movement, Figure 2 As shown, slide rails 104 are provided on the inner walls on both sides of the cabinet 100, and a plurality of ball bearings 204 are embedded in sequence and equidistantly along the openings on both sides of the bottom of the mounting frame 200. The ball bearings 204 are connected to the slide rails 104 in a rolling manner. When the mounting frame 200 moves, the ball bearings 204 can roll along the track grooves of the slide rails 104, and a rolling contact method is adopted to provide support for the mounting frame 200, thereby reducing the resistance to movement.

[0040] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, the locking structure includes a blocking rod 205 and a card slot 105, wherein the blocking rod 205 is rotatably set on the mounting frame 200, and the card slot 105 is set on the bottom inner wall of the cabinet 100, and the blocking rod 205 can be rotated into the card slot 105.

[0041] As a possible scenario, a magnetic plate is provided in the card slot 105 , and a magnetic block is provided at the end of the blocking rod 205 . When the blocking rod 205 is rotated into the card slot 105 , the magnetic block is magnetically connected to the magnetic plate.

[0042] In order to facilitate relevant staff to move the mounting frame 200, a handle 206 for easy pushing and pulling is provided at the front end of the mounting frame 200.

[0043] In one embodiment of the present invention, Figure 2 As shown, a limiting column 106 is provided on the rear inner wall of the cabinet 100 . When the mounting frame 200 is pushed into the cabinet 100 , the locking structure limits the mounting frame 200 , and the limiting column 106 abuts against the rear end of the mounting frame 200 .

[0044] It should be noted that the limit column 106 can be a rubber column to prevent the mounting frame 200 from being pushed into the cabinet 100 too quickly, causing a collision, thereby causing the electrical component 300 to fall off or even be damaged. The provision of the rubber column can effectively reduce the impact.

[0045] To facilitate installation of the cabinet 100 , support columns 107 are respectively provided at the four corners of the bottom of the cabinet 100 .

[0046] As a possible scenario, the support column 107 includes a column, a screw and a base, wherein the column is arranged at the bottom of the cabinet 100, the screw is threadedly connected to the bottom of the column, and the base is rotatably arranged at the bottom of the screw. Relevant staff can adjust the length of the screw screwed into the column by rotating the rod, so that the height of the entire support column 107 can be fine-tuned to facilitate the adjustment of the flatness of the cabinet 100 according to different outdoor conditions.

[0047] In summary, according to the outdoor power metering cabinet of the embodiment of the present invention, the electrical device 300 is installed on the mounting frame 200, and the mounting frame 200 and the electrical device 300 can be pulled out from the cabinet body 100 by pulling, thereby increasing the operating space during installation and maintenance. In addition, through the setting of the rotating arm 203, the mounting frame 200 can be made more stable when pulled out.
