DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0022] A power distribution cabinet for convenient electronic component maintenance, comprising a cabinet body 1 and a plurality of electronic components 2, wherein a C-shaped connecting sleeve 21 is fixedly installed on the rear surface of each electronic component 2, four limiting rails 11 are symmetrically fixedly installed on the inner side wall of the cabinet body 1, a movable frame 3 is slidably installed between the four limiting rails 11, a plurality of upper connecting plates 4 and lower connecting plates 5 with adjustable installation positions are installed in the movable frame 3, the C-shaped connecting sleeve 21 is fixedly installed between the corresponding upper connecting plate 4 and the corresponding lower connecting plate 5, and a positioning mechanism is installed between the movable frame 3 and the cabinet body 1;

[0023] It should be noted that, combined with Figure 1 As shown, the positioning mechanism includes four positioning sleeves 12 and U-shaped pins 34. The four positioning sleeves 12 are symmetrically fixedly installed at the front and rear ends of the bottom of the inner cavity of the cabinet 1. The lower end of the movable frame 3 is symmetrically provided with two through openings 33. The bottom end of the U-shaped pin 34 passes through the through opening 33 and is inserted into the corresponding positioning sleeve 12.

[0024] When inspecting the electronic component 2 in the cabinet 1, first pull out the U-shaped pin 34 from the through-opening 33 to disengage the U-shaped pin 34 from the connection with the rear end positioning sleeve 12, and then manually pull the movable frame 3 toward the cabinet door of the cabinet 1. After the movable frame 3 moves to the cabinet door, the position of the through-opening 33 is perpendicular to the front end positioning sleeve 12. After that, the bottom end of the U-shaped pin 34 is inserted through the through-opening 33 into the front end positioning sleeve 12 to fix the position of the movable frame 3 again. At this time, the inspection function of the electronic component 2 can have a larger operating space. Compared with the distribution cabinet in the prior art, it can be more convenient to inspect the electronic component 2.

[0025] In addition, if Figure 3 As shown, an L-shaped mounting groove 31 is relatively penetrated through the inner wall of the movable frame 3, and slots 32 are equidistantly provided in the L-shaped mounting groove 31. Mounting holes 321 are provided at positions opposite to the slots 32 on the front surface of the movable frame 3. When installing the upper connecting plate 4 and the lower connecting plate 5, the end portions of the upper connecting plate 4 and the lower connecting plate 5 are respectively clamped in the corresponding slots 32. After installing fixing bolts in the corresponding mounting holes 321, the upper connecting plate 4 and the lower connecting plate 5 can be fixed. Before installation, the ends of the upper connecting plate 4 and the lower connecting plate 5 can be installed in the corresponding slots 32 according to the height of the electronic components, and the distance between the upper connecting plate 4 and the lower connecting plate 5 can be appropriately adjusted.

[0026] It is worth noting that if Figure 2 As shown, the upper and lower ends of the C-shaped connecting sleeve 21 are penetrated with locking openings 211; Figure 4 As shown, a plurality of blocks 41 are fixedly installed on the upper surface of the upper connecting plate 4 at equal intervals, and the upper locking opening 211 of the C-shaped connecting sleeve 21 is sleeved on the corresponding block 41; Figure 5 As shown, a plurality of grooves 51 are equidistantly formed on the lower surface of the lower connecting plate 5, and a U-shaped operating rod 52 is slidably installed in each groove 51, and a cross block 53 is fixedly installed on the lower surface of the U-shaped operating rod 52, and the cross block 53 is clamped in the lower end locking opening 211 of the corresponding C-shaped connecting sleeve 21, and the cross block 53 is slidably connected to the corresponding groove 51, and an extrusion spring 54 is fixedly installed between the cross block 53 and the corresponding groove 51;

[0027] When installing the electronic component 2 between the upper connecting plate 4 and the lower connecting plate 5, first lift up the U-shaped operating rod 52 at the corresponding position, use the U-shaped operating rod 52 to drive the cross block 53 to move up, and drive the extrusion spring 54 to compress, so as to vacate the installation space at the lower end of the C-shaped connecting sleeve 21, and then first set the upper end locking mouth 211 of the C-shaped connecting sleeve 21 on the corresponding card block 41, and then the rear surface of the C-shaped connecting sleeve 21 is in contact with the front surfaces of the upper connecting plate 4 and the lower connecting plate 5, and at this time, the lower end of the C-shaped connecting sleeve 21 is in contact with the upper connecting plate 4 and the lower connecting plate 5. The end locking opening 211 is located directly below the cross block 53. After the hand holding the U-shaped operating rod 52 is released, the extrusion spring 54 stretches and resets, driving the cross block 53 to move downward and insert into the lower end locking opening 211, thereby fixing the C-shaped connecting sleeve 21 between the upper connecting plate 4 and the lower connecting plate 5. At this time, the electronic component 2 is fixedly installed between the upper connecting plate 4 and the lower connecting plate 5. When the electronic component 2 needs to be disassembled and repaired, the reverse operation can be performed to remove it from between the upper connecting plate 4 and the lower connecting plate 5.

[0028] Finally, when pulling or pushing the movable frame 3 to move, in order to make the operation more labor-saving, as Figure 1 As shown, two directional wheels 35 are symmetrically fixedly installed on the lower surface of the movable frame 3. The directional wheels 35 are rollingly set at the bottom of the inner cavity of the cabinet 1. The directional wheels 35 can be used to lift and support the movable frame 3, which can save more effort when moving the movable frame 3.
