DETAILED DESCRIPTION

[0020] like Figure 1-Figure 8 As shown, an assembled distribution box according to an embodiment of the present invention comprises: a distribution box main body 9; A shielding plate 1 fixedly connected to the top of the distribution box body 9; A protective housing 18 fixedly connected to one side of the distribution box body 9; A hinge 19 fixedly connected to the front side of the protective housing 18; The bottom of the distribution box body 9 is fixedly connected to a bottom mounting cabinet body 16, a filter screen frame 21 is slidably connected to the lower part of one side of the bottom mounting cabinet body 16, a filter screen 14 is fixedly connected to the rear side of the filter screen frame 21, a filter box 15 is slidably connected to the upper part of one side of the bottom mounting cabinet body 16, a rack 43 is fixedly connected to one side of the filter box 15, a second vent 4 is fixedly connected to the top of the distribution box body 9, a first vent 3 is penetrated through the top of the second vent 4, the first vent 3 is slidably connected to the second vent 4, a fixed bracket 31 is fixedly connected to the middle part of the top of the second vent 4, a first connecting rod 30 is penetrated and rotatably connected between the inner sides of the two fixed brackets 31, a cover plate 2 is fixedly connected to the outer wall of the first connecting rod 30, and the cover plate 2 is connected to the first connecting rod 30. Corresponding to a vent 3, two ventilation fans 32 are fixedly connected to the inner side of the second vent 4, and the inner side of the distribution box main body 9 is slidably connected with equidistantly distributed sliders 12, and the inner sides of the sliders 12 are fixedly connected with a mounting frame 11, and the inner side of the mounting frame 11 is provided with equidistantly distributed positioning grooves 13, and one side of the positioning grooves 13 is relatively arranged to the other side, and a mounting box 27 is arranged between two relatively equal height positioning grooves 13, and a limit block 29 is fixedly connected to the side of the bottom of the distribution box main body 9 close to the mounting frame 11, and a threaded rod 28 is threadedly connected to the lower part of one side of the mounting frame 11, and the two ends of the threaded rod 28 are rotatably connected to the limit block 29 and the distribution box main body 9 respectively, and a lower vent 33 is provided on the side of the bottom of the distribution box main body 9 away from the mounting frame 11.

[0021] In this embodiment, when it is necessary to install components inside the distribution box body 9, the mounting frame 11 is first moved to the front side of the inside of the distribution box body 9 through the cooperation of the threaded rod 28 and the mounting frame 11, so that the staff can install the components on the mounting frame 11 conveniently, thereby improving the flexibility and practicality of the installation of the distribution cabinet. When it is necessary to filter and replace the air inside the distribution box body 9, the internal air of the distribution box body 9 is first driven to flow by turning on the ventilation fan 32, the air is drawn into the external environment, and fresh air is sucked in from the bottom to complete the air replacement. The slider 12 can strengthen the structure of the mounting frame 11, and the stability of the movement of the mounting frame 11 can be improved under the action of the slider 12.

[0022] like Figure 3 and Figure 4 As shown, the first motor 17 is fixedly connected to one side of the protective shell 18, and the output end of the first motor 17 is fixedly connected to the first connecting rod 30, one end of the first connecting rod 30 is fixedly connected to the active bevel gear 22, and one side of the distribution box body 9 is fixedly connected to equidistantly distributed fixed blocks 25, the fixed blocks 25 have up and down through holes, the second connecting rod 24 passes through the through holes, and the fixed block 25 and the second connecting rod 24 can rotate relative to each other.

[0023] In this embodiment, the first motor 17 drives the first connecting rod 30 to rotate, and the first connecting rod 30 further drives the connected cover plate 2 to rotate, wherein the relative displacement of the second connecting rod 24 is limited by the fixing block 25 to avoid displacement.

[0024] like Figure 3 and Figure 4 As shown, the upper end of the second connecting rod 24 is fixedly connected with a driven bevel gear 23 , and the driven bevel gear 23 is meshingly connected with the driving bevel gear 22 . The lower end of the second connecting rod 24 is fixedly connected with a gear 26 , and the gear 26 is meshingly connected with the rack 43 .

[0025] In this embodiment, the power of the first motor 17 is transmitted through the meshing connection between the active bevel gear 22 and the driven bevel gear 23, and the power is further transmitted to the gear 26 through the second connecting rod 24, and the rack 43 is driven to move forward and backward through the gear 26, further driving the filter box 15 to move.

[0026] like Figure 5 and Figure 6 As shown, a limit rod 41 is fixedly connected to the middle part of the inner side of the installation box 27, and the left and right ends of the limit rod 41 are slidably connected to the limit block 40, and the limit block 40 is slidably connected to the installation box 27, and the limit block 40 cooperates with the positioning groove 13. A reset spring 42 is sleeved in the middle part of the limit rod 41, and the two ends of the reset spring 42 are fixedly connected to the two limit blocks 40 respectively.

[0027] In this embodiment, when the limit block 40 is squeezed toward the middle, the reset spring 42 is compressed by the limit block 40. When the installation box 27 is placed in a suitable position and the limit block 40 is released, the reaction force of the reset spring 42 pushes the two limit blocks 40 to reset. The limit rod 41 not only limits the movement direction and position of the limit block 40, but also limits the position of the reset spring 42 to avoid deflection and displacement after compression.

[0028] like Figure 6 As shown, an arc-shaped toggle rod 38 is fixedly connected to the upper part of one side of the limit block 40 , and two arc-shaped toggle rods 38 on adjacent sides correspond to each other, and a mounting plate 39 is fixedly connected to one side of the mounting box 27 .

[0029] In this embodiment, when the installation box 27 needs to be installed or removed, the arc-shaped toggle rod 38 needs to be used to drive the limit blocks 40 at both ends to move. By releasing the restriction of the limit blocks 40 on the mounting frame 11, the installation box 27 is removed and the components are installed through the mounting plate 39.

[0030] like Figure 5As shown, the front end of the threaded rod 28 is fixedly connected to a driven flat gear 36, the front bottom of the distribution box body 9 is fixedly connected to a second motor 34, the output end of the second motor 34 is fixedly connected to a driving flat gear 37, and the driving flat gear 37 is meshingly connected with the driven flat gear 36.

[0031] In this embodiment, when it is necessary to drive the mounting frame 11 to move, the second motor 34 drives the driving flat gear 37 to move, and the power of the driving flat gear 37 is further transmitted through the driven flat gear 36 to drive the threaded rod 28 to rotate, and in cooperation with the mounting frame 11, the mounting frame 11 is driven to move forward and backward.

[0032] like Figure 5 As shown, a plurality of traveling wheels 35 are fixedly connected to the outer side of the mounting frame 11 , and the traveling wheels 35 are rollingly arranged in the slide rails 10 , and the slide rails 10 are fixedly connected to the distribution box body 9 .

[0033] In this embodiment, during the movement of the mounting frame 11, the traveling wheel 35 cooperates with the slide rail 10 to make the movement of the mounting frame 11 smoother and more stable, and the mutual cooperation between the traveling wheel 35 and the slide rail 10 also has a certain limiting effect to avoid possible deflection of the mounting frame 11.

[0034] like Figure 1 and Figure 2 As shown, a distribution cabinet door panel 7 is fixedly connected between the other ends of the hinge 19, an observation window 6 is provided on the upper front portion of the distribution cabinet door panel 7, a handle 20 is fixedly connected to the lower front portion of the distribution cabinet door panel 7, humidity sensors 5 are fixedly connected to the upper and lower sides of the rear side of the distribution cabinet door panel 7, and a controller 8 is fixedly connected to the lower rear side of the distribution cabinet door panel 7.

[0035] In this embodiment, the observation window 6 can facilitate the staff to observe the situation inside the distribution box body 9, and the humidity sensor 5 can monitor the humidity of the surrounding environment. The humidity level of the internal environment of the distribution box body 9 can be monitored by the humidity sensor 5, and the signal can be sent to the controller 8, which controls and coordinates the operation of various components.

[0036] Working principle: When using the distribution box, the distribution cabinet door plate 7 is opened, and the active flat gear 37 is driven to rotate by starting the second motor 34, and then the threaded rod 28 is driven to rotate through the transmission of the driven flat gear 36, and the mounting frame 11 is further driven to move forward by the mutual cooperation of the threaded rod 28 and the mounting frame 11. Then, according to actual needs and the size and arrangement of the installed components, a suitable number of mounting boxes 27 are installed on the mounting frame 11. First, the two limit blocks 40 are driven to move closer to the middle by squeezing the arc-shaped toggle rod 38 toward the middle, and then the mounting box 27 together with the limit blocks 40 are placed between the positioning grooves 13 at the appropriate position, and then the arc-shaped toggle rod 38 is released, and the two limit blocks 40 are driven to engage with the positioning grooves 13 under the reaction of the reset spring 42, and then the components are installed on the mounting frame 11 in sequence with the assistance of the mounting plate 39, and then the mounting frame 11 is brought back to the inner rear side of the distribution box body 9 by starting the second motor 34 again, and then the distribution cabinet door plate 7 is closed. Under normal circumstances, heat is exchanged with the external environment through the lower vent 33 to discharge the heat generated by the components. The humidity of the internal environment of the distribution box body 9 is monitored by the humidity sensor 5. When the air humidity increases and the humidity exceeds the threshold, the humidity sensor 5 first sends a signal to the controller 8, and then the controller 8 controls and turns on the first motor 17. Under the action of the first motor 17, the first connecting rod 30 is driven to rotate, and then the cover plate 2 is turned upward. The first connecting rod 30 rotates while driving the active bevel gear 22 to rotate, and then cooperates with the conduction of the driven bevel gear 23 to drive the second connecting rod 24 to rotate. The gear 26 rotates with the second connecting rod 24, and further cooperates with the rack 43 to drive the rack 43 and the filter box 15 to move backward. Then, the ventilation fan 32 is turned on to drive the air flow inside the distribution box body 9, and the air with high humidity inside is extracted. The external air passes through the filter box 15 to filter out the moisture in the air, so as to avoid the moisture in the air affecting the normal operation of the power distribution.
