[0013] Preferably, a notch is provided at the bottom of the side wall of the box body, a control knob is arranged in the notch, a control column is fixed on the top of the control knob, and the end of the control column vertically penetrates into the switching window and is fixedly connected to the bottom end of the rotating column.

[0014] Preferably, a shielding plate is attached to the top open end of the exit frame, and the bottom end of the shielding plate is hingedly connected to the fixing seat.

[0015] Preferably, a movable slit is vertically opened on the inner side wall of the fixed seat, and a movable block fixedly connected to the inner side wall of the movable seat is slidably arranged in the movable slit.

[0016] Compared with the prior art, the advantages of the present invention are:

[0018] (2) By setting the conversion component, when it is necessary to replace the moisture absorption plate built into the box body, it is only necessary to use the conversion component to swap the positions of the assembly frames on both sides of the box body. In this way, the spare moisture absorption plate originally located on the outside of the box body can be transferred to the inside of the box body, thereby achieving the effect of quickly replacing the moisture absorption plate originally built into the box body. There is no need to manually loosen multiple sets of bolts and remove the box cover, which effectively improves the manual replacement speed of the moisture absorption plate and enhances practicality.

[0019] (3) By setting up the sealing mechanism, the switch window opening can be effectively shielded without interfering with the overall rotation of the switch plate and the assembly frame, thereby preventing a large amount of dust from entering the inner side of the box body through the switch window during the rotation of the switch plate, thereby ensuring good dustproof sealing inside the box body and maintaining the service life of the built-in wiring parts of the box body.

[0020] (4) Through the arrangement of the gas-filling component, the sponge block and the airbag, when the movable seat is pushed up, the gas inside the airbag is absorbed by the gas-filling component, and then the airbag and the sponge block shrink as a whole, so as to avoid excessive friction and contact between the moisture absorbing plate and the sponge block when the moisture absorbing plate passes through the inner side of the exit frame, reduce movement obstacles, and allow the moisture absorbing plate to pass through the exit frame smoothly. On the contrary, when the moisture absorbing plate is replaced and the movable seat is released, so that the movable seat automatically resets under gravity, the movable seat compresses the gas-filling component, so that the gas-filling component injects gas into the inner side of the airbag through the shunt pipe, and then expands the airbag and the sponge block as a whole, so that when the moisture absorbing plate is inserted into the inner side of the exit frame, the sponge blocks on both sides of the exit frame are respectively close to the two sides of the moisture absorbing plate, and then the dust and stains on both sides of the moisture absorbing plate are effectively scraped and cleaned, so as to achieve a self-cleaning effect on the surface of the moisture absorbing plate and avoid dust and stains affecting the moisture absorption of the moisture absorbing plate.

[0028] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0029] Reference Figure 1-5 As shown, a novel moisture-proof prefabricated electrical junction box comprises a box body 1 with an open top, a box cover 2 detachably mounted on the open end of the box body 1 by screws, and a plurality of threading holes equidistantly opened on the side wall of the box body 1, and also comprises a moisture-proof mechanism for preventing moisture from affecting the connecting parts inside the box body 1;

[0030] The moisture-proof mechanism comprises two sets of assembly frames 6 symmetrically arranged on both sides of the box body 1 and a moisture-absorbing plate 3 slidably inserted into the inner side of the assembly frame 6;

[0031] By disposing the moisture absorbing plate 3 and utilizing the moisture absorption property of the moisture absorbing plate 3 , the moisture absorbing plate 3 inside the box body 1 can effectively absorb moisture in the humid air inside the box body 1 , so as to keep the air inside the box body 1 dry, thereby preventing the internal parts of the box body 1 from getting damp.

[0032] As can be seen from the above structure, the pre-connection box is a simple box-shaped structure, mainly composed of a box body 1 and a box cover 2, and the box cover 2 is fastened to the opening of the box body 1 by screws. As a result, when manually disassembling and assembling the moisture absorbing plate 3, it is necessary to loosen multiple screws on the box cover 2 one by one in advance, remove the box cover 2, and then replace the moisture absorbing plate 3 from the inside of the box body 1. The actual operation is time-consuming and labor-intensive, and the efficiency is poor;

[0033] Further, refer to Figure 3 As shown, it is worth noting that a switching window 4 is provided through the inner wall of the box body 1, the switching window 4 is located between the two sets of assembly racks 6, and a conversion component for switching the positions of the two sets of assembly racks 6 is provided in the switching window 4;

[0034] By setting the conversion component, when it is necessary to replace the built-in moisture absorbing plate 3 of the box body 1, it is only necessary to use the conversion component to exchange the positions of the assembly frames 6 on the inner and outer sides of the box body 1, so that the spare moisture absorbing plate 3 originally located on the outer side of the box body 1 can be transferred to the inner side of the box body 1, thereby achieving the effect of rapid replacement of the original built-in moisture absorbing plate 3 of the box body 1, without the need for tedious manual loosening of multiple sets of bolts and disassembly of the box cover 2, which effectively improves the manual replacement speed of the moisture absorbing plate 3 and enhances practicality.

[0035] Further, refer to Figure 3 As shown, it is worth noting that the conversion component includes a rotating column 7 vertically rotatably arranged between the inner walls at both ends of the switching window 4 and a switching rotating plate 5 tightly sleeved on the rod of the rotating column 7, the side wall of the switching rotating plate 5 is in contact with the inner wall of the switching window 4, and two sets of assembly frames 6 are respectively fixed on the two sides of the switching rotating plate 5;

[0036] A notch is provided at the bottom of the side wall of the box body 1, and a control twist block 9 is provided in the notch. A control column 8 is fixed to the top of the control twist block 9, and the end of the control column 8 vertically penetrates into the switching window 4 and is fixedly connected to the bottom end of the rotating column 7;

[0037] The simple knob controls the twist block 9, and the control column 8 can cause the rotating column 7 and the switching rotating plate 5 to rotate 180 degrees as a whole, so that the two sides of the switching rotating plate 5 can be exchanged, and the two sets of assembly frames 6 and moisture absorption plates 3 can be replaced.

[0038] Although the above embodiment achieves the effect of rapid replacement of the moisture absorption plate 3 built into the box body 1 by means of the conversion component, in practice, the box body 1 is widely used in home decoration, and a large amount of dust and impurities are often generated during the decoration process. In the process of rotating the switching plate 5 to replace the two sets of moisture absorption plates 3, the inside of the switching window 4 is wide open, and dust and impurities can easily enter the box body 1 through the gap inside the switching window 4, thereby contaminating the wiring parts built into the box body 1, affecting the conductivity and use effect of the wiring parts;

[0039] For this purpose, refer to Figure 3 As shown, it is worth noting that it also includes a sealing mechanism for improving the sealing performance of the interior of the box body 1, the sealing mechanism is a box-shaped structure with one side open, and the open side of the sealing mechanism corresponds to the switching window 4;

[0040] By setting the sealing mechanism, the opening of the switching window 4 can be effectively shielded without interfering with the overall rotation of the switching turn plate 5 and the assembly frame 6, thereby preventing a large amount of dust from entering the inner side of the box body 1 through the switching window 4 during the rotation of the switching turn plate 5, thereby ensuring a good dustproof sealing inside the box body 1 and maintaining the service life of the built-in wiring parts of the box body 1.

[0041] Further, refer to Figure 3 and Figure 4As shown, it is worth noting that the sealing mechanism is mainly composed of a fixed seat 10 and a movable seat 11 in a semi-box shape. One side of the fixed seat 10 is open and fixed on the side wall of the box body 1, and one side of the movable seat 11 is open and slides on the side wall of the box body 1. The bottom end of the fixed seat 10 is open and has a U-shaped slideway that matches the movable seat 11, and the movable seat 11 slides in the U-shaped slideway.

[0042] An exit frame 13 corresponding to the moisture absorption plate 3 is fixedly penetrated in the inner wall of the top of the fixed seat 10, an extrusion column 12 is vertically fixed on the inner wall of the bottom end of the movable seat 11, and a punching hole adapted to the extrusion column 12 is penetrated at the bottom end of the assembly frame 6;

[0043] After the switching rotating plate 5 is rotated and the moisture absorption plate 3 originally built into the box body 1 is transferred to the outside of the box body 1, the movable seat 11 is pushed up immediately to make the movable seat 11 slide in the U-shaped slide. During this process, the extrusion column 12 moves up synchronously with the movable seat 11, and penetrates into the punch hole to push the moisture absorption plate 3 up, so that the moisture absorption plate 3 is forced to slide up and pass through the exit frame 13, thereby facilitating manual removal.

[0044] On the contrary, the moisture absorbing plate 3 only needs to be aligned and inserted from the exit frame 13 , and the moisture absorbing plate 3 can be inserted into the inner side of the fixing seat 10 and slidably inserted on the assembly rack 6 , thereby realizing the assembly of the moisture absorbing plate 3 on the assembly rack 6 .

[0045] Further, refer to Figure 3 and Figure 4 As shown, it is worth noting that a shielding plate 14 is attached to the top open end of the exit frame 13, and the bottom end of the shielding plate 14 is hingedly connected to the fixing seat 10;

[0046] By setting the shielding plate 14, when the movable seat 11 is pushed upward to allow the moisture absorbing plate 3 to pass upward from the exit frame 13, the moisture absorbing plate 3 can simultaneously squeeze the shielding plate 14, so that it is flipped to one side under the action of the hinge, thereby facilitating the moisture absorbing plate 3 to pass out;

[0047] On the contrary, after the moisture absorbing plate 3 is inserted from the exit frame 13 to the assembly frame 6, the exit frame 13 is flipped over to close the opening of the exit frame 13 again, so that the internal sealing of the sealing mechanism composed of the fixed seat 10 and the movable seat 11 can be ensured.

[0048] Further, refer to Figure 3 and Figure 5 As shown, it is worth noting that a movable slit 22 is vertically opened on the inner side wall of the fixed seat 10, and a movable block 23 fixedly connected to the inner side wall of the movable seat 11 is slidably arranged in the movable slit 22;

[0049] Through the arrangement of the movable seam 22 and the movable block 23, when the movable seat 11 is pushed up, the movable block 23 synchronizes the movable seat 11 to slide inside the movable seam 22, and then the movable block 23 cooperates with the movable seam 22 to effectively limit the moving trajectory of the movable seat 11, so that the movable seat 11 can only be slid in the U-shaped slide all the time, thereby preventing the movable seat 11 from detaching from the U-shaped slide under gravity.

[0050] In addition, refer to Figure 1-5 As shown, it is worth noting that sponge blocks 15 are glued on the inner walls of both sides of the exit frame 13, a cavity is provided inside the sponge block 15, and an air bag 16 is provided in the cavity. A Y-shaped shunt pipe 17 is provided on the rear side of the exit frame 13, and two ends of one side of the shunt pipe 17 are respectively inserted into the two air bags 16, and an air filling component is provided in the fixed seat 10 to cooperate with the movable seat 11 for injecting air into the shunt pipe 17;

[0051] When the hygroscopic plate 3 is inserted into the inner side of the exit frame 13, the sponge blocks 15 on both sides of the exit frame 13 are respectively pressed against the two sides of the hygroscopic plate 3, thereby effectively cleaning the dust and stains on both sides of the hygroscopic plate 3, achieving the self-cleaning effect of the surface of the hygroscopic plate 3, and preventing the dust and stains from affecting the hygroscopic property of the hygroscopic plate 3.

[0052] Further, refer to Figure 1-5 As shown, it is worth noting that the gas-filling component includes two counterweight plates 19 symmetrically distributed on the inner wall of the fixed seat 10 and an air bag 20 fixed between the two counterweight plates 19, wherein the upper counterweight plate 19 is fixedly connected to the movable block 23, and the lower counterweight plate 19 is vertically fixed to the inner wall of the fixed seat 10, and a vent pipe 21 is provided at the bottom of the lower counterweight plate 19, one end of the vent pipe 21 is fixedly inserted into the air bag 20, and the other end of the vent pipe 21 vertically passes through the fixed seat 10 upwards and is fixedly connected to the shunt pipe 17 by an air guide pipe 18;

[0053] When the movable seat 11 is pushed upward, the movable block 23 can synchronously carry the upper counterweight plate 19 to slide upward, stretching the airbag 20, so that negative pressure is formed inside the airbag 20, and then the ventilating tube 21 can synchronously suck the air inside the two airbags 16 through the air guide tube 18 and the shunt tube 17, so that the two airbags 16 and the sponge block 15 are completely contracted;

[0054] On the contrary, when the movable seat 11 is released, the movable seat 11 automatically returns to its original position under gravity, and acts on the upper counterweight plate 19 to slide down and compress the airbag 20, so that the gas inside the airbag 20 is compressed and passes into the two airbags 16 through the ventilation pipe 21, the air guide pipe 18 and the shunt pipe 17, thereby causing the two airbags 16 and the sponge block 15 to expand as a whole.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention.
