[0023] 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.

[0024] Example 1: Please refer to Figure 1-Figure 4 An electrical junction box with an anti-dismantling alarm function comprises an electrical junction box 1, wherein the electrical junction box 1 comprises a box body 11 and a box slot 12 opened on the front end surface of the box body 11, an inner slot 111 is opened inside the main body of the box body 11 and inside the box slot 12, a side slot 113 is opened on the outside of the box body 11, a box cover 15 is slidably installed inside the inner slot 111 and the side slot 113, and an alarm component 13 is installed inside the box body 11 and on a side away from the side slot 113.

[0025] The alarm component 13 includes an installation box 131 and an internal frame 133 installed inside the installation box 131 . An alarm 134 is installed in the middle of the internal frame 133 . A single chip computer 135 is installed at the top of the internal frame 133 and on one side of the alarm 134 .

[0026] A mounting hole 114 is provided inside the box body 11 and on one side of the inner groove 111, and a pressure sensor A115 is installed inside the mounting hole 114. A rear tube 136 is installed through the rear end of the box body 11, and a pressure sensor B137 is installed inside the rear tube 136. The detection end of the pressure sensor B137 is located at the rear end of the box body 11, and the rear tube 136, the pressure sensor A115 and the single-chip computer 135 are electrically connected.

[0027] A bottom groove 116 is provided at the bottom end of the box body 11 and on the lower side of the installation box 131. A waterproof membrane 117 and a dustproof net 118 are installed inside the bottom groove 116, and the dustproof net 118 is located below the waterproof membrane 117. The waterproof membrane 117 is provided to waterproof the interior of the box body 11, and the dustproof net 118 is provided to dustproof the waterproof membrane 117.

[0028] In this embodiment: when the box body 11 is installed on the wall, the detection end of the rear tube 136 inside the pressure sensor B137 contacts the wall, and when the box cover 15 is inside the inner groove 111, one end of the box cover 15 applies pressure to the detection end of the pressure sensor A115, and the pressure data detected by the rear tube 136 and the pressure sensor A115 are transmitted to the single-chip computer 135 for processing. When the data changes greatly, the single-chip computer 135 controls the alarm 134 to operate, and the sound is transmitted to the outside through the bottom groove 116. Since the alarm 134 is inside the box body 11, the damage to the alarm 134 by thieves is reduced. The waterproof membrane 117 is set to block water to prevent thieves from maliciously destroying the performance of the alarm 134. The dustproof net 118 is set to perform dustproof treatment on the waterproof membrane 117 to protect the alarm 134 and the single-chip computer 135.

[0029] Example 2: Please refer to Figure 2-Figure 4 A rubber frame 112 is installed on the inner wall of the box body 11 and at the rear end of the inner groove 111. A threaded hole A119 is opened on the front end surface of the box body 11 and on one side of the box groove 12. When the box cover 15 blocks the interior of the inner groove 111, the rubber frame 112 is provided to seal between the box body 11 and the box cover 15.

[0030] The box cover 15 includes an L-shaped push plate 151 and a sealing strip 154 ​​installed inside the L-shaped push plate 151 . The sealing strip 154 ​​is located inside the side groove 113 to perform sealing between the inside of the side groove 113 and the L-shaped push plate 151 .

[0031] A push block 153 is installed on the inner side of the L-shaped push plate 151, and the bottom end of the push block 153 contacts the inner bottom end of the box groove 12. A rotating plate 132 is hingedly installed on one side of the inner lower end of the installation box 131. When the push block 153 moves with the L-shaped push plate 151, the push block 153 rotates the rotating plate 132 back to the inside of the installation box 131 to insulate the parts inside the installation box 131.

[0032] A threaded hole B152 is formed on one side of the L-shaped push plate 151 , and the threaded hole B152 is aligned with the threaded hole A119 . The internal threads of the threaded hole B152 and the threaded hole A119 are connected with bolts 14 to fix the position of the box cover 15 .

[0033] In this embodiment: the L-shaped push plate 151 is moved from one side of the inner groove 111 to perform daily maintenance on the parts inside the box body 11 and the alarm component 13. When the L-shaped push plate 151 moves toward one side of the alarm component 13, the push block 153 pushes the rotating plate 132 to flip toward one side of the installation box 131, and the rotating plate 132 moves into the interior of the installation box 131 to block the heat generated during the operation of the box body 11. At the same time, the heat generated by the operation of the single-chip microcomputer 135 and the alarm 134 can be dissipated through the bottom groove 116, the waterproof membrane 117 and the dustproof net 118. When one end of the L-shaped push plate 151 contacts the inner wall of the inner groove 111, the bolt 14 can be threadedly connected to the inside of the threaded hole A119 and the threaded hole B152. The sealing strip 154 ​​is squeezed by the box body 11 and deformed. The rubber frame 112 seals the box cover 15 and the box body 11 to fix the box cover 15 and the box body 11.

[0034] Working principle: When the box body 11 is installed on the wall, the detection end of the rear tube 136 inside the pressure sensor B137 contacts the wall, and one end of the box cover 15 applies pressure to the detection end of the pressure sensor A115. The pressure data detected by the rear tube 136 and the pressure sensor A115 are transmitted to the single-chip computer 135 for processing. When the data changes greatly, the single-chip computer 135 controls the alarm 134 to operate, and the sound is transmitted to the outside through the bottom groove 116. Since the alarm 134 is inside the box body 11, the damage to the alarm 134 by thieves is reduced. When one end of the L-shaped push plate 151 contacts the inner wall of the inner groove 111, the bolt 14 can be threadedly connected to the inside of the threaded hole A119 and the threaded hole B152. The sealing strip 154 ​​is squeezed by the box body 11 and deformed. The rubber frame 112 seals the box cover 15 and the box body 11 to fix the box cover 15 and the box body 11.
