DETAILED DESCRIPTION

[0034] The following will be described in detail in combination with the accompanying Figures 1-5 The application will be further described in detail.

[0035] The embodiment discloses a modular anti-theft electric energy metering box. Referring to Figure 1 and Figure 2The utility model relates to a kind of modularized anti-theft electric energy metering box, including box 1 and box door 2, box 1 is set with multiple containing grooves 11, containing groove 11 is placed for electrical component.The shell can be formed by injection molding with any one of PC+ABS, PC+ASA gold-containing plastic, PP+LGF (long glass fiber reinforced polypropylene);Or high-performance SMC composite material moulding / stainless steel material machining welding forming.

[0036] Referring to Figure 1 And Figure 2 Containing groove 11 is fixedly connected with support plate 12, support plate 12 is bolted with multiple electric energy meters 13, and multiple electric energy meters 13 and support plate 12 form electric energy metering module. Box door 2 is set with multiple observation ports 21, and observation port 21 is fixedly connected with observation window 22, and staff can directly observe electric energy meter 13 from observation window 22.

[0037] Referring to Figure 3 Support plate 12 is fixedly connected with multiple support blocks 121, and electric energy meter 13 is located between adjacent two support blocks 121. The surface of one of support blocks 121 is rotatably connected with baffle 122, and baffle 122 shields the interface of electric energy metering box, and the other support block 121 is used for abutting baffle 122. Baffle 122 is set with fixed rod 14 on baffle hole 123, and the end surface of fixed rod 14 is fixedly connected with fixed head 141, and the end surface of fixed rod 14 away from fixed head 141 is conical. The surface of support block 121 is set with fixed slot 124 for the insertion of fixed rod 14. Fixed rod 14 is set with accommodating groove 142 on the end surface close to fixed head 141, and accommodating groove 142 is regular pentagon, so that external personnel mistakenly think that it is the head of bolt, leading external personnel to rotate fixed rod 14 in the direction away from the bottom wall of fixed slot 124.

[0038] Referring to Figure 3 When fixed rod 14 is inserted into fixed slot 124 through baffle hole 123, fixed head 141 is located on the side of baffle 122 away from support block 121, and fixed head 141 limits the rotation of baffle 122 on support block 121 at this time, and baffle 122 shields the interface.

[0039] Referring to Figure 3 Fixed rod 14 is integrally formed with multiple fixed blocks 143 on the outer surface, multiple fixed blocks 143 are circumferentially arranged along fixed rod 14, and multiple fixed blocks 143 are arrayed along the length direction of fixed rod 14, and wherein fixed block 143 can be inserted into fixed slot 124 through baffle hole 123.

[0040] Referring to Figure 3The slot wall of the fixing groove 124 is provided with a sliding groove 128 extending along the length direction of the fixing groove 124. The bottom wall of the fixing groove 124 is fixedly connected with an elastic piece 15, which is a spring. The end face of the elastic piece 15 away from the bottom wall of the fixing groove 124 is fixedly connected with a pushing block 151 extending along the direction from the stop groove 126 to the fixing groove 124, and the pushing block 151 slides in the fixing groove 124 and the sliding groove 128. The surface of the pushing block 151 is fixedly connected with a dye bag 152, and the dye bag 152 has dyes therein and slides in the sliding groove 128. The elastic piece 15 drives the pushing block 151 to move away from the bottom wall of the fixing groove 124. When the pushing block 151 protrudes out of the fixing groove 124, the elastic piece 15 is in a non-stressed state; when the pushing block 151 is located in the fixing groove 124, the elastic piece 15 is in a compressed state.

[0041] With reference to Figure 3 and Figure 4 The surface of the supporting block 121 is provided with a through hole 16 communicating with the sliding groove 128, and the through hole 16 is detachably connected with a permeating block 161, which completely fills the through hole 16. The surface of the permeating block 161 close to the pushing block 151 is fixedly connected with a plurality of piercing strips 162 arrayed along the length direction of the permeating block 161. When the piercing strips 162 pierce the dye bag 152, the elastic piece 15 drives the pushing block 151 to move towards the permeating block 161, at this time, the dyes in the dye bag 152 permeate into the permeating block 161, and the staff can directly check whether the permeating block 161 is permeated to know whether there is electricity stealing by external personnel.

[0042] With reference to Figure 3 The surface of the permeating block 161 is provided with a plurality of perforations 163 arrayed along the direction of the placing plate. The perforations 163 include a first part 164 and a second part 165, and the first part 164 is located on the side of the second part 165 away from the piercing strips 162. The distance between the first part 164 and the ground gradually decreases along the direction from the sliding groove 128 to the through hole 16, and the distance between the second part 165 and the ground gradually increases along the direction from the sliding groove 128 to the through hole 16.

[0043] With reference to Figure 3 and Figure 4 When the dyes move into the perforations 163, the dyes are located on the side of the first part 164 and the second part 165 close to the ground, so that the dyes are not easy to directly leak out of the perforations 163, so as to facilitate the dyes to fully permeate in the permeating block 161. When the fixing rod 14 is inserted into the fixing groove 124, the fixing rod 14 abuts against the pushing block 151, at this time, the dye bag 152 in the pushing block 151 does not abut against the piercing strips 162 in the permeating block 161, that is, the dyes in the dye bag 152 are not in the permeating block 161.

[0044] With reference to Figure 3 , Figure 4 and Figure 5 , the surface of the support block 121 is provided with an operation hole 125 communicating with a fixing groove 124, and an operating rod 17 is rotatably connected in the operation hole 125. A stop groove 126 is formed in the groove wall of the fixing groove 124, the operating rod 17 is located in the stop groove 126, and a stop disc 171 is fixedly connected to the operating rod 17. The outer surface of the stop disc 171 is fixedly connected with a first stop strip 172 and a plurality of second stop strips 173.

[0045] With reference to Figure 3 and Figure 4 , the first stop strip 172 and the second stop strip 173 are arrayed along the circumference of the stop disc 171, and the distance between the end face of the first stop strip 172 and the axis of the stop disc 171 is greater than the distance between the end face of the second stop strip 173 and the axis of the stop disc 171. The first stop strip 172 and the second stop strip 173 can be inserted between two adjacent fixing blocks 143. A limiting block 127 is fixedly connected to the groove wall of the stop groove 126, and the limiting block 127 is located in the rotation path of the first stop strip 172, and the limiting block 127 is not located in the rotation path of the second stop strip 173.

[0046] With reference to Figure 3 and Figure 4 , the first stop strip 172 and the second stop strip 173 are both made of elastic material, the first stop strip 172 can be deformed towards the second stop strip 173, and the second stop strip 173 is deformed away from the first stop strip 172. When the operating rod 17 rotates, the operating rod 17 drives the stop disc 171 to rotate, allowing the first stop strip 172 to deform towards the second stop strip 173, so that the first stop strip 172 and the second stop strip 173 are both separated from the adjacent two fixing blocks 143, realizing that the first stop strip 172 does not limit the fixing blocks 143.

[0047] With reference to Figure 3 and Figure 4 , when the external personnel pulls the fixing rod 14 away from the bottom wall of the fixing groove 124, the first stop strip 172 and the second stop strip 173 are located between the adjacent two fixing blocks 143, until the second stop strip 173 is separated from the gap between the adjacent two fixing blocks 143, and the first stop strip 172 abuts against the limiting block 127, so that the two ends of the first stop strip 172 abut against the limiting block 127 and the fixing block 143 respectively, to limit the continuous movement of the fixing rod 14.

[0048] With reference to Figure 4The operating rod 17 is fixedly connected with a driving disc 174. The groove wall of the stop groove 126 is rotatably connected with a rotating disc 175. The rotating disc 175 and the driving disc 174 are in meshing connection. The groove wall of the stop groove 126 is slidably connected with a sliding strip 176. The sliding strip 176 can slide towards the fixed groove 124. The driving disc 174 is fixedly connected with a torsion spring 177. The torsion spring 177 drives the driving disc 174 to rotate, so that the driving disc 174 drives the stop disc 171 to rotate, that is, the first stop strip 172 can be located in the fixed groove 124.

[0049] With reference to Figure 4 When the operating rod 17 is rotated by the staff, the operating rod 17 drives the driving disc 174 to rotate. The driving disc 174 drives the sliding strip 176 to slide towards the fixed groove 124 through the rotating disc 175, so that the sliding strip 176 abuts against the pushing block 151, and the dye package 152 is limited to move towards the permeating block 161. Thus, the staff can pull out the fixed rod 14 from the fixed groove 124. When the fixed rod 14 is forcibly pulled by the external staff, the fixed block 143 drives the stop disc 171 to reverse through the first stop strip 172 and the second stop strip 173. The stop disc 171 drives the sliding strip 176 to slide away from the fixed groove 124 through the rotating disc 175, so that the sliding strip 176 is not limited to the pushing block 151. Thus, the elastic member 15 drives the pushing block 151 to move, that is, the dye in the dye package 152 permeates into the permeating block 161.

[0050] With reference to Figure 3 And Figure 5 The outer surface of the supporting block 121 is provided with a limiting hole 18 in communication with the stop groove 126. The limiting hole 18 is used for the first stop strip 172 to extend out. The surface of the supporting block 121 is fixedly connected with a limiting elastic piece 181. The limiting elastic piece 181 is bent in the direction of the limiting hole 18. The surface of the limiting elastic piece 181 is fixedly connected with a limiting block 182. The surface of the first stop strip 172 is provided with a stop hole 183 for the limiting block 182 to insert.

[0051] With reference to Figure 3 And Figure 5 When the first stop strip 172 extends out of the limiting hole 18, the first stop strip 172 drives the limiting elastic piece 181 to bend away from the supporting block 121 until the limiting block 182 is inserted into the stop hole 183, so that the limiting elastic piece 181 is fixed to the first stop strip 172.

[0052] The implementation principle of the modularized electricity larceny prevention energy metering box is as follows: first, the staff rotates the operating rod 17, so that the operating rod 17 drives the stop disc 171 to rotate, the first stop strip 172 is separated from the adjacent two fixed blocks 143, until the first stop strip 172 is inserted into the limiting hole 18, the limiting block 182 is inserted into the stop hole 183, and the fixation of the first stop strip 172 is realized; at this time, the driving disc 174 drives the rotating disc 175 to rotate, the rotating disc 175 drives the sliding strip 176 to abut against the pushing block 151, at this time, the elastic member 15 is difficult to move the pushing block 151, that is, the dye bag 152 cannot be pierced by the piercing strip 162 in the penetrating block 161.
