Description

Technical Field

[0001] The present application relates to the technical field of electric energy metering boxes, and in particular to a modular anti-theft electric energy metering box. Background Art

[0002] An energy meter box is a specialized device that integrates energy meter installation, electrical connection protection, and energy metering functions. It is typically used in residential or industrial areas. As a device for measuring electricity, the energy meter box directly affects electricity bill calculations.

[0003] In the related art, an electric energy meter box includes a box body and a box door, the box door is rotatably connected to the box body, a plurality of electric energy meters are arranged in the box body, and a plurality of interfaces are provided on the electric energy meters for connecting power lines.

[0004] Since the electricity meter box is related to the calculation of electricity bills, some outsiders may steal electricity. After opening the box door, the outsiders remove the wires from the interface and separate a part of the wires to steal electricity. Summary of the Invention

[0005] In order to improve the problem that electric energy meter boxes are easily stolen, the present application provides a modular anti-theft electric energy meter box.

[0006] This application provides a modular anti-theft electricity meter box, which adopts the following technical solutions: A modular anti-theft electricity meter box includes a box body and a box door, the box door is rotatably connected to the box body, an electricity meter is provided in the box body, the electricity meter is provided with multiple interfaces, a baffle for blocking the interfaces is provided in the box body, a fixing rod is provided on the baffle, a fixing groove for inserting the fixing rod is opened on the box body, a multiple fixing blocks are provided on the fixing rod, a stop disk is rotatably connected in the fixing groove, a first stop bar is provided on the stop disk, the moving path of the first stop bar and the insertion path of the fixed block intersect; when the fixed block is located on the side of the first stop bar facing the bottom wall of the fixing groove, the first stop bar restricts the fixed block from leaving the fixed groove, and at this time the baffle blocks the interface.

[0007] By adopting the above technical solution, the staff first rotates the stop disk to allow the stop disk to drive the first stop bar to move, so that the first stop bar can drive the fixed block to move toward the bottom wall of the fixed groove until the first stop bar does not abut the fixed block. Then the staff can pull the fixed block out of the fixed groove, so that the fixing rod can be removed from the box body, so that the baffle does not block the interface, allowing the staff to repair the internal circuit of the electricity meter; because the fixing rod is fixed in the fixed groove, the fixing rod limits the movement of the baffle, so that the baffle can stably block the interface, reducing the possibility of outsiders removing the wires from the interface, thereby reducing the possibility of outsiders stealing electricity and increasing the safety performance of the electricity meter box.

[0008] Optionally, a limit block is provided on the groove wall of the fixing groove, and the limit block is located on the rotation path of the first stop bar; when the first stop bar abuts against the limit block, the first stop bar restricts the fixing block from leaving the fixing groove.

[0009] By adopting the above technical solution, when the first stop bar abuts the limit block, the limit block is located on the rotation path of the first stop bar, and the limit block limits the continued movement of the first stop bar, so that the first stop bar can limit the fixed block from disengaging from the fixed groove, thereby reducing the possibility of outsiders forcibly pulling the fixed rod out of the fixed groove and increasing the reliability of the baffle's shielding of the interface.

[0010] Optionally, an elastic member is provided in the fixed groove, a pushing block is provided on the elastic member, a dye bag is provided on the pushing block, the elastic member drives the pushing block to move toward the fixed rod, a through hole connected to the fixed groove is provided on the box body, a penetration block for puncturing the dye bag is provided in the through hole; when the first stop bar abuts the limit block, the penetration block punctures the dye bag, and the dye in the dye bag is located in the penetration block.

[0011] By adopting the above technical solution, when the fixing rod is disengaged from the fixing groove, the elastic member drives the pushing block to move, allowing the penetration block to pierce the dye bag, so that the dye in the dye bag can penetrate into the penetration block, thereby making the penetration block have dye, so that the staff can observe the operation of someone trying to steal electricity in time, increase the possibility of being discovered by the staff after the electricity theft, and thus reduce the losses caused by the electricity theft.

[0012] Optionally, a through-hole connected to the fixed groove is provided on the penetration block, and the through-hole includes a first part and a second part, the first part is located on a side of the second part close to the fixed groove, the distance of the first part toward the ground gradually decreases along the direction from the dye bag to the through-hole, and the distance of the second part toward the ground gradually increases along the direction from the dye bag to the through-hole; when the dye bag is punctured, the dye in the dye bag is located in the first part and the second part.

[0013] By adopting the above technical solution, since the distance of the first part toward the ground gradually decreases along the direction from the dye bag to the perforation, and the distance of the second part toward the ground gradually increases along the direction from the dye bag to the perforation, the dye can be located between the first part and the second part, so that part of the dye is in the permeable block, avoiding the situation where the dye flows out directly from the perforation and causes insufficient penetration of the dye in the permeable block, and further allowing the dye in the permeable block to fully penetrate.

[0014] Optionally, a rotating disk is rotatably connected in the fixed groove, and the rotating disk is meshed with the stop disk. A sliding bar is slidably connected in the fixed groove, and the sliding bar is meshed with the rotating disk, and the moving path of the sliding bar intersects with the moving path of the pushing block; when the two sides of the first stop bar respectively abut the groove wall of the fixed groove and the fixed block, the sliding bar disengages from the moving path of the pushing block, and the penetration block punctures the dye bag; when the first stop bar does not abut the fixed block, the sliding bar is located on the moving path of the pushing block, and the penetration block does not puncture the dye bag.

[0015] By adopting the above technical solution, the staff rotates the stop disk so that the first stop bar does not abut the fixed block. Since the stop disk is engaged and connected to the rotating disk, the stop disk can drive the rotating disk to rotate, so that the rotating disk can smoothly drive the sliding bar to move. In addition, the moving path of the sliding bar and the moving path of the pushing block intersect, so that the sliding bar can abut the pushing block to limit the penetration block from piercing the dye bag; if an outsider wants to forcibly pull out the fixed rod, the two ends of the first stop bar respectively abut the groove wall of the fixed groove and the fixed block, so that the sliding bar is out of the moving path of the pushing block, so that the penetration block can pierce the dye bag, so that the dye in the dye bag is located on the penetration block, so that the staff can find it in time during daily maintenance.

[0016] Optionally, a limiting hole connected to the fixing slot is opened on the box body, and the limiting hole is for the first stop bar to extend out. A limiting spring is provided on the box body, and the limiting spring is deformed toward the limiting hole; when the first stop bar extends out of the limiting hole, the limiting spring abuts against the first stop bar.

[0017] By adopting the above technical solution, when the first stop bar extends out of the limiting hole, the limiting spring sheet is deformed toward the limiting hole, causing the limiting spring sheet to abut against the first stop bar, so that the first stop bar is subjected to the force of the limiting spring sheet, making it difficult for the first stop bar to detach from the limiting hole, thereby allowing the first stop bar to be stably located at the limiting hole, reducing the possibility of the first stop bar moving in the limiting hole; the staff can judge whether the first stop bar has moved to the specified position by whether the limiting spring sheet is bent, that is, whether the sliding bar abuts against the push block, so that the dye bag will not be punctured when the staff moves the fixed rod.

[0018] Optionally, a limiting block is provided on the limiting spring piece, and a stopping hole for inserting the limiting block is opened on the first stopping bar; when the first stopping bar extends out of the limiting hole, the limiting block is inserted into the stopping hole.

[0019] By adopting the above technical solution, the limiting block is inserted into the stop hole, so that the limiting block limits the first stop bar, further restricts the first stop bar, reduces the movement of the limiting block in the limiting hole, and prevents the stop disk from moving when the staff rotates the fixed rod.

[0020] Optionally, a torsion spring is provided on the rotating disk, and the torsion spring is used to drive the sliding bar to separate from the moving path of the pushing block through the rotating disk; when the first stop bar extends out of the limiting hole, the sliding bar is located on the moving path of the pushing block.

[0021] By adopting the above technical solution, the rotating disk is driven to rotate by the torsion spring, so that the first stop bar in the rotating disk can abut the fixed block. The first stop bar limits the movement of the fixed block, reducing the situation where the first stop bar is separated from the fixed block, thereby increasing the limiting effect of the first stop bar on the fixed block.

[0022] Optionally, a surface of the fixing rod extending out of the box body is provided with a receiving groove for inserting a tool, and the fixing block extends along the circumference of the fixing rod; when the fixing rod moves in a direction away from the bottom wall of the fixing groove, the penetration block punctures the dye bag.

[0023] By adopting the above technical solution, since the receiving groove is for inserting tools, an outsider can use the tool to twist the fixing rod and pull the fixing rod to move in a single direction away from the bottom wall of the fixing groove, so that the penetration block can pierce the dye bag, so that the staff can check the presence of dye in the penetration block in time; by setting the receiving groove to mislead the operation of the outsider, the situation of the outsider not twisting the fixing rod is reduced.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The staff first rotates the stop disk to allow the stop disk to drive the first stop bar to move, so that the first stop bar can drive the fixed block to move toward the bottom wall of the fixed groove until the first stop bar does not abut the fixed block. Then the staff can pull the fixed block out of the fixed groove, so that the fixing rod can be removed from the box body, so that the baffle does not block the interface, allowing the staff to repair the internal circuit of the electricity meter; because the fixing rod is fixed in the fixed groove, the fixing rod limits the movement of the baffle, so that the baffle can stably block the interface, reducing the possibility of outsiders removing the wires from the interface, thereby reducing the possibility of outsiders stealing electricity and increasing the safety performance of the electricity meter box.

[0025] 2. Since the receiving groove is for inserting tools, outsiders can use the tools to twist the fixing rod and pull the fixing rod to move in a single direction away from the bottom wall of the fixing groove, so that the penetration block can pierce the dye bag, so that the staff can check the presence of dye in the penetration block in time; by setting the receiving groove, the operation of outsiders can be misled, reducing the situation where outsiders do not twist the fixing rod.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-5 This application is described in further detail.

[0029] This embodiment discloses a modular anti-theft electric energy meter box. Figure 1 and Figure 2A modular anti-theft electricity meter box includes a housing 1 and a door 2. The housing 1 is provided with multiple accommodating slots 11 for accommodating electrical components. The housing can be injection molded from any of PC+ABS, PC+ASA gold-containing plastic, or PP+LGF (long glass fiber reinforced polypropylene); or compression molded from high-performance SMC composite materials or machined and welded from stainless steel.

[0030] Reference Figure 1 and Figure 2 A support plate 12 is fixedly connected to the receiving groove 11. Multiple energy meters 13 are bolted to the support plate 12. The multiple energy meters 13 and the support plate 12 form an energy metering module. The door 2 is provided with multiple observation ports 21, each of which is fixedly connected to an observation window 22. The staff can directly observe the energy meters 13 through the observation window 22.

[0031] Reference Figure 3 A plurality of support blocks 121 are fixedly connected to the support plate 12, and the electric energy meter 13 is located between two adjacent support blocks 121. A baffle 122 is rotatably connected to the surface of one of the support blocks 121. The baffle 122 blocks the interface of the electric energy meter box, and the other support block 121 is used to abut the baffle 122. A baffle hole 123 is provided on the baffle 123, and a fixing rod 14 is provided on the baffle hole 123. A fixing head 141 is fixedly connected to the end face of the fixing rod 14. The end face of the fixing rod 14 away from the fixing head 141 is conical. A fixing groove 124 is provided on the surface of the support block 121 for inserting the fixing rod 14. A receiving groove 142 is provided on the end face of the fixing rod 14 near the fixing head 141. The receiving groove 142 is a regular pentagon, which can be mistaken for the head of a bolt by outsiders, causing them to twist the fixing rod 14 in a direction away from the bottom wall of the fixing groove 124.

[0032] Reference Figure 3 When the fixing rod 14 passes through the blocking hole 123 and is inserted into the fixing groove 124, the fixing head 141 is located on the side of the baffle 122 away from the support block 121. At this time, the fixing head 141 limits the baffle 122 from rotating on the support block 121, and the baffle 122 blocks the interface.

[0033] Reference Figure 3 A plurality of fixing blocks 143 are integrally formed on the outer surface of the fixing rod 14 , and the plurality of fixing blocks 143 are arranged around the circumference of the fixing rod 14 , and the plurality of fixing blocks 143 are distributed in an array along the length direction of the fixing rod 14 , wherein the fixing blocks 143 can pass through the blocking hole 123 and be inserted into the fixing groove 124 .

[0034] Reference Figure 3The fixed slot 124 has a sliding slot 128 defined in its wall, extending along the length of the fixed slot 124. An elastic member 15, in the form of a spring, is fixedly attached to the bottom wall of the fixed slot 124. A push block 151 is fixedly attached to the end face of the elastic member 15 facing away from the bottom wall of the fixed slot 124. The push block 151 extends from the retaining slot 126 toward the fixed slot 124 and slides within the fixed slot 124 and the sliding slot 128. A dye bag 152 containing dye is fixedly attached to the surface of the push block 151, which slides within the sliding slot 128. The elastic member 15 drives the push block 151 away from the bottom wall of the fixed slot 124. When the push block 151 protrudes from the fixed slot 124, the elastic member 15 is in a non-stressed state. When the push block 151 is within the fixed slot 124, the elastic member 15 is in a compressed state.

[0035] Reference Figure 3 and Figure 4 The support block 121 has a through-hole 16 on its surface, which connects to the sliding slot 128. A penetration block 161 is detachably connected to the through-hole 16, completely filling the through-hole 16. A plurality of puncture bars 162 are fixedly connected to the surface of the penetration block 161 near the push block 151. The puncture bars 162 are arranged in an array along the length of the penetration block 161. When the puncture bars 162 puncture the dye pack 152, the elastic member 15 drives the push block 151 toward the penetration block 161. The dye in the dye pack 152 then penetrates the penetration block 161. This allows staff to directly check whether the penetration block 161 has been penetrated, thereby determining whether an outsider has attempted to steal electricity.

[0036] Reference Figure 3 The surface of the permeable block 161 is provided with a plurality of perforations 163, arranged in an array along the direction of the placement plate. Perforations 163 include a first portion 164 and a second portion 165, with the first portion 164 located on the side of the second portion 165 away from the piercing strip 162. The distance between the first portion 164 and the ground gradually decreases along the direction from the sliding slot 128 to the through hole 16, while the distance between the second portion 165 and the ground gradually increases along the direction from the sliding slot 128 to the through hole 16.

[0037] Reference Figure 3 and Figure 4 When the dye moves into the perforation 163, the dye is located on the side of the first portion 164 and the second portion 165 closer to the ground, preventing the dye from leaking directly from the perforation 163 and allowing the dye to fully penetrate the permeation block 161. When the fixing rod 14 is inserted into the fixing groove 124, the fixing rod 14 abuts the push block 151. At this time, the dye bag 152 in the push block 151 does not abut the puncture strip 162 in the permeation block 161, that is, the dye in the dye bag 152 is not in the permeation block 161.

[0038] Reference Figure 3 、 Figure 4 and Figure 5 The support block 121 has an operating hole 125 on its surface that communicates with the fixing slot 124. The operating rod 17 is rotatably connected to the operating hole 125. A retaining groove 126 is defined on the wall of the fixing slot 124. The operating rod 17 is positioned within the retaining groove 126. A retaining plate 171 is fixedly connected to the operating rod 17. A first retaining bar 172 and a plurality of second retaining bars 173 are fixedly connected to the outer surface of the retaining plate 171.

[0039] Reference Figure 3 and Figure 4 The first and second stop bars 172, 173 are arranged in a circumferential array along the stop disk 171, and the distance between the end surface of the first stop bar 172 and the axis of the stop disk 171 is greater than the distance between the end surface of the second stop bar 173 and the axis of the stop disk 171. The first and second stop bars 172, 173 can be inserted between two adjacent fixed blocks 143. A limit block 127 is fixedly connected to the wall of the stop groove 126. The limit block 127 is located in the rotation path of the first stop bar 172 and is not located in the rotation path of the second stop bar 173.

[0040] Reference Figure 3 and Figure 4 The first stop bar 172 and the second stop bar 173 are both made of elastic material. The first stop bar 172 can deform toward the second stop bar 173, and the second stop bar 173 can deform away from the first stop bar 172. When the operating lever 17 rotates, the operating lever 17 drives the stop plate 171 to rotate, causing the first stop bar 172 to deform toward the second stop bar 173, so that the first stop bar 172 and the second stop bar 173 are separated from between two adjacent fixing blocks 143, so that the first stop bar 172 does not restrict the fixing blocks 143.

[0041] Reference Figure 3 and Figure 4 When an outsider pulls the fixing rod 14 in a direction away from the bottom wall of the fixing groove 124, the first stop bar 172 and the second stop bar 173 are both located between two adjacent fixing blocks 143 until the second stop bar 173 is separated from the gap between the two adjacent fixing blocks 143 and the first stop bar 172 abuts the limit block 127, so that the two ends of the first stop bar 172 respectively abut the limit block 127 and the fixing block 143 to prevent the fixing rod 14 from continuing to move.

[0042] Reference Figure 4A driving disk 174 is fixedly connected to the operating rod 17. A rotating disk 175 is rotatably connected to the wall of the retaining groove 126. The rotating disk 175 and the driving disk 174 engage with each other. A sliding bar 176 is slidably connected to the wall of the retaining groove 126. The sliding bar 176 can slide toward the fixed groove 124. A torsion spring 177 is fixedly connected to the driving disk 174. The torsion spring 177 drives the driving disk 174 to rotate, and the driving disk 174 drives the retaining disk 171 to rotate, that is, the first retaining bar 172 can be located within the fixed groove 124.

[0043] Reference Figure 4 When a staff member rotates the operating lever 17, the operating lever 17 drives the active disk 174 to rotate. The active disk 174 drives the sliding bar 176 to slide toward the fixed slot 124 via the rotating disk 175. The sliding bar 176 abuts the push block 151, restricting the movement of the dye bag 152 toward the penetration block 161, allowing the staff member to pull the fixed rod 14 out of the fixed slot 124. When an outsider forcibly pulls the fixed rod 14, the fixed block 143 drives the stop disk 171 to reverse via the first and second stop bars 172 and 173. The stop disk 171 drives the sliding bar 176 to slide away from the fixed slot 124 via the rotating disk 175. The sliding bar 176 no longer restricts the push block 151, allowing the elastic member 15 to drive the push block 151 to move. This allows the dye in the dye bag 152 to penetrate into the penetration block 161.

[0044] Reference Figure 3 and Figure 5 The outer surface of the support block 121 is provided with a limiting hole 18 that communicates with the retaining groove 126. The first retaining bar 172 extends from the limiting hole 18. A limiting spring 181 is fixedly connected to the surface of the support block 121. The limiting spring 181 bends toward the limiting hole 18. A limiting block 182 is fixedly connected to the surface of the limiting spring 181. The first retaining bar 172 is provided with a retaining hole 183 for the insertion of the limiting block 182.

[0045] Reference Figure 3 and Figure 5 When the first stop bar 172 extends out of the limiting hole 18, the first stop bar 172 drives the limiting spring 181 to bend in a direction away from the support block 121 until the limiting block 182 is inserted into the stop hole 183, thereby fixing the limiting spring 181 to the first stop bar 172.

[0046] The implementation principle of a modular anti-theft electricity meter box in an embodiment of the present application is as follows: the staff first rotates the operating lever 17, allowing the operating lever 17 to drive the stop disk 171 to rotate, so that the first stop bar 172 is disengaged from between the two adjacent fixed blocks 143, until the first stop bar 172 is inserted into the limiting hole 18, and the limiting block 182 is inserted into the stop hole 183, so that the first stop bar 172 is fixed; at this time, the active disk 174 drives the rotating disk 175 to rotate, and the rotating disk 175 drives the sliding bar 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 punctured by the puncture bar 162 in the penetration block 161.
