Description

Technical Field

[0001] This invention relates to the field of anti-theft electricity devices, and in particular to an anti-theft electricity device for an electricity metering box. Background Technology

[0002] An anti-theft device is a device that prevents a third party from illegally or improperly stealing or misappropriating electricity.

[0003] Existing methods for preventing electricity theft typically involve sealing the electricity meter box with a lead seal after the box door is closed. Staff can then check the seal information to see if the electricity meter box has been opened without authorization to steal electricity.

[0004] A search revealed a Chinese patent for an anti-theft device for electricity metering boxes (publication number CN206638716U). This patented technology provides power to the device during use, enabling it to alarm and cut off power when the box door is illegally opened. While this design can promptly trigger an alarm and cut off power after the box door is opened, the device stops working due to lack of power supply after a power outage. Furthermore, when using lead seals for protection, the steel wire of the seal can be cut and reused, affecting the normal judgment of the staff during inspection. Both of these existing methods have significant limitations and are not conducive to the long-term protection of electricity metering boxes.

[0005] Therefore, those skilled in the art have provided an anti-theft device for electricity metering boxes to solve the problems mentioned in the background art. Summary of the Invention

The other end of one rotating block is fixedly connected to a connecting rod. The other end of the connecting rod passes through the second connecting shell and is fixedly connected to a knob.

[0010] Preferably, the inner wall of the first connecting shell is fixedly connected with two connecting rings located between the two partitions, and the inner side of the connecting rings is fixedly connected with evenly distributed slots.

[0011] Preferably, the extension line of one side of the inner wall of the card slot passes through the center of the connecting ring, the inner wall of the other side of the card slot is set with an inclined surface, and the included angle of the inner corner of the card slot is an acute angle.

[0012] Preferably, the surface of the partition is fixedly connected with two symmetrically distributed buckles, and the other end of the buckles extends into the interior of the adjacent slot.

[0013] Preferably, the auxiliary mechanism includes a connecting plate slidably connected to the inner wall of the screw hole, a positioning hook fixedly connected to the top of the connecting plate, a pressure block fixedly connected to the top of the positioning hook, a sliding rod fixedly connected to the bottom of the connecting plate, a slider fixedly connected to the lower end of the sliding rod through the screw hole and slidably connected to the inner wall of the housing, a first spring fixedly connected between the top of the slider and the inner wall of the housing, and a sealing groove communicating with the screw hole is opened on the surface of the slot.

[0014] Preferably, the auxiliary mechanism further includes two support blocks fixedly connected to the top of the tongue and symmetrically distributed around the bolt. The top of the support blocks has a connecting hole that penetrates the tongue and communicates with the sealing groove.

[0015] Preferably, the wiring mechanism includes a mounting block fixedly connected to the mounting cavity, a uniformly distributed groove is provided on one side of the mounting block, a crossbar is fixedly connected to the inner wall of the groove, a uniformly distributed wiring groove is provided on the top of the mounting block, the wiring groove is connected to the adjacent groove, and a wire hole is provided on the surface of the housing that is connected to the wiring groove.

[0016] Preferably, the top of the mounting block has a mounting groove, the inner wall of the mounting groove is slidably connected to a trigger block, the bottom of the trigger block is fixedly connected to a reset rod, the lower end of the reset rod passes through the mounting groove and is fixedly connected to a buffer plate that is slidably connected to the inner wall of the mounting block, the top of the buffer plate is fixedly connected to the inner wall of the mounting block, a second spring is fixedly connected to the top of the buffer plate and the inner wall of the mounting block, a pressure sensor is provided inside the mounting block located below the buffer plate, a limiting block is provided at the bottom of the cover located inside the groove, and a trigger rod for squeezing the trigger block is fixedly connected to the bottom of the cover.

[0017] Preferably, a microcontroller is provided on the top of the mounting block, a wireless transmission module is provided on the surface of the microcontroller, and a battery is provided inside the mounting block.

[0018] The beneficial effects of this invention are:

[0019] 1. The interplay between the anti-theft mechanism, cover, bolts, and screw holes allows the bolts to be positioned after the cover is closed via a lead seal mechanism and auxiliary mechanisms. The cover cannot be opened normally without damaging the lead seal mechanism. The cooperation between the lead seal mechanism and auxiliary mechanisms conceals most of the wire sealing. To open the cover, the lead seal mechanism must be cut to release the bolt's position. The lead seal mechanism is ineffective if damaged. This design effectively improves anti-theft performance. Disassembling the lead seal mechanism damages the electronic tag, rendering it unusable. This allows for rapid detection of unauthorized opening of the cover for electricity theft based on backup electronic tag information, facilitating long-term equipment protection.

[0020] 2. The battery provides power to the microcontroller, wireless transmission module, and pressure sensor in the event of a power outage. Opening the cover separates the trigger rod from the trigger block, which in turn causes the buffer plate to separate from the pressure sensor under the action of the second spring. Once the pressure sensor detects that the pressure is below a preset value, it transmits a signal to the microcontroller. The microcontroller then transmits the signal to a remote terminal via the wireless transmission module, thus alerting power company personnel that someone has opened the electricity metering box. This improves the device's anti-theft performance and avoids situations where anti-theft mechanisms are ineffective during power outages.

[0021] 3. The design of grooves, wire holes, crossbars, and wiring channels enables an approximate Z-shaped wiring method for external connections. After the cover is closed, the limiting block can be inserted into the groove to block it. This, combined with the Z-shaped wiring design, increases the difficulty of connecting the wire to the terminal block without opening the cover, preventing criminals from connecting the wire to the terminal block through the wire hole to steal electricity during power outages.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] In practical implementation: such as Figure 1-11 As shown, an anti-theft device for an electricity metering box includes: a housing 1, with a mounting cavity 102 on the top of the housing 1, a cover 101 hinged to the top of the housing 1, the cover 101 covering the mounting cavity 102, a slot on the surface of the housing 1, a tongue 103 fixedly connected to one side of the cover 101 inside the slot, a screw hole 105 on the inner wall of the slot, a bolt 104 on the top of the cover 101, the lower end of the bolt 104 penetrating through the cover 101 and threadedly connected to the screw hole 105; an anti-theft mechanism 2; wherein the anti-theft mechanism 2 includes a lead seal mechanism 21 disposed on the surface of the tongue 103, the lead seal mechanism 21 facilitating inspection by staff; the anti-theft mechanism 2 also includes an auxiliary mechanism 22 disposed inside the screw hole 105, the auxiliary mechanism 22 assisting in the use of the lead seal mechanism 21; and a wiring mechanism 3 disposed inside the mounting cavity 102, the wiring mechanism 3 improving the anti-theft effect of the device.

[0036] The lead seal mechanism 21 includes a first connecting shell 2101 and a steel wire sealing line 2103 disposed above the tongue 103. An integrally formed second connecting shell 2102 is fixedly connected to the middle of the surface of the first connecting shell 2101. An electronic tag 2106 is disposed inside the second connecting shell 2102. Two symmetrically distributed through holes 2104 are opened on the surface of the first connecting shell 2101.

[0037] The two ends of the steel wire sealing line 2103 can pass through two through holes 2104 respectively. The electronic tag 2106 facilitates the staff to check the information. The mounting cavity 102 is equipped with wiring terminals for external wiring connections.

[0038] like Figure 3 , Figure 4 and Figure 5As shown, two symmetrically distributed rotating blocks 2112 are slidably connected to the inner wall of the first connecting shell 2101. Mounting rods 2108 are fixedly connected to opposite sides of each rotating block 2112. A partition plate 2111 is fixedly connected to the other end of each mounting rod 2108. A cutting portion 2110 is fixedly connected between the two partition plates 2111. A through hole 2109, coaxially aligned with the adjacent through hole 2104, is opened on the surface of the mounting rod 2108. A connecting rod 2107 is fixedly connected to the other end of one rotating block 2112. The other end of the connecting rod 2107 passes through the second connecting shell 2102 and is fixed... A knob 2105 is fixedly connected. The inner wall of the first connecting shell 2101 is fixedly connected with two connecting rings 2113 located between two partitions 2111. The inner side of the connecting rings 2113 is fixedly connected with evenly distributed slots 2114. The extension line of one side of the inner wall of the slots 2114 passes through the center of the connecting rings 2113. The inner wall of the other side of the slots 2114 is set with an inclined surface. The included angle of the inner corners of the slots 2114 is an acute angle. The surface of the partitions 2111 is fixedly connected with two symmetrically distributed buckles 2115. The other end of the buckles 2115 extends into the interior of the adjacent slots 2114.

[0039] The two ends of the wire sealing line 2103 are passed through two through holes 2104 and corresponding through holes 2109 respectively. After the two ends of the wire sealing line 2103 pass through the first connecting shell 2101, the connecting rod 2107 can be rotated by rotating the knob 2105. In this process, the rotating block 2112, the mounting rod 2108, the partition plate 2111 and the cutting part 2110 can be rotated synchronously, thereby tightening the wire sealing line 2103 into the interior of the first connecting shell 2101. At the same time, the buckle 2115 can be rotated synchronously. The buckle 2115 rotates in the forward direction. During the rotation, the buckle 2115 can be squeezed along the inclined inner wall of the slot 2114 to retract it without affecting the rotation of the buckle 2115. Until the buckle 2115 moves to the next slot 2114, it can be reset and inserted into the slot 2114 under its own elastic force. It also cooperates with the other side wall to block the end of the buckle 2115 to prevent it from reversing, thereby achieving the effect of unidirectional locking of the wire sealing line 2103. The first connecting shell 2101, the second connecting shell 2102, the buckle 2115, and the connecting ring 2113 are all plastic material components.

[0040] When the wire sealing line 2103 is tightened inside the first connecting shell 2101, and it is necessary to contact the wire sealing line 2103, the electronic tag 2106 and the cutting part 2110 are broken and separated from the middle by cutting the middle part of the first connecting shell 2101 and the second connecting shell 2102. At this time, the electronic tag 2106 is damaged and cannot be used again, thus preventing criminals from using it again. Since the first connecting shell 2101 is separated from the middle, the buckle 2115 can be separated from the slot 2114 by pulling the cutting part 2110, thereby reversing the installation rod 2108 and releasing the restriction on the wire sealing line 2103, thus allowing the wire sealing line 2103 to be disassembled.

[0041] like Figure 2 , Figure 6 , Figure 9 and Figure 10 As shown, the auxiliary mechanism 22 includes a connecting plate 2204 slidably connected to the inner wall of the screw hole 105. A positioning hook 2208 is fixedly connected to the top of the connecting plate 2204. A pressure block 2209 is fixedly connected to the top of the positioning hook 2208. A sliding rod 2206 is fixedly connected to the bottom of the connecting plate 2204. The lower end of the sliding rod 2206 passes through the screw hole 105 and is fixedly connected to a slider 2205 that is slidably connected to the inner wall of the housing 1. A first spring 2207 is fixedly connected between the top of the slider 2205 and the inner wall of the housing 1. A sealing groove 2203 communicating with the screw hole 105 is opened on the surface of the slot. The auxiliary mechanism 22 also includes two support blocks 2201 fixedly connected to the top of the tongue 103 and symmetrically distributed with the bolt 104 as the center. A connecting hole 2202 passing through the tongue 103 and communicating with the sealing groove 2203 is opened on the top of the support block 2201.

[0042] When installing the lead seal mechanism 21, first place the steel wire sealing line 2103 in a U-shape inside the sealing groove 2203. At this time, the steel wire sealing line 2103 can pass through the screw hole 105. Then, wrap the steel wire sealing line 2103 around the positioning hook 2208 so that it is located inside the positioning hook 2208. Next, close the cover 101 to cover the mounting cavity 102 and protect the wiring terminals. During this process, pass both ends of the steel wire sealing line 2103 through the two connecting holes 2202 respectively, and tighten them with the screw holes 105 using bolts 104. During the tightening of the bolts 104, the pressure block 2209 can be gradually squeezed. The pressure block 2209 can push the positioning hook 2208, slide bar 2206 and slider 2205 down and stretch the first spring 2207. At this time, it can pull the wire sealing line 2103 down synchronously, so that the wire sealing line 2103 is limited between the bottom of the bolt 104 and the screw hole 105, achieving the effect of initially limiting the position of the wire sealing line 2103. Moreover, since the tongue 103 blocks the sealing groove 2203, most of the wire sealing line 2103 can be hidden, preventing criminals from cutting the wire sealing line 2103 and reusing the lead seal mechanism 21, thus improving the anti-theft effect.

[0043] After the bolt 104 is tightened, pass both ends of the wire sealing line 2103 through the first connecting shell 2101 and turn the knob 2105 to tighten the wire sealing line 2103. At this time, the first connecting shell 2101 is located on the two support blocks 2201. Due to the restriction of the first connecting shell 2101, the lead sealing mechanism 21 must be disassembled before the bolt 104 can be disassembled, thereby improving the anti-theft effect. The ends of the wire sealing line 2103 that are tightened and pass through the first connecting shell 2101 can be trimmed according to the actual situation to complete the installation.

[0044] When the cover 101 needs to be opened after installation, it can only be opened by cutting the lead seal mechanism 21 to release the limit on the bolt 104. Since cutting the lead seal mechanism 21 will damage the electronic tag 2106, the electronic tag 2106 will no longer be usable. This avoids the situation where criminals damage the lead seal mechanism 21 and reuse the electronic tag 2106. It has the effect of damage causing incompetence and improves the anti-theft performance.

[0045] like Figure 2 , Figure 7 and Figure 11 As shown, the wiring mechanism 3 includes a mounting block 301 fixedly connected to the mounting cavity 102. A uniformly distributed groove 303 is provided on one side of the mounting block 301. A crossbar 304 is fixedly connected to the inner wall of the groove 303. A uniformly distributed wiring groove 305 is provided on the top of the mounting block 301. The wiring groove 305 is connected to the adjacent groove 303. A wire hole 306 connected to the wiring groove 305 is provided on the surface of the housing 1.

[0046] The arrangement of groove 303, crossbar 304, wiring groove 305 and wire hole 306 enables the external wiring to be distributed in an approximately Z-shape when it passes through wire hole 306 and connects to terminal block. This is achieved through the mutual cooperation of groove 303, wiring groove 305 and crossbar 304.

[0047] like Figure 6 , Figure 7 , Figure 8 and Figure 11As shown, the top of the mounting block 301 has a mounting groove, the inner wall of the mounting groove is slidably connected to a trigger block 307, the bottom of the trigger block 307 is fixedly connected to a reset rod 310, the lower end of the reset rod 310 passes through the mounting groove and is fixedly connected to a buffer plate 311 that is slidably connected to the inner wall of the mounting block 301, the top of the buffer plate 311 is fixedly connected to the inner wall of the mounting block 301, the mounting block 301 is equipped with a pressure sensor 308 located below the buffer plate 311, the bottom of the cover 101 is equipped with a limiting block 302 located inside the groove 303, the bottom of the cover 101 is fixedly connected to a trigger rod 312 for squeezing the trigger block 307, the top of the mounting block 301 is equipped with a microcontroller 315, the surface of the microcontroller 315 is equipped with a wireless transmission module 313, and the mounting block 301 is equipped with a battery 314.

[0048] After the cover 101 is closed, the limiting block 302 can be inserted into the inside of the groove 303, thereby blocking the groove 303. Combined with the Z-shaped wiring, it can prevent criminals from connecting the wire through the wire hole 306 to the terminal block to steal electricity during power outages.

[0049] The battery 314 supplies power to the microcontroller 315, the wireless transmission module 313, and the pressure sensor 308 during power outages. During power-on periods, it charges the battery 314. When the cover 101 is closed, the trigger rod 312 presses down the trigger block 307, causing it to drive the reset rod 310, which in turn causes the buffer plate 311 to apply pressure to the pressure sensor 308. At the same time, the second spring 309 is stretched. When the cover 101 is opened, the second spring 309 causes the reset rod 310, the buffer plate 311, and the trigger block 307 to reset. As a result, the pressure sensor 308 detects that the pressure is lower than the preset value and transmits a signal to the microcontroller 315. The microcontroller 315 then transmits the signal to a remote terminal via the wireless transmission module 313. The specific remote terminal can be a power company's control terminal, a mobile phone, or other devices capable of receiving signals, thereby alerting power company staff that someone has opened the power metering box.

[0050] In use, the external wiring is connected to the terminal block through the wire hole 306. The external wiring is arranged in an approximately Z-shaped pattern due to the interaction of the groove 303, the wiring groove 305, and the crossbar 304. The steel wire sealing line 2103 is then placed in a U-shape inside the sealing groove 2203, positioned inside the positioning hook 2208. The cover 101 is then closed. At this point, the tongue 103 can be inserted into the slot, and both ends of the steel wire sealing line 2103 pass through the two connecting holes 2202 respectively. Simultaneously, the limiting block 302 can be inserted into the groove 303, thus blocking the groove 303. This Z-shaped wiring arrangement helps to avoid… To prevent criminals from connecting the line to the terminal block through the wire hole 306 to steal electricity during power outages, the bolt 104 is tightened with the screw hole 105 to fix the position of the cover 101. During this process, with the cooperation of the lead sealing mechanism 21 and the auxiliary mechanism 22, the two ends of the steel wire sealing wire 2103 can be passed through the first connecting shell 2101 and the knob 2105 can be turned to tighten the steel wire sealing wire 2103. At this time, the first connecting shell 2101 is located on the two support blocks 2201. Due to the restriction of the first connecting shell 2101, the lead sealing mechanism 21 must be disassembled before the bolt 104 can be disassembled.

[0051] When the cover 101 needs to be opened after installation, it can only be opened by cutting the lead seal mechanism 21 to release the limit on the bolt 104. Since cutting the lead seal mechanism 21 will damage the electronic tag 2106, the electronic tag 2106 will no longer be usable. This avoids the situation where criminals damage the lead seal mechanism 21 and reuse the electronic tag 2106. It has the effect of damage causing incompetence and improves the anti-theft performance.

[0052] It should be noted that the electronic tag 2106, pressure sensor 308, wireless transmission module 313, battery 314, and microcontroller 315 mentioned above are all devices with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, the electronic tag 2106, pressure sensor 308, wireless transmission module 313, battery 314, and microcontroller 315 can be powered by the built-in power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0053] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
