Description

Technical Field

[0001] The present invention relates to the technical field of electric meters, and specifically to an electric meter structure with a mechanical anti-theft function. Background Technique

[0002] An electric meter is an instrument used to measure electric energy, also known as a watt-hour meter, a fire meter, an electric energy meter, a kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities. It is classified into industrial and civil meters, electronic standard meters, maximum demand meters, multi-rate meters, etc. according to its use; it is classified into induction type, static type, electromechanical integrated type, etc. according to its structure and working principle; it is classified into AC meters and DC meters according to the nature of the power supply connected; it is classified into common ordinary meters and standard meters according to the accuracy level; it is classified into direct connection type and indirect connection type according to the installation wiring method; it is classified into single-phase, three-phase three-wire, and three-phase four-wire electric energy meters according to the electrical equipment. As an important tool for measuring electric energy, it plays a key role in the power system and daily life.

[0003] After a large amount of retrieval, it is found that the prior art publication number is CN114264855B, which discloses an electric meter with moisture-proof and anti-theft functions, including a housing and an electric meter body. The electric meter body is fixedly installed inside the housing. A door panel is rotatably installed on the front surface of the housing through two rotating shafts. A cover shell is fixedly installed inside the housing. A rotating assembly and a guide shaft are rotatably installed inside the cover shell. A pull rope is wound on the rotating assembly. The movable end of the pull rope bypasses the guide shaft and is fixedly connected to one of the rotating shafts. A moving assembly and a telescopic assembly are fixedly installed inside the cover shell. The bottom of the telescopic assembly is clamped with a connecting assembly. Through the cooperation between the rotating assembly, the moving assembly, the telescopic assembly, and the connecting assembly, etc., the effective protection of the electric meter body can be realized, the installation reliability of the electric meter body is improved, and at the same time, the electricity query and maintenance replacement of the electric meter body are not affected.

[0004] The above-mentioned existing electric meter anti-theft methods all lock the electric meter inside the box body. However, when thieves find it difficult to open the box door, they will choose to violently remove the electric meter without damaging the electric meter. After the box door is violently removed, the thieves only need to cut the wires at both ends of the electric meter to easily disassemble the electric meter, and the anti-theft performance is not high. Therefore, based on the above retrieval and combined with the existing problems, an electric meter structure with a mechanical anti-theft function is provided. Summary of the Invention

[0005] The purpose of the present invention is to provide an electric meter structure with a mechanical anti-theft function to solve the problem of low anti-theft performance proposed in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] An electricity meter structure with mechanical anti-theft function, including an electricity meter box. An electricity meter box is placed inside the electricity meter box. One end of the electricity meter box is provided with a connection line and an electricity meter for displaying the electricity consumption. Inside the electricity meter box near the electricity meter, a limit mechanism for mechanical anti-theft is provided. A trigger ringing mechanism for emitting an alarm sound when the electricity meter is illegally stolen is arranged between the limit mechanism and the electricity meter. Specifically, the electricity meter box is restricted and fixed in the electricity meter box through a mechanical structure, so that thieves cannot take it out, playing a role in anti-theft. At the same time, the limit mechanism makes the installation of the electricity meter box more convenient. After the electricity meter box is violently damaged through a fragile structure, the electricity meter box emits an alarm, thereby strengthening the anti-theft function.

[0008] Further, the limit mechanism includes an installation ring, and the installation ring is arranged at the corner of the electricity meter box. A rotating rod is rotatably arranged on the inner wall of the installation ring. A limit rod is fixedly installed at the side end of the rotating rod away from the electricity meter box. A limit plate is rotatably installed at one end of the limit rod away from the rotating rod. When installing the electricity meter box, rotate the limit rod so that the limit plate arranged at one end of the limit rod presses against and fits on the inner wall of the electricity meter box, so that there is no need to use other bolts to fix the electricity meter box, making the installation of the electricity meter box more convenient.

[0009] Further, a push rod is rotatably installed at the end of the rotating rod away from the limit rod. A linkage telescopic rod is rotatably installed at the end of the push rod away from the rotating rod. A toothed rod is rotatably installed at the end of the linkage telescopic rod away from the push rod, and the toothed rod is slidably installed on the inner wall of the electricity meter box. A driving gear is rotatably installed on the inner wall of the electricity meter box near the toothed rod. The driving gear is meshed and connected with a driven gear, and the toothed rod is meshed and connected with the driven gear. The diameter of the driving gear is one-fifth of the diameter of the driven gear, making the driving force of the driving gear driving the driven gear smaller, thereby expanding the torque and increasing the force of the limit rod pressing against the electricity meter box, making the pressing and fixing force of the installed electricity meter box greater. When the driving gear rotates, the driven gear rotates, causing the toothed rod to start moving. The toothed rod pushes the linkage telescopic rod to rotate, causing the limit rod to rotate and press against and fit on the inner wall of the electricity meter box, thereby making the installation of the electricity meter more convenient.

[0010] Further, an anti-theft lock is arranged on the inner wall of the electricity meter box near the driving gear. A transmission rod is fixedly installed at one end of the anti-theft lock of the anti-theft lock, and the transmission rod is fixedly installed at the upper end of the driving gear away from the anti-theft lock. A sliding frame is fixedly installed on the inner wall of the electricity meter box near the toothed rod. A limit block is slidably arranged at the side end of the sliding frame. The limit block blocks the movement of the toothed rod 211 under normal circumstances. Therefore, the limit block needs to be moved first before using the key to rotate the driving gear, thereby increasing the anti-theft performance of the electricity meter.

[0011] Furthermore, a limiting rope is fixedly installed at the side end of the limiting block. One end of the limiting rope away from the limiting block is fixedly installed with a moving block, and the moving block is slidably installed at the lower end of the meter box. When it is necessary to disassemble and replace the meter, insert the key, press the moving block, and the limiting rope pulls the limiting block to start moving, causing the limiting block to compress the limiting spring, so that the key can be rotated to disassemble the meter.

[0012] Furthermore, the trigger alarm mechanism includes a detection rod. One end of the detection rod is fixedly installed with a threaded head, and the threaded head is threadedly installed on the inner wall of the limiting rod. The end of the detection rod away from the threaded head is threadedly installed with a connecting head. When the meter is violently removed, the vibration amplitude of the detection rod is greater than the thickness of the rubber sleeve, causing one end of the detection rod to collide with the limiting rod, resulting in the disconnection of the detection rod. And both ends of the detection rod are provided in a threaded connection state, so that it is more convenient to replace the new detection rod after the detection rod is disconnected.

[0013] Furthermore, a control rope is tied to the end of the connecting head away from the detection rod. One end of the control rope away from the connecting head is fixedly connected with a sliding block. One end of the meter box close to the sliding block is fixedly installed with a sliding rail, and the sliding block is slidably installed on the upper end of the sliding rail. A touch block is fixedly installed on the side end of the sliding block. After the detection rod 301 is disconnected, the control rope no longer pulls to restrict the movement of the sliding block, and the control spring 308 pulls the sliding block 306 to move, so that the touch block 309 can trigger the alarm more quickly.

[0014] Furthermore, a storage battery is fixedly installed on the inner wall of the meter box. The input end of the storage battery is fixedly installed with a charger. The input end of the charger is fixedly installed with a charging wire, and the charging wire is fixedly installed on the output end of the relay. The output end of the storage battery is fixedly installed with an output wire. One end of the output wire away from the storage battery is fixedly installed with a touch switch, and the touch switch is fixedly installed on the inner wall of the meter box close to the touch block. One end of the touch switch away from the output wire is fixedly installed with an alarm. The charging wire connected to the output end of the relay charges the storage battery, so that the power of the storage battery is always in a normal state. Even if a thief cuts the wire and wants to violently remove the meter box, the storage battery can still provide power for the alarm.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In the present invention, a baffle strip is fixedly welded in the meter box. When installing the meter box, the limiting rod rotatably arranged at the side end of the meter box is rotatably supported between the baffle strips. The limiting rod makes it impossible for thieves to easily disassemble the meter. And at the same time, once the meter box is violently removed, the detection rod in the limiting rod breaks, and the control spring pulls the sliding block to move, so that the touch block contacts the touch switch, the touch switch is turned on, and the meter emits an alarm, thereby strengthening the anti-theft function;

[0017] 2. By inserting the key and pressing the moving block, the limiting rope pulls the limiting block to move. Rotating the key makes the driving gear rotate, and the driven gear rotates, causing the toothed rod to start moving. The toothed rod pushes the linkage telescopic rod to rotate, and the limiting rod rotates and presses against the inner wall of the meter box, making the installation of the meter more convenient.

[0018] 3. When the detection rod is damaged and needs to be replaced, remove the limiting rod, use a tool to rotate the detection rod remaining inside, and then thread-mount the new detection rod into the limiting rod, making the replacement of the detection rod more convenient.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 to 8 , an electric meter structure with mechanical anti-theft function, including an electric meter box 1. An electric meter box 101 is placed inside the electric meter box 1. One end of the electric meter box 101 is provided with a connection line and an electric meter 102 for displaying the electricity consumption. The above-mentioned electric meter 102 is a prior art and will not be elaborated here. The electric meter 102 converts the accessed electric energy into mechanical energy or other forms of signals through an internal measurement mechanism. After processing and calculation, the electricity consumption is displayed in the form of numbers or pointers. One end of the electric meter 102 is provided with a display screen, and the display screen is fixedly installed on the side end of the electric meter box 1. A box cover 103 is rotatably installed on the side end of the electric meter box 1. The above-mentioned box cover 103 is set as an explosion-proof transparent glass cabinet door, which makes it more convenient for the staff to observe the electricity consumption displayed on the electric meter 102 through the box cover 103. A sealing ring 104 is fixedly installed at the edge of the electric meter box 1. After installation, when the box cover 103 is closed, the electric meter box 1 and the box cover 103 squeeze the sealing ring 104 to seal the electric meter box 1, playing a role in moisture-proof. A limit mechanism 2 for mechanical anti-theft is provided inside the electric meter box 101 close to the electric meter 102. Specifically, the electric meter box 101 is restricted and fixed in the electric meter box 1 through a mechanical structure, so that thieves cannot take it out, playing an anti-theft role. At the same time, the limit mechanism 2 makes the installation of the electric meter box 101 more convenient. A trigger ringing mechanism 3 for sounding an alarm when the electric meter is illegally stolen is provided between the limit mechanism 2 and the electric meter 102. Specifically, after the electric meter box 101 is violently damaged through a fragile structure, the electric meter box 101 emits an alarm, thereby strengthening the anti-theft function.

[0035] Please refer to Figures 1 to 3, the limiting mechanism 2 includes an installation ring 201, and the installation ring 201 is arranged at the corner of the meter box 101. There is a vacancy at the corner of the meter box 101 close to the installation ring 201, and the installation ring 201 is arranged in an arc shape, and the arc opening fits the size of the vacancy provided in the meter box 101. A rotating rod 202 is rotatably arranged on the inner wall of the installation ring 201, and a sealing bearing 203 is arranged between the rotating rod 202 and the installation ring 201. The above-mentioned sealing bearing 203 is a prior art. Since the sealing bearing 203 can effectively prevent external substances from entering and lubricant leakage, reduce the wear of the bearing and the probability of failure, thereby reducing the maintenance cost and downtime of the equipment, the sealing bearing 203 plays a role of moisture-proof sealing. A limiting rod 204 is fixedly installed at the side end of the rotating rod 202 away from the meter box 101, and a limiting plate 205 is rotatably installed at one end of the limiting rod 204 away from the rotating rod 202. Anti-slip sheets 206 are arranged on the surface of the limiting plate 205. The above-mentioned anti-slip sheets 206 are made of PVC material and have unique textures on the surface, which can increase friction, be waterproof, anti-slip, dust-proof, fire-proof and insulating. After the anti-slip sheets 206 make the limiting plate 205 fit on the inner wall of the meter box 1, it can prevent the meter box 1 from slipping. A baffle strip 207 is fixedly welded at one end of the meter box 1 close to the limiting plate 205. The baffle strip 207 makes the limiting rod 204 rotatably supported in the meter box 1, and the meter box 101 is not easily taken out. Specifically, when installing the meter box 101, rotate the limiting rod 204 to make the limiting plate 205 arranged at one end of the limiting rod 204 squeeze and fit on the inner wall of the meter box 1, so that there is no need for other bolts to fix the meter box 101, making the installation of the meter box 101 more convenient.

[0036] Please refer to Figures 1 to 3, a push rod 208 is rotatably installed at one end of the rotating rod 202 away from the limit rod 204, and a linkage telescopic rod 209 is rotatably installed at one end of the pushing rod 208 away from the rotating rod 202. The above-mentioned linkage telescopic rod 209 is a prior art and will not be described in detail here. When the linkage telescopic rod 209 starts to rotate, the pushing rod 208 makes an arc motion, so that the linkage telescopic rod 209 starts to extend, so as to avoid the linkage telescopic rod 209 being pulled and damaged, and a rotating rod 210 is slidably provided at one end of the linkage telescopic rod 209 close to the pushing rod 208. When the linkage telescopic rod 209 drives the pushing rod 208 to rotate, the lever prying end of the linkage telescopic rod 209 can be kept in a suitable position, and the rotating rod 210 is rotatably installed on the inner wall of the meter box 101. When the sliding rotating rod 210 causes the linkage telescopic rod 209 to rotate, the linkage telescopic rod 209 rotates around the rotating rod 210, and the rotating rod 210 uses the lever principle to rotate the linkage telescopic rod 209 to drive the rotating rod 202 to rotate. The force is greater, the end of the linkage telescopic rod 209 away from the push rod 208 is rotatably installed with a gear rod 211, and the gear rod 211 is slidably installed on the inner wall of the meter box 1. When the gear rod 211 moves, the gear rod 211 pushes the linkage telescopic rod 209 to rotate, and the inner wall of the meter box 101 close to the gear rod 211 is rotatably installed with a driving gear 212, and the driving gear 212 is meshed and connected with a driven gear 213, and the diameter of the above-mentioned driving gear 212 is one fifth of the diameter of the driven gear 213 , so that the driving gear 212 drives the driven gear 213 to rotate with less force, thereby expanding the torque, increasing the force of the limit rod 204 squeezing the meter box 1, and the gear rod 211 is meshed and connected with the driven gear 213. Specifically, when the driving gear 212 rotates, the driven gear 213 rotates, causing the gear rod 211 to start moving, and the gear rod 211 pushes the linkage telescopic rod 209 to rotate so that the limit rod 204 rotates and is squeezed and fitted on the inner wall of the meter box 1, thereby making the installation of the meter more convenient.

[0037] See also Figures 1 to 5, an anti-theft lock 214 is provided on the inner wall of the meter box 101 close to the driving gear 212. The above anti-theft lock 214 is a prior art and will not be elaborated here. When the staff inserts the key and turns the key, the lock core of the anti-theft lock 214 starts to rotate. One end of the lock core of the anti-theft lock 214 is fixedly installed with a transmission rod 215, and the end of the transmission rod 215 away from the anti-theft lock 214 is fixedly installed on the outer wall of the driving gear 212. When the anti-theft lock 214 is turned with the key, the anti-theft lock 214 rotates, and drives the driving gear 212 to rotate through the transmission rod 215. A sliding frame 216 is fixedly installed on the inner wall of the meter box 101 close to the rack 211. A limiting block 217 is slidably arranged at the side end of the sliding frame 216. A protruding block is provided on the inner wall of the meter box 101 close to the sliding frame 216, and a limiting spring 218 is fixedly installed between the limiting block 217 and the protruding block provided on the meter box 101. The limiting spring 218 enables the limiting block 217 to block the movement of the rack 211 under normal circumstances, so that the limiting block 217 needs to be moved first before turning the driving gear 212 with the key, thereby increasing the anti-theft performance of the meter.

[0038] Please refer to Figures 1 to 5 , a limiting rope 219 is fixedly installed at the side end of the limiting block 217. A plurality of guide rods are provided on the inner wall of the meter box 101 close to the limiting rope 219. The guide rods change the moving direction of the limiting rope 219. One end of the limiting rope 219 away from the limiting block 217 is fixedly installed with a moving block 220. When the moving block 220 is pressed, the moving block 220 pulls the limiting block 217 to move through the limiting rope 219, and the moving block 220 is slidably installed at the lower end of the meter box 101. Specifically, when it is necessary to disassemble and replace the meter, insert the key, press the moving block 220, and the limiting rope 219 pulls the limiting block 217 to start moving, so that the limiting block 217 compresses the limiting spring 218, and then the key can be turned to disassemble the meter.

[0039] Please refer to Figures 1 to 8The trigger alarm mechanism includes a detection rod 301. The detection rod 301 is set as a carbon rod in the prior art. The carbon rod has good chemical stability, strong acid resistance, and does not react with strong acid, but has poor alkali resistance at high temperature, which will corrode and decompose the rod body. It has a hard and brittle texture, a small expansion coefficient, can withstand rapid cooling and heating, and is not easy to deform. A rubber sleeve 302 is sleeved on the outer wall of the detection rod 301. The rubber sleeve 302 prevents the detection rod 301 from being disconnected during the installation and transportation of the electric meter by the staff, so that the detection rod 301 will not be disconnected when it vibrates slightly. When the electric meter is violently dismantled, the vibration amplitude of the detection rod 301 is greater than the thickness of the rubber sleeve 302, so that one end of the detection rod 301 is in contact with the limit rod 204 collides, causing the detection rod 301 to break. One end of the detection rod 301 is fixedly installed with a threaded head 303, and the threaded head 303 is threadedly installed on the inner wall of the limiting rod 204. The end of the detection rod 301 away from the threaded head 303 is threadedly installed with a connecting head 304. The above-mentioned connecting head 304 is configured to be a threaded bolt, and the connecting head 304 is threadedly installed on the inner wall of the limiting rod 204. After the detection rod 301 is broken, when a new detection rod 301 needs to be replaced, it is only necessary to fix the new detection rod 301 in the connecting head 304, and insert the connecting head 304 into the inside of the limiting rod 204 and thread it, so that it is more convenient to replace the new detection rod 301 after the detection rod 301 is broken.

[0040] See also Figures 1 to 8 The end of the connector 304 away from the detection rod 301 is tied with a control rope 305. The control rope 305 is an ultra-high molecular weight polyethylene fiber rope in the prior art. The rope of this material has extremely high wear resistance, impact resistance and low temperature resistance. Its strength is several times that of ordinary nylon ropes. It can adapt to various harsh use environments and is widely used in outdoor sports, industrial lifting and other fields, so that the control rope 305 can be used for a long time. The end of the control rope 305 away from the connector 304 is fixedly connected with a sliding block 306. The end of the meter box 101 close to the sliding block 306 is fixedly installed with a sliding rail 307, and the sliding block 306 is slidably installed. At the upper end of the sliding rail 307, the sliding rail 307 is set in an "I" shape, and a groove that fits the sliding rail 307 is opened at one end of the sliding block 306 close to the sliding rail 307, so that the sliding block 306 can slide stably on the surface of the sliding rail 307 without falling off, and a control spring 308 is fixedly installed between the sliding rail 307 and the sliding block 306, and a touch block 309 is fixedly installed on the side end of the sliding block 306. When the detection rod 301 is disconnected, the control rope 305 no longer pulls to limit the movement of the sliding block 306, and the control spring 308 pulls the sliding block 306 to move, so that the touch block 309 triggers the alarm more quickly.

[0041] See also Figures 1 to 8, a storage battery 315 is fixedly installed on the inner wall of the meter box 101. The above storage battery 315 is a lead-acid battery in the prior art: made of lead and sulfuric acid, with lead dioxide as the positive electrode and flocculent lead as the negative electrode. Its advantages are low price, mature technology, and high reliability. The input end of the storage battery 315 is fixedly installed with a charger 310. The above charger 310 is a prior art and will not be elaborated here. After the meter box 101 is powered on, the charger 310 works to charge the storage battery 315. The input end of the charger 310 is fixedly installed with a charging wire 311, and the charging wire 311 is fixedly installed at the output end of the relay 102. The storage battery 315 is charged through the charging wire 311 connected to the output end of the relay 102, so that the power of the storage battery 315 is always in a normal state. Even if a thief cuts the wire and wants to violently remove the meter box 101, the storage battery 315 can still provide power for the alarm device. The output end of the storage battery 315 is fixedly installed with an output wire 312. One end of the output wire 312 away from the storage battery 315 is fixedly installed with a touch switch 313. The above touch switch 313 is a prior art and will not be elaborated here. When the touch block 309 contacts the touch switch 313, the touch switch 313 is turned on. When the touch block 309 does not contact the touch switch 313, the touch switch 313 is turned off. And the touch switch 313 is fixedly installed on the inner wall of the meter box 101 close to the touch block 309. One end of the touch switch 313 away from the output wire 312 is fixedly installed with an alarm 314. The above alarm 314 is a multi-functional alarm in the prior art, with functions such as anti-theft, anti-theft of electricity, help seeking, fire prevention, and prevention of poisoning by combustible gases. Once an alarm occurs, the host automatically dials the set phone numbers in a loop and emits a voice alarm signal. When the touch block 309 contacts the touch switch 313, the touch switch 313 is turned on, and the alarm 314 is powered on and starts to work to emit an alarm.

[0042] The working principle of the present invention is: when installing the electric meter, open the box cover 103, put the meter box 101 into the meter box 1, insert the key, press the moving block 220, the limiting rope 219 pulls the limiting block 217 to move, turn the key, the driving gear 212 rotates, the driven gear 213 rotates, so that the toothed rod 211 starts to move, the toothed rod 211 pushes the linkage telescopic rod 209 to rotate, the linkage telescopic rod 209 rotates around the rotating rod 210, drives the pushing rod 208 to start to move, makes the rotating rod 202 start to rotate, and the rotating rod 202 drives the limiting rod 204 to rotate and press against the inner wall of the meter box 1, thereby making the installation of the electric meter more convenient;

[0043] When the box door is violently removed, the detection rod 301 is disconnected, the control rope 305 no longer restricts the movement of the sliding block 306, the control spring 308 pulls the sliding block 306 to move, the touch block 309 contacts the touch switch 313, the touch switch 313 is turned on, the alarm 314 is powered on, and the alarm 314 starts to work to emit an alarm, thereby strengthening the anti-theft function of the electric meter;

[0044] Meanwhile, when a thief unlocks the lock to steal electricity from the electricity meter without pressing the moving block 220, the limiting block 217 blocks the movement of the rack 211, so that the driven gear 213 and the driving gear 212 restrict the lock core of the anti-theft lock 214, making the lock core of the anti-theft lock 214 unable to rotate, playing a role in strengthening anti-theft.

[0045] When the detection rod 301 is damaged and needs to be replaced, the limiting rod 204 is disassembled, and the internally retained detection rod 301 is rotated with a tool, and then the new detection rod 301 is rotated and threadedly installed in the limiting rod 204, so that the replacement of the detection rod 301 is more convenient.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
