[0006] According to an embodiment of the present invention, a low-voltage cable branch box with anti-theft function includes: a cable box, a cabinet door, the cabinet door being rotatably mounted on the inner wall of the cable box; a circuit breaker, the circuit breaker being disposed on the inner wall of the cable box; a copper busbar, the copper busbar being disposed on the inner wall of the cable box; a protective cover is fixedly installed on the inner wall of the cable box, and an elastic telescopic plate is fixedly installed on the inner wall of the protective cover; a sliding plate is fixedly installed on the free end of the elastic telescopic plate; a fixing block is fixedly installed on the surface of the sliding plate; a push block is slidably installed on the inner wall of the cable box; a trapezoidal plate is fixedly installed on the surface of the push block; the trapezoidal plate is disposed above the fixing block; a short plate is fixedly installed on the top of the trapezoidal plate; a trapezoidal frame is slidably installed on the inner wall of the cable box; an L-shaped frame is fixedly installed on the top of the trapezoidal frame; when the trapezoidal plate moves away from the sliding plate, it will disengage from the limiting position of the fixing block, and then the elastic force of the elastic telescopic plate itself will drive the sliding plate to reset, after which maintenance can be performed.

[0007] In some embodiments of the present invention, a first spring is provided between the cable box and the push block, and the push block is reset by the elastic force of the first spring itself. A second spring is provided between the cable box and the trapezoidal frame, and the trapezoidal frame is reset by the elastic force of the second spring itself.

[0008] In some embodiments of the present invention, the cable box is equipped with a monitoring device and a protection device for preventing electricity theft. The monitoring device includes a dustproof plate, an L-shaped plate, a sealing plate, and a scraper. When the sliding plate moves upward, it drives the L-shaped plate to move upward. The upward movement of the L-shaped plate drives the sealing plate to move upward. The upward movement of the sealing plate drives the scraper to move upward. A heat dissipation groove is formed on the surface of the cable box. The dustproof plate is fixedly installed on the inner wall of the heat dissipation groove. The L-shaped plate is fixedly installed on the surface of the sliding plate. The sealing plate is fixedly installed on the surface of the L-shaped plate. The scraper is fixedly installed on the surface of the sealing plate.

[0009] In some embodiments of the present invention, a fixing rod is fixedly installed on the surface of the cabinet door, an L-shaped sliding plate is slidably installed on the inner wall of the cable box, a monitoring lens is provided on the surface of the protective cover, and a baffle is fixedly installed on the surface of the L-shaped sliding plate. When the L-shaped sliding plate resets, it will drive the baffle to reset, and the baffle will disengage from the seal on the monitoring lens.

[0010] In some embodiments of the present invention, a No. 3 spring is provided between the cable box and the L-shaped sliding plate, and a rubber ring is provided on the surface of the baffle.

[0011] In some embodiments of the present invention, the protection device includes an L-shaped slider, a connecting plate, and a trapezoidal push plate. The L-shaped slider is pushed upward by the upward movement of the sliding plate, which in turn drives the connecting plate upward, and the connecting plate upward drives the trapezoidal push plate upward. A trip button is provided on the surface of the circuit breaker. The L-shaped slider is slidably mounted on the inner wall of the protective cover. The connecting plate is fixedly mounted on the top of the L-shaped slider. The trapezoidal push plate is fixedly mounted on the top of the connecting plate. The trip button is located below the trapezoidal push plate.

[0012] In some embodiments of the present invention, a long plate is fixedly installed on the surface of the connecting plate, a vertical plate is fixedly installed on the top of the long plate, a fixed seat is fixedly installed on the surface of the protective cover, a rotating plate is rotatably installed on the inner wall of the fixed seat, and a connecting rod is fixedly installed on the surface of the rotating plate. When the long plate moves upward, it will drive the vertical plate to move upward. When the vertical plate moves upward, it will push the connecting rod to rotate upward. When the connecting rod rotates upward, it will drive the rotating plate to rotate downward.

[0013] In some embodiments of the present invention, a No. 4 spring is provided between the L-shaped slider and the protective cover, and the L-shaped slider is reset by the elastic force of the No. 4 spring itself. A No. 1 torsion spring is provided between the fixed seat and the rotating plate, and the rotating plate is reset by the elastic force of the No. 1 torsion spring itself.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention uses a protective cover and sliding plate to block the copper busbar, preventing unauthorized access and power theft. A hidden push block effectively prevents unauthorized personnel from opening the sliding plate to steal electricity. When the short plate and trapezoidal frame reset, the elasticity of the second spring causes the trapezoidal frame to reset, limiting the short plate. This eliminates the need to constantly push the push block, making operation more convenient and ensuring equipment safety. Moving the sliding plate upwards pushes the L-shaped frame upwards, which in turn moves the trapezoidal frame upwards. Once the trapezoidal frame moves upwards, it releases the limitation on the short plate, causing the push block and trapezoidal plate to automatically reset. To close the sliding plate, simply push it downwards.

[0015] This invention involves the sliding plate moving upwards, which in turn moves the L-shaped plate upwards. The L-shaped plate then moves the sealing plate upwards, which in turn moves the scraper upwards. The scraper removes impurities and dust adhering to the dustproof plate, preventing dust from clogging the dustproof plate and affecting the heat dissipation of the equipment. At the same time, the baffle resetting releases the seal on the monitoring lens, allowing the camera to monitor personnel opening the cabinet door in real time, preventing unauthorized personnel from opening the cabinet door to steal electricity and affecting the normal use of the equipment.

[0016] This invention uses a trapezoidal push plate to actuate the trip button, disconnecting the circuit breaker and preventing the circuit breaker from being forgotten to be turned off during maintenance when the sliding plate is open, thus avoiding safety hazards. Simultaneously, the upward rotation of the connecting rod causes the rotating plate to rotate downward, blocking the circuit breaker and preventing the user from turning on the circuit breaker when the sliding plate is open, which could easily lead to an accident. When the sliding plate is closed, the elastic force of the first torsion spring will cause the rotating plate to return to its original position, allowing the user to turn on the circuit breaker, thus improving safety during maintenance.

[0019] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] like Figure 1 - Figure 7As shown, one embodiment of the present invention is: a low-voltage cable branch box with anti-theft function, comprising: a cable box 1, a cabinet door 2, the cabinet door 2 being rotatably installed on the inner wall of the cable box 1; a circuit breaker 3, the circuit breaker 3 being disposed on the inner wall of the cable box 1; a copper busbar 4, the copper busbar 4 being disposed on the inner wall of the cable box 1; a protective cover 7 being fixedly installed on the inner wall of the cable box 1, and an elastic telescopic plate 5 being fixedly installed on the inner wall of the protective cover 7, a sliding plate 6 being fixedly installed on the free end of the elastic telescopic plate 5, a fixing block 8 being fixedly installed on the surface of the sliding plate 6, a push block 10 being slidably installed on the inner wall of the cable box 1, a trapezoidal plate 9 being fixedly installed on the surface of the push block 10, the trapezoidal plate 9 being disposed above the fixing block 8, a short plate 11 being fixedly installed on the top of the trapezoidal plate 9, a trapezoidal frame 12 being slidably installed on the inner wall of the cable box 1, and an L-shaped frame 13 being fixedly installed on the top of the trapezoidal frame 12. By concealing the push block 10, it is possible to effectively prevent unauthorized personnel from opening the sliding plate 6 to steal electricity.

[0021] A first spring is installed between the cable box 1 and the push block 10. The push block 10 is reset by the elastic force of the first spring. A second spring is installed between the cable box 1 and the trapezoidal frame 12. The trapezoidal frame 12 is reset by the elastic force of the second spring.

[0022] In this embodiment, the copper busbar 4 is blocked by the protective cover 7 and the sliding plate 6 to prevent unauthorized access and power theft. When it is necessary to open the sliding plate 6, the push block 10 is first pushed away from the sliding plate 6. This movement of the push block 10 will cause the trapezoidal plate 9 to move away from the sliding plate 6. The movement of the trapezoidal plate 9 away from the sliding plate 6 will disengage it from the limiting position of the fixed block 8. Subsequently, the elastic force of the elastic telescopic plate 5 will cause the sliding plate 6 to reset, allowing for maintenance. By concealing the push block 10, unauthorized personnel can be prevented from opening the sliding plate 6 to steal electricity. At the same time, the movement of the trapezoidal plate 9 away from the sliding plate 6 will cause the short plate 11 to move away from the sliding plate 6. When the short plate 11 moves away from the sliding plate 6, it will contact the inclined surface of the trapezoidal frame 12. The short plate 11 will push the trapezoidal frame 12 upward. After the short plate 11 and the trapezoidal frame 12 are reset, the elastic force of the second spring will drive the trapezoidal frame 12 to reset. The reset of the trapezoidal frame 12 will limit the short plate 11, eliminating the need to constantly push the push block 10 by hand, making operation more convenient and ensuring the safety of equipment use. At the same time, when the sliding plate 6 moves upward, it will push the L-shaped frame 13 upward. The upward movement of the L-shaped frame 13 will drive the trapezoidal frame 12 upward. After the trapezoidal frame 12 moves upward, it will release the limit on the short plate 11, causing the push block 10 and the trapezoidal plate 9 to automatically reset. When it is necessary to close the sliding plate 6, simply push the sliding plate 6 downward.

[0023] Please see Figure 1 - Figure 7Based on the above embodiments, in another embodiment of the present invention, a monitoring device and a protection device for preventing electricity theft are provided inside the cable box 1. The monitoring device includes a dustproof plate 141, an L-shaped plate 142, a sealing long plate 143, and a scraper 144. A heat dissipation groove is opened on the surface of the cable box 1. The dustproof plate 141 is fixedly installed on the inner wall of the heat dissipation groove. The L-shaped plate 142 is fixedly installed on the surface of the sliding plate 6. The sealing long plate 143 is fixedly installed on the surface of the L-shaped plate 142. The scraper 144 is fixedly installed on the surface of the sealing long plate 143. By moving the scraper 144 upward, the impurities and dust adhering to the dustproof plate 141 are scraped off, preventing the dust from clogging the dustproof plate 141 and affecting the heat dissipation effect of the equipment.

[0024] A fixing rod 145 is fixedly installed on the surface of cabinet door 2, an L-shaped sliding plate 146 is slidably installed on the inner wall of cable box 1, a monitoring camera 147 is installed on the surface of protective cover 7, and a baffle 148 is fixedly installed on the surface of L-shaped sliding plate 146, so that the monitoring camera 147 can monitor the person who opens cabinet door 2 in real time, preventing unauthorized personnel from opening cabinet door 2 to steal electricity and affect the normal use of equipment.

[0025] A No. 3 spring is installed between the cable box 1 and the L-shaped slide plate 146, and a rubber ring is installed on the surface of the baffle 148.

[0026] In this embodiment, when the sliding plate 6 moves upward, it drives the L-shaped plate 142 to move upward. The upward movement of the L-shaped plate 142 drives the sealing plate 143 to move upward. The upward movement of the sealing plate 143 drives the scraper 144 to move upward. The upward movement of the scraper 144 scrapes off the impurities and dust adhering to the dustproof plate 141, preventing the dust from clogging the dustproof plate 141 and affecting the heat dissipation of the equipment. At the same time, when the cabinet door 2 is opened, the rotation of the cabinet door 2 will drive the fixing rod 145 to rotate. The rotation of the fixing rod 145 will release the pressure on the L-shaped sliding plate 146, allowing the elastic force of the No. 3 spring to drive the L-shaped sliding plate 146 to reset. The reset of the L-shaped sliding plate 146 will drive the baffle 148 to reset. The reset of the baffle 148 will release the seal on the monitoring lens 147, allowing the monitoring lens 147 to monitor the person opening the cabinet door 2 in real time, preventing unauthorized personnel from opening the cabinet door 2 to steal electricity and affect the normal use of the equipment.

[0027] The protection device includes an L-shaped slider 151, a connecting plate 152, and a trapezoidal push plate 153. A trip button is provided on the surface of the circuit breaker 3. The L-shaped slider 151 is slidably mounted on the inner wall of the protective cover 7. The connecting plate 152 is fixedly mounted on the top of the L-shaped slider 151. The trapezoidal push plate 153 is fixedly mounted on the top of the connecting plate 152. The trip button is located below the trapezoidal push plate 153. When the trapezoidal push plate 153 moves upward, its inclined surface will contact the trip button, and the trapezoidal push plate 153 will push the trip button to disconnect the circuit breaker 3. This prevents the circuit breaker 3 from being forgotten to be turned off when the sliding plate 6 is opened for maintenance, thus avoiding potential safety hazards.

[0028] A long plate 154 is fixedly installed on the surface of the connecting plate 152, and a vertical plate 155 is fixedly installed on the top of the long plate 154. A fixed seat 156 is fixedly installed on the surface of the protective cover 7. A rotating plate 157 is rotatably installed on the inner wall of the fixed seat 156. A connecting rod 158 is fixedly installed on the surface of the rotating plate 157. The rotating plate 157 rotates downward to block the circuit breaker 3, preventing the user from opening the circuit breaker 3 when the sliding plate 6 is open, which could easily lead to an accident.

[0029] A No. 4 spring is provided between the L-shaped slider 151 and the protective cover 7. The L-shaped slider 151 is reset by the elastic force of the No. 4 spring. A No. 1 torsion spring is provided between the fixed seat 156 and the rotating plate 157. The rotating plate 157 is reset by the elastic force of the No. 1 torsion spring.

[0030] The upward movement of the sliding plate 6 pushes the L-shaped slider 151 upward, which in turn moves the connecting plate 152 upward. This, in turn, moves the trapezoidal push plate 153 upward. The upward movement of the trapezoidal push plate 153 causes its inclined surface to contact the trip button, which then pushes the trip button, disconnecting the circuit breaker 3. This prevents the circuit breaker 3 from being forgotten to be turned off during maintenance when the sliding plate 6 is open, thus avoiding potential safety hazards. Simultaneously, the upward movement of the connecting plate 152 also causes the long plate 154 to move upward. The upward movement of the long plate 154 will cause the vertical plate 155 to move upward. The upward movement of the vertical plate 155 will push the connecting rod 158 to rotate upward. The upward rotation of the connecting rod 158 will cause the rotating plate 157 to rotate downward. The downward rotation of the rotating plate 157 will block the circuit breaker 3, preventing the user from opening the circuit breaker 3 when the sliding plate 6 is open, which could easily lead to an accident. When the sliding plate 6 is closed, the elastic force of the first torsion spring will drive the rotating plate 157 to reset, allowing the user to open the circuit breaker 3, thus improving safety during maintenance.
