[0001] This invention relates to the field of electricity metering box technology, and in particular to a spring-loaded anti-accidental-touch electricity metering box. Background Technology

[0002] Electricity metering boxes are key equipment in power distribution systems and are widely used in residential, industrial, and commercial electricity metering. During routine maintenance, repair, or meter reading, operators may inadvertently touch live parts, posing a risk of electric shock.

[0003] Existing metering boxes mostly use simple fixed insulating partitions for basic shielding, which only achieves basic isolation and provides limited protection. Furthermore, the long-term close contact with and coverage of electrical components severely hinders heat dissipation, leading to localized heat accumulation. At the same time, it easily accumulates moisture and dust, accelerating insulation aging. When there are unused meter slots in the box without meters installed, the exposed wiring terminals or conductive parts lack effective physical isolation, further increasing the risk of accidental contact. Summary of the Invention

[0004] To overcome the shortcomings of fixed insulating partitions, such as poor performance, heat accumulation due to long-term contact with electrical components, and lack of effective isolation for exposed terminals, this invention provides a spring-loaded anti-accidental contact energy metering box.

The fixed rod is slidably connected to the adjacent sliding frame. Symmetrically distributed trigger springs are fixed inside the housing. The other end of the trigger spring is in a limiting sliding engagement with the sliding frame. Uniformly distributed limiting rods are slidably connected inside the housing. The limiting rods are in limiting contact engagement with the adjacent trigger springs. A limiting gear is rotatably connected inside the housing. The limiting gear and the adjacent uniformly distributed limiting rods are all engaged through gear transmission.

[0007] Furthermore, the deformation section of the trigger spring is provided with a slow-release arc-shaped bend to disperse deformation stress, avoid stress concentration, and extend the service life of the spring reciprocating.

[0008] Furthermore, the opening of the anti-accidental touch baffle is provided with a self-locking slot, and the self-locking slot of the anti-accidental touch baffle is equipped with a detachable shielding plate for sealing off and shielding vacant areas where no electricity meter is installed.

[0009] Furthermore, the triggering assembly includes symmetrically distributed trigger rods, all of which are rotatably connected to the housing. An elastic element is provided between the trigger rods and the housing. A contact plate is fixedly connected to the symmetrically distributed trigger rods. The contact plate contacts and engages with the housing door. The trigger rods are connected to the transmission assembly.

[0010] Furthermore, the transmission assembly includes a fixed ring rotatably connected to the trigger rod, a power gear rotatably connected to the trigger rod, an elastic element between the power gear and the fixed ring, a transmission gear rotatably connected inside the housing, the transmission gear meshing with the power gear, the transmission gear and the limiting gear being connected via a transmission belt, a limiting baffle rotatably connected inside the housing, an elastic element between the limiting baffle and the housing, and the limiting baffle engaging with the power gear for limiting.

[0011] Furthermore, the power gear is provided with a spiral-shaped limiting groove and a horizontal connecting groove, and the trigger rod is fixed with uniformly distributed limiting pins, which are in a limiting sliding fit with the limiting groove and the connecting groove in the power gear.

[0012] Furthermore, the secondary protection component includes evenly distributed adjusting rods, all of which are rotatably connected to the housing.

By adopting a spring-loaded linkage protection structure, the system achieves door-opening trigger protection and door-closing reset avoidance. Normally, no components are attached, ensuring good heat dissipation and ventilation, and avoiding heat and moisture accumulation. The trigger spring's slow-release arc-shaped bending disperses stress, resists fatigue, and increases service life and triggering stability. The triggering and supporting components provide buffering and positioning, reducing opening and closing impacts and component wear; the triggering component drives the protective mechanism as the door opens and closes, providing timely response, eliminating the need for electrical control, facilitating operation, and ensuring stable operation of electrical components.

Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Example 1

[0026] A spring-loaded anti-accidental contact energy metering box, such as Figure 1-8As shown, the device includes a housing 1, with a door 2 rotatably connected to the housing 1. Inside the housing 1 are an anti-accidental touch mechanism 3, a triggering component 4, and a secondary protection component 5 for limiting the position of the meter. The anti-accidental touch mechanism 3 protects the front of the meter from accidental touches except for the observation point. The triggering component 4 triggers the anti-accidental touch mechanism 3 to switch positions. The secondary protection component 5 protects the upper and lower surfaces of the meter from accidental touches. The anti-accidental touch protection mechanism includes a baffle assembly 31, a spring assembly 32, and a transmission assembly 33. The baffle assembly 31 includes an anti-accidental touch baffle 311, which is slidably connected to the spring assembly 32. The anti-accidental touch baffle 311 is equipped with... The meter has evenly distributed openings, and the openings on the anti-accidental touch baffle 311 correspond to the position of the meter. The openings on the anti-accidental touch baffle 311 are provided with self-locking slots, and the self-locking slots of the anti-accidental touch baffle 311 are equipped with detachable shielding plates 313. The shielding plates 313 are used to close the openings of the anti-accidental touch baffle 311 to prevent accidental insertion and contact with internal live parts, prevent misoperation or electric shock, and take into account dust prevention, foreign object prevention and safety isolation. The secondary protection component 5 includes evenly distributed wire baffles 501. The wire baffles 501 are slidably connected in the housing 1. Adjacent wire baffles 501 are set on the upper and lower sides of the meter. The wire baffles 501 and the anti-accidental touch baffle 311 cooperate to form an insulating isolation barrier.

[0027] like Figure 3 As shown, the spring assembly 32 includes a support beam 321 fixed to the housing 1, a sliding frame 322 slidably connected inside the housing 1, the sliding frame 322 being slidably connected to the support beam 321, a symmetrically distributed fixing rod 312 slidably connected inside the anti-accidental contact baffle 311, an elastic element (spring) being provided between the fixing rod 312 and the anti-accidental contact baffle 311, the fixing rod 312 being slidably connected to the adjacent sliding frame 322, and symmetrically distributed trigger springs 323 fixed inside the housing 1, the other end of the trigger spring 323 being in a limiting sliding engagement with the sliding frame 322. The deformation section of the trigger spring 323 is provided with a slow-release arc-shaped bend to disperse deformation stress, avoid stress concentration, and extend the service life of the spring. The housing 1 is slidably connected with evenly distributed limit rods 324. The limit rods 324 are in limiting contact with the adjacent trigger springs 323. The housing 1 is rotatably connected with limit gears 325. The limit gears 325 and the adjacent evenly distributed limit rods 324 are all connected through gear transmission. Through the elastic pressing force of the trigger springs 323, the anti-accidental contact baffle 311 is fitted and limited with the meter to prevent it from loosening or moving.

[0028] like Figure 4As shown, the trigger assembly 4 includes symmetrically distributed trigger rods 401 rotatably connected to the housing 1. An elastic element, which is a torsion spring, is provided between the trigger rods 401 and the housing 1. A contact plate 402 is fixedly connected to the symmetrically distributed trigger rods 401. The contact plate 402 contacts and engages with the housing door 2. The trigger rods 401 are connected to the transmission assembly 33. The external force action of the housing door is received through the contact plate 402. The linkage transmission structure completes the opening and closing trigger and limit unlocking, realizing the opening and closing switching and rapid response of the anti-accidental touch structure.

[0029] like Figure 4 and Figure 5 As shown, the transmission assembly 33 includes a fixed ring 331 rotatably connected to the trigger rod 401. A power gear 332 is rotatably connected to the trigger rod 401. An elastic element, which is a spring, is provided between the power gear 332 and the fixed ring 331. A transmission gear 333 is rotatably connected inside the housing 1. The transmission gear 333 meshes with the power gear 332. The transmission gear 333 is connected to the limiting gear 325 via a transmission belt. A limiting baffle 334 is rotatably connected inside the housing 1. An elastic element is provided between the limiting baffle 334 and the housing 1. The limiting baffle 334 engages with the power gear 332. The power gear 332 has a spiral limiting groove and a horizontal connecting groove. The trigger rod 401 is fixed with evenly distributed limiting pins 335. The limiting pins 335 engage with the limiting groove and the connecting groove in the power gear 332. By engaging with the limiting pins 335 in the limiting groove and the connecting groove in the power gear 332, the meshing state of the power gear 332 and the transmission gear 333 can be quickly switched, realizing the start / stop, mode switching and anti-accidental locking linkage of the spring assembly.

[0030] like Figure 7 As shown, the secondary protection component 5 includes evenly distributed adjusting rods 502 rotatably connected within the housing 1. The adjusting rods 502 have evenly distributed threaded protrusions, with adjacent threaded protrusions being symmetrically distributed. A transmission rod 503 is rotatably connected within the housing 1. The transmission rod 503 and the trigger rod 401 are driven by a transmission belt. Both the transmission rod 503 and the evenly distributed adjusting rods 502 are driven by transmission belts. The surface of the baffle plate 501 has evenly distributed insulating ribs, with arc-blocking grooves formed between adjacent insulating ribs. This increases the creepage distance and reduces the risk of short circuits and arcing. The adjusting rods 502 quickly move the baffle plate 501 to protect the terminals on both sides of the meter's loading and unloading, strengthening protection against accidental contact and misoperation, and improving the overall safety protection level.

[0031] like Figure 8As shown, it also includes a support assembly 6 for supporting and protecting the door 2. The support assembly 6 is disposed inside the box body 1. The support assembly 6 includes a base 601 that is fixed to the box body 1 and evenly distributed therein. A support seat 602 is rotatably connected to the base 601. A support rod 603 is slidably connected inside the support seat 602. An elastic element, which is a tension spring, is provided between the support rod 603 and the support seat 602. The support rod 603 is slidably engaged with the door 2. A limit spring 604 is provided inside the support rod 603 to limit... The spring clip 604 is in a limiting sliding engagement with the support base 602. The support base 602 has symmetrically distributed reset pins 605 that are slidably connected inside. The reset pins 605 are in contact with the limiting spring clip 604. The tension spring of the support rod 602 applies a closing force to the door 2, causing the door 2 to automatically return to its locked position to prevent the door from being accidentally opened. Then, the limiting spring clip 604 locks the support rod 603 in the extended position of the support base 602, fixing the opening and closing angle of the door 2 and preventing the door 2 from being accidentally closed or shaking during maintenance.

[0032] In the initial state, the metering box is normally closed, and the meter is in the working position. At this time, the box door 2 is fastened to the box body 1. In the trigger assembly 4, the trigger rod 401, under the torsion of the torsion spring, keeps the contact plate 402 in contact with the box door 2. In the transmission assembly 33, the fixing ring 331, under the action of the spring force, pushes the power gear 332 to maintain the uppermost position. The limit pin 335 on the trigger rod 401 is in the limit groove of the transmission gear 333. The power gear 332 and the transmission gear 333 are normally meshed. In the limit state of the limit baffle 334 and the box body 1, the power gear 332 is restricted to rotate counterclockwise. In the anti-accidental contact mechanism 3, the anti-accidental contact baffle 311 is in the retracted position to avoid contact with electrical components and affect heat dissipation. The fixing rod 312 in the baffle assembly 31, under the action of the spring force, keeps the contact plate 402 in contact with the box door 2. When the anti-accidental contact baffle 311 is extended outward, the fixed rod 312 and the sliding frame 322 are engaged, the trigger spring 323 is in the state of being squeezed and offset by the limit rod 324, and the free end of the trigger spring 323 drives the sliding frame 322 to be on the support beam 321 near the end of the box door 2. The limit gear 325 and the transmission gear 333 are engaged in transmission. The power gear 332 is limited by the limit baffle 334, so that the transmission gear 333 cannot rotate counterclockwise, thereby preventing the limit gear 325 from rotating counterclockwise and releasing the limit rod 324. In the secondary protection component 5, the baffle plate 501 is located on the upper and lower sides of the meter and is kept in a certain position to prevent the meter from contacting the wiring terminal and affecting heat dissipation. In the support component 6, the support rod 603 is kept retracted into the support seat 602 under the action of the tension spring.

[0033] When using and opening this metering box, the operator pulls the box door 2 outward. The box door 2 causes the contact plate 402 to rotate clockwise, which in turn causes the trigger rod 401 to rotate clockwise. The torsion spring of the trigger rod 401 further stores force, keeping the contact plate 402 in contact with the box door 2. The trigger rod 401 then causes the limit pin 335 on it to rotate synchronously.

[0034] When the limiting pin 335 is in a limiting state by the upper limiting groove of the drive gear 332, it drives the drive gear 332 to rotate clockwise. The drive gear 332 is limited by the limiting baffle 334 and cannot rotate clockwise. This causes the limiting pin 335 to slide upward in the limiting groove of the drive gear 332. The drive gear 332 is pushed downward by the limiting pin 335, and the spring between the drive gear 332 and the fixed ring 331 is compressed and stored until the limiting pin 335 enters the communicating groove of the drive gear 332. At this time, the drive gear 332 is disengaged from the transmission gear 331. The meshing transmission of 33 causes the transmission gear 333 to release from the limit of the adjacent limit rod 324, triggering the release of the elastic potential energy of the spring 323. This triggers the spring 323 to swing backward due to the elastic restoring force generated by the slow-release arc bending. The free end of the spring 323 drives the sliding frame 322 to slide along the support beam 321 towards the meter. The sliding frame 322 drives the anti-accidental contact baffle 311 to move synchronously through the fixed rod 312. The opening on the anti-accidental contact baffle 311 is aligned with the observation area of ​​the meter and forms a shield for the wiring area of ​​the meter.

[0035] As the trigger rod 401 rotates, it drives the transmission rod 503 to rotate via the transmission belt. The transmission rod 503 drives all the adjusting rods 502 to rotate simultaneously via multiple sets of rotating belts. The threaded protrusions on the adjusting rods 502 rotate synchronously, thereby driving the baffle plate 501 to move towards the upper and lower edges of the meter. The baffle plate 501 is in close contact with the upper and lower edges of the meter. The insulating ridges on the baffle plate 501 further increase the creepage distance between the terminals and reduce the risk of arcing. At the same time, the anti-accidental contact baffle plate 311 cooperates with the baffle plate 501 to form a complete insulation barrier.

[0036] During the opening of the door 2, the support rod 603 extends outward from the support base 602 under the action of the door 2. The support rod 603 drives the limiting spring 604 to move synchronously. The tension spring of the support rod 603 stretches and stores force, continuously applying an inward closing force to the door 2, preventing the door 2 from being forgotten to be closed after being temporarily opened, and achieving automatic reset and closure. When the door 2 is opened to the maximum position, the limiting spring 604 extends to both sides of the support rod 603 under the action of elasticity, and cooperates with the support base 602 to limit the movement of the support rod 603, preventing the support rod 603 from moving back into the support base 602 under the action of the tension spring, locking the support rod 603 in the extended position, providing support and positioning for the door 2, and preventing the door 2 from being accidentally closed or shaking after being opened by the operator.

[0037] After the door 2 is fully opened, the anti-accidental touch baffle 311 completely covers the meter and terminal area. If there is an empty meter position, the operator can insert the detachable shield 313 into the self-locking slot of the corresponding opening on the anti-accidental touch baffle 311 to achieve full enclosure and eliminate blind spots. At this time, the operator can safely perform maintenance or meter reading without accidentally touching live parts. If maintenance of the terminal is required, after the operator disconnects the power, the fixed rod 312 inside the anti-accidental touch baffle 311 can be pushed in opposite directions to release the fixed rod 312 from the sliding frame 322, and then the anti-accidental touch baffle 311 can be lifted to expose the meter and terminal area behind the anti-accidental touch baffle 311. At this time, the operator can perform maintenance and adjustment of the terminal.

[0038] When the operator closes the door 2, the reset pin 605 on the support seat 602 is pressed in advance. The reset pin 605 contacts the limiting spring 604 and retracts inward, so that the limiting spring 604 is released from the limiting state of the support seat 602, and the support seat 602 is released from the locked state. The support seat 602 can retract into the support seat 602 under the action of the tension spring. At the same time, the support seat 602 pulls the door 2 inward to close under the action of the elastic force of the tension spring, so as to prevent the door 2 from not closing tightly.

[0039] During the closing process of the door 2, the contact plate 402 remains in contact with the door 2 under the elastic force of the torsion spring of the trigger rod 401. The trigger rod 401 rotates counterclockwise, which drives the limit pin 335 to rotate counterclockwise. When the limit pin 335 rotates counterclockwise, it enters the spiral groove through the connecting groove of the drive gear 332. The drive gear 332 returns to its original position under the elastic force of the spring, resuming its meshing transmission with the transmission gear 333. The trigger rod 401 drives the drive gear 332 to rotate counterclockwise through the limit pin 335, and the drive gear 332 drives the transmission gear 333 clockwise. As the clock hand rotates, the transmission gear 333 drives the limit gear 325 to rotate via the transmission belt. The limit gear 325 drives the adjacent limit rod 324 to move simultaneously. The limit rod 324 gradually presses against the trigger spring 323, forcing the trigger spring 323 to bend and deform. The free end of the trigger spring 323 drives the sliding frame 322 to slide along the support beam 321 away from the meter. The sliding frame 322 drives the anti-misoperation baffle 311 to return to the initial position via the fixed rod 312, disengaging from the meter and wiring terminals, ensuring good heat dissipation and ventilation of the electrical components.

[0040] The trigger rod 401 drives the transmission rod 503 to rotate in the opposite direction, which in turn drives the adjusting rod 502 to rotate in the opposite direction. The threaded protrusion on the adjusting rod 502 drives the baffle plate 501 to move in the opposite direction at the same time, so that the baffle plate 501 returns to its initial position and is no longer in close contact with the upper and lower sides of the meter.

[0041] After the door 2 is fully closed, all mechanisms return to their initial closed state, the anti-accidental contact baffle 311 and the wire blocking plate 501 move away from the electrical components, and the metering box returns to normal operation. Thus, the metering box completes a full anti-accidental contact working cycle.

[0042] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
