[0006] As a further embodiment of the present invention, the bottom pressure block is located on the top of the top sheet, the bottom pressure block is pressed against the top of the top sheet, and the top sheet is an elastic metal sheet.

[0007] As a further embodiment of the present invention, a top block is fixedly connected to the bottom of two adjacent pressing blocks, and the top block is fixedly connected to the inner side of the baffle.

[0008] As a further embodiment of the present invention, a fixing block is fixedly connected to the center of the rear part of the wiring operation slot, and a double-opening fixing lock is fixedly connected to the center of the inner side of the cover. The locking beam of the double-opening fixing lock passes through the fixing block, and the lock hole of the double-opening fixing lock passes through the front part of the cover.

[0009] As a further embodiment of the present invention, the front part of the pressure block is inclined, the rear part of the lower pressure block is also inclined, and the angles of the inclined surfaces of the pressure block and the lower pressure block are complementary, and the bottom of the lower pressure block is in contact with the top of the pressure block.

[0010] As a further embodiment of the present invention, a tongue is fixedly connected to the bottom front of the cover, and a tongue groove is opened at the bottom front of the meter body, with the tongue and tongue groove being adaptively matched.

[0011] As a further embodiment of the present invention, the inner side of the shield is provided with four through slots extending through the outer side, and the positions of the four through slots correspond one-to-one with the positions of the four wiring components.

[0012] As a further embodiment of the present invention, a reset block is fixedly connected to the opposite side of each of the two adjacent bottom pressure blocks, and four fixing rods are fixedly connected inside the wiring operation slot. The fixing rods penetrate through the top of the reset block, and a spring is fixedly connected between the inside of the wiring operation slot and the bottom of the reset block and on the outer surface of the fixing rod.

[0013] As a further embodiment of the present invention, a limit block is fixedly connected to the top of the fixed rod, the spring is in a compressed state, a vertical block is fixedly connected to the rear part of the bottom of the top block, a top block is fixedly connected to the bottom of the front part of the vertical block, the front part of the top block is inclined, and the top block is located between two pressure blocks.

[0014] As a further embodiment of the present invention, a sealing block 1 is slidably connected to both sides of the inside of the wiring operation slot. A pair of wedge blocks 2 are fixedly connected to the side of the sealing block 1. A wedge block 1 is slidably connected to the inside of the wiring operation slot and in front of the wedge blocks 2. A fixing block is fixedly connected to the side of the pair of wedge blocks 1 on the same side. A rotating rod is rotatably connected between the two fixing blocks. A stop block is fixedly connected to the outer surface of the rotating rod and in front of the two fixing blocks. A pair of front blocks are symmetrically fixedly connected to the inside of the wiring operation slot and in front of the front. A straight groove is horizontally opened through the front and rear of the front of the front block. A support block is vertically fixedly connected to the outer surface of the rotating rod and in front of the straight groove. A pair of top fixing blocks are symmetrically connected to the top of the wiring operation slot. A sealing block 2 is slidably connected to the top of the pair of top fixing blocks. The bottom of the sealing block 2 is fixedly connected to the fixing block in the rear. The sealing block 1 is L-shaped.

[0015] The beneficial effects that can be achieved by the above embodiments of the present invention include: By setting up a complementary inclined extrusion method between the lower pressing block and the pressure receiving block in the fast pressing structure, the horizontal sliding of the baffle is transformed into the vertical pressing motion of the bottom pressing block. Without the need for additional tools or multiple independent operations, the wire can be firmly crimped by pushing the baffle in, which greatly simplifies the wiring process and improves the operating efficiency. By setting a double-locking mechanism that penetrates the cover and the internal fixing block, the physical locking state of the cover and the effective working state of the fast-pressing structure are deeply mechanically coupled. Only when the cover is correctly locked can the fast-pressing structure remain in the pressed position. Once the cover is illegally damaged or opened, the top block driven by it will be displaced, causing the fast-pressing structure to fail and the wire crimping to be released. This eliminates the possibility of electricity theft from the root of the physical linkage mechanism. By setting up an elastic reset mechanism consisting of a fixed rod, a reset block, and a compression spring, which is linked with the bottom pressure block and the connecting block, when it is necessary to repair or replace the line or remove the cover, as the bottom pressure block releases its restriction on the pressure block, the restoring force of the spring will immediately push the entire connecting block assembly to move upward and reset through the reset block, thereby automatically releasing the clamp on the wire by the top plate. This achieves automatic linkage between disassembling the protection and disconnecting the wiring, making maintenance work easy and quick. By setting a top block on the top block and its inclined surface engagement with the connecting block, the stability problem during the reset process is solved. In the latter half of the process of removing the cover, the inclined surface of the top block will contact the upward-moving connecting block and guide it to continue moving upward to the locked position, forming a temporary mechanical interlock. This suppresses the up-and-down shaking of the entire mechanism that may be caused after the spring is fully released, ensuring a smooth and certain reset process and improving the overall reliability of the equipment. By setting a linkage between the baffle and the fast-pressing structure, the lower pressing block is automatically driven to engage with the inclined surface of the pressure block while the baffle is being installed, thus completing the wiring fixation and achieving synchronized operation. By setting a manually operable mechanical linkage sealing method, the sealing block 1 and sealing block 2 can be actively driven to tightly compress and seal the inside of the sealing block while the cover is installed, effectively preventing dust and moisture. At the same time, the staggered fixing method of the support block and the straight groove ensures the long-term stability of the sealing state. The integrated design significantly improves the protection level and long-term operational reliability of the meter wiring area. Attached Figure Description

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-7 As shown, a smart meter includes a meter body 1. A display screen 2 is provided on the rear top of the meter body 1. A wiring operation slot 10 is provided on the front top of the meter body 1. A pair of wiring components 5 are provided on the left and right sides inside the wiring operation slot 10. The wiring component 5 is composed of a top piece 6 and a bottom piece 7. The bottom piece 7 is fixedly connected to the inside of the wiring operation slot 10, and the top piece 6 is fixedly connected to the bottom of the bottom piece 7. Sliding grooves 4 are provided on the top and sides inside the wiring operation slot 10. The meter body 1 is slidably engaged with a cover 3 through the three sliding grooves 4. A quick-pressing structure 20 is provided on the top of each pair of wiring components 5. The fast-pressing structure 20 includes two bottom pressure blocks 15, and a connecting block 16 is fixedly connected between two adjacent bottom pressure blocks 15. Two pressure blocks 17 are fixedly connected symmetrically to the bottom of the connecting block 16, and a lower pressure block 19 is provided on the top of the pressure block 17. In actual operation, firstly, the ends of the neutral and live wires in the circuit are placed inside the two adjacent wiring assemblies 5, specifically between the top plate 6 and the bottom plate 7. Then, the fast-pressure structure 20 is activated, so that the neutral and live wires are quickly connected to the meter body 1. The specific steps are as follows: the cover 3 is slid along the three slide grooves 4, which moves the top block 18 backward, thereby moving the lower pressure block 19 backward. This causes the rear inclined surface of the lower pressure block 19 to press against the front inclined surface of the pressure block 17, forcing the pressure block 17 together with the meter body 1. The connecting block 16 and the two bottom pressure blocks 15 slide vertically down the inclined plane, thereby squeezing the top of the two top plates 6, so that the two top plates 6 squeeze the ends of the neutral wire and the live wire respectively, until the bottom of the pressure block 17 contacts and squeezes the bottom of the lower pressure block 19. At this point, the pressure block 17 will be unable to move upward, so the bottom pressure block 15 will be unable to return to its original position. Thus, the two top plates 6 stably and firmly squeeze the ends of the neutral wire and the live wire, thereby achieving the effect of quickly connecting the neutral wire and the live wire to the meter body 1. When the cover 3 is installed, the top block 18 moves horizontally in sync, thereby driving the fast-pressing structure 20 to complete the wiring operation of the neutral and live wires. Therefore, the installation of the cover 3 and the connection operation are carried out simultaneously.

[0020] In this embodiment, the bottom pressure block 15 is located on top of the top piece 6, and the bottom pressure block 15 is pressed against the top of the top piece 6, and the top piece 6 is an elastic metal sheet.

[0021] In this embodiment, the bottom of two adjacent pressing blocks 19 are fixedly connected to a top block 18, and the top block 18 is fixedly connected to the inner side of the cover 3.

[0022] In this embodiment, a fixing block 8 is fixedly connected to the center of the rear part of the wiring operation slot 10, and a double-opening fixing lock 9 is fixedly connected to the center of the inner side of the cover 3. The locking beam of the double-opening fixing lock 9 passes through the fixing block 8, and the lock hole of the double-opening fixing lock 9 passes through the front part of the cover 3. Before installing the cover 3, first pass the locking beam of the double-opening fixed lock 9 through the fixing block 8, and then align it with the body of the double-opening fixed lock 9. After the cover 3 is installed, the locking beam and the body are connected and fixed. Since the double-opening fixed lock 9 is fixedly connected to the cover 3, after the double-opening fixed lock 9 is locked, it means that the cover 3 is locked. Therefore, a key that matches the double-opening fixed lock 9 is needed to open the double-opening fixed lock 9, that is, to open the cover 3. If the cover 3 is forcibly damaged without a matching key lock, the top block 18 cannot be stably fixed for a long time after the cover 3 is destroyed. Therefore, the fast-pressing structure 20 is damaged and becomes ineffective. At the same time, the only way for the top plate 6 to fix the neutral and live wires is through the fast-pressing structure 20. Therefore, when the cover 3 is forcibly destroyed, the neutral and live wires cannot be connected, thus achieving the anti-theft effect and eliminating electricity theft at its source.

[0023] In this embodiment, the front part of the pressure block 17 is inclined, and the rear part of the lower pressure block 19 is also inclined. The inclined angles of the pressure block 17 and the lower pressure block 19 are complementary, and the bottom of the lower pressure block 19 is in contact with the top of the pressure block 17.

[0024] In this embodiment, a tongue 14 is fixedly connected to the bottom front of the cover 3, and a tongue groove 12 is opened at the bottom front of the meter body 1. The tongue 14 and the tongue groove 12 are adaptively matched.

[0025] In this embodiment, four wire slots 13 are provided on the inner side of the cover 3 through the outer side. The positions of the four wire slots 13 correspond one-to-one with the positions of the four wiring components 5. After the neutral wire and the live wire are connected, they will pass through the wire slots 13.

[0026] In this embodiment, reset blocks 21 are fixedly connected to the opposite sides of two adjacent bottom pressure blocks 15. Four fixing rods 22 are fixedly connected inside the wiring operation groove 10. The fixing rods 22 penetrate through the top of the reset block 21. A spring 24 is fixedly connected inside the wiring operation groove 10 and between the bottom of the reset block 21 and on the outer surface of the fixing rod 22. During the process of pressing down the lower pressure block 19, the lower pressure block 15 moves down, which in turn moves the reset block 21 down synchronously, thereby compressing the spring 24. When the bottom of the lower pressure block 19 contacts the top of the pressure block 17, the rebound force of the spring 24 is applied to the body of the lower pressure block 19 through the pressure block 17, so that the pressure block 17 and the lower pressure block 19 are continuously pressed together, thereby increasing the wiring firmness. At the same time, when the cover 3 is removed, so that the lower pressure block 19 and the pressure block 17 are no longer in contact, the spring 24 rebounds, causing the pressure block 17 to move up and reset, so that the top plate 6 no longer presses the neutral wire and the live wire, thereby allowing the neutral wire and the live wire to be replaced or repaired.

[0027] In this embodiment, the top of the fixed rod 22 is fixedly connected to the limit block 23, the spring 24 is in a compressed state, the bottom of the top block 18 is fixedly connected to the vertical block 25, the front of the vertical block 25 is fixedly connected to the top block 11, the front of the top block 11 is inclined, and the top block 11 is located between the two pressure blocks 17. During the removal of the cover 3, the pressure block 17, no longer restricted at its top, moves upward and resets under the restoring force of the spring 24. At this time, the top block 18 continues to slide outward through the cover 3, thereby causing the vertical block 25 and the top block 11 to slide outward synchronously. This causes the front inclined surface of the top block 11 to press against the rear of the connecting block 16. The connecting block 16 moves vertically upward along the front inclined surface of the top block 11 until the bottom of the connecting block 16 contacts the top of the top block 11. At this point, the connecting block 16 cannot move downward, thus fixing the connecting block 16 in this state. Therefore, the bottom pressure block 15 will not shake up and down due to the spring force of the spring 24.

[0028] In this embodiment, sealing blocks 26 are slidably connected to both sides of the inside of the wiring operation slot 10. A pair of wedge blocks 28 are fixedly connected to the side of the sealing blocks 26. A wedge block 27 is slidably connected to the inside of the wiring operation slot 10 and in front of the wedge blocks 28. A fixing block 29 is fixedly connected to the side of the pair of wedge blocks 27 on the same side. A rotating rod 30 is rotatably connected between the two fixing blocks 29. A stop block 3 is fixedly connected to the outer surface of the rotating rod 30 and in front of the two fixing blocks 29. 1. A pair of front blocks 32 are symmetrically fixedly connected to the front part of the wiring operation slot 10. A straight groove 33 is horizontally opened through the front part of the front block 32 and the rear part. A support block 34 is vertically fixedly connected to the outer surface of the rotating rod 30 and in front of the straight groove 33. A pair of top fixing blocks 35 are symmetrically connected to the top of the wiring operation slot 10. A sealing block 26 is slidably connected to the top of the pair of top fixing blocks 35. The bottom of the sealing block 26 is fixedly connected to the fixing block 29 at the rear. The sealing block 26 is L-shaped. After the baffle 3 is connected to the meter body 1, first rotate the two rotating rods 30 so that the support block 34 is in a horizontal state. At this time, the support block 34 and the straight groove 33 overlap in position. Then, the two rotating rods 30 can be moved backward, thereby driving the wedge blocks 27 on both sides to move backward through the fixed block 29 and the baffle 31. This causes the inclined surface of the wedge block 27 to press against the inclined surface of the wedge block 28, so that the two wedge blocks 28 on both sides move along the inclined surface to one end on each side. This causes the L-shaped sealing block 26 to press against the inner sides of the baffle 3. As the fixed block 29 at the rear moves backward, it will drive the sealing block... The second sealing block 36 slides backward along a pair of top fixed blocks 35, thereby pressing the second sealing block 36 against the inside of the baffle 3 at the top. Thus, the inner side of the baffle 3 is sealed by the sealing blocks 26 and 36. When the rotating rod 30 moves to the rearmost end, the support block 34 will be in a horizontal state behind the front block 32. At this time, the rotating rod 30 is rotated again, causing the support block 34 to rotate to a vertical state. At this time, the support block 34 is misaligned with the straight groove 33, thereby fixing the front and rear positions of the rotating rod 30 and even the wedge block 27, so that the sealing blocks 26 and 36 can continue to seal.

[0029] It should be noted that this invention is a smart meter. In use, firstly, the ends of the neutral and live wires in the circuit are placed inside the two adjacent wiring assemblies 5, specifically between the top plate 6 and the bottom plate 7. Then, the fast-pressure structure 20 is activated, allowing the neutral and live wires to quickly connect to the meter body 1. Specifically, the cover 3 slides along the three grooves 4, causing the top block 18 to move backward, thereby moving the lower pressure block 19 backward. This causes the rear inclined surface of the lower pressure block 19 to press against the front inclined surface of the pressure block 17, forcing... The pressure block 17, together with the connecting block 16 and the two bottom pressure blocks 15, slides vertically down the inclined plane, thereby squeezing the tops of the two top plates 6. This causes the two top plates 6 to squeeze the ends of the neutral wire and the live wire respectively. When the bottom of the pressure block 17 contacts and squeezes the bottom of the lower pressure block 19, the pressure block 17 will be unable to move upward, thus preventing the bottom pressure block 15 from resetting upward. As a result, the two top plates 6 stably and firmly squeeze the ends of the neutral wire and the live wire, thereby achieving the effect of quickly connecting the neutral wire and the live wire to the meter body 1.

[0030] When installing the cover 3, the top block 18 moves horizontally, thereby driving the quick-pressing structure 20 to complete the wiring operation of the neutral and live wires. Therefore, the installation of the cover 3 and the connection operation are carried out simultaneously. Before installing the cover 3, the locking beam of the double-opening fixed lock 9 is first passed through the fixing block 8, and then aligned with the body of the double-opening fixed lock 9. After the cover 3 is installed, the locking beam is fixedly connected to the body. Since the double-opening fixed lock 9 is fixedly connected to the cover 3, the cover 3 is locked after the double-opening fixed lock 9 is locked. Therefore, a key that matches the double-opening fixed lock 9 is needed to open the double-opening fixed lock 9, that is, to open the cover 3.

[0031] If a matching key lock is not available and the cover 3 is forcibly damaged, the top block 18 cannot be stably fixed for an extended period. This causes the quick-pressing structure 20 to fail. Furthermore, the only means of securing the neutral and live wires to the top plate 6 is through the quick-pressing structure 20. Therefore, when the cover 3 is removed, it is impossible to connect the neutral and live wires, thus achieving the anti-theft effect and preventing electricity theft at its source. During the downward pressing of the lower pressure block 19, the lower pressure block 15 moves downward, simultaneously moving the reset block. 21 moves down synchronously, thereby compressing the spring 24. When the bottom of the lower pressure block 19 contacts the top of the pressure block 17, the rebound force of the spring 24 acts on the body of the lower pressure block 19 through the pressure block 17, so that the pressure block 17 and the lower pressure block 19 are continuously squeezed, thereby increasing the wiring firmness. At the same time, when the cover 3 is removed, so that the lower pressure block 19 and the pressure block 17 are no longer in contact, the spring 24 rebounds, so that the pressure block 17 moves up and resets, so that the top plate 6 no longer squeezes the neutral wire and the live wire, thereby allowing the neutral wire and the live wire to be replaced or repaired.

[0032] During the removal of the cover 3, the pressure block 17, no longer restricted at its top, moves upward and resets under the restoring force of the spring 24. At this time, the top block 18 continues to slide outward through the cover 3, thereby causing the vertical block 25 and the top block 11 to slide outward synchronously. This causes the front inclined surface of the top block 11 to press against the rear of the connecting block 16. The connecting block 16 moves vertically upward along the front inclined surface of the top block 11 until the bottom of the connecting block 16 contacts the top of the top block 11. At this point, the connecting block 16 cannot move downward, thus fixing the connecting block 16 in this state. Therefore, the bottom pressure block 15 will not shake up and down due to the spring force of the spring 24.

[0033] After the baffle 3 is connected to the meter body 1, first rotate the two rotating rods 30 so that the support block 34 is in a horizontal state. At this time, the support block 34 and the straight groove 33 overlap in position. Then, the two rotating rods 30 can be moved backward, thereby driving the wedge blocks 27 on both sides to move backward through the fixed block 29 and the baffle 31. This causes the inclined surface of the wedge block 27 to press against the inclined surface of the wedge block 28, so that the two wedge blocks 28 on both sides move along the inclined surface to one end on each side. This causes the L-shaped sealing block 26 to press against the inner sides of the baffle 3. As the fixed block 29 at the rear moves backward, it will drive the sealing block... The second sealing block 36 slides backward along a pair of top fixed blocks 35, thereby pressing the second sealing block 36 against the inside of the baffle 3 at the top. Thus, the inner side of the baffle 3 is sealed by the sealing blocks 26 and 36. When the rotating rod 30 moves to the rearmost end, the support block 34 will be in a horizontal state behind the front block 32. At this time, the rotating rod 30 is rotated again, causing the support block 34 to rotate to a vertical state. At this time, the support block 34 is misaligned with the straight groove 33, thereby fixing the front and rear positions of the rotating rod 30 and even the wedge block 27, so that the sealing blocks 26 and 36 can continue to seal.
