[0020] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0022] In this embodiment, the protective device protects the box door 2 and the meter box body 1 through the buffer plate 5 after the box door 2 is closed. When the box door 2 is hit, the impact force will act on the buffer plate 5, wherein the buffer plate 5 is connected to the buffer mechanism 3. The buffer mechanism 3 buffers the buffer plate 5, which can effectively reduce the impact of the external impact force on the meter box body 1 and the box door 2, and plays a protective role for the meter box body 1 and the box door 2, thereby avoiding the box door 2 from being deformed and unable to open due to external impact. In addition, symmetrically distributed sealing gaskets 7 are provided inside the meter box body 1. The sealing gaskets 7 are squeezed by the squeezing mechanism 4 during the closing process of the box door 2, so that the sealing gaskets 7 are tightly fitted with the bottom and top of the box door 2, effectively improving the sealing performance between the box door 2 and the meter box body 1, and can effectively prevent rainwater caused by weather from penetrating into the meter box body 1 to damage electronic devices such as the electric energy meter inside the meter box body 1, thereby improving the protective performance of the electric energy meter metering box.

[0023] See also Figure 2 The buffer mechanism 3 includes a baffle 33 arranged on the inner side of the box door 2, and the baffle 33 is fixedly connected with a plurality of slide bars 31, which penetrate the box door 2 and are fixedly connected to the buffer plate 5, and the outside of the slide bars 31 is provided with a first elastic component 32, and the two ends of the first elastic component 32 are respectively fixedly connected to the box door 2 and the baffle 33; When the box door 2 is hit, the impact force will first act on the surface of the buffer plate 5. The buffer plate 5 is subjected to pressure and drives the baffle 33 to move through the sliding rod 31. The baffle 33 moves and pulls the first elastic component 32, so that the first elastic component 32 is in a stretched state. The first elastic component 32 buffers the baffle 33, and then plays a buffering role on the buffer plate 5, effectively reducing the impact of external impact force on the metering box body 1 and the box door 2, and avoiding the phenomenon that the box door 2 is deformed and cannot be opened due to external impact. The first elastic component 32 can be a spring.

[0024] See also Figure 2 A stabilizing component is provided between the box door 2 and the metering box body 1. When the pressure on the buffer plate 5 reaches a certain level, the stabilizing component is used to perform secondary fixation on the box door 2; When the buffer plate 5 is subjected to a large external impact force, the buffer mechanism 3 reaches the buffer limit. At this time, the stabilizing component will perform secondary fixation on the box door 2, thereby improving the stability between the box door 2 and the meter box body 1, and further improving the protection performance of the electric energy meter meter box.

[0025] See also Figure 3 and Figure 4The stabilizing component includes a groove body arranged on the side wall of the door 2, a pin rod 34 is slidably connected inside the groove body, and the pin rod 34 is connected to the inner wall of the groove body through a second elastic component 35, wherein a pin groove 310 adapted to the pin rod 34 is provided on the inner wall of the door 2, and the pin rod 34 is connected to a fixing component, and the fixing component is used to fix the pin rod 34; When the buffer plate 5 is not subjected to a large impact, under the action of the fixing component, the pin rod 34 is located inside the groove body, which makes it convenient for the staff to close the box door 2. When the buffer plate 5 is subjected to a large impact force, the buffer mechanism 3 reaches the buffering limit. At this time, the fixing component automatically releases the fixation of the pin rod 34, and the pin rod 34 automatically pops out under the action of the second elastic component 35, thereby entering the pin groove 310 on the side wall of the metering box body 1. The cooperation between the pin rod 34 and the pin groove 310 can effectively improve the stability between the box door 2 and the metering box body 1, further improve the impact resistance of the box door 2, and have a strong protection performance for the metering box body 1. The second elastic component 35 can be a spring.

[0026] See also Figure 3 The fixing component includes a slide groove arranged on the inner wall of the box door 2, the slide groove penetrates the groove body, a positioning rod 36 is slidably connected inside the slide groove, a positioning groove is arranged inside the pin rod 34, one end of the positioning rod 36 passes through the positioning groove, and the other end of the positioning rod 36 is fixedly connected to the baffle 33; When the buffer plate 5 is impacted, the buffer plate 5 drives the baffle plate 33 to move through the sliding rod 31, and the baffle plate 33 drives the positioning rod 36 to move. When the baffle plate 33 moves to a certain extent, the positioning rod 36 is simultaneously pulled out from the inside of the positioning groove. The positioning rod 36 is lost, and the pin rod 34 automatically resets, thereby entering the inside of the pin groove 310, thereby playing a secondary fixing role on the box door 2 and the metering box body 1, effectively improving the stability performance between the box door 2 and the metering box body 1.

[0027] See also Figure 4 The pin groove 310 is slidably connected with a push rod 37, and one end of the push rod 37 away from the box door 2 passes through the pin groove 310 and is fixedly connected with a push block 39, and the push block 39 is connected to the outer wall of the metering box body 1 through a third elastic component 38; After the pin rod 34 enters the pin groove 310, when the door 2 needs to be opened, the push rod 37 is pushed by the push block 39, and the push rod 37 squeezes the pin rod 34 while moving until the pin rod 34 moves to the outside of the pin groove 310. At this time, the staff can open the door 2, wherein the third elastic component 38 can play a resetting role on the push block 39 and the push rod 37, and the third elastic component 38 can be a spring.

[0028] See also Figure 5, the extrusion mechanism 4 includes a plurality of trapezoidal blocks 41 fixedly connected to the sealing gasket 7, a movable rod 43 is provided inside the metering box body 1, and a plurality of extrusion blocks 42 for extruding the trapezoidal blocks 41 are fixed on the side wall of the movable rod 43, a plurality of guide rods 46 are fixed on the side wall of the sealing gasket 7, the guide rods 46 extend into the metering box body 1 and are slidably connected to the metering box body 1, a fourth elastic component 45 is provided outside the guide rod 46, and the two ends of the fourth elastic component 45 are respectively fixedly connected to the sealing gasket 7 and the metering box body 1, a plurality of movable blocks 49 are fixed on the outer wall of the movable rod 43, and a plurality of movable grooves 48 are provided on the inner wall of the metering box body 1, the movable block 49 is located inside the movable groove 48 and is slidably connected to the movable groove 48 through the fifth elastic component 47, the movable rod 43 is fixedly connected to a traction rope 44, and the other end of the traction rope 44 is fixedly connected to the rotating rod 6; When the staff closes the box door 2, the box door 2 drives the rotating rod 6 to rotate. When the rotating rod 6 rotates, the traction rope 44 is reeled in. When the traction rope 44 is reeled in, the movable rod 43 is pulled. When the movable rod 43 moves, the inclined surface of the trapezoidal block 41 is squeezed by the squeezing block 42, so that the sealing gasket 7 moves in the direction of the box door 2. When the box door 2 is completely closed, the sealing gasket 7 fits tightly with the box door 2, thereby improving the sealing performance between the box door 2 and the metering box body 1, and can effectively prevent rainwater from penetrating into the metering box body 1 and causing damage to the electric energy meter inside the metering box body 1. The guide rod 46 can play a limiting role on the sealing gasket 7, thereby improving the stability of the sealing gasket 7 when it moves. The fourth elastic component 45 can play a resetting role on the sealing gasket 7. The movable groove 48 can play a limiting role on the movable rod 43 through the movable block 49, thereby improving the stability of the movable rod 43 when it moves. The fifth elastic component 47 plays a resetting role on the movable rod 43. Both the fourth elastic component 45 and the fifth elastic component 47 can be springs.

[0029] Working principle: after the box door 2 is closed, the protective device protects the box door 2 and the metering box body 1 through the buffer plate 5. When the box door 2 is hit, the impact force will act on the buffer plate 5. The buffer plate 5 is subjected to pressure and drives the baffle plate 33 to move through the sliding rod 31. When the baffle plate 33 moves, it pulls the first elastic component 32, so that the first elastic component 32 is in a stretched state. The first elastic component 32 buffers the baffle plate 33, and then plays a buffering role on the buffer plate 5, effectively reducing the impact of external impact force on the metering box body 1 and the box door 2, and avoiding the phenomenon that the box door 2 is deformed and cannot be opened due to external impact. When the baffle plate 33 moves, it also drives the positioning rod 36 to move. When the buffer plate 5 is subjected to a large impact force, the first elastic component 32 reaches the buffering limit, and the positioning rod 36 is simultaneously withdrawn from the inside of the positioning groove, losing The positioning rod 36 is limited, and the pin rod 34 is automatically reset, thereby entering the pin groove 310, thereby playing a secondary fixing role for the box door 2 and the meter box body 1, effectively improving the stability between the box door 2 and the meter box body 1. In addition, when the staff closes the box door 2, the box door 2 drives the rotating rod 6 to rotate, and the rotating rod 6 rotates while the traction rope 44 is reeled in, and the traction rope 44 is reeled in while the movable rod 43 is pulled, and the movable rod 43 moves while the inclined surface of the trapezoidal block 41 is squeezed through the extrusion block 42, so that the sealing gasket 7 moves toward the direction of the box door 2. When the box door 2 is completely closed, the sealing gasket 7 fits tightly with the box door 2, thereby improving the sealing performance between the box door 2 and the meter box body 1, and can effectively prevent rainwater from seeping into the meter box body 1 and causing damage to the electric energy meter inside the meter box body 1.
