[0026] As Figures 1 - 3 shown, in one embodiment, a structure of a lead seal door 3 includes a housing 1, a lead seal door base 2 and a lead seal door 3. A first card hole 11 is provided on the upper surface of the housing 1. A through hole 223 is provided at a position corresponding to the first card hole 11 on the lead seal door base 2. A second card hole 31 is provided at a position corresponding to the through hole 223 on the lead seal door 3. Both ends of the through hole 223 communicate with two side surfaces of the lead seal door base 2 respectively. A limiting member 224 is provided in the through hole 223. One end of the limiting member 224 is connected to the inner wall of the through hole 223. A clamping member 225 is provided at the other end of the limiting member 224. One side of the clamping member 225 close to the first card hole 11 extends out of the through hole 223 to form a first clamping member (not marked in the figure), and the first clamping member is clamped with the first card hole 11. One side of the clamping member 225 close to the second card hole 31 extends out of the through hole 223 to form a second clamping member 2251, and the second clamping member 2251 is clamped with the second card hole 31.

[0027] Specifically, in the prior art, the lead seal door 3 and the lead seal door base 2 adopt a rotating shaft assembly structure, with relatively high costs; the lead seal door base 2 and the housing 1 adopt an ultrasonic welding process, with a relatively complex process. In this application, a limiting member 224 is provided on the lead seal door base 2, and a clamping member 225 is provided at the movable end of the limiting member 224. On both sides of the limiting member 224, a first clamping member and a second clamping member 2251 extend along the plane direction of the vertical through hole 223. The first clamping member is clamped with the first clamping hole 11, and the second clamping member 2251 is clamped with the second clamping hole 31. The clamping method between the first clamping member and the first clamping hole 11 is irreversible, and the clamping method between the second clamping member 2251 and the second clamping hole 31 is also irreversible, thus avoiding the situation where the intelligent electric meter and the terminal product are artificially opened without being detected, and improving the safety performance of the structure of the lead seal door 3. The lead seal door 3 of this application adopts an irreversible clamping structure, with low costs, a simple process, convenient installation, and improved production efficiency.

[0028] As Figure 2 shown, in one embodiment, it further includes a connecting member 12. The connecting member 12 is provided on the upper surface of the housing 1. The connecting member 12 includes two symmetrically arranged first guide grooves 121 and a limiting groove 122. One end of the two first guide grooves 121 forms an open end, and the other end of the two first guide grooves 121 is connected to the limiting groove 122.

[0029] The setting of the first guide groove 121 facilitates the sliding of the lead seal door base 2 in the first guide groove 121. The setting of the limiting groove 122 can limit the continuous movement of the lead seal door base 2, facilitating the fixation of the lead seal door base 2 and the housing 1.

[0030] As Figure 2 shown, in one embodiment, the lead seal door base 2 includes a lower base (not marked in the figure). A first slider 211 is provided on the outer periphery of the lower base corresponding to the position of the first guide groove 121, and a limiting block 212 is provided on the outer periphery of the lower base corresponding to the position of the limiting groove 122. When the first slider 211 slides from the open end along the first guide groove 121 to the limiting groove 122, the limiting block 212 abuts against the limiting groove 122.

[0031] Specifically, the housing 1 and the lead seal door base 2 of this application are slidably connected through the first slider 211 and the first guide groove 121, thus facilitating the connection of one end of the lead seal door base 2 with the connecting member 12. When the first slider 211 slides from the open end along the first guide groove 121 to the limiting groove 122, the limiting block 212 abuts against the limiting groove 122, thereby restricting the continuous movement of the lead seal door base 2. At this time, the limiting member 224 is clamped with the clamping hole, thus avoiding the situation where the intelligent electric meter and the terminal product are artificially opened without being detected, and improving the safety performance of the structure of the lead seal door 3. The structure of the lead seal door 3 of this application is convenient to install and has high production efficiency.

[0032] As Figure 2As shown, in one embodiment, the seal door base 2 includes an upper base 22, and the upper base 22 and the lower base are stacked. When the first slider 211 slides from the open end along the first guide groove 121 to the limit groove 122, in the direction perpendicular to the upper surface of the housing 1, the projection of the upper base 22 completely coincides with the connecting member 12.

[0033] The upper base 22 completely covers the upper surface of the connecting member 12, providing a sealing effect for the connecting member 12.

[0034] As Figure 2 shown, in one embodiment, the upper base 22 is provided with a first groove 221 and a second groove 222. The first groove 221 communicates with the second groove 222. A through hole 223 is provided in the first groove 221, and second guide grooves 2221 are provided on the side walls of the second groove 222.

[0035] The communication between the first groove 221 and the second groove 222 facilitates the fixing of the seal door base 2 to the seal door 3.

[0036] As Figure 3 shown, in one embodiment, the seal door 3 includes a sliding member 32. A second slider 321 protrudes outward from the side wall of the second end of the sliding member 32. The second slider 321 is slidably connected to the second guide groove 2221. When the second slider 321 slides along the second guide groove 2221 from the end close to the first groove 221 to the end away from the first groove 221, the outer wall of the first end of the sliding member 32 fits against the inner wall of the second groove 222.

[0037] Specifically, the end where the upper surface of the sliding member 32 is located is the first end. The width of the upper surface of the sliding member 32 is the same as the distance between the two relatively arranged second grooves 222, and the height of the sliding member 32 is the same as the height of the second groove 222. When the second slider 321 slides along the second guide groove 2221 from the end close to the first groove 221 to the end away from the first groove 221, the outer wall of the first end of the sliding member 32 fits against the inner wall of the second groove 222 and slides along the second guide groove 2221 from the end close to the first groove 221 to the end away from the first groove 221. The outer wall of the first end of the sliding member 32 finally completely fits against the inner wall of the second groove 222, thereby sealing the second groove 222 through the first end of the sliding member 32.

[0038] As Figure 3 shown, in one embodiment, the seal door 3 includes a fixing member 322. When the second slider 321 slides from the end close to the first groove 221 to the end away from the first groove 221 along the second guide groove 2221, the fixing member 322 is located in the first groove 221. In the direction perpendicular to the plane of the first groove 221, the limiting member 224 is located within the projection area of the fixing member 322.

[0039] The limiting member 224 is completely blocked by the fixing member 322 to prevent artificial damage to the limiting member 224, thereby separating the lead seal door base 2 from the housing 1 and improving the safety performance of the lead seal door 3 structure.

[0040] Such as Figure 1 and Figure 4 As shown, in one embodiment, it further includes a first lead seal threading hole 3221 and a second lead seal threading hole 226. The fixing member 322 is provided with the first lead seal threading hole 3221, and the second lead seal threading holes 226 are provided on both side walls of the first groove 221. When the second slider 321 slides from the first end to the second end of the second guide groove 2221, the first lead seal threading hole 3221 and the two second lead seal threading holes 226 are located on the same straight line.

[0041] Specifically, the first lead seal threading hole 3221 and the second lead seal threading holes 226 on both sides of the first lead seal threading hole 3221 can be connected through the connecting member 12, thereby fixedly connecting the lead seal door 3 and the lead seal door base 2.

[0042] Furthermore, the connecting member 12 includes connection structures such as a buckle.

[0043] Such as Figure 1 As shown, in one embodiment, it further includes a magnetic attracting steel sheet 4. The magnetic attracting steel sheet 4 is arranged at one end of the connecting member 12 close to the limiting groove 122, and the magnetic attracting steel sheet 4 does not contact the first card hole 11.

[0044] Specifically, by placing the magnetic attracting steel sheet 4 in the connecting member 12, the magnetic attracting steel sheet 4 can help detect the infrared structure inside the housing 1.

[0045] Such as Figure 1 As shown, in one embodiment, the magnetic attracting steel sheet 4 is provided with a first visual hole 41, and the second groove 222 is provided with a second visual hole 2222. When the lead seal door base 2 is slidably connected to the connecting member 12, the first visual hole 41 coincides with the second visual hole 2222.

[0046] When it is necessary to detect the power consumption situation inside the electricity meter box, the lead seal door 3 is separated from the lead seal door base 2, and then other equipment detects the infrared data inside the housing 1 through the first visual hole 41 and the second visual hole 2222.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
