[0029] Refer to Figures 1-4 , a protection device for an electric energy meter box, including a box body 1, a box door 2 is hinged to the front of the box body 1, an inner cavity 3 is opened inside the box door 2, a fixed airbag 4 is fixedly connected to the inner side wall of the inner cavity 3, one end of the fixed airbag 4 is fixedly connected to a connecting plate 5, one end of the connecting plate 5 is fixedly connected to a first fixing block 6, one end of the first fixing block 6 is rotatably connected to a connecting rod 7, one end of the connecting rod 7 is rotatably connected to a second fixing block 8, one end of the second fixing block 8 is fixedly connected to a buffer plate 9, one end of the buffer plate 9 is fixedly connected to a buffer spring 10, one end of the buffer spring 10 is fixedly connected to a protection plate 11, an elastic sliding sleeve 12 is fixedly arranged at one end of the box door 2, a sliding plate 15 is fixedly installed on the inner side wall of the box body 1, a support plate 16 is slidably connected to the inner side wall of the sliding plate 15 through a slide rail, a first shock-absorbing spring 17 is fixedly connected to the top of the support plate 16, and a placement box 18 is fixedly connected to the top of the first shock-absorbing spring 17.

[0030] Specifically, sliding grooves 13 are formed in the inner walls on both sides of the box door 2. A clamping block 14 is slidably connected to the inner wall of the sliding groove 13, and the inner wall of the clamping block 14 is clamped with the buffer plate 9. This structure effectively fixes and guides the buffer plate 9, making its movement on the inner side wall of the box door 2 more stable and controllable, increasing the stability and uniform stress distribution of the buffer plate 9, thereby enhancing the shock absorption effect of the buffer plate 9. This helps the buffer plate 9 better absorb and disperse the impact force when the box door 2 is subjected to an external impact, protecting the safety of the internal power metering device.

[0031] Specifically, the number of the first shock-absorbing springs 17 is several groups, and several groups of the first shock-absorbing springs 17 are arranged in a rectangular array on the top of the support plate 16. This structure enables uniform support and force distribution for the buffer plate 9, effectively reducing deformation or damage caused by uneven force on the first shock-absorbing springs 17, and ensuring the reliability and stability of the protection device.

[0032] Specifically, threaded rods 19 penetrate and are threadedly connected to the side walls on both sides of the placement box 18. One end of the threaded rod 19 is fixedly connected to a tightening ring 20, and the other end of the threaded rod 19 is fixedly connected to a limiting plate 21. This structure drives the limiting plate 21 to fix the power meter inside the placement box 18 through the cooperation of the tightening ring 20 and the threaded rod 19, making it not prone to loosening or falling off, thereby ensuring the stability and reliability of the protection device. A rubber buffer pad is adhesively bonded to the front surface of the limiting plate 21. This structure can provide additional buffer protection. When the power meter is subjected to an external impact, the rubber buffer pad can absorb part of the impact force, reducing the impact on the internal power metering device and further improving the protection effect of the protection device.

[0033] Specifically, a telescopic rod 22 is fixedly connected to the inner wall of the box body 1, and a second shock-absorbing spring 23 is sleeved outside the telescopic rod 22. This structure enables the placement box 18 to have stronger shock absorption ability. When an external impact acts on the box body 1, the second shock-absorbing spring 23 can transmit and absorb part of the impact energy through the telescopic rod 22, reducing the impact on the internal power metering device and improving the protection effect.

[0034] Specifically, heat dissipation windows 24 are formed in the inner walls on both sides of the box body 1, and a filter screen 25 is fixedly connected to the outside of the heat dissipation windows 24 through bolts. This structure enables the heat dissipation windows 24 to promote air convection and improve the heat dissipation effect. At the same time, the filter screen 25 can protect the inside of the box from intrusion of external sundries, keeping the power metering device clean and operating stably.

[0035] Specifically, one end of the elastic sliding sleeve 12 is fixedly connected to a reinforcing plate 26. This structure can provide additional support under external impact or vibration, enhance the overall structural strength of the protective device, and thus effectively protect the internal power metering device from external influences. One end of the reinforcing plate 26 is fixedly connected to a handle 27, and the surface of the handle 27 is sleeved with an anti-slip rubber sleeve. The anti-slip rubber sleeve can increase the friction of the handle 27, prevent the handle from sliding during transportation, and increase the comfort of use.

[0036] Working principle: When in use, when installing the electricity meter, the operator first opens the box door 2, then pulls out the support plate 16 through the sliding plate 15, and installs the electricity meter inside the placement box 18. According to the size of the electricity meter, manually screw in the tightening rings 20 on both sides of the placement box 18, and drive the limit plate 21 to move under the push of the screw 19, so as to fix the electricity meter. In addition, the first shock-absorbing spring 17 and the second shock-absorbing spring 23 have a good shock-absorbing effect on the placement box 18, effectively protecting the electricity meter. The heat dissipation window 24 can always ensure ventilation in the box body 1, and has a heat dissipation effect on the power protection box. In addition, the filter net 25 can well filter the external dust layer into the interior of the box body 1, effectively protecting the interior of the box body 1. In order to improve the cleanliness of the internal environment, when the box door 2 is impacted, the force will first act on the reinforcing plate 26. The protective plate 11 and the reinforcing plate 26 can increase the strength of the box door 2 and avoid damage to the box door 2 as much as possible. The impact force can be absorbed by multiple buffer springs 10 and the fixed airbag 4, thereby ensuring the anti-impact protection effect of the box door 2. Through the cooperation between the first fixed block 6, the connecting rod 7 and the second fixed block 8, the buffer plate 9 can be limited and buffered, so that through the cooperation between the fixed airbag 4, the connecting plate 5, the first fixed block 6, the connecting rod 7, the second fixed block 8, the buffer plate 9, the buffer spring 10 and the protective plate 11, the inner side of the box door 2 can have a buffering and pressure-resistant effect, thereby achieving the purpose of protecting the box door 2 against impact.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
