Description

Technical Field

[0001] This utility model relates to the field of electricity metering box technology, specifically to an electricity metering box with a safety protection device. Background Technology

[0002] Electricity metering boxes are one of the commonly used components in power systems. They have advantages such as high accuracy, light weight, wide load range, convenient installation, and anti-theft features. They are used for voltage, current, and energy measurement and relay protection. They are suitable for outdoor substations in urban and rural power grids, as well as various transformer substations in industrial enterprises. Since electricity metering boxes are placed outdoors, they are easily affected by various weather conditions. Therefore, an electricity metering box with safety protection devices is needed.

[0003] According to a public notice regarding an electricity metering box with a safety protection device (Notice No.: CN220306781U), the aforementioned application effectively prevents unauthorized personnel from contacting or damaging the locking device by shielding it. Therefore, by providing a shield on the front of the locking device, with the shield slidably mounted on the first and second slide rails of the box door, and by providing a detachable mating part on the rotation trajectory of the mounting part on the shield, the locking device can be detachably connected to the box door without needing to release its locking relationship. Thus, without external force, the projection of the locking device onto the shield falls on the front, preventing unauthorized personnel from directly contacting it and thus avoiding direct force application or damage to open the box.

[0004] However, in actual use, the door of the aforementioned device is connected to the box body, and there is a gap between the door and the box body. In rainy or humid weather, water may seep into the box body, causing the electricity metering box to short-circuit and be damaged. In view of this, we propose an electricity metering box with a safety protection device. Utility Model Content

[0005] The purpose of this utility model is to provide an electricity metering box with a safety protection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electricity metering box with a safety protection device, comprising a box body, a sealing cover rotatably connected to the outer wall of the box body, a locking plate fixedly connected to the outer wall of the sealing cover, a latch fixedly connected to the outer wall of the locking plate, a lock head penetrating the outer wall of the latch, a sealing strip fixedly connected to the outer wall of the sealing cover, an electricity meter fixedly connected to the inner wall of the box body, and a sealing assembly provided inside the box body, the sealing assembly comprising:

[0007] A push plate is slidably connected to the inner wall of the box. A return spring is fixedly connected to the outer wall of the push plate. A rotating rod is rotatably connected to the inner wall of the box. Both ends of the rotating rod are provided with return torsion springs. A baffle is fixedly connected to the end of the rotating rod near the push plate. The baffle contacts the push plate. A sealing plate is fixedly connected to the end of the rotating rod away from the baffle.

[0008] A telescopic locking block is fixedly connected to the outer wall of a sealing plate. A handle is fixedly connected to the outer wall of the sealing cover. A pressure rod is slidably connected through the outer wall of the handle. The end of the pressure rod away from the handle contacts the telescopic locking block. A compression spring is fixedly connected to the outer wall of the pressure rod.

[0009] Preferably, the outer side of the box is provided with a fixing component, the fixing component includes a clamping plate, the clamping plate is rotatably connected to the outer wall of the box, a clamping torsion spring is provided at the connection between the clamping plate and the box, a magnetic sheet is fixedly connected to the outer wall of the clamping plate, a flow guide block is fixedly connected to the outer wall of the clamping plate, and a groove is opened on the outer wall of the sealing strip, the clamping plate engages with the groove.

[0010] Preferably, the inner wall of the housing has a through-hole locking groove, and the outer wall of the housing has a through-hole sliding groove. The sliding groove is connected to the inclined surface of the locking groove. The pressure rod is in contact with the telescopic locking block. When the pressure rod is pressed down, the pressure rod presses down to retract the telescopic locking block, thereby unlocking the sealing cover from the sealing plate.

[0011] Preferably, the outer wall of the box is fixedly connected with a magnetic sheet whose magnetic properties are opposite to those of the magnetic sheet on the card plate. When the card plate rotates, the magnetic sheet on the card plate comes into contact with the magnetic sheet on the box, thus connecting the card plate to the box and causing the card plate to leave the card slot, thereby causing the sealing cover to leave the box.

[0012] Preferably, the guide block is shaped as a right-angled triangle, with its right-angled sides fitting against the sealing strip and the housing respectively, so that the guide block can block the gap between the sealing strip and the housing and guide the water flow out from the sealing cover.

[0013] Preferably, a limiting plate is fixedly connected to the outer wall of the push plate, the limiting plate is fixedly connected to a reset spring, and the end of the reset spring away from the limiting plate is fixedly connected to the inner wall of the box. When the sealing cover drives the sealing strip to rotate and press the push plate, the push plate pushes the baffle to make the sealing plate rotate, blocking the gap between the sealing cover and the box.

[0014] Preferably, a pressure plate is fixedly connected to the end of the pressure rod away from the housing, the pressure plate passes through the handle, and the pressure rod is slidably connected to the handle, so that the handle will only be opened when it is gripped.

[0015] Compared with the prior art, this utility model provides an energy metering box with a safety protection device, which has the following beneficial effects:

[0016] 1. This energy metering box with safety protection device uses a sealing strip to cover the push plate on the box body. The push plate pushes open the baffle, causing the rotating rod to rotate and the sealing plate to rotate, blocking the gap between the sealing cover and the box body. At this time, the sealing cover and the sealing plate are in contact, and the telescopic block engages with the locking groove to prevent water leakage. When it is necessary to open the sealing cover, hold the handle, so that the pressure plate presses the pressure rod and pushes the telescopic block to retract. This allows the sealing cover to be opened only when the handle is pressed, preventing the sealing cover from loosening and releasing the seal.

[0017] 2. The power metering box with safety protection device uses a rotating plate to engage with the slot, and a guide block to block the gap between the sealing strip and the box body, allowing water to flow down from the guide block and preventing water from flowing into the box body.

[0023] like Figures 1-4As shown, this utility model provides a technical solution: an electricity metering box with a safety protection device, including a box body 1, a sealing cover 2 rotatably connected to the outer wall of the box body 1, a locking plate 3 fixedly connected to the outer wall of the sealing cover 2, a latch 4 fixedly connected to the outer wall of the locking plate 3, a lock head 5 penetrating the outer wall of the latch 4, a sealing strip 6 fixedly connected to the outer wall of the sealing cover 2, an electricity meter 7 fixedly connected to the inner wall of the box body 1, and a sealing assembly 8 provided inside the box body 1. The sealing assembly 8 includes a push plate 81, a return spring 82, a baffle 83, a rotating rod 84, a return torsion spring 85, a sealing plate 86, a telescopic block 87, a handle 88, a pressure rod 89, and a compression spring 810.

[0024] In one embodiment of this utility model, a push plate 81 is slidably connected to the inner wall of the housing 1. A return spring 82 is fixedly connected to the outer wall of the push plate 81. A rotating rod 84 is rotatably connected to the inner wall of the housing 1. Both ends of the rotating rod 84 are provided with return torsion springs 85. A baffle 83 is fixedly connected to the end of the rotating rod 84 near the push plate 81. The baffle 83 contacts the push plate 81. A sealing plate 86 is fixedly connected to the end of the rotating rod 84 away from the baffle 83.

[0025] In one embodiment of this utility model, the telescopic block 87 is fixedly connected to the outer wall of the sealing plate 86, the outer wall of the sealing cover 2 is fixedly connected to the handle 88, the outer wall of the handle 88 is slidably connected to the pressure rod 89, the end of the pressure rod 89 away from the handle 88 is in contact with the telescopic block 87, and the outer wall of the pressure rod 89 is fixedly connected to the compression spring 810.

[0026] In one embodiment of this utility model, a fixing component 9 is provided on the outside of the box 1. The fixing component 9 includes a clamping plate 91, which is rotatably connected to the outer wall of the box 1. A clamping torsion spring 92 is provided at the connection between the clamping plate 91 and the box 1. A magnetic sheet 93 is fixedly connected to the outer wall of the clamping plate 91. A flow guide block 94 is fixedly connected to the outer wall of the clamping plate 91. A groove 95 is opened on the outer wall of the sealing strip 6, and the clamping plate 91 is engaged with the groove 95.

[0027] In addition, the inner wall of the housing 1 is provided with a through locking groove, and the outer wall of the housing 1 is provided with a through sliding groove. The sliding groove is connected to the inclined surface of the locking groove. The pressure rod 89 contacts the telescopic locking block 87. When the pressure rod 89 is pressed down, the pressure rod 89 presses down to retract the telescopic locking block 87, thereby unlocking the sealing cover 2 from the sealing plate 86, so that the sealing cover 2 can be opened when the handle 88 is gripped.

[0028] In an embodiment of this utility model, a magnetic sheet 93 with the opposite magnetic properties to the magnetic sheet 93 on the card plate 91 is fixedly connected to the outer wall of the box body 1. When the card plate 91 rotates, the magnetic sheet 93 on the card plate 91 comes into contact with the magnetic sheet 93 on the box body 1, so that the card plate 91 is connected to the box body 1, thereby causing the card plate 91 to leave the card slot 95, and thus causing the sealing cover 2 to leave the box body 1.

[0029] In an embodiment of this utility model, the shape of the guide block 94 is set as a right-angled triangle, and the right-angled sides of the guide block 94 are respectively attached to the sealing strip 6 and the box body 1, so that the guide block 94 can block the gap between the sealing strip 6 and the box body 1, and guide the water flow from the sealing cover 2, so that the water flow is not easy to flow into the box body 1 from the gap between the sealing strip 6 and the box body 1.

[0030] In this embodiment of the utility model, a limiting plate is fixedly connected to the outer wall of the push plate 81, and the limiting plate is fixedly connected to the return spring 82. The end of the return spring 82 away from the limiting plate is fixedly connected to the inner wall of the box 1. When the sealing cover 2 drives the sealing strip 6 to rotate and press the push plate 81, the push plate 81 pushes the baffle 83 to make the sealing plate 86 rotate, blocking the gap between the sealing cover 2 and the box 1. When the sealing strip 6 leaves the push plate 81, the push plate 81 extends out of the box 1 through the return spring 82 for easy use next time.

[0031] In an embodiment of this utility model, a pressure plate is fixedly connected to the end of the pressure rod 89 away from the box body 1. The pressure plate passes through the handle 88, and the pressure rod 89 is slidably connected to the handle 88, so that the handle 88 will only be opened when it is gripped, so that the sealing cover 2 will not be released when the clamping plate 91 is loose, and water will leak into the electricity metering box.

[0032] In this utility model, during use, the sealing cover 2 is rotated to make the sealing strip 6 fit against the box body 1. At this time, the latch 4 passes through the locking plate 3, and the lock head 5 passes through the latch 4, so that the sealing cover 2 covers the opening of the box body 1. The sealing strip 6 covers the push plate 81 on the box body 1, so that the push plate 81 slides on the inner wall of the box body 1, thereby causing the push plate 81 to push open the baffle 83, and causing the rotating rod 84 to rotate, so that the sealing plate 86 rotates to block the gap between the sealing cover 2 and the box body 1. At this time, the sealing cover 2 and the sealing plate 86 are fitted together to prevent water from leaking into the electricity metering box and damaging the electricity metering box. When the sealing plate 86 and the sealing cover 2 are fitted together, the telescopic block 87 engages with the locking groove, so that the sealing cover 2 is fixed on the box body 1. The movable plate 91 engages with the slot 95. The guide block 94 blocks the gap between the sealing strip 6 and the box 1, allowing water to flow down from the guide block 94 and preventing water from flowing into the box 1. When it is necessary to open the electricity metering box, first rotate the plate 91 to attract the magnetic pieces 93, thus keeping the plate 91 away from the slot 95. At this time, hold the handle 88 to press the pressure plate against the pressure rod 89, which in turn pushes the telescopic block 87, causing the telescopic block 87 to retract and the sealing cover 2 to leave the sealing plate 86. The sealing cover 2 can only be opened when the handle 88 is pressed down, preventing the sealing cover 2 from loosening and releasing the seal, allowing water to leak into the box 1 and causing damage to the box 1.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
