At this time, the door is not closed, and outsiders may accidentally touch the electricity meter box, causing problems with the electricity meter box and affecting the normal use of the electricity meter box. Summary of the invention

[0005] In order to improve the problem that the door of an electric energy meter box cannot be closed automatically, the present application provides an electric energy meter box.

[0006] The present application provides an electric energy meter box, which adopts the following technical solution: An electric energy meter box comprises a box body and a box door, wherein the box door is rotatably connected to the box body, the box body is provided with a locking spring, the locking spring is provided with a locking block, the box door is provided with a connecting rope, and one end of the connecting rope away from the box door is provided on the locking block; when the box door is opened, the locking spring is in a stretched state; when the box door is closed, the locking spring is in a non-stressed state.

[0007] By adopting the above technical solution, the staff opens the box door, and the box door drives the locking block to move through the connecting rope, so that the locking block drives the locking spring to stretch. If the staff does not continue to press the box door, the locking spring can drive the box door to close through the locking block and the connecting rope, thereby avoiding the problem that the staff forgets to close the box door, so that the box door can stably block the opening of the box body, making it difficult for external debris to directly enter the box body, and avoiding the phenomenon that external personnel accidentally touch the power meter box and cause problems with the power meter box.

[0008] Optionally, a placement slot for installing electrical components is provided on the box body, a blocking cloth for blocking the placement slot is slidably connected to the box body, and an observation port for observing the electrical components is provided on the blocking cloth.

[0009] By adopting the above technical solution, a blocking cloth is used to block the placement slot, and the electrical components can be observed through the observation port. When the staff only checks the electricity meter box on a daily basis, the staff will not touch the electrical components in the box, thereby further avoiding the possibility of the staff accidentally touching the electrical components, reducing the possibility of the staff being electrically shocked or problems with the electricity meter box, and increasing the safety performance of the electricity meter box.

[0010] Optionally, a first connecting member and a second connecting member are provided on the box body, the first connecting member is electrically connected to an external power supply, the second connecting member is electrically connected to an electrical component, and a connecting strip for connecting the first connecting member and the second connecting member is provided on the baffle cloth; when the baffle cloth blocks the placement groove, the connecting strip is located between the first connecting member and the second connecting member, and at this time the electrical component and the external power supply are electrically connected to each other.

[0011] By adopting the above technical solution, the placement groove is blocked by the blocking cloth, so that the connecting strip is located between the first connecting piece and the second connecting piece, so that the first connecting piece and the second connecting piece can be connected to each other, thereby realizing that the electrical component and the external power supply can be connected to each other, so that the electrical component can operate normally; when the blocking cloth does not block the placement groove, the connecting strip is not between the first connecting piece and the second connecting piece. At this time, the first connecting piece and the second connecting piece cannot be connected, so that the electric energy meter box cannot be used, reminding the staff that the blocking cloth is not installed in place.

[0012] Optionally, a first magnet is slidably connected to the box body, a groove is provided on the locking block, a second magnet for adsorbing the first magnet is provided in the groove, and a movable part is provided on the second connecting part; when the box door is opened and the second connecting part is not powered on, the second magnet adsorbs the first magnet and is inserted into the groove; when the second connecting part is powered on, the movable part is used to drive the first magnet out of the groove.

[0013] By adopting the above technical solution, when the box door is opened and the first connecting member and the second connecting member are not connected, the connecting rope drives the locking block to move, so that the second magnet can absorb the first magnet and move, so that the first magnet is inserted into the groove, and the first magnet limits the locking block, so that the locking block is not easy to slide on the box body; when the box door is opened and the first connecting member and the second connecting member are connected to each other, the moving member can drive the first magnet to disengage from the groove, so that the first magnet does not limit the locking block, and the locking spring can stably drive the locking block to move; if there is a problem with the connection between the connecting strip, the first connecting member and the second connecting member, it is difficult for the moving member to drive the first magnet to disengage from the groove. At this time, the staff can check whether there is a problem with the connection between the connecting strip, the first connecting member and the second connecting member by observing whether the box door is automatically closed, so that the staff does not need to check the circuit condition again at the back end later, thereby reducing the staff's operating steps.

[0014] Optionally, the moving part includes an electromagnet, which is electrically connected to the second connecting part. When the second connecting part is energized, the electromagnet attracts the first magnet to separate from the groove.

[0015] By adopting the above technical solution, the second connecting member is electrically connected to the electromagnet. When the second connecting member is energized, the second connecting member can absorb the first magnet through the electromagnet, allowing the first magnet to disengage from the groove, so that the locking spring drives the locking block to move.

[0016] Optionally, a limiting block is provided on the blocking cloth, and a limiting groove for inserting the limiting block is opened on the locking block; when the blocking cloth does not block the placement groove, the limiting block can be inserted into the limiting groove.

[0017] By adopting the above technical solution, when the cloth does not block the placement slot, the limit block can be inserted into the limit slot, allowing the limit block to limit the locking block, making it difficult for the locking spring to drive the locking block to move, thereby achieving the limitation of the locking block, so that the staff does not need to fix the box door, so that the staff can repair the electrical components in the box.

[0018] Optionally, a winding rod is rotatably connected to the box body, the cloth is made of a flexible material, the cloth is rotatably connected to the winding rod, the winding rod is provided with a torsion spring, the torsion spring is used to wind up the cloth, and the cloth is provided with a stop structure for limiting the movement of the cloth.

[0019] By adopting the above technical solution, the winding rod is driven to rotate by the torsion spring, and the cloth is rotatably connected to the winding rod. When the staff unlocks the cloth through the stopping structure, the torsion spring can drive the cloth to move, thereby realizing automatic winding of the cloth, so that the staff does not need to move the cloth manually, thereby reducing the staff's operating steps.

[0020] Optionally, the stop structure includes a stop strip and a support rod, the support rod is arranged on the baffle cloth, the stop strip is rotatably connected to the support rod, the stop strip is provided with a stop block, and the box body is provided with a stop groove for inserting the stop block; when the stop block is inserted into the stop groove, the baffle cloth blocks the opening of the placement groove.

[0021] By adopting the above technical solution, the staff presses the stop bar. Since the stop bar is rotatably connected to the support rod, the stop block disengages from the stop groove, so that the stop block does not limit the stop bar, allowing the cloth to be separated from the box body; by inserting the stop block into the stop groove, the stop block limits the box body, allowing the cloth to be fixed on the box body.

[0022] Optionally, a fixing groove for installing the winding rod is opened on the box body, and a fixing plate for blocking the fixing groove is slidably connected to the box body.

[0023] By adopting the above technical solution, when the cloth is rolled up on the winding rod, the staff can slide the fixing plate so that the winding rod can be taken out of the fixing groove to facilitate the replacement of the cloth in the winding rod. Since the cloth is made of flexible material, the cloth can be prevented from being damaged and affecting the normal use of the cloth. When the fixing plate blocks the fixing groove, the fixing plate can limit foreign objects from falling into the fixing groove and affecting the subsequent rotation of the winding rod.

[0024] Optionally, a first tooth block is provided on the locking block, a rotating gear is rotatably connected to the box body, a second tooth block is provided on the fixed plate, and the first tooth block and the second tooth block are both meshed and connected to the rotating gear; when the box door is opened, the locking block drives the fixed plate to move, and the fixed plate does not block the opening of the fixed groove.

[0025] By adopting the above technical solution, when the box door is opened, the locking spring drives the locking block to move, so that the first tooth block in the locking block drives the rotating gear to rotate. Since the second tooth block is engaged with the rotating gear, the rotating gear can drive the fixed plate to move, so that the fixed plate does not block the opening of the fixed groove, so that the staff can take the winding rod out of the fixed groove after rolling up the blocking cloth, and the staff does not need to slide the fixed plate again, so that the staff can disassemble or install the winding rod.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The staff opens the box door, and the box door drives the locking block to move through the connecting rope, so that the locking block drives the locking spring to stretch. If the staff does not continue to press the box door, the locking spring can drive the box door to close through the locking block and the connecting rope, thereby avoiding the problem of the staff forgetting to close the box door, so that the box door can stably block the opening of the box body, making it difficult for external debris to directly enter the box body, and avoiding the phenomenon that external personnel accidentally touch the power meter box and cause problems with the power meter box.

[0027] 2. Block the placement slot with the blocking cloth, so that the connecting strip is located between the first connecting piece and the second connecting piece, so that the first connecting piece and the second connecting piece can be connected to each other, thereby realizing that the electrical component and the external power supply can be connected to each other, so that the electrical component can operate normally; when the blocking cloth does not block the placement slot, the connecting strip is not between the first connecting piece and the second connecting piece.
