Description

Technical Field

[0001] The utility model relates to the technical field of electric meter boxes, in particular to an electric meter box for preventing electricity theft. Background Art

[0002] An electric energy meter, also known as a watt-hour meter, fire meter, or kilowatt-hour meter, is an instrument used to measure various electrical quantities. Enclosing the meter in a meter box provides protection. Existing meter boxes lack alarms when illegally opened, making it prone to electricity theft and resulting in power loss. To address this issue, we propose a meter box designed to prevent theft.

[0003] For example, the patent with announcement number CN214041494U discloses an anti-electricity theft meter box, including a box body, a box door hinged on the box body, a transparent glass fixedly connected to the box door, an insulating shell fixedly connected to the box body, a second conductive sheet connected to the insulating shell through a sliding mechanism, a spring fixedly connected to the second conductive sheet, the lower end of the spring fixedly connected to the box body, a first conductive sheet fixedly connected to the upper end of the insulating shell, a through hole provided in the middle of the first conductive sheet, an insulating rope fixedly connected to the second conductive sheet, the insulating rope passing through the through hole and fixedly connected to the box door, a battery and an alarm fixedly connected to the box body, the alarm being connected to the battery and the first conductive sheet through a wire, and the second conductive sheet being connected to the battery through a wire.

[0004] Through the above configuration, the utility model described in the prior art has the characteristic of preventing electricity theft. However, the electricity meter box of the prior art solution has the following defects during operation:

[0005] When the above device is in use, when the cabinet door is opened, the second conductive piece is pulled by the insulating rope as the cabinet door rotates. When the cabinet door is fully opened, the first conductive piece and the second conductive piece will come into contact, thereby triggering the alarm. The electricity thief can then open the cabinet door a little, cut the insulating rope, and then open the cabinet door completely. In this case, the device will not sound an alarm, and thus cannot play a role in preventing electricity theft. Utility Model Content

[0006] The utility model aims to provide an anti-electricity-theft electric meter box, which is mainly used to solve the technical problem that the prior art has a poor anti-electricity-theft effect.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] The cam is fixedly connected to the inner wall of the meter box, and a rectangular block is provided on the side wall of the rectangular block. A second conductive block is fixedly connected to the top of the inner wall of the rectangular slot, and a first spring is fixedly connected to the bottom of the inner wall of the rectangular slot. The top of the first spring is fixedly connected to the first conductive block, and the first conductive block is slidably connected to the inner wall of the rectangular slot. The side wall of the rectangular block passes through and is slidably connected to a limiting component. The inner wall of the meter box is rotatably connected to a screw rod, and the end of the screw rod is fixedly connected to a driven bevel gear. The outer wall of the screw rod is threadedly connected to a slider. The inner wall of the meter box is fixedly connected to a fixed plate at the screw rod, and the slider is slidably connected to the side wall of the fixed plate. The end of the slider is fixedly connected to a telescopic component, and the lower side wall of the meter box is rotatably connected to a driving component.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working principle: When this device is in use, when someone wants to steal electricity, the protective door will drive the driving component to work during the rotation process, and the driving component will drive the driven bevel gear to rotate. During the rotation of the driven bevel gear, it will drive the screw to rotate, and then the slider drives the telescopic component to move to the left, and the telescopic component drives the limit component to move to the left, so that the first conductive block is not restricted and moves rapidly upward along the inner wall of the rectangular slide under the action of the compressed first spring, so that the first conductive block contacts the second conductive block, and the alarm starts to sound.

[0011] 2.Beneficial effects:

[0012] The existing technology has a technical problem of preventing electricity theft by setting an insulating rope, a first conductive sheet, and a second conductive sheet. However, the existing technology has a technical problem of poor anti-electricity theft effect. This solution has a technical problem of poor anti-electricity theft effect by setting a driving component. When the protective door is opened, the driving component drives the screw rod to rotate, and then the screw rod drives the telescopic component to move to the left, and then the telescopic component drives the limit component to move to the left, so that the first conductive block is not restricted and moves rapidly upward along the inner wall of the rectangular slide groove under the action of the compressed first spring, so that the first conductive block contacts the second conductive block, and the alarm starts to sound an alarm.

[0013] Preferably, the limiting assembly includes a rod slidably connected to the side wall of the rectangular block, the side wall of the first conductive block is provided with a limiting hole adapted to the end of the rod, the end of the rod away from the limiting hole is fixedly connected to the fixed block, the outer wall of the rod is sleeved with a second spring, one end of the second spring is fixedly connected to the side wall of the fixed block, and the other end of the second spring is fixedly connected to the outer wall of the rectangular block. When the device is in use, the first conductive block is first pushed downward, and then the rod is inserted into the inner part of the limiting hole, and then the protective door is closed. When someone steals electricity, the driving assembly will drive the screw rod to rotate. During the rotation of the screw rod, the slider drives the telescopic assembly to move to the left, thereby causing the end of the telescopic assembly to contact the fixed block, so that the fixed block drives the rod to disengage from the limiting hole. During this process, the second spring is stretched. When the rod is completely out of the limiting hole, the first conductive block will be unrestricted. Under the action of the compressed first spring, the first conductive block will quickly move upward along the inner wall of the rectangular slide groove, thereby causing the first conductive block to contact the second conductive block, and the alarm will start to sound, thereby effectively preventing someone from stealing electricity.

[0014] Preferably: the end of the insertion rod close to the limiting hole is provided with an inclined structure, and the insertion rod and the rectangular block are insulators. When the first conductive block needs to be separated from the second conductive block, it is only necessary to press the first conductive block downward to make the first conductive block slide downward along the inner wall of the rectangular slide groove. During this process, the first spring is compressed. When the bottom of the first conductive block contacts the inclined structure at the end of the insertion rod, the insertion rod will slide outward along the side wall of the rectangular block. During this process, the second spring is stretched. When the limiting hole and the insertion rod coincide with each other, the insertion rod is quickly inserted into the inside of the limiting hole under the action of the stretched second spring, and then the protective door can be closed to prevent anyone from stealing electricity.

[0015] Preferably: the telescopic assembly includes a connecting block fixedly connected to the side wall of the slider, a mounting groove is opened at the end of the connecting block, the inner wall of the mounting groove is slidably connected with the telescopic block, the end of the telescopic block is fixedly connected to the third spring, the other end of the third spring is fixedly connected to the inner wall of the mounting groove, during the rotation of the screw rod, the telescopic block is driven to move to the left by the slider, and the end of the telescopic block conflicts with the end of the fixed block, thereby driving the fixed block and the insertion rod to move outward along the side wall of the rectangular block, so that the first conductive block is not restricted, thereby achieving the purpose of automatic alarm.

[0016] Preferably: the end of the telescopic block close to the insertion rod is provided with a sloped structure. When the alarm needs to be turned off, the first conductive block needs to be separated from the second conductive block. Before pressing down the first conductive block, the telescopic rod is retracted into the inside of the installation slot. Under the action of the compressed second spring, the insertion rod is reset, and the first conductive sheet can be pressed down to insert the insertion rod into the inside of the limit hole.

[0017] Preferably: the driving assembly includes a gear rotatably connected to the lower side wall of the meter box, the top of the gear is fixedly connected to a rotating rod, the outer wall of the rotating rod is fixedly connected to a driving bevel gear, and the driving bevel gear and the driven bevel gear are meshed with each other, the inner wall of the protective door is fixedly connected to an arcuate tooth block, and the arcuate tooth block and the gear are meshed with each other. When the protective door is opened, the protective door will drive the arcuate tooth block to rotate, thereby driving the gear to rotate through the arcuate tooth block, and then driving the driving bevel gear to rotate through the rotating rod, and during the rotation of the driving bevel gear, the driven bevel gear and the screw rod are driven to rotate, thereby achieving the purpose of preventing electricity theft.

[0018] Preferably, the two straight sides of the arc-shaped tooth block form a right angle, so that the arc-shaped tooth block can be retracted into the interior of the meter box when the protective door is closed. BRIEF DESCRIPTION OF THE DRAWINGS

The inner wall of protective door 1 is fixedly connected to an arcuate tooth block 7, and the arcuate tooth block 7 and gear 8 are meshed with each other. When protective door 1 is opened, protective door 1 will drive the arcuate tooth block 7 to rotate, thereby driving gear 8 to rotate through the arcuate tooth block 7, and then driving the driving bevel gear 17 to rotate through the rotating rod 6. During the rotation of the driving bevel gear 17, the driven bevel gear 5 and the screw rod 13 are driven to rotate, thereby effectively preventing people from stealing electricity.

During this process, the second spring 20 is stretched. When the limiting hole 22 coincides with the insertion rod 21, the insertion rod 21 is quickly inserted into the inside of the limiting hole 22 under the action of the stretched second spring 20. Then the protective door 1 can be closed to prevent anyone from stealing electricity. When someone wants to steal electricity, when the protective door 1 is opened, the protective door 1 will drive the arc-shaped tooth block 7 to rotate, thereby driving the gear 8 to rotate through the arc-shaped tooth block 7, and then through The rotating rod 6 drives the active bevel gear 17 to rotate, and during the rotation of the active bevel gear 17, the driven bevel gear 5 and the screw rod 13 are driven to rotate.
