Description

Technical Field

[0001] The utility model relates to the technical field of meter boxes, in particular to an improved return-force door meter box. Background Art

[0002] A meter box is a device box used to measure and record the use of electrical energy. It is usually installed in a power system to monitor and record electrical parameters such as current, voltage, and power in order to measure and bill electricity consumption.

[0003] In the process of long-term use, many outdoor meter boxes have the problem that the staff forget to close the meter boxes, resulting in theft of electricity and foreign objects entering the meter boxes. Generally, the meter boxes are locked by the operating head of the inner triangle. The unlocking device is inconvenient to carry and may be lost. In addition, non-grid staff can easily open the meter boxes with other tools to steal electricity and other illegal behaviors, which seriously affects the healthy operation of the power grid. At the same time, the meter box door now needs the operator to close it with force. Long-term forceful door closing can easily cause the door to deform and damage the meter box. Based on these problems, Chinese patent CN111007294A discloses a back-force door meter box, which is provided with a back-force spring between the box body and the box door so that there is a rebound force between the box door and the box body, so that the box door can be moved closer to the box body under the action of the rebound force and the box door can be automatically closed, effectively solving the problem of forgetting to close the box door and the operator closing the door with force, effectively reducing the situation of forgetting to close the door and damage, and improving the service life.

[0004] A rebound spring is arranged between the box body and the box door in the meter box. Under the action of the rebound force, the box door will slowly move closer to the box body. Therefore, when the staff operates the electronic components in the meter box, the constantly closing box door will cause a lot of inconvenience to the staff. At the same time, the staff's constant blocking of the box door will also cause damage to the rebound structure between the box body and the box door, thereby affecting the service life of the rebound door.

[0009] A back plate is fixedly connected to the rear end of the inner wall of the box, dustproof ventilation nets are passed through both ends of the back plate, and a support plate is fixedly connected to the front end of the back plate.

[0010] As a further description of the above technical solution:

[0011] Side plates are welded to both ends of the top of the bottom plate, and slide groove frames are passed through the opposite sides of the side plates, and gear bars are fixedly connected to the inner walls of the slide groove frames.

[0012] As a further description of the above technical solution:

[0013] The front ends of both sides of the inner wall of the box are fixedly connected to the frame, the bottom and top of the inner wall of the frame are rotatably connected to the shaft, the opposite surfaces of the shaft are fixedly connected to the gear body, and the gear protrusions on the outer wall of the gear body are meshed with the tooth grooves of the gear bar.

[0014] As a further description of the above technical solution:

[0015] The opposite surfaces of the side panels are fixedly connected with sliding rails, the inner walls of the sliding rails are slidably connected with placement plates, the bottom plate is penetrated by a shell, a spring rod is welded at the center of the front end of the support plate, a return spring is sleeved on the outer wall of the spring rod, the outer wall of the return spring is sleeved on the inner wall of the shell, the front ends of the outer walls on both sides of the box body are fixedly connected with hinges, and the movable end of the hinge is rotatably connected to the other side of the rear end of the box door.

[0016] As a further description of the above technical solution:

[0017] A tempered glass plate is passed through the box door, a mounting plate is fixedly connected to the top of the box door, and a locking hook is fixedly connected to the rear end of the mounting plate.

[0018] As a further description of the above technical solution:

[0019] A card slot is provided at one end of the top of the power-on module, a Bluetooth connector is fixedly connected to the other end of the top of the power-on module, and lock hole blocks are fixedly connected to both sides of the front end of the power-on module, and the inner walls of the lock hole blocks are clamped with the outer walls of the lock hooks.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] (1) By setting a first shaft block, a second shaft block, a shaft rod and a connecting rod structure, the bottom plate and the box door can be connected together. When the box door is opened, this structure can drag the bottom plate outward. When the bottom plate slides into the box body, this structure can drag the box door inward, thereby closing the box door. When the power module is turned on, the electric energy will be transmitted to the power electromagnetic block through the power line. At this time, the power electromagnetic block will be magnetic. When the box door is opened, the magnetic block body will approach the power module. At this time, the magnetic block body will be tightly attracted to the magnetic power electromagnetic block, and then the box door cannot be closed. This not only brings a lot of convenience to the staff, but also reduces the damage to the box door's return force structure, thereby further improving the service life of the return force door.

[0022] (2) When the bottom plate is pulled out of the box, the return spring will be squeezed and deformed by the front end of the spring rod, and a rebound force will be formed on the bottom plate. This force can drag the bottom plate back into the box. When the staff pulls out the magnetic card that meets the identity from the card slot or moves the mobile phone connected to Bluetooth away from the box, the power module will automatically cut off the power. At this time, the electromagnetic block will lose its magnetism. As the bottom plate is pulled back into the box, the box door will also close. When the lock hook is inserted into the lock hole block, the entire box door will be locked. By setting a simple connection method between the placement plate and the slide rail, the disassembly and assembly steps of the placement plate are made more convenient and quick. When the bottom plate and side plate are pulled out of the box, the instrument placed on the placement plate is also pulled out of the box. At this time, the bright external environment makes the surface of the instrument and the connected equipment clearer, and also makes it more convenient and quick for the staff to repair, record and replace the instrument.
