DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When implementing: Figure 1-4As shown, a modular electric energy metering box comprises: a splicing box 1, the inner wall of which is plugged with a heat sink 3, the inner wall of which is slidably connected with a mounting plate 2, and one side end of the heat sink 3 is fixedly connected with an exhaust pump 6; a connecting mechanism 4, which is used for quickly disassembling and installing the mounting plate 2 and is arranged on the inner side of the splicing box 1; a retractable cleaning mechanism 5, which is used for cleaning the exhaust pump 6 and does not protrude when taking it out and is arranged on one side of the heat sink 3; wherein the connecting mechanism 4 comprises a pushing component 401 arranged on one side of the splicing box 1, and a fitting component 402 and a pull-back component 403 are arranged on one side of the pushing component 401, and the splicing device can be used to remove the exhaust pump 6 from the inner side of the splicing box 1. The mounting plate 2 is inspected and disassembled. First, the mounting plate 2 can be disassembled, and then the equipment can be installed on the surface of the mounting plate 2. When the installation is completed, the mounting plate 2 is connected by the fitting component 402 and the pushing component 401, and is continuously fixed by the pull-back component 403. When the equipment on the surface of the mounting plate 2 needs to be repaired, the mounting plate 2 is disassembled by the pushing component 401, and then the equipment is repaired or replaced. At the same time, the retractable cleaning mechanism 5 can clean the inside of the exhaust pump 6, and the retractable cleaning mechanism 5 can be stored at the same time, so that when the mounting plate 2 is disassembled, it will not be blocked. For the staff in this technical field, the exhaust pump 6 is a prior art and will not be described in detail here.

[0024] like Figure 3 and Figure 4As shown, the pushing component 401 includes a plurality of positioning bars 4014 fixedly connected to the inner wall of the splicing box 1, a plurality of sockets 4013 are provided on one side end of the mounting plate 2, and the mounting plate 2 is slidably connected to the surfaces of the plurality of positioning bars 4014 through the plurality of sockets 4013, and a gear 4011 is rotatably connected to one side end of the mounting plate 2, and two racks 4012 are slidably connected to one side end of the mounting plate 2, and the two racks 4012 are meshed with the gear 4011, and a plurality of sockets 4013 are provided, which can fit the height of the splicing box 1 when the heat sink 3 is not installed. When the mounting plate 2 is fixed, the sliding of the mounting plate 2 is guided by the positioning bars 4014, and then the mounting plate 2 is pushed to fit the splicing box 1. The inner wall of the gear 4011 is then rotated, so that the gear 4011 pushes the two racks 4012 away from each other, and the fitting positioning strip 4014 fixes the mounting plate 2. One side end of the mounting plate 2 is fixedly connected with two limiting strips 4016. One side end of the two racks 4012 is provided with limiting grooves 4015. The two limiting strips 4016 are respectively slidably matched with the two limiting grooves 4015. When the rack 4012 is meshed with the gear 4011, the rack 4012 is easily skewed, resulting in loosening of the meshing with the gear 4011. When the rack 4012 moves, the limiting groove 4015 is driven to slide on the surface of the limiting strip 4016, so that the rack 4012 is not easy to be skewed when sliding, and fits well. The assembly 402 is provided with two groups, and each group of fitting assembly 402 includes a clamping groove 4021 opened on the surface of the positioning strip 4014, one side end of the rack 4012 is fixedly connected with a push spring 4022, one side end of the push spring 4022 is fixedly connected with a clamping block 4024, and the clamping block 4024 is fitted with the inner wall of the clamping groove 4021. When the gear 4011 pushes the rack 4012 to move, the rack 4012 drives the push spring 4022 and the clamping block 4024 to be inserted into the clamping groove 4021 for fixing, one side end of the rack 4012 is fixedly connected with a telescopic rod 4023, one end of the telescopic rod 4023 is fixedly connected with the clamping block 4024, and the push spring 4022 is sleeved on the telescopic rod 4023. The circumferential surface of the retracted rod 4023 pushes the clamping block 4024 and the clamping groove 4021 for fixation through the pushing spring 4022. At this time, the pushing spring 4022 is easily elastically deformed and damaged. At this time, the pushing spring 4022 is supported by the telescopic rod 4023, so that the pushing spring 4022 is not easy to elastically deform. The pullback component 403 includes a fixing rod 4031 fixedly connected to one side end of the mounting plate 2, and one side end of the fixing rod 4031 is fixedly connected to a torsion spring 4032. One end of the torsion spring 4032 is fixedly connected to the inner wall of the gear 4011. The torsion spring 4032 can continuously push the gear 4011 for fixation to prevent the pushing component 401 from reversing and causing the fixation to loosen.

[0025] like Figure 1 and Figure 2As shown, the storable cleaning mechanism 5 includes a dust removal net 501 slidably connected to the inner wall of the exhaust pump 6, one side end of the dust removal net 501 is movably hinged with a first hinge rod 502, and one end of the first hinge rod 502 is movably hinged with a second hinge rod 503. The dust removal net 501 can be pulled to move by the first hinge rod 502, and the dust removal net 501 on the inner wall of the exhaust pump 6 is pulled to push out the dust in the exhaust pump 6. A storage groove 504 is provided at one side end of the heat sink 3, and the second hinge rod 503 is slidably connected to the inner wall of the storage groove 504. The second hinge rod 503 can be stored through the storage groove 504, so that there will be no obstruction when the mounting plate 2 is disassembled.

[0026] When the utility model is in use, the mounting plate 2 can be detected and disassembled through the assembly of the device. At this time, by rotating the gear 4011, the gear 4011 pushes the rack 4012 to move, and the rack 4012 pulls the clamping block 4024 away from the clamping groove 4021 to loosen the fixation of the mounting plate 2. At this time, the mounting plate 2 can be disassembled, and then the equipment can be installed on the surface of the mounting plate 2. When the installation is completed, the mounting plate 2 pushes the inner wall of the splicing box 1, and then the gear 4011 is released, so the torsion spring 4032 pushes the gear 4011 to rotate, and the gear 4011 pushes the rack 4012 to approach the positioning strip 4014, and the clamping block 4024 fits with the clamping groove 4021 to fix the mounting plate 2. At this time, the installation is completed, and the retractable cleaning mechanism 5 can clean the inside of the exhaust pump 6, and the retractable cleaning mechanism 5 is stored at the same time, so that there is no obstruction when the mounting plate 2 is disassembled.

[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
