Moreover, different fixing structures are set according to different types of metering devices, which can specifically prevent the metering devices from being jolted and collided during transportation, reducing the risk of equipment damage.
[0018] Second, by setting a length adjustment mechanism, the present utility model can adapt to three-phase watt-hour meters and metering terminals of different lengths. By pressing the sliding button to slide it towards the baffle side, the connecting rod is driven to move towards the baffle side. The connecting rod drives the rotating arm of the non-return device to rotate along the rotating shaft, thereby driving the non-return device latch to disengage from the rack. At this time, the baffle can slide freely for length adjustment. After releasing the sliding button, the sliding button moves away from the baffle side under the support of the second spring, thereby driving the connecting rod to move away from the baffle side. The connecting rod drives the rotating arm of the non-return device to rotate along the rotating shaft, thereby driving the non-return device latch to engage with the rack. Since the tooth orientation on the rack is opposite to the sliding direction of the storage drawer, at this time, the baffle is limited and can only slide in the direction of sliding into the storage drawer.
[0019] Third, by setting a locking mechanism, the present utility model can prevent the metering device storage drawer from sliding out. Pull the drawer handle and press the opening button at the same time. The opening button slides inward, causing the connecting rod to pull the push rod to the left, so that the lock catch disengages from the card slot, and at this time, the drawer can be opened. When the opening button is released, the first spring pulls the push rod to move to the right. At this time, the opening button slides outward and the lock catch inserts into the card slot, and at this time, the drawer cannot be opened. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments
[0036] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part rather than all of the embodiments of the present utility model.
[0037] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. Embodiment 1
[0038] Refer to Figure 1 , a movable turnover box for metering equipment, including a turnover box body 1 and a plurality of universal casters 2 arranged at the bottom of the turnover box body 1 for flexible movement; the turnover box body 1 is a rectangular cabinet body. According to the common types of metering equipment and the weight of the metering equipment stored per unit volume, that is, the weight of the metering equipment stored in one layer of drawers, the order of the storage drawers is set. Inside the turnover box body 1, a mutual inductor storage drawer 11, a single-phase electric energy meter storage drawer 12, a metering terminal storage drawer 13, a three-phase electric energy meter storage drawer 14, and a communication module storage drawer 15 are slidably connected in sequence from bottom to top; since the sizes of various metering equipment are different and the heights of each storage drawer are also different. In this embodiment, the heights of the mutual inductor storage drawer 11, the single-phase electric energy meter storage drawer 12, the metering terminal storage drawer 13, the three-phase electric energy meter storage drawer 14, and the communication module storage drawer 15 are 180, 110, 105, 100, and 80 mm respectively, and the length and width of each storage drawer are 410*360 mm. Specifically, both sides of each storage drawer are provided with sliders, and the turnover box body 1 is provided with a slideway matching the sliders.
[0039] The mutual inductor storage drawer 11 is provided with a plurality of rectangular receiving blocks 111 arranged at equal intervals, and the upper surface of the receiving block 111 is provided with a plurality of receiving grooves 112. Specifically, such as Figure 2As shown, four supporting blocks 111 of the mutual inductor storage drawer 11 form a group to constitute a rectangular installation space for the mutual inductor. This rectangular space is smaller than the cross-sectional size of the mutual inductor. The bottom surface of the mutual inductor contacts the top of the supporting block 111. A rectangular receiving groove 112 is provided at the contact position between the mutual inductor and the top of the supporting block 111. The width and length of the rectangular receiving groove 112 are both less than half of the width and length of the supporting block 111, so as to ensure that there is a gap between the left and right mutual inductors for easy access to the mutual inductors. The supporting blocks 111 in contact with the front, rear, left, and right drawer surfaces only need to be half of the complete supporting block 111, and the supporting blocks 111 at the corners are only one-fourth of the normal-sized supporting block 111. More specifically, in this embodiment, there are a total of 12 supporting blocks 111. Among them, the supporting blocks 111 at the four corners are only one-fourth of the normal-sized supporting block 111, and the supporting blocks 111 in contact with the front, rear, left, and right drawer surfaces only need to be half of the complete supporting block 111. A total of 6 rectangular installation spaces for the mutual inductors are formed between the supporting blocks 111. In order to prevent the front and rear mutual inductors from colliding, a separating strip 113 is provided at the center position on the long side of the adjacent supporting blocks 111. After being filled with mutual inductors, the total weight of the mutual inductor storage drawer 11 is 11.6 kg.
[0040] In the single-phase watt-hour meter storage drawer 12, a number of equally spaced separating lining strips 121 are arranged alternately vertically and horizontally. Specifically, as Figure 3 shown, in the single-phase watt-hour meter storage drawer 12, 3 vertical and 1 horizontal equally spaced intersecting separating lining strips 121 are provided, dividing the single-phase watt-hour meter storage drawer 12 into 6 identical single-phase watt-hour meter storage spaces. After being filled with single-phase watt-hour meters, the total weight of the single-phase watt-hour meter storage drawer 12 is 6.6 kg.
[0041] As Figure 4 and Figure 5 shown, in the three-phase watt-hour meter storage drawer 14, a length adjustment mechanism 141 is provided; the metering terminal storage drawer 13 is the same as the three-phase watt-hour meter storage drawer 14; the metering terminal storage drawer 13 is divided into two metering terminal storage spaces, and the three-phase watt-hour meter storage drawer 14 is also divided into two three-phase watt-hour meter storage spaces. A length adjustment mechanism 141 is provided in each metering terminal storage space and three-phase watt-hour meter storage space to prevent the metering terminals and three-phase watt-hour meters from sliding in the box due to different length specifications. After being filled with metering terminals and three-phase watt-hour meters, the weights of the metering terminal storage drawer 13 and the three-phase watt-hour meter storage drawer 14 are 5.7 kg and 4.5 kg respectively.
[0042] The communication module storage drawer 15 is provided with a number of equally spaced installation grooves. Specifically, as Figure 6 shown, there are three specifications for the installation grooves, which are designed according to the sizes of the three commonly used communication modules. The communication module storage drawer 15 can hold a total of 17 communication modules. After being filled with communication modules, the weight of the communication module storage drawer 15 is 4.5 kg. Embodiment 2
[0043] Please refer to Figure 4 and Figure 5 , a length adjustment mechanism 141 is provided in the three-phase electricity meter storage drawer 14; the metering terminal storage drawer 13 is the same as the three-phase electricity meter storage drawer 14; the metering terminal storage drawer 13 is divided into two metering terminal storage spaces, and the three-phase electricity meter storage drawer 14 is also divided into two three-phase electricity meter storage spaces. A length adjustment mechanism 141 is provided in each metering terminal storage space and three-phase electricity meter storage space. The length adjustment mechanism 141 is arranged on the side where the three-phase electricity meter storage drawer 14 slides out for easy use. As Figures 9 - 14 shown, the length adjustment mechanism 141 includes: a base 1411, two slide rails 1412 fixed to the top of the base 1411, a rack 1413 provided on the side of the slide rail 1412, a baffle 1414 slidably connected to the slide rail 1412, two side plates 1415 fixed to both side surfaces of the baffle 1414, a sliding button 1416 sleeved inside a receiving groove 14151 provided in the middle of the side surface of the side plate 1415, a connecting block 14153 provided at the bottom of the side surface of the side plate 1415, a rotating shaft 14154 fixed to the top of the connecting block 14153, and a reverse stopper 1417 sleeved on the rotating shaft 14154. One end of the reverse stopper 1417 is provided with a block that engages with the rack 1413, and the other end of the reverse stopper 1417 is provided with a rotating arm. A connecting rod 14161 is rotatably connected to the rotating arm. The empty end of the connecting rod 14161 is fixedly connected to the sliding button 1416. A second spring 14152 is provided between the sliding button 1416 and the receiving groove 14151. The tooth orientation on the rack 1413 is opposite to the sliding direction of the three-phase electricity meter storage drawer 14. A limiting platform is provided at the end of the rotating shaft 14154 to prevent the reverse stopper 1417 from coming off. A backing plate 143 is provided around the base 1411, and the backing plate 143 can prevent the fixation of the three-phase electricity meter from being interfered by the presence of the base 1411 and the slide rails 1412.
[0044] Please refer to Figure 14, by pressing the sliding button 1416 to slide it towards the baffle 1414, the connecting rod 14161 is driven to move towards the baffle 1414 side. The connecting rod 14161 drives the rotating arm of the check valve 1417 to rotate along the rotating shaft 14154, so as to drive the latch of the check valve 1417 to disengage from the rack 1413. At this time, the baffle 1414 can slide freely for length adjustment. After releasing the sliding button 1416, the sliding button 1416 moves away from the baffle 1414 side under the support of the second spring 14152, thereby driving the connecting rod 14161 to move away from the baffle 1414 side. The connecting rod 14161 drives the rotating arm of the check valve 1417 to rotate along the rotating shaft 14154, so as to drive the latch of the check valve 1417 to engage with the rack 1413. Since the tooth direction on the rack 1413 is opposite to the sliding-out direction of the three-phase watt-hour meter storage drawer 14, at this time, the baffle 1414 is limited to slide only in the direction of sliding into the three-phase watt-hour meter storage drawer 14. Push the baffle 1414 inward to an appropriate distance to fix and lock the three-phase watt-hour meter. When it needs to be taken out, press the side button and pull the baffle 1414 backward to an appropriate distance, then the watt-hour meter can be taken out. Since there is still a gap between the slide rail 1412 and the base 1411, it is convenient for the operator to take the three-phase watt-hour meter. Since the metering terminal storage drawer 13 is the same as the three-phase watt-hour meter storage drawer 14, the specific structure of the metering terminal storage drawer 13 will not be elaborated here. Embodiment 3
[0045] Please refer to Figure 1 and Figure 8 , drawer handles 4 and identification plates 5 are provided on the transformer storage drawer 11, single-phase watt-hour meter storage drawer 12, metering terminal storage drawer 13, three-phase watt-hour meter storage drawer 14, and communication module storage drawer 15.

[0046] Please refer to Figure 5 and Figure 7, To prevent the storage drawers of the metering equipment from sliding out, locking mechanisms 142 are provided on the mutual inductor storage drawer 11, single-phase watt-hour meter storage drawer 12, metering terminal storage drawer 13, three-phase watt-hour meter storage drawer 14, and communication module storage drawer 15. The locking mechanism 142 includes an opening button 1421 slidably connected to the front wall of the drawer, a connecting rod 1422 with one end hinged to the rear end of the opening button 1421, a push rod 1423 hinged to the control end of the connecting rod 1422, a limiting block 1425 fixed on the side wall of the drawer, and a lock catch 1426 slidably connected to the side wall of the drawer. The limiting block 1425 is sleeved on the push rod 1423, and a first spring 1424 is sleeved between the push rod 1423 and the limiting block 1425. Both ends of the first spring 1424 are connected to the push rod 1423 and the limiting block 1425 respectively. A card slot 16 is provided at the contact position between the turnover box body 1 and the connecting lock catch 1426. The opening button 1421 is arranged directly above the drawer handle 4.
[0047] When it is necessary to open the storage drawer, pull the drawer handle 4 with four fingers and press the opening button 1421 with the thumb at the same time. The opening button 1421 slides inward, causing the connecting rod 1422 to pull the push rod 1423 to the left, so that the lock catch 1426 disengages from the card slot 16, and at this time the drawer can be opened. Then release the drawer handle 4 and the opening button 1421 to take or place the metering equipment. When it is necessary to close the storage drawer, press the opening button 1421 and slide the storage drawer into the interior of the turnover box body 1 at the same time. The pressing process will not be elaborated here. When the storage drawer is in place, release the opening button 1421. At this time, the first spring 1424 pulls the push rod 1423 to move to the right, the opening button 1421 slides outward, and the lock catch 1426 inserts into the card slot 16, and at this time the drawer cannot be opened.
