Description

Technical Field

[0001] This utility model relates to the field of meter box technology, specifically to a meter box that facilitates the installation of electricity meters. Background Technology

[0002] A meter box is a special device used to install and protect electricity meters. It not only provides physical protection but also facilitates the installation, maintenance, and management of electricity meters.

[0003] In existing residential or commercial office buildings, multiple meters for different users are typically installed side-by-side in the meter boxes. When installing a meter individually, the upper part of the back of the meter is usually hung inside the meter box using hooks. Then, workers connect the meter to the power grid and the user's electrical system to ensure accurate metering of electricity consumption. During the wiring process, due to the limited space inside the meter box, workers frequently need to remove the meter or change its angle for wiring operations. Current technology only allows fixing the meter in one position with screws, which is inconvenient for disassembling, changing position, or rotating the meter during wiring, affecting wiring efficiency.

[0004] Furthermore, existing technology typically uses multiple bolts to fix the electricity meter inside the meter box. For installing electricity meters of different sizes, it is necessary to drill holes in multiple different locations inside the meter box, which is inconvenient for both drilling and meter installation. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model provides an electric meter box that facilitates the installation of electric meters.

[0006] The technical solution of this utility model is as follows:

[0007] An electricity meter box that facilitates the installation of an electricity meter includes an electricity meter box body. The electricity meter box body has an inner mounting plate for installing an electricity meter. The inner mounting plate is provided with at least one set of electricity meter limiting units. The electricity meter limiting unit includes two limiting components and a hook located above the limiting components. The position of the hook is adjustable in the vertical direction.

[0008] Two limiting components are symmetrically arranged along the width direction of the meter box body. Each limiting component includes a first transverse rail arranged along the width direction of the meter box body and a slide block that slides with the first transverse rail. Connecting ear plates are symmetrically arranged on both sides of the bottom of the meter. A limiting support plate that can support the connecting ear plates is provided on one side of the slide block. The limiting support plate is connected to the first transverse rail through a connector. The distance between the two slide blocks is adjustable.

[0009] Each meter has a hook slot on the upper back. The hooks are hung in the hook slots to pre-install the meter, making it easy to install the meter in the meter box for wiring. It also makes it easy to frequently remove the meter for wiring operations. The meter box has a limiting component to support and clamp the bottom sides of the meter. The slide of the limiting component can be adjusted according to the size or width of the meter, so that the connecting lugs on both sides of the meter can be placed in the corresponding limiting support plate. This method is suitable for installing different meters in the meter box. Compared to drilling holes in the meter box, the limiting component is a simpler way to fix the meter.

[0010] The specific structure of the aforementioned limiting support plate is as follows: the limiting support plate includes an L-shaped plate and a wedge block. One side of the L-shaped plate is connected to the slide block, and the wedge block is set inside the L-shaped plate. The wedge block has an inclined clamping surface, which is set close to the front side of the first transverse track. Two wedge blocks of the same limiting component form a clamping member for clamping the bottom of the meter. When the connecting ear plates on both sides of the bottom of the meter are placed on the corresponding L-shaped plate, the bottom sides of the meter are squeezed tightly by adjusting the corresponding two or one slide block, and the slide blocks are fixed on the first transverse track by the connecting member, thereby realizing the installation of the meter.

[0011] The specific structure that enables the two wedge blocks to move relative to each other under the drive of the slide to clamp the meter is such that the thickness of the connecting ear plate is located between the maximum and minimum vertical distance between the inclined clamping surface and the front side.

[0012] The connection structure between the aforementioned connector and the first transverse track is as follows: multiple insertion interfaces are provided on the front side along its length. The multiple insertion interfaces are arranged side by side with a small distance between adjacent insertion interfaces, which facilitates fixing the meter by a fixed slide. The connector includes a plug rod that is elastically connected to one side of the slide. The plug rod is inserted into the insertion interface. An elastic element is sleeved on the plug rod. The elastic element can be a tension spring. One end of the tension spring abuts against the end of the plug rod, and the other end abuts against the side of the slide away from the first transverse track. This allows the plug rod to be pulled outward, the tension spring to be stretched, and the plug rod to be pulled out of the insertion interface, which can adjust the position of the slide on the first transverse track.

[0013] Regarding the specific structure of the first transverse track, a T-shaped groove is provided along its length. The slide block is adapted to the T-shaped groove. The slide block will not detach from the first transverse track when it moves. The insertion interface is located above the T-shaped groove, which makes it convenient for staff to adjust the connector on the relatively wide front side of the meter.

[0014] The specific structure of the aforementioned limiting component is as follows: the limiting component also includes a second transverse track, which is located above the first transverse track and is arranged parallel to it. The hook is detachably mounted on the second transverse track. The second transverse track has multiple threaded holes along the vertical direction. The hook is connected to the second transverse track by bolts that mate with the threaded holes. The hook can be adaptively adjusted according to the size of the meter, and is suitable for the installation of meters of different heights or sizes.

[0015] The specific structure and installation position of the wedge block are as follows: the wedge block is a right-angled triangle structure, and the two right-angled faces of the wedge block are connected to the two inner faces of the L-shaped plate near the front side, respectively. The width of the wedge block increases from the outside of the L-shaped plate to the side near the slide.

[0016] The beneficial effects of this utility model are as follows:

[0017] When wiring the electricity meter in the meter box, first hang the upper back of the meter on the hook. The meter can be removed or rotated at any time during wiring. After wiring, adjust the final position of the two slides according to the position of the two connecting lugs of the meter so that the connecting lugs can be placed on the corresponding L-shaped plate. Compared with the existing technology, which requires drilling holes in the meter box every time the meter is installed, this utility model eliminates the need to drill multiple holes in the meter box each time, reducing damage to the overall strength of the meter box. It is suitable for the installation of electricity meters of different models or sizes. The meter can be quickly disassembled or moved during wiring, and the operation is simple.

[0018] The two connecting lugs of the same meter are placed behind the L-shaped plate. The plug rod is pulled outward. By adjusting one or two slides, the wedge blocks on the L-shaped plate can be moved closer to the meter. Then, the meter is squeezed by the inclined clamping surface of the two wedge blocks, and the plug rod is reset and inserted into the corresponding plug interface, so as to realize the quick installation of the meter.

[0019] The second horizontal track has multiple threaded holes along the vertical direction. The hook is connected to the second horizontal track by bolts that mate with the threaded holes, so that the hook can be adjusted according to the size of the meter, making it suitable for the installation of meters of different heights or sizes.

Detailed Implementation

[0031] See Figure 1 , Figure 2 and Figure 3 As shown, a meter box for easy meter installation includes a meter box body 1. The meter box body 1 has an inner mounting plate 101 for installing meters 7. In this embodiment, the inner mounting plate 101 is provided with three sets of meter 7 limiting units. The three sets of meter 7 limiting units are arranged side by side along the width direction of the meter box body 1, which is a horizontal direction. The number of meter 7 limiting units is selected according to the actual number of meters 7 installed. Each meter 7 limiting unit includes two limiting components and a hook 11 located above the limiting components. The position of the hook 11 is adjustable in the vertical direction. The upper part of the back of each meter 7 is provided with a hook groove, which is the prior art. The hook 11 is hung in the hook groove to pre-install the meter 7, which facilitates the installation of the meter 7 in the meter box for wiring and also facilitates the frequent removal of the meter 7 for wiring operations.

[0032] Two limiting components are symmetrically arranged along the width direction of the meter box body 1. The limiting components include a first transverse rail 2 arranged along the width direction of the meter box body 1 and a slide block 4 that slides with the first transverse rail 2. Connecting ear plates 701 are symmetrically arranged on both sides of the bottom of the meter 7. A limiting support plate that can support the connecting ear plate 701 is provided on the outer side of the slide block 4. The limiting support plate is connected to the first transverse rail 2 through a connector. The distance between the two slide blocks 4 is adjustable.

[0033] See Figure 5 , Figure 6 and Figure 7 As shown, the first transverse track 2 has a T-shaped groove 203 along its length. One end of the slide block 4 is provided with a slide bar 401, which is adapted to the T-shaped groove 203. The slide block 4 will not detach from the first transverse track 2 when it moves. The insertion interface 202 is located above the T-shaped groove 203, which makes it convenient for the staff to adjust the connector in front of the relatively wide meter 7.

[0034] In the above structure, the meter box is equipped with limiting components for supporting and clamping the bottom sides of the meter 7. The slide 4 of the limiting components can be adjusted according to the size or width of the meter 7, so that the connecting ear plates 701 on both sides of the meter 7 can be placed in the corresponding limiting support plates. This is suitable for the installation of different meters 7 in the meter box. Compared with the existing technology that requires drilling holes in different positions in the meter box to install the meter 7, the method of fixing the meter 7 by the limiting components in this utility model is simpler, will not damage the overall structure of the meter box, and can be repeatedly disassembled and installed with different types of meters 7 without causing irreversible damage to the meter box.

[0035] See Figure 3 , Figure 4 and Figure 8 As shown, the specific structure of the limiting support plate is as follows: the limiting support plate includes an L-shaped plate 5 and a wedge block 6. One side of the L-shaped plate 5 is connected to the slide block 4. The wedge block 6 is set inside the L-shaped plate 5 and has an inclined clamping surface 601. The inclined clamping surface 601 is set close to the front side 201 of the first transverse track 2. The inclined clamping surface 601 contacts the connecting ear plate 701 of the meter 7. The two wedge blocks 6 of the same limiting component form a clamping member for clamping the bottom of the meter 7. When the connecting ear plates 701 on both sides of the bottom of the meter 7 are placed on the corresponding L-shaped plate 5, by adjusting the corresponding two or one of the slide blocks 4, the bottom sides of the meter 7 are squeezed tightly by the wedge block 6, and the slide blocks 4 are fixed on the first transverse track 2 by the connecting member, thereby realizing the installation of the meter 7. The specific structure and installation position of the wedge block 6 are as follows: the wedge block 6 is a right-angled triangle structure. The two right-angled surfaces of the wedge block 6 are connected to the two inner surfaces of the L-shaped plate 5 near the front side 201, respectively. The width of the wedge block 6 increases from the outside of the L-shaped plate 5 to the side near the slide block 4.

[0036] The two wedge blocks 6 move relative to each other under the drive of the slide block 4 to clamp the meter 7. The specific structure is that the thickness of the connecting ear plate 701 is between the maximum and minimum vertical distance between the inclined clamping surface 601 and the front side surface 201.

[0037] See Figure 2 and Figure 4 As shown, the connection structure between the above-mentioned connector and the first transverse track 2 is as follows: the front side 201 has multiple insertion ports 202 along its length. The multiple insertion ports 202 are arranged side by side, and the distance between two adjacent insertion ports 202 is small, which facilitates fixing the meter 7 by fixing the slide 4. The connector includes a plug rod 8 that is elastically connected to one side of the slide 4. The plug rod 8 is inserted into the insertion port 202. An elastic element 9 is sleeved on the plug rod 8. The elastic element 9 can be a tension spring. One end of the tension spring abuts against the end of the plug rod 8, and the other end abuts against the side of the slide 4 away from the first transverse track 2. This realizes that when the plug rod 8 is pulled outward, the tension spring is stretched, and the plug rod 8 is pulled out of the insertion port 202. The position of the slide 4 on the first transverse track 2 can be adjusted. After the position is adjusted, the plug rod 8 is released, and under the action of the tension spring, it is reinserted into the insertion port 202 to fix the slide 4.

[0038] See Figure 3 , Figure 5 and Figure 7 As shown, the specific structure of the limiting component is as follows: the limiting component also includes a second transverse track 3, which is located above the first transverse track 2 and is arranged parallel to it. The hook 11 is detachably mounted on the second transverse track 3. The second transverse track 3 is provided with multiple threaded holes 301 along the vertical direction. The hook 11 is connected to the second transverse track 3 by bolts 10 that cooperate with the threaded holes 301. The hook 11 can be adaptively adjusted according to the size of the meter 7, and is suitable for the installation of meters 7 of different heights or sizes.
