Description

Technical Field

[0001] This invention relates to the field of electrical equipment, and more specifically to an electric meter box equipped with a modular and adjustable internal layout structure. Background Technology

[0002] An electricity meter box is a device used to install and protect electricity meters. It is usually installed on the exterior or inside of residential, commercial or industrial buildings, and typically contains electrical components such as electricity meters, circuit breakers, isolating terminals and wiring terminals.

[0003] Currently, when installing an electricity meter in a meter box, the meter must first be placed in the designated location within the box, then secured with screws or other fixing devices, and finally the power cord is connected. During this installation process, for ease of maintenance, the meters are typically installed quite compactly within the meter box. Therefore, when installing meters near the top or bottom, the limited space restricts the installer's hand movement, hindering the tightening of screws with tools. Furthermore, when wiring the top meter, obstructed visibility makes it difficult to clearly see the terminals and markings, increasing the risk of incorrect connections. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a mold processing optimization system based on a rotary punching structure, which can effectively solve the problem in existing technologies where insufficient space obstructs tool use and visibility during meter installation, leading to inconvenience in operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An electric meter box with a modular and adjustable internal layout includes:

[0007] The support part includes a horizontal fixed frame, two of which are evenly fixedly connected vertically. Multiple vertical movable frames are slidably connected to the two horizontal fixed frames from left to right. The vertical movable frames are U-shaped, and three circular positioning holes are evenly and symmetrically opened from top to bottom on the two vertical sections corresponding to the vertical movable frames.

[0008] The connecting part includes an outer connector, which is connected to the meter by a fastener. Three inner connectors are installed on the vertical movable frame, and the inner connectors are detachably connected to the outer connectors.

[0009] The inner connector includes a mounting shell, which consists of a rectangular shell and two mounting tubes that are symmetrically fixed and connected to both sides of the rectangular shell. The mounting shell is slidably connected to the vertical movable frame. The front end of the mounting shell is connected to a clamping component that cooperates with the outer connector. An adjusting component is connected inside the mounting shell.

[0010] Furthermore, the external connector includes a plug plate, which is fixedly connected to the rear side of the meter by external fasteners. Two round rods are symmetrically fixedly connected to the rear end face of the plug plate, and wedges are symmetrically fixedly connected to both ends of the round rods.

[0011] Furthermore, the clamping component includes a folding plate, the rear end face of the vertical section behind the folding plate is connected to the adjusting component, and two clamping modules that cooperate with the round rod are symmetrically connected to the front end face of the vertical section behind the folding plate.

[0012] Furthermore, the clamping module includes an arc-shaped clamping plate, which is an arc and has two symmetrically arranged vertically. The rear ends of the two arc-shaped clamping plates are rotatably connected to the folding plate via short rods. A long plate is fixedly connected to the outer circumference of the arc-shaped clamping plate. The long plate and the folding plate are connected by two symmetrically arranged push springs.

[0013] Furthermore, the adjusting component includes abutments, two of which are symmetrically connected and slidably connected within the mounting housing. Each abutment has a stepped groove extending from front to back, and the two stepped grooves also align when the two abutments are joined together. The front half of the two stepped grooves is oval, and the rear half is circular. The abutments are connected to the mounting housing via a spring. Each abutment is connected to a positioning module that mates with a circular positioning hole. The positioning module and the folding plate are connected together to a locking module. An adjusting module is connected to the front end of the mounting housing.

[0014] Furthermore, the positioning module includes a positioning block, which is cylindrical and slidably connected in the mounting tube. The positioning block can rotate inside the mounting tube. The positioning block is connected to the corresponding abutment block by a second spring, and the positioning block and the second spring can rotate relative to each other. The positioning block has a chamfer that matches the circular positioning hole.

[0015] Furthermore, the locking module includes a slot, a slot is provided through the front and rear of the positioning block, a chamfer is provided at one end of the stepped groove near the abutment block, and a plug rod is fixedly connected to the vertical section in front of the folding plate. The rear end of the plug rod is provided with an inclined surface that matches the chamfer on the slot.

[0016] Furthermore, the adjustment module includes a limiting tube, which is fixedly connected to the front end of the mounting shell. A cylindrical seat is slidably connected inside the limiting tube. A hinge block is rotatably connected to the front end of the cylindrical seat. The hinge block and the folding plate are fixedly connected. A connecting rod is fixedly connected to the rear end of the cylindrical seat. A strip groove that cooperates with the connecting rod is opened through the vertical movable frame in the vertical direction. The connecting rod is slidably connected in the strip groove. A limiting piece that prevents the cylindrical seat from detaching from the mounting shell is fixedly connected to the rear end of the connecting rod.

[0017] Compared with the prior art, the technical solution provided by this invention has the following advantages: When installing the electricity meter on the vertical movable frame, the staff can move the position of the vertical movable frame in the meter box as needed, and also move the position of each internal connecting part on the vertical movable frame as needed, thereby reducing the difficulty of installing the electricity meter at a low or high position. When installing the electricity meter on the internal connecting part, it is only necessary to first fix the external connecting part to the electricity meter, and then fix the two round rods on the external connecting part in the corresponding clamping module. The installation method is relatively simple. After the installation is completed, the vertical movable frame and the external connecting part are moved to the designated position. Then, before locking them through the locking module, the column base is outside the limit tube. Therefore, the folding plate, clamping module, external connecting part and electricity meter can also rotate up and down a certain angle. When wiring, the installer can turn the electricity meter up or down as needed to quickly find the hole position, reduce the wiring difficulty and avoid wiring errors. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] The present invention will be further described below with reference to embodiments.

[0030] Example:

[0031] See Figures 1-8 A meter box with a modular and adjustable internal layout includes:

[0032] Support part 1, the support part 1 includes a horizontal fixed frame 11, two horizontal fixed frames 11 are evenly fixedly connected vertically, and multiple vertical movable frames 12 are slidably connected to the two horizontal fixed frames 11 from left to right. The vertical movable frames 12 are U-shaped, and three circular positioning holes 13 are evenly and symmetrically opened from top to bottom on the two vertical sections corresponding to the vertical movable frames 12.

[0033] The connecting part 2 includes an outer connector 21, which is connected to the meter by fasteners. Three inner connectors 22 are installed on the vertical movable frame 12, and the inner connectors 22 are detachably connected to the outer connectors 21.

[0034] During the initial installation of the electricity meter, all three vertical movable brackets 12 are adjusted to a position close to the center inside the meter box. The inner connecting parts 22 located at the top and bottom are also adjusted to a height that is convenient for operation. Before installing the electricity meter, each electricity meter is first fixedly connected to the outer connecting part 21, and then the outer connecting part 21 is connected to the inner connecting part 22. During the installation process, in order to facilitate the installation, the electricity meters located on the two vertical movable brackets 12 are installed first. After the installation is completed, the two vertical movable brackets 12 are moved to the designated position. After the two sides are installed, the electricity meter is installed on the middle vertical movable bracket 12. Compared with the conventional installation method, this installation method can avoid the situation where the electricity meters are arranged in a compact manner inside the meter box and the space on the left and right sides is too small to facilitate installation.

[0035] After the above installation is completed, slide each meter up and down along each vertical movable frame 12 to adjust it to the designated position. After reaching the designated position, the inner connector 22 can automatically engage with the circular positioning hole 13. At this time, the meter can still rotate up and down a certain angle to facilitate wiring by the installer. After the wiring is completed, press the meter to fix it through the inner connector 22.

[0036] The inner connector 22 includes a mounting shell 221, which consists of a rectangular shell and two mounting tubes that are symmetrically fixed and connected to both sides of the rectangular shell. The mounting shell 221 is slidably connected to the vertical movable frame 12. The front end of the mounting shell 221 is connected to a clamping member 222 that cooperates with the outer connector 21. An adjusting member 223 is connected inside the mounting shell 221.

[0037] The external connector 21 includes a plug plate 211, which is fixedly connected to the rear side of the meter by external fasteners. Two round rods 212 are symmetrically fixedly connected to the rear end face of the plug plate 211, and wedges 213 are symmetrically fixedly connected to both ends of the round rods 212.

[0038] The clamping member 222 includes a folding plate 2221. The rear end face of the vertical section of the folding plate 2221 is connected to the adjusting member 223. Two clamping modules 2222 that cooperate with the round rod 212 are symmetrically connected to the front end face of the vertical section of the folding plate 2221.

[0039] The clamping module 2222 includes an arc-shaped clamping plate 22221. The arc-shaped clamping plate 22221 is an arc and two are arranged symmetrically at the top and bottom. The rear ends of the two arc-shaped clamping plates 22221 are rotatably connected to the folding plate 2221 through short rods. A long plate 22222 is fixedly connected to the outer circumference of the arc-shaped clamping plate 22221. The long plate 22222 and the folding plate 2221 are connected by two push springs 22223 arranged symmetrically on the left and right.

[0040] The adjusting component 223 includes abutment blocks 2231. There are two abutment blocks 2231 that are symmetrically connected and slidably connected within the mounting housing 221. Both abutment blocks 2231 have stepped grooves 2232 that run from front to back. When the two abutment blocks 2231 are joined together, the two stepped grooves 2232 also join together. The front half of the two stepped grooves 2232 is oval and the rear half is circular. The abutment blocks 2231 are connected to the mounting housing 221 by a spring 2233. Both abutment blocks 2231 are connected to positioning modules 2234 that cooperate with circular positioning holes 13. The positioning modules 2234 and the folding plate 2221 are connected to a locking module 2235. The front end of the mounting housing 221 is connected to an adjusting module 2236.

[0041] The positioning module 2234 includes a positioning block 22341, which is cylindrical and slidably connected in the mounting tube. The positioning block 22341 can rotate inside the mounting tube. The positioning block 22341 and the corresponding abutment block 2231 are connected by a second spring 22342, and the positioning block 22341 and the second spring 22342 can rotate relative to each other. The positioning block 22341 has a chamfer that matches the circular positioning hole 13.

[0042] The locking module 2235 includes a slot 22351. The positioning block 22341 has a slot 22351 extending through it. The stepped groove 2232 has a chamfer at one end near the abutment block 2231. A plug rod 22352 is fixedly connected to the vertical section in front of the folding plate 2221. The rear end of the plug rod 22352 has an inclined surface that matches the chamfer on the slot 22351.

[0043] The adjustment module 2236 includes a limiting tube 22361, which is fixedly connected to the front end of the mounting shell 221. A cylindrical seat 22362 is slidably connected inside the limiting tube 22361. A hinge block 22363 is rotatably connected to the front end of the cylindrical seat 22362. The hinge block 22363 and the folding plate 2221 are fixedly connected. A connecting rod 22364 is fixedly connected to the rear end of the cylindrical seat 22362. A strip groove that cooperates with the connecting rod 22364 is opened through the vertical direction on the vertical movable frame 12. The connecting rod 22364 is slidably connected in the strip groove. A limiting piece 22365 that prevents the cylindrical seat 22362 from detaching from the mounting shell 221 is fixedly connected to the rear end of the connecting rod 22364.

[0044] In practice, the installation and wiring of the electricity meter includes the following steps:

[0045] I. Meter Installation: The difficulty of installing and wiring meters varies depending on their location. Meters located in the four corners are more difficult to install and wire due to the relatively small operating space. Taking the installation process of a meter located in the upper left corner as an example, first insert the connector plate 211 into the slot on the back of the meter, and then fix the two together with external fasteners. Next, adjust the vertical movable bracket 12 on the left side, leaving suitable installation space on both sides. Then, slide down the inner connector 22 in the upper left corner to adjust it to a comfortable installation height for the installer. After adjustment, insert the connector plate 211... The two round rods 212 after step 1 are aligned with the two clamping modules 2222 and pressed backward, so that each round rod 212 is engaged between the corresponding two arc-shaped clamping plates 22221. The arc-shaped clamping plates 22221 clamp the round rods 212 under the action of the corresponding two long plates 22222 and two push springs 22223. Since this is used to install the electricity meter, two clamping modules 2222 are set on one folding plate 2221. On the one hand, this ensures the stability of the connection, and on the other hand, it also ensures that the electricity meter and the folding plate 2221 are in a parallel state after the connection is completed, thereby ensuring the accuracy of the installation position.

[0046] During the installation of this meter, the inner connector 22 on the upper left is positioned relatively high. The two abutments 2231 are abutted together under the action of the first spring 2233, and the two positioning blocks 22341 are retracted into the mounting tube under the action of the second spring 22342. However, the ends of the two positioning blocks 22341 also abut between the left and right vertical sections of the vertical movable frame 12. Therefore, after the installer adjusts it to the designated position, the meter can automatically remain stationary in that position without the need for other tools for support. Simultaneously, in this state, the two abutments 2231 are not easily separated due to the compressive force of both the first spring 2233 and the second spring 22342. Open, at this time the two stepped grooves 2232 are spliced ​​together. After splicing, the front half of the two stepped grooves 2232 is oval. Therefore, during the process of installing the round rod 212 to the clamping module 2222, the cylindrical seat 22362 cannot enter the stepped groove 2232. The hinge block 22363 at its front end is located outside the limiting tube 22361, so it can rotate up and down relative to the cylindrical seat 22362. In addition, the folding plate 2221, the clamping module 2222, the outer connector 21 and the meter can also rotate up and down by a certain angle to facilitate subsequent wiring. After installing the upper left meter according to the above operation, install the remaining upper and lower meters to the corresponding inner connectors 22 in the same way.

[0047] The installation method of the meter located in the middle is slightly different from that of the meters above and below. The difference is that the meter in the middle position is easier to wire due to its height relative to the other meters. Therefore, the two positioning blocks 22341 in the inner connector 22 in the middle position are inserted into the corresponding circular positioning holes 13 in the initial state. During the process of installing the round rod 212 into the corresponding clamping module 2222, when performing the backward pressing action, in the first stage of pressing, since the two abutments 2231 are only pressed by the first spring 2233, the cylindrical seat 22 362 will slide backward and first retract into the limiting tube 22361, and then slide between the first half of the two stepped grooves 2232. During this process, the two No. 1 springs 2233 are further compressed, and the two abutments 2231 move in opposite directions under the action of the cylindrical seat 22362. Thus, the No. 2 spring 22342 drives the positioning block 22341 to move out of the mounting tube. At the same time, pressing the meter will also drive the two round rods 212 to move backward, thereby driving the wedges 213 at both ends to slide between the two vertical sections of the vertical movable frame 12, thus automatically adjusting the position of the meter.

[0048] In the later stage of pressing, as the pressing action continues, the beveled surface of the rear end of the insertion rod 22352 will first be brought into contact with the chamfer of the slot 22351. Then, the chamfer of the slot 22351 will slide, thereby causing the positioning block 22341 to slide into the installation tube until the rear end of the insertion rod 22352 is inserted into the slot 22351. This achieves locking between the positioning block 22341, the insertion rod 22352, and the folding plate 2221, thereby enhancing the stability of the meter while ensuring accurate installation.

[0049] 2. Wiring of the electricity meters: After all the electricity meters are installed, first move the vertical movable frame 12 to the designated position, and then move each electricity meter up and down along the vertical movable frame 12 to the position of the circular positioning hole 13. The two positioning blocks 22341 will automatically slide into the corresponding circular positioning hole 13 under the action of the second spring 22342.

[0050] After the upper and lower meters are moved to their designated positions, the hinge block 22363 can rotate up and down because the corresponding cylindrical bases 22362 of these meters are outside the limiting tube 22361. As a result, the folding plate 2221, clamping module 2222, external connector 21, and meters can also rotate up and down by a certain angle. When wiring, the installer can turn the meters up or down as needed to quickly find the hole position, reduce the difficulty of wiring, and avoid wiring errors. At the same time, the round rod 212, located at the front end of the vertical movable frame 12, can also move left and right manually in the clamping state, further reducing the difficulty of wiring. After the wiring is completed, press the meter backward, and then the meter can be locked by the locking module 2235.

[0051] III. Meter Removal: When the meter box needs to be upgraded or repaired, and a meter needs to be replaced, taking the removal of the meter in the upper left corner as an example, simply pull the meter forward first, so that the plug 22352 is pulled out of the slot 22351, thereby releasing the lock on the positioning block 22341. At the same time, the column base 22362 is also pulled out of the limit tube 22361. At this time, the meter returns to a rotatable state, which makes it easier for the installer to disconnect the wires. After disconnecting the wires, force forward to pull the meter out of the clamping module 2222, and the removal of the meter is complete.

[0052] If a new electricity meter needs to be installed, the positioning block 22341 needs to be rotated 180 degrees to switch its chamfer to the bottom. Then, when the folding plate 2221 is pushed down, the positioning block 22341 can retract back into the installation tube under the action of the two side walls of the vertical movable frame 12. This allows the inner connecting piece 22 to slide down along the left side of the vertical movable frame 12 to a height that is convenient for the installer to operate, so as to facilitate the subsequent installation of the electricity meter.

[0053] It is worth noting that the above-mentioned method of disassembling and assembling electricity meters has the following advantages compared to conventional methods:

[0054] Advantage 1: When installing the electricity meter on the vertical movable frame 12, the staff can move the position of the vertical movable frame 12 in the meter box as needed. At the same time, the positions of each internal connecting part 22 on the vertical movable frame 12 can also be moved as needed, thereby reducing the difficulty of installing electricity meters at low or high locations. When installing the electricity meter on the internal connecting part 22, it is only necessary to first fix the external connecting part 21 to the electricity meter, and then fix the two round rods 212 on the external connecting part 21 in the corresponding clamping module 2222. The installation method is relatively simple.

[0055] Advantage 2: After installing each meter onto the corresponding internal connector 22, the meters need to be moved to the designated position. To do this, simply move the vertical movable frame 12 to the designated position first, and then move each meter up and down along the vertical movable frame 12 to the designated position. During the up and down movement of the meters, the two positioning blocks 22341 will automatically slide into the corresponding circular positioning holes 13 after they move to the position of the circular positioning holes 13. Compared with the conventional installation method, this installation and positioning method is simpler and does not require the use of external tools when installing meters located in corners.

[0056] Thirdly, after the electricity meter is moved to the designated location, wiring is required. In conventional wiring methods, when wiring meters at higher locations, installers may sometimes make wiring errors or unstable connections due to limited visibility or insufficient operating space. In this invention, after the electricity meter is moved to a higher location, before it is locked by the locking module 2235, the cylindrical base 22362 is outside the limiting tube 22361. Therefore, the folding plate 2221, clamping module 2222, external connector 21, and electricity meter can also rotate up and down by a certain angle. When wiring, installers can turn the electricity meter up or down as needed to quickly find the hole position. At the same time, before the electricity meter is fixed by the fixing module, even if the round rod 212 is in a clamped state, the installer can push the electricity meter left and right to move it freely within a certain range. After the electricity meter is fixed by the fixing module, the wedges 213 at both ends of the two round rods 212 will automatically correct the position of the electricity meter when it enters the vertical movable frame 12. This ensures accurate installation position, reduces wiring difficulty, and avoids wiring errors.

[0057] Fourthly, after the wiring is completed, pressing the meter backward will first cause the beveled surface of the rear end of the plug 22352 to fit into the chamfer of the slot 22351. Then, the chamfer of the slot 22351 slides, thereby causing the positioning block 22341 to slide into the installation tube until the rear end of the plug 22352 is inserted into the slot 22351, thus achieving the locking between the positioning block 22341, the plug 22352, and the folding plate 2221. The sliding of the positioning block 22341 into the installation tube will also cause the abutment block 2231 to further press against the cylindrical seat 22362 through the second spring 22342, thereby enhancing the installation strength of the meter.

[0058] Fifthly, taking the positioning block 22341 in the inner connector 22 located in the upper left corner as an example, when the meter is in the installation state, the positioning block 22341 is inserted into the corresponding circular positioning hole 13 with the chamfer facing upward, which can stabilize the meter in the designated position. When the meter needs to be replaced, the two positioning blocks 22341 on the left and right sides are rotated 180 degrees simultaneously, and the chamfer is switched to the lower side. When the mounting shell 221 is pushed down, the chamfer of the positioning block 22341 can slide along the circular positioning hole 13, thereby retracting back into the mounting tube. This allows the inner connector 22 to slide down along the vertical movable frame 12 on the left side to a height that is convenient for the installer to operate, so as to facilitate the subsequent installation of the meter.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
