Description

Technical Field

[0001] The present invention relates to the field of electrical equipment, and in particular to an electric meter box with a modular adjustable internal layout structure. Background Art

[0002] An electric meter box is a device used to house and protect electric meters. It is usually installed outside or inside residential, commercial or industrial buildings. Electrical components such as electric meters, circuit breakers, isolation terminals and terminal blocks are usually installed inside.

[0003] Currently, when installing an electric meter in an electric meter box, it is necessary to first place the electric meter in a designated position of the electric meter box, then fix the electric meter in the electric meter box with screws or other fixing devices, and finally connect the wires. During the above installation process, in order to facilitate maintenance, the installation of the electric meter in the electric meter box is usually relatively compact. Therefore, when installing an electric meter near the top or near the bottom, the space is relatively narrow, which limits the range of movement of the installer's hands, and thus restricts the use of tools to tighten the screws. Moreover, when wiring the electric meter above, it is difficult to clearly see the terminal blocks and markings due to obstructed vision, which increases the risk of connection errors. Summary of the Invention

[0004] In response to the above-mentioned shortcomings of the prior art, the present invention provides a mold processing optimization system based on a rotary punching structure, which can effectively solve the problem in the prior art that when installing electric meters, the use of tools is obstructed and the line of sight is blocked due to insufficient space, which in turn leads to inconvenience in operation.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: An electric meter box with a modular adjustable internal layout structure, comprising: The support part includes a horizontal fixed frame, two of which are evenly fixed and connected up and down, and multiple vertical movable frames are connected to the two horizontal fixed frames for sliding left and right. The vertical movable frames are U-shaped, and three circular positioning holes are evenly and symmetrically opened on the two vertical sections corresponding to the vertical movable frames from top to bottom.

[0006] The connecting part includes an external connecting piece, which is connected to the electric meter through a fastener. Three internal connecting pieces are installed on the vertical movable frame, and the internal connecting pieces are detachably connected to the external connecting pieces.

[0007] Among them, the internal connecting part includes a mounting shell, which is composed of a rectangular shell and two mounting tubes that are symmetrically fixed and connected on both sides of the rectangular shell. The mounting shell is connected to the vertical movable frame by sliding up and down. The front end of the mounting shell is connected to a clamping part that cooperates with the external connecting part, and an adjusting part is connected inside the mounting shell.

[0008] Furthermore, the external connection member includes a plug-in board, which is fixedly connected to the rear side of the electric meter through external fasteners. Two round rods are symmetrically fixedly connected to the rear end surface of the plug-in board, and wedges are symmetrically fixedly connected to both ends of the round rods.

[0009] Furthermore, the clamping member includes a folding plate, the rear end surface of the vertical section behind the folding plate is connected to the adjusting member, and the front end surface of the vertical section behind the folding plate is symmetrically connected to two clamping modules that match the round rod.

[0010] Furthermore, the clamping module includes an arc-shaped clamping plate, which is a superior arc and is symmetrically arranged in two pieces up and down. The rear ends of the two arc-shaped clamping plates are rotatably connected to the folding plate through short rods. The circumferential outer surface of the arc-shaped clamping plate is fixedly connected to a long plate. The long plate and the folding plate are connected by two push springs symmetrically arranged on the left and right.

[0011] Furthermore, the adjusting part includes a stop block, and there are two stop blocks that are symmetrical on the left and right and are slidably connected in the mounting shell. A stepped groove is provided on the two stop blocks from front to back, and the two stepped grooves are also spliced ​​after the two stop blocks are spliced ​​together. After the two step grooves are spliced ​​together, the front half of the two step grooves is oval and the back half is circular. The stop block is connected to the mounting shell through a No. 1 spring, and the two stop blocks are connected with a positioning module that matches the circular positioning hole. The positioning module and the folding plate are jointly connected with a locking module, and the front end of the mounting shell is connected with an adjustment module.

[0012] Furthermore, the positioning module includes a positioning block, which is cylindrical and slidably connected in the mounting tube, and the positioning block can rotate in the mounting tube. The positioning block is connected to the corresponding stop block through a No. 2 spring, and the positioning block and the No. 2 spring can rotate relative to each other. The positioning block is provided with a chamfer that matches the circular positioning hole.

[0013] Furthermore, the locking module includes a slot, a slot is provided on the positioning block running through the front and back, a chamfer is provided on one end of the stepped groove near the stop block, an insertion rod is fixedly connected to the vertical section in front of the folding plate, and the rear end of the insertion rod is provided with an inclined surface that matches the chamfer on the slot.

[0014] Furthermore, the adjustment module includes a limiting tube, which is fixedly connected to the front end of the mounting shell, and a cylindrical seat is slidably connected in the limiting tube. The front end of the cylindrical seat is rotatably connected to a hinge block, and the hinge block and the folding plate are fixedly connected. The rear end of the cylindrical seat is fixedly connected to a connecting rod, and a strip groove that cooperates with the connecting rod is opened on the vertical movable frame in the up and down directions. The connecting rod is slidably connected to the strip groove, and the rear end of the connecting rod is fixedly connected to a limiting plate that prevents the cylindrical seat from detaching from the mounting shell.

[0015] The technical solution provided by the present invention has the following beneficial effects compared with the prior art: when the staff installs the electric meter on the vertical movable frame, the position of the vertical movable frame in the electric meter box can be moved as needed, and the position of each internal connecting part on the vertical movable frame can also be moved as needed, thereby reducing the difficulty of installing the electric meter at a low or high place. When installing the electric meter on the internal connecting part, it is only necessary to first fix the external connecting part to the electric 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 specified position respectively. Then, before they are locked by the locking module, the cylindrical seat is outside the limiting tube, so that the folding plate, the clamping module, the external connecting part and the electric meter can also be rotated up and down by a certain angle. When wiring, the installer can turn the electric meter up or down as needed to quickly find the hole position, reducing the difficulty of wiring and avoiding wiring errors.

[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Example:

[0022] See Figures 1-8 , an electric meter box with a modular adjustable internal layout structure, comprising: The support part 1 includes a horizontal fixed frame 11, two of which are evenly fixed and connected up and down, and a plurality of vertical movable frames 12 are connected to the two horizontal fixed frames 11 for sliding left and right. The vertical movable frames 12 are U-shaped, and three circular positioning holes 13 are evenly and symmetrically opened on the two vertical sections corresponding to the vertical movable frames 12 from top to bottom.

[0023] The connecting part 2 includes an external connecting piece 21 , which is connected to the electric meter via a fastener. Three internal connecting pieces 22 are installed on the vertical movable frame 12 , and the internal connecting pieces 22 are detachably connected to the external connecting piece 21 .

[0024] When initially installing the electric meter, the three vertical movable frames 12 are adjusted to a position near the center of the meter box, and the internal connecting parts 22 located above and below are also adjusted to a height that is convenient for operation. Before installing the electric meter, each electric meter is first installed and fixedly connected to the external connecting parts 21, and then the external connecting parts 21 are connected to the internal connecting parts 22. During the installation process, in order to facilitate installation, the electric meters located on the vertical movable frames 12 on both sides are first installed, and after the installation is completed, the vertical movable frames 12 on both sides are moved to the designated position. After the installation on both sides is completed, the electric meter is installed on the middle vertical movable frame 12. Compared with the conventional installation method, this installation method can avoid the situation where the electric meters in the meter box are arranged more compactly and the space on the left and right sides is small and inconvenient for installation.

[0025] After the above installation is completed, slide each meter up and down along each vertical movable frame 12 to adjust it to the specified position. After reaching the specified position, the internal connecting piece 22 cooperates with the circular positioning hole 13 to automatically engage. At this time, the meter can still be rotated up and down by a certain angle to facilitate the installation personnel to connect the wires. After the wiring is completed, press the meter to fix the meter through the internal connecting piece 22.

[0026] Among them, the internal connecting part 22 includes a mounting shell 221, which is composed of a rectangular shell and two mounting tubes that are symmetrically fixed and connected on both sides of the rectangular shell. The mounting shell 221 is connected to the vertical movable frame 12 by sliding up and down. The front end of the mounting shell 221 is connected to a clamping part 222 that cooperates with the external connecting part 21, and an adjusting part 223 is connected inside the mounting shell 221.

[0027] The external connection member 21 includes a plug-in board 211, which is fixedly connected to the rear side of the electric meter through external fasteners. Two round rods 212 are symmetrically fixedly connected to the rear end surface of the plug-in board 211, and wedge blocks 213 are symmetrically fixedly connected to the two ends of the round rods 212.

[0028] The clamping member 222 includes a folding plate 2221 , the rear end surface of the vertical section of the folding plate 2221 is connected to the adjusting member 223 , and the front end surface of the vertical section of the folding plate 2221 is symmetrically connected to two clamping modules 2222 that cooperate with the round rod 212 .

[0029] The clamping module 2222 includes an arc-shaped splint 22221, which is a superior arc and two of which are symmetrically arranged up and down. The rear ends of the two arc-shaped splints 22221 are rotatably connected to the folding plate 2221 through short rods. The circumferential outer surface of the arc-shaped splint 22221 is fixedly connected with a long plate 22222. The long plate 22222 and the folding plate 2221 are connected by two push springs 22223 symmetrically arranged on the left and right.

[0030] The adjusting member 223 includes a stop block 2231, and there are two stop blocks 2231 that are symmetrical and slidingly connected in the mounting shell 221. A stepped groove 2232 is provided from front to back on the two stop blocks 2231, and after the two stop blocks 2231 are spliced ​​together, the two stepped grooves 2232 are also spliced ​​together, and after the two stepped grooves 2232 are spliced ​​together, the front half of the two stepped grooves 2232 are oval and the back half is circular. The stop block 2231 is connected to the mounting shell 221 through a No. 1 spring 2233, and the two stop blocks 2231 are both connected with a positioning module 2234 that matches the circular positioning hole 13. The positioning module 2234 and the folding plate 2221 are jointly connected with a locking module 2235, and the front end of the mounting shell 221 is connected with an adjusting module 2236.

[0031] The positioning module 2234 includes a positioning block 22341, which is cylindrical and slidably connected in the mounting tube, and the positioning block 22341 can rotate in the mounting tube. The positioning block 22341 is connected to the corresponding stop block 2231 through a No. 2 spring 22342, and the positioning block 22341 and the No. 2 spring 22342 can rotate relative to each other. The positioning block 22341 is provided with a chamfer that matches the circular positioning hole 13.

[0032] The locking module 2235 includes a slot 22351, a slot 22351 is provided on the positioning block 22341 from front to back, a chamfer is provided on the end of the stepped groove 2232 close to the stop block 2231, and an insertion rod 22352 is fixedly connected to the vertical section in front of the folding plate 2221, and the rear end of the insertion rod 22352 is provided with an inclined surface that matches the chamfer on the slot 22351.

[0033] 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 in the limiting tube 22361. The front end of the cylindrical seat 22362 is rotatably connected to a hinge block 22363. The hinge block 22363 and the folding plate 2221 are fixedly connected. The rear end of the cylindrical seat 22362 is fixedly connected to a connecting rod 22364. A strip groove that matches the connecting rod 22364 is opened on the vertical movable frame 12 in the up and down directions. The connecting rod 22364 is slidably connected in the strip groove. The rear end of the connecting rod 22364 is fixedly connected to a limiting piece 22365 that prevents the cylindrical seat 22362 from detaching from the mounting shell 221.

[0034] In practice, the installation and wiring of the meter includes the following steps: 1. Installation of electric meters: The installation and wiring difficulty of electric meters in different locations are different. Among them, the electric meters located in the four corners are more difficult to install and wire because the operating space is relatively small. Taking the installation process of the electric meter located in the upper left as an example, first plug the plug board 211 into the slot on the rear side of the electric meter, and then fix the two together with external fasteners. Then adjust the vertical movable frame 12 on the left to reserve appropriate installation space on its left and right sides, and then slide the upper left inner connecting piece 22 downward to adjust it to a more comfortable installation height for the installer. After the adjustment is completed, plug the plug board 211 into the slot on the rear side of the electric meter. The two round rods 212 at the back of 1 are aligned with the two clamping modules 2222 and pressed backward, so that each round rod 212 is clamped between the corresponding two arc-shaped clamping plates 22221, and the arc-shaped clamping plates 22221 clamp the round rod 212 under the action of the corresponding two long plates 22222 and two push springs 22223. Since the installation of the electric meter is achieved in this way, two clamping modules 2222 are provided on a folding plate 2221. On the one hand, the stability of the connection is guaranteed, and on the other hand, the electric meter and the folding plate 2221 are in a parallel state after the connection is completed, thereby ensuring the accuracy of the installation position.

[0035] During the installation of the electric meter, the inner connecting piece 22 on the upper left is located in a relatively upper position, and the two abutting blocks 2231 are abutted together under the action of the No. 1 spring 2233, and the two positioning blocks 22341 are retracted in the installation tube under the action of the No. 2 spring 22342, but the ends of the two positioning blocks 22341 are also abutted between the left and right vertical sections of the vertical movable frame 12. Therefore, after the installer adjusts it to the specified position, the electric meter can automatically remain stationary in this position without the need for other tools to support it. At the same time, in this state, the two abutting blocks 2231 are not easily separated from each other due to the compression force of the No. 1 spring 2233 and the No. 2 spring 22342 at the same time. Open, at this time the two stepped grooves 2232 are spliced ​​together, and the front half of the two stepped grooves 2232 after splicing are oval, so in the process of installing the round rod 212 to the clamping module 2222, the cylindrical seat 22362 cannot enter the stepped groove 2232, and the hinge block 22363 at its front end is located outside the limiting tube 22361 so that it can rotate up and down relative to the cylindrical seat 22362, and then the folding plate 2221, the clamping module 2222, the external connecting piece 21 and the electric meter can also be rotated up and down by a certain angle to facilitate subsequent wiring. After installing the upper left electric meter according to the above operation, install the remaining upper and lower electric meters to the corresponding internal connecting piece 22 in the same way.

[0036] The installation method of the electric meter in the middle is slightly different from that of the electric meters above and below. The difference is that the electric meter in the middle is more convenient to connect due to its height relative to the electric meters in other positions. Therefore, the two positioning blocks 22341 in the inner connecting piece 22 in the middle are inserted into the corresponding circular positioning holes 13 in the initial state. In the process of installing the round rod 212 to the corresponding clamping module 2222, when the backward pressing action is implemented, in the previous stage of pressing, since the two blocking blocks 2231 are only pressed by the No. 1 spring 2233, the cylindrical seat 22 362 will slide backward and first retract into the limit tube 22361, and then slide to between the front halves of the two stepped grooves 2232. During this process, the two No. 1 springs 2233 are further compressed, and the two resisting blocks 2231 move back to back under the action of the cylindrical seat 22362, thereby driving the positioning block 22341 to move outside the installation tube through the No. 2 spring 22342. At the same time, pressing the electric meter will also drive the two round rods 212 to move backward, thereby driving the wedge blocks 213 at both ends to slide between the left and right vertical sections of the vertical movable frame 12, thereby automatically adjusting the position of the electric meter.

[0037] In the latter stage of pressing, as the pressing action continues, the inclined surface at the rear end of the insertion rod 22352 will first fit into the chamfer of the slot 22351, and then the chamfer of the slot 22351 will slide, thereby driving 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, thereby realizing the locking between the positioning block 22341, the insertion rod 22352 and the folding plate 2221, thereby enhancing the stability of the electric meter while ensuring the accuracy of the installation position.

[0038] 2. Wiring of the electric meters: After all the electric meters are installed, first move the vertical movable frame 12 to the designated position, then move each electric meter up and down along the vertical movable frame 12 to move it to the position of the circular positioning hole 13. The two positioning blocks 22341 automatically slide into the corresponding circular positioning holes 13 under the action of the No. 2 spring 22342.

[0039] After moving the upper and lower meters to designated positions, since the cylindrical seats 22362 corresponding to these meters are located outside the limiting tube 22361, the hinge block 22363 can be rotated up and down, so the folding plate 2221, the clamping module 2222, the external connection part 21 and the meter can also be rotated up and down by a certain angle. When wiring, the installer can turn the meter up or down as needed to quickly find the hole position, reducing the difficulty of wiring and avoiding wiring errors. At the same time, since the round rod 212 is located at the front end of the vertical movable frame 12, it can also move left and right under manual push 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 through the locking module 2235.

[0040] 3. Removal and replacement of the electric meter: When the electric meter box needs to be upgraded or repaired and one of the electric meters needs to be replaced, taking the removal of the electric meter on the upper left as an example, when removing it, you only need to pull the electric meter forward first, so that the insertion rod 22352 is pulled out of the slot 22351 to release the lock on the positioning block 22341, and at the same time the cylindrical seat 22362 is also pulled out from the limiting tube 22361. At this time, the electric meter is restored to a rotatable state, so that the installer can remove the wires. After the wires are removed, the electric meter can be pulled out of the clamping module 2222 by applying forward force, and the removal of the electric meter is completed.

[0041] If a new electricity meter needs to be installed, the positioning block 22341 needs to be rotated 180 degrees first, and its chamfer needs to be switched to the bottom. Then, when the folding plate 2221 is pushed downward, the positioning block 22341 can be retracted back into the installation tube again under the action of the two side walls of the vertical movable frame 12, and the internal connecting part 22 can be slid down along the left 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.

[0042] It is worth mentioning that the above-mentioned disassembly and assembly of the electric meter has the following advantages over the conventional disassembly and assembly method: Advantage 1. When installing the electric meter on the vertical movable frame 12, the staff can move the position of the vertical movable frame 12 in the electric meter box as needed, and can also move the position of each internal connecting member 22 on the vertical movable frame 12 as needed, thereby reducing the difficulty of installing the electric meter at a low or high place. When installing the electric meter on the internal connecting member 22, it is only necessary to first fix the external connecting member 21 to the electric meter, and then fix the two round rods 212 on the external connecting member 21 in the corresponding clamping module 2222. The installation method is relatively simple.

[0043] Advantage 2: After each electric meter is installed on the corresponding internal connecting piece 22, the electric meter needs to be moved to the designated position. When moving, you only need to move the vertical movable frame 12 to the designated position first, and then move each electric meter up and down along the vertical movable frame 12 to move it to the designated position. In the process of moving the electric meter up and down, the two positioning blocks 22341 will automatically slide into the corresponding circular positioning holes 13 after moving to the position of the circular positioning holes 13. Compared with the conventional installation method, this installation and positioning method does not require the use of external tools when installing the electric meter located in the corner, and is also relatively simple.

[0044] Advantage 3: After the electric meter is installed and moved to the specified position, wiring is required. When wiring an electric meter at a higher place using the conventional wiring method, the installer may sometimes make wiring errors or unstable connections due to limited vision or insufficient operating space. In the present invention, after the high-place electric meter is moved to a higher place and before it is locked by the locking module 2235, the cylindrical seat 22362 is outside the limiting tube 22361, so that the folding plate 2221, the clamping module 2222, the external connecting piece 21 and the electric meter can also be rotated up and down by a certain angle. When wiring, the installer can turn the electric meter up or down as needed to quickly find the hole position. At the same time, before fixing the electric meter by the fixing module, even if the round rod 212 is in a clamping state, the installer can push the electric meter left and right to make it move freely within a certain range. After the electric meter is fixed by the fixing module, the wedge blocks 213 at both ends of the two round rods 212 will automatically correct the position of the electric meter when entering the vertical movable frame 12, thereby reducing the difficulty of wiring while ensuring the accuracy of the installation position, and also avoiding the occurrence of wiring errors.

[0045] Advantage 4: After the wiring is completed, pressing the electric meter backward will first drive the inclined surface of the rear end of the plug rod 22352 to fit into the chamfer of the slot 22351, and then the chamfer of the slot 22351 will slide, thereby driving the positioning block 22341 to slide into the installation tube until the rear end of the plug rod 22352 is inserted into the slot 22351, thereby achieving locking between the positioning block 22341, the plug rod 22352 and the folding plate 2221. The sliding of the positioning block 22341 into the installation tube will also drive the block 2231 to further tighten the cylindrical seat 22362 through the No. 2 spring 22342, thereby enhancing the installation strength of the electric meter.

[0046] Advantage 5. Taking the positioning block 22341 located in the upper left inner connecting piece 22 as an example, when the electric meter is in the installation state, the positioning block 22341 is inserted into the corresponding circular positioning hole 13 with the chamfer facing upward, so that the electric meter can be stabilized in the specified position. When the electric meter needs to be replaced, the left and right positioning blocks 22341 are rotated 180 degrees synchronously to switch the chamfer to the bottom. When the mounting shell 221 is pushed downward, the chamfer of the positioning block 22341 can slide along the circular positioning hole 13, thereby shrinking back into the mounting tube, and the inner connecting piece 22 can slide downward along the vertical movable frame 12 on the left to a height that is convenient for the installer to operate, so as to facilitate the subsequent installation of the electric meter.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
