DETAILED DESCRIPTION

[0036] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] Reference Figures 1 to 16 :

[0038] A box-type electric energy meter box, comprising a box body 1, a mounting frame plate 11 for mounting electrical components, a top plate 12 located at the top of the mounting frame plate 11 and a base 13 located at the bottom of the mounting frame plate 11, a plurality of legs 131 are arranged at the bottom of the base 13, at least two vertical longitudinal support plates 14 are arranged on both sides of the box body 1, two main quick-install beams 2 and two auxiliary quick-install beams 3 are horizontally installed on the outer sides of the longitudinal support plates 14 on both sides of the box body 1, and two adjacent box bodies 1 are spliced. When together, the main quick-install beam 2 on one side of the box body 1 is fitted up and down with the auxiliary quick-install beam 3 on the other side of the box body 1, and the fitting sides of the main quick-install beam 2 and the auxiliary quick-install beam 3 are respectively provided with a first insertion hole 21 and an elastic top column 22 on the same straight line, and the elastic top column 22 is inserted into the first insertion hole 21 on the opposite side to fix the two adjacent box bodies 1; the box body 1 is independently installed with a side blocking plate 4 outside the main quick-install beam 2 and the auxiliary quick-install beam 3, and a front cabinet door 5 for blocking the front opening of the box body 1 is hingedly installed on the side blocking plate 4 on one side of the box body 1.

[0039] When the metering box of the present invention is in use, the staff can install various electrical components on the mounting frame 11 inside the box body 1. The mounting frame 11 provides a stable mounting plane for the components. The top plate 12 and the base 13 protect the internal components from the top and bottom directions. The legs 131 of the base 13 isolate the box body 1 from the mounting plane to ensure that it is at a suitable height to avoid moisture and other problems. When there is only a single box body 1, the staff can install the side blocking plates 4 on both sides of the box body 1 outside the main quick-install beam 2 and the auxiliary quick-install beam 3 to enhance the overall sealing and protection. Finally, the front cabinet door 5 hinged on the side blocking plate 4 is opened and closed to operate, maintain and check the electrical components inside the box body 1. When multiple boxes 1 need to be installed in combination, the staff will move one box 1 to the side of another box 1, and remove the side blocking plate 4 on the side where the two boxes 1 fit together, so that the main quick-install beam 2 on one side of the box 1 is aligned with the auxiliary quick-install beam 3 of the adjacent box 1, and the two boxes 1 are pushed together. At this time, the elastic top column 22 on the main quick-install beam 2 will contact the first insertion hole 21 on the auxiliary quick-install beam 3 of the adjacent box 1. As the boxes 1 get closer, the elastic top column 22 is squeezed and contracted until it is fully inserted into the first insertion hole 21, and the two boxes 1 are quickly spliced ​​and fixed by relying on the elastic restoring force. The main quick-install beam 2 and the auxiliary quick-install beam 3 are supported by the longitudinal support plate 14 to ensure the stability and reliability of the connection, thereby completing the combined installation of the adjacent boxes 1, and there is a large gap between the longitudinal support plates 14, which is convenient for connecting the electrical components in the two assembled boxes 1. This embodiment greatly simplifies the assembly and installation process of multiple boxes 1. Through the cooperation of the elastic top column 22 and the first insertion hole 21, the adjacent boxes 1 are quickly and conveniently spliced, without the need for complex tools and a lot of installation time, thus improving work efficiency and reducing labor intensity. Moreover, this connection method is stable and reliable, and can ensure that the assembled boxes 1 remain compact in structure during long-term use, and are not prone to loosening, displacement and other problems, ensuring the electrical connection stability when multiple boxes 1 are used in combination, and facilitating unified management and statistics of the power consumption of multiple electrical devices.

[0040] In order to enable the main quick-install beam 2 and the auxiliary quick-install beam 3 to be quickly installed and connected, the following features are specifically set:

[0041] There are a plurality of first insertion holes 21 and elastic top columns 22, which are distributed along the length direction of the main quick-loading beam 2; the cross-sections of the first insertion holes 21 and the elastic top columns 22 are rectangular, and an installation box 23 aligned with the first insertion hole 21 is provided inside the main quick-loading beam 2, and the installation box 23 is provided with an installation cavity 231 on one side of the first insertion hole 21, and the elastic top column 22 is slidably installed in the installation cavity 231, and a spring 232 is provided in the installation cavity 231, and the spring 232 elastically connects the installation cavity 231 and the bottom of the elastic top column 22, and the elastic force of the spring 232 causes the elastic top column 22 to move toward the side of the first insertion hole 21; an inclined surface 221 and a straight surface 222 are provided on the elastic top column 22, and the elastic top column 22 on the main quick-loading beam 2 and the auxiliary quick-loading beam 3 have inclined surfaces 221 and straight surfaces 222 in opposite positions, and the inclined surfaces 221 on the main quick-loading beam 2 and the auxiliary quick-loading beam 3 are inclined in the same direction.

[0042] When the main quick-loading beam 2 and the auxiliary quick-loading beam 3 of this embodiment are connected, the staff can align one end of the main quick-loading beam 2 and the auxiliary quick-loading beam 3, and the inclined surfaces 221 of the elastic top column 22 on the main quick-loading beam 2 and the auxiliary quick-loading beam 3 are arranged relatively, and then the main quick-loading beam 2 and the auxiliary quick-loading beam 3 are relatively moved along the length direction. As the box body 1 gradually approaches, the inclined surfaces 221 of the elastic top column 22 on the main quick-loading beam 2 and the auxiliary quick-loading beam 3 will contact and squeeze each other. Under the interaction of the inclined surfaces 221, the elastic top column 22 will slide inward along the installation cavity 231, compress the spring 232, and gradually retract the elastic top column 22 into the installation box 23 until the main quick-loading beam 2 and the auxiliary quick-loading beam 3 of the adjacent box body 1 are completely fitted. At this time, the corresponding first insertion hole 21 and the elastic top column 22 are automatically aligned and inserted together under the elastic force of the spring 232, completing the quick connection and fixation. When all the elastic top columns 22 on the opposite side of the main quick-loading beam 2 and the auxiliary quick-loading beam 3 are inserted into the corresponding first insertion holes 21, the main quick-loading beam 2 and the auxiliary quick-loading beam 3 are aligned. Moreover, since there are several first insertion holes 21 and elastic top columns 22 distributed along the length direction of the main quick-loading beam 2, precise connection can be achieved at multiple positions, further ensuring the stability and flatness of the connection.

[0043] Since the inclined surfaces 221 of the elastic top column 22 on the main quick-install beam 2 and the auxiliary quick-install beam 3 are arranged relatively, the main quick-install beam 2 and the auxiliary quick-install beam 3 can move in a single direction. In order to limit the subsequent movement of the main quick-install beam 2 and the auxiliary quick-install beam 3 after the main quick-install beam 2 and the auxiliary quick-install beam 3 are aligned, the following features are specifically set:

[0044] Both ends of the installation box 23 are provided with pins 233 extending toward the side where the main quick-loading beam 2 and the auxiliary quick-loading beam 3 are in contact with each other, and the pins 233 extend through the second insertion holes 24 provided on the first insertion holes 21 to the outside of the main quick-loading beam 2 and the auxiliary quick-loading beam 3; a vertically extending threaded sleeve 25 is provided on the side where the main quick-loading beam 2 and the auxiliary quick-loading beam 3 are in contact with each other, and a first positioning bolt 251 is spirally installed in the threaded sleeve 25, and the first positioning bolt 251 is located at one end of the straight surface 222 of the main quick-loading beam 2 and the auxiliary quick-loading beam 3 close to the outermost elastic top column 22. When the elastic top columns 22 on the main quick-loading beam 2 and the auxiliary quick-loading beam 3 are all inserted into the first insertion holes 21 on the opposite side, the main quick-loading beam 2 and the auxiliary quick-loading beam 3 are aligned, and the first positioning bolt 251 fits the pin 233 on the installation box 23 on the opposite side close to one end of the first positioning bolt 251.

[0045] In this embodiment, when all the elastic top columns 22 are fully inserted into place, the main quick-install beam 2 and the auxiliary quick-install beam 3 are precisely aligned. Since the pins 233 at both ends of the mounting box 23 will pass through the second mounting holes 24 on the first mounting holes 21 and extend to the outside of the main quick-loading beam 2 and the auxiliary quick-loading beam 3; therefore, when the first positioning bolt 251 at one end of the straight surface 222 of the outermost elastic top column 22 on the side where the main quick-loading beam 2 and the auxiliary quick-loading beam 3 are in contact with each other fits into the pin 233 on the opposite side of the mounting box 23 close to the first positioning bolt 251, the movement of the main quick-loading beam 2 and the auxiliary quick-loading beam 3 will be restricted, and since the straight surface 222 of the elastic top column 22 is inserted in the first mounting hole 21, the main quick-loading beam 2 and the auxiliary quick-loading beam 3 cannot move in the opposite direction, so that the positions of the two can be accurately locked, and the subsequent displacement in the single moving direction allowed by the inclined surface 221 of the elastic top column 22 is effectively prevented, so as to avoid loosening and offset between the box bodies 1 due to slight shaking, external force collision, etc. in daily use, thereby ensuring the overall rigidity and structural integrity of the metering box group composed of multiple box bodies 1. When the box body 1 is subsequently disassembled, it is only necessary to remove the first positioning bolt 251 and then drive the main quick-install beam 2 and the auxiliary quick-install beam 3 to continue moving until they are separated.

[0046] In order to prevent the pins 233 protruding from the surface of the main quick-install beam 2 and the auxiliary quick-install beam 3 from affecting the movement of the main quick-install beam 2 and the auxiliary quick-install beam 3, the following features are specifically set:

[0047] At least two parallel heightening strips 26 are arranged on the upper and lower sides of the main quick-install beam 2 and the auxiliary quick-install beam 3. The heightening strips 26 extend along the length direction of the main quick-install beam 2 and the auxiliary quick-install beam 3. When two adjacent box bodies 1 are spliced, the heightening strips 26 on the main quick-install beam 2 and the heightening strips 26 on the auxiliary quick-install beam 3 fit together; the thickness of the heightening strip 26 is greater than the portion of the pin 233 protruding from the surface of the main quick-install beam 2; the portion of the first positioning bolt 251 protruding from the surface of the auxiliary quick-install beam 3 is greater than the thickness of the heightening strip 26.

[0048] When the main quick-install beam 2 and the auxiliary quick-install beam 3 are fitted, the pins 233 at both ends of the installation box 23 extend through the second insertion hole 24, but because the thickness of the heightening strips 26 set on the upper and lower sides of the main quick-install beam 2 and the auxiliary quick-install beam 3 is greater than the portion of the pins 233 protruding from the surface of the main quick-install beam 2, the pins 233 will not interfere with the main quick-install beam 2 or the auxiliary quick-install beam 3 on the opposite side, and will not hinder the movement of the main quick-install beam 2 and the auxiliary quick-install beam 3 during the splicing process, thus ensuring the smooth splicing action. Since the portion of the first positioning bolt 251 protruding from the surface of the auxiliary quick-install beam 3 is greater than the thickness of the heightening strip 26, the first positioning bolt 251 can tightly press against the pins 233, lock the positions of the main quick-install beam 2 and the auxiliary quick-install beam 3, and limit the subsequent possible displacement.

[0049] In order to properly adjust the positions of the main quick-install beam 2 and the auxiliary quick-install beam 3 on the longitudinal support plate 14 according to the actual positions of the electrical components inside the box 1, the following features are specifically set:

[0050] At least two screws 27 are provided on the side of the main quick-loading beam 2 and the auxiliary quick-loading beam 3 facing the longitudinal support plate 14. The screws 27 are arranged in the vertical direction. The screws 27 are inserted into the first waist-shaped limiting holes 141 provided on the longitudinal support plate 14. The first waist-shaped limiting holes 141 extend along the vertical direction. A locking nut 271 is spirally installed on the screw 27. The screw 27 cooperates with the locking nut 271 to lock the positions of the main quick-loading beam 2 and the auxiliary quick-loading beam 3 on the longitudinal support plate 14.

[0051] In this embodiment, when it is necessary to adjust the positions of the main quick-loading beam 2 and the auxiliary quick-loading beam 3 on the longitudinal support plate 14 according to the actual layout of the electrical components inside the box body 1, the staff first loosens the locking nut 271 on the screw 27. Since the screw 27 is inserted into the first waist-shaped limiting hole 141 extending in the vertical direction of the longitudinal support plate 14, the main quick-loading beam 2 and the auxiliary quick-loading beam 3 have a certain vertical movement space. At this time, the staff can move the main quick-loading beam 2 and the auxiliary quick-loading beam 3 up and down along the first waist-shaped limiting hole 141 until they are adjusted to a height that matches the position of the internal electrical components, and ensure that the adjusted main quick-loading beam 2 can be docked with the auxiliary quick-loading beam 3 on the adjacent box body 1. Ensuring that the main quick-loading beam 2 and the auxiliary quick-loading beam 3 on the box body 1 can meet the connection and wiring requirements of the electrical components after positioning is ensured, which is conducive to improving the stability and reliability of the electrical connection after the subsequent splicing of the box body 1, and indirectly ensuring the accuracy of electric energy metering.

[0052] In order to facilitate accurate adjustment of the positions of the main quick-install beam 2 and the auxiliary quick-install beam 3 after the two boxes 1 are spliced, the following features are specifically set:

[0053] The box body 1 is provided with horizontal alignment strips 142 at the upper and lower ends of the longitudinal support plate 14. The alignment strips 142 are parallel to the main quick-install beam 2, and the width of the alignment strip 142 in the horizontal direction is equal to half of the width of the main quick-install beam 2 in the horizontal direction; the alignment strips 142 on both sides of the box body 1 are respectively provided with convex strips 143 and grooves 144 on the side facing outwards, and the convex strips 143 and the grooves 144 have longitudinal sections of the same shape and size.

[0054] In this embodiment, since the alignment strip 142 is parallel to the main quick-install beam 2, when the two boxes 1 are brought close together, the side convex strip 143 is slowly inserted into the corresponding groove 144, and the top plates 12 of the two boxes 1 are aligned, which facilitates more accurate calibration of the positions of the main quick-install beam 2 and the auxiliary quick-install beam 3 of the two boxes 1, and ensures that the elastic top column 22 can be accurately inserted into the first insertion hole 21 to lock the splicing of the two boxes 1. Since the width of the alignment strip 142 in the horizontal direction is equal to half the width of the main quick-install beam 2 in the horizontal direction, it can be ensured that when the alignment strips 142 of the two adjacent boxes 1 are attached together, the longitudinal support plates 14 of the two adjacent boxes 1 are attached to the two sides of the main quick-install beam 2 and the auxiliary quick-install beam 3 respectively.

[0055] In order to facilitate the installation of the side blocking plate 4 on both sides of the metering box formed by splicing any number of boxes 1, the following features are specifically set:

[0056] Mounting cards 121 are provided on both sides of the top of the top plate 12 and the bottom of the base 13. The mounting card 121 has a first slot 122 opening outward. The mounting card 121 and the first slot 122 both extend horizontally along the length direction of the main quick-loading beam 2. A second slot 145 opening downward is provided at the bottom of the alignment strip 142; the upper and lower ends of the side blocking plate 4 are both provided with a horizontally extending first clamping cross plate 41 and a second clamping cross plate 42. The first clamping cross plate 41 and the second clamping cross plate 42 extend along the length direction of the main quick-loading beam 2 and are perpendicular to the side blocking plate 4. The end of the first clamping cross plate 41 away from the side blocking plate 4 is provided with a first right-angle hanging edge 411 for being inserted into the first slot 122, and the end of the second clamping cross plate 42 away from the side blocking plate 4 is provided with a second right-angle hanging edge 421 for being inserted into the second slot 145.

[0057] In this embodiment, after the splicing of several boxes 1 is completed, the side blocking plate 4 is installed. The staff picks up the side blocking plate 4 and aligns it with the assembled box 1. First, the upper end of the side blocking plate 4 is processed, and the first right-angled hanging edge 411 on the first clamping horizontal plate 41 is aligned with the first slot 122 of the clamping plate 121 installed on the top of the top plate 12, and it is pushed horizontally along the length direction of the main quick-install beam 2, so that the first right-angled hanging edge 411 is completely inserted into the first slot 122; at the same time, the second right-angled hanging edge 421 of the second clamping horizontal plate 42 is aligned with the second slot 145 at the bottom of the alignment strip 142, and is also inserted horizontally along the length direction of the main quick-install beam 2 until the second right-angled hanging edge 421 is firmly inserted into the second slot 145. The staff only needs to push horizontally to complete the clamping of the side blocking plate 4 using the first right-angled hanging edge 411 and the second right-angled hanging edge 421. The operation is simple and quick, and no complicated tools or fine alignment are required, which reduces the difficulty and time cost of installation and improves the installation efficiency.

[0058] In order to facilitate heat dissipation in the box 1, the following features are specifically set:

[0059] The side blocking plate 4 is provided with a heat dissipation hole 43 , and a heat dissipation fan 431 is installed in the heat dissipation hole 43 .

[0060] In order to facilitate closing the front opening of a single or multiple boxes 1, the following features are specifically provided:

[0061] The front cabinet door 5 includes a hinged panel 51 hinged to the side blocking plate 4 on one side of the box body 1, and a movable panel 52 slidably installed on the hinged panel 51. A vertical hinge rod 511 is provided on one side of the hinged panel 51, and the hinged panel 51 is hingedly installed on a vertically extending hinge seat 44 provided on the side blocking plate 4 through the hinge rod 511; horizontally extending limiting slide rails 512 are provided at the upper and lower ends of the hinged panel 51, and the movable panel 52 is slidably installed in the limiting slide rails 512.

[0062] The part of the hinged panel 51 located in the limiting slide rail 512 is provided with a first positioning hole 513 and a second positioning hole 514 distributed along the length direction of the limiting slide rail 512, and the part of the movable plate 52 located in the limiting slide rail 512 is provided with a threaded hole 521. The first positioning hole 513, the second positioning hole 514 and the threaded hole 521 have the same diameter, and a second positioning bolt 522 is screwedly installed at the threaded hole 521; when the second positioning bolt 522 is inserted into the first positioning hole 513 and the threaded hole 521, the movable plate 52 is away from the hinged panel 51. One end of the rod 511 is aligned with the outer side of the side blocking plate 4 of the box body 1 away from the hinge rod 511; when the second positioning bolt 522 is inserted into the second positioning hole 514 and the threaded hole 521, the end of the movable plate 52 away from the hinge rod 511 is aligned with the outward side of the alignment strip 142 of the box body 1 away from the hinge rod 511; the limiting slide rail 512 is provided with a second waist-shaped limiting hole 515 with the first positioning hole 513 and the second positioning hole 514 as end points, and the second positioning bolt 522 is located in the second waist-shaped limiting hole 515 and moves.

[0063] The hinged panel 51 in this embodiment is connected to the hinge seat 44 of the side blocking plate 4 through the hinge rod 511, and the movable plate 52 slides in the limiting slide rail 512, so that the opening size of the front cabinet door 5 is no longer fixed. It is convenient to close the front opening of a single or multiple boxes 1. The staff can unscrew the second positioning bolt 522, and then slide the movable plate 52 along the limiting slide rail 512. After the two boxes 1 are spliced, the staff installs the front cabinet door 5 on the side blocking plates 4 on both sides of the spliced ​​box 1. The two front cabinet doors 5 are open to each other. Therefore, when the movable plate 52 moves to the end away from the hinge rod 511 and is aligned with the side of the alignment strip 142 on the side of the box 1 away from the hinge rod 511, the two front cabinet doors 5 can completely block the front opening of the box 1 after closing. At this time, the second positioning bolt 522 is inserted into the second positioning hole 514 and the threaded hole 521, and tightened to fix. Similarly, when the front cabinet door 5 only needs to block a single box 1, the second positioning bolt 522 is also loosened first, and the movable plate 52 is slid to align the end away from the hinge rod 511 with the outer side of the side blocking plate 4 of the box 1 away from the hinge rod 511, and then the second positioning bolt 522 is inserted into the first positioning hole 513 and the threaded hole 521, and tightened to ensure that the front cabinet door 5 completely blocks the front opening of the box 1. In this embodiment, the first positioning hole 513 and the second positioning hole 514 on the hinged panel 51 provide two clear and precise stop positions for the movable plate 52. By inserting the second positioning bolt 522, the movable plate 52 can be quickly and accurately fixed in the required opening size state, meeting the strict requirements on the opening size in different operation scenarios.

[0064] Working principle: The staff installs various electrical components on the mounting frame 11 inside the box 1. The mounting frame 11 provides a stable mounting plane for the components. When there is only a single box 1, the staff can install the side blocking plates 4 on both sides of the box 1 outside the main quick-install beam 2 and the auxiliary quick-install beam 3 to close both sides of the box 1. The front cabinet door 5 hinged on the side blocking plates 4 is opened and closed to operate, maintain and check the electrical components inside the box 1. When multiple boxes 1 need to be installed in combination, the staff will move one box 1 to one side of another box 1, and remove the side blocking plate 4 on one side of the two boxes 1 to align the main quick-install beam 2 on one side of the box 1 with the auxiliary quick-install beam 3 of the adjacent box 1, and push the two boxes 1 together. At this time, the elastic top column 22 on the main quick-install beam 2 will contact the first insertion hole 21 on the auxiliary quick-install beam 3 of the adjacent box 1. As the boxes 1 get closer, the elastic top column 22 is squeezed and contracted until it is fully inserted into the first insertion hole 21, and the two boxes 1 are quickly spliced ​​and fixed by relying on the elastic restoring force, completing the combined installation of the adjacent boxes 1.
