[0026] Next, the relevant technical solutions will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work belong to the scope of protection of the present utility model.

[0027] Embodiment 1. As Figure 1 shown, the power equipment box body disclosed in this embodiment is applied to an electric energy meter, and includes an electric energy meter housing 1, a terminal box 2, a hole alignment plate 3, and a terminal box cover 4.

[0028] The electric energy meter housing 1 is a rectangular hollow box with one side open, and it is fixedly covered on the electric energy meter.

[0029] As Figure 2 shown, the terminal box 2 is arranged on one side of the electric energy meter housing, and a connecting cylinder 21, a compression spring 22, a connecting screw 23, a wiring screw 24, and a card slot 25 are arranged in the terminal box.

[0030] A hollow connecting cylinder 21 is arranged at the central position of the terminal box 2 on the side of the electric energy meter housing, and a thread is arranged at the lower part of the inner cavity of the connecting cylinder; the bottom end of the compression spring 22 is fixed at the top end of the threaded section in the connecting cylinder, and there is a gap between the compression spring and the inner wall of the connecting cylinder.

[0031] The top of the connecting screw 23 has a lead seal threading hole at its large head, and the diameter of the bottom screw is slightly smaller than the diameter of the compression spring 22. The connecting screw can be screwed into the connecting cylinder and is threadedly connected to the lower part of the connecting cylinder. The large head of the connecting screw compresses the compression spring downward.

[0032] Inside the terminal box 2, multiple rows of connection screws 24 are arranged. The number and arrangement of the connection screws are related to the corresponding electrical energy equipment.

[0033] On the side of the terminal box 2 away from the electricity meter housing, there are two inverted L-shaped card slots 25, and a tension spring (not shown in the figure) is provided below the card slots. The card slots are used to clamp the alignment plate 3.

[0034] Both ends of the terminal box 2 are respectively provided with connection threaded holes for fixing the terminal box cover 4.

[0035] As Figure 3 shown, the alignment plate 3 is made of a transparent insulating material, and its side cross-section is a right trapezoid. The long side of the trapezoid is the thick side of the alignment plate, and the short side is the thin side of the alignment plate. The thick side of the alignment plate is attached to one side of the card slot of the terminal box 2, and the thin side rises and falls with the thick side as the axis.

[0036] Multiple screwdriver holes 31 are provided on the alignment plate. The positions of the screwdriver holes can correspond one by one to the connection screws 24 on the terminal box.

[0037] A lead seal fixing screw 32 is also provided on the alignment plate 3, located at the center position on the thin side of the alignment plate. A lead seal threading hole is provided on the fixing screw. A connection hole is provided beside the lead seal fixing screw.

[0038] As Figure 4 shown, the terminal box cover 4 is a U-shaped plate, and L-shaped covers are provided on the inner cavities of its two side plates. A sandwich layer 41 is provided on the cover. The sandwich layer is made of a transparent material, one end of which is fixed to the cover through a shaft, and the other end can rotate and open and close with the shaft as the center. A label paper for recording information is provided inside the sandwich layer.

[0039] One fixing hole is provided on each of the two covers of the terminal box cover. The cover fixing screw 42 passes through the fixing hole and is engaged and connected to the connection threaded hole on the terminal box. A lead seal threading hole is provided on the cover fixing screw.

[0040] The ends of the fixing screw, the fixing screw, and the connecting screw are made of a metal structure, with high strength to avoid damage.

[0041] When installing and fixing the electrical energy equipment box body of this embodiment, the following steps are adopted:

[0042] 1. Lean the thick side of the alignment plate against the card slot and connect it to the tension spring below the card slot; the connecting screw passes through the connection hole on the alignment plate and the compression spring on the terminal box, and is threadedly connected to the lower part of the inner cavity of the connecting cylinder to limit the alignment plate.

[0043] 2. Tighten the connecting screw rod to lower the thin edge of the orifice plate, so that the orifice plate maintains a horizontal balance state.

[0044] 3. Pass the two fixing screw rods of the terminal box cover through the fixing holes of the terminal box cover and connect them to the connecting threaded holes on the terminal box to limit the terminal box cover.

[0045] 4. Set the required label paper in the sandwich layer of the terminal box cover.

[0046] When using the electrical energy equipment box of this embodiment:

[0047] 1. Displace the thin edge of the orifice plate up and down by turning the connecting screw rod; first, make the orifice plate in a horizontal balance state, and the screwdriver hole of the orifice plate can be aligned with the wiring screw of the terminal box. At this time, the staff can operate the screwdriver to turn the wiring screw of the terminal box.

[0048] 2. Then tighten the connecting screw rod to the tightest. At this time, the position of the thin edge of the orifice plate is the lowest, and the screwdriver hole of the orifice plate is maximally staggered from the wiring screw of the terminal box, and the two cannot be aligned.

[0049] 3. Let the lead seal wire pass through the lead seal wire passing holes on the connecting screw rod and the fixing screw at the same time, and tie the two components with a lead seal.

[0050] 4. Finally, use the lead seal wire to lock the two fixing screw rods on the terminal box cover.

[0051] After the electrical energy equipment box body of this embodiment is installed, a screw tightness detection tool 5 can be used to detect the tightness of each wiring screw.

[0052] As Figure 5 and Figure 6 shown, the screw tightness detection tool 5 includes a base 51, a hollow rod 52 and a sensor 53.

[0053] The top surface of the base 51 is a numerical display panel, and a plurality of hollow rods 52 are arranged on the bottom surface. The number and position of the hollow rods correspond one by one to the number and position of the screwdriver holes of the orifice plate; the hollow rods are made of insulating materials, and wires can pass through the middle. The diameter of the hollow rod is slightly smaller than the diameter of the screwdriver hole of the orifice plate.

[0054] Sensors 53 are arranged at the ends of the hollow rods 52. The sensors are distributed flexible film micro pressure sensors, and the outer layer of the sensors has an insulating film.

[0055] When using this detection tool, insert the hollow rods on the back of the base into the screwdriver holes of the hole plate, and make the sensor contact the wiring screw. The sensor is in an open state under natural conditions with infinite resistance. When the external pressure reaches a certain value, the sensor is triggered and jumps from the open state to the pressure-sensitive conduction state. The output resistance of the lead end changes accordingly with the change of the external pressure. The greater the pressure, the smaller the resistance value. A working voltage of 3 - 5V and other circuits are used to convert the pressure signal sensed by the sensor into an electrical signal with a corresponding change in intensity for output.

[0056] The pressure between the wiring screw can be read through the top surface of the base. The greater the pressure, the looser the wiring screw; the smaller the pressure, the tighter the wiring screw.

[0057] Embodiment 2: As Figure 7 shown, the electrical energy equipment box body disclosed in this embodiment is applied to a junction box, and includes a junction box 6, a hole plate 7, and a junction box cover 8.

[0058] As Figure 8 shown, the junction box 6 is a rectangular hollow box with an open bottom. The junction box covers the electrical energy equipment to enclose various electrical energy equipment. Inside the junction box, there are a connecting cylinder, a compression spring, a connecting screw rod, and a wiring screw with the same structure as those in the terminal box 2.

[0059] On both sides of the junction box 6, there are also two groups of connection holes through which the junction box cover 8 can be connected and fixed by the connecting screw rod. The top end of the connecting screw rod is provided with a lead seal hole.

[0060] On both sides of the junction box, there are also U-shaped mounting holes through which the junction box is installed at a suitable position on metering boxes, cabinets, panels, etc.

[0061] As Figure 9 shown, the hole plate 7 is similar in structure to the hole plate 3. The number and positions of the screwdriver holes on the hole plate are the same as those of the wiring screws on the junction box 6.

[0062] As Figure 10 shown, the junction box cover 8 is a rectangular plate. On both sides of it, there are rectangular interlayers made of transparent materials. One end of the interlayer is fixed to the junction box cover through a shaft, and the other end can rotate and open and close with the shaft as the center. Inside the interlayer, there is a label paper for recording information.

[0063] On both sides of the junction box cover, there are also ear seats through which the connecting screw rod can pass through the ear seats, the hole plate, and the junction box to limit and connect the three.

[0064] The advantages of using this embodiment compared with Embodiment 1 are as follows:

[0065] In this embodiment, the connection screw is directly arranged on the box body, so that the overall structural strength of the box body is higher, the installation of the orifice plate is more stable, and it can be applied to various electrical energy devices with better adaptability. However, the disadvantage is that the original box body needs to be completely discarded and a new box body needs to be set up. While the box body of the first embodiment can be refitted based on the original box body, which is more economical and practical and more convenient to install.

[0066] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the foregoing embodiments have been described in detail, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
