[0014] With the above scheme, the four outlet holes correspond to four installation devices, and the wires extending from the outlet holes are connected to each corresponding electricity meter.

[0015] Furthermore, fasteners are fixedly installed inside the housing.

[0016] The above method uses a nested fastener with a conduit extending into the housing to secure the conduit.

[0017] Furthermore, two ventilation openings are provided through the bottom of the enclosure, and two fans are fixedly installed at the bottom of the enclosure, with the two fans corresponding to the two ventilation openings.

[0018] The above solution, through the installation of ventilation vents and fans, can cool the inside of the enclosure, preventing excessively high internal temperatures from affecting electrical components.

[0019] Furthermore, the installation device structure inside the box is the same.

[0020] Using the above method, different models of electricity meters can be successfully installed by setting up the same installation device.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Please see Figure 2 and Figure 3The three-phase meter box in this embodiment includes a box body 1. A fixing frame 6 is fixedly installed inside the box body 1. A first sliding groove 7 and a second sliding groove 8 are respectively opened through the two ends of the fixing frame 6. A first slider 9 and a second slider 10 are respectively slidably installed inside the first sliding groove 7 and the second sliding groove 8. A third sliding groove 11 is opened inside the second slider 10. The end of the first slider 9 away from the first sliding groove 7 passes through the third sliding groove 11.

[0030] Please see Figure 3 The upper ends of the fixed frame 6, the first slider 9 and the second slider 10 are all provided with multiple fastening threaded holes 14. One of the fastening threaded holes 14 is threaded with a fastening bolt 16. The second slider 10 is provided with multiple limiting threaded holes 15 on one side. A connecting block 12 is fixedly installed on the outer wall of the end of the first slider 9 that extends out of the third slide groove 11. A limiting bolt 13 passes through the connecting block 12. The end of the limiting bolt 13 passes through the connecting block 12 and is threadedly connected to the limiting threaded hole 15.

[0031] Please see Figure 1 The box body 1 is fixedly connected to a door 3 by two rotating hinges 2 on one side. A handle 4 is fixedly installed on one side of the door 3. The door 3 is used to seal the box body 1. The handle 4 makes it easy to operate the door 3. Four acrylic plates 5 are fixedly installed inside the door 3. The acrylic plates 5 are transparent. The four acrylic plates 5 correspond to four mounting devices, making it easy to see the electricity meter fixed on them.

[0032] Please see Figure 2 and Figure 4 A conduit 17 is fixedly installed inside the upper part of the box 1. Two branch conduits 18 are fixedly installed on the outer wall of the end of the conduit 17 that extends into the box 1. The conduit 17 and branch conduits 18 are used to store the wires and ensure that the wires are neat and beautiful. The outer wall of each branch conduit 18 is rotatably equipped with a sealing tube 19. Each sealing tube 19 has two outlet holes 20. The four outlet holes 20 correspond to four installation devices. The wires extending out of the outlet holes 20 are connected to each corresponding electricity meter. Fasteners 21 are fixedly installed inside the box 1. The fasteners 21 are nested with the conduit 17 that extends into the box 1 to fix the conduit 17.

[0033] Please see Figure 2 Two ventilation openings 22 are opened through the bottom of the box 1. Two fans 23 are fixedly installed at the bottom of the box 1. The two fans 23 correspond to the two ventilation openings 22. The ventilation openings 22 and the fans 23 can cool down the inside of the box 1 and prevent the internal temperature of the box 1 from being too high and affecting the electrical components. The installation device inside the box 1 has the same structure. When installing different models of electricity meters, the same installation device can be used to successfully install different models of electricity meters.

[0034] In this embodiment, by setting up a fixing frame 6, a first sliding groove 7, a second sliding groove 8, a first slider 9, a second slider 10, and a third sliding groove 11, if the meter's mounting holes are located at the top and bottom, the position of the fastening threaded holes 14 between the top and bottom can be adjusted by moving the second slider 10, facilitating the installation of the meter. If the meter's mounting holes are located on the left and right sides, the distance between the fastening threaded holes 14 between the left and right sides can be changed by moving the first slider 9, facilitating the installation of the meter. Through the above settings, the device can adjust the distance between the fastening threaded holes 14 between the top, bottom, left, and right sides according to the installation method of different meters, facilitating the installation of different models of meters. At the same time, through the set conduit 17 and other structures, the wires can be organized as a whole, making the inside of the box 1 neater.

[0035] It should be noted that the second slide groove 8 is opened inside the fixed frame 6, and the fastening threaded hole 14 opened inside it is a through threaded hole. Secondly, the first slider 9 is also opened inside the through threaded hole. After the position of the second slider 10 is adjusted by moving it up and down, the position of the second slider 10 is fixed by the fastening bolt 16. After the second slider 10 is moved, one end of it inside the second slide groove 8 will be at the lower end of the fastening threaded hole 14. After the fastening bolt 16 is threadedly connected to the fastening threaded hole 14, the bottom end of the fastening bolt 16 contacts the second slider 10, and the second slider 10 is limited by friction.

[0036] The working principle of the above embodiments is as follows:

[0037] When using this device, first open the box door 3 and observe the installation method of the meter. Adjust accordingly based on the installation method. If the meter's mounting holes are located at the top and bottom, adjust the position of the fastening threaded hole 14 between the top and bottom by moving the second slider 10. After the second slider 10 is moved, one end of it inside the second slide groove 8 will be at the lower end of the fastening threaded hole 14. After the fastening bolt 16 is threaded into the fastening threaded hole 14, the bottom end of the fastening bolt 16 contacts the second slider 10, and the second slider 10 is limited by friction. If the meter's mounting holes are on the left and right sides, change the distance between the fastening threaded holes 14 between the left and right sides by moving the first slider 9. The first slider 9 is moved by using the cooperation between the limiting bolt 13 and the limiting threaded hole 15. When connecting the meter, the wire is passed through the conduit 17 and the branch conduit 18, and finally pulled out from the corresponding outlet hole 20 to connect to the meter. The ventilation port 22 and the fan 23 are used to dissipate heat from the inside of the box 1 to ensure the temperature inside the box 1.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
