[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a multifunctional junction box for receiving signals from various flow meters, comprising a box body 1, an interface 2, a track groove 3, a locking bolt 4, a locking nut 5, a side hole 6, a retaining plate 7, a back plate 8, a mounting window 9, a base plate 10, a reinforcing plate 11, a track window 12, a threaded rod 13, a positioning nut 14, and a C-type clip 15. The interface 2 is installed in the middle of the outer side of the box body 1, and the track groove 3 is opened at the rear of the outer side of the box body 1. The inner wall of the track groove 3 is fitted to one end of the locking bolt 4, and the locking nut 5 is installed at the other end of the locking bolt 4. Locking bolt 4 passes through side hole 6, side hole 6 is opened on card plate 7, one side of card plate 7 is attached to the outer side of box body 1, back plate 8 is fixed to the rear end of card plate 7, front side of back plate 8 is attached to rear side of box body 1, installation window 9 is opened at the end of back plate 8, base plate 10 is fixed to the middle of outer side of box body 1, reinforcing plate 11 is installed at the connection between base plate 10 and outer side of box body 1, track window 12 is opened on base plate 10, threaded rod 13 is installed through track window 12, positioning nut 14 is installed on threaded rod 13, and C-type clip 15 is fixed at the end of threaded rod 13.

[0021] In this example, the locking bolt 4 and the track groove 3 are slidably connected. The top view cross-sectional shape of both the locking bolt 4 and the track groove 3 is "T" shaped. The above structural design ensures that the locking bolt 4 will not detach from the track groove 3, allowing the locking bolt 4 to be stably slidably adjusted and stably stationary along the track groove 3.

[0022] The card plate 7 is symmetrically distributed about the center of the back plate 8, and the back plate 8 has symmetrical installation windows 9 at both ends. The above structural design allows the card plate 7 and the back plate 8 to be stably installed on the back of the box body 1, ensuring that the box body 1 can be stably installed and fixed.

[0023] The reinforcing plates 11 are symmetrically distributed about the center of the substrate 10. The side view width of the reinforcing plates 11 is greater than 3 / 4 of the side view width of the substrate 10. The above structural design enables the reinforcing plates 11 to stably support and position the substrate 10.

[0024] The length of the track window 12 is greater than half the length of the base plate 10. Interfaces 2 are symmetrically arranged on the upper and lower sides of the base plate 10. The above structural design provides a stable mounting base for the threaded rod 13, allowing the threaded rod 13 and the C-type clip 15 to be aligned with the interface 2, and ensuring that the adjustment range of the threaded rod 13 is large enough.

[0025] The threaded rod 13 is slidably connected to the track window 12. Positioning nuts 14 and C-type clips 15 are symmetrically installed on both sides of the center of the threaded rod 13. The above structural design allows the threaded rod 13 to slide along the track window 12 with the C-type clips 15 to adjust the installation position, and to quickly fix the base plate 10 by pressing it with the symmetrically distributed positioning nuts 14.

[0026] Working principle: During installation, first adjust the working positions of the symmetrically distributed card plate 7 and back plate 8 according to the actual situation of the installation surface. Push the card plate 7 and back plate 8 to slide along the rear side of the box body 1. The card plate 7, with the locking bolt 4, slides steadily and vertically along the track groove 3. When the positions of the card plate 7 and back plate 8 are appropriate, rotate the locking nut 5 to press the card plate 7 into the side of the box body 1 and fix it. Use connecting parts to pass through the installation window 9 to connect and fix it to the installation surface, and install and fix the box body 1 as a whole.

[0027] Then, according to the design layout of the connection cable of the interface 2, the threaded rod 13 is moved to slide horizontally along the track window 12. The working position of the threaded rod 13 and the C-type card 15 is adjusted until the position of the C-type card 15 is appropriate. The symmetrically distributed positioning nuts 14 are rotated to press the upper and lower end faces of the base plate 10 to fix it. The cable is connected to the interface 2 and the cable is inserted into the C-type card 15. This is the working principle of the multi-functional junction box that receives signals from multiple flow meters.
