[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figures 1 to 5The utility model provides a technical solution: an electrical installation junction box for outdoor construction projects, comprising a junction box body 1 and a mounting plate 3, wherein limit columns 2 are installed on corresponding sides of the junction box body 1, a convex groove 4 is provided inside the mounting plate 3, two convex blocks 5 are slidably connected inside the convex groove 4, and positioning plates 6 are installed on the tops of the two convex blocks 5, and positioning grooves 7 are provided inside the positioning plates 6, and the positioning grooves 7 are plugged with the limit columns 2, and a bidirectional screw rod 8 is rotatably connected inside the convex groove 4, and the bidirectional screw rod 8 passes through the two convex blocks 5 and is threadedly connected with the two convex blocks 5, so that the two convex blocks 5 move with the rotation of the bidirectional screw rod 8, and the two positioning plates 6 are driven to move, so that the limit columns 2 can pass through while clamping the junction box body 1. The positioning groove 7 in the positioning plate 6 limits the junction box body 1, which is convenient for the installation and disassembly of the junction box body 1. A twist knob 9 is rotatably connected to one side of the junction box body 1, and the twist knob 9 is fixedly connected to the bidirectional screw rod 8. A threaded hole 12 is provided inside the limiting column 2, and a threaded column 13 is threadedly connected to the inner thread of the positioning plate 6. One end of the threaded column 13 is inserted into the threaded hole 12 and is threadedly connected to the threaded hole 12, so that the threaded column 13 is rotated and displaced at the same time, and one end thereof is inserted into the threaded hole 12 and connected, which is convenient for secondary fixing of the junction box body 1 and is not easy to loosen. A plurality of wiring terminals 10 are installed on one side of the junction box body 1, and a water-absorbing sponge pad 11 is pasted inside the plurality of wiring terminals 10, which wraps the cable while absorbing the infiltrated water and moisture. This is beneficial to improving the safety of the terminal 10. An air bag 14 is installed on the top of each of the plurality of terminals 10. An air inlet pipe 15 and an air outlet pipe 16 are connected to one end and the bottom of the air bag 14 respectively. One end of the air outlet pipe 16 extends into the terminal 10. A one-way valve is installed inside the air inlet pipe 15 and the air outlet pipe 16, so that the air bag 14 can introduce air from the air outlet pipe 16 into the terminal 10 through squeezing, and discharge dust and other substances attached to the terminal 10 to the outside, which is convenient for cleaning the terminal 10. Under the action of the air inlet pipe 15, the air bag 14 is automatically filled so that it can be reused. A dust cover 22 is installed at one end of the air inlet pipe 15 to intercept dust in the air and prevent it from entering the air bag 14 and the terminal 10. One side of the junction box body 1 and the position A support frame 17 is installed on the top of multiple terminals 10, and a slide groove 18 is opened inside the support frame 17. Two sliders 19 are slidably connected inside the slide groove 18. The tops of the two sliders 19 are connected with sealing plates 20. The sealing plates 20 fit the terminal 10. Two telescopic springs 21 are installed inside the slide groove 18. One end of the two telescopic springs 21 is respectively connected to the two sliders 19. Through the deformation of the telescopic springs 21, the two groups of sealing plates 20 can be displaced and automatically reset, and the terminal 10 is closed when not in use for dustproof sealing. A sealing gasket 23 is installed on one side of the sealing plate 20, which is beneficial to increase the sealing between the sealing plate 20 and the terminal 10. A magnetic metal sheet 24 is installed on the top of the mounting plate 3 and on one side of the convex groove 4.A magnet sheet 25 is installed at the bottom of the junction box body 1 and above the magnetic metal sheet 24. The magnet sheet 25 is adsorbed between the magnetic metal sheet 24 and the magnet sheet 25 to fix the junction box body 1 and the mounting plate 3 together, which is beneficial to further prevent the junction box body 1 from falling off.

[0024] In summary, when the electrical installation junction box for outdoor construction projects is used, after the mounting plate 3 is installed on the building, the junction box body 1 is placed on the mounting plate 3, and the knob 9 is turned to drive the bidirectional screw rod 8 in the mounting plate 3 to rotate. The two convex blocks 5 and the top positioning plate 6 thereof are displaced accordingly, and the limiting columns 2 on both sides of the junction box body 1 pass through the positioning grooves 7 in the two positioning plates 6 respectively to clamp and fix the junction box body 1, so as to rotate the threaded column 13 connected to the inner thread of the positioning plate 6, and one end of the threaded column 13 is displaced accordingly and inserted into the inner threaded column 13 of the limiting column 2, and the threaded connection between the threaded column 13 and the threaded hole 12 is used to fix the limiting column 2. Similarly, the threaded column 13 and the knob 9 are rotated in the opposite direction so that one end of the threaded column 13 and the limiting column 2 are respectively moved out of the threaded hole 12 and the positioning groove 7 can be pulled out, the clamping of the junction box body 1 is released, and the junction box body 1 can be removed. Since two groups of sealing plates 20 are arranged in front of the plurality of terminal blocks 10, and since the slider 19 at the bottom of the sealing plate 20 is slidably connected with the slide groove 18 in the support frame 17, under the action of the telescopic spring 21, the two groups of sealing plates 20 are slid, and the distance between the two sealing plates 20 can be pulled apart to open the terminal 10. At this time, the connector of the cable is inserted into the terminal block 10 for connection. At the same time, the absorbent sponge pad 11 in the terminal block 10 wraps the cable to block external moisture and water. After the cable is pulled out, the airbag 14 on the terminal block 10 can be squeezed according to needs, and the air in the airbag 14 is introduced into the terminal block 10 through the air outlet pipe 16, so that the dust and other substances attached to the terminal block 10 are discharged to the outside.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
