[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Specific examples are given below.

[0026] See also Figure 1-Figure 5The utility model provides a fixing bracket for electromagnetic environment monitoring equipment, comprising a fixing block 1: a supporting rod 2 is fixed to the top of the fixing block 1; a mounting bracket 3 is fixed to the top of the supporting rod 2; the top of the outer side of the fixing block 1 is rotatably connected to a plurality of connecting rods 5; the inner side of the end of the connecting rod 5 away from the fixing block 1 is slidably connected to a moving rod 6; a limiting assembly is provided on the inner side of the end of the connecting rod 5 away from the fixing block 1; the end of the moving rod 6 away from the connecting rod 5 is rotatably connected to a contact plate 7; the lower end of the fixing block 1 is fixed to a fixing rod 4; the lower end of the fixing rod 4 is fixed to an anti-falling block 9; the outer side of the fixing rod 4 is slidably connected to a sliding block 8; the outer side of the sliding block 8 is rotatably connected to a plurality of positioning rods 12; the end of the positioning rod 12 away from the sliding block 8 is rotatably connected to the connecting rod 5; a positioning assembly is provided on the inner side of the sliding block 8. When the device needs to be unfolded during operation, the limit of the sliding block 8 and the fixed rod 4 is first cancelled through the positioning assembly, so that the sliding block 8 can slide along the axial direction of the fixed rod 4, and then the multiple connecting rods 5 are unfolded respectively. When the connecting rod 5 is unfolded, the sliding block 8 is driven to slide along the axial direction of the fixed rod 4 through the positioning rod 12. When the connecting rod 5 is adjusted to a more stable angle, the sliding block 8 and the fixed rod 4 are fixed by the positioning assembly, so that the sliding block 8 cannot slide, so that the connecting rod 5 can be fixed by the positioning rod 12. Then, the limit of the mobile rod 6 is cancelled by the limiting assembly, so that the mobile rod 6 can slide out from the inside of the connecting rod 5, thereby adjusting the height of the fixed block 1 and the ground through the mobile rod 6. After the adjustment is completed, the mobile rod 6 is fixed by the limiting assembly After the connecting rod 5 is unfolded, the sliding block 8 can be slid along the axial direction of the fixed rod 4. When the angle of the connecting rod 5 is adjusted to a relatively stable state, the sliding block 8 and the fixed rod 4 can be fixed by the positioning assembly. After the sliding block 8 is fixed, the connecting rod 5 can be positioned by the positioning rod 12, so that the connecting rod 5 cannot rotate, and the device can be quickly and effectively unfolded. At the same time, the stability of the device can be effectively improved after unfolding.

[0027] Further, such as Figure 3As shown, the positioning assembly includes a driving screw 13; the driving screw 13 is arranged on the inner side of the sliding block 8; the driving screw 13 is rotatably connected to the sliding block 8; the end of the driving screw 13 close to the fixed rod 4 is threadedly connected with an internal threaded bolt 15; the internal threaded bolt 15 is slidably connected to the sliding block 8; a plurality of positioning holes 10 are evenly opened at positions of the fixed rod 4 corresponding to the internal threaded bolts 15; the internal threaded bolts 15 are plugged into the fixed rod 4 through the positioning holes 10. During operation, when the driving screw 13 rotates, it can drive the internal threaded bolts 15 threadedly connected to it to move along the axial direction of the driving screw 13. When the internal threaded bolts 15 move to the inside of the positioning holes 10, the connection between the sliding block 8 and the fixed rod 4 is completed, making the sliding block 8 unable to move. This step, through the structural design of the driving screw 13 and the internal threaded bolts 15, can limit the sliding block 8, thereby preventing the sliding block 8 from sliding and improving the stability of the sliding block 8.

[0028] Further, such as Figure 3 As shown, the end of the drive screw 13 away from the internal threaded bolt 15 extends to the outside of the sliding block 8; a positioning knob 14 is fixed to the end of the drive screw 13 located outside the sliding block 8. During operation, when the sliding block 8 needs to be fixed, the positioning knob 14 is first turned, so that the positioning knob 14 drives the drive screw 13 to rotate. This step improves the convenience of the operator due to the structural design of the positioning knob 14.

[0029] like Figure 3 As shown, anti-rotation blocks 16 are fixed on both sides of the end of the internal threaded bolt 15 close to the drive screw 13; the anti-rotation blocks 16 are slidably connected to the sliding block 8. During operation, when the drive screw 13 rotates, the anti-rotation blocks 16 can rotationally limit the internal threaded bolt 15, so that the internal threaded bolt 15 cannot rotate with the drive screw 13. Therefore, when the drive screw 13 rotates, it can drive the internal threaded bolt 15 to move along the axial direction of the drive screw 13. In this step, the anti-rotation blocks 16 can rotationally limit the internal threaded bolt 15, thereby preventing the internal threaded bolt 15 from rotating with the drive screw 13.

[0030] like Figure 5As shown, the limiting assembly includes a connecting plate 19; the connecting plate 19 is arranged on the inner side of the end of the mounting frame 3 away from the fixed block 1; the connecting plate 19 is slidably connected to the mounting frame 3; a plug bolt 18 is fixed on the side of the connecting plate 19 close to the moving rod 6; a plurality of limiting holes 11 are evenly opened at the positions corresponding to the moving rod 6 and the plug bolt 18; the plug bolt 18 is plugged and connected to the moving rod 6 through the limiting holes 11. When the lever 18 is moved out of the locking hole 11, the locking bolt 18 is released, and the locking bolt 18 is released to the left of the locking hole 11, thereby freeing the lever 18 from sliding movement.

[0031] like Figure 5 As shown, a connecting shaft 20 is fixed to the side of the connecting plate 19 away from the plug bolt 18; the connecting shaft 20 is slidably connected to the mounting frame 3; the end of the connecting shaft 20 away from the connecting plate 19 extends to the outside of the mounting frame 3; a lifting handle 22 is fixed to the end of the connecting shaft 20 located on the outside of the mounting frame 3; a spring 21 is sleeved on the outside of the end of the connecting shaft 20 close to the connecting plate 19; one end of the spring 21 is fixedly connected to the connecting plate 19; the other end of the spring 21 is fixedly connected to the mounting frame 3. During operation, when the length of the moving rod 6 needs to be adjusted, first pull the lifting handle 22 so that the lifting handle 22 drives the connecting plate 19 to move through the connecting shaft 20. When the adjustment is completed, release the lifting handle 22. At this time, the connecting plate 19 is pushed toward the moving rod 6 under the elastic action of the spring 21. This step can be achieved through the coordinated structural design of the connecting shaft 20, spring 21 and lifting handle 22, so that the connecting plate 19 can be driven to move. At the same time, the connecting plate 19 can be limited by the spring 21 to prevent the connecting plate 19 from sliding, thereby improving the stability of the connecting plate 19.

[0032] like Figure 4 As shown, an anti-drop plate 17 is fixed to one end of the moving rod 6 located inside the mounting frame 3; the anti-drop plate 17 is slidably connected to the mounting frame 3. This step can limit the moving rod 6 and prevent the moving rod 6 from moving out of the inner side of the mounting frame 3.

[0033] Working principle: When the device needs to be unfolded, the limit of the sliding block 8 and the fixed rod 4 is first canceled through the positioning assembly, so that the sliding block 8 can slide along the axial direction of the fixed rod 4, and then the multiple connecting rods 5 are unfolded respectively. When the connecting rods 5 are unfolded, the sliding block 8 is driven to slide along the axial direction of the fixed rod 4 through the positioning rod 12. When the connecting rods 5 are adjusted to a more stable angle, the sliding block 8 and the fixed rod 4 are fixed by the positioning assembly, so that the sliding block 8 cannot slide, so that the connecting rod 5 can be fixed by the positioning rod 12, and then the limit of the moving rod 6 is canceled by the limiting assembly. The movable rod 6 can slide out from the inside of the connecting rod 5, so that the height of the fixed block 1 and the ground can be adjusted by the movable rod 6. After the adjustment is completed, the movable rod 6 is fixed by the limit assembly, and then the device is placed on the ground so that the contact plate 7 is in contact with the ground. At the same time, the fixed block 1 can be kept vertical to the ground by adjusting multiple movable rods 6, so that the monitoring device can be installed on the top of the mounting bracket 3. When the sliding block 8 needs to be fixed, the positioning knob 14 is first turned so that the positioning knob 14 drives the driving screw 13 to rotate. When the driving screw 13 rotates, the anti-rotation block 16 can be used to prevent the screw from rotating inward. The threaded bolt 15 is set to a rotation limit so that the built-in threaded bolt 15 cannot rotate with the driving screw 13, so that when the driving screw 13 rotates, the built-in threaded bolt 15 can be driven to move along the axial direction of the driving screw 13. When the driving screw 13 rotates, it can drive the built-in threaded bolt 15 threadedly connected thereto to move along the axial direction of the driving screw 13. When the built-in threaded bolt 15 moves to the inside of the positioning hole 10, the connection between the sliding block 8 and the fixed rod 4 is completed, so that the sliding block 8 cannot move. When the length of the movable rod 6 needs to be adjusted, first pull the lifting handle 22 so that the lifting handle 22 passes The connecting shaft 20 drives the connecting plate 19 to move. When the adjustment is completed, the lifting handle 22 is released. At this time, the connecting plate 19 is pushed toward the direction close to the moving rod 6 under the elastic action of the spring 21. The movement of the connecting plate 19 can drive the plug bolt 18 to move at the same time. When the plug bolt 18 moves to disengage from the limiting hole 11, the plug bolt 18 cancels the limitation on the moving rod 6, so that the moving rod 6 can slide along the inner side of the mounting frame 3. After the adjustment is completed, the connecting plate 19 moves in the opposite direction, so that the plug bolt 18 moves to the inner side of the limiting hole 11, thereby completing the limitation of the moving rod 6.
