DETAILED DESCRIPTION

[0030] The following is combined with Figures 1 to 4 This application is described in further detail.

[0031] An embodiment of the present application discloses a welding positioning device for a civil air defense door.

[0032] Reference Figure 1 A welding positioning device for a civil air defense door comprises a plate body 1, a mounting plate 2 is arranged above the plate body 1, a resistance plate 3 is fixed to one end of the mounting plate 2, the resistance plate 3 is L-shaped, and two symmetrically arranged support plates 9 are fixed to one end of the mounting plate 2 away from the resistance plate 3, an adjustment component is arranged between the mounting plate 2 and the plate body 1, and an adjustment mechanism is arranged between the support plate 9 and the resistance plate 3.

[0033] When the positioning device is in use, the staff will place the civil defense panel to be welded on the mounting plate 2, which will contact the contact plate 3. After placement, the civil defense doors of different sizes will be fixed through the adjusting mechanism, and then the panel to be welded will be placed on the civil defense panel, and the civil defense panel will be welded. The adjusting mechanism is convenient for the staff to fix the civil defense panels of different sizes, thereby reducing the impact on the welding of the civil defense panels.

[0034] Reference Figure 1 and Figure 2 The adjustment mechanism includes a fixed block 2 5 fixed on one side of the mounting plate 2, a bidirectional screw 8 is rotatably connected to the fixed block 2 5, the bidirectional screw 8 penetrates the fixed block 2 5, two symmetrically arranged fixed plates 6 are threadedly connected to the bidirectional screw 8, the fixed plate 6 and the mounting plate 2 are slidably arranged, a handle 14 is fixed to one end of the bidirectional screw 8, and a guide assembly is arranged at one end of the fixed plate 6 away from the bidirectional screw 8. The guide assembly includes a fixed block 14 fixed to the mounting plate 2, a guide rod 7 is fixed to the fixed block 14, the guide rod 7 slides through the fixed plate 6, and a fixing member is arranged on the fixed plate 6. The fixing member includes an adjustment column 10 rotatably connected to the upper end of the fixed plate 6, an adjustment plate 11 is fixed to the upper end of the adjustment column 10, a fixed screw 12 is threadedly connected to the adjusting plate 11, and a handle 19 is fixed to the upper end of the fixed screw 12. A round block 13 is fixed to the lower end of the fixed screw 12, and the lower end surface of the round block 13 is a rough metal surface.

[0035] When welding the civil air defense door, first check whether it is necessary to adjust the spacing of the fixing plate 6 according to the size of the civil air defense door, then place the civil air defense plate on the mounting plate 2, and then turn the handle 14 to drive the bidirectional screw 8 to rotate. The rotation of the bidirectional screw 8 drives the fixing plate 6 to move on the mounting plate 2. The fixing plate 6 moves relatively to fix the civil air defense door. When the fixing plate 6 moves, it slides on the guide rod 7 to limit the fixing plate 6, and then rotate the adjusting column 10 so that the fixing screw 12 is located above the mounting plate 2, and then turn the handle 2 19 to drive the fixing screw 12 to rotate. The fixing screw 12 moves on the adjusting plate 11, and drives the round block 13 to move downward to fix the plate surface to be welded. When there is a conflict, the rough surface of the round block 13 increases the friction, making the fixation more stable, which is convenient for the staff to fix civil air defense plates of different sizes and reduces the impact on the welding of civil air defense plates.

[0036] Reference Figure 1 and Figure 3 The adjustment assembly includes an electric multi-stage telescopic rod 17 fixed on the plate body 1, the upper end of the electric multi-stage telescopic rod 17 is fixedly connected to the mounting plate 2, and both ends of the plate body 1 are fixed with a sleeve plate 15. A sliding plate 16 is slidably connected in the sleeve plate 15, and the upper end of the sliding plate 16 is fixedly connected to the mounting plate 2.

[0037] When welding the civil air defense door, the height of the mounting plate 2 can be adjusted according to the height habits of the staff. During adjustment, the electric multi-stage telescopic rod 17 is started to drive the mounting plate 2 to rise and fall, and drive the sliding plate 16 to slide in the sleeve, so that the mounting plate 2 rises steadily and stops when adjusted to the appropriate position, which is convenient for the staff to adjust the height of the mounting plate 2 according to different heights and habits.

[0038] Reference Figure 4 A rotating column 18 is arranged between the two supporting plates 9 and distributed in an array, and the rotating column 18 is rotatably connected to the supporting plates 9.

[0039] When welding the civil air defense door, when the civil air defense door is placed on the mounting plate 2, the civil air defense door contacts the rotating column 18, so that the civil air defense door moves on the rotating column 18 to a suitable position, which is convenient for the staff to carry.

[0040] The implementation principle of the welding positioning device for a civil air defense door in this embodiment is as follows: when the positioning device is used, the staff puts the civil air defense plate to be welded on the mounting plate 2, and when preventing entry, the civil air defense door abuts against the rotating column 18, so that the civil air defense door moves on the rotating column 18, passes through the fixed plate 6 and abuts against the abutting plate 3;

[0041] Then, according to the size of the civil air defense door, see whether it is necessary to adjust the spacing of the fixing plate 6, and then put the civil air defense plate on the mounting plate 2, and then turn the handle 14 to drive the bidirectional screw 8 to rotate, and the rotation of the bidirectional screw 8 drives the fixing plate 6 to move on the mounting plate 2, and the fixing plate 6 moves relatively to fix the civil air defense door. When the fixing plate 6 moves, it slides on the guide rod 7 to limit the fixing plate 6, and then rotate the adjusting column 10 so that the fixing screw 12 is located above the mounting plate 2, and then turn the handle 2 19 to drive the fixing screw 12 to rotate, and the fixing screw 12 moves on the adjusting plate 11, and drives the round block 13 to move downward to fix the plate surface to be welded. When it conflicts, the rough surface of the round block 13 increases the friction, making the fixation more stable.

[0042] Then, the height of the mounting plate 2 can be adjusted according to the height habits of the staff. During adjustment, start the electric multi-stage telescopic rod 17 to drive the mounting plate 2 to rise and fall, and drive the sliding plate 16 to slide in the sleeve, so that the mounting plate 2 rises steadily and stops when adjusted to the appropriate position. After welding is completed, the bidirectional screw 8 and the fixed screw 12 can be loosened, the civil defense plate can be turned over and fixed, and then welding is performed. After completion, the civil defense plate can be removed.
