Description

Technical Field

[0001] The utility model relates to the field of civil air defense door processing, in particular to a door leaf frame welding platform. Background Art

[0002] Civil defense doors are the doors at the entrances and exits of people's defense projects. There are distinct classifications of civil defense doors, including ordinary single-leaf and double-leaf protective closed doors and closed doors, movable threshold single-leaf and double-leaf protective closed doors and closed doors, and other civil defense equipment. Civil defense doors are an activity for the government to mobilize and organize the masses, take anti-air raid, disaster resistance and relief measures, implement rescue operations, and prevent and reduce the hazards of disasters. The door frames of civil defense doors need to be welded during the manufacturing process.

[0003] After searching, the Chinese patent announcement number CN218695571U discloses a civil air defense door leaf frame welding platform. The patent uses a first threaded rod to push the clamps closer to each other, thereby clamping the door frame, which is convenient for clamping according to the size of the door frame, maintaining the overall stability of the door frame during welding, improving the accuracy of welding, and facilitating the operation of the staff. By pulling the L-shaped movable rod on the second limit rod and rotating the second threaded rod, the support rod is pushed to move, which is convenient for adjustment according to the length and width of the door frame. By rotating the third threaded rod, the third threaded rod squeezes the door frame downward to further maintain the stability of the door frame. The turning handle facilitates the rotation of the first threaded rod, the rubber sleeve improves the comfort of the staff's grip, the turning block facilitates the rotation of the second threaded rod and the third threaded rod, the buffer pad reduces the clamping damage of the clamp on the door frame while increasing the clamping friction and reducing shaking. The first limit rod limits the clamp to improve the stability of the clamp.

[0004] However, since the civil air defense door is large and heavy, it will produce greater friction with the welding platform during the welding process, making it inconvenient to move. Utility Model Content
