Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense doors, in particular to a hinge base positioning device for a steel structure movable door sill protecting a closed door frame. 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. The door frames and door leaves of civil defense doors are generally steel structures, and the door frames and door leaves are connected by hinges.

[0003] A door frame hinge generally includes a base welded to the door frame and a rotating shaft welded to the door leaf. When welding the hinge base to the door frame, it is necessary to draw a line on the door frame in advance to ensure that the welding position of the hinge base is accurate. However, since the current line drawing work is all manual, a tape measure is used to measure a specific length and draw a line. Then, the hinge base is placed at the drawn position for welding. During the welding process, the welding rod will poke into the hinge base, which can easily cause the hinge base to deflect, making it difficult for the hinge rotating shaft welded to the door leaf to accurately match the hinge base welded to the door frame.

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0023] Example 1

[0024] like Figure 1-6 As shown, the utility model provides a steel structure movable door sill protection closed door frame hinge base positioning device, including: two positioning components 1 and two support rods 2, the two positioning components 1 are installed on the door frame, respectively used to position the two hinge bases above and below the door frame, the two support rods 2 are installed at both ends of the two support rods 2, the positioning component 1 includes two clamping plates 11, and two L-shaped plates 12 are fixed between the two clamping plates 11. When the two clamping plates 11 are installed on the door frame, the two sides of the two L-shaped plates 12 are in contact with the two sides of the door frame respectively, and the other two L-shaped plates 12 are in contact with one side of the door frame. The L-shaped plates 12 are in contact with the door frame, which can play a role in positioning the clamping plates 11, so that the two clamping plates 11 1 is clamped at the designated position of the door frame, a clamping plate 15 is fixed on the top of the clamping plate 11, and a plurality of screws 16 are installed on the clamping plate 15. The clamping plate 15 and the screws 16 are used to position and fix the hinge base. A positioning plate 4 is fixed on the clamping plate 15, and part of the positioning plate 4 is in contact with the inside of the door frame. When in use, the hinge base is placed inside the clamping plate 15 so that the bottom of the hinge base is in close contact with the clamping plate 15. At the same time, one side of the hinge base is in contact with the positioning plate 4, and then the screw 16 is rotated so that the screw 16 is in contact with the hinge base, thereby tightly fixing the hinge base on the door frame. In this way, when the hinge base is welded, the hinge base will not deflect, thereby realizing the positioning of the hinge base and ensuring the accuracy of hinge welding.

[0025] Example 2

[0026] like Figure 3 As shown, two screw rods 13 pass through the two clamps 11, and nuts 14 are threadedly installed on the two screw rods 13. When the two clamps 11 are clamped on the door frame, the two clamps 11 are fixed by the two screw rods 13 and four nuts 14. At the same time, if the thickness of the door frame changes, the distance between the two clamps 11 can also be adjusted by the screw rods 13 and the nuts 14 so that both can adapt to door frames of different thicknesses.

[0027] Example 3

[0028] like Figure 5 As shown, a magnet 121 is installed on one side of the L-shaped plate 12, and the magnet 121 can attract the door frame. When the clamping plate 11 needs to be installed on the door frame, the L-shaped plate 12 is first placed in a suitable position so that the magnet 121 can attract the door frame. At this time, the clamping plate 11 is fixed on the door frame under the action of the magnet 121, which makes it easy to install the screw rod 13 and the nut 14.
