Technical Field

[0001] The utility model relates to the technical field of fire doors, in particular to a fire door with an auxiliary installation structure. Background Art

[0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. Fire doors are usually used in places with high traffic, such as large shopping malls, office buildings, schools, supermarkets, railway stations, bus stations, etc., and they have made great contributions to the fire safety of existing society.

[0003] According to a publicly disclosed fire door structure that is easy to install (Announcement No.: CN212507983U), in the above application, by setting a bolt slot, during installation, it is only necessary to insert the bolt on the fire door panel into the bolt slot, take out the limit rod in the limit slot, slide the support rod to the left to make the auxiliary support rod fall, push the support rod to the right, insert the limit rod installation cover plate to complete the installation.

[0004] However, during the actual use of the above-mentioned equipment, the door body and door frame of the fire door need to be connected by aligning the hinges between the two. However, since fire doors are generally heavy, lifting the fire door and aligning the hinges at the same time not only reduces the installation efficiency of the fire door, but also poses certain safety hazards. In view of this, we propose a fire door with an auxiliary installation structure. Utility Model Content

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a fire door with an auxiliary installation structure, including a door body 1, a connecting component 2 is provided on the side of the door body 1, and the connecting component 2 includes a sliding groove 21, a T-shaped groove 22, a T-shaped slider 23, a connecting seat 24, a square groove 25, a locking bolt 28, a square plate 27, an insertion rod 26, a docking groove 29, a docking shaft 210, a connecting piece 211 and a connecting bolt 212.

[0024] In one embodiment of the present utility model, a sliding groove 21 is provided on the side wall of the door body 1, and a T-shaped groove 22 is provided on the inner wall of the sliding groove 21 close to the center of the door body 1. A T-shaped slider 23 is slidably installed inside the T-shaped groove 22, and a connecting seat 24 is fixedly installed on the side wall of the T-shaped slider 23. A square groove 25 is provided on the outer wall of the connecting seat 24 away from the center of the door body 1. A square plate 27 is detachably installed inside the square groove 25 through a locking bolt 28, and an insertion rod 26 is fixedly installed on the side wall of the square plate 27. A docking groove 29 is provided on the inner wall of the connecting seat 24, and a docking shaft 210 is movably installed inside the docking groove 29. A connecting piece 211 is fixedly installed on the bottom end of the docking shaft 210, and a connecting bolt 212 is threadedly connected to the inner wall of the connecting piece 211.

[0025] Furthermore, there are two groups of connecting components 2, and the two groups of connecting components 2 are distributed in a linear array on the same side of the door body 1, so that the connecting components 2 can assist the door body 1 in installation. At the same time, the T-shaped slider 23 is adapted to the T-shaped slot 22, thereby guiding the movement of the connecting seat 24. In addition, a socket adapted to the insertion rod 26 is provided on the inner wall of the sliding slot 21, and another group of sockets is provided on the inner wall of the square slot 25, and a threaded hole adapted to the locking bolt 28 is provided on the inner wall of the square slot, so that the connecting seat 24 can be slid into place. When it moves to the bottom of the sliding groove 21, align the square plate 27 with the square groove 25, and finally insert the insertion rod 26 into the socket, and then tighten the locking bolt 28 to fix the square plate 27 inside the square groove 25. Specifically, there are four groups of insertion rods 26, and the four groups of insertion rods 26 are arranged in a rectangular array on the side wall of the square plate 27, so that when the insertion rod 26 is inserted into the socket, it can ensure that the connection seat 24, the square plate 27 and the door body 1 maintain a high stability, thereby ensuring the stable and safe use of the door body 1 during installation.

[0026] In addition, the docking groove 29 includes a cylindrical section and a conical section. The conical section is arranged at the bottom end of the cylindrical section, so as to facilitate the insertion of the docking shaft 210. At the same time, the top surface edge of the docking shaft 210 is rounded to ensure that the docking shaft 210 can more easily enter the docking groove 29. At the same time, the connecting member 211 is arranged in an L-shape, thereby providing sufficient space for the docking of the connecting member 211 and the connecting seat 24, thereby avoiding the connecting member 211 from interfering with the opening and closing of the door body 1. Furthermore, the number of connecting bolts 212 is set to four groups, and the four groups of connecting bolts 212 are arranged in a rectangular array on the inner wall of the connecting member 211 to facilitate the installation of the connecting member 211 and ensure the normal use of the fire door.

[0027] In an embodiment of the present utility model, a lubrication assembly 3 is provided inside the connecting seat 24, and the lubrication assembly 3 includes an oil storage chamber 31, which is opened on the top inner wall of the connecting seat 24, and a sealing plug 32 is detachably connected to the top of the oil storage chamber 31. A guide groove 33 is opened between the bottom of the oil storage chamber 31 and the docking groove 29, a square opening 34 is opened on the arc-shaped outer wall of the docking shaft 210, and a spiral groove 35 is opened on the arc-shaped outer wall of the docking shaft 210, and a plurality of protrusions 37 are fixedly installed on the inner wall of the spiral groove 35.

[0028] Specifically, the interior of the oil storage chamber 31 is filled with lubricating oil, and the lubricating oil can be replenished through the sealing plug 32. At the same time, the oil storage chamber 31 is opened near the top of the docking groove 29 to facilitate the lubricating oil to lubricate the surface of the docking shaft 210 from top to bottom under the action of gravity. In addition, the bottom end of the guide groove 33 is aligned with the square opening 34, so that under the action of gravity, the lubricating oil flowing out of the guide groove 33 can directly flow into the square opening 34. Specifically, the square opening 34 is initially arranged on the side away from the guide groove 33. When the door body 1 is opened, the connecting seat 24 and the docking shaft 210 rotate relative to each other until the guide groove 33 and the square opening 34 are close to and aligned with each other, the lubricating oil in the guide groove 33 flows out into the square opening 34 and continues to flow downward along the spiral groove 35, and then contacts the inner wall of the docking groove 29 to improve the rotation environment of the docking shaft 210 and ensure the normal opening and closing of the door body 1.

[0029] In the present invention, when in use, the user carries the door body 1 to the door frame and stands the door body 1 upright, then takes out the square plate 27 and pushes the connecting seat 24 upward, finally aligning the docking groove 29 with the top of the docking shaft 210, then lowers the connecting seat 24 and moves it down along the T-shaped slider 23 until it reaches the bottom of the sliding groove 21. At this time, align the insertion rod 26 on the square plate 27 with the insertion hole, tighten the locking bolt 28 after the square plate 27 is kept flush with the outer wall of the connecting seat 24 to complete the docking installation of the door body 1, reduce manpower consumption, improve the accuracy of the docking installation, and thereby improve the installation efficiency of the fire door.

[0030] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
