Technical Field
[0001] This utility model belongs to the field of door application technology, specifically relating to a large-angle opening free door. Background Technology
[0002] Current door designs typically only allow for opening / closing from 0 to 90 degrees after assembly, which limits their applications.
[0003] Currently, in places like hospitals where high passage efficiency is required, existing door designs with a 0-90° opening angle cannot meet the needs. These designs occupy passage space when opened, hindering passage and reducing efficiency. Therefore, designing a door structure capable of opening and closing at a large angle is a current research and development challenge.
[0004] Therefore, based on the above problems, this utility model provides a large-angle opening free door. Utility Model Content

[0021] Example
[0022] like Figure 1 and Figure 2 The large-angle opening free door shown includes a door body 10, an upper door frame 11, and a lower door frame 14.
[0023] A lower mounting groove 12 and an upper mounting groove 13 are provided on the same side of the door body 10.
[0024] The lower mounting slot 12 and the upper mounting slot 13 are respectively provided with a lower support rotating assembly 200 and an upper support rotating assembly 100;
[0025] Among them, such as Figure 6 The gate 10 shown uses the lower support rotating component 200 and the upper support rotating component 100 as support points, and rotates horizontally 150° to the left and right around the upper door frame 11 and the lower door frame 14, respectively, to achieve a bidirectional 300° rotation of the gate 10 and improve passage efficiency.
[0026] In addition, the upper support rotation assembly 100 preferably includes a U-shaped seat 101 installed in the upper mounting groove 13 by a first screw 102, a pad 104 disposed in one end of the U-shaped seat 101, a circular groove 103 disposed in one end face of the pad 104, a plate-shaped seat 107 installed in one end of the upper door frame 11 by a first screw 108, a transition reinforcing plate 105 installed on the plate-shaped seat 107 by a screw 106, a circular through groove 109 disposed in one end of the transition reinforcing plate 105, and a circular support sleeve 112 with one end located in the upper door frame 11 and the other end passing through the circular through groove 109 and located in the circular groove 103;
[0027] After installation, the circular support sleeve 112 supports the upper door frame 11 and rotates with the circular groove 103 as the limiting support. The transition reinforcement plate 105 rotates synchronously with the door body 10, the upper door frame 11, the plate-shaped seat 107, and the circular support sleeve 112.
[0028] In addition, the upper support rotating assembly 100 also includes a screw hole 110 disposed in the other end of the transition reinforcing plate 105, a stud 111 disposed on the plate-shaped seat 107 and fixed to the transition reinforcing plate 105 through the screw hole 110, a circular support portion 115 disposed at one end of the stud 111, a transverse transition support plate 113 disposed on one side of the plate-shaped seat 107, and an arc-shaped groove 114 disposed in one end of the transverse transition support plate 113 and matching the circular support portion 115.
[0029] After assembly, the circular support part 115 at one end of the stud 111 is located in the arc-shaped slot 114. In this way, the horizontal transition support plate 113 plays the role of vertically supporting the upper door frame 11, reducing the pressure on the circular support sleeve 112 and extending the service life of the circular support sleeve 112.
[0030] like Figure 3 , Figure 4 and Figure 5The lower support rotation assembly 200 shown includes a rectangular support portion 201, a first perforated ear plate 202 and a second perforated ear plate 204 respectively disposed on the rectangular support portion 201, a third screw 203 and a fourth screw 205 that install the rectangular support portion 201 in the lower mounting groove 12 through the first perforated ear plate 202 and the second perforated ear plate 204, a rotation support protrusion 210 disposed on the bottom surface of one end of the rectangular support portion 201, a support base 206 fixedly mounted on one end of the lower door frame 14, a rotation support portion 208 disposed in the support base 206, and a rotation support groove 209 disposed in the rotation support portion 208 and matching the rotation support protrusion 210.
[0031] After installation, the rotating support protrusion 210 is inserted into the rotating support groove 209, and the rotating support groove 209 serves as a limiting support, rotating synchronously with the door body 10, the lower door frame 14, and the rectangular support part 201.
[0032] In addition, the preferred lower support rotation assembly 200 also includes support base fixing ear plates 207 disposed on the outer walls of the four corners of the support base 206, and the support base 206 is fixed to the lower door frame 14 by screws through the support base fixing ear plates 207. Figure 2 , Figure 3 The screws are not marked, which does not affect the disclosure of the technical solution of this application.
[0033] This structure features a large-angle opening free door. By assembling the lower support rotating component 200 and the upper support rotating component 100 with the door body 10, the upper door frame 11, and the lower door frame 14, it solves the problem that traditional doors can only rotate from 0 to 90 degrees, and achieves bidirectional rotation from 0 to 300 degrees, greatly improving passage efficiency.
