Referring to fig. 4A and 4B, a structure of the hinge frame 100 of the standing frame 10 is illustrated. The hinge frame 100 is formed by bending a sheet metal. Specifically, the hinge frame 100 sequentially includes a first inner rib 110, a first light-transmitting rib 120, a first positioning rib 130, a first mounting rib 140 and a first outer rib 150, the first inner rib 110, the first positioning rib 130 and the first outer rib 150 extend in a horizontal left-right direction, an extending direction of the first positioning rib 130 is opposite to an extending direction of the first inner rib 110, and an extending direction of the first outer rib 150 is the same as an extending direction of the first positioning rib 130; the first light-transmitting side 120 and the first mounting side 140 extend in the horizontal front-back direction, and the extending direction of the first light-transmitting side 120 is the same as that of the first mounting side 140.

Specifically, referring to fig. 4A, the first inner rib 110 extends in a horizontal leftward direction; then the end of the first inner rib 110 extends along the horizontal backward direction to form a first light-transmitting edge 120; then the end of the first light-transmitting side extends to the right along the horizontal direction to form a first positioning side 130; then the end of the first positioning edge 130 extends along the horizontal backward direction to form a first mounting edge 140; finally, the end of the first mounting edge 140 extends horizontally to the right to form a first outer rib 150.

In some embodiments, the first inner rib 110 may also extend along a horizontal direction, and accordingly, the first light-transmitting rib 120, the first positioning rib 130, the first mounting rib 140 and the first outer rib 150 may extend along the corresponding directions.

The ribs 12 are formed on the first inner rib 110 and the first outer rib 150 by bending. That is, the protruding ribs 12 are also formed by bending the same metal plate as the hinge frame 100, and the protruding ribs 12 are located at the front and rear ends of the hinge frame 100. Meanwhile, the latch 11 is disposed on the first light-transmitting edge 120 and the first mounting edge 140.

During production, the expanded plan view of the hinge frame 100 is determined according to the actual processing requirements. Generally, the dimensions of the first inner rib 110, the first light-transmitting rib 120 and the first outer rib 150 are determined according to the size of the door opening to be installed. The dimensions of the first positioning edge 130 and the first mounting edge 140 are fixed, wherein the first positioning edge 130 is a design inertia, and the first positioning edge 130 functions to provide a mounting position of the sealing strip and a stopping function when the door is closed; the size of the first mounting edge 140 corresponds to the thickness of the door leaf, and the size of the first mounting edge is fixed because the thickness of the door leaf is substantially fixed when the door is processed by a doorman. The size of the first transparent edge 120 can be adjusted adaptively according to the thickness of the actual door opening, and the sizes of the first inner rib 110 and the first outer rib 150 can be adjusted adaptively according to the width of the actual door opening. While the dimensions of the ribs 12 are generally constant.

After the unfolded plan view of the hinge frame 100 is determined, the next process can be performed according to the unfolded plan view. During processing, the data input of the expansion diagram is input into the laser cutting machine, then the metal plate is cut out through the laser cutting machine, and during cutting, the fixture block 11 can be cut out simultaneously. Meanwhile, creases are processed together by a laser cutting machine.

After laser cutting, in order to make the folding of the hinge frame 100 more convenient and the forming quality after folding better, the pit of the mark can be planed by using a horizontal pit planing machine. Utilize laser cutting can accurately process out the crease, then dig the hole of a V-arrangement in the surface of panel beating out by the machine of digging a hole, utilize numerical control bender at last, according to actual demand, the bending is out hinge frame 100. Because numerous V-shaped pits have been planed in advance on the sheet metal component, the precision is higher during bending, and the forming quality after bending is better.

Referring to fig. 7, the specific bending steps may be: the convex ribs 12 are bent outwards at two ends of the metal plate, the first mounting edge 140 is bent outwards at the middle part, the first positioning edge is bent inwards to form, and finally the first inner rib 110 and the first outer rib 150 are bent inwards at two ends respectively. After bending, the hinge frame 100 structure shown in fig. 4A is formed.

After the hinge frame 100 is bent and formed, two ends of the connecting seat 400 may be welded between the first inner flange 110 and the first outer flange 150, respectively, in a welding manner.

Referring to fig. 5A and 5B, there is shown a schematic structural view of the lock frame 200 of the stand frame 10. When in use, the hinge is arranged between the hinge frame 100 and the door leaf, and the lock seat is arranged in the lock frame 200. When the door is closed, the lock in the door leaf will lock with the lock seat in the lock frame 200. In order to ensure that the door leaf and the door frame have better sealing performance when the door is closed, a sealing step is arranged on the lock frame 200 and consists of a transverse sealing edge and a vertical sealing edge.

Specifically, the lock frame 200 sequentially includes a second inner rib 210, a second light-transmitting rib 220, a second positioning rib 230, a second mounting rib 240, a transverse sealing edge 250, a vertical sealing edge 260, and a second outer rib 270, the second inner rib 210, the second positioning rib 230, the transverse sealing edge 250, and the second outer rib 270 extend in a horizontal left-right direction, an extending direction of the second positioning rib 230 is opposite to an extending direction of the second inner rib 210, and the extending directions of the transverse sealing edge 250 and the second outer rib 270 are the same as the extending direction of the second positioning rib 230; the second light-transmitting edge 220, the second mounting edge 240 and the vertical sealing edge 260 extend in the front-back direction, and the extending directions of the second light-transmitting edge 220, the second mounting edge 240 and the vertical sealing edge 260 are the same.

Referring to fig. 5A, the second inner rib 210 extends in a horizontal rightward direction; then the end of the second inner rib 210 extends along the horizontal backward direction to form a second light-transmitting edge 220; then the end of the second light-transmitting side 220 extends along the horizontal left direction to form a second positioning side 230; then the end of the second positioning edge 230 extends along the horizontal backward direction to form a second mounting edge 240; then the end of the second mounting edge 240 extends along the horizontal left direction to form a transverse sealing edge 250; then the tail end of the transverse sealing edge 250 extends along the horizontal backward direction to form a vertical sealing edge 260; finally, the end of the vertical seal extends in the horizontal leftward direction to form a second outer lip 270.

And ribs 12 are formed on the second inner rib 210 and the second outer rib 270 by bending.

That is, the rib 12 is formed by bending the same metal plate as the lock frame 200. Meanwhile, the latch 11 is disposed on the second light-transmitting side 220 and the second mounting side 240.

The processing method of the lock frame 200 is the same as that of the hinge frame 100, and therefore, the detailed description thereof is omitted. It should be understood that the overall width of the formed lock frame 200 is the same as the overall width of the hinge frame 100, and the dimensions of the first light-transmitting rim 120 and the second light-transmitting rim 220 are the same, i.e., the dimension of the first mounting rim 140 is equal to the sum of the dimension of the second mounting rim 240 and the dimension of the vertical seal 260. After the door frame is installed, the distance between the first transparent edge 120 and the second transparent edge 220 is the light transmission size (or visible light size) of the door, and the distance between the first mounting edge 140 and the second mounting edge 240 is the width of the door leaf.

When the door frame is used, the sealing rubber strips can be added on the sealing steps and the positioning edges, so that the door frame and the door leaf are better in sealing performance.

Referring to fig. 6A and 6B, a schematic view of the structure of the horizontal frame 300 is shown. The cross section of the horizontal frame 300 is substantially the same as that of the hinge frame 100 due to the restriction requirements of the door opening and the door leaf. In contrast, the fixture block 11 does not need to be machined on the transverse frame 300, but the through groove 310 needs to be machined, and in order to align the end surfaces of the assembled door frame, a corresponding avoiding position needs to be cut on the transverse frame 300 during laser cutting. Since the horizontal frame 300 includes a downwardly protruding structure, the hinge frame 100 and the lock frame 200 need to be cut away from the escape space at the corresponding position (as can be seen from fig. 4B and 5B, the position of the first transparent edge 120 corresponding to the second transparent edge 220 is cut away).

The horizontal frame 300 is processed in the same manner as the hinge frame 100. And the same is formed by laser cutting, pit digging and numerical control bending. Similarly, the horizontal frame 300 may also be provided with a rib, and during installation, the horizontal frame 300 may also be clamped with a binding section bar. The two edge covering sections 600 of the vertical frame 10 and the edge covering section on the horizontal frame 300 jointly form a decorative edge of the door frame, and the edge covering sections on the horizontal frame 300 and the edge covering sections on the vertical frame 10 can be connected through corner connectors (not shown in the figure).

Further as a preferred embodiment, the edge-covering section bar 600 comprises a clamping groove 610, the protruding rib 12 is embedded in the clamping groove 610, and a glue layer is arranged between the clamping groove 610 and the protruding rib. The connection between the edge covering section bar 600 and the convex rib 12 can be more tight by using special metal glue. In addition, the width of the slot 610 is slightly larger than the thickness of the rib 12, so that the edge-covering section bar 600 can swing relatively, the packaging section bar 600 is leveled, and the defect that the wall body is not straight is overcome. After leveling, the binding profile 600 is firmly mounted on the door frame by glue bonding.

In a further preferred embodiment, the fixture block 11 is provided with a screw hole. Or, the fixture block is provided with a through hole, and the bolt is in threaded connection with the bolt by using a nut after penetrating through the fixture block.

Further as a preferred embodiment, a reinforcing rib 160 is further disposed in the hinge frame 100, and two ends of the reinforcing rib 160 are respectively fixedly connected to the first inner rib 110 and the first outer rib 150; the first mounting edge 140 is provided with a mounting hole 141. The number of the reinforcing ribs 160 may be plural, and the plural reinforcing ribs 160 are distributed on the hinge frame 100 from top to bottom. Similarly, the lock frame 200 may also be provided with a corresponding rib structure.

Referring to fig. 3, the door frame may be integrally fixed after the complete vertical frame 10 and the horizontal frame 300 are assembled at a construction site. When fixing, the door frame can be fixed on the wall of the door opening by first using expansion bolts to pass through the mounting holes 141. Because on the hinge frame, a back cavity is formed among the first inner flange, the first mounting edge and the first outer flange (in the same way, the back cavity is also formed on the lock frame), and then cement paste is filled between the door opening and the back cavity. When the cement paste dries out and is condensed, the door frame is firmly combined with the wall body.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
