[0002] Metal doors are doors made of metal materials, such as aluminum alloy, stainless steel, iron, and copper. Nowadays, metal doors are widely used in various places due to their sturdiness, durability, and good anti-theft performance.

[0003] However, existing technologies have some problems: existing metal doors are usually customized according to the size of the holes pre-drilled in the wall by the user and then transported to the user's home for installation. However, during installation, the metal door usually does not perfectly match the size of the pre-drilled holes in the wall, requiring the addition of filler between the wall and the metal door. At the same time, the entire metal door needs to be fixed to the wall together with expansion screws during installation. The metal door is large and heavy, making it difficult to match the metal door with the pre-drilled holes in the wall, requiring repeated adjustments and making installation difficult. Therefore, we propose a metal door that is easy to install. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model separates a metal door into an outer door frame and an inner door frame. The position of the fixing plate is adjusted by the adjustment component on the outer door frame so that the size of the metal door matches the reserved size for the wall. Then, the inner door frame and the door panel are installed on the outer door frame by the positioning component and connecting screws. No filler is required, and the installation can be completed by only aligning the outer door frame. The installation is quick and convenient.

[0015] 2. This utility model is equipped with an adjustment component. When installing a metal door, first align the outer door frame with the reserved installation location, and then rotate the adjustment knob to make the adjustment cylinder slide in the groove of the outer door frame, thereby driving the fixing plate to open outward. Adjust the fixing plates on the left, right and top sides of the outer door frame in sequence, so that the fixing plates completely support the outer door frame at the installation location on the wall, so that the size of the metal door matches the reserved size of the wall. At the same time, the outer door frame is initially fixed by the fixing plate, and no calibration is required when further fixing it with expansion screws, which is convenient for installation.

[0016] 3. This utility model is equipped with a positioning component. After the outer door frame is fixed to the wall, the positioning block on the inner door frame is aligned with the hole on the connecting frame and pressed inward. This causes the locking block on the positioning block to compress the spring and move into the groove. When the locking block moves to the slot of the connecting frame, the locking block will move into the slot due to the spring's rebound force, thus locking the locking block into the slot. This initially fixes the inner door frame to the connecting frame, eliminating the need for adjustment when fixing with connecting screws later, making installation faster.

[0027] Furthermore, edge banding strips 11 can be detachably connected to both sides of the outer door frame 1. The edge banding strips 11 are made of stainless steel. The main function of the edge banding strips 11 is to cover the edge of the door panel 7 to prevent it from being worn and scratched during use. This not only extends the service life of the door but also maintains the good appearance of the door.

[0028] Furthermore, a fixing plate 2 is movably connected to the outer door frame 1, and an adjustment component 3 is provided on the outer door frame 1. The adjustment component 3 is used to adjust the position of the fixing plate 2. There are three sets of fixing plates 2 and adjustment components 3, which are respectively set on the left and right sides and the top of the outer door frame 1.

[0029] Specifically, the adjustment assembly 3 includes an adjustment knob 301, a slide groove is provided in the outer door frame 1, the adjustment knob 301 is rotatably connected in the slide groove, an adjustment cylinder 302 is fixedly connected in the middle of the fixing plate 2, the adjustment cylinder 302 is slidably connected in the slide groove, a threaded hole is provided on one side of the adjustment cylinder 302, and the adjustment knob 301 is threadedly connected in the threaded hole.

[0030] Furthermore, the adjustment assembly 3 also includes a guide rod 303, which is fixedly connected to the fixed plate 2. A guide groove is provided on the outer door frame 1, and the guide rod 303 is slidably connected in the guide groove. The guide rod 303 is used to support the fixed plate 2.

[0031] Furthermore, mounting holes are provided on the fixing plate 2, and clearance holes are provided on the outer door frame 1, with the mounting holes corresponding to the clearance holes.

[0032] Specifically, after the fixing plate 2 supports the outer door frame 1, use an electric drill to drill holes in the mounting holes of the fixing plate 2 through the clearance holes. Then, fix the fixing plate 2 and the outer door frame 1 to the wall with expansion screws.

[0033] Furthermore, a connecting frame 4 is fixedly connected to the outer door frame 1, and an inner door frame 5 is detachably connected to the connecting frame 4. A positioning component 6 is provided on the inner door frame 5, and a door panel 7 is rotatably connected to the inner door frame 5. The door panel 7 is rotatably connected to the inner door frame 5 via a hinge.

[0034] Specifically, the positioning component 6 includes a positioning block 601, which is fixedly connected to the inner door frame 5. A hole is provided on the connecting frame 4, and the positioning block 601 is slidably connected in the hole.

[0035] Furthermore, grooves are provided on both sides of the positioning block 601, and a locking block 602 is slidably connected in the groove. A spring 603 is fixedly connected to the locking block 602 and fixedly connected to the inner wall of the groove. A slot is provided on the inner wall of the hole of the connecting frame 4, and the locking block 602 is engaged in the slot.

[0036] Specifically, after fixing the outer door frame 1 to the wall, align the positioning block 601 on the inner door frame 5 with the hole on the connecting frame 4 and press it inward so that the locking block 602 on the positioning block 601 is compressed by the spring 603 and moves into the groove. When the locking block 602 moves to the slot of the connecting frame 4, the locking block 602 will move into the slot due to the rebound force of the spring 603, thereby locking the locking block 602 into the slot, thus initially fixing the inner door frame 5 to the connecting frame 4.

[0037] Furthermore, a rack 604 is fixedly connected to one end of the locking block 602, and a rotating groove is formed in the middle of the positioning block 601. A knob 605 is rotatably connected in the rotating groove, and a gear 606 is fixedly connected to one end of the knob 605. The gear 606 meshes with the rack 604.

[0038] Specifically, when disassembling the inner door frame 5, turn the knob 605. After the knob 605 turns, it drives the gear 606 to turn, which causes the locking blocks 602 on both sides of the positioning block 601 to compress the spring 603 and move into the groove, thereby causing the locking blocks 602 to disengage from the slot of the connecting frame 4. At this time, the inner door frame 5 can be removed.

[0039] Furthermore, a handle 8 is fixedly connected to the outer wall of the door panel 7, and a lock hole 9 is provided at the upper end of the handle 8 on the outer wall of the door panel 7. The metal door also includes a connecting screw 10. A threaded groove is provided on the connecting frame 4, and a through hole is provided on the inner door frame 5. The through hole corresponds to the threaded groove, and the connecting screw 10 passes through the through hole and is threadedly connected in the threaded groove.

[0040] Specifically, after the inner door frame 5 is initially fixed by the positioning component 6, the inner door frame 5 is further fixed by the connecting thread 10 to complete the installation of the metal door.

[0041] The working principle of this utility model is as follows:

[0042] This utility model separates a metal door into an outer door frame 1 and an inner door frame 5. The position of the fixing plate 2 is adjusted by the adjusting component 3 on the outer door frame 1 so that the size of the metal door matches the reserved size of the user's wall. Then, the inner door frame 5 and the door panel 7 are installed on the outer door frame 1 by the positioning component 6 and connecting screws. No filler is required, and the installation can be completed by only aligning the outer door frame 1. The installation is quick and convenient.

[0043] This utility model is equipped with an adjustment component 3. When installing a metal door, the outer door frame 1 is first aligned with the reserved installation location. Then, by rotating the adjustment knob 301, the adjustment cylinder 302 slides in the groove of the outer door frame 1, thereby driving the fixing plate 2 to open outward. The fixing plates 2 on the left, right and top sides of the outer door frame 1 are adjusted in sequence so that the fixing plates 2 completely support the outer door frame 1 at the installation location on the wall, so that the size of the metal door matches the reserved size of the wall. At the same time, the outer door frame 1 is initially fixed by the fixing plates 2. When further fixing it with expansion screws, no adjustment is required, which facilitates installation.

[0044] This utility model is equipped with a positioning component 6. After the outer door frame 1 is fixed to the wall, the positioning block 601 on the inner door frame 5 is aligned with the hole on the connecting frame 4 and pressed inward. This causes the locking block 602 on the positioning block 601 to compress the spring 603 and move into the groove. When the locking block 602 moves to the slot of the connecting frame 4, the locking block 602 will move into the slot due to the rebound force of the spring 603, thereby locking the locking block 602 into the slot. This initially fixes the inner door frame 5 to the connecting frame 4, so that no adjustment is needed when fixing it with the connecting screws 10, making the installation faster.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
