[0024] The structure of the present invention and the technical effects to be achieved will be described below with reference to specific embodiments and accompanying drawings. However, the selected embodiments are only used for illustration and explanation and are not intended to limit the scope of the present invention.

[0025] like Figure 1-Figure 5 As shown, the present invention provides a high-precision hanging hidden door system for building decoration wall, including a wall 1, the wall 1 having a door opening 11, a decorative panel 12 fixed to the outside of the wall 1, a door panel 2 fixed to the outside of the door opening 11, vertical keels 21 fixed to both sides of the back of the door panel 2, and vertical columns 13 fixed to both sides of the outer wall of the door opening 11. A hinge 3 is connected between the side of one keel 21 and the side of the corresponding column 13, so that the door panel 2 can rotate around the hinge 3 to open and close. In this embodiment, the cross-section of the column 13 is rectangular, and the cross-section of the keel 21 is U-shaped. An inwardly extending hanging tongue 22 is respectively provided on the inner side of the top of the two keels 21, and a vertical rack 23 is provided on the side of the hanging tongue 22. Specifically, the hanging tongue 22 is rectangular, and the inner end of the rack 23 has a smooth section 24. A load-bearing device 4 is provided on the outer wall of the door opening 11 at each position corresponding to the two hanging tongues 22.

[0026] like Figure 4 、 Figure 5 、 Figure 7 、 Figures 9-11As shown, the load-bearing device 4 includes a rectangular bottom plate 41, the four sides of which are, in a clockwise direction, a first side 411, a second side 412, a third side 413, and a fourth side 414. A rectangular fixing plate 42 extends upward from the first side 411 of the bottom plate 41, and a side plate 43 perpendicularly connected to the fixing plate 42 extends upward from each of the second side 412 and the fourth side 414. A locking plate 44 extends upward from the third side 413, and the locking plate 44 is provided with a rectangular notch 441 corresponding to the hanging tongue 22, allowing the hanging tongue 22 to enter the interior of the load-bearing device 4 along the rectangular notch 441. A baffle 45 is provided on the top of the fixing plate 42, side plates 43, and locking plate 44. A sleeve 415 with internal threads is fixedly mounted in the middle of the base plate 41. An externally threaded lifting rod 46 is mounted within this sleeve 415. A first gear 461 is fixedly mounted in the middle of the lifting rod 46. A rotatable end cap is mounted at the top of the lifting rod 46, the top of which is fixed to the bottom surface of a lifting plate 47. The lifting plate 47 is horizontal, with rectangular slides 471 mounted on either side, perpendicularly connected to the lifting plate 47. A vertical drive rod 48 is inserted through the lifting plate 47 at the edge of the rectangular notch 441. The bottom end of the drive rod 48 is rotatably connected to the base plate 41. A second gear 481 is fixedly mounted below the lifting plate 47, meshing with the first gear 461. A third gear 482 is fixedly mounted above the lifting plate 47, meshing with the rack 23 of the tongue 22. The top surface of the lifting plate 47 is provided with a plurality of rollers 472, each of which is fixedly connected to two slides 471 at both ends, and the top surface of each roller 472 corresponds to the bottom surface of the hanging tongue 22. The fixing plate 42 is fixed to the wall 1 via expansion bolts 421. The inner walls of the two side plates 43 are provided with T-shaped cross-sectional sliding grooves 431. Each slide 471 is located in a corresponding sliding groove 431 and can move up and down along the sliding groove 431. The side of the locking plate 44 opposite the keel 21 is fixed with a push-type rebounder 5, and the end of the rebound rod 51 of the push-type rebounder 5 is against the side of the keel 21.

[0027] In one embodiment, Figure 5 、 Figure 7 、 Figure 12As shown, the hinge 3 includes a first fixing member 31 and a second fixing member 32, which are connected by a first rotating plate 33, a second rotating plate 34, and a third rotating plate 35. The first fixing member 31 includes a first mounting plate 311, which has a first top plate 312 and a first bottom plate 313 at the top and bottom, respectively. A vertical first rotation axis 314 is provided between the first top plate 312 and the first bottom plate 313. The first mounting plate 311 is fixedly connected to the side of the column 13. The second fixing member 32 includes a second mounting plate 321, which has a second top plate 322 and a second bottom plate 323 at the top and bottom, respectively. A vertical second rotation axis 324 is provided between the second top plate 322 and the second bottom plate 323. The second mounting plate 321 is fixedly connected to the side of the keel 21. One side of the first rotating plate 33 is hinged to the first rotating shaft 314 , and the other side is hinged to the second rotating plate 34 via the third rotating shaft 36 . One side of the third rotating plate 35 is hinged to the second rotating shaft 324 , and the other side is hinged to the second rotating plate 34 via the fourth rotating shaft 37 .

[0028] In the present invention, the door panel hinge 3 and the load-bearing device 4 work together to open the door using a push-type rebounder 5. The push-type rebounder 5 is a common rebounder on the market, such as the push-type rebounder on the cabinet door. It is a finished hardware purchased from outside, and its structure will not be described in detail. When the door is closed, the weight of the door panel 2 mainly relies on the load-bearing device 4 and the hanging tongue 22 for hanging. The advantage is that the hanging installation is not easy to deform, and the door is fixed stably and firmly after closing. When the door is opened, the weight of the door panel 2 relies on the hinge 3 to temporarily bear the weight. Since the hidden door is opened less frequently, the hinge 3 only temporarily bears the weight when it is opened, minimizing the deformation of the hinge 3. During door closing, the rack-mounted tongue 22 is inserted into the load-bearing device 4. The rack 23 on the tongue 22 drives the third gear 482 within the load-bearing device 4, which in turn drives the second gear 481 and the first gear 461 to rotate, adjusting the height of the lifting rod 46 and, in turn, the height of the lifting plate 47. This allows for adjustable tightness of the tongue 22 when inserted into the load-bearing device 4. After the hidden door is closed, the lifting plate 47 within the load-bearing device 4 rises, tightening the tongue 22 while simultaneously supporting the weight of the door panel 2. When the door is opened, pressing the door panel 2, causing the push-type rebounder 5 to push the door panel 2 out. The tongue 22 with the rack 23, when pushed out, drives the third gear 482, the second gear 481, and the first gear 461 in opposite directions, causing the lifting plate 47 to slightly descend, allowing the tongue 22 to slide out more easily. To facilitate smoother insertion and removal of the tongue 22, the top surface of each roller 472 has a plane formed with a gradually downward slope toward the tongue 22, for example, 1%.

[0029] The high-precision hanging hidden door system for building decoration walls of the present invention adopts a push-pop-up opening and closing method, which can reduce the gap between the hidden door and the wall, and has a beautiful appearance. In addition, when the door is closed, the weight of the door mainly relies on the load-bearing hanger, and the hanging installation is not easy to deform. There will be no error in the size of the gap between the door and the wall. After the door is closed, it is hung and fixed, which is stable and firm, which is beneficial to safety.

[0030] The present invention is defined by the claims, but those skilled in the art may make various obvious changes or modifications based on the claims, all of which are within the spirit and scope of the present invention.
