For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0042] This embodiment records a frameless acrylic door structure connected by concealed hinges, which has no exposed hinges outside the door, and the overall appearance of the structure is more simple and beautiful.

[0043] like Figures 1 to 3 As shown, the frameless structure of the acrylic door includes a side handle 1, an acrylic door 2, a 45° right-angle shell 3, a frame 4, a concealed hinge fixing block 5, a concealed hinge 6 and an L-shaped aluminum alloy part 7.

[0044] The side handle 1 is longitudinally installed on one side of the acrylic door 2 and protrudes outward to facilitate the operator to open the door. The acrylic door 2 of this embodiment is a frameless door, which is not limited to acrylic material, and can also be a frameless door structure made of other materials. L-shaped aluminum alloy parts 7 are installed on the upper and lower ends of the other side of the acrylic door 2, and two concealed hinge fixing blocks 5 are respectively installed on the frame 4 at positions matching the L-shaped aluminum alloy parts 7. The concealed hinge fixing blocks 5 are connected to the L-shaped aluminum alloy parts 7 through concealed hinges 6. The acrylic door 2 is installed on the frame 4. After the acrylic door 2 is closed, there is no exposed hinge, and only the protruding side handle 1 and the door lock 11 installed on the acrylic door 2 can be seen.

[0045] Specifically, Figures 4 to 10As shown, the L-shaped aluminum alloy part 7 is composed of two side plates in an L-shaped structure, wherein a first annular slot 7.1 is provided in the middle of one of the side plates, and a rectangular slot 7.2 protruding inwards is provided in the middle of the first annular slot 7.1, which is used to accommodate the leaf base of the concealed hinge 6, and a first threaded hole 7.3 is symmetrically arranged above and below the rectangular slot 7.2 in the first annular slot 7.1, which is used to fix the leaf of the concealed hinge 6, and a plurality of threaded columns 7.4 are symmetrically arranged above and below the other side plate, which are used to install the L-shaped aluminum alloy part 7 on the acrylic door 2, such as in this embodiment, two threaded columns 7.4 are arranged above and below the rectangular slot 7.2. At the position where the L-shaped aluminum alloy part 7 is installed, the outer side surface and end surface of the acrylic door 2 are respectively indented inwards, and the indentation depth is the thickness of the side plate of the L-shaped aluminum alloy part 7. The acrylic door 2 is provided with a U-shaped groove 2.1 indented inward from the end surface at the position where the L-shaped aluminum alloy part 7 is installed, so as to prevent the acrylic door 2 from obstructing the installation of the leaf base, and mounting holes 2.2 matching the threaded column 7.4 are provided on the upper and lower sides of the U-shaped groove 2.1. The threaded column 7.4 of the L-shaped aluminum alloy part 7 is inserted from the outside to the inside into the mounting hole 2.2 and installed on the acrylic door 2, and fixed by the hexagon socket screw 10. Preferably, the hexagon socket screw 10 is sequentially covered with a metal annular flat washer 8 and a rubber annular flat washer 9, which can avoid damaging the door surface and facilitate the adjustment of the locking force. After fixing, the outer side surface of the L-shaped aluminum alloy part 7 is flush with the outer surface of the acrylic door 2. In this embodiment, the acrylic door 2 and the L-shaped aluminum alloy part 7 adopt the same color system, and the joints between the two are flush, and they look almost integrated in appearance.

[0046] like Figures 11 to 14 As shown, the acrylic door 2 of this embodiment is installed on the vertical square tube 4.1 of the frame 4, and the 45° right angle shell 3 is wrapped around the outside of the vertical square tube 4.1 on which the acrylic door 2 is installed, and a gap matching the thickness of the concealed hinge fixing block 5 is left between the inner surfaces of both ends of the 45° right angle shell 3 and the vertical square tube 4.1. An annular hole 3.1 is provided on the 45° right angle shell 3 at a position matching the annular slot 7.1.

[0047] The front end of the concealed hinge fixing block 5 has a second annular slot 5.1 with an opening on one side, and the size of the second annular slot 5.1 matches the annular hole 3.1. The second annular slot 5.1 has second threaded holes 5.2 at the upper and lower ends, respectively, for fixing the concealed hinge 6, and the middle part is a transparent rectangular hole 5.3, for accommodating the leaf base of the concealed hinge 6. The rear end of the concealed hinge fixing block 5 is provided with three long slots 5.4 from top to bottom. The vertical square tube 4.1 is provided with a third threaded hole 4.2 matching the long slots 5.4. The front end of the concealed hinge fixing block 5 on the side where the acrylic door 2 is to be installed is inserted into the gap between the 45° right-angle housing 3 and the vertical square tube 4.1, the long slot 5.4 is coaxially opposite to the third threaded hole 4.2, and the concealed hinge fixing block 5 is fixed to the vertical square tube 4.1 by a hexagon socket screw 10, and the annular slot 5.1 is located inside the annular hole 3.1. In this embodiment, the installation position of the concealed hinge fixing block 5 can be adjusted within a certain range through the long slot hole 5.4, so as to facilitate the installation of the concealed hinge 6.

[0048] In this embodiment, the acrylic door 2 is fixed to the frame 4 by means of a concealed hinge 6. Figures 15 to 17 As shown, the bottom of the rear leaf of the concealed hinge 6 is inserted into the rectangular hole 5.3, and the flat head screw 12 is screwed into the second threaded hole 5.2 to fix the rear leaf of the concealed hinge 6 to the concealed hinge fixing block 5. The bottom of the front leaf of the concealed hinge 6 is inserted into the rectangular slot 7.2, and the flat head screw 12 is screwed into the first threaded hole 7.3 to fix the front leaf of the concealed hinge 6 to the L-shaped aluminum alloy part 7.

[0049] After the two leaves of the concealed hinge 6 are respectively installed on the concealed hinge fixing block 5 and the L-shaped aluminum alloy part 7, the acrylic door 2 is installed and fixed on the frame 4. After the acrylic door 2 is closed, only the protruding edge handle 1 and the door lock 11 can be seen outside the frameless structure of the acrylic door.

[0050] This embodiment is not limited to the installation of the acrylic door 2 , but is also applicable to the fixed connection of other doors, windows, etc. on the frame 4 .

[0051] Although the principle of the present invention is described in detail above in conjunction with the preferred embodiments of the present invention, those skilled in the art should understand that the above embodiments are merely explanations of the exemplary implementation of the present invention, and are not intended to limit the scope of the present invention.
