[0020] Reference Figure 1-2 A glass door lifting hinge with a buffer effect includes a single-ear seat 1 and a double-ear seat 2 installed on the glass body, a single-ear lower steel sleeve 3, and a lifting shaft 4. A first plane bearing 9 and a second plane bearing 10 are respectively engaged at the upper and lower ends of the single-ear seat 1. The single-ear seat 1 and the double-ear seat 2 are movably engaged at their connecting ends. The lifting shaft 4 is movably inserted into the single-ear lower steel sleeve 3, and a track groove is provided on the outer side of the single-ear lower steel sleeve 3. Steel balls 12 are evenly embedded in the outer wall of the lifting shaft 4. A rotating steel needle 11 is also movably extended and retractable on the outer side of the lifting shaft 4, and the rotating steel needle 11 movably passes through the track groove on the outer side of the single-ear lower steel sleeve 3. The lifting shaft 4 movably passes through the double-ear seat 2 and extends into the single-ear seat 1, and the inner cavity of the double-ear seat 2 is located within the lifting shaft. A double-eared upper steel sleeve 5 is inserted into the upper end of shaft 4. A spring 8 is movably inserted into the upper end of double-eared seat 2, passing through the double-eared upper steel sleeve 5 and abutting against the upper end of lifting shaft 4. A spring tail plug 7 is threadedly connected to the upper end of double-eared seat 2, which abuts against and fixes the upper end of double-eared upper steel sleeve 5. A hydraulic cylinder 13 is inserted through the bottom of double-eared seat 2, abutting against the lower end of lifting shaft 4. A hydraulic cylinder tail plug 6 is threadedly connected to the bottom of double-eared seat 2, which abuts against and fixes the lower end of hydraulic cylinder 13. A gasket 17 is fitted to the outside of single-eared seat 1. A panel 16 is provided on the outside of gasket 17. The glass body is located between panel 16 and gasket 17. An adhesive tube 20 is sleeved on the outside of single-eared seat 1. The adhesive tube 20 movably passes through the glass body. Panel 16 is fixedly connected to single-eared seat 1 by screw 18.
[0021] The outer side of the double-ear base 2 is provided with a matching base plate decorative cover 14, and the outer side of the panel 16 is provided with a matching panel decorative cover 15. Positioning beads 19 are movably embedded in the outer side of both the double-ear base 2 and the panel 16. The inner wall of the base plate decorative cover 14 and the panel decorative cover 15 is provided with a bead groove that mates with the positioning beads 19, which facilitates the portable installation of the base plate decorative cover 14 and the panel decorative cover 15.
[0022] During installation, the glass door is placed outside the single-ear seat 1, with the adhesive tube 20 penetrating through it. Then, the panel 16 is placed on top, and gaskets 17 are evenly distributed on the contact surfaces of the single-ear seat 1, panel 16, and glass door to protect the glass door. Finally, screws 18 are used to fix the panel 16 and single-ear seat 1, thus completing the installation of the glass door. Based on this structure, when the door is opened, the single-ear seat 1 and the lower steel sleeve 3 rotate with the door, causing the rotating steel needle 11 and the lifting shaft 4 to move upwards synchronously. At this time, the upper end of the lifting shaft 4 compresses the spring 8, and the hydraulic cylinder 13 changes from a compressed state to its free default length, thus opening the glass door. When the door is closed during use, when it is closed to less than 90 degrees, the spring 8 is in a compressed state. At this time, the compression force pushes the lifting shaft 4 to move downward back to its original position, so that the glass door has the ability to close automatically, that is, to achieve the effect of automatic closing. When it reaches a certain angle, the hydraulic cylinder 13 is compressed by the telescopic rod 4, so that the glass door has a pushing force, thereby preventing the glass door from closing immediately, thus reversing the effect of buffering the closing, reducing the impact force and noise of closing the door, and improving the overall practical effect.
