Technical Field
[0001] This utility model relates to the field of glass door installation, and in particular to a 180-degree connecting hinge for glass doors with damping buffer. Background Technology
[0002] Glass doors are a rather special type of door. Firstly, their thickness is insufficient to classify them as solid doors, and secondly, they are not considered irregularly shaped doors. In fact, they are a special type of door. Glass doors are made of either tempered glass or ordinary float glass, generally using 12mm thick glass. Tempered glass is both sturdy and safe.
[0003] Common glass doors are usually connected to the wall or another set of glass by hinges, but the current market lacks a hinge that has a soft-close effect when opening and closing and allows for a 180-degree connection between glass panes. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of the prior art as mentioned in the background section, and to propose a 180-degree connecting hinge for glass doors with damping buffer.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figure 1-4A damped, buffered 180-degree hinge for a glass door includes a first base 1, a second base 5, and two sets of glass bodies 25. A core 2 is provided on one side of the first base 1, and a first panel 3 is provided on the outer side of the core 2. A second panel 6 is provided on the outer side of the second base 5. One set of glass bodies 25 is snapped onto the outer side of the core 2 and located between the first base 1 and the first panel 3. The other set of glass bodies 25 is snapped onto the outer side of the second base 5 and located between the second base 5 and the second panel 6. A small shaft 9 is horizontally inserted through the center of the core 2. The outer side of the second base 5 is fixed. The second base 5 is fixedly connected to the sandwich 2 by the first screw 501. The outer side of the second base 5 is fixedly connected to the oil cylinder 14. The outer side of the oil cylinder 14 is fitted with a spring 12. The outer side of the spring 12 is connected to a T-pin 11. The T-pin 11 is hollow, and the oil cylinder 14 moves through the T-pin 11 and extends from the outer side of the sandwich 2 to the inner cavity. The outer side of the small shaft 9 is provided with a slot 902, and the slot 902 and the T-pin 11 are engaged. The bottom of the small shaft 9 located in the inner cavity of the sandwich 2 is fixedly connected to a protrusion 901, and the bottom of the protrusion 901 contacts the oil cylinder 14.
[0025] One set of glass bodies 25 has a first adhesive pad 19 and a second adhesive pad 20 on the contact surfaces between it and the first base 1 and the first panel 3, respectively. The other set of glass bodies 25 has a third adhesive pad 21 and a fourth adhesive pad 22 on the contact surfaces between it and the second base 5 and the second panel 6, respectively. Adhesive channels 18 are provided on the outer sides of both the first base 1 and the second base 5, and the first, second, third, and fourth adhesive pads 19, 20, 21, and 22 are all fitted over the outer sides of the adhesive channels 18. A first cover plate 4 is also provided on the outer side of the first panel 3, and a second cover plate 7 is provided on the outer side of the second panel 6. The first panel 3 and the first cover plate 4, as well as the second panel 6 and the second cover plate 7, are fixedly connected by panel fastening screws 8. The spring 12 is in a spring-extended state by default, and in this state, it pushes the outer T-pin 11 to abut against the slot 902 on the outer side of the small shaft 9. Anti-collision rubber 15 is fixedly connected to the outer side of the first base 1, and sandwich rubber 16 is also provided on both sides of the sandwich 2. The first base 1 and anti-collision rubber 15, as well as sandwich 2 and sandwich rubber 16, are fixedly connected by the second screw 24. The small shaft 9 is rotatably connected to the sandwich 2 on both sides by bearings 13, and the small shaft 9 is also fitted with a washer 23 on the outside of the bearings 13. Shaft pressure blocks 10 are also snapped on both sides of the small shaft 9, and the shaft pressure blocks 10 are fixed to the outside of the first base 1 by shaft pressure block screws 17. The washer 23 is located between the sandwich 2 and the shaft pressure block 10.
[0026] Based on the above structure, when installing the glass body 25, the operator first attaches the adhesive tube 18 to the outside of the first base 1 and the second base 5, then attaches the first adhesive pad 19 to the outside of the first base 1, and snaps a set of glass bodies 25 onto the outside of the outer sandwich 2 of the first base 1 with one side in contact with the first adhesive pad 19. The second adhesive pad 20 is attached to the other side of the set of glass bodies 25. The two sets of adhesive pads are used to protect the set of glass bodies 25. Then, the first panel 3 is snapped onto the outside of the second adhesive pad 20, and the panel fastening screw 8 is inserted into the outside of the first panel 3 to fix the first panel 3 to the first base 1. The set of glass bodies 25 is then pressed and fixed. Similarly, the fourth adhesive pad 22 is attached to the outside of the second base 5, and another set of glass bodies 25 is snapped onto the outside of the second base 5. Then, the third adhesive pad 21 is attached to the outside of the set of glass bodies 25 and the second panel 6 is covered. After the panel fastening screws 8 are inserted, the second panel 6 is fixed to the outside of the second base 5, thus completing the installation of the set of glass bodies 25. Then, the first cover plate 4 and the second cover plate 7 are respectively fitted on the outside of the first panel 3 and the second panel 6 for protection, that is, the connection of the two sets of glass bodies 25 in a 180-degree state is finally completed.
[0027] Furthermore, when the two assembled glass doors are in use, if the two glass bodies 25 are in their default 180-degree position, the spring 12 is in a free length but slightly pre-compressed state, and the hydraulic cylinder 14 is in a closed state. When the glass body 25 is in the open state, the spring 12 is in a compressed state, while the hydraulic cylinder 14 is in a free state. In the actual closing action, the glass body 25 rotates along with the small shaft 9 when closing, and the groove 902 on the outside of the small shaft 9 contacts the T-pin 11. At this time, the T-pin 11 and the spring 12 gradually change from a compressed state to a free length. As the small shaft 9 rotates, it drives the bottom protrusion 901 to contact the hydraulic cylinder 14, causing the hydraulic cylinder 14 to change from its original free length to a compressed state. This causes the hydraulic cylinder 14 to begin to be compressed, thus achieving a buffering effect and effectively reducing the noise problem when the glass door closes.
