Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically to a single-opening buffer glass hinge. Background Technology

[0002] A glass door hinge is a connector used to install glass doors. It typically consists of a fixed hinge, a movable hinge, and a pivot. The hinges are connected to the frame and the glass door respectively, and then connected by the pivot, allowing the frame and glass door to move together. However, current glass door hinges have relatively low springback force and insufficient return force, making it difficult to accurately pull the door back to the closed position. On the other hand, if the springback force is too high, a heavy glass door will quickly return to its original position, which can damage the connection between the fixed and movable seats of the hinge, affecting its working performance.

[0003] To address the aforementioned technical problems, Chinese Patent No. CN218150384U discloses a single-opening hydraulic buffer glass door hinge, comprising a fixed base, a movable base, and a limiting shaft mounting base. The fixed base is fixedly connected to the limiting shaft mounting base, and the movable base is rotatably hinged to the limiting shaft mounting base via the limiting shaft. A limiting cam is provided in the middle section of the limiting shaft, and a damper is provided in the movable base corresponding to the limiting cam. The extended end of the damper contacts the fixed base, and a protrusion is provided at the end of the damping cylinder corresponding to the limiting cam. A first spring and a second spring are respectively provided on both sides of the damper to provide a return force for the limiting shaft, wherein the elastic force of the first spring is greater than that of the second spring.

[0004] While the aforementioned existing technical solution reduces the impact of the glass door body on the connection stability of the glass door hinge, the first and second springs used for buffering, as well as the damper, are all installed inside the limit shaft mounting base. The limit shaft mounting base is locked to the fixed base by two sets of bolts. When the door opening and closing causes a decrease in buffering resistance, there may be oil leakage from the damper or damage or breakage of the first and second springs. It is difficult for personnel to open the limit shaft mounting base to quickly inspect, repair, or replace the buffering components inside, thereby affecting the practicality of the device during use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figures 1-3 This utility model provides a technical solution:

[0022] A single-opening buffer glass hinge includes a fixed base 1, a connecting base 2 installed at one end of the fixed base 1, and an adjusting base 3 rotatably connected to the other end of the connecting base 2. Both the adjusting base 3 and the fixed base 1 have door connecting bases 4 installed at their bottom ends. A protective cover 5 is engaged with one side of the adjusting base 3 via a limiting mechanism. The limiting mechanism includes a connecting component, a limiting torsion component, and a protective component. The connecting component secures the protective cover 5 to the connecting base 2, the limiting torsion component releases the position of the protective cover 5, and the protective component protects the control components of the limiting torsion component. In use, the hinge allows the protective cover 5 to be secured to the connecting base 2 via the connecting component, the limiting torsion component to release the position of the protective cover 5, and the protective component to protect the control components of the limiting torsion component. The hinge features a simple structure and convenient operation. When inspecting components, personnel do not need to unscrew each set of bolts to disassemble the connecting base 2, saving disassembly and assembly time, increasing the efficiency of maintenance, and further improving its practicality.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the connecting assembly includes a rubber pad 6 installed on the side of the connecting seat 2 near the protective cover 5. One end of the rubber pad 6 has a mating groove extending into the interior of the connecting seat 2. A mating block 7, which is slidably connected to the mating groove, is installed on one side of the protective cover 5. A locking groove is provided inside the connecting seat 2 on one side of the mating groove. A movable rod 8 is rotatably connected to the inner wall of the locking groove. An extrusion plate 9 is sleeved on the outer side of the movable rod 8. The opposite ends of the extrusion plate 9 and the mating block 7 both have mutually fitting inclined surfaces. A stretching groove is provided on one side of the extrusion plate 9. The inner wall of the stretching groove and the inner wall of the locking groove are connected... The first spring 10 is installed. First, when the component used for buffering malfunctions, the sliding plate 15 can be opened and then the torsion plate 14 can be twisted to drive the movable rod 8 to rotate. At the same time, the limiting block 13 and the limiting groove can drive the pressing plate 9 to rotate smoothly around the center of the movable rod 8 for a certain distance, and pull the retracting plate 11 out from the inside of the slot. At this time, the rubber pad 6 fully rebounds and drives the docking block 7 and the slot opened on it away from the position of the retracting groove. At this time, the torsion plate 14 will not be locked again when it is released. Then the protective cover 5 can be removed to inspect and replace the components inside the connecting seat 2.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a retraction groove is formed inside the extrusion plate 9 at its inclined surface. A rotating rod is rotatably connected to the inside of the retraction groove. A retraction plate 11 is sleeved on the outside of the rotating rod. A guide surface that fits against the inclined surface is formed on one side of the retraction plate 11. A torsion spring 12 is installed between the rotating rod and the inner wall of the retraction groove. A slot is formed inside the mating block 7 at its inclined surface. Then, after the repair is completed, the outer wall of the protective cover 5 and the rubber pad 6 are attached together, so that the mating block 7 enters the mating groove and contacts the extrusion plate 9. After the inclined surfaces on the two contact, the extrusion plate 9 and the movable rod 8 are forced to rotate around the center. The limiting block 13 also slides inside the limiting groove to increase the stability during movement.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the limiting torsion assembly includes a limiting groove located inside the connecting seat 2 on one side of the engagement groove. A limiting block 13, slidably connected to the limiting groove, is installed at one end of the pressing plate 9. An extension groove is provided inside the connecting seat 2 on one side of the engagement groove. A torsion plate 14 is installed at one end of the movable rod 8 extending into the extension groove. The cross-sections of the limiting block 13 and the limiting groove are both arc-shaped. The center of the arc of the limiting block 13 is located at the same position as the axis of the movable rod 8. Furthermore, when the first spring 10 is stretched, the rubber pad 6 is also compressed until the mating block... After contact with the retraction plate 11, the inclined surface will fit against the guide surface, forcing the rotating rod to rotate inside the retraction groove. After the torsion spring 12 is squeezed and retracted, the retraction plate 11 also retracts to the inside of the retraction groove. After the slot on the docking block 7 is pushed to the retraction groove, the resistance disappears and the torsion spring 12 drives the retraction plate 11 to reset. The retraction plate 11 pops out to the inside of the slot. At this time, the protective cover 5 can be released. The rubber pad 6 rebounds a little and drives the docking block 7 to retract. After the slot moves, its inner wall abuts against one side of the retraction plate 11, completing the quick locking of the position of the protective cover 5.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the protective component includes a sliding groove on the outer wall of the connecting seat 2 located on one side of the extension groove. The inner side of the extension groove is connected to the inner side of the sliding groove. A sliding plate 15 is slidably connected to the inner side of the sliding groove. Synchronization grooves 16 are provided on both sides of the inner wall of the sliding groove. Synchronization blocks that are slidably connected to the synchronization grooves 16 are installed at both ends of the sliding plate 15. A magnetic block 17 is embedded at one end of the sliding plate 15. An iron block that attracts the magnetic block 17 is embedded in the inner wall of the sliding groove. Furthermore, after locking, two sets of latching grooves can be fastened together with the synchronization grooves 16 and the synchronization blocks to drive the sliding plate 15 close to the inner wall of the sliding groove, so that the magnetic block 17 and the iron block are attracted and positioned, thereby covering the torsion plate 14 to prevent the connection from becoming loose due to accidental contact after assembly.

[0027] The implementation principle of a single-opening buffer glass hinge in this application embodiment is as follows: When the buffer component malfunctions, the sliding plate 15 can be opened, and then the torsion plate 14 can be twisted to drive the movable rod 8 to rotate. At the same time, with the cooperation of the limiting block 13 and the limiting groove, the pressing plate 9 can be driven to rotate smoothly around the center of the movable rod 8 for a certain distance, pulling the retracting plate 11 out from the inside of the slot. At this time, the rubber pad 6 fully rebounds, causing the docking block 7 and the slot opened on it to move away from the position of the retracting slot. At this time, the torsion plate 14 will not be locked again when it is released. Then, the protective cover 5 can be removed to inspect and replace the components inside the connecting seat 2. After the repair is completed, the outer wall of the protective cover 5 and the rubber pad 6 are attached, so that the docking block 7 enters the inside of the docking groove and contacts the pressing plate 9. After the inclined surfaces on the two come into contact, the pressing plate 9 and the movable rod 8 are forced to rotate around the center. The limiting block 13 also slides inside the limiting groove to increase the stability during movement. When spring 10 is stretched, rubber pad 6 is also compressed until docking block 7 contacts retracting plate 11. The inclined surface will then fit with the guide surface, forcing the rotating rod to rotate inside the retracting groove. After torsion spring 12 is squeezed and retracted, retracting plate 11 also retracts to the inside of the retracting groove. After pushing the slot on docking block 7 to the retracting groove, the resistance disappears and torsion spring 12 drives retracting plate 11 to reset. Retracting plate 11 pops out to the inside of the slot. At this time, protective cover 5 can be released. Rubber pad 6 rebounds a small section and drives docking block 7 to retract. After the slot moves, its inner wall abuts against one side of retracting plate 11, completing the quick locking of protective cover 5. After locking, two sets of latching slots can be fastened together with synchronous slot 16 and synchronous block to drive sliding plate 15 close to the inner wall of sliding groove, allowing magnetic block 17 and iron block to be attracted and positioned. Then, torsion plate 14 is covered to prevent accidental contact after assembly, which may cause the connection to loosen.
