Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a glass door hinge. Background Technology

[0002] Glass door hinges are crucial components connecting glass doors to their frames and enabling their rotation. Their installation must take into account the fragility of glass and the fact that threaded holes cannot be directly drilled into it. Traditional hinges typically use pre-drilled holes in the hinge blades for fixing with self-tapping screws. However, directly tapping the glass can easily cause stress concentration, leading to cracks and compromising structural safety and lifespan.

[0003] To address the aforementioned issues, existing technologies often employ a clamping structure to connect the glass to the hinge. For example, the glass door hinge disclosed in Chinese Patent Publication No. CN210918622U features a clamping assembly on the inner side of the hinge body. Positioning and fixing components located on both sides of the glass clamp the glass, and through holes are formed in the glass for the connecting components to pass through. While this structure avoids direct tapping of the glass, it still has certain limitations.

[0004] In practical use, existing clamp-on hinges often have fixing components protruding from the glass surface, affecting the overall aesthetics. Furthermore, the mounting holes on the glass are usually fixed in position, making it difficult to fine-tune the glass's position once installed. If the glass door's position needs to be adjusted due to installation errors or changes in usage requirements, new holes often need to be drilled, which is not only cumbersome but also increases the risk of glass breakage, limiting its adaptability and convenience in actual engineering projects. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a glass door hinge to solve the above problems.

[0006] A glass door hinge includes two leaf bodies rotatably connected by a pivot assembly. At least one of the leaf bodies is provided with an adjustment assembly for installing a glass door. The adjustment assembly includes a rubber ring, an adjustment seat, and a locking screw. The rubber ring is sleeved on the outside of the adjustment seat. The leaf body is provided with at least one transverse adjustment groove. The end of the adjustment seat facing the leaf body is provided with an insert block. The insert block is inserted into the transverse adjustment groove and can slide along its length. The adjustment seat is provided with a transverse adjustment hole. The locking screw passes through the transverse adjustment hole and fixes the adjustment seat to the leaf body.

[0007] Specifically, the blade body is provided with screw holes for installing the locking screws, and there are two transverse adjustment slots and two insertion blocks, with the screw holes located between the two transverse adjustment slots.

[0008] Specifically, the adjustment assembly also includes an anti-loosening washer, which is disposed inside the adjustment seat and sleeved on the screw of the locking screw, for providing outward elastic force to the locking screw.

[0009] Specifically, the adjustment assembly also includes a decorative cover, which is disposed on the end of the adjustment seat and threadedly connected to the adjustment seat.

[0010] Specifically, a rubber gasket is provided between the blade body and the glass door, and the rubber gasket has a clearance hole for the adjustment component to pass through.

[0011] Specifically, the rotating shaft assembly includes a rotating shaft, a bushing, a first lifting shaft core, and a second lifting shaft core; the rotating shaft is disposed on one of the blade bodies, the bushing is disposed on the other blade body and rotates in cooperation with the rotating shaft, the first lifting shaft core is fixed to one of the blade bodies and sleeved on the rotating shaft, the second lifting shaft core is fixed to the other blade body and sleeved on the rotating shaft, and the first lifting shaft core and the second lifting shaft core move up and down axially during rotation.

[0012] Specifically, both of the aforementioned leaf bodies are equipped with the adjustment component.

[0013] Specifically, one of the page bodies is provided with the adjustment component, and the other page body is provided with a locking structure for locking the wall.

[0014] Specifically, the wall-locking structure includes a mounting hole on the blade body, an expansion sleeve embedded in the wall panel, a self-tapping screw passing through the mounting hole and connected to the expansion sleeve, and a cover on the blade body. The cover has a limiting protrusion at one end facing the blade body, and the blade body has a limiting hole that cooperates with the limiting protrusion.

[0015] Specifically, the mounting hole is a tapered hole, the self-tapping screw is a countersunk self-tapping screw, and the head of the countersunk self-tapping screw is inserted into the tapered hole.

[0016] The beneficial effects of this utility model are: 1. The glass door hinge of this application includes two leaf bodies rotatably connected by a pivot assembly. At least one leaf body is provided with an adjustment component for installing a glass door, and the other leaf body may be provided with an adjustment component for installing a glass door or a wall-locking structure for locking the wall. Different installation structures can be selected according to different application scenarios. 2. The adjusting seat is equipped with two inserts and the blade body is equipped with two transverse adjusting grooves. After assembly, it has a limiting function and can effectively prevent the adjusting seat from rotating relative to the blade body. 3. The two horizontal adjustment slots are elongated structures. The adjustment seat adjusts its horizontal position by sliding its insert within the horizontal adjustment slots, thereby causing the glass door to make minor horizontal adjustments. The horizontal adjustment holes on the adjustment seat provide a margin of movement for the locking screws, ensuring that the adjustment seat can still move horizontally and be reliably fixed even when the mounting hole position of the glass door is fixed. 4. Anti-loosening washers can be added to the locking screws. When the anti-loosening washers are compressed, they generate a rebound force, which keeps the locking screw and the thread in a continuous pressed state. The friction prevents loosening caused by vibration or external force, thus enhancing the reliability of the connection.

[0017] 5. After installation, the entire adjustment assembly is embedded in the mounting hole of the glass door, without protruding from the glass surface, ensuring good flatness. The adjustment base, as a metal component, provides strength support, and the rubber ring fitted on its exterior effectively prevents direct hard contact between the glass door and the adjustment base, playing a buffering and protective role.

Detailed Implementation

[0019] This utility model provides a glass door hinge. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0020] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Example 1 Please refer to Figures 1-6 This embodiment discloses a glass door hinge, including two leaf bodies 20 rotatably connected by a pivot assembly 10. The two leaf bodies 20 are provided with an adjustment assembly 40 for installing a glass door 30. The adjustment assembly 40 includes a rubber ring 41, an adjustment seat 42, and a locking screw 43. The adjustment seat 42 is made of metal. The rubber ring 41 is sleeved on the outside of the adjustment seat 42 to prevent the adjustment seat 42 from making hard contact with the glass door 30. The leaf body 20 is provided with at least one transverse adjustment groove 21. The transverse adjustment groove 21 has a long strip structure. The end of the adjustment seat 42 facing the leaf body 20 is provided with an insert 421. The insert 421 is inserted into the transverse adjustment groove 21 and can slide along the length direction of the transverse adjustment groove 21. The adjustment seat 42 is provided with a transverse adjustment hole 422. The transverse adjustment hole 422 has a long strip structure. The locking screw 43 passes through the transverse adjustment hole 422 and fixes the adjustment seat 42 to the leaf body 20.

[0022] During installation, inserting the insert block 421 into the transverse adjustment slot 21 allows the adjustment seat 42 to slide along the length of the transverse adjustment slot 21. The adjustment seat 42 is also provided with a transverse adjustment hole 422. After the locking screw 43 passes through the transverse adjustment hole 422, the adjustment seat 42 can be finally locked onto the blade body 20.

[0023] During installation, the operator first aligns the insert 421 of the adjusting seat 42 with and inserts it into the horizontal adjustment groove 21 of the blade body 20 to complete the initial positioning. Next, the adjusting seat 42, with the rubber ring 41 already fitted, is partially embedded into the pre-drilled mounting hole on the glass door 30. Then, the locking screw 43 is passed through the horizontal adjustment hole 422 of the adjusting seat 42 and initially screwed into the corresponding screw hole 22 on the blade body 20, without fully tightening it at this stage. Using the sliding engagement between the insert 421 and the horizontal adjustment groove 21, the adjusting seat 42 can be pushed to move the glass door 30 together for fine-tuning of its horizontal position. After the position of the glass door 30 is adjusted to the optimal level, the locking screw 43 is finally tightened to securely fix the adjusting seat 42 to the blade body 20, completing the entire installation process.

[0024] This application enables stepless adjustment of the lateral position of the glass door 30 after installation. The adjusting seat 42, through its insert 421, engages with the lateral adjusting groove 21 on the blade body 20, providing both sliding guidance and preventing rotation of the adjusting seat 42. The lateral adjusting hole 422 on the adjusting seat 42 provides the necessary movement space for the locking screw 43, thus ensuring lateral adjustment is still possible even with the glass door 30's mounting hole fixed. The entire adjusting assembly 40 is embedded in the mounting hole of the glass door 30 after installation, ensuring a flat and aesthetically pleasing glass surface. The rubber ring 41 fitted around the adjusting seat 42 effectively prevents direct hard contact between the metal adjusting seat 42 and the glass door 30, providing good buffering and protection. If an anti-loosening washer 44 is added to the locking screw 43, the rebound force generated after compression can be used to further enhance the reliability of the screw connection.

[0025] In summary, the glass door hinge of this embodiment solves the problem of difficulty in fine-tuning the position of the glass door 30 after installation through the ingenious sliding engagement structure of the insert 421 and the horizontal adjustment groove 21. The embedded design of its adjustment component 40 balances aesthetics and protection, achieving convenient, precise, and reliable installation, significantly improving the practicality and user experience of the glass door hinge.

[0026] In a preferred embodiment, the leaf body 20 is provided with screw holes 22 for installing locking screws 43. There are two transverse adjustment slots 21 and two inserts 421, with the screw holes 22 located between the two transverse adjustment slots 21. During installation, the two inserts 421 are inserted into their respective transverse adjustment slots 21, forming a stable two-point support, effectively preventing the adjustment seat 42 from deflecting under force. The screw holes 22 are located in the center between the two transverse adjustment slots 21, allowing the locking screws 43 to apply force evenly during tightening, ensuring the balance and reliability of the adjustment seat 42. This symmetrical layout enhances the stability of the connection structure and facilitates the stable load-bearing of the glass door 30.

[0027] In a preferred embodiment, the adjusting assembly 40 further includes an anti-loosening washer 44, which is disposed within the adjusting seat 42 and fitted onto the threaded shaft of the locking screw 43, providing an outward elastic force to the locking screw 43. During installation, the anti-loosening washer 44 is compressed between the adjusting seat 42 and the nut of the locking screw 43. When the locking screw 43 is tightened, the continuous reverse elastic force generated by the anti-loosening washer 44 ensures that the screw threads remain pressed together, effectively resisting vibrations caused by frequent opening and closing of the door, thereby preventing the locking screw 43 from loosening and falling off, and improving the long-term safety of the glass door hinge.

[0028] In a preferred embodiment, the adjusting assembly 40 further includes a decorative cover 45, which is disposed on the end of the adjusting seat 42 and threadedly connected to the adjusting seat 42. After the adjusting seat 42 and the locking screw 43 are installed in place, the decorative cover 45 is screwed onto the thread at the end of the adjusting seat 42 to completely conceal the internal adjusting structure. The decorative cover 45 not only makes the hinge look neater and more aesthetically pleasing, but also serves to prevent dust and foreign objects from entering the interior of the adjusting assembly 40, which helps to maintain the long-term stability of the hinge function.

[0029] In a preferred embodiment, a rubber gasket 50 is provided between the hinge body 20 and the glass door 30. The rubber gasket 50 has a clearance hole 51 for the adjustment component 40 to pass through. During installation, the rubber gasket 50 is first placed between the contact surfaces of the hinge body 20 and the glass door 30. The front end of the adjustment seat 42 of the adjustment component 40 passes through the clearance hole 51 on the rubber gasket 50 and then enters the mounting hole of the glass door 30. The rubber gasket 50 can fill the gap between the hinge body 20 and the glass door 30 to prevent hard contact. On the other hand, it can increase the friction to help prevent the hinge from sliding, and its elastic properties also play a certain role in cushioning and shock absorption.

[0030] In a preferred embodiment, the pivot assembly 10 includes a pivot 11, a bushing 12, a first lifting pivot 13, and a second lifting pivot 14. The pivot 11 is disposed on one of the leaf bodies 20, the bushing 12 is disposed on the other leaf body 20 and rotatably engages with the pivot 11, the first lifting pivot 13 is fixed to one of the leaf bodies 20 and sleeved on the pivot 11, and the second lifting pivot 14 is fixed to the other leaf body 20 and sleeved on the pivot 11. The first lifting pivot 13 and the second lifting pivot 14 move axially up and down during rotation. The upper end of the first lifting pivot 13 has an arc-shaped first guide surface, and the lower end of the second lifting pivot 14 has an arc-shaped second guide surface. The movement of the first and second guide surfaces allows for the lifting and lowering of the first lifting pivot 13 and the second lifting pivot 14. When the glass door 30 rotates around the pivot 11, the first lifting pivot 13 and the second lifting pivot 14, fixed on the two leaf bodies 20, rotate relative to each other. With the help of its curved guide surface at the end, axial displacement is generated during rotation, i.e., an automatic lifting effect. This design allows the glass door 30 to be slightly raised when opening and smoothly lowered when closing, which not only effectively avoids friction and wear between the glass door 30 and the ground, but also realizes the functions of automatic positioning and buffering, improving the smoothness and durability of use.

[0031] Example 2 Please refer to Figures 7-11 The main difference between this embodiment and Embodiment 1 is that the glass door hinge disclosed in this embodiment includes two leaf bodies 20 rotatably connected by a pivot assembly 10. One leaf body 20 is provided with an adjustment assembly 40 for installing a glass door 30, while the other leaf body 20 is provided with a locking structure 60 for fixing to a wall panel 70. This asymmetrical design, with adjustment on one side and fixing on the other, makes this hinge particularly suitable for application scenarios where the glass door 30 is directly installed on the wall panel 70, thus broadening the product's applicability.

[0032] Furthermore, the wall-locking structure 60 includes a mounting hole 61 on the blade body 20, an expansion sleeve 62 that needs to be pre-embedded in the wall panel 70, a self-tapping screw 63 that passes through the mounting hole 61 and is threaded to the expansion sleeve 62, and a cover 64 that covers the blade body 20 to conceal the mounting structure. The end of the cover 64 facing the blade body 20 has a limiting protrusion 641, while the blade body 20 has a limiting hole 23 that matches the shape of the limiting protrusion 641. During installation, the blade body 20 is first fixed to the wall panel 70 with the self-tapping screw 63, and then the limiting protrusion 641 of the cover 64 is aligned with the limiting hole 23 on the blade body 20 and pressed down. The tight fit between the limiting protrusion 641 and the limiting hole 23 effectively prevents the cover 64 from loosening or falling off during daily use, while ensuring the accuracy of the cover 64's installation position and maintaining a neat and uniform appearance.

[0033] Furthermore, the mounting hole 61 in the wall-locking structure 60 is designed as a tapered hole, while the matching self-tapping screw 63 is a countersunk self-tapping screw. During installation, the head of the countersunk self-tapping screw can be completely recessed and fitted into the tapered hole. This countersunk design ensures that after the screw is tightened, its head will not protrude from the surface of the blade body 20, thereby ensuring a flat and fitted fit between the blade body 20 and the wall surface 70. This not only makes the appearance simpler and more aesthetically pleasing but also avoids installation gaps or stress concentration problems that may be caused by protruding screw heads, improving the stability and reliability of the connection.

[0034] The preferred embodiments of this utility model have been described in detail above. However, this invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this invention.
