Description

Technical Field

[0001] This utility model relates to the technical field of shower room accessories, and in particular to a top and bottom wall hinge structure with a large adjustable size. Background Technology

[0002] Shower enclosure accessories refer to the connecting parts installed on the shower enclosure profiles or glass to facilitate the opening and closing of the shower enclosure. They are widely used in daily life. Among them, hinges are often used for connecting the hinged doors of shower enclosures.

[0003] Most existing hinge structures cannot be directly connected and installed from top to bottom, which means that the glass needs to be fixed and the glass holes locked at the same time during installation, resulting in poor installation convenience.

[0004] Therefore, it is urgent to research and develop a large-size adjustable top and bottom wall hinge structure to solve the above-mentioned technical defects. Summary of the Invention

[0005] The purpose of this utility model is to provide a large-adjustable top and bottom wall hinge structure, which can improve the convenience of installing shower room glass using this large-adjustable top and bottom wall hinge structure.

[0006] To achieve the above objectives, this utility model provides a large-adjustable top and bottom wall hinge structure, the specific implementation of which is as follows:

[0007] A large-size adjustable top and bottom wall hinge structure includes:

[0008] The hinge body is used to pre-fix it to the upper and lower positions of the wall;

[0009] A bushing is provided on the hinge body;

[0010] A hinge glass clip is used to hold the glass in a position that matches the hinge body;

[0011] A pivot post is provided on the hinge glass clamp, which is inserted and engaged with the bushing, and rotates relative to the bushing in the circumferential direction of the bushing. The hinge glass clamp is detachably connected to the hinge body through the pivot post.

[0012] The locking element is positioned opposite the hinge glass clip;

[0013] A connecting screw is provided on the locking member to pass through the locking member and the glass and lock into the hinge glass clamp.

[0014] This utility model discloses a large-size adjustable top and bottom wall hinge structure. Compared with the prior art, by making the hinge body and the hinge glass clip detachable, during installation, the upper and lower hinge bodies can be precisely pre-fixed to the wall first. Then, the hinge glass clip and locking device are used to clamp the glass to the position of the two hinge bodies. The two hinge glass clips are then hooked onto the hinge body at one time through the insertion of the pivot column and the bushing. This greatly simplifies the installation process, solves the problem of having to hold the glass and tighten the screws at the same time in the prior art, and improves the installation efficiency and convenience. At the same time, the locking action of the connecting screws ensures that the glass is firmly clamped.

[0015] In some embodiments, the hinge body has a mounting hole, and the bushing is fitted into the mounting hole.

[0016] The mounting hole and bushing are fitted together to achieve stable and precise positioning of the bushing on the hinge body, which facilitates the assembly and replacement of the bushing and ensures that the pivot can rotate smoothly inside it, providing a reliable structural foundation for the opening and closing function of the hinge.

[0017] In some embodiments, the hinge body has a limiting hole for the through mounting hole, and a limiting screw is provided in the limiting hole. The end of the limiting screw extends into the bushing and engages with the limiting groove on the rotating shaft.

[0018] By using the limiting screw and the limiting groove to limit the movement, the hinge can be effectively prevented from axially moving within the bushing or from accidentally coming out of the bushing during rotation. This improves the stability and safety of the hinge during operation and avoids the risk of the glass door tipping over due to hinge dislocation. On the other hand, the smoothness of the glass door's rotation can be adjusted by the tightness of the limiting screw.

[0019] In some embodiments, the locking member has a first countersunk hole penetrating the locking member, the hinge glass clip has a first connecting hole matching the first countersunk hole, and the connecting screw passes through the first countersunk hole and the glass and is screwed into the first connecting hole.

[0020] By providing a first countersunk hole on the locking component, the head of the connecting screw is allowed to sink into the locking component, avoiding the screw head protruding and affecting the appearance or causing interference; and by providing a first connecting hole on the hinge glass clamp, together with the first countersunk hole, a through fastening channel is formed, ensuring that the connecting screw can smoothly pass through all components and tightly lock the glass between the hinge glass clamp and the locking component.

[0021] In some embodiments, a first washer is provided between the hinge glass clip and the glass, the first washer having a first through hole for the connecting screw to pass through, and a second washer is provided between the locking member and the glass, the second washer having a second through hole for the connecting screw to pass through.

[0022] By setting a first gasket between the hinge glass clip and the glass, and a second gasket between the locking element and the glass, a buffer and isolation layer is formed between the hinge glass clip and the glass, as well as between the locking element and the glass. This effectively disperses the locking force, prevents the glass from cracking due to excessive local stress, and avoids direct contact between metal parts and scratches on the glass surface, thus playing a crucial protective role for the glass.

[0023] In some embodiments, the hinge glass clip has a first reserved hole on the side facing the first gasket, and a third through hole is opened on the first gasket at the position corresponding to the first reserved hole, so that the anti-collision soft rubber can pass through the third through hole and be embedded in the first reserved hole.

[0024] After the anti-collision soft rubber is inserted into the first reserved hole through the third through hole, its end contacts the glass, thereby playing a buffering and shock-absorbing role when the glass is closed, significantly reducing impact noise and reducing metal wear on the hinge itself, improving the comfort and lifespan of the product.

[0025] In some embodiments, a washer is fitted onto the connecting screw, and the washer is used to fix it in an opening in the glass to prevent the connecting screw from directly contacting the glass.

[0026] By fitting a washer fixed inside the opening in the glass onto the connecting screw, it acts as an isolation element between the connecting screw and the glass hole wall, effectively preventing the hard screw metal from directly contacting the glass. This avoids stress concentration or cracking of the glass hole edge due to slight displacement during screw tightening or daily use, further enhancing the reliability and safety of the installation.

[0027] In some embodiments, the hinge body is provided with a second connecting hole for connecting to the pivot aluminum material fixed to the wall, so that the two hinge bodies are located at the top and bottom positions of the pivot aluminum material, respectively.

[0028] The hinge body is also provided with a third connecting hole for fixing to the wall with screws.

[0029] The second connecting hole ensures a reliable connection between the hinge body and the aluminum shaft, guaranteeing the coaxiality of the upper and lower hinge bodies and the overall structural strength. The third connecting hole enables direct fixing of the hinge body to the wall. This dual fixing mechanism greatly enhances the hinge's load-bearing capacity and installation stability, ensuring the safe suspension and stable operation of the glass door.

[0030] In some embodiments, the hinge body has a first decorative cover and a second decorative cover. The first decorative cover is used to cover and shield the second connecting hole. The hinge body has an interlocking groove at the position corresponding to the third connecting hole. The second decorative cover is embedded in the interlocking groove to shield the interlocking groove and the third connecting hole.

[0031] The screw holes and grooves used for connection are completely covered by the first and second decorative covers, resulting in a cleaner and more aesthetically pleasing appearance after installation. This achieves the effect of concealed installation and also serves to prevent dust and screw corrosion.

[0032] In some embodiments, the outer wall of the locking member is provided with an elastic element, and the locking member is fitted with a third decorative cover, the end of the elastic element abutting against the groove wall of the receiving groove opened on the third decorative cover.

[0033] By utilizing the elastic force provided by the elastic element, a tight fit is formed between the third decorative cover and the locking element, ensuring that the third decorative cover will not loosen due to vibration or slight external force after installation. This allows for convenient disassembly and maintenance, while also maintaining stability during daily use and preserving the overall aesthetic appearance of the final product.

[0034] Based on the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0035] By making the hinge body and hinge glass clips detachable, during installation, the upper and lower hinge bodies can be precisely pre-fixed to the wall first. Then, the hinge glass clips and locking devices are used to clamp the glass in the positions corresponding to the two hinge bodies. The two hinge glass clips are then attached to the hinge body at one time through the insertion of the pivot post and the bushing. This greatly simplifies the installation process, solves the problem of having to hold the glass while tightening the screws in the previous technology, and improves installation efficiency and convenience. At the same time, the locking action of the connecting screws ensures that the glass is firmly clamped. Attached Figure Description

[0045] like Figure 1-3 As shown in the figure, in some embodiments of the large adjustable size wall hinge structure provided in this embodiment, the hinge body 7 is provided with a mounting hole, and the bushing 5 is fitted into the mounting hole.

[0046] The mounting hole and bushing 5 are fitted together to achieve stable and precise positioning of bushing 5 on hinge body 7, which facilitates the assembly and replacement of bushing 5 and ensures that the pivot column 2 can rotate smoothly inside it, providing a reliable structural foundation for the opening and closing function of the hinge.

[0047] In some embodiments, the hinge body 7 has a limiting hole for the through mounting hole, and a limiting screw 6 is provided in the limiting hole. The end of the limiting screw 6 extends into the bushing 5 and engages with the limiting groove on the rotating shaft 2.

[0048] By limiting the engagement of the limiting screw 6 with the limiting groove, on the one hand, it can effectively prevent the pivot column 2 from axially moving within the bushing 5 or from accidentally dislodging from the bushing 5 during rotation, thereby improving the stability and safety of the hinge in the working state and avoiding the risk of the glass door tipping over due to hinge dislocation; on the other hand, the smoothness of the glass door's rotation can be adjusted by the degree of tightening of the limiting screw 6.

[0049] In some embodiments, the locking member has a first countersunk hole 20 that penetrates the locking member, the hinge glass clip 1 has a first connecting hole 3 that matches the first countersunk hole 20, and the connecting screw 22 passes through the first countersunk hole 20 and the glass and is screwed into the first connecting hole 3.

[0050] By providing a first countersunk hole 20 on the locking component, the head of the connecting screw 22 is allowed to sink into the locking component, avoiding the screw head protruding and affecting the appearance or causing interference; and by providing a first connecting hole 3 on the hinge glass clip 1, together with the first countersunk hole 20, a through fastening channel is formed, ensuring that the connecting screw 22 can pass smoothly through all components and tightly lock the glass between the hinge glass clip 1 and the locking component.

[0051] In some embodiments, a first washer 15 is provided between the hinge glass clip 1 and the glass, and the first washer 15 has a first through hole 13 for the connecting screw 22 to pass through. A second washer 18 is provided between the locking member and the glass, and the second washer 18 has a second through hole 17 for the connecting screw 22 to pass through.

[0052] By setting a first gasket 15 between the hinge glass clip 1 and the glass, and a second gasket 18 between the locking member 21 and the glass, a buffer and isolation layer is formed between the hinge glass clip 1 and the glass, and between the locking member and the glass. This effectively disperses the locking force, prevents the glass from cracking due to excessive local stress, and avoids direct contact between metal parts and scratches on the glass surface, thus playing a crucial protective role for the glass.

[0053] In some embodiments, the hinge glass clip 1 has a first reserved hole 4 on the side facing the first gasket 15, and a third through hole 14 is opened on the first gasket 15 at the position corresponding to the first reserved hole 4, so that the anti-collision soft rubber 11 can pass through the third through hole 14 and be embedded in the first reserved hole 4.

[0054] After the anti-collision soft rubber 11 is inserted into the first reserved hole 4 through the third through hole 14, its end contacts the glass, thereby playing a buffering and shock-absorbing role when the glass is closed, significantly reducing impact noise and reducing metal wear of the hinge itself, and improving the comfort and life of the product.

[0055] In some embodiments, a washer 16 is fitted onto the connecting screw 22, and the washer 16 is used to fix it in an opening in the glass to prevent the connecting screw 22 from directly contacting the glass.

[0056] By fitting a washer 16, which is fixed inside the opening in the glass, onto the connecting screw 22, it acts as an isolation element between the connecting screw 22 and the glass hole wall, effectively preventing the hard screw metal from directly contacting the glass. This avoids stress concentration or cracking of the glass hole edge due to slight displacement during screw tightening or daily use, further enhancing the reliability and safety of the installation.
