Description

Technical Field

[0001] This utility model relates to the field of hardware hinge technology, and in particular to an inward and outward opening hinge structure suitable for shower rooms, glass doors and other scenarios. Background Technology

[0002] The design and application of existing shower enclosure hinges still have several problems that urgently need to be solved:

[0003] First, the installation method is complex and affects waterproofing performance. Many traditional inward and outward opening hinges require a pre-cut notch in the edge of the glass door for proper installation. When this notch is made, the continuous waterproof sealant strip is inevitably interrupted at the hinge, creating a significant weak point in the waterproofing. During showering, water can easily seep through this interruption, making the bathroom floor slippery, affecting both the user experience and safety.

[0004] Secondly, the limiting and positioning functions are insufficient, resulting in poor reliability. Many existing hinges have simple limiting structures, relying on the weak force of elastic elements, or have small limiting contact surfaces, making them prone to wear, deformation, or failure after long-term use. This may cause the door to open beyond the preset range, colliding with walls, other bathroom fixtures, or adjacent glass, causing damage to the hinge itself, the door, and even related facilities.

[0005] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an inward and outward hinge structure with good waterproof performance.

[0007] This utility model is achieved through the following technical solution:

[0008] To solve the above-mentioned technical problems, this utility model provides an inward and outward hinge structure, including a fixed page and a movable page. One end of the fixed page is provided with a rotating seat protruding inward therefrom, and the rotating seat is provided with a rotating groove. One end of the movable page is provided with a rotating block extending from its end toward the fixed page and protruding inward therefrom. The rotating block is rotatably accommodated in the rotating groove and is rotatably connected to the rotating seat through a rotating shaft.

[0009] To further address the technical problem to be solved by this utility model, the present utility model provides an inward and outward hinge structure in which a limiting mechanism is provided between the fixed page and the movable page. The limiting mechanism includes an arc-shaped limiting groove provided on the side of the rotating block, and at least one limiting member is provided at the corresponding position of the rotating seat. The end of the limiting member extends into the limiting groove to limit the rotation angle of the movable page relative to the fixed page.

[0010] In order to further solve the technical problem to be solved by this utility model, the present utility model provides an inward and outward hinge structure in which the limiting member is a set screw or a screw, and the rotating seat is provided with a threaded hole that cooperates with the limiting member.

[0011] In order to further solve the technical problem to be solved by this utility model, in the internal and external hinge structure provided by this utility model, the rotating seat is provided with a plurality of threaded holes at the corresponding position, and the plurality of threaded holes are arranged along an arc path that matches the arc trajectory of the limiting groove.

[0012] In order to further solve the technical problem to be solved by this utility model, in the internal and external hinge structure provided by this utility model, the bottom of the rotating groove and the end of the rotating block are both arc-shaped.

[0013] To further address the technical problem to be solved by this utility model, in the inward and outward opening hinge structure provided by this utility model, one of the ends of the fixed page and the movable page is convex arc-shaped and the other is concave arc-shaped.

[0014] To further address the technical problems to be solved by this utility model, the present utility model provides an inward and outward hinge structure, which further includes a first clamping assembly. The first clamping assembly includes a first clamping plate disposed opposite to the inner side of the fixed page. The inner side of the fixed page is provided with a plurality of first studs. A plurality of first fasteners are provided between the first studs and the first clamping plate. The first clamping plate and the fixed page cooperate to clamp the glass between them.

[0015] To further address the technical problems to be solved by this utility model, the present utility model provides an inward and outward hinge structure, which further includes a second clamping component. The second clamping component includes a second clamping plate disposed opposite to the inner side of the movable page. A plurality of second studs are provided on the inner side of the movable page. A plurality of second fasteners are provided between the second studs and the second clamping plate. The second clamping plate and the movable page cooperate to clamp the glass between them.

[0016] To further address the technical problems to be solved by this utility model, this utility model provides an inward and outward hinge structure in which the rotating block is detachably connected to one end of the movable page.

[0017] To further address the technical problems addressed by this utility model, the present utility model provides an inward and outward hinge structure in which at least two rotating blocks are provided, spaced apart along the ends of the movable page; correspondingly, at least two rotating slots are also provided on the rotating seat at positions corresponding to the rotating blocks.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] This invention fundamentally solves the problem of waterproof sealant strips having to be interrupted, severely impacting waterproofing performance, through an offset rotating structure (i.e., both the rotating base and the rotating block protrude inwards towards the hinge). Furthermore, by providing an arc-shaped limiting groove on the rotating block and an adjustable limiting component on the rotating base, it achieves precise, reliable, and flexible adjustment of the door opening angle. In summary, this invention features a simple and ingenious structure, offering convenient installation, stable load-bearing capacity, and excellent waterproofing performance. It also effectively prevents excessive opening and closing of the door and collisions, significantly improving product safety, durability, and user experience. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Please see Figures 1 to 4 This embodiment provides an inward and outward opening hinge structure, which is particularly suitable as a glass door hinge for shower rooms. The hinge structure includes a fixed leaf 1 and a movable leaf 2.

[0027] like Figure 1 and Figure 2As shown, the fixing page 1 is typically used to connect to a fixed wall or a fixed glass panel, such as glass panel 91. One end of the fixing page 1 is provided with an integrally formed rotating seat 3 that protrudes inward (i.e., towards the side facing the glass panel), and the rotating seat 3 is provided with a rotating groove 31.

[0028] The movable hinge 2 is used to connect a rotatable door leaf, such as a glass door 92. One end of the movable hinge has a rotating block 4. This rotating block 4 also protrudes inwards, extending from the end of the movable hinge 2 towards the fixed hinge 1. This design allows the rotating block 4 to be rotatably accommodated in the rotating groove 31 of the rotating seat 3. During assembly, a rotating shaft 5 passes sequentially through the rotating seat 3 and the rotating block 4 accommodated therein, thereby rotatably connecting the movable hinge 2 and the fixed hinge 1, realizing the basic opening and closing function of the hinge.

[0029] To facilitate the installation of the glass door panel, this embodiment also includes a first clamping assembly and a second clamping assembly. Specifically, the first clamping assembly is used to install the fixed leaf 1 onto the fixed glass panel 91. It includes a first clamping plate 7, which is disposed opposite to the inner side of the fixed leaf 1. Several (e.g., two) first studs 11 are fixed on the inner side of the fixed leaf 1, and corresponding through holes are opened on the first clamping plate 7. During installation, the fixed glass 91 is placed between the fixed leaf 1 and the first clamping plate 7, and then several first fasteners 71 (e.g., screws) are passed through the first clamping plate 7 and threadedly connected to the first studs 11. By tightening the first fasteners 71, the fixed glass 91 can be firmly clamped by the clamping force of the first clamping plate 7 and the fixed leaf 1. Similarly, the second clamping assembly is used to install the movable leaf 2 onto the glass door 92. Its structure is similar to that of the first clamping assembly, including a second clamping plate 8, a second stud 21, and a second fastener 81, which clamp the glass door 92 between the movable leaf 2 and the second clamping plate 8 in the same manner.

[0030] The limiting mechanism in this embodiment is used to precisely control the opening angle of the glass door 92. For example... Figure 2 and Figure 3 As shown, the limiting mechanism includes an arc-shaped limiting groove 41 on the side of the rotating block 4 and a limiting member 6 on the rotating seat 3. In this embodiment, the limiting member 6 is preferably a set screw or a screw, the end of which extends into the limiting groove 41. When the movable page 2 rotates around the rotating shaft 5, the rotating block 4 rotates accordingly, and the two ends of the limiting groove 41 contact the stationary limiting member 6, thereby limiting the maximum inward and outward opening angles of the movable page 2 (e.g., both 90 degrees), thus achieving precise limiting and preventing the door from opening excessively and colliding with the wall or other objects.

[0031] To enable adjustable limiting angles, multiple threaded holes 32 (not shown in the figure) can be formed along an arc path on the rotating base 3 corresponding to the trajectory of the limiting groove 41. Users can selectively install one or two limiting elements 6 in different threaded holes 32 as needed, thereby flexibly setting the limiting points of the door leaf. For example, installing a limiting element in only one threaded hole achieves unidirectional limiting, while installing limiting elements in two spaced-apart threaded holes changes the total limiting range.

[0032] Please see Figure 4 The structure of this embodiment offers significant waterproofing advantages. Since both the rotating seat 3 and the rotating block 4 protrude inwards from the hinge and cooperate with each other, the overall rotation center of the hinge is offset from the clamping plane of the fixed leaf 1 and the movable leaf 2. This naturally creates sufficient accommodating space between the edge of the movable leaf 2 (glass door 92) and the rotating seat 3. Therefore, the sealing strip 93 installed on the edge of the glass door 92 does not need to be cut as in the prior art when passing through the hinge area, maintaining its physical continuity. When the door is closed, the continuous sealing strip 93 can tightly adhere to the fixed glass panel 91 or wall, greatly improving the overall waterproofing performance of the shower enclosure and effectively solving the leakage problem caused by interrupted sealing strips in the prior art.

[0033] To further optimize the user experience and structural strength, this embodiment may also include the following improvements:

[0034] The rotating block 4 can be designed as a detachable connection to the movable page 2. For example, it can be connected by screws or other fasteners, rather than being a single piece. This design facilitates manufacturing, assembly, or individual replacement of the rotating block after wear, reducing maintenance costs.

[0035] On a hinge, at least two rotating blocks 4 can be arranged vertically at intervals along the end of the movable leaf 2, and at least two corresponding rotating grooves 31 can be provided on the rotating seat 3. This double (multi) fulcrum design makes the force distribution on the hinge more uniform, the rotation process more stable, and significantly enhances the load-bearing capacity of the glass door leaf, making it especially suitable for larger or heavier glass doors.

[0036] To make the rotation smoother, the bottom of the rotating groove 31 and the end of the rotating block 4 that contacts the bottom of the groove can be designed as a smooth arc-shaped contact surface.

[0037] To achieve better fit and visual effect when closed, the ends of the fixed page 1 and the movable page 2 can be designed with matching arcs, such as one being a convex arc and the other a concave arc.

[0038] Work process summary: During installation, the fixed page 1 and the movable page 2 are clamped to the fixed glass 91 and the glass door 92 respectively by the first and second clamping components. The opening angle is preset by inserting the limiting member 6 into the specific threaded hole 32 of the rotating seat 3. In use, the glass door 92 can rotate freely inward or outward around the rotating shaft 5. When it rotates to the preset maximum angle, the end of the limiting groove 41 on the rotating block 4 abuts against the limiting member 6, thereby being reliably stopped. The continuous sealing strip 93 ensures excellent water tightness in the closed state.

[0039] In summary, this utility model, through its unique rotation and clamping structure, and by utilizing an offset rotation design to reserve continuous space for the waterproof strip, while also setting up a reliable limiting mechanism, effectively overcomes the defects of existing technologies such as complex installation, easy leakage, and unreliable limiting, and has high practical value.
