Description

Technical Field

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

[0002] Hinges are key components that connect door panels to door frames, enabling the door to rotate and open. They are widely used in glass doors. By using hinges to install glass door panels onto the door frame or another glass door panel, the glass door can rotate smoothly.

[0003] Various hinge structures for glass doors exist in the prior art. For example, a glass door hinge disclosed in Chinese Patent Publication No. CN102400622A mainly includes an upper hinge mechanism and a lower hinge mechanism. The upper hinge mechanism consists of an upper hinge panel, an upper buffer pad, an upper rubber ring, and an upper hinge cover plate connected by screws. The lower hinge mechanism has a similar structure, and the upper and lower mechanisms are rotated together by connecting components. Although this structure has a certain buffering effect, in actual installation, the hinge is often difficult to align precisely due to processing errors in the position of the openings on the glass door panel.

[0004] Currently, most hinge products lack effective adjustment functions. If there is a misalignment in the hole position during installation, it is often impossible to adjust, which not only increases the difficulty of installation but may also affect the overall usability and aesthetics of the glass door. Therefore, providing an adjustable hinge with position adjustment capabilities that can adapt to different installation errors has become a technical problem that needs to be solved in this field.

It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0019] 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.

[0020] Please refer to Figures 1-7 This embodiment discloses an adjustable hinge, including a first hinge plate 10, a second hinge plate 20, and a pivot assembly 30 connecting the first hinge plate 10 and the second hinge plate 20. The pivot assembly 30 includes a first hinge portion 31 connected to the first hinge plate 10, a second hinge portion 32 connected to the second hinge plate 20, a first bushing disposed in the first hinge portion 31, a second bushing disposed in the second hinge portion 32, and a pivot 33 passing through the first bushing and the second bushing. During installation, the pivot 33 passes through the two bushings in sequence to realize the rotatable connection between the first hinge plate 10 and the second hinge plate 20, allowing the glass door panel 60 to open and close smoothly around the pivot. This structure not only provides reliable rotational support but also facilitates assembly and maintenance. like Figure 1 and Figure 2 As shown, the first page 10 is provided with a first clamping assembly 40, which includes a first clamping block 41 and a lateral adjustment module 42. The first page 10 is provided with a lateral sliding groove 11. The lateral adjustment module 42 includes a slider 421 slidably disposed in the lateral sliding groove 11, a connector 422 connecting the slider 421 and the first clamping block 41, and an adjustment component 423 for driving the slider 421 to move. A first gap 401 for clamping the glass door panel 60 is formed between the first page 10 and the first clamping block 41. In specific installation, a hole is made in the first glass door panel 60, the first page 10 is pressed tightly against the glass door panel 60, so that the glass door panel 60 is embedded in the first gap 401, and then clamped and fixed by the first clamping assembly 40. If there is a lateral deviation in the opening position of the glass door panel 60, the slider 421 can be driven to move along the lateral slide groove 11 by the adjusting component 423. The slider 421 drives the first clamping block 41 to adjust its position laterally through the connecting component 422, thereby compensating for the installation error and ensuring that the hinge and the glass door panel 60 are accurately aligned and installed.

[0021] like Figure 1 and Figure 4 As shown, a second clamping assembly 50 is provided on the second leaf piece 20. The second clamping assembly 50 includes a second clamping block 51, an elastic pad 52, and a locking member 53. The elastic pad 52 is disposed between the second leaf piece 20 and the second clamping block 51. The locking member 53 locks the second clamping block 51 and the elastic pad 52 onto the second leaf piece 20, forming a second gap 501 between the second leaf piece 20 and the second clamping block 51 for clamping the glass door panel 60. During installation, a waist hole 61 is made in the second glass door panel 60, and the second leaf piece 20 is pressed tightly against the glass door panel 60, so that the glass door panel 60 is embedded in the second gap 501. Then, the second clamping assembly 50 is locked by the locking member 53 to achieve fixation. The elastic pad 52 is inserted into the waist hole 61. The setting of the elastic pad 52 can prevent the glass door panel 60 from directly contacting the metal locking member 53, providing cushioning protection. Finally, the relative rotation of the two glass door panels 60 is achieved by utilizing the rotation of the pivot assembly 30.

[0022] like Figure 5 and Figure 6As shown, the elastic pad 52 is elongated. A waist hole 61 is pre-drilled on the second glass door panel 60, and the elastic pad 52 is inserted into the waist hole 61. The elastic pad 52 includes a first mounting portion 521 adjacent to the first leaf 10 and a second mounting portion 522 away from the first leaf 10. The first mounting portion 521 has a first through hole 5211 and a first slot 5212 communicating with the first through hole 5211. The first slot 5212 divides the first mounting portion 521 into a first upper support portion. 5213 and the first lower abutment portion 5214; the second mounting portion 522 is provided with a second through hole 5221 and a second slot 5222 communicating with the second through hole 5221. The second slot 5222 divides the second mounting portion 522 into a second upper support portion 5223 and a second lower abutment portion 5224; the top end of the first upper support portion 5213 is lower than the top end of the second upper support portion 5223, that is: the thickness m of the second upper support portion 5223 is greater than the thickness n of the first upper support portion 5213.

[0023] During installation, the elastic pad 52 is fully embedded in the waist hole 61 of the glass door panel 60, and is connected to the second leaf 20 by the locking member 53 passing through the through holes of the second clamping block 51 and the elastic pad 52 in sequence. Since the end of the glass door panel 60 furthest from the second leaf 20 is suspended, meaning the far end bears greater weight, it is prone to tilting during installation. In this application, the thicker second upper support portion 5223 can generate greater elastic deformation under pressure, compensating for the tilting angle change caused by the sinking of the far end of the glass door panel 60; simultaneously, the first slot 5212 and the second slot 5222 enable the first upper support portion 5213 and the second upper support portion 5223 to have independent deformation capabilities, enhancing adaptability to uneven surfaces. This structure can automatically adjust the support height, effectively maintaining the levelness of the glass door panel 60 after installation, improving installation stability and service life.

[0024] like Figure 2 As shown, the connecting member 422 is a first screw fixed to the slider 421; the adjusting member 423 includes a second screw 4231 and a rotating part 4232 located at the end of the second screw 4231, and the slider 421 is provided with a first threaded hole that is threadedly engaged with the second screw 4231. During adjustment, the second screw 4231 is rotated by rotating the rotating part 4232, and the slider 421 is precisely moved along the transverse slide groove 11 by means of thread transmission, thereby achieving fine adjustment of the position of the first clamping block 41. This screw transmission method has high adjustment accuracy and stable and reliable operation.

[0025] Furthermore, the surface of the rotating part 4232 is provided with anti-slip texture or external teeth. This design increases friction during adjustment, prevents slippage, and can also be used with special tools to improve the convenience and efficiency of adjustment.

[0026] like Figure 7As shown, the first clamping block 41 has a second screw hole 411 that mates with the first screw. A first groove 412 communicating with the second screw hole 411 is formed on the side of the first clamping block 411 facing away from the first leaf 10. A first cover 413 is provided at the end of the first groove 412. The edge of the first cover 413 is provided with an elastic buckle, which engages with the inside of the first groove 412 through elastic deformation. The first groove 412 provides operating space for the installation tool, while the first cover 413 is dustproof and waterproof, and easy to disassemble and maintain. The elastic buckle structure makes installation and disassembly more convenient.

[0027] like Figure 7 As shown, the first clamping assembly 40 also includes a first gasket 43, a washer 44, and a second gasket 45 sleeved on the connector 422; the first gasket 43 abuts against the first leaf 10, the second gasket 45 abuts against the first clamping block 41, and the first gasket 43 is provided with a lateral adjustment hole 431 for the connector 422 to move laterally. The first gasket 43 and the second gasket 45 can effectively disperse the clamping force and avoid excessive local stress on the glass door panel 60; the washer 44 provides a sealing function, and the lateral adjustment hole 431 provides the necessary space for the movement of the connector 422 to ensure smooth adjustment.

[0028] like Figure 2 As shown, the first leaf 10 has a second groove 12 at the end facing away from the first clamping block 41 to expose the lateral adjustment module 42. A second cover 13 is provided at the end of the second groove 12, and the edge of the second cover 13 is provided with elastic buckles, which are engaged into the inside of the first groove 412 by elastic deformation. The second groove 12 facilitates adjustment, and the second cover 13 protects the internal structure, facilitates maintenance, and maintains the product's aesthetics.

[0029] like Figure 7 As shown, the second clamping assembly 50 also includes a third washer 54, a connecting sleeve 55, and a fourth washer 56 disposed within the second gap 501; the third washer 54 abuts against the second leaf 20, and the fourth washer 56 abuts against the second clamping block 51; the locking element 53 is a screw, and the connecting sleeve 55 is fixed to the second leaf 20 and threadedly connected to the screw. The third washer 54 and the fourth washer 56 can evenly distribute the locking force, reducing damage to the glass door panel 60, and the connecting sleeve 55 enhances the strength and durability of the threaded connection.

[0030] like Figure 7As shown, the second clamping block 51 has a third through hole 511 through which the locking member 53 passes. The end face of the second clamping block 51 has a third groove 512 communicating with the third through hole 511. A third cover 513 is provided at the end of the third groove 512. The edge of the third cover 513 has elastic buckles that engage with the inside of the third groove 512 through elastic deformation. The third groove 512 provides operating space for the installation tool, the third cover 513 serves a protective and aesthetic purpose, and the elastic buckle design facilitates disassembly and maintenance.
