Technical Field

[0001] This application relates to the field of hinge technology, and more particularly to an adjusting screw and a cup-shaped concealed hinge. Background Technology

[0002] A hinge typically includes a hinge cup, a top cover (arm body), and a base. To achieve relative vertical adjustment between the arm body and the base, they are usually connected by an adjusting screw. By turning the adjusting screw in different directions, the base moves up or down relative to the arm body. However, the inventors discovered the following problem with the existing technology: when adjusting the height between the top cover and the base using the adjusting screw, the components do not fit tightly, resulting in a poor user experience.

[0003] It should be noted that the above content is not necessarily prior art, nor is it intended to limit the scope of patent protection of this application. Summary of the Invention

[0004] This application provides an adjusting screw and a cup-shaped concealed hinge to solve or alleviate one or more of the technical problems mentioned above.

[0005] As one aspect of the embodiments of this application, this application provides an adjusting screw, including:

[0006] A nut, the top surface of which is provided with a rotating groove;

[0007] A screw rod is fixed to the bottom surface of the nut. The screw rod includes a first section, a second section, a third section, a fourth section, and a fifth section connected in sequence. The first section is close to the nut, and the outer periphery of the first section is provided with external threads.

[0008] The colloid is fitted around the outer periphery of the third segment;

[0009] A gasket is fitted around the outer periphery of the fourth segment;

[0010] In use, the outer periphery of the second segment, the top surface of the colloid, and the bottom surface of the first segment together form an annular groove, and the fifth segment is used to prevent the gasket and the colloid from detaching from the screw.

[0011] Optionally, the screw has a multi-step shape; wherein:

[0055] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. The application will now be described in detail with reference to the accompanying drawings and embodiments.

[0056] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0057] The following provides a definition of the terminology used in this application.

[0058] Cup hinges, also known as American-style damped concealed hinges, meet or exceed the relevant definitions, requirements, and inspection standards of the People's Republic of China Light Industry Standards QB / T1242-1991 and QBT2189-2013, and also meet or exceed the relevant definitions, requirements, and inspection standards of EU Standard 15570-2008.

[0059] To facilitate understanding of the technical solutions provided in the embodiments of this application by those skilled in the art, the following is combined with... Figure 1 and Figure 2 Explanation of the relevant technologies:

[0060] Cup-shaped concealed hinges, a common type of furniture hardware, typically consist of a hinge cup, connecting plate, top cover, and base. They are installed between lightweight cabinet doors and the door frame, allowing the door to rotate relative to the frame. During installation, the top cover is fixed to the base, but sometimes vertical adjustments are needed, which requires adjusting screws.

[0061] like Figure 1As shown, the adjusting screw A in the related technology is a single, integral rigid component. The inventors discovered that a certain gap T needs to be left between this adjusting screw A and the base c for insertion, but this results in some vertical looseness. Additionally, as... Figure 2 After adjusting screw A up and down, the angle between the adjusting screw A and the recessed space of the inclined base c is smaller than the mating size of the base c. Because adjusting screw A is a one-piece rigid component, when adjusting screw A and base c are inclined, adjusting screw A will be compressed and unable to automatically adjust and repair the fit with base c. This will cause rigid compression deformation between adjusting screw A and base c. When adjusting the eccentric pin a to move the top cover b left and right, it will be interfered with by the rigid tight fit resistance between adjusting screw A and base c. This may result in the eccentric pin being unable to be adjusted. This is both violent twisting and damage to the related mating parts, resulting in a poor user experience.

[0062] To address these issues, this application provides a novel hinge screw. Details are provided below.

[0063] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0064] Example 1

[0065] like Figures 3-8 As shown in the figure, an embodiment of this application provides an adjusting screw. The adjusting screw B may include: a nut 1, a screw 2, a rubber body 3, and a washer 4.

[0066] The top surface of the nut 1 is provided with a rotating groove 11.

[0067] The screw 2 is fixed to the bottom surface of the nut 1. The screw includes a first section 21, a second section 22, a third section 23, a fourth section 24, and a fifth section 25 connected in sequence. The first section 21 is close to the nut, and the outer periphery of the first section 21 is provided with external threads.

[0068] The colloid 3 is fitted around the outer periphery of the third segment 23.

[0069] Gasket 4 is fitted around the outer periphery of the fourth segment 24.

[0070] In use, the outer periphery of the second segment 22, the top surface of the colloid 3, and the bottom surface of the first segment 21 together form an annular groove 5, and the fifth segment 25 is used to prevent the gasket 4 and the colloid 3 from detaching from the screw 2.

[0071] like Figures 3-4As shown, the adjusting screw B can be composed of a nut 1, a screw 2, a colloid 3, and a washer 4. The nut 1 and the screw 2 form a T-shape. The inner hole of the colloid 3 fits over the third section 23 of the screw 2. The washer 4 fits over the fourth section 24. Additionally, the fifth section 25, where the washer 4 is exposed, can be riveted.

[0072] like Figure 5 and Figure 6 As shown, in use, the adjusting screw B is installed in the hinge and used to adjust the distance between the upper cover 200 and the mounting bracket 300 in the hinge. Specifically, the external thread of the first segment 21 engages with the internal thread of the upper cover 200, and the annular groove 5 is rotatably engaged in the adjusting hole of the mounting bracket 300. Through the relative rotation of the internal and external threads, the distance between the lower surface of the upper cover 200 and the upper surface of the mounting bracket 300 can be changed. This allows for adjustable positioning of the kitchen cabinet door.

[0073] like Figure 5 and Figure 6 As shown, the upper cover 200 and the disassembly bracket 300 are parallel. The adjusting screw B has adhesive 3, so the connection between the upper cover 200 and the disassembly bracket 300 is seamless and loose.

[0074] like Figure 7 and Figure 8 As shown, when the adjusting screw B is adjusted up and down, the adjusting screw B will tilt with the disassembly frame 300. Because the adjusting screw B has the colloid 3, when the adjusting screw B tilts with the disassembly frame 300, the colloid 3 will be compressed and automatically adjust and repair the tight fit with the disassembly frame 300. Adjusting the eccentric nail 100 will make the upper cover 200 move left and right without being affected by resistance.

[0075] Compared with the adjusting screw A in the related technology, the adjusting screw B provided in Embodiment 1 of this application has the following advantages: the connection between the upper cover 200 and the disassembly bracket 300 is more compact and seamless, and it will not cause resistance interference when the eccentric nail 100 adjusts the upper cover 200 to move left and right, bringing users a compact, comfortable and smooth adjustment experience.

[0076] In an optional embodiment, to further improve the cooperation effect of the components, the screw 2 has a multi-step shape; wherein:

[0077] The outer diameter of the first segment 21 is larger than the outer diameter of the second segment 22;

[0078] The outer diameter of the second segment 22 is larger than the outer diameter of the third segment 23;

[0079] The outer diameter of the third segment 23 is greater than the outer diameter of the fourth segment 24.

[0080] In an optional embodiment, in order to facilitate insertion into the adjustment hole of the disassembly frame 300 and to facilitate the fitting of the colloid 3 and the gasket 4, the fifth segment 25 is a frustum structure, wherein the bottom surface of the frustum structure is fixed to the bottom of the fourth segment 24.

[0081] In an optional embodiment, the outer diameter of the third segment 23 is adapted to the inner diameter of the colloid 3 to reduce loosening and make it more compact.

[0082] In an optional embodiment, the outer diameter of the fourth segment 24 is matched with the inner diameter of the gasket 4 to reduce loosening and achieve a more compact fit.

[0083] In an optional embodiment, in use, the fifth segment 25 deforms into a riveting structure, the outer diameter of which is larger than the inner diameter of the gasket 4. Under external impact, the fifth segment 25 deforms and extends radially, achieving a robust riveting connection.

[0084] In an optional embodiment, the colloid 3 is made of a soft material. The soft material further ensures a seamless connection and a tight fit.

[0085] Example 2

[0090] Adjusting screw B as described in Example 1;

[0091] The annular groove of the adjusting screw B is rotatably engaged with the first adjusting hole; the external thread of the adjusting screw B is screwed into the internal thread of the second adjusting hole; under the action of external force, the external thread and the internal thread rotate relative to each other, and this relative rotation causes the distance between the disassembly frame 300 and the upper cover 200 to change.

[0092] In an optional embodiment, the disassembly frame 300 includes: a base, a fixing plate, and an eccentric nail 100.

[0093] The base is fixed to the door or door frame;

[0094] A fixed plate is slidably positioned on the base;

[0095] An eccentric pin is used to adjust the relative displacement between the base and the fixing plate in a first direction.
