Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically to a short-arm, thin-body hinge. Background Technology

[0002] Traditional hinges are widely used in household furniture such as cabinets, wardrobes, and bathroom vanities, as well as some light industrial cabinets. Their core function is to connect the cabinet door to the cabinet body, enabling the cabinet door to rotate and open flexibly and be positioned at different angles, thus meeting the daily opening and closing needs of the furniture.

[0003] like Figure 5 As shown, its typical structure includes components such as the arm, base, and hinge cup. While it can complete the basic connection task, it often adopts a long arm design to accommodate larger opening angles. Moreover, the arm and base are mostly separate assembly structures, which can only meet the basic usage requirements of traditional furniture. In the scenario of modern customized furniture pursuing lightness and refinement, such as small apartment light luxury style cabinets, built-in wardrobes, and minimalist style bathroom vanities, the long arm design of traditional hinges results in an excessively long overall hinge length. After installation, it is easy for it to protrude into the gap between the cabinet door and the cabinet body. At the same time, after the separate arm and base are assembled, the stress points are dispersed. Under the long-term weight of the cabinet door and the force of frequent opening and closing, problems such as loosening of the base and sagging of the cabinet door are likely to occur. It is difficult to adapt to the dual requirements of modern furniture for aesthetic refinement and structural stability. Utility Model Content

[0004] This invention provides a short-arm, thin-body hinge to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A short-arm, thin-body hinge includes an arm body base, a base plate at the bottom of the arm body base, a first adjusting screw threaded to one side of the surface of the arm body base, and a second adjusting screw disposed inside an elliptical hole on the surface of the arm body base.

[0007] A further improvement of this utility model is that: the short arm body is fixedly connected to the surface of the arm body seat, and a decorative cover is provided on the surface of the arm body seat.

[0008] A further improvement of this utility model is that: a hydraulic cylinder damping buffer assembly is provided inside the short arm body, and a U-shaped pin is inserted into the end of the short arm body.

[0009] A further improvement of this utility model is that: a hinge cup is rotatably connected to one end of the U-shaped pin, and a connecting piece is rotatably connected to the surface of the hinge cup.

[0010] A further improvement of this utility model is that one end of the connecting piece is rotatably connected to the end of the short arm body, and a torsion spring is rotatably connected inside the connecting piece.

[0011] A further improvement of this utility model is that: the lower end of the first adjusting screw is provided with an elliptical fixing block, the surface of the elliptical fixing block is inserted into the U-shaped hole on the surface of the substrate, and the lower end of the second adjusting screw is connected to the internal thread of the substrate.

[0012] A further improvement of the present invention is that the hydraulic cylinder damping buffer assembly includes a hydraulic cylinder sleeve and a buffer cylinder. The buffer cylinder is disposed inside the hydraulic cylinder sleeve, one end of the buffer cylinder overlaps with the inner wall of the short arm body, and the surface of the hydraulic cylinder sleeve is rotatably connected to the surface of the U-shaped pin.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] This utility model provides a short-arm, thin-body hinge. By integrating the hinge body and the short arm into a single unit, it replaces the traditional long arm and separate structure. The short arm significantly reduces the overall hinge length. A decorative cover on the arm body surface conceals the first and second adjusting screws, preventing them from protruding from the cabinet door and body gap after installation. This design is suitable for the slim profile requirements of small-apartment, light luxury style cabinets and minimalist bathroom vanities, enhancing the overall aesthetics of the furniture. Simultaneously, the base plate and arm body feature an enlarged and widened design. Combined with the fixing block at the lower end of the first adjusting screw and the double fixing of the second adjusting screw, the installation force-bearing area is increased, effectively distributing the weight of the cabinet door and the force generated by frequent opening and closing. The integrated arm body and short arm avoid the problem of force dispersion in separate structures, reducing the likelihood of base loosening and cabinet door sagging over long-term use. This meets the dual requirements of modern custom furniture for both aesthetic refinement and structural stability. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to embodiments:

[0022] Example 1, as Figures 1-5 As shown, this utility model provides a short-arm, thin-body hinge, including an arm body base 1, a base plate 2 at the bottom of the arm body base 1, a first adjusting screw 3 threadedly connected to one side of the surface of the arm body base 1, a second adjusting screw 4 inside the elliptical hole on the surface of the arm body base 1, a short arm body 5 fixedly connected to the surface of the arm body base 1, and a decorative cover 6 on the surface of the arm body base 1.

[0023] In this embodiment, the base plate 2 is first fixed to the preset position of the cabinet body, and then the position is calibrated by the first adjusting screw 3 and the second adjusting screw 4 on the surface of the arm body seat 1: the elliptical fixing block at the lower end of the first adjusting screw 3 is inserted into the U-shaped hole of the base plate 2, and the position of the arm body seat 1 can be adjusted laterally by rotating it; the second adjusting screw 4 is screwed into the interior of the base plate 2, and the height of the arm body seat 1 can be adjusted longitudinally. The dual adjustment ensures that the hinge is accurately aligned with the cabinet door and the cabinet body. At the same time, the enlarged and widened base plate 2 and the integrated arm body seat 1-short arm body 5 structure distribute the installation force and prevent loosening.

[0024] Example 2, as Figures 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, it includes an arm body base 1, a base plate 2 at the bottom of the arm body base 1, a first adjusting screw 3 threadedly connected to one side of the surface of the arm body base 1, a second adjusting screw 4 inside the elliptical hole on the surface of the arm body base 1, a short arm body 5 fixedly connected to the surface of the arm body base 1, a decorative cover 6 on the surface of the arm body base 1, a hydraulic cylinder damping buffer assembly 7 inside the short arm body 5, a U-shaped pin 8 inserted into the end of the short arm body 5, a hinge cup 9 rotatably connected to one end of the U-shaped pin 8, a connecting piece 10 rotatably connected to the surface of the hinge cup 9, one end of the connecting piece 10 rotatably connected to the end of the short arm body 5, and a torsion spring 11 rotatably connected inside the connecting piece 10.

[0025] In this embodiment, the hinge cup 9 is fixed to the cabinet door, and the arm body seat 1 is connected to the cabinet body. When the door is opened, the cabinet door drives the hinge cup 9 to rotate around the U-shaped pin 8. At the same time, the hinge cup 9 pulls the connecting piece 10. One end of the connecting piece 10 rotates around the end of the short arm body 5, and the other end moves synchronously with the hinge cup 9. During the process, the torsion spring 11 is twisted and stores energy to reserve kinetic energy for closing and resetting. When the door is closed, the torsion spring 11 releases its elastic force and pushes the connecting piece 10 in the opposite direction, driving the hinge cup 9 and the cabinet door to return to the correct position. The U-shaped pin 8 always provides stable rotational support for the hinge cup 9 to prevent deviation.

[0026] Example 3, as Figures 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, it includes an arm body base 1, a base plate 2 at the bottom of the arm body base 1, a first adjusting screw 3 threadedly connected to one side of the surface of the arm body base 1, a second adjusting screw 4 disposed inside the elliptical hole on the surface of the arm body base 1, a short arm body 5 fixedly connected to the surface of the arm body base 1, a decorative cover 6 disposed on the surface of the arm body base 1, an elliptical fixing block disposed at the lower end of the first adjusting screw 3, the surface of the elliptical fixing block being inserted into the U-shaped hole on the surface of the base plate 2, the lower end of the second adjusting screw 4 being threadedly connected to the inside of the base plate 2, and a hydraulic cylinder damping buffer assembly 7 including a hydraulic cylinder sleeve and a buffer hydraulic cylinder, the buffer hydraulic cylinder being disposed inside the hydraulic cylinder sleeve, one end of the buffer hydraulic cylinder overlapping the inner wall of the short arm body 5, and the surface of the hydraulic cylinder sleeve being rotatably connected to the surface of the U-shaped pin 8.

[0027] In this embodiment, the buffer cylinder inside the short arm body 5 slides within the cylinder sleeve, and the hydraulic damping counteracts the impact force of closing the door, preventing the cabinet door from colliding with the cabinet body. In addition, the decorative cover 6 on the surface of the arm body seat 1 covers the adjusting screws, and together with the thin design of the short arm body 5, it avoids the hinge protruding from the furniture gap, taking into account both function and exquisite appearance, and fully adapting to the usage needs of modern custom furniture.

[0028] The working principle of this short-arm, thin-body hinge will be explained in detail below.

[0029] like Figures 1-5As shown, during installation, first fix the base plate 2 to the preset position on the cabinet body, and then calibrate the position using the first adjusting screw 3 and the second adjusting screw 4 on the surface of the arm body seat 1: the elliptical fixing block at the lower end of the first adjusting screw 3 is inserted into the U-shaped hole of the base plate 2, and rotating it can make a slight horizontal adjustment to the position of the arm body seat 1; the second adjusting screw 4 is screwed into the interior of the base plate 2, and the height of the arm body seat 1 can be adjusted vertically. The dual adjustment ensures that the hinge is precisely aligned with the cabinet door and the cabinet body. At the same time, the enlarged and widened base plate 2 and the integrated arm body seat 1-short arm body 5 structure distribute the installation force and prevent loosening. After the hinge is assembled, the hinge cup 9 is fixed to the cabinet door, and the arm body seat 1 is connected to the cabinet body. When the door is opened, the cabinet door drives the hinge cup 9 to rotate around the U-shaped pin 8, and the hinge cup 9 pulls the connecting... The connecting piece 10 rotates at one end around the end of the short arm body 5, while the other end moves synchronously with the hinge cup 9. During this process, the torsion spring 11 is twisted and stores energy to prepare for the door to return to its original position when the door is closed. When the door is closed, the torsion spring 11 releases its elasticity and pushes the connecting piece 10 in the opposite direction, causing the hinge cup 9 and the cabinet door to return to their original positions. The U-shaped pin 8 always provides stable rotational support for the hinge cup 9 to prevent it from shifting. In the later stage of closing, the buffer cylinder inside the short arm body 5 slides in the cylinder sleeve, and the hydraulic damping offsets the impact force of closing the door to prevent the cabinet door from colliding with the cabinet body. In addition, the decorative cover 6 on the surface of the arm body seat 1 covers the adjusting screw. Combined with the thin design of the short arm body 5, it prevents the hinge from protruding from the furniture gap, taking into account both function and exquisite appearance, and adapting to the usage needs of modern custom furniture throughout the process.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
