Description

Technical Field

[0001] This utility model relates to a hardware hinge, specifically a cup-in-cup buffer type hardware hinge. Background Technology

[0002] With the increasing demands for hinge performance in modern furniture, doors, windows, and various home appliances, especially in terms of user comfort and durability, traditional hinge structures are gradually failing to meet market needs. To improve hinge comfort and extend their lifespan, damping hinges have emerged. Damping hinges primarily achieve smooth buffering during hinge opening and closing by incorporating damping devices within the hinge structure. This effectively prevents the impact and noise generated when the hinge closes rapidly, thus significantly enhancing the user experience.

[0003] However, common soft-close hinges in existing technology typically mount the damping device inside the hinge arm. While this design effectively achieves the damping function, it also has some significant drawbacks, mainly in the following aspects:

[0004] 1. Large hinge arm size: Because the damping device is installed inside the hinge arm, the size of the hinge arm is usually significantly increased. This not only makes the hinge arm bulky, but may also restrict its installation in some confined spaces, affecting its flexibility and adjustability.

[0005] 2. Impact on Appearance Design: Increased hinge arm size directly affects the aesthetics of the hinge, especially in home furnishings and furniture products where appearance is highly valued. Overly large hinge arms can appear bulky and detract from the overall sophistication. This traditional design is clearly less than ideal for the refined and minimalist trends in modern home design.

[0006] Therefore, existing buffer hardware hinges have drawbacks such as bulky hinge arms, inconvenient installation, and poor aesthetics, and it is necessary to make further improvements to them. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a cup-type buffer hinge that is simple in structure, easy to use, and achieves a cushioning effect while making the hinge more compact and aesthetically pleasing.

[0008] The purpose of this utility model is achieved in the following way: a cup-type buffered hardware hinge, which includes a hinge cup and a hinge arm. The hinge cup and the hinge arm are hinged together by an upper connecting rod and a lower connecting rod. The upper connecting rod and the lower connecting rod swing relative to the hinge cup and the hinge arm to realize the opening and closing of the hinge. The upper connecting rod is provided with a drive tooth, which is set off from the hinge point between the upper connecting rod and the hinge cup. A sliding plate is slidably installed in the hinge cup. The sliding plate has a drive groove opened at the position corresponding to the drive tooth. When the upper connecting rod swings, it drives the drive tooth to mesh with the drive groove, thereby driving the sliding plate to slide in the hinge cup.

[0009] A damper is also installed on the hinge cup. The damper is connected to the skateboard and acts as a damper to control the speed of the skateboard.

[0010] Furthermore, the drive teeth are provided in a plurality of positions, which are arranged in a circular pattern around the hinge point of the upper connecting rod.

[0011] Furthermore: the upper connecting rod is provided with a first hinge lug and a second hinge lug, and a hinge hole is provided through the first hinge lug and the second hinge lug, through which the upper hinge shaft passes and is hinged to the hinge cup.

[0012] Furthermore, the drive teeth are disposed on the outer contour of the first hinge ear.

[0013] Furthermore, an arc-shaped pressure plate is provided on the outer contour of the second hinge ear, and correspondingly, a limit plate is provided on the slide plate. The limit plate slides below the arc-shaped pressure plate to limit the upward movement of the slide plate.

[0014] Furthermore, a guide plate is also provided inside the hinge cup, which covers the bottom of the inner cup of the hinge cup. A limiting groove is provided in the upper end face of the guide plate, and the slide plate slides within the limiting groove.

[0015] Furthermore, the end of the guide plate is also provided with a locking tongue plate, which is inserted into the locking groove of the hinge cup side wall for fixation.

[0016] Furthermore, a spring is also provided between the slide plate and the hinge cup, and the spring pushes the slide plate to always slide away from the drive tooth.

[0017] Furthermore: the side wall of the hinge cup is recessed inward to form a receiving groove, and a cover plate covers the outside of the hinge cup. The cover plate and the receiving groove together form an installation area, and the damper is installed in this installation area.

[0018] Furthermore: the end face of the receiving groove is provided with a clearance groove through the side wall of the hinge cup, a connecting plate extends outward on the sliding plate, the connecting plate extends into the clearance groove, and the piston rod of the damper extends into the clearance groove and connects with the connecting plate.

[0019] The beneficial effects of this utility model are: 1. Simple structure, low production cost, and improved market competitiveness.

[0020] 2. This invention places the damper on one side of the hinge cup, instead of installing the damping device inside the hinge arm as in traditional designs. The biggest advantage of this design is that it effectively reduces the size of the hinge arm, making it more compact and streamlined, avoiding the problem of excessively large hinge arms caused by the space occupied by the damping device in existing technologies. The reduction in the size of the hinge arm not only improves the overall flexibility of the hinge but also makes the hinge installation easier, especially in situations with limited installation space.

[0021] 3. By moving the buffer device inside the hinge cup, the volume of the hinge arm is reduced, making the entire hinge system simpler and more streamlined. The simplified design of the hinge arm effectively avoids the problem of bulky hinge arms in traditional hinges affecting the overall aesthetics, making the hinge neater and more refined after installation, meeting the aesthetic requirements of modern home design.

[0022] 4. The hinge structure of this utility model can provide a cushioning effect comparable to that of traditional designs without increasing the size of the hinge cup. At the same time, this design makes the installation of the hinge and the selection of accessories more flexible, especially in situations where installation space is strictly limited, it can better exert the function of the hinge and make the most of the limited space.

[0023] 5. Because this invention optimizes the structural relationship between the hinge cup and the hinge arm, and reduces the complex mechanical structure inside the hinge arm, it not only improves the production efficiency of the hinge but also reduces manufacturing and maintenance costs. The simplified structure reduces the precision requirements required in the production process, thereby reducing manufacturing costs. Furthermore, due to the reduced size of the hinge arm, wear and maintenance costs during long-term use of the hinge are effectively controlled.

[0024] 6. This utility model effectively achieves smooth buffering during the opening and closing of the hinge through the rationally designed drive teeth and sliding plate, as well as the function of the damper. Compared with traditional technology, the buffering effect of this utility model is more stable, which can effectively prevent the impact force and noise generated by rapid closing, extend the service life of the hinge, and improve the comfort of use.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings. A cup-type buffered hardware hinge includes a hinge cup 1 and a hinge arm 2. The hinge cup 1 and the hinge arm 2 are hinged together by an upper connecting rod 3 and a lower connecting rod 4. The upper connecting rod 3 and the lower connecting rod 4 swing relative to the hinge cup 1 and the hinge arm 2 to realize the opening and closing of the hinge. The upper connecting rod 3 is provided with a drive tooth 31, which is offset from the hinge point between the upper connecting rod 3 and the hinge cup 1. A sliding plate 5 is slidably installed in the hinge cup 1. The sliding plate 5 has a drive groove 51 corresponding to the position of the drive tooth 31. When the upper connecting rod 3 swings, it drives the drive tooth 31 to engage with the drive groove 51, thereby driving the sliding plate 5 to slide in the hinge cup 1.

[0031] The hinge cup 1 is also equipped with a damper 6, which is connected to the slide plate 5. The damper 6 acts as a damper for the movement speed of the slide plate 5.

[0032] In one embodiment, the drive teeth 31 are provided with a plurality of teeth, which are arranged in a circular pattern around the hinge point of the upper connecting rod 3.

[0033] In one embodiment, the upper connecting rod 3 is provided with a first hinge lug 32 and a second hinge lug 33, and a hinge hole 34 is provided through the first hinge lug 32 and the second hinge lug 33. The upper hinge shaft 35 passes through the hinge hole 34 and is hinged to the hinge cup 1.

[0034] In one embodiment, the drive tooth 31 is disposed on the outer contour of the first hinge ear 32.

[0035] In one embodiment, an arc-shaped pressure plate 36 is provided on the outer contour of the second hinge ear 33. Correspondingly, a limiting plate 52 is provided on the slide plate 5. The limiting plate 52 slides below the arc-shaped pressure plate 36 to limit the upward movement of the slide plate 5.

[0036] In one embodiment, a guide plate 7 is also provided inside the hinge cup 1. The guide plate 7 covers the bottom of the inner cup of the hinge cup 1. A limiting groove 71 is provided in the upper end face of the guide plate 7. The slide plate 5 slides within the limiting groove 71.

[0037] In one embodiment, the end of the guide plate 7 is further provided with a locking tongue plate 72, which is inserted into the locking groove 11 on the side wall of the hinge cup 1 and fixed.

[0038] In one embodiment, a spring 8 is also provided between the slide plate 5 and the hinge cup 1, and the spring 8 pushes the slide plate 5 to slide away from the drive tooth 31.

[0039] In one embodiment, the side wall of the hinge cup 1 is recessed inward to form a receiving groove 12, and a cover plate 13 covers the outside of the hinge cup 1. The cover plate 13 and the receiving groove 12 together form an installation area, and the damper 6 is installed in the installation area.

[0040] In one embodiment, the end face of the receiving groove 12 is provided with a clearance groove 14 through the side wall of the hinge cup 1, and a connecting plate 53 extends outward from the slide plate 5. The connecting plate 53 extends into the clearance groove 14, and the piston rod 61 of the damper 6 extends into the clearance groove 14 and connects with the connecting plate 53.

[0041] Working principle: In this invention, the hinge cup 1 and the hinge arm 2 are hinged together by an upper connecting rod 3 and a lower connecting rod 4. The upper connecting rod 3 and the lower connecting rod 4 swing relative to the hinge cup 1 and the hinge arm 2, thereby opening and closing the hinge. This swinging design allows the hinge to open and close smoothly, and the reasonable structural design avoids excessive friction, thus improving the service life of the hinge.

[0042] The upper connecting rod 3 is equipped with a drive tooth 31, which is offset from the hinge point between the hinge cup 1 and the upper connecting rod 3. When the upper connecting rod 3 swings, the drive tooth 31 drives the slide plate 5 to move. The slide plate 5 is located inside the hinge cup 1, and the slide plate 5 and the hinge cup 1 are engaged with each other through a drive groove 51. The swinging of the upper connecting rod 3, through the meshing between the drive tooth 31 and the slide plate 5, causes the slide plate to slide within the hinge cup. During the movement of the slide plate 5, the damper 6 is connected to the slide plate, playing a damping role in the movement of the slide plate, thereby providing a buffering effect on the hinge. By absorbing the impact force during the movement, the damper allows the hinge to smoothly transition during the closing process, effectively reducing noise and extending the service life of the hinge.

[0043] Furthermore, to ensure the stable movement of the slide plate 5 within the hinge cup 1, a guide plate 7 is provided inside the hinge cup 1. The guide plate is fixedly covered on the inner bottom of the hinge cup. The slide plate 5 cooperates with the guide plate through the limiting groove 71 to ensure that the movement direction of the slide plate is guided and to avoid jamming. When the slide plate slides within the limiting groove, it can stably bear the transmission of force, thereby achieving a smooth opening and closing process.

[0044] To ensure that the slide plate 5 can return to its normal position after the hinge opens and always slides away from the drive tooth 31, a spring 8 is placed between the slide plate and the hinge cup. The function of the spring is to push the slide plate away from the drive tooth through elasticity, ensuring the smooth return of the slide plate and pushing the damper to return to its original position, providing a buffer condition for the next closing of the hinge.

[0045] One key point to note is that, for the installation and fixation of the damper, a receiving groove 12 is designed on the side wall of the hinge cup. The receiving groove provides ample installation space for the damper while ensuring its fixation and stable operation. The receiving groove 12 and the cover plate 13 together form the installation area for the damper, effectively utilizing the space of the hinge cup and making the fixation and installation of the buffer more convenient and quick.

[0046] Compared to traditional technologies, the hinge arm's volume is significantly reduced because the buffer device of this invention is located inside the hinge cup. This not only makes the hinge arm more compact but also avoids the unsightly appearance caused by the excessive size of the hinge arm due to the installation of dampers in traditional designs. The hinge is cleaner after installation, and its appearance better meets the aesthetic and refined requirements of modern home furnishings and furniture products.

[0047] Furthermore, this invention, through the careful design of the drive teeth, sliding plate, and damper, ensures smooth buffering during the opening and closing process of the hinge, reduces the impact force caused by rapid closing, lowers noise, and thus extends the service life of the hinge. This design effectively solves the durability problem of traditional hinges in high-frequency use.

[0048] Furthermore, this invention incorporates a buffer device within the hinge cup and utilizes limited installation space through a rational layout. This design makes the hinge structure more compact, suitable for smaller, more delicate spaces, especially in space-constrained installation environments, effectively saving space without affecting the hinge's function. By reducing the complexity of the hinge arm's structure, the requirements for the hinge arm during production are lowered, thereby reducing manufacturing and assembly costs. Through optimized overall design, this invention also simplifies the hinge installation process, reduces maintenance difficulty, and further lowers overall costs.

[0049] In summary, the cup-in-cup buffer type hardware hinge of this utility model achieves a buffering effect while optimizing the structural design, making the hinge arm more compact and the appearance more refined. It also has high stability and durability in use, providing an effective solution for the improvement of hinge products on the market. Therefore, it can be widely promoted and used.
