Description

Technical Field

[0001] The invention relates to a hardware hinge, in particular to an in-cup buffer type hardware hinge. Background Art

[0002] With the increasing requirements for hinge performance in modern furniture, doors and windows, and various home appliances, especially the requirements for comfort and durability, the traditional hinge structure has gradually failed to meet the market demand. In order to improve the comfort of hinges and extend their service life, buffering hardware hinges came into being. Buffering hardware hinges mainly achieve smooth buffering during the opening and closing of hinges by setting a damping device in the hinge structure, effectively preventing the impact force and noise generated when the hinge is quickly closed, thereby greatly improving the user experience.

[0003] However, the common buffer hardware hinges in the prior art usually install the damping device inside the hinge arm. Although this design can effectively achieve the buffering function, it also has some significant disadvantages, which are mainly reflected in the following aspects: 1. The hinge arm is bulky: Since the damping device is installed inside the hinge arm, the volume of the hinge arm usually increases significantly. This not only makes the hinge arm bulky, but also may be restricted when installed in some narrow spaces, affecting the flexibility and adjustability of use.

[0004] 2. Affecting the appearance design: The increase in the size of the hinge arm directly affects the aesthetics of the hinge, especially in some home furnishings and furniture products that have high requirements for appearance design. An oversized hinge arm will appear bulky and affect the exquisiteness of the overall design. For the trend of refinement and simplicity in modern home design, this traditional design is obviously not ideal.

[0005] Therefore, the buffer hardware hinge in the prior art has the disadvantages of bulky hinge arms, inconvenient installation, poor aesthetics, etc., and it is necessary to make further improvements thereto. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a cup-buffered hardware hinge which is simple in structure, easy to use, and has a more compact size and a more beautiful appearance while satisfying the buffering effect.

[0007] The object of the present invention is achieved in the following manner: a cup-buffered hardware hinge, which includes a hinge cup and a hinge arm, the hinge cup and the hinge arm are hinged 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 driving tooth, the driving tooth is arranged away from the hinge point between the upper connecting rod and the hinge cup, a slide plate is slidably installed in the hinge cup, a driving groove is provided on the slide plate corresponding to the position of the driving tooth, when the upper connecting rod swings, the driving tooth is driven to mesh with the driving groove, thereby driving the slide plate to slide in the hinge cup; A damper is also installed on the hinge cup, and the damper is connected to the slide plate, and the damper plays a damping role on the movement speed of the slide plate.

[0008] Furthermore: the driving teeth are provided in a plurality and are distributed in a circle around the hinge point of the upper connecting rod.

[0009] Furthermore, the upper connecting rod is provided with a first hinge ear and a second hinge ear, and a hinge hole is provided through the first hinge ear and the second hinge ear, and the upper hinge shaft passes through the hinge hole to be hinged with the hinge cup.

[0010] Furthermore: the driving tooth is arranged on the outer contour of the first hinged ear.

[0011] Furthermore: an arc-shaped pressure plate is arranged on the outer contour of the second hinged ear, and correspondingly, a limit plate is arranged on the slide plate, and the limit plate slides below the arc-shaped pressure plate to limit the upward movement of the slide plate.

[0012] Furthermore: a guide plate is also arranged in the hinge cup, the guide plate covers the inner cup bottom of the hinge cup, the upper end surface of the guide plate is concavely provided with a limiting groove, and the slide plate slides in the limiting groove.

[0013] Furthermore: a locking tongue plate is also provided at the end of the guide plate, and the locking tongue plate is inserted into a locking groove of the side wall of the hinge cup and fixed.

[0014] Furthermore, a spring is arranged between the slide plate and the hinge cup, and the spring pushes the slide plate to always slide toward a side away from the driving teeth.

[0015] Furthermore: the side wall of the hinge cup is concavely provided with a receiving groove inwardly of the cup, and a cover plate is covered on the outside of the hinge cup. The cover plate and the receiving groove together form an installation area, and the damper is installed in the installation area.

[0016] Furthermore: the end surface of the accommodating groove passes through the side wall of the hinge cup to be provided with an air avoidance groove, a connecting plate extends outwardly from the slide plate, the connecting plate extends into the air avoidance groove, and the piston rod of the damper extends into the air avoidance groove and is connected to the connecting plate.

[0017] The beneficial effects of the present invention are: 1. Simple structure, low production cost and improved market competitiveness.

[0018] 2. The damper is arranged on one side of the hinge cup in the present invention, instead of installing the damping device inside the hinge arm as in the traditional design. The biggest advantage of this design is that it effectively reduces the volume of the hinge arm, making the hinge arm more compact and streamlined, and avoiding the problem of the hinge arm being too large in size due to the space occupied by the damping device in the prior art. The reduction in the volume of the hinge arm not only improves the overall flexibility of the hinge, but also makes the installation of the hinge easier, especially in occasions where the installation space is limited.

[0019] 3. Since the buffer device is moved into the hinge cup, the volume of the hinge arm is reduced, making the entire hinge system more concise and streamlined. The simplified design of the hinge arm effectively avoids the problem of the bulky hinge arm in the traditional hinge affecting the overall aesthetics, making the hinge more neat and delicate after installation, which meets the aesthetic requirements of modern home design.

[0020] 4. The hinge structure of the present invention can provide a buffering effect equivalent to that of the traditional design 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 occasions with strict restrictions on the installation space, it can better play the function of the hinge and maximize the use of limited space.

[0021] 5. Since the present 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 the manufacturing and maintenance costs. The simplified structure reduces the precision requirements required in the production process, and the manufacturing cost is reduced accordingly. In addition, since the volume of the hinge arm is reduced, the wear and maintenance costs of the hinge in long-term use are also effectively controlled.

[0022] 6. The present invention effectively achieves stable buffering during the opening and closing of the hinge through the rationally designed driving teeth and the slide plate, as well as the function of the damper. Compared with the traditional technology, the buffering effect of the present invention is more stable, which can effectively prevent the impact force and noise generated by rapid closing, prolong the service life of the hinge and improve the comfort of use.

[0028] The present invention is further described in detail below with reference to the accompanying drawings. A cup-buffered hardware hinge includes a hinge cup 1 and a hinge arm 2. The hinge cup 1 and the hinge arm 2 are hinged via 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 driving tooth 31. The driving tooth 31 is arranged away from the hinge point between the upper connecting rod 3 and the hinge cup 1. A slide plate 5 is slidably installed in the hinge cup 1. The slide plate 5 is provided with a driving groove 51 corresponding to the position of the driving tooth 31. When the upper connecting rod 3 swings, the driving tooth 31 is driven to engage with the driving groove 51, thereby driving the slide plate 5 to slide in the hinge cup 1. The hinge cup 1 is also provided with a damper 6 , which is connected to the slide plate 5 , and plays a role in damping the movement speed of the slide plate 5 .

[0029] In one embodiment, a plurality of driving teeth 31 are provided, which are distributed in a circle around the hinge point of the upper connecting rod 3 .

[0030] In one embodiment, the upper connecting rod 3 is provided with a first hinge ear 32 and a second hinge ear 33 , and a hinge hole 34 is provided through the first hinge ear 32 and the second hinge ear 33 , and the upper hinge shaft 35 passes through the hinge hole 34 to be hinged to the hinge cup 1 .

[0031] In one embodiment, the driving tooth 31 is arranged on the outer contour of the first hinge ear 32 .

[0032] In one embodiment, an arc-shaped pressure plate 36 is provided on the outer contour of the second hinged ear 33 , and correspondingly, a limit plate 52 is provided on the slide plate 5 , and the limit plate 52 slides under the arc-shaped pressure plate 36 to limit the upward movement of the slide plate 5 .

[0033] In one embodiment, a guide plate 7 is further provided in the hinge cup 1 , and the guide plate 7 covers the inner cup bottom of the hinge cup 1 . A limiting groove 71 is concavely provided on the upper end surface of the guide plate 7 , and the slide plate 5 slides in the limiting groove 71 .

[0034] In one of the embodiments, a locking tongue plate 72 is further provided at the end of the guide plate 7 , and the locking tongue plate 72 is inserted into the locking groove 11 of the side wall of the hinge cup 1 and fixed.

[0035] In one embodiment, a spring 8 is further provided between the slide plate 5 and the hinge cup 1 , and the spring 8 pushes the slide plate 5 to always slide toward a side away from the driving tooth 31 .

[0036] In one embodiment, the side wall of the hinge cup 1 is concavely provided with a receiving groove 12 inwardly of the cup, and the hinge cup 1 is covered with a cover plate 13. The cover plate 13 and the receiving groove 12 together form an installation area, and the damper 6 is installed in the installation area.

[0037] In one of the embodiments, the end face of the accommodating groove 12 is provided with a space-avoiding groove 14 through the side wall of the hinge cup 1, a connecting plate 53 extends outward from the slide plate 5, the connecting plate 53 extends into the space-avoiding groove 14, and the piston rod 61 of the damper 6 extends into the space-avoiding groove 14 and is connected to the connecting plate 53.

[0038] Working principle: In the present invention, the hinge cup 1 and the hinge arm 2 are hinged by the upper connecting rod 3 and the 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 realizing the opening and closing of the hinge. This swinging design allows the hinge to open and close smoothly, and through reasonable structural design, excessive friction is avoided, thereby increasing the service life of the hinge.

[0039] Among them, the upper connecting rod 3 is provided with a driving tooth 31, which is set away from the hinge point between the hinge cup 1 and the upper connecting rod 3. When the upper connecting rod 3 swings, the driving 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 cooperate with each other through the driving groove 51. The swing of the upper connecting rod 3 causes the slide plate to slide inside the hinge cup through the meshing between the driving tooth 31 and the slide plate 5. During the movement of the slide plate 5, the damper 6 is connected to the slide plate to damp the movement of the slide plate, thereby achieving a buffering effect on the hinge. The damper absorbs the impact force during the movement, so that the hinge transitions smoothly during the closing process, effectively reducing noise and extending the service life of the hinge.

[0040] Furthermore, in order to ensure the stable movement of the slide plate 5 in the hinge cup 1, a guide plate 7 is provided in the hinge cup 1, and 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 limit groove 71 to ensure that the movement direction of the slide plate is guided to avoid jamming. When the slide plate slides in the limit groove, it can stably withstand the transmission of force, thereby achieving a smooth opening and closing process.

[0041] In order to ensure that the slide plate 5 can be normally reset after the hinge is opened and always keep sliding away from the driving tooth 31, a spring 8 is arranged between the slide plate and the hinge cup. The function of the spring is to push the slide plate away from the driving tooth through elastic force, ensure the smooth reset of the slide plate, and push the damper to reset, providing a buffer condition for the next closing of the hinge.

[0042] It is important to note that in order to install and fix the damper, a receiving groove 12 is designed on the side wall of the hinge cup in this case, which provides sufficient installation space for the damper and ensures the fixation and stable operation of the damper. The receiving groove 12 and the cover plate 13 together form an installation area for the damper, which effectively utilizes the space of the hinge cup and makes the fixation and installation of the buffer more convenient and quick.

[0043] Compared with the conventional technology, the volume of the hinge arm can be greatly reduced because the buffer device of the present invention is arranged in the hinge cup. This not only makes the hinge arm more compact, but also avoids the defect that the hinge arm in the conventional design becomes too large due to the installation of the damper, resulting in an unsightly appearance. The hinge is neater after installation, and the appearance is more in line with the requirements of modern home furnishings and furniture products for beauty and refinement.

[0044] In addition, the invention ensures the smooth buffering of the hinge during the opening and closing process through the well-designed driving teeth, slide plate and damper, reduces the impact force caused by rapid closing, reduces noise, and thus prolongs the service life of the hinge. This design effectively solves the durability problem of traditional hinges in high-frequency use.

[0045] In addition, the present invention sets the buffer device in the hinge cup and utilizes the limited installation space through reasonable layout. This design makes the structure of the hinge more compact and suitable for smaller and more delicate spaces. Especially in installation environments with limited space, it can effectively save space without affecting the function of the hinge. Since the complex structure of the hinge arm is reduced, the requirements for the hinge arm in the production process are reduced, thereby reducing the manufacturing and assembly costs. By optimizing the overall design, the present invention also simplifies the installation process of the hinge, reduces the difficulty of maintenance, and further reduces the overall cost.

[0046] In summary, the in-cup buffering hardware hinge of the present invention optimizes the structural design while achieving the buffering effect, making the hinge arm more compact and the appearance more refined, and having higher stability and durability in use, providing an effective solution for the improvement of hinge products on the market, and can therefore be widely promoted and used.

[0047] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims created by the present invention.
