Description

Technical Field

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

[0002] In modern daily life, hardware hinges are widely used in the connection and opening and closing mechanisms of various containers, furniture and electronic devices. Especially in daily necessities such as cups, the performance of the hinge directly affects the user experience and durability of the product. In order to improve the comfort of the hinge and extend its service life, buffering hardware hinges came into being. It mainly achieves smooth buffering during the opening and closing of the hinge by setting a damping device to prevent the impact and noise caused by rapid closing.

[0003] The buffering hardware hinges in the prior art usually set the damping device inside the hinge cup or inside the hinge arm. Although this design can achieve a certain degree of buffering effect, it still has the following shortcomings: 1. Small internal space: The space inside the hinge cup and hinge arm is usually limited, which limits the installation position of the damping device. This small space requires the structure of the damping device to be highly compact to fit the limited installation space, thereby increasing the complexity and cost of manufacturing.

[0004] 2. High manufacturing precision requirements: Due to the limited internal space, each component of the damping device needs to be precisely manufactured to ensure its normal operation in a small space. This not only increases the manufacturing difficulty, but also increases the defective rate in the production process, affecting the consistency and reliability of the product.

[0005] 3. Limited damper volume: The small internal space limits the volume of the damper, making it difficult for its damping effect to meet the expected requirements. Smaller dampers are insufficient in providing sufficient buffering force, resulting in unsatisfactory buffering effect when the hinge is closed, and unable to effectively reduce impact and noise.

[0006] 4. Limited service life: Due to the small size of the damper, the moving parts inside it are subjected to greater stress, which is prone to accelerated wear. In addition, poor heat dissipation in a small space may also affect the performance stability of the damper and further shorten its service life. Therefore, it is necessary to make further improvements to it. Summary of the invention

[0007] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a cup-shaped buffer hardware hinge with simple structure, easy use, and effective buffering and damping effect in a limited space, while simplifying the manufacturing process and improving product durability.

[0008] The object of the present invention is achieved by the following method: a cup-outer buffer hardware hinge, which comprises a hinge cup and a hinge arm, wherein the hinge cup and the hinge arm are hingedly connected through 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 respectively, thereby realizing the opening and closing of the hinge; A guide groove penetrating the body is provided at the bottom of the hinge cup, and the guide groove extends along the bottom of the hinge cup; The outer bottom of the hinge cup is covered with a driving plate; A slider is provided on the top of the driving plate, and the slider is slidably installed in the guide groove; A driving arm extends outwardly from one end of the upper connecting rod toward the hinge cup, and when the hinge is closed, the driving arm acts on the slider to push the slider to slide in the guide groove; A buffer is installed on the outer bottom of the hinge cup, and the piston rod or cylinder part of the buffer is connected to the drive plate. The buffer produces a damping effect on the movement of the drive plate, thereby achieving a damping effect when the hinge is closed.

[0009] Further: a mounting groove is provided at one end of the guide groove, and the mounting groove is communicated with the guide groove; The sliding block slides into the guiding groove through the installation groove, so that the sliding block slides from the installation groove into the guiding groove.

[0010] Furthermore: the width of the installation groove is set larger than the width of the guide groove, and the width of the sliding block is set larger than the guide groove and smaller than the width of the installation groove.

[0011] Furthermore: both sides of the sliding block are inwardly concave to form sliding grooves, and the sliding grooves are clamped on the two side surfaces of the guide groove to slide.

[0012] Furthermore: the installation groove and the guide groove are distributed in a "T" shape.

[0013] Furthermore, two of the mounting grooves and two of the guide grooves are provided, which are distributed on opposite sides at the bottom of the hinge cup.

[0014] Furthermore, guide plates are extended upwards on both sides of the driving plate, and the guide plates are arranged to cover the outside of the two side surfaces of the hinge cup.

[0015] Furthermore: in the guide plate, the inner side surface of any one of the guide plates is concave to form a clamping groove, and the buffer is clamped and fixed in the clamping groove.

[0016] Furthermore, a positioning column is extended outwardly from the side wall of the hinge cup, and the positioning column is supported on the end surface of the clamping groove and pressed against the tail of the buffer.

[0017] Furthermore: the buffer is a self-resetting compression type hydraulic buffer.

[0018] The beneficial effects of the present invention are: 1. Simple structure, low production cost and improved market competitiveness.

[0019] 2. The present invention installs the buffer on the outside of the hinge arm, and effectively utilizes the external space through the design of the guide groove and the driving plate, thereby avoiding the problem of limited internal space.

[0020] 3. The external buffer device makes the internal structure of the hinge cup and hinge arm more concise, reduces the number and complexity of internal parts, and improves the stability and reliability of the overall structure.

[0021] 4. Since the buffer is installed outside and is not limited by the internal space, a larger hydraulic buffer can be used to provide stronger damping force. This effectively improves the buffering effect of the hinge when closing, can better reduce impact and noise, and improve the user experience.

[0022] 5. Through the design of guide grooves and sliders, the movement path of the buffer is more optimized, ensuring the stable transmission of damping force and improving the overall buffering performance.

[0023] 6. Since the buffer device is installed outside, it is not necessary to perform high-precision assembly in a narrow internal space, which reduces the requirements for manufacturing tolerances. This not only simplifies the manufacturing process, but also reduces the defective rate caused by insufficient precision during the production process and reduces production costs.

[0030] The present invention is further described in detail below with reference to the accompanying drawings. A cup-outer buffer hardware hinge comprises a hinge cup 2 and a hinge arm 1, wherein the hinge cup 2 and the hinge arm 1 are hingedly connected via an upper connecting rod 3 and a lower connecting rod 31; the upper connecting rod 3 and the lower connecting rod 31 swing relative to the hinge cup 2 and the hinge arm 1, respectively, so as to realize the opening and closing of the hinge; a guide groove 21 penetrating through the body is provided at the bottom of the hinge cup 2, and the guide groove 21 extends along the bottom of the hinge cup 2; The outer bottom of the hinge cup 2 is covered with a driving plate 4; A slider 41 is provided on the top of the driving plate 4, and the slider 41 is slidably installed in the guide groove 21; A driving arm 32 extends outwardly from one end of the upper connecting rod 3 toward the hinge cup 2. When the hinge is closed, the driving arm 32 acts on the slider 41 to push the slider 41 to slide in the guide groove 21. A buffer 5 is installed on the outer bottom of the hinge cup 2. The piston rod or cylinder part of the buffer 5 is connected to the drive plate 4. The buffer 5 produces a damping effect on the movement of the drive plate 4, thereby achieving a damping effect when the hinge is closed.

[0031] In one embodiment: a mounting groove 22 is provided at one end of the guide groove 21, and the mounting groove 22 is communicated with the guide groove 21; The sliding block 41 slides into the guiding groove 21 through the mounting groove 22 , so that the sliding block 41 slides from the mounting groove 22 into the guiding groove 21 .

[0032] In one embodiment, the width of the installation groove 22 is larger than the width of the guide groove 21 , and the width of the slider 41 is larger than the guide groove 21 and smaller than the width of the installation groove 22 .

[0033] In one embodiment, two sides of the slider 41 are concave to form sliding grooves 42 , and the sliding grooves 42 are clamped on the two side surfaces of the guide groove 21 to slide.

[0034] In one embodiment, the mounting groove 22 and the guide groove 21 are arranged in a T-shape.

[0035] In one embodiment, two mounting grooves 22 and two guide grooves 21 are provided, which are distributed on opposite sides at the bottom of the hinge cup 2 .

[0036] In one embodiment, guide plates 43 extend upwardly from both sides of the driving plate 4 , and the guide plates 43 are arranged to cover the outside of the two side surfaces of the hinge cup 2 .

[0037] In one of the embodiments: in the guide plate 43 , the inner side surface of any one of the guide plates 43 is concave to form a clamping groove 44 , and the buffer 5 is clamped and fixed in the clamping groove 44 .

[0038] In one embodiment, a positioning column 23 is extended outward from the side wall of the hinge cup 2 , and the positioning column 23 is supported on the end surface of the clamping groove 44 and pressed against the tail of the buffer 5 .

[0039] In one embodiment, the buffer 5 is a self-resetting compression type hydraulic buffer.

[0040] Working principle: In the present invention, the hinge cup 2 and the hinge arm 1 are hingedly connected through the upper connecting rod 3 and the lower connecting rod 31. The upper connecting rod 3 and the lower connecting rod 31 are respectively fixed on the hinge cup 2 and the hinge arm 1, and the opening and closing movement of the hinge is realized by swinging the hinge cup and the hinge arm relative to each other.

[0041] A guide groove 21 penetrating the body is provided at the bottom of the hinge cup 2 and extending along the bottom of the hinge cup. A driving plate 4 is installed on the outer bottom of the hinge cup 2 and a slider 41 is provided on the top of the driving plate 4 and slidably installed in the guide groove 21.

[0042] A driving arm 32 extends from one end of the upper connecting rod 3 toward the hinge cup 2. When the hinge is closed, the driving arm 32 acts on the slider 41 to push the slider 41 to slide in the guide groove 21. This movement is guided by the guide groove 21 to ensure that the slider 41 moves smoothly along the predetermined path.

[0043] Among them, a buffer 5 is fixedly installed on the outer bottom of the hinge arm 1, and the piston rod or cylinder part of the buffer 5 is connected to the driving plate 4. When the slider 41 slides in the guide groove 21, the movement of the driving plate 4 is transmitted to the hydraulic system inside the buffer through the buffer 5. The buffer 5 is a self-resetting compression type hydraulic buffer, which produces a damping effect on the movement of the driving plate 4 through the internal hydraulic damping structure. This damping force can effectively alleviate the impact force during the hinge closing process, ensure that the hinge is closed slowly and smoothly, reduce noise and wear, and improve the user experience.

[0044] The driving plate 4 has guide plates 43 extending upwardly on both sides thereof, which cover and are fixed on the outer surfaces of both sides of the hinge cup 2. The inner side surface of the guide plate 43 is concavely formed with a clamping groove 44, in which the buffer 5 is clamped and fixed.

[0045] The side wall of the hinge cup 2 is extended outwardly to be provided with a positioning column 23, which is supported on the end face of the clamping groove 44 and limits the tail of the buffer 5 to ensure that the buffer 5 maintains a stable position during use to prevent displacement or falling off, thereby further improving the stability and reliability of the hinge structure.

[0046] One end of the guide groove 21 is provided with a mounting groove 22, and the mounting groove 22 is communicated with the guide groove 21. The slider 41 slides into the guide groove 21 through the mounting groove 22, ensuring that the slider 41 can smoothly enter the guide groove 21 for sliding motion.

[0047] Among them, the width of the installation groove 22 is greater than the width of the guide groove 21, and the width of the slider 41 is increased relative to the guide groove 21 and decreased relative to the installation groove 22, ensuring that the slider 41 can slide freely between the installation groove 22 and the guide groove 21 while maintaining its stability in the guide groove.

[0048] Compared with traditional technology: This solution has the following technical advantages: Breaking through the limitation of internal space: The buffer 5 is installed on the outside of the hinge arm 1, and the external space is effectively utilized through the design of the guide groove 21 and the driving plate 4, thereby avoiding the problem of limited internal space.

[0049] Simplified structure: The external buffer device makes the internal structure of the hinge cup 2 and the hinge arm 1 more concise, reduces the number and complexity of internal components, and improves the stability and reliability of the overall structure.

[0050] 3. Improve the damping effect: Since the buffer 5 is installed outside and is not limited by the internal space, a larger hydraulic buffer can be used to provide a stronger damping force, thereby improving the cushioning effect when the hinge is closed and effectively reducing impact and noise.

[0051] 4. Optimize the damping path: Through the design of the guide groove 21 and the slider 41, the movement path of the buffer 5 is ensured to be more optimized, the damping force is stably transmitted, and the overall buffering performance is improved.

[0052] 5. Loose manufacturing tolerance: The buffer device is installed on the outside and does not require high-precision assembly in a small internal space, which reduces the requirements for manufacturing tolerances, simplifies the manufacturing process, reduces the defective rate in the production process, and reduces production costs.

[0053] 6. Modular design: The buffer device is separated from the hinge cup 2 and the hinge arm 1, so that each component can be manufactured and assembled independently, further simplifying the production process and improving manufacturing efficiency. At the same time, through the cooperation of the guide groove 21 and the slider 41, it is ensured that the slider slides smoothly in the guide groove, improving the stability and accuracy of the hinge during opening and closing, avoiding the instability of the buffer effect caused by looseness or offset, so it can be widely promoted and used.

[0054] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
