Description

Technical Field

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

[0002] Buffering hardware hinges are equipped with damping devices to achieve smooth buffering during the opening and closing of the hinges, preventing noise and damage caused by excessive impact when the hinges are closed, improving the user experience and extending the service life of the product. Buffering hinges are widely used in various types of furniture, electronic products and daily utensils in daily life, and have become an indispensable and important part of modern hardware hinges.

[0003] However, the buffer hardware hinges in the prior art still have some deficiencies in design and application, which are specifically manifested in the following aspects: 1. Existing buffer hardware hinges usually set the damping device inside the hinge cup or hinge arm. However, since the internal space of the hinge cup and hinge arm is usually relatively small, such a design limits the installation space of the damping device. The small internal space requires the design of the damping device to be highly compact to adapt to the limited installation space. Although this design method can achieve a buffering effect to a certain extent, it increases the manufacturing complexity and cost of the damping device, and it is difficult to meet the modern demand for efficient buffering and long life.

[0004] 2. Due to the limited internal space of the hinge cup and hinge arm, the various components of the damping device need to be precisely manufactured to ensure that they can operate normally in a small space. This design not only increases the manufacturing difficulty, but also increases the defective rate during the production process, thus affecting the consistency and reliability of the product. The precise manufacturing process requirements will also lead to an increase in production costs, and the production of defective products may lead to a decrease in product durability.

[0005] 3. The narrow space between the hinge cup and the hinge arm directly limits the volume of the damper, resulting in the damper being unable to provide sufficient buffering force. Although a small-volume damper can achieve a certain degree of buffering, its buffering effect is difficult to reach an ideal level and cannot effectively reduce the impact force and noise generated when the hinge is closed. This may cause the hinge to have insufficient buffering in long-term use, affecting the user experience, especially in the case of high-frequency opening and closing.

[0006] 4. Due to the small size of the damper, the stress on its internal moving parts is large, which is easy to accelerate wear and tear, resulting in a gradual decrease in the damping effect. In addition, the small internal space may cause poor heat dissipation in the damper, which limits the performance of the damping device. As the temperature changes, the damper's oil may deteriorate, which in turn affects its long-term stable performance. These factors work together to significantly affect the service life of the damper. There is an urgent need to improve the design and structure of the damping device to extend its service life and improve its performance. Summary of the invention

[0007] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an outer slider hardware buffer hinge with a simple structure, easy use, and effective improvement in buffering effect and extension of service life without increasing manufacturing difficulty and cost.

[0008] The object of the present invention is achieved by the following method: an outer slider hardware buffer hinge, which includes a hinge cup and a hinge arm, the hinge cup and the hinge arm are hinged by an upper rocker arm and a lower rocker arm, the upper rocker arm and the lower rocker arm swing relative to the hinge cup and the hinge arm to realize the opening and closing of the hinge, the bottom of the hinge cup is provided with a first avoidance groove and a second avoidance groove, the first avoidance groove and the second avoidance groove are arranged through the bottom of the hinge cup body; The outer bottom of the hinge cup is also covered with a mounting slider, and the slider has a first side plate and a second side plate extending upward on both sides thereof, respectively covering the two outer side walls of the hinge cup; The top of the sliding block is provided with a first guide block and a second guide block, and the first guide block and the second guide block extend into the first avoidance groove and the second avoidance groove respectively to slide; The upper rocker arm is provided with a driving block extending downwards. When the hinge is closed, the driving block contacts the second guide block and pushes the slider to slide outside the hinge cup. A damper is arranged between the hinge cup and the slider, and the damper plays a damping role on the movement speed of the slider.

[0009] Furthermore: the first guide groove and the second guide groove that penetrate the slider are arranged on both sides of the first guide block, and the first hook and the second hook are extended inwardly of the groove on both sides of the first avoidance groove, and the first hook and the second hook extend into the first guide groove and the second guide groove respectively, and extend into the bottom of the first guide block.

[0010] Furthermore, the cross section of the second air avoidance groove is arranged in a "convex" shape, and a guide area is formed between the bottom of the second guide block and the sliding block, and the guide area is clamped on the side wall of the second air avoidance groove to slide.

[0011] Furthermore: the end face of the second avoidance groove is also provided with a limit hook extending toward the groove, and correspondingly, a positioning area is provided on the second guide block, and when the second guide block moves to the end of the second guide groove, the limit hook extends into the positioning area.

[0016] Furthermore: the driving block is arranged on the end surface of the upper rocker arm, and the driving block is arranged away from the hinge point between the upper rocker arm and the hinge cup.

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

[0018] 2. An important innovation of the present invention is that the buffer is installed on the outside of the hinge arm, which avoids the problem of difficulty in designing the buffer device due to limited internal space, which is common in traditional buffer hardware hinges.

[0019] 3. Since the buffer device of the present invention is arranged outside the hinge arm, the internal structure of the hinge cup and the hinge arm becomes simpler.

[0025] The present invention is further described in detail below with reference to the accompanying drawings. An outer slider hardware buffer 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 rocker arm 3 and a lower rocker arm 4, the upper rocker arm 3 and the lower rocker arm 4 swing relative to the hinge cup 1 and the hinge arm 2 to realize the opening and closing of the hinge, the bottom of the hinge cup 1 is provided with a first avoidance groove 11 and a second avoidance groove 12, the first avoidance groove 11 and the second avoidance groove 12 are arranged through the bottom of the hinge cup 1 body; The outer bottom of the hinge cup 1 is also covered with a mounting slide block 5, and the two sides of the slide block 5 are extended upward with a first side plate 51 and a second side plate 52, which respectively cover the two outer side walls of the hinge cup 1; The top of the sliding block 5 is provided with a first guide block 53 and a second guide block 54, and the first guide block 53 and the second guide block 54 extend into the first avoidance groove 11 and the second avoidance groove 12 respectively to slide; The upper rocker arm 3 is provided with a driving block 31 extending downward. When the hinge is closed, the driving block 31 contacts the second guide block 54 to push the slider 5 to slide outside the hinge cup 1. A damper 6 is provided between the hinge cup 1 and the slider 5 , and the damper 6 plays a damping role on the movement speed of the slider 5 .

[0026] In one of the embodiments: the first guide groove 55 and the second guide groove 56 penetrating the slider 5 are arranged on both sides of the first guide block 53, and the first hook 13 and the second hook 14 extend inwardly of the groove on both sides of the first avoidance groove 11, and the first hook 13 and the second hook 14 extend into the first guide groove 55 and the second guide groove 56 respectively, and extend into the bottom of the first guide block 53.

[0027] In one of the embodiments: the cross-section of the second air avoidance groove 12 is set in a "convex" shape, and a guide area 57 is formed between the bottom of the second guide block 54 and the sliding block 5, and the guide area 57 is clamped on the side wall of the second air avoidance groove 12 to slide.

[0028] In one of the embodiments: the end face of the second avoidance groove 12 is also provided with a limiting hook 15 extending in the groove direction, and correspondingly, a positioning area 58 is provided on the second guide block 54. When the second guide block 54 moves to the end of the second guide groove 56, the limiting hook 15 extends into the positioning area 58.

[0029] In one embodiment, the outer wall of the hinge cup 1 is recessed inward to form a mounting groove 16, the second side plate 52 covers the outside of the mounting groove 16, and the second side plate 52 and the mounting groove 16 together form a mounting area, and the damper 6 is fixed in the mounting area.

[0030] In one embodiment, the damper 6 is a compression damping type hydraulic damping cylinder, and the piston rod 61 of the damper 6 is connected to the second side plate 52 .

[0031] like Figure 1-8 As shown, in one of the embodiments: a connecting seat 62 is extended backward from the tail of the damper 6, a limiting opening 17 is provided on the hinge cup 1, and the other end of the connecting seat 62 extends into the limiting opening 17 for fixing, thereby playing a role in axial positioning of the damper 6.

[0032] like Fig. 9 As shown, in one of the embodiments: a positioning column 18 is extended from the side wall of the hinge cup 1 toward the damper 6 , and the tail of the damper 6 is supported on the positioning column 18 to perform axial positioning on the damper 6 .

[0033] In one of the embodiments: the driving block 31 is arranged on the end surface of the upper rocker arm 3 , and the driving block 31 is arranged away from the hinge point between the upper rocker arm 3 and the hinge cup 1 .

[0034] How it works The hinge cup 1 and the hinge arm 2 in the present invention are hinged by the upper rocker arm 3 and the lower rocker arm 4, so that the hinge can move relative to each other during the opening and closing process. When the hinge cup and the hinge arm swing through the rocker arm, the hinge completes the opening and closing action.

[0035] In this case, two air-avoiding grooves are provided at the bottom of the hinge cup, and a first guide block 53 and a second guide block 54 are provided at the top of the slider, which extend into the first air-avoiding groove 11 and the second air-avoiding groove 12 respectively and cooperate with the hooks in the grooves to ensure that the slider can move smoothly at the outer bottom of the hinge cup. At the same time, the connection structure also plays a role in connecting and positioning the slider and the hinge cup.

[0036] The upper rocker arm 3 is provided with a downwardly extending driving block 31. When the hinge is closed to a set angle, the driving block 31 contacts the second guide block 54 and pushes the slider 5 to slide outside the hinge cup. At this time, the slider cooperates with the damper to generate a damping force when the hinge is closed, so that the hinge can be closed slowly, reducing the impact force when the hinge is closed.

[0037] It is important to point out that a key technical innovation of the present invention is to install the damper 6 between the hinge cup 1 and the slider 5, and to achieve a buffering effect through the movement of the slider. The damper is located outside and is not limited by the internal space of the hinge cup and the hinge arm, so a larger and more powerful hydraulic buffer can be used. This hydraulic buffer can provide a greater damping force, thereby more effectively stabilizing the closing action of the hinge and reducing impact and noise. The piston rod 61 of the damper 6 is connected to the second side plate 52, providing a strong buffering effect.

[0038] Among them, in order to ensure the smooth closing of the hinge, the end face of the second air avoidance groove 12 is provided with a limit hook 15 extending toward the inside of the groove. The limit hook 15 cooperates with the positioning area 58 on the second guide block 54 to ensure that when the hinge is closed, the relative movement between the guide block and the slider is reasonably restricted, thereby making the movement of the slider more stable and smooth, thereby ensuring the stability of the opening and closing of the hinge.

[0039] Compared with the conventional technology, the present invention solves the problem of difficulty in designing the buffer due to the small internal space of the hinge cup and the hinge arm in the conventional design by placing the buffer device externally. The externally mounted buffer can utilize more space, avoiding the problem of limited space, thereby providing a more ideal buffering effect.

[0040] After the buffer is placed outside, the internal structure of the hinge cup and hinge arm becomes simpler. The number of complex internal parts is reduced, making the overall structure more stable and reliable. The precision requirements of internal parts are greatly reduced, thereby reducing manufacturing difficulty and production costs, while improving product consistency and stability.

[0041] In summary, by placing the buffer externally, the present invention not only solves the design and manufacturing difficulties caused by the small internal space in the prior art, but also further improves the performance and reliability of the hinge by improving the buffer effect and simplifying the internal structure. These innovations make the present invention have obvious technical advantages in improving user experience, extending service life and reducing production costs.

[0042] 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. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
