Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a hinge with a buffer function. Background Technology

[0002] A hinge is a mechanical device used to connect two solids and allow them to rotate relative to each other. It typically consists of two or more cooperating parts that are connected by a shaft, pin, or other means to enable the connected objects to rotate about a specific axis.

[0003] A Chinese patent discloses a hinge (authorization announcement number CN221973269U). This patented technology adopts a unique design of a first fixed seat, an up-and-down adjustable base, a second fixed seat, and a base, which not only improves the stability of the product but also facilitates its adjustment.

[0004] Regarding the above and existing related technologies, the inventor believes that the following defects often exist: existing hinges generally only have ordinary rotation function when in use and do not have a buffering effect. This causes a large impact or collision between the two connecting parts or between the cabinet door and the cabinet body when the cabinet door is closed with a large force. Such frequent collisions will cause serious wear on the connecting parts of the hinge, such as the pin and the bushing, thus affecting the service life of the hinge. Utility Model Content

[0005] The technical problem to be solved by this invention is that the existing technology has the disadvantage that the hinge cannot buffer the impact force. Therefore, we propose a hinge with buffering function.

[0006] To achieve the above objectives, this application adopts the following technical solution: a hinge with a buffer function, including a first fixed seat, a second fixed seat mounted on one side of the first fixed seat, a connecting arm mounted on the top of the second fixed seat, the connecting arm mounted on one side of the first fixed seat, a fixed cavity fixedly connected to the other side of the first fixed seat, a damping mechanism installed inside the fixed cavity, a sliding plate slidably connected inside the damping mechanism, a contact plate fixedly connected to one side of the sliding plate, an energy storage spring fixedly connected to the side of the contact plate near the damping mechanism, a fixed ring fixedly connected to the surface of the damping mechanism, and the side of the energy storage spring near the fixed ring fixedly connected to the fixed ring.

[0007] Preferably, the damping mechanism has grooves at both the front and rear ends, and sliders are fixedly connected to both the front and rear ends of the sliding plate, with the grooves slidably connected to the sliders.

[0008] Preferably, the surface of the contact plate is provided with contact particles, the number of contact particles being several and evenly distributed on the surface of the contact plate, and the material of the contact particles being rubber.

[0009] Preferably, the spring constant of the energy storage spring is 10N.

[0010] Preferably, the main body and internal materials of the first fixing seat, the second fixing seat, and the connecting arm are all made of aluminum alloy.

[0011] Preferably, the internal components of the connecting arm are coated with a self-lubricating coating.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by employing a device body that combines a damping mechanism with an energy storage spring, the energy storage spring can effectively reduce the impact force and noise generated by the collision between the cabinet body and the cabinet door when the cabinet door is closed, and also reduce the mutual friction between the internal components of the device, thereby reducing the wear of the connecting parts and greatly extending the service life of the hinge.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figure 1 - Figure 4As shown, this utility model provides a technical solution: a hinge with a buffer function, including a first fixed seat 1, a second fixed seat 2 installed on one side of the first fixed seat 1, a connecting arm 3 installed on the top of the second fixed seat 2, the connecting arm 3 installed on one side of the first fixed seat 1, a fixed cavity 4 fixedly connected to the other side of the first fixed seat 1, a damping mechanism 5 installed inside the fixed cavity 4, a sliding plate 6 slidably connected inside the damping mechanism 5, a contact plate 7 fixedly connected to one side of the sliding plate 6, an energy storage spring 8 fixedly connected to the side of the contact plate 7 near the damping mechanism 5, a fixed ring 9 fixedly connected to the surface of the damping mechanism 5, and the side of the energy storage spring 8 near the fixed ring 9 fixedly connected to the fixed ring 9. By using the device body in which the damping mechanism 5 and the energy storage spring 8 work together, when the cabinet door is closed, the impact force and noise generated by the collision between the cabinet body and the cabinet door can be effectively reduced by the buffering effect of the energy storage spring 8, and the mutual friction between the internal components of the device can be reduced, thereby reducing the wear of the connection parts and greatly extending the service life of the hinge.

[0021] Reference Figure 4 As shown in this embodiment: the front and rear ends of the damping mechanism 5 are provided with sliding grooves 10, and the front and rear ends of the sliding plate 6 are fixedly connected with sliders 11. The interior of the sliding groove 10 is slidably connected to the sliders 11. Through the setting of the sliding groove 10 and the sliders 11, the sliding plate 6 can provide a stable limiting and guiding effect when moving inside the damping mechanism 5, thereby making the movement trajectory of the energy storage spring 8 more stable and effectively improving the stability during use.

[0022] Reference Figure 3 As shown in this embodiment: contact particles 12 are installed on the surface of the contact plate 7. The number of contact particles 12 is several and they are evenly distributed on the surface of the contact plate 7. The material of the contact particles 12 is rubber. By using contact particles 12 made of rubber, when the connecting arm 3 contacts the contact plate 7, the contact area between the contact plate 7 and the connecting arm 3 can be significantly increased, thereby making the device more stable when generating a buffering effect and effectively improving the use effect.

[0023] Reference Figure 4 As shown in this embodiment, the elastic coefficient of the energy storage spring 8 is 10N. By using the energy storage spring 8 made with a specific elastic coefficient, the connecting arm 3 can have a gentler buffering effect when it comes into contact with the contact plate 7, which effectively reduces the reaction force and improves the user experience.

[0024] Reference Figure 1As shown in this embodiment, the main body and internal materials of the first fixing seat 1, the second fixing seat 2 and the connecting arm 3 are all made of aluminum alloy. By using the first fixing seat 1, the second fixing seat 2 and the connecting arm 3 made of aluminum alloy, the device can have better anti-friction and anti-pressure capabilities during use, thereby effectively extending the service life of the device and preventing it from being easily damaged.

[0025] Reference Figure 2 As shown in this embodiment, the internal components of the connecting arm 3 are all covered with a self-lubricating coating. By setting the self-lubricating coating on the internal components of the connecting arm 3, the internal components of the connecting arm 3 can have less friction and are less prone to damage when they move relative to each other, thereby effectively improving the smoothness and stability of the device when opening and closing.

[0026] Working Principle: The main body of the device, employing a damping mechanism 5 in conjunction with an energy storage spring 8, effectively reduces the impact force and noise generated by the collision between the cabinet body and the door when the cabinet door is closed, thanks to the buffering effect of the energy storage spring 8. This also reduces friction between internal components, thus lessening wear on connecting parts and significantly extending the hinge's lifespan. The sliding groove 10 and slider 11 provide stable limiting and guiding for the sliding plate 6 as it moves within the damping mechanism 5, further stabilizing the movement trajectory of the energy storage spring 8 and effectively improving stability during use. The use of rubber contact particles 12 significantly increases the contact area between the contact plate 7 and the connecting arm 3 when the connecting arm 3 contacts the contact plate 7. To make the device more stable when generating a buffering effect and effectively improve the usage effect, the energy storage spring 8 made with a specific elastic coefficient can make the connecting arm 3 have a gentler buffering effect when it comes into contact with the contact plate 7, effectively reducing the reaction force and improving the user experience. The first fixing seat 1, the second fixing seat 2 and the connecting arm 3 made of aluminum alloy can make the device have good anti-friction and anti-compression capabilities during use, thereby effectively extending the service life of the device and preventing easy damage. By setting a self-lubricating coating on the internal components of the connecting arm 3, the internal components of the connecting arm 3 can have less friction when they move with each other and are not easy to be damaged, thereby effectively improving the smoothness and stability of the device when opening and closing.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
