Technical Field
[0001] This utility model relates to the field of hinge technology, and in particular to an improved hinge. Background Technology
[0002] A hinge is a mechanical device used to connect two relatively independent solids and allow them to rotate relative to each other. Hinges are very common furniture door connectors, utilizing the principle of movable hinges to allow the door to open or close around an axis. A hinge is mainly assembled from components such as a hinge cup, inner rocker arm, outer rocker arm, hinge body, triangular component, base, U-bolt, damping component, torsion spring, plastic tube, several connecting pins, and screws. Hydraulic hinges utilize the flow of high-density oil in hydraulic pipes to achieve a buffering effect, allowing the door to close gently even with force. During hinge assembly, the connections of each component need to be positioned to align the matching connecting holes and screw holes of the hinge body, hinge cup, base, inner strip assembly, inner rocker arm, and outer rocker arm. Then, the components are assembled into a single unit using rivets. Except for the damping component, the hinge body, combined with other components, forms the hinge body.
[0003] The applicant filed a patent application on September 19, 2024, with application number 202422286810X, entitled "A Novel Hinge," which discloses a novel hinge including an arm body, a base, a cup head, a four-hole component, and an inner strip assembly. The inner strip assembly is disposed on the arm body, and the first ends of the four-hole component and the inner strip assembly are hinged to the cup head via U-shaped pins. The last end of the four-hole component is hinged to the first end of the arm body via a first connecting pin. The inner strip assembly includes a laminate, a damping tube, and a damping seat, providing damping... A damping tube is installed inside the damping seat at the beginning of the arm body. The telescopic end of the damping tube extends out of the damping seat and abuts against the first connecting pin. The beginning of the stacked plate is hinged to the cup head, and the end of the stacked plate is hinged to the beginning of the arm body. A pull tab is provided on the tail end of the stacked plate. The damping seat has a slot on the side facing the stacked plate, allowing the pull tab to be inserted into the slot of the damping seat. When the hinge closes, the stacked plate pushes the damping seat towards the first connecting pin via the pull tab, thus slowing the closing speed of the hinge under the action of the damping tube. This invention simplifies the hinge structure, reduces assembly steps, and lowers production costs. However, the damping seat is made of plastic, which is easily damaged, thus affecting the service life of the hinge. Utility Model Content
[0004] The technical problem to be solved by this utility model embodiment is to provide an improved hinge.
[0005] To address the aforementioned technical problems, this utility model provides an improved hinge, comprising a hinge body and a damping assembly disposed within the hinge body. The hinge body includes an arm and an inner rocker arm rotatably disposed within the arm. The damping assembly includes a damping element, a linkage element, and a sleeve. The hydraulic pipe of the damping element is sleeved within the sleeve, which is fixedly disposed within the arm. The linkage element is slidably mounted on the sleeve, and the spindle of the damping element abuts against the inner wall of the linkage element. The linkage element is slidably disposed within the arm and linked with the inner rocker arm. When the hinge is closed, the inner rocker arm rotates and pushes the linkage element to compress the damping element, causing the hinge to close slowly under the resistance of the hydraulic pipe.
[0006] Furthermore, the inner rocker arm has an extension, and the linkage has a through hole. The extension is inserted into the through hole. When the inner rocker arm rotates, the linkage slides to compress the damping element.
[0007] Furthermore, the sleeve abuts against the torsion spring inside the arm body, and the extension portion cooperates with the sleeve through the linkage to limit the damping element.
[0008] Furthermore, the sleeve has a slot, the shape of which is adapted to the shape of the hydraulic pipe, and the hydraulic pipe is disposed within the slot.
[0009] Furthermore, it also includes a decorative element, which is disposed on the damping assembly. The decorative element has a notch, the inner width of which is adapted to the outer width of the tail of the inner rocker arm. First snap-fit grooves are provided on both sides of the notch, and the first snap-fit grooves are snapped onto the first connecting pin of the arm body.
[0010] Furthermore, the outer width of the sleeve is adapted to the inner width of the linkage component.
[0011] Furthermore, the linkage is made of metal, while the sleeve and the decorative part are made of plastic.
[0012] Furthermore, the hinge body also includes a hinge cup and an outer rocker arm. Both ends of the outer rocker arm and the inner rocker arm are rotatably connected to the hinge cup and the arm body, respectively. The torsion spring is sleeved at the connection between the outer rocker arm and the arm body.
[0013] Furthermore, the outer rocker arm and the inner rocker arm are rotatably connected to the hinge cup via a U-shaped pin.
[0014] Furthermore, one end of the torsion spring abuts against the end of the arm body, and the other end abuts against the first connecting pin.
[0015] Implementing the embodiments of this utility model has the following beneficial effects:
[0016] The linkage is made of metal, which makes it more durable when in contact with the spindle, which is also made of metal. The sleeve covers the hydraulic pipe and abuts against the torsion spring, which can protect the hydraulic pipe and extend the overall service life of the hinge.
[0017] The damping components do not require mechanical connection with the arm body and inner rocker arm. Quick connection can be achieved by utilizing the extension and sleeve on the inner rocker arm, thereby reducing the number of hinge parts, thus reducing the assembly process and cost of the hinge.
[0018] The damping assembly is decorated with decorative parts to conceal the connection between the inner rocker arm and the damping assembly, making the hinge more aesthetically pleasing and preventing the linkage from dislodging, thereby improving the stability of the linkage.
[0019] The base and trim are made of plastic, which greatly reduces the cost of the hinge. Attached Figure Description

[0028] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.
[0029] like Figure 1-6 As shown, an improved hinge includes a hinge body and a damping assembly 1 detachably disposed within the hinge body. The hinge body comprises an arm 2 and an inner rocker arm 3 and a torsion spring 4 rotatably disposed within the arm 2. The damping assembly 1 includes a damping element 11, a linkage element 12, and a sleeve 13. One end of the sleeve 13 is fitted onto the hydraulic pipe 111 of the damping element 11, covering the hydraulic pipe 111 and abutting against the torsion spring 4, thus protecting the hydraulic pipe 111 and extending the overall service life of the hinge. The other end abuts against the torsion spring 4. One end abuts against the end of the arm body 2, and the other end abuts against the first connecting nail 21; the spindle 112 of the damping element 11 abuts against the inner wall of the linkage 12, the spindle 112 is inserted into the hydraulic pipe 111, and the hydraulic pipe 111 is set in the slot 131; the damping element 11 and the sleeve 13 are synchronously slidably set in the linkage 12, the linkage 12 is slidably set in the arm body 2 and connected to the inner rocker arm 3; when the hinge is closed, the inner rocker arm 3 rotates and pushes the linkage 12 to compress the damping element 11, and the hinge is slowly closed under the resistance of the hydraulic pipe 111.
[0030] like Figure 1-3 As shown, the inner rocker arm 3 has an extension 31, and the linkage 12 has a through hole 121. The extension 31 is inserted into the through hole 121. When the inner rocker arm 3 rotates, the linkage 12 slides, causing the damping member 11 to compress or release. The outer width of the sleeve 13 matches the inner width of the linkage 12, and the sleeve 13 has a slot 131. The shape of the slot 131 matches the shape of the hydraulic pipe 111. Preferably, the linkage 12 is made of metal, which makes it more durable in contact with the spindle 112, which is also made of metal. The sleeve 13 and the decorative part 5 are made of plastic.
[0031] like Figure 1 , 2 As shown in Figure 6, the decorative part 5 is covered on the damping assembly 1. The decorative part 5 has a notch 53. The inner width of the notch 53 is adapted to the outer width of the tail of the inner rocker arm 3. The inner rocker arm 3 rotates within the notch 53. The notch 53 has a first locking groove 51 on both sides. The first locking groove 51 is locked onto the first connecting pin 21 of the arm body 2. The inner rocker arm 3 is rotatably connected to the arm body 2 through the first connecting pin 21. The decorative part 5 has a second locking groove 52. The second locking groove 52 is locked onto the second connecting pin 22 on the arm body 2. The connection between the decorative part 5 and the arm body 2 is more stable.
[0032] like Figure 1 As shown, the hinge body also includes a hinge cup 6 and an outer rocker arm 7. Both ends of the outer rocker arm 7 and the inner rocker arm 3 are rotatably connected to the hinge cup 6 and the arm body 2, respectively. A torsion spring 4 is sleeved at the connection between the outer rocker arm 7 and the arm body 2. The outer rocker arm 7 and the inner rocker arm 3 are rotatably connected to the hinge cup 6 via U-shaped nails 8. The hinge cup 6 is used for fixed connection to the door body. The base 9 is detachably mounted on the rear of the arm body 2 via screws and is used for fixed connection to the cabinet body.
[0033] The working principle of this embodiment is as follows:
[0034] When the hinge is closed, the hinge cup 6 drives the inner rocker arm 3 and the outer rocker arm 7 to rotate around the U-shaped nail 8 towards the arm body 2. At the same time, the inner rocker arm 3 rotates around the first connecting nail 21. The extension 31 of the inner rocker arm 3 pushes the linkage 12 to move towards the hinge cup 6, causing the damping element 11 to be compressed. In this way, the resistance of the hydraulic pipe 111 is used to counteract the elastic force generated by the torsion spring 4, thereby slowing down the closing speed of the hinge, making it close slowly and smoothly, reducing the impact force between the door and the cabinet, and extending the service life of the hinge.
[0035] When the hinge is opened, the hinge cup 6 drives the inner rocker arm 3 and the outer rocker arm 7 to rotate around the U-shaped nail 8 in a direction away from the arm body 2. At the same time, the inner rocker arm 3 rotates around the first connecting nail 21. The extension 31 of the inner rocker arm 3 pushes the linkage 12 to move away from the hinge cup 6, so that the damping element 11 is released until the hinge cup 6 is fully opened.
[0036] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model, and their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit and essence of the main technical solution of this utility model should be covered within the protection scope of this utility model.
