Abstract
Description
Technical Field
[0001] This invention relates to the field of heavy-duty hinge technology, specifically a concealed, three-dimensionally adjustable, damped heavy-duty top and bottom hinge device. Background Technology
[0002] In the installation and use of heavy-duty doors, hinges, as the core component connecting the door body and the door frame, directly affect the door's opening and closing stability, safety, and service life. As industrial sectors increasingly demand higher load-bearing capacity, installation precision, and user experience for heavy-duty doors, traditional hinges are no longer sufficient to meet the stringent requirements of heavy-duty scenarios. Hinges with high-precision adjustment, shock absorption, and concealed design have become an important direction for industry development.
[0003] Currently, heavy-duty hinges on the market generally suffer from the following shortcomings: First, limited adjustment functions. Most hinges can only achieve single-direction or coarse positional adjustments, making precise calibration in three-dimensional space difficult. This leads to problems such as tilting and uneven gaps after door installation, affecting sealing performance and aesthetics. Second, insufficient buffering performance. Heavy-duty doors have a large self-weight and strong impact force during opening and closing. Traditional hinges lack effective damping and buffering structures, easily causing rigid collisions between the door and the door frame, generating noise and shortening the lifespan of both the hinges and the door. Third, unreasonable structural design. Some hinge adjustment components and moving parts are exposed, affecting the overall aesthetics of the door and making them susceptible to corrosion from environmental factors such as dust and oil, leading to adjustment failure or movement jamming. Fourth, poor adaptability. Traditional hinges cannot meet diverse installation needs for heavy-duty doors of different weights and sizes through flexible adjustments, increasing construction difficulty and costs. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a concealed, three-dimensionally adjustable, damped heavy-duty top and bottom hinge device, which solves the problems of limited adjustment function, insufficient buffering performance, unreasonable structural design, and poor adaptability.

[0007] Preferably, the second adjustment mechanism includes an inner rocker arm located at the rear end of the outer rocker arm. The bottom end of the inner rocker arm is rotatably connected to the adjacent side of the first and second movable plates via a pin. The rear end of the top of the inner rocker arm is connected to the movable cup holder via a fixing component.
[0008] Preferably, the third adjustment component includes a third inclined block located on the left side of the movable cup holder, a second inclined block slidably connected to the middle end of the third inclined block, and the middle end of the second inclined block connected to the movable cup holder via a third adjustment screw.
[0009] Preferably, the fixing component includes a gasket located on the rear side of the top end of the inner rocker arm, and fixing plates are provided at both ends of the gasket. The fixing plates are bolted to the inner wall of the front end of the movable cup holder.
[0010] Preferably, the adjacent sides of the fixing plates at the left and right ends are rotatably connected to the top of the outer rocker arm and the top of the inner rocker arm via two pins.
[0011] Preferably, the front ends of the movable plate one and the movable plate two on the adjacent side are connected to a damping block by a pin, and the front end of the damper abuts against the rear end of the damping block.
[0012] Preferably, the top of the through groove is provided with a slot, and two limiting shims are installed in the slot, with the adjacent side of the two limiting shims contacting the outer wall of the first adjusting screw.
[0013] Preferably, the bottom end of the outer rocker arm is provided with a spring guide pin, and the top end of the spring guide pin abuts against the arc surface, and a spring is sleeved on the outer wall of the spring guide pin.
[0014] Preferably, both the first and second movable plates have fan-shaped grooves at their rear ends, which are used to accommodate the displacement of the spring and the spring guide pin.
[0015] Working principle: During assembly, first, take out the adjusting seat, then put the first wedge into the groove at the front of the adjusting seat, then screw the first adjusting screw into the groove from the top of the adjusting seat and into the screw hole at the top of the first wedge, thus installing the first wedge into the groove at the front of the adjusting seat. Then insert the limiting washer into the slot at the top of the groove, and then tighten the first adjusting screw. Then screw the second adjusting screw into the top of the adjusting seat, and then insert the damper into the bottom of the adjusting seat to obtain component one. Next, place component one in the predetermined position on moving plate one, take out the outer rocker arm and inner rocker arm, and place them in the predetermined position on moving plate one. Then, place the damping block at the front end of moving plate one, and make the damping block and the front end of the damper contact each other. Then, connect moving plate two to moving plate one through a pin, so that the outer rocker arm and inner rocker arm can rotate, and component two can be obtained. Then, the spring is fitted onto the outer wall of the spring guide pin and placed into the fan-shaped groove on the first and second movable plates, so that the top of the spring guide pin contacts the arc surface of the rear end of the outer rocker arm, thus obtaining component three. Next, insert the second inclined block into the middle of the third inclined block and place it into the movable cup holder. Use the third adjusting screw to connect them together with the movable cup holder. Then, connect the two fixing plates to the top of the outer rocker arm and the inner rocker arm with pins. The two fixing plates are located on the left and right sides of the outer rocker arm, respectively. Then, place the shim between the two fixing plates, that is, the rear end of the inner rocker arm. Then, place them into the bottom inner wall of the movable cup holder and fix the two fixing plates and the shim to the bottom inner wall of the movable cup holder with bolts to obtain part four. Finally, place component four between outer shell one and outer shell two, and connect outer shell one and outer shell two together with rivets to complete the assembly; When the outer rocker arm and the inner rocker arm rotate, the outer rocker arm rotates with its middle section as the rotation point, and the inner rocker arm rotates with its bottom section as the rotation point. When the outer rocker arm rotates, the front side of its bottom section can contact the rear end of the damper, thus enabling the damper to function. Furthermore, the arc surface of the rear end of the outer rocker arm can contact the top of the spring guide pin, thereby compressing the spring through the spring guide pin. When the first adjusting screw is turned, the first inclined block can move. Since the slider and the slide groove can cooperate with each other, and the first moving plate is fixed to the first outer shell, and the second moving plate is fixed to the second outer shell, when the first inclined block moves, the first inclined block can move the adjusting seat, thereby adjusting the position of the damper. When the third adjusting screw is turned, the second inclined block can move, thereby moving the third inclined block, thus adjusting the position of the outer rocker arm and the inner rocker arm within the movable cup holder.
[0016] This invention provides a concealed, three-dimensionally adjustable, damped, heavy-duty top and bottom hinge device. It has the following advantages: 1. This invention achieves three-dimensional precise adjustment through multiple sets of adjustment components. The first adjustment component, in conjunction with the adjustment screw, can flexibly adjust the position of the damper. The third adjustment component, through the linkage of the second and third adjustment blocks and the screw, can precisely adjust the position of the rocker arm within the movable cup holder, solving the problem of inconvenient adjustment of traditional hinges, meeting the stringent requirements for installation accuracy in heavy-duty scenarios, and improving the adaptability of the device.
[0017] 2. The device of this invention integrates a damper and a spring structure. When the outer rocker arm rotates, the damper and the damping block work together to provide buffering, and the spring is assisted in resetting by the guide pin. The dual mechanism ensures that the heavy door opens and closes smoothly and avoids violent impact. At the same time, the hidden design reduces exposed parts, taking into account both functionality and aesthetics, and extending service life. Attached Figure Description

[0021] Example: Please see the appendix Figure 1 -Appendix Figure 6This invention provides a concealed, three-dimensionally adjustable, damped heavy-duty top and bottom hinge device, comprising a second outer shell 2 connected to the right side of an outer shell 1 by rivets, a movable plate 6 on the right side of the outer shell 1, and a movable plate 14 on the left side of the outer shell 2. The movable plates 6 and 14 are connected by multiple bolts. Both movable plates 6 and 14 have grooves at their front ends. These bolts are used partly to connect the movable plates 6 and 14 together and partly for the rotation of the outer rocker arm 3 and the inner rocker arm 4. An adjusting seat 7 is provided on a side adjacent to the movable plates 6 and 14. A through groove is formed at the middle of the adjusting seat 7, and an inclined block 8 is provided within the through groove. The top end has a screw hole of a size that matches the first adjusting screw 11, and both ends of the inclined block 8 are fixedly connected to sliders. The sliders can be inserted into the sliding grooves at the front ends of the movable plate 6 and the movable plate 14. When the first adjusting screw 11 is rotated, the inclined block 8 can move. Since the slider and the sliding groove can cooperate with each other, and the movable plate 6 is fixed to the outer shell 1, and the movable plate 14 is fixed to the outer shell 2, when the inclined block 8 moves, the inclined block 8 can move the adjusting seat 7, thereby adjusting the position of the damper 21. The top end of the inclined block 8 is connected to the adjusting seat 7 through the first adjusting screw 11. The second adjusting screw 12 is installed in the middle of the top end of the adjusting seat 7. A damper 21 is provided at the bottom end of the adjusting seat 7, and an outer rocker arm 3 is provided at the rear end of the adjusting seat 7. When the outer rocker arm 3 rotates, the front side of the bottom end of the outer rocker arm 3 can contact the rear end of the damper 21, and the arc surface of the rear end of the outer rocker arm 3 can contact the top end of the spring guide pin 20, thereby compressing the spring 9. The middle end of the outer rocker arm 3 is rotatably connected to the adjacent side of the moving plate 1 6 and the moving plate 2 14 through a pin. An inner rocker arm 4 is provided at the rear end of the outer rocker arm 3. When the inner rocker arm 4 rotates, the bottom end of the inner rocker arm 4 is rotatably connected to the adjacent side of the moving plate 1 6 and the moving plate 2 14 through a pin. A pad 18 is provided at the rear end of the top end of the inner rocker arm 4. The pad 18 is used to connect the outer rocker arm 3, the inner rocker arm 4 and the movable cup seat 5. The two ends of the gasket 18 are both equipped with fixing plates 19. The fixing plates 19 are bolted to the inner wall of the front end of the movable cup seat 5.

The middle end of the two-slope block 15 is connected to the movable cup seat 5 through a third adjusting screw 13. When the third adjusting screw 13 is rotated, the two-slope block 15 can be moved, which in turn moves the three-slope block 16, thereby adjusting the position of the outer rocker arm 3 and the inner rocker arm 4 in the movable cup seat 5.
[0022] Please see the appendix Figure 7 -Appendix Figure 11The two end plates 19 are rotatably connected to the top of the outer rocker arm 3 and the top of the inner rocker arm 4 via two pins. The front ends of the movable plate 11 and movable plate 214 are connected to damping blocks 10 via pins, and the front end of the damper 21 abuts against the rear end of the damping block 10. By setting the damping block 10 to abut against the front end of the damper 21, the damper 21 can function. A slot is provided at the top of the through groove, and two limiting washers 17 are installed in the slot. The adjacent sides of the two limiting washers 17 contact the outer wall of the first adjusting screw 11. A spring guide pin 20 is provided at the bottom end of the outer rocker arm 3, and the top end of the spring guide pin 20 abuts against the arc surface. A spring 9 is sleeved on the outer wall of the spring guide pin 20. When the arc surface of the rear end of the outer rocker arm 3 moves against the top end of the spring guide pin 20, the spring guide pin 20 can compress the spring 9. Conversely, when the spring 9 returns to its original position, it can push the spring guide pin 20 to move, thereby pushing the outer rocker arm 3 to rotate. The rear ends of the first movable plate 6 and the second movable plate 14 are both provided with fan-shaped grooves. The fan-shaped grooves are used to accommodate the displacement of the spring 9 and the spring guide pin 20. When the spring guide pin 20 and the spring 9 are in action, the fan-shaped grooves can accommodate the displacement of the spring guide pin 20 and the spring 9.
