Description
Technical Field
[0001] The utility model relates to the technical field of damping hinges, and in particular to a damping hinge structure. Background Art
[0002] A damping hinge is a hinge that can provide damping force when opening or closing. It is widely used in cabinets, communications, rail transit, home appliances and other industries in life. Damping hinges can slow down the closing speed of objects such as cabin doors, inspection doors, and electrical screens, and reduce the impact force generated when closing.
[0003] The patent specification with announcement number CN219910425U discloses a damping hinge structure, which drives the plug-in rod to be plugged into the plug-in slot through the plug-in block, and then, the knob is turned. The rotation of the knob can drive the second bevel gear on the meshing first bevel gear to rotate through the rotating rod and the first bevel gear thereon. The rotation of the second bevel gear can drive the screw rod thereon to rotate synchronously, and then the rotation of the screw rod drives the extension rod threaded thereon to slide in the sliding seat and be plugged into the plug-in cavity for fixation. When disassembly is required, only the knob needs to be rotated in the opposite direction to drive the extension rod to slide back into the sliding seat, and then the hinge component can be easily installed and disassembled, and the connection is reinforced by multiple extension rods, which can bear the stress on the connection in multiple directions, thereby preventing the hinge component from loosening at the connection after long-term use, causing abnormal noise and affecting the user experience.
[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: the above device is not convenient for relatively stable fixed connection of the hinge during use, and it is easy to deviate during the connection process, resulting in poor hinge fixed connection effect. Therefore, further improvement is needed. Utility Model Content

DETAILED DESCRIPTION
[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Example 1
[0028] like Figure 1 to Figure 6 As shown, this embodiment proposes a damping hinge structure, including a hinge body 1, a first groove 12 and a second groove 13, the upper end of the hinge body 1 is provided with a slot 2, the upper end of the hinge body 1 is provided with a notch 3, the inner wall of the notch 3 is provided with a first circular groove 4, a placement block 5 is provided below the hinge body 1, the upper end of the placement block 5 is provided with a hinge placement groove 6, a connecting block 9 is movably provided inside the notch 3, a second circular groove 10 is provided on one side of the connecting block 9, and a third circular groove 11 is provided on the upper end of the connecting block 9.
[0029] In this embodiment, a first groove 12 is formed through the inner wall of the third circular groove 11 , and a second groove 13 is formed on the inner wall of the third circular groove 11 . The first groove 12 facilitates the round rod 14 to move along the third circular groove 11 , and the second groove 13 is used to fix the round rod 14 .
[0030] In this embodiment, a round rod 14 is movably provided inside the third circular groove 11 , and a handle bar 15 is fixedly provided at one end of the round rod 14 . The handle bar 15 facilitates the staff to pull the round rod 14 to move inside the third circular groove 11 .
[0031] In this embodiment, a protrusion 16 is fixedly provided on the outer surface of the round rod 14, and the protrusion 16 is movably connected to the first groove 12. The protrusion 16 is correspondingly engaged with the second groove 13. The engagement and fixation of the protrusion 16 and the second groove 13 can fix the round rod 14 and the third circular groove 11 to each other.
[0032] In this embodiment, two groups of circular clamping columns 17 are movably provided inside the second circular groove 10, and the circular clamping columns 17 correspond to the first circular groove 4. The two groups of circular clamping columns 17 can move into the interior of the first circular groove 4, so that the connecting block 9 and the hinge body 1 are clamped and fixed.
[0033] In this embodiment, a conical slide 18 is fixedly provided at one end of the circular clamping column 17, and a spring 19 is fixedly provided on the outer surface of the circular clamping column 17. The presence of the conical slide 18 makes it easier for the round rod 14 to push the two groups of circular clamping columns 17 to move along the second circular groove 10.
[0034] In this embodiment, the other end of the spring 19 is fixedly connected to the inner wall of the second circular groove 10 . The presence of the spring 19 prevents the circular clamping column 17 from being separated from the second circular groove 10 .
[0035] During use, when the hinge needs to be assembled, the staff first needs to take out the hinge body 1, and then the staff needs to fix one end of the connecting block 9 to the closed part of the outer cover, and then the staff aligns the first circular groove 4 with the second circular groove 10. At this time, the staff can push the handle rod 15 to make the round rod 14 move along the third circular groove 11 through the first groove 12. As the round rod 14 moves, the round rod 14 will touch the two groups of conical slides 18. As the round rod 14 continues to move, the round rod 14 pushes the two groups of circular clamping columns 17 to enter the first circular grooves 4 of the two groups respectively. At this time, under the action of the round rod 14, the hinge body 1 and the connecting block 9 can be connected. Next, the staff pushes the handle rod 15 again until the protrusion 16 is out of the range of the third circular groove 11, and then rotates the handle rod 15 to make the round rod 14 and the protrusion 16 rotate synchronously, so that the protrusion 16 corresponds to the position of the second groove 13, and then the staff pulls back the handle rod 15 to make the protrusion 16 enter the inside of the second groove 13. At this time, the protrusion 16 and the second groove 13 are engaged and fixed, and the assembly work of the hinge is completed. Due to the presence of the spring 19, when the round rod 14 is out of the range of the third circular groove 11, the circular clamping column 17 will return to the initial position, so that the hinge can be simply fixed, so as to facilitate the subsequent closing of the hinge.
[0036] Example 2
[0037] like Figure 2As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes
[0038] In this embodiment, soft blocks 7 are evenly fixed on the inner wall of the hinge placement groove 6, and two groups of threaded rods 8 are fixed on the inner wall of the hinge placement groove 6. The threaded rods 8 are movably arranged inside the slot 2, and the threaded rods 8 and the slot 2 are used to connect the hinge body 1 and the placement block 5. The soft blocks 7 are used to reduce the gap between the hinge body 1 and the placement block 5.
[0039] When the staff needs to close the outer cover, first the staff needs to pull the hinge body 1 downward until the hinge body 1 enters the hinge placement slot 6. At this time, the slot 2 will penetrate through the outer surface of the threaded rod 8. Then the staff puts a threaded cap on the upper end of the threaded rod 8 and rotates the threaded cap along the threaded rod 8 to tighten it. At this time, under the extrusion of the threaded cap, the hinge body 1 will continue to be extruded and moved downward. At this time, the hinge body 1 will pressurize the soft block 7, and under the action of the soft block 7, the gap between the hinge body 1 and the placement block 5 will be reduced, so that it is easy to reduce the gap when closing the outer cover, eliminating the labor steps of the staff.
[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
