Description
Technical Field
[0001] This utility model relates to the field of hinge technology, and in particular to a novel hinge with a built-in damper in the hinge cup. Background Technology
[0002] A hinge, also known as a hinge plate, is a mechanical device used to connect two solids and allow them to rotate relative to each other. The hinge cup is the fixing device that forms the two solids of the hinge. During the opening and closing process, the hinge may fall off due to excessive rotational force. Therefore, a new type of hinge with a built-in damper in the hinge cup is needed.
[0003] The existing hinge buffer assembly cannot be disassembled as a whole, which is not conducive to the replacement by the staff. The device is also inconvenient for the staff to disassemble and separate, and it is not convenient to replace the positioning piece individually. The device of this utility model makes it convenient for the staff to disassemble the buffer assembly as a whole and to disassemble and replace the positioning piece. Utility Model Content
[0004] The purpose of this utility model is to provide a new type of hinge with a built-in damper, which solves the problems of not being able to be disassembled as a whole, making it inconvenient for workers to replace, and the inconvenience of disassembling and separating the device, as well as the difficulty in replacing the positioning piece individually.
[0005] To achieve the above objectives, a novel hinge with a built-in damper is provided, comprising: a first positioning piece and a second positioning piece; a limiting block is attached to the lower surface of the second positioning piece; a slide rod is fixedly connected to the upper surface of the limiting block; a mounting post is fixedly connected to the upper end of the slide rod; a limiting cap is threaded onto the outside of the mounting post; the lower surface of the limiting cap is attached to the upper surface of the second positioning piece; two annular frames are fixedly connected to the outside of the slide rod; and a buffer assembly is provided on the outside of the slide rod, which can be completely disassembled for easy replacement.
[0006] The second positioning piece has a connecting block slidably connected inside, with one end of the connecting block extending to the outside of the second positioning piece. Two rotating plates are fixedly connected to the side of the first positioning piece, and one end of the connecting block is positioned between the two rotating plates. A rotating column is rotatably connected inside the connecting block, with the lower end of the rotating column inserted into the upper surface of the lower rotating plate and the upper end of the rotating column penetrating through the upper rotating plate. A second spring is fixedly connected to the inner wall of the rotating column, and a plug rod is fixedly connected to one end of the second spring. The end of the plug rod away from the second spring is slidably connected to the inner wall of the rotating plate. A third spring is fixedly connected to the inner wall of the plug rod, and a limiting rod is slidably connected to the inner wall of the plug rod. The lower end of the limiting rod is slidably connected to the inside of the rotating column, and an installation ring is fixedly connected to the outside of the limiting rod. The upper surface of the installation ring is fixedly connected to the lower end of the third spring. This design facilitates the separation of the first and second positioning pieces by the operator, allowing for individual replacement.
[0007] According to the novel hinge with built-in damper, the damping assembly includes a push plate, a first spring, a slider, and a push rod. One end of the first spring is fixedly connected to the side of the annular frame. The inside of the slider is slidably connected to the outside of the slide rod. The side of the slider is fixedly connected to one end of the first spring. One end of the push rod is rotatably connected to the side of the slider. The side of the push plate is rotatably connected to the end of the push rod away from the slider. The other side of the push plate is in contact with the side of the connecting block. This design facilitates damping when subjected to a large opening force.
[0008] According to the novel hinge with built-in buffer, the upper end of the limiting rod extends to the outside of the rotating column, and the side surface of the limiting rod is slidably connected to the inner wall of the rotating column, making it convenient for workers to grasp the limiting rod.
[0009] According to the novel hinge with built-in damper, the first spring is sleeved outside the slide rod, and the third spring is sleeved outside the limiting rod, which can limit the first spring and the third spring, facilitating the linear contraction and rebound of the first spring and the third spring.
[0010] According to the novel hinge with built-in damper, the first and second positioning plates are provided with mounting holes at the four corners of their side surfaces. The inner walls of the mounting holes are fixedly connected with internal threads, which facilitates installation by the operator using screws.
[0011] According to the novel hinge with built-in buffer, the limiting block has a square cross-section and the limiting cap has a circular cross-section, which prevents the limiting block from rotating with the limiting cap when the limiting cap is rotated, making it convenient for workers to disassemble.
[0012] According to the novel hinge with built-in damper, the slide bar has a square cross-section, and the side surface of the mounting ring is slidably connected to the inner wall of the insert bar, which can prevent the push plate from rotating and facilitate the installation of the damping component by the staff.
[0013] The above-mentioned solution has the following beneficial effects:
[0014] 1. When it is necessary to disassemble the buffer assembly, the limit cap can be rotated to remove it from the mounting post, which makes it easy to release the limit cap from the slide rod and the limit plate, and the buffer assembly can be disassembled as a whole for easy replacement.
[0015] 2. When it is necessary to separate the first and second positioning pieces, pull the limiting rod to release its restriction on the insertion rod, facilitating the sliding of the insertion rod. The limiting rod then drives the insertion rod to slide, releasing its restriction on the rotating column, making it easy to pull out the rotating column. The rotating column then releases its restriction on the rotating plate. When installation is required, the second spring pushes the insertion rod into the rotating plate, thus limiting the rotating column. The third spring pushes the mounting ring and the limiting rod downwards, facilitating the limiting rod's restriction on the insertion rod, preventing it from moving freely, making the installation more stable, and allowing workers to easily separate the first and second positioning pieces for individual replacement.

[0026] Reference Figure 1-5 This utility model discloses a novel hinge with a built-in damper, comprising: a first positioning piece 1 and a second positioning piece 2. The lower surface of the second positioning piece 2 is fitted with a limiting block 17, which prevents the slide rod 7 from rotating with the limiting cap 3. The upper surface of the limiting block 17 is fixedly connected to the slide rod 7, which is used to install a damping assembly 9. The upper end of the slide rod 7 is fixedly connected to a mounting post 6, which is used to install the limiting cap 3. The mounting post 6 is externally threaded to the limiting cap 3, which is used to limit the slide rod 7. The lower surface of the limiting cap 3 is fitted with the upper surface of the second positioning piece 2. Two annular frames 16 are fixedly connected to the outside of the slide rod 7 for installing a first spring 903. A damping assembly 9 is provided on the outside of the slide rod 7 for damping.
[0027] A connecting block 5 is slidably connected inside the second positioning piece 2. One end of the connecting block 5 extends to the outside of the second positioning piece 2. Two rotating plates 4 are fixedly connected to the side of the first positioning piece 1. One end of the connecting block 5 is positioned between the two rotating plates 4. A rotating column 12 is rotatably connected inside the connecting block 5 for rotating the first positioning piece 1. The lower end of the rotating column 12 is inserted into the upper surface of the lower rotating plate 4, and the upper end of the rotating column 12 passes through the upper rotating plate 4. A second spring 11 is fixedly connected to the inner wall of the rotating column 12 for pushing the insertion rod 15 to move. One end of spring 11 is fixedly connected to a rod 15, which is used to limit the rotation column 12. The end of the rod 15 away from the second spring 11 is slidably connected to the inner wall of the rotating plate 4. The inner wall of the rod 15 is fixedly connected to a third spring 14, which pushes the limiting rod 10 to move. The inner wall of the rod 15 is slidably connected to the limiting rod 10. The lower end of the limiting rod 10 is slidably connected to the inside of the rotation column 12. The outer side of the limiting rod 10 is fixedly connected to a mounting ring 13, and the upper surface of the mounting ring 13 is fixedly connected to the lower end of the third spring 14.
[0028] The buffer assembly 9 includes a push plate 901, a first spring 903, a slider 904, and a push rod 905. One end of the first spring 903 is fixedly connected to the side of the annular frame 16. The inside of the slider 904 is slidably connected to the outside of the slide rod 7. The side of the slider 904 is fixedly connected to one end of the first spring 903. One end of the push rod 905 is rotatably connected to the side of the slider 904. The side of the push plate 901 is rotatably connected to the end of the push rod 905 away from the slider 904. The other side of the push plate 901 is in contact with the side of the connecting block 5. The push plate 901 pushes the slider 904 to slide on the slide rod 7 through the push rod 905, and the first spring 903 is used for buffering.
[0029] The upper end of the limiting rod 10 extends to the outside of the rotating column 12, and the side surface of the limiting rod 10 is slidably connected to the inner wall of the rotating column 12. The sliding rod 15 is inserted through the limiting rod 10.
[0030] The first spring 903 is sleeved outside the slide rod 7, and the third spring 14 is sleeved outside the limiting rod 10. The slide rod 7 limits the first spring 903, making it extend and retract stably and preventing it from deviating.
[0031] Mounting holes are provided at the four corners of the side surfaces of the first positioning piece 1 and the second positioning piece 2. The inner wall of the mounting hole is fixedly connected with an internal thread, and a screw is installed through the mounting hole.
[0032] The limiting block 17 has a square cross-section, and the limiting cap 3 has a circular cross-section. The square limiting block 17 can prevent the sliding rod 7 from rotating with the limiting cap 3 when the limiting cap 3 is rotated.
[0033] The slide rod 7 has a square cross-section, and the side surface of the mounting ring 13 is slidably connected to the inner wall of the insertion rod 15.
[0034] Working principle: During use, after the device is installed, when the rotation force is large, the connecting block 5 will move, thereby squeezing the push plate 901, which in turn pushes the push rod 905 to move. The push rod 905 pushes the slider 904 to slide on the slide rod 7. The slider 904 compresses the first spring 903, thus providing cushioning. When the buffer assembly 9 needs to be replaced, the limit cap 3 is removed, thereby releasing the limit cap 3 from the slide rod 7 and the limit block 17, making it convenient to replace the buffer assembly 9 as a whole. When it is necessary to separate the first positioning piece 1 and the second positioning piece 2, the operator can pull the limit rod 10, which moves the mounting ring 13 upward to compress the third spring 14. Then, the limit rod 10 drives the insertion rod 15 to slide, thereby releasing the limit of the insertion rod 15 on the rotating column 12. Then, the rotating column 12 is pulled out, thereby separating the first positioning piece 1 for easy replacement.
[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
