However, existing hinges are complex, time-consuming, and inconvenient to install and remove.

[0030] To this end, the embodiment of the present application provides a new design structure of an American damping hinge. Based on this, the connection structure hinged to the hinge cup structure can be quickly installed on the hinge arm structure, as described below.

[0031] Hereinafter, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be noted that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0032] Example 1

[0033] Referring to Figures 1 and 2, the American-style damping hinge with quick disassembly and assembly may include a hinge cup structure 1 and a hinge arm structure 2. The hinge cup structure 1 and the hinge arm structure 2 are hinged together; the hinge cup structure 1 can be quickly installed on the hinge arm structure 2 and quickly separated from the hinge arm structure 2, thereby achieving quick assembly and disassembly.

[0034] The following introduces the respective structures and coordination relationships of the hinge cup structure 1 and the hinge arm structure 2.

[0035] The hinge cup structure 1 can be fixedly installed on a door or a door frame.

[0036] The hinge arm structure 2 is hinged to the hinge cup structure 1 and can be fixedly installed on the door frame or the door.

[0037] The hinge arm structure 2 includes a first connecting plate 21 and a second connecting plate 22 .

[0038] The first connecting plate 21 extends outward from the end portion close to the hinge cup structure 1 to form a first connecting portion 211 , and the first connecting plate includes a top plate and first side plates located on both sides of the top plate, and the top plate and the two first side plates form a sliding groove.

[0039] The second connecting plate 22 includes a bottom plate, second side plates located on both sides of the bottom plate and facing upward, and fixing portions located on both ends of the bottom plate and facing downward.

[0040] Wherein, in the assembled state, the end of the first connecting portion 211 extends into the hinge cup structure 1 and is hinged to the hinge cup structure 1. The second connecting plate 22 is inserted into the sliding groove of the first connecting plate 21, and the second connecting plate 22 and the first connecting plate 21 are fixedly connected together by at least one connecting portion. When at least one connecting portion is disassembled, the second connecting plate 21 is disengaged from the sliding groove under the action of external force, so that the first connecting plate 21 is separated from the second connecting plate 22. The user can first fix the second connecting plate 22 on the door or door frame, and then insert the second connecting plate 22 into the sliding groove of the first connecting plate 21, and fix them together through at least one connecting portion, thereby realizing the rapid installation of the American damping hinge. Under the action of external force, when at least one connecting portion is disassembled and the second connecting plate 22 is disengaged from the sliding groove, the user can quickly remove the door from the corresponding door frame.

[0041] In an optional embodiment, the at least one connecting portion includes an adjusting screw 231 .

[0042] Correspondingly, a first through hole 212 is provided at one end of the first connecting plate 21 close to the hinge cup structure 1 . A U-shaped hole 221 is provided at one end of the second connecting plate 22 close to the hinge cup structure 1 .

[0043] The adjusting screw comprises a nut and a threaded rod connected in sequence, with a circumferential groove formed at the bottom of the threaded rod. The nut and threaded rod can be made of steel, aluminum, or stainless steel. The diameter and length of the threaded rod should be designed based on the required adjustment range and are not limited here. The shape and size of the circumferential groove should match the shape and size of the U-shaped hole 221.

[0044] The first through hole 212 and the U-shaped hole 221 are positioned correspondingly to allow the adjusting screw 231 to pass through. The threaded rod passes through the first through hole 212 , and the peripheral groove and the U-shaped hole 221 are rotatably buckled.

[0045] During installation, a person skilled in the art can first insert the adjusting screw 231 through the first through hole 212 so that the second connecting plate 22 fits tightly against the first connecting plate 21, then insert the circumferential groove of the adjusting screw 231 into the U-shaped hole 221, rotate the adjusting screw 231 so that the circumferential groove and the U-shaped hole 221 snap together, and adjust the adjusting screw 231 as needed to optimize the vertical position of the first connecting plate 21 and the second connecting plate 22. The adjusting screw 231 can be adjusted using a screwdriver or a wrench, and the first through hole 212 and the U-shaped hole 221 can be machined into different shapes to improve the connection strength. The adjusting screw 231 can be made of rust-proof material to extend its service life. In this embodiment, the vertical position between the first connecting plate 21 and the second connecting plate 22 can be adjusted by rotating and adjusting the adjusting screw 231, thereby quickly adjusting the relative positions of the two during installation.

[0046] In an optional embodiment, the at least one connecting portion includes an eccentric adjustment rivet 241. The eccentric adjustment rivet 241 can be made of steel, stainless steel or other metals, which are not limited herein.

[0047] Correspondingly, a waist-shaped hole 213 is provided at one end of the first connecting plate 21 away from the hinge cup structure 1. A second through hole 222 is provided at one end of the second connecting plate 22 away from the hinge cup structure 1.

[0048] The eccentric adjustment rivet 241 includes a head, a middle portion, and an eccentric head connected in sequence. The head may be provided with anti-slip grooves to increase friction during installation, the middle portion may be provided with a spring to increase the connection strength with the waist-shaped hole 213, and the eccentric head may be provided with a sealing ring to prevent dust from entering.

[0049] The middle portion is movably clamped in the waist-shaped hole 213 , and the eccentric head passes through the second through hole 222 , so that the first connecting plate 21 and the second connecting plate 22 are relatively displaced along the direction of the waist-shaped hole 213 .

[0050] Specifically, during installation, the relevant technician inserts the middle portion of the eccentric adjustment rivet 241 into the waist-shaped hole 213 of the first connecting plate 21, and the eccentric head of the eccentric adjustment rivet 241 passes through the second through hole 222 of the second connecting plate 22. The technician uses an installation tool to rotate the head of the eccentric adjustment rivet 241 so that the eccentric head moves in the second through hole 222, observes the relative position of the door and the door frame, and makes adjustments as needed. It should be noted that before installing the eccentric adjustment rivet 241, the waist-shaped hole 213 and the second through hole 222 should be cleaned first. When installing the eccentric adjustment rivet 241, do not damage it. When adjusting the eccentric adjustment rivet 241, do not use excessive force to avoid damaging the door or door frame.

[0051] The waist-shaped hole 213 and the second through-hole 222 correspond in position to accommodate the eccentric adjustment rivet 241. The second through-hole 222 accommodates the eccentric head of the eccentric adjustment rivet 241, while the waist-shaped hole 213 accommodates the middle portion of the eccentric adjustment rivet 241. By rotating and adjusting the eccentric adjustment rivet 241, the relative horizontal position of the first connecting plate 21 and the second connecting plate 22 can be adjusted, thereby slightly adjusting the relative position of the door and door frame.

[0052] In an optional embodiment, the eccentric adjustment rivet 241 is of eccentric cam type, with a cross groove provided on the top.

[0053] In an optional embodiment, the first connecting plate 21 includes a recessed portion 214 , and the recessed portion 214 is located at an end of the first connecting plate 21 away from the hinge cup structure 1 .

[0054] The waist-shaped hole 213 is provided in the recessed portion 214, which is used to accommodate the head of the eccentric adjustment rivet 241. The recessed portion 214 has a height greater than or equal to the height of the head of the eccentric adjustment rivet 241. In this optional embodiment, the recessed portion 214 provides a space for the head of the eccentric adjustment rivet 241 to prevent it from protruding from the horizontal plane of the first connecting plate 21.

[0055] Among them, the recessed portion 214 is circular or rectangular, and its shape should match the head of the eccentric adjustment rivet 241. Its diameter or length should be greater than or equal to the diameter or length of the head of the eccentric adjustment rivet 241, and its depth should be greater than or equal to the thickness of the head of the eccentric adjustment rivet 241.

[0056] The recessed portion 214 can be formed by stamping, drilling, or other processing methods, and can be made of the same material as the first connecting plate 21, such as steel, aluminum, or plastic. This is not limited here. In this embodiment, the recessed portion 214 makes the hinge structure more compact, saves space, and improves the appearance of the hinge structure.

[0057] In an optional embodiment, the second connecting plate 22 includes a raised portion 223 disposed at an end away from the hinge cup structure 1. The raised portion 223 can be made of the same material as the second connecting plate 22, such as steel, aluminum, or plastic. The raised portion 223 can be formed by stamping, welding, or other processing methods, which are not limited herein.

[0058] The second through hole 222 is provided in the middle of the protrusion 223. In this embodiment, by providing the protrusion 223 on the second connecting plate 22 to match the recess 214 of the first connecting plate 21, the first connecting plate 21 and the second connecting plate 22 can be fitted together, and the hinge structure is more firm and stable.

[0059] The structure of the hinge cup structure 1 is introduced below.

[0060] In an optional embodiment, the hinge cup structure 1 includes: a torsion spring 12 , a hinge cup body 11 , and a receiving space 111 .

[0061] The receiving space 111 can be formed by drilling, stamping or other processing methods, which are not limited here. The side walls of the receiving space 111 are respectively provided with a square hole 1111 and a special-shaped hole 1112.

[0062] The torsion spring 12 includes a torsion spring body and a claw and an extension portion extending from the torsion spring body. The torsion spring 12 can be made of an elastic material, such as steel, stainless steel or spring steel, and its shape can be spiral or cylindrical. The diameter, length and number of turns of the torsion spring 12 should be designed according to the torque required to be provided, and are not limited here. The claw can be made of the same material as the torsion spring 12, and its shape should match the square hole 1111. The claw can be fixed in the square hole 1111 by welding, riveting or other means. The extension portion passes through the special-shaped hole 1112 and can be abutted against one end of the first connecting portion 211. Its shape should match the special-shaped hole 1112, and its length should be greater than or equal to the thickness of the first connecting plate 21.

[0063] Specifically, when installing, relevant technicians in this field install the hinge cup structure 1 and the first connecting plate 21 on the door or door frame, insert the claw of the torsion spring 12 into the square hole 1111 of the first connecting plate 21, and pass the extended part of the torsion spring 12 through the special-shaped hole 1112 of the first connecting plate 21.

[0064] When the angle between the hinge cup structure 1 and the first connecting plate 21 changes, the extended portion of the torsion spring 12 abuts against one end of the first connecting plate 21, exerting a force on the first connecting plate 21. This force provides a damping effect, preventing the door or door frame from opening or closing suddenly. In this embodiment, the use of a torsion spring allows for smoother and safer opening and closing of the door or door frame.

[0065] In an optional embodiment, the hinge cup structure 1 further includes a damping device 13, which includes a damper 131. The damper 131 is located in the receiving space 111, with one end facing the inner wall of the receiving space 111 and the other end facing one end of the first connecting portion 211. The damper 131 can be a hydraulic damper, a pneumatic damper, or a magnetic damper, and can be composed of components such as a cylinder, a piston, a piston rod, and a seal, all of which are not limited herein.

[0066] When the angle between the hinge cup structure 1 and the first connecting portion 211 changes, the piston rod of the damper 131 moves, and the ends of the damper 131 respectively abut against the inner wall of the receiving space 111 and the end of the first connecting portion 211, thereby generating a damping force. In this embodiment, the damping device 13 can provide a damping effect to prevent the door or door frame from opening or closing suddenly.

[0067] In an optional embodiment, the damping device 13 further includes: a pressure hoop 132 and a switch 133 .

[0068] The pressure band 132 can be circular or rectangular, matching the shape of the receiving space 111. Its diameter or length should be less than or equal to that of the receiving space 111, and its height should be greater than or equal to the maximum stroke of the damper 131. It can be made of steel, aluminum, or plastic, without limitation. When the door or door frame opens or closes, the piston rod of the damper 131 moves, pushing the pressure band 132. The movement of the pressure band 132 triggers the switch 133, which outputs a switching signal.

[0069] The clamp 132 is fixed above the receiving space 111 and forms a receiving space with the receiving space 111, which is used to limit the range of motion of the damper 131. The clamp 132 can be fixed to the receiving space 111 by a threaded connection or a snap connection. The switch 133 can be fixed to the clamp 132 or to the wall of the receiving space 111 by screws or welding.

[0088] The first through hole 311' is provided in the middle of the raised portion 31' to allow the hinge arm base plate 3' to fit snugly with the bent portion 21'. In this embodiment, by providing the raised portion 31' on the hinge arm base plate 3' to mate with the recessed portion 212' of the bent portion 21', the connection structure 2' and the hinge arm base plate 3' can be fitted together, making the hinge structure more secure and stable.

[0089] In an optional embodiment, the hinge arm base plate 3 ′ further includes fixing portions 32 ′ provided at four corners, and the fixing portions 32 ′ are used to be inserted into a door or a door frame so as to fix the hinge arm base plate 3 ′ to the door or the door frame.

[0090] The dimensions of the fixing portion 32' should match the thickness of the door or doorframe, and sufficient clearance should be left for easy insertion and removal. The thickness of the fixing portion 32' should be strong enough to support the weight of the door or doorframe. It can be made of plastic, metal, or wood. The selected material should be strong, durable, and resistant to corrosion and wear. It is important to note that before installing the fixing portion 32', ensure that the surface of the door or doorframe is clean and dry, and use fasteners of the appropriate size to avoid damaging the door or doorframe.

[0091] In an optional embodiment, in the connection structure 2 ′, the protrusion and the hinge arm mounting area 211 ′ form a guide groove.

[0092] Correspondingly, the hinge arm bottom plate 3 ′ includes a bottom plate and side plates located on both sides of the bottom plate. The side plates are vertically arranged on the bottom plate, and the side plates include a first section and a second section.

[0093] The first section is away from the hinge cup structure 1', and the lateral end surface of the first section is used to fit with the inner wall of the sliding groove 2111'.

[0094] The second section is close to the hinge cup structure 1', the lateral end surface of the second section is spaced apart from the inner wall of the slide groove 2111', and a lateral flange is provided on the lateral end surface of the second section, and the lateral flange is used to be inserted into the guide groove.

[0095] Specifically, during installation, relevant technical personnel in this field first install the connecting structure 2' into place, insert the first section of the side plate of the hinge arm base plate 3' into the sliding groove 2111', and adjust the position of the hinge arm base plate 3' to make it flush with the connecting structure 2'.
