DETAILED DESCRIPTION

[0030] like Figure 1 , 7-10, a combined type copier metal hinge, comprising a first gasket 1, a card cavity 2 is fixedly connected to the first gasket 1, a first connector 3 is slidably connected to the first gasket 1, an end of the first connector 3 close to the card cavity 2 is slidably connected to the card cavity 2 through a detachable adjustment component, and an end of the first connector 3 away from the card cavity 2 is rotatably connected to a rotating shaft 4;

[0031] The outer periphery of the rotating shaft 4 is symmetrically connected with a second connector 5, and the end of the second connector 5 away from the rotating shaft 4 is limitedly provided with a second gasket 6; the second gasket 6 and the opposite end surfaces of the second connector 5 are embedded with an annular groove 601 for the coaxial rotation of the two groups of second connectors 5, and the two sides of the annular groove 601 are symmetrically connected and provided with fourth limiting sliding grooves 602 for the relative movement of the two groups of second connectors 5, and the two sides of the two groups of second connectors 5 that are opposite to each other are symmetrically connected with limiting components for limiting the coaxial rotation of the two groups of second connectors 5 relative to the second gasket 6;

[0032] When the end of the limiting assembly is matched with the second gasket 6 , the end of the second connector 5 is located at a side of the annular groove 601 relatively away from the two groups of fourth limiting sliding grooves 602 .

[0033] In this example, preferably, the first gasket 1 is symmetrically provided with multiple groups of threaded holes or through holes on both sides of the card cavity 2, and the second gasket 6 is also provided with multiple groups of threaded holes or through holes at the end away from the second connecting head 5. The second gasket 6 and the first gasket 1 can be respectively connected to the cover plate and the body of the copier by screws or pins, and the relative angle change between the first gasket 1 and the second gasket 6 can be formed by rotating the rotating shaft 4 on the first connecting head 3.

[0034] In this embodiment, preferably, the second gasket 6 is an "L"-shaped structural profile, one side end face of the second gasket 6 is opposite to the end faces of the two groups of second connecting heads 5, and the annular groove 601 is embedded in the center of the end face of the second gasket 6, and the two sides of the end of the second connecting head 5 are movably connected to the two sides of the annular groove 601, and the two sides of the ends of the two groups of second connecting heads 5 cooperate to form a spherical protrusion, so that when the two groups of second connecting heads 5 are fitted together, the ends can slide on the annular groove 601, thereby forming relative rotation between the two groups of second connecting heads 5 and the second gasket 6.

[0035] In this embodiment, preferably, the middle portion of the rotating shaft 4 is arranged in a spline shape, and when the two sets of second connectors 5 are fitted together, the relatively close sides are adapted to the rotating shaft 4, and the two ends of the rotating shaft 4 and the two sides of the end of the first connector 3 are rotatably connected.

[0036] In this embodiment, preferably, the detachable adjusting component can adopt a cylinder, a hydraulic cylinder or an electric telescopic push rod, etc., to adjust the relative position of the first connecting head 3 and the card cavity 2 by telescopic means. One end of the detachable adjusting component is assembled and connected to the card cavity 2, and the other end is detachably connected to the first connecting head 3 by bolt connection or clamping.

[0037] In this embodiment, preferably, the limiting component can adopt a snap or bolt connector, and the end of the limiting component is movably adapted to the second gasket 6. The limiting component can limit the relative rotation of the second connector 5 and the second gasket 6.

[0038] In this embodiment, the first gasket 1 and the second gasket 6 are respectively fixed on the cover plate and the shell of the copier, and the relative angle between the cover plate and the shell can be changed by rotating the rotating shaft 4; the detachable adjustment component can be appropriately adjusted according to the copy thickness, so as to be suitable for a variety of copy materials; when it is necessary to separate the cover plate and the shell, the relative limit of the second gasket 6 by the limiting component is removed, and the second connecting head 5 and the second gasket 6 can be relatively rotated, and the end of the second connecting head 5 rotates on the annular groove 601. When the two sides are respectively rotated to align with the fourth limiting sliding grooves 602 on both sides of the annular groove 601, the two groups of second connecting heads 5 can move away from each other respectively, and the second connecting head 5 can move away from each other respectively. The ends of the two connecting heads 5 slide on the fourth limiting slide groove 602, so that the two groups of second connecting heads 5 can be disengaged from the state of the clamping shaft 4; this connection method is flexible and simple, and the limiting component can cooperate during the clamping to stably prevent the second gasket 6 and the second connecting head 5 from rotating relative to each other, so that the annular groove 601 can be used to limit the two groups of second connecting heads 5 to be relatively far apart, so that the cover and the shell of the copier are more stable when they rotate relative to each other, and when disassembly is required, it is only necessary to control the limiting component to disengage from the relative limitation of the second gasket 6, so that the second gasket 6 and the second connecting head 5 can be relatively rotated, so that the two groups of second connecting heads 5 can achieve a detachable effect.

[0039] like Fig.10 As shown, the fourth limiting groove 602 is symmetrically and parallelly arranged on both sides of the annular groove 601, and the inner diameter of the fourth limiting groove 602 and the annular groove 601 are the same and are connected to each other, and the ends of the second gasket 6 close to the second connector 5 are symmetrically embedded with matching grooves 603, and the matching grooves 603 and the fourth limiting groove 602 are arranged in parallel, and the end of the limiting component and the matching groove 603 are movably adapted.

[0040] In this embodiment, preferably, through the setting of the annular groove 601, the two groups of second connecting heads 5 can be stably limited in the annular groove 601. The ends of the two groups of second connecting heads 5 away from the second gasket 6 are clamped on the periphery of the rotating shaft 4. Therefore, the two groups of second connecting heads 5 cannot move away from each other or move synchronously in parallel, and can only rotate on the annular groove 601. The fourth limiting slide groove 602 is set on both sides of the annular groove 601. In this way, when the two groups of second connecting heads 5 rotate from a state parallel to the fourth limiting slide groove 602 to a relatively vertical state, the ends of the two groups of second connecting heads 5 can smoothly transition from the annular groove 601 to the fourth limiting slide groove 602. At this time, the two groups of second connecting heads 5 move away from each other, so that the second connecting head 5 can be removed from the rotating shaft 4, and the matching limiting component can limit the relative rotation of the second gasket 6 and the second connecting head 5, so that the second connecting head 5 will not be removed and the placement is stable during relative rotation.

[0041] like Figure 8-9 As shown, a key groove 501 is embedded in the side surface of one end of the second connector 5, and the key groove 501 is snap-fitted with the surface of the rotating shaft 4. A second slider 505 is connected to the end of the second connector 5 away from the rotating shaft 4. The second slider 505 is connected on both sides of the end of the second connector 5, and the two groups of second sliders 505 relative to the second connectors 5 are spliced ​​into a boss structure, and the two groups of second sliders 505 relative to the second connectors 5 are movably connected in the annular groove 601.

[0042] In this embodiment, preferably, the key slot 501 radially penetrates the second connector 5, the end of the second connector 5 close to the rotating shaft 4 is chamfered, and the two groups of second connectors 5 form a semicircular structure at the opposite ends. The two groups of second connectors 5 slide relative to each other through the second slider 505, the annular groove 601 and the fourth limiting slide groove 602, and the two groups of second connectors 5 can be rotated relative to the second gasket 6 together, or the two groups of second connectors 5 can be relatively close or far away from each other through the sliding cooperation of the second slider 505 and the fourth limiting slide groove 602, and the installation and disassembly are flexible and convenient, and there is no need to use matching tools for disassembly, and the stability of use will not be affected by the installation method.

[0043] like Figure 8-10As shown, the limiting component is embedded in one end of the second connecting head 5 close to the second gasket 6, and the limiting components on the two groups of second connecting heads 5 are respectively located on the relatively opposite sides of the two groups of second connecting heads 5. The limiting component includes a second clamping plate 503, and a third limiting groove 502 is embedded in the second connecting head 5. The second clamping plate 503 is slidably connected in the third limiting groove 502 through a second spring 504. The second clamping plate 503 extends out of the third limiting groove 502 away from the end of the third limiting groove 502 and is movably adapted to the mating clamping plate 603.

[0044] In this embodiment, preferably, the two sides of the second clamping plate 503 are slidably matched through the guide rails and the third limiting slide groove 502, and multiple groups of second springs 504 are connected between the end of the second clamping plate 503 extending into the third limiting slide groove 502 and the inner wall of the third limiting slide groove 502. When the second spring 504 is in a normal state, the end of the second clamping plate 503 extends out of the third limiting slide groove 502, and the second clamping plate 503 compresses the second spring 504, so that the end of the second clamping plate 503 can be removed from the matching clamping groove 603.

[0045] like Figure 1-5 As shown, the first gasket 1 is embedded with a first limiting groove 101, the first connecting head 3 and the first gasket 1 are fitted together, and the first connecting head 3 is fixedly connected with a first slider 303 that is slidably adapted to the first limiting groove 101, the card cavity 2 is covered at the outer periphery of the end of the first connecting head 3, one end of the first connecting head 3 extends out of the card cavity 2, and the other end is connected to the card cavity 2 through a detachable adjustment component, and the top of the card cavity 2 is connected with a limiting wheel 201 that movably resists the surface of the first connecting head 3.

[0046] In this embodiment, preferably, the first connector 3 is slidably fitted on the surface of the first gasket 1, and the adjustment rod 202 in the card cavity 2 presses the first connector 3 tightly against the first gasket 1, thereby preventing the first connector 3 from shaking when moving and extending. The card cavity 2 can be fixed to the first gasket 1 by welding or bolting, and the detachable adjustment component is connected to the end of the card cavity 2 away from the first connector 3. By rotating the detachable adjustment component, the extension length of the first connector 3 from the card cavity 2 can be stably adjusted, so as to facilitate flexible adjustment according to the copy thickness.

[0047] like Figure 4-5As shown, the end of the first connecting head 3 away from the card cavity 2 is embedded with a bayonet 301, the rotating shaft 4 is rotatably connected in the bayonet 301 through a damping bearing 302, the end of the first connecting head 3 away from the rotating shaft 4 is embedded with a slot 304, the end of the detachable adjustment component is movably connected in the slot 304, and the second limiting slots 305 are symmetrically embedded on both sides of the opening of the slot 304, and the first clamping plate 306 is slidably connected in the second limiting slot 305, one end of the first clamping plate 306 extends into the slot 304, and the other end is connected to the second limiting slot 305 through a first spring 308.

[0048] In the present embodiment, preferably, when the end of the detachable adjusting component is engaged in the slot 304, by controlling the extension and retraction of the detachable adjusting component, the first connecting head 3 can be driven to slide on the first gasket 1, and the first clamping plate 306 cooperates to clamp the end of the detachable adjusting component in the slot 304, thereby preventing it from falling off and facilitating disassembly and maintenance when necessary.

[0049] like Figure 4-5 As shown, a guide block 307 is fixedly connected to the surface of the first clamping plate 306, and an adjusting rod 202 is fixedly connected to the end of the clamping cavity 2 away from the first connecting head 3. The adjusting rod 202 and the guide block 307 are correspondingly arranged and movably adapted. After the guide block 307 and the adjusting rod 202 are fitted together, as the guide block 307 moves toward the end of the clamping cavity 2 away from the first connecting head 3, the guide blocks 307 on the two groups of first clamping plates 306 move away from each other.

[0050] In the present embodiment, preferably, when the first connector 3 is controlled to move relative to the card cavity 2 by the detachable adjusting component, if disassembly is required, the first connector 3 can be retracted to the inner end of the card cavity 2 by the detachable adjusting component, so that the guide block 307 and the first protrusion 204 gradually approach and fit together, and as the first protrusion 204 squeezes the guide block 307, the two groups of guide blocks 307 and the first clamping plate 306 can be pushed in opposite directions, thereby disengaging from the clamping restriction on the end of the detachable adjusting component.

[0051] In this embodiment, preferably, the guide block 307 adopts a triangular prism structure, the inclined surfaces of the two sets of guide blocks 307 are arranged oppositely, the adjustment rod 202 adopts a support rod with a ball embedded in the end, and the end of the adjustment rod 202 and the inclined surface of the guide block 307 are arranged correspondingly. In this way, stable pushing and flexible disassembly can be achieved.

[0052] like Figure 3-5As shown, the detachable adjustment component includes an adjustment rod 202, and the adjustment rod 202 movably penetrates the end of the card cavity 2 through a threaded fit. One end of the adjustment rod 202 is rotatably connected to a connecting plate 203 through a bearing, and the connecting plate 203 is movably connected in the card slot 304. The other end of the adjustment rod 202 is fixedly connected to a handle.

[0053] In this embodiment, preferably, the connecting plate 203 is connected in the card slot 304 and is clamped by the first clamping plates 306 on both sides. As the handle is turned to drive the adjusting rod 202 to move in the card cavity 2, the first connecting head 3 can be driven to move stably.

[0054] like Figure 1 , 4 As shown in 6, the damping bearing 302 includes a bearing cavity 321 fixedly connected to the end of the first connector 3, the bearing cavity 321 is an annular cavity structure, the inner ring of the bearing cavity 321 is rotatably embedded with a rotating inner ring 322, the rotating inner ring 322 is sleeved and fixed on the end of the rotating shaft 4, and the outer periphery of the rotating inner ring 322 is fixedly connected with multiple groups of blades 323, and a rotating clip 324 is connected to the inner wall of the bearing cavity 321 opposite to the end of the blade 323, and the rotating clip 324 and the end of the blade 323 are movably snap-fitted, and the bearing cavity 321 is filled with a non-Newtonian fluid.

[0055] In this embodiment, preferably, the rotating clamping piece 324 can be composed of two groups of pads symmetrically hinged on the bearing cavity 321, and a torsion spring is connected between the end of the pad and the bearing cavity 321. The two groups of pads are arranged relatively parallel and the gaps between the two groups of pads are adapted to the thickness of the blade 323.

[0056] In this embodiment, preferably, when the rotating shaft 4 rotates relatively, it drives the rotating inner ring 322 to rotate. When the rotating inner ring 322 and the blade 323 rotate relatively, it is necessary to overcome the resistance of the non-Newtonian fluid filled in the bearing cavity 321, and be able to avoid sudden rotation, so as to avoid damage caused by rapid shutdown of the copying equipment. At the same time, when the rotating inner ring 322 and the bearing cavity 321 rotate relatively, the blade 323 pushes a group of pads to rotate, thereby disengaging from the clamping of two adjacent groups of pads, and continuing to rotate can be clamped between the other two adjacent groups of pads. In this way, the relative angle stability of the rotating parts on both sides when the rotating shaft 4 rotates can be further improved.

[0057] Working principle: When in use, the first gasket 1 and the second gasket 6 are fixed on the cover and the shell of the copier respectively, and the relative angle between the cover and the shell can be changed by rotating the rotating shaft 4; the detachable adjustment component can be appropriately adjusted according to the copy thickness, which is convenient for applying to a variety of copy materials; when it is necessary to separate the cover and the shell, the relative limit of the second gasket 6 by the limiting component is removed, and the second connector 5 and the second gasket 6 can be relatively rotated, and the end of the second connector 5 rotates on the annular groove 601. When the two sides are respectively rotated to align with the fourth limiting slide grooves 602 on both sides of the annular groove 601, the two groups of second connectors 5 can be respectively relative to each other. The second connection head 5 is then disengaged from the second connection head 5 by means of the fourth limiting sliding groove 602. This allows the two groups of second connection heads 5 to be disengaged from the state of being engaged with the rotating shaft 4. This connection method is flexible and simple. When engaged, the limiting component cooperates to stably prevent the second gasket 6 and the second connection head 5 from rotating relative to each other. This allows the annular groove 601 to be used to limit the two groups of second connection heads 5 from being relatively separated. This makes the cover plate and the housing of the copier more stable when they rotate relative to each other. When disassembly is required, it is only necessary to control the limiting component to disengage from the relative limiting of the second gasket 6, so that the second gasket 6 and the second connection head 5 can be relatively rotated, thereby the two groups of second connection heads 5 can be disengaged. The effect of detachability is achieved; the two groups of second connecting heads 5 form relative sliding through the second slider 505, the annular groove 601 and the fourth limiting slide groove 602, and the two groups of second connecting heads 5 can be rotated together relative to the second gasket 6, or the two groups of second connecting heads 5 can be slidably matched with the second slider 505 and the fourth limiting slide groove 602 to form relative proximity or distance. The installation and disassembly are flexible and convenient, and there is no need to use supporting tools for disassembly, and the stability of use will not be affected by the installation method; when the end of the detachable adjustment component is matched in the card slot 304, the first connecting head 3 can be driven by controlling the extension and contraction of the detachable adjustment component. The first gasket 1 slides on the first card plate 306, and the first card plate 306 cooperates to clamp the end of the detachable adjustment component in the card slot 304, so as to prevent it from falling off, and it can also be convenient for disassembly and maintenance when necessary; when the first connector 3 is controlled to move relative to the card cavity 2 by the detachable adjustment component, if it needs to be disassembled, the first connector 3 can be retracted to the inner end of the card cavity 2 by the detachable adjustment component, so that the guide block 307 and the first protrusion 204 gradually approach and fit together, and as the first protrusion 204 squeezes the guide block 307, the two groups of guide blocks 307 and the first card plate 306 can be pushed in opposite directions, thereby breaking away from the clamping restriction on the end of the detachable adjustment component;When the rotating shaft 4 rotates relatively, the rotating inner ring 322 is driven to rotate. When the rotating inner ring 322 and the blade 323 rotate relatively, it is necessary to overcome the resistance of the non-Newtonian fluid filled in the bearing cavity 321, and to avoid sudden rotation, so as to avoid damage caused by rapid shutdown of the copying device. At the same time, when the rotating inner ring 322 and the bearing cavity 321 rotate relatively, the blade 323 pushes a group of pads to rotate, thereby breaking away from the clamping of two adjacent groups of pads, and continuing to rotate can be clamped between the other two adjacent groups of pads. In this way, the relative angle stability of the rotating parts on both sides when the rotating shaft 4 rotates can be further improved. ;
