Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to an adjustable hinge structure and hinge. Background Technology

[0002] Door hinges, as a common connecting component, are widely used in furniture, cabinets, building doors and windows, and various appliance cabinet doors. Currently, most door hinges on the market use a fixed structure. After installation, the maximum opening angle of the door is determined, and this angle is usually greater than 90°. If the door is installed against a wall or there are obstacles in the door's opening direction, the door panel is very likely to collide with the wall or obstacle when fully opened. This can not only cause damage to the door panel, wall, or hinge itself, but long-term impact can also lead to loosening of the connection and affect its service life. To address this problem, existing technologies typically use custom-made small-angle hinges or adjust the door panel installation position to avoid this issue. However, this requires replacing the hinges or other parts, which is cumbersome and costly, and cannot be flexibly adjusted according to the actual installation environment. Utility Model Content

[0003] The main purpose of this utility model is to provide an adjustable hinge structure and hinge to solve the problem that the maximum opening angle of existing door hinges cannot be flexibly adjusted.

[0004] To achieve the above objectives, this utility model proposes an adjustable hinge structure, comprising: a drive arm, a linkage arm, and a limiting member; one end of the drive arm is used to connect to a first fixing member and the other end is used to connect to a second fixing member, and one end of the linkage arm is used to connect to the first fixing member and the other end is used to connect to the second fixing member, so that the first fixing member moves relative to the second fixing member under the combined action of the drive arm and the linkage arm; the limiting member is movably disposed between the drive arm and the linkage arm, used to avoid or block the linkage arm, so that the first fixing member opens to different angles relative to the second fixing member.

[0005] Optionally, the limiting member forms a limiting portion, and the linkage arm forms an abutting portion; the limiting portion avoids or presses against the abutting portion to limit the opening angle of the first fixing member relative to the second fixing member.

[0006] Optionally, the limiting member has a recess, which is disposed adjacent to the limiting portion and forms a stepped structure; when the limiting portion avoids the abutting portion, the abutting portion enters the recess.

[0007] Optionally, the limiting member has a protruding actuating member on the side opposite to the limiting portion, and the driving arm has a sliding track along the moving direction of the limiting member, so that the limiting member can be movably disposed on the sliding track by the actuating member.

[0008] Optionally, the actuating member has a toggle portion, and the actuating member is at least partially exposed in the sliding track, with the portion of the actuating member exposed in the sliding track forming the toggle portion.

[0009] Optionally, the actuating part has a locking head, which is spaced apart from the limiting member to form a limiting groove, and the actuating member is movably locked in the sliding track through the limiting groove.

[0010] This utility model also proposes a hinge, including a hinge cup, a hinge body, and the aforementioned adjustable hinge structure. The hinge cup is rotatably connected to one end of the drive arm and one end of the linkage arm, respectively. The hinge body is rotatably connected to the other end of the drive arm and the other end of the linkage arm, respectively. The hinge cup is opened to different angles relative to the hinge body by the combined action of the drive arm and the linkage arm.

[0011] Optionally, a damper is included, the damper being disposed on the hinge, and the movable end of the damper being drive-connected to the linkage arm.

[0012] Optionally, it also includes a mounting base and a pusher. The mounting base has a mounting cavity, and the pusher is movably disposed at the opening end of the mounting cavity. One end of the pusher is connected to the linkage arm for transmission. The damper is disposed in the mounting cavity, and the movable end of the damper can be compressed by the pusher.

[0013] Optionally, one end of the pusher is provided with a groove, and one end of the linkage arm provided with a protrusion is provided at the hinge body. The protrusion is engaged in the groove so that the linkage arm drives the pusher to move.

[0014] In this invention, the adjustable hinge structure includes a drive arm, a linkage arm, and a limiting member. One end of the drive arm connects to a first fixing member, and the other end connects to a second fixing member. One end of the linkage arm connects to the first fixing member, and the other end connects to the second fixing member. The limiting member is movably positioned between the drive arm and the linkage arm. When applied to a hinge, the positional relationship between the drive arm and the linkage arm changes during the opening of the hinge cup relative to the hinge body. Therefore, when a large opening angle is required, the limiting member is moved to avoid obstructing the linkage arm. Since there is no obstruction between the linkage arm and the drive arm, the hinge can open to a larger angle. When a small opening angle is required, the limiting member is moved to block the movement of the linkage arm, so the hinge can only open to a relatively small angle. This allows for flexible adjustment of the hinge's opening angle according to the actual installation environment. Furthermore, this solution has a simple structure, and no reassembly is required when switching between different angles. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0020] See Figures 1 to 11 As shown in one embodiment of the present invention, an adjustable hinge structure 10 includes: a drive arm 11, a linkage arm 12, and a limiting member 13; one end of the drive arm 11 is used to connect to a first fixing member and the other end is used to connect to a second fixing member; one end of the linkage arm 12 is used to connect to the first fixing member and the other end is used to connect to the second fixing member; the first fixing member moves relative to the second fixing member under the combined action of the drive arm 11 and the linkage arm 12; the limiting member 13 is movably disposed between the drive arm 11 and the linkage arm 12 to avoid or block the linkage arm 12, so that the first fixing member opens to different angles relative to the second fixing member.

[0021] Specifically, in this embodiment, one end of the drive arm 11 is connected to one end of the linkage arm 12 via a transmission connection. Preferably, in this embodiment, the drive arm 11 and the linkage arm 12 are connected by a U-shaped connecting rod 16. The drive arm 11 and the linkage arm 12 are rotatably connected to the two connecting rods of the U-shaped connecting rod 16, respectively. Further, one end of the drive arm 11 and one end of the linkage arm 12 can be rotatably connected to the first fixed member via the U-shaped connecting rod 16; the other end of the drive arm 11 can be rotatably connected to the second fixed member via the motion shaft (A), and the other end of the linkage arm 12 can be rotatably connected to the second fixed member via the motion shaft (A). Shaft (B) is rotatably connected to the second fixed member. It can be understood that the drive arm 11, the linkage arm 12, the first fixed member, and the second fixed member form a quadrilateral linkage structure. Specifically, during the opening process of the first fixed member relative to the second fixed member, the drive arm 11 rotates counterclockwise and the linkage arm 12 rotates clockwise, with the ends of the drive arm 11 and the linkage arm 12 connected to the first fixed member moving closer to each other; during the closing process, the drive arm 11 rotates clockwise and the linkage arm 12 rotates counterclockwise, with the ends of the drive arm 11 and the linkage arm 12 connected to the first fixed member moving further apart. Based on this principle, a limiting member 13 is provided between the drive arm 11 and the linkage arm 12. The proximity distance between the drive arm 11 and the linkage arm 12 is determined by the movable limiting member 13, thereby achieving different opening angles for the first fixing member relative to the second fixing member. As an example, in this embodiment, the limiting member 13 allows the first fixing member to open to a first angle or a second angle relative to the second fixing member. Specifically, the first angle is 105° and the second angle is 85°. For clarity, the corresponding angles are marked on the surface of the drive arm 11 in the attached drawings of this solution. It can be understood that the specific values ​​of the first angle and the second angle mentioned above or described below are determined according to the actual situation. The angles are determined by the positional relationship between the drive arm 11, the linkage arm 12, and the limiting member 13, and are not limited here.

[0022] It should be noted that the limiting member 13 in this embodiment can be in the form of a slider. The slider has two thicknesses and can slide between the drive arm 11 and the linkage arm 12. When it slides to the thicker area between the drive arm 11 and the linkage arm 12, it restricts the proximity of the two arms, and the first fixing member opens to a second angle relative to the second fixing member. When it slides to the thinner area between the two arms or completely moves out, the two arms can move closer, and the first fixing member opens to a first angle relative to the second fixing member. The limiting member 13 can also be in the form of a pin. The pin is controlled to extend and retract by a button, spring, or screw. When the pin extends and engages between the drive arm 11 and the linkage arm 12, it restricts the proximity of the two arms, and the first fixing member opens to a second angle relative to the second fixing member. When the pin retracts, there is no obstruction between the two arms, and they can move closer, and the first fixing member opens to a first angle relative to the second fixing member. The limiting member 13 can also be in the form of a cam with different radii. It can rotate between the drive arm 11 and the linkage arm 12. When the cam is rotated so that its larger radius is between the drive arm 11 and the linkage arm 12, the proximity of the two arms is limited, and the first fixing member opens to a second angle relative to the second fixing member. When the cam is rotated so that its smaller radius is between the two arms, the two arms can move closer, and the first fixing member opens to a first angle relative to the second fixing member. It is understood that the above description only lists two opening angle states. Furthermore, more opening angles can be achieved by controlling the shape or position of the limiting member 13. For example, by setting multiple different thickness areas on the slider, the slider can be moved to different positions, thereby controlling the distance between the drive arm 11 and the linkage arm 12, allowing the first fixing member to open at different angles relative to the second fixing member. As long as the limiting member 13 can be moved to avoid or block the linkage arm 12, multiple opening angles can be achieved. This embodiment is not limited to this, and all of the above are within the protection scope of this utility model.

[0023] In the technical solution of this utility model, the adjustable hinge structure 10 includes a drive arm 11, a linkage arm 12, and a limiting member 13. One end of the drive arm 11 is used to connect to a first fixing member, and the other end is used to connect to a second fixing member. One end of the linkage arm 12 is used to connect to the first fixing member, and the other end is used to connect to the second fixing member. The limiting member 13 is movably disposed between the drive arm 11 and the linkage arm 12. When applied to the hinge 100, the positional relationship between the drive arm 11 and the linkage arm 12 changes during the opening process of the hinge cup 20 relative to the hinge body 30. Therefore, when a large opening angle is required, the limiting member 13 is moved to avoid the linkage arm 12. Since there is no obstruction between the linkage arm 12 and the drive arm 11, the hinge can be opened to a larger angle. When a small opening angle is required, the limiting member 13 is moved to block the movement of the linkage arm 12. Therefore, the hinge 100 can only be opened to a relatively small angle. This allows for flexible adjustment of the opening angle of the hinge 100 according to the actual installation environment. Moreover, the structure of this solution is simple, and there is no need to disassemble and reassemble when switching between different angles.

[0024] See Figures 1 to 11 As shown, further, in one embodiment of this utility model, the limiting member 13 forms a limiting portion 131, and the linkage arm 12 forms an abutment portion 121; the limiting portion 131 avoids or abuts against the abutment portion 121 to limit the opening angle of the first fixing member relative to the second fixing member. It should be noted that the limiting member 13 in this embodiment is a slider, with the limiting portion 131 protruding from one side of the slider facing the linkage arm 12; the end of the linkage arm 12 connected to the first fixing member forms the abutment portion 121, which is closer to the drive arm 11 than other positions of the linkage arm 12, and the portion connected to the abutment portion 121 extends inwardly at an angle to form a clearance groove. Specifically, the limiting member 13 in this embodiment has a first position and a second position between the drive arm 11 and the linkage arm 12, wherein when the limiting member 13 moves to the first position, the first fixing member can open to a first angle relative to the second fixing member; when the limiting member 13 moves to the second position, the first fixing member can open to a second angle relative to the second fixing member. See also Figure 3 When the limiting member 13 is in the second position, the limiting part 131 is located between the drive arm 11 and the abutment part 121. During the opening process of the first fixing member relative to the second fixing member, the abutment part 121 continuously approaches the drive arm 11 until the abutment part 121 presses against the limiting part 131, preventing the linkage arm 12 from approaching further. At this time, the maximum opening angle of the first fixing member relative to the second fixing member is 85° (second angle); see also Figure 2When the limiting member 13 is in the first position, the limiting part 131 retracts to the clearance groove. Without the obstruction of the limiting part 131, the linkage arm 12 can move closer to the drive arm 11 compared to its position in the second position. At this time, the maximum opening angle of the first fixing member relative to the second fixing member is 105° (the first angle). In this embodiment, by setting the limiting member 13 in the form of a slider, the slider presses against the linkage arm 12 to limit its movement. During use, simply sliding the slider to different positions changes the maximum opening angle, making it convenient for the user.

[0025] See Figures 1 to 11 As shown, further, in one embodiment of this utility model, the limiting member 13 has a recess 132, which is disposed adjacent to the limiting part 131 and forms a stepped structure; when the limiting part 131 avoids the abutting part 121, the abutting part 121 falls into the recess 132. It should be noted that the limiting member 13 in this embodiment is shaped like a trapezoid, with a recess 132 formed on one side of the trapezoid. When the limiting member 13 slides to the first position, the abutting part 121 falls into the recess 132 along the inclined surface of the trapezoid. Further, see... Figure 2 In this embodiment, the shape of the recess 132 fits the outer shape of the abutment portion 121. Thus, when the limiting member 13 is in the first position and the first fixing member is opened to 105° relative to the second fixing member, the abutment portion 121 and the recess 132 fit together. The recess 132 and the abutment portion 121 both play a limiting role, preventing the limiting member 13 from sliding back and forth and causing positional displacement.

[0026] See Figures 1 to 11 As shown, further, in one embodiment of this utility model, a toggle member 14 protrudes from the side of the limiting member 13 opposite to the limiting part 131, and a sliding track 111 is provided on the driving arm 11 along the movement direction of the limiting member 13. The limiting member 13 is movably disposed on the sliding track 111 via the toggle member 14. It should be noted that the limiting member 13 is connected to a toggle member 14, which can be connected to the limiting member 13 in the form of a pin, screw, rod-shaped workpiece, etc. The rod of the toggle member 14 passes through the sliding track 111. It can be understood that the width of the sliding track 111 is slightly larger than the rod of the toggle member 14. When the limiting member 13 is moved, the toggle member 14 plays a guiding role, so that the limiting member 13 moves linearly along the sliding track 111, preventing the limiting member 13 from deviating during movement, which would prevent the limiting member 13 from being fully in place and resulting in an inaccurate opening angle. Of course, the actuating element 14 and the limiting element 13 can also adopt an integral molding structure to enhance the overall rigidity of the components. It should be noted that the limiting element 13 and the actuating element 14 can be made of materials with a certain hardness, such as plastic or metal. This embodiment is not limited to this, and all of the above are within the protection scope of this utility model.

[0027] See Figures 1 to 11As shown, further, in one embodiment of this utility model, the actuating member 14 is at least partially exposed above the sliding track 111, and the portion of the actuating member 14 exposed above the sliding track 111 forms an actuating portion 141. It should be noted that in this embodiment, one end of the actuating member 14 is the actuating portion 141, which passes through the sliding track 111 and is exposed to the outside. Thus, the user can control the movement of the limiting member 13 by manipulating the exposed actuating portion 141, making it convenient for the user. Further, see... Figure 4 Since the sliding track 111 has a certain depth, the top surface of the actuating part 141 is flush with the outer surface of the drive arm 11. This can prevent the actuating part 141 from protruding from the drive arm 11, which would otherwise cause scratches to the user or interference with external components during use.

[0028] See Figures 1 to 11 As shown, further, in one embodiment of this utility model, the actuating part 141 is formed with a locking head 1411, which is spaced apart from the limiting member 13 to form a limiting groove 15. The actuating member 14 is movably locked into the sliding track 111 through the limiting groove 15. It should be noted that in this embodiment, the locking heads 1411 extend outward from both opposite sides of the actuating part 141, see [reference]. Figure 4 The end face of the locking head 1411 and the limiting member 13 forms a U-shaped limiting groove 15. It can be understood that the width of the limiting groove 15 is slightly larger than the wall thickness of the drive arm 11, i.e., the thickness of the sliding track 111. As can be seen from the cross-section, the limiting groove 15 clamps the inner wall of the sliding track 111, thus limiting and constraining the movement of the actuating member 14 as it moves along the sliding track 111, making the movement more stable. Furthermore, the inner sidewalls of the sliding track 111 are all guide slopes. Correspondingly, the side of the locking head 1411 facing the sliding track 111 is also a slope. The locking head 1411 rests on the inner sidewall of the sliding track 111. Through the interaction of the slopes, the contact area between the two is increased, improving the positioning accuracy and making the sliding of the actuating member 14 more stable.

[0029] See Figures 1 to 11 As shown, this embodiment provides a hinge 100, including: a hinge cup 20, a hinge body 30, and the aforementioned adjustable hinge structure 10. The hinge cup 20 is rotatably connected to one end of the drive arm 11 and one end of the linkage arm 12, respectively. The hinge body 30 is rotatably connected to the other end of the drive arm 11 and the other end of the linkage arm 12, respectively. The hinge cup 20 is opened to different angles relative to the hinge body 30 by the combined action of the drive arm 11 and the linkage arm 12.

[0030] It should be noted that in this embodiment, the hinge cup 20 is the first fixing member, and the hinge body 30 is the second fixing member. When applied to a cabinet, the hinge cup 20 is used to install on the door panel, and the hinge body 30 is used to install on the cabinet body. Of course, the adjustable hinge structure 10 of this utility model can also be applied to flip-up drawers, flip-up beds, boxes, and other products. This embodiment is not limited to this, and all of the above are within the protection scope of this utility model. Specifically, one end of the drive arm 11 and one end of the linkage arm 12 are mounted on the hinge cup 20 through a U-shaped connecting rod 16. The other end of the drive arm 11 is rotatably connected to the hinge body 30 through a motion shaft (A), and the other end of the linkage arm 12 is rotatably connected to the hinge body 30 through a motion shaft (B). For details, see [link to relevant documentation]. Figure 7 When the limiting member 13 moves to the first position, the hinge cup 20 can open to the first angle relative to the hinge body 30; see also Figure 8 When the limiting member 13 moves to the second position, the hinge cup 20 can open to the second angle relative to the hinge body 30. The first angle in this embodiment is 105° and the second angle is 85°. The working principle of the hinge 100 in this embodiment is the same as that of the aforementioned adjustable hinge structure 10, and will not be repeated here.

[0031] Furthermore, the hinge 100 is also provided with a torsion spring 40, which is sleeved on the motion shaft (A). The two torsion arms of the torsion spring 40 press against the drive arm 11 and the hinge body 30 respectively. When the hinge cup 20 opens from the closed state relative to the hinge body 30, the torsion spring 40 is compressed and deformed. When the hinge cup 20 opens to a small angle, the external force is removed, and the torsion spring 40 automatically resets, driving the hinge cup 20 back to the closed state, thus achieving automatic closing at a small angle. When the hinge cup 20 opens to a large angle, the external force is removed, and the torsion spring 40 resets and releases the elastic force, so that it automatically opens to the maximum opening angle at a large angle. As an example, the above-mentioned large angle is the angle between the hinge cup 20 and the hinge body 30, which is 52° to 105°, and the small angle is the angle between the hinge cup 20 and the hinge body 30, which is 10° to 45°. It is understood that the angles of automatic closing and automatic opening are determined by the included angle (preload angle and reset angle) between the two torsion arms of the torsion spring 40 and the installation position of the torsion spring 40. Therefore, the above-mentioned large and small angles can be adjusted according to actual use to meet different usage scenarios. This embodiment is not limited to this, and all of the above are within the protection scope of this utility model. Furthermore, an adjustable hinge seat 50 is also installed on the hinge body 30. The hinge body 30 and the hinge seat 50 are provided with multiple mounting slots 51. The multiple mounting slots 51 include slots extending longitudinally and extending laterally. By setting multiple mounting slots 51, the position of the hinge 100 installed on the cabinet through the hinge seat 50 can be adjusted, improving the applicability of the hinge 100. In this embodiment, during the opening of the hinge 100 relative to the hinge body 30, the drive arm 11 and the linkage arm 12 connected to the hinge cup 20 will approach each other. Therefore, when a large opening angle is required, the limiting member 13 is moved to avoid the linkage arm 12, and the linkage arm 12 continuously approaches the drive arm 11 until the hinge 100 is fully opened, that is, opened to the first angle. When a small opening angle is required, the limiting member 13 is moved to block the linkage arm 12 from approaching the drive arm 11, so the hinge 100 cannot continue to open and stays at the second angle. This allows for flexible adjustment of the opening angle of the hinge 100 according to the actual installation environment.

[0032] See Figures 1 to 11As shown, in one embodiment of this utility model, a damper 60 is included. The damper 60 is disposed on the hinge 30, and the movable end of the damper 60 is connected to the linkage arm 12 via a transmission connection. It should be noted that the damper 60 in this embodiment can be a buffer with a self-resetting function or a shock absorber without a self-resetting function. It can be understood that when the damper 60 has a self-resetting function, the linkage arm 12 and the movable end of the damper 60 can be connected by contact, that is, there is no direct fixed mechanical connection between the two. The linkage arm 12 pushes the movable end of the damper 60 to retract it. When the pushing force is removed, the damper 60 resets and extends by itself. The reset element inside the damper 60 can be a spring, an elastic body, etc. When the damper 60 does not have a self-resetting function, the extension of the movable end of the damper 60 requires the linkage arm 12 to drive it. Therefore, the linkage arm 12 and the movable end of the damper 60 are directly or indirectly mechanically connected. The linkage arm 12 pushes the movable end of the damper 60 to retract it, and pulls the movable end of the damper 60 to extend and reset it. This embodiment is not limited to this, and all of the above are within the protection scope of this utility model. In this embodiment, by setting the damper 60, the hinge 100 generates a damping force by compressing the damper 60 when opening or closing, thereby buffering the hinge 100 and preventing the door panel from opening or closing rapidly, which could easily damage the hinge 100 or even cause injury.

[0033] See Figures 1 to 11As shown, in one embodiment of this utility model, a mounting base 70 and a pusher 80 are further included. The mounting base 70 has a mounting cavity 71, and the pusher 80 is movably disposed at the opening end of the mounting cavity 71. One end of the pusher 80 is connected to the linkage arm 12 for transmission. A damper 60 is disposed in the mounting cavity 71, and the movable end of the damper 60 can be compressed by the pusher 80. It should be noted that the mounting base 70 in this embodiment has a fixing groove 72, and the linkage arm 12 is rotatably disposed in the fixing groove 72. The motion shaft (B) passes through the hinge body 30, the mounting base 70, and the linkage arm 12 in sequence to connect the three. Furthermore, the mounting base 70 is also fixed in the hinge body 30 by a motion shaft (C). The motion shaft (C) and the motion shaft (B) are spaced apart to form two fixed points to prevent the mounting base 70 from shifting within the hinge body 30. It should be noted that the mounting base 70 in this embodiment has a mounting cavity 71 that matches the shape of the damper 60. The damper 60 is installed in the mounting cavity 71, and its movable end extends out of the opening end of the mounting cavity 71. A channel 73 penetrating the mounting base 70 is also provided below the mounting cavity 71. At least part of the pusher 80 is movably inserted through the channel 73 and forms a space with the mounting cavity 71. It can be understood that the damper 60 is located in this space. The pusher 80 moves closer to or away from the mounting cavity 71 along the channel 73 to compress or release the movable end of the damper 60. In this way, it can be ensured that the pusher 80 moves in a straight line along the channel 73, and that the damper 60 can be pushed by a positive force, avoiding damage to the movable end of the damper 60 due to deviation of the movement trajectory of the pusher 80. It should be noted that the pusher 80 is connected to the linkage arm 12 at one end of the channel 73. As an example, when the hinge cup 20 is closed relative to the hinge body 30 in this embodiment, the linkage arm 12 rotates counterclockwise around the motion axis (B), and the linkage arm 12 drives the pusher 80 to move toward the mounting cavity 71, thereby compressing the movable end of the damper 60, so that the hinge 100 closes slowly; when the hinge cup 20 is open relative to the hinge body 30, the linkage arm 12 rotates clockwise around the motion axis (B), and the linkage arm 12 drives the pusher 80 to move away from the mounting cavity 71. When the mounting cavity 71 moves in a certain direction, the pusher 80 is driven by the linkage arm 12 and does not need to rely on the rebound force of the internal reset member of the damper 60 to return to its original position, thereby reducing the wear of the reset member and increasing the service life of the damper 60. Of course, in another embodiment, the pusher 80 can compress the damper 60 when opening and release the damper 60 when closing, depending on the installation direction of the damper 60 and the pusher 80, to meet different needs. This embodiment is not limited to this, and all of the above are within the protection scope of this utility model. Furthermore, the mounting base 70 is also provided with a slot 74. One end of the torsion spring 40 is restricted in the slot 74, and the other end is pressed against the inner wall of the drive arm 11. In this way, the slot 74 provides a fixed point so that the torsion spring 40 will not wobble during the opening and closing process of the hinge 100, and the opening and closing process of the hinge 100 is more stable.

[0034] See Figures 1 to 11 As shown, in one embodiment of this utility model, the pusher 80 has a groove 81 at one end, and the linkage arm 12 has a protrusion 122 at one end of the hinge 30. The protrusion 122 is engaged in the groove 81 so that the linkage arm 12 drives the pusher 80 to move. It should be noted that in this embodiment, the linkage arm 12 drives the pusher 80 to move by setting the protrusion 122 and the groove 81 to engage with each other. The protrusion 122 and the groove 81 are in rigid contact, and the movement and force of the linkage arm 12 can be transmitted to the pusher 80 without delay, so that the transmission efficiency between the two is high and the action response is fast. At the same time, the structure is simple, and it is only necessary to align the protrusion 122 and the groove 81 and engage them, which is convenient for assembly and maintenance.

[0035] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
