Description

Technical Field

[0001] The present invention relates to the technical field of doors and windows, and in particular to a hinge anti-sway structure and a hinge. Background Art

[0002] In the door and window hardware system, hinges, as key components connecting door and window sashes and frames, play a vital role. They not only need to support the weight of the door and window sashes, but also need to ensure that the sashes can achieve smooth and diverse opening and closing actions, such as casement and tilting, to meet the ventilation, lighting and safety protection requirements in different scenarios. However, traditional hinge designs face a series of challenges in practical applications, especially in the casement function.

[0003] In the manufacturing process of hinges under existing technology, there is often a certain gap between the hole and the shaft of the hinge due to factors such as material characteristics and processing precision limitations. This gap will cause the handle to shake when the door or window sash is opened, accompanied by abnormal noise, which seriously affects the user experience and the overall quality of the door or window. Shaking and abnormal noise not only reduce the durability and stability of the product, but may also leave customers with an impression of poor quality, thereby affecting the brand image and market competitiveness.

[0004] In theory, in order to solve the shaking problem, the machining accuracy can be improved to achieve zero clearance between the hole and the shaft. Although this approach can reduce shaking to a certain extent, it places extremely high demands on manufacturing equipment and process level, which not only increases production costs, but also makes it difficult to achieve large-scale stable application in the actual production and assembly process, which is not conducive to product cost control and popularization.

[0005] On the other hand, some anti-sway structures have appeared on the market, which are designed to limit the swing of hinges through additional mechanical devices. However, these anti-sway structures are usually designed to be installed on the bottom plate or base of the hinge, which undoubtedly increases the space occupied by the hinge in the length direction. For the design of doors and windows with small sash widths, this space occupation limits the further reduction of the sash width and reduces the scope of application of the product, which is particularly inconvenient in modern architectural designs that have extremely high requirements for space utilization. In addition, existing anti-sway structures often need to be distinguished according to the left and right opening directions of doors and windows, which increases the complexity of production, inventory and installation, and further increases costs. Summary of the invention

[0006] The purpose of the present invention is to provide a hinge anti-sway structure and a hinge, aiming to solve the problems of poor adaptability and high cost of the existing hinge anti-sway structure.

[0011] Furthermore, the anti-swaying member is a baffle, which is arranged on one of the base, the short rocker arm and the long rocker arm. When the hinge is closed, the baffle abuts against the other one of the base, the short rocker arm and the long rocker arm.

[0012] Furthermore, an adjusting rack is provided on the base, the short rocker arm or the long rocker arm, and a mounting rack is provided on the side of the baffle, and the adjusting rack is meshed with the mounting rack.

[0013] Furthermore, the baffle is installed on the base, the short rocker arm or the long rocker arm through an eccentric shaft.

[0014] Furthermore, the eccentric shaft includes an eccentric section and a connecting section connected to the eccentric section, the eccentric section is arranged deviating from the center of the connecting section, and an adjustment groove is arranged on the baffle. When the eccentric section passes through the adjustment groove and is connected to one of the base, the short rocker arm and the long rocker arm, the connecting section is located in the adjustment groove.

[0015] Furthermore, the anti-sway component includes a mounting shaft and a fourth elastic component, the fourth elastic component is mounted on one end of the mounting shaft, and the other end of the mounting shaft is mounted on one of the base, the short rocker arm and the long rocker arm, and the other of the base, the short rocker arm and the long rocker arm is provided with an arc structure that cooperates with the fourth elastic component.

[0016] An embodiment of the present invention further provides a hinge, comprising: the above-mentioned hinge anti-sway structure.

[0017] The present invention discloses a hinge anti-sway structure and a hinge, wherein the hinge comprises: a base, a long rocker arm and a short rocker arm, wherein one end of the long rocker arm is rotatably connected to one end of the short rocker arm, the other end of the long rocker arm is slidably connected to one end of the base, and the other end of the short rocker arm is rotatably connected to the other end of the base.

[0066] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0067] It should be understood that when used in this specification and the appended claims, the terms "include" and "comprises" indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0068] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0069] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0070] See also Figure 1-3 The present embodiment provides a hinge anti-sway structure, the hinge 1 comprises: a base 2, a long rocker arm 3 and a short rocker arm 4, one end of the long rocker arm 3 is rotatably connected to one end of the short rocker arm 4, the other end of the long rocker arm 3 is slidably connected to one end of the base 2, the other end of the short rocker arm 4 is rotatably connected to the other end of the base 2, the hinge anti-sway structure comprises an anti-sway component 5, the anti-sway component 5 is arranged on one of the short rocker arm 4, the base 2 and the long rocker arm 3, when the hinge 1 is closed, the anti-sway component 5 abuts against the other of the short rocker arm 4, the base 2 and the long rocker arm 3.

[0071] This embodiment can reduce the shaking and abnormal noise when the door is opened by adding an anti-sway structure to the hinge. Specifically, when the long rocker arm 3, the short rocker arm 4 and the base 2 are closed, the anti-sway structure will generate a force between the short rocker arm 4, the base 2 and the long rocker arm 3, which can offset the gap between the hinge hole axis and play an anti-sway effect, thereby improving the user experience and the efficiency of production and assembly. Compared with the anti-sway structure currently on the market, this structure can adapt to smaller door widths, has a wider range of applications, and can also reduce the processing difficulty and cost of the hinge.

[0072] Embodiment 1:

[0073] See also Figure 1-3 The present embodiment provides a hinge anti-sway structure, wherein the hinge 1 comprises: a base 2, a long rocker arm 3 and a short rocker arm 4, wherein one end of the long rocker arm 3 is connected to one end of the short rocker arm 4 by rotation, the other end of the long rocker arm 3 is connected to one end of the base 2 by sliding, and the other end of the short rocker arm 4 is connected to the other end of the base 2 by rotation. The hinge anti-sway structure comprises an anti-sway component 5, which is a stop column, and the stop column is arranged on the short rocker arm 4, and a first elastic component 6 cooperating with the stop column is arranged on the base 2.

[0074] In this embodiment, please refer to Figure 4 and Figure 5 The first elastic member 6 includes: a limiting portion 61 and an abutting portion 62 connected to the limiting portion 61. A limiting groove 21 and an abutting groove 22 connected to the limiting groove 21 are provided on the base 2. The limiting portion 61 is installed in the limiting groove 21, and the abutting portion 62 is installed in the abutting groove 22. When the hinge 1 is closed, the abutting portion 62 abuts against the blocking column.

[0075] See also Figure 6 When the hinge 1 is opened horizontally, the long rocker arm 3, the short rocker arm 4 and the base 2 are closed, and the blocking column presses against the first elastic member 6 to enter the limiting groove 21. The first elastic member 6 is in a compressed state, which will produce a reverse force on the short rocker arm 4 and the base 2, thereby offsetting the gap between the hole axis of the hinge 1 and playing an anti-swaying role.

[0076] The first elastic member 6 is made of a material with good elastic recovery ability, such as rubber or alloy spring material. The selection of such a material can ensure that the first elastic member 6 always maintains stable elastic performance during long-term use, and effectively realizes its function between the base 2 and the short rocker arm 4.

[0077] The limiting portion 61 and the abutting portion 62 of the first elastic member 6 are integrally formed, which not only simplifies the manufacturing process, but also enhances the overall structural strength of the first elastic member 6. The limiting portion 61 and the limiting groove 21 are tightly matched to prevent unnecessary displacement of the first elastic member 6 during the movement of the hinge 1. The abutting portion 62 has a certain movable space in the abutting groove 22. When the hinge 1 is closed, the abutting portion 62 can smoothly abut against the abutting column, and when the hinge 1 is opened, it can quickly return to the initial position by relying on its own elasticity.

[0078] In addition, the surfaces of the abutment column and the abutment portion 62 of the first elastic member 6 are specially treated, such as frosting or adding a wear-resistant coating, to increase the friction and wear resistance when the two abut, thereby extending the service life of the hinge 1.

[0079] In this embodiment, the blocking column and the short rocker arm 4 are integrated, and the blocking column and the short rocker arm 4 are integrally formed, which avoids the problem of loose connection that may occur in the traditional connection method. During the operation of the equipment, whether it is subjected to vibration or external force impact, the integrated structure can maintain its integrity, ensuring that the blocking column always accurately performs its function, and the short rocker arm 4 can also stably perform corresponding movements, thereby improving the reliability of the operation of the entire equipment.

[0080] Secondly, from the perspective of manufacturing, the integrated setting simplifies the production process. No complicated assembly process is required to connect the retaining column and the short rocker arm 4 together, which reduces the number of parts, which not only reduces the assembly error in the production process, but also effectively improves production efficiency and reduces production costs in large-scale production.

[0081] In some embodiments, the retaining column and the short rocker arm 4 are separated, which is more convenient for repair and replacement of parts. When the retaining column is worn or damaged due to long-term use, it can be replaced alone without replacing the entire short rocker arm 4 assembly, which not only saves maintenance costs, but also shortens the maintenance time of the equipment and improves the overall operation efficiency of the equipment.

[0082] Embodiment 2:

[0083] See also Figure 7 and Figure 8The present embodiment provides a hinge anti-sway structure, the hinge 1 comprises: a base 2, a long rocker arm 3 and a short rocker arm 4, one end of the long rocker arm 3 and one end of the short rocker arm 4 are connected by rotation, the other end of the long rocker arm 3 and one end of the base 2 are slidably connected, and the other end of the short rocker arm 4 is connected by rotation with the other end of the base 2. The hinge anti-sway structure comprises an anti-sway component 5, the anti-sway component 5 is a rivet shaft, one end of the long rocker arm 3 and one end of the short rocker arm 4 are connected by rotation through the rivet shaft, and a second elastic component 7 cooperating with the rivet shaft is provided on the base 2.

[0084] See also Fig. 9 and Fig.10 When the hinge 1 is opened horizontally, the long rocker arm 3, the short rocker arm 4 and the base 2 are closed, and the rivet shaft is against the second elastic member 7. The second elastic member 7 is in a compressed state, which will produce a reverse force on the short rocker arm 4 and the base 2, thereby offsetting the gap between the hole axis of the hinge 1 and playing an anti-swaying role.

[0085] Embodiment 3:

[0086] See also Figure 11-13 The present embodiment provides a hinge anti-sway structure, wherein the hinge 1 comprises: a base 2, a long rocker arm 3 and a short rocker arm 4, wherein one end of the long rocker arm 3 is rotatably connected to one end of the short rocker arm 4, the other end of the long rocker arm 3 is slidably connected to one end of the base 2, and the other end of the short rocker arm 4 is rotatably connected to the other end of the base 2. The hinge anti-sway structure comprises an anti-sway component 5, which is a U-shaped component, which is arranged on the short rocker arm 4, and a third elastic component 8 is arranged inside the U-shaped component, and a blocking component 9 cooperating with the third elastic component 8 is arranged on the base 2.

[0087] When the hinge 1 is opened horizontally, the long rocker arm 3, the short rocker arm 4 and the base 2 are closed, and the stopper 9 abuts against the third elastic member 8. The third elastic member 8 is in a compressed state, which will generate a reverse force on the short rocker arm 4 and the base 2, thereby offsetting the gap between the hole axis of the hinge 1 and playing an anti-swaying role.

[0088] The third elastic member 8 is mounted on the U-shaped member, rather than being directly fixed on the short rocker arm 4. This design helps to improve the working stability and life of the third elastic member 8. The U-shaped member can act as a buffer and transition to reduce the direct impact and wear of the third elastic member 8 during operation. At the same time, this installation method also makes it easier to replace and maintain the third elastic member 8, reducing maintenance costs.

[0089] For further information, see Fig.14 and Fig.15 The U-shaped member is provided with an elastic mounting groove 51, a mounting portion 511 is provided at the bottom of the elastic mounting groove 51, a matching portion 81 for inserting the mounting portion 511 is provided on the third elastic member 8, and the third elastic member 8 is installed on the U-shaped member.

[0090] When the third elastic member 8 is installed on the U-shaped member, the tight combination of the mounting portion 511 and the matching portion 81 can ensure that the third elastic member 8 will not be easily displaced when subjected to external force. At the same time, the presence of the elastic mounting groove 51 provides a clear positioning for the installation of the third elastic member 8, making the installation process more convenient and efficient, and reducing errors in the installation process.

[0091] The U-shaped member is provided with an elastic mounting groove 51 in the middle, the bottom of the elastic mounting groove 51 protrudes to form a mounting portion 511, and the third elastic member 8 is correspondingly recessed to form a matching portion 81. Alternatively, the U-shaped member is provided with an elastic mounting groove 51 in the middle, the bottom of the elastic mounting groove 51 is recessed to form a mounting portion 511, and the third elastic member 8 is correspondingly protruded to form a matching portion 81.

[0092] The mounting portion 511 is matched with the matching portion 81, so that the U-shaped member and the third elastic member 8 can be tightly combined, thereby achieving a stable installation of the third elastic member 8. At the same time, this design is also convenient for installation and disassembly. When the device needs to be repaired or parts need to be replaced, the U-shaped member and the third elastic member 8 can be easily separated, reducing the difficulty of operation and maintenance costs.

[0093] In this embodiment, the opening of the elastic installation slot 51 is horn-shaped, which is conducive to guiding and positioning the object during installation. At the same time, this design can also allow a slight deviation of the plug-in to a certain extent, thereby improving the tolerance of installation.

[0094] In this embodiment, both ends of the U-shaped member are raised to form at least one raised portion 52 (eg Fig.14 As shown), at least two through holes 41 are correspondingly provided on the short rocker arm 4 (as shown Fig.16 As shown), each protrusion 52 is installed in a through hole 41,

[0095] The design of the protrusion 52 and the through hole 41 simplifies the installation process. During installation, the protrusion 52 only needs to be aligned with the through hole 41 and inserted, without the need for additional fasteners or complicated installation steps, thereby improving installation efficiency.

[0096] It should be noted that the structures of the third elastic member 8, the stopper 9 and the U-shaped member of this embodiment can also be applied to the structures of Embodiments 1 and 2. For example, the third elastic member 8 and the U-shaped member are arranged on the base 2, and the stopper 9 is arranged on the short rocker arm 4. Alternatively, the third elastic member 8 and the U-shaped member are arranged on the base 2, and the stopper 9 is arranged on the rivet shaft 10.

[0097] Embodiment 4:

[0098] See also Figure 17-20The present embodiment provides a hinge anti-sway structure, which includes an anti-sway component 5, which is a baffle, which is arranged on one of the base 2, the short rocker arm 4 and the long rocker arm 3. When the hinge 1 is closed, the baffle abuts against the other one of the base 2, the short rocker arm 4 and the long rocker arm 3.

[0099] Next, this embodiment is specifically described by taking an example in which a blocking piece is disposed on the short rocker arm 4 and when the hinge 1 is closed, the blocking piece abuts against the base 2 .

[0100] Specifically, the anti-swaying member 5 includes: a mounting section 53 and an abutting section 54 . The abutting section 54 is vertically arranged at one end of the mounting section 53 . The mounting section 53 is arranged on the short rocker arm 4 . When the hinge 1 is closed, the base 2 abuts against the abutting section 54 .

[0101] When the hinge 1 is opened horizontally, the long rocker arm 3, the short rocker arm 4 and the base 2 are closed, and the abutment section 54 will abut against the base 2. The abutment section 54 will be slightly tilted, that is, the anti-sway component 5 will be slightly deformed. In this way, the two ends of the anti-sway component 5 will respectively generate pulling force on the short rocker arm 4 and the base 2, thereby offsetting the gap between the hole axis of the hinge 1 and playing an anti-sway role.

[0102] By introducing the anti-sway member 5, when the hinge 1 is closed, a more stable supporting relationship can be formed between the base 2 and the short rocker arm 4. The abutment between the abutment section 54 of the anti-sway member 5 and the base 2 effectively limits the swing or shaking of the short rocker arm 4 in the closed state, thereby enhancing the stability of the entire structure. In addition, the anti-sway member 5 is composed of the installation section 53 and the abutment section 54, and the structure is simple and clear, and it is easy to process and install. This design not only reduces the manufacturing cost, but also improves the production efficiency.

[0103] For further information, see Fig.18 and Fig.19 The anti-swaying member 5 also includes: a limiting section 55, which is vertically arranged at the other end of the mounting section 53, and the abutting section 54 and the limiting section 55 are respectively arranged on both sides of the mounting section 53, and the mounting section 53 is installed on the short rocker arm 4 through the riveting shaft 10.

[0104] The newly added limiting section 55 can abut against the short rocker arm 4 to prevent the anti-sway member 5 from moving in an undesired direction, thereby preventing the anti-sway member 5 from failing to play an anti-sway role.

[0105] For details, please refer to Fig.18 and Fig.21The limit section 55 includes: a first limit section 551 and a second limit section 552 connected to the first limit section 551. The short rocker arm 4 is provided with a first limit surface 42 and a second limit surface 43. The first limit section 551 abuts against the first limit surface 42 to limit the anti-swaying member 5 from moving in the first direction. The second limit section 552 abuts against the second limit surface 43 to limit the anti-swaying member 5 from moving in the second direction. The first direction and the second direction are cross-arranged.

[0106] The first limiting section 551 abuts against the first limiting surface 42, and the second limiting section 552 abuts against the second limiting surface 43, thereby realizing bidirectional limiting of the anti-swaying member 5. This design effectively limits the movement of the anti-swaying member 5 in two intersecting directions, thereby improving its stability and safety.

[0107] Embodiment 5:

[0108] See also Figure 22-25 In this embodiment, an adjusting rack 44 is provided on the base 2, the short rocker arm 4 or the long rocker arm 3, and a mounting rack 56 is provided on the side of the baffle, and the adjusting rack 44 is meshed with the mounting rack 56.

[0109] By inserting the mounting rack 56 into different teeth on the adjusting rack 44 , the position of the baffle can be adjusted, thereby improving the applicability and practicality of the baffle.

[0110] This embodiment is specifically described by taking an example in which a blocking piece is arranged on the short rocker arm 4 and an adjusting rack 44 is arranged on the short rocker arm 4 .

[0111] Furthermore, a short rocker arm adjusting portion 45 is provided on the short rocker arm 4, an adjusting rack 44 is provided on one side or both sides of the short rocker arm adjusting portion 45, and an installing rack 56 is correspondingly provided on the side of the installing section 53. When the installing section 53 is installed in the short rocker arm adjusting portion 45, the adjusting rack 44 is meshed with the installing rack 56.

[0112] The short rocker arm adjustment portion 45 is provided with a groove, and at least one side of the two sides of the groove is provided with an adjustment rack 44. By inserting the mounting rack 56 into different teeth on the adjustment rack 44, the position adjustment of the anti-swaying member 5 can be achieved, thereby improving the applicability and practicality of the anti-swaying member 5. If the anti-swaying member 5 is deformed and cannot play an anti-swaying role, the position of the anti-swaying member 5 can be adjusted so that the anti-swaying member 5 can regain a certain anti-swaying role, which greatly improves the service life of the anti-swaying member 5. In addition, through the meshing of the rack, the installation section 53 can be quickly and accurately installed in the short rocker arm adjustment portion 45 without the need for complicated alignment or fixing processes. This greatly improves the convenience and efficiency of installation. Similarly, due to the meshing design of the rack, the installation section 53 can also be easily removed from the short rocker arm adjustment portion 45 for easy maintenance and replacement.

[0113] In this embodiment, the anti-swaying member 5 is connected by screws 11 (such as Fig. 22 As shown in FIG. 1 , the anti-sway member 5 is fixed to the short rocker arm 4, so a long strip of screw holes 57 (as shown in FIG. 1 ) are provided on the anti-sway member 5 along the position adjustment direction of the anti-sway member 5. Fig.25 As shown), when the position of the anti-sway member 5 needs to be adjusted, the screw 11 needs to be loosened, and then the anti-sway member 5 is lifted, and then the anti-sway member 5 is moved to a suitable position and then the anti-sway member 5 is pressed, and then the screw 11 is tightened to complete the position adjustment of the anti-sway member 5.

[0114] The design of the long strip screw hole 57 provides a larger adjustment range, so that the anti-sway member 5 can move freely within a certain range. In addition, by fixing with the screw 11, the anti-sway member 5 can be firmly installed on the short rocker arm 4 to ensure stability and safety during use.

[0115] Embodiment 6:

[0116] See also Figure 26-28 In this embodiment, an adjusting rack 44 is provided on the base 2, the short rocker arm 4 or the long rocker arm 3, and a mounting rack 56 is provided on the side of the baffle, and the adjusting rack 44 is meshed with the mounting rack 56.

[0117] By inserting the mounting rack 56 into different teeth on the adjusting rack 44 , the position of the baffle can be adjusted, thereby improving the applicability and practicality of the baffle.

[0118] This embodiment is specifically described by taking an example that the blocking piece is disposed on the base 2 and the adjusting rack 44 is disposed on the base 2 .

[0119] Furthermore, a base adjustment portion 23 is provided on the base 2, an adjustment rack 44 is provided on one side or both sides of the base adjustment portion 23, and an installation rack 56 is correspondingly provided on the side of the installation section 53. When the installation section 53 is installed in the base adjustment portion 23, the adjustment rack 44 is engaged with the installation rack 56.

[0120] The structure and effect of the anti-swaying member 5 of this embodiment are the same as those of the anti-swaying member 5 of embodiment 5, and both have position adjustment capabilities, which will not be elaborated on herein.

[0121] Embodiment 7:

[0122] See also Figure 29-31 In this embodiment, the baffle is installed on the base 2, the short rocker arm 4 or the long rocker arm 3 through the eccentric shaft 12.

[0123] Specifically, the eccentric shaft 12 includes an eccentric section 121 and a connecting section 122 connected to the eccentric section 121. The eccentric section 121 is set offset from the center of the connecting section 122. An adjustment groove 531 is set on the baffle. When the eccentric section 121 passes through the adjustment groove 531 and is connected to one of the base 2, the short rocker arm 4 and the long rocker arm 3, the connecting section 122 is located in the adjustment groove 531.

[0124] When the eccentric shaft 12 is rotated, the connecting section 122 rotates around the eccentric section 121 . The connecting section 122 rotates to abut against the adjusting slot 531 and exerts a force on the adjusting slot 531 , thereby driving the blocking piece to move, thereby adjusting the position of the blocking piece.

[0125] Next, this embodiment is specifically described by taking an example in which the baffle is installed on the base through the eccentric shaft 12 .

[0126] In this embodiment, the mounting section 53 is installed on the base 2 through the eccentric shaft 12. The eccentric shaft 12 includes an eccentric section 121 and a connecting section 122 connected to the eccentric section 121. The eccentric section 121 is set offset from the center of the connecting section 122. An adjustment groove 531 is set on the mounting section 53. When the eccentric section 121 passes through the adjustment groove 531 and is connected to the base 2, the connecting section 122 is located in the adjustment groove 531.

[0127] When the position of the anti-sway component 5 needs to be adjusted, the eccentric shaft 12 is rotated, and the connecting section 122 rotates around the eccentric section 121. The connecting section 122 rotates to abut against the inner wall of the adjustment groove 531 and drive the anti-sway component 5 to move.

[0128] Furthermore, the eccentric shaft 12 further includes a covering section 123. The eccentric section 121 and the covering section 123 are respectively arranged at both ends of the connecting section 122, and the diameter of the covering section 123 is greater than the width of the adjusting slot 531. The diameter of the covering section 123 is greater than the width of the adjusting slot 531, which means that when the eccentric shaft 12 is installed and passes through the adjusting slot 531, the covering section 123 will form a physical barrier on one side of the adjusting slot 531. This design effectively prevents the anti-swaying member 5 from detaching from the base 2, greatly enhancing the stability of the entire installation structure.

[0129] Embodiment 8:

[0130] In this embodiment, please refer to Figure 32-34 The anti-sway member 5 includes a mounting shaft 58 and a fourth elastic member 59. The fourth elastic member 59 is mounted on one end of the mounting shaft 58. The other end of the mounting shaft 58 is mounted on one of the base 2, the short rocker arm 4 and the long rocker arm 3. The other one of the base 2, the short rocker arm 4 and the long rocker arm 3 is provided with an arc structure 46 that cooperates with the fourth elastic member 59.

[0131] When the hinge is closed, the fourth elastic member 59 will abut against the arc structure 46, thereby offsetting the gap between the hole axis of the hinge 1, playing an anti-swaying effect, thereby improving the user experience and the efficiency of production and assembly.

[0132] Next, this embodiment is described in detail by taking the example that the other end of the mounting shaft 58 is mounted on the long rocker arm 3 and the arc structure 46 is provided on the short rocker arm 4 .

[0133] Specifically, the anti-sway component 5 includes a mounting shaft 58 and a fourth elastic component 59. The fourth elastic component 59 is mounted on one end of the mounting shaft 58. The other end of the mounting shaft 58 is mounted on the long rocker arm 3. The short rocker arm 4 is provided with an arc structure 46 that cooperates with the fourth elastic component 59.

[0134] When the hinge is closed, the fourth elastic member 59 will abut against the arc structure 46, thereby offsetting the gap between the hinge 1 hole axis, playing an anti-swaying effect, thereby improving the user experience and the efficiency of production and assembly. At the same time, the arc structure 46 can achieve a tighter fit with the fourth elastic member 59, and this design improves the matching accuracy between the two. The arc structure 46 can also better guide the deformation of the fourth elastic member 59 to ensure that it works within a predetermined range, thereby improving the reliability and durability of the anti-swaying member 5.

[0135] Furthermore, arc structures 46 are provided on both sides of one end of the short rocker arm 4 connected to the base 2 .

[0136] Since the arc structure 46 is provided on both sides of the short rocker arm 4, no matter which side of the short rocker arm 4 faces the base 2 for installation, the arc structure 46 can be ensured to be in good contact and fit with the base 2. This design eliminates the limitation of the installation direction and improves the tolerance of the installation.
