TECHNICAL FIELD
[0001] The utility model relates to door and window technical field, especially hinge anti -swing structure and hinge. BACKGROUND
[0002] In the door and window hardware system, the hinge as the key part connecting the door and window sash and frame plays a crucial role. It not only needs to support the weight of the door and window sash, but also needs to ensure that the sash can realize stable and diverse opening and closing actions, such as flat opening, inward tilting, etc., to meet the ventilation, lighting and safety protection needs in different scenes. However, the traditional hinge design faces a series of challenges in practical application, especially in the performance of flat opening function.
[0003] The hinge under the prior art, due to factors such as material properties, machining process precision limitations, etc., there is often a certain gap between the hole and the shaft of the hinge in the machining and manufacturing process. This gap will cause the handle to shake during the opening of the door and window sash, accompanied by abnormal noise, which seriously affects the user's experience and the overall quality of the door and window. The shaking and abnormal noise not only reduce the durability and stability of the product, but also give customers the impression of poor quality, thereby affecting the brand image and market competitiveness.
[0004] In order to solve the problem of shaking, theoretically, the zero gap between the hole and the shaft can be realized by improving the machining precision. Although this method can reduce the shaking to a certain extent, it puts forward very high requirements for the manufacturing equipment and process level, not only increases the production cost, but also is difficult to realize large-scale stable application in the actual production and assembly process, which is not conducive to the cost control and popularization and promotion of the product.
[0005] On the other hand, some anti-swing structures have appeared on the market, which aim to limit the shaking of the hinge through additional mechanical devices. However, these anti-swing 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 small sash width door and window design, this space occupation limits the further reduction of sash width, reduces the application range of the product, especially in modern architectural design where space utilization requirements are extremely high. In addition, the existing anti-swing structure often needs to be distinguished according to the left and right opening directions of the door and window, which increases the complexity of production, inventory and installation, further increasing the cost.

Compared with the anti-swing structure on the current market, the structure can be adapted to smaller fan width, has wider application range, and can also reduce the processing difficulty and cost of the hinge.
[0072] Embodiment 1
[0073] Please refer to Figures 1-3 The embodiment provides an anti-swing structure of a hinge. 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 connected by sliding. The other end of the short rocker arm 4 and the other end of the base 2 are connected by rotation. The anti-swing structure of the hinge comprises an anti-swing piece 5. The anti-swing piece 5 is a blocking column. The blocking column is arranged on the short rocker arm 4. The base 2 is provided with a first elastic piece 6 matched with the blocking column.
[0074] In the embodiment, please refer to Figure 4 and Figure 5 The first elastic piece 6 comprises a limiting part 61 and an abutting part 62 connected with the limiting part 61. The base 2 is provided with a limiting groove 21 and an abutting groove 22 communicated with the limiting groove 21. The limiting part 61 is installed in the limiting groove 21. The abutting part 62 is installed in the abutting groove 22. When the hinge 1 is closed, the abutting part 62 and the blocking column abut.
[0075] Please refer to Figure 6 When the hinge 1 is opened, the long rocker arm 3 and the short rocker arm 4 are closed with the base 2. The blocking column abuts against the first elastic piece 6 into the limiting groove 21. The first elastic piece 6 is in a compressed state, which will generate a reverse acting force on the short rocker arm 4 and the base 2, thereby offsetting the gap between the hinge hole shafts and achieving the anti-swing effect.
[0076] The first elastic piece 6 is made of a material with good elastic recovery ability, such as rubber or alloy spring material. The selection of such material can ensure that the first elastic piece 6 always maintains stable elastic performance during long-term use, effectively realizing 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 production process, but also enhances the overall structural strength of the first elastic member 6. The limiting portion 61 and the limiting groove 21 are in close fit, preventing unnecessary displacement of the first elastic member 6 during the movement of the hinge 1. The abutting portion 62 has a certain space in the abutting groove 22, which can smoothly abut against the blocking column when the hinge 1 is closed, and can quickly return to the initial position by its own elasticity when the hinge 1 is opened.
[0078] In addition, the surface of the blocking column corresponding to the abutting portion 62 of the first elastic member 6 is specially treated, such as sanding or adding a wear-resistant coating, to increase the friction and wear resistance when the two abut, thereby prolonging the service life of the hinge 1.
[0079] In this embodiment, the blocking column and the short rocker arm 4 are integrally arranged, and the blocking column and the short rocker arm 4 are integrally formed, avoiding the connection loosening problem that may occur in the traditional connection mode. During the operation of the equipment, whether it is subjected to vibration or external 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 stably perform the corresponding movement, thereby improving the reliability of the entire equipment operation.
[0080] Secondly, from the perspective of production and manufacturing, the integrated arrangement simplifies the production process. There is no need for complex assembly procedures to connect the blocking column and the short rocker arm 4 together, reducing the number of parts, which not only reduces assembly errors during production, but also effectively improves production efficiency and reduces production costs when mass production.
[0081] In some embodiments, the blocking column and the short rocker arm 4 are arranged in a split manner, which is more convenient for maintenance and replacement of parts. When the blocking column is worn or damaged due to long-term use, it can be replaced individually without the need to replace 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] Please refer to Figure 7 and Figure 8The embodiment provides a hinge anti-swing structure, the hinge 1 comprises a base 2, a long swing arm 3 and a short swing arm 4, one end of the long swing arm 3 and one end of the short swing arm 4 are rotationally connected, the other end of the long swing arm 3 and one end of the base 2 are slidingly connected, and the other end of the short swing arm 4 and the other end of the base 2 are rotationally connected. The hinge anti-swing structure comprises an anti-swing piece 5, the anti-swing piece 5 is a spin rivet shaft, one end of the long swing arm 3 and one end of the short swing arm 4 are rotationally connected through the spin rivet shaft, and the base 2 is provided with a second elastic piece 7 matched with the spin rivet shaft.
[0084] Please refer to Figure 9 and Figure 10 When the hinge 1 is flatly opened, the long swing arm 3, the short swing arm 4 and the base 2 are closed, the spin rivet shaft abuts against the second elastic piece 7, the second elastic piece 7 is in a compressed state, the second elastic piece 7 can generate a reverse force on the short swing arm 4 and the base 2, so that the gap between the hole shafts of the hinge 1 can be offset, and the anti-swing effect can be achieved.
[0085] Embodiment 3:
[0086] Please refer to Figures 11-13 The embodiment provides a hinge anti-swing structure, the hinge 1 comprises a base 2, a long swing arm 3 and a short swing arm 4, one end of the long swing arm 3 and one end of the short swing arm 4 are rotationally connected, the other end of the long swing arm 3 and one end of the base 2 are slidingly connected, and the other end of the short swing arm 4 and the other end of the base 2 are rotationally connected. The hinge anti-swing structure comprises an anti-swing piece 5, the anti-swing piece 5 is a U-shaped piece, the U-shaped piece is arranged on the short swing arm 4, a third elastic piece 8 is arranged in the U-shaped piece, and the base 2 is provided with a blocking piece 9 matched with the third elastic piece 8.
[0087] When the hinge 1 is flatly opened, the long swing arm 3, the short swing arm 4 and the base 2 are closed, the spin rivet shaft abuts against the second elastic piece 7, the second elastic piece 7 is in a compressed state, the second elastic piece 7 can generate a reverse force on the short swing arm 4 and the base 2, so that the gap between the hole shafts of the hinge 1 can be offset, and the anti-swing effect can be achieved.
[0088] The third elastic piece 8 is installed on the U-shaped piece instead of being directly fixed on the short swing arm 4, and the design helps to improve the working stability and service life of the third elastic piece 8. The U-shaped piece can serve as a buffer and transition, so that the direct impact and abrasion of the third elastic piece 8 in the working process are reduced. Meanwhile, the installation mode makes the replacement and maintenance of the third elastic piece 8 more convenient, and the maintenance cost is reduced.
[0089] Further, please refer to Figure 14 and Figure 15 The U-shaped piece is provided with an elastic mounting groove 51, the bottom of the elastic mounting groove 51 is provided with a mounting portion 511, the third elastic piece 8 is provided with a matching portion 81 for inserting the mounting portion 511, and the third elastic piece 8 is installed on the U-shaped piece.
[0090] When the third elastic member 8 is installed on the U-shaped member, the close 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 existence of the elastic mounting groove 51 provides 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] In this embodiment, the middle of the U-shaped member is provided with an elastic mounting groove 51, the bottom of the elastic mounting groove 51 is protruding to form a mounting portion 511, and the third elastic member 8 is correspondingly recessed to form a matching portion 81. Alternatively, the middle of the U-shaped member is provided with an elastic mounting groove 51, the bottom of the elastic mounting groove 51 is recessed to form a mounting portion 511, and the third elastic member 8 is correspondingly protruding to form a matching portion 81.
[0092] The mounting portion 511 and the matching portion 81 are adapted to each other, so that the U-shaped member and the third elastic member 8 can be closely combined, thereby realizing the stable installation of the third elastic member 8. At the same time, this design also facilitates 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 separated relatively easily, reducing the difficulty of operation and maintenance cost.
[0093] In this embodiment, the opening of the elastic mounting groove 51 is designed in a trumpet shape, which is conducive to guiding and positioning the object during installation. At the same time, this design can also allow the plug-in part to have a small deviation to a certain extent, improving the fault tolerance rate of installation.
[0094] In this embodiment, the two ends of the U-shaped member are protruding to form at least one protruding portion 52 (as shown in Figure 14 In this embodiment, the two ends of the U-shaped member are protruding to form at least one protruding portion 52 (as shown in Figure 16 In this embodiment, the two ends of the U-shaped member are protruding to form at least one protruding portion 52 (as shown in
[0095] The design of the protruding portion 52 and the through hole 41 simplifies the installation process. During installation, the protruding portion 52 only needs to be aligned with the through hole 41 and inserted, without the need for additional fasteners or complex installation steps, thereby improving the installation efficiency.
[0096] It should be noted that the structure of the third elastic member 8, the resisting member 9 and the U-shaped member in this embodiment can also be applied to the structures of Embodiment 1 and Embodiment 2, for example, the third elastic member 8 and the U-shaped member are arranged on the base 2, and the resisting member 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 resisting member 9 is arranged on the rotary rivet shaft 10.
[0097] Embodiment 4:
[0098] Please refer to Figures 17-20The embodiment provides a hinge anti-swing structure, the hinge anti-swing structure comprises an anti-swing piece 5, the anti-swing piece 5 is a baffle, the baffle is arranged on one of a base 2, a short swing arm 4 and a long swing arm 3, and when the hinge 1 is closed, the baffle abuts against the other of the base 2, the short swing arm 4 and the long swing arm 3.
[0099] Next, the embodiment takes the case that the baffle is arranged on the short swing arm 4 and abuts against the base 2 when the hinge 1 is closed as an example and specifically describes.
[0100] Specifically, the anti-swing piece 5 comprises: a mounting section 53 and an abutting section 54, the abutting section 54 is vertically arranged at one end of the mounting section 53, and the mounting section 53 is arranged on the short swing arm 4; when the hinge 1 is closed, the base 2 abuts against the abutting section 54.
[0101] When the hinge 1 is flatly opened, the long swing arm 3, the short swing arm 4 and the base 2 are closed, the abutting section 54 abuts against the base 2, the abutting section 54 is slightly inclined, that is, the anti-swing piece 5 is slightly deformed, so that the two ends of the anti-swing piece 5 generate pulling forces on the short swing arm 4 and the base 2 respectively, thereby being capable of offsetting the gap between the hole shafts of the hinge 1 and playing an anti-swing role.
[0102] By introducing the anti-swing piece 5, a more stable supporting relationship between the base 2 and the short swing arm 4 can be formed when the hinge 1 is closed. The abutting of the abutting section 54 of the anti-swing piece 5 and the base 2 effectively limits the swing or swing of the short swing arm 4 in the closed state, thereby enhancing the stability of the whole structure. In addition, the anti-swing piece 5 is composed of the mounting section 53 and the abutting section 54, and the structure is simple and clear, easy to process and install. This design not only reduces the manufacturing cost, but also improves the production efficiency.
[0103] Further, referring to Figure 18 and Figure 19 , the anti-swing piece 5 further comprises: a limiting section 55, the limiting section 55 is vertically arranged at the other end of the mounting section 53, the abutting section 54 and the limiting section 55 are arranged on the two sides of the mounting section 53 respectively, and the mounting section 53 is mounted on the short swing arm 4 through a riveting shaft 10.
[0104] The newly added limiting section 55 can abut against the short swing arm 4, so as to prevent the anti-swing piece 5 from moving in an unexpected direction, thereby being capable of avoiding that the anti-swing piece 5 cannot play an anti-swing role.
[0105] Specifically, referring to Figure 18 and Figure 21The limiting section 55 includes a first limiting section 551 and a second limiting section 552 connected to the first limiting section 551. The short rocker arm 4 is provided with a first limiting surface 42 and a second limiting surface 43. The first limiting section 551 abuts against the first limiting surface 42 to limit the movement of the anti-swing piece 5 in a first direction, and the second limiting section 552 abuts against the second limiting surface 43 to limit the movement of the anti-swing piece 5 in a second direction. The first direction and the second direction are arranged in a cross manner.
[0106] Through the abutment of the first limiting section 551 and the first limiting surface 42, and the abutment of the second limiting section 552 and the second limiting surface 43, the anti-swing piece 5 is limited in both directions. This design effectively limits the movement of the anti-swing piece 5 in two cross directions, thereby improving its stability and safety.
[0107] Embodiment 5:
[0108] Please refer to Figures 22-25 In this embodiment, the base 2, the short rocker arm 4 or the long rocker arm 3 is provided with an adjusting rack 44, and the side of the blocking piece is provided with a mounting rack 56. The adjusting rack 44 is engaged with the mounting rack 56.
[0109] By clamping the mounting rack 56 into different teeth of the adjusting rack 44, the position of the blocking piece can be adjusted, thereby improving the applicability and practicality of the blocking piece.
[0110] This embodiment takes the blocking piece arranged on the short rocker arm 4 as an example for specific description, and the short rocker arm 4 is provided with an adjusting rack 44.
[0111] Further, the short rocker arm 4 is provided with a short rocker arm adjusting part 45, and the adjusting rack 44 is arranged on one side or both sides of the short rocker arm adjusting part 45. The mounting rack 56 is correspondingly arranged on the side of the mounting section 53. When the mounting section 53 is mounted in the short rocker arm adjusting part 45, the adjusting rack 44 is engaged with the mounting rack 56.
[0112] The short rocker arm adjusting part 45 is a groove, and at least one side of the two sides of the groove is provided with the adjusting rack 44. By clamping the mounting rack 56 into different teeth of the adjusting rack 44, the position of the anti-swing piece 5 can be adjusted, thereby improving the applicability and practicality of the anti-swing piece 5. If the anti-swing piece 5 deforms and cannot play the anti-swing role, the position of the anti-swing piece 5 can also be adjusted, so that the anti-swing piece 5 can have a certain anti-swing role again, greatly improving the service life of the anti-swing piece 5. In addition, through the engagement of the racks, the mounting section 53 can be quickly and accurately mounted in the short rocker arm adjusting part 45, without the need for complex alignment or fixing process. This greatly improves the convenience and efficiency of installation. Similarly, due to the engagement design of the racks, the mounting section 53 can also be easily detached from the short rocker arm adjusting part 45, which is convenient for maintenance and replacement.
[0113] In this embodiment, the anti-swing piece 5 is fixed on the short swing arm 4 by a screw 11 (as shown in the figure), so the anti-swing piece 5 is provided with a long strip-shaped screw hole 57 (as shown in the figure) along the position adjustment direction of the anti-swing piece 5. When the position of the anti-swing piece 5 needs to be adjusted, just loosen the screw 11, then lift the anti-swing piece 5, move it to the appropriate position, press it, and then tighten the screw 11 to complete the position adjustment of the anti-swing piece 5. Figure 22 Figure 25 The long strip-shaped screw hole 57 provides a larger adjustment range, so that the anti-swing piece 5 can move freely within a certain range. In addition, the anti-swing piece 5 is firmly fixed on the short swing arm 4 by the screw 11, ensuring stability and safety during use.

[0116] Figures 26-28 By clamping the mounting rack 56 into different teeth of the adjustment rack 44, the position of the baffle can be adjusted, thereby improving the applicability and practicality of the baffle.
[0117] This embodiment takes the baffle arranged on the base 2 as an example to illustrate the specific description.
[0118] Further, the base 2 is provided with a base adjustment part 23, and the adjustment rack 44 is arranged on one side or both sides of the base adjustment part 23, and the mounting rack 56 is correspondingly arranged on the side of the mounting section 53. When the mounting section 53 is mounted in the base adjustment part 23, the adjustment rack 44 is engaged with the mounting rack 56.
[0119] The structure and effect of the anti-swing piece 5 of this embodiment are the same as those of the anti-swing piece 5 of embodiment 5, both of which have the ability to adjust the position, and therefore will not be described in more detail.
[0120] Embodiment 7:
[0121] Please refer to In this embodiment, the baffle is installed on the base 2, the short swing arm 4 or the long swing arm 3 by the eccentric shaft 12.
[0122] Figures 29-31
[0123] Specifically, the eccentric shaft 12 comprises an eccentric segment 121 and a connecting segment 122 connected with the eccentric segment 121, the eccentric segment 121 is arranged away from the center of the connecting segment 122, and the baffle is provided with an adjusting groove 531, when the eccentric segment 121 passes through the adjusting groove 531 and is connected with one of the base 2, the short rocker arm 4 and the long rocker arm 3, the connecting segment 122 is located in the adjusting groove 531.
[0124] When the eccentric shaft 12 is rotated, the connecting segment 122 rotates around the eccentric segment 121, the rotation of the connecting segment 122 abuts against the adjusting groove 531 and exerts force on the adjusting groove 531, thereby driving the baffle to move, so that the position adjustment of the baffle can be realized.
[0125] Next, the embodiment takes the baffle installed on the base through the eccentric shaft 12 as an example for specific description.
[0126] In the embodiment, the mounting segment 53 is installed on the base 2 through the eccentric shaft 12, the eccentric shaft 12 comprises an eccentric segment 121 and a connecting segment 122 connected with the eccentric segment 121, the eccentric segment 121 is arranged away from the center of the connecting segment 122, and the mounting segment 53 is provided with an adjusting groove 531, when the eccentric segment 121 passes through the adjusting groove 531 and is connected with the base 2, the connecting segment 122 is located in the adjusting groove 531.
[0127] When the position of the anti-swing piece 5 needs to be adjusted, the eccentric shaft 12 is rotated, the connecting segment 122 rotates around the eccentric segment 121, and the rotation of the connecting segment 122 abuts against the inner wall of the adjusting groove 531 and drives the anti-swing piece 5 to move.
[0128] Further, the eccentric shaft 12 further comprises a covering segment 123, the eccentric segment 121 and the covering segment 123 are respectively arranged at two ends of the connecting segment 122, and the diameter of the covering segment 123 is greater than the width of the adjusting groove 531. The diameter of the covering segment 123 is greater than the width of the adjusting groove 531, which means that when the eccentric shaft 12 is installed and passes through the adjusting groove 531, the covering segment 123 forms a physical block on one side of the adjusting groove 531. This design effectively prevents the anti-swing piece 5 from being separated from the base 2, and greatly enhances the stability of the entire mounting structure.
[0129] Embodiment 8:
[0130] In the embodiment, please refer to Figures 32-34 , the anti-swing piece 5 comprises a mounting shaft 58 and a fourth elastic piece 59, the fourth elastic piece 59 is installed at one end of the mounting shaft 58, the other end of the mounting shaft 58 is installed on one of the base 2, the short rocker arm 4 and the long rocker arm 3, and the other one of the base 2, the short rocker arm 4 and the long rocker arm 3 is provided with an arc-shaped structure 46 matched with the fourth elastic piece 59.
[0131] When the hinge is closed, the fourth elastic member 59 will abut against the arc-shaped structure 46, thereby being able to offset the gap between the hole shafts of the hinge 1, achieving the effect of preventing swing, thereby improving the user experience and improving the efficiency of production and assembly.
[0132] Next, the embodiment will be described in detail taking the case that the other end of the mounting shaft 58 is mounted on the long rocker arm 3 and the arc-shaped structure 46 is arranged on the short rocker arm 4.
[0133] Specifically, the swing-preventing 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, and the other end of the mounting shaft 58 is mounted on the long rocker arm 3, and the arc-shaped structure 46 that cooperates with the fourth elastic member 59 is arranged on the short rocker arm 4.
[0134] When the hinge is closed, the fourth elastic member 59 will abut against the arc-shaped structure 46, thereby being able to offset the gap between the hole shafts of the hinge 1, achieving the effect of preventing swing, thereby improving the user experience and improving the efficiency of production and assembly. At the same time, the arc-shaped structure 46 can achieve closer fitting with the fourth elastic member 59, and this design improves the fitting precision between the two. The arc-shaped structure 46 can also better guide the deformation of the fourth elastic member 59, ensuring that it works within the predetermined range, thereby improving the reliability and durability of the swing-preventing member 5.
[0135] Further, the arc-shaped structure 46 is arranged on both sides of the end of the short rocker arm 4 that is connected to the base 2.
[0136] Since the arc-shaped structure 46 is arranged 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, it can ensure good contact and adaptation of the arc-shaped structure 46 with the base 2. This design eliminates the limitation of the installation direction and improves the fault tolerance of the installation.
[0137] The embodiment also provides a hinge 1, which includes the hinge swing-preventing structure of the above-described embodiment.
