All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0049] Example 1

[0050] See Figures 1-5 This embodiment discloses a swing-type locking mechanism, including a first pull rod 1, a second pull rod 2, a base 3, and a sliding swing assembly. The base 3 is fixedly connected to the bottom of the window sash, and the two ends of the second pull rod 2 are rotatably connected to the first pull rod 1 and the base 3, respectively.

[0051] The sliding swing assembly includes a slider 4 and a swing member 5. The base 3 has a groove 301 and a guide structure. The groove 301 extends along its length, and the guide structure is located in front of the groove 301 along the window opening direction. In this embodiment, the window opening direction refers to the direction in which the slider 4 moves within the groove 301 when the window sash is opened. One end of the swing member 5 is slidably disposed in the groove 301. One end of the swing member 5 is rotatably connected to the slider 4, and the other end of the swing member 5 is adapted to the guide structure. The guide structure guides the swing member 5 to swing while sliding with the slider 4. The guide structure has a locking position 3031 for limiting the movement of the swing member 5 in the window closing direction. In this embodiment, the window closing direction refers to the direction in which the slider 4 moves within the groove 301 when the window sash is closed. In this embodiment, one end of the first pull rod 1 is rotatably connected to the slider 4, and the other end is movably connected to the window frame, specifically to the connecting rod of the hinge assembly.

[0052] In this embodiment, the slider 4 in the sliding swing assembly can effectively connect with both the first pull rod 1 and the swing member 5, enabling the first pull rod 1 to better drive the swing member 5 to move, which is beneficial to improving the stability and reliability of the swing member 5 on the base 3.

[0053] Furthermore, in this embodiment, the base 3 is provided with a hollow groove 302, which penetrates the bottom of the base 3 and is located at the corresponding position of the sliding groove 301. The first pull rod 1 is located at the bottom of the base 3 and is rotatably connected to the slider 4 after passing through the hollow groove 302 via a connector 6. In this embodiment, the connector 6 is a first rivet, and the first rivet and the first pull rod 1 are rotatably connected by a riveting process. In addition, the hollow groove 302 is provided on the base 3 to facilitate the assembly of the first pull rod 1 and the slider 4. The slider 4 and the swinging member 5 are also rotatably connected by a riveting process in this embodiment, specifically using a second rivet.

[0054] Furthermore, in this embodiment, the slider 4 has a guide block 401 on its surface facing the hollowed-out groove 302, and the guide block 401 is embedded in the hollowed-out groove 302. This allows the guide block 401 and the hollowed-out groove 302 to form a mutually guiding cooperation, which helps to improve the sliding accuracy and reliability of the slider 4.

[0055] In this embodiment, the end of the swing member 5 that is adapted to the guide structure is provided with a protruding post 501, which protrudes towards the bottom side of the base 3. The protruding post 501 facilitates cooperation with the guide structure, allowing the swing member 5 to swing more effectively under the guidance of the guide structure. Furthermore, providing a protruding post 501 at the end of the swing member 5 allows for more diverse design options for the guide structure, making the swing member 5 more adaptable. For example, the guide structure can be a groove-shaped structure, i.e., a groove with a designated path guiding effect is provided on the base 3. The protruding post 501 of the swing member 5 is embedded in the groove, and the groove guides the swing member 5 to the locking position 3031, thus achieving the suspended open state of the window sash. Alternatively, a through groove of the window closing base 3 can be directly provided at the bottom of the base 3. The through groove has a designated path guiding effect, and the protruding post 501 of the swing member 5 is inserted into the through groove, using the through groove to guide the swing member 5.

[0056] The guide structure in this embodiment includes several guide sidewalls, each of which forms a recessed guide area on the base 3. A first boss 303 is provided in the guide area, and a guide passage is formed between each guide sidewall and the sidewall of the first boss 303 to restrict the swinging member 5 from sliding and swinging in a one-way path.

[0057] The base 3 is provided with a second boss 304, a third boss 305, and a fourth boss 306. The second boss 304 and the third boss 305 are located on the side of the first boss 303 facing the slider 4, and the fourth boss 306 is located on the side of the first boss 303 facing away from the slider 4. The sidewalls of the second boss 304, the third boss 305, and the fourth boss 306, together with the two sidewalls of the base 3, form the guide sidewalls. In this embodiment, the sidewalls of the boss structures, together with the two sidewalls of the base 3, form the guide sidewalls to guide the swinging component 5. On the one hand, these boss structures can be integrated with the base 3 as a whole, or even manufactured as a single piece, which is beneficial to improving the reliability and guiding accuracy of the guide structure, and has good resistance to damage and a long service life. On the other hand, the sidewall structure of the bosses can cooperate well with the protrusions 501 on the swinging component 5, forming a reliable guiding effect on the protrusions 501, allowing the swinging component 5 to slide and swing smoothly along the preset path.

[0058] See Figure 3 Furthermore, in this embodiment, the locking position 3031 is located on the side of the first protrusion 303 facing away from the slider 4. The locking position 3031 has an opening and is recessed towards the side closer to the slider 4. Under the guidance of the guide structure, as the swing member 5 slides in the opening direction, the protrusion 501 of the swing member 5 is guided to the locking position 3031. The locking position 3031 blocks the swing member 5 and the slider 4 from sliding in the closing direction, thereby achieving the suspension and locking of the window sash and preventing accidental closure.

[0059] Meanwhile, a first end position 3061 and a second end position 3062 are provided on the guide sidewall of the first protrusion 303 facing away from the slider 4; along the movement direction of the protrusion 501 on the swing member 5 in the guide passage, the first end position 3061 and the second end position 3062 are arranged sequentially. During the window opening process, the protrusion 501 of the swing member 5 first reaches the first end position 3061, that is, at this time the corresponding window sash is pushed open to the end, and then returns to the locking position 3031 to realize the window sash suspension; during the window closing process, the protrusion 501 of the swing member 5 moves from the locking position 3031 to the second end position 3062, that is, at this time the corresponding window sash is pushed open to the end again, and then moves back to realize the smooth closing of the window sash, such as Figures 4-5 As shown; the movement trajectory of the protrusion 4-1 of the swinging component 4 in the guide passage can also be seen in [reference needed]. Figure 3 The arrow in the image.

[0060] See Figure 6This embodiment also discloses a hinge assembly, which includes the aforementioned rocker locking mechanism, a first connecting rod 7, a second connecting rod 8, and a frame fixing plate 9; the frame fixing plate 9 is fixedly connected to the window frame. One end of the first connecting rod 7 is rotatably connected to the frame fixing plate 9, and the other end is rotatably connected to the first pull rod 1 and can slide on the first pull rod 1; one end of the second connecting rod 8 is rotatably connected to the frame fixing plate 9 and can slide on the frame fixing plate 9, and the other end is rotatably connected to the first pull rod 1; a hinge point is provided between the first connecting rod 7 and the second connecting rod 8.

[0061] Example 2

[0062] The difference between this embodiment and Embodiment 1 is that:

[0063] See Figures 7-8 In this embodiment, the swing member 5 in the swing locking mechanism is hinged to the end of the first pull rod 1. Compared with embodiment 1, the slider is omitted, the number of parts is reduced, and the structure is simpler.

[0064] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
