[0048] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.

[0049] As Figures 1-11The utility model provides a kind of connecting structure of window, including first connecting mechanism 1, second connecting mechanism 2, third connecting mechanism 3 and fourth connecting mechanism 4, first connecting mechanism 1 is arranged at the upper end of the first side of sash 9, and with window frame 8 rotation and sliding connection;Second connecting mechanism 2 is arranged at the lower end of the first side of sash 9, and with window frame 8 rotation and sliding connection, and only allow sash 9 move along the direction perpendicular to window frame 8 or along the direction parallel to window frame 8;Third connecting mechanism 3 is arranged at the upper end of the second side of window frame 8, and with sash 9 rotation and sliding connection;Fourth connecting mechanism 4 is arranged at the lower end of the second side of window frame 8, and with sash 9 rotation and sliding connection.

[0050] The utility model discloses a kind of connecting structure of window, including first connecting mechanism 1, second connecting mechanism 2, third connecting mechanism 3 and fourth connecting mechanism 4, first connecting mechanism 1 is arranged at the upper end of the first side of sash 9, and with window frame 8 rotation and sliding connection;Second connecting mechanism 2 is arranged at the lower end of the first side of sash 9, and with window frame 8 rotation and sliding connection, and only allow sash 9 move along the direction perpendicular to window frame 8 or along the direction parallel to window frame 8;Third connecting mechanism 3 is arranged at the upper end of the second side of window frame 8, and with sash 9 rotation and sliding connection;Fourth connecting mechanism 4 is arranged at the lower end of the second side of window frame 8, and with sash 9 rotation and sliding connection.

[0051] Further, second connecting mechanism 2 includes second hinged assembly, second sliding assembly 24, locking piece 25 and locking seat 26, second hinged assembly is arranged at the lower end of the first side of sash 9, the second connecting arm 21 of second hinged assembly is connected with second sliding assembly 24 rotation, and is set with the limiting slot 211 of being adapted with locking piece 25;Second sliding assembly 24 is connected with the lower groove a82 of window frame 8 sliding;Locking seat 26 is arranged on the lower groove a82 of window frame 8, and is set with the locking slot of being adapted with locking piece 25;Locking piece 25 is connected with second sliding assembly 24 rotation, for being engaged or disengaged with limiting slot 211 or locking slot under the different state of sash 9;

[0052] Specifically, when sash 9 is in the open state, the first end of locking piece 25 is engaged with the limiting slot 211, and the second end is in a free state without contacting the locking slot. This arrangement allows sash 9 to translate along the direction parallel to window frame 8, and simultaneously, due to the engagement of locking piece 25 with the limiting slot 211, effectively prevents sash 9 from accidentally moving along the direction perpendicular to window frame 8 during translation, thereby avoiding unnecessary collisions and wear and tear.

[0053] When the window sash 9 needs to be closed, the second sliding assembly 24 is moved along the lower groove a82 of the window frame 8 by manually operating the driving window sash 9, in the process of movement, the second end of the locking piece 25 enters the locking groove and is clamped with it, at the same time, the first end of the locking piece 25 is disengaged from the limiting groove 211, so that the window sash 9 can freely translate along the direction perpendicular to the window frame 8 to perform the closing action.

[0054] When the window sash 9 needs to be opened, the second sliding assembly 24 is moved along the lower groove a82 of the window frame 8 by manually operating the driving window sash 9, in the process of movement, the second end of the locking piece 25 is disengaged from the locking groove, at the same time, the first end of the locking piece 25 re-enters the limiting groove 211 and is clamped with it, the window sash 9 can no longer move along the direction perpendicular to the window frame 8. This arrangement allows the window sash 9 to perform the translational action again along the horizontal direction parallel to the window frame 8 after completely escaping from the restraint of the window frame 8, without interference with the window frame 8, avoiding unnecessary collision and wear.

[0055] In the above process, the first connecting mechanism 1, the third connecting mechanism 3 and the fourth connecting mechanism 4 move with the window sash 9, together ensuring the stability and reliability of the action of the window sash 9.

[0056] The first connecting mechanism 1 and the second connecting mechanism 2 are arranged on the first side of the window sash 9 away from the handrail. The third connecting mechanism 3 and the fourth connecting mechanism 4 are arranged on the second side of the window frame 8 close to the handrail.

[0057] As shown in Figure 9 , the upper groove a81 and the lower groove a82 of the window frame 8 and the upper groove b91 and the lower groove b92 of the window sash 9 are the standard C-shaped grooves in the prior art.

[0058] As an optional embodiment, as shown in Figure 3 , Figure 4 , the second hinge assembly further includes a second positioning arm 23 and a second rotating part 22 rotatably connected with the second connecting arm 21, the second rotating part 22 is arranged on the first side groove b93 of the window sash 9, and the second positioning arm 23 is arranged on the lower groove b92 of the window sash 9; the locking piece 25 is arranged on the side plate of the second sliding assembly 24 and connected with the second sliding assembly 24 through the spring 27.

[0059] Further, the second rotating part 22 and the second positioning arm 23 are arranged below the first side corner of the window sash 9. Specifically, the second shaft sleeve 221 of the second rotating part 22 is arranged at the lower part of the first side groove b93 of the window sash 9 and connected by bolts. The second positioning arm 23 is embedded in the first end of the lower groove b92 of the window sash 9 and connected by bolts.

[0060] The second connecting arm 21 is connected with the second rotating shaft 222 of the second rotating part 22 at one end and connected with the top plate of the second sliding assembly 24 through a rotating shaft at the other end. The limiting slot 211 is arranged at the end of the second connecting arm 21 close to the locking piece 25, and the opening direction is obliquely arranged to guide the locking piece 25 to enter the limiting slot 211 more easily and to be kept at the preset locking position, thereby increasing the stability of the locking piece 25 in the limiting slot 211.

[0061] The locking piece 25 is connected with the side plate of the second sliding assembly 24 close to the second positioning arm 23 through a rotating shaft, so that the locking piece 25 can rotate around the hinge point in the vertical direction. The first end of the locking piece 25 extends upward in the vertical direction, so that it can effectively limit the second positioning arm 23 after entering the limiting slot 211, thereby preventing the second positioning arm 23 from moving in the direction perpendicular to the window frame 8. The second end of the locking piece 25 is provided with a hook part 251 matched with the locking slot.

[0062] The opening direction of the locking slot is towards the second sliding assembly 24 and is arranged through in the direction perpendicular to the window frame 8. The upper part of the locking slot is provided with a locking protrusion 261 matched with the hook part 251, and the lower part of the locking slot is provided with a guide slope 262, so that the hook part 251 can smoothly slide into the locking slot along the guide slope 262 and be clamped with the locking protrusion 261 during the closing process of the window sash 9. Similarly, when the window sash 9 needs to be opened, the hook part 251 can also smoothly slide out of the locking slot along the guide slope 262 to be separated from the locking protrusion 261.

[0063] The spring 27 is arranged on the second sliding assembly 24 and connected with the locking piece 25 through an L-shaped connecting piece and can be stretched and contracted in the vertical direction to provide a reset force for the locking piece 25. When the second end of the locking piece 25 is clamped with the locking slot, the spring 27 is in a compressed state. When the window sash 9 needs to be opened, the second end of the locking piece 25 is released from the locking slot, at this time, the spring 27 releases the elastic potential energy stored therein to drive the locking piece 25 to rotate and reset, that is, the first end of the locking piece 25 enters the limiting slot 211.

[0064] A plurality of second pulleys 241 are arranged below the second sliding assembly 24, the second pulleys 241 are arranged at intervals along the length direction of the lower groove a82 and are in sliding cooperation with the lower groove a82 of the window frame 8. A guide protrusion can be arranged on the lower groove a82 according to the use requirement, and a guide groove matched with the guide protrusion is arranged on the second pulley 241, so that when the second pulley 241 rolls in the lower groove a82, the guide groove can tightly fit the guide protrusion, so that the window sash 9 will not deviate from the predetermined track during the translation.

[0065] The second sliding assembly 24 is provided with a mounting groove 242 on the side plate close to the locking seat 26, and the buffer part is embedded in the mounting groove 242, which is used to reduce the friction and impact between the second sliding assembly 24 and the locking seat 26 during sliding.

[0066] As shown in FIG. 1, when the sash 9 is in the closed state, the second end of the locking piece 25 is engaged with the locking groove on the window frame 8, at this time, the second connecting arm 21 is located above the second sliding assembly 24 and is substantially parallel to the second sliding assembly 24, and continuously applies downward pressure to the first end of the locking piece 25, and the spring 27 is in the compressed state. Figure 4 As shown in FIG. 2, when the sash 9 needs to be opened, the user manually operates to pull the sash 9 outward, which drives the second connecting arm 21 to rotate. With the rotation of the second connecting arm 21, the limiting groove 211 is moved to the position corresponding to the locking piece 25, at this time, the second connecting arm 21 releases the pressure on the locking piece 25, the spring 27 releases the stored elastic potential energy, and drives the locking piece 25 to rotate around the hinge point thereof, the first end of the locking piece 25 is raised and enters the limiting groove 211, and is kept in the preset locking position. At the same time, the hook part 251 of the second end of the locking piece 25 gradually descends and is separated from the locking protrusion 261 of the locking groove. Since the first end of the locking piece 25 is always engaged with the limiting groove 211, the sash 9 cannot be translated in the direction perpendicular to the window frame 8, so that the sash 9 is completely released from the window frame 8, and the user can translate the sash 9 in the direction parallel to the window frame 8 according to the use requirement.

[0067] Figure 3 As shown in FIG. 2, when the sash 9 needs to be opened, the user manually operates to pull the sash 9 outward, which drives the second connecting arm 21 to rotate. With the rotation of the second connecting arm 21, the limiting groove 211 is moved to the position corresponding to the locking piece 25, at this time, the second connecting arm 21 releases the pressure on the locking piece 25, the spring 27 releases the stored elastic potential energy, and drives the locking piece 25 to rotate around the hinge point thereof, the first end of the locking piece 25 is raised and enters the limiting groove 211, and is kept in the preset locking position. At the same time, the hook part 251 of the second end of the locking piece 25 gradually descends and is separated from the locking protrusion 261 of the locking groove. Since the first end of the locking piece 25 is always engaged with the limiting groove 211, the sash 9 cannot be translated in the direction perpendicular to the window frame 8, so that the sash 9 is completely released from the window frame 8, and the user can translate the sash 9 in the direction parallel to the window frame 8 according to the use requirement.

[0068] The process of closing the sash 9 is opposite to that of opening. The sash 9 is pushed, the second sliding assembly 24 is slid along the lower groove a82 of the window frame 8, the sash 9 is moved back in the direction parallel to the window frame 8, the locking piece 25 gradually approaches the locking seat 26, and the hook part 251 of the second end of the locking piece 25 is raised under the guidance of the guide slope 262. At the same time, the first end of the locking piece 25 gradually descends and is separated from the limiting groove 211 until the position thereof is lower than the second connecting arm 21. At this time, the sash 9 can be pushed inward, which drives the second connecting arm 21 to rotate again until the position thereof is substantially parallel to the second sliding assembly 24. In this process, since the upper end surface of the first end of the locking piece 25 is inclined, the second connecting arm 21 continuously applies downward pressure to the first end of the locking piece 25, which drives the hook part 251 of the second end of the locking piece 25 to continue to rise and tightly engage with the locking protrusion 261, so that the sash 9 can be stably closed on the window frame 8.

[0069] ​As an optional implementation, the first connecting mechanism 1 includes a first hinge assembly and a first sliding assembly 14. The first hinge assembly includes a first connecting arm 11, a first rotating part 12 rotatably connected to the first connecting arm 11, and a first positioning arm 13 disposed on the first rotating part 12. The first rotating part 12 is disposed on the first side slot b93 of the window sash 9. The first positioning arm 13 is disposed on the upper slot b91 of the window sash 9. The first connecting arm 11 is slidably connected to the upper slot a81 of the window frame 8 through the first sliding assembly 14.

[0070] Furthermore, the first rotating part 12 and the first positioning arm 13 are located at the upper corner of the first side of the window sash 9. Specifically, the first bushing 121 of the first rotating part 12 is located at the lower part of the groove b93 on the first side of the window sash 9 and is connected by bolts. The first positioning arm 13 has a convex cross-section and is embedded in the first end of the upper groove b91 of the window sash 9 and is connected by bolts. The first connecting arm 11 connects the first rotating shaft 122 of the first rotating part 12 and the first sliding assembly 14 to transmit rotational and sliding actions. The first sliding assembly 14 is slidably connected to the upper groove a81 to realize the translation of the window sash 9 in a direction parallel to the window frame 8.

[0071] like Figure 2 As shown, when the window sash 9 is in the closed state, the first connecting arm 11 is located above the first positioning arm 13 and is approximately parallel to the plane of the first positioning arm 13 and the window sash 9. At this time, the first sliding component 14 remains in contact with the upper slot a81, but does not slide.

[0072] like Figure 1 As shown, when the window sash 9 needs to be opened, the user manually moves the window sash 9 first along a direction perpendicular to the window frame 8, gradually moving it away from the window frame 8. At this time, the first connecting arm 11 rotates around the first rotating part 12. After the window sash 9 is completely freed from the restraint of the window frame 8, the first connecting arm 11 remains at a specific rotation angle, and the first sliding component 14 slides along the upper groove a81 of the window frame 8, allowing the window sash 9 to move parallel to the window frame 8 until it reaches the opening position required by the user.

[0073] The process of closing the window sash 9 is the reverse of opening it. The user manually moves the window sash 9 in the opposite direction, causing the first sliding component 14 to slide in the opposite direction along the upper groove a81 of the window frame 8. After the hook portion 251 enters the locking groove, the first connecting arm 11 rotates in the opposite direction around the first rotating portion 12. As the window sash 9 gradually approaches the closed position, the first connecting arm 11 gradually rotates to a position approximately parallel to the plane of the first positioning arm 13 and the window sash 9, so that the window sash 9 can be securely closed onto the window frame 8.

[0074] As an optional embodiment, the third connecting mechanism 3 comprises a third hinged assembly and a third sliding assembly 34, the third hinged assembly comprises a third connecting arm 31, a third rotating part 32 rotatably connected with the third connecting arm 31, and a third positioning arm 33 arranged on the third rotating part 32, the third rotating part 32 is arranged on the second side slot a83 of the window frame 8; the third positioning arm 33 is arranged on the upper slot a81 of the window frame 8; the third connecting arm 31 is slidably connected with the upper slot b91 of the window sash 9 through the third sliding assembly 34.

[0075] Further, the third rotating part 32 and the third positioning arm 33 are arranged at the upper corner of the second side of the window frame 8. Specifically, the third shaft sleeve 321 of the third rotating part 32 is embedded in the upper part of the second side slot a83 of the window frame 8 and is connected by bolts. The third positioning arm 33 has a convex cross section and is embedded in the second end of the upper slot a81 of the window frame 8 and is connected by bolts. The third connecting arm 31 is connected between the third rotating shaft 322 of the third rotating part 32 and the third sliding assembly 34, for transmitting the rotating and sliding actions. The third sliding assembly 34 is slidably connected with the upper slot b91, for realizing the translation of the window sash 9 in the direction parallel to the window frame 8.

[0076] As shown in Figure 6 , when the window sash 9 is in the closed state, the third connecting arm 31 is located below the third positioning arm 33 and is in a position substantially parallel to the plane of the third positioning arm 33 and the window frame 8, at this time the third sliding assembly 34 keeps in contact with the upper slot b91 of the window sash 9, but no sliding occurs.

[0077] As shown in Figure 5 , when the window sash 9 needs to be opened, the window sash 9 is first moved in the direction perpendicular to the window frame 8, the third connecting arm 31 rotates around the third rotating part 32, so that after the window sash 9 is completely released from the restraint of the window frame 8, it is smoothly moved along the upper slot b91 through the third sliding assembly 34, realizing the side sliding opening of the window sash 9.

[0078] The process of closing the window sash 9 is opposite to the opening, the third sliding assembly 34 reversely slides along the upper slot b91, the third connecting arm 31 reversely rotates around the third rotating part 32, until the window sash 9 is stably closed on the window frame 8.

[0080] Further, the fourth connecting mechanism 4 is symmetrically arranged with the third connecting mechanism 3. The fourth rotating part 42 and the fourth positioning arm 43 are arranged at the lower corner of the second side of the window frame 8. Specifically, the fourth shaft sleeve 421 of the fourth rotating part 42 is embedded in the lower part of the second side slot a83 of the window frame 8 and connected by bolts. The fourth positioning arm 43 is convex in cross section and is embedded in the second end of the lower slot a82 of the window frame 8 and connected by bolts. The fourth connecting arm 41 is connected between the fourth rotating shaft 422 of the fourth rotating part 42 and the fourth sliding assembly 44 for transmitting the rotating and sliding actions. The fourth sliding assembly 44 is slidingly connected with the lower slot b92 for realizing the translation of the sash 9 in the direction parallel to the window frame 8.

[0081] As shown in Figure 8 , when the sash 9 is closed, the fourth connecting arm 41 is above the fourth positioning arm 43 and is in a position substantially parallel to the plane of the fourth positioning arm 43 and the sash 9, and the fourth sliding assembly 44 keeps in contact with the lower slot b92 but does not slide.

[0082] As shown in Figure 7 , when the sash 9 is opened, the fourth connecting arm 41 rotates around the fourth rotating part 42 so that the sash 9 is smoothly moved along the lower slot b92 by the fourth sliding assembly 44.

[0083] When the sash 9 is closed, the fourth sliding assembly 44 reversely slides, and the fourth connecting arm 41 reversely rotates until the sash 9 is stably closed.

[0084] It should be noted that the rotating structures of the first rotating part 12, the second rotating part 22, the third rotating part 32 and the fourth rotating part 42 all adopt the rotating structure of the existing hinge, which can be selected according to the use requirements, as long as the first connecting arm 11, the second connecting arm 21, the third connecting arm 31 and the fourth connecting arm 41 can rotate around their corresponding rotating structures. Herein, no more description is made.

[0085] As an optional embodiment, as shown in Figure 10 , it further comprises a sliding track 5, which is respectively engaged with the upper slot a81 and the lower slot a82 of the window frame 8; the first sliding assembly 14 and the second sliding assembly 24 are respectively engaged with and slidingly connected with the sliding track 5.

[0086] Further, the sliding track 5 has a C-shaped sliding slot 51 for providing a stable sliding path for the first sliding assembly 14 and the second sliding assembly 24.

[0087] Since the first sliding assembly 14 and the second sliding assembly 24 slide along the upper groove a81 and the lower groove a82 of the window frame 8, the sliding rail 5 cannot be fixedly connected by bolts or rivets. Therefore, part of the sliding rail 5 is embedded in the upper groove a81 and the lower groove a82, and a positioning groove 52 matching the opening end of the upper groove a81 and the lower groove a82 is formed on one side plate, and an extension plate 53 is arranged outside the opening end of the other side plate, so as to tightly fit the sliding rail 5 and the upper groove a81 and the lower groove a82 of the window frame 8.

[0088] When the sliding rail 5 is used, the sizes and specifications of the first mounting shaft 142 and the second mounting shaft 143 of the first sliding assembly 14 and the second pulley 241 of the second sliding assembly 24 are adjusted adaptively.

[0089] As an optional embodiment, the first sliding assembly 14, the second sliding assembly 24, the third sliding assembly 34 and the fourth sliding assembly 44 include pulleys 241 or bearings.

[0090] Further, the first sliding assembly 14, the third sliding assembly 34 and the fourth sliding assembly 44 are the same in structure. Taking the first sliding assembly 14 as an example, as shown in Figure 1 、 Figure 2 、 Figure 14 The first sliding assembly 14 includes a plurality of first sliding parts, a first mounting shaft 142, a second sliding part, a second mounting shaft 143 and a first sliding seat 141. The first sliding part and the second sliding part can select conventional sliding structures in the prior art such as pulleys or bearings according to use requirements. As shown in Figure 14 The first sliding part of the embodiment includes a first bearing 144, and the second sliding part includes a second bearing 145. The first bearing 144 is sleeved on the first mounting shaft 142, the second bearing 145 is sleeved on the second mounting shaft 143, and the first mounting shaft 142 and the second mounting shaft 143 are mounted on the first sliding seat 141. The first sliding seat 141 is rotatably connected to the first connecting arm 11 through a first connecting shaft 146, the rotation axes of the first bearing 144 and the second bearing 145 are perpendicular, i.e. the central axes of the first mounting shaft 142 and the second mounting shaft 143 are perpendicular. The number of the first bearing 144 is four, and two by two symmetrically arranged on both sides of the first sliding seat 141, for sliding contact with the inner top wall and the inner bottom wall of the groove, i.e. the first mounting shaft 142 is two by two symmetrically arranged on both sides of the first sliding seat 141. The number of the second bearing 145 is two, and located at the opening end of the corresponding groove, and forms sliding contact with the edge of the groove, i.e. the two second mounting shafts 143 are arranged at the two end portions of the first sliding seat 141.

[0091] It should be noted that the first sliding part and the second sliding part can select a pulley or a bearing according to the use requirement, and the specific specifications, quantity and layout can be designed according to the use requirement.

[0092] As an optional implementation, as shown in Figure 11 The load wheel 6 is arranged at the lower part of the window frame 8 close to the fourth connecting mechanism 4 and is located on the translation path of the window sash 9 parallel to the window frame 8 and can be slidably matched with the lower groove b92 of the window sash 9.

[0093] The load wheel 6 provides additional support for the window sash 9 when the window sash 9 is translated parallel to the window frame 8, and the load bearing effect is good.

[0094] When the window sash 9 is translated parallel to the window frame 8, the lower groove b92 is slidably matched with the load wheel 6, further improving the stability and smoothness of the movement of the window sash 9.

[0095] When the window sash 9 is moved perpendicular to the window frame 8, the load wheel does not interfere.

[0096] Embodiment 2:

[0097] The difference between this embodiment and embodiment 1 is that, as shown in Figure 12 The load wheel 6 is connected with the window frame 8 through the telescopic guide assembly 7. The guide assembly 7 includes a guide rail 71 and a guide block 72. The guide rail 71 is arranged at the lower part of the window frame 8 close to the fourth connecting mechanism 4, and the guide block 72 is slidably matched with the guide rail 71. The guide block 72 is slidably matched with the guide rail 71 through a bearing or a pulley 241 arranged on the guide block 72, or the guide block 72 is directly slidably matched with the guide rail 71. The load wheel 6 is connected with the second end of the guide block 72 through a mounting seat.

[0098] When the window sash 9 is translated parallel to the window frame 8, the load wheel 6 is slidably matched with the lower groove b92 of the window sash 9, improving the stability of the window sash 9 during translation.

[0099] A follow-up assembly is arranged between the load wheel 6 and the window sash 9, and the follow-up assembly includes a magnet assembly. The magnet assembly includes a first magnet arranged at the second end of the lower groove b92 and a second magnet arranged on the load wheel 6. The polarities of the first magnet and the second magnet are opposite. When the window sash 9 is opened or closed, the magnetic force between the first magnet and the second magnet drives the load wheel 6 to move along the guide rail 71 in the same direction with the guide block 72, improving the stability and load bearing capacity of the window sash 9 during opening and closing.

[0100] The follow-up assembly also includes a shim, which is located at the second end of the lower groove b92. The shim's function is to increase the friction with the load-bearing roller 6. When the window sash 9 is moving, the shim provides friction, driving the load-bearing roller 6 and the guide slider 72 to move along the guide rail 71.

[0101] Example 3:

[0102] like Figure 13 As shown, this embodiment provides a sliding window, including the window connector structure provided in the aforementioned embodiment. By using the connector structure on an existing casement window, the window sash 9 can smoothly and reliably switch between open and closed states, while ensuring the stability and safety of the window sash 9 throughout the entire movement process. This achieves the upgrade from a casement window to a sliding window, reducing construction difficulty and cost. Through the cooperation of the locking member 25 with the limiting groove 211 and the locking groove, the window sash 9 can smoothly move in a horizontal direction parallel or perpendicular to the window frame 8, effectively avoiding unnecessary collisions and wear.
