Description

Technical Field

[0001] The invention relates to the technical field of doors and windows, and in particular to a multi-linked hanging window. Background Art

[0002] Hung windows are windows that open along a horizontal axis. Depending on the position of the hinges and the rotating shaft, hung windows can be divided into top-hung windows and bottom-hung windows. The hinges of top-hung windows are installed on the upper side of the window sash, and they open to the outside at the lower side of the hung window, which has a good rainproof effect. The hinges of bottom-hung windows are installed on the lower side of the window sash, and they open to the room at the upper side of the hung window, which has a good ventilation effect, but is not rainproof.

[0003] When the size of the window is large, such as in an auditorium, hall, etc., in order to avoid setting the size of a single hanging window too large, multiple hanging windows need to be used in combination. In the prior art, the switches of multiple hanging windows are independent of each other. When encountering typhoon weather, users need to close the hanging windows one by one, and open them one by one after the weather clears up, which is time-consuming and laborious, and difficult to deal with emergencies. Summary of the invention

[0004] The present invention aims to provide a multi-linked hanging window to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] According to the multi-linked hanging window of the first embodiment of the present invention, the outer side of the window is an outdoor space, and the inner side of the window is an indoor space, which includes: window frame; There are at least two opening sashes, all of which are arranged in a horizontal direction, and all of which are rotatably connected to the window frame around the same horizontal axis. A linkage structure is provided between every two adjacent opening sashes; the linkage structure comprises an external linkage portion and an internal linkage portion, the external linkage portion is used to push the internal linkage portion outward, and the internal linkage portion is used to push the external linkage portion inward, all of the external linkage portions are provided on the same side of all of the opening sashes, and all of the internal linkage portions are provided on the other side of all of the opening sashes.

[0006] The multi-linked suspended window according to the embodiment of the present invention has at least the following beneficial effects: assuming that the number of opening sashes is three, the three opening sashes are linked step by step through the linkage structure, when the user pushes the first-stage opening sash outward, the outer linkage part of the first-stage opening sash drives the inner linkage part of the second-stage opening sash to move outward, and at the same time, the outer linkage part of the second-stage opening sash drives the inner linkage part of the third-stage opening sash to move outward, thereby realizing the synchronous opening of the three opening sashes; when the user pulls the third-stage opening sash inward, the inner linkage part of the third-stage opening sash drives the outer linkage part of the second-stage opening sash to move inward, and at the same time, the second-stage opening sash The inner linkage part drives the outer linkage part of the first-stage opening fan to move inward, thereby realizing the synchronous closing of the three opening fans; in addition, when the user pushes the third-stage opening fan outward, since the inner linkage part of the third-stage opening fan does not affect the outer linkage part of the second-stage opening fan when moving outward, the third-stage opening fan can be opened separately, and similarly, the first-stage opening fan can also be closed separately to meet different opening and closing window requirements; compared with the prior art, the invention can realize the synchronous opening and closing of multiple opening fans, effectively improve the opening and closing window efficiency, and can realize the closing and opening of a single opening fan to meet different opening and closing window requirements.

[0007] According to some embodiments of the present invention, the upper sides of all opening sashes are connected to the window frame by rotating around the same horizontal axis, and all opening sashes together constitute a top-hung window; or, the lower sides of all opening sashes are connected to the window frame by rotating around the same horizontal axis, and all opening sashes together constitute a bottom-hung window.

[0008] According to some embodiments of the present invention, the outer linkage part and the inner linkage part are both steel-clad rubber strips, and the outer linkage part and the inner linkage part respectively have a first hook and a second hook that are mutually engaged. The rigidity of the steel-clad rubber strip can meet technical requirements and play a role in vibration reduction, and the first hook and the second hook that are mutually engaged can ensure the effective connection between the outer linkage part and the inner linkage part to avoid dislocation.

[0009] According to some embodiments of the present invention, the multi-linked suspended window further includes an automatic locking module, the automatic locking module includes an elastic lock and a lock seat, each notch of the opening sash is connected to the elastic lock, the window frame is connected to the lock seat at the corresponding position of each elastic lock, and the moving path of the elastic lock passes through the corresponding lock seat. When the opening sash is closed, once the elastic lock of the opening sash moves to the lock seat of the window frame, the elastic lock will avoid and automatically lock with the lock seat under the action of elastic force, thereby eliminating the operation of manually locking the window.

[0010] According to some embodiments of the present invention, the lock seat includes a fixed plate, a movable plate and an elastic part, the fixed plate is connected to the window frame, the movable plate is movably connected to the fixed plate along a first straight line, and the elastic part drives the movable plate to reset along a first direction of the first straight line. Through the above-mentioned settings, the movable plate of the lock seat also has elastic avoidance and elastic reset functions, providing technical support for subsequent unlocking.

[0011] According to some embodiments of the present invention, in order to achieve locking of the elastic lock, the movable plate is provided with two baffles, a locking channel parallel to the first straight line is formed between the two baffles, and the movable plate is provided with an abutment surface in the first direction of the locking channel.

[0012] According to some embodiments of the present invention, specifically, the elastic lock includes a mounting plate, a lock tongue and an elastic member, the lock tongue is movably connected to the mounting plate along a second straight line, and the elastic member drives the lock tongue to reset along a second direction of the second straight line.

[0013] According to some embodiments of the present invention, the movement path of the lock tongue passes through the corresponding locking channel, and the lock tongue has an inclined surface that avoids the baffle and a clamping surface that is clamped to the baffle. When the inclined surface of the lock tongue moves to abut against the baffle, under the joint action of the inclined surface and the elastic force, the lock tongue enters the locking channel through elastic avoidance. Once the lock tongue enters the locking channel, under the action of the elastic force, the lock tongue resets to the second direction, and the clamping surface of the lock tongue abuts against the baffle when the window is opened outwards. Since the clamping surface cannot elastically avoid the baffle, the position of the lock tongue is limited in the locking channel to achieve locking of the open window.

[0014] According to some embodiments of the present invention, the automatic lock module also includes a handle and a transmission bar, the number of the handles and the transmission bar is consistent with the number of the elastic locks, each of the opening fans is connected to the handle, each of the mounting plates is connected to a transmission bar, and each of the handles drives a transmission bar to move along the first straight line, so that the lock tongue has a moving path along the first direction across the locking channel, and the abutment surface is located on the moving path of the lock tongue. When it is necessary to unlock the opening sash, first rotate the handle to move the lock tongue across the locking channel in the first direction, and then reset the handle. The lock tongue moves in the opposite direction of the first direction (hereinafter referred to as the first opposite direction) when resetting. Since the lock tongue will extend to the abutment surface of the movable plate under the action of elastic force after passing the locking channel, when the lock tongue is reset, it can apply a force in the first opposite direction to the movable plate through the abutment surface to overcome the elastic force of the movable plate and push the movable plate in the first opposite direction. At this time, the movement of the lock tongue is no longer restricted, so the opening sash can open the window normally. Once the lock tongue leaves the movable plate, the movable plate is reset in the first direction under the action of elastic force, waiting for the next automatic window locking action.

[0015] According to some embodiments of the present invention, the automatic lock module further includes a handle and a transmission bar, the number of the transmission bars is consistent with the number of the elastic locks, the handle is connected to the opening fan at either end, and each of the mounting plates is connected to one of the transmission bars; the first straight line is arranged in the horizontal direction, all the transmission bars are connected together along the first straight line by magnetic force, the handle drives one of the transmission bars to move along the first straight line, so that the lock tongue has a moving path along the first direction across the locking channel, and the abutment surface is located on the moving path of the lock tongue. In order to reduce operations, the number of handles is set to one, and all the transmission bars are driven to move synchronously by one handle. Since the magnetic force is a non-rigid force, the transmission bars connected to each other by magnetic force will not hinder the individual opening of the opening fan.

[0016] According to some embodiments of the present invention, the handle is connected to the opening fan located at the most downstream of the first direction. Since the transmission bar needs to overcome the elastic force of the elastic part of the lock seat when resetting, when the handle is connected to the opening fan located at the most downstream of the first direction, the other transmission bars are driven by thrust when resetting, and thrust is far more reliable than magnetic force, which can ensure the normal resetting of all transmission bars.

DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0024] like Figure 1 and Figure 2 As shown, a multi-linked hanging window according to an embodiment of the first aspect of the present invention includes a window frame 100 and a plurality of opening sashes 200. For example, when there are three opening sashes 200, the size of the window frame 100 can be used to install all the opening sashes 200, and the window frame 100 is provided with two vertically arranged middle braces 110. The three opening sashes 200 are arranged in a horizontal direction, and the arrangement positions of the two middle braces 110 should match the width of the opening sashes 200, and the three opening sashes 200 are installed in this way. If the present technology is applied to a top-hung window, then the upper sides of all the opening sashes 200 are connected to the window frame 100 by rotation around the same horizontal axis, and at this time, all the opening sashes 200 together constitute a top-hung window; if the present technology is applied to a bottom-hung window, then the lower sides of all the opening sashes 200 are connected to the window frame 100 by rotation around the same horizontal axis, and at this time, all the opening sashes 200 together constitute a bottom-hung window. For the convenience of description, the following is a detailed description based on the top-hung window.

[0025] In this embodiment, the outside of the window is used as the outdoor space, that is, the outside direction, the inside of the window is used as the indoor space, that is, the inside direction, the height of the hanging window is used as the up and down direction, and the width of the hanging window is used as the left and right direction.

[0026] The window frame 100 of the present invention is not a window-wrapping structure, and the three opening sashes 200 are all kept outside the window frame 100. When the opening sashes 200 are closed, the opening sashes 200 overlap the outside of the window frame 100, and are sealed with the window frame 100 through the sealing strip 120 to meet the requirements of waterproof and windproof. Since the three opening sashes 200 are all kept outside the window frame 100, the space between two adjacent opening sashes 200 will not be restricted by the middle brace 110.

[0027] like Figure 2 and Figure 3 As shown, a linkage structure 300 is provided between each two adjacent opening sashes 200, and the linkage structure 300 includes an outer linkage part 310 and an inner linkage part 320, and the outer linkage part 310 and the inner linkage part 320 respectively have a first hook 311 and a second hook 321 that are mutually engaged, and the first hook 311 is arranged toward the outside of the window, and the second hook 321 is arranged toward the inside of the window, so that the outer linkage part 310 can push the inner linkage part 320 outward, and the inner linkage part 320 can push the outer linkage part 310 inward. In addition, all the outer linkage parts 310 are arranged on the same side of all the opening sashes 200, and all the inner linkage parts 320 are arranged on the other side of all the opening sashes 200. For example, when all the outer linkage parts 310 are connected to the left notches of all the opening sashes 200, all the inner linkage parts 320 are connected to the right notches of all the opening sashes 200, so as to realize the step-by-step linkage of the three opening sashes 200.

[0028] Specifically, the outer linkage part 310 and the inner linkage part 320 can both be steel-clad rubber strips, the outer side of the rubber strips is made of EPDM rubber, and a steel sheet 330 is added to the middle core, so that the steel sheet 330 and the rubber strips are integrated to increase the hardness, bending resistance and service life of the rubber strips. The rigidity of the steel-clad rubber strips can meet the structural strength and play a role in vibration reduction, reducing the noise caused by collision. The first hook 311 and the second hook 321 that are connected to each other can ensure the effective connection between the outer linkage part 310 and the inner linkage part 320 to avoid dislocation.

[0029] For ease of description, the present embodiment defines three opening fans 200 as a first-stage opening fan 210, a second-stage opening fan 220, and a third-stage opening fan 230. Among them, the first-stage opening fan 210 is only provided with an external linkage part 310, the third-stage opening fan 230 is only provided with an internal linkage part 320, and the second-stage opening fan 220 is provided with an internal linkage part 320 and an external linkage part 310 on both sides. When the user pushes the first-stage opening fan 210 outward, the external linkage part 310 of the first-stage opening fan 210 drives the internal linkage part 320 of the second-stage opening fan 220 to move outward, and at the same time, the external linkage part 310 of the second-stage opening fan 220 drives the internal linkage part 320 of the third-stage opening fan 230 to move outward, thereby realizing the synchronous opening of the three opening fans 200. When the user pulls the third-level opening fan 230 inward, the inner linkage part 320 of the third-level opening fan 230 drives the outer linkage part 310 of the second-level opening fan 220 to move inward. At the same time, the inner linkage part 320 of the second-level opening fan 220 drives the outer linkage part 310 of the first-level opening fan 210 to move inward, thereby realizing the synchronous closing of the three opening fans 200.

[0030] Since the opening range of the top-hung window is fixed, generally 30°, there is no situation where the opening range of the first-stage opening fan 210 is 30°, the opening range of the second-stage opening fan 220 is 20°, and the opening range of the third-stage opening fan 230 is 15°, that is, the top-hung window is either in an open state or in a closed state. The invention can realize the synchronous opening and closing of multiple opening fans 200, effectively improving the efficiency of window opening and closing. When encountering strong convective weather, all opening fans 200 can be quickly closed, and all opening fans 200 can be quickly opened after clearing.

[0031] In addition, when the user pushes the third-stage opening fan 230 outward, the third-stage opening fan 230 can be opened separately because the inner linkage part 320 of the third-stage opening fan 230 does not affect the outer linkage part 310 of the second-stage opening fan 220 when moving outward. Similarly, when the user pulls the first-stage opening fan 210 inward, the outer linkage part 310 of the first-stage opening fan 210 does not affect the inner linkage part 320 of the second-stage opening fan 220 when moving inward, so the first-stage opening fan 210 can be closed separately to meet different window opening and closing requirements.

[0032] If all the opening fans 200 are in the closed state, when the user only wants to open one of the three opening fans 200, the best option is to directly open the third-level opening fan 230. When the user only wants to open two of the three opening fans 200, the best option is to directly open the second-level opening fan 220, which will drive the third-level opening fan 230 to open synchronously when the second-level opening fan 220 is opened; the second best option is to directly open the first-level opening fan 210, which will drive the second-level opening fan 220 and the third-level opening fan 230 to open synchronously when the first-level opening fan 210 is opened, and then close the first-level opening fan 210 alone.

[0033] If all the opening fans 200 are in the open state, when the user only wants to close one of the three opening fans 200, the best option is to directly close the first-stage opening fan 210. When the user only wants to close two of the three opening fans 200, the best option is to directly close the second-stage opening fan 220, which will drive the first-stage opening fan 210 to open synchronously when the second-stage opening fan 220 is closed; the second best option is to directly close the third-stage opening fan 230, which will drive the second-stage opening fan 220 and the first-stage opening fan 210 to close synchronously when the third-stage opening fan 230 is closed, and then open the third-stage opening fan 230 alone.

[0034] Since it is difficult to distinguish the first-stage opening sash 210, the second-stage opening sash 220 and the third-stage opening sash 230 of the multi-linked hanging window in appearance, it is best to affix corresponding labels and corresponding operation instructions on the surface of the corresponding opening sash 200. For example, a "synchronous window opening" label is affixed on the surface of the first-stage opening sash 210 to remind the user that the synchronous window opening can be achieved by opening the opening sash 200; for example, a "synchronous window closing" label is affixed on the surface of the third-stage opening sash 230 to remind the user that the synchronous window closing can be achieved by closing the opening sash 200.

[0035] When encountering strong winds, the high-pressure airflow may blow the opening fan 200 from the open state to the closed state, and cause the opening fan 200 to generate high-frequency vibration under the continuous wind pressure, which in turn damages the hardware of the opening fan 200, and in severe cases, causes the opening fan 200 to fall off. In order to overcome the above technical problems, it is necessary to introduce an automatic locking module 40 in the multi-linked hanging window. When the opening fan 200 enters the closed state from the open state, the automatic locking module 40 is activated, so that the opening fan 200 remains in the closed state, so as to avoid the opening fan 200 from generating high-frequency vibration between the open state and the closed state, and lock the opening fan 200 to meet the requirements of windproof and waterproof.

[0036] like Figure 4 and Figure 5As shown, specifically, the automatic lock module 40 includes an elastic lock 500 and a lock seat 400, each of the notches of the opening sash 200 is connected with an elastic lock 500, and the window frame 100 is connected with a lock seat 400 at a corresponding position of each elastic lock 500. The lock seat 400 includes a fixed plate 410, a backing plate 420, a movable plate 430 and an elastic portion 440, and first wing plates 411 are provided on both sides of the fixed plate 410, and the middle part of the fixed plate 410 is convex toward the front, thereby forming a first concave position 412 on the back of the fixed plate 410, and the two first wing plates 411 are provided with mounting holes 413, and the fixed plate 410 is fixedly connected to the notch of the window frame 100 through screws and the mounting holes 413. A slide groove 414 is provided in the middle of the fixed plate 410 along its length direction. In this embodiment, the setting direction of the slide groove 414 is defined as a first straight line. The movable plate 430 and the pad plate 420 are respectively located on the front and back sides of the slide groove 414. The pad plate 420 is received in the first recess 412. The movable plate 430 and the pad plate 420 are connected by a connecting member, which passes through the slide groove 414 and slides along the slide groove 414. The pad plate 420 is provided with two first mounting posts 421. The fixed plate 410 is provided with two second mounting posts 415 on the side facing the pad plate 420, that is, the back of the fixed plate 410 is provided with two second mounting posts 415. The elastic part 440 is provided with two and can be optionally a tension spring. The two ends of each tension spring are respectively connected to the first mounting post 421 and the second mounting post 415, so that the pad plate 420 and the movable plate 430 can be elastically movable along the first straight line. At this time, the tension spring can drive the movable plate 430 to reset along the first direction of the first straight line.

[0037] In order to achieve the locking of the elastic lock 500, the movable plate 430 is provided with two baffles 431, and a locking channel 432 parallel to the first straight line is formed between the two baffles 431. The movable plate 430 is provided with an abutment surface 433 in the first direction of the locking channel 432. Correspondingly, the elastic lock 500 includes a mounting plate 510, a bottom shell 520, a locking tongue 530 and an elastic member 540. Second wing plates 511 are provided on both sides of the mounting plate 510. The middle part of the mounting plate 510 is convex toward the front and is provided with a locking hole 512, so as to form a second concave position 513 on the back of the mounting plate 510. The two second wing plates 511 are provided with a connecting hole 514. The mounting plate 510 is fixedly connected to the notch of the opening fan 200 through screws and the connecting hole 514. The bottom shell 520 is located in the second recess 513. The bottom shell 520 is connected to the mounting plate 510 through a connecting piece. An elastic piece 540 and a lock tongue 530 are provided inside the bottom shell 520. The elastic piece 540 can be optionally a compression spring. The lock tongue 530 passes through the lock hole 512 and retracts and contracts along a straight line under the elastic force of the compression spring. In this embodiment, the retracting direction of the lock tongue 530 is defined as a second straight line. At this time, the compression spring can drive the lock tongue 530 to reset along the second direction of the second straight line.

[0038] For ease of description, this embodiment defines the opposite direction of the first direction as the first opposite direction, and defines the opposite direction of the second direction as the second opposite direction. It should be noted that the first straight line and the second straight line are straight lines in different directions, and can be set at any angle except that they cannot be set in parallel.

[0039] Furthermore, the movement path of the lock tongue 530 passes through the corresponding locking channel 432. One side of the lock tongue 530 has an inclined surface 531 that avoids the baffle 431, and the other side of the lock tongue 530 has a clamping surface 532 that is clamped to the baffle 431. When the inclined surface 531 of the lock tongue 530 moves to abut against the baffle 431, under the joint action of the inclined surface 531 and the compression spring, the lock tongue 530 enters the locking channel 432 by elastic avoidance. Once the lock tongue 530 enters the locking channel 432, under the elastic force of the compression spring, the lock tongue 530 resets to the second direction. At this time, the clamping surface 532 of the lock tongue 530 will be clamped to the baffle 431 when the window is opened outwards. Since the clamping surface 532 cannot be elastically evaded with the baffle 431, the position of the lock tongue 530 is limited in the locking channel 432 to achieve the locking of the opening fan 200.

[0040] When the user or strong wind switches the opening fan 200 from the open state to the closed state, the opening fan 200 drives the lock tongue 530 to move toward the baffle 431 during the closing process. The lock tongue 530 retracts in the second reverse direction under the joint action of the inclined surface 531 and the compression spring, causing the lock tongue 530 to pass over the baffle 431 and enter the locking channel 432. Once the lock tongue 530 enters the locking channel 432, under the elastic force of the compression spring, the lock tongue 530 is reset to the second direction. At this time, the locking surface 532 of the lock tongue 530 will be locked to the baffle 431 when the window is opened outward, causing the opening fan 200 to be unable to be opened outward and in a locked state. That is, once the opening fan 200 is closed, the elastic lock 500 and the lock seat 400 are automatically locked to save the operation of manually locking the window. At this time, the opening fan 200 cannot be opened outward without applying external force.

[0041] In order to be able to open the opening fan 200 in the locked state, the automatic lock module 40 also includes a handle 600 and a transmission bar 610. In this embodiment, the first straight line is set in the up-down direction. At this time, the first straight lines of all the opening fans 200 cannot be connected in a straight line, so the number of handles 600 and transmission bars 610 is consistent with the number of elastic locks 500, and the three are all three. The three handles 600 are connected to the corresponding opening fan 200 through their respective connecting members, and each mounting plate 510 is fixedly connected to a transmission bar 610 located in the notch through screws and connecting holes 514. The three handles 600 are respectively connected to the three transmission bars 610 in transmission connection, and each handle 600 drives the corresponding transmission bar 610 to move along the first straight line, so that the lock tongue 530 has a moving path along the first direction across the locking channel 432, and at this time the abutment surface 433 is located on the moving path of the lock tongue 530.

[0042] When the door 200 needs to be unlocked, the elastic lock 500 and the lock seat 400 are in the state as shown in FIG. Figure 6 First, the handle 600 is rotated to make the lock tongue 530 pass through the locking channel 432 in the first direction. After passing through the locking channel 432, the lock tongue 530 extends to the abutting surface 433 of the movable plate 430 under the elastic force of the compression spring. At this time, the elastic lock 500 and the lock seat 400 are in the following state. Figure 7 Then, the handle 600 is reset, and the lock tongue 530 moves in the first reverse direction when reset. During the reset process, the lock tongue 530 can exert a force in the first reverse direction on the movable plate 430 through the abutment surface 433 to overcome the elastic force of the tension spring and push the movable plate 430 in the first reverse direction. At this time, the elastic lock 500 and the lock seat 400 are in the following state. Figure 8 In the reset state shown, the movement of the lock tongue 530 is no longer subject to any restriction, so the opening fan 200 can open the window normally. Once the lock tongue 530 leaves the movable plate 430, the movable plate 430 is reset toward the first direction under the elastic force of the extension spring, waiting for the next automatic window locking action.

[0043] It should be noted that, since the three transmission bars 610 cannot be connected in a straight line, three handles 600 need to be provided to respectively control the relative positions of the three transmission bars 610. That is to say, before opening the window, the three handles 600 need to be manipulated to respectively unlock the three opening sashes 200. Of course, after rotating the handle 600, the handle 600 can also be reset after opening the opening sash 200, and the final result is to ensure that the moving path of the lock tongue 530 can pass through the corresponding locking channel 432.

[0044] like Figure 1As shown, in order to further simplify the operation, in other embodiments, the first straight line is set along the left and right direction. At this time, the first straight lines of all the opening sashes 200 can be connected along the straight line, so the number of transmission bars 610 is consistent with the number of elastic locks 500, both of which are three, but only one handle 600 is required. The handle 600 is connected to the opening sash 200 at any end through a connecting piece, and each mounting plate 510 is fixedly connected to a transmission bar 610 located in the notch through a screw and a connecting hole 514. The handle 600 is connected to a transmission bar 610 in a transmission manner, and all transmission bars 610 are connected together along the first straight line through magnetic force. The handle 600 drives all transmission bars 610 to move along the first straight line, so that the lock tongue 530 has a moving path that passes over the locking channel 432 along the first direction. At this time, the abutting surface 433 is located on the moving path of the lock tongue 530.

[0045] Specifically, all transmission bars 610 may be selected as magnetic components, or the ends of each transmission bar 610 may be connected with magnetic components (not shown in the drawings) to achieve magnetic connection of all transmission bars 610. When all opening sashes 200 are in the same position, such as opening or closing windows at the same time, all transmission bars 610 are arranged along a straight line and connected by magnetic force. Since magnetic force is a non-rigid force, the transmission bars 610 connected to each other by magnetic force will not hinder the individual opening of the opening sashes 200.

[0046] It can be understood that along the first direction, the first direction is from the upstream position to the downstream position, that is, the first direction is from the right to the left. In the present invention, there are two settings for the handle 600. The handle 600 can be connected to the opening fan 200 located at the most upstream in the first direction. At this time, the user drives the corresponding transmission bar 610 to move along the first direction by rotating the handle 600, and the other transmission bars 610 move in the first direction under the action of the thrust. When the handle 600 is reset, it drives the corresponding transmission bar 610 to move in the first reverse direction, and the other transmission bars 610 move in the first reverse direction under the action of the magnetic force. On the other hand, the handle 600 can also be connected to the opening fan 200 located at the most downstream in the first direction. At this time, the user drives the corresponding transmission bar 610 to move along the first direction by rotating the handle 600, and the other transmission bars 610 move in the first direction under the action of the magnetic force. When the handle 600 is reset, it drives the corresponding transmission bar 610 to move in the first opposite direction, and the other transmission bars 610 move in the first opposite direction under the action of the thrust.

[0047] If the handle 600 is connected to the opening fan 200 located at the most upstream of the first direction, since the transmission bar 610 is connected by magnetic force when resetting, the magnetic force at this time needs to overcome the elastic force of the tension spring. Therefore, in order to make the magnetic connection of all transmission bars 610 more secure and avoid disconnection between the transmission bars 610 due to insufficient magnetic force during resetting, the connection ends of two adjacent transmission bars 610 are connected with strong magnets, which can be neodymium iron boron magnets. The size of the strong magnet is larger than the size of the transmission bar 610, and the opening fan 200 is provided with a clearance position to avoid the strong magnet. In addition to using strong magnets, this embodiment also increases the size of the strong magnets and sets clearance positions to prevent interference.

[0048] If the handle 600 is connected to the opening fan 200 located at the most downstream of the first direction, since the transmission bar 610 is connected by magnetic force when moving in the first direction, the magnetic force at this time does not need to overcome the elastic force of the tension spring, so the magnetic force does not need to be set very large to meet the working conditions. On the other hand, the other transmission bars 610 are driven by thrust during resetting, and thrust is much more reliable than magnetic force, and there is no disconnection, which can ensure the normal resetting of all transmission bars 610. Therefore, compared with the previous embodiment, this embodiment does not need to set a strong magnet to meet the working conditions, and is more reliable. In summary, it is preferred to connect the handle 600 to the opening fan 200 located at the most downstream of the first direction, that is, Figure 1 Settings shown.

[0049] It should be further explained that, for the embodiment using only one handle 600, after rotating the handle 600, the handle 600 can be reset after opening the opening sash 200, but since part of the transmission bars 610 are simultaneously set in the notches of the two opening sashes 200, this operation cannot realize the individual opening of the opening sash 200, otherwise it will cause deformation or breakage of the transmission bars 610. In addition, for the embodiment using three handles 600, the first straight line can also be set in the left and right direction, and at this time all the transmission bars 610 are not connected along the straight line, but are arranged at intervals along the straight line, and each transmission bar 610 is controlled by the corresponding handle 600. This setting can realize the synchronous opening of all the opening sashes 200, and can also realize the individual opening of the opening sash 200.

[0050] In some embodiments of the present invention, in order to facilitate the operation of the opening sash 200, for the opening sash 200 with the handle 600, the handle 600 can be used as a force point for opening and closing the window, and for the opening sash 200 without the handle 600, a handle 700 needs to be connected as a force point for opening and closing the window. Of course, the opening sash 200 can also have both the handle 600 and the handle 700, and is not limited to the above embodiments.

[0051] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
