Description

Technical Field

[0001] The present invention relates to the technical field of building doors and windows, especially the broken bridge sliding window with sound insulation and heat insulation. Background Art

[0002] The existing traditional sliding window has a relatively simple structure. The adjacent two window sashes are only sealed by simple wool strips, and the sealing performance is poor, resulting in poor heat insulation and sound insulation performance. Especially in an environment with large temperature differences or high noise, it cannot effectively block the influence of the external environment on the interior. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: to provide a broken bridge sliding window with sound insulation and heat insulation, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0004] The solution of the present invention to solve its technical problem is:

[0005] The broken bridge sliding window with sound insulation and heat insulation is provided with a first direction, a second direction, and a third direction, and the first direction, the second direction, and the third direction are perpendicular to each other in pairs; the broken bridge sliding window includes:

[0006] A window frame, provided with a frame opening, and the frame opening is provided with a first guiding structure and a second guiding structure;

[0007] A plurality of window sashes, which are installed in the frame opening; the window sashes are slidably connected to the first guiding structure or the second guiding structure in a switchable manner; the first guiding structure enables the window sashes to slide relative to the window frame along the first direction; the second guiding structure enables the window sashes to slide relative to the window frame along the second direction;

[0008] The window sashes are installed with a transmission assembly and a handle assembly, and the handle assembly is rotatably connected to the window sashes;

[0009] Wherein, at least one side sealing structure is provided between two adjacent window sashes; the side sealing structure includes;

[0010] A side sealing strip, which can extend or retract into the window sash along the first direction;

[0011] An adjacent sash locking component, which includes two sealing and locking components; the two sealing and locking components are respectively arranged at one end of two adjacent window sashes close to each other, and at least one of the two sealing and locking components is movably connected to the corresponding window sash;

[0012] The handle assembly is drivingly connected to the side sealing strip and the adjacent sash locking component through the transmission component to drive the side sealing strip and the adjacent sash locking component to switch between the locked state and the normal state;

[0013] In the locked state, the two sealing and locking components are locked, and the side sealing strip abuts against the end face of the adjacent window sash; in the normal state, the two sealing and locking components are separated, and the side sealing strip is received into the window sash.

[0014] With the above technical solution, when it is necessary to seal between two adjacent window sashes, the user first arranges the two window sashes in a row along the first direction, and then operates the handle assembly to lock the two sealing and locking components, and the side sealing strip abuts against the end face of the adjacent window sash to complete the sealing between the two adjacent window sashes.

[0015] As a further improvement of the above technical solution, the sealing and locking component includes:

[0016] A driving seat, which is slidably connected to the window sash along the third direction;

[0017] A locking member, which is slidably connected to the driving seat along the third direction;

[0018] A locking return member, which is arranged between the locking member and the driving seat;

[0019] There are two locking linkage rods. One ends of the two locking linkage rods are respectively hinged to the driving seat and the locking member, and the other ends are hinged to each other. The end where the two locking linkage rods are hinged to each other is set as the second hinge end, and the side sealing strip moves along the first direction with the second hinge end.

[0020] In the locked state, the locking member and the driving seat are misaligned; in the normal state, the locking member and the driving seat are aligned; when the locking member moves from the normal state to the locked state, the two locking linkage rods drive the side sealing strip to extend out of the window sash.

[0021] With the above technical solution, let the two adjacent window sashes that need to be sealed and locked be the first window sash and the second window sash. The process of sealing and locking the first window sash and the second window sash is as follows:

[0022] The user first pulls the first window sash into the room, and then the user moves the second window sash to the side of the locking seat end of the first window sash and pulls the second window sash into the room to make the second window sash flush with the first window sash. Then rotate the handle assembly to lock the locking members of the first window sash and the second window sash.

[0023] During the locking process of the locking components of the first window sash and the second window sash, after the two locking components are locked, the driving seat still needs to continue moving a certain distance to a specified position. During the continuous movement of the driving seat, the locking component will be misaligned with the corresponding driving seat, and the sealing lock seat will also be misaligned with the corresponding driving seat. The sealing lock point and the sealing lock seat will both enter the locked state. At this time, due to the misalignment of the two locking components relative to their respective corresponding driving seats, the two locking linkage rods will drive the side sealing strip to extend out of the window sash, so that the side sealing strip abuts against the adjacent window sash. Thus, the sealing between two adjacent window sashes is realized.

[0024] Since the two window sashes of the sliding window in the prior art are arranged with a front-back misalignment, and only simple wool strips are used for sealing between two adjacent window sashes, compared with the prior art, this solution makes the sealing performance of two adjacent window sashes better, thereby making the heat insulation and sound insulation performance of the broken bridge sliding window of this solution better.

[0025] As a further improvement of the above technical solution, it further includes a connecting driving member. The second hinged ends of the two locking linkage rods are both hinged to the connecting driving member, and the side sealing strip is slidably connected to the connecting driving member in the up-down direction.

[0026] Through the above technical solution, since the locking linkage rod will additionally drive the connecting driving member to move up and down during movement, the side sealing strip only needs to move in the left-right direction and does not need to move in the up-down direction. By arranging the connecting driving member between the locking linkage rod and the side sealing strip and making the connecting driving member slid in the up-down direction with the side sealing strip, the up-down displacement of the side sealing strip can be effectively avoided.

[0027] As a further improvement of the above technical solution, a frame-sash locking position assembly is provided between the window frame and the window sash. The frame-sash locking position assembly includes:

[0028] A frame-sash lock seat, which is fixed to the end of the window frame in the third direction; the frame-sash lock seat is provided with a frame-sash locking position groove;

[0029] A frame-sash lock point, which is matched with the frame-sash lock seat, and the frame-sash lock point is installed on the window sash; the handle assembly drives the frame-sash lock point to move relative to the window sash through the transmission assembly, so that the frame-sash lock point enters or exits the frame-sash locking position groove along the first direction.

[0030] As a further improvement of the above technical solution, a frame edge sealing strip is fixed in the frame opening. The frame edge sealing strip is provided with a frame edge sealing surface, and the frame edge sealing surface is used to abut against the end surface of the window sash in the second direction to form a seal.

[0031] Through the above technical solution, the setting of the frame edge sealing strip can enhance the sealing performance between the window frame and the window sash, thereby improving the heat insulation and sound insulation performance of this broken bridge sliding window.

[0032] As a further improvement of the above technical solution, a lock point linkage is provided between the frame-sash lock point and the transmission assembly. The two ends of the lock point linkage are respectively hinged to the transmission assembly and the frame-sash lock point.

[0033] The window sash is provided with a lock point guide groove, and the lock point guide groove is provided with a first guide groove and a second guide groove; the first guide groove is arranged on one side of the second guide groove away from the frame-sash lock base.

[0034] The frame-sash lock point moves along the lock point guide groove; when the frame-sash lock point moves along the first guide groove, the frame-sash lock point approaches or moves away from the frame-sash lock base along the second direction; when the frame-sash lock point moves along the second guide groove, the frame-sash lock point enters or disengages from the frame-sash lock position groove along the first direction.

[0035] The notch of the frame-sash lock position groove is provided with a sealing push part, which is correspondingly arranged with the first guide groove, and the sealing push part is used to limit the frame-sash lock point; during the movement of the frame-sash lock point along the first guide groove, when the frame-sash lock point contacts the sealing push part, the lock point linkage swings around the frame-sash lock point to push the transmission assembly and the window sash closer to the frame edge sealing strip.

[0036] By setting the first guide groove and the second guide groove, in the non-locked state, the frame-sash lock point is located in the first guide groove, and the frame-sash lock point and the frame-sash lock base are misaligned. The frame-sash lock base and the frame-sash lock point will not interfere with the left and right movement of the window sash, thus ensuring the normal operation of the basic functions of the broken bridge sliding window.

[0037] During the movement of the frame-sash lock point along the first guide groove, when the frame-sash lock point contacts the sealing push part, the position of the frame-sash lock point is restricted by the sealing push part, and the frame-sash lock point cannot continue to move further in the front-back direction. At this time, since the transmission system is still working, the transmission rod will continue to move, causing the lock point linkage to swing around its hinge position with the frame-sash lock point, thereby pushing the transmission assembly and the window sash closer to the frame edge sealing strip, making the window sash sealed with the window frame to improve the sealing performance of this broken bridge sliding window, and thus improving the heat insulation and sound insulation performance.

[0038] When the window sash and the window frame are in the locked state, the frame-sash lock point is arranged in the second guide groove, and the frame-sash lock point is inserted into the frame-sash lock position groove and locked with the frame-sash lock base, and the window sash cannot move back and forth relative to the window frame, thus ensuring the locking of the window sash and the window frame.

[0039] As a further improvement of the above technical solution, the window frame includes a first frame body, a frame body heat break, and a second frame body arranged in sequence along the second direction;

[0040] The window sash includes a first sash body, a sash body heat break, and a second sash body arranged in sequence along the second direction.

[0041] As a further improvement of the above technical solution, the number of the side sealing strips in the sealing and locking assembly is set to two. The two side sealing strips are respectively arranged on the first sash body and the second sash body, and the two side sealing strips are fixed by a plurality of sealing strip connecting rods;

[0042] The first sash body, the sash body heat break, and the second sash body are all provided with connecting rod sliding grooves. The sealing strip connecting rods pass through the connecting rod sliding grooves of the first sash body, the sash body heat break, and the second sash body, and the sealing strip connecting rods are slidably connected with the connecting rod sliding grooves in the left - right direction.

[0043] Through the above technical solution, setting a plurality of side sealing strips can enhance the sealing performance between two adjacent window sashes.

[0044] As a further improvement of the above technical solution, the handle assembly includes:

[0045] A handle rotating seat, which is rotatably connected with the window sash;

[0046] A handle main body, which is provided with a handle hinged end and a handle control end. The handle hinged end is hinged with the handle rotating seat;

[0047] A handle reset member, which is arranged between the handle main body and the handle rotating seat. The handle reset member makes the handle control end have a tendency to approach the handle rotating seat;

[0048] The window sash is provided with two handle receiving grooves arranged perpendicular to each other, and the handle receiving grooves are used for receiving the handle main body;

[0049] The handle control end is provided with a finger insertion groove.

[0050] Through the above technical solution, by setting the handle receiving grooves, when the handle main body is not needed, the handle main body is flush with the end face of the window sash. The handle main body will not hinder the window sash from sliding in the left - right direction, which can avoid hindering the user's pushing and pulling operation, and enables the positions of multiple window sashes to be exchanged, and also enables multiple window sashes to be stacked flatly, so that the exit when the broken - bridge sliding window is fully opened becomes larger.

[0051] As a further improvement of the above technical solution, the transmission assembly includes:

[0052] The first driving gear rotates along with the handle assembly.

[0053] The first driving rack engages with the first driving gear.

[0054] A plurality of transmission rods are slidably connected to the window sash, and one of the transmission rods is fixedly connected to the first driving rack; the plurality of transmission rods are respectively arranged on four sides of the window sash.

[0055] The steering transmission member has two ends respectively fixed to two adjacent transmission rods.

[0056] The beneficial effect of the present invention is that the heat insulation and sound insulation performance of the broken bridge sliding window in this solution is better.

[0057] The present invention is used in the technical field of building doors and windows. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0070] The concept, specific structure and technical effects of the present invention will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present invention. In addition, all the connection / connection relationships mentioned in the text do not refer to the direct connection of components alone, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present invention can be combined with each other without conflicting with each other.

[0071] There are a first direction, a second direction and a third direction, and the first direction, the second direction and the third direction are perpendicular to each other in pairs. Specifically, in this embodiment, the first direction is set as the left-right direction, parallel to the X axis in the figure; the second direction is set as the indoor-outdoor direction, parallel to the Y axis in the figure; the third direction is set as the up-down direction, parallel to the Z axis in the figure.

[0072] Refer toFigure 1 and Figure 2 , a broken bridge sliding window with sound insulation and heat insulation, comprising a window frame 100 and a window sash 200.

[0073] The window frame 100 is provided with a frame opening. Refer to Figure 1 、 Figure 2 、 Figure 6 , a frame side sealing strip 150 is installed inside the frame opening. The frame side sealing strip 150 has a rectangular structure. The frame side sealing strip 150 is provided with a frame side sealing surface arranged forward or backward. Specifically, in this embodiment, the frame side sealing surface of the frame side sealing strip 150 is arranged backward (towards the outside), and the frame side sealing surface is used to form a seal with the front end surface of the window sash 200. In other embodiments, the frame side sealing surface can also be arranged forward. Correspondingly, the frame side sealing surface abuts against the rear end surface of the window sash 200 to form a seal. By setting the frame side sealing strip 150, the sealing performance between the window sash 200 and the window side can be effectively improved.

[0074] Refer to Figure 1 、 Figure 2 、 Figure 6 , the window frame 100 includes a first frame body 110, a frame body broken bridge 120, and a second frame body 130 arranged in sequence along the front-rear direction (the front-rear direction refers to the indoor-outdoor direction, the same below). The first frame body 110 is arranged indoors, the second frame body 130 is arranged outdoors, and the frame body broken bridge 120 is arranged between the first frame body 110 and the second frame body 130. The frame body broken bridge 120 is used to achieve the function of thermal break, block the conduction of internal and external heat, and effectively improve the heat insulation performance of the frame body.

[0075] The frame body broken bridge 120 arranged in the middle is made of thermoplastic polyamide or glass fiber reinforced nylon, and has excellent heat insulation, corrosion resistance and strength performance, and can effectively block the conduction of indoor and outdoor heat.

[0076] The frame body broken bridge 120 is connected to the first frame body 110 and the second frame body 130 through a standardized connection structure. Those skilled in the art can select the structure of the insert strip of the frame body broken bridge 120 according to actual needs.

[0077] The window frame 100 further includes a heat insulation cover plate 140. The material of the heat insulation cover plate 140 is the same as that of the heat insulation strip, and has the function of blocking heat transfer. The heat insulation cover plate 140 is arranged at the upper and lower ends of the frame opening, and the heat insulation cover plate 140 covers the first frame body 110, the frame body broken bridge 120, and the second frame body 130.

[0078] Refer to Figure 1 、 Figure 2 、 Figure 3, a first guiding structure and a second guiding structure are provided inside the frame opening. Both the first guiding structure and the second guiding structure are arranged on the heat insulation cover plate 140. In this embodiment, the first guiding structure is arranged as a transverse movement groove 170, the transverse movement groove 170 extends horizontally left and right, the second guiding structure is arranged as a vertical movement groove 180, the vertical movement groove 180 extends vertically forward and backward, and the transverse movement groove 170 and the vertical movement groove 180 are connected, so that the transverse movement groove 170 and the vertical movement groove 180 together form a net-like groove structure.

[0079] Specifically, in this embodiment, the number of the vertical movement grooves 180 is set to six, the six vertical movement grooves 180 are arranged in parallel with each other, every three vertical movement grooves 180 correspond to one window sash 200, and the vertical movement grooves 180 extend in the front-back direction; the number of the transverse movement grooves 170 is set to four, the four transverse movement grooves 170 are arranged in parallel with each other, every two transverse movement grooves 170 are matched with one window sash 200, and the transverse movement grooves 170 extend in the horizontal direction.

[0080] Specifically, in this embodiment, the number of the window sashes 200 is set to two. In other embodiments, the number of the window sashes 200 can also be set to three, four or other numbers to meet the needs of customers. When the number of the window sashes 200 is set to three, the number of the transverse movement grooves 170 needs to be set to six, and the number of the vertical movement grooves 180 needs to be set to nine. The corresponding numbers of the transverse movement grooves 170 and the vertical movement grooves 180 can be obtained by analogy for other numbers of the window sashes 200.

[0081] Refer to Figure 2 、 Figure 3 、 Figure 5 , specifically, in this embodiment, the window sash 200 includes a first sash body 210, a sash heat break 220 and a second sash body 230. The first sash body 210, the sash heat break 220 and the second sash body 230 are arranged in sequence in the front-back direction. The first sash body 210 is arranged indoors, the second sash body 230 is arranged outdoors, and the sash heat break 220 is arranged between the first sash body 210 and the second sash body 230. The sash heat break 220 is used to realize the heat break function and block the heat conduction between indoors and outdoors, so as to effectively improve the heat insulation performance of the window sash 200.

[0082] Specifically, in this embodiment, the first sash body 210 is arranged on the side of the second sash body 230 close to the frame edge sealing strip 150. The thickness of the first sash body 210 in the front-back direction is greater than the thickness of the second sash body 230 in the front-back direction, so as to reserve enough space for installing accessories for the first sash body 210.

[0083] Specifically, guiding balls 240 are respectively installed at the upper and lower ends of the window sash 200. In this embodiment, the number of the guiding balls 240 is set to six, and the six guiding balls 240 are arranged in a matrix of three left and right and two front and back to correspond to the transverse movement groove 170 and the vertical movement groove 180, and the guiding balls 240 are in sliding fit with the transverse movement groove 170 and the vertical movement groove 180.

[0084] By providing a horizontal translation groove 170, a vertical translation groove 180, and a guiding ball 240, the window sash 200 can be translated in the left - right direction and can slide in the front - back direction at specific positions (when the guiding balls 240 of the window sash 200 respectively correspond to the three vertical translation grooves 180), so that multiple window sashes 200 can ultimately be in a flush state, which is conducive to the sealing between two adjacent window sashes 200.

[0085] The guiding ball 240, the horizontal translation groove 170, and the vertical translation groove 180 enable the window sash 200 to slide stably and smoothly, thereby enhancing the opening and closing experience of the entire window, and enabling the window sash 200 to move in the front - back direction and the left - right direction, so that multiple window sashes 200 can ultimately be flush.

[0086] The left and right ends of the window sash 200 are respectively set as a lock point end and a lock seat end, and the left and right end faces of the window sash 200 are set as side sealing end faces.

[0087] Refer to Figure 2 、 Figure 4 、 Figure 7 , the window sash 200 is equipped with a side sealing structure, a transmission assembly, and a handle assembly 500.

[0088] The handle assembly 500 is rotatably connected to the window sash 200. Specifically, in this embodiment, the handle assembly 500 includes: a handle rotating seat 510, a handle main body 520, and a handle reset member (the handle reset member is not shown in the figure).

[0089] The handle rotating seat 510 is rotatably installed on the window sash 200, and the handle rotating seat 510 is provided with a slot for accommodating the handle main body 520.

[0090] The two ends of the handle main body 520 are respectively set as a handle control end 521 and a handle hinge end 522. The handle hinge end 522 is rotatably connected to the handle rotating seat 510.

[0091] The handle reset member is an elastic member. Specifically, in this embodiment, the handle reset member is set as a torsion spring. In other embodiments, the handle reset member can also be set as a spring or other structures. Those skilled in the art can select the specific structure of the handle reset member according to actual needs. The handle reset member is arranged between the handle rotating seat 510 and the handle main body 520.

[0092] The handle main body 520 has two states, which are respectively set as a sealing state and a normal state. In the sealing state, the handle main body 520 is parallel to the up - down direction, and in the normal state, the handle main body 520 is parallel to the left - right direction.

[0093] Specifically, in this embodiment, the handle control end 521 is provided with a finger insertion groove 523 that penetrates the handle control end 521 in the front-rear direction. The finger insertion groove 523 is used for the user to insert a finger. After the user's finger is inserted, the handle control end 521 is pulled to swing outward by the friction with the inner wall of the finger insertion groove 523, and then the handle assembly 500 can be driven to rotate around an axis parallel to the front-rear direction.

[0094] Specifically, the sash 200 is provided with handle receiving grooves 250. The number of the handle receiving grooves 250 is set to two, and the two handle receiving grooves 250 are arranged perpendicular to each other. The handle receiving grooves 250 are used to receive the handle body 520. The handle body 520 is received in the two handle receiving grooves 250 respectively in the sealed state and the normal state.

[0095] By providing the handle receiving grooves 250, when the handle body 520 is not needed, the handle body 520 is flush with the end face of the sash 200. The handle body 520 will not hinder the sash 200 from sliding in the left-right direction, which can avoid hindering the user from performing the pushing and pulling operation. And it enables the positions of multiple sashes 200 to be swapped, makes the exit larger when the broken bridge sliding window is fully opened, and also enables multiple sashes 200 to be stacked flush.

[0096] The handle reset member makes the handle control end 521 of the handle body 520 always have a tendency to reset to the handle rotating seat 510, so that the handle body 520 can be automatically retracted when not in use, thus avoiding the handle body 520 protruding and colliding with other sashes 200 or hindering the normal movement of the sashes 200.

[0097] In order to make it more convenient for the user to operate, in this embodiment, the number of handle assemblies 500 on each sash 200 is set to two, and the two handle assemblies 500 are respectively arranged at the left and right ends of the sash 200. And in order to enable the other handle assembly 500 to move synchronously smoothly when one handle assembly 500 is operated, the handle receiving groove 250 is provided with a ramp structure so that the handle body 520 will automatically disengage from the handle receiving groove 250 when rotating.

[0098] Refer to Figure 4 、 Figure 7 The transmission assembly includes a first transmission gear 410, a first transmission rack 420, a transmission rod 430, and a steering transmission member 440.

[0099] The first transmission gear 410 is fixedly connected to the handle rotating seat 510 of the handle assembly 500, so that when the handle rotating seat 510 rotates, the first transmission gear 410 rotates with the handle assembly 500.

[0100] The first driving rack 420 extends in the up and down direction. The first driving rack 420 is slidably connected to the window sash 200 and meshes with the first driving gear 410. When the first driving gear 410 rotates, it drives the first driving rack 420 to move up and down.

[0101] The number of transmission rods 430 is set to four. The four transmission rods 430 are respectively arranged on the four sides of the window sash 200. The transmission rod 430 is a straight rod-shaped member and is slidably connected to the window sash 200. One of the transmission rods 430 is fixedly connected to the first driving rack 420 so that this transmission rod 430 can move up and down with the first driving rack 420.

[0102] The number of steering transmission members 440 is also set to four. The four steering transmission members 440 are respectively fixedly arranged at the four corners of the window sash 200. The steering transmission member 440 is a conventional door and window accessory, and the specific structure of the steering transmission member 440 will not be elaborated here. Connection points are respectively provided at both ends of the steering transmission member 440, and the connection points are connected to the two adjacent transmission rods 430.

[0103] By setting the steering transmission member 440, this corner transmission member can realize the conversion of the torque between the horizontal direction and the vertical direction, so as to realize the power transmission between multiple transmission rods 430, so that multiple transmission rods 430 can move synchronously. At the same time, the modular design of the steering transmission member 440 is convenient for maintenance and replacement, improving the long-term reliability of the broken bridge sliding window.

[0104] During actual use, the transmission rods 430 on the left and right sides of the window sash 200 move in opposite directions (that is, one of the transmission rods 430 moves upward and the other transmission rod 430 moves downward), and the transmission rods 430 on the upper and lower sides of the window sash 200 also move in opposite directions.

[0105] Refer to Figure 8 、 Figure 9 , the side sealing structure includes two sealing and locking components, which are respectively set as a locking point component and a locking seat component. The locking point component is installed at the locking point end of the window sash 200, and the locking seat component is installed at the locking seat end of the window sash 200.

[0106] Specifically, the sealing and locking component includes a driving seat 311, a locking member, a locking reset member 313, a locking linkage rod 314, a connecting driving member 315, and a side sealing strip 316.

[0107] The sealing and locking component has a normal state and a locking state.

[0108] The driving seat 311, the locking member, the locking reset member 313, and the locking linkage rod 314 form a locking linkage structure.

[0109] The driving seat 311 is installed inside the window sash 200. The driving seat 311 is slidably connected to the window sash 200, and the driving seat 311 can slide up and down relative to the window sash 200. The driving seat 311 is fixedly connected to the transmission rod 430. When the transmission rod 430 moves up and down, the driving seat 311 will move up and down with the transmission rod 430.

[0110] The locking member protrudes from the side sealing end face. The locking member is installed on the driving seat 311. The locking member is slidably connected to the driving seat 311, and the locking member can slide up and down relative to the driving seat 311 along the up and down direction.

[0111] In the case of not being affected by other external forces, the locking member will move up and down with the driving seat 311 or be aligned with the driving seat 311 and the two are relatively stationary. At this time, the sealing and locking assembly is in a normal state, and the relative positions of the locking member and the driving seat 311 will not change.

[0112] The locking member of the locking seat assembly is set as the sealing locking seat 3121, and the locking member of the locking point assembly is set as the sealing locking point 3122.

[0113] Since the moving directions of the transmission rods 430 on the left and right sides of the window sash 200 are opposite, the moving directions of the locking members of the two sealing and locking assemblies are also opposite, so that the moving directions of the sealing locking seat 3121 and the sealing locking point 3122 in the same window sash 200 are opposite.

[0114] When the driving seat 311 moves, if the sealing locking seat 3121 is locked with the sealing locking point 3122 of the adjacent window sash 200, the movement of the locking member along the up and down direction is blocked. The locking member will move up and down relative to the driving seat 311, causing the locking member and the driving seat 311 to be misaligned, and the relative positions of the locking member and the driving seat 311 change. At this time, the sealing and locking assembly is in the locking state.

[0115] The locking and resetting member 313 is arranged between the driving seat 311 and the locking member. Specifically, in this embodiment, the locking and resetting member 313 is set as a spring. The driving seat 311 is provided with a resetting member installation groove. The locking and resetting member 313 is arranged in the resetting member installation groove. The locking member is provided with a resetting abutting plate. The resetting abutting plate is arranged in the resetting member installation groove, and the resetting abutting plate is slidably connected to the resetting member installation groove along the up and down direction. The two ends of the locking and resetting member 313 are respectively abutted against the resetting abutting plate and the inner wall of the resetting member installation groove. When the locking member moves up and down relative to the driving seat 311, the locking and resetting member 313 is compressed, and the locking and resetting member 313 stores elastic potential energy. When the external force acting on the locking member disappears, the locking and resetting member 313 drives the locking member to move, driving the locking member to reset from the locking state to the normal state, so that the locking member is reset to be aligned with the driving seat 311.

[0116] In other embodiments, the locking and resetting member 313 may also be set as a resilient block or a spring piece, etc. Those skilled in the art can select the specific structure of the locking and resetting member 313 according to actual needs.

[0117] The number of locking linkage rods 314 in each locking linkage structure is set to two. The two ends of the locking linkage rod 314 are respectively set as a first hinged end and a second hinged end. The first hinged end of one locking linkage rod 314 is hinged to the driving seat 311, and the first hinged end of the other locking linkage rod 314 is hinged to the locking member. The second hinged ends of the two locking linkage rods 314 are hinged to each other.

[0118] When the locking member moves relative to the driving seat 311, since the length of the locking linkage rod 314 is fixed, the angle between the two locking linkage rods 314 will change, so that the second hinged end swings around the hinge axis of the locking linkage rod 314 and the driving seat 311, so that the second hinged end moves in the left - right direction and the up - down direction.

[0119] The connecting driving member 315 is arranged in the window sash 200. The connecting driving member 315 extends in the up - down direction. The connecting driving member 315 is slidably connected to the window sash 200, and the connecting driving member 315 can move relative to the window sash 200 in the left - right direction. The connecting driving member 315 is hinged to the second hinged ends of the two locking linkage rods 314. When the second hinged end moves in the left - right direction, the connecting driving member 315 will move in the left - right direction along with the second hinged end. When the second hinged end moves in the up - down direction, the connecting driving member 315 will also move in the up - down direction along with the second hinged end.

[0120] The side sealing strip 316 is slidably connected to the connecting driving member 315, and the side sealing strip 316 can slide relative to the connecting driving member 315 in the up - down direction. The side sealing strip 316 can extend out or retract into the side sealing plane. The side sealing strip 316 is used to abut against the side sealing plane of another window sash 200, so as to realize the sealing between two adjacent window sashes 200.

[0121] Specifically, the side sealing strips 316 of two adjacent window sashes 200 are arranged in a staggered manner, so that the sealing performance between two adjacent window sashes 200 is better. In other embodiments, the positions of the side sealing strips 316 of two adjacent window sashes 200 can also be arranged corresponding to each other. Those skilled in the art can select the specific positions of the side sealing strips 316 of two adjacent window sashes 200 according to actual needs.

[0122] Specifically, in this embodiment, the number of side sealing strips 316 in each sealing and locking assembly is set to two. The two side sealing strips 316 are respectively arranged on the first sash 210 and the second sash 230, and the two side sealing strips 316 are fixed by a plurality of sealing connecting rods (the sealing connecting rods are not shown in the figure).

[0123] The first sash body 210, the sash bridge 220, and the second sash body 230 are all provided with connecting rod sliding grooves (the connecting rod sliding grooves are not shown in the figure). The sealing strip connecting rod passes through the connecting rod sliding grooves of the first sash body 210, the sash bridge 220, and the second sash body 230, and the sealing strip connecting rod is slidably connected with the connecting rod sliding grooves in the left - right direction.

[0124] By arranging a plurality of sealing connecting rods to connect the two side sealing strips 316, the two side sealing strips 316 can move synchronously in the left - right direction.

[0125] Since the locking linkage rod 314 will additionally drive the connecting driving member 315 to move up and down during movement, and the side sealing strip 316 only needs to move in the left - right direction and does not need to move up and down. By arranging the connecting driving member 315 between the locking linkage rod 314 and the side sealing strip 316, and making the connecting driving member 315 slid along the up - down direction with the side sealing strip 316, the displacement of the side sealing strip 316 in the up - down direction can be effectively avoided.

[0126] During the process of the sealing and locking assembly being converted from the general state to the locking state, the two locking linkage rods 314 drive the side sealing strips 316 to extend out of the side sealing end face, so that the side sealing strips 316 are in contact with the side sealing end faces of the adjacent window sashes 200. Conversely, they are retracted into the side sealing end face.

[0127] Specifically, in this embodiment, the number of locking linkage structures in the same sealing and locking assembly is set to be multiple, and the multiple locking linkage structures are arranged at intervals in the up - down direction, so as to avoid the connecting driving member 315 from tilting during movement.

[0128] Refer to Figure 7 、 Figure 8 、 Figure 9 , assume that two adjacent window sashes 200 to be sealed and locked are the first window sash and the second window sash. The process of sealing and locking the first window sash and the second window sash is as follows:

[0129] The user first pulls the first window sash towards the interior of the room, so that the front end face of the first window sash is pressed tightly against the frame edge sealing strip 150 of the window frame 100. Subsequently, the user rotates the handle assembly 500 of the first window sash, rotates the handle assembly 500 by 90 degrees, so that the driving seat 311 and the sealing lock seat 3121 of the first window sash move downward to the specified position;

[0130] Subsequently, the user moves the second window sash to the side of the lock seat end of the first window sash, pulls the second window sash towards the interior of the room, makes the second window sash flush with the first window sash, and then rotates the handle assembly 500 of the second window sash, so that the driving seat 311 and the sealing lock point 3122 of the second window sash move upward.

[0131] During the upward movement of the sealing lock point 3122, it will first come into contact with the sealing lock seat 3121 of the first window sash. After contacting the sealing lock seat 3121, the sealing lock point 3122 of the second window sash and the driving seat 311 still need to continue moving upward for a certain distance to a specified position. During the continued upward movement of the sealing lock point 3122, the sealing lock point 3122 will be misaligned with the corresponding driving seat 311, and the sealing lock seat 3121 will also be misaligned with the corresponding driving seat 311. Both the sealing lock point 3122 and the sealing lock seat 3121 enter the locked state. At this time, since the sealing lock point 3122 and the sealing lock seat 3121 are misaligned relative to their respective corresponding driving seats 311, the two locking linkage rods 314 will drive the side sealing strip 316 to extend out of the side sealing end face, causing the side sealing strip 316 to abut against the side sealing end face of the adjacent window sash 200.

[0132] The handle assembly 500 of the second window sash can also be operated first, and then the handle assembly 500 of the first window sash can be operated. The action process of this operation method is similar to that of the above operation method, except for the movement sequence of the sealing lock point 3122 and the sealing lock seat 3121.

[0133] Refer to Figure 3 、 Figure 5 、 Figure 10 Between each window frame 100 and window sash 200, a frame-sash lock position assembly 600 is provided (that is, in this solution, the number of frame-sash lock position assemblies 600 is set to two). Specifically, the frame-sash lock position assembly 600 includes a frame-sash lock seat 610 and a frame-sash lock point 620.

[0134] The frame-sash lock seat 610 is fixedly arranged on the window frame 100. The frame-sash lock seat 610 is provided with a frame-sash lock position groove 611, and the notch of the frame-sash lock position groove 611 faces left or right. At the notch of the frame-sash lock position groove 611, there is a sealing push portion 612. The end face of the sealing push portion 612 is connected to the inner wall of the frame-sash lock position groove 611. The sealing push portion 612 is used to limit the position of the frame-sash lock point 620 and enable the frame-sash lock point 620 to smoothly enter the frame-sash lock position groove 611 during the left-right movement.

[0135] The number of frame-sash lock seats 610 in each frame-sash lock position assembly 600 is set to multiple. Specifically, in this embodiment, the number of frame-sash lock seats 610 in each frame-sash lock position assembly 600 is set to four. The four frame-sash lock seats 610 are evenly arranged at the upper and lower ends of the window frame 100, that is, the four frame-sash lock seats 610 are grouped in two, and the two groups of frame-sash lock seats 610 are respectively arranged at the upper and lower ends of the window frame 100. The orientations of the frame-sash lock position grooves 611 of the frame-sash lock seats 610 at the upper and lower ends of the window frame 100 are set in opposite directions.

[0136] The frame-sash lock point 620 is installed on the sash 200, and the frame-sash lock point 620 is slidably connected to the sash 200. The number of frame-sash lock points 620 in each frame-sash lock position assembly 600 is set to be multiple, and the frame-sash lock points 620 and the frame-sash lock seats 610 are arranged in one-to-one correspondence. When locking the sash 200, the frame-sash lock points 620 enter the frame-sash lock position groove 611 from the lock point entrance. After the frame-sash lock points 620 enter the frame-sash lock position groove 611, the frame-sash lock position groove 611 can limit the position of the frame-sash lock points 620 in the front-back direction. At the same time, the vertical movement groove 180 limits the position of the guide ball 240 in the left-right direction, so as to limit the position of the sash 200.

[0137] The frame-sash lock point 620 is connected to the transmission rod 430 of the transmission assembly through the lock point linkage 640. Specifically, both ends of the lock point linkage 640 are respectively hinged to the frame-sash lock point 620 and the transmission rod 430, so that the frame-sash lock point 620 can move back and forth and left and right relative to the transmission rod 430.

[0138] The sash 200 is provided with a lock point guide groove 630. The lock point guide groove 630 is provided with a second guide groove 632 and a first guide groove 631. The second guide groove 632 and the first guide groove 631 are communicated with each other. The first guide groove 631 is arranged on the side of the second guide groove 632 away from the frame-sash lock seat 610. In this embodiment, the second guide groove 632 extends in the left-right direction.

[0139] The frame-sash lock point 620 passes through the lock point guide groove 630, and the frame-sash lock point 620 slides along the lock point guide groove 630. When the frame-sash lock point 620 moves along the first guide groove 631, the frame-sash lock point 620 approaches or moves away from the frame-sash lock seat 610 in the front-back direction; when the frame-sash lock point 620 moves along the second guide groove 632, the frame-sash lock point 620 enters or disengages from the frame-sash lock position groove 611 in the left-right direction.

[0140] The second guide groove 632 is arranged corresponding to the frame-sash lock position groove 611, and the second guide groove 632 extends in the left-right direction. By providing the first guide groove 631 and the second guide groove 632, in the non-locked state, the frame-sash lock points 620 are located in the first guide groove 631, and the frame-sash lock points 620 and the frame-sash lock seats 610 are arranged in a dislocation manner. The frame-sash lock seats 610 and the frame-sash lock points 620 will not interfere with the left-right movement of the sash 200, so as to ensure the normal operation of the basic functions of the broken bridge sliding window.

[0141] During the movement of the sash and frame locking point 620 along the first guiding groove 631, when the sash and frame locking point 620 contacts the sealing pushing part 612, the position of the sash and frame locking point 620 is restricted by the sealing pushing part 612, and the sash and frame locking point 620 cannot continue to move further in the front-back direction. At this time, since the transmission system is still working, the transmission rod 430 will continue to move, causing the locking point linkage 640 to swing around its hinge position with the sash and frame locking point 620, thereby pushing the transmission assembly and the window sash 200 closer to the frame edge sealing strip 150, making the window sash 200 and the window frame 100 sealed, so as to improve the sealing performance of this broken bridge sliding window, and thus improve the heat insulation and sound insulation performance.

[0142] When the window sash 200 and the window frame 100 are in a locked state, the sash and frame locking point 620 is arranged in the second guiding groove 632, and the sash and frame locking point 620 is inserted into the sash and frame locking position groove 611 and locked with the sash and frame locking seat 610, so that the window sash 200 cannot move back and forth relative to the window frame 100, thereby ensuring the locking of the window sash 200 and the window frame 100.

[0143] In order to prevent the sash and frame locking seat 610 from obstructing the window sash 200 when the window sash 200 moves in the second direction, in this embodiment, the first guiding groove 631 is inclined relative to the second guiding groove 632, so that when the sash and frame locking point 620 is located in the first guiding groove 631, the sash and frame locking point 620 and the sash and frame locking seat 610 are misaligned in the first direction, thereby preventing the sash and frame locking seat 610 from obstructing the movement of the window sash 200 in the second direction, so that the window sash 200 can move smoothly in the second direction.

[0144] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
