Abstract
Description
Technical Field
[0001] The invention relates to a door and window, in particular to a high-sealing sliding window. Background Art
[0002] A sliding window is a window that uses tracks and slide rails to allow the window sash to slide horizontally or vertically on the window frame. When the window sash is pushed or pulled horizontally, it is suitable to set track grooves above and below the frame. Since the window sash needs to slide, a gap needs to be retained between the window sash and the frame to reduce the friction generated when the window sash slides. This results in poor sealing between the window sash and the frame, and indoor and outdoor air can easily convect through the gap. Therefore, a sliding window with better sealing is urgently needed. Summary of the invention
[0003] The purpose of the present invention is to provide a high-sealing sliding window 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 sash is connected to the outer frame in a sliding manner along the left and right directions, an upper sealing groove is provided on the top side of the window sash, an upper fixing plate is connected to the bottom of the upper sealing groove, a lower sealing groove is provided on the bottom side of the window sash, and a lower fixing plate is connected to the bottom of the lower sealing groove; a pressing mechanism comprises a transmission part, an upper pressing part and a lower pressing part, the transmission part is arranged on one side of the inner part of the outer frame, the upper pressing part is arranged on the inner top side of the outer frame, an upper pressing plate is provided in the upper pressing part for rotating along an axis line in the left and right directions, the lower pressing part is arranged on the inner bottom side of the outer frame, and a lower pressing plate is provided in the lower pressing part for rotating along an axis line in the left and right directions, the upper pressing part and the lower pressing part are respectively connected to the transmission part in transmission, the transmission part can drive the upper pressing plate to rotate close to or away from the upper fixing plate, and the transmission part can drive the lower pressing plate to rotate close to or away from the lower fixing plate.
[0006] This technical solution has at least the following beneficial effects: when the window sash can slide normally in the left and right directions within the outer frame, the transmission part drives the upper pressure plate and the lower pressure plate to rotate away from the upper fixed plate and the lower fixed plate respectively. At this time, there is a gap between the two, and the window sash can slide smoothly left and right in the outer frame; when the window sash moves to one side of the outer frame to close the window, the transmission part can drive the upper pressure plate and the lower pressure plate to rotate close to the upper fixed plate and the lower fixed plate respectively. At this time, the upper pressure plate and the upper fixed plate are abutted against each other, and the lower pressure plate and the lower fixed plate are abutted against each other, thereby reducing the gap between the outer frame and the window sash. At this time, the air convection between indoor and outdoor can be effectively reduced, and the sealing of the entire sliding window can be improved. In addition, the upper pressure plate and the lower pressure plate are used to be close to the upper fixed plate and the lower fixed plate on the top side of the window sash, so as to enhance the stability of the window sash, which is particularly suitable for environments with high wind pressure.
[0007] As a further improvement of the above technical solution, the upper pressure part includes an upper shell, an upper transmission rod and an upper elastic member, the upper shell is connected to the top side of the inner side of the outer frame, the upper transmission rod is slidably connected to the upper shell in the left and right directions, a plurality of upper shift blocks are arranged at intervals in the left and right directions on the side of the upper transmission rod facing the upper pressure plate, the middle part of the upper pressure plate is rotatably connected to the upper shell along the axis in the left and right directions, and upper notches are respectively arranged at the positions of the upper pressure plate facing the plurality of upper shift blocks, the upper elastic member is connected to the upper pressure plate and the inner side of the upper shell, the upper elastic member has a tendency to press the top of the upper pressure plate toward the upper transmission rod, and the bottom of the upper pressure plate passes through the upper shell downward, the upper transmission rod is transmission-connected to the transmission part, the upper transmission rod can slide until the plurality of upper shift blocks are against the top of the upper pressure plate and the upper pressure plate rotates close to the upper fixed plate, or the upper transmission rod can slide until the plurality of upper shift blocks respectively enter the plurality of upper notches and the upper pressure plate rotates away from the upper fixed plate. When the window sash can slide normally in the left and right directions in the outer frame, the multiple upper notches on the upper pressure plate are directly opposite to the multiple upper shift blocks of the upper transmission rod. Under the elastic pressure of the upper elastic member, the upper pressure plate is pressed against the upper transmission rod, so that the upper pressure plate rotates away from the upper fixed plate. At this time, there is a gap between the upper pressure plate and the upper fixed plate, which does not affect the sliding of the window sash in the outer frame. When the window sash is closing and needs to be locked, the upper transmission rod is slid so that the multiple upper shift blocks and the multiple upper notches on the outside of the upper transmission rod are respectively staggered with each other and abut against the upper pressure plate. At this time, the top of the upper pressure plate can be pushed away from the upper transmission rod, the upper elastic member is elastically compressed, and the bottom of the upper pressure plate rotates close to the upper fixed plate, thereby stabilizing the position of the top side of the window sash and effectively reducing the gap between the top side of the window sash and the outer frame.
[0008] As a further improvement of the above technical solution, there are two upper pressing plates and two upper fixing plates respectively. The two upper pressing plates are respectively located on the front and rear sides of the upper transmission rod. The two upper fixing plates are connected to the bottom of the upper sealing groove at intervals in the front-rear direction, and the two upper fixing plates extend upward in a direction away from each other. When the window sash can slide within the outer frame, a plurality of upper notches on the two upper pressing plates are respectively aligned with the upper lifting blocks on both sides of the upper transmission rod. When the window sash is closed and needs to be locked, the upper transmission rod is slid, so that the upper lifting blocks on both sides of the upper transmission rod respectively press against the tops of the upper pressing plates on both sides, thereby driving the bottoms of the two upper pressing plates to rotate and approach the two upper fixing plates, so as to form two layers of seals in the front-rear direction between the top side of the window sash and the outer frame, further improving the sealing performance between the top side of the window sash and the outer frame.
[0009] As a further improvement of the above technical solution, a first rubber strip groove is provided at the position where the bottom of the upper pressing plate faces the upper fixing plate, and a first rubber strip is inserted into the upper pressing plate. When the bottom of the upper pressing plate rotates and approaches the upper fixing plate, the first rubber strip abuts against the upper pressing plate, which can effectively block the gap between the upper pressing plate and the upper fixing plate, further improving the sealing performance between the top side of the window sash and the outer frame.
[0010] As a further improvement of the above technical solution, a first sealing groove is provided at the position where the upper pressing plate faces the first rubber strip. When the bottom of the upper pressing plate rotates and approaches the upper fixing plate, the first rubber strip is pressed into the first rubber strip groove, and the upper pressing plate can also be closer to the upper fixing plate, so as to further improve the sealing performance between the top side of the window sash and the outer frame.
[0011] As a further improvement of the above technical solution, the transmission part includes a side housing, an upper swing rod, a first sliding rod, a second sliding rod and a side pressing block. The side housing is connected to the inner side of the outer frame. The side pressing block is slidably connected to the middle of the side housing in the left-right direction. A side elastic member is connected between the side of the side pressing block away from the window sash and the inner side of the side housing. The upper swing rod is rotatably connected to the inside of the side housing along the axis in the front-back direction. The first sliding rod is slidably connected to the top of the upper swing rod along the length direction of the upper swing rod. The top end of the first sliding rod is rotatably connected to one end of the upper transmission rod along the axis in the front-back direction. The second sliding rod is slidably connected to the bottom of the upper swing rod along the length direction of the upper swing rod. The bottom end of the second sliding rod is rotatably connected to the top end of the side pressing block. When the window sash is not locked, the side elastic member presses the side pressing block towards the side close to the window sash. When it is necessary to lock the window sash, the side pressing block is pressed into the side housing. At this time, the side elastic member is compressed. The side pressing block drives the upper swing rod to rotate through the second sliding rod, so that the top of the upper swing rod drives the upper transmission rod to press into the central position of the outer frame through the first sliding rod, thereby driving the upper pressing plate to rotate by using the upper transmission rod. When the pressure on the side pressing block is removed, the side elastic member pushes the side pressing block towards the side close to the window sash to reset, driving the upper swing rod to rotate in the reverse direction, so that the upper transmission rod resets in the direction away from the central position of the outer frame.
[0012] As a further improvement of the above technical solution, the position where the upper swing rod is rotatably connected to the side housing is located at the top of the upper swing rod. At this time, the distance between the rotation connection point of the upper swing rod and the side pressing block is longer, forming a longer force arm, while the distance between the rotation connection point of the upper swing rod and the upper transmission rod is shorter, forming a shorter force arm. At this time, when driving the upper swing rod to rotate through the side pressing block, less force is applied, and it is more labor-saving to drive the upper transmission rod to rotate.
[0013] As a further improvement of the above technical solution, a lock catch is arranged at intervals on the side of the side housing close to the side pressing block. A side pressing gap is formed between the lock catch and the side pressing block. A lock hook is slidably connected to the side of the window sash close to the side housing in the up-down direction. A guiding inclined surface is arranged on the side of the lock hook close to the side housing. The guiding inclined surface extends upward towards the direction close to the side housing. The lock hook can be inserted downward into the side pressing gap or withdrawn upward from the side pressing gap. When the window sash approaches the side of the outer frame, the window sash blocks the window position. At this time, sliding the lock hook downward can drive the lock hook to insert into the side pressing gap. Since the lock hook has an inclined guiding inclined surface, by using the guiding inclined surface to abut against the side pressing block, the side pressing block can be pressed away from the window sash, thereby pressing the side pressing block and driving the upper transmission rod to slide. In this way, while the window sash and the outer frame are locked to each other, the side pressing block can be driven to move.
[0014] As a further improvement of the above technical solution, two limiting plates are arranged at intervals along the front-back direction on the inner top side of the outer frame, and the two limiting plates are respectively inserted into the top side of the window sash. The two limiting plates can limit the top position of the window sash, effectively prevent the window sash from shaking, and improve the stability of the window sash movement.
[0015] As a further improvement of the above technical solution, two pulleys are arranged at intervals along the front-back direction on the bottom side of the window sash, and the two pulleys are respectively located on the front and back sides of the pressing part. The window sash can slide on the inner bottom side of the outer frame through the two pulleys on its bottom side. When it is necessary to lock the position of the window sash, the pressing part locks the window sash from the middle position of the bottom side of the window sash, improving the stability when the window sash slides and the position is locked.

Detailed implementation manners
[0024] 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 accompanying drawings 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 relationships mentioned in the text do not refer only to the direct connection of components, 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.
[0025] Referring to Figures 1 to 3 , a highly sealed sliding window, comprising: an outer frame 1; a window sash 2, which is slidably connected in the outer frame 1 in the left - right direction, an upper sealing groove 21 is arranged on the top side of the window sash 2, an upper fixing plate 22 is connected to the bottom of the upper sealing groove 21, a lower sealing groove is arranged on the bottom side of the window sash 2, and a lower fixing plate 23 is connected to the bottom of the lower sealing groove; a pressurizing mechanism, which comprises a transmission part 31, an upper pressing part and a lower pressing part, the transmission part 31 is arranged on one side inside the outer frame 1, the upper pressing part is arranged on the inner top side of the outer frame 1, an upper pressing plate 321 that rotates along the left - right axis is arranged inside the upper pressing part, the lower pressing part is arranged on the inner bottom side of the outer frame 1, a lower pressing plate 331 that rotates along the left - right axis is arranged inside the lower pressing part, the upper pressing part and the lower pressing part are respectively in transmission connection with the transmission part 31, the transmission part 31 can drive the upper pressing plate 321 to rotate close to or away from the upper fixing plate 22, and the transmission part 31 can drive the lower pressing plate 331 to rotate close to or away from the lower fixing plate 23.
[0026] In this highly airtight sliding window, when the window sash 2 can slide normally in the left-right direction within the outer frame 1, the transmission part 31 drives the upper pressing plate 321 and the lower pressing plate 331 to rotate away from the upper fixing plate 22 and the lower fixing plate 23 respectively. At this time, there is a gap between them, and the window sash 2 can slide smoothly in the left-right direction within the outer frame 1. When the window sash 2 moves to one side of the outer frame 1 to close the window opening, the transmission part 31 can drive the upper pressing plate 321 and the lower pressing plate 331 to rotate close to the upper fixing plate 22 and the lower fixing plate 23 respectively. At this time, the upper pressing plate 321 abuts against the upper fixing plate 22, and the lower pressing plate 331 abuts against the lower fixing plate 23, reducing the gap between the outer frame 1 and the window sash 2. At this time, the air convection between the indoor and outdoor can be effectively reduced, improving the airtightness of the entire sliding window. Moreover, by using the upper pressing plate 321 and the lower pressing plate 331 to approach the upper fixing plate 22 and the lower fixing plate 23 on the top side of the window sash 2, the stability of the window sash 2 can be enhanced, especially suitable for environments with relatively high wind pressure.
[0027] The upper pressing part forms a transmission structure that drives the upper pressing plate 321 to rotate. Specifically, the upper pressing part includes an upper shell body 322, an upper transmission rod 323 and an upper elastic member 324. The upper shell body 322 is connected to the top side of the outer frame 1. The upper transmission rod 323 is slidably connected to the upper shell body 322 along the left and right directions. A plurality of upper shifting blocks 3231 are arranged at intervals along the left and right directions on the side of the upper transmission rod 323 facing the upper pressing plate 321. The middle part of the upper pressing plate 321 is rotatably connected to the upper shell body 322 along the axis in the left and right directions. Upper notches are respectively arranged at the positions of the upper pressing plate 321 facing the plurality of upper shifting blocks 3231. The upper elastic member 324 is connected to the upper pressing plate 321 and the On the inner side of the upper shell body 322, the upper elastic member 324 has a tendency to press the top of the upper pressure plate 321 toward the upper transmission rod 323. The upper elastic member 324 can adopt an elastic structure such as a spring, a torsion spring, or rubber. The bottom of the upper pressure plate 321 passes downward through the upper shell body 322, and the upper transmission rod 323 is transmission-connected to the transmission part 31. The upper transmission rod 323 can slide until the multiple upper shifting blocks 3231 are against the top of the upper pressure plate 321 and the upper pressure plate 321 is rotated close to the upper fixed plate 22, or the upper transmission rod 323 can slide until the multiple upper shifting blocks 3231 respectively enter the multiple upper notches and the upper pressure plate 321 is rotated away from the upper fixed plate 22. When the window sash 2 can slide normally in the left and right directions in the outer frame 1, the multiple upper notches on the upper pressure plate 321 and the multiple upper shift blocks 3231 of the upper transmission rod 323 are opposite to each other, and under the elastic pressure of the upper elastic member 324, the upper pressure plate 321 is pressed to the upper transmission rod 323, so that the upper pressure plate 321 rotates away from the upper fixing plate 22. At this time, there is a gap between the upper pressure plate 321 and the upper fixing plate 22, which does not affect the sliding of the window sash 2 in the outer frame 1. When the window sash 2 is closed and needs to be locked, the upper transmission rod 323 is slid, so that the multiple upper shift blocks 3231 on the outer sides of the upper transmission rod 323 are staggered with the multiple upper notches respectively and abut against the upper pressure plate 321. At this time, the top of the upper pressure plate 321 can be pushed away from the upper transmission rod 323, the upper elastic member 324 is elastically compressed, and the bottom of the upper pressure plate 321 rotates close to the upper fixing plate 22, thereby stabilizing the position of the top side of the window sash 2 and effectively reducing the gap between the top side of the window sash 2 and the outer frame 1.
[0028] In order to further improve the sealing performance between the top side of the window sash 2 and the inner top side of the outer frame 1, in this embodiment, the number of the upper pressing plates 321 and the upper fixing plates 22 are both two. The two upper pressing plates 321 are respectively located on the front and rear sides of the upper transmission rod 323. The two upper fixing plates 22 are connected to the bottom of the upper sealing groove 21 at intervals in the front-rear direction, and the two upper fixing plates 22 extend upward in a direction away from each other. When the window sash 2 can slide within the outer frame 1, a plurality of upper notches of the two upper pressing plates 321 are respectively aligned with the upper lifting blocks 3231 on both sides of the upper transmission rod 323. When the window sash 2 is closed and needs to be locked, the upper transmission rod 323 is slid, so that the upper lifting blocks 3231 on both sides of the upper transmission rod 323 respectively press against the tops of the two upper pressing plates 321, thereby driving the bottoms of the two upper pressing plates 321 to rotate and approach the two upper fixing plates 22. In this way, two layers of seals are formed in the front-rear direction between the top side of the window sash 2 and the outer frame 1, further improving the sealing performance between the top side of the window sash 2 and the outer frame 1.
[0029] In some embodiments, a first rubber strip 325 groove is provided at a position where the bottom of the upper pressing plate 321 faces the upper fixing plate 22, and a first rubber strip 325 is inserted into the upper pressing plate 321. When the bottom of the upper pressing plate 321 rotates and approaches the upper fixing plate 22, by using the first rubber strip 325 to abut against the upper pressing plate 321, the gap between the upper pressing plate 321 and the upper fixing plate 22 can be effectively blocked, further improving the sealing performance between the top side of the window sash 2 and the outer frame 1.
[0030] Furthermore, a first sealing groove 326 is provided at a position where the upper pressing plate 321 faces the first rubber strip 325. When the bottom of the upper pressing plate 321 rotates and approaches the upper fixing plate 22, the first rubber strip 325 is pressed into the first rubber strip 325 groove, and the upper pressing plate 321 can also be closer to the upper fixing plate 22. In this way, the sealing performance between the top side of the window sash 2 and the outer frame 1 can be further improved.
[0031] The transmission part 31 is mainly used to convert the force applied and acting on the side of the outer frame 1 into the force driving the upper transmission rod 323 to slide left and right. Specifically, such as Figures 4 to 6, the transmission part 31 includes a side housing 311, an upper swing rod 312, a first sliding rod 313, a second sliding rod 314 and a side pressing block 315. The side housing 311 is connected to the inner side of the outer frame 1. The side pressing block 315 is slidably connected to the middle of the side housing 311 in the left-right direction. A side elastic member 318 is connected between the side of the side pressing block 315 away from the window sash 2 and the inner side of the side housing 311. The side elastic member 318 can be an elastic structure such as a spring or rubber. The upper swing rod 312 is rotatably connected to the inside of the side housing 311 along the axis in the front-rear direction. The first sliding rod 313 is slidably connected to the top of the upper swing rod 312 along the length direction of the upper swing rod 312. The top end of the first sliding rod 313 is rotatably connected to one end of the upper transmission rod 323 along the axis in the front-rear direction. The second sliding rod 314 is slidably connected to the bottom of the upper swing rod 312 along the length direction of the upper swing rod 312. The bottom end of the second sliding rod 314 is rotatably connected to the top end of the side pressing block 315. When the window sash 2 is not locked, the side elastic member 318 presses the side pressing block 315 towards the side close to the window sash 2. When it is necessary to lock the window sash 2, the side pressing block 315 is pressed into the side housing 311. At this time, the side elastic member 318 is compressed. The side pressing block 315 drives the upper swing rod 312 to rotate through the second sliding rod 314, so that the top of the upper swing rod 312 drives the upper transmission rod 323 to be pressed into the central position of the outer frame 1 through the first sliding rod 313, thereby driving the upper pressing plate 321 to rotate by using the upper transmission rod 323. When the pressure on the side pressing block 315 is removed, the side elastic member 318 pushes the side pressing block 315 towards the side close to the window sash 2 to reset, driving the upper swing rod 312 to rotate in the reverse direction, so that the upper transmission rod 323 resets in the direction away from the center of the outer frame 1.
[0032] In order to drive the upper swing rod 312 to rotate more labor-saving, in this embodiment, the position where the upper swing rod 312 is rotatably connected to the side housing 311 is located at the top of the upper swing rod 312. At this time, the distance between the rotation connection point of the upper swing rod 312 and the side pressing block 315 is longer, forming a longer force arm, while the distance between the rotation connection point of the upper swing rod 312 and the upper transmission rod 323 is shorter, forming a shorter force arm. At this time, when driving the upper swing rod 312 to rotate through the side pressing block 315, less force is applied, and it is more labor-saving to drive the upper transmission rod 323 to rotate.
[0033] For the drive of the side pressing block 315, a driving member such as a cylinder or a motor screw rod can be directly arranged in the side housing 311 to drive the side pressing block 315 to move. In this embodiment, a latch 316 is arranged at intervals on the side of the side housing 311 close to the side pressing block 315. A side pressing gap 317 is formed between the latch 316 and the side pressing block 315. A locking hook 24 is slidably connected in the up and down direction on the side of the window sash 2 close to the side housing 311. A guiding inclined surface is arranged on the side of the locking hook 24 close to the side housing 311. The guiding inclined surface extends upward in the direction close to the side housing 311. The locking hook 24 can be inserted downward into the side pressing gap 317 or withdrawn upward from the side pressing gap 317. When the window sash 2 approaches the side of the outer frame 1, the window sash 2 blocks the window position. At this time, sliding the locking hook 24 downward can drive the locking hook 24 to be inserted into the side pressing gap 317. Since the locking hook 24 has an inclined guiding inclined surface, by using the guiding inclined surface to abut against the side pressing block 315, the side pressing block 315 can be pressed away from the window sash 2, thereby pressing the side pressing block 315 and driving the upper transmission rod 323 to slide. In this way, while the window sash 2 and the outer frame 1 are locked to each other, the side pressing block 315 can be driven to move.
[0034] Similarly, for the lower pressing part, its structure is symmetrical with that of the upper pressing part. Specifically, the lower pressing part includes a lower shell, a lower transmission rod and a lower elastic member. The lower shell is connected to the inner bottom side of the lower frame, and the lower transmission rod is slidably connected to the lower shell along the left and right directions. A plurality of lower shifting blocks are arranged at intervals along the left and right directions on the side of the lower transmission rod facing the lower pressing plate 331. The middle part of the lower pressing plate 331 is rotatably connected to the lower shell along the axis in the left and right directions. Lower notches are respectively arranged at the positions of the lower pressing plate 331 facing the plurality of lower shifting blocks. The lower elastic member is connected to the lower pressing plate 331 and the On the inner side of the lower shell body, the lower elastic member has a tendency to press the bottom of the lower pressure plate 331 toward the lower transmission rod. The lower elastic member can adopt an elastic structure such as a spring, a torsion spring, or rubber. The top of the lower pressure plate 331 passes downward through the upper shell body 322, and the lower transmission rod is transmission-connected to the transmission part 31. The lower transmission rod can slide until the multiple lower shifting blocks are against the bottom of the lower pressure plate 331 and the lower pressure plate 331 is rotated close to the lower fixed plate 23, or the lower transmission rod can slide until the multiple lower shifting blocks respectively enter the multiple lower notches and the lower pressure plate 331 is rotated away from the lower fixed plate 23. When the window sash 2 can slide normally in the left and right directions in the outer frame 1, the multiple lower notches under the lower pressure plate 331 are opposite to the multiple lower shifting blocks of the lower transmission rod. Under the elastic pressure of the lower elastic member, the lower pressure plate 331 is pressed down to the lower transmission rod, so that the lower pressure plate 331 rotates away from the lower fixing plate 23. At this time, there is a gap between the lower pressure plate 331 and the lower fixing plate 23, which does not affect the sliding of the window sash 2 in the outer frame 1. When the window sash 2 is closed and needs to be locked, the lower transmission rod is slid so that the multiple lower shifting blocks on the outer side of the lower transmission rod are respectively staggered with the multiple lower notches and abut against the lower pressure plate 331. At this time, the bottom of the lower pressure plate 331 can be pushed away from the lower transmission rod, the lower elastic member is elastically compressed, and the top of the lower pressure plate 331 rotates close to the lower fixing plate 23, thereby stabilizing the position of the bottom side of the window sash 2 and effectively reducing the gap between the bottom side of the window sash 2 and the outer frame 1.
[0035] For the transmission of the lower transmission rod by the transmission part 31, similarly, the transmission part 31 further includes a lower swing rod, a third sliding rod and a fourth sliding rod. The side housing 311 is connected to the inner side of the outer frame 1. The side pressing block 315 is slidably connected to the middle of the side housing 311 in the left-right direction. A side elastic member 318 is connected between the side of the side pressing block 315 away from the window sash 2 and the inner side of the side housing 311. The lower swing rod is rotatably connected to the inside of the side housing 311 along the axis in the front-back direction. The third sliding rod is slidably connected to the bottom of the lower swing rod along the length direction of the lower swing rod. The bottom end of the third sliding rod is rotatably connected to one end of the lower transmission rod along the axis in the front-back direction. The fourth sliding rod is slidably connected to the top of the lower swing rod along the length direction of the lower swing rod. The top end of the fourth sliding rod is rotatably connected to the bottom end of the side pressing block 315 along the axis in the front-back direction. When the window sash 2 is not locked, the side elastic member 318 presses the side pressing block 315 towards the side close to the window sash 2. When it is necessary to lock the window sash 2, the side pressing block 315 is pressed into the side housing 311. At this time, the side elastic member 318 is compressed. The side pressing block 315 drives the lower swing rod to rotate through the fourth sliding rod, so that the bottom of the lower swing rod drives the lower transmission rod to press into the central position of the outer frame 1 through the third sliding rod, thereby driving the lower pressing plate 331 to rotate by using the lower transmission rod. When the pressure on the side pressing block 315 is removed, the side elastic member 318 resets the bottom of the side pressing block 315 towards the side close to the window sash 2, driving the lower swing rod to rotate in the reverse direction, so that the lower transmission rod resets towards the direction away from the central position of the outer frame 1.
[0036] In some embodiments, two limiting plates 11 are arranged at intervals in the front-back direction on the inner top side of the outer frame 1, and the two limiting plates 11 are respectively inserted into the top side of the window sash 2. The two limiting plates 11 can limit the top position of the window sash 2, effectively preventing the window sash 2 from shaking and improving the stability of the movement of the window sash 2.
[0037] In some embodiments, two pulleys 4 are arranged at intervals in the front-back direction on the bottom side of the window sash 2, and the two pulleys 4 are respectively located on the front and back sides of the lower pressing part. The window sash 2 can slide on the inner bottom side of the outer frame 1 through the two pulleys 4 on its bottom side. When it is necessary to lock the position of the window sash 2, the lower pressing part locks the window sash 2 from the middle position of the bottom side of the window sash 2, improving the stability of the window sash 2 during sliding and position locking.
