Description

Technical Field

[0001] The invention relates to the technical field of translational sliding windows, and in particular to a sliding window assembly which is both inward-tilting, airtight and translational. Background Art

[0002] Our company has previously developed a tilting, airtight and displacement systemized component for a sliding window, namely a patent for a multifunctional sliding window with publication number CN221169261U. The tilting, airtight and displacement systemized component of the prior art relies on the action linkage motion part of the handle part to act on the first sliding part, but the first sliding part has poor stability in use.

[0003] The specific reason is that if the first guide block (key) is to be disengaged or adapted to slide (inwardly tilted state or merged state) after displacement, the transmission bar (lock) of the first sliding part has higher rigidity requirements, and the transmission bar needs to be provided with multiple undulations; in addition, a first guide opening needs to be opened on the transmission bar, and the first guide opening must be provided in the undulating section of the transmission bar, and the first guide opening is a combination of an oblique opening and a straight opening. Then, the movement of the first guide block at the first guide opening on the transmission bar will lead to a deviation in continuity due to the poor adaptability of the undulating section and the oblique and straight openings, thereby affecting the stability of the inward tilting, airtightness and displacement actions of the sliding window. Summary of the invention

[0004] The present invention provides a sliding window assembly that is both inward-tilting, airtight and translatable, which solves the problem that the inward-tilting, airtight and displacement systematized assembly of the translatable sliding window in the prior art has poor stability in use due to complicated structural design.

[0005] The technical solution of the present invention is achieved in this way:

[0006] A sliding window assembly capable of tilting, airtightness and translation, comprising a fixing part and a sliding part slidably arranged at the bottom thereof, wherein both sides of the top of the fixing part are provided with tilting linkage parts respectively, the ends of the tilting linkage parts are provided with guide wheels sliding along the top of the window frame, and the outside of the tilting linkage parts is provided with a limiting part which is self-locked or unlocked in accordance with the displacement of the sliding part;

[0007] The sliding member includes a sliding bar and guide bars connected at both ends thereof and slidingly arranged along the top of the glass sash, and a sliding key is arranged above the connecting end of the guide bar and the sliding bar;

[0008] The fixing member comprises a fixing seat fixed on the top of the glass sash and a sliding groove opened at the bottom of the fixing seat and adapted to slide with the sliding bar;

[0009] The inverted linkage member includes a connecting rod A with one end hinged to the top of the fixing seat, and the end of the connecting rod A away from the fixing seat is hinged to the guide wheel member;

[0010] The limiting member includes a locking block and a straight groove and an oblique groove at the bottom thereof adapted to the sliding key. A through hole adapted to the connecting rod A is provided in the locking block; the end of the oblique groove faces the interior of the room.

[0011] Furthermore, the straight groove is located close to one side of the guide wheel, and the inclined groove is connected to the straight groove, and the sliding key is slidably adapted along the straight groove and the inclined groove through the displacement of the guide bar.

[0012] Furthermore, the fixing seat is provided with two symmetrically arranged anti-slip grooves, in which an anti-slip shaft is movably connected, and the end of the connecting rod A away from the guide wheel member rotates and slides on the anti-slip groove by being fixed to the anti-slip shaft.

[0013] Furthermore, a connecting rod B is hinged on the connecting rod A, and one end of the connecting rod B away from the connecting rod A is hinged to the end of the fixed seat, and the connecting rod B is located on the side of the locking block away from the guide wheel member.

[0014] Furthermore, hinge grooves are respectively provided on both sides of the top of the fixing seat, and the connecting rod B is adapted to fit in the hinge grooves.

[0015] Furthermore, a plurality of nuts threadedly mounted with the glass sash are provided on the front and rear sides of the fixing seat.

[0016] Furthermore, an eccentric block is rotatably connected to the connecting rod A, and a U-shaped hole is provided on the side of the locking block away from the straight groove, and the eccentric block is adapted to fit in the U-shaped hole of the locking block.

[0017] Furthermore, the guide wheel component includes a positioning plate rotatably arranged at the bottom through a rotating shaft and the end of the connecting rod A, and a plurality of guide wheels are arranged on the top of the positioning plate.

[0018] Beneficial effects of the technical solution provided by this application:

[0019] 1. Compared with the prior art, the tilt-in, airtight and translational sliding window assembly has a fixed part and a tilt-in linkage part which are hingedly arranged, and then the height of the tilt-in linkage part is raised by the fixed part. There is no need to set a complex structure with multiple undulating sections on the connecting rod A, which can improve the consistency and stability of the cooperation between the sliding key and the tilt-in linkage part from the structural point of view.

[0020] 2. The tilt-in, airtight and translational sliding window assembly directly sets a limiter on the connecting rod A of the tilt-in linkage member. The straight groove and the oblique groove in the limiter are integrated with the limiter, that is, the straight groove and the oblique groove are on the same horizontal plane. The sliding action of the sliding key in the straight groove and the oblique groove can be fast and will not get stuck, overcoming the undulating, oblique mouth and other structures of the traditional design that cause the sliding key to have movement deviation and insufficient stability.

[0038] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1

[0040] Reference Figure 1-4 A sliding window assembly with inward tilt, airtightness and translation, comprising a fixing member 20 and a sliding member 10 slidably arranged at the bottom thereof, inward tilt linkage members 30 are respectively arranged on both sides of the top of the fixing member 20, and a guide wheel member 50 is arranged at the end of the inward tilt linkage member 30 to slide along the top of the window frame, and a limit member 40 is arranged on the outside of the inward tilt linkage member 30 to self-lock or unlock in accordance with the displacement of the sliding member 10; the sliding member 10 comprises a sliding bar 11 and guide bars 12 respectively connected at both ends thereof and slidably arranged along the top of the glass leaf, and a sliding key 13 is arranged above the connecting end of the guide bar 12 and the sliding bar 11; the fixing member 20 comprises a fixing seat 21 fixed at the top of the glass leaf and a sliding groove 22 opened at the bottom of the fixing seat 21 and slidably adapted to the sliding bar 11; the inward tilt linkage member 30 comprises a connecting rod A 31 hinged at one end to the top of the fixing seat 21, and the connecting rod A The end of the stopper 40 away from the fixing seat 21 is hinged to the guide wheel member 50; the limit member 40 includes a locking block 41 and a straight groove 42 and an oblique groove 43 opened at the bottom thereof and adapted to the sliding key 13, and a through hole 45 adapted to the connecting rod A 31 is opened in the locking block 41; the end of the oblique groove 43 faces the interior of the room.

[0041] The fixing member 20 is used as a fixed base of the sliding window assembly. The fixing member 20 is fixed to the top of the glass leaf through the fixing seat 21, providing a stable sliding path for the sliding member 10, ensuring the stability of the translation and inward tilting of the sliding window. The sliding member 10 includes a sliding bar 11 and a guide bar 12. The sliding bar 11 slides in the slide groove 22 of the fixing member 20 to transmit the action of the inward tilting, airtight or translation state. The guide bar 12 is connected to the sliding bar 11 to ensure the stability and accuracy of the action transmission. The inward tilting linkage member 30 is hinged with the fixing seat 21 and the guide wheel member 50 through the connecting rod A 31 to realize the linkage action when the sliding window is tilted inward. The rotation action of the inward tilting linkage member 30 causes the guide wheel member 50 to slide along the top of the window frame to realize the inward tilting. The guide wheel member 50 is installed at the end of the inward tilting linkage member 30, and the guide wheel member 50 slides on the top of the window frame to ensure the smooth movement of the sliding window when tilting inward, while reducing friction and wear. The stopper 40 includes a locking block 41, and a straight groove 42 and an inclined groove 43 are provided at the bottom thereof for cooperating with the sliding key 13. The stopper 40 provides locking or unlocking in different states of the sliding window, ensuring the safety of the sliding window and the convenience of operation. The end of the inclined groove 43 faces the indoor, which is convenient for the operator to achieve locking or unlocking by moving the sliding key 13. The sliding key 13 is located above the connecting end of the guide bar 12 and the sliding bar 11, and the sliding key 13 slides in the straight groove 42 and the inclined groove 43 of the stopper 40 to achieve locking and unlocking of the sliding window. The design of the sliding key 13 allows the user to control the state of the sliding window through simple operations. The sliding key 13 can be a shaft-like part or a wheel-like part. For example, the block key 13 is composed of a convex shaft and a bearing, and the convex shaft is fixed on the guide bar 12. This design allows the block key 13 to move stably on the guide bar 12, and the fixity of the convex shaft ensures the accuracy and reliability of the block key 13 when transmitting force. The convex shaft of the block key 13 is fixed on the guide bar 12, and the bearing is arranged on the convex shaft. Such a design makes the block key 13 move more smoothly in the lock block 41, and reduces the wear caused by direct contact. When the operator controls the state of the sliding window through the block key 13, the combination of the convex shaft and the bearing ensures the stability and low friction when the block key 13 slides in the straight groove 42 and the inclined groove 43 in the lock block 41.

[0042] The working principle of the above technical solution is summarized as follows. Figure 1 As a position reference, the guide wheel member 50 is facing the outdoor direction, and the sliding member 10 is facing the indoor direction. The guide wheel member 50 is set in the track groove at the top of the window frame, and the sliding member 10 and the fixing member 20 are set at the top of the glass sash, wherein the fixing member 20 is fixed at the top of the glass sash, and the sliding member 10 not only slides in the top track groove of the glass sash, but also slides in the bottom slide groove 22 of the fixing member 20, that is, the sliding member 10 slides between the glass sash and the fixing member 20. The inner tilt linkage member 30 is a key component connecting the fixing member 20 and the guide wheel member 50, that is, the inner tilt of the glass sash relies on the unfolding action of the inner tilt linkage member 30.

[0043] When the glass sash is in normal translation, the sliding key 13 on the sliding bar 11 is located in the straight groove 42 of the locking block 41. At this time, the locking block 41 is limited by the sliding key 13, that is, the inner tilting linkage 30 cannot rotate on the fixing member 20 because of the locking of the locking block 41 and the sliding key 13. Then, the operator cannot complete the inner tilting action by pulling the glass sash toward the indoor direction. At this time, the glass sash can only slide left and right on the window sash normally.

[0044] When it is necessary to isolate outside air from entering the room or to lock the glass sash on the window frame, the operator operates the handle to apply a pulling force to the guide strip 12 of the sliding member 10 (the specific movement of the handle on the lock box and the linkage movement are conventional operations and will not be described in detail here. Please refer to the utility model patent with application number 202421523925X and the utility model patent with publication number CN221169261U). The guide strip 12 pushes the sliding strip 11 to slide in the slide groove 22 of the fixed seat 21 and pushes the other guide strip 12 to slide at the same time. The guide strips 12 at both ends slide and drive the sliding key 13 to slide in the inclined groove 43 of the locking block 41. The lateral movement is converted into longitudinal movement through the cooperation of the inclined groove 43, thereby realizing the locking of the glass sash on the window frame.

[0045] Specifically, for example, the end of the straight groove 42 is assumed to be point A, and the end of the inclined groove 43 is point B. As mentioned above, the end of the inclined groove 43 faces indoors. Since the window frame is embedded in the wall and does not move, the guide wheel member 50 is adapted in the window frame and its relative position is also fixed. The position of the glass sash is determined based on the inner tilt linkage member 30, the sliding member 10 and the fixing member 20. When the sliding key 13 moves from point A to point B, the end of the inclined groove 43 is closer to the outdoors relative to its original position, that is, the entire glass sash is closer to the window frame and pressed to achieve locking or airtightness.

[0046] When the glass sash needs to be tilted inward, the operator reverses the handle to make the guide bar 12 move in the reverse direction to drive the sliding key 13 to disengage from the inclined groove 43 and the straight groove 42 of the lock block 41. At this time, the inward tilt linkage 30 can rotate on the fixing member 20 because the lock block 41 and the sliding key 13 are unlocked. Since the two ends of the inward tilt linkage 30 are respectively hinged to the fixing seat 21 and the guide wheel 50, the operator only needs to pull it in the pulling direction indoors to realize the expansion of the connecting rod A31, and the glass sash in this state completes the inward tilt action. In addition, the glass sash in the inward tilt state can also slide at any position on the window frame without any constraints.

[0047] In some embodiments, the straight groove 42 is located close to one side of the guide wheel 50, and the inclined groove 43 is interconnected with the straight groove 42, and the sliding key 13 slides and fits in the straight groove 42 and the inclined groove 43 through the displacement of the guide bar 12. The straight groove 42 is close to one side of the guide wheel 50. Such a design makes the position of the sliding key 13 in the straight groove 42 closer to the starting position of the inward tilting action of the sliding window, which is convenient for rapid conversion when inward tilting is required. The inclined groove 43 is interconnected with the straight groove 42, allowing the sliding key 13 to smoothly transition between the two grooves, thereby realizing the conversion from the inward tilting state to the locking or airtight state. The sliding key 13 slides in the straight groove 42 and the inclined groove 43 through the displacement of the guide bar 12. Such a design ensures that the sliding of the sliding key 13 in different grooves can be accurately transmitted to the inward tilting linkage 30 and the guide wheel 50, thereby realizing different functional states of the sliding window.

[0048] The sliding adaptability of the sliding key 13 is achieved by the displacement of the guide bar 12. It can slide in the straight groove 42 and the inclined groove 43 to adapt to the different functional requirements of the sliding window. The position of the straight groove 42 is close to one side of the guide wheel 50, which is conducive to the sliding key 13 to quickly align with the guide wheel 50 when it needs to be tilted inward, thereby triggering the tilting action. The design of the inclined groove 43 enables the sliding key 13 to lock the glass sash by sliding the inclined groove 43 when performing the locking or airtight action.

[0049] In some embodiments, the fixing seat 21 is provided with two symmetrically arranged anti-slip grooves 26, and an anti-slip shaft 25 is movably connected in the anti-slip groove 26. The end of the connecting rod A31 away from the guide wheel 50 is fixed to the anti-slip shaft 25 so as to rotate and slide on the anti-slip groove 26. The two symmetrically arranged anti-slip grooves 26 provided in the fixing seat 21 are used to ensure the stability of the connecting rod A31 during the rotation and sliding process, and prevent the connecting rod A31 from falling out of the fixing seat 21, thereby ensuring the safety and reliability of the sliding window assembly. The anti-slip shaft 25 movably connected in the anti-slip groove 26 is fixed to the end of the connecting rod A31 away from the guide wheel 50, allowing the connecting rod A31 to rotate and slide on the anti-slip groove 26, while limiting the movement range of the connecting rod A31, preventing it from excessive movement or falling out, and enhancing the stability of the entire system.

[0050] The two symmetrically arranged anti-slip grooves 26 in the fixing seat 21 and the movably connected anti-slip shaft 25 work together to provide a stable rotation and sliding platform for the connecting rod A 31. When the operator operates the sliding key 13 to achieve the inward tilt, airtight or translation state of the sliding window, the rotation and sliding of the connecting rod A 31 on the anti-slip groove 26 are restricted by the anti-slip shaft 25, ensuring that the movement of the connecting rod A 31 does not exceed the design range, thereby avoiding potential mechanical failure or damage.

[0051] In some embodiments, the connecting rod A31 is hinged with a connecting rod B32, and one end of the connecting rod B32 away from the connecting rod A31 is hinged with the end of the fixing seat 21, and the connecting rod B32 is located on the side of the locking block 41 away from the guide wheel member 50. The connecting rod B32 is hinged on the connecting rod A31, and this design allows the connecting rod A31 to achieve more precise and limited action angle control through the cooperation of the connecting rod B32 when performing the inverted action. The end of the connecting rod B32 away from the connecting rod A31 is hinged with the end of the fixing seat 21, which ensures the stability of the connecting rod B32 during the action, and at the same time limits the action range of the connecting rod A31 to prevent excessive rotation or movement. The connecting rod B 32 is located on the side of the locking block 41 away from the guide wheel member 50. Such a layout helps to establish an effective mechanical connection between the locking block 41 and the guide wheel member 50. At the same time, when the locking block 41 is locked or unlocked, the movement of the connecting rod A 31 is transmitted and restricted by the connecting rod B 32.

[0052] The hinged design of the connecting rod A 31 and the connecting rod B 32, as well as the hinged connection of the connecting rod B 32 and the fixing seat 21, together constitute a stable mechanical connection system. When the sliding key 13 slides in the straight groove 42 and the inclined groove 43 of the limiter 40, it not only directly affects the state of the locking block 41, but also accurately controls the action angle of the inner tilt linkage through the cooperation of the connecting rod A 31 and the connecting rod B 32. This design ensures that the conversion of the sliding window between the inner tilt, airtight and translation states is both accurate and safe. The existence of the connecting rod B 32 limits the action angle of the connecting rod A 31 and prevents excessive rotation, thereby protecting the mechanical structure of the entire sliding window assembly, extending its service life, and improving the stability and safety of operation.

[0053] In some embodiments, hinge grooves 24 are respectively provided on both sides of the top of the fixing seat 21, and the connecting rod B32 is adapted in the hinge grooves 24. The hinge grooves 24 provided on both sides of the top of the fixing seat 21 provide an adapted space for the connecting rod B32, allowing the connecting rod B32 to rotate therein, and such a design enhances the connection stability between the connecting rod B32 and the fixing seat 21. The connecting rod B32 can be adapted in the hinge grooves 24, which means that the connecting rod B32 can rotate freely in the hinge grooves 24 while maintaining the connection with the fixing seat 21, and such a design allows the connecting rod B32 to have higher flexibility and stability when transmitting actions.

[0054] The hinge slots 24 on both sides of the top of the fixing seat 21 and the matching design of the connecting rod B 32 together form a flexible and stable rotation system. When the sliding key 13 slides in the straight slot 42 and the inclined slot 43 of the stopper 40, it pushes the sliding bar 11 through the guide bar 12, thereby driving the connecting rod A 31 and the connecting rod B 32 to rotate in the hinge slot 24. This rotation not only realizes the conversion of the inward tilting, airtight and translation states of the sliding window, but also ensures the stability and accuracy of the connecting rod B 32 during the action through the design of the hinge slot 24.

[0055] In some embodiments, the front and rear sides of the fixing seat 21 are provided with a plurality of nuts 23 threadedly mounted with the glass sash. The plurality of nuts 23 provided on the front and rear sides of the fixing seat 21 can be threadedly mounted with the glass sash by means of screws. Such a design allows the fixing seat 21 to be firmly fixed on the glass sash, ensuring the structural stability and durability of the entire sliding window assembly. The nuts 23 on the front and rear sides of the fixing seat 21 are connected to the glass sash by means of screw threading, providing a stable foundation for the sliding window assembly. This installation method not only ensures a firm connection between the fixing seat 21 and the glass sash, but also allows fine-tuning during the installation process to adapt to different installation conditions and ensure the correct alignment of the assembly.

[0056] In some embodiments, the connecting rod A 31 is rotatably connected with an eccentric block 33, and a U-shaped hole 44 is provided on the side of the locking block 41 away from the straight groove 42, and the eccentric block 33 is adapted in the U-shaped hole 44 of the locking block 41. An adjustment slot (including but not limited to a hexagonal slot and a cross slot) is provided at the bottom of the eccentric block 33, so that the user can adjust the eccentric position of the eccentric block 33 in the U-shaped hole 44 as needed, thereby changing the position of the locking block 41 on the connecting rod A 31 to adapt to the locking position required by the sliding key 13. The locking block 41 is fixed to the connecting rod A 31 by screws. This design allows the new position of the locking block 41 to be fixed by tightening the screws after adjusting the position of the eccentric block 33, thereby ensuring the locking stability of the sliding key 13 on the locking block 41.

[0057] The cooperation between the eccentric block 33 and the U-shaped hole 44 of the locking block 41, and the design that the locking block 41 is fixed to the connecting rod A 31 by screws, together constitute an adjustable locking mechanism. When the locking position of the sliding key 13 needs to be adjusted, it can be achieved by adjusting the eccentric position of the eccentric block 33 in the U-shaped hole 44. The adjustment slot of the eccentric block 33 allows the user to use tools for precise adjustment. After adjustment, by tightening the screws on the locking block 41, the new position of the locking block 41 can be fixed to ensure the locking stability of the sliding key 13 on the locking block 41.

[0058] In some embodiments, the guide wheel member 50 includes a positioning piece 51 whose bottom is rotatably arranged through a rotating shaft and an end of a connecting rod A 31, and a plurality of guide wheels 52 are arranged on the top of the positioning piece 51. The positioning piece 51 included in the guide wheel member 50 is rotatably arranged through a rotating shaft and an end of a connecting rod A 31. Such a design allows the positioning piece 51 to rotate under the drive of the connecting rod A 31, thereby realizing precise control of the inward tilting action of the sliding window. The plurality of guide wheels 52 arranged on the top of the positioning piece 51 are used to slide in the track groove at the top of the window frame. These guide wheels 52 ensure the smooth movement of the sliding window during the inward tilting process and reduce friction and wear.

[0059] The positioning piece 51 of the guide wheel member 50 is arranged to rotate with the end of the connecting rod A31 through the rotating shaft, so that the positioning piece 51 can rotate with the rotation of the connecting rod A31. When the sliding key 13 slides in the straight groove 42 and the inclined groove 43 of the limiting member 40, it pushes the sliding bar 11 through the guide bar 12, thereby driving the connecting rod A31 and the positioning piece 51 to rotate.

[0060] Example 2

[0061] In order to ensure the stability of the inward tilting action of larger glass sashes, first of all, the size of the sliding bar 11 needs to be lengthened. However, directly setting a conventional long-sized sliding bar will not meet the versatility of market hardware, and the long-sized sliding bar will also be offset at both ends due to the force applied by the inward tilting linkage 30, resulting in not being on the same line, which will affect the stability.

[0062] Therefore, in this embodiment, the sliding bar 11 in the first embodiment is divided into two split bars 14, and the opposite ends of the two split bars 14 are tilted and placed on the connecting pull tab 15. The connecting pull tab 15 is a common hardware on the market, and the design method of tilting the opposite ends of the split bar 14 can be applied to connecting pull tabs 15 of different lengths. In addition, because it is necessary to polarize the inverted linkage members 30, the limit member 40 and the guide wheel member 50 on both sides, that is, the fixing member connected to the two inverted linkage members 30 is divided from an integrated structure to a split structure, such as Figure 6 As shown, the fixed seat 21 is divided into two split seats 27 from the middle, and they correspond to the inner tilting linkage members 30 on both sides respectively; the bottoms of the opposite ends of the two adjacent split seats 27 are provided with a balancing groove 28, and the tilted end of the split strip 14 is provided with a balancing block 16, which can be adapted to the balancing groove 28. Specifically: the sliding of the split strip 14 can drive the tilted end balancing block 16 to be inserted into the balancing groove 28 of the split seat 27. At this time, the connecting pull tab 15 is connected and fixed to the split strip 14. When the split strip 14 is restricted in the balancing groove 28 of the split seat 27 by the balancing block 16, the connecting pull tab 15 also uses the limiting mechanism to ensure that the end is on the same line of balance with the split seat 27. Through this embodiment, it can be conveniently applied to the stability of the inner tilting action process of larger-sized glass sashes.

[0063] Further, such as Figure 7 As shown, it also includes a handle portion 60 and a linkage assembly 70. The handle portion 60 transmits the rotational force to the rack of the linkage assembly 70 through the handle and the gear, so that the rotational motion is converted into a linear motion (not marked in the figure); in addition, the linkage assembly 70 is composed of a plurality of pull bars and flexible bars, which are respectively limited at the four sides and four corners of the glass leaf outer frame. This principle and structure are the conventional motion transmission methods of the hardware sliding door and window system, which will not be elaborated here. In addition, it also includes at least two frame locking members 80, which are fixed on both sides of the inner part of the sliding door and window frame, and are used to adapt to the glass leaf in Example 1 or Example 2 and lock it with it after it is tilted inward, so that the tilted glass leaf can be guaranteed not to continue to move horizontally when it moves to the left or right side of the sliding door and window frame, thereby increasing safety and stability.

[0064] exist Figure 8 In the figure, the frame locking member 80 includes a fixing plate 81, on which a lock buckle A 82 and a lock buckle B 83 are provided, and the lock buckle A82 and the lock buckle B 83 are respectively located on the upper and lower sides of the fixing plate 81, wherein the lock buckle A 82 is provided with an anti-slip straight groove 84, and the notch of the anti-slip straight groove 84 faces downward; and the lock buckle B 83 is provided with an anti-slip arc groove 85, and the notch of the anti-slip arc groove 85 faces outdoors. The pull bars on the left and right sides of the linkage assembly 70 are respectively provided with eccentric lock shafts 71, which are composed of a short shaft 72, a convex plate 73 and a flat head shaft 74. The short shaft 72 is fixed to the side of the pull bar, and a convex plate 73 is provided at one end of the short shaft 72 away from the pull bar through a bearing, and a flat head shaft 74 is fixed at one end of the convex plate 73 away from the short shaft 72. The flat head shaft 74 can be respectively adapted to the anti-slip straight groove 84 and the anti-slip arc groove 85 through the up and down linear movement of the pull bar; in addition, the notch of the anti-slip arc groove 85 faces the outside, so that the flat head shaft 74 can be adapted to the inward tilting state of the glass sash. The rotation of the bearing between the convex plate 73 and the short shaft 72 can facilitate the rotation along the arc edge of the anti-slip arc groove 85 during the inward tilting process, thereby increasing the applicability. The frame locking member 80 and the eccentric lock shaft 71 are both applicable to both Embodiment 1 and Embodiment 2.

[0065] like Figure 6 As shown, a protrusion (not marked in the figure) is provided on the sliding bar 11, that is, located on the side of the sliding key 13, and its purpose is to guide the sliding key 13 and the straight groove 42 of the locking block 41 to increase the stability of the locking block 41 during the matching process, and prevent the locking block 41 from shaking on the connecting rod A 31. This design can be applied to both embodiment 1 and embodiment 2.
