Description

Technical Field

[0001] The present invention relates to the technical field of building doors and windows, and in particular to a tilt-and-slide window sliding device and an tilt-and-slide window. Background Art

[0002] Door and window hardware determines how they are opened and plays a vital role in their performance. Casement and sliding are two of the most common opening methods for building doors and windows. However, both opening methods have some shortcomings in actual use. Casement windows have good sealing effects and can achieve large-area ventilation, but opening inwards will occupy a large indoor space, and opening outwards poses a greater risk of falling. Sliding windows do not occupy indoor space and are not prone to falling, but their sealing performance is poor. Therefore, users need an opening method that can simultaneously meet the requirements of large-area opening, excellent sealing performance, and safety and reliability. Currently, there are several products on the market that can achieve both inward tilting and translation (sliding and pulling) functions, but they generally have unreasonable structures and unstable products. For example, the unreasonable structure of the sliding part causes the window sash to move after tilting inwards, and the movement transition is not smooth during the opening and closing process. Therefore, market recognition is not high. Summary of the Invention

[0003] The present invention aims to address the problems of conventional tilt-and-slide windows, such as instability, movement after tilting, and unsmooth transitions between opening and closing. The present invention provides a sliding device for a tilt-and-slide window and a tilt-and-slide window, which enable smooth transitions between opening and closing, and maintain stability and prevent movement in both the tilted and slidable positions.

[0004] In order to solve the above technical problems, an embodiment of the present invention discloses an inward-tilt translation window sliding device, comprising: a sliding seat, a sliding bar, a positioning seat, a support seat and a swing arm; the sliding seat is used to be arranged in a track of the window frame and can slide relative to the track along a first direction; the sliding bar is connected to the sliding seat through a sliding shaft, the sliding shaft can slide relative to the sliding seat along the first direction, the sliding bar can rotate around the sliding shaft, and along the first direction, the sliding bar includes a first end and a second end; the support seat is used to be connected to the window sash; one end of the swing arm is located in the sliding seat and is rotatably connected to the sliding seat, The other end of the arm is located outside the sliding seat and is rotatably connected to the support seat, and the swing arm can switch between a first state and a second state; in the first state, the support seat is located above the sliding seat, the swing arm is located on the side of the sliding seat and close to the sliding seat, the second end of the sliding bar is engaged with the positioning seat, and the first end of the sliding bar is separated from the one end of the swing arm; in the second state, the swing arm is away from the side of the sliding seat and rotates relative to the sliding seat, the first end of the sliding bar is engaged with the one end of the swing arm, and the second end of the sliding bar is separated from the positioning seat.

[0005] By adopting the above technical solution, the window sash can be opened while remaining parallel to the window frame, that is, the window sash is separated from the window frame. When the window sash is opened to the maximum state parallel to the window frame, the swing arm switches from the first state to the second state, that is, the second end of the sliding bar separates from the positioning seat, the first end of the sliding bar is engaged with one end of the swing arm, and the swing arm is away from the side of the sliding seat and forms a set angle with the sliding seat, thereby realizing the limit function of the window sash in the maximum open state before translation. The window sash can achieve translation (push-pull) action as the sliding seat slides in the track. When the window sash is pulled toward the positioning seat along the first direction, the sliding seat slides in the track and the window sash also slides. When the sliding bar is hit by the positioning seat, the sliding stops. At this time, the sliding shaft slides relative to the sliding seat along the first direction. In the process of the sliding bar hitting the positioning seat, the first end of the sliding bar is separated from one end of the swing arm, and the swing arm begins to rotate. At this time, the sliding shaft rotates relative to the sliding seat, and the second end of the sliding bar is buckled into the positioning seat and engaged with it.

Exemplarily, when the handle 1 is horizontal, the window sash can be translated; when the handle of the handle 1 is downward, the window sash is completely locked; when the handle of the handle 1 is upward, the window sash can be tilted inward. The transmission 2 is provided on the window sash and is linked with the handle 1 through a square shaft. The transmission 2 realizes a certain stroke of transmission under the linkage action of the handle 1. The C-groove connecting rod 3 is provided on both sides of the window sash along the first direction and above it along the second direction. The transmission 2 can drive multiple C-groove transmission rods 3 for transmission. Exemplarily, there are four C-groove connecting rods 3.

[0049] The flip rod 4 is provided on the window sash, and the flip rod 4 is connected to the transmission device 2 through the C-groove connecting rod 3. The anti-slip device 5 is provided on the window frame and can cooperate with the flip rod 4 to achieve the complete locking function of the window sash. The latch seat 6 is provided on the window frame. When the window sash is in the inward tilted state, the flip rod 4 can be inserted into the latch seat 6 to achieve a relatively stable state of the window sash and avoid shaking. The lower front sliding assembly 7 is provided on the lower edge of the window sash along the second direction and connects the window sash and the window frame at the same time. The fixed block 8 is provided on the window sash and can be connected to the lower front sliding assembly 7, thereby achieving the purpose of the lower front sliding assembly 7 connecting the window sash and the window frame. The lower connecting rod 9 is provided at the lower end of the window sash along the second direction and connects the lower front sliding assembly 7 and the sliding device 10. The sliding device 10 is provided on the lower edge of the window sash, and the sliding device 10 and the lower front sliding assembly 7 are respectively located on both sides of the window sash along the first direction. For example, the lower front sliding assembly 7 and the sliding device 10 have basically the same structure.

[0050] The positioning seat 11 is provided on the window frame and is located on the lower side of the window frame along the first direction near the sliding device 10. It can engage with the sliding device 10 to lock the window sash, thereby preventing it from shaking. The locking rod 12 is provided on the side of the window sash along the first direction near the positioning seat 11. The locking rod 12 and the flip rod 4 are located on opposite sides of the window sash along the first direction. The lock seat 13 is provided on the window frame and can cooperate with the locking rod 12 to completely lock the window sash. For example, three lock seats 13 are provided. The corner turner B14 and the corner turner A21 are respectively provided at the two corners above the window sash along the first direction to achieve a vertical state at the two corners of the window sash. The corner turner B14 and the corner turner A21 can cooperate with the lock seat 13 to completely lock the window sash. The fixing member 15 is provided on the window frame and is located on the upper side of the window frame. The upper front sliding assembly 16 connects the window sash and the window frame.

[0051] The upper sliding device 17 connects the window sash and the window frame. The upper sliding device 17 has the same structure and shape as the upper front sliding assembly 16. The fixing member 15 is located on the outer side of the upper sliding device 17 along the first direction. The upper connecting rod 18 is located on the C-groove connecting rod 3 along the third direction ( Figure 1On the other side (shown in the Y direction), the upper connecting rod 18 connects the upper front sliding assembly 16 and the upper sliding device 17. The upper latch frame member 22 is provided on the window frame.

The upper anti-collision block 24 and the lower anti-collision block 25 are respectively located on the upper and lower sides of the window frame along the second direction. When the window sash is translated to the maximum state, the window sash collides with the upper buffer block 24 and the lower buffer block 25, which is buffered, reducing the impact sound and avoiding component damage.

[0052] refer to Figures 2 to 4 The embodiment of the present application provides a tilt-and-slide window sliding device 10, comprising: a sliding seat 101, a sliding bar 102, a positioning seat 11, a support seat 103 and a swing arm 104. The sliding seat 101 is used to be arranged in a track (not shown) of a window frame and can move along a first direction ( Figure 2 The sliding bar 102 is connected to the sliding seat 101 via a sliding shaft 108. The sliding shaft 108 can slide relative to the sliding seat 101 along a first direction. The sliding bar 102 can rotate around the sliding shaft 108. Along the first direction, the sliding bar 102 includes a first end 1020 of the sliding bar and a second end 1021 of the sliding bar.

[0053] For example, the slide bar 102 moves along the second direction ( Figure 3 There is a lowest point on the upper surface of the sliding seat 101 (shown in the Z direction), that is, the upper surface of the sliding bar 102 has a set slope. The support seat 103 is used to connect with the window sash. One end of the swing arm 104 is located inside the sliding seat 101 and is rotatably connected to the sliding seat 101. The other end of the swing arm 104 is located outside the sliding seat 101 and is rotatably connected to the support seat 103, that is, the swing arm 104 connects the window sash and the window frame through the sliding seat 101 and the support seat 103. Exemplarily, the connection between the swing arm 104 and the sliding seat 101 is achieved through a shaft 1043 and a bearing 1044. The swing arm 104 can rotate around the shaft 1043, and the bearing 1044 can reduce the rotational friction during the rotation of the swing arm 104.

[0054] The swing arm 104 of the embodiment of the present application can be in the first state ( Figure 4 shown) and the second state ( Figure 2 In the first state, the support base 103 is located above the sliding base 101, the swing arm 104 is located on the side of the sliding base 101 and close to the sliding base 101, the second end 1021 of the sliding bar is engaged with the positioning base 11, and the first end 1020 of the sliding bar is separated from one end of the swing arm 104. Figure 2 and Figure 5In the second state, the swing arm 104 is away from the side of the sliding seat 101 and rotates relative to the sliding seat 101, the first end 1020 of the sliding bar is engaged with one end of the swing arm 104, and the second end 1021 of the sliding bar is separated from the positioning seat 11.

[0055] Using the above technical solution, refer to Figure 1 and Figure 6 When the handle 1 is in the horizontal position, by pulling the handle 1 outward, that is, along the third direction ( Figure 1 The window sash 26 can be opened while being parallel to the window frame 27, that is, the window sash 26 is separated from the window frame 27. When the window sash 26 is opened to the maximum along the third direction and parallel to the window frame 27, that is, Figure 6 and Figure 7 Status shown. Figures 2 to 5 The swing arm 104 switches from the first state to the second state, that is, the second end 1021 of the sliding bar is separated from the positioning seat 11, the first end 1020 of the sliding bar is engaged with one end of the swing arm 104, and the swing arm 104 is away from the side of the sliding seat 101 and rotates relative to the sliding seat 101, realizing the limit function of the maximum opening state of the window sash 26 in the third direction. Figure 1 and Figure 2 , along the first direction ( Figure 1 When the handle 1 is pulled (as shown in the X direction), the window sash can realize translation (pushing and pulling) action as the sliding seat 101 slides in the track, that is, the window sash is in a translation state at this time. When the window sash continues to translate and is opened to the maximum state, the window sash realizes synchronous braking and impact buffering of the extreme position along the first direction with the upper anti-collision block 24 and the lower anti-collision block 25, that is, at this time the window sash is buffered and stops moving by colliding with the upper anti-collision block 24 and the lower anti-collision block 25.

[0056] refer to Figure 1 and Figure 4 , the handle 1 is pulled in the opposite direction, i.e., along the first direction ( Figure 1When the sliding bar 102 is struck by the positioning seat 11 (shown in the X direction) and pulled toward the positioning seat 11, the sliding seat 101 slides within the track, and the window sash also slides therewith. When the sliding bar 102 is struck by the positioning seat 11, the sliding stops. At this time, the sliding shaft 108 slides relative to the sliding seat 101 in the first direction. In the process of the sliding bar 102 striking the positioning seat 11, the first end 1020 of the sliding bar 102 disengages from one end of the swing arm 104. The swing arm 104 begins to rotate and gradually approaches the sliding seat 101. At this time, the sliding shaft 108 rotates relative to the sliding seat 101, and the second end 1021 of the sliding bar is pressed down and buckled into the positioning seat 11 to engage with it. The latch sash upper member 23 cooperates with the latch frame upper member 22 to realize the self-locking function. At this time, the window sash is in the closed state. When the handle 1 is rotated downward 90 degrees (handle downward), the transmission device 2 realizes a certain stroke of transmission under the linkage action of the handle 1, and the transmission device 2 then drives multiple C-groove transmission rods 3 to transmit. At this time, the flip rod 4 cooperates with the anti-slip device 5, the lock rod 12 cooperates with the lock seat 13, and the angler B14 and the angler A21 cooperate with the lock seat 13 to realize the complete locking function of the window sash 26 and the window frame 27. Figure 8 shown.

[0057] In some possible implementations, reference Figures 3 to 5 The first end 1020 of the sliding bar is elastically connected to the sliding seat 101, and can move along the first direction ( Figure 4 When the sliding seat 101 strikes the positioning seat 11 (as shown in the X direction), the first end 1020 of the sliding bar separates from one end of the swing arm 104, and the second end 1021 of the sliding bar engages with the positioning seat 11. Specifically, when the sliding seat 101 strikes the positioning seat 11 in the first direction, the sliding bar 102 slides in the direction opposite to the collision direction to provide a buffer, separating the first end 1020 of the sliding bar from one end of the swing arm 104 and further engaging the second end 1021 of the sliding bar with the positioning seat 11, thereby locking the swing arm 104 in the first state and further preventing the window sash from wandering.

[0058] In some possible implementations, reference Figure 3 and Figure 9 , further comprising an elastic member 105, one end of the elastic member 105 abuts against the first end 1020 of the sliding bar, and the other end elastically abuts against the sliding seat 101. Exemplarily, the elastic member 105 is a spring, and the end of the first end 1020 of the sliding bar is provided with a protrusion 1023, one end of the elastic member 105 is sleeved on the protrusion 1023, and the other end abuts against the sliding seat 101. Figure 2 and Figure 3 , when the sliding seat 101 moves along the first direction ( Figure 2When the sliding bar 102 strikes the positioning seat 11 (as shown in the X direction), the elastic member 105 is compressed in the direction opposite to the collision direction. The expansion and contraction of the elastic member 105 at this point causes the sliding bar 102 to slide relative to the sliding seat 101 in the first direction. Furthermore, the second end 1021 of the sliding bar engages the positioning seat 11, locking the swing arm 104 in the first state and further preventing the window sash from moving.

[0059] In some possible implementations, reference Figure 1 and Figure 5 The first end 1020 of the sliding bar includes a latch 1020a and a boss 1020b, and the second end 1021 of the sliding bar includes a hook 1021a. For example, the latch 1020a is cylindrical, and the boss 1020b is spherical at one end connected to the swing arm 104. The boss 1020b and the latch 1020a are tightly attached to form an integrated structure and are located on the lower surface of the first end 1020 of the sliding bar. The latch 1020a is arranged along the second direction ( Figure 1 The length of the hook 1021a is greater than the length of the boss 1020b along the second direction; the hook 1021a is a hook-shaped structure. For example, the hook 1021a is formed by bending the second end 1021 of the sliding bar downward along the second direction.

[0060] refer to Figure 3 and Figure 5 The outer circumference of one end of the swing arm 104 includes a slot 1040. The top surface of one end of the swing arm 104 is provided with a ramp structure 1041, and the boss 1020b is located above the ramp structure 1041. Exemplarily, the slot 1040 is a vertical groove extending along the second direction on the outer circumference of the swing arm 104, and is semi-cylindrical in shape for the insertion of the latch 1020a. The ramp structure 1041 is spiral in shape.

[0061] refer to Figure 10 , the swing arm 104 is in the first state, the hook 1021a is engaged with the positioning seat 11; Figure 5 In the second state, the swing arm 104 has the latch 1020a inserted into the slot 1040. After the latch 1020a is separated from the slot 1040, as the swing arm 104 switches from the second state to the first state, the boss 1020b slides along the ramp structure 1041, allowing the hook 1021a to engage with the positioning seat 11. That is, only when the latch 1020a is separated from the slot 1040 can the hook 1021a engage with the positioning seat 11. Since the positioning seat 11 is fixed to the window frame, the engagement of the hook 1021a with the positioning seat 11 locks the swing arm 104, thereby stabilizing the window sash and preventing it from shaking.

[0062] In some possible implementations, reference Figure 3 and Figure 10, further comprising a spring 106, the spring 106 being located between the sliding bar 102 and the rolling device 107 of the sliding seat 101, the sliding bar 102 being elastically connected to the sliding seat 101 via the spring 106, illustratively, the spring 106 being in the shape of a curved sheet, and moving along the second direction ( Figure 3 The Z direction is shown in FIG. 1 ) and is attached to the lower surface of the sliding bar 102 .

[0063] During the process of switching from the first state to the second state, that is, in preparation for the translation of the window sash, the sliding bar 102 moves forward ( Figure 10 The first end 1020 of the sliding bar moves toward one end of the swing arm 104 so that the latch 1020a is inserted into the slot 1040, thereby locking the swing arm 104 in the second state, effectively avoiding the swinging of the window sash in the translation state, and facilitating the translation and opening of the window sash.

[0064] During the switching process from the second state to the first state, the slide bar 102 rotates in the opposite direction around the slide axis 108 ( Figure 10 The latch 1020a is disengaged from the slot 1040, the boss 1020b slides up along the slope structure 1041, and the second end 1021 of the sliding bar moves toward the positioning seat 11. Under the action of the spring 106, the second end 1021 of the sliding bar is pressed down, and the hook 1021a is engaged with the positioning seat 11, that is, the swing arm 104 is locked in the first state, which effectively prevents the window sash from wandering when it is tilted inward and closed.

[0065] In some possible implementations, reference Figures 2 to 4 The sliding seat 101 has an axis hole 1011, and the sliding shaft 108 passes through the axis hole 1011 to connect the sliding bar 102 and the sliding seat 101. The axis hole 1011 is a rounded rectangular shape. The sliding shaft 108 slides or rotates with the sliding bar 102 in the axis hole 1011. The sliding seat 101 moves along the first direction ( Figure 2 When the sliding bar 102 hits the positioning seat 11 (as shown in the X direction in the middle), the sliding bar 102 slides in the direction opposite to the impact direction, that is, the sliding shaft 108 also slides in the shaft hole 1011 at this time, and the elastic member 105 is compressed at this time, so that the sliding bar 102 is buffered and returns to the position close to the positioning seat 11 along the first direction; at the same time, under the action of the spring piece 106, the sliding bar 102 rotates in the second direction, and the sliding shaft 108 rotates in the shaft hole 1011 at this time, and the first end 1020 of the sliding bar is tilted up, and the second end 1021 of the sliding bar sinks, thereby causing the hook 1021a to engage with the positioning seat 11, thereby realizing the locking state of the swing arm 104 in the first state.

[0066] In some possible implementations, reference Figure 10The rolling device 107 includes an axle 1070 and a wheel 1071. The wheel 1071 is rotatably connected to the sliding seat 101 through the axle 1070. The spring 106 is provided between the wheel 1071 and the sliding bar 102. For example, the spring 106 is curved, so that a portion of it is in close contact with the lower surface of the sliding bar 102 and the outer peripheral surface of the wheel 1071, and the other portion is away from the lower surface of the sliding bar 102. Figure 5 When the sliding seat 101 collides with the positioning seat 11, the pin 1020a disengages from the slot 1040, and the boss 1020b slides to the highest point from the slope structure 1041, the spring 106 cooperates with the first end 1020 of the sliding bar to tilt upward, and the second end 1021 of the sliding bar sinks, so that the hook 1021a is engaged with the positioning seat 11, realizing the locking state of the swing arm 104 in the first state, further making the window sash stable and preventing shaking.

[0067] In some possible implementations, reference Figure 3 and Figure 7 The support base 103 includes a first portion 1030 and a second portion 1031. The first portion 1030 is L-shaped and fixedly connected to a corner of the window sash 26. The second portion 1031 is cylindrical. A through hole 1042 is formed at the other end of the swing arm 104. A rotating shaft 1032 passes through the through hole 1042 to rotatably connect the second portion 1031 and the swing arm 104. For example, the rotating shaft 1032 cooperates with a bearing 1034 and a retaining ring 1033 to connect the swing arm 104 and the support base 103. That is, one end of the swing arm 104 is connected to the sliding base 101, and the other end is connected to the support base 103. The sliding base 101 is located on the window frame 27, and the support base 103 is located on the window sash 26. In other words, the swing arm 104 connects the window sash 26 and the window frame 27. Exemplarily, the sliding seat 101 slides on the track in the window frame 27 , thereby driving the swing arm 104 to move, and further driving the support seat 103 to slide, that is, the sliding of the sliding seat 101 indirectly drives the translational sliding of the window sash 26 .

[0068] In some possible implementations, reference Figure 5 and Figure 10 The positioning seat 11 is provided with a slot 110 for engaging with the hook 1021a. For example, the positioning seat 11 is L-shaped as a whole, and the slot 110 is provided at a portion of the positioning seat 11 extending along the second direction.

[0069] The embodiment of the present invention further discloses an inward-tilt-and-slide window based on the above-mentioned inward-tilt-and-slide window sliding device, including an upper sliding device 17 used in conjunction with the sliding device 10 .

[0070] refer to Figure 1 、 Figure 11 and Figure 12The upper sliding device 17 includes a fixed seat 170, a sliding rod 171, a short connecting rod 19, a sliding block 172, a short connecting plate 173, a long connecting plate 174, and a fixing member 15. The fixed seat 170 is fixedly mounted to the window sash 26. For example, the fixed seat 170 is mounted to the window sash 26 via screws. One end of the sliding rod 171 is rotatably connected to the fixed seat 170, and the sliding rod 171 is provided with a blocking portion 1710.

[0071] For example, both ends of the fixing base 170 are fixed to the window sash 26 by screws, and the fixing base 170 is fixed along the first direction ( Figure 11 A hole is formed in the middle of the window sash 26 (shown in the X direction) to connect with the sliding rod 171. The short connecting rod 19 is mounted on the window sash 26 and is provided with a fixing pin 190. When the window sash 26 is in a translational state or a closed state, the fixing pin 190 abuts against the blocking portion 1710. When the window sash 26 transitions from the translational state or the closed state to the inward tilting state, the short connecting rod 19 slides in a first direction, and the fixing pin 190 separates from the blocking portion 1710.

[0072] The sliding block 172 is used to be arranged on the window frame 27. For example, the sliding block 172 can slide relative to the window frame 27 along a first direction. One end of the short connecting plate 173 is connected to the sliding rod 171 through a sliding rivet 175. For example, the short connecting plate 173 is stepped. The long connecting plate 174 is rotatably connected to the short connecting plate 173. One end of the long connecting plate 174 is rotatably connected to one end of the sliding rod 171, and the other end is rotatably connected to the sliding block 172, that is, the long connecting plate 174 is respectively connected to the short connecting plate 173, the sliding rod 171 and the sliding block 172, and a sliding pin 1740 is provided on the long connecting plate 174. The fixing member 15 is used to be fixed to the window frame 27. When the window sash is in the closed state, the sliding pin 1740 is engaged with the fixing member 15, as shown in FIG. Figure 14 shown.

[0073] refer to Figure 13 and Figure 14 When the window sash is in the closed state, the fixing pin 190 abuts against the blocking portion 1710, and the sliding block 172, the long connecting plate 174, the short connecting plate 173, the sliding rod 171 and the fixing seat 170 overlap in the second direction. Figure 12 and Figure 15 , the window sash is in the translation state, the fixing pin 190 and the blocking portion 1710 are against each other, and the sliding block 172 and the fixing seat 170 are along the third direction ( Figure 15 The sliding rod 171 overlaps with the fixing seat 170 in the second direction, and the sliding rod 171 and the long connecting plate 174 are set at an acute angle.

[0074] For example, when the window sash is in translation, the fixing pin 190 abuts against the end of the blocking portion 1710 close to the sliding rivet, and when the window sash is in a closed state, the fixing pin 190 abuts against the end of the blocking portion 1710 away from the sliding rivet. Figure 11 and Figure 16 When the window sash is in the inward tilted state, the fixing pin 190 is separated from the blocking portion 1710, the sliding block 172 is separated from the fixing seat 170 and the spacing distance in the third direction reaches the maximum, the sliding rod 171 is rotated out and set at an acute angle with the fixing seat 170, and the sliding rod 171 is at a set angle with the long connecting plate 174.

[0075] Using the above technical solution, refer to Figure 1 、 Figure 12 and Figure 16 When the handle 1 is rotated upward by 180° (handle upward), the flip rod 4 is separated from the anti-slip device 5, and the lock rod 12 is separated from the lock seat 13. At the same time, the flip rod 4 is inserted into the latch seat 6 under the drive of the C-groove connecting rod 3, and the short connecting rod 19 is rotated in the first direction ( Figure 12 The fixing pin 190 is disengaged from the blocking portion 1710 by sliding in the X direction.

[0076] At this time, the handle 1 is pulled outward, that is, pulled toward the user's body. The sliding rod 171 begins to rotate around the connection with the fixing seat 170 under the action of the pulling force, and the window sash 26 begins to tilt inward. The sliding rivet slides. When the sliding block 172 and the fixing seat 170 are moved along the third direction ( Figure 12 When the distance (indicated by the Y direction) reaches the maximum, the inward tilt action is completed, as shown in Figure 11 and Figure 17 When the window sash is tilted inward, the pin portion of the tilting rod 4 is located below the anti-dropout device 5, the end of the tilting rod 4 is inserted into the latch seat 6, the lock rod 12 is in contact with the lock seat 13, and the sliding bar 102 in the sliding device 10 is engaged with the positioning seat 11. The above state can prevent the window sash 26 from moving when the window sash is tilted inward.

[0077] refer to Figure 11 and Figure 13 When the window sash is in the inward tilt state, the handle is pushed in the direction opposite to the user's body, the sliding rivet 175 slides, and the fixed seat 170 gradually approaches the sliding block 172, that is, the window sash 26 approaches the window frame 27. When the sliding block 172, the long connecting plate 174, the short connecting plate 173, the sliding rod 171 and the fixed seat 170 overlap in the second direction, as shown in FIG. Figure 14 As shown, the window sash completes the closing action. Figure 1During this process, the upper part 22 of the lock frame cooperates with the upper part 23 of the lock sash to achieve self-locking, and the angler A21 collides with the lock seat 13 to release the anti-misoperation restriction of the handle 1. At this time, when the handle 1 rotates downward 90° (the handle is downward), the transmission device 2 realizes a certain stroke of transmission under the linkage action of the handle 1, and the transmission device 2 then drives multiple C-groove transmission rods 3 to transmit. At this time, the flip rod 4 cooperates with the anti-slip device 5, the lock rod 12 cooperates with the lock seat 13, the angler B14 cooperates with the lock seat 13, and the angler A21 cooperates with the lock seat 13 to achieve the complete locking function of the window sash 26 and the window frame 27, that is, Figure 8 Status shown.

[0078] According to another specific embodiment of the present invention, Figure 11 and Figure 18 , the sliding rod 171 is provided with an elongated hole 1711, a retaining spring 1712 is installed in the elongated hole 1711, the sliding rod 171 and the short connecting plate 173 are connected by sliding in the retaining spring 1712 through a sliding rivet 175. For example, the lower surface of the sliding rod 171 along the second direction is provided with an elongated groove 1713, the elongated groove is communicated with the elongated hole 1711, the overall size of the elongated groove 1713 is larger than the size of the elongated hole 1711, and a clamping portion 1713a and a clamping groove 1713b are provided on the plane where the elongated groove 1713 and the elongated hole 1711 are connected. The retaining spring 1712 is provided along the first direction ( Figure 18 The two free ends of the retaining spring 1712 are engaged with the retaining groove 1713b, thereby fixing the retaining spring 1712 on the sliding rod 171, and further better limiting the sliding rivet 175, so that the window sash tends to be stable in various states.

[0079] According to another specific embodiment of the present invention, Figure 18 The clamping spring 1712 includes a first clamping space 1712a, a second clamping space 1712b and a third clamping space 1712c. Figure 14 and Figure 18 When the window sash is in the closed state, the sliding rivet 175 is located at one end of the long hole 1711, that is, located in the first clamping space 1712a; Figure 15 and Figure 18 , when the window sash is in translation, the sliding rivet 175 is located in the middle of the long hole 1711, that is, in the second clamping space 1712b; Figure 11 and Figure 18When the window sash is tilted inward, the sliding rivet 175 is located at the other end of the elongated hole 1711, that is, at the third engaging space 1712c. For example, the engaging portion 1713a is located within the third engaging space 1712c. That is, the retaining spring 1712 is secured to the sliding rod 171 by securing the third engaging space 1712c between the engaging portion 1713a and the sliding rod 171. Furthermore, the sliding rivet 175 is better positioned within the elongated hole 1711, ensuring that the window sash 26 is stable in all positions.

[0080] For example, first engaging space 1712a is located at the free end of retaining spring 1712 and is shaped like a trapezoid. Second engaging space 1712b is located in the middle of retaining spring 1712 and is formed by two semicircular shapes. Third engaging space 1712c is located at the closed end of retaining spring 1712 and is shaped like a trapezoid. First engaging space 1712a is larger than second engaging space 1712b, which in turn is larger than third engaging space 1712c. This facilitates better positioning of sliding rivet 175 within elongated hole 1711, ensuring stability of window sash 26 in all positions.

[0081] According to another specific embodiment of the present invention, Figure 12 The sliding rod 171 is provided with a buffer block 1714, which abuts against the window frame 27 to reduce noise during the opening and closing of the window sash 26. For example, when the sliding rod 171 collides with the metal window frame 27, the buffer block 1714 first collides with the window frame 27. Since the buffer block 1714 is made of elastic material, it can reduce noise during the collision.

[0082] According to another specific embodiment of the present invention, Figure 11 The long connecting plate 174 and the short connecting plate 173 are connected by rivets 1730; the sliding rod 171 and the fixed seat 170 are connected by rivets 1715; and the sliding rod 171 and the long connecting plate 174 are connected by long rivets 1741. For example, the long connecting plate 174 and the short connecting plate 173, and the sliding rod 171 and the fixed seat 170 are all connected by rivets to achieve rotational connection. Similarly, the sliding rod 171 and the long connecting plate 174 are also connected by long rivets 1741 to achieve rotational connection during the opening and closing process of the window sash.

[0083] According to another specific embodiment of the present invention, Figure 11 and Figure 15, the sliding block 172 is rotatably connected to the long connecting plate 174 via the rotating shaft 1720. For example, the sliding block 172 is rotatably connected to the long connecting plate 174, so that the long connecting plate 174 rotates relative to the sliding block 172, further increasing or decreasing the angle between the long connecting plate 174 and the sliding block 172. When the window sash is in the translation and inward tilt state, the long connecting plate 174 and the sliding block 172 are set at an obtuse angle, while in the closed state of the window sash, Figure 14 , the long connecting plate 174 and the sliding block 172 are arranged at a right angle, and the connection between the two is along the second direction ( Figure 14 overlap (shown in the Z direction).

[0084] Although the present invention has been illustrated and described with reference to certain preferred embodiments thereof, it should be understood by those skilled in the art that the above description is provided as a further detailed description of the present invention in conjunction with specific embodiments thereof, and that the specific implementation of the present invention is not limited to these descriptions. Those skilled in the art may make various changes in form and details, including simple deductions or substitutions, without departing from the spirit and scope of the present invention.
