Description

Technical Field

[0001] The invention relates to an adjusting mechanism for doors and windows.

[0002] The present invention also relates to a door and window hinge comprising the door and window regulating mechanism.

[0003] The present invention further provides a door or window comprising the above-mentioned door or window hinge. Background Art

[0004] like Figure 1 As shown, the existing openable and closable doors and windows mainly include a fixed outer frame 10, a door and window sash 20 that can be opened and closed assembled in the fixed outer frame 10, an upper hinge assembly 30 and a lower hinge assembly 40. The door and window sash 20 mainly includes a sash frame 21, a door and window panel 22 (usually glass) fixed in the sash frame 21, and a handle assembly 23 installed on the sash frame 21. The upper side of the sash frame 21 is connected to the fixed outer frame 10 through the upper hinge assembly 30, and the lower side of the sash frame 21 is connected to the fixed outer frame 10 through the lower hinge assembly 40. The upper hinge assembly 30 and the lower hinge assembly 40 are used to realize the opening or closing of the door and window sash 20 relative to the fixed outer frame 10.

[0005] In some doors and windows, an adjustment mechanism is configured on the upper hinge assembly and the lower hinge assembly, and the adjustment mechanism is used to adjust the gap size between the fixed outer frame and the door and window leaf in the left and right directions. For example: in the outward-opening top-hung double-opening window disclosed in the Chinese invention patent document with the authorization announcement number CN105545173B, its hinge assembly has a left and right position adjustment mechanism, and the left and right position adjustment device includes an adjustment seat, a mounting seat and left and right adjustment screws, one end of the left and right adjustment screws is located in the adjustment seat, and the other end of the left and right adjustment screws is threadedly matched with the mounting seat, the adjustment seat is fixedly connected to the mounting seat installed on the upper crossbeam of the movable frame, and the mounting seat is connected to the upper connecting piece; by twisting the left and right adjustment screws, the mounting seat drives the upper connecting piece connected to the upper crossbeam of the movable frame to move towards or away from the fixed frame, thereby fine-tuning the left and right installation positions of the movable frame.

[0006] In order to facilitate transportation, the various components of the door and window are usually packaged separately and transported to the destination for on-site assembly and installation. However, during transportation, the above-mentioned adjustment mechanism is prone to the undesirable phenomenon that the left and right adjustment screws are separated from the adjustment seat, causing the adjustment seat to fall off the mounting seat, which makes the assembly structure of the adjustment mechanism relatively unstable during transportation, which has an adverse effect on the subsequent on-site assembly and installation of the door and window.

[0007] In order to solve the problem that the left and right adjusting screws and the adjusting seat are easily separated during transportation, some manufacturers will additionally configure an outer cover to cover the left and right adjusting screws to prevent the left and right adjusting screws from separating from the adjusting seat; however, this method will increase the number of parts of the adjusting mechanism, increase the cost of the adjusting mechanism, and thus increase the cost of doors and windows. Summary of the invention

[0008] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an adjustment mechanism for doors and windows, which can effectively prevent its components from being separated during transportation.

[0009] To achieve the above-mentioned purpose, the present invention provides an adjustment mechanism for doors and windows, comprising a base for installation on a fixed outer frame in the door and window, an adjustment seat for installation on a sash frame in the door and window, and an adjustment bolt rotatably arranged in the adjustment seat, the adjustment bolt is threadedly connected to the base, and a horizontal transverse limiting portion, a horizontal longitudinal limiting portion and a vertical limiting portion are fixed on the adjustment seat, the horizontal transverse limiting portion limits the adjustment bolt along the axial direction of the adjustment bolt, the horizontal longitudinal limiting portion limits the adjustment bolt and / or the base along the horizontal radial direction of the adjustment bolt, and the vertical limiting portion limits the adjustment bolt and / or the base along the vertical diameter of the adjustment bolt.

[0010] In the above-mentioned door and window adjustment mechanism, by rotating the adjustment bolt, the adjustment bolt can be moved relative to the base along its own axial direction, and the adjustment bolt drives the adjustment seat to move synchronously relative to the base, which also drives the sash frame connected to the adjustment seat to move relative to the fixed outer frame connected to the base, thereby adjusting the gap size between the door and window sash and the fixed outer frame. Under this premise, the components of the door and window adjustment mechanism have been preassembled before transportation. In the door and window adjustment mechanism in the preassembled state, the horizontal transverse limiter limits the axial position of the adjustment bolt to limit the axial disengagement of the adjustment bolt, thereby preventing the adjustment seat and the base from being separated in the horizontal transverse direction; the horizontal longitudinal limiter limits the horizontal longitudinal position of the adjustment bolt and / or the base to limit the horizontal longitudinal movement of the adjustment bolt and / or the base to prevent the adjustment seat and the base from being separated in the horizontal longitudinal direction; the vertical limiter limits the vertical position of the adjustment bolt and / or the base to limit the vertical movement of the adjustment bolt and / or the base to prevent the adjustment seat and the base from being separated in the vertical direction. In this way, the adjusting mechanism for doors and windows in the pre-assembled state effectively limits the relative movement of the adjusting seat and the base in the front-to-back direction, left-to-right direction, and up-and-down direction through the limiting action of the horizontal transverse limiting part, the horizontal longitudinal limiting part, and the vertical limiting part without rotating the adjusting bolt, thereby reliably maintaining the connection relationship between the various components of the adjusting mechanism for doors and windows in the pre-assembled state, avoiding accidental separation of the adjusting seat and the adjusting bolt from the base during transportation, providing better conditions for the subsequent on-site assembly of doors and windows, and facilitating the subsequent on-site assembly and installation of doors and windows.

[0011] Further, the rotatable mounting structure of the adjusting bolt in the adjusting seat is preferably: the adjusting bolt includes a bolt head and a bolt shank, the bolt shank is threadedly connected to the base; the adjusting seat is provided with a communicating head receiving groove and a shank receiving groove, the bolt head is rotatably received in the head receiving groove, and the bolt shank is rotatably received in the shank receiving groove; along the horizontal radial direction of the adjusting bolt, the width of the head receiving groove is greater than the width of the shank receiving groove. In this way, the adjusting seat forms a step portion at the junction of the head receiving groove and the shank receiving groove.

[0012] Preferably, the groove wall surface of the head groove includes a first groove wall surface and a second groove wall surface that are arranged opposite to each other in the axial direction of the adjusting bolt, and the horizontal transverse limiting portion includes a first groove wall surface and a second groove wall surface, and the first groove wall surface and the second groove wall surface abut against both sides of the bolt head along the axial direction of the adjusting bolt. The step portion formed at the junction of the head groove and the rod groove of the adjusting seat and the end structure of the adjusting seat are used to form a horizontal transverse limiting portion for axially limiting the adjusting bolt, thereby simplifying the structure of the adjusting seat.

[0013] Preferably, the groove wall surface of the head receiving groove includes a third groove wall surface and a fourth groove wall surface which are arranged opposite to each other in the horizontal radial direction of the adjusting bolt, and the horizontal longitudinal limiting portion includes the third groove wall surface and the fourth groove wall surface, and the third groove wall surface and the fourth groove wall surface abut against both sides of the bolt head along the horizontal radial direction of the adjusting bolt. The structure of the head receiving groove itself is used to form a horizontal longitudinal limiting portion for horizontally and longitudinally limiting the adjusting bolt, thereby simplifying the structure of the adjusting seat.

[0014] Preferably, along the vertical diameter of the adjusting bolt, the surface of the adjusting seat is provided with an installation opening, and the head receiving groove and the rod receiving groove are both exposed from the installation opening. In this way, when preassembling the adjustment mechanism for doors and windows, the adjusting bolt is first screwed into the base by a preset distance, and then the adjusting seat can be conveniently sleeved on the adjusting bolt through the installation opening, and the bolt head of the adjusting bolt is located in the head receiving groove, and the bolt rod of the adjusting bolt is located in the rod receiving groove, thereby improving the convenience of preassembly operation. In addition, the groove bottom of the head receiving groove away from the installation opening is a first arc groove adapted to the bolt head, so that the bolt head is better accommodated in the head receiving groove; the groove bottom of the rod receiving groove away from the installation opening is a second arc groove adapted to the bolt rod, so that the bolt rod is better accommodated in the rod receiving groove.

[0015] Furthermore, the door and window adjustment mechanism also includes a limit cover plate, which is assembled in the adjustment seat and the base; when the door and window adjustment mechanism is in a pre-assembled state, the limit cover plate blocks the installation opening, which can not only connect the adjustment seat and the base, but also play a role in vertically limiting the adjustment bolt, and ultimately more reliably maintain the connection relationship between the base, the adjustment seat and the adjustment bolt in the door and window adjustment mechanism in the pre-assembled state.

[0016] Furthermore, the assembly structure between the base and the adjustment seat is preferably: an adjustment connection portion is provided at one end of the base close to the adjustment seat, an adjustment screw hole is provided in the adjustment connection portion for threaded engagement with the adjustment bolt, and an adjustment slot is provided in the adjustment seat for sliding engagement with the adjustment connection portion. The sliding engagement between the adjustment slot and the adjustment connection portion improves the stability and accuracy of the movement of the adjustment seat relative to the base during the adjustment process, thereby improving the accuracy and precision of the gap adjustment between the door and window sash and the fixed outer frame.

[0017] Preferably, along the vertical diameter of the adjusting bolt, the adjusting seat is provided with the vertical limiting parts on both sides of the adjusting connection part, and the vertical limiting parts can abut against the adjusting connection part, thereby limiting the vertical movement of the adjusting connection part and playing a role of vertical limiting on the base.

[0018] Furthermore, an adjustment limit groove is provided in the adjustment seat, and an adjustment limit protrusion is provided on the surface of the adjustment connection portion; along the axial direction of the adjustment bolt, the adjustment limit protrusion is movably located in the adjustment limit groove and can abut against the groove walls on both sides of the adjustment limit groove. Through the sliding cooperation between the adjustment limit groove and the adjustment limit protrusion, on the one hand, the stability and accuracy of the movement of the adjustment seat relative to the base during the adjustment process can be improved, and on the other hand, the movement range of the adjustment seat relative to the base during the adjustment process can be limited, which also limits the adjustment range of the gap size between the door and window sash and the fixed outer frame, avoiding accidental separation between the base, the adjustment seat and the adjustment bolt during the adjustment process.

[0019] Preferably, the adjustment seat is provided with a first pre-installation alignment line on the side of the adjustment limit groove, and the surface of the adjustment limit protrusion is provided with a second pre-installation alignment line; when pre-assembling the adjustment mechanism for doors and windows, when the first pre-installation alignment line is aligned with the second pre-installation alignment line, it can be determined that the adjustment mechanism for doors and windows is pre-assembled in place, which facilitates the pre-assembly of the adjustment mechanism for doors and windows.

[0020] Preferably, an installation socket is provided at one end of the adjustment seat facing the base, and the installation socket is distributed on one side of the adjustment slot along the vertical diameter of the adjustment bolt and is connected to the adjustment slot. The installation socket allows the adjustment connecting part to be inserted, which makes it convenient to put the adjustment seat on the adjustment connecting part during pre-assembly, thereby improving the convenience of pre-assembly operation of the adjustment mechanism for doors and windows.

[0021] Furthermore, the adjusting bolt includes a bolt head, a rotation groove is provided on the end face of the bolt head, and a rotation opening is provided at the end of the adjusting seat; along the axial direction of the adjusting bolt, the rotation opening is distributed on one side of the rotation groove and the rotation groove is exposed, so that it is convenient to use an operating part such as a screwdriver to rotate the adjusting bolt, thereby facilitating the adjustment of the gap size between the door and window sash and the fixed outer frame.

[0022] The present invention also provides a hinge for doors and windows, comprising a hinge body and the above-mentioned door and window adjustment mechanism, wherein the hinge body has a frame connecting component for being installed on a fixed outer frame in the door and window, and the base is connected to the frame connecting component.

[0023] The present invention further provides a door and window, comprising a fixed outer frame, door and window sashes that can be opened and closed in the fixed outer frame, and the door and window hinges as described above, wherein the door and window sashes comprise a sash frame and a door and window panel fixed in the sash frame, and the door and window hinges are installed between the upper end of the fixed outer frame and the upper end of the sash frame, and between the lower end of the fixed outer frame and the lower end of the sash frame, and the adjustment seat is fixedly connected to the sash frame.

[0024] As described above, the door and window regulating mechanism, door and window hinge, and door and window according to the present invention have the following beneficial effects:

[0025] The adjusting mechanism for doors and windows in the pre-assembled state effectively limits the relative movement of the adjusting seat and the base in the front-to-back direction, left-to-right direction, and up-and-down direction through the limiting action of the horizontal transverse limiting part, the horizontal longitudinal limiting part and the vertical limiting part without rotating the adjusting bolt, thereby reliably maintaining the connection relationship between the various components of the adjusting mechanism for doors and windows in the pre-assembled state, avoiding accidental separation of the adjusting seat and the adjusting bolt from the base during transportation, providing better conditions for subsequent on-site assembly of doors and windows, and facilitating subsequent on-site assembly and installation of doors and windows.

[0090] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0091] The present invention relates to a door and window adjustment mechanism, a door and window hinge including the door and window adjustment mechanism, and a door and window including the door and window hinge. For the convenience of description, in the following embodiments, the definitions of various directions are as follows: the width direction of the door and window is defined as the left-right direction, the height direction of the door and window is defined as the up-down direction, and the thickness direction of the door and window is defined as the front-back direction, which is also the outdoor and indoor direction. Based on this, Figure 1 In the view shown, the left and right sides of the paper are the left and right directions respectively, the upper and lower sides of the paper are the upper and lower directions respectively, the front and back of the paper are the rear and front directions respectively; and the rear direction is the indoor direction, and the front direction is the outdoor direction.

[0092] like Figure 1 As shown, the door and window involved in the present invention comprises a fixed outer frame 10, a door and window sash 20 and a hinge for the door and window.

[0093] The fixed outer frame 10 is fixed at the window opening of the building, and the fixed outer frame 10 is fixedly arranged; usually, the fixed outer frame 10 includes a pair of vertical outer frame profiles 101 extending up and down and a pair of horizontal outer frame profiles 102 extending left and right, and the vertical outer frame profiles 101 and the horizontal outer frame profiles 102 are preferably integrally formed aluminum profiles.

[0094] The door and window sash 20 is assembled in the fixed outer frame 10 so as to be opened and closed by door and window hinges. The door and window sash 20 includes a sash frame 21, a door and window panel 22 fixed in the sash frame 21, and a handle assembly 23 installed on the sash frame 21; usually, the sash frame 21 includes a pair of vertical sash frame profiles 211 extending downward and a pair of horizontal sash frame profiles 212 extending left and right, and the vertical sash frame profiles 211 and the horizontal sash frame profiles 212 are preferably both integrally formed aluminum profiles; the door and window panel 22 is preferably glass, and the handle assembly 23 is installed on the left vertical sash frame profile 211.

[0095] Hinges for doors and windows are also called hinges for doors and windows. A set of hinges for doors and windows is assembled between the upper horizontal sash frame profile 212 of the sash frame 21, the upper horizontal outer frame profile 102 of the fixed outer frame 10, and the right vertical outer frame profile 101. The hinge for doors and windows is defined as an upper hinge assembly 30, and the upper hinge assembly 30 is distributed at the upper right corner of the door and window sash 20. A set of hinges for doors and windows is assembled between the lower horizontal sash frame profile 212 of the sash frame 21, the lower horizontal outer frame profile 102 of the fixed outer frame 10, and the right vertical outer frame profile 101. The hinge for doors and windows is defined as a lower hinge assembly 40, and the lower hinge assembly 40 is distributed at the lower right corner of the door and window sash 20. Under the joint action of the upper hinge assembly 30 and the lower hinge assembly 40, the door and window sash 20 can be opened inwards and the upper end can be tilted inwards; therefore, the door and window involved in the present application is an inward opening and tilting door and window, and the door and window hinge involved in the present application is a concealed inward opening and tilting hinge. Of course, in other embodiments, the door and window hinge can also be an inward opening hinge or a concealed hinge.

[0096] Figures 2 to 4 The door and window hinge shown is an upper hinge assembly 30. Figures 5 to 7 The door and window hinge shown is a lower hinge assembly 40. Figures 2 to 4 As shown, or as Figures 5 to 7As shown, the door and window hinges involved in the present invention include a hinge body 90 and a door and window adjustment mechanism, the hinge body 90 has a frame connecting component installed on a fixed outer frame 10 in the door and window; the door and window adjustment mechanism includes a base 50, an adjustment seat 60 and an adjustment bolt 70; the adjustment bolt 70 is rotatably arranged in the adjustment seat 60, and the adjustment bolt 70 is threadedly connected to the base 50; the base 50 is connected to the frame connecting component in the hinge body 90, and the base 50 is installed on the fixed outer frame 10 through the frame connecting component; the adjustment seat 60 is fixedly connected to the sash frame 21, and the adjustment seat 60 is installed on the sash frame 21. After the doors and windows are installed, when the door and window sash 20 is in the closed state, the axial direction of the adjusting bolt 70 is in the left and right direction, and the upper hinge assembly 30 and the lower hinge assembly 40 are both in the retracted state; rotating the adjusting bolt 70 can make the adjusting bolt 70 move left or right along its own axial direction relative to the base 50, and the adjusting bolt 70 is rotatably retained in the adjusting seat 60, and the adjusting bolt 70 drives the adjusting seat 60 to move left or right synchronously relative to the base 50; the base 50 is installed on the fixed outer frame 10 through the hinge body 90, and the adjusting seat 60 is fixedly connected to the sash frame 21 of the door and window sash 20, and the adjusting seat 60 drives the sash frame 21 to move left or right relative to the fixed outer frame 10, thereby adjusting the size of the gap between the door and window sash 20 and the fixed outer frame 10 in the left and right direction, and this adjustment is fine-tuning.

[0097] Furthermore, in order to facilitate the transportation of doors and windows, the components of the doors and windows are separately packaged during transportation, and then assembled and installed on site after being transported to the site. During transportation, the adjustment mechanism for doors and windows is in a pre-assembled state. Figure 2 and Figure 3 As shown, or as Figure 5 and Figure 6As shown, the adjusting bolt 70 is assembled in the adjusting seat 60, and the adjusting bolt 70 is pre-screwed into the base 50 to a preset distance. In order to enable the door and window adjustment mechanism to reliably maintain its pre-assembled state during transportation, the adjusting seat 60 is fixed with a horizontal transverse limiting portion 61, a horizontal longitudinal limiting portion 62 and a vertical limiting portion 63, the horizontal transverse direction is also the left and right direction, the horizontal longitudinal direction is the front and back direction, and the vertical direction is the up and down direction. Among them, the horizontal transverse limiting portion 61 limits the adjusting bolt 70 along the axial direction of the adjusting bolt 70, restricts the adjusting bolt 70 from being disengaged in the left and right direction, and prevents the adjusting seat 60 and the base 50 from being separated from each other in the horizontal transverse direction. The horizontal longitudinal limiting portion 62 limits the adjusting bolt 70, or the base 50, or the adjusting bolt 70 and the base 50 along the horizontal radial direction of the adjusting bolt 70, restricts the forward and backward movement of the adjusting bolt 70, or the base 50, or the adjusting bolt 70 and the base 50, and prevents the adjusting seat 60 and the base 50 from being separated from each other in the horizontal longitudinal direction. The vertical limiting portion 63 limits the adjusting bolt 70, or the base 50, or the adjusting bolt 70 and the base 50 along the vertical diameter of the adjusting bolt 70, restricts the up and down movement of the adjusting bolt 70, or the base 50, or the adjusting bolt 70 and the base 50, and prevents the adjusting seat 60 and the base 50 from separating up and down in the vertical direction.

[0098] Therefore, when the above-mentioned door and window adjustment mechanism is in the pre-assembled state, it effectively limits the relative movement of the adjustment seat 60 and the base 50 in the front-to-back direction, left-right direction and up-down direction through the limiting action of the horizontal transverse limiting part 61, the horizontal longitudinal limiting part 62 and the vertical limiting part 63, without rotating the adjusting bolt 70, and reliably maintains the connection relationship between the various components of the door and window adjustment mechanism in the pre-assembled state, avoids the accidental fall of the adjustment seat 60 from the base 50 during transportation, improves the stability of the pre-assembled structure of the door and window adjustment mechanism, provides better conditions for the subsequent on-site assembly of doors and windows, and facilitates the subsequent on-site assembly and installation of doors and windows. In particular, the present application uses the structure of the adjustment seat 60 itself to achieve the limitation in all directions, does not increase the number of components of the door and window adjustment mechanism, and reasonably suppresses the cost of the door and window adjustment mechanism.

[0099] Furthermore, if Figures 2 to 4 As shown, in the upper hinge assembly 30, the adjustment seat 60 is fixed to the upper end of the upper transverse sash frame profile 212 of the sash frame 21 by two front and rear fixing screws 110, the adjustment seat 60 is assembled on the left end side of the base 50, and the adjustment bolt 70 is screwed rightward into the left end of the base 50. Figures 5 to 7As shown, in the lower hinge assembly 40, the adjustment seat 60 is fixed to the lower end of the lower horizontal sash frame profile 212 of the sash frame 21 by two front and rear fixing screws 110, the adjustment seat 60 is assembled on the left end side of the base 50, and the adjustment bolt 70 is screwed rightward into the left end of the base 50. The structure of the adjustment seat 60 in the upper hinge assembly 30 and the matching structure of the adjustment seat 60 and the left section of the base 50 are exactly the same as the structure of the adjustment seat 60 in the lower hinge assembly 40 and the matching structure of the adjustment seat 60 and the left section of the base 50, but they are arranged symmetrically from top to bottom. In this embodiment, the base 50 is also used as a rod component of the hinge body 90, so the structure of the right section of the base 50 in the upper hinge assembly 30 is slightly different from the structure of the right section of the base 50 in the lower hinge assembly 40.

[0100] The following description takes the door and window adjustment mechanism in the upper hinge assembly 30 as an example, and the door and window sash 20 is in a closed state, and describes the matching structure of the adjustment seat 60 and the left section of the base 50 in the door and window adjustment mechanism. When the door and window sash 20 is in a closed state, the upper hinge assembly 30 is in a retracted state, and the axial direction of the adjustment bolt 70 is exactly in the left-right direction.

[0101] like Figure 8 and Fig. 9 As shown, the adjusting bolt 70 includes a bolt head 71 and a bolt shank 72 integrally extending axially to the right from the right end of the bolt head 71. The diameter of the bolt head 71 is larger than the diameter of the bolt shank 72. The outer periphery of the bolt shank 72 is threaded, and the bolt shank 72 is threadedly connected to the base 50. Fig.10 As shown, the adjusting seat 60 is provided with a communicating head groove 64 and a rod groove 65, which are arranged side by side on the left and right. The bolt head 71 is rotatably accommodated in the head groove 64, and the bolt rod 72 is rotatably accommodated in the rod groove 65, thereby rotatably retaining the adjusting bolt 70 in the adjusting seat 60.

[0102] Preferably, if Fig. 9 and Fig.10 As shown in the figure, along the horizontal radial direction of the adjusting bolt 70, that is, in the front-to-back direction, the width of the head groove 64 is adapted to the diameter of the bolt head 71, and the width of the stem groove 65 is adapted to the diameter of the bolt stem 72, and the width of the head groove 64 is greater than the width of the stem groove 65. In this way, the adjusting seat 60 forms a step portion 612 at the junction of the head groove 64 and the stem groove 65. In addition, the adjusting seat 60 performs chamfering at the four corners of the head groove 64, so that the four corners of the head groove 64 are formed with chamfered corners 613.

[0103] like Figure 8 and Fig. 9 ,as well as Fig.13 and Fig.14As shown, the left end of the base 50 near the adjustment seat 60 is integrally provided with an adjustment connection part 51, and an adjustment screw hole 511 threadedly matched with the adjustment bolt 70 is opened in the adjustment connection part 51, so that the adjustment bolt 70 is threadedly connected to the left end of the base 50.

In the process of adjusting the left and right gap between the door and window sash 20 and the fixed outer frame 10, the adjusting bolt 70 is rotated to drive the adjusting bolt 70 and the adjusting seat 60 to move left or right relative to the adjusting connecting part 51 at the left end of the base 50. In this process, the sliding cooperation between the adjusting groove 67 and the adjusting connecting part 51 can improve the stability and accuracy of the left and right movement of the adjusting seat 60 relative to the base 50 during the adjustment process, thereby improving the accuracy and precision of adjusting the gap size between the door and window sash 20 and the fixed outer frame 10.

[0104] Furthermore, the horizontal transverse limiting portion 61 and the horizontal longitudinal limiting portion 62 both adopt the groove wall surface of the head receiving groove 64, thereby simplifying the structure of the adjustment seat 60.

The first groove wall surface 641 and the second groove wall surface 642 are arranged opposite to each other in the axial direction of the adjusting bolt 70, and the first groove wall surface 641 and the second groove wall surface 642 are respectively abutted on the left and right sides of the bolt head 71, on the one hand, the adjusting bolt 70 is rotatably held in the adjusting seat 60, and on the other hand, the adjusting bolt 70 is prevented from moving left and right in the adjusting seat 60, thereby limiting the adjusting bolt 70 in the left and right directions; in this way, the first groove wall surface 641 and the second groove wall surface 642 constitute the above-mentioned horizontal transverse limiting portion 61. The third groove wall surface 643 and the fourth groove wall surface 644 are arranged front and back oppositely in the horizontal radial direction of the adjusting bolt 70, and the third groove wall surface 643 and the fourth groove wall surface 644 are respectively abutted against the front side and the rear side of the bolt head 71, on the one hand, the adjusting bolt 70 is rotatably held in the adjusting seat 60, and on the other hand, the adjusting bolt 70 is prevented from moving back and forth in the adjusting seat 60, thereby limiting the adjusting bolt 70 in the front and back directions; in this way, the third groove wall surface 643 and the fourth groove wall surface 644 constitute the above-mentioned horizontal longitudinal limiting portion 62. Therefore, the present application utilizes the step portion 612 formed at the junction of the head receiving groove 64 and the rod receiving groove 65 of the adjusting seat 60, and the structure of the head receiving groove 64 in the adjusting seat 60, to form a horizontal transverse limiting portion 61 for axially limiting the adjusting bolt 70, and a horizontal longitudinal limiting portion 62 for horizontally and longitudinally limiting the adjusting bolt 70, thereby simplifying the structure of the adjusting seat 60.

The fifth groove wall surface 652 and the sixth groove wall surface 653 are respectively abutted against the front side and the rear side of the bolt rod 72, further preventing the adjustment bolt 70 from moving forward and backward in the adjustment seat 60, and improving the reliability of the front-back limiting of the adjustment bolt 70. In this way, in addition to the third groove wall surface 643 and the fourth groove wall surface 644 of the head receiving groove 64, the horizontal longitudinal limiting portion 62 also includes the fifth groove wall surface 652 and the sixth groove wall surface 653 of the rod receiving groove 65.

[0106] Preferably, if Figures 9 to 12As shown, along the vertical diameter of the adjusting bolt 70, that is, along the up and down direction, the adjusting seat 60 is arranged with a vertical limiting portion 63 on the upper side of the adjusting connection portion 51, and the adjusting seat 60 is also arranged with a vertical limiting portion 63 on the lower side of the adjusting connection portion 51. The upper vertical limiting portion 63 can abut against the upper surface of the adjusting connection portion 51, and the lower vertical limiting portion 63 can abut against the lower surface of the adjusting connection portion 51, thereby limiting the up and down movement of the adjusting connection portion 51 in the adjusting seat 60, that is, limiting the relative up and down movement between the base 50 and the adjusting seat 60, thereby playing a role of vertical limiting on the base 50.

[0107] Furthermore, if Figures 10 to 12 As shown, the entity part of the adjustment seat 60 includes an upper cover plate 614, a front cover plate 615 and a rear cover plate 616 which are symmetrically arranged on the front and rear sides of the upper cover plate 614, and a left cover plate 617 arranged on the left side of the upper cover plate 614. The head receiving groove 64 is surrounded by the upper cover plate 614, the front cover plate 615, the rear cover plate 616 and the left cover plate 617. The rod receiving groove 65 is surrounded by the upper cover plate 614, the front cover plate 615 and the rear cover plate 616. In this way, the left cover plate 617 abuts against the left end side of the adjusting bolt 70, and the right end side of the adjusting seat 60 is an open structure, so that the adjusting slide groove 67 passes through from left to right. The upper vertical limit portion 63 is distributed at the right end of the upper cover plate 614; there are two lower vertical limit portions 63, one of which extends backwards as a whole from the lower right end of the front cover plate 615, and the other vertical limit portion 63 extends forwards as a whole from the lower right end of the rear cover plate 616.

[0108] Preferably, if Figures 10 to 12 As shown, the right end surface of the front cover plate 615 and the right end surface of the rear cover plate 616 are both avoidance slopes 618, and the avoidance slopes 618 are arranged in a manner that they are inclined downward as they go to the left. In the adjustment seat 60, the upper vertical limiter 63 is distributed at the upper right end of the avoidance slope 618, and the two lower vertical limiters 63 are distributed at the lower left end of the avoidance slope 618. The arrangement of the avoidance slope 618 forms a mounting socket 610 at the right side of the two lower vertical limiters 63 at the right end of the adjustment seat 60, and the mounting socket 610 is distributed at the lower side of the adjustment slot 67 in the up-down direction and is connected to the adjustment slot 67. When preassembling the adjustment mechanism for doors and windows, the adjustment connection part 51 can be inserted into the adjustment slide groove 67 through the installation socket 610, avoiding interference of the two vertical limit parts 63 on the lower side with the installation of the adjustment connection part 51. It is convenient to relatively put the right end of the adjustment seat 60 on the adjustment connection part 51 during preassembly, so as to realize assembly without press-in interference, thereby improving the convenience of preassembly operation of the adjustment mechanism for doors and windows.

[0109] Furthermore, if Figures 9 to 12As shown, an installation opening 66 is formed between the lower end of the front cover plate 615 and the lower end of the rear cover plate 616, and the installation opening 66 is also set on the lower surface of the adjustment seat 60, and the lower end of the head receiving groove 64 and the lower end of the rod receiving groove 65 are completely exposed from the installation opening 66. In this way, when pre-assembling the adjustment mechanism for doors and windows, the adjustment bolt 70 is first screwed into the base 50 by a preset distance, and then the adjustment seat 60 can be conveniently sleeved on the adjustment bolt 70 through the installation opening 66, and the bolt head 71 of the adjustment bolt 70 is located in the head receiving groove 64, and the bolt rod 72 of the adjustment bolt 70 is located in the rod receiving groove 65, so as to improve the convenience of pre-assembly operation. In addition, the upper end bottom of the head groove 64 away from the mounting opening 66 is a first arc groove 645 adapted to the bolt head 71, so that the bolt head 71 can be better accommodated in the head groove 64; the upper end bottom of the rod groove 65 away from the mounting opening 66 is a second arc groove 651 adapted to the bolt rod 72, so that the bolt rod 72 can be better accommodated in the rod groove 65.

[0110] Preferably, if Figures 10 to 12 As shown, two fixing holes 619 symmetrically distributed front to back are provided in the adjustment seat 60, the front fixing hole 619 passes through the upper cover plate 614 and the front cover plate 615 up and down, the rear fixing hole 619 passes through the upper cover plate 614 and the rear cover plate 616 up and down, and two fixing screws 110 are respectively passed through the two fixing holes 619, thereby fixing the adjustment seat 60 on the upper horizontal sash frame profile 212 of the sash frame 21.

[0111] Furthermore, if Figure 8 , Fig.11 and Fig.12 As shown, an adjustment limit groove 68 is provided in the adjustment seat 60, and the adjustment limit groove 68 is provided on the upper cover plate 614 and distributed on the left side of the upper vertical limit portion 63; Figure 8 and Fig.13 As shown, an upwardly protruding adjustment limit protrusion 52 is integrally provided on the upper surface of the adjustment connection portion 51. Along the axial direction of the adjustment bolt 70, the adjustment limit protrusion 52 is movably located in the adjustment limit groove 68 and can abut against the left and right groove walls of the adjustment limit groove 68. In this way, through the sliding cooperation between the adjustment limit groove 68 and the adjustment limit protrusion 52, on the one hand, the stability and accuracy of the left and right movement of the adjustment seat 60 relative to the base 50 during the adjustment process can be improved, and on the other hand, the left and right movement range of the adjustment seat 60 relative to the base 50 during the adjustment process can be limited, which also limits the adjustment range of the gap size between the door and window sash 20 and the fixed outer frame 10, and avoids accidental separation between the base 50, the adjustment seat 60 and the adjustment bolt 70 during the adjustment process.

[0112] Preferably, if Figure 8As shown, in the front-to-back direction, the width of the adjustment limit groove 68 is adapted to the width of the adjustment limit protrusion 52, so that there can be a clearance fit between the adjustment limit protrusion 52 and the limit adjustment groove; in this way, the front side groove wall and the rear side groove wall of the adjustment limit groove 68 play a certain limiting role on the adjustment limit protrusion 52, further limiting the base 50 front and back to prevent the base 50 from being displaced in the front-to-back direction.

[0113] Preferably, if Figure 8 , Figures 10 to 12 As shown, the upper surface of the adjustment seat 60 is provided with a first pre-installed alignment line 69 on the front side and the rear side of the adjustment limit groove 68, and the first pre-installed alignment line 69 is a groove structure extending forward and backward; the upper surface of the adjustment limit protrusion 52 is provided with a second pre-installed alignment line 53 on the front side and the rear side thereof, and the second pre-installed alignment line 53 is also a groove structure extending forward and backward. When pre-assembling the door and window adjustment mechanism, first screw the adjustment bolt 70 into the adjustment screw hole 511 of the base 50 for a small section, then install the adjustment seat 60, and then continue to screw the adjustment bolt 70 into the base 50 until the first pre-installed alignment line 69 is aligned with the second pre-installed alignment line 53. At this time, the door and window adjustment mechanism is pre-assembled in place, and the horizontal transverse limit portion 61, the horizontal longitudinal limit portion 62 and the vertical limit portion 63 on the adjustment seat 60 each play their respective limiting functions. Therefore, by setting the first pre-installation alignment line 69 on the adjustment seat 60 and the second pre-installation alignment line 53 on the base 50, it is convenient to judge whether the adjustment mechanism for doors and windows is pre-assembled in place, thereby improving the convenience of operation.

[0114] Furthermore, if Figure 4 As shown, a rotation groove 73 is provided on the left end surface of the bolt head 71; Fig.11 As shown, a rotation opening 611 is provided at the left end of the adjustment seat 60, and the rotation opening 611 penetrates the upper cover plate 614 upwards and penetrates the left cover plate 617 to the left; along the axial direction of the adjustment bolt 70, the rotation opening 611 is distributed on the left side of the rotation groove 73, and the rotation groove 73 is exposed. In this way, it is convenient for a screwdriver or other rotation operating component to be inserted into the rotation groove 73 of the adjustment bolt 70 from the rotation opening 611, driving the adjustment bolt 70 to rotate, thereby facilitating the adjustment of the gap between the door and window sash 20 and the fixed outer frame 10.

[0115] Furthermore, if Figure 3 and Figure 4As shown, the door and window adjustment mechanism further includes a limit cover plate 80, which is assembled on the lower end side of the adjustment seat 60 and the base 50; when the door and window adjustment mechanism is in the pre-assembled state, the limit cover plate 80 blocks the installation opening 66, and the limit cover plate 80 covers the adjustment bolt 70, as well as the head receiving groove 64 and the rod receiving groove 65 of the adjustment seat 60. The limit cover plate 80 can not only connect the adjustment seat 60 and the base 50, but also play a role in vertically limiting the adjustment bolt 70, avoiding the upper and lower separation between the adjustment bolt 70 and the adjustment seat 60, and finally more reliably maintaining the connection relationship between the base 50, the adjustment seat 60 and the adjustment bolt 70 in the door and window adjustment mechanism in the pre-assembled state. In this embodiment, the limit cover plate 80 is an existing cover plate in the upper hinge assembly 30, which does not increase the number of components of the door and window adjustment mechanism, and reduces the cost of the door and window adjustment mechanism.

[0116] Preferably, the base 50 and the adjustment seat 60 are both integrally formed parts, such as metal parts or injection molded parts.

[0117] In summary, the pre-assembly process of the door and window regulating mechanism having the above structure is as follows:

[0120] 3. Fig.15c As shown, the adjusting bolt 70 is screwed rightward into the base 50, and the adjusting bolt 70 drives the adjusting seat 60 to move rightward together. At this time, since the vertical limit portion 63 on the right end side of the upper cover plate 614 in the adjusting seat 60 abuts against the adjusting limit protrusion 52 of the base 50, the adjusting seat 60 is in an inclined state with the right end slightly lifted;

[0121] 4. Fig.15d As shown, continue to screw the adjusting bolt 70 to the right, and the adjusting bolt 70 drives the adjusting seat 60 to move to the right together until the first pre-installation alignment line 69 is aligned with the second pre-installation alignment line 53. At this time, the door and window adjustment mechanism is in a pre-assembled state, as shown in FIG. Figure 8 and Fig. 9As shown, the first groove wall surface 641 and the second groove wall surface 642 constituting the horizontal transverse limiting portion 61 abut against the left and right sides of the bolt head 71, respectively, and limit the adjustment bolt 70 in the left-right direction; the third groove wall surface 643 and the fourth groove wall surface 644 constituting the horizontal longitudinal limiting portion 62 abut against the front and rear sides of the bolt head 71, respectively, and limit the adjustment bolt 70 in the front-back direction; the three vertical limiting portions 63 abut against the upper side, the lower left side, and the lower right side of the adjustment connection portion 51, respectively, and limit the adjustment seat 60 in the upper and lower directions. In this way, the adjustment bolt 70 and the adjustment seat 60 are prevented from falling off from the base 50, and the structural stability of the door and window adjustment mechanism in the pre-assembled state is improved.
