Description

Technical Field

[0001] This invention relates to the field of door and window technology, and in particular to a handle mounting structure, a handle mounting method, and a sliding door and window including the handle mounting structure. Background Technology

[0002] Currently, sliding doors and windows are widely used in the construction industry due to their advantages such as ease of operation, small footprint, and relatively low cost. At the same time, with technological advancements and diversified decoration needs, the functions and applications of sliding doors and windows are constantly expanding, leading to the development of large sliding doors and windows.

[0003] Generally, large sliding doors and windows, compared to traditional sliding doors and windows, place higher demands on the overall structural strength of the product and the installation strength of its various components. For example, large sliding doors and windows are equipped with large handles, which require greater pushing and pulling force when pushing and pulling. Therefore, the installation structure of the large handles must be more reliable to prevent problems such as loosening or falling off later.

[0004] Prior art: Chinese utility model patent CN213330407U discloses a handle connector for easy handle disassembly, including a base, an adjusting part, and an elastic locking part. The adjusting part includes an adjusting screw and an adjusting block, with one end of the adjusting screw screw screwed into the adjusting block. The adjusting part extends into the hollow cavity of the base through a first through hole on a first side of the base. The elastic locking part is located on the side wall of the base and faces the adjusting part, locking the adjusting part extending into the base. A flexible steel rope is connected to the outside of the elastic locking part. Although this handle connector can be used with handles of various types and specifications, it has a large number of parts, relatively high cost, and increases the complexity of the overall structure. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a handle mounting structure that can reduce the number of parts and is better suited for large sliding doors and windows.

[0006] To achieve the above objectives, the present invention provides a handle mounting structure, including a base for fixing to a door or window frame, a door or window handle mounted on the base, and a first fastener for fixing the base and the door or window handle together. The base has a handle mounting cavity, an insertion port on the surface of the base facing the door or window handle, and a locking hole for the first fastener to be screwed into. Both the insertion port and the locking hole communicate with the handle mounting cavity. The base has a stepped portion on the cavity wall of the handle mounting cavity. The door or window handle includes a handle body, a handle insertion portion extending from the handle body toward the base, and a handle stepped portion fixed to the outer periphery of the handle insertion portion.

[0007] When the handle insertion part is inserted into the handle mounting cavity through the insertion port, and the first fastener is screwed into the base through the locking hole and tightened, the first fastener, the handle insertion part, and the seat step part are in close contact with each other along the screwing direction of the first fastener into the base; along the insertion direction of the handle insertion part into the handle mounting cavity, the handle body and the base are in close contact, and the seat step part is distributed on the outside of the handle step part.

[0008] This application tightens the first fastener to ensure a tight fit between the handle insertion part and the seat step part, as well as between the handle body and the base. The seat step part is located on the outer side of the handle step part, and both are positioned close together in the insertion direction of the handle insertion part. This restricts movement of the handle insertion part in the opposite direction of its insertion, preventing it from dislodging from the base, and also restricts relative movement between the handle insertion part and the base in the tightening direction of the first fastener, thereby improving the tensile and compressive strength of the door and window handle. Ultimately, the handle mounting structure of this application, while securing the door and window handle to the base, can withstand significant pushing and pulling forces, making it well-suited for large sliding doors and windows. Furthermore, the handle mounting structure of this application requires only three components: the base, the door and window handle, and the first fastener. This reduces the number of required components, resulting in a simple, reliable, and easily implemented overall structure, effectively lowering costs.

[0009] Furthermore, the insertion direction of the handle insertion portion is perpendicular to the screwing direction of the first fastener; the first fastener has a fastening extension section extending from the locking hole and located in the handle mounting cavity; in particular, the outer periphery of the fastening extension section is provided with a locking conical surface, and the outer periphery of the handle insertion portion is provided with a locking inclined surface, the inclination of the locking conical surface being equal to the inclination of the locking inclined surface. During the process of the first fastener being screwed into the base through the locking hole, the fastening extension section extends towards the handle insertion portion until the locking conical surface on the first fastener contacts and engages with the locking inclined surface on the outer periphery of the handle insertion portion, the locking inclined surface being distributed on the side of the fastening extension section facing away from the handle body; subsequently, as the first fastener continues to be screwed in, the fastening extension section continues to extend from the locking hole, and through the contact engagement of the locking conical surface and the locking inclined surface, both the handle insertion portion is driven to translate towards the seat step portion and the handle insertion portion is driven to move along its insertion direction, thereby causing the handle body to move towards the base until the first fastener... A fastener is tightened in the base; at this time, the locking conical surface and the locking inclined surface are still in surface contact and tightly fitted. The first fastener applies a force F perpendicular to the locking inclined surface to the handle insertion part at the contact point between the locking conical surface and the locking inclined surface. This force F has components in both the screwing direction of the first fastener and the insertion direction of the handle insertion part, thereby making the first fastener, the handle insertion part and the seat step more reliably fitted in the screwing direction of the first fastener, and making the handle body and the base more reliably fitted in the insertion direction of the handle insertion part, ensuring the overall strength of the handle mounting structure and making it better suited for large sliding doors and windows.

[0010] Furthermore, along the extension direction of the first fastener, a limiting locking groove is provided on the side of the handle insertion portion facing the first fastener, and the locking inclined surface is part of the groove wall surface of the limiting locking groove; the handle step portion is provided on the side of the handle insertion portion away from the first fastener, that is, the limiting locking groove and the handle step portion are provided on a pair of opposing surfaces of the handle insertion portion; along a direction perpendicular to both the insertion direction of the handle insertion portion and the screwing direction of the first fastener, the groove wall surface of the limiting locking groove has limiting surfaces distributed on both sides of the fastening extension; when the first fastener is tightened in the base, the fastening extension is in close contact with the limiting surfaces, thereby restricting the relative movement between the handle insertion portion and the first fastener in a direction perpendicular to both the insertion direction of the handle insertion portion and the screwing direction of the first fastener, thus restricting the movement of the door and window handle relative to the base in this direction, making the door and window handle more reliably fixed in the base.

[0011] Preferably, the limiting surface is inclined as it moves further away from the bottom of the limiting locking groove and further away from the fastening extension section. In this way, the distance between a pair of limiting surfaces gradually increases in the direction away from the bottom of the limiting locking groove, making the limiting locking groove roughly a flared structure. This facilitates the insertion of the first fastener into the limiting locking groove, and also facilitates the tightening operation of the first fastener.

[0012] Preferably, the first fastener is a countersunk screw, and the locking hole is a threaded hole that engages with the fastener. With this structure, the head of the first fastener does not protrude from the base, resulting in a better overall appearance for the handle mounting structure and enhancing the aesthetics of the sliding doors and windows.

[0013] Furthermore, the end face of the handle body facing the pedestal is the first reference surface, and the end face of the handle insertion part facing the seat step is the second reference surface. The first reference surface and the second reference surface are perpendicular to each other. The handle step is distributed on one side of the second reference surface along the insertion direction of the handle insertion part. When the first fastener is tightened in the pedestal, the first reference surface contacts and engages with the pedestal surface, and the second reference surface abuts against the seat step. By setting mutually perpendicular first and second reference surfaces on the door and window handle, the processing accuracy of the door and window handle is improved, thereby increasing the reliability of the tight fit between the door and window handle and the pedestal, thus making the door and window handle more reliably fixed in the pedestal.

[0014] Preferably, the end of the seat step near the handle step is provided with a first arcuate surface, and the end of the handle step near the seat step is provided with a second arcuate surface; when the first fastener is tightened in the pedestal, the second arcuate surface is close to the inner side of the first arcuate surface along the insertion direction of the handle insertion part, which can not only prevent the handle step from coming out of the pedestal, but also make the pedestal at the seat step and the door and window handle at the handle step have smooth surfaces.

[0015] Furthermore, when the handle insertion part is inserted into the handle mounting cavity through the insertion port, there is a movable gap between the handle insertion part and the cavity wall of the handle mounting cavity; or, in other words, the outline size of the insertion port and the outline size of the handle mounting cavity are both larger than the outline size of the handle insertion part, which facilitates the insertion operation of the handle insertion part.

[0016] Furthermore, the handle body includes a grip portion and symmetrically fixed bent connecting portions at both ends along the length of the grip portion. There are two bases, each located at the end of each bent connecting portion away from the grip portion. The handle insertion portion is fixed to the end face of each bent connecting portion facing the base. In this way, the overall handle mounting structure experiences balanced force, improving its ability to withstand larger pushing and pulling forces, making it better suited for large sliding doors and windows.

[0017] Preferably, the door and window handle is an integral component, which gives it good structural strength and the ability to withstand greater pushing and pulling forces, thus making it more suitable for large sliding doors and windows.

[0018] The present invention also provides a handle installation method for the above-mentioned handle mounting structure, comprising the following steps:

[0019] S1. Fix the base at the preset installation position of the door / window sash frame of the sliding door / window;

[0020] S2. Insert the handle insertion part of the door and window handle into the handle mounting cavity through the insertion port of the base;

[0021] S3. Adjust the position of the handle insertion part in the handle mounting cavity so that the handle insertion part moves toward the seat step part;

[0022] S4. Screw the first fastener into the locking hole of the base until the first fastener is tightened.

[0023] The present invention provides a sliding door and window, including a fixed outer frame and a sliding door and window sash movably mounted on the fixed outer frame. The sliding door and window sash includes a door and window sash frame and a door and window sash panel installed on the door and window sash frame. The sliding door and window sash is equipped with a handle mounting structure as described above, and the base is fixedly connected to the door and window sash frame.

[0024] Furthermore, the base is fixedly connected to the door and window frame by a second fastener, which is a countersunk screw; the end face of the handle body facing the base covers the second fastener, improving the appearance of the sliding door and window.

[0025] As described above, the handle mounting structure and method, as well as the sliding doors and windows, of the present invention have the following beneficial effects:

[0026] 1. The handle installation structure involved in this application can withstand a large pushing and pulling force while fixing the door and window handle to the base, and thus can be well applied to large sliding doors and windows.

[0027] 2. The handle installation structure involved in this application only requires three types of components: a base, a door and window handle, and a first fastener. The required number of components is small, the overall structure is simple, reliable, and easy to implement, effectively reducing costs. Attached Figure Description

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0086] like Figure 1As shown, this application relates to the field of building door and window technology, and in particular to a handle mounting structure, a handle mounting method of the handle mounting structure, and a sliding door and window equipped with the handle mounting structure. The sliding door and window involved in this application is preferably a large sliding door and window with a relatively large size; therefore, the handle mounting structure provided in this application is preferably a handle mounting structure suitable for large sliding doors and windows.

[0087] For ease of description, in the following embodiments, the directions are defined as follows: the width direction of the sliding door / window is defined as the left-right direction, the height direction is defined as the up-down direction, and the thickness direction is defined as the front-back direction. The thickness direction of the sliding door / window is also the direction between the interior and exterior, with the exterior direction being the front direction and the interior direction being the rear direction. Based on this, Figure 1 In the view shown, the left and right sides of the paper represent the left and right directions, the top and bottom sides represent the top and bottom directions, and the front and back sides represent the back and front directions. Alternatively, Figure 3 and Figure 7 In the view shown, the left and right sides of the paper are the left and right directions, respectively; the top and bottom sides of the paper are the back and front directions, respectively; and the front and back sides of the paper are the bottom and top directions, respectively.

[0088] like Figures 1 to 3 As shown, the sliding door and window involved in this application includes a fixed outer frame 50 and multiple sliding door and window sashes 60; the fixed outer frame 50 is fixed in the opening of the building, and the fixed outer frame 50 is fixedly installed; the multiple sliding door and window sashes 60 are all movably assembled in the fixed outer frame 50, and the movement of the sliding door and window sashes 60 relative to the fixed outer frame 50 can be left and right translation or front and back rotation. Each sliding door and window sash 60 includes a door and window sash frame 10 and a door and window sash panel 70 installed in the door and window sash frame 10, and the door and window sash panel 70 is preferably a glass panel; the door and window sash frame 10 includes a pair of vertically extending and horizontally distributed sash frame profiles 101 and a pair of horizontally extending and vertically distributed sash frame profiles 102, both of which are aluminum profiles.

[0089] like Figures 1 to 3 As shown, each sliding door / window sash 60 is also equipped with a handle mounting structure. The handle mounting structure includes a base 20, a door / window handle 30, and a first fastener 40. The base 20 is fixedly connected to the vertical profile 101 of the door / window frame 10, thereby fixing the handle mounting structure as a whole onto the door / window frame 10 of the sliding door / window sash 60. The door / window handle 30 is mounted on the base 20, and preferably a large handle to accommodate large sliding doors and windows. The first fastener 40 secures the base 20 and the door / window handle 30 together. The handle mounting structure is assembled on the indoor or outdoor side of the sliding door / window sash 60 according to actual needs. The following... Figure 1 Taking the example of a handle mounting structure assembled on the interior side of a sliding door / window sash 60, the base 20 is fixed to the rear surface of the vertical profile 101 of the door / window sash frame 10, and the door / window handle 30 is mounted on the rear side of the base 20. To improve the structural reliability of the handle mounting structure and make it better suited for large sliding doors and windows, the handle mounting structure in this application preferably adopts the following structure.

[0090] like Figure 4 and Figure 5 ,as well as Figures 9 to 12 As shown, the base 20 has a handle mounting cavity 21 inside, and an insertion port 22 is provided on the rear surface of the base 20 facing the door / window handle 30. The insertion port 22 is also the rear end opening of the handle mounting cavity 21. The base 20 has a locking hole 23 for the first fastener 40 to be screwed in. Both the insertion port 22 and the locking hole 23 are connected to the handle mounting cavity 21. The base 20 has an inwardly protruding seat step 24 on the cavity wall of the handle mounting cavity 21. The locking hole 23 and the seat step 24 are arranged opposite to each other along the screwing direction of the first fastener 40 into the base 20. Preferably, the first fastener 40 is screwed into the base 20 in the left direction, so the locking hole 23 and the seat step portion 24 are arranged opposite each other in the left and right direction, and the locking hole 23 extends left and right; in this embodiment, the locking hole 23 is distributed on the right side of the handle mounting cavity 21; the seat step portion 24 protrudes to the right from the left side cavity wall of the handle mounting cavity 21, so the base 20 forms a seat fitting area 26 on the front side of the seat step portion 24, and the seat fitting area 26 is part of the handle mounting cavity 21.

[0091] like Figure 4 and Figure 5 ,as well as Figures 13 to 16 As shown, the door and window handle 30 includes a handle body 31, a handle insertion part 32, and a handle step part 33; the handle body 31 is used by the user to push and pull the door and window sash 60; the handle insertion part 32 is fixed on the front end surface of the handle body 31 facing the base 20, that is, the handle insertion part 32 extends forward from the front end surface of the handle body 31 toward the base 20; the handle step part 33 protrudes to the left from the left side surface of the handle insertion part 32, and a handle fitting area 37 is formed on the left side of the handle insertion part 32 directly behind the handle step part 33, and the handle fitting area 37 is the outer peripheral empty area of ​​the handle insertion part 32.

[0092] When fixing the base 20 and the door / window handle 30, first insert the handle insertion part 32 into the handle mounting cavity 21 through the insertion port 22 (i.e., forward). Then, screw the first fastener 40 into the locking hole 23 from the right side of the base 20 to the left. The insertion direction of the handle insertion part 32 into the base 20 is forward, and the screwing direction of the first fastener 40 is leftward. When the handle insertion part 32 is inserted forward into the handle mounting cavity 21 through the insertion port 22, and the first fastener 40 is screwed into the base 20 to the left through the locking hole 23 and tightened, as... Figure 6 and Figure 7 As shown, along the screwing direction of the first fastener 40 into the base 20, the first fastener 40, the handle insertion part 32, and the seat step part 24 are tightly attached to each other from right to left; along the insertion direction of the handle insertion part 32 into the handle mounting cavity 21, the front end of the handle body 31 is tightly attached to the rear end of the base 20, and the two are in surface contact. The seat step part 24 is distributed on the outside (i.e., the rear side) of the handle step part 33. In other words, there is a very small gap between the front end of the seat step part 24 and the rear end of the handle step part 33, so that the seat step part 24 and the handle step part 33 do not contact each other in the front-back direction, but are very close to each other.

[0093] Furthermore, this application also provides a handle installation method for the above-mentioned handle mounting structure, comprising the following steps in sequence:

[0094] S1, such as Figure 17 As shown, the base 20 is fixed at the preset installation position of the door and window sash frame 10 of the sliding door and window;

[0095] S2, such as Figure 19a As shown, the handle insertion part 32 of the door / window handle 30 is inserted forward into the handle mounting cavity 21 through the insertion port 22 of the base 20, and inserted all the way forward, as shown. Figure 19b As shown;

[0096] S3, such as Figure 19b As shown, adjust the position of the handle insertion part 32 in the handle mounting cavity 21 so that the handle insertion part 32 moves to the left towards the seat step part 24. Then, the seat step part 24 initially engages with the handle engagement area 37 on the outer periphery of the handle insertion part 32, and the handle step part 33 initially engages with the seat engagement area 26 within the base 20. The seat step part 24 is distributed on the rear side of the handle step part 33, as shown. Figure 19c As shown;

[0097] S4, such as Figure 19d As shown, screw the first fastener 40 into the locking hole 23 of the base 20 to the left until the first fastener 40 is tightened, as shown. Figure 19eAs shown, the door and window handle 30 is fixedly installed in the base 20. During the tightening process of the first fastener 40, the first fastener 40 is initially in close contact with the handle insertion part 32. Then, as the first fastener 40 is continuously tightened, the handle insertion part 32 contacts and is in close contact with the seat step part 24. Finally, after the first fastener 40 is tightened, the first fastener 40, the handle insertion part 32 and the seat step part 24 are in close contact with each other.

[0098] After tightening the first fastener 40, as Figure 7 and Figure 19e As shown, the seat step portion 24 is fitted into the handle fitting area 37, and the handle step portion 33 is fitted into the seat fitting area 26. In the insertion direction of the handle insertion portion 32, the handle body 31 is tightly pressed against the rear side of the base 20, while the seat step portion 24 is tightly distributed next to the rear side of the handle step portion 33, achieving locking in the front-back direction and restricting the front-back movement of the handle insertion portion 32, thereby restricting the handle insertion portion 32 from moving backward in the opposite direction of its insertion direction and preventing the handle insertion portion 32 from coming out of the base 20. In the screwing direction of the first fastener 40, the first fastener 40 is tightly pressed against the right side of the handle insertion portion 32, and the handle insertion portion 32 is tightly pressed against the right side of the seat step portion 24, locking in the left-right direction and restricting the relative movement between the handle insertion portion 32 and the base 20 in the screwing direction of the first fastener 40, so that the door and window handle 30 can better withstand a large pushing and pulling force, improving the tensile and compressive strength of the door and window handle 30.

[0099] Therefore, the handle mounting structure of this application, while effectively fixing the door / window handle 30 to the base 20, can withstand relatively large pushing and pulling forces and has good structural strength, making it well-suited for large sliding doors and windows. Furthermore, the handle mounting structure of this application requires only three types of components: the base 20, the door / window handle 30, and the first fastener 40. This reduces the number of required components, resulting in a simple, reliable, and easily implemented overall structure, effectively lowering costs.

[0100] In the above-described handle mounting structure, the insertion direction of the handle insertion part 32 is forward, and the screwing direction of the first fastener 40 is leftward. Therefore, the insertion direction of the handle insertion part 32 is perpendicular to the screwing direction of the first fastener 40. When the first fastener 40 is tightened on the base 20, as... Figure 7As shown, the left section of the first fastener 40 extends to the left from the locking hole 23 and is located in the handle mounting cavity 21. This section of the first fastener 40 extending to the left from the locking hole 23 is defined as the fastening extension section 41. Specifically, the outer periphery of the left end of the fastening extension section 41 is provided with a locking conical surface 42, the outer diameter of which gradually decreases from right to left. The fastening extension section 41 is inclined forward and to the right at the lower end of the locking conical surface 42. The right side surface of the handle insertion part 32 is provided with a locking inclined surface 321, which is also inclined forward and to the right. The inclination of the locking conical surface 42 is equal to that of the locking inclined surface 321. In this embodiment, the inclination of both the locking conical surface 42 and the locking inclined surface 321 is 40° to 50°, and is particularly preferably 45°.

[0101] During the process of screwing the first fastener 40 into the base 20 to the left through the locking hole 23, as Figure 7 As shown, the fastening extension 41 extends to the left in the direction of approaching the handle insertion part 32 until the locking conical surface 42 on the first fastener 40 contacts and engages with the locking inclined surface 321 on the outer periphery of the handle insertion part 32. The locking inclined surface 321 is distributed on the front side of the fastening extension 41 away from the handle body 31, that is, the locking conical surface 42 abuts against the rear side of the locking inclined surface 321. Subsequently, as the first fastener 40 continues to be screwed in to the left, the fastening extension 41 continues to extend to the left from the locking hole 23. Through the surface contact and engagement of the locking conical surface 42 and the locking inclined surface 321, the first fastener 40 presses the handle insertion part 32 forward and to the left. This drives the handle insertion part 32 to move to the left towards the seat step part 24, allowing the handle insertion part 32 to better fit against the right side of the seat step part 24. Simultaneously, it also drives the handle insertion part 32 to move forward along its insertion direction, causing the handle body 31 to move further forward towards the base 20, ultimately allowing the handle body 31 to better fit against the rear side of the base 20. Finally, the first fastener 40 is tightened in the base 20. At this point, as... Figure 7As shown, the locking conical surface 42 at the left end of the first fastener 40 and the locking inclined surface 321 on the right side of the handle insertion part 32 are in surface contact and tightly fitted. Then, the first fastener 40 applies a force F to the handle insertion part 32 at the contact point between the locking conical surface 42 and the locking inclined surface 321. This force F is perpendicular to the locking inclined surface 321 on the right side of the handle insertion part 32. Thus, the force F applied by the first fastener 40 to the handle insertion portion 32 has a first component F1 in the screwing direction of the first fastener 40 and a second component F2 in the insertion direction of the handle insertion portion 32. The direction of the first component F1 is the same as the screwing direction of the first fastener 40, both pointing to the left, thereby making the first fastener 40, the handle insertion portion 32, and the seat step portion 24 more reliably fit together in the screwing direction of the first fastener 40. The direction of the second component F2 is the same as the insertion direction of the handle insertion portion 32, both pointing forward, thereby making the handle body 31 and the base 20 more reliably fit together in the insertion direction of the handle insertion portion 32. Therefore, by setting the locking conical surface 42 at the left end of the first fastener 40 and the locking inclined surface 321 on the right side of the handle insertion portion 32, the overall strength of the handle mounting structure is more reliably guaranteed, making it better suited for large sliding doors and windows. Furthermore, based on the tight fit between the handle body 31 and the base 20 in the front-back direction, and the tight fit between the first fastener 40, the handle insertion part 32 and the seat step part 24 in the left-right direction, the movement of the handle insertion part 32 in the front-back direction and the left-right direction is restricted, so that the handle insertion part 32 is completely positioned in these two directions.

[0102] Furthermore, in this embodiment, as Figures 9 to 12 As shown, the handle mounting cavity 21 in the base 20 is roughly a square chamber, and the handle mounting cavity 21 has a through-slot structure that runs from front to back. Figures 13 to 16 As shown, the handle insertion portion 32 on the door / window handle 30 is generally a square column. Preferably, the outline dimensions of the insertion port 22 and the handle mounting cavity 21 are both larger than the outline dimension of the handle insertion portion 32. Therefore, when the handle insertion portion 32 is inserted forward into the handle mounting cavity 21 through the insertion port 22, as... Figure 6 and Figure 8 As shown, there is a movable gap between the handle insertion part 32 and the cavity wall of the handle mounting cavity 21, which facilitates the insertion of the handle insertion part 32 forward into the handle mounting cavity 21, and also allows the handle insertion part 32 to move to the left after being inserted into the handle mounting cavity 21. In this embodiment, in the vertical direction, the width of the insertion port 22 and the width of the handle mounting cavity 21 are slightly larger than the width of the handle insertion part 32, which reduces the vertical offset of the handle insertion part 32 during the installation process while allowing the handle insertion part 32 to be inserted forward. In addition, as Figure 14 , Figure 19a and Figure 19bAs shown, the right side surface of the handle insertion part 32 is a guide slope 324 that slopes to the left and forward, and the front end of the handle insertion part 32 is a mounting chamfer 325; the guide slope 324 and the mounting chamfer 325 make it easier for the handle insertion part 32 to be inserted forward into the handle mounting cavity 21.

[0103] Furthermore, such as Figure 13 and Figure 14 As shown, along the extending direction of the first fastener 40, the handle insertion part 32 has a limiting locking groove 322 on its right side surface facing the first fastener 40, while the handle step part 33 is provided on the left side surface of the handle insertion part 32 facing away from the first fastener 40. Thus, the limiting locking groove 322 and the handle step part 33 are provided on a pair of opposing surfaces of the handle insertion part 32. The limiting locking groove 322 is approximately square, with its left end being its bottom. The locking inclined surface 321 of the handle insertion part 32 is the front wall surface of the limiting locking groove 322. Along a direction perpendicular to both the insertion direction of the handle insertion part 32 and the screwing direction of the first fastener 40, i.e., along the vertical direction, the upper and lower wall surfaces of the limiting locking groove 322 form a pair of limiting surfaces 323, distributed on the upper and lower sides of the fastening extension section 41. When the first fastener 40 is tightened in the base 20, as... Figure 8 As shown, the upper and lower sides of the fastening extension section 41 are exactly in close contact with a pair of limiting surfaces 323, locking in the vertical direction, thereby restricting the vertical movement between the handle insertion part 32 and the first fastener 40 in a direction perpendicular to both the insertion direction of the handle insertion part 32 and the screwing direction of the first fastener 40. This also restricts the vertical movement of the door and window handle 30 relative to the base 20 in this direction, making the door and window handle 30 more reliably fixed in the base 20.

[0104] Preferably, such as Figure 13 and Figure 14 As shown, the limiting surfaces 323 on both the upper and lower sides of the limiting locking groove 322 are inclined surfaces. The limiting surfaces 323 are inclined in a way that they are further away from the left bottom of the limiting locking groove 322 and further away from the fastening extension section 41. Therefore, the distance between a pair of limiting surfaces 323 gradually increases in the direction away from the bottom of the limiting locking groove 322, making the limiting locking groove 322 roughly a flared structure. The right side of the limiting locking groove 322 has the largest opening, which makes it convenient for the first fastener 40 to extend to the left into the limiting locking groove 322, and also facilitates the tightening operation of the first fastener 40.

[0105] Preferably, such as Figure 6 and Figure 7As shown, the first fastener 40 is a countersunk screw, and the locking hole 23 is a threaded hole for screwing into the fastener. With this structure, the head on the right side of the first fastener 40 is recessed into the locking hole 23 and will not protrude from the right side of the base 20, resulting in a better overall appearance for the handle mounting structure and improving the overall aesthetics of the sliding door and window.

[0106] Furthermore, the preferred structure of the handle body 31 is as follows: Figure 13 and Figure 15 As shown, the handle body 31 includes a grip portion 311 extending vertically and two vertically symmetrical bent connecting portions 312. The two bent connecting portions 312 are fixed at the upper and lower ends along the length of the grip portion 311. The bent connecting portions 312 extend from the end of the grip portion 311 in a direction away from the grip portion 311 and close to the base 20, bending forward and to the left. Figure 4 and Figure 5 As shown, there are two pedestals 20, arranged symmetrically vertically. Each pedestal 20 is located at the front end of the handle body 31, away from the grip portion 311, where each bent connecting portion 312 is positioned. The handle insertion portion 32 extends forward integrally from the front surface of each bent connecting portion 312 facing the pedestal 20. Thus, a gripping area is formed between the grip portion 311 and the vertical profile 101 of the sash frame in the handle body 31, facilitating user gripping of the handle body 31. Simultaneously, the handle mounting structure is symmetrical vertically, resulting in balanced overall force distribution and improved performance against large pushing and pulling forces, making it better suited for large sliding doors and windows. Preferably, as... Figure 13 and Figure 15 As shown, the grip portion 311 of the handle body 31 has a smooth surface, and it has rounded transition surfaces on both the left and right sides in the width direction to avoid the surface of the grip portion 311 having abrupt edges, thereby improving the user's gripping feel when holding the door and window handle 30.

[0107] Preferably, the door and window handle 30 is an integral component, which gives the door and window handle 30 good structural strength and the ability to withstand greater pushing and pulling forces, thus making it more suitable for large sliding doors and windows.

[0108] Furthermore, such as Figure 7 ,as well as Figures 13 to 16As shown, the bent connecting portion 312 of the handle body 31 directly abuts against the rear side of the base 20. The handle body 31 has two reference surfaces: the front end face of the bent connecting portion 312 facing the base 20 and the left end face of the handle insertion portion 32 facing the seat step portion 24. The front end face of the bent connecting portion 312 facing the base 20 constitutes the first reference surface 34 of the handle body 31, which is a vertical plane in the left-right direction. The left end face of the handle insertion portion 32 facing the seat step portion 24 constitutes the second reference surface 35 of the handle body 31, which is a vertical plane in the front-back direction. The handle step portion 33 is distributed on the front side of the second reference surface 35 along the insertion direction of the handle insertion portion 32. At the same time, the first reference surface 34 and the second reference surface 35 are perpendicular. When the first fastener 40 is tightened in the base 20, the first reference surface 34 contacts and engages with the rear surface of the base 20, and the second reference surface 35 abuts against the seat step portion 24 of the base 20. By setting a first reference surface 34 and a second reference surface 35 that are perpendicular to each other on the door and window handle 30, the machining accuracy of the door and window handle 30 is improved, which also improves the reliability of the door and window handle 30 and the base 20 in the front-back direction and the left-right direction, so that the door and window handle 30 is more reliably fixed in the base 20, and further improves its ability to withstand greater push and pull forces.

[0109] Preferably, such as Figure 7 and Figure 12 As shown, the seat step portion 24 has a first arcuate curved surface 25 at the right front end near the handle step portion 33, so that the base 20 has a smooth surface at the right front end of the seat step portion 24; as Figure 7 and Figure 16 As shown, the handle step portion 33 has a second arcuate curved surface 36 at the left rear end near the seat step portion 24, so that the door and window handle 30 has a smooth surface at the left rear end of the handle step portion 33; when the first fastener 40 is tightened in the base 20, as Figure 7 As shown, the second arcuate surface 36 is close to the front side of the first arcuate surface 25, but the second arcuate surface 36 and the first arcuate surface 25 are not tightly attached and there is a gap between them. In this way, by having the seat step portion 24 close to the rear side of the handle step portion 33, the rearward movement of the handle step portion 33 can be restricted, preventing the handle step portion 33 from dislodging from the base 20. At the same time, by setting the gap between the second arcuate surface 36 and the first arcuate surface 25, it can be reliably ensured that after the first fastener 40 is tightened, the first reference surface 34 is in close contact with the rear surface of the base 20, and the second reference surface 35 is in close contact with the right surface of the seat step portion 24 in the base 20. That is, interference with the installation of the door and window handle 30 is avoided, and it is ensured that the outer edge of the door and window handle 30 at the base 20 is flush with the outer edge of the base 20.

[0110] Preferably, the radius of the first arcuate surface 25 on the seat step 24 is larger than the radius of the second arcuate surface 36 on the handle step 33. In this embodiment, the radius of the first arcuate surface 25 on the seat step 24 is approximately twice the radius of the second arcuate surface 36 on the handle step 33. Preferably, the radius of the first arcuate surface 25 is 1 mm, and the radius of the second arcuate surface 36 is 0.5 mm. This allows the base 20 to have a larger empty area on the outer periphery of the first arcuate surface 25, making it easier for the handle step 33 to enter the seat fitting area 26.

[0111] Furthermore, the preferred fixing structure of the pedestal 20 on the vertical profile 101 of the door / window sash frame 10 is as follows: Figure 17 and Figure 18 As shown, each base 20 is fixedly connected to the door and window frame 10 by two second fasteners 80. The two second fasteners 80 are distributed on the upper and lower sides of the handle mounting cavity 21 to avoid interference with the second fasteners 80.

[0112] Preferably, such as Figure 17 and Figure 18 As shown, the second fastener 80 is a countersunk screw. The second fastener 80 is screwed forward into the base 20 and the vertical profile 101 of the sash frame, and the head of the second fastener 80 at the rear end is recessed into the base 20 and will not protrude from the base 20. At the same time, the outline dimensions of the base 20 are the same as the outline dimensions of the handle body 31 at the front end of the bent connection 312. After the handle body 31 is fixed in the base 20, the outer peripheral surface of the handle body 31 at the front end of the bent connection 312 is aligned with the outer peripheral surface of the base 20. Then, the front end surface of the handle body 31 at the front end of the bent connection 312 covers the second fastener 80, improving the appearance of the sliding door and window.

[0113] Preferably, such as Figure 3 ,as well as Figure 17 and Figure 18As shown, the sliding door / window sash 60 also has an installation accessory 90 at the handle mounting structure. The installation accessory 90 is inserted into the profile cavity of the sash frame vertical profile 101. The sash frame vertical profile 101 has profile fixing parts 103 distributed in the front-rear direction between the base 20 and the installation accessory 90. The base 20 is fixedly connected to the installation accessory 90 by a second fastener 80. At the same time, the installation accessory 90 is also fixedly connected to the profile fixing part 103 by a third fastener 110, thereby fixing the base 20 to the rear surface of the sash frame vertical profile 101. The third fastener 110 is also a countersunk screw, distributed between the two second fasteners 80. Based on this structure, the base 20 needs to be machined with threaded holes for screwing into the second fastener 80, and the mounting accessory 90 needs to be machined with threaded holes for screwing into the second fastener 80 and the third fastener 110. The fan frame vertical profile 101 only needs to be machined with through holes for the second fastener 80 to pass through and countersunk holes to accommodate the head of the third fastener 110, thus reducing the difficulty of drilling on the fan frame vertical profile 101 and facilitating production. Furthermore, as... Figure 10 and Figure 12 As shown, the front end face of the base 20 is provided with a threaded extension section 27 that protrudes forward and is screwed to the second fastener 80, which increases the screwing strength between the base 20 and the second fastener 80. The threaded extension section 27 is inserted into the through hole of the fan frame vertical profile 101 for the second fastener 80 to pass through.

[0114] In summary, the handle mounting structure described above involves only three types of components: the base 20, the door / window handle 30, and the first fastener 40. There are two bases 20, one door / window handle 30, and two first fasteners 40, totaling five components across three types. By using a large handle suitable for large sliding doors and windows, this application effectively reduces costs. After the door / window handle 30 is fixed in the base 20, it is completely restricted in the vertical, horizontal, and front-back directions, achieving perfect positioning and high strength. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial applicability.

[0115] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
