[0086] As shown in Figure 4 and Figure 5 , and Figures 13 to 16 , the door and window handle 30 comprises a handle body 31, a handle insertion portion 32 and a handle step portion 33; the handle body 31 is used for a user to hold and push or pull the door and window sash 60; the handle insertion portion 32 is fixed on the front end surface of the handle body 31 facing the pedestal 20, that is, the handle insertion portion 32 protrudes and extends forwardly from the front end surface of the handle body 31 towards the pedestal 20; the handle step portion 33 protrudes leftward from the left side surface of the handle insertion portion 32, and then the left side of the handle insertion portion 32 is formed with a handle fitting area 37 in the rear of the handle step portion 33, and the handle fitting area 37 is the peripheral empty area of the handle insertion portion 32.

[0087] When the pedestal 20 and the door and window handle 30 are fixed, the handle insertion portion 32 is first inserted into the handle mounting cavity 21 inwardly (i.e. forwardly) through the insertion opening 22, and then the first fastener 40 is screwed into the locking hole 23 from the right side of the pedestal 20 leftward, and then the insertion direction of the handle insertion portion 32 into the pedestal 20 is the forward direction, and the screwing direction of the first fastener 40 is the left direction. When the handle insertion portion 32 is inserted into the handle mounting cavity 21 forwardly through the insertion opening 22, and the first fastener 40 is screwed into the pedestal 20 leftward through the locking hole 23 and is tightened, as shown in Figure 6 and Figure 7As shown, along the screwing direction of the first fastener 40 into the base 20, the first fastener 40, the handle insertion portion 32 and the seat step portion 24 are tightly attached to each other from right to left; along the insertion direction of the handle insertion portion 32 inward (i.e., forward) 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, while the seat step portion 24 is distributed on the outside (i.e., the rear side) of the handle step portion 33, or in other words, there is a very small gap between the front end of the seat step portion 24 and the rear end of the handle step portion 33, so that the seat step portion 24 and the handle step portion 33 do not contact in the front-to-back direction, but are very close, and the two are arranged adjacent to each other.

[0088] Furthermore, the present application also provides a handle installation method of the handle installation structure, which comprises the following steps in sequence:

[0089] S1, such as Figure 17 As shown, the pedestal 20 is fixed to the preset installation position of the door and window sash frame 10 of the sliding door and window;

[0090] S2, such as Figure 19a As shown, the handle insertion portion 32 of the door and window handle 30 is inserted forward into the handle installation cavity 21 through the insertion opening 22 of the pedestal 20 and inserted forward to the bottom, as shown in FIG. Figure 19b As shown;

[0091] S3, such as Figure 19b As shown, the position of the handle insert portion 32 in the handle mounting cavity 21 is adjusted so that the handle insert portion 32 moves leftward toward the seat step portion 24. Then, the seat step portion 24 is initially fitted into the handle fitting area 37 on the outer periphery of the handle insert portion 32, and the handle step portion 33 is initially fitted into the seat fitting area 26 in the pedestal 20. The seat step portion 24 is distributed on the rear side of the handle step portion 33, as shown in FIG. Figure 19c As shown;

[0092] S4, such as Figure 19d As shown, the first fastener 40 is screwed leftward into the locking hole 23 of the base 20 until the first fastener 40 is tightened. Figure 19e As shown, the door and window handle 30 is fixedly installed in the pedestal 20. During the tightening process of the first fastener 40, the first fastener 40 initially abuts against the handle insert 32. Then, as the first fastener 40 is continuously screwed in, the handle insert 32 contacts and abuts against the seat step 24. Finally, after the first fastener 40 is tightened, the first fastener 40, the handle insert 32, and the seat step 24 abut against each other.

[0093] After the first fastener 40 is tightened, Figure 7 and Figure 19eAs shown, the seat step portion 24 is fitted in the handle fitting area 37, and the handle step portion 33 is fitted in the seat fitting area 26. In the insertion direction of the handle insertion portion 32, the handle body 31 abuts against the rear side of the seat 20, and the seat step portion 24 abuts against the rear side of the handle step portion 33, thereby achieving locking in the front-rear direction, limiting the front-rear movement of the handle insertion portion 32, and thereby limiting the rearward movement of the handle insertion portion 32 in the direction opposite to its insertion direction, avoiding the rearward disengagement of the handle insertion portion 32 from the seat 20. In the screwing direction of the first fastener 40, the first fastener 40 abuts against the right side of the handle insertion portion 32, and the handle insertion portion 32 abuts against the right side of the seat step portion 24, thereby achieving locking in the left-right direction, limiting the relative movement between the handle insertion portion 32 and the seat 20 in the screwing direction of the first fastener 40, and thereby enabling the door and window handle 30 to better withstand a larger pulling force, and improving the strength of the door and window handle 30 against the pulling force and the compression force.

[0094] Therefore, the handle mounting structure according to the present application can better withstand a larger pulling force and has a better structural strength under the premise of fixing the door and window handle 30 to the seat 20, and can be better applied to large sliding doors and windows. Meanwhile, the handle mounting structure according to the present application only needs three types of components, i.e., the seat 20, the door and window handle 30, and the first fastener 40, has a small number of required components, and has a simple and reliable overall structure, which is easy to implement and can effectively reduce the cost.

[0095] In the above handle mounting structure, the insertion direction of the handle insertion portion 32 is the front direction, and the screwing direction of the first fastener 40 is the left direction, so the insertion direction of the handle insertion portion 32 is perpendicular to the screwing direction of the first fastener 40. When the first fastener 40 is screwed in the seat 20, Figure 7 As shown, the left segment of the first fastener 40 extends leftward from the locking hole 23 and is located in the handle mounting cavity 21, and this segment of the first fastener 40 extending leftward from the locking hole 23 is defined as the fastening extension segment 41. In particular, the outer periphery of the left end of the fastening extension segment 41 is provided with a locking conical surface 42, the outer diameter of the locking conical surface 42 gradually decreases from right to left, and the fastening extension segment 41 is inclined forward and rightward at the lower end of the locking conical surface 42; and the right side surface of the handle insertion portion 32 is provided with a locking inclined surface 321, the locking inclined surface 321 is also inclined forward and rightward, and the inclination of the locking conical surface 42 is equal to the inclination of the locking inclined surface 321. In the present embodiment, the inclination of the locking conical surface 42 and the inclination of the locking inclined surface 321 are both 40°-50°, and are particularly preferably 45°.

[0096] In the process of screwing the first fastener 40 leftward into the seat 20 through the locking hole 23, Figure 7As shown, the fastening extension section 41 extends to the left in the direction close to the handle insertion portion 32 until the locking conical surface 42 on the first fastener 40 contacts and cooperates with the locking inclined surface 321 on the outer periphery of the handle insertion portion 32, and the locking inclined surface 321 is distributed on the front side of the fastening extension section 41 facing away from the handle body 31, that is, the locking conical surface 42 abuts against the rear side of the locking inclined surface 321. Afterwards, as the first fastener 40 continues to be screwed in to the left, the fastening extension section 41 continues to extend to the left from the locking hole 23. Then, through the surface contact between the locking conical surface 42 and the locking inclined surface 321, the first fastener 40 presses the handle insertion portion 32 toward the left front. On the one hand, it drives the handle insertion portion 32 to move horizontally to the left toward the seat step portion 24, so that the handle insertion portion 32 is better fitted to the right side of the seat step portion 24; on the other hand, it also drives the handle insertion portion 32 to move forward along its insertion direction, which also makes the handle body 31 as a whole move further forward toward the base 20, and finally makes the handle body 31 better fit to the rear side of the base 20. Finally, the first fastener 40 is tightened in the base 20. At this time, as shown in FIG. Figure 7 As shown, the locking conical surface 42 at the left end of the first fastener 40 is in surface contact with and tightly attached to the locking inclined surface 321 on the right side of the handle insertion portion 32. The first fastener 40 applies a force F to the handle insertion portion 32 at the contact point between the locking conical surface 42 and the locking inclined surface 321. The force F is perpendicular to the locking inclined surface 321 on the right side of the handle insertion portion 32. In this way, the force F exerted by the first fastener 40 on 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 facing leftward, thereby ensuring that the first fastener 40, the handle insertion portion 32, and the seat step portion 24 are more securely attached 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 facing forward, thereby ensuring that the handle body 31 and the base 20 are more securely attached in the insertion direction of the handle insertion portion 32. Therefore, by providing the locking conical surface 42 on 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 ensured, making it more suitable for large sliding doors and windows. In addition, based on the close contact between the handle body 31 and the base 20 in the front-to-back direction, and the close contact between the first fastener 40, the handle insertion portion 32 and the base step portion 24 in the left-to-right direction, the movement of the handle insertion portion 32 in the front-to-back direction and the left-to-right direction is restricted, so that the handle insertion portion 32 is completely positioned in these two directions.

[0097] Furthermore, in this embodiment, if Figures 9 to 12 As shown, the handle mounting cavity 21 in the base 20 is substantially a square cavity, and the handle mounting cavity 21 is a through-groove structure that passes through from front to back. Figures 13 to 16As shown, the handle insertion part 32 of the door and window handle 30 is substantially a square column. Preferably, the profile size of the insertion opening 22 and the profile size of the handle mounting cavity 21 are both larger than the profile size of the handle insertion part 32, then when the handle insertion part 32 is inserted into the handle mounting cavity 21 through the insertion opening 22, as shown in Figure 6 and Figure 8 shown, there is a clearance between the handle insertion part 32 and the cavity wall surface of the handle mounting cavity 21, which facilitates the insertion operation of the handle insertion part 32 into the handle mounting cavity 21 and allows the handle insertion part 32 to be translated leftward after being inserted into the handle mounting cavity 21. In the present embodiment, in the up-down direction, the width of the insertion opening 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 up-down deviation of the handle insertion part 32 during the installation process on the premise of allowing the handle insertion part 32 to be inserted forward. In addition, as shown in Figure 14 , Figure 19a and Figure 19b shown, the right side surface of the handle insertion part 32 is a leftward and forward inclined guide slope 324, and the front end of the handle insertion part 32 is a mounting chamfer part 325; the arrangement of the guide slope 324 and the mounting chamfer part 325 makes the handle insertion part 32 more easily inserted forward into the handle mounting cavity 21.

[0098] Further, as shown in Figure 13 and Figure 14 shown, along the extension direction of the first fastener 40, a limit locking groove 322 is arranged on the right side surface of the handle insertion part 32 facing the first fastener 40, and the handle step part 33 is arranged on the left side surface of the handle insertion part 32 away from the first fastener 40, then the limit locking groove 322 and the handle step part 33 are arranged on a pair of opposite surfaces of the handle insertion part 32. The limit locking groove 322 is substantially a square groove, the left end of the limit locking groove 322 is its groove bottom, and the locking inclined surface 321 of the handle insertion part 32 is the front side groove wall surface of the limit locking groove 322. Along the 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 up-down direction, the upper side groove wall surface and the lower side groove wall surface of the limit locking groove 322 are a pair of limit surfaces 323, and the pair of limit surfaces 323 are distributed on the up-down two sides of the fastening protruding section 41. When the first fastener 40 is tightened in the pedestal 20, as shown in Figure 8 shown, the up-down two sides of the fastening protruding section 41 are in close contact with the pair of limit surfaces 323, and are locked in the up-down direction, thereby limiting the up-down movement between the handle insertion part 32 and the first fastener 40 in the direction perpendicular to both the insertion direction of the handle insertion part 32 and the screwing direction of the first fastener 40, and also limiting the up-down movement of the door and window handle 30 relative to the pedestal 20 in the direction, so that the door and window handle 30 is more reliably fixed and installed in the pedestal 20.

[0099] Preferably, as shown in Figure 13 andFigure 14 As shown, the limiting surfaces 323 on the upper and lower sides of the limiting locking groove 322 are both inclined surfaces, and the limiting surfaces 323 are inclined in such a way that the further away from the left bottom of the limiting locking groove 322 and the further away from the fastening extension section 41, the spacing between a pair of limiting surfaces 323 gradually increases in the direction away from the bottom of the limiting locking groove 322, so that the limiting locking groove 322 is roughly a trumpet-mouth structure, and the right side opening of the limiting locking groove 322 is the largest, which facilitates the first fastener 40 to extend to the left into the limiting locking groove 322, thereby facilitating the tightening operation of the first fastener 40.

[0100] Preferably, if Figure 6 and Figure 7 As shown, the first fastener 40 is a countersunk screw, and the locking hole 23 is a threaded hole that is threaded with the fastener. With this structure, the right head of the first fastener 40 is sunken into the locking hole 23 and does not protrude to the right from the right side of the base 20, giving the handle mounting structure a better appearance and enhancing the overall aesthetics of the sliding door and window.

[0101] 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 gripping portion 311 extending vertically, and two symmetrical bent connecting portions 312. The two bent connecting portions 312 are fixed at the upper and lower ends of the gripping portion 311 in the longitudinal direction. The bent connecting portion 312 bends and extends from the end of the gripping portion 311 to the left front in a direction away from the gripping portion 311 and close to the base 20. Figure 4 and Figure 5 As shown, there are two pedestals 20, which are symmetrically arranged up and down. The two pedestals 20 are respectively arranged at the front end of each bent connection part 312 in the handle body 31 away from the gripping part 311, and the handle insertion part 32 extends forward from the front end surface of each bent connection part 312 facing the pedestal 20. In this way, the handle body 31 forms a gripping area between the gripping part 311 and the sash frame vertical profile 101, which is convenient for the user to grip the handle body 31. At the same time, the handle installation structure is a symmetrical structure up and down, and the overall force is balanced, which improves its overall performance of withstanding large push-pull forces and is better suitable for large sliding doors and windows. Preferably, as Figure 13 and Figure 15 As shown, the gripping portion 311 of the handle body 31 has a smooth surface, and arc transition surfaces are provided on both sides of the width direction to avoid abrupt edges on the surface of the gripping portion 311, thereby improving the user's feel when holding the door and window handle 30.

[0102] Preferably, the door and window handle 30 is an integrated component, so that the door and window handle 30 itself has good structural strength and can withstand large push and pull forces, thereby being better suitable for large sliding doors and windows.

[0103] Further, as shown in Figure 7 , and Figures 13 to 16 , the bent connecting part 312 of the handle body 31 directly abuts against the rear side of the seat 20; the handle body 31 has two reference surfaces, which are respectively the front end surface of the bent connecting part 312 facing the seat 20 and the left end surface of the handle insertion part 32 facing the seat step part 24. The front end surface of the bent connecting part 312 facing the seat 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 surface of the handle insertion part 32 facing the seat step part 24 constitutes the second reference surface 35 of the handle body 31, which is a vertical plane in the front-rear direction, and the handle step part 33 is distributed on the front side of the second reference surface 35 along the insertion direction of the handle insertion part 32; at the same time, the first reference surface 34 is perpendicular to the second reference surface 35. When the first fastener 40 is tightened in the seat 20, the first reference surface 34 is in surface contact with the rear surface of the seat 20, and the second reference surface 35 abuts against the seat step part 24 of the seat 20. By providing the first reference surface 34 and the second reference surface 35 perpendicular to each other on the door and window handle 30, the machining precision of the door and window handle 30 is improved, the reliability of the door and window handle 30 tightly abutting against the seat 20 in the front-rear direction and the left-right direction is improved, the door and window handle 30 is more reliably fixed and installed in the seat 20, and the ability of the door and window handle 30 to withstand a larger pulling force is further improved.

[0104] Preferably, as shown in Figure 7 and Figure 12 , the seat step part 24 is provided with a first arc curved surface 25 at the right front end part close to the handle step part 33, so that the seat 20 has a smooth surface at the right front end of the seat step part 24; as shown in Figure 7 and Figure 16 , the handle step part 33 is provided with a second arc curved surface 36 at the left rear end part close to the seat step part 24, so that the door and window handle 30 has a smooth surface at the left rear end of the handle step part 33; as shown in Figure 7 , the second arc curved surface 36 is immediately on the front side of the first arc curved surface 25 after the first fastener 40 is tightened in the seat 20, but the second arc curved surface 36 and the first arc curved surface 25 are not tightly abutting and have a gap therebetween. In this way, by abutting the seat step part 24 against the rear side of the handle step part 33, the rear movement of the handle step part 33 is limited, and the handle step part 33 is prevented from being detached rearward from the seat 20; at the same time, by the gap between the second arc curved surface 36 and the first arc curved surface 25, it is reliably ensured that the first reference surface 34 tightly abuts against the rear surface of the seat 20 and the second reference surface 35 tightly abuts against the right surface of the seat step part 24 of the seat 20 after the first fastener 40 is tightened, that is, interference with the installation of the door and window handle 30 is avoided, and it is ensured that the appearance edge of the door and window handle 30 at the seat 20 is flush with the appearance edge of the seat 20.

[0105] Preferably, the radius of the first circular arc surface 25 on the seat step portion 24 is greater than the radius of the second circular arc surface 36 on the handle step portion 33; in the present embodiment, the radius of the first circular arc surface 25 on the seat step portion 24 is about 2 times the radius of the second circular arc surface 36 on the handle step portion 33, preferably the radius of the first circular arc surface 25 is 1 mm and the radius of the second circular arc surface 36 is 0.5 mm. In this way, the seat 20 has a larger empty area on the outer periphery side of the first circular arc surface 25, so that the handle step portion 33 can more easily enter the seat fitting area 26.

[0106] Further, the fixing structure of the seat 20 on the sash vertical profile 101 of the door and window sash frame 10 is preferably as shown in Figure 17 and Figure 18 , each seat 20 is fixedly connected with the door and window sash frame 10 by two second fasteners 80, which are distributed on the upper and lower sides of the handle mounting cavity 21 to avoid interference with the second fasteners 80.

[0107] Preferably, as shown in Figure 17 , and Figure 18 , the second fastener 80 is a fastening screw, which is a countersunk screw, the second fastener 80 is screwed forward into the seat 20 and the sash vertical profile 101, and the head of the rear end of the second fastener 80 is sunk into the seat 20 and does not protrude backward from the seat 20; at the same time, the contour size of the seat 20 is the same as the contour size of the handle body 31 at the front end of the bent connecting portion 312, after the handle body 31 is fixed in the seat 20, the outer peripheral surface of the handle body 31 at the front end of the bent connecting portion 312 is aligned with the outer peripheral surface of the seat 20, so that the front end surface of the handle body 31 at the front end of the bent connecting portion 312 covers the second fastener 80, improving the appearance of the sliding door and window.

[0108] Preferably, as shown in Figure 3 , and Figure 17 and Figure 18As shown, the sliding door and window sash 60 is also provided with a mounting auxiliary material 90 at the handle mounting structure, the mounting auxiliary material 90 is inserted in the profile cavity of the sash vertical profile 101, the sash vertical profile 101 has a profile fixed part 103 distributed between the pedestal 20 and the mounting auxiliary material 90 in the front and rear direction, the pedestal 20 is fixedly connected with the mounting auxiliary material 90 through the second fastener 80, and at the same time, the mounting auxiliary material 90 is also fixedly connected with the profile fixed part 103 through the third fastener 110, so as to fix the pedestal 20 on the rear surface of the sash vertical profile 101. The third fastener 110 is also a countersunk screw, which is distributed between the two second fasteners 80. Based on the structure, the threaded hole for screwing with the second fastener 80 needs to be machined on the pedestal 20, the threaded hole for screwing with the second fastener 80 and the third fastener 110 needs to be machined on the mounting auxiliary material 90, and only the through hole for the second fastener 80 and the counterbore for accommodating the head of the third fastener 110 need to be machined on the sash vertical profile 101, thereby reducing the difficulty of drilling on the sash vertical profile 101 and facilitating production and processing. In addition, as shown in Figure 10 and Figure 12 the front end face of the pedestal 20 is provided with a threaded extension 27 protruding forward and screwed with the second fastener 80, which increases the screwing strength between the pedestal 20 and the second fastener 80, and the threaded extension 27 is inserted in the through hole of the sash vertical profile 101 for the second fastener 80.

[0109] In summary, the handle mounting structure with the above structure only involves three types of parts, i.e. the pedestal 20, the door and window handle 30 and the first fastener 40, there are two pedestals 20, one door and window handle 30 and two first fasteners 40, which are three types and five in total, and under the premise of adopting a large handle suitable for a large sliding door and window, the application effectively reduces the cost. After the door and window handle 30 is fixed in the pedestal 20, the door and window handle 30 is completely positioned and has high strength in all directions of up and down, left and right, and front and rear. Therefore, the utility model effectively overcomes the various shortcomings in the prior art and has high industrial utilization value.
