The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] It is understandable that, referring to Figures 1 to 9The present invention provides a door and window handle, comprising a mounting base 100, a handle 200 and a positioning assembly 300. The mounting base 100 is provided with a through hole 110 and a mounting groove 120, the through hole 110 being connected to the mounting groove 120; the handle 200 is provided with a connecting portion 210, the connecting portion 210 can pass through the through hole 110 and extend into the mounting groove 120, the end of the connecting portion 210 is provided with a square groove 211 for clamping a square shaft, and the handle 200 can abut against the mounting base 100; the positioning assembly 300 is provided with a through hole 110 and a mounting groove 120, and the through hole 110 is connected to the mounting groove 120; the through hole 110 is connected to the ... through hole 110 is connected to the mounting groove 120; the through hole 110 is connected to the mounting groove 120, and the through hole 110 is connected to the mounting groove 120; the through hole 110 is connected to the mounting groove 120, and the through hole 110 is connected to the mounting groove 120; the through 0 includes a rotating wheel 310 and a positioning ring 320. The rotating wheel 310 is installed in the installation groove 120. The rotating wheel 310 is fixedly mounted on the connecting portion 210. The inner side wall of the positioning ring 320 is provided with an internal thread, and the outer side wall of the connecting portion 210 is provided with an external thread. The positioning ring 320 is threadedly connected to the connecting portion 210. The positioning ring 320 is located on a side of the rotating wheel 310 away from the bottom wall of the installation groove 120. The positioning ring 320 can abut the rotating wheel 310 so that the rotating wheel 310 abuts the bottom wall of the installation groove 120.

[0033] During assembly, first pass the connecting portion 210 through the through hole 110 and extend into the mounting groove 120, then fix the rotating wheel 310 on the connecting portion 210. Since the inner side wall of the positioning ring 320 is provided with an internal thread and the outer side wall of the connecting portion 210 is provided with an external thread, the positioning ring 320 is then fitted on the connecting portion 210 and the positioning ring 320 is tightened. The positioning ring 320 abuts against the rotating wheel 310 so that the rotating wheel 310 abuts against the bottom wall of the mounting groove 120, and the handle 200 abuts against the mounting seat 100, thereby fixing the position of the rotating wheel 310 and the handle 200, so as to reduce the axial sliding of the rotating wheel 310 on the connecting portion 210 and make The handle 200 may become loose because the square groove 211 for clamping the square shaft is opened at the end of the connecting part 210, and the positioning ring 320 is mounted on the connecting part 210 and abuts the rotating wheel 310, so that the size of the positioning ring 320 is not limited by the size of the square groove 211, so that the positioning ring 320 can abut against the entire end face of the rotating wheel 310, and the contact area between the positioning ring 320 and the rotating wheel 310 can be increased to reduce the pressure between the positioning ring 320 and the rotating wheel 310 and increase the friction resistance, thereby reducing the possibility of the positioning ring 320 loosening due to vibration, and further improving the connection stability between the handle 200 and the rotating wheel 310.

[0034] When in use, the square shaft is clamped in the square groove 211, and the mounting base 100 is fixedly installed on the door and window. The connecting part 210 is connected to the lock core of the door and window through the square shaft. By rotating the handle 200, the connecting part 210 drives the rotating wheel 310 and the positioning ring 320 to rotate synchronously, and drives the square shaft to rotate, so as to drive the lock core of the door and window to lock or unlock, thereby opening or locking the door and window.

[0035] It should be noted that the wheel 310 is fixedly mounted on the connecting portion 210, which means that the wheel 310 can rotate synchronously with the connecting portion 210, and the wheel 310 can slide along the axial direction of the connecting portion 210. Since the wheel 310 and the positioning ring 320 can rotate synchronously with the connecting portion 210, the possibility of the positioning ring 320 loosening due to relative rotation between the wheel 310 and the positioning ring 320 can be reduced, thereby improving the connection stability between the handle 200 and the wheel 310.

[0036] A plurality of mounting holes 150 for passing bolts may be provided on the mounting base 100 so that the mounting base 100 can be fixedly mounted on doors and windows by means of bolts.

[0037] A first washer 600 can be set between the rotating wheel 310 and the bottom wall of the mounting groove 120, and the two sides of the first washer 600 respectively abut the bottom wall of the rotating wheel 310 and the mounting groove 120. The first washer 600 can reduce the rotational wear between the rotating wheel 310 and the bottom wall of the mounting groove 120. A second washer 700 can also be set between the handle 200 and the mounting seat 100, and the two sides of the second washer 700 respectively abut the handle 200 and the mounting seat 100. The second washer 700 can reduce the rotational wear between the handle 200 and the mounting seat 100.

[0038] It is understandable that, referring to Figure 2 、 Figure 5 and Figure 9 The cross section of the connecting portion 210 is arranged in a square shape, and a square hole 311 is provided at the center of the rotating wheel 310. The connecting portion 210 is inserted into the square hole 311. By inserting the connecting portion 210 into the square hole 311, the rotating wheel 310 is fixedly connected to the connecting portion 210, so that the rotating wheel 310 can rotate synchronously with the connecting portion 210. In addition, the assembly between the rotating wheel 310 and the connecting portion 210 can be completed by plugging, which can facilitate the disassembly and replacement of the rotating wheel 310.

[0039] Specifically, refer to Figure 2 、 Figure 5 、 Figure 6 and Figure 9 The four corners of the cross section of the connecting portion 210 are all set to arc shapes, so that the outer shape of the connecting portion 210 matches the inner shape of the positioning ring 320. The four corners of the cross section of the connecting portion 210 are all set to arc shapes, so that the outer shape of the connecting portion 210 matches the inner shape of the positioning ring 320, thereby facilitating the threaded connection between the positioning ring 320 and the connecting portion 210.

[0040] It should be noted that the positioning ring 320 is threadedly connected to the connecting portion 210 by matching the internal thread of the positioning ring 320 with the external thread on the arc-shaped side wall of the connecting portion 210 .

[0041] It is understandable that, referring to Figure 4 and Figure 6 The outer wall of the positioning ring 320 is provided with a plurality of tightening grooves 321, which are evenly spaced along the circumference of the positioning ring 320. The multiple tightening grooves 321 on the outer wall of the positioning ring 320 facilitate tightening the positioning ring 320 by inserting a corresponding tightening tool into the tightening grooves 321, thereby improving the tightness of the positioning ring 320 and reducing the possibility of the positioning ring 320 loosening. Furthermore, the evenly spaced circumference of the positioning ring 320 ensures balanced circumferential force on the positioning ring 320, reducing the possibility of deformation of the positioning ring 320 due to uneven force.

[0042] It should be noted that the tightening groove 321 extends axially to both end surfaces of the positioning ring 320 , so that a tightening tool can be inserted into the tightening groove 321 from one end of the positioning ring 320 to facilitate the rotation of the positioning ring 320 .

[0043] It is understandable that, referring to Figures 1 to 7 A groove 312 is formed on one side of the rotating wheel 310 near the positioning ring 320. The positioning ring 320 can be inserted into the groove 312 and abut against the bottom wall of the groove 312. Since the positioning ring 320 can be inserted into the groove 312 and abut against the bottom wall of the groove 312, when the positioning ring 320 is tightened, the rotating wheel 310 can protect the positioning ring 320, thereby reducing the possibility of the positioning ring 320 being loosened by accidentally touching the side wall of the positioning ring 320 during assembly, thereby improving the stability of the connection between the handle 200 and the rotating wheel 310.

[0044] Specifically, refer to Figures 1 to 7 Along the axial direction of the rotating wheel 310, the depth of the groove 312 is greater than or equal to the length of the positioning ring 320. Since the depth of the groove 312 along the axial direction of the rotating wheel 310 is greater than or equal to the length of the positioning ring 320, the end surface of the positioning ring 320 is lower than or flush with the end surface of the positioning ring 320, and the side wall of the positioning ring 320 is located within the groove 312. This can reduce the possibility of the positioning ring 320 being loosened by accidentally touching the side wall or end surface of the positioning ring 320 during assembly, thereby improving the stability of the connection between the handle 200 and the rotating wheel 310.

[0045] It is understandable that, referring to Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8The outer wall of the rotating wheel 310 is provided with a slot 313, and the side wall of the mounting groove 120 is provided with a receiving cavity 130. The mounting base 100 is provided with a clamping assembly 400, which includes a spring 410 and a steel ball 420. The spring 410 is installed in the receiving cavity 130, and the two ends of the spring 410 respectively abut the steel ball 420 and the wall surface of the receiving cavity 130. The spring 410 is used to drive the steel ball 420 to engage with the slot 313 to limit the rotation of the rotating wheel 310. By driving the steel ball 420 to engage with the slot 313 by the spring 410 to limit the rotation of the rotating wheel 310, the rotation angle of the handle 200 can be positioned, thereby reducing the possibility of the handle 200 rotating when the handle 200 is pushed to open or close the door or window, thereby improving the position stability of the handle 200.

[0046] It should be noted that when it is necessary to release the positioning of the handle 200, the handle 200 is rotated by applying force to make the steel ball 420 slide out of the slot 313 along the wall of the slot 313, and at the same time the spring 410 is compressed and deformed. The compressed spring 410 can drive the steel ball 420 to abut against the outer wall of the rotating wheel 310, causing the steel ball 420 to slide along the outer wall of the rotating wheel 310.

[0047] The shape of the slot 313 can match the outer shape of the steel ball 420 to increase the contact area between the steel ball 420 and the wall surface of the slot 313, thereby improving the positioning stability.

[0048] A bayonet 160 is formed at the connection between the mounting groove 120 and the accommodating cavity 130 . The diameter of the bayonet 160 is smaller than the diameter of the steel ball 420 , so that the steel ball 420 can partially extend into the mounting groove 120 and be stuck in the slot 313 , thereby preventing the steel ball 420 from falling into the mounting groove 120 .

[0049] Specifically, refer to Figure 7 and Figure 8 The accommodating cavity 130 is arranged along the radial direction of the mounting groove 120. Since the spring 410 is installed in the accommodating cavity 130, the accommodating cavity 130 guides the spring 410 to deform radially along the mounting groove 120, thereby driving the steel ball 420 to move radially along the mounting groove 120, which can improve the stability of the steel ball 420 being inserted into the engaging groove 313.

[0050] Specifically, refer to Figure 4 and Figure 5 The clamping assemblies 400 are provided in two groups, and the two groups of clamping assemblies 400 are arranged in opposite directions along the radial direction of the mounting groove 120. A plurality of clamping slots 313 are provided, and the plurality of clamping slots 313 are evenly spaced along the circumference of the rotating wheel 310. Because the two groups of clamping assemblies 400 are arranged in opposite directions along the radial direction of the mounting groove 120, the steel balls 420 on opposite sides are respectively engaged with the corresponding clamping slots 313. This allows the rotating angle of the rotating wheel 310 to be clamped and positioned from opposite radial sides of the rotating wheel 310, thereby improving positioning stability.

[0051] It should be noted that the number of the slots 313 can be an even number such as 2, 4 or 6, and the positioning angle of the handle 200 can be adjusted by adjusting the number of the slots 313 .

[0052] Specifically, refer to Figure 2 and Figure 8 The mounting base 100 has an opening 140 on the side close to the handle 200, and the opening 140 communicates with the accommodating cavity 130. The mounting base 100 has an outer cover 500 on the side close to the handle 200, and the outer cover 500 can block the opening 140. Since the mounting base 100 has an opening 140 on the side close to the handle 200, and the opening 140 communicates with the accommodating cavity 130, the spring 410 and the steel ball 420 can be easily installed in the accommodating cavity 130 through the opening 140, thereby facilitating the assembly of the spring 410 and the steel ball 420. The outer cover 500 is installed on the mounting base 100 to block the opening 140, which can prevent the spring 410 and the steel ball 420 from falling out of the accommodating cavity 130 through the opening 140, thereby improving the installation stability of the spring 410 and the steel ball 420.

[0053] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
