For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0033] like Figures 1 to 7 As shown, a multi-angle rotating door and window handle 10 is provided in one embodiment of the present invention. The above-mentioned door and window handle 10 includes a handle 10, a handle base 20, a transmission member 30 and a square steel 40; the handle 10 is arranged on the handle base 20, the transmission member 30 passes through the handle base 20 and is connected to the handle 10, and the square steel 40 is connected to the end of the transmission member 30 away from the handle 10; when in use, rotating the handle 10 can drive the transmission member 30 and the square steel 40 to rotate, and the square steel 40 is connected to the door and window structure to realize the opening, closing, locking, unlocking and other functions of the doors and windows.

[0034] The handle 10 and the handle base 20 are provided with a limit assembly, one end of the limit assembly is connected to the handle base 20, and the other end of the limit assembly is connected to the handle 10; the handle base 20 is provided with a first limit groove 203 on the side facing the handle 10, and the limit assembly has a first position and a second position relative to the first limit groove 203; when the limit assembly is in the first position, as shown in FIG. Figure 6 and Figure 7As shown, the limiting assembly is inserted into the first limiting groove 203, and the handle 10 can rotate around the arc of the first limiting groove 203. When the limiting assembly is in the second position, as shown in FIG. Figure 4 and Figure 5 As shown, the limiting assembly is disengaged from the first limiting groove 203, and the handle 10 can rotate 360°.

[0035] By adopting this technical solution, the same door and window handle 10 can be rotated at two angles. Users can adjust and select according to their own needs, meeting the needs of different angles. At the same time, it can reduce the time cost and other expenses of changing the model of the door and window handle 10 due to needs.

[0036] Specifically, a handle seat pad 201 is provided within the inner cavity of the handle base 20. The transmission member 30 passes through the handle seat pad 201 and the handle base 20 in sequence, and is then connected to the handle 10 via screws 110, thereby achieving a connection between the transmission member 30 and the handle 10. Furthermore, a hole for a square steel 40 is provided at the end of the transmission member 30 facing away from the handle 10. One end of the square steel 40 is inserted into the hole in the square steel 40, thereby achieving an assembled connection between the square steel 40 and the transmission member 30. Because the connection structure between the handle 10, the handle base 20, the transmission member 30, the square steel 40, and the screw 110 is conventional, it will not be further described here. In this embodiment, the first limiting groove 203 is an arcuate groove with a central angle of 90°; understandably, in other embodiments, arcuate grooves with other angles may also be used.

[0037] In some embodiments, as Figure 2 As shown, the limiting assembly includes an adjusting washer 50, a magnetic member 60, a connecting seat 70 and a limiting pin 80. The adjusting washer 50 is sleeved on the connecting seat 70. The connecting seat 70 is provided on the side of the handle seat 20 facing the handle 10. The magnetic member 60 is provided on the adjusting washer 50. The limiting pin 80 is movably connected to the connecting seat 70. The transmission member 30 passes through the handle seat 20 and the connecting seat 70 in sequence and is connected to the handle 10.

[0038] When in use, when the limit assembly is in the first position, Figure 6 and Figure 7 As shown, the magnetic member 60 is separated from the limiting pin 80, one end of the limiting pin 80 is located in the connecting seat, and the other end of the limiting pin 80 is inserted into the first limiting groove 203. At this time, the handle 10 can rotate around the arc of the first limiting groove 203. When the limiting assembly is in the second position, as shown in FIG. Figure 4 and Figure 5 As shown, the magnetic member 60 and the limiting pin 80 fit together under the action of magnetic force, and the limiting pin 80 is located in the connecting seat 70. At this time, the limiting pin 80 has no interference with the first limiting groove 203, and the handle 10 can rotate 360°.

[0039] Specifically, the adjusting washer 50 is provided with a first through hole 501 and a socket 502 arranged along the axial direction, and the magnetic member 60 is arranged in the socket 502; the connecting seat 70 includes a first cylindrical portion 701 and a second cylindrical portion 702 arranged coaxially, the radius of the first cylindrical portion 701 is smaller than the radius of the second cylindrical portion 702, and the second cylindrical portion 702 is provided with a pin hole 7021 arranged along the axial direction, and the limiting pin 80 is arranged in the pin hole 7021; the handle seat 20 is provided with a boss 202 on the side facing the handle 10, the second cylindrical portion 702 is sleeved on the boss 202, and the first cylindrical portion 701 is inserted into the through hole. When the limiting component is in the first position, as shown in FIG. Figure 6 and Figure 7 As shown, the insertion hole 502 does not overlap with the pin hole 7021; when the limit assembly is in the second position, as shown Figure 4 and Figure 5 As shown, the insertion hole 502 coincides with the pin hole 7021 .

[0040] When the door and window handle 10 needs to be adjusted in rotation angle, an external force is applied to the adjusting washer 50 to rotate the adjusting washer 50. When the position of the insertion hole 502 on the adjusting washer 50 does not coincide with the position of the pin hole 7021, the magnetic force of the magnetic member 60 cannot act on the limit pin 80. Figure 6 and Figure 7 As shown, the magnetic part 60 and the limit pin 80 are separated from each other, one end of the limit pin 80 is located in the pin hole 7021, and the other end is inserted into the first limit groove 203; since the first cylindrical portion 701 is connected to the handle 10, when the handle 10 is rotated, the handle 10 will drive the connecting seat 70 to rotate synchronously; after rotating to a certain angle, the limit pin 80 will abut against the inner wall of the first limit groove 203, and under the interference, the handle 10 cannot continue to rotate.

[0041] When the position of the insertion hole 502 on the adjustment washer 50 coincides with the position of the pin hole 7021, the magnetic force of the magnetic member 60 attracts the limit pin 80, causing the limit pin 80 to move along the pin hole 7021 toward one side of the handle 10, as shown in FIG. Figure 4 and Figure 5 As shown, the magnetic member 60 fits with the limiting pin 80 , and the limiting pin 80 is completely located in the pin hole 7021 , that is, the limiting pin 80 has no interference with the first limiting groove 203 , so the handle 10 can rotate 360°.

[0042] In some embodiments, the outer wall of the adjusting washer 50 is provided with a first ridge 503, and the outer wall of the second cylindrical portion 702 is provided with a second ridge 7022. Furthermore, the first ridge 503 is provided corresponding to the insertion hole 502, and the second ridge 7022 is provided corresponding to the pin hole 7021. When the stop assembly is in the first position, the position of the first ridge 503 and the position of the second ridge 7022 do not overlap, that is, the insertion hole 502 and the pin hole 7021 do not overlap. When the stop assembly is in the second position, the position of the first ridge 503 and the position of the second ridge 7022 overlap, that is, the insertion hole 502 and the pin hole 7021 overlap.

[0043] The first ridge 503 and the second ridge 7022 are provided to facilitate the relative position of the insertion hole 502 and the pin hole 7021 when the adjustment washer 50 is rotated, thereby determining the relative position of the limit pin 80 and the magnetic member 60. This facilitates the user to understand whether the magnetic member 60 and the limit pin 80 overlap.

[0044] In some embodiments, the pin hole 7021 includes a first hole and a second hole that are coaxially arranged and connected, the first hole is arranged toward the socket 502, and the second hole is arranged toward the handle base 20; the diameter of the first hole is larger than the diameter of the second hole; the limiting pin 80 is a T-type screw 110, and the T-type screw 110 includes a nut, the nut is clearance-fitted with the first hole, and the diameter of the nut is larger than the diameter of the second hole.

[0045] Since the aperture of the first hole is larger than that of the second hole, and the nut on the T-screw 110 is loosely fitted with the first hole, the diameter of the nut is larger than the diameter of the second hole, and the screw rod on the T-screw 110 is loosely fitted with the second hole, when the T-screw 110 moves axially in the pin hole 7021, the connection between the first hole and the second hole will limit the nut on the T-screw 110 from continuing to move, thereby preventing the limit pin 80 from falling off from the pin hole 7021.

[0046] In some embodiments, the magnetic member 60 in the present application is interference fit with the socket 502 , so that the magnetic member 60 is stably fixed in the socket 502 to prevent it from falling off from the socket 502 .

[0047] In some embodiments, as Figure 3 As shown, the inner diameter of the first through hole 501 in the present application is larger than the outer diameter of the first cylindrical portion 701. Since the inner diameter of the first through hole 501 is larger than the outer diameter of the first cylindrical portion 701, when the adjusting washer 50 is mounted on the outside of the first cylindrical portion 701, a gap is left between the adjusting washer 50 and the first cylindrical portion 701, thereby facilitating the rotation of the adjusting washer 50.

[0048] In some embodiments, as Figure 2 and Figure 3As shown, the multi-angle rotating door and window handle 10 of the present invention also includes a handle base cover 90. The handle base cover 90 is snap-fitted to the side of the handle base 20 facing the handle 10. The handle base cover 90 is provided with a second limiting groove 902, which is arranged corresponding to the first limiting groove 203. When the limiting assembly is in the first position, one end of the limiting pin 80 is located in the connecting base 70, and the other end of the limiting pin 80 passes through the second limiting groove 902 and is inserted into the first limiting groove 203. The handle base cover 90 acts as a seal to prevent dust and other debris from falling into the handle base 20. In addition, the handle base cover 90 is also provided with a second through hole 901, into which the boss 202 of the handle base 20 is inserted.

[0049] In some embodiments, as Figure 2 As shown, the multi-angle rotating door and window handle 10 of the present invention further includes an elastic ring 100, which is sleeved on the boss 202 and arranged between the handle base cover 90 and the connecting base 70. The main function of the elastic ring 100 is to press the handle base cover 90 to prevent the handle base cover 90 from shaking.

[0050] The present invention also provides a door and window, comprising a door and window body and a multi-angle rotating door and window handle 10 as described in any one of the embodiments of the present application, wherein the multi-angle rotating door and window handle 10 is arranged on the door and window body.

[0051] Compared with the prior art, the multi-angle rotating door and window handle and door and window involved in the utility model include a handle 10, a handle base 20, a transmission part 30, a square steel 40 and a limit assembly; rotating the handle 10 can drive the transmission part 30 to drive the square steel 40 to rotate, thereby realizing the opening and closing of the door and window; wherein the handle base 20 is provided with a first limit groove 203, and the limit assembly is arranged between the handle 10 and the handle base 20; when the limit assembly is inserted into the first limit groove 203, the handle 10 can rotate around the arc of the first limit groove 203; conversely, when the limit assembly is disengaged from the first limit groove 203, the handle 10 can rotate 360°; therefore, the handle 10 can rotate to a certain angle or 360°, while meeting the requirements of two rotation angles; in addition, switching between the two rotation angles is flexible and convenient.

[0052] The above merely represents the preferred technical solution of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
