[0038] Referring to Figure 6The square shaft 15 has an input shaft section, an output shaft section and an intermediate connecting section. The input shaft section is connected to the square cavity shaft, the connecting section is fixedly connected to the central hole wall of the base 6, and the output shaft section extends out of the base 6.

[0039] In one embodiment provided in this application, see Figure 3 The handle 17 has a set screw hole 21 on its side, see [reference]. Figure 5 The input shaft section of the square shaft 15 is provided with a second set screw hole 26, through which the set screw 8 is passed and fixed to the second set screw hole 26.

[0040] In one embodiment provided in this application, the positioning bead 12 connected to the end of the spring 9 is accommodated in the positioning countersunk hole 10 and / or located in the track 13.

[0041] In one embodiment provided in this application, see Figure 4 The positioning countersunk holes 10 are six in number, including four first positioning countersunk holes evenly distributed around the axis and two second positioning countersunk holes. The two second positioning countersunk holes are symmetrically arranged between two pairs of adjacent first positioning countersunk holes. The first positioning countersunk holes and the axis line, and the second positioning countersunk holes and the axis line form an angle of 45 degrees or 135 degrees.

[0042] In one embodiment provided in this application, the spring 9 and the positioning beads 12 are each provided in groups of four and are evenly distributed along the axis of the annular cavity; in the natural state, the four positioning beads 12 are engaged in the four first positioning countersunk holes.

[0043] In one embodiment provided in this application, the bottom of the handle 17 is provided with an annular cavity and a square cavity in sequence. The handle 17 is L-shaped, with its root for fixing to the profile 1 and its tail for the user to apply torque. The root of the handle 17 has an annular cavity, and the bottom center of the annular cavity has a square cavity with an inner diameter smaller than the annular cavity for accommodating the input shaft section of the square shaft 15. The bottom surface of the annular cavity has a spring hole for accommodating the spring 9, and the spring hole is coaxially arranged with four first positioning countersunk holes. One end of the spring 9 is fixed in the spring hole, and the other end is fixed to the positioning bead 12. In this method, the portion of the spring 9 located in the spring hole is radially limited, which also facilitates the positioning and installation of the spring 9.

[0044] In one embodiment provided in this application, see Figure 7 , 8 Profile 1 has pre-drilled profile screw holes 4 and profile through holes 5. The output shaft section of the square shaft 15 passes through the base 6 and is fixed through the profile through hole 5. The positioning ring 22 passes through the profile screw hole 4 and is confined within the profile screw hole 4. A screw 7 passes through the inner hole of the positioning ring 22 and is fixed to the profile 1.

[0045] In one embodiment provided by the present application, referring to Figure 9 , the bottom of the handle 17 houses the base 6 so as to hide it in the handle 17, and a gasket 16 is arranged between the bottom of the handle 17 and the profile 1.

[0046] In one embodiment provided by the present application, the inner diameter of the positioning ring 22 is equal to the hole diameter of the counterbore limiting screw hole 14, and the positioning ring protrudes from the second end of the base 6 and the height does not exceed the thickness of the panel 2 for fixing the lever handle 3 on the profile 1.

[0047] In one embodiment provided by the present application, referring to Figure 6 , a limiting clamping groove is arranged in the middle connecting section of the square shaft 15, and a clamping spring 24 is arranged in the clamping groove 25 to limit the axial movement of the square shaft 15.

[0048] In one embodiment provided by the present application, referring to Figure 2 , a gasket one 19 is arranged between the recess and the first end of the positioning plate 18; referring to Figure 6 , a gasket two 20 is arranged between the shaft shoulder between the connecting shaft section and the output shaft section of the square shaft 15 and the base 6.

[0049] The positioning mechanism of the present application comprises a positioning plate 18 mounted on the base of the lever handle, a positioning counterbore 10 arranged on the positioning plate 18, a spring 9 and a positioning bead 12 arranged at the bottom end of the spring 9, wherein the positioning bead 12 presses the side of the positioning plate 18 with the positioning counterbore 10. Six positioning counterbores 10 are designed in the positioning mechanism, and with such a structure, the positioning bead 12 can abut against the positioning counterbores 10 or the track 13 of the positioning plate 18 when the lever handle 17 rotates, and the positioning bead 12 will be in the positioning counterbores 10 every 45 degrees, thereby realizing the multi-angle positioning function during rotation.

[0050] The base 6 structure of the present application is provided with a square shaft 15 embedded in the base 6, which comprises a positioning column hole 23 for connecting with the positioning mechanism, a limiting screw hole 14 for passing through the screw 7 when fixed with the profile 1, and a limiting structure-positioning ring 22 for limiting the profile 1. In the base 6 structure, the positioning ring 22 protrudes from the plane of the base 6, and during the installation with the profile 1, the protruding part of the positioning ring 22 is clamped in the profile screw hole 4, realizing the positioning function, and then the screw 7 is fixed by passing through the counterbore limiting screw hole 14 and the positioning ring 22. With such a structure, the profile only needs to mill two profile screw holes 4, making the installation more simple and convenient.

[0051] The proposed gasket structure is added to the bottom of the profile 1 and the handle 17 after the handle 3 is installed with the profile 1. This makes the gap between the profile 1 and the base 6 and the bottom of the handle invisible, making the overall appearance simpler and more beautiful. It also protects the profile and handle and prevents wear.

[0052] The technical solution of this application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0053] See Figure 7 and Figure 8 As shown, profile screw holes 4 and profile through holes 5 are pre-drilled on the door or window profile 1; the square shaft 15, which is fixed to the handle base 6, passes through the profile through hole 5, and the screw 7 passes through the limit screw hole 14 to fix the handle base 6 to the profile 1. The bottom of the handle handle 17 accommodates the handle base 6, thereby hiding it inside the handle handle 17. The handle handle part and the base part are fixed by tightening the set screw 8.

[0054] See Figures 2 to 4 As shown, the rotation positioning mechanism includes a positioning plate 18, a spring 9, and positioning beads 12. The positioning plate 18 has a track 13 for the positioning beads 8 to roll and positioning countersunk holes 10 for positioning. The positioning plate 18 has 6 positioning countersunk holes 10. During the rotation of the handle 3, at least 2 positioning beads 8 will fall into the positioning countersunk holes 10 every 45 degrees. The spring 9 presses down on the positioning beads 8, so that the torque needs to be increased during the rotation to make the positioning beads roll out of the positioning countersunk holes 10, thus realizing the positioning function of the handle 3.

[0055] See Figure 5 and Figure 6 As shown, in the base structure, the limiting screw hole 14 and the positioning ring 22 combine the functions of screw through holes and limiting. During the installation of the base 6 and the profile 1, the frame profile 1 only needs to have two profile screw holes 4 and one profile through hole 5 pre-drilled. The difference between the limiting screw hole 14 and the traditional screw hole is that the limiting screw hole 14 integrates the positioning ring 22, allowing the positioning ring 22 to be locked in the pre-drilled profile screw hole 4 of the profile 1. Then, the base 6, together with the rotating mechanism, is fixed to the profile 1 using screws 7, thus achieving both limiting and fixing functions. This structure makes fixing the opening of the profile 1 and the base 6 much simpler.

[0056] See Figure 9 As shown, a washer 16 is added between the bottom of the handle 3 and the frame profile 1. During the rotation of the handle 3, the washer 16 can protect the bottom of the handle 3 from wear. In terms of overall appearance, the gap between the frame profile 1 and the base 6 becomes invisible, making its overall appearance more concise and beautiful.

[0057] It should be noted that the present application only protects and limits the handle part, and does not involve the improvement of the lock head and the lock tongue part. The user can rotate the handle to drive the internal square shaft to rotate, and the output end of the square shaft is used to drive the opening and closing of the lock tongue part. However, how to drive the movement of the lock tongue part is not solved by the present application, but is a content that can be achieved by the prior art. It can be understood that the angle of rotation of the handle is positively correlated with the length of the lock tongue.

[0058] The above-described embodiments are only the preferred embodiments of the present application, and do not limit the present application in any form. Any skilled person in the art can make more possible changes and decorations to the technical solutions of the present application, or modify equivalent embodiments with equivalent changes, without departing from the scope of the technical solutions of the present application, using the disclosed technical content. Therefore, any equivalent equivalent changes made in accordance with the ideas of the present application, without departing from the content of the technical solutions of the present application, shall be covered within the protection scope of the present application.
