Elements of technical realization of multi-angle limit door and window handles

Technical implementation elements:

3. The technical problem to be solved by the present utility model is to overcome the deficiencies of the prior art, and to provide a multi-angle limit door and window handle that is easy to install, rotates smoothly, feels good, and can support multi-angle limit.

4. The technical scheme adopted by the present invention is: the present invention comprises a base that is rotatably connected with the handle and the base is provided with a base that is fixedly connected to the handle and rotatably matched with the base. A rotating seat and a limiting bottom plate arranged at the bottom of the base to limit the rotating seat, a limiting mechanism is provided on the rotating seat, a lock cylinder hole is provided on the axis of the rotating seat, and the limiting mechanism includes Several horizontal limit holes are arranged around the lock cylinder hole array, and transverse springs and transverse limit steel balls are arranged in the horizontal limit holes. One end of the transverse spring is connected with the transverse limit steel ball, and the other end is connected with the transverse limit steel ball. The bottoms of the horizontal limit holes are connected, and a plurality of positioning grooves that are matched with the transverse limit steel balls one by one are arranged on the inner side wall of the base around the axis array. Under normal conditions, the utility model applies a horizontal force to the lateral limit steel ball through the lateral spring, so that the lateral limit steel ball always sticks to the inner wall of the base during the rotation of the rotating seat, thereby To ensure the smooth rotation of the utility model, when the handle drives the rotating base to rotate by a certain angle, the lateral limit steel balls enter into the corresponding positioning grooves to realize the limit function.

5. Preferably, the rotating seat is provided with four horizontal limiting holes, and correspondingly, the number of the springs, the limiting steel balls and the positioning grooves is also four. Therefore, the utility model can be used in 360°Spin at 90°

It is the first gear, which is divided into four gears in total, which realizes the multi-angle limit function under the condition that the rotation angle of the lock cylinder is satisfied.

6. Preferably, the limiting mechanism further comprises several vertical limiting holes arranged around the lock cylinder hole array, and vertical springs and vertical limiting steel balls arranged in the vertical limiting holes, so One end of the vertical spring is connected with the vertical limit steel ball, and the other end is connected with the bottom of the vertical limit hole. A number of vertical limit steel balls are arranged one by one on the limit base plate around the axis. A number of guide holes with diameters smaller than the positioning holes are also arranged between adjacent positioning holes. Through the cooperation between the vertical spring, the vertical limit steel ball and the positioning hole, a plurality of vertical forces are applied to the rotating seat, which further enhances the rotating feel of the present invention, and it is clear that Limit gear; the guide holes arranged between the adjacent positioning holes can effectively eliminate the virtual position between different limit positions and eliminate the shaking during use.

7. Preferably, four vertical limiting holes are provided on the rotating seat, and correspondingly, the number of the vertical springs, the vertical limiting steel balls and the positioning holes is also four. Piece. Therefore, the horizontal direction force and the vertical direction force applied on the rotating seat are consistent, which further ensures the use effect of the present invention.

8. Preferably, two guide holes are provided between adjacent positioning holes.

9. Preferably, the upper end of the rotating seat is provided with a fixed column, the upper end of the outer side wall of the fixed column is provided with four cut surfaces around the axis array, the fixed column is provided with a square hole at the axis position, and the handle is provided with The mounting hole is adapted to the fixing post, and the axial position of the mounting hole is provided with a connecting post adapted to the square hole. The rotating seat is connected with the handle through the cut surface and the square hole, so as to ensure the rotational connection between the two, so that the rotating seat can smoothly rotate with the handle.

10. Preferably, the base includes a base body and a base cover, the base body is provided with a circular concave hole that matches the lower end of the rotating base, and the upper surface of the base body is also provided with the fixing column. A matching circular boss, the circular concave hole is communicated with the circular boss, and the positioning groove provided on the inner side wall of the circular concave hole is a circular arc groove. The inner cavity formed by the circular concave hole and the circular boss is adapted to the rotating seat, which effectively reduces the shaking of the rotating seat during rotation.

11. Preferably, a circular opening adapted to the circular boss is provided on the seat cover.
