Description

Technical Field

[0001] This utility model relates to the field of architectural hardware, and in particular to a rotary window handle. Background Technology

[0002] A rotary window handle is a mechanical device that opens and closes a window by rotating it. It mainly consists of a rotary handle and a mounting base. The mounting base is fixed to the edge of the window, and the rotary handle is rotatably mounted on the mounting base. When the window is closed, turning the rotary handle causes the lock cylinder on the handle to screw into a lock groove in the window frame or wall, thus locking the window. However, existing rotary window handles rotate parallel to the window. The window needs to be closed until it is parallel to the lock groove for the lock cylinder to rotate and align. When the window is closed, it may slightly deflect outwards if not pulled firmly, causing the window and lock groove to become misaligned. This means that when locking the window, one needs to pull the handle firmly inwards to keep the window closed before rotating the handle and locking the lock cylinder. This makes the window-closing experience very poor. Utility Model Content

[0003] To overcome the above problems, this utility model provides a rotary window handle. The technical solution adopted by this utility model to solve its technical problems is as follows:

[0004] A rotary window handle includes a mounting base and a rotary handle. The mounting base is fixedly mounted on the window, and the rotary handle is equipped with a lock head. The rotary handle is mounted on the mounting base via a rotating assembly. The mounting base has an arc-shaped surface, and the rotating assembly has an arc-shaped protrusion that abuts against the arc-shaped surface. The rotary handle drives the rotating assembly to rotate relative to the mounting base, and the arc-shaped protrusion rotates and undulates along the arc-shaped surface, causing the lock head to rotate while vertically approaching / vertically moving away from the window lock groove.

[0005] Furthermore, a ball is provided on the arc-shaped protrusion, and the arc-shaped protrusion abuts against the arc-shaped surface through the ball, and the arc-shaped protrusion rolls along the arc-shaped surface through the ball.

[0006] Furthermore, the rotating assembly includes a front cover and a rear cover. The rear end face of the front cover and the front end face of the rear cover are both provided with arc-shaped protrusions, and each arc-shaped protrusion is provided with a ball. A rotating ring is provided on the mounting base. The front end face and the rear end face of the rotating ring are both provided with arc-shaped curved surfaces. The front cover and the rear cover are connected through the inner hole of the rotating ring. The rear end face of the front cover abuts against the front end face of the rotating ring, and the front end face of the rear cover abuts against the rear end face of the rotating ring to hold the rotating ring tightly. The rotating handle and the rotating assembly are fixedly connected.

[0007] Furthermore, a connecting arm is provided on the rotary handle, which passes through the front cover and the rear cover and is fixed to the rotary assembly by screws.

[0008] Furthermore, the connecting arm is provided with a limiting protrusion, and both the front cover and the rear cover are provided with matching grooves. The limiting protrusions are inserted into the matching grooves of the front cover and the rear cover in sequence to drive the rotating component to rotate relative to the mounting base.

[0009] Furthermore, a friction head is detachably and fixedly mounted on the lock head.

[0010] The beneficial effects of this utility model are as follows:

[0011] This window handle includes a mounting base and a rotating handle. The mounting base is fixedly installed on the window, and the rotating handle has a lock head. The rotating handle is mounted on the mounting base via a rotating assembly. The mounting base has an arc-shaped surface, and the rotating assembly has an arc-shaped protrusion that abuts against the arc-shaped surface. The rotating handle drives the rotating assembly to rotate relative to the mounting base, and the arc-shaped protrusion rotates and undulates along the arc-shaped surface, causing the lock head to rotate while simultaneously moving vertically towards / away from the window. Thus, when locking the window, after closing the window, it is not necessary to forcefully pull the handle inward to ensure the window is closed parallel to the lock groove. Simply turning the rotating handle causes the lock head to make a parabolic motion vertically towards the window lock groove, automatically locking the lock head inward into the lock groove, easily completing the window closing operation and providing a good user experience.

[0019] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of the "rotary window handle" of this utility model is provided in conjunction with the accompanying drawings.

[0020] See Figures 1-4 In this embodiment, the rotating window handle includes a mounting base 100 and a rotating handle 101. The mounting base 100 is fixedly mounted on the edge of the window by screws, and the rotating handle 101 is provided with a lock head 102. The rotating handle 101 is mounted on the mounting base 100 by a rotating assembly. The mounting base 100 is provided with an arc-shaped curved surface 103 that has undulations relative to the window plane, and the rotating assembly is provided with an arc-shaped protrusion 104. The arc-shaped protrusion 104 abuts against the arc-shaped curved surface 103 and can move along the arc-shaped curved surface 103. When you need to close the window, first close the window so that the rotary window handle is close to the lock groove on the frame / wall. Then turn the rotary handle 101 to lock the window. The rotary handle 101 drives the rotating component to rotate relative to the mounting base 100. The arc-shaped protrusion 104 rotates and undulates along the arc-shaped surface 103, driving the lock head 102 to rotate while vertically approaching the lock groove of the window. The lock head 102 makes an inward parabolic motion and naturally enters the lock groove. It is not necessary to maintain a force to pull the window tight at all times when turning the rotary handle 101 to lock the window, which can improve the user experience of locking / unlocking the window by turning the rotary handle 101.

[0021] See further Figure 2 and Figure 3 In this embodiment, a ball bearing 105 is provided on the arc-shaped protrusion 104. The arc-shaped protrusion 104 abuts against the arc-shaped curved surface 103 through the ball bearing 105, and the arc-shaped protrusion 104 rolls along the arc-shaped curved surface 103 through the ball bearing 105. The ball bearing 105 changes the sliding friction into rolling friction, making the rotating handle 101 rotate more smoothly and stably when rotating the window lock.

[0022] See further Figures 2-4In this embodiment, the rotating assembly includes a front cover 106 and a rear cover 107. The rear end face of the front cover 106 and the front end face of the rear cover 107 are both provided with arc-shaped protrusions 104, and each arc-shaped protrusion 104 is provided with a ball 105. A rotating ring 108 is provided on the mounting base 100. The front end face and the rear end face of the rotating ring 108 are both provided with arc-shaped curved surfaces 103. The front cover 106 and the rear cover 107 are connected through the inner hole of the rotating ring 108. The rear end face of the front cover 106 abuts against the front end face of the rotating ring 108, and the front end face of the rear cover 107 abuts against the rear end face of the rotating ring 108 to hold the rotating ring 108 tightly. The rotating handle 101 and the rotating assembly are fixedly connected. In this way, when the rotating handle 101 drives the rotating assembly to rotate relative to the mounting base 100, the design of the front cover 106 and the rear cover 107 clamping the rotating ring 108 can make the rotation and back-and-forth movement of the lock head 102 smoother and more stable. It should be noted that the curved surfaces 103 of the front and rear faces of the rotating ring 108 are designed with a staggered shape, with the valley of one side corresponding to the peak of the other side, ensuring that when the lock head 102 rotates to close, it rotates inward (closer to the window) into the valley, and when the lock head 102 rotates to open, it rotates outward (away from the window) to the peak.

[0023] More specifically, in this embodiment, a connecting arm 109 is provided on the rotating handle 101. The connecting arm 109 passes through the front cover 106 and the rear cover 107 and is fixed to the rotating assembly by screws 110. The connecting arm 109 is provided with a limiting protrusion 111, and both the front cover 106 and the rear cover 107 are provided with matching grooves 112. The limiting protrusion 111 passes through the matching grooves 112 of the front cover 106 and the rear cover 107 in sequence to stably drive the rotating assembly to rotate relative to the mounting base 100.

[0024] See further Figure 1 In this embodiment, a friction head 113 is detachably fixed at the front end of the lock head 102 so that it can be replaced after wear. The friction head 113 can be made of wear-resistant rubber, wear-resistant alloy or other materials.
