Description

Technical Field

[0001] This utility model relates to the technical field of door and window hardware accessories, specifically to a door and window handle mechanism. Background Technology

[0002] The door and window handle mechanism is the core component for opening and closing doors and windows, used to drive the locking mechanism and achieve locking and unlocking. Existing door and window handle mechanisms typically include a mounting base, a rotating sleeve, a limiting plate, a positioning component, and a handle. The mounting base is fixed to the door or window and has spring holes along its circumference. The rotating sleeve passes through the mounting base, and the limiting plate is fitted onto the rotating sleeve. The limiting plate has limiting holes, and the positioning component, located within the spring holes, cooperates with the limiting holes to provide feedback and maintain the rotation angle. The handle is located on the outside of the rotating sleeve and connected to it via a connector. However, in traditional structures, the limiting plate and rotating sleeve are often connected by bolts, and their axial position is controlled by the bolts. If the bolts are too loose, the stop may be unclear or the handle may wobble, affecting the user experience; if the bolts are too tight, the handle will have high rotational resistance, making operation difficult. Furthermore, bolted connections have low installation efficiency, and axial positioning accuracy is difficult to guarantee. Utility Model Content

[0003] The purpose of this utility model is to provide a door and window handle mechanism to solve the problems of inconvenient installation, poor positioning accuracy, easy swinging of the handle or high rotation resistance in the existing technology of the connection between the limiting plate and the rotating sleeve.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A door and window handle mechanism includes: a mounting base for fixing to a door or window, the mounting base having a plurality of spring holes along its circumference; a rotating sleeve rotatably inserted into the mounting base, the outer wall of the rotating sleeve having a plurality of rivet posts; a limiting plate having a mounting hole, the wall of the mounting hole having a rivet groove corresponding to the rivet posts, the limiting plate being sleeved on the rotating sleeve through the mounting hole and circumferentially limiting it, the rivet posts cooperating with the rivet grooves and riveting the rivet posts to the limiting plate, the limiting plate having a limiting hole along its circumference adapted to the spring holes; a positioning component, at least partially placed in the spring holes, elastically cooperating with the limiting holes to achieve positioning of the rotation angle of the rotating sleeve; and a handle sleeved on the outside of the rotating sleeve and circumferentially limiting it, the handle being connected to the rotating sleeve through a connector.

[0005] In the above technical solution, the limiting plate and the rotating sleeve are fixed by riveting. Compared with the traditional bolt connection, the installation method is faster and more convenient, the axial position is more accurate, and there will be no problems such as unclear stop or handle swing due to loose connection, or large resistance to handle rotation due to tight connection. At the same time, the structure is more compact and reliable.

[0006] Preferably, the positioning component includes a first spring and a limiting steel ball, wherein the first spring pushes the limiting steel ball to fit into the limiting hole of the limiting plate. The positioning component adopts an elastic cooperation structure of spring and steel ball, which is simple in structure, provides clear feedback on rotation angle, has a clear sense of stop, and is stable and reliable in long-term use.

[0007] Preferably, a circular sleeve is provided at one end of the rotating sleeve, and the rotating sleeve is rotatably connected to the mounting base through the circular sleeve. The riveting post is disposed on the side of the rotating sleeve near the circular sleeve, and the riveting post and the circular sleeve together provide axial positioning of the limiting plate. By using the riveting post and the circular sleeve to axially position both ends of the limiting plate, the axial position of the limiting plate is fixed and reliable, and no axial movement will occur during rotation, further ensuring the gear positioning accuracy and operating feel.

[0008] Preferably, the device also includes a toggle element, which works in conjunction with the rotating sleeve to lock or unlock the doors and windows.

[0009] Preferably, the actuating element is a square rod, which is disposed within the rotating sleeve. A second spring is provided between the end of the square rod and the end of the handle connector to control the axial position of the square rod within the rotating sleeve. By controlling the axial position of the square rod through the elastic force of the second spring, the square rod can adaptively adjust its extension length to meet the installation requirements of door and window profiles of different thicknesses, thereby improving the versatility and ease of installation of the mechanism.

[0010] Preferably, the actuating element is a shift fork, which is slidably mounted on the mounting base. The shift fork is equipped with a rack, and the rotating sleeve is equipped with meshing teeth that mesh with the rack. Through the meshing of the meshing teeth on the rotating sleeve and the rack on the shift fork, the rotational motion is converted into linear sliding of the shift fork, resulting in smooth and reliable transmission and enabling linear drive of the door and window locking points.

[0013] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0014] Example 1: As Figures 1 to 5 The door and window handle mechanism shown includes a mounting base 1, a rotating sleeve 2, a limiting plate 3, a positioning component 4, a handle 5, and a toggle component 7.

[0015] Mounting base 1 is used to fix it to door and window profiles. A housing 12 is fitted over the outside of mounting base 1 to improve overall aesthetics and protection. Several spring holes 11 are evenly distributed around the circumference of mounting base 1. In this embodiment, there are six spring holes 11, all of which are through slot structures, providing six rotation angle feedback positions. A pad 9 is provided on one end face of mounting base 1 corresponding to the spring holes 11.

[0016] The rotating sleeve 2 is rotatably mounted at the geometric center of the mounting base 1. The rotating sleeve 2 has a rotating sleeve 2, one end of which is provided with a turntable 22. A circular sleeve 21 is provided between the rotating sleeve 2 and the turntable 22. The rotating sleeve 2 is rotatably connected to the mounting base 1 through the circular sleeve 21. The turntable 22 is located on the side of the mounting base 1 away from the handle 5. The outer wall of the rotating sleeve 2 is provided with several riveting posts 8, which are located on the side of the rotating sleeve 2 closest to the circular sleeve 21.

[0017] A mounting hole 32 is provided at the geometric center of the limiting plate 3. The limiting plate 3 is fitted onto the rotating sleeve 2 through the mounting hole 32 and is circumferentially limited by the rotating sleeve 2. The circumferential limitation can be achieved by known methods such as non-circular cross-section fit, key connection, or convex strip structure. A riveting groove 33 is provided on the wall of the mounting hole 32 corresponding to the riveting post 8. The limiting plate 3 is fitted onto the rotating sleeve 2 through the mounting hole 32 and is circumferentially limited by it. The riveting post 8 fits into the riveting groove 33. The upper part of the riveting post 8 is punched through the die punching hole and abuts against the end face of the limiting plate 3 to realize the riveting fixation and axial limitation of the limiting plate 3 and the rotating sleeve 2. The riveting post 8 and the round sleeve 21 together axially limit the limiting plate 3, so that the axial position of the limiting plate 3 is accurately fixed. Limiting holes 31 that are adapted to the spring hole 11 are provided on the circumference of the limiting plate 3. The number of limiting holes 31 corresponds to the number of spring holes 11, and there are six of them.

[0018] The positioning component 4 is at least partially placed within the spring hole 11. In this embodiment, the positioning component 4 includes a first spring 41 and a limiting steel ball 42. The first spring 41 is disposed within the spring hole 11, with one end abutting against the pad 9 and the other end abutting against the limiting steel ball 42. The first spring 41 pushes the limiting steel ball 42 into the limiting hole 31 of the limiting disk 3. When the rotating sleeve 2 rotates, the limiting steel ball 42 switches between different limiting holes 31. The rotation angle is positioned through the elastic cooperation between the limiting disk 3 and the positioning component 4, providing a clear gear feel and preventing the handle 5 from shaking at the gear position.

[0019] The handle 5 is sleeved on the outside of the rotating sleeve 2 and is circumferentially limited to the rotating sleeve 2. The handle 5 is connected to the rotating sleeve 2 via a connector 6. In this embodiment, the connector 6 is specifically a bolt, which passes through the side wall of the rotating sleeve 2 and is screwed to the handle 5, thus reliably fixing the handle 5 to the rotating sleeve 2. The circumferential limitation between the handle 5 and the rotating sleeve 2 is achieved using known methods such as a non-circular cross-section or a keyed connection.

[0020] The actuating element 7 and the rotating sleeve 2 work together to lock or unlock the door / window. In this embodiment, the actuating element 7 is a square rod 71, which passes through the inner hole of the rotating sleeve 2. A second spring 72 is provided between the end of the square rod 71 and the end of the connecting piece 6 (i.e., bolt) of the handle 5. The elastic force of the second spring 72 controls the axial position of the square rod 71 within the rotating sleeve 2, allowing the square rod 71 to adaptively adjust its extension length to meet the installation requirements of door and window profiles of different thicknesses.

[0021] During installation, the rotating sleeve 2, limiting plate 3, positioning component 4, handle 5, and actuating component 7 are first pre-assembled onto the mounting base 1 to form a pre-assembled component; then the pre-assembled component is fixed as a whole onto the door and window profile. The square rod 71 adaptively adjusts its extension length under the action of the second spring 72, eliminating the need for on-site cutting of the square rod 71, making installation very convenient.

[0022] Example 2: As Figures 6 to 7 As shown, the difference between this embodiment and Embodiment 1 lies in the structural form of the actuating element 7. In this embodiment, the actuating element 7 is a fork 73, which is slidably mounted on the mounting base 1. The fork 73 is provided with a rack 74, and the outer ring of the rotating sleeve 2's turntable 22 is provided with meshing teeth 75 that mesh with the rack 74. When the rotating sleeve 2 rotates, the meshing transmission between the meshing teeth 75 and the rack 74 drives the fork 73 to slide linearly, realizing the linear drive of the door and window lock point and completing the locking or unlocking action. The other structures of this embodiment are the same as those of Embodiment 1, and will not be described again here.

[0023] As another alternative implementation of the connector 6, the connector 6 can also adopt a combination structure of a pin and a pin. The pin extends through the rotating sleeve 2 into the handle 5, and the pin is set on the handle 5 with its inner end abutting against the pin. This can also achieve a reliable connection between the handle 5 and the rotating sleeve 2. This alternative method is suitable for the installation requirements of handles 5 with different structural sizes.
