Description

Technical Field

[0001] This utility model relates to the field of window and door handle technology, specifically a window and door positioning handle. Background Technology

[0002] Window and door handles are crucial operating components in door and window systems. Users turn the handle to drive the transmission mechanism, enabling the locking and unlocking of doors and windows. However, many existing window and door handles suffer from the following shortcomings: First, the handle body and internal transmission components (such as the square core and shift fork) are often tightly fixed or connected by riveting. When internal components wear out, break, or need replacement, disassembly is extremely inconvenient, sometimes requiring damage to the handle or assistance from professionals, resulting in high maintenance costs and low efficiency. Second, traditional handles lack clear feedback during rotation, offering no distinct "click" or tactile feedback, leading to a poor user experience and an inability to intuitively perceive whether the door or window is fully locked or open to a specific position.

[0003] Therefore, there is an urgent need for a new type of handle that is easy to disassemble and maintain and can provide excellent operating feel. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a window and door positioning handle that enables quick disassembly and maintenance of internal components, while providing a clear sense of positioning during rotation, thus enhancing the user experience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a window and door positioning handle, including a handle, an inner cavity of which is provided with a mounting base, an inner cavity of which is slidably fitted with a bushing, a connecting hole corresponding to the side wall of the mounting base and the side wall of the bushing, a fixing screw threadedly connected to the side wall of the handle, and the inner end of the fixing screw passing through the connecting hole of the mounting base and the bushing in sequence to fix the mounting base and the bushing relatively in the handle; The mounting base is provided with at least one set of elastic positioning components, the elastic positioning components include a spring and a steel ball, the mounting base is provided with a receiving hole, the spring is disposed in the receiving hole, one end of the spring abuts against the bottom wall of the receiving hole, and the other end abuts against the steel ball, causing the steel ball to partially protrude from the inner cavity wall of the mounting base; One end of the bushing is movably fitted with a positioning piece. The side surface of the positioning piece facing the mounting base has a steel ball groove that matches the steel ball. When the bushing is fitted with the positioning piece, the steel ball is partially embedded in the steel ball groove under the elastic force of the spring.

[0006] Preferably, the positioning piece is located inside the handle's cavity and flush with the handle's port. This design results in a better overall appearance and a more compact structure.

[0007] Preferably, the inner cavity of the bushing is provided with a rotating shaft, which passes through the inner cavity of the positioning piece and extends to the outside for driving door and window locks.

[0008] Preferably, the tops of the mounting base and the bushing are connected by a connecting screw. This design allows the mounting base and the bushing to rotate synchronously, facilitating assembly and ensuring the normal operation of the elastic positioning component.

[0009] Preferably, the inner cavity of the handle is adapted to the mounting base, preferably in a non-circular fit, to achieve circumferential limiting and ensure that the handle can effectively drive the mounting base to rotate.

[0010] This utility model provides a window and door positioning handle. Compared with the prior art, it has the following advantages: 1. This window and door positioning handle uses fixing screws to lock the core components such as the mounting base and bushing inside the handle. When it is necessary to inspect or replace internal parts, simply loosen the fixing screws to pull the entire internal component out from the rear of the handle. There is no need to remove the handle base (positioning plate) from the door or window, which greatly simplifies the maintenance process and reduces maintenance costs and time.

[0011] 2. This window and door positioning handle uses a spring to press a steel ball, which engages with a steel ball groove on the positioning plate. When the handle is turned, the steel ball slides on the surface of the positioning plate and periodically falls into the steel ball groove, producing a distinct "click" sound and a tactile feedback. This not only provides a pleasant operating feel but also gives users clear feedback on the lock / open status of the door or window.

[0012] 3. The window and door positioning handle is secured to the bushing with connecting screws, ensuring effective torque transmission. At the same time, the matching design between the handle's inner cavity and the mounting base prevents slippage, making the entire transmission process stable and reliable.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 5 This utility model provides a technical solution: a window and door positioning handle, which includes a handle 1, a positioning plate 2, a rotating shaft 3, a mounting base 4, a fixing screw 5, a connecting screw 6, a spring 7, a steel ball 8, and a bushing 9. The positioning plate 2 is used to be fixedly installed on the door and window profile by screws, and the rotating shaft 3 is used to drive the door and window locking point or locking seat.

[0017] The handle 1 has an inner cavity whose shape is adapted to the outer shape of the mounting base 4, preferably non-circular (such as D-shaped or square) to achieve circumferential limiting of the mounting base 4 and prevent it from rotating in the inner cavity, and the mounting base 4 is fixedly housed in the inner cavity.

[0018] The inner cavity of the mounting base 4 is slidably fitted with a bushing 9. The top of the mounting base 4 and the top of the bushing 9 are threadedly connected by a connecting screw 6 to fix them together and allow them to rotate synchronously. The side walls of the mounting base 4 and the bushing 9 are respectively provided with connecting holes. The side wall of the handle 1 is threadedly connected with a fixing screw 5. The inner end of the fixing screw 5 passes through the connecting holes on the side walls of the mounting base 4 and the bushing 9 in sequence. By tightening the fixing screw 5, the mounting base 4 and the bushing 9 can be fixed and locked in the handle 1. By loosening the fixing screw 5, the entire internal components (mounting base 4, bushing 9, etc.) can be removed from the handle 1, realizing quick disassembly and maintenance.

[0019] At least one set of elastic positioning components is provided inside the mounting base 4. In this embodiment, two sets of elastic positioning components are symmetrically arranged. Each set of elastic positioning components includes a spring 7 and a steel ball 8. The mounting base 4 is provided with a corresponding receiving hole. The spring 7 is housed in the receiving hole, with one end abutting against the bottom wall of the receiving hole and the other end abutting against the steel ball 8, thereby continuously driving the steel ball 8 to partially protrude from the inner cavity wall of the mounting base 4.

[0020] One end of the bushing 9 is movably fitted with a positioning piece 2. The side surface of the positioning piece 2 facing the mounting base 4 has multiple steel ball grooves 10 that are adapted to the steel balls 8. When the bushing 9 is fitted onto the positioning piece 2 and the entire handle is installed in place, the steel balls 8 will be partially embedded in one of the steel ball grooves 10 on the positioning piece 2 under the elastic force of the spring 7.

[0021] The positioning plate 2 is installed in the inner cavity of the handle 1, and its outer end face is flush with the port end face of the handle 1, making the appearance neat and beautiful. The rotating shaft 3 passes through the center hole of the positioning plate 2 and the inner cavity of the bushing 9 in sequence, and extends outward. The cross section of the inner cavity of the bushing 9 matches the cross section of the rotating shaft 3 (for example, both are square), so that when the bushing 9 rotates, it can effectively drive the rotating shaft 3 to rotate synchronously.

[0022] During assembly: First, insert the spring 7 and steel ball 8 into the receiving hole of the mounting base 4 to form an elastic positioning assembly. Next, put the positioning piece 2 on the bushing 9. Then, insert the bushing 9 into the inner cavity of the mounting base 4 and connect the two from the top using the connecting screw 6. At this time, the steel ball 8 in the mounting base 4 is located in the steel ball groove 10 under the action of the spring 7 and presses against the positioning piece 2. Then, put the assembly of the mounting base 4 and bushing 9 into the inner cavity of the handle 1 and align the connecting holes on the side walls of the mounting base 4 and bushing 9. Screw the fixing screw 5 from the side wall of the handle 1 so that it passes through the connecting holes of the two in sequence, thereby firmly installing the internal components in the handle 1. Finally, pass the rotating shaft 3 through the positioning piece 2 and insert it into the inner cavity of the bushing 9.

[0023] During operation: When the user turns the handle 1, the handle 1 is fixedly connected by the fixing screw 5 and the connecting screw 6, which drives the mounting base 4 and the bushing 9 to rotate synchronously. The bushing 9 ultimately drives the rotating shaft 3 to rotate, realizing the unlocking or locking. During this rotation, since the positioning piece 2 is fixed, the steel ball 8 in the mounting base 4 will slide relative to the surface of the positioning piece 2. When the handle 1 is turned to a specific angle (that is, when the steel ball 8 is aligned with the next steel ball groove 10), the steel ball 8 will quickly embed into the steel ball groove 10 under the elastic force of the spring 7, producing a clear "click" sound and positioning sense, thus providing clear gear indication and excellent operating feel. To continue turning the handle 1, the spring force needs to be overcome to make the steel ball 8 roll out of the steel ball groove 10. This process is repeated to realize multi-gear positioning.

[0024] During disassembly and maintenance: simply loosen the fixing screw 5 on the side wall of handle 1 to pull the core components such as mounting base 4, bushing 9, and positioning plate 2 out of handle 1 as a whole, and remove the connecting screw 6 to facilitate the inspection or replacement of any internal parts, greatly improving the convenience of maintenance.
