Description

Technical Field

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

[0002] In the field of door and window hardware, a common solution for achieving multi-position rotational positioning of handles is to use a "gear-ball" meshing structure. For example, CN118029770A discloses such a typical structure as a "door and window handle". This handle has a transmission gear and two second receiving cavities arranged symmetrically at 180° in its base. A ball is pressed against each cavity by a second spring. During operation, rotating the handle drives the transmission gear to rotate, and the balls are sequentially engaged in the gear teeth under the action of the spring, thus producing a positioning feel and audible feedback. Although this structure can achieve basic functions, its inherent drawback is that the transmission gear needs a sufficient diameter to machine the teeth, and the engagement of the balls and springs also requires a considerable radial space in the circumference of the base. This series of interacting parts results in a complex handle head structure, bulky size, and difficulty in reducing thickness, making it difficult to meet the design requirements of modern doors and windows for a slim and minimalist appearance. Utility Model Content

[0003] This utility model proposes a door and window handle structure that solves the technical problem that the bulky and excessively thick head structure of door and window handles cannot meet the requirements of modern thin door and window installation.

[0004] The technical solution of this utility model is implemented as follows: A door and window handle structure includes a handle and a connecting cover disposed on one side of the handle. The end of the handle is provided with a bushing, and a square shaft is provided through the bushing and extending outward from the connecting cover. A first positioning component is disposed between the connecting cover and the handle, and a second positioning component is disposed between the connecting cover and the bushing. An elastic element is fitted on the bushing, and the elastic element applies axial pressure to the second positioning component, so that the first positioning component and the second positioning component can alternately position and engage with the connecting cover when the handle is rotated.

[0005] Furthermore, the first positioning component includes a plurality of first protrusions disposed on the handle, the first protrusions being positioned in conjunction with a plurality of first grooves formed on the connecting cover.

[0006] Furthermore, the first positioning component also includes a first gasket disposed between the handle and the connecting cover, wherein the handle passes through a perforation formed in the first gasket via a first protrusion.

[0007] Furthermore, the second positioning component includes a second gasket disposed between the connecting cover and the bushing, the second gasket being positioned by the cooperation of a plurality of second protrusions with a plurality of second grooves opened on the connecting cover.

[0008] Furthermore, the connecting cover has a stepped groove recessed on the side facing the second gasket, and the second groove is formed on the side wall of the stepped groove.

[0009] Furthermore, the second gasket has a stepped structure adapted to the stepped groove.

[0010] Furthermore, the mating points of the first positioning component and the connecting cover are offset from the mating points of the second positioning component and the connecting cover in the circumferential direction.

[0011] Furthermore, the elastic element is a spring, and the bushing is provided with an anti-dislodgement protrusion for limiting one end of the spring, and the other end of the spring abuts against the second positioning component.

[0012] Furthermore, the handle and the bushing are rotatably connected by a pin.

[0013] Furthermore, the back of the connecting cover is provided with positioning protrusions for pre-positioning with door and window profiles and positioning holes for fastening.

[0014] The beneficial effects of the technical solution provided in this application are as follows: 1. This application overcomes the core defect of the bulky traditional gear-ball bearing handle structure by creating a collaborative positioning structure consisting of a first positioning component, a second positioning component, and an axially pressurized elastic element. This design abandons the traditional structure with its large radial dimensions and numerous parts, utilizing a novel mechanism where the two positioning components alternately engage with the connecting cover under the pressure of the elastic element, achieving an extremely flat and compact handle head structure. This significantly reduces the overall size of the handle, allowing it to easily adapt to narrow modern door and window profiles, while ensuring the reliable implementation of the rotation positioning function at the principle level. 2. In this application, by specifically optimizing the positioning component into a pad structure with protrusions and grooves, not only is precise gear positioning achieved with extremely simple components, but the thinness of the pad itself further compresses the axial space. In particular, the staggered arrangement of the first and second grooves in the circumferential direction makes the positioning points more densely distributed, significantly improving the adjustment accuracy and positioning stability of the handle rotation angle; 3. In this application, the cooperation between the spring and the anti-detachment protrusion provides a stable and continuous axial force for the separation and reset of the positioning component, ensuring a crisp and smooth operating feel and long-term reliability. Furthermore, the rotating connection design between the handle and the bushing effectively improves operating comfort; the pre-positioning protrusion and positioning hole on the connecting cover simplify the installation process and enhance the concealed aesthetic effect.

Detailed Implementation

[0018] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] This utility model relates to a door and window handle structure, such as Figure 1 As shown, its core components include a handle 1, a connecting cover 4, a first gasket 3, a second gasket 5, a bushing 7, and a spring 6. A bushing 7 is located at the end of the handle 1. This bushing passes sequentially through the first gasket 3, the connecting cover 4, and the second gasket 5, extending to a square shaft 8 for driving the door and window locking system. The innovation of the entire structure lies in the compact design of the handle structure achieved through the synergistic effect of two sets of positioning components and elastic elements.

[0020] The first positioning component is disposed between the handle 1 and the connecting cover 4, and achieves its positioning function through the direct engagement of multiple first protrusions 11 with multiple first grooves 41 formed on the connecting cover 4. Figure 2 As shown, these first protrusions 11 are disposed on the end face of the handle 1, and can be sequentially engaged in different first grooves 41 when the handle is rotated, providing clear positioning feedback.

[0021] In a preferred embodiment of the first positioning assembly, a first gasket 3 is disposed between the handle 1 and the connecting cover 4, and its main function is to provide stable support and connection. The first gasket 3 has multiple through holes 31 for the first protrusion 11 on the handle 1 to pass through. This design ensures that the first protrusion 11 can accurately engage with the first groove 41 on the connecting cover 4, while the first gasket 3 itself also reduces friction and protects the components.

[0022] In another feasible implementation, the first protrusion can be directly disposed on the first gasket 3, in which case the first gasket 3 is fixedly connected to the handle 1. With this configuration, when the handle 1 is rotated, the first protrusion fixed to the first gasket 3 rotates accordingly and directly engages with the first groove 41 on the connecting cover 4. This alternative solution also achieves precise positioning, demonstrating the flexibility of this invention.

[0023] The second positioning component is independent of the first positioning component. Its core includes a second gasket 5, multiple second protrusions 51 disposed on the second gasket 5, and multiple second grooves 43 formed on the connecting cover 4. For example... Figure 3 As shown, the second gasket 5 is disposed between the connecting cover 4 and the bushing 7, and the secondary positioning function is achieved through the cooperation of the second protrusion 51 and the second groove 43.

[0024] The connecting cover 4 has a stepped groove 42 recessed on the side facing the second gasket 5. The main function of this stepped groove is to provide a precise receiving space and mounting base for the second gasket 5. A second groove 43 is formed in the bottom or side wall of the stepped groove 42 and mates with the second protrusion 51. The structure of the stepped groove 42 ensures the stable positioning of the second gasket 5, preventing it from shifting during use, and also helps to reduce the axial dimension of the entire assembly.

[0025] The first positioning component and the second positioning component work together. The first groove 41 and the second groove 43 are staggered in position on the circumference of the connecting cover 4. When the handle 1 is rotated, the two sets of positioning components alternately engage with the connecting cover, which not only increases the effective positioning point density, making the angle adjustment more precise, but also brings a clearer and more stable operating feel.

[0026] The bushing 7 is equipped with an anti-detachment protrusion 71 and a spring 6, which serves as an elastic element, is fitted onto it. One end of the spring abuts against the anti-detachment protrusion, while the other end constantly presses against the second washer 5. This elastic system provides continuous and stable axial pressure for the second positioning assembly. Its core function is that when the handle rotates and the protrusion needs to cross the slope of the groove, the spring is compressed, allowing the second washer 5 to undergo slight axial displacement; when the protrusion slides into the next groove, the spring pressure ensures that it quickly resets and locks in place, thereby guaranteeing the reliability of positioning and a crisp "click" sound during operation.

[0027] The handle 1 and the bushing 7 are rotatably connected by a pin 2. This design allows the user to tilt the end of the handle 1 upwards at a slight angle during use, thereby increasing the operating space between the handle and the door / window profile, greatly improving the convenience and comfort of operation, and is particularly suitable for modern door and window systems with limited installation space.

[0028] The back of the connecting cover 4 has a positioning protrusion 44 for pre-positioning, which is a key feature. For example... Figure 1 As shown, its unique feature is a chamfered recess on one side near the main body of the connecting cover 4. During installation, a hole is initially drilled in the door / window profile, the positioning protrusion 44 is inserted into the hole, and then the main body of the connecting cover 4 is lifted upwards. At this time, the chamfered edge of the recess will engage with the edge of the profile hole, producing a slight displacement and locking effect, achieving initial positioning and anti-dislodgement functions. This recess can be located at the top or bottom of the positioning protrusion 44 according to design requirements.

[0029] After initial positioning via the positioning protrusion 44, final tightening is performed. The connecting cover 4 also features a positioning hole 45, through which screws are passed to secure it to the door / window profile, achieving a firm secondary positioning. For aesthetic purposes, the positioning hole 45 is preferably located on the lower part of the connecting cover 4. This design ensures that after the handle is installed, the positioning hole 45 and its fastening screws are not directly visible from the front or side, and the positioning protrusion 44 is completely hidden because it is inserted into the profile, ensuring a clean and complete appearance for the handle.

[0030] This invention, through the ingenious combination of an innovative dual-positioning component and a spring pressure system, coupled with a rotating handle connection and a concealed mounting structure for the connecting cover, successfully achieves an extremely flat and compact handle head structure while ensuring reliable rotational positioning. The synergistic effect of the components not only solves the core problem of the bulky traditional structure but also brings higher positioning accuracy, better operating feel, a simpler installation process, and a more aesthetically pleasing visual effect.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
