[0002] Window handles are an important component of door and window hardware. They not only function as operating parts for opening and closing doors and windows but also serve a decorative purpose. Window handles typically consist of a handle, a base, and connectors, and are installed on the door or window sash for user convenience.

[0003] The base, an important installation component of window handles, is usually made of non-metallic materials. Although it is lightweight and cost-effective, its service life is limited. At the same time, current window handles cannot withstand high torque, making it difficult for users to open and close them quickly, which limits their use.

[0004] In conclusion, how to provide a window handle that can withstand greater torque and open and close more smoothly is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a window handle that can improve the smoothness of the opening and closing process by distributing torque.

[0008] Holding hands and holding hands head;

[0009] A base, wherein a groove is provided on the base, and the handle head protrudes through the groove from the base and is connected to the handle;

[0010] A positioning element is located inside the groove and is connected to the handle head. The positioning element has a plurality of positioning protrusions for dispersing torque.

[0011] The upper cover is located between the base and the handle, and is connected to the base.

[0012] Furthermore, the positioning element of this invention is annular and has a wave-shaped structure.

[0013] Furthermore, the present invention provides that the number of the plurality of positioning protrusions is four, and they are evenly distributed around the circumference of the positioning member axis, with each of the four positioning protrusions located at the crest position on the side of the positioning member closer to the base.

[0014] Furthermore, the bottom of the groove is provided with four arc-shaped damping protrusions, and the four damping protrusions are evenly distributed around the circumference of the positioning member axis.

[0015] When the four positioning protrusions are respectively located in the gaps between the four damping protrusions, the damping protrusions and the positioning protrusions form a closed annular structure.

[0016] Furthermore, in this invention, the contact points of the damping protrusion and the positioning protrusion are both provided with rounded corners.

[0017] Furthermore, the present invention provides a boss on the side of the handle head near the base, and a plurality of limiting grooves are provided on the boss. The positioning member is provided with a plurality of limiting protrusions corresponding to the limiting grooves. The plurality of limiting grooves and the plurality of limiting protrusions are evenly distributed along the axis of the positioning member.

[0018] Furthermore, in this invention, each of the plurality of limiting protrusions and the plurality of limiting grooves includes a semi-circular structure and an arc-shaped structure, and are arranged alternately.

[0019] Furthermore, the base of this invention is made of an oxidizable alloy material.

[0020] Furthermore, the positioning element is made of polyoxymethylene.

[0021] Furthermore, this utility model also includes:

[0033] 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.

[0034] The core of this invention is to provide a window handle that can improve the smoothness of the opening and closing process by distributing torque.

[0035] Please refer to Figures 1-5A window handle includes a handle 1, a handle head 2, a base 3, a positioning element 4, and a top cover 6. The base 3 has a groove 301. The handle head 2 passes through the groove 301 and is connected to the handle 1. The positioning element 4 is located inside the groove 301 and is connected to the handle head 2. The positioning element 4 has a plurality of positioning protrusions 401 for distributing torque. The top cover 6 is located between the base 3 and the handle 1 and is connected to the base 3.

[0036] It should be noted that the material of the base 3 is not limited in this embodiment of the utility model. The base 3 can be made of any formable rigid material, such as plastic, ceramic or metal.

[0037] Optionally, the base 3 in this embodiment of the present invention can be made of an oxidizable alloy material. By utilizing the properties of the material, its surface can be oxidized under specific conditions to form a protective layer, thereby increasing the overall service life of the product.

[0038] Optionally, in this embodiment of the present invention, the connection between the upper cover 6 and the base 3 can be achieved by an interference fit. In some embodiments, specifically, the base 3 is provided with a flange that matches the shape of the upper cover 6. The connection between the upper cover 6 and the base 3 is achieved by the upper cover 6 being locked in the corresponding flange position.

[0039] In other embodiments, the base 3 and the top cover 6 can be connected by bolts or snap-fit ​​to make them detachable, so as to facilitate the repair and replacement of the product.

[0040] In use, the base 3 has a groove 301, and a through hole at the bottom of the groove 301. The handle head 2 passes through the groove 301 and is connected to the handle 1. The top cover 6 is located between the base 3 and the handle 1 and is connected to the base 3. The top cover 6 seals the base 3 and improves its aesthetics. The positioning element 4 is located inside the groove 301 and is connected to the handle head 2. The positioning element 4 has several positioning protrusions 401 for dispersing torque. That is, the positioning element 4 is connected to the handle head 2. When the handle 1 and the handle head 2 rotate, the positioning element 4 will rotate with it. Therefore, the positioning protrusions 401 on the positioning element 4 move with it. On the one hand, the contact force between the positioning element 4 and the base 3 is increased by squeezing, thereby offsetting the need for continuous large torque to rotate the handle 1, making the operation of the user smoother when opening and closing the window. On the other hand, it can reduce and buffer the resistance of the product when opening and closing the window, effectively eliminating vibration and reducing noise.

[0041] Please refer to Figure 1 In some embodiments, the positioning element 4 is annular, which facilitates its cooperation with the handle head 2 and better adapts to the purpose of the positioning element 4 rotating with the handle head 2.

[0042] Specifically, the handle head 2 includes an installation part, which is arc-shaped. The positioning part 4 is fitted onto the installation part on the handle head 2 to realize the installation of the positioning part 4.

[0043] Please refer to Figures 1-5 In some embodiments, the bottom of the groove 301 is provided with four arc-shaped damping protrusions 303, which are evenly distributed around the circumference of the positioning member 4. The number of the positioning protrusions 401 is four, which are also evenly distributed around the circumference of the positioning member 4. Specifically, there are four damping protrusions 303 and four positioning protrusions 401. When the four positioning protrusions 401 are respectively located in the gaps between the four damping protrusions 303, the damping protrusions 303 and the positioning protrusions 401 form a closed annular structure. That is to say, during the rotation of the positioning member 4, the positioning protrusions 401 will disengage from the gaps between the damping protrusions 303, thereby forming a squeeze between them to achieve the purpose of dispersing torque, reducing the force required by the user when using the product to switch it on and off, and making it convenient for the user to use.

[0044] Alternatively, in some embodiments, the damping protrusion 303 may be fixed in an integral manner with the base 3.

[0045] In other embodiments, the damping protrusion 303 may be made of other materials and fixed to the base 3 by snap-fit, bolt or adhesive.

[0046] Please refer to Figures 1-5 To further improve the smoothness of the product during switching, in some embodiments, the positioning element 4 adopts a wave-shaped structure. That is, the positioning element 4 adopts a wave-shaped structure on the basis of a circular ring. Through the wave-shaped structure, the smoothness of the positioning element 4 is improved when it rotates with the handle head 2. Furthermore, the four positioning protrusions 401 are all located at the crest of the wave on the side of the positioning element 4 near the base 3. By limiting the position of the positioning protrusions 401, when they enter the gap of the damping protrusions 303, the stability of the fit between the damping protrusions 303 is increased, avoiding the positioning element 4 from over-rotating. Moreover, after the positioning protrusions 401 leave the gap of the damping protrusions 303, at the crest of the wave, the squeezing effect between them and the damping protrusions 303 can be further strengthened, which is conducive to further increasing the dispersion of torque and improving the smoothness of the user's rotation process.

[0047] Optionally, in this embodiment of the invention, the wave crests of the wave-shaped positioning member 4 can be set to four and evenly distributed along the axis of the positioning member 4.

[0048] Optionally, in this embodiment of the present invention, the positioning protrusion 401 can be integrally formed with the positioning member 4, and the positioning protrusion 401 adopts an arc-shaped structure that cooperates with the positioning member 4, so as to ensure the tightness of the cooperation with the damping protrusion 303.

[0049] Optionally, in order to make it easier for the positioning protrusion 401 to disengage from the damping protrusion 303, in some embodiments, the contact points of the damping protrusion 303 and the positioning protrusion 401 are provided with rounded corners. Specifically, rounded corners or chamfers are provided at the contact points of the positioning protrusion 401 and the damping protrusion 303, and rounded corners or chamfers are provided at the contact points of the damping protrusion 303 and the positioning protrusion 401, which helps to further improve the smoothness of the handle 1 when rotating.

[0050] Please refer to Figures 1-5 In order to quickly fix the positioning member 4 and the handle head 2 relative to each other, in some embodiments, the handle head 2 is provided with a boss 201 on the side near the base 3. The boss 201 is provided with a number of limiting grooves 202, and the positioning member 4 is provided with a number of limiting protrusions 402 corresponding to the limiting grooves 202. The number of limiting grooves 202 and the number of limiting protrusions 402 are evenly distributed along the axis of the positioning member 4. That is to say, by using a number of limiting grooves 202 and a number of limiting protrusions 402 to cooperate, when the limiting protrusions 402 on the positioning member 4 are engaged with the limiting grooves 202 on the boss 201, the relative fixation between the positioning member 4 and the handle head 2 is achieved, so that the positioning member 4 can rotate with the handle head 2.

[0051] Optionally, in the above embodiments, the boss 201 and the handle head 2 are integrally formed.

[0052] Please refer to Figures 1-5 In order to improve the stability of the connection between the positioning member 4 and the handle head 2, in some embodiments, several limiting protrusions 402 and several limiting grooves 202 each include a semi-circular structure and an arc-shaped structure, and are arranged alternately. That is, several limiting protrusions 402 and several limiting grooves 202 each include two types of structures, and both types of structures include a semi-circular structure and an arc-shaped structure. At the same time, the two types of structures are arranged alternately to improve the positioning member 4's ability to maintain effective and firm stability when receiving torque force during the rotation of the handle head 2, and to avoid slippage.

[0053] Optionally, in some embodiments, the semi-circular structure and the positioning protrusion 401 are fixed on the same axial position as the positioning member 4. Therefore, when the positioning protrusion 401 slides between the damping protrusion 303, sliding will occur along the axial direction of the positioning member 4. The limiting protrusion 402 and the limiting groove 202 of the semi-circular structure cooperate to accommodate the relative sliding of the positioning protrusion 401, thereby further improving the stability of the positioning member 4 during use.

[0054] Optionally, in some embodiments, the positioning element 4 is made of polyoxymethylene, which gives the part the self-lubricating properties, excellent wear resistance and long-lasting fatigue strength required in specific working conditions. The material's elasticity and the perfect combination with the part's waveform structure design enable the positioning element 4 to maintain good usability in countless working frequencies.

[0055] In some embodiments, the device also includes an anti-wear ring 7 and a compression spring 5. There are two anti-wear rings 7, which are located on both sides of the upper cover 6 respectively. The anti-wear rings 7 are used to support the handle 1 and the upper cover 6 during relative rotation, reduce wear, and reduce the shaking during the rotation of the handle 1. The compression spring 5 is installed between the upper cover 6 and the handle 1. The compression spring 5 can provide a certain preload between the handle 1 and the upper cover 6, which is beneficial to further reduce the shaking during use.

[0056] In other words, the key point of this utility model is that: the base 3 is provided with a groove 301, and a through hole is provided at the bottom of the groove 301 to pass through the base 3. The handle head 2 passes through the groove 301 to exit the base 3 and is connected to the handle 1. The upper cover 6 is located between the base 3 and the handle 1 and is connected to the base 3. The upper cover 6 closes the base 3 and improves the aesthetics of the base 3. The positioning member 4 is located inside the groove 301 and is connected to the handle head 2. The positioning member 4 is provided with several positioning protrusions 401 for dispersing torque. That is to say, the positioning member 4 is connected to the handle head 2. When the handle 1 and the handle head 2 rotate, the positioning member 4 will rotate with it. Therefore, the several positioning protrusions 401 on the positioning member 4 move with it. On the one hand, the contact force between the positioning member 4 and the base 3 is increased by squeezing, thereby offsetting the need for continuous large torque to rotate the handle 1, making the operation of the user smoother during the opening and closing of the window. On the other hand, the resistance of the product during the opening and closing of the window is reduced and buffered, effectively eliminating vibration and reducing noise.

[0057] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0058] The above provides a detailed description of a window handle provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
