Description

Technical Field

[0001] This application relates to the field of door and window handle technology, and in particular to a door and window handle that can rotate in any direction. Background Technology

[0002] In daily life, for the convenience of opening and closing doors and windows, door and window handles are usually installed on them. Existing door and window handles include a handle, a mounting base, and a drive shaft. The mounting base is fixed to the door or window with bolts. One end of the drive shaft is connected to the lock installed on the door or window, and the other end of the drive shaft passes through the mounting base and is inserted into the handle. When you need to open the door or window, you only need to turn the handle to make the drive shaft rotate, which will open the lock inside the door or window, thus allowing the door or window to be opened.

[0003] Existing door and window handles are generally installed in a fixed direction, supporting only one installation direction. They cannot be adjusted after installation, which makes it impossible for users to adjust them according to their own preferences, resulting in inconvenience and affecting the convenience of using door and window handles. To address this, a door and window handle that can rotate in any direction is provided. Summary of the Invention

[0004] The purpose of this application is to provide a door and window handle that can rotate in any direction.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a door and window handle that can rotate in any direction, including a fixed base, a drive shaft movably connected inside the fixed base, a rotating sleeve fixedly connected to the right side of the drive shaft, a protective plate placed on the left side of the fixed base, a handle movably connected to the left side of the drive shaft, a fixing device threaded inside the handle, the fixing device including a screw threadedly connected inside the handle, a pressure block fixedly connected to one end of the screw near the inside of the handle, an anti-slip sleeve fixedly connected to the outside of the pressure block, a tightening block fixedly connected to one end of the screw away from the handle, a guide post fixedly connected inside the tightening block, a limiting sleeve movably connected to the outside of the guide post, a compression spring fixedly connected between the tightening block and the limiting sleeve, a pressure sleeve fixedly connected to the side of the limiting sleeve away from the compression spring, and an anti-slip pad fixedly connected to the side of the pressure sleeve away from the limiting sleeve.

[0006] As a preferred embodiment, the fixing base includes a base body, the interior of which is provided with a fixing hole, the exterior of which is provided with a slot, and a limit post is fixedly connected to the right side of the base body.

[0007] As another preferred embodiment, the rotating sleeve includes a sleeve body fixedly connected to the right side of the drive shaft, a push pin fixedly connected to the top of the sleeve body, and stops fixedly connected to both sides of the top of the sleeve body.

[0008] Further preferably, the drive shaft includes a rotating column movably connected inside the fixed base, the rotating column having a slot inside, a shaft body fixedly connected to the right side of the rotating column, and a torque spring movably sleeved on the outer side of the rotating column.

[0009] In a further preferred embodiment, the protective disc includes a disc body placed on the left side of the fixed base, a connecting block fixedly connected to the right side of the disc body, and a retaining strip fixedly connected to the inner side of the connecting block.

[0010] More preferably, the handle includes a rotating cylinder movably connected to the left side of the drive shaft, with a handle body fixedly connected to the outside of the rotating cylinder, and a rotating groove provided inside the rotating cylinder.

[0011] Compared with the prior art, the beneficial effects of this application are as follows:

[0012] This invention, by incorporating a fixing device, facilitates adjustment of the handle's direction. Tightening the screw block allows the screw to rotate, and the forward and reverse rotation of the screw enables it to move back and forth inside the rotating cylinder. When the screw moves towards the drive shaft, it drives the pressure block, pressing the anti-slip sleeve into the slot. Because the anti-slip sleeve has a frustum-shaped structure, the slot and anti-slip sleeve are perfectly matched. After the anti-slip sleeve is pressed into the slot, both the outer side of the anti-slip sleeve and the side near the drive shaft can fit against the rotating post, increasing the friction between the anti-slip sleeve and the rotating post. This, in turn, prevents the fixing device and the drive shaft from rotating relative to each other. This prevents the drive shaft and handle from rotating relative to each other. Simultaneously, when the anti-slip sleeve is pressed into the slot, the compression spring causes the anti-slip pad to press against the rotating cylinder, preventing the screw block from rotating easily. This further ensures that the drive shaft and handle cannot rotate relative to each other, guaranteeing that the rotating cylinder can drive the drive shaft to open the door or window when the handle is turned. After loosening the screw, the rotating cylinder can rotate relative to the rotating column and can rotate arbitrarily, allowing the handle to be rotated in any direction for use, facilitating adjustment according to the user's preferences. After adjustment, the screw can be tightened again to fix the handle and drive shaft. Attached Figure Description

[0018] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0021] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0022] like Figure 1-4The illustrated door and window handle, which can rotate in any direction, includes a fixed base 1. A drive shaft 3 is movably connected inside the fixed base 1. A rotating sleeve 2 is fixedly connected to the right side of the drive shaft 3. A protective disc 4 is placed on the left side of the fixed base 1. A handle 5 is movably connected to the left side of the drive shaft 3. A fixing device 6 is threadedly connected inside the handle 5. The fixing device 6 includes a screw 607 threadedly connected inside the handle 5. A rotating cylinder 502 has a threaded groove inside that matches the outer side of the screw 607. A pressure block 608 is fixedly connected to the end of the screw 607 near the inside of the handle 5. An anti-slip sleeve 609 is fixedly connected to the outer side of the pressure block 608. A tightening block 609 is fixedly connected to the end of the screw 607 away from the handle 5. 1. A guide post 605 is fixedly connected inside the screw block 601. The guide post 605 guides the movement of the limiting sleeve 602 and prevents the limiting sleeve 602 from rotating. The limiting sleeve 602 is movably connected to the outer side of the guide post 605. A compression spring 606 is fixedly connected between the screw block 601 and the limiting sleeve 602. The compression spring 606 is in a compressed state. A pressure sleeve 603 is fixedly connected to the side of the limiting sleeve 602 away from the compression spring 606. An anti-slip pad 604 is fixedly connected to the side of the pressure sleeve 603 away from the limiting sleeve 602. The anti-slip pad 604 and the anti-slip sleeve 609 are made of rubber. Tightening the screw block 601 allows the screw 607 to rotate, and the screw 607 rotates. The forward and reverse rotation of screw 607 allows it to move back and forth inside the rotating drum 502. When screw 607 moves towards the drive shaft 3, it drives the pressure block 608, pressing the anti-slip sleeve 609 into the slot 302. Since the anti-slip sleeve 609 has a frustum-shaped structure, the slot 302 fits perfectly. After the anti-slip sleeve 609 is pressed into the slot 302, both its outer side and the side near the drive shaft 3 can fit against the rotating post 301, increasing the friction between them. This prevents the fixing device 6 and the drive shaft 3 from rotating relative to each other, and consequently, prevents the drive shaft 3 and the handle 5 from rotating relative to each other. Meanwhile, when the anti-slip sleeve 609 is pressed into the slot 302, the anti-slip pad 604 can be pressed onto the rotating cylinder 502 under the action of the compression spring 606, thus preventing the screw block 601 from rotating easily. This further ensures that the drive shaft 3 and the handle 5 cannot rotate relative to each other, ensuring that when the handle body 501 is turned, the rotating cylinder 502 can drive the drive shaft 3 to rotate and open the door and window. After loosening the screw 607, the rotating cylinder 502 can rotate relative to the rotating column 301 and can rotate arbitrarily, so that the handle 5 can be rotated to any direction for use, which is convenient to adjust according to the user's preferences. After the adjustment is completed, the screw 607 can be tightened again to fix the handle 5 and the drive shaft 3.

[0023] Furthermore, the fixing seat 1 includes a seat body 101, the interior of which is provided with a fixing hole 102 for bolts to pass through and for fixing the seat body 101 to the door or window. The outer side of the seat body 101 is provided with a slot 103, and a limiting post 104 is fixedly connected to the right side of the seat body 101. The limiting post 104 is used to limit the rotation of the sleeve 201.

[0024] Furthermore, the rotating sleeve 2 includes a sleeve body 201 fixedly connected to the right side of the drive shaft 3. A lever 203 is fixedly connected to the top of the sleeve body 201. The limiting post 104 and the lever 203 are both located between the two ends of the torque spring 303. When the drive shaft 3 rotates, it drives the sleeve body 201, causing the lever 203 to push one end of the torque spring 303. After the external force is removed, the sleeve body 201 can return to its original position under the action of the torque spring 303, thereby driving the drive shaft 3 to return the handle 5 to its original position. Both sides of the top of the sleeve body 201 are fixedly connected to the stop blocks 202. When the drive shaft 3 drives the sleeve body 201 to rotate, the stop blocks 202 will also rotate. When the stop blocks 202 rotate to a certain angle, they will be blocked by the limiting post 104 to limit the rotation angle of the sleeve body 201, so that the handle 5 cannot continue to rotate after rotating to a certain angle, preventing the lock from being easily damaged due to excessive rotation angle.

[0025] Furthermore, the drive shaft 3 includes a rotating column 301 movably connected inside the fixed base 1. The rotating column 301 has a slot 302 inside, which is used for the insertion of the pressure block 608 and the anti-slip sleeve 609. A shaft body 304 is fixedly connected to the right side of the rotating column 301, and a torque spring 303 is movably sleeved on the outside of the rotating column 301. The torque spring 303 is used to reset the handle 5.

[0026] Furthermore, the protective disc 4 includes a disc body 401 placed on the left side of the fixing base 1. A connecting block 402 is fixedly connected to the right side of the disc body 401. A retaining strip 403 is fixedly connected to the inner side of the connecting block 402. The retaining strip 403 is made of rubber. By squeezing, the retaining strip 403 can be deformed, thereby pressing the retaining strip 403 into the retaining groove 103, thereby fixing the disc body 401 and covering the fixing hole 102 to ensure better overall aesthetics of the door and window.

[0027] Furthermore, the handle 5 includes a rotating cylinder 502 movably connected to the left side of the drive shaft 3. The outer side of the rotating cylinder 502 is fixedly connected to the handle body 501. The interior of the rotating cylinder 502 is provided with a rotating groove 503, which is used for the rotating cylinder 502 to rotate on the outside of the rotating column 301.

[0028] Working principle: During use, the base 101 is fixed to the door or window through the fixing hole 102, and then the protective plate 4 is covered. By turning the screw block 601, the screw 607 can be rotated. The forward and reverse rotation of the screw 607 allows it to move back and forth inside the rotating cylinder 502. When the screw 607 moves towards the drive shaft 3, it drives the pressure block 608, pressing the anti-slip sleeve 609 into the slot 302. Since the anti-slip sleeve 609 has a frustum-shaped structure, the slot 302 is compatible with the anti-slip sleeve 609. After the anti-slip sleeve 609 is pressed into the slot 302, both the outer side and the side near the drive shaft 3 of the anti-slip sleeve 609 can fit against the rotating post 301, increasing the friction between the anti-slip sleeve 609 and the rotating post 301, thereby improving the fixing... Device 6 and drive shaft 3 cannot rotate relative to each other, which in turn prevents drive shaft 3 and handle 5 from rotating relative to each other. At the same time, when anti-slip sleeve 609 is pressed into slot 302, the anti-slip pad 604 can press on the rotating cylinder 502 under the action of compression spring 606, which prevents screw block 601 from rotating easily. This further ensures that drive shaft 3 and handle 5 cannot rotate relative to each other, ensuring that when handle body 501 is turned, rotating cylinder 502 can drive drive shaft 3 to rotate and open doors and windows. After loosening screw 607, rotating cylinder 502 can rotate relative to rotating column 301 and can rotate arbitrarily, so that handle 5 can be rotated to any direction for use, which is convenient to adjust according to user preferences. After adjustment, screw 607 can be tightened again to fix handle 5 and drive shaft 3.
