Description

Technical Field

[0001] The utility model belongs to the technical field of nut installation, and particularly relates to a handheld adjustable jacking nut installation sleeve. Background Art

[0002] Adjustable jacks are commonly used in formwork support. Their main rod is fully threaded, and the height of the jack can be adjusted by rotating a nut through the threads to achieve the desired support effect. In actual use, the nut is usually manually screwed into the threaded rod.

[0003] In existing technology, manual screwing of nuts is inefficient, and operator errors can make the nuts difficult to tighten, reducing installation efficiency. Adjusting adjustable support nuts can be time-consuming when multiple supports need to be adjusted simultaneously, potentially impacting work efficiency and progress. Manually adjusting each nut requires significant physical effort and labor, especially at height or inconvenient locations. Scaffolding regulations stipulate that the extended length of adjustable support screws should not exceed 300mm, and the insertion length into the vertical pole should not be less than 150mm. For workers, tightening nuts into the specified length range may require training, which can add additional time and cost. Furthermore, ensuring that each nut is adjusted to the correct height requires operator skill and experience; otherwise, quality issues may occur. Existing nut adjustment devices connect the support nut on one end and a handheld tightening gun on the other. During tightening, the nut can easily become disengaged from the tightening gun, making operation inconvenient. Operating adjustable support nuts at height poses a safety risk of falling or stumbling, requiring additional safety measures and precautions. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a handheld adjustable top support nut installation sleeve. The hexagonal nut is connected to an external device and rotated so that the rotating sleeve rotates and drives the nut fixed in the nut fixing groove on the top of it, so that the nut can be quickly screwed in by mechanical operation. Holding the fixed handle of the rotating sleeve can help the rotating sleeve to easily and quickly screw in the nut, which is more convenient to operate and saves time and cost, thereby solving the problems in the above background.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a handheld adjustable jacking nut mounting sleeve, including a fixed sleeve, a rotating sleeve rotatably connected inside the fixed sleeve, the rotating sleeve can rotate inside the fixed sleeve, a fixed handle is provided on one side of the outer wall of the fixed sleeve, a hexagonal nut is provided at one end of the rotating sleeve, and a replaceable connecting block is installed at the other end of the rotating sleeve, and a nut fixing groove is provided on the top of the connecting block.

[0006] Preferably, the top end of the rotating sleeve is provided with an external thread, one end of the connecting block is provided with a nut fixing groove, and the other end of the connecting block is provided with an internal thread matching the external thread.

[0007] Preferably, a nut fixing groove is fixedly provided on the top of the rotating sleeve.

[0008] Preferably, the nut fixing groove is a cylindrical structure, and a hexagonal cavity is provided on the central axis of the cylinder.

[0009] Preferably, the nut fixing groove is a circular tube structure, and a square opening is provided at the top of the circular tube.

[0010] Preferably, two limiting rings are provided on the rotating sleeve. The two limiting rings are respectively located at both ends of the rotating sleeve and are used to limit the movement range of the rotating sleeve in the fixed sleeve to ensure the stability and safety of the operation.

[0011] Preferably, an observation window is provided on the outer wall of the rotating sleeve.

[0012] Preferably, the fixed handle is provided with anti-slip textures.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention proposes a handheld adjustable top support nut installation sleeve, which is connected to the hexagonal nut through an external device and rotated to drive the rotating sleeve to rotate and drive the nut fixed in the nut fixing groove on its top, so that mechanical operation can be realized to quickly screw in the nut.

[0021] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are intended to illustrate the present invention but are not intended to limit the scope of the present invention. All other embodiments obtained by persons of ordinary skill in the art without creative effort are intended to fall within the scope of protection of the present invention.

[0022] Combine Figure 1 、 Figure 2 and Figure 3As shown, a handheld adjustable jacking nut installation sleeve includes a fixed sleeve 1, which is internally rotatably connected to a rotating sleeve 2. The rotating sleeve 2 can rotate within the fixed sleeve 1. A fixed handle 3 is provided on one side of the outer wall of the fixed sleeve 1. A hexagonal nut 6 is provided at one end of the rotating sleeve 2. A replaceable connecting block 4 is mounted on the other end of the rotating sleeve 2, and a nut fixing groove 5 is provided on the top of the connecting block 4. Specifically, a handheld adjustable jacking nut installation sleeve improves work efficiency and operational convenience and is used in situations where jacking nuts in large mechanical equipment need to be frequently installed or adjusted. The sleeve's sophisticated structure and versatility ensure efficient application in various working environments. The fixed sleeve 1, as the main body of the entire tool, is made of a high-strength alloy material, ensuring stability and durability under long-term use. Its interior is precisely machined to form a smooth rotating track to reduce frictional resistance of the rotating sleeve 2 during rotation and improve rotation efficiency. In addition, the outer surface of the fixed sleeve 1 is also designed with an anti-slip texture, which, together with the fixed handle 3, ensures that the user can hold it firmly even in a wet or oily environment. The rotating sleeve 2 is the core working component, which is connected to the inside of the fixed sleeve 1 through a precise bearing structure, achieving a smooth rotation movement. It is not only convenient for the user to easily rotate the nut, but also effectively disperses the force to avoid unnecessary damage to the nut. One end of the rotating sleeve 2 is designed with a standard hexagonal shape, namely a hexagonal nut 6, so that it can be rotated with an external drive mechanism (such as a wrench or power tool, etc.), thereby driving the sleeve to rotate and then tightening the nut. A detachable connecting block 4 interface is designed at the other end, providing users with a high degree of flexibility. As an extension of the rotating sleeve 2, the connecting block 4 is designed with full consideration of versatility and replaceability. Through a simple locking mechanism, users can easily replace connecting blocks of different specifications or functions to adapt to nuts of different shapes and sizes or special installation requirements. The nut retaining groove 5, built into the top of the connecting block 4 and made of a highly elastic material, tightly and securely grips the nut, preventing it from falling out during rotation and significantly improving operational safety. This handheld adjustable jacking nut installation sleeve, with its innovative design, efficient functionality, and user-friendly details, has revolutionized fields such as machinery maintenance and equipment installation, making it an indispensable and efficient tool in modern industry.

[0023] Combine Figure 3 、 Figure 4 and Figure 5As shown, the top of the rotating sleeve 2 is provided with an external thread 21, one end of the connecting block 4 is provided with a nut fixing groove 5, and the other end of the connecting block 4 is provided with an internal thread 41 that matches the external thread 21. Specifically, the external thread 21 at the top of the rotating sleeve 2 not only enhances the connection strength between the rotating sleeve 2 and the connecting block 4, but also ensures the stability and reliability of the connection. The external thread 21 is made of high-quality steel and is precision-machined. The surface is treated with a rust-proofing treatment to ensure long-term wear resistance and corrosion resistance. Its pitch and thread angle are carefully calculated, ensuring a tight and smooth connection between the rotating sleeve 2 and the connecting block 4, reducing operational problems caused by loosening or stripping. A nut fixing groove 5 is provided at one end of the connecting block 4 for fixing the nut. The shape and size of the nut fixing groove 5 precisely match the profile of various standard nuts, firmly clamping the nut and preventing slippage or misalignment during rotation. In addition, the interior of the nut fixing groove 5 may be coated with an anti-slip coating or made of an elastic material to provide a better fixation effect and prevent damage to the nut surface. The other end of the connecting block 4 is provided with an internal thread 41 that perfectly matches the external thread 21. The processing precision of the internal thread 41 is extremely high, ensuring that it can seamlessly dock with the external thread 21 of the rotating sleeve 2 to form a stable threaded connection. This connection method not only makes the installation and disassembly of the connecting block 4 easy and quick, but also allows the user to adjust the position of the connecting block 4 on the rotating sleeve 2 as needed to adapt to the installation requirements of nuts of different lengths or angles. In actual operation, the user only needs to align the internal thread 41 of the connecting block 4 with the external thread 21 of the rotating sleeve and gently rotate it to achieve a tight connection between the two. Once the connection is completed, the user can drive the connecting block 4 and the nut on it to rotate by rotating the sleeve 2 to complete the tightening or loosening of the nut. The whole process is efficient, convenient, safe and reliable, which greatly improves the efficiency and quality of the nut installation operation.

[0024] Combine Figure 1 and Figure 2As shown, a nut fixing groove 5 is fixedly provided on the top of the rotating sleeve 2. Specifically, the nut fixing groove 5 designed on the top of the rotating sleeve 2. Not only does it simplify the structure of the tool, but it also greatly improves the convenience and efficiency of use. The nut fixing groove 5 is fixed on the top of the rotating sleeve 2, and its position and shape have been precisely calculated and optimized to ensure that nuts of various specifications can be clamped stably and accurately. The nut fixing groove 5 is covered with anti-slip or elastic materials. These materials not only have good wear resistance and corrosion resistance, but can also effectively prevent the nut from slipping or dislocating during rotation, thereby ensuring the accuracy and reliability of nut installation. In addition, the design of the nut fixing groove 5 also fully considers the user's usage habits and needs. Its opening size is moderate, which makes it easy for the user to put the nut into the nut fixing groove 5 and rotate it by rotating the sleeve 2. The nut fixing groove 5 on the top of the rotating sleeve 2 is not an isolated design element, but is closely connected with other parts of the rotating sleeve 2 and works in coordination. For example, the rotating mechanism of rotating sleeve 2 ensures smooth rotation of nut retaining groove 5, thereby tightening or loosening the nut. The connection between rotating sleeve 2 and fixed sleeve 1 ensures the stability and durability of the entire tool. In actual use, the user simply places the nut to be installed into nut retaining groove 5 at the top of rotating sleeve 2 and then easily tightens or loosens the nut by rotating sleeve 2. This design not only simplifies the operation steps but also reduces the difficulty of using the tool, allowing even first-time users to quickly master and operate it proficiently.

[0025] Combine Figure 1 、 Figure 2 and Figure 3As shown, the nut fixing slot 5 is a cylindrical structure with a hexagonal cavity 7 provided on the central axis of the cylinder. Specifically, the cylindrical design of the nut fixing slot 5 not only makes the entire nut fixing slot 5 more visually unified and harmonious, but also provides ample space and flexibility for its internal structure. The cylindrical design ensures that the nut can be naturally aligned and stably placed when placed in the nut fixing slot 5, reducing sliding or shaking caused by shape mismatch. A hexagonal cavity 7 is provided on the central axis of the cylinder, which can perfectly match and secure a standard hexagonal nut. The six sides of the hexagonal cavity 7 tightly fit the six corners of the nut, forming a stable support structure that effectively prevents the nut from loosening or shifting during rotation. The depth and dimensions of the hexagonal cavity 7 are precisely calculated to ensure that it can accommodate nuts of different sizes. This adaptable design makes the handheld adjustable jack nut installation sleeve widely applicable to various occasions requiring nut installation, whether in home maintenance, machinery manufacturing, or construction, where it can play a unique role. In addition, the edges of the hexagonal cavity 7 may also be chamfered to reduce friction and wear when in contact with the nut, while protecting the surface of the nut from scratches. In actual operation, the user only needs to gently place the hexagonal nut into the cylindrical body of the nut fixing groove 5, so that it automatically falls into the hexagonal cavity 7, and then rotate the rotating sleeve 2 to drive the nut to tighten or loosen. The entire process is simple and fast, greatly improving work efficiency and accuracy. At the same time, because the nut is firmly fixed in the cavity, the user does not need to worry about the nut falling off or sliding during rotation, thereby ensuring the safety of the operation.

[0026] Combine Figure 1 、 Figure 2 and Figure 4As shown, the nut fixing groove 5 is a circular tube structure, and a square opening 8 is provided at the top of the circular tube. Specifically, the nut fixing groove 5 is constructed as a circular tube structure, which not only gives it an elegant appearance, but also functionally realizes stable clamping and flexible operation of the nut. The circular tube structure ensures that the nut can slide smoothly to the appropriate position when placed in the nut fixing groove 5, while reducing the resistance or jamming caused by sudden shape changes. A square opening 8 is provided at the top of the circular tube. The size of the square opening 8 has been precisely calculated to be compatible with various specifications of nuts commonly found on the market. When the nut is placed in the circular tube, its top will naturally embed into the square opening 8, forming a stable support point. It not only effectively prevents the nut from shaking or falling off during rotation, but also allows the user to more accurately control the rotation direction and force of the nut. The four corners of the square opening 8 may be rounded to reduce friction and wear when in contact with the nut, while protecting the surface of the nut from being scratched. In addition, the nut fixing groove 5 of the circular tube structure also has good self-cleaning ability. During use, the centrifugal force generated by the nut's rotation can throw tiny impurities or debris out of the tube, keeping the fixing groove clean and unobstructed. In practice, the user can quickly position and secure the nut by aligning it with the square opening 8 and gently pushing it into the tube. Subsequently, the nut can be easily tightened or loosened by rotating the sleeve 2. This not only simplifies the operation process but also improves work efficiency and safety.

[0027] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the rotating sleeve 2 is equipped with two limit rings 9, located at either end of the rotating sleeve 2. These limit rings 9 are used to limit the range of movement of the rotating sleeve 2 within the fixed sleeve 1, ensuring operational stability and safety. Specifically, to control the rotation of the rotating sleeve 2 within the fixed sleeve 1 and prevent it from sliding up and down within the fixed sleeve 1, the rotating sleeve 2 is provided with two limit rings 9. These two limit rings 9 are made of durable materials such as stainless steel or high-strength alloys to ensure long-term reliability and stability. They are installed at either end of the rotating sleeve 2, one near the connection with the hexagonal nut 6 and the other near the mounting point of the connecting block 4. The diameter of the limit rings 9 is slightly larger than the diameter of the internal rotating track of the fixed sleeve 1, but smaller than the diameter of the openings at both ends of the fixed sleeve 1. This design ensures that, while the rotating sleeve 2 can rotate freely within the fixed sleeve 1 during rotation, its axial movement is strictly restricted. In this way, no matter how the user operates, the rotating sleeve 2 will not accidentally slide out of the fixed sleeve 1, thereby ensuring the stability and safety of the operation.

[0028] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, an observation window 10 is provided on the outer wall of the rotating sleeve 2. Specifically, the observation window 10 provided on the outer wall of the rotating sleeve 2 further improves the ease of use and work efficiency of the tool. The observation window 10 serves as a transparent channel between the rotating sleeve 2 and the external environment, allowing the user to directly observe the status of the interior of the sleeve or its connected components without interrupting operation. Through the observation window 10, the user can view the working conditions inside the rotating sleeve 2 in real time, such as the meshing state of the nut and the sleeve, the change in resistance during rotation, etc. This real-time monitoring helps the user to adjust the operating force or angle in time to ensure that the nut can be accurately and smoothly installed in place. For beginners or operators who need training, the observation window 10 also serves as an educational demonstration. By displaying the working process and principle of the rotating sleeve 2, users can better understand the use of the tool and the precautions, thereby improving their operating skills and safety. To achieve the function of the observation window 10, one or more appropriately sized holes are usually opened on the outer wall of the rotating sleeve 2 and sealed with a transparent observation material (such as glass, transparent plastic, etc.). These observation materials need to have good wear resistance, corrosion resistance, and high temperature resistance to ensure that they will not be damaged or affect the observation effect during long-term use. At the same time, to maintain the cleanliness and transparency of the observation window 10, users should pay attention to avoid exposing it to pollutants such as dust and oil during use, and clean and maintain it regularly.

[0029] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the fixed handle 3 is provided with anti-slip texture. Specifically, the anti-slip performance of the fixed handle 3 directly affects the safety and comfort of use. Therefore, anti-slip texture is provided on the surface of the fixed handle 3 to increase the friction between the user's hand and the handle. These anti-slip textures usually adopt an uneven design, such as horizontal or vertical stripes, dot-shaped protrusions or mesh structures. They can not only effectively prevent the hands from sliding in wet or greasy working environments, but also relieve hand fatigue during long-term use. In addition, the material and color of the anti-slip texture may also be coordinated with the overall design of the fixed handle 3 to enhance the aesthetics and overall texture of the product. Some high-end models may even use elastic rubber or silicone materials to make the anti-slip texture part to provide a softer and more comfortable grip.

[0030] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
