[0002] A bushing is a cylindrical mechanical part that fits on a rotating shaft. It protects the shaft, reduces friction between the shaft and other components, and provides positioning. The bushing is usually made of wear-resistant materials, such as copper alloy, aluminum alloy, and engineering plastics. Its shape is generally cylindrical, with an inner diameter that matches the diameter of the shaft, and an outer diameter that depends on specific usage requirements. The bushing can be used alone or in combination with other parts, such as bearings and seals. In a mechanical transmission system, the shaft is a key component for transmitting power and motion. However, during operation, the shaft will rub against and wear other components, which will not only reduce the service life of the shaft, but also affect the performance and reliability of the entire transmission system. In order to solve this problem, people invented bushings. Early bushings were mainly made of metal materials, such as copper and iron. These metal bushings have high strength and durability. Although it is resistant to abrasion, it also has some disadvantages, such as heavy weight, high cost, and difficulty in processing. With the emergence of new materials such as engineering plastics, plastic bushings have gradually been widely used. Plastic bushings have the advantages of light weight, low cost, and easy processing. At the same time, they also have good wear resistance, self-lubrication and corrosion resistance. With the continuous advancement of science and technology, the technology of bushings is also constantly innovating and developing. For example, some new bushings are made of composite materials with higher strength, wear resistance and corrosion resistance. Some bushings use special surface treatment technologies, such as coating and plating, which can further improve the performance and service life of the bushings. Some bushings are also integrated with functional components such as sensors, which can realize shaft status monitoring and fault diagnosis. At present, there are still many inconveniences in the installation of bushings. Therefore, there is a special need for a bushing that is easy to install.

[0003] However, there are still problems with the installation of existing shaft sleeves. For some shaft sleeves that are installed by press-fitting, special pressing tools and equipment are required, which not only increases the cost of installation, but also makes installation very difficult in some occasions where there is no press-fitting equipment. In addition, the press-fitting installation also needs to consider the material properties of the shaft sleeve and the connecting parts to avoid deformation or damage of the parts due to excessive press-fitting force. Due to the many factors to consider, the installation efficiency is reduced. Utility Model Content

One end surface of the sleeve 1 is fixedly connected to the sleeve seat 301, the bottom surface of the sleeve seat 301 is connected to the mounting frame 302, and the two side surfaces of the mounting frame 302 are fixedly connected to the fixing plate 303. The surfaces of the fixing plate 303 and the sleeve seat 301 are both provided with fixing holes 304. The outer surface of the fixing hole 304 is fixedly connected to the first telescopic spring. The first expansion spring 305 is fixedly connected to the first stopper 306 on the outer end surface of the first expansion spring 305, and the inner surface of the first stopper 306 is fixedly connected to the fixing rod 307. The bottom side surface of the mounting frame 302 is fixedly connected to the connecting plate 308, and the bottom surface of the connecting plate 308 is connected to the mounting plate 309. The upper surface of the connecting plate 308 is provided with a stop groove 310. The surfaces of the connecting plate 308 and the mounting plate 309 are both provided with a threaded groove 311. The inner wall surface of the threaded groove 311 is threadedly connected to a threaded rod 312. The upper surface of the threaded rod 312 is fixedly connected to a connecting rod 313. The two side surfaces of the connecting rod 313 are provided with a limiting groove 314. The outer wall surface of the connecting rod 313 is slidably connected to a stop ratchet 315. The inner surface of the stop ratchet 315 is fixedly connected to the limit block 316, and the top surface of the connecting rod 313 is fixedly connected to the second stop block 317. Through the setting of the mounting mechanism 3, when the shaft sleeve 1 needs to be installed, the shaft sleeve 1 is first initially positioned near the installation position using the mounting bracket 302. The fixing holes 304 on the fixing plates 303 on both sides of the mounting bracket 302 play a role in fixing and positioning. When further fixing is required, the first telescopic spring 305 is in a compressed state, pushing the first stop block 306 to move inward, so that the fixing rod 307 is inserted into the fixing hole of the corresponding installation part to achieve preliminary fixation. For the connection between the connecting plate 308 and the mounting plate 309, they are fixed by the threaded groove 311 and the threaded rod 312. The threaded rod 312 is screwed into the threaded groove 311, so that the connecting plate 308 and the mounting plate 309 are tightly connected. During this process, the limit groove 314 on the connecting rod 313 cooperates with the limit block 316 on the inner side of the stop ratchet 315 to prevent the threaded rod 312 from loosening accidentally.

This installation mechanism 3 avoids the disadvantages of traditional press-in installation, does not require special pressing tools and equipment, reduces installation costs, and can be installed more conveniently in various occasions without being restricted by pressing equipment. At the same time, there is no need to consider too much about the influence of the material properties of the sleeve and the connector on the pressing force, thereby improving installation efficiency.

[0023] Furthermore, the outer surface of the sleeve 1 is coated with an anti-corrosion agent, and multiple groups of anti-corrosion layers 2 are provided inside the sleeve 1. By providing the anti-corrosion layer 2, the outer surface of the sleeve 1 is coated with the anti-corrosion agent, which can effectively prevent the sleeve from being corroded in the external environment and extend the service life of the sleeve 1. In various harsh working environments, it can maintain good performance. The multiple groups of anti-corrosion layers 2 provided inside the sleeve 1 further enhance the anti-corrosion ability of the sleeve 1, protect the sleeve 1 from medium corrosion from the inside, and ensure that the sleeve 1 maintains stable performance during long-term use.

[0024] Furthermore, the first stop block 306 cooperates with the fixing rod 307 through the first telescopic spring 305 to form a telescopic structure. The outer wall size of the fixing rod 307 is consistent with the inner wall size of the fixing hole 304. Through the setting of the fixing hole 304 and the fixing rod 307, during the installation process, the fixing rod 307 can be flexibly inserted into the fixing hole 304 under the action of the first telescopic spring 305 to achieve rapid fixation. At the same time, the outer wall size of the fixing rod 307 is consistent with the inner wall size of the fixing hole 304, which ensures the tightness of the fixation and prevents the sleeve from loosening during use.

[0025] Furthermore, the inner wall size of the threaded groove 311 is consistent with the outer wall size of the threaded rod 312, and the threaded rod 312 threadedly connects the connecting plate 308 to the mounting plate 309 through the threaded groove 311. Through the arrangement of the threaded groove 311 and the threaded rod 312, the threaded rod 312 can be tightly matched with the threaded groove 311, and the connecting plate 308 is threadedly connected to the mounting plate 309 through the threaded rod 312, ensuring the firmness and stability of the connection. During the operation of the equipment, this connection method can withstand greater force and vibration, and is not easy to loosen or fall off, thereby ensuring the normal operation of the equipment. At the same time, the threaded connection is convenient for installation and disassembly, and is convenient for maintenance and replacement of parts.

[0026] Furthermore, the position of the stopping ratchet 315 corresponds to the position of the stopping groove 310, and the outer wall size of the stopping ratchet 315 is consistent with the inner wall size of the stopping groove 310. Through the setting of the stopping groove 310 and the stopping ratchet 315, under certain circumstances, the stopping ratchet 315 can be stuck in the stopping groove 310 to play a stopping role. When the threaded rod 312 is screwed into the threaded groove 311, the cooperation between the stopping ratchet 315 and the stopping groove 310 can provide a reliable locking function. This stopping mechanism increases the safety and reliability of the equipment and prevents accidents caused by accidental movement of components.

[0027] Furthermore, the position of the limit block 316 corresponds to the position of the limit slot 314, and the outer wall size of the limit block 316 is consistent with the inner wall size of the limit slot 314. Through the setting of the limit slot 314 and the limit block 316, the cooperation of the limit block 316 and the limit slot 314 can limit the movement range of the component and ensure that it moves within the specified range. During the operation of the equipment, this limiting function can prevent the component from excessive movement or deviating from the correct position, thereby ensuring the accuracy and stability of the equipment. At the same time, the cooperation between the limit block 316 and the limit slot 314 can also play a guiding role, making the component more stable and smooth during movement.

[0028] Furthermore, the position of the slider 6 corresponds to the position of the chute 4, and the outer wall size of the slider 6 matches the inner wall size of the chute 4. Through the setting of the chute 4 and the slider 6, the cooperation of the slider 6 and the chute 4 provides guidance and support for the movement of the device. The slider 6 can slide smoothly in the chute 4, reducing the friction and resistance during the movement, making the movement of the device easier and more efficient.

[0029] Working principle: First, the outer wall surface of the sleeve 1 is coated with an anti-corrosion agent, and multiple groups of anti-corrosion layers 2 are arranged inside. This allows the sleeve to effectively prevent external and internal corrosion in various harsh working environments, extend its service life and maintain good performance. During the installation process, the sleeve 1 is initially positioned near the installation position using the mounting frame 302. The fixing holes 304 on the fixing plates 303 on both sides of the mounting frame 302 play a role in fixing and positioning. At this time, the first telescopic spring 305 is in a compressed state, pushing the first stopper 306 to move inward, so that the fixing rod 307 Insert it into the fixing hole of the corresponding installation part to achieve preliminary fixation. This fixing method is fast and firm and can adapt to different installation environments. For the connection between the connecting plate 308 and the mounting plate 309, it is fixed through the threaded groove 311 and the threaded rod 312. The threaded rod 312 is screwed into the threaded groove 311, so that the connecting plate 308 and the mounting plate 309 are tightly connected. In this process, the limit groove 314 on the connecting rod 313 cooperates with the limit block 316 on the inner side of the stop ratchet 315 to prevent the threaded rod 312 from accidentally loosening. When the threaded rod 312 is continuously screwed in, , the stop ratchet 315 slides on the connecting rod 313 until it contacts the second stop block 317 and stops. This installation mechanism avoids the disadvantages of traditional press-in installation, does not require special press-fitting tools and equipment, reduces installation costs, and can be installed more conveniently in various occasions without being restricted by press-fitting equipment. At the same time, there is no need to consider too much about the influence of the material properties of the sleeve and the connector on the press-fitting force, thereby improving installation efficiency. Inside the sleeve 1, the sliders 6 at both ends of the bearing 5 cooperate with the slide groove 4 on the inner wall surface of the sleeve 1. The slider 6 can slide smoothly in the slide groove 4, providing guidance and support for the movement of the bearing 5, reducing friction and resistance during movement, making the movement of the equipment easier and more efficient. At the same time, this cooperation method can also ensure the movement accuracy and stability of the equipment, preventing the bearing 5 from deflecting or shaking during movement. In summary, the sleeve that is easy to install has good anti-corrosion performance through the synergistic effect of multiple structures, and can provide stable and reliable performance during installation and use, adapting to various working environments and installation requirements, thus completing the use process of a sleeve that is easy to install.
