Description

Technical Field

[0001] This utility model relates to the field of universal coupling technology, specifically a universal coupling protection device. Background Technology

[0002] A universal coupling is a mechanical transmission element used to connect different shafts. It can reliably transmit torque and motion even when there are angular, axial, or radial deviations between the two shafts. Through its unique structural design, it allows the two shafts to move relative to each other in different directions while maintaining stable power transmission.

[0003] Authorization announcement number CN222363288U discloses a universal joint protection device and a universal joint. This patented technology can support the intermediate shaft, maintain its balance, and buffer and balance its height and tilt angle. It can prevent the intermediate shaft from swinging with the rotation of the connecting fork when the cross shaft breaks during operation, thus preventing equipment damage or even harm to operators. However, in humid or moisture-rich environments, the metal parts of the universal joint are prone to rust due to moisture intrusion, leading to accelerated wear, cracks, or even breakage. Moisture entering the universal joint causes poor lubrication, increases frictional resistance, and reduces transmission efficiency. The lack of waterproof protection accelerates the aging and damage of internal components, significantly shortening its service life. Because the components are easily damaged, more frequent repairs or replacements are required, increasing maintenance costs and potentially leading to increased equipment downtime. Therefore, a universal joint protection device is needed to address these problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0027] A universal coupling protection device includes a main body 1, and a protective component 2, a waterproof component 3 and a connecting component 4 are fixedly connected to the top of the main body 1.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the main body 1 includes a base frame 101, with a mounting plate 102 fixedly connected to the side of the base frame 101. The protective component 2 includes a polypropylene protective cover 201, with a shaft 202 disposed inside the polypropylene protective cover 201. A shaft rod 204 is fixedly connected to the side of the shaft 202, and a drive connecting rod 203 is fixedly connected to the side of the shaft 202. The waterproof component 3 includes a connecting cylinder rod 301, with a transparent waterproof cover 302 fixedly connected to the side of the connecting cylinder rod 301. A sealing gasket 303 is fixedly connected inside the transparent waterproof cover 302. The polypropylene protective cover 201 protects the shaft 202, giving it good corrosion resistance to most chemicals and enabling it to resist the erosion of water, inorganic salts, acids, alkalis, etc. The polypropylene protective cover 201 can maintain stable performance at high temperatures, making it suitable for protective scenarios that require high-temperature environments. Polypropylene material has low cost, good processing performance, and is easy to mold and manufacture.

[0029] The shaft 204 passes through the sealing gasket 303 and extends into the interior of the transparent waterproof cover 302. A first bracket 205 is fixedly connected to the top of the base frame 101. A screw 206 is installed inside the polypropylene protective cover 201 and extends into the interior of the first bracket 205. A second bracket 307 is fixedly connected to the top of the base frame 101. A connecting plate 305 is installed on the top of the second bracket 307. The connecting plate 305 is located on the side of the connecting cylinder 301. A second thread is provided at the connection between the connecting cylinder 301 and the connecting plate 305. The bottom of the connecting plate 305 is provided with a third threaded rod 306, which extends into the interior of the second bracket 307. The transparent waterproof cover 302 and the sealing gasket 303 can effectively prevent moisture from entering the shaft 204, reduce corrosion and rust caused by the humid environment, and thus significantly extend the service life of the shaft 204 and related components. The waterproof measures can prevent water from entering the bearing or other critical components, avoid lubricant deterioration or failure caused by moisture, and thus ensure the stability and reliability of the equipment during long-term operation.

[0030] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, the connecting component 4 includes a third bracket 401, of which two third brackets 401 are provided. A top frame 402 is fixedly connected to the top of the third bracket 401, and a base 403 is fixedly connected to the top of the top frame 402.

A limit plate 406 is provided on the side of the shaft cylinder 405. Multiple brackets are designed to fix each part and are equipped with threaded fasteners to ensure stability while facilitating disassembly and preventing parts from falling off during operation and causing injury to equipment or personnel.

[0031] The working process of this utility model is as follows: When the universal coupling protective device designed in this scheme is in operation, the polypropylene protective cover 201 makes the shaft 202 highly resistant to corrosion by most chemicals, while the transparent waterproof cover 302 and the sealing gasket 303 have good waterproof and dustproof performance, which can effectively prevent moisture, dust and other impurities from entering the universal coupling. This ensures that the universal coupling can effectively prevent moisture from entering in humid or wet environments, reducing the risk of corrosion and thus extending the service life of the coupling. Since the waterproof design can effectively prevent corrosion and lubricant deterioration, the maintenance frequency and repair cost of the universal coupling will be significantly reduced. This not only saves maintenance time, but also reduces economic losses caused by equipment downtime.
