[0002] A nut is a mechanical component used to connect and fasten two or more parts. It typically has an internally threaded hole, and the connection is achieved by screwing in a bolt, stud, or other fastener with external threads. Nuts are indispensable components in various industrial applications and are widely used in industries such as machinery, construction, and automobiles.

[0003] According to patent document CN205371245U, a hexagonal nut with a sealing ring is disclosed. The nut end face outside the screw hole has an inner annular groove and an outer annular groove with the same axis. An inner sealing ring and an outer sealing ring are respectively installed in the inner and outer annular grooves. The height of the inner and outer sealing rings is the same, but both are greater than the depth of the bottom of the inner and outer annular grooves. The nut body is made of a magnetic material, and the inner and outer sealing rings are made of rubber soft magnetic strips. The magnetic sides of the inner and outer sealing rings face upwards, and they are adsorbed into the inner and outer annular grooves respectively under magnetic action. This invention can prevent the sealing ring from misaligning and deforming, achieving a good sealing effect, and also prevent the sealing ring from falling off or being lost from the screw.

[0004] After the sealing ring is installed inside the nut, due to long-term use of the nut, the inner side of the sealing ring may be subjected to long-term friction, resulting in severe wear. This can cause the sealing ring to loosen inside the nut and slide on the inner wall of the nut, affecting the sealing function. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a canvas-type sealing ring for nuts, so that the sealing ring will not slip due to wear and affect the sealing of the nut.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a nut canvas sealing ring, comprising a nut, wherein a canvas sealing ring is movably connected to the inner wall of the nut, and a sealing ring fastening mechanism is fixedly connected to the top of the nut;

[0007] The sealing ring fastening mechanism includes a connecting plate, and the top of the connecting plate has a ring array of pressure rod grooves, and pressure rods are slidably connected to the inner walls of the multiple pressure rod grooves.

[0008] Preferably, each of the outer walls of the plurality of pressure rods is fixedly connected to a pressure rod connecting mechanism, and the top of the plurality of pressure rod connecting mechanisms is fixedly connected to a lifting plate.

[0009] Preferably, the bottom of the plurality of pressure rods extends to the inner wall of the nut and is fixedly connected to a pressure plate, the bottom of the pressure plate is movably connected to the top of the canvas sealing ring, and the bottom of the outer wall of the lifting plate is slidably connected to the inner wall of the connecting plate.

[0010] Preferably, the pressure rod connecting mechanism includes a base block, a rotating rod rotatably connected to one side of the top of the base block, a second rotating rod rotatably connected to the side of the top of the base block away from the rotating rod, and a telescopic rod fixedly connected to the top of the second rotating rod.

[0011] Preferably, the inner wall of the rotating rod away from the base is rotatably connected to the outer wall of the telescopic rod, a spring is fitted on the top of the outer wall of the telescopic rod, a third rotating rod is rotatably connected to the side of the rotating rod away from the base, and a fourth rotating rod is rotatably connected to the side of the third rotating rod away from the rotating rod.

[0012] Preferably, a sliding groove rod is fixedly connected to the side of the fourth rotating rod away from the third rotating rod, the inner wall of the sliding groove rod is provided with a sliding groove, a slider is fixedly connected to the top of the telescopic rod, the outer wall of the slider is slidably connected to the inner wall of the sliding groove, and a lifting block is fixedly connected to the side of the sliding groove rod away from the fourth rotating rod, the inner wall of the lifting block is fixedly connected to the top of the outer wall of the pressure rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By incorporating a nut-mounted canvas sealing ring, wear of the sealing ring caused by the rotation and sliding of the nut can be effectively prevented, thereby extending the service life of the sealing ring.

[0015] 2. By setting a sealing ring fastening mechanism, the sealing ring can be more stably kept on the inner wall of the nut when under pressure, avoiding deformation of the sealing ring caused by uneven pressure;

[0016] 3. By combining the pressure rod and the pressure plate, pressure can be applied to the sealing ring when the inner wall of the sealing ring is worn during long-term use, which prevents the sealing ring from loosening inside the nut during use and further improves the sealing effect.

[0017] 4. The addition of a lifting plate makes it easier and faster to replace or adjust the sealing ring, thus improving work efficiency.

[0018] 5. By incorporating a rotating rod and a telescopic rod, the sealing ring achieves automatic adjustment, adapting to nuts of different sizes and enhancing the product's applicability. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1-2 This utility model provides a technical solution: a nut canvas sealing ring, including a nut 1, a canvas sealing ring 3 movably connected to the inner wall of the nut 1, and a sealing ring fastening mechanism 2 fixedly connected to the top of the nut 1.

[0027] Please see Figure 3 , Figure 4 and Figure 5The sealing ring fastening mechanism 2 includes a connecting plate 21. The top of the connecting plate 21 has a ring array of pressure rod grooves 22. Pressure rods 24 are slidably connected to the inner walls of multiple pressure rod grooves 22. Pressure rod connecting mechanisms 25 are fixedly connected to the top of the outer walls of multiple pressure rods 24. A lifting plate 26 is fixedly connected to the top of multiple pressure rod connecting mechanisms 25. The bottom of multiple pressure rods 24 extends to the inner wall of the nut 1 and is fixedly connected to a pressure plate 23. The bottom of the pressure plate 23 is movably connected to the top of the canvas sealing ring 3. The bottom of the outer wall of the lifting plate 26 is slidably connected to the inner wall of the connecting plate 21. The pressure rod connecting mechanism 25 includes a base block 251. A rotating rod 252 is rotatably connected to one side of the top of the base block 251. A second rotating rod 253 is rotatably connected to the side of the top of the base block 251 away from the rotating rod 252. An extension rod 253 is fixedly connected to the top of the second rotating rod 253. The telescopic rod 254 and the rotating rod 252 are rotatably connected to the outer wall of the telescopic rod 254 on the side away from the bottom block 251. A spring 257 is fitted on the top of the outer wall of the telescopic rod 254. A third rotating rod 255 is rotatably connected to the side of the rotating rod 252 away from the bottom block 251. A fourth rotating rod 256 is rotatably connected to the side of the third rotating rod 255 away from the rotating rod 252. A sliding groove rod 258 is fixedly connected to the side of the fourth rotating rod 256 away from the third rotating rod 255. A sliding groove 259 is opened on the inner wall of the sliding groove rod 258. A slider 2510 is fixedly connected to the top of the telescopic rod 254. The outer wall of the slider 2510 is slidably connected to the inner wall of the sliding groove 259. A lifting block 2511 is fixedly connected to the side of the sliding groove rod 258 away from the fourth rotating rod 256. The inner wall of the lifting block 2511 is fixedly connected to the top of the outer wall of the pressure rod 24.

[0028] When the canvas sealing ring 3 needs to be installed, first pull up the lifting plate 26 to move the pressure rod 24 upward. Since the bottom of the pressure rod 24 is fixedly connected to the pressure plate 23, the pressure plate 23 moves upward accordingly, thereby pressing the top of the canvas sealing ring 3 tightly to ensure that the sealing ring is tightly fitted to the inner wall of the nut 1.

[0029] When the lifting plate 26 is lifted, the lifting block 2511 drives the sliding rod 258 to move upward and stretches the telescopic rod 254. Through the second rotating rod 253, rotating rod 252, third rotating rod 255 and fourth rotating rod 256, the lifting plate 26 can be finely adjusted within a certain range so that its bottom can be accurately aligned with the inner wall of the nut 1. When the lifting plate 26 is released and the pressure plate 23 presses on the top of the canvas sealing ring 3, the spring 257 on the telescopic rod 254 provides a certain elastic force to ensure that the pressure rod 24 can maintain a certain pressure when subjected to external force, preventing the canvas sealing ring 3 from loosening during use.

[0030] Finally, after installation is completed and the lifting plate 26 is released, the pressure rod 24 will automatically descend due to the elastic force of the spring 257, and the pressure plate 23 will descend accordingly. The canvas sealing ring 3 is firmly fixed to the inner wall of the nut 1, ensuring the stability and reliability of the sealing ring.

[0031] Working principle: When the canvas sealing ring 3 needs to be installed, first pull up the lifting plate 26 to move the pressure rod 24 upward. Since the bottom of the pressure rod 24 is fixedly connected to the pressure plate 23, the pressure plate 23 moves upward accordingly, thereby pressing the top of the canvas sealing ring 3 tightly, ensuring that the sealing ring is tightly fitted to the inner wall of the nut 1. When the lifting plate 26 is lifted, the lifting block 2511 drives the sliding rod 258 to move upward and drives the telescopic rod 254 to stretch. Through the second rotating rod 253, rotating rod 252, third rotating rod 255 and fourth rotating rod 256, the lifting plate 26 can be finely adjusted within a certain range so that its bottom can be accurately aligned with the inner wall of the nut 1. When the lifting plate 26 is released and the pressure plate 23 is pressed on the top of the canvas sealing ring 3, the spring 257 on the telescopic rod 254 provides a certain elastic force, ensuring that the pressure rod 24 can maintain a certain pressure when subjected to external force, preventing the canvas sealing ring 3 from loosening during use.

[0032] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
