[0001] This utility model relates to the field of nut technology, specifically an integrated anti-loosening nut. Background Technology

[0002] In the field of mechanical connections, nuts are key fasteners, and their reliability directly affects the safety and stability of mechanical equipment. Nuts are screws that are tightened together with bolts or screws to fasten the parts.

[0003] Existing one-piece lock nuts typically do not consider improving the sealing of the nut connection, which makes it easy for dust and other impurities to enter the gap between the nut and the screw or bolt connection, making subsequent disassembly and assembly of the nut more troublesome. In addition, existing one-piece lock nuts require the use of tools such as wrenches to turn them, and it is often difficult to disassemble and assemble the nut when wrenches and other tools are unavailable. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] The following is in conjunction with the appendix Figure 1-4 The technical solution of this utility model will be further explained below:

[0025] Example 1: As Figures 1-3As shown, the integrated anti-loosening nut includes a nut body 1, a spacer ring 2 on the outer side of the nut body 1, an edge above the spacer ring 2, a face ring groove 8 on the top of the nut body 1, and a sealing component inside the face ring groove 8 to maintain the sealing of the nut connection; the sealing component includes a circular groove 9, a limiting slide groove 10, a first spring 11, a sliding strip 12, a movable column 13, and a rubber washer 14; the inner bottom wall of the face ring groove 8 is uniformly provided with circular grooves. 9. The inner wall of the circular groove 9 is symmetrically provided with limiting grooves 10. A sliding strip 12 is installed in the circular groove 9 through the limiting groove 10, and the two ends of the sliding strip 12 are slidably connected to the limiting groove 10. A first spring 11 is installed in the inner bottom wall of the circular groove 9, and the first spring 11 is connected to the bottom of the sliding strip 12. A movable column 13 is installed in the top of the sliding strip 12, and a rubber washer 14 is connected in the top of the movable column 13. The inner arc surface and the outer arc surface of the rubber washer 14 are in contact with the arc surface of the face ring groove 8. The nut body 1 provides an installation position for the spacer ring 2. The spacer ring 2 separates the corners and bottom of the nut body 1, preventing damage to the parts below the nut body 1 when the wrench is stuck at the corners of the nut. The corners above the spacer ring 2 of the nut body 1 can match the wrench, allowing the wrench to turn the nut. The nut body 1 provides an opening position for the face ring groove 8, which provides an installation position for the sealing component. The face ring groove 8 provides an opening position for the circular groove 9, which provides an opening position and an installation position for the limiting slide groove 10 and the first spring 11, respectively. The limiting slide groove 10 provides sliding space for the sliding bar 12 and limits the movement of the sliding bar 12. The first spring 11 connects the sliding bar 12 to the bottom wall of the circular groove 9. The sliding bar 12 provides an installation position for the movable column 13, which provides an installation position for the rubber washer 14. The rubber washer 14 contacts the side arc wall of the face ring groove 8, ensuring that the moving rubber washer 14 remains in contact with the surface. This system ensures a sealed connection at the nut joint. After installation, the rubber washer 14 on the nut contacts the surface of the object being fixed, compressing the first spring 11. The restoring force of the first spring 11 is transmitted to the rubber washer 14 via the sliding bar 12 and the movable column 13, causing the rubber washer 14 to press tightly against the contact surface of the object being fixed, thus ensuring the seal at the nut joint, preventing dust from entering, and improving the tightness of the device. If the nut joint is loosened by external force, the compressed first spring 11 releases a certain length under the action of elastic restoring force, but remains compressed. The released force causes the sliding bar 12 to slide, moving the movable column 13 and the rubber washer 14 toward the surface of the object being fixed, thus ensuring the rubber washer 14 is tightly against the surface of the object being fixed, maintaining the seal at the nut joint even if the nut is slightly loose.

[0026] Example 2: Figure 1 and Figure 2As shown, the nut body 1 has symmetrically arranged receiving cavities 3 inside, and a screw 4 is installed through the outer surface of the nut body 1. One end of the screw 4 is located inside the receiving cavity 3, and one end of the screw 4 is connected to a limiting plate 5, which is located inside the receiving cavity 3. The other end of the screw 4 is connected to a round block 6, which is located outside the nut body 1. An anti-corrosion layer 7 is provided on the outer side of the nut body 1. The nut body 1 provides space and installation position for the cavity 3 and screw 4 respectively. The cavity 3 provides movable space for the screw 4, and the screw 4 provides installation position for the limiting disc 5 and the round block 6. The limiting disc 5 prevents the screw 4 from falling out of the nut body 1, and the round block 6 prevents the screw 4 from being excessively rotated into the cavity 3. The anti-corrosion layer 7 on the outside of the nut body 1 can improve the service life of this integrated anti-loosening nut. When there are no tools such as wrenches to install and remove the nut, the worker can rotate the screw 4 to extend it outward a certain distance. At this time, the worker can apply a lateral rotation force on the nut by holding the screw 4. The cooperation between the screw 4 and the cavity 3 allows the worker to rotate and install the nut without tools by using the screw 4, which is beneficial to improving the practicality of the nut. After rotating the nut by the screw 4, rotating the screw 4 will cause the screw 4 to screw into the cavity 3, reducing the space occupied by the screw 4 exposed to the outside.

[0027] Example 3: Figure 1 and Figure 4As shown, a bottom ring 15 is installed at the bottom of the nut body 1, and the bottom ring 15 is aligned with the center line of the nut body 1. A pull rod 16 is installed through the outer surface of the bottom ring 15. One end of the pull rod 16 is connected to an arc-shaped stop block 17, which is located inside the bottom ring 15. A pull plate 19 is installed at the other end of the pull rod 16. Second springs 18 are evenly distributed on the outer surface of the bottom ring 15, and the second springs 18 are located outside the pull rod 16. One end of the second spring 18 is connected to the pull plate 19. An anti-slip pad 20 is installed on the inner arc surface of the arc-shaped stop block 17. The nut body 1 provides an installation position for the bottom ring 15, which in turn provides an installation position for the pull rod 16. The pull rod 16 provides an installation position for the arc-shaped abutment 17 and the pull plate 19. The bottom ring 15 provides an installation position for the second spring 18, which connects the outer surfaces of the pull plate 19 and the bottom ring 15. The arc-shaped abutment 17 provides an installation position for the anti-slip pad 20, which increases the friction between the arc-shaped abutment 17 and the threaded portion of the bolt, thereby improving the stability of the arc-shaped abutment 17 when pressing against the threaded portion of the bolt. When this nut and bolt are connected, By pulling the pull plate 19 outward, the pull rod 16 is moved, and the second spring 18 is stretched, so that the arc-shaped stop 17 does not block the connection between the bolt thread and the nut. After the nut and bolt are fastened together, the pull plate 19 is released, and the second spring 18 returns to a certain length but is still in a stretched state. The elastic restoring force released by the second spring 18 after restoring part of its length causes the arc-shaped stop 17 to move closer to the bolt thread. The second spring 18 is still stretched, so its elastic restoring force can make the arc-shaped stop 17 press against the bolt thread, thereby preventing the nut from loosening.

[0028] Working principle: Before using the lock nut, check whether there are any problems that may affect its use. First, determine the installation and removal method of the nut based on whether there are tools such as a wrench. If there are tools such as a wrench, make the wrench engage with the outer edge of the nut body 1 to apply force to install or remove the nut. If there are no tools such as a wrench, the worker can rotate the screw 4 to extend it outward a certain distance. At this time, the worker can hold the screw 4 to apply a lateral force to rotate the nut, thereby rotating the nut for installation and removal. When the screw 4 is not needed to install or remove the nut, rotate the screw 4 to screw it into the cavity 3 to reduce the space occupied by the screw 4 exposed on the outside.

[0029] After the nut is installed, the rubber washer 14 on the nut contacts one side of the object being fixed, the first spring 11 is compressed, and the spring restoring force of the first spring 11 is transmitted to the rubber washer 14 through the sliding bar 12 and the movable column 13, so that the rubber washer 14 presses tightly against the contact surface of the object being fixed, thereby ensuring the sealing of the nut connection, preventing dust from entering the connection, and improving the tightness of the device.

[0030] After the nut and bolt are used to fasten the object, the pull plate 19 is loosened. The second spring 18 returns to a certain length but is still in a stretched state. The elastic restoring force released by the second spring 18 after restoring part of its length causes the arc-shaped abutment 17 to move closer to the threaded part of the bolt. The second spring 18 is still stretched, so its elastic restoring force can make the arc-shaped abutment 17 press against the threaded part of the bolt. After the nut is tightened, it can apply an additional clamping force to the threaded connection, thereby effectively preventing the nut from loosening due to vibration.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
