It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the scope of protection of the specific request of the utility model. As used in this article, the terms "parallel" and "perpendicular" are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors;
[0025] Combination Figures 1 to 5 As shown, the specific features of the self-locking threaded fastener with an early warning component are described in detail below:
[0026] A self-locking threaded fastener with an early warning component comprises a bolt 1, a fastening nut 2 is threadedly connected to the outer wall of the bolt 1, and an intelligent early warning nut 3 is threadedly connected to the outer wall of the bolt 1. When put into use, the device is first locked by using the bolt 1 in cooperation with the fastening nut 2, and then the intelligent early warning nut 3 is rotated and installed on the bolt 1, and the intelligent early warning nut 3 is fit with the fastening nut 2. A sealing groove 4 is provided at the bottom of the fastening nut 2, and a limiting groove 5 is provided at the bottom of the fastening nut 2. A protective mechanism 6 for protecting the intelligent early warning nut 3 is provided on the bolt 1. By providing the protective mechanism 6, the intelligent early warning nut 3 can be protected to prevent rainwater from directly invading the intelligent early warning nut 3, so that the intelligent early warning nut 3 can maintain a normal working state. A positioning mechanism 7 is provided on the protective mechanism 6. By providing the positioning mechanism 7, the protective mechanism 6 can be made more stable, thereby better protecting the intelligent early warning nut 3.
[0027] In order to protect the intelligent early warning nut 3, the specific protection mechanism 6 includes a base 61, a sleeve 62, a return spring 63, a glass cover 64, and a sealing ring 65; the base 61 is threadedly connected to the outer wall of the bolt 1, the base 61 is rotated to be installed on the bolt 1, and the sealing ring 65 on the top of the sleeve 62 enters the interior of the sealing groove 4, the top of the base 61 is fixedly installed with a glass cover 64, the sleeve 62 is slidably connected to the inner wall of the glass cover 64, the top of the sleeve 62 is fixedly installed with a sealing ring 65, and the sealing ring 65 fits the inner wall of the sealing groove 4. The intelligent early warning nut 3 can be protected by fastening the nut 2 in conjunction with the base 61 and the glass cover 64 to prevent rainwater from directly invading the intelligent early warning nut 3, so that the intelligent early warning nut 3 can maintain a normal working state, one end of the return spring 63 is fixedly installed at the bottom of the sleeve 62, and the other end of the return spring 63 is fixedly installed on the inner wall of the glass cover 64. The elasticity of the return spring 63 can make the sleeve 62 drive the sealing ring 65 to fit tightly against the inner wall of the sealing groove 4.
[0028] In order to further improve the positioning of the glass cover 64, the positioning mechanism 7 includes a slider 71, a limit spring 72, a limit rod 73, and an inclined block 74; the slider 71 is slidably connected to the inner wall of the base 61, one end of the slider 71 extends to the outside of the base 61, the other end of the slider 71 is fixedly installed with a limit spring 72, the end of the limit spring 72 away from the slider 71 is fixedly installed on the inner wall of the base 61, and the top of the slider 71 is fixedly installed with a limit rod 73. Pressing the two sets of sliders 71 makes the slider 71 slide toward the inside of the base 61 and compresses the limit spring 72, while driving The limiting rod 73 is fitted on the outer wall of the glass cover 64, which facilitates the inclined block 74 to enter the interior of the limiting groove 5. The end of the limiting rod 73 away from the slider 71 passes through the base 61 and is fixedly installed with the inclined block 74. The inclined block 74 is clamped on the inner wall of the limiting groove 5. The limiting rod 73 is slidably connected to the penetration of the base 61. The inclined block 74 is used in conjunction with the limiting groove 5, the limiting rod 73, and the slider 71 to fix the distance between the base 61 and the fastening nut 2 to prevent the base 61 and the bolt 1 from loosening, so that the sealing ring 65 can always fit inside the sealing groove 4.
[0029] Working principle: When put into use, first use the bolt 1 to cooperate with the fastening nut 2 to lock the equipment, then rotate the intelligent warning nut 3 to install it on the bolt 1, and make the intelligent warning nut 3 fit with the fastening nut 2, then press the two sets of sliders 71 to make the slider 71 slide toward the inside of the base 61 and compress the limit spring 72, while driving the limit rod 73 to fit the outer wall of the glass cover 64, then rotate the base 61 to install it on the bolt 1, and make the sealing ring 65 at the top of the sleeve 62 enter the inside of the sealing groove 4 and fit tightly inside the sealing groove 4. At this time, the fastening nut 2 cooperates with the base 61 and the glass cover 64 to protect the intelligent warning nut 3, prevent rainwater from directly invading the intelligent warning nut 3, so that the intelligent warning nut 3 can maintain normal working condition When the sealing ring 65 enters the sealing groove 4, the inclined surface block 74 on the top of the limiting rod 73 is also located in the limiting groove 5. At this time, the slider 71 is released again, and the slider 71 can be pushed to the outside of the base 61 by the elasticity of the limiting spring 72. At the same time, the slider 71 will drive the limiting rod 73 to move toward the side away from the glass cover 64. At this time, the limiting rod 73 will drive the inclined surface block 74 on its top to fit into the limiting groove 5. At this time, the inclined surface block 74 will be limited by the limiting groove 5. The inclined surface block 74 cooperates with the limiting groove 5, the limiting rod 73, and the slider 71 to fix the distance between the base 61 and the fastening nut 2, so as to prevent the base 61 and the bolt 1 from loosening, so that the sealing ring 65 can always fit into the sealing groove 4, thereby improving the stability of the glass cover 64.
