[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0021] See also Figure 1-6The utility model provides a technical solution: an anti-loosening intelligent fastening nut, comprising a screw 1 and a nut body 2 threadedly connected to the screw 1, a groove 3 is provided on the outer wall of the nut body 2, a mounting block 4 is installed in the inner cavity of the groove 3, a sensor 5 is installed on one side of the mounting block 4, and a fastening mechanism 6 is installed on the inner wall of the nut body 2;

[0022] The fastening mechanism 6 includes a first slide groove 601, a fastening plate 603, a telescopic rod 604, a force block 605 and a spring 606. The first slide groove 601 is opened on the inner wall of the nut body 2, the outer wall of the fastening plate 603 is clamped with the inner cavity of the first slide groove 601, the telescopic rod 604 passes through the ground of the nut body 2 and extends to the inner cavity of the first slide groove 601, the lower end of the force block 605 is fixedly connected to the upper end of the telescopic rod 604, and one side surface of the force block 605 overlaps with one side surface of the fastening plate 603, one end of the spring 606 is fixedly connected to the lower end surface of the force block 605, and the other end of the spring 606 is fixedly connected to the lower end surface of the inner cavity of the first slide groove 601.

[0023] When the nut body 2 moves downward, it contacts the object to be fastened through the telescopic rod 604, so that one end of the telescopic rod 604 drives the force block 605 to move upward. The force block 605 moves upward, and because of the shape of the force block 605 itself, it contacts the fastening plate 603. The fastening plate 603 moves horizontally under the limit of the first slide groove 601, so that the fastening plates 603 are close to each other and contact the screw rod 1, so that the fastening plate 603 and the screw rod 1 are in contact, which increases the friction between the nut body 2 and the screw rod 1, thereby realizing automatic locking of the nut body 2 when connected to the screw rod 1, and increasing the efficiency of the nut body 2 in fastening other objects. When the nut body 2 needs to be disassembled, the elastic force of the spring 606 is used to move the force block 605 downward to prevent the force block 605 from getting stuck, thereby hindering the disassembly of the nut body 2. The nut body 2 is monitored by the sensor 5 installed on the nut body 2, the danger level is determined according to the number of back-offs, and the personnel are alarmed.

[0025] A ball bearing 607 is installed at the bottom of the telescopic rod 604 to prevent the telescopic rod 604 from being damaged due to rotation when it contacts the object to be fastened. The ball bearing 607 reduces the friction between the telescopic rod 604 and the object to be fastened, thereby protecting the telescopic rod 604 and preventing the telescopic rod 604 from breaking during use due to friction.

[0026] Specifically, the fastening mechanism 6 includes a second slide groove 602 , which is disposed in an inner cavity of the first slide groove 601 , and the second slide groove 602 is engaged with an outer wall of the fastening plate 603 .

[0027] The two ends of the fastening plate 603 are limited by the second sliding groove 602, so that the fastening plate 603 moves under the limitation of the second sliding groove 602, thereby increasing the stability of the fastening plate 603 during movement.

[0028] Specifically, the groove 3 is trapezoidal and limits the mounting block 4 .

[0029] The groove 3 can limit the mounting block 4 to prevent the mounting block 4 from being separated from the inner cavity of the groove 3 due to external factors after installation, thereby increasing the stability of the device.

[0030] Specifically, the fastening plate 603 is provided with threads on one side close to the outer wall of the screw rod 1 , and is threadedly connected to the outer wall of the screw rod 1 .

[0031] When the fastening plates 603 are brought close to each other, the threads on the surface of the fastening plates 603 are threadedly connected with the outer wall of the screw rod 1 , and the fastening of the fastening plates 603 to the screw rod 1 is increased through the threads on the surface of the fastening plates 603 and the screw rod 1 .

[0032] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
