Technical Field

[0001] The utility model relates to the technical field of bolt loosening detection, in particular to a bolt anti-loosening detection device. Background Art

[0002] Bolt: A mechanical part, a cylindrical threaded fastener that is matched with a nut. A type of fastener consisting of a head and a screw, which needs to be matched with a nut to fasten and connect two parts with through holes. This type of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. During the use of the bolt, the vibration will cause the bolt and nut to loosen, resulting in loose fixation and safety accidents. Therefore, it is necessary to regularly test the tightness of the bolt, and detection equipment is needed.

[0003] When using traditional anti-loosening detection equipment, when testing the tightness of bolts, a torque wrench is often used to turn the bolts, and whether the bolts are loose is detected based on whether the wrench can be turned. When there are many bolts, this detection method is very time-consuming and labor-intensive, and the detection efficiency is low. It cannot meet the needs of detecting the tightness of the bolts well, and this method cannot detect the looseness of the bolts in the first time, which poses a great safety hazard.

[0023] In a preferred embodiment: the inner cavities of the left plate 7 and the right plate 5 are both equipped with adsorption magnets 6, and the adsorption magnets 6 are strong magnets.

[0024] By installing the adsorption magnets 6 in the inner cavities of the right side plate 5 and the left side plate 7, the right side plate 5 and the left side plate 7 can be fixed respectively under the action of the adsorption magnets 6, so that the right side plate 5 and the left side plate 7 can be stably attached to the outer wall of the bottom plate 2, thereby ensuring the stability of the movable plate 10 during use.

[0025] In a preferred embodiment, two ends of the tension spring 9 are respectively connected to the outer wall of the movable plate 10 and the outer wall of the fixed rod 8 , and the static length of the tension spring 9 is less than half of the length of the fixed rod 8 .

[0026] By connecting the two ends of the tension spring 9 to the outer walls of the movable plate 10 and the fixed rod 8 respectively, when the position of the movable plate 10 is adjusted, the tension spring 9 can be lengthened or shortened under the action of the movable plate 10, so that the fixed rod 8 can well pull the movable plate 10 to ensure that the outer wall of the movable plate 10 is tightly attached to the outer edge of the bolt body 3.

[0027] In a preferred embodiment, a slide groove is provided on the outer wall of the right side plate 5 , and the shape and size of the inner wall of the slide groove are equal to the shape and size of the outer wall of the detection plate 11 .

[0028] By means of the slide groove opened in the inner cavity of the right side plate 5, the position of the detection plate 11 can be adjusted on the outer wall of the right side plate 5, so that the pressure switch 16 on the outer wall of the detection plate 11 can be tightly attached to the top of the movable plate 10, ensuring that the movable plate 10 can trigger the pressure switch 16 in the first time when it moves, so that under the action of the pressure switch 16, an early warning of the loosening of the bolt body 3 can be achieved.

[0029] In a preferred embodiment, two ends of the telescopic spring 14 are respectively connected to the outer wall of the pressure plate 15 and the detection plate 11 , and the length of the telescopic spring 14 is smaller than the distance between the outer wall of the detection plate 11 and the outer wall of the right side plate 5 .

[0030] By arranging the pull rod 13, the telescopic spring 14 and the pressure plate 15 on the outer wall of the detection plate 11, the pull rod 13 and the pressure plate 15 are moved under the action of the telescopic spring 14, so that the outer wall of the pressure plate 15 is tightly attached to the outer wall of the bolt body 3, so that the detection plate 11 is fixed to the outer wall of the right side plate 5 under the action of the pressure plate 15 and the limit plate 12.

[0031] In a preferred embodiment, a controller and a signal transmitter are installed in the inner cavity of the left side plate 7 , and the controller and the signal transmitter are electrically connected to the pressure switch 16 respectively.

[0032] Through the controller and signal transmitter installed in the inner cavity of the left side plate 7, when the outer wall of the movable plate 10 is in close contact with the outer wall of the bolt body 3, once the bolt body 3 becomes loose during use, the distance between the bolt body 3 and the nut 4 increases, so that the bolt body 3 can move upward under the action of the movable plate 10 and the tension spring 9. At this time, the movable plate 10 will also move, and the pressure switch 16 will remain stationary and will be triggered under the action of the movable plate 10, thereby sending a signal to the controller, and then under the action of the controller, the signal is transmitted outward through the signal transmitter to remind the user that the bolt body 3 is loose.

[0033] Working principle: When the above-mentioned device is in use, the bolt body 3 is passed through the top plate 1 and the bottom plate 2, and then the nut 4 is installed on the outer wall of the bolt body 3, and the right side plate 5 and the left side plate 7 are adsorbed on the outer wall of the bottom plate 2. At this time, the movable plate 10 will be attached to the outer edge of the bolt body 3 under the action of the fixing rod 8, and the position of the detection plate 11 is adjusted according to the position of the movable plate 10, so that the pressure switch 16 on the outer wall of the detection plate 11 can be tightly attached to the outer wall of the movable plate 10. At this time, the pull rod 13 is pulled, and the telescopic spring 14 can be compressed under the action of the pull rod 13, thereby making the pressure plate 15 leaves from the outer wall of the right side plate 5, and then the position of the detection plate 11 can be adjusted so that the outer wall of the pressure switch 16 can fit with the top of the movable plate 10. When the bolt body 3 becomes loose during use, the position of the nut 4 on the outer wall of the bolt body 3 will be deflected, thereby increasing the distance between the bolt body 3 and the nut 4. The bolt body 3 can move upward under the action of the movable plate 10 and the tension spring 9. At this time, the movable plate 10 will also move upward, thereby triggering the pressure switch 16 and reminding the user under the action of the controller and the signal transmitter.
