In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize applications of other processes and/or uses of other materials.
Referring to fig. 1 to 5, in the power system of the anti-loose stress device according to the embodiment of the present invention, a bolt 1 penetrates through a first nut 2 and an anti-loose sensor 3, and is fixedly and tightly connected to a substrate 4 and a liner 5. The substrate 4 is a part of the intelligent conveyor belt system, and the substrate 4 at the blanking position of the conveyor belt is subjected to more blanking impacts, so that the impact of the blanking is buffered by using the lining plate 5 to protect the substrate 4.
Generally, the base plate 4 and the lining plate 5 can be fixedly connected by using one nut, in the invention, two nuts or bolt heads are used for fixing, the second nut 6 or bolt head is used for fixing the connecting bolt 1, and the base plate 4 and the lining plate 5 are positioned between the first nut 2 and the second nut 6 or bolt head, thereby further enhancing the stability of the arrangement of the bolt 1.
The anti-loosening sensor 3 is positioned between the first nut 2 and the lining plate and is electrically connected to the alarm unit. The alarm unit may be a display screen, an alarm, etc., and is not limited herein.
In the present embodiment, the lock sensor 3 is a pressure sensor.
The connection position of the lead and the lock sensor 3 is located on the side of the lock sensor 3. So, the wiring is convenient, and when a plurality of bolts 1 were fixed on a face of base plate 4 in addition, a plurality of lock sensor 3's wire was conveniently arranged, avoided the chaotic mutual interference of wiring, influenced the detection accuracy.
The orthographic projection of the first nut 2 on the pressure sensor is located on the pressure sensor. That is, the outer diameter of the first nut 2 is smaller than the outer diameter of the pressure sensor, so that the pressure exerted by the first nut 2 on the pressure sensor can be detected more accurately by the pressure sensor, and the pressure change can be detected more promptly by the pressure sensor. In addition, the structure is also beneficial to enhancing the stability of the integral structure of the power system of the anti-loosening stress element.
