Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1:

please refer to fig. 1-3, the utility model relates to a device for detecting bolt is not hard up, including rubber circle 1 and casing 2, casing 2 includes perception face and flank of thread, is provided with micro-gap switch 3 on the perception face, has seted up notch 4 on the flank of thread, and rubber circle 1 is located in notch 4, the inside of casing 2 is provided with battery 5, signal transceiver 6, electronic tags chip 7, LED lamp 9, electronic tags chip 7, micro-gap switch 3 all with signal transceiver 6 electric connection, micro-gap switch 3, electronic tags chip 7, signal transceiver 6 all with battery 5 electric connection. Since the LED lamp 9 is disposed inside the housing 2, the housing 2 needs to be made of a transparent material.

Microswitch 3 is provided with threely altogether, and three microswitch 3 is the annular form and distributes, has seted up the louvre on the casing 2, and notch 4 and rubber circle 1 are fixed through glue pasting.

Example 2:

in this embodiment, the sensing surface 2-1 is the upper surface of the housing, and the screw surface 2-2 is provided with the notch 4, unlike embodiment 1, the LED lamp 9 is disposed on the side surface of the housing 2, so that the housing does not need to be made of a transparent material.
