Embodiment Construction

[0032] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] Such as figure 1 with figure 2 As shown, the vibration measurement sensor of the present invention includes a metal housing 1, which plays a role of shielding and protection. The internal structure of the vibration measurement sensor of the present invention is as figure 2 shown. The vibration measurement sensor includes a sensor upper cover 4 , a plastic base 8 , a coil frame 6 , an upper cover spring 10 and a base spring 7 , and a permanent magnet 11 is connected between the sensor upper cover 4 and the plastic base 8 . The coil bobbin 6 is sleeved outside the permanent magnet 11 , and there is a gap between the coil bobbin 6 and the permanent magnet 11 .

[0034] A double-coil winding 5 is wound on the outer surface of the bobbin 6, and the double-coil winding 5 is composed of two upper and lower coils connected ...

Abstract

A transducer of measuring vibration is prepared as connecting permanent magnet with top cover and base; winding coil on coil skeleton being sheathed outside of permanent magnet; connecting coil skeleton top end with top cover through top cover spring and its bottom end with base through base spring; forming top cover, base, permanent magnet, coil skeleton, top cover spring and base spring to be an integral structure.

Description

technical field [0001] The invention relates to the technical field of security protection, in particular to a vibration measurement sensor sensitive to vibration shock signals for intrusion and anti-theft alarm. Background technique [0002] In recent years, with the development of my country's economy, people's quality of life has been continuously improved, and the accumulation of social wealth has reached a considerable level. The theft of illegal and criminal acts against state property is on the rise, and cases of theft of banks, treasuries, museums, ancient tombs, and gun and ammunition depots occur from time to time. Once such a case is successfully committed, it will cause huge irreparable losses. But criminals often mostly adopt from the ground to dig holes close to underground vaults to the theft of banks, vaults, etc., or punch holes in the wall to steal bank safes, which are difficult for monitors to find. Therefore, the more effective anti-theft means at pres...
