Exchangeable rope type sign
The invention provides an exchangeable rope type sign comprising a housing, a conductive antitheft protection rope and an antitheft alarm circuit. The antitheft protection rope forms a part of the antitheft alarm circuit to work as an alarm trigger switch for the antitheft circuit. The exchangeable rope type sign is characterized in that the antitheft protection rope can be detachably connected to a sign and protected by a protection device from being illegally detached. By the use of the exchangeable rope type sign, the antitheft rope can be conveniently detached, rope sign use cost can be reduced and the antitheft protection rope can be prevented from being illegally detached; further the antitheft protection rope can be prevented from being unconsciously detached, so use safety and reliability can be achieved and wrong alarm can be prevented; the detachment scheme can be combined with a telescopic adjusting scheme of the antitheft protection rope, so use convenience is improved, rope type sign functions are expanded; and rope string and insertion operation of the antitheft protection rope can be realized.
