Safety protection device of passive intelligent lock based on RFID

Abstract

The invention discloses a safety protection device of a passive intelligent lock based on RFID, and relates to the field of intelligent locks. The safety protection device of the passive intelligent lock based on the RFID comprises a water well mouth, a first welding plate, a second welding plate, a passive intelligent lock assembly and a pre-positioning assembly, the water well mouth is rotationally connected with a well lid, the first welding plate is fixedly connected with a side plate, the side plate is welded to the water well mouth, the second welding plate is welded to the well lid, the passive intelligent lock assembly comprises a lock body, a mounting plate and a clamping lock plate, the pre-positioning assembly comprises a spring and two connecting rods, the connecting rods are fixedly connected with clamping blocks, the two connecting rods are fixedly connected with a handle and a connecting disc respectively, a sliding hole is formed in the handle, and the spring is movably connected into the sliding hole. The safety protection device of the passive intelligent lock based on the RFID has the function that the whole passive intelligent lock assembly can be conveniently installed by pre-positioning the first welding plate and the second welding plate.

Description

technical field [0001] The invention relates to the technical field of intelligent locks, in particular to an RFID-based safety protection device for passive intelligent locks. Background technique [0002] The RFID-based passive smart lock is a common smart lock, which is different from the active smart lock. The active smart lock is equipped with a working power supply in the lock body, and the working power needs to be on standby all the time, otherwise the active smart lock cannot be used. , this will cause the power consumption of the working power supply of the active smart lock to be extremely fast, and the maintenance is extremely troublesome, while the passive smart lock based on RFID is not equipped with a working power supply in the lock body, and the working power supply is set on the smart key. Standby, service life and maintenance difficulty are all better than active smart locks. [0003] RFID-based passive smart locks are widely used. RFID-based passive smar...

[0002] The RFID-based passive smart lock is a common smart lock, which is different from the active smart lock. The active smart lock is equipped with a working power supply in the lock body, and the working power needs to be on standby all the time, otherwise the active smart lock cannot be used. , this will cause the power consumption of the working power supply of the active smart lock to be extremely fast, and the maintenance is extremely troublesome, while the passive smart lock based on RFID is not equipped with a working power supply in the lock body, and the working power supply is set on the smart key. Standby, service life and maintenance difficulty are better than active smart locks

[0003] RFID-based passive smart locks are widely used. RFID-based passive smart locks are often used in the field of hydrogeology. Passive smart locks are used to lock and protect the wellhead of the hydrological logging well and the manhole cover on it. RFID-based passive smart locks are also similar to ordinary mechanical anti-theft locks. The shape of the hydrological logging is generally circular, and it is troublesome to install the RFID-based passive smart lock. The two parts of the RFID-based passive smart lock need to be connected to the wellhead and the well cover respectively. After the two parts are fixed, there is a certain deviation in the position, such as height deviation and angle deviation. These deviations will make it impossible to use the RFID-based passive smart lock normally, which makes the installation of the RFID-based passive smart lock difficult and needs to be improved urgently. Aiming at the deficiencies of the prior art, the present invention discloses a safety protection device for passive intelligent locks based on RFID to solve the above problems
