Abstract
The utility model relates to the technical field of lock. The utility model discloses a simple anti-theft locking device which adopts a cross bolt to lock. The utility model is characterized in that the locking device consists of a lock base plate, a sliding mechanism, a cross bolt and a lock key. One end of the sliding mechanism is hoisted under the lock base plate while the other end is connected with the cross bolt; the cross bolt is fixed with a shift lever; the side of the lock base plate corresponding to the shift lever is provided with a lock hole; the lock key is a fork structure, and the lock key matches the lock hole. When the lock base plate is fixed with the lower side near a well lid and the lock key toggles the shift lever, the shift lever can make the cross bolt inserted into (or left from) the groove of well loop to achieve the aims of locking and opening. The utility model has the advantages of simple structure, convenient and reliable use, and can make the lock base plate and the well lid into integration according to the requirement.
Description
(1) technical field:
The utility model relates to the technical field of locking class.
(2) background technology:
Manhole cover is made up of well lid, walling crib.Existing well lid is unfixing, very easily is stolen and sold.Stolen in order to prevent well lid, some well lids comes antitheftly with chain and cylinder lock are fixing, and this theft-prevention structure neither attractive in appearancely be inconvenient to again use, and metal bracelet very easily gets rusty with being locked under the open-air atmosphere, causes to lock corrosion and can not open, and makes troubles to maintenance.
(3) summary of the invention:
