The lock core in the upper position of the inner cavity of the lock body is connected with a slid slot connecting rod mechanism. The connecting rod mechanism drives the lock tongue in the lower end of the lock body to shrink or expand to finish the match or disengagement with the locking box. The utility model has the advantages of simple structure, convenient installation, high reliability, etc.
Description
The utility model relates to the theftproof lock that uses on a kind of rolling-gate or the sliding door.
At present, when the door of sliding door or rolling-gate and so on is closed, most padlocks that use, the shackle that is about to be provided with on door and the doorframe is aimed at the back and with padlock both is connected firmly, and closes antitheft purpose to reach, in fact, adopt this type of padlock, because padlock body is open outdoors, stealer only need use the rod member instrument commonly used of screwdriver and so on just lock can be pried open, and is very dangerous.
The purpose of this utility model is to provide the theftproof lock of installing and using on a kind of rolling-gate.
For achieving the above object, the technical solution adopted in the utility model is: burglary-proofing lock for rolling door, it comprises lock body, lock core, dead bolt are arranged on the lock body, keeper is used for cooperating door and doorframe pinning with dead bolt, have on lock body, the keeper and door and the installing hole that connects of doorframe, its special feature is: the lock core at the upper position place of lock body inner chamber links to each other with the chute linkage, and this linkage drives the set dead bolt contraction in lock body lower end or stretching, extension and cooperates with keeper or break away to finish.
In the utility model, lock body, keeper fellow disciple and doorframe are respectively installed and are connected firmly, the position that contains keyhole on the lock core is revealed on the body, is rotated by key operated lock core, drives the chute linkage, this linkage drives the dead bolt that is connected and moves and enter in the lock body, this moment, dead bolt separated with keeper, and door is opened with doorframe, when the lock body hypomere inserts in the keeper together with dead bolt, dead bolt stretches and when exposing lock body, dead bolt cooperates with keeper and door and frame are locked firmly.
Fig. 1, the 2nd, assembly structure schematic diagram of the present utility model;
Fig. 3 is a schematic appearance of the present utility model;
Fig. 4 is the structural representation of keeper;
Fig. 5 is an A--A sectional view among Fig. 4.
The utility model is described in further detail below in conjunction with drawings and Examples.
