Abstract
The utility model relates to a coiling gate theft protection lock, consisting of a lock core mechanism fixedly arranged in the middle of the bottom beam of a coiling gate, two connecting rods with one end arranged on the lock core mechanism and the other end arranged on the bottom beam of the coiling gate, a lock tongue arranged at the end of the connecting rods, and a lock tongue movable seat arranged at the exterior of the lock tongue which can be fixedly connected with the bottom beam of the coiling gate. By adopting the lock tongue movable seat to resist prizing, the utility model reinforces the prizing-proof capability of the coiling gate theft protection lock. After repeated experiments, the prizing-proof effect of the lock is proved to be excellent. The utility model has simple structure and convenient installation, in particular to be suitable for the reconstruction to the existing normal coiling grate theft protection locks.
Description
Technical field
The utility model relates to a kind of burglary-proofing lock for rolling door.
Background technology
Existing burglary-proofing lock for rolling door is installed in the connecting rod that the other end is positioned on the rolling-gate bottom girder lead ring on the lock core mechanism by lock core mechanism, two ends of being fixedly mounted on rolling-gate bottom girder centre to be formed, and the end of connecting rod is a lock pin; This burglary-proofing lock for rolling door, when rolling-gate was closed, the effect of lock core mechanism switch lock was given in the lockpin hole that stays the end reeve slideway of connecting rod, realizes the sealed of rolling-gate.This burglary-proofing lock for rolling door is widely used, but owing to the connecting rod as lock pin is thinner round steel, when lever prized the slideway both sides, round steel was very easily crooked, and caused the damage of burglary-proofing lock for rolling door.
Summary of the invention
Technical problem to be solved in the utility model is to design a kind of burglary-proofing lock for rolling door, to solve the flexible problem of burglary-proofing lock for rolling door lock pin.
The technical scheme of utility model technical solution problem is: it is installed in the connecting rod that the other end is positioned on the rolling-gate bottom girder on the lock core mechanism and forms by being fixedly mounted on rolling-gate bottom girder middle lock core mechanism, two ends, the end of connecting rod is equipped with dead bolt, and the outside of dead bolt is equipped with the dead bolt that can fixedly connected with the rolling-gate bottom girder and is moved seat; The cross section of dead bolt is the square-section.
Owing to adopt technique scheme, utilize dead bolt to move the anti-sled of seat, strengthened the pick-proof ability of burglary-proofing lock for rolling door, through repeatedly experiment, pick-proof is respond well.The utility model is simple in structure, easy for installation, is specially adapted to the transformation of existing common burglary-proofing lock for rolling door.
