Description

Rolling-gate self-locking anti-picking device

The utility model relates to a kind of rolling-gate anti-picking device, particularly a kind of rolling-gate self-locking anti-picking device.

At present, characteristics such as rolling-gate is simple with it, practicality have been widely used in places such as shop, warehouse, but the phenomenon that rolling-gate is pried open happens occasionally, bring very big loss for people's operate as normal, life and property safety, and general rolling gate door lock can not pick-proof and can not self-locking, all need shut by key.

The purpose of this utility model is to provide a kind of more firmly rolling-gate self-locking anti-picking device pick-proof, that can carry out self-locking.

The purpose of this utility model is achieved in that and comprises the lock body 3 that is installed on the rolling door base plate 25, be installed in the dead bolt guiding trestle 5 on the rolling door bottom girder 19, be sleeved on the dead bolt 4 in the dead bolt guiding trestle 5, it is characterized in that: self-locking device 1 is affixed with dead bolt 4 by dead bolt gangbar 13 and dead bolt linkage support 6, the interlock dead bolt 14 affixed with dead bolt gangbar 13 is sleeved in the inner chamber sleeve of lock bolt sleeve 8, be set with dead bolt back-moving spring 7 on the through transport dead bolt 14, be fixed with the self-locking outer casing seat 22 of lock bolt sleeve 8 and the locking pin seat 18 of band pin-and-hole and be packed on the rolling door bottom girder 19, the interlock dead bolt of installing in the lock bolt sleeve 8 14 is installed on the same straight line with the central axis of locking pin seat 18; Bump to be set with in the guide 23 with the affixed self-locking of self-locking outer casing seat 22 and bump pin 15 with the affixed self-locking of self-locking interlock support 9, self-locking is bumped and is set with back-moving spring 10 on the pin 15, with self-locking outer casing seat 22 affixed in locking head key seat 24, be set with self-locking interlock support 9 affixed end head pin 21, end on the head pin 21 being set with back-moving spring 20, be sleeved on the lock pin 11 in the pin key seat 16 and be set with back-moving spring 12.The two ends of rolling-gate bottom girder 19 are separately installed with self-locking device 1 and self-locking device 2, and the structure of self-locking device 1 and self-locking device 2 is identical with the installation connected mode, but installation direction is opposite.

In sum, the utility model has the advantages that: by adopting many lockings control mode of interlock, pick-proof is reliable, simple in structure, practical, easy and simple to handle, flexible, and draws Guan Shike to carry out self-locking at rolling-gate.

The utility model is described in further detail below in conjunction with drawings and Examples.
