Description
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.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a self-locking device sectional structure schematic diagram;
Fig. 3 is the backsight sectional view of Fig. 2;
Fig. 4 is that the A-A of Fig. 3 is to the cross-sectional structure schematic diagram.
By Fig. 1-4 as can be known, the utility model 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 characterised 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, this inner chamber sleeve one end is provided with backing pin hole circle, so that back-moving spring 7 is installed, the internal chamber wall of the other end is provided with the backing pin circle of projection, the collar that interlock also is correspondingly provided with projection on the dead bolt 14 with stop interlock dead bolt 14 not the elastic force effect of reason back-moving spring 7 stretch out outside the sleeve down.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.Pin key seat 16 is fixedly mounted on the appropriate location, ground by set bolt 17, so that rolling-gate is when closing, pin key seat 16 just in time is enclosed between lock bolt sleeve 8 and locking pin seat 18 install, and make the interlock dead bolts 14 installed in the lock bolt sleeve 8, be sleeved on the lock pin 11 in the pin key seat 16, the central axis of locking pin seat 18 is installed on the same straight line; Inner chamber sleeve one end of pin key seat 16 is provided with backing pin hole circle, so that back-moving spring 12 is installed, the internal chamber wall of the other end is provided with the backing pin circle of projection, the collar that also is correspondingly provided with projection on the lock pin 11 with stop lock pin 11 not reason back-moving spring 12 the elastic force effect down and stretch out outside the sleeve of pin key seat 16.Lock pin 11 is identical with the length of pin key seat 16, and interlock dead bolt 14 is identical with the length of lock bolt sleeve 8.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.
