Problems solved by technology
[0003] However, the above-mentioned locking link is made of metal rectangular slats. When installing, it needs to cut and bend one side according to the width of the rolling shutter door, and connect it to the connecting accessories. Therefore, not only the production is cumbersome, but also there is a problem of high cost.
[0004] Secondly, if someone else applies an external force to the rolling door for the purpose of stealing or destroying, the center of the rolling door will be recessed inward, and at the same time, the protruding part of the locking link will break away from the lock hole on the keyhole plate to open the rolling door. The key can also open the disadvantages of the shutter door upwards

The invention provides a locking structure of the locking device of a rolling door. The locking lever of the locking mechanism is made into a short lever, such that the locking lever moves inwards and outwards under the action of a movable support, the central part of the locking lever is connected to one end of the movable support via a spring, the protrusion part of the locking level is inserted into a lockhole under the effect of the spring, one side of the locking lever is connected to a connection accessory capable of moving inwards and outwards and a steel wire, the steel wire is tightened by a key, at the same time, the protrusion part is detached from the lockhole, a stop member is formed on one side of the movable support, therefore the protrusion part is prevented from being detached from the lockhole even if the rolling door deforms under external pressure or the steel wire is tightened frontward and backward. The invention aims to provide a locking mechanism, which has low cost, simple manufacture process, and may be mounted simply and freely. The invention also aims to prevent others from invading, since the locking mechanism is provided with a stop member, the protrusion part of the locking lever can not be detached from the lockhole even if others meaning to steal or damage applies force to the rolling door.
Description
technical field [0001] The present invention relates to a locking structure of a locking device for a rolling shutter door. The locking protrusion that moves inside and outside the connecting attachment is inserted into / disengaged from the lock hole to control the closing or opening of the rolling shutter door. Specifically, the locking connecting rod is made into a short rod, and The connection accessories are connected with the wire rope for easy installation and setting, and multiple blocking parts are added to prevent the lock from opening even if external pressure is applied. Background technique [0002] Generally speaking, the locking device of the rolling shutter door is installed and fixed in the middle of the rolling shutter door. It consists of various structures with key functions, a lock box that can move inside and outside to connect the accessories, and a lock box that is connected with the locking accessories to move inside and outside. The locking connecting...
