Description
The device of being pried open by force for a kind of rolling door that is used to prevent locking is newly moulded in this practicality.
Go up widely used rolling door now in the street, locking bar span flexible about reason tapered end control very big (equal curtain body width half), very easily prized from the insertion of the rolling door lower edge of locking with ripping bar, locking bar bending, locking bar top are opened door from skidding off within the walls by the lawless person.The shop that has adopts the way that adds bright lock on the rolling door in the hope of improving safety, and this not only uses inconvenience, and bright lock is also easily removed.So far still do not have a kind of device and can solve an above-mentioned pick-proof difficult problem.
The purpose of this utility model provides the device that a kind of rolling door that can prevent locking is pried open by force.
The structure that this practicality is newly moulded is as follows: the fastening lock pin in the termination of common rolling door locking bar, make itself and former locking bar termination form a T-head, locking bar to face wall on corresponding positions install a lockhole, in the hole top, the place ahead of lock pin position, back is provided with one downward opening, width greater than the narrow groove of locking bar thickness less than lock pin length in the patchhole of locking bar termination, is provided with a spring leaf at rear, narrow channel opening place.After rolling door was put down and locked, the T-head of locking bar termination inserted in the lockhole, and door is lockable, this hour locking lever by spring leaf prop up can not on move up into narrow groove.If there is external force to prize locking bar, then locking bar will overcome spring leaf pressure and on move up in the narrow groove, lock pin will make locking bar can not be crooked, the locking bar termination can not skid off by self-locking hole, door can not be opened.
Good effect of the present utility model has provided the device that a kind of rolling door that can prevent locking is pried open by force, and easy to use and reliable, and cost simple in structure is low.
Accompanying drawing is the structural representation of embodiment.
Embodiment: see accompanying drawing.In the lockhole 1 in the termination patchhole of top, locking bar 3 the place ahead of lock pin 2 positions, back be provided with one downward opening, width greater than the thickness of locking bar 3 narrow groove 4 less than the length of lock pin 2, be provided with a spring leaf 5 at the opening part rear of narrow groove 4, spring leaf 5 usefulness screws 6 are anchored on the dividing plate 7 in the lockhole 1.8 is shielding plate, and it can block foreign matter, it can not be filled in block the opening of narrow groove 4 in the lockhole 1 and make the device loss of function.9 is the hole of last expansion bolt, and lockhole 1 is anchored on the wall by expansion bolt.Lock pin 2 is welded on the locking bar 3.Lock pin 2 that with dashed lines draws among the figure and locking bar 3 are in the position behind the rolling door locking.Two of the pick-proof snap closes of each rolling door adapted present embodiment, each one of left and right sides locking bar.
